Abstract
Description
Technical Field
[0001] This utility model relates to a wear inspection device, and more particularly to a wear inspection device for railway wheels. Background Technology
[0002] To ensure railway operation safety, improve passenger comfort, reduce railway operating costs, and enhance railway transportation efficiency, it is necessary to regularly inspect railway wheel wear. Railway wheel wear mainly includes flange thickness, rim thickness, tread peeling length, rolling width, and tread wear parameters. Currently, there is no dedicated railway wheel wear inspection device. The industry typically uses general-purpose wheel inspectors. Wheel inspectors can only measure actual values, and inspectors need to compare these values with the limit values specified in the maintenance procedures to determine whether the vehicle is qualified. This is inconvenient to use, inefficient, and the existing inspection equipment is bulky and difficult to carry when conducting inspections. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of the existing technology by providing a portable railway wheel wear inspection device that can detect multiple parameters of railway wheels. It is small in size, easy to carry, and convenient to use, and can effectively improve inspection efficiency.
[0004] The technical solution adopted by this utility model to achieve the above-mentioned objectives is as follows: a portable railway wheel wear inspection device, comprising a main body, a tread peeling length measuring scale, a rim thickness measuring scale, a flange thickness measuring scale, and a wheel width measuring scale. The main body is flat. The tread peeling length measuring scale is located on the left side of the main body and extends downward from the bottom end of the main body. The rim thickness measuring scale extends downward from the bottom end of the tread peeling length measuring scale. The inner side of the section of the tread peeling length measuring scale protruding from the main body and the inner side of the rim thickness measuring scale continuously form a reference positioning edge that can position the rim. The bottom edge of the main body extending horizontally to the right inside the reference positioning edge is the tread wear detection edge. The main body on the right side of the tread wear detection edge continues to extend to the right and downwards to form the flange thickness measuring plate. The flange thickness measuring plate is installed on the surface of the flange thickness measuring plate in a horizontal direction. The main body on the right side of the flange thickness measuring plate extends downwards to form a tread positioning head protruding on the lower right side of the flange thickness measuring plate. The distance D from the tread wear detection edge to the bottom of the tread positioning head in the vertical direction is the flange height. The rolling width measuring plate is set at the upper right side of the main body.
[0005] A further technical solution of this utility model is: a hanging hole is provided in the main body of the upper side of the flange thickness measuring plate and the inner side of the rolling width measuring plate, which penetrates the front and rear surfaces of the main body.
[0006] A further technical solution of this utility model is: the inner side of the tread positioning head is connected to the bottom right side of the wheel flange thickness measuring plate by a bevel, so that the tread positioning head is connected to the bottom right side of the main body in an acute angle.
[0007] A further technical solution of this utility model is: a slider is installed on the back of the wheel flange thickness measuring plate, the wheel flange thickness measuring gauge is installed on the front of the wheel flange thickness measuring plate, and the back of the wheel flange thickness measuring gauge is connected to the slider through the wheel flange thickness measuring plate via a connecting device. The wheel flange thickness measuring gauge can slide left and right relative to the slider, and a locking screw is provided on the back of the slider to fix the position of the wheel flange thickness measuring gauge.
[0008] A further technical solution of this utility model is: the scale line of the tread peel length measuring scale is set on the left edge of the tread peel length measuring scale, and the scale line of the rim thickness measuring scale is set on the right edge of the rim thickness measuring scale.
[0009] A further technical solution of this utility model is that the scale values of the wheel rim thickness measuring scale, wheel flange thickness measuring scale, and wheel width measuring scale are limit values.
[0010] This utility model provides a portable railway wheel wear inspection device with the following advantages: It can detect the flange thickness, rim thickness, tread peeling length, rolling width, and tread wear parameters of railway wheels, satisfying the need for multiple parameter detection or inspection. Furthermore, its simple and compact structure makes it easy to carry. Based on the maintenance limits of each parameter, the dimensions of the inspection area are directly set to the limit values. During inspection, it is only necessary to determine whether the inspection area is aligned with or touches the limit values of the inspection device, thus improving work efficiency, reducing weight, and lowering labor intensity, effectively improving inspection efficiency.
[0011] The portable railway wheel wear inspection device of this utility model will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation
[0016] like Figure 1 , Figure 2 As shown, this utility model discloses a portable railway wheel wear inspection device (hereinafter referred to as the "inspection device"), used to inspect whether the flange thickness, rim thickness, tread peeling length, rolling width, and tread wear parameters of railway wheels have reached their limits. This utility model includes a main body 10, a tread peeling length measuring scale 3, a rim thickness measuring scale 2, a flange thickness measuring scale 7, and a rolling width measuring scale 6. The main body 10 is flat and is a metal plate. The tread peeling length measuring scale 3, rim thickness measuring scale 2, flange thickness measuring scale 7, and rolling width measuring scale 6 are disposed on or connected to the main body 10.
