Abstract

The invention provides a universal rail top roughness tester. The universal rail top roughness tester comprises a long transverse limit baffle, a spring, a groove component, a slider, a guide rail, a motor, a vertical limit baffle, a pulley, an accelerated speed sensor, a probe and a short transverse limit baffle, wherein the motor and the pulley are fixedly mounted on the guide rail; the slider is driven by a motor of the motor to rotate, so that the slider on which the accelerated speed sensor is mounted is driven to move on the guide rail; the probe is tightened below the accelerated speed sensor, and the accelerated speed sensor is mounted in the groove component; the spring is positioned between the groove component and the slider; the vertical limit baffle, the long transverse limit baffle and the short transverse limit baffle are selected according to different dimensions of rails, the guide rail is mounted above the rail, the probe is in contact with the top surface of the rail, and the spring has certain pre-tightened force. The roughness tester can be conveniently mounted on and disassembled from universal rails of different dimensions, can meet the requirement of automation and can repeatedly test the roughness of rail tops.

Description

technical field [0001] The invention relates to the technical field of measuring the roughness of the top surface of a rail, in particular, the invention relates to a universal roughness tester for the top surface of a rail. Background technique [0002] In the prior art, when measuring the roughness of the top surface of the track, there are mainly two ways, one is to fix a reference beam on the track, use a moving probe to move along the track, and measure the relative distance between the reference beam and the top surface of the track. The position, and then the roughness of the top surface of the track. In this way, the measuring equipment must be fixed for each measurement, so the preparation time is long, the equipment is very inconvenient to use, and the efficiency is very low. The other is based on the trolley, which allows the trolley to move along the track and measure the relatively long track distance. However, this measurement method requires one person to pu...
