Description

Plug-in ground wire safety operation device

technical field

The invention relates to power transmission line maintenance equipment, in particular to a plug-in type ground wire safety operation device.

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. Most of the existing separate designs are threaded connections, which need to be rotated repeatedly during loading and unloading, and the operation is relatively cumbersome. The threaded connection is difficult to operate when docking at a long distance, which brings great trouble to the operators. Electric power workers need to keep a safe distance at all times during operation. If the accuracy of visual judgment is low, the existing equipment has a design with a scale mark on the operating rod so that the operator can judge the distance. However, in the actual operation process, due to the scale It is difficult to identify at a certain distance, and it is even more difficult to observe when the light conditions are poor. The operating rod itself has extremely high insulation requirements, and its surface is coated with special materials. If the scale mark is used, it is very likely to cause damage to the surface material and affect its normal and safe use.

The feature of the plug-in type ground wire safety operation device is that: the length of each section of coating on the surface of the rod body is 40cm.

The plug-in type grounding wire safety operation device is characterized in that: the surface of the rod body is provided with a red coating and a green coating.

In the present invention, the locking connection is adopted between the operating rod and the clamp head of the ground wire, and the docking or disengagement can be completed by one insertion and extraction during use, which is easier to operate than the screw connection. Different color intervals are used on the rod body to make it easier for operators to judge the distance.

detailed description

Embodiment one:

As shown in Figures 1 to 3, the operating rod 2 includes a rod body 21 and a joint 3 arranged on the head of the rod body. The surface of the rod body 21 is provided with a red coating 12 and a green coating 13, and the red coating 12 and the green coating 13 are arranged at intervals. The length H of each section of coating is 40cm. Three receiving grooves 5 are evenly distributed on the side of the joint 3, a limiting cavity 8 is arranged in the radial direction of the receiving groove 5, and a locking tongue 4 is arranged in the receiving groove 5. The right end surface, the rear end surface and the bottom surface of the locking tongue 4 are planes, and the rest are integrated arcs. On the surface, the limit piece 7 and the return spring 9 matching the size of the limit cavity 8, the lock tongue 4 and the limit piece 7 are connected through the slide bar 6. The lock tongue 4 protrudes outside the storage groove without external force, as shown in FIG. 2 , and retracts into the storage groove when it is squeezed by external force, as shown in FIG. 3 . A connecting pipe 10 is arranged at the bottom of the ground wire clip 1, and the connecting pipe 10 is a hollow structure, and three locking holes 11 are arranged on its side wall, and the position and size of the locking holes 11 match the locking tongue.

When hanging the ground wire, the operator pushes the operating rod joint 3 into the connecting pipe 10 at the bottom of the ground wire chuck. At this time, the lock tongue 4 in the joint 3 retracts into the storage groove 5. The tongue pops out and hangs on the lock hole, and the ground wire clip is connected with the operating rod. When the operating rod needs to be removed, turn the operating rod counterclockwise to disengage the locking tongue from the locking hole, and then remove the operating rod. The whole process is simple and fast , greatly improving work efficiency. During the operation, the operator can judge the distance by observing the red and green coatings on the operating rod. The red and green coatings are still easy to identify even in poor light environments, ensuring safe operation.

Since the right end face, the rear end face, and the bottom face of the lock tongue are flat, and the rest of the surface is an integrated arc surface, so when the joint 3 is pushed into the connecting pipe and rotates counterclockwise in the docking state, the pipe wall of the connecting pipe pushes the arc surface of the lock bolt to make the lock bolt When the bolt is retracted and the bolt is docked, since the right end face and the rear section are flat, the push, pull, and clockwise rotation of the ground wire clamp will not be affected, and the operator can easily complete the hooking of the ground wire clamp.
