Cable laying mechanism in power construction

Abstract

The invention belongs to the technical field of cable laying, and particularly relates to a cable laying mechanism in power construction, which comprises a winding roller and a cable penetrating pipe; when a cable is laid, the laying mechanism is placed in a well dug in advance; a guide mechanism is mounted on the cable from the upper side; a person does not need to stand in a well to operate, so that the labor intensity is relatively low; and meanwhile, the laying mechanism is placed in the well, the occupied road surface is relatively small in the construction process, and the situation that the road surface traffic is affected due to the fact that construction equipment occupies the road surface can be prevented to a certain extent. The guiding mechanism is erected on the inner side of the cable penetrating pipe through three supporting mechanisms which are evenly distributed in the circumferential direction; due to the fact that the cable penetrating pipes of different models are different in thickness, and guide wheels of different models and sizes are also different, the guide mechanisms of different models and sizes adapt to different cable penetrating pipes through the length-adjustable supporting rod, and the cable penetrating pipes of various sizes are met by replacing the models of the guide mechanisms and adjusting the length-adjustable supporting rod.

Description

technical field [0001] The invention belongs to the technical field of cable laying, in particular to a cable laying mechanism in electric power construction. Background technique [0002] When installing cables now, the cables are usually buried underground. On the one hand, it can enhance the reliability of the urban power grid. Because the cables are exposed in the air, exposed to wind and rain, it is easy to cause cable aging and insulation layer to fall off. It is easily corroded by acid-base gas and water vapor in the atmosphere, so overhead cables have many hidden dangers. On the other hand, it can enhance the transmission capacity of the city. The cable lines buried underground can reach many loops. The underground high-voltage cables generally have copper conductors with higher efficiency, so that they can transmit electric energy efficiently. At the same time, the method of burying the ground can better reduce dangerous accidents and avoid personal safety accident...

AI Technical Summary

Problems solved by technology

During the construction, multiple pipelines are often laid to facilitate the penetration of new cables in the future; during the penetration process, due to the long cable tube, the friction resistance during the penetration process is relatively large, and it is difficult to penetrate; if the cable A guide wheel is added on the outside to guide in the pipe to reduce frictional resistance, but the guide wheel cannot be removed after installation, resulting in increased costs; and after the cable is threaded, each pipe opening needs to be sealed, and the seal requires an additional process to operate. When there is heavy rain, poor sealing of the pipe opening will cause muddy water to enter the pipe, causing cable corrosion and conductive pad failure

[0004] In addition, when laying new pipes now, various construction equipment on the road take up a lot of space, especially the laying mechanism, which seriously affects the traffic during construction
