New material power cable tension control device utilizing pulley block principle

Abstract

The invention relates to the technical field of electric power, and discloses a new material power cable tension control device utilizing a pulley block principle. The new material power cable tensioncontrol device comprises a shell, a fixed pulley is arranged in the shell, a rotating wheel is arranged in the shell, a first movable pulley is arranged on the surface of the rotating wheel, and a push column is arranged on the surface of the rotating wheel; and a second movable pulley is arranged in the shell, a push plate is arranged on the surface of the second movable pulley, a driving pulleyis arranged in the shell, and a sliding seat is arranged on the surface of the driving pulley. According to the new material power cable tension control device utilizing the pulley block principle, the fixed pulley and the first movable pulley are used in cooperation, the first movable pulley and the second movable pulley are used in cooperation, and the second movable pulley and a driving pulleyare used in cooperation, so that multi-stage adjustment of the length of a cable is achieved, meanwhile, resistance during adjustment is reduced, the effect of adjusting the length of the cable is effectively improved, the use safety of the cable is guaranteed, and the service life of the cable is prolonged.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a new material power cable tension control device utilizing the pulley block principle. Background technique [0002] Cable is one of the important media for power transmission. The quality of the cable directly determines the effect of the power transmission. In order to improve the effect of cable transmission, increase the safety of the cable, and prolong the service life of the cable, the cable will be in the main part of the cable during production. Some new materials with this characteristic are added to the raw material, so that the cable has relevant characteristics. [0003] When the cable is installed, due to the characteristics of thermal expansion and cold contraction of the cable, the surface of the cable will expand during the relatively hot period, resulting in an increase in the length of the cable, and the installed cable will sag. In order to reduce the...
