Hot-line work split type ten-split wire lifting device

Abstract

The invention provides a hot-line work split type ten-split wire lifting device comprising two assemblies which are separable and mutually symmetrical, wherein each assembly comprises a fixture main body, joints, a long wire splitting hook rod, a short wire splitting hook rod, a transverse connecting plate and five wire splitting hooks; the outer side of the lower edge of the fixture main body is connected with the short wire splitting hook rod, and the inner side of the lower edge of the fixture main body is connected with the long wire splitting hook rod; the arranging positions of the five wire spitting hooks are as follows: the inner side of the upper edge of the fixture main body is provided with a U-shaped groove wire splitting hook, the outer side of the short wire splitting hook rod is respectively provided with an upper wire splitting hook, a middle wire splitting hook and a lower wire splitting hook, the inner side of the long wire splitting hook rod is provided with a wire splitting hook, and the short wire splitting hook rod and the long wire splitting hook rod are connected and fixed by the transverse connecting plate. Due to the design, the hot-line work split type ten-split wire lifting device is scientific and reasonable in structure, high in strength, safe and reliable, each force bearing point of the wire lifting device is in good contact with a split conductor, and the field inspection operation is safe and convenient.

Description

technical field [0001] The invention relates to a wire lifter for live work, which belongs to the technical field of power line maintenance tools, in particular to a split-type ten-split wire lifter for live work suitable for 1000kV ultra-high voltage compact lines. Background technique [0002] my country is one of the first countries in the world to carry out live work, and has quite mature experience in the development of live work equipment for 500kV and below lines. The wire lifter is a commonly used tool in the maintenance of transmission lines. It lifts the split wires of the high-voltage line during operation, so that the maintenance personnel can overhaul the insulators or fittings in relevant parts. The type of wire lifter is mainly designed according to the conductor load and splitting pattern of the transmission line. The 500kV line adopts a four-split wire lifter. With the completion of the 750kV line and the 1000kV UHV demonstration project, the splitting type ...
