Power transmission line hoop pulley

Abstract

The invention belongs to the field of hoop pulleys. The invention especially relates to a power transmission line hoop pulley. The hoop pulley comprises a hoop body, and first threaded rods are connected to the inner side faces of the side walls of the two ends of the lower end opening of the hoop body in a penetrating mode. The surface of the middle of the first threaded rod is connected with a connecting piece in a penetrating mode. A second threaded rod is connected to a middle through hole in the side face of the lower end of the connecting piece, side plates are connected to through holesin the two sides of the second threaded rod, pin shafts are connected to through holes in the two side faces of the lower end of each side plate, pulleys are connected to middle through holes of thepin shafts, and a limiting plate is fixedly connected between the two sides of the inner wall of the middle of each side plate. According to the hoop, the hoop arms and the connecting plates are arranged, and the hoop arms are connected with the connecting plates end to end, so that the appearance structure of the hoop body forms a circular structure, the adaptability of the hoop is wider, the hoop pulley can adapt to more scenes, and the situation that the hoop cannot be fixed due to the shape problem of the hoop body is avoided.

Description

technical field [0001] The invention belongs to the field of hoop pulleys, in particular to a hoop pulley for power transmission lines. Background technique [0002] During the operation of the transmission line, due to the influence of various external factors or the aging of the line itself, various devices on the transmission line may be damaged, resulting in failure of the transmission line, and even affecting the surrounding ecology and living environment. It poses a threat to life safety, so when the transmission line fails, it needs to be repaired and replaced. [0003] In the traditional maintenance of power transmission lines, the maintenance workers usually take the components that need to be replaced to the tower, which may cause the maintenance workers to strain their lumbar muscles or cause the maintenance workers to fall from a high altitude, resulting in life-threatening, or The tool is conveyed through the transfer block, and the transfer block needs to use ...

Problems solved by technology

[0002] During the operation of the transmission line, due to the influence of various external factors or the aging of the line itself, various devices on the transmission line may be damaged, thus Cause the transmission line to fail, and even affect the surrounding ecology and living environment, posing a threat to life safety. Therefore, when the transmission line fails, it needs to be repaired and replaced

[0003]Traditionally, when repairing power transmission lines, the maintenance workers generally carry the components that need to be replaced on the tower, which may cause lumbar muscle strain of the maintenance workers Or cause maintenance workers to fall from a high altitude, resulting in life-threatening, or transport tools through the transfer block, and the transfer block needs to use endless rope sets, and the endless rope sets have various problems that are too long or too short during use. This kind of problem, its adaptability to the environment is poor, and the long-term use of the endless rope sleeve is easy to wear and tear, and the safety factor is low

[0004] discloses a transmission line hoop pulley in Chinese patent CN209963639U. Although the transmission line hoop pulley adopts the connection between the ring hoop arm and the connector way, so that the practicability of its work is improved and the safety factor is improved, but because the connection method between the hoop arm and the connecting piece needs to fix the bolt or the first threaded rod, it is more complicated for the maintenance workers working at high altitude. Temporary installation is not easy, and it is easy to accidentally cause the hoop block to fall, so it needs some improvement, and there is no corresponding limit structure on the outside of the pulley, so that the pulley and the rope may derail, causing safety hazards
