Boom concrete pump truck technology innovation has become the focus of a new round of competition
China started the boom arm pump concrete pump started in the early 1980s, the initial is basically the introduction of spare parts assembly, or through the introduction of technology and trade combined with the introduction of technology and part of the introduction of part of the production model.
In the 1950s, China produced a mechanical concrete pump, due to the low level of technology at that time, production volume is very small, in the early 1980s, the total amount of domestic concrete pump truck is still less than 200 units, armored concrete pump The car is a blank. During this period, some large-scale concrete pouring projects in our country basically relied on imported equipment to a large extent.
Since the early 1980s, after more than 20 years of hard work, our country boom-type concrete pump truck has made considerable progress, design level, manufacturing capacity has been greatly improved. According to statistics, at present, China's concrete pump manufacturer has reached more than 100, located in all parts of the country. However, due to the technical level of various manufacturers, production technology, production capacity and other jagged product gap is also larger. At present, the strongest production capacity in China is the first tier represented by Sany Heavy Industry, Zoomlion, Xuzhou Heavy Industries and Futian Heavy Machinery. The second tier consists of Liaoning Hainuo, Hubei Construction Machinery, Anhui Xingma and Shanghai Hong Deli and other enterprises, their production accounted for more than 90% of the industry.
In recent years, China's boom-type concrete pump truck has developed rapidly. Although the product stability and technology are not as good as foreign products, it has made great strides over the products of the 20th century. In terms of cost performance, after-sales service and other aspects of our products have obvious competitive advantages, and more in line with the actual construction of the domestic situation.
Among them, Zoomlion, Sany Heavy Industry in the arm-type concrete pump truck research and development walk in front of peers. Zoomlion formulated the "concrete pump truck" standard, but also developed a remote maintenance and positioning system for pump trucks. Sany Heavy Industry concrete pump truck, whether in the pumping pressure, pumping displacement, or in terms of stability, reliability, etc., with well-known foreign brands comparable to the pump machinery products have been sold to the Middle East , North Africa and South Asia and other places.
As can be seen from the 123 patents issued by the State Patent Bureau, the patents obtained by the domestic pumping machinery mainly include the pumps, pump gates and pump control, hydraulic and electrical appliances, etc. This shows that the domestic enterprises' Research more attention, this is also the field of domestic pumping machinery is relatively weak. Followed by the pump spare parts and jib, the number of patents in the past 20 years, only more than 100, which also contains foreign companies to apply for a patent, which shows that China's armor-type pump business R & D investment is not enough. However, our country has strong technical research and development capabilities of companies such as Sany Heavy Industry and Zoomlion are increasing research and development, and achieved gratifying results.
Boom concrete pump all the major components of the show
Domestic boom-type concrete pump truck because of the late start, the past two years, domestic enterprises have stepped up the introduction of technology and quality control, design and development with independent intellectual property rights of boom-type concrete pump truck, technological innovation as a domestic boom-type concrete Booster pump development. The major components of the technological development trend also represents the development of the domestic boom truck concrete pump truck development.
Chassis diversified
The chassis engine powers the work and driving of boom-type concrete pump trucks. Therefore, the performance of the chassis engine directly affects the performance of boom-type concrete pump truck. Currently domestic boom-type concrete pump truck commonly used Volvo, Mercedes-Benz, Isuzu chassis, 2005 has made use of domestic chassis boom concrete pump truck to the market. With the increasingly mature domestic boom truck pump market, vehicle profit margins continue to decline, in order to meet the different needs of users, using domestic chassis and imported chassis boom concrete pump truck will own a place in the market .
Domestic boom-type concrete pump chassis almost all imported chassis. One Isuzu chassis technology is mature, perfect service in the country, the price is relatively cheap; Volvo and Mercedes-Benz chassis luxury appearance, driving comfort, high degree of automation, the use of diesel EFI technology, low fuel consumption. At present, the engine used in the domestic boom-type concrete pump truck chassis meets the Euro â…¡ or above standards, to meet the environmental requirements of large and medium-sized cities.
