Cable ground laying device

Abstract

The invention relates to a cable ground laying device. The invention relates to the technical field of cable laying. The cable ground laying device comprises two trolleys which are oppositely erectedon the ground and located above a cable trench, a pay-off base and a traction base which are installed on the two trolleys respectively, a clamping table which is arranged on the traction base, two supporting tables which are oppositely arranged on the pay-off base, and installation columns which are rotationally arranged on the opposite side walls of the two supporting tables respectively. The side wall of the clamping table is provided with a fixing groove for insertion of a cable. A locking assembly used for fixing the cable is arranged in the fixing groove. An automatic receding assembly used for preventing the cable from making contact with the side wall of the traction base is arranged on the upper surface of the traction base. The two installation columns are fixedly connected withthe two side walls of two cable reels respectively, and a driving assembly used for driving the cable reels to rotate is arranged on the pay-off base. The laying device replaces manpower to drag the cable for laying, which saves time and labor, and improves the cable laying efficiency. Friction damage between the cable and the ground can be prevented, and the power supply reliability of the cableis prevented from being affected.

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...

[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
