A support device and a wire-laying method for power cables

Abstract

The invention belongs to the technical field of an electric power facility construction tool and especially relates to a support device for power cable paying off and a paying off method. The support device comprises a support and a cable roll shaft. The support comprises a cross beam, channel steel stop heads, positioning columns and lifting lugs. The channel steel stop heads, the positioning columns and the lifting lugs are arranged symmetrically from the ends to the center of the cross beam in sequence. The cable roll shaft comprises a core shaft. The two ends of the core shaft are respectively provided with a circular stop head. Fixing sleeves are symmetrically arranged on the core shaft. Each fixing sleeve is provided with a top thread. The support is connected with the cable roll shaft through a steel rope. The invention also discloses a method, which is characterized in that one end of a cable drops down naturally from a roller; an excavator is driven to drive slowly in a reverse direction along cable paying off places; two persons at the two sides of the roller controls the rotation speed of the roller according to the driving speed of the excavator to enable the cable to land stably without any dragging phenomenon; and one person specially takes charge of the cables on the ground. The beneficial effects are that labor intensity of constructors is saved greatly; manpower is saved; time is saved; cost is low; structure is simple; and installation can be done conveniently.

[0002] When carrying out development and construction on barren hills, wasteland and rough roads, some large electrical equipment is often used, such as winches, mixers, crushers, etc. At this time, sheathed power cables must be erected, and the cables are strictly prohibited from colliding during laying construction. and friction with the ground, due to the restrictions on the construction site, such as no roads or vehicles that cannot drive, in this environment, in the process of laying existing cables, manual laying has been used, especially for laying very large cables. Above 10kg, because the cable is not allowed to rub directly with the ground, it is afraid of causing damage to the outer insulation layer, so it must be carried by hand or shoulder. Because the weight is too heavy, at least 30 people are required to drag it for every 100 meters. The longer the number, the more people are employed, so that the cable will not drag the floor. This process causes the construction personnel to be labor-intensive, labor-intensive, inefficient and easily cause damage to the cable.
