A secondary line laying auxiliary device for reducing line loss

Abstract

The invention relates to a secondary line laying auxiliary device for reducing line loss, comprising a first support platform and an intermediate support platform, both of which include a support platform body, idler rollers, a rotating roller A, a rotating roller B. Sliding seat and horizontal telescopic jacking device; the support platform body includes a table top and outriggers, and brake rollers are provided at the bottom of the outriggers; the two supporting rollers are set horizontally, and the turning roller A and turning roller B are both vertically set and opposite to each other. Setting, located between two rollers; when in use, place multiple cables from top to bottom between the rotating roller A and rotating roller B of the first support table, the lowest cable contacting the roller, adjust The horizontal telescopic clamping device enables the rotating roller A and the rotating roller B to clamp the cable; when the laying distance of the cable is long, the intermediate support platform is arranged according to the actual situation; this technical scheme is simple in structure, easy to use, and effectively prevents Abrasion of the cable wires.

Description

technical field [0001] The invention relates to the technical field of electric power construction auxiliary facilities, in particular to an auxiliary device for laying secondary lines that reduces line loss. Background technique [0002] When laying secondary cables in new substations, the cables are usually directly dragged on the ground for construction. If there is no suitable auxiliary laying device, the corner civil foundation of the substation will be worn during the dragging process, and the cable itself will also be damaged. The insulation skin wears out, which not only affects the construction quality of the new substation, but also brings safety hazards to the substation after it is put into operation.

[0002] When laying secondary cables in new substations, the cables are usually directly dragged on the ground for construction. If there is no suitable auxiliary laying device, the corner civil foundation of the substation will be worn during the dragging process, and the cable itself will also be damaged. The insulation skin wears out, which not only affects the construction quality of the new substation, but also brings safety hazards to the substation after it is put into operation

[0003] The Chinese invention patent with the publication number CN104882829B discloses a cleaning and protection device for secondary cable laying in a substation, including a mounting frame and a clamping cleaner. Fixed connection, this technical solution has the following disadvantages: 1) The structure of the mounting frame is not suitable for use at the protruding corners of two vertically intersecting walls, and it cannot be fixed relative to the wall; 2) When the secondary cable passes through the clamping cleaner, it needs to Pass through one by one. If multiple such protective devices are used in the project construction, the threading process must be in sequence. If one more protective device is added in the middle, it will be very cumbersome and inefficient; 3) This kind of bracket It can only prevent the cable from wearing the wall when the installation conditions permit, but it cannot avoid the friction between the cable and the ground during the dragging process, resulting in the abrasion of the cable sheath
