Problems solved by technology
[0004] Ditch lap joint is an important tool for high-voltage live work, and it is the most commonly used working tool for live work personnel. However, there are many types and models of lap joints, and there are problems such as inconvenient use, heavy weight, and inability to handle different wire diameters. , so the quality of the lap joint is not high, and the operators are reluctant to use it. In addition, the existing lap joints are complex in structure, high in cost, and inconvenient to popularize

The invention discloses a parallel groove lap joint device capable of performing live work and an operation method of the parallel groove lap joint device. The device comprises an upper wire clamp anda lower wire clamp; the upper wire clamp and the lower wire clamp are connected through bolts; the upper wire clamp is positioned in a square hole in a positioning plate; a limiting plate is arrangedat the tops of the bolts; the positioning plate and the limiting plate are fixedly connected to the side wall of a sleeve; a screw rod is arranged in the sleeve; an end plate is fixedly connected tothe top end of the screw rod; the screw rod is provided with a threaded sleeve; the bottom end of the screw rod is connected with an insulating rod through a screw; symmetrical supporting plates are fixedly connected to two ends of the threaded sleeve; grooves are formed in the top ends of the supporting plates; and current drainage wires are located in the grooves and the wire clamps. According to the parallel groove lap joint device of the invention, the wire clamps are fixed in the positioning plate; the supporting plates capable of moving up and down are designed below the positioning plate so as to clamp the current drainage wires; the wire clamps are hung on an overhead conductor; the wire clamps are fastened through a nut sleeve; and the lap joint device can be taken down. With thetool adopted, live parallel groove lap joint operation can be carried out conveniently and rapidly, and power outage is not needed any more. The device of the invention has the advantages of simple structure, light weight and portable convenience.
Description
technical field [0001] The invention relates to a ditch parallel lap, in particular to a ditch parallel lap capable of live work and an operating method thereof, belonging to the technical field of electrical equipment maintenance operations. Background technique [0002] As the people's yearning for a better life is increasing, the business environment needs to be improved urgently, which puts forward higher requirements on the reliability of power supply. In order to improve the reliability of power supply, vigorously carrying out live work is currently widely adopted by power supply enterprises. a way of Due to the adoption of live work, the number of households lost due to power outages has been greatly reduced, and the satisfaction of ordinary people with electricity has been improved. In the live work, a large number of parallel-groove live laps are required, so it is of great significance to improve the benefits and efficiency of the parallel-groove live laps. [00...
