Description

Lifting hook, high-altitude lifting hoist and tightener

Technical Field

The utility model relates to a lifting hook, high altitude hoist and turn-buckle.

Background

The current power supply line is still mainly an overhead line, so most of newly-added projects, reconstruction projects and emergency repair projects are all pole overhead operations. Some of the pole-mounted operations involve replacing equipment, such as transformers, circuit breakers and other large and heavy equipment, which cannot be transferred up and down by using common ropes, and the equipment needs to be lifted by using an overhead lifting hoist. In addition, turnbuckles are also frequently used in overhead line operations. The hoisting hoist and the tightener are both provided with lifting hooks, the lifting hook of the hoisting hoist is a main stress point in the whole process, bears the whole weight of the hoisting and is a first stress point in the hoisting process, so the stability of the lifting hook needs to be ensured, however, the existing lifting hook lacks an anti-drop device, and during the high-altitude hoisting process, the lifting hook sometimes slides out, so that heavy objects fall to the ground, and personal and property loss is caused; the lifting hook of turn-buckle front end is used for hooking the wire, but the anticreep device that current turn-buckle's lifting hook used only a little iron sheet (as shown in fig. 1), often damages, causes the wire to slide very easily.
