Problems solved by technology

[0002] At present, in the process of power distribution construction, it is necessary to lift various power distribution parts to the top of the utility pole. If the weight of the parts is heavy, a crane is used for hoisting. If the weight of the parts is light, There is no special lifting device for lifting, so construction workers have to directly lift the spare parts up with a sling on the top of the utility pole. When lifting, they need to bend down to lift the sling, thus greatly reducing the safety of construction. , due to the large tension required when lifting the sling, it is easy to cause fatigue and reduce the work efficiency of power distribution work

Abstract

The invention discloses a portable lifting device for power distribution construction, which comprises a left collar and a right collar. A fixed block, a fixed bolt is arranged between the left fixed block and the right fixed block, a lifting frame is fixed on one side of the left collar, a first rotating shaft and a second rotating shaft are arranged on the lifting frame, and the first gear is fixed on the first rotating shaft , the second shaft is provided with a second gear, the first gear meshes with the second gear, a ratchet and a reel are fixed on the second shaft, a sling is wound on the reel, and a sling is connected to the end of the sling hook up. The beneficial effects obtained by the present invention are: (1) simple structure; (2) high safety performance, and the required torque for shaking the handle is small, which is very labor-saving; (3) has a locking function, which can prevent hooks and power distribution parts from It moves downwards under the force of gravity, further increasing the safety of lifting work.

Description

technical field [0001] The invention relates to a power distribution auxiliary tool, in particular to a portable lifting device for power distribution construction. Background technique [0002] At present, in the process of power distribution construction, it is necessary to lift various power distribution parts to the top of the utility pole. If the weight of the parts is heavy, a crane is used for hoisting. There is no special lifting device for lifting, so the construction workers have to directly lift the spare parts up with a sling on the top of the utility pole. When lifting, they need to bend down to lift the sling, thus greatly reducing the safety of the construction. , due to the large pulling force required when lifting the sling, it is easy to cause fatigue and reduce the work efficiency of the power distribution work. Contents of the invention [0003] The problem to be solved by the present invention is to provide a portable lifting device for power distribu...
