[0002] The running gear is the part of a railway vehicle that runs along the track under traction power. It is divided into the locomotive running gear and the EMU running gear. The function of the running gear is to ensure that the vehicle runs flexibly, safely, and smoothly along the rails and through curves, reliably withstand various forces acting on the vehicle and transmit them to the rails, mitigate the mutual impact between the vehicle and the rails, reduce vehicle vibration, ensure sufficient running stability and good running quality, and have a reliable braking mechanism to give the vehicle good braking effect. In order to improve the inspection efficiency of the track running gear, an inspection device is needed. However, existing inspection devices still have the following shortcomings:
[0003] When existing testing devices are in use, most of them only perform wear detection on the track running parts, which means that the track running parts do not have other flexible testing capabilities during the testing process. At the same time, they are not easy to adapt to specific usage environments for testing the track running parts, resulting in reduced practicality and efficiency of the testing devices.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a flexible contact type track running part wear detection device. Utility Model Content

A rail body is installed on the front side of the upper part of the detection platform, and a rangefinder body is set in the middle of the outside of the rail body. An ultrasonic flaw detector is installed on the left side of the upper part of the detection platform.
[0007] Furthermore, the number of the support columns is set to four, and two support columns form a group, and each group of support columns is symmetrically arranged on both sides of the lower end of the testing platform with respect to the central axis of the front of the testing platform.
[0008] Furthermore, the limiting frame is perpendicular to the detection table, and the limiting frame is fixedly connected to the detection table by bolts.
[0009] Furthermore, the movable slider is embedded in the limiting frame, and the movable slider is slidably connected to the limiting frame via a lead screw.
[0010] Furthermore, the outer side of the mounting block and the outer side of the receiving frame are horizontally distributed, and the receiving frame is elastically connected to the mounting block through a spring damping rod.
[0011] Furthermore, there are two spring damping rods, and the two spring damping rods are symmetrically arranged on both sides of the lower end of the mounting block with respect to the central axis of the front of the mounting block.
[0012] Furthermore, the internal dimensions of the rail body are adapted to the external dimensions of the wheel body, and the inner side of the rail body is in close contact with the outer side of the wheel body.

[0015] Beneficial effects:
[0016] 1. This utility model, through the setting of a spring damping rod, enables the flexible contact type track running part wear detection device to use. The servo motor drives the lead screw to rotate, causing the movable slider connected to the lead screw to move accordingly. This, in turn, drives the mounting block installed on the outside of the movable slider to adjust its position. The spring damping rod makes the receiving frame and the mounting block elastically connected. The drive motor drives the wheel body to rotate, allowing the wheel body to be worn. Furthermore, the spring damping rod increases the detection diversity in the wheel body detection process, improving the overall practicality and efficiency of the detection device.

A rangefinder is used to measure the distance between the worn wheel body and the wear, and the ultrasonic flaw detector is used to detect flaws in the wheel body. This further enhances the convenience and practicality of the detection device during use. Attached Figure Description
