Embodiment 1

[0032] From figure 1 It can be seen that the present invention includes a tractor and a conveyor; the tractor includes a cable rack 2, a hoop 1, and a rolling bracket for walking; the upper part of the cable rack 2 is provided with a cable groove, and multiple hoops are provided in the groove for clamping Cable; the rolling support is composed of two poles 6 with rollers 7 at the lower ends, and the upper ends of the poles 6 are fixedly connected to both sides of the cable rack 2 (or arranged at the bottom according to the situation). In this embodiment, the cable rack 2 is fixed with two groups of rolling brackets, and a hoop 1 is arranged at both ends of the cable groove.

[0033] The conveyor includes a support bracket 3, a shaft roller 4 for supporting the cable, an anti-off clamp 5 to prevent the cable from falling off, and a rolling bracket for walking; the upper part of the support bracket 3 is equipped with a plurality of horizontally arranged shaft rollers at interval...

Embodiment 2

[0050] From image 3 It can be seen that the difference between this embodiment and Embodiment 1 is that the angle A between the two poles of the rolling support is 100 degrees; Positioning, pole length can be adjusted according to the construction site conditions.

[0051] Other technical features of this embodiment are the same as those of Embodiment 1.

Abstract

The invention relates to high-voltage power cable laying, in particular to a pipe cable conveying device and a pipe cable conveying method. A high-voltage cable is high in weight and high in cable installation difficulty, the outer layer of the cable is severely worn, and the working efficiency is low. According to the technical scheme of the invention, a traction apparatus and a plurality of transmitters are connected through connecting ropes; the traction apparatus comprises a cable bracket, and a hoop fixed on the cable bracket; the transmitters comprise support brackets, shaft rollers assembled on the support brackets, and anti-drop clamps; the shaft rollers and the anti-drop clamps form a channel for allowing the cable to pass; a rolling bracket is mounted at the lower parts of the cable bracket and the support brackets. The device and method disclosed by the invention are applicable to pipe installation operation of the high-voltage power cable, the cable is pulled by the traction apparatus and supported by the transmitters for conveying, the manpower and material resources and the construction cost can be saved, and damage caused by pipe inner wall on a cable insulating layer is avoided. Moreover, damage on interior of the cable, caused by forced cable pulling of high-power machinery, is avoided, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the laying of high-voltage power cables, in particular to a pipeline cable conveying device and a conveying method. It is used for the laying project of cables in pipelines. Background technique [0002] In the pipeline laying project of electric high-voltage cables, due to the thick diameter and heavy weight of high-voltage cables (such as 10kV-500 kV cables), it usually requires a lot of manpower and large-scale operations such as winches and tractors when the cables are inserted into the pipeline. Mechanical traction: the cable is dragged in the pipeline, and the friction between the pipe wall and the cable surface is relatively large, which causes the outer insulation layer of the cable to wear and seriously affects its insulation performance. This construction method not only has slow dragging speed and low work efficiency, but also often has problems such as insufficient traction force, and the strong pulling of construc...
