Abstract
Description
Technical Field
[0001] The utility model belongs to the field of electric power maintenance tools, and particularly relates to a vertical double-split conductor lifting clamp for lifting vertical double-split conductors. Background Technique
[0002] In recent years, the power grid construction has developed rapidly, and the high-voltage power transmission technology is widely applied. High-voltage power transmission requires the use of insulators. The high-voltage transmission line is connected and suspended on the cross arm of the tower through insulators. When the insulator reaches the service life or is damaged, the insulator needs to be replaced. When replacing the insulator of the high-voltage transmission line, the most difficult thing is how to hold the conductor conveniently and safely, ensure that the conductor is not damaged, and be able to replace the suspension insulator string in the shortest time. When replacing the insulator, it takes about 40 minutes to replace a string of suspension insulators in summer. In winter outdoor construction, the weather is cold and the natural conditions are very bad. It takes about 60 minutes to replace the insulator. Replacing the suspension insulator in winter not only wastes manpower and working hours, but also often causes employees to get injured.
[0003] Therefore, the applicant has proposed a vertical double-split conductor lifting clamp with a simple structure, convenient use, easy operation, and avoiding personal injury. This lifting clamp has the advantages of effectively improving the operation efficiency and avoiding personal injury. Summary of the Invention
[0004] The technical problem to be solved by the utility model is to provide a vertical double-split conductor lifting clamp with high operation efficiency, simple structure, and convenient operation.
[0005] To achieve the above object, the utility model provides the following technical solutions:
[0006] A vertical double-split conductor lifting clamp, including a suspension rod body 2, characterized in that: one end of the suspension rod body 2 is provided with a suspension ear 1, the suspension rod body 2 is in a rod shape, strip shape or column shape, and three hook bodies are provided on the suspension rod body 2, namely hook body A4, hook body B7 and hook body C11. The hook body A4 is provided on one side of the suspension rod body 2, and the hook body B7 and the hook body C11 are provided on the other side of the suspension rod body 2. The distance between the hook body A4 and the hook body C11 is greater than the distance between the hook body B7 and the hook body C11.
[0007] As an improvement, a protective layer is provided on the inner side of the hook body, that is, a protective layer A3 is provided on the inner side of the hook body A4; a protective layer B6 is provided on the inner side of the hook body B7; a protective layer C9 is provided on the inner side of the hook body C11.
[0008] As an improvement, a reinforcing rib is provided on the outer side of the hook body, that is, a reinforcing rib A5 is provided on the outer side of the hook body A4; a reinforcing rib B8 is provided on the outer side of the hook body B7; a reinforcing rib C10 is provided on the outer side of the hook body C11.
[0009] During actual use, the operator sits on the cantilever of the tower, fixes the hoist, hangs it on the lifting lug 1 through the hook end of the hoist, lowers the boom body 2, hooks the conductor with the hook body, and raises the hook end of the hoist to lift the conductor, facilitating the replacement of the insulator.
[0010] In practice, there are two spacings for the conductors, 40 cm and 50 cm. The spacing between the hook body A4 and the hook body C11 can be set to the standard of 50 cm, and the spacing between the hook body B7 and the hook body C11 can be set to the standard of 40 cm.
