Description

Technical Field

[0001] This utility model relates to the field of rail train maintenance, specifically a gauge for measuring the travel gap of rail train limit switches. Background Technology

[0002] Limit switches, as position sensing devices for moving mechanical components of railcars, are responsible for monitoring the motion status of various moving parts of the train. Their travel clearance is a crucial technical parameter, making its accurate value essential. Currently, feeler gauges are primarily used to measure this travel clearance. However, the limit switches on railcars are installed inside a cover, and the space inside the cover is limited and complex, making it difficult for maintenance personnel to manually insert the feeler gauge into the target position for measurement. This results in prolonged operation time and inaccurate measurement data. Therefore, a new measuring tool is needed to solve these problems. Utility Model Content

[0003] The purpose of this utility model is to provide a gauge for measuring the gap of travel switches on rail trains, which can change the direction of the gauge head and obtain different measurement units through detachable gauge pieces to adapt to different measurement stroke requirements, as well as the internal spatial structure of the cover plate, in order to solve the above-mentioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a travel gap measuring ruler for rail train travel switches, comprising a handle, a buckle assembly, and a feeler gauge head assembly.

[0005] Furthermore, one end of the handle is provided with a through hole group and a mounting groove.

[0006] Furthermore, the buckle assembly includes a male connector, a female connector, a plug, and a slot.

[0007] Furthermore, the feeler gauge head assembly includes a base, a feeler plate, and a pin.

[0008] Furthermore, one end of the base is provided with a through hole A.

[0009] Furthermore, the other end of the base is provided with a pin hole.

[0010] Furthermore, the plug includes a through hole B.

[0011] Furthermore, the feeler gauge head assembly is connected to the handle via the snap-fit ​​assembly, and the feeler gauge head assembly can rotate within the mounting slot.

[0012] Furthermore, the plug is connected to the base body via the pin, pin hole, and through hole B, allowing the plug to be flipped.

[0013] The beneficial effects of this utility model are: the travel gap measuring ruler for rail train travel switches can change the direction of the feeler gauge head assembly, so that this utility model can adapt to the spatial layout inside the cover plate. The thickness of the base itself can provide a basic measuring unit. Through the detachable feeler plate, this utility model can obtain different measuring units to adapt to the requirements of different measuring strokes, thereby improving work efficiency and data accuracy.