[0017] like Figure 1 As shown, the tread peel length measuring gauge 3 is located on the left side of the main body 10, with its bottom end protruding from the bottom end of the main body 10 and extending downwards. The scale lines of the tread peel length measuring gauge 3 are located on the left edge of the tread peel length measuring gauge 3, and the scale values gradually increase from top to bottom, which is basically the same as a general length measuring gauge. The rim thickness measuring gauge 2 continues to extend downwards from the bottom end of the tread peel length measuring gauge 3. The scale lines of the rim thickness measuring gauge 2 are located on the right edge of the rim thickness measuring gauge 2, and the scale values adopt limit values. The inner side of the section of the tread peel length measuring gauge 3 protruding from the main body 10 and the inner side of the rim thickness measuring gauge 2 continuously form a reference positioning edge 1 that can position the rim. That is, the inner side of the section of the tread peel length measuring gauge 3 protruding from the main body 10 and the inner side of the rim thickness measuring gauge 2 are on the same vertical plane. When measuring the rim thickness and flange thickness, the reference positioning edge 1 is close to the inner surface of the rim.
[0018] like Figure 1 , 2As shown, the bottom edge of the main body 10 extending horizontally to the right inside the reference positioning edge 1 is the tread wear detection edge 4. The main body 10 on the right side of the tread wear detection edge 4 continues to extend to the right and downwards to form the rim thickness measuring scale mounting plate 9. The rim thickness measuring scale 7 extends horizontally and is mounted on the surface of the rim thickness measuring scale mounting plate 9. A slider 11 is mounted on the back of the rim thickness measuring scale mounting plate 9, and the rim thickness measuring scale 7 is mounted on the front of the rim thickness measuring scale mounting plate 9. The back of the rim thickness measuring scale 7 is connected to the slider 11 through the rim thickness measuring scale mounting plate 9 via a connecting device. The rim thickness measuring scale 7 can slide left and right relative to the slider 11. The back of the slider 11 is provided with a locking screw 12 to fix the position of the rim thickness measuring scale 7. The rim thickness measuring scale 7 can slide to the left and extend into the space below the tread wear detection edge 4. The scale value of the rim thickness measuring scale 7 also adopts the limit value. The main body 10 on the right side of the flange thickness measuring plate 9 extends downward to form a tread positioning head 8 protruding from the lower right side of the flange thickness measuring plate 9. The inner side of the tread positioning head 8 is connected to the bottom right side of the flange thickness measuring plate 9 via a bevel, making the tread positioning head 8 connected at an acute angle to the bottom right side of the main body 10. Using this structure, the tread positioning head 8 can be more stably positioned on the tread surface during inspection. The distance D from the vertical tread wear detection edge 4 to the bottom of the tread positioning head 8 is the flange height. The value of D varies for different train models; trains with the same D value can use the same type of inspection device.
[0019] like Figure 1 As shown, the lower right section of the main body 10 is a flat vertical surface, which can be used as a positioning surface for measuring the rolling width. The rolling width measuring ruler 6 is set at the upper right side of the main body 10, and the scale value of the rolling width measuring ruler 6 also adopts the limit value. In the main body 10, on the upper side of the flange thickness measuring ruler mounting plate 9 and the inner side of the rolling width measuring ruler 6, there are hanging holes 5 that penetrate the front and rear surfaces of the main body 10. The hanging holes 5 are used to hang the wear inspection device.
[0020] How to use:
[0021] 1. When checking the flange thickness, adjust the flange thickness gauge 7 (slide relative to the slider 11) to the corresponding size according to the limit, and then tighten the locking screw 12. Place the reference positioning edge 1 against the inner side of the rim and clamp it onto the wheel tread along the wheel axis. If the end of the flange thickness gauge 7 contacts the flange and the bottom end of the tread positioning head 8 does not contact or just contacts the wheel tread, then the flange thickness being measured is within the limit; otherwise, it exceeds the limit.
[0022] 2. When checking the tread wear, move the wheel flange thickness gauge 7 to the right and stop it, then tighten the locking screw 12. Place the reference positioning edge 1 against the inner side of the wheel rim and clamp it onto the wheel tread along the wheel axis. If the tread wear detection edge 4 touches the top of the wheel flange, the wear exceeds the limit; otherwise, it does not exceed the limit.
[0023] 3. When checking the rim thickness, move the rim thickness gauge 7 to the right and stop it, then tighten the locking screw 12. Place the reference positioning edge 1 against the inner side of the rim and clamp it onto the wheel tread along the wheel axis. After the bottom end of the tread positioning head 8 contacts the wheel tread, observe the relative position of the edge of the wheel rim thickness and the maximum rim thickness mark of the inspection device. When they are aligned, it is at the limit; when they are below, it is not at the limit.
[0024] 4. When checking the wheel width, place the detection part (right vertical face) of the inspection device against the wheel width and observe the relative position of the wheel width and the maximum value mark of the inspection device. When they are aligned, the limit has been reached; when they are below, the limit has not been reached.
[0025] 5. When checking the tread peel length, measure along the peel length direction with the tread peel length measuring ruler 3 and read the peel length directly from the scale.

Any modifications, equivalent substitutions, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
