Problems solved by technology
[0004] The parallel ditch lap joint is an important tool for high-voltage live work, and it is the most commonly used work tool for live work personnel. However, there are many types and models of the existing lap joints, which are inconvenient to use, heavy, and cannot handle different wire diameters. There are problems such as parallel ditch wire clips, so the quality of the lap is not high, the efficiency of the lap is low, and the operators are reluctant to use it. In addition, the existing lap splicer has a complex structure and high cost, which is inconvenient to popularize.

The invention discloses an efficient hot-line work parallel groove lap joint device and an operation method thereof. The device comprises two wire clamps. The wire clamps comprise an upper wire clampand a lower wire clamp. The upper wire clamp and the lower wire clamp are connected through a bolt. The upper wire clamp is in a left square hole and a right square hole in a positioning plate. The positioning plate is fixedly connected with the side wall of a thread sleeve through a back plate; a supporting plate capable of relatively sliding up and down is arranged between the positioning plateand the back plate, two ends of the supporting plate are fixedly connected with the outer wall of a bearing, a screw is arranged in the thread sleeve, the screw penetrates through the bearing and is fixedly connected with the inner ring of the bearing, the bottom end of the screw is connected with an insulating rod through a connecting piece, the side edge of the bottom of the supporting plate isfixedly connected with a lug plate, and a drainage wire is on the lug plate and passes through the wire clamps. The device can be used for conveniently and quickly carrying out electrified parallel groove lap joint operation, does not need to be powered off, and is simple in structure, light in weight and convenient to carry.
Description
technical field [0001] The invention relates to a ditch-merging device, in particular to a ditch-merging lapper for high-efficiency live-line work and an operation 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-groov...
