Live working insulator replacement tool for self-locking conductors with rear tension clamps

Abstract

The invention discloses a self-locking type live-line work insulator replacing tool with a back strain clamp for a wire. The self-locking type live-line work insulator replacing tool comprises a traveling mechanism, a transversely moving mechanism is arranged at the back of a shell of the traveling mechanism, a transversely moving seat of the transversely moving mechanism is provided with a rotating mechanism, a regulating mechanism is arranged on the rotating mechanism, a turnover articulating seat is arranged at the front end of a rotating rod of the regulating mechanism, a turnover drive motor is arranged on the turnover articulating seat, and the back strain clamp of the insulator replacing tool is provided with a locking mechanism; the locking mechanism is formed by connecting two clamp boards, an electrically operated push rod, a door-shaped press block, inclined blocks, a tension spring and pressing plates; the two clamp boards are arranged at the back of the insulator replacing tool in parallel; cavities in the back strain clamp and the clamp boards are communicated to form a cavity, the electrically operated push rod is arranged in the cavity, the door-shaped press block is arranged at the upper end of the electrically operated push rod, and two wedge-shaped push blocks are arranged at the lower end of the door-shaped press block; and the clamp boards are provided with through slots, the inclined block is respectively arranged in the cavity of each clamp board, and the inclined blocks extend out of the through slots and are provided with the pressing plates.

Description

technical field [0001] The invention relates to a live working insulator replacement tool for a self-locking wire of a rear tension clamp. Background technique [0002] At present, in the ultra-high voltage power transmission and transformation industry, there are great potential safety hazards in the process of using existing tools to replace line insulator strings with electricity. The main reason is that it needs at least two workers to cooperate to replace the insulator string with the existing tools, and, because the installation position of the insulator is that one end of the insulator is close to the wire tower, and the other end is installed away from the wire tower, therefore, at least one A staff member must leave the wire tower completely and carry out high-altitude operations under the condition that the whole body is suspended on the transmission line. The safety of the operation is low, and the transmission line is prone to breakage, causing accidents of high...

[0002] At present, in the ultra-high voltage power transmission and transformation industry, there are great potential safety hazards in the process of using existing tools to replace line insulator strings

The main reason is that it needs at least two workers to cooperate to replace the insulator string with the existing tools, and, because the installation position of the insulator is that one end of the insulator is close to the wire tower, and the other end is installed away from the wire tower, therefore, at least one One worker has to work at heights while completely leaving the wire tower and the whole body is suspended on the power transmission line. The safety of the operation is low, and the power transmission line is prone to breakage, resulting in accidents of high falls and casualties.

Using automated replacement tools to replace manual labor is the preferred method to solve high-altitude operations, but because existing automated replacement tools are difficult to automatically lock insulators, they have no practical value
