A cable ground laying device

Abstract

This application relates to a cable ground laying device, which relates to the technical field of cable laying, which includes two trolleys erected on the ground and located above the cable trench, a pay-off seat and a traction seat respectively installed on the two trolleys, and a The clamping platform on the traction seat, the two supporting platforms oppositely arranged on the pay-off seat, and the mounting columns respectively rotated on the opposite side walls of the two supporting platforms, the side walls of the clamping platform are provided with fixed grooves for cable insertion, There is a locking assembly for fixing the cable in the fixing groove, and an automatic avoidance assembly is provided on the upper surface of the traction seat to prevent the cable from contacting the side wall of the traction seat. There is a driving component on the pay-off seat to drive the rotation of the cable reel; the laying device replaces the manual dragging of the cable for laying, which saves time and effort, improves the efficiency of cable laying, and can prevent friction damage between the cable and the ground and avoid affecting the cable. power supply reliability.

Description

technical field [0001] The present application relates to the technical field of cable laying, in particular to a cable ground laying device. Background technique [0002] Cable laying refers to the process of laying and installing cables along the surveyed route to form a cable line. According to the application occasion, it can be divided into several laying methods such as overhead, underground (pipeline and direct burial), underwater, wall and tunnel. The choice of cable laying method is very important to ensure the transmission quality, reliability and construction maintenance of the line. [0003] At present, when laying cables underground, it is necessary to dig a cable trench on the ground in advance, then pour concrete on the wall of the cable trench, and then lay the cable inside the cable trench. Long, thick and hard cables, and more tortuous and complicated laying paths require more manpower to drag and limit positions. Due to the heavy weight of the cables, the...

Problems solved by technology

[0003] At present, when laying cables underground, it is necessary to dig a cable trench on the ground in advance, then pour concrete on the wall of the cable trench, and then lay the cable inside the cable trench. Long, thick and hard cables, and more tortuous and complicated laying paths require more manpower to drag and limit positions. Due to the heavy weight of the cables, the manpower and time spent on cable laying are greatly increased, and personnel are dragging When the cable is pulled, the cable and the bottom wall of the cable trench will generate a large friction force, which will easily cause the surface of the cable to be worn, resulting in damage to the outer sheath of the cable, and extrusion of the inner insulation tube. In severe cases, the insulation at the sheath will even be broken. The heat pipe will eventually affect the vacuum degree and mechanical properties of the cable system, affecting the reliability of power supply; at the same time, the friction between the cable and the ground will cause greater resistance to the movement of the cable, which greatly affects the construction efficiency of cable laying
