Cord support devices for protection against wear and tear for power transmission

Abstract

The invention discloses a rope support device for preventing wear and tear in the field of power transmission, which includes a base and a power transmission tower fixedly connected to the upper end of the base, a device cavity is opened in the side wall of the base, and a cavity is opened in the side wall of the power transmission tower. The device cavity is slidingly connected with a horizontal plate relative to the inner wall. The upper end of the horizontal plate is fixedly connected with a forward and reverse motor. The lower end of the horizontal plate is fixedly connected to the bottom of the device cavity through an electric push rod. The output shaft of the forward and reverse motor The coaxial fixed connection has the main gear. In the present invention, by setting a rope winding mechanism, a fixing mechanism, a clutch mechanism, a locking mechanism and a plurality of driving mechanisms, the rope can be routed from two fixed pulleys without contact and friction with the transmission tower or the base, effectively preventing the rope from In the event of wear and tear, the automatic lifting of the rope and the automatic lifting of the heavy object can be realized at the same time, without manual operation, which not only reduces labor costs, but also avoids danger.

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...

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 ropes and the bottom components is too large, it is easy to wear the insulating ropes during the lifting process, resulting in It is scrapped, resulting in greater economic losses and increased maintenance costs

[0004] At the same time, the existing lifting process is usually driven by manpower. This lifting method not only has high labor intensity, but also has the danger of heavy objects falling during the actual lifting process, which is easy to injure the staff and has a certain degree of danger.
