Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of railway maintenance, in particular to a grounding wire clamp for railway maintenance. Background Art
[0002] Safety inspections are crucial in the daily operation and maintenance of railway systems. With the continuous development of railway transportation, higher requirements are being placed on the efficiency and safety of railway inspections. Currently, traditional grounding clamps present numerous problems in railway maintenance operations. For one thing, existing grounding clamps are often cumbersome to install and remove, consuming significant time and manpower. This not only reduces work efficiency but can also lead to equipment damage or delay maintenance due to improper operation.
[0003] On the other hand, traditional grounding clamps have poor locking performance and are prone to loosening during use. Due to the complex railway operating environment, such as vibration and wind caused by train movement, a loose grounding clamp poses a serious threat to the safety of maintenance personnel. A loose grounding clamp may not effectively connect to the ground, preventing the current from being conducted to the earth in a timely manner, increasing the risk of electric shock for maintenance personnel. Utility Model Content
[0004] The purpose of the utility model is to provide a grounding wire clamp for railway maintenance, which is used to solve the problems mentioned in the prior art in the above background technology.

[0006] Furthermore, the fastening ring includes a first nut threadedly matched with the thread groove and a slip ring provided on the side of the first nut close to the clamping block. The slip ring is passed through the clamping rod and has a plurality of sliding holes equidistantly spaced along the circumference.
[0007] Furthermore, the locking assembly includes a support plate horizontally arranged on one side of the clamping block and a locking rod vertically penetrated through the support plate; the upper part of the locking rod is threadedly connected to the support plate, a spring is sleeved on the locking rod, and a rotating block is provided on the upper part of the locking rod, the spring is located between the rotating block and the upper part of the support plate, and the bottom end of the locking rod is adapted to the sliding hole.
[0008] Furthermore, the grounding mechanism also includes a wiring board provided on the clamping block.
[0009] Furthermore, the warning component includes a C-shaped protective plate provided on one side of the outside of the clamping block and a displacement alarm provided on the protective plate.
[0010] Furthermore, the clamping rod is threadedly connected with a second nut located on a side of the first nut away from the clamping block.
[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0012] 1. Insert the end of the clamping rod with the hook into the bottom of the rail, and make the hook stuck on one side of the bottom of the rail. Then put the clamping block on the clamping rod so that the limit groove fits the other side of the bottom of the rail. Then rotate the fastening ring to fix the clamping rod and the clamping block on both sides of the bottom of the rail. When disassembling, just rotate the fastening ring in the opposite direction. The device can complete the installation and disassembly of the grounding mechanism by rotating the fastening ring that cooperates with the thread of the clamping rod, which improves work efficiency and reduces the problem of equipment damage or delay in maintenance progress due to improper operation.
[0013] 2. The locking rod is rotated by the rotating block so that the locking rod moves down into the sliding hole and locks the position of the sliding hole at this time to prevent the fastening ring from rotating and reduce the risk of electric shock to maintenance personnel.
