Pipeline cable conveying method

Abstract

The invention relates to a pipeline cable conveying method, and belongs to the pipeline cable field. The pipeline cable conveying method is completed by means of a cable conveying device. The cable conveying device includes a horizontal drilling machine, wherein the cable is fixedly connected with a drilling pole of the horizontal drilling machine; spiral blades sleeve and are fixed on the cable;each spiral blade includes a blade root and a blade tip which is fixedly connected with the blade root; the cross section of the blade tip is circular; the ratio between the thickness L of the blade root and the diameter of the blade tip is 1: (1-1.2); the cable is driven by the horizontal drilling machine to form a spiral pipeline cable conveying structure, and based on the structure, the spiralblades sleeve the periphery of the cable and are fixed; the cable is fixedly connected with the drilling pole of the horizontal drilling machine; the end head of the cable is arranged in the end headof the pipeline; the horizontal drilling machine is started, and the blocking particles are injected into from a feed opening above the end head of the pipeline; and during the process that the cableis conveyed to the other end head of the pipeline, the blocking particles are filled in the pipeline; and then the horizontal drilling machine is closed, and the end head, with the feed opening, of the pipeline is cut off, and then the process is completed. The pipeline cable conveying method can easily, quickly and completely convey the cable and the blocking particles to be in place synchronously.

Description

technical field [0001] The invention belongs to the technical field of pipeline cables and relates to a method for conveying pipeline cables. Background technique [0002] Due to the thick diameter and heavy weight of the pipeline cable, it is very difficult to operate the cable when it is inserted into the pipeline during the laying project of the pipeline cable. At present, the transportation of pipeline cables usually uses a large amount of manpower and large-scale mechanical traction such as winches, tractors, and tractors. The existing transportation method not only has slow dragging speed, low work efficiency, and often has problems such as insufficient traction force, but also causes damage to the inside of the cable to a certain extent due to strong mechanical pulling, and makes the cable drag in the pipeline, and the tube The friction between the wall and the surface layer of the cable is relatively large, which causes the outer insulation layer of the cable to wea...

Problems solved by technology

The existing transportation method not only has slow dragging speed, low work efficiency, and often has problems such as insufficient traction force, but also causes damage to the inside of the cable to a certain extent due to strong mechanical pulling, and makes the cable drag in the pipeline, and the tube The friction between the wall and the surface layer of the cable is large, which causes the outer insulation layer of the cable to wear and seriously affects its insulation performance

[0003] After the cable is transported, it is generally blocked and sealed by stuffing sponges, cotton sleeves, etc. into the pipeline. This kind of blocking method is time-consuming and laborious, and the blocking and sealing effects are poor, and the protective effect on the cable after filling is poor.

[0004] Therefore, it is imperative to design a safe, labor-saving and fast cable pipeline transportation method to solve the problem that pipeline cables are difficult to pass through the pipeline
