A kind of steering pulley for tension wire protection wire marking

Abstract

The invention discloses a wire protection marker steering tackle for tension stringing, which belongs to the field of electric tools. A kind of steering tackle for tension stringing with guard wire marking, comprising a tackle body with a hook and a cross bar, an audible and visual alarm is fixedly connected to the outer side of the tackle body, and a wide pulley is arranged inside the tackle body. A generator is installed at one end inside the block body, one end of the wide pulley is connected to the generator, the other end of the wide pulley is connected to the block body in rotation, a wire is wound on the wide pulley, and a protective wire is used for tensioning the wire. The marking steering block also includes a speed sensor, and the speed sensor measures the rotational speed of the wide pulley, and both sides of the wide pulley are provided with a wire protection mechanism, and the wire protection mechanism includes a collar and a first elastic telescopic rod, and the sleeve The loop fits over the end of the wide pulley. It can further improve the pay-off quality through better control of the speed during the tension stringing process, and can mark the place where the wire is worn at the pulley for easy inspection.

Description

technical field [0001] The present invention relates to the field of electric tools, and more particularly, to a steering pulley for tension wire protection wire marking. Background technique [0002] Tension set-up is to lay out the wire by means of tension pay-off. The wire is always in an overhead state during the entire pay-off process to avoid friction between the wire and the ground. [0003] Tension wire has many advantages: good pay-off quality; good degree of mechanization; fast pay-off speed and high efficiency. [0004] The key point of the quality of the tension wire is to control the protection of the wire in each link of the wire. The anchoring, loosening, tightening and other operations in the process of high-altitude wire should not be moved too fast or too fast, resulting in the movement of the wire. Unstable, when the wire slides on the high-speed steering pulley, the runaway wire will be damaged by friction with the side of the high-speed steering pulley...

Problems solved by technology

[0009] ①Slight loss exceeding 8.5% of the rated calculated breaking force;

[0015] In the prior art, the tension stringing is fixed with a pulley structure, which cannot protect the wires, and after the tension stringing is completed, the construction personnel have a huge workload to check the wires, which is very inconvenient, and it is difficult to analyze the cause of wire damage
