In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] like Figs. 1-3 As shown, a scribing fixture for detecting wheel pressure on a track includes a left fitting portion 5 and a right fitting portion 6. The left fitting portion 5 includes a left integral structure that fits the track, an insertion hole 1 on the left integral structure, and a first scribing hole 3 for scribing. The first scribing hole 3 is located in the middle part of the left fitting portion 5 corresponding to the track side. The right fitting portion 6 includes a right integral structure that fits the track, an insertion protrusion 2 on the right integral structure, and a second scribing hole 4 for scribing. The second scribing hole 4 is located in the middle part of the right fitting portion 6 corresponding to the track side.

[0026] The left fitting part 5 and the right fitting part 6 cooperate with each other. After the insertion protrusion 2 is inserted into the insertion hole 1, they form a whole. The insertion protrusion 2 can be set as a strip shape. The insertion hole 1 is a through hole, which is easy to clean and prevents coal dust, mud and other substances from entering and accumulating inside, affecting the insertion effect. The overall shape after insertion is adapted to the track surface. The left fitting part 5 and the right fitting part 6 are at the same height.

[0027] Specifically, both the first scribe hole 3 and the second scribe hole 4 are isosceles right triangles, with their right-angle vertices located at the center of the side of the track and correspondingly positioned on both sides of the track. Considering that single pieces and decorative pieces are sometimes used to detect wheel pressure, one right-angle side of the first scribe hole 3 and the second scribe hole 4 are horizontally positioned on the same cross-section of the track as the base. The two bases are at the same height from the bottom of the fixture, and the right-angle orientations of the first scribe hole 3 and the second scribe hole 4 are opposite, which is beneficial for the adhesion of decorative pieces. In addition, when scribes, right-angled triangles are convenient for horizontal and vertical positioning, and the durability of their intersection points is higher than that of cross-shaped openings, resulting in more accurate scribes.

[0028] In the embodiment, the left fitting part 5 and the right fitting part 6 are both integral structures with a width of 50 mm and a thickness of 5 mm; the plug-in hole 1 has a cross-section length of 40.01 mm and a width of 10.15 mm, and the plug-in protrusion 2 has a cross-section length of 40 mm and a width of 10.14 mm; the plug-in hole 1 and the plug-in protrusion 2 form an integral whole with a total thickness of 20 mm; the first scribe hole 3 and the second scribe hole 4 each have a right-angle side length of 20 mm.

[0029] The preparation method of the utility model is as follows:

[0030] Step one, draw the overall structure 5, 6 of the tool in AutoCAD;

[0031] Step two, dig out the plug-in hole 1 and draw the plug-in protrusion 2;

[0032] Step three, dig out the scribe holes 3, 4 in the form of isosceles right-angled triangles at the fitting positions of the track side surfaces;

[0033] Step four, 3D printing.

[0034] The working process of the utility model is as follows:

[0035] Before implementation, clean the track surface layer and side surface impurities and rust marks, and then adopt the plug-in mode to clamp the left fitting part and the right fitting part on both sides of the track, and use the scribe steel needle to scribe along the first scribe hole and the second scribe hole arranged correspondingly on the left and right sides, which can ensure that the scribed lines are symmetrical on the left and right sides, and at the same time, ensure the scribing precision, and provide good site conditions for the following patching step; when patching, only need to patch against the scribed position of the track side surface, so that the strain gauges on both sides of the track are symmetrical in height and cross-section direction along the track.

[0036] It should be noted that the above embodiment is only used to illustrate the utility model, but the utility model is not limited to the above embodiment, and any simple modification, equivalent change and modification according to the technical essence of the utility model to the above embodiment all fall within the protection scope of the utility model.
