The coupler buffer device is an important component of the railway vehicle and is directly related to the connection reliability, longitudinal dynamics and other performances of the railway vehicle. The height of the coupler of the railway vehicle refers to the distance between the horizontal center line of the coupler and the upper surface of the track. When the height difference of the two mutually connected couplers exceeds an allowable range, the reliability, the stability and the comfort of the train can be influenced, and even the running safety of the train is endangered. The national standard has strict requirements on the height, upwarp amount and drooping amount of the coupler of the railway vehicle, and the height of the coupler must be adjusted when the vehicle is manufactured, operated and overhauled so as to achieve the aim of safe operation of the vehicle.
CN208505189U discloses a coupler height prediction device for railway vehicles. The prediction device comprises a main scale, a wearing plate measuring scale and a supporting seat measuring scale; the wearing plate measuring scale and the supporting seat measuring scale are arranged up and down and are respectively arranged at the same side of the main scale. The device can be used for judging the height of the coupler after the coupler buffer device is assembled in advance in the assembling and adjusting processes of a vehicle underframe or a steel structure. If the height of the pre-judged car coupler does not meet the specification, the height of the underframe can be adjusted in advance; and the proper thickness of the coupler bearing seat wearing plate is predetermined, and then the proper coupler bearing seat wearing plate is selected. Therefore, the repeated labor of repairing and repeatedly replacing the car coupler supporting seat abrasion plate due to unqualified height tolerance of the car coupler after assembly can be avoided, and the product quality and the production efficiency are improved. However, as mentioned above, the height of the coupler still needs to be detected frequently during routine maintenance during the running of the vehicle.
Chinese patent application No. 200720140979.8 discloses a car coupler height measuring instrument, and it includes PLC control device, at least one displacement sensor and data display screen, PLC control device with displacement sensor and data display screen link to each other. After the displacement sensor collects data between the central line of the coupler to be measured and the rail plane, the PLC control device receives the data and calculates the height value between the central line of the coupler and the rail plane, and the data display screen displays the calculated height value. The coupler height measuring instrument uses the PLC and the sensor, is precise, but is easily influenced by the outside, such as temperature, humidity and charging amount, and is easily damaged. As the daily instrument that uses in the railway overhaul, the practicality is not high.
