Composite insulator lifting frame

Abstract

A composite insulator lifting frame is composed of a U-shaped fork, a connecting plate, a slider and a waist hook, wherein the U-shaped fork (1) is connected with the connecting plate (2), a lifting hole (5) and a slider adjusting hole (8) are formed in the connecting plate (2), the slider (11) is installed in the slider adjusting hole (8), the waist hook (6) is connected to the slider (11), a screw hole (12) is formed in the slider (11), and a locking screw (10) is arranged on the slider (11). When the composite insulator lifting frame is used, a lifting rope penetrates through the lifting hole (5) to tie the lifting frame well, the waist hook (8) is hung between two umbrella skirts of a composite insulator (14), the U-shaped fork (1) is arranged on an accessory on the end portion of the composite insulator (14) in a forking mode, and then lifting can be carried out. The composite insulator can be lifted in place by the lifting frame, installation at a high altitude can be conveniently performed, the composite insulator is protected against damage and convenient to unload and load, and the composite insulator lifting frame is safe, reliable, time-saving, labor-saving, easy to machine and low in cost.

Description

technical field [0001] The invention relates to a special tool for hoisting a composite insulator for a power transmission line, in particular to a hoisting part connected with the insulator. Background technique [0002] According to JB / T8737-1998 "Guidelines for the Use of Composite Insulators for High Voltage Lines": 7.2 When the composite insulator is hoisted, the knot should be hit on the end attachment, and it is strictly forbidden to hit the shed or sheath. The rope must touch the shed and the sheath. When removing the sheath, wrap the contact part with a soft cloth. At present, composite insulators on power transmission lines are hoisted with ropes tied to the insulators. It takes time and effort to tie the ropes and untie the ropes. Sometimes the ropes are not strong enough to cause them to fall, and sometimes the knots are tied to the end accessories due to the limitation of the pulley hanging point. The lifting will not be in place, causing difficulty in installa...

Problems solved by technology

At present, composite insulators on power transmission lines are hoisted with ropes tied to the insulators. It takes time and effort to tie the ropes and untie the ropes. Sometimes the ropes are not strong enough to cause them to fall, and sometimes the knots are tied to the end accessories due to the limitation of the pulley hanging point. The lifting will not be in place, making it difficult for people at high altitude to install. At this time, the rope can only be hit on the shed or sheath, which violates the use guidelines and causes damage to the insulator