Structure more applicable
Boom concrete pump truck operation is often limited by the upper space, requiring the top of the boom when the boom is the lowest, 4-fold below the boom commonly used single folding type R or Z-type. More than 5 knuckles of jib due to space constraints, the general use of folding type RZ to achieve the boom to expand, Shoulong, applicability, mobility and flexibility to enhance, especially in the tunnel and indoor work construction, the efficiency is significantly improved. The length of the first domestic boom to 37m majority, the past two years have become increasingly longer trend, the next few years, with the increasing demand, there will be a longer boom concrete pump truck to the market. Boom concrete pump truck leg operations are often subject to space constraints, especially large jib concrete pump truck. Therefore, all manufacturers have to combine their own experience to find solutions. Therefore, the arm-type concrete pump truck leg design presents a personalized, diverse features. Currently on the market with dual swing and X-shaped legs mostly.
Longer fabric boom and more flexible outrigger structure are the major trends in the development of boom-type concrete pump trucks. Various types of folding are used in combination to make the boom design more flexible and lighter. The form of legs is also more and more flexible, the extensive use of unilateral legs, so that the boom concrete pump truck to adapt to different site conditions.
The center pumping system is more pressurized and delivers more
Higher pressure, greater transmission capacity will become the future development trend of pumping system of the domestic boom concrete pump truck center. In the initial stage of the design of domestic boom-type concrete pump truck, the diameter of concrete transportation is about 200mm, the output displacement mostly concentrates below 100m3 / h. Since 2004, the concrete delivery cylinder with the diameter of 200mm has exited the pump truck product, Pump products have applications. At present, the market is the most common transport bore 230mm, travel in 2100mm, or even longer, the output displacement of 120m3 / h or more. With the booms of boom-type concrete pump truck getting higher and higher, the models become bigger and bigger, and the cylinder diameter of the delivery cylinder is also getting larger and larger. The cylinder with the largest diameter in China has reached 260mm and the displacement of concrete is greater. However, From the overall configuration of the machine, due to the height of the machine and the width of the frame, the larger cylinder diameter concrete conveying cylinder is greatly restricted in the application of the arm type concrete pump truck. At the same time, the larger the cylinder diameter of the concrete delivery cylinder, the greater the output displacement, the greater the required chassis engine power will be, and the greater the vibration displacement of the boom will be when the whole machine is working in large displacement. Therefore, large-diameter arm-type concrete pump truck if you want to replace the common bore diameter of 230mm, but also do a lot of work, go a long way.
Due to the progress of the project requirements are getting higher and higher, now require pumping displacement of 80 ~ 120m3 / h more and more projects, large displacement will become the future development direction of boom-type concrete pump truck. In addition, pumping pressure is getting higher and higher. Before 1971, most of the concrete outlet pressure does not exceed 2.94MPa, later increased to 5.88 ~ 8.38MPa, has now reached 22MPa, but also continue to increase the trend.
Hydraulic system to the direction of integration
Hydraulic system is the core part of boom-type concrete pump truck. The quality of hydraulic system will directly affect the performance and efficiency of the host. Domestic arm-type concrete pump truck hydraulic system mostly imported technology design, there are 2 kinds of control circuit, a closed-loop hydraulic system to Xuzhou Heavy represented, the other is open hydraulic system circuit to Sany Heavy Industry to represent. Open circuit and closed circuit have their own advantages and disadvantages, closed circuit commutation impact is small, small heat, simple structure; and open circuit is the most prominent feature is able to easily control the pump displacement according to the load, in particular When pumping over short distances, the pumping capacity is large enough to take full advantage of the engine power. After years of experimental verification, these two kinds of hydraulic circuits have been relatively mature in the application of boom-type concrete pump truck, but have their own characteristics in achieving various functions, technically there is no problem of who is superior and who is inferior, Only in the selection of hydraulic components there are some differences.
Boom concrete pump truck commonly used open system and constant power control, especially the large flow pump, open system with low oil temperature, high reliability, easy maintenance and many other advantages. At the same time, the whole hydraulic control technology, computer control technology has made a breakthrough. Such as Sany Heavy Industry Products hydraulic steering and computer closed-loop control technology has been widely used.
Control system more features
Electrical control is the key to determining the efficiency of a pump truck. Boom concrete pump truck electrical system developed rapidly in the past two years, all domestic manufacturers have been from the initial relay control for the PLC control, greatly improving the reliability of the product.
