Problems solved by technology

This application can improve the impact resistance of the detection mechanism to a certain extent through the installation of the damping mechanism, but the detection accuracy and structural stability of the detection mechanism still need to be further improved
At the same time, the device cannot control the height of the scratch bar of the parallelogram mechanism. When the height of the wheel rim is different due to wear, there may be no contact or too much contact between the wheel rim and the scratch bar, resulting in no measurement results or damage to the mechanism. The problem that a large impact will affect the measurement and even damage the mechanism

Embodiment 1

[0061] combine figure 1 , a contact method wheel runout detection system of the present embodiment includes a front mechanism 13 and a detection mechanism installed sequentially on the inner side of the track along the direction of train storage, wherein the front mechanism 13 is used to measure the rim height of the wheel to be detected. Detection, the detection mechanism is used to detect the radial runout of the wheel. Both the detection mechanism and the front-end mechanism 13 are connected to the control system, and the start and stop of the front-end mechanism 13 and the detection mechanism are controlled by the control system.

[0062] In this embodiment, a front-end mechanism is added in front of the detection mechanism (the direction of the train entering the warehouse), and the rim height of the wheel to be detected is measured by the front-end mechanism 13, and according to the measured rim height and the current position of the detection mechanism, through The con...

Embodiment 2

[0070] The structure of the contact method wheel runout detection system in this embodiment is basically the same as in Embodiment 1, the main difference is that the detection mechanism in this embodiment is symmetrically installed on the inner side of the double-sided track, and the number of detection mechanisms on the same side is ≥ 2 , and the sum of the lengths of the detection mechanisms on each side is greater than the circumference of the wheel, so that it can not only ensure the detection of the circumferential data of the wheel tread that is greater than the circumference of the wheel, but also meet the requirements for the detection of different front and rear wheels, and prevent the previous wheel from failing. The impact of leaving the detection mechanism and the next wheel entering the detection mechanism on the detection result. Wherein, the first detection mechanism maintains a certain distance from the front mechanism 13, and the time taken by the wheel to trav...

Embodiment 3

[0073] A contact method wheel runout detection system of this embodiment is basically the same in structure as Embodiment 2, the main difference is that this embodiment also includes a base plate assembly 5, which is fixedly installed under the track 1, and fixed The plate assembly 4 , the lifting drive mechanism 6 and the guide post guide sleeve mechanism 11 are all fixedly installed on the base plate assembly 5 . Such as Figure 14 As shown, the guide post guide sleeve mechanism 11 of this embodiment includes a base 1101, a guide sleeve 1102 and a guide post 1104, wherein the base 1101 is fixedly installed on the bottom plate assembly 5, and the guide sleeve 1102 is fixedly installed on the upper part of the first sliding plate 301 , the bottom of the guide post 1104 is fixedly installed on the base 1101, and its upper part passes through the guide sleeve 1102, and an inner liner 1103 is provided between the guide sleeve 1102 and the guide post 1104, and the inner liner 1103...

Abstract

The invention discloses a contact method wheel radial run-out detection system and method, and belongs to the technical field of rail transit. The invention discloses an online dynamic detection system which comprises a front mechanism and a detection mechanism that are sequentially installed on the inner side of a rail in the train warehousing direction. The detection mechanism comprises a pedalassembly, a first sliding plate and a fixed plate assembly which are mounted on the inner side of the rail and are parallel to one another, and a guide pillar and guide sleeve mechanism, wherein the first sliding plate penetrates through the guide pillar and guide sleeve mechanism and is in sliding connection with the pedal assembly and the fixed plate assembly through a sliding rail mechanism, the first sliding plate is connected with a lifting driving mechanism, and an elastic element is arranged between the first sliding plate and the pedal assembly. By adopting the technical scheme, the radial run-out of the train can be dynamically detected in real time in the high-speed running state of the train, the detection precision is effectively improved compared with an existing detection mechanism, and the structural stability of the detection device is good.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and more specifically relates to a contact method wheel runout detection system and method. Background technique [0002] In railway operation, the running state of the running part, especially the wheel set, plays an important role in the safety of the train. Wheelset parameters that play an important role in safety include: rim wear, circumferential wear, tread abrasion, etc. When there are faults such as scratches, peeling, radial runout and rolling on the wheel tread, additional impact force will be generated on the rail during the operation of the train, which will reduce the life of the rail and even cause cracks and fractures in severe cases. While hitting the rails, the abrasion fault also brings impact to the vehicle itself, generates vibrations, and has a destructive effect on the vehicle bearings. [0003] Therefore, the detection of defects such as wheel tread radial runout is ...
