The friction coefficient test of the wheel and rail material can well know the situation of the wheel and rail in operation, which is convenient for risk investigation and material selection, so this device can be used when testing the friction coefficient of the wheel-rail material. First, place the device in the detection area, then place the wheel-rail material on the mounting plate 2, and start the lateral slide through the console 1 3 and the vertical slider 4, the vertical slider 4 presses down on the wheel-rail material, and the horizontal slider 3 drives the vertical slider 4 to move, so that the vertical slider 4 moves on the wheel-rail material to generate friction, By rubbing the vertical slider 4 with the wheel-rail material, the friction coefficient is transmitted to the console 1 for data conversion, and the friction coefficient of the wheel-rail material is recorded by observing the value displayed on the data display on the console 1 , in order to facilitate the multi-scenario simulation of the friction detection of the wheel-rail material, the pressure adjustment mechanism 5 of the device can be used. When the vertical slider 4 moves downward, it will drive the connecting frame 50 to move downward together.
