Problems solved by technology

[0002] At the construction site such as line T connection and 35kV substation busbar and jumper connection of isolating switch, it was found that the operation of T-shaped clamps was troublesome. Since the operation was a high-altitude operation, it was necessary to hold the ladder with one hand and operate with the other hand, which was very uncomfortable. Convenient, the hexagon nut and U-shaped ring may fall down if you don’t pay attention

Abstract

The invention discloses a hinge type middle jointing clamp which comprises a hinge structure, an elastic taper sleeve, a hexagonal nut, a spring spacer and the like, wherein two jointing seats form the hinge structure through bolts. The hinge type middle jointing clamp disclosed by the invention can be divided into various types according to the different line diameters of single-end and double-end jointing clamps and a main line rope connected with the single-end and double-end jointing clamps, and is suitable for the jumper connection of the T-shaped joints of lines, the bus and isolating switch of a base station and the like. Compared with the traditional T-shaped jointing clamp, the hinge type middle jointing clamp disclosed by the invention has the advantages of rapidness and convenience in installation and the like.

Description

Technical field: [0001] The invention relates to a hinged intermediate clamp, which can be divided into various types according to the diameter of the single-headed, double-headed clamp and the connected main cable, and is suitable for T-connection of lines and jumper wires between bus bars and isolating switches in substations. connection etc. Background technique: [0002] At the construction site such as line T connection and 35kV substation busbar and jumper connection of isolating switch, it was found that the operation of T-shaped clamps was troublesome. Since the operation was a high-altitude operation, it was necessary to hold the ladder with one hand and operate with the other hand, which was very uncomfortable. It is convenient, and the hex nut and U-shaped ring may fall down if you don't pay attention. Invention content: [0003] In order to overcome the defects of the prior art, the object of the present invention is to provide a hinged intermediate clamp, whi...
