The cable is pulled out from the cable reel, and then the cable end is connected with a steel wire rope, the steel wire rope penetrates through the pipeline and then is connected to a winch or a tractor, and the cable is pulled out from the cable reel by using traction machinery such as the winch or the tractor and penetrates out from the outlet end of the pipeline.
the cable drags in the pipeline in the laying process, and the outer insulating layer of the cable is easy to wear due to large friction between the pipe wall and the surface layer of the cable, so that the insulating property of the cable is seriously influenced. In addition, the construction mode has the advantages of low dragging speed, low working efficiency, frequent occurrence of the problems of insufficient traction force and the like.
based on the above problems, chinese patent CN106451242B discloses a method for conveying a pipeline cable conveying device, and specifically discloses a tractor and a conveyor, wherein the tractor includes a cable rack, a hoop and a rolling support for walking, the conveyor includes a support bracket, a roller shaft, an anti-drop clamp and a rolling support, and includes a tractor in front and a plurality of conveyors in back, the front end of the tractor is connected with a traction rope, and the tractor and the conveyors are connected with each other through the traction rope. The transmission method includes the steps of placing the end part of a cable to be subjected to pipe penetration into a cable frame groove of the tractor, fixing the end part of the cable on the tractor by utilizing the hoop, placing the cable on the rear side of the tractor on a roller shaft of the conveyor, buckling the anti-falling hoop to enable the conveyor to be sleeved on the cable, and confirming that the cable is loosely matched with the roller shaft and the anti-falling hoop. The tractor is dragged by manpower or traction equipment to drive the tractor fixed at the end part of the cable and each transmitter to enter the pipeline to pass through, when the cable passes through the other end, the tractor is detached, then the transmitters are continuously dragged to move forward in a queue formed by connecting the transmitters in series, and the cables pass through the pipeline one by one.

However, the above patents have problems that: during the process of threading the cable through the duct through the tractor and the transmitter, the hoop on the tractor and the anti-slip clamp on the transmitter cause friction on the cable surface. In particular, when the retractor has been extended through the duct, the retractor cord on the retractor is pulled to extend all of the cable transport through the cable end, and during the pulling process, the cable surface will inevitably rub against the roller on the transport and the anti-slip clamp. And because there are a plurality of tractors, the roller and the anticreep clamp on each tractor can rub with the cable surface, that is to say the cable surface must experience friction many times, must cause wearing and tearing, destruction to the insulating layer on cable surface at the in-process of this friction many times, and then seriously weaken power cable's insulating properties.