Boom concrete pump truck electric control system from the traditional PLC control to the dedicated controller and computer intelligent control of the development, through the touch screen, you can achieve man-machine dialogue, a variety of operating parameters can be stored and displayed to achieve the vehicle's auto monitor. Once the machine running failure, in addition to alarm tips can also be transferred to the relevant parameters for fault analysis, diagnosis. The application of boom intelligent control system technology can realize the luffing of boom with the same level and intelligent pouring.
Technological innovation has become the focus of a new round of competition
With the intensification of market competition, the development trend of domestic boom concrete pump trucks directly affects the development of domestic manufacturers. How to grasp this trend has become the focus of the domestic boom-type concrete pump truck manufacturers
Domestic boom concrete pump truck developed rapidly in our country, more and more functions, more and more superior performance, reliable. PLC control, automatic electric displacement control, automatic load feedback control, high and low pressure automatic switching has gradually become the standard armor concrete pump truck manufacturers. At the same time, the development of pumps with mixing drums, jetting machines and other auxiliary devices such as cloth truck will be the development direction of domestic boom concrete pump truck.
Boom concrete pump truck in our country so far, the product has matured, the system will not be a big problem. After the hot competition will be reflected in the improvement of function and reliability, reflected in some design details, some seemingly insignificant issues, will be able to further develop in the market, or even the decisive factor for survival. The use of ergonomic design, focus on operational performance, improve the working environment for the operator to improve comfort, reduce noise and vibration, embody the people-oriented features to increase the appearance of design, which will be our future for quite a long time Research topic At the same time, we must pay more attention to environmental protection and health, and truly reflect the principle of "safety, environmental protection, reliability and advancedity."
With the continuous improvement of construction conditions and the environment, as well as the continuous development of manufacturing technology boom, long boom, high-efficiency arm-type concrete pump truck will be more and more users, in the next 3 to 5 years, The demand for pump trucks under the arm length of 40m will decrease. The truck with a boom length of 45m and 48m will become the mainstream in the market. For example, Sany Heavy Industry has developed a boom-type concrete pump truck with a boom length of 65m, becoming The world can produce the longest boom concrete pump truck business. In addition, intelligent control system technology will become the universal accessories for boom-type concrete pump trucks. The expansion of pumping capacity and its use in other pumping applications will also be one of the trends in boom-type concrete pump trucks.
At present, the competitive focus of domestically produced boom-type concrete pump trucks is firstly the technical level of the products, such as the manufacturing technology of the boom, including the structure, support, boom deployment mode, stability and service life. Manufacturers in the basic research while focusing on technological innovation, continuous improvement in product quality and performance based on the promotion of product upgrading; followed by the reliability, maintainability and operating costs and other advantages of competition; third is the marketing competitiveness, Including the marketing model in different stages of market innovation; the last is the competition in services, improve the service network and service capabilities to become an important reference for the user to select the device. The ability of service personnel and training of service personnel, that is, the improvement of service capability has become a key task for enterprises.
Boom concrete pump truck to a more complete specifications, higher grades, fabric boom longer direction, the boom from the past 37m for the mainstream, and gradually transition to 42 ~ 45m mainly to 47 ~ 56m direction . Improve equipment energy conservation, environmental performance is also a big trend, the engine gradually replaced by air cooling water cooling, most of the emission standards to Europe â…¡ or Europe â…¢ standards. Self-testing, self-protection, self-tuning and multi-sensing technology, constant power control technology and GPS positioning technology will also become the mainstream of development; while driving will be more humane.
Domestic boom-type concrete pump truck manufacturers are mostly modeled on several major foreign manufacturers, the general arm length to 36 ~ 58m-based, while the arm length of less than 36m jib concrete pump truck almost no production. Domestic enterprises in pursuit of large, refined, special as the goal, strive to become the industry leader, in order to enhance the visibility of enterprises and display business capabilities, but at the same time often neglected the serialization of products and practicality, to some extent from the China's national conditions. At present, large-size concrete pumping projects in large and medium-sized cities mostly use boom-type concrete pump trucks with arm lengths of more than 36m, while some small-scale municipal projects and construction projects often do not require long-boom concrete pump trucks. Short boom (less than 36m arm length) concrete pump truck has all the features of long boom concrete pump truck, but abandoned the long boom concrete pump truck cost, limited by the use of space and other shortcomings, while dragging Concrete pump, vehicle pump is more flexible, simple operation, high efficiency and other advantages, as a new direction for the development of the pump truck industry. In addition, short boom concrete pump truck due to low prices, low cost and other factors are also very suitable for private investment.
