Problems solved by technology

When the cable is laid, the cable reel needs more people to turn it, the laying speed is uneven, and the speed of the cable reel cannot be changed in time according to the speed of the cable traction, and it consumes a lot of manpower
There is also the risk of the cable reel falling when the personnel is rotating the reel under the cable reel, causing injury to personnel and equipment
Due to the uneven speed of the turntable, when the cable traction machine is pulling, the cable often bears a large tension, which is easy to cause damage to the cable

Abstract

The invention provides a PLC control-based ultrahigh-voltage cable laying device. The PLC control-based ultrahigh-voltage cable laying device comprises a cable reel and a cable reel rack, wherein thecable reel is rotatably arranged on the cable reel rack, a PLC variable frequency conversion cabinet and at least one group of driving device are arranged on the cable reel rack, the driving device isfixedly arranged at a lower end of the cable reel on the cable reel rack and drives the cable reel to rotate, and the driving device is electrically connected with the PLC variable frequency conversion cabinet. By the PLC control-based ultrahigh-voltage cable laying device, automatic rotation control of the cable reel is achieved, the defect of rotation by employing a crane and matching of a worker is solved, and the integral laying speed of the cable is increased.

Description

technical field [0001] The invention relates to the technical field of electric power construction, in particular to a cable laying device. Background technique [0002] In the construction of step-up stations in power plants, the laying of ultra-high voltage cables has always been a difficult and risky task in electric power construction. The diameter of ultra-high voltage cables is generally more than 150mm², the diameter of the cable drum is more than 3 meters, and the weight reaches more than ten tons, so it is difficult to lay. In the past units, the laying method of high-voltage cables generally uses a crane to lift the cable reel, manually rotate the reel, and then use a tractor and a laying machine to pull the laying method. [0003] In the prior art, when laying ultra-high voltage cables, a crane is used for lifting the whole process, and the cost of the shift is relatively high. When the cable is laid, the cable reel needs more people to turn it, the laying speed...
