A pipeline cable conveying method with an auxiliary support structure

Abstract

The invention provides a pipeline cable conveying method with an auxiliary supporting structure and belongs to the technical field of pipeline cables. The pipeline cable conveying method is completedby means of a cable conveying device, the cable conveying device comprises a horizontal drilling machine, a cable is fixedly connected with a drilling rod of the horizontal drilling machine, and the cable is fixedly sleeved with spiral blades. The spiral blades comprise blade roots and blade tips fixedly connected with the blade roots, the cross sections of the blade tips are circular, and the ratio of the thickness L of the blade roots to the diameter D of the blade tips is 1:(1-1.2). A spiral pipeline cable conveying structure is formed through the cable by means of driving of the horizontaldrilling machine and further comprises a supporting frame provided with a travelling mechanism and arranged between the drilling rod and a pipeline and a cable groove formed in the supporting frame,and a shaft roller for bearing the cable is arranged in the cable groove. On the basis of the spiral pipeline cable conveying structure, in the process that the cable is spirally conveyed to the otherend of the pipeline by means of the horizontal drilling machine, the pipeline is filled with plugging particles finally. According to the pipeline cable conveying method, the cable and the plugging particles can be easily, rapidly, and synchronously conveyed in place in good condition.

Description

technical field [0001] The invention belongs to the technical field of pipeline cables and relates to a method for conveying pipeline cables with an auxiliary support structure. 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 ...

AI Technical Summary

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
