Secondary line laying auxiliary device capable of reducing line loss

Abstract

The invention relates to a secondary line laying auxiliary device capable of reducing line loss, which comprises a first supporting table and a middle supporting table, wherein the first supporting table and the middle supporting table respectively comprise a supporting table body, carrier rollers, a rotating roller A, a rotating roller B, a sliding seat and a horizontal telescopic jacking device,wherein the supporting table body comprises a table top and supporting legs, and brake rollers are arranged at the bottom of the supporting legs; the two carrier rollers are horizontally arranged, and the rotating roller A and the rotating roller B are both vertically arranged, opposite to each other and are located between the two carrier rollers. When the device is used, a plurality of cables are sequentially placed between the rotating roller A and the rotating roller B of the first supporting table from top to bottom, the lowest cable is in contact with the carrier rollers, and the horizontal telescopic jacking device is adjusted to enable the rotating roller A and the rotating roller B to clamp the cables. When the laying distance of the cables is long, the middle supporting table isarranged according to the actual situation. The technical scheme is simple in structure, convenient to use and capable of effectively preventing the cables from being abraded in the laying process.

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 losses. 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
