Replacing the hanging string combination tool

Abstract

The invention discloses a combination tool for changing a suspension insulator, which comprises an aluminum alloy ladder, wherein vertical rods of the aluminum alloy ladder are hollow pipes, round steels penetrate through the inside of the vertical rods of the aluminum alloy ladder, connecting plates are welded at the top ends of the round steels, adaptive bolt connection holes are arranged on the connecting plates and the vertical rods of the aluminum alloy ladder, the upper portions of the vertical rods of the aluminum alloy ladder is connected with the connecting plates through bolts. A hinged support is welded on the upper portion of one of the connecting plates, a hanging plate is connected with the hinged support in a hinged mode, an inserting hole is arranged at the end of the hanging plate, a plug pin which has pin holes and blocking rings and is adaptive to the inserting hole is arranged on the upper portion of the other of the connecting plates, a pin is arranged on each of the pin holes, a hanging ring is welded at the lower end of one of the round steels, a first hanging hook is connected with the hanging ring, an adjusting ring is welded on the lower end portion of the other of the round steels and is connected with an adjusting lead screw, and a second hanging hook is connected with the adjusting lead screw. The combination tool for changing the suspension insulator is convenient and safe to use and labor-saving.

Description

technical field [0001] The invention relates to an electrical tool, in particular to a combined tool for replacing hanging strings. Background technique [0002] As we all know, insulators need to be replaced when their service life reaches the operating limit or they suffer from lightning strikes and other damages. Insulators are divided into: tension insulators, linear insulators and hanging strings according to their uses. Since the hanging strings are completely suspended in the air, there is no focus Therefore, the work of changing the hanging string becomes particularly complicated and difficult. At present, when replacing the hanging strings, workers first need to use a ladder to get down from the cross arm to the shoulder pole, and then use several lead wire sleeves and double hooks to connect, lift the shoulder pole to separate the hanging strings, and replace them. Its disadvantages are: in addition to the climbing ladder, a double hook and 3-5 lead wire sleeves a...

AI Technical Summary

Problems solved by technology

Its disadvantages are: in addition to the climbing ladder, a double hook and 3-5 lead wire sleeves are usually connected between the cross arm and the shoulder pole. There are many connecting tools and complicated procedures. In addition, the working space on the pole tower is very small, and the operation is very inconvenient; , since the lifting device has only one force point, after the double hooks are tightened, the shoulder pole clamp will be deflected, the spring pin will be easily stuck, and it is very difficult to take it out

It often requires another operator to cooperate on the cross arm to complete the work; third, because the shoulder pole is always under a single point of force, the operator is like standing on a seesaw in the whole operation process, which brings great pressure to the operator. Inconvenient operation and unsafe factors
