Abstract

A separate ground wire device that is easy to assemble and disassemble, including a ground wire clip and an operating rod. The bottom of the ground clamp and the tail of the operating rod are provided with threaded holes matching the connector, the opening of the threaded hole at the bottom of the ground clamp is provided with an umbrella skirt, and the tail of the operating rod is provided to match the connector The threaded hole and the outer pin hole matching the inner pin hole. In the present invention, the ground wire chuck and the operating rod, and between the operating rod and the operating rod are all detachable structures, which greatly increase the convenience of carrying. The stability of the connection between them makes the disassembly of the ground clamp more convenient and safe. The ground wire clip is equipped with an umbrella skirt, so that the operator can easily align and complete the connection between the ground wire clip and the operating rod at a relatively long distance.

Description

A separate ground wire device that is easy to assemble and disassemble

technical field

The invention relates to power transmission line maintenance equipment, in particular to a separate ground wire device which is easy to assemble and disassemble.

Background technique

When electric workers inspect or repair high-voltage lines, they need to carry grounding wire equipment to perform grounding operations on the three-phase circuits respectively to ensure safety during operation. The traditional ground wire equipment ground wire chuck and operating rod are designed in one piece, which is bulky and heavy, which is very unfavorable for operators to climb and operate. However, the operating levers of the existing separate design simply design some detachable structures or telescopic structures, only to make it easy to carry, but in actual operation, due to the instability of the connecting structure between the operating levers or the telescopic structure of the operating levers, It is extremely inconvenient to disassemble the ground wire clip. When the operator completes the operation and removes the ground wire clamp, he needs to connect the operating rod to the ground wire clamp again. At this time, because the operator is far away from the ground wire clamp, it is difficult to align when connecting, and the operation is difficult.

Contents of the invention

Aiming at the deficiencies of the prior art, the present invention provides a separate ground wire device that is easy to carry, difficult to misuse and easy to disassemble.

The technical solution adopted by the present invention is: a separate grounding wire device that is easy to assemble and disassemble, including a ground wire chuck and an operating rod, and is characterized in that: the operating rod includes a rod body and a connecting head arranged at the head of the rod body, The connector is provided with threads and radial inner pin holes, the bottom of the ground clamp and the tail of the operating rod are provided with threaded holes matching the connector, the opening of the threaded hole at the bottom of the ground clamp is provided with an umbrella skirt, the A threaded hole matched with the connecting head and an outer pin hole matched with the inner pin hole are arranged at the end of the operating rod.

The separate ground wire device is characterized in that: the length of the operating rod body is 40cm.

In the present invention, the ground wire chuck and the operating rod, and between the operating rod and the operating rod are all detachable structures, which greatly increase the convenience of carrying. The stability of the connection between them makes the disassembly of the ground clamp more convenient and safe. The ground wire clip is equipped with an umbrella skirt, so that the operator can easily align and complete the connection between the ground wire clip and the operating rod at a relatively long distance.

detailed description

As shown in Figures 1 and 2, the operating rod 2 includes a cylindrical rod body 21, the length of which is 40 cm. 1 The bottom of the right side and the bottom of the rod body 21 are provided with a threaded hole 4, the threaded hole 4 is matched with the connector 3, an umbrella skirt 8 is provided at the opening of the threaded hole at the bottom of the ground clamp 1, and an external pin hole 5 is provided at the threaded hole at the bottom of the rod body 21, and the external pin hole The size of the position matches with the inner pin hole 6.

When the operating rod is connected or removed from the ground clip, it is only necessary to align the connecting head on the top of the rod body with the threaded hole and rotate it to install or remove it. After the work is completed, use the operating lever to connect the ground wire chuck again. Due to the long distance, the connector is not easy to align with the threaded hole. First, align the connector with the larger opening of the shed, and then the docking can be easily completed after entering the shed. As shown in Figures 2 and 3, when connecting the operating rods, first align the connecting head with the threaded hole of the previous operating rod and rotate it, tighten it and align it with the inner and outer pin holes, and insert the fixing pin 7 to fix it. At this time, when rotating When the operating rod is loaded and unloaded with the ground wire chuck, the connection between the operating rods will not be affected in any way, which greatly increases the convenience and safety of the operation. Setting the rod body of the operating rod to 40cm can make it easier for the operator to judge the safe distance.
