Embodiment Construction

[0031] The present invention will be further described below in conjunction with accompanying drawing.

[0032] The auxiliary device for the linear pole of the shared corridor for electrified migration of the present invention is used to migrate the linear pole of the common line corridor. The linear pole is provided with a straight cross arm, and insulators are arranged at both ends of the straight cross arm. The straight cross arm is usually an angle steel, including mutual Vertical horizontal section and vertical section.

[0033] Such as figure 1 As shown, the auxiliary device includes a crossbeam 1, one end of the crossbeam is provided with a linear crossarm clamping part 2, and the other end of the crossbeam is fixed with a wire fixing device 3;

[0034] Such as figure 2 As shown, the clamping part of the straight cross arm is C-shaped, including horizontal plate I4, horizontal plate II5 and vertical plate 6, horizontal plate I and horizontal plate II are parallel, on...

Abstract

The invention relates to the field of an overhead mounting device of a line or a cable, and particularly to an auxiliary device of a live migration common corridor linear rod. The auxiliary device comprises a crossbeam. One end of the crossbeam is provided with a linear cross arm snapping part. The linear cross arm snapping part is C-shaped and comprises a horizontal plate I, a horizontal plate IIand a vertical plate. The other end of the crossbeam is provided with a lead fixing device which is fixed. The lead fixing device comprises a fixing column I, a fixing column II and an automatic locking board. The auxiliary device according to the invention matches an original linear rod pole and can move the lead in the horizontal direction, thereby supplying a sufficient space for mounting of anew pole and detachment of an old pole, and realizing electric pole changing operation on the condition of incapability of hoisting the lead. The auxiliary device according to the invention does notrequire a crane or a hoisting vehicle for hoisting the lead, thereby preventing dangers in a lead hoisting process, and realizing higher safety and higher efficiency of the operation method.

Description

technical field [0001] The invention relates to the field of overhead installation devices for electric wires or cables, in particular to an auxiliary device for a linear rod in a shared corridor with electromigration. Background technique [0002] Line corridor refers to the land area and spatial area occupied by the path of overhead transmission lines. [0003] In order to ensure the insulation strength of the line and avoid the danger of electric shock to people, ground buildings and other objects, as well as to prevent the electrostatic field from causing physiological and ecological hazards to the wires and nearby people, it is necessary to maintain a necessary clear space around the wires under high voltage. . High-voltage overhead transmission lines will generate an induced electrostatic field on the surface of the earth. In order to weaken the intensity of this electrostatic induced electric field to the extent that it will not endanger personal safety, the conducto...
