Clamp for replacing glass insulator for power transmission line

Abstract

The invention discloses a clamp for replacing a glass insulator for a power transmission line. The clamp is provided with two hooks and is characterized in that the hooks are of a hollow spindle shape; a fastening bolt is arranged on one side of each hook; connecting plates are respectively arranged at two ends of each hook; a connecting hole is formed in each connecting plate; a thread bush is arranged in each connecting hole; and a screw rod is arranged between every two corresponding thread bushes. Compared with a chain block, the clamp disclosed by the invention has the advantages of no cumbrous chains, light quality and convenience in carrying. The hooks which are of the hollow spindle shape are arranged and matched with a nut of the glass insulator, so that when the clamp is in use, the nut of the glass insulator is sleeved by the hooks; the nut of the glass insulator can be locked by rotating the hooks without slipping off; the steps are simple; and the labor intensity of workers is reduced. The two hooks are tightened by adopting the screw rods, so that the work can be finished by one worker and the labor force is further saved; and the operation can be finished without the matching of two persons at one time, and thus the work efficiency is greatly increased.

Description

technical field [0001] The invention relates to a jig for replacing glass insulators of transmission lines used in circuit maintenance operations. Background technique [0002] Glass insulators may self-explode during use, and glass insulators that have self-explosion must be replaced in time. At present, the way to replace the glass insulator is: use two chain hoists to hook the nuts of the two glass insulators, and pull towards the middle to remove the glass insulator. [0003] The disadvantages of this method of replacing glass insulators are: [0004] 1. Due to the large mass of the chain hoist and the long chain, it is not easy to carry. [0005] 2. Because the hook at the front end of the chain hoist does not match the nut of the glass insulator, it takes time and effort to hook it, and the hook often falls off, duplicating the work, and the labor intensity of the staff is high. [0006] 3. When replacing, two people need to pull the chain hoist to the middle at the...

Problems solved by technology

[0004] 1. Due to the large mass of the chain hoist and the long chain, it is not easy to carry

[0005] 2. Because the hook at the front end of the chain hoist does not match the nut of the glass insulator, it takes time and effort to hook it, and the hook often falls off, repeating the work, and the labor intensity of the staff is high

[0006] 3. When replacing, two people need to pull the chain hoist to the middle at the same time, which wastes manpower, and it is difficult for two people to cooperate, and the work efficiency is low
