Description

Technical Field

[0001] The utility model relates to the field of inspection tools, in particular to a special inspection tool for measuring the center height of a locomotive and vehicle coupler. Background Art

[0002] The coupler is an important part for connecting locomotives and vehicles, and vehicles and vehicles of rail transportation equipment such as trucks and passenger cars, so it needs to be inspected regularly. Usually, the center height of the coupler is measured to determine whether the coupler meets the safety standards. Since the coupler height measuring ruler will deform and wear after repeated use, the accuracy will be inaccurate.

[0003] To this end, a utility model patent for a vehicle coupler center height gauge (publication number: CN207832078U) is disclosed in the prior art, which detects the accuracy of the coupler height gauge through a support seat, a ruler, a ruler frame sliding in the ruler, and a probe fixed on the ruler frame. However, such a gauge has a single function and cannot simultaneously detect the plane verticality of the coupler height gauge, resulting in inconvenient detection and incomplete data. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a special gauge for measuring the center height of a locomotive and vehicle coupler, which is convenient for users to use and improves the detection accuracy and the comprehensiveness of the detection data.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a special gauge for measuring the center height of a coupler of a locomotive vehicle, comprising a support seat and a ruler fixedly mounted vertically upward on the support seat, a slide rail being provided on the ruler, a vernier scale frame being sleeved on the slide rail, a small scale frame being fixedly mounted on the vernier scale frame, a matching small scale being slidably mounted on the small scale frame, the small scale being perpendicular to the longitudinal direction of the ruler and being able to slide along the vertical direction, the small scale having a measuring end and a reading end, the coincidence line between the reading end and the vernier scale frame being the measured value.

[0006] Furthermore, the vernier scale frame is provided with a protruding probe in the measuring direction.

[0007] Furthermore, the positions of the vernier scale frame and the small scale are fixed by screws during measurement.

[0008] Furthermore, the measuring end is a trapezoidal structure.

[0009] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0010] The special gauge for measuring the center height of the coupler of a locomotive and vehicle can calculate the plane error value by installing a small scale frame and a small scale on the vernier scale frame and sliding the small scale close to the coupler height scale to be tested. This adds the function of testing the plane verticality of the coupler height scale, making it convenient for users to collect more data and making the test result more accurate. The measuring end of the small scale is set to a trapezoidal structure, making it easier for users to align the test position. The trapezoidal structure has a smaller test contact area during testing and a more accurate value. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] When detecting the relative verticality of the coupler center height measuring ruler 8, the coupler height measuring ruler 8 and the special gauge for the coupler center height measuring ruler of locomotive and vehicle are placed on the second-level flat plate, and the measuring end 401 of the small ruler 4 of the gauge is respectively pressed against the front face and the engraved surface of the coupler height measuring ruler 8. At the positions of about 650mm and 950mm of the coupler height measuring ruler 8, the readings of the reading end 402 of the small ruler 4 of the gauge are respectively read after tightening the screw 7. The values ​​at the two positions are subtracted, which is the verticality of the coupler height measuring ruler 8. If the verticality is not greater than 0.6mm, it is qualified, otherwise it is unqualified.
