Problems solved by technology

[0003] In the lifting process at noon, the existing technology usually uses insulated ropes as lifting tools, especially in live work. During the operation, the operator generally uses the bottom member of the transmission tower as a fulcrum for controlling the rope during the lifting process. , in order to achieve the purpose of lifting heavy objects, but because the bottom components of transmission towers are generally made of hard and rough materials, and the friction coefficient between the r

Abstract

The invention discloses a wear-resistant rope supporting device special for power transmission. The device comprises a base and a power transmission rod tower fixedly connected to the upper end of thebase, a device cavity is formed in the side wall of the base, a cavity is formed in the side wall of the power transmission rod tower, a transverse plate is slidably connected to the opposite inner wall of the device cavity, the upper end of the transverse plate is fixedly connected with a forward and reverse rotating motor, the lower end of the transverse plate is fixedly connected to the innerbottom of the device cavity through an electric push rod, and a main gear is coaxially and fixedly connected to an output shaft of the forward and reverse rotating motor. By arranging a rope winding mechanism, a fixing mechanism, a clutch mechanism, a locking mechanism and multiple driving mechanisms, ropes can be routed from the two fixed pulleys without contact friction with the power transmission rod tower or the base, abrasion of the ropes is effectively prevented, automatic lifting of the ropes and automatic hoisting of heavy objects can be realized, manual operation is not needed, the labor cost is reduced, and danger is avoided.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a rope support device for preventing abrasion in the field of power transmission. Background technique [0002] In the operation, maintenance and repair of overhead transmission lines, due to the high height of the transmission tower, the staff cannot carry more maintenance tools to climb to the top, so it is often necessary to use insulated ropes to lift heavy objects such as maintenance tools to the top of the tower to facilitate the operation of the staff. [0003] In the lifting process at noon, the existing technology usually uses insulated ropes as lifting tools, especially in live work. During the operation, the operator generally uses the bottom member of the transmission tower as a fulcrum for controlling the rope during the lifting process. , in order to achieve the purpose of lifting heavy objects, but because the bottom components of transmission towers ar...
