A wire tightening device for electric installation

Abstract

The invention discloses a wire-tightening device for electric power installation. The device comprises a base. Two side plates are fixedly installed on the base. A bearing is fixedly embedded in the side plates. A driving shaft is interference-fit in the bearing. A motor is fixedly installed on each side plate. The rotating shaft of the motor and the driving shaft are fixedly installed through a coupler. A winding drum is fixedly installed on the driving shaft, cables are wound on the winding drum, a gear is fixedly installed on the driving shaft, a first cylinder is fixedly installed on the base, and clamping teeth are fixedly installed on the piston rod of the first cylinder and the clamping teeth are meshed and connected with the gear. The cables can be released or tightened through thewinding drum. After the driving shaft is rotated and positioned, the clamping teeth can be matched with the gear to mesh so as to realize the clamping stability of the driving shaft, ensure that thecables can be tightened during construction and lift the cables from the bracket through the wire base, thus preventing workers from climbing in the bracket and reducing the occurrence of safety accidents.

Description

technical field [0001] The invention relates to the technical field of electric installation, in particular to a wire tightening device for electric installation. Background technique [0002] Power installation refers to the project of undertaking (repairing and testing) power facilities. Power installation companies have different levels. High-level power installation companies can build and install power plants, large substations, and high-voltage transmission lines. [0003] At present, most electric power companies still serve urban electric power projects, and urban electric power projects need to install cables in places where pedestrians often travel. The common way is to erect cables in the air so that people cannot touch them at will. . [0004] When the cable is prepared, it will be wound and reeled with a bobbin, which is convenient to move. When it is released, it can be pulled out directly. However, due to the construction in the air, if the cable has a large ...

AI Technical Summary

Problems solved by technology

[0004] When the cable is prepared, it will be wound and reeled with a bobbin, which is convenient to move. When it is released, it can be pulled out directly. However, due to the construction in the air, if the cable has a large diameter, it is easy to hang down. , it is inconvenient to tighten the cable, resulting in the unstable installation of the cable

[0005] Moreover, when the cable is installed, if part of the position is high, the height of the manual bracket is not enough, and the workers need to climb the bracket cable, which is time-consuming and laborious, and is likely to cause safety accidents.