Domestic concrete machinery and more use of European components, such as hydraulic pumps, valves, boom, etc., while Japan has some advantages in electrical and control systems. In concrete pumping products, the use of Omron or Siemens PLC programmable logic controller, Germany's Rexroth hydraulic parts, but also the selection Kawasaki K3V series hydraulic pump or hydraulic valve parts, but a small number of other accessories and more made in China Mainly. Domestic concrete machinery manufacturers should absorb, digest and utilize foreign advanced technology as soon as possible, on this basis, apply our ideas and ideas to their own research and development of pumping machinery in order to constantly improve the technological content of domestic equipment.
User choice more rational
Users are more and more demanding on the functional requirements of boom-type concrete pump trucks, when choosing products, they no longer simply consider the price factors. Therefore, how manufacturers make technological innovation to meet the needs of users is a new topic
Through the use of domestic boom-type concrete pump truck situation, the domestic boom-type concrete pump truck basically meet the technical requirements of the current pumping requirements, with the gap between foreign brands become smaller and smaller. We buy boom-type concrete pump is valued for the cost-effective equipment and service capabilities of manufacturers, especially in large concrete pouring project, equipment reliability and service capabilities of manufacturers will be higher. Because once the equipment fails and can not be ruled out in time, not only our interests are affected, at the same time may not make a good project completely scrapped. Although the reliability of foreign equipment is relatively high, but the ability to supply parts really can not be flattering. Therefore, under the same conditions, we will choose cost-effective, better service domestic boom concrete pump truck. In the course of using, the only feeling that domestic boom-type concrete pump is insufficient is that wearing parts have a relatively short life cycle, which to a certain extent, increases our cost of use. It is suggested that domestic manufacturers should spend more time on wearing parts to improve their service life.
Users should first choose a stable performance of the brand, that is, product reliability, ease of maintenance. At the same time should also be manufacturers of network services capabilities, spare parts supply capacity and training have enough understanding of the service value creation should become the user's consensus. Second, users should consider the construction requirements, select the appropriate boom length, displacement and adequate outlet pressure to meet the construction height and pumping performance requirements. Finally, the user should choose the right chassis according to his actual situation, considering the factors such as the cost performance and operating cost of the equipment purchased.
Domestic boom-type concrete pump truck relative imports boom-type concrete pump truck biggest advantage than its perfect after-sales service and spare parts supply. From the survey of several large mixing station feedback point of view, domestic equipment manufacturers 24 hours a day service, meticulous and careful pre-sale and sale of services are more humane, and even in the event of equipment failure, will provide free substitutes for the user Use, greatly reducing the user's purchase risk and operating costs. Its rich supply of accessories is also relished by users.
From the point of view of use, the domestic boom concrete pump truck has now reached the level of foreign countries in the 1990s, and the overall performance of boom-type concrete pump truck is increasing year by year, the failure rate gradually reduced, the cost of use also dropped a lot . In addition, the domestic arm-type concrete pump truck in the configuration and the imported equipment is not much difference, most of the imported chassis, hydraulic system, the key components of electrical systems are imported equipment with the same brand, the quality of the pumping system has many years of technology As a safeguard, jib and other structural materials and welding quality have passed. However, the use of the machine is still a gap with foreign products, the combination should still enhance the matching design. Domestic boom-type concrete pump truck relative to the biggest advantage of imported pump truck lies in its perfect after-sales service and spare parts supply, if domestic manufacturers can in this kind of advantage, through technological innovation and strengthening the production process management, improve the quality of the whole machine , Will make the domestic boom-type concrete by the user's favor.
In the 1950s, China produced a mechanical concrete pump, due to the low level of technology at that time, production volume is very small, in the early 1980s, the total amount of domestic concrete pump truck is still less than 200 units, armored concrete pump The car is a blank.
