A method of releasing and laying cable from cable reel

Abstract

The invention discloses a method for releasing and laying a cable from a cable reel. The method comprises the following steps: (1) hoisting the cable reel wound with the cable to a cable winding, unwinding and hoisting integrated combined vehicle; (2) a power locomotive is connected with the cable winding, unwinding and hoisting integrated combination vehicle, and the power locomotive drags the cable winding, unwinding and hoisting integrated combination vehicle to travel to the position beside a cable trench where a cable is to be laid; (3) controlling the cable take-up, pay-off and hoistingintegrated combined vehicle, releasing the cable on the cable reel, and placing the released cable beside the cable trench along the length direction of the cable trench; (4) manually laying a cable on the installation frame at the inner side part of the cable trench, and fixing the cable with the installation frame; and (5) after the cable is released from the cable reel, the cable reel is hoisted down from the cable take-up, pay-off and hoisting integrated combined vehicle, a new cable reel is replaced, and the cable continues to be laid. Time and labor are saved, the laying efficiency is improved, the cable reel can be mounted and dismounted, and other hoisting work of a construction site is met.

Description

technical field [0001] The invention relates to the technical field of cable laying, in particular to a method for releasing and laying cables from a cable reel. Background technique [0002] The cable is usually a similar rope twisted by several or groups of wires (each group has at least two wires), each wire is insulated from each other, and is often twisted around a center, and the whole is wrapped with a high degree of insulation The rubber layer, the cable has the characteristics of internal energization and external insulation. The cable is widely used in many industries such as oil fields, mines, building construction, machinery manufacturing units, scientific research units, ports, shopping malls, hotels, road and bridge construction, etc. With industry and As the needs of life become more and more diverse, the proportion of cables used will increase.

Problems solved by technology

[0003] The cables are usually coiled on the drum to form a cable reel. The cable reel is rotated and installed on a fixed bracket. When the cable is laid, the fixed bracket and the cable reel are usually moved along the cable trench by the engineering vehicle, and the cable is pulled out by people. And put the cable next to the cable trench first, or the engineering vehicle will transport the cable reel to one end of the cable trench and keep it still, manually turn the cable reel to release the cable, and another person will pull the head end of the cable along the edge of the cable trench Walk forward so that the cables are placed next to the cable trench until the other end of the cable trench. The existing cables are relatively large in size and heavy in weight. When pulling the cables, a large amount of manpower is required and the labor intensity is high; because the cables are placed in loops, Therefore, the cable has a certain degree of curvature and needs to be straightened during use, and it is difficult to straighten a long cable only by manual work, which increases the difficulty of construction. Chinese patent CN106505481A discloses a high-efficiency cable laying device. There are two transmission groups parallel to each other in the length direction of the bracket, and a cable channel is formed between the two transmission groups, so that the cable passes through the cable channel between the two transmission groups when pulled out, thereby being straightened. However, the two transmission groups The distance between the cable passages is fixed, which is only suitable for the straight laying of cables of a certain diameter, and cannot meet the straightening and laying of cables of other diameters; and the existing cable laying device has a single function, and the installation and removal of the cable reel As well as other lifting work on the construction site, only other lifting equipment can be used to complete, the cost is high, and when the construction site space is small, other lifting equipment is difficult to operate
