AI Technical Summary

Problems solved by technology

The sag generated by the protection rope is too large, which reduces the safe distance between the wire and the protection rope, and the discharge of the wire to the protection rope is prone to occur, thus causing electric shock accidents to the workers

Embodiment 2

[0043] Such as image 3 As shown, the same parts as those in Embodiment 1 will not be repeated, and the differences include: the connecting plate 7 is hinged with the rigid casing 4; the pulley includes left and right sliders 11, and left and right sliders 11 Splicing forms a rope hole in the middle; rolling elements evenly arranged in the circumferential direction are arranged in the rope hole; Bearing-type rope holes are used to facilitate the passage of ropes.

[0044] above Figure 1-3 The shown large height difference and large span line live working rope fixing device and its working method are specific embodiments of the present invention, which have already reflected the substantive features and progress of the present invention, and can be based on the actual use needs in the enlightenment of the present invention Under the circumstances, the equivalent modification of its shape, structure and other aspects are all within the scope of protection of this scheme.

Abstract

The invention discloses a large-altitude difference and large-span circuit hot-line work rope fixing device and a working method thereof, and relates to a tool. At present, when the work is performed on a ground wire of a large-altitude difference and large-span circuit, the sag generated by a protection rope is excessive, so that the condition of a lead discharging to the protection rope is easily generated. The device comprises multiple connecting bridges detachably connected with the ground wire; the connecting bridges are arranged at intervals; the connecting bridges comprise fixing modules for connecting with the ground wire, locking modules for locking the fixing modules, and rope transfer and support modules connected with the fixing modules for transferring and supporting ropes; the fixing modules comprise steel sleeves, and elastic connecting pieces positioned on the inner sides of the steel sleeves; and the elastic connecting pieces and the steel sleeves are detachably connected. One connecting bridge is mounted by every other 50 meters, so that the sag generation is reduced, the reverse tension is prevented, the work safety is improved, and the electric shock accidents of operators are reduced.

Description

technical field [0001] The invention relates to a tool, in particular to a rope fixing device and a working method for a live line with a large height difference and a large span. Background technique [0002] UHV AC-DC transmission lines have the advantages of large transmission capacity, long transmission distance, small transmission loss, and line corridor saving. This is exactly the case in places with high and steep mountains, and there are often cases of large height differences and large gear distances on UHV lines. [0003] If working on the ground line of a line with a large height difference and a large span, the operator needs to use tools such as a soft ladder head to exit the iron tower, and at the same time install a protective rope on the soft ladder head, so that the soft ladder head and the operator can be pulled back to the iron tower by manpower. The soft ladder on which the workers ride slides 200-300 meters on the ground line, and the protection rope sh...
