Shanghai Metrology Institute obtains patent for invention of "wheel wheel diameter detection device"

[ Instrument Network Instrument R & D ] Recently, Shanghai Metrology Institute has developed a device for on-site detection of wheel diameter of rail transit wheels. This research achievement application has obtained the invention patent authorization in the field of rail transit detection, which has improved the technical level of Shanghai Metrology Institute in the field of rail transit detection, and has helped to better serve the city's rail transit system and meet the metro's standard wheelset geometric parameter measurement. Demand.

At present, Shanghai is in a critical period of resumption of work and production. Rail transportation is an important means of transportation for citizens, and its safe and stable operation is the key to ensuring the full restoration of production and living order. For a long time, Shanghai Metrology Institute is committed to providing high-quality metrological testing services for the city's rail transit. Engineers in Shanghai Metrology Institute found that during the test of subway standard wheel sets, samples are often scattered in various maintenance bases of subway companies, which are relatively large and heavy. It is heavy and inconvenient to transport, and is not suitable for routine delivery to a laboratory for testing. After in-depth research and discussion, engineers from Shanghai Metrology Institute designed a set of on-site testing devices to successfully solve the on-site testing problems of standard wheelset geometric parameters. Compared with the traditional detection method, the device reduces the number of measuring tools, improves the detection efficiency, greatly reduces the work intensity and improves the measurement accuracy (equipment measurement accuracy can reach 0.03mm, which is better than the high-speed rail 0.15mm technical requirements).

After the equipment was put into use, it was highly evaluated by Shanghai Metro. In the future, Shanghai Metrology Institute will continue to overcome difficulties in the field of rail transit detection, add bricks and tiles to the construction of Shanghai Rail Transit, and escort the citizens of Shanghai.
