[0028] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0029] Figure 2 It is a structural schematic diagram of a measuring tool of a preferred embodiment of the utility model; Figure 3 It is a reference diagram of the use status of the measuring tool of the preferred embodiment of the utility model.

[0030] like Figure 2 and Figure 3 As shown, the rail gauge line straightness measuring tool of this embodiment includes:

[0031] A base 1, which is used to be set against the target rail and serve as a bottom reference;

[0032] Measuring component 4, used for detecting the straightness of the gauge line of the target rail;

[0033] A height adjustment mechanism, disposed on the base 1 and connected to the measuring member 4, for adjusting the measuring member 4 to a target height to match the height of the gauge line of the target rail;

[0034] The horizontal adjustment mechanism is respectively connected to the height adjustment mechanism and the measuring member 4, and is used for adjusting the distance between the measuring member 4 and the target rail in the horizontal direction.

[0035] The measuring member 4 of this embodiment is a triangular flat ruler, so that it is in line contact with the track gauge line;

[0036] It can be understood that the rail gauge line straightness measuring tool sets the base 1 as the bottom reference and sets the height adjustment mechanism so that the height position of the measuring piece 4 matches the height position of the gauge line and is accurately positioned at the gauge line position. The measuring piece 4 is moved to contact the rail track line through the horizontal adjustment mechanism, and a triangular straight ruler is used as the measuring piece 4 to make it in line contact with the gauge line, thereby ensuring the accuracy of the measurement position, avoiding inaccurate measurement data caused by the width of the straight ruler, and effectively solving the problem that the starting point position of the planing of the point rail and the heart rail cannot be measured and it is difficult to accurately find the gauge line position.

[0037] In this embodiment, a magnetic part is provided on the base 1 for adsorbing the base 1 to the target rail. The base 1 is L-shaped as a whole, and can fit the bottom and side of the rail and adsorb, so that the reference line of the base 1 is flush with the bottom of the rail; in other embodiments, the base 1 can also be positioned to match the rail by setting a snap structure.

[0038] In this embodiment, the height adjustment mechanism includes a stand 2 and a connecting section 11 and a guide section 12 vertically arranged on the base 1. The stand 2 is provided with a connecting rod 21 for cooperating with the connecting section 11 and a guide rod 22 for cooperating with the guide section 12. A height mark is provided on the connecting rod 21 and / or the connecting section 11; for example, in this embodiment, the connecting section 11 and the guide section 12 are tubular, the connecting rod 21 is passed through the connecting section 11, and the guide rod 22 is passed through the guide section 12. The height mark can be a scale line respectively provided on the connecting section 11 and the connecting rod 21. The stand 2 is moved and guided and restricted in movement under the action of the connecting section 11 and the guide section 12, so that the stand 2 remains parallel to the rail during the height adjustment process, and then the measuring piece 4 is parallel to the gauge line when it is translated to the gauge line position, and the positioning is accurate and the measurement is precise;

[0039] In this embodiment, the height adjustment mechanism also includes a limiting mechanism for limiting the movement range of the connecting rod 21 relative to the connecting section 11. The limiting mechanism includes a first limiting block 13 set at a preset height of the connecting section 11 and a second limiting block 23 (preferably an end portion) set at a preset height on the connecting rod 21 to limit the connecting rod 21 from moving out of the connecting section 11. The first limiting block 13 and / or the second limiting block 23 should be a detachable structure.

[0040] In this embodiment, the height adjustment mechanism further includes a fixing mechanism 5, which is used to fix the guide rod 22 to the guide section 12. The fixing mechanism 5 in this embodiment is a screw threadedly connected to the side wall of the connecting section 11, and the locking screw abuts against the guide rod 22 to achieve locking and fixing of the stand 2 at the target height;

[0041] In this embodiment, the connecting section 11 is arranged in the middle of the base 1, and the guiding sections 12 are arranged at both ends of the base 1 to guide the movement of the stand 2 to avoid deviation. Its height mark is located in the middle of its tooling, and the measurement is more accurate. Specifically, the horizontal adjustment mechanism includes an adjustment rod 3 passing through the stand 2, and the end of the adjustment rod 3 facing the target rail is connected to the measuring piece 4. By pushing the adjustment rod 3, the measuring piece 4 is moved toward the rail direction so that the measuring piece 4 is in contact with the gauge line for measurement.

[0042] The stand 2 is provided with a mounting groove 24 for inserting the adjusting rod 3. The width of the mounting groove 24 is greater than the width of the adjusting rod 3. The adjusting rod 3 is hinged to the measuring piece 4. The thickness of the adjusting rod 3 matches the height of the mounting groove 24 to avoid offset and inaccurate height position. The width of the mounting groove 24 is greater than the width of the adjusting rod 3. The adjusting rod 3 is hinged to the measuring piece 4, so that the adjusting rod 3 has a certain horizontal range of movement space, and each adjusting rod 3 can be pushed in turn so that the measuring piece 4 can be adjusted to a certain angle within the horizontal range to fit the track gauge line, which is easy to operate and accurate in measurement.

[0043] In this embodiment, one end of the adjusting rod 3 away from the target rail protrudes to form a limiting structure 31, and the sum of the thickness of the limiting structure 31 and the thickness of the adjusting rod 3 is greater than the height of the mounting groove 24, which effectively prevents the adjusting rod 3 from detaching from the frame 2 during movement and ensures structural stability.

For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
