Problems solved by technology
The existing line clamp disassembly is generally to install a special disassembly piece on the top of an insulating rod, and then realize the loosening of the nut on the parallel groove clamp by rotating the insulating rod. However, when disassembling the parallel groove clamp in this way, Because the parallel groove clamp will shake with the cable, it will be difficult to disassemble and locate. Moreover, due to the poor rigidity of the cable, the clamp will often rotate when twisting, making disassembly more difficult. Further, this disassembly method It will also cause the displacement of parallel trench clamps and cables, which will bring certain hidden dangers to the safety of electricity use.

The invention provides a transmission line parallel-groove clamp quick disassembling assistance tool comprising a clamp gripping device, a hollow insulated rod and an insulated pull rod. The clamp gripping device includes an L-shaped movable chuck and a fixed roof. A support rod is arranged on the back side of the fixed roof, and the middle of the support rod is hinged to a support vertical plate arranged on the top end of the hollow insulated rod. The L-shaped movable chuck is disposed at one side of the upper end of the fixed roof. The insulated pull rod is sleeved in the hollow insulated rod, and the top end of the insulated pull rod is connected with the back end of the support rod through a connecting rod. The lower end of the insulated pull rod is a threaded rod, and the threaded rod is sleeved with an adjusting nut. The assistance tool is simple in structure, and convenient to operate. With the device, an operator can grip and fix a clamp at a high place on the ground, and a fastening bolt on the clamp can be dismounted quickly.
Description
technical field [0001] The invention relates to an auxiliary tool for quick disassembly and assembly of parallel ditch line clamps of power transmission lines. Background technique [0002] With the continuous development of the power industry, there are more and more power construction projects, resulting in more and more power maintenance work. When the cables on some high-voltage poles are overhauled or installed, it is usually necessary to clamp the cables through parallel trench clamps, and then send the cables and parallel trench clamps to the corresponding position of the high-voltage poles through the insulating rod. After the cables are placed, the parallel trench clamps are removed by some dismantling devices. The existing line clamp disassembly is generally to install a special disassembly piece on the top of an insulating rod, and then realize the loosening of the nut on the parallel groove clamp by rotating the insulating rod. However, when disassembling the pa...
