Description

Technical Field

[0001] The utility model relates to the technical field of insulator disassembly tools, in particular to a tool for quickly replacing high-voltage insulators. Background Art

[0002] Insulators are a special type of insulating control that plays an important role in overhead transmission lines. In the early years, insulators were mostly used on telegraph poles, and gradually developed into high-voltage power lines. Many disc-shaped insulators are hung on one end of the tower to increase the creepage distance. They are usually made of glass or ceramic.

[0003] The insulators installed on the poles need to be replaced and repaired by personnel. The tools required for maintenance include safety belts, foot buckles, transfer ropes, wire tensioners, wire clamps (swinging heads), wrenches, etc. The replacement steps are as follows: the personnel wear safety belts and use foot buckles to climb the poles. When they reach the position of the insulator to be replaced, the existing technology usually uses manual pressing of the M-shaped pin to compress it, and then laboriously pulls it out from the insulator. After pulling it out, the old insulator is passed down through the transfer rope, and then the new insulator is lifted up for installation. During installation, the large bowl head of the new insulator is first connected to the Q head on the crossarm. The connection method is to insert the Q head into the top of the large bowl head, and then squeeze the M-type pin that was pulled out before into the top of the large bowl head to connect the two. During loading and unloading, the M-type pin needs to be squeezed before it can be pulled out. There is no special tool, and manual squeezing is extremely laborious. It also needs to be shaken back and forth before it can be pulled out. This action is extremely dangerous for high-altitude operations. Moreover, there is no special tool to knock the M-type pin in when it is pressed in. It must be pressed in with fingers or knocked in with a wrench. The process is also extremely laborious, which greatly reduces the replacement speed of insulators.

[0004] Based on the above background, a tool for quickly replacing high-voltage insulators is proposed to solve the problem. Utility Model Content

[0005] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by implementing the utility model. The purpose and other advantages of the utility model can be realized and obtained through the structures specifically pointed out in the description and other drawings of the description.

[0006] The utility model aims to overcome the above-mentioned shortcomings and provide a tool for quickly replacing high-voltage insulators.

[0007] To achieve the above-mentioned purpose, the technical solution of the utility model is: a tool for quickly replacing high-voltage insulators, comprising: a handle, a connecting seat, a hammer head, a penetration rod, a rotating seat, and an M-type pin clamping assembly, wherein the connecting seat is installed on the upper side of the handle; the hammer head is fixedly arranged on one side of the connecting seat; the penetration rod is inserted into the connecting seat; the rotating seat is installed on the penetration rod; the M-type pin clamping assembly is connected to one side of the rotating seat; wherein the M-type pin clamping assembly comprises a shell, a bidirectional threaded rod, a nut ring, a clamping arm, and a sliding groove, the bidirectional threaded rod can be rotatably inserted into the shell, the two sections of the thread of the bidirectional threaded rod are threadedly connected with nut rings, the clamping arm is installed on the nut ring, and one side of the clamping arm passes through the outside of the shell through the sliding groove.

[0008] Preferably, a sealing ring is provided between the rotating seat and the penetration rod.

[0009] Preferably, the sealing ring is made of rubber.

[0010] Preferably, the sliding groove is opened on one side of the shell.

[0011] Preferably, the shell is connected to one side of the rotating seat.

[0012] Preferably, a rotating head is connected to one side of the bidirectional threaded rod passing through the shell.

[0013] Preferably, an anti-slip cover is provided on the lower side of the handle.

[0014] Preferably, a plurality of finger rings are installed on one side of the anti-slip cover.

[0015] By adopting the above technical scheme, the beneficial effect of the utility model is as follows: the utility model swings the M-pin clamping assembly, and the M-pin clamping assembly can swing at an angle on the connecting seat under the action of the penetration rod and the rotating seat. After swinging to an angle that is better for clamping the M-pin, the bidirectional threaded rod is rotated, and the bidirectional threaded rod rotates in the shell, and the nut rings on the rod approach each other, and then the clamping arm moves on the sliding groove until the M-pin is clamped, and the M-pin is squeezed and deformed, so that the M-pin can be quickly pulled out of the insulator by holding the handle. The tool can adjust the angle through the M-pin clamping assembly, and has the function of adjusting the angle to adapt to the clamping of the M-pin. The clamping arm clamps the M-pin without manual squeezing, which is more labor-saving. It is not easy to fall off after being clamped, so that the loading and unloading and replacement of the insulator are more convenient and faster, and the practicality is improved.
