Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of railway surveying technology, especially a car coupler height measuring tool. BACKGROUND

[0002] The car coupler is a hook at the two ends of a train car or a locomotive, which has the functions of connection, traction and buffering. The car coupler is used to realize the connection between a locomotive and a vehicle or between vehicles, to transmit traction and impact forces, and to keep a certain distance between vehicles. Before a train is delivered, the installation height of the car coupler needs to be measured. The delivery height limit of the car coupler is 880±10mm (according to TB / T3044-2002 TB / T3046-2002), that is, the height of the car coupler of the same vehicle should not differ by more than 10mm. When the height of the car coupler exceeds the allowable error range, the stress area of the hook tongue connected by the car coupler will decrease, which may cause the natural separation of the car coupler and lead to the uncoupling accident, endangering the safety of train operation and causing serious loss of life and property.

[0003] At present, the height of the car coupler is mostly measured by using a steel tape measure. One maintenance personnel needs to place the initial position of the tape measure at the measurement position of the car coupler so that the tape measure is vertically free, and the other maintenance personnel reads the data of the contact between the lower surface of the auxiliary square steel and the tape measure as the height of the car coupler. Although this method is convenient, the measurement accuracy is not high and there is an error. Therefore, it is necessary to provide a car coupler height measuring tool to solve the above technical problems.

[0004] Through the above analysis, the problems and defects of the prior art are as follows:

[0005] At present, the height of the car coupler is mainly measured by using a steel tape measure.

At the same time, the reading of the tape measure depends on the eyesight and experience of the maintenance personnel, and there may be reading errors between different personnel, increasing the uncertainty of measurement.
