Description

Cable laying device for electrical automation control

Technical Field

The invention belongs to the technical field of cable laying equipment, and particularly relates to a cable laying device for electrical automation control.

Background

At present, electric power is an energy source using electric energy as power. In the 70's of the 19 th century, the invention and application of electric power started the second industrialized climax. The method becomes one of three scientific and technological revolution which occur in the world since the 18 th century of human history, and changes the lives of people from now on. The large-scale power system appearing in the 20 th century is one of the most important achievements in the history of human engineering science, and is a power system consisting of links of power generation, power transmission, power transformation, power distribution, power utilization and the like. In the whole power system, the cable is used as a wire product for transmitting electric energy, and the generated electric energy can be transmitted to each user. With the continuous development of the society, in order to enable more people to use better and more efficient electric energy, the range of the electric power system needs to be continuously increased and cables in the electric power system need to be replaced in time, so that dangerous accidents caused by aging of the cables are avoided, and the cables need to be laid by operators.

Conventional cable laying refers to the process of laying and installing cables along an investigated route to form a cable run. At present, in order to improve the efficiency of cable laying, cables are generally fixed while being led out from a cable roll, so that the time for laying the cables by operators can be reduced, and the efficiency of cable laying is improved. However, in the operation process, the cable is often rotated to cause knotting, so that the cable is screwed to increase the pressure between a plurality of internal conducting wires, the heating value of the cable is increased, the aging of the cable is accelerated, and dangerous accidents caused by heating are easy to occur, so that an operator needs to take great care when the cable is led out from a cable roll. The cable self-screwing device is obtained through a large amount of research and analysis on a cable laying field, the reason for the cable self-screwing is that when the existing cable is produced, the cable is wound on a cable drum step by step, and in order to avoid the cable on the cable drum from loosening, larger pressure is used when the cable is wound, so that adjacent cables are tightly attached together. And operating personnel can make the cable move from right to left or from left to right when progressively drawing forth the cable, draws forth the certain contained angle of cable and the not unclamped cable in side this moment, and the cable that does not unclamp has ascending effort to drawing forth the cable to the cable that does not unclamp can expand, has a side effort to drawing forth the cable, finally leads to drawing forth the cable and takes place the condition of rotatory screwing up. At present, when the cable is laid and is twisted in a rotating mode, operators rotate reversely to loosen the cable tightening part when the cable is screwed lightly, and then the cable can be laid continuously; when the condition of knoing is more serious, operating personnel can only be here after the disconnection cable, again with the cable reconnection after releasing the tip of cable, not only increase the work load of cable laying, dangerous accident also takes place easily in cable joint department moreover, leads to greatly reduced the efficiency and the quality of laying of cable.
