Live working strain front-end clamping tool for fast locking-type lead wire of front strain clamp

Abstract

The invention discloses a live working strain front-end clamping tool for a fast locking-type lead wire of a front strain clamp, which comprises a walking mechanism, wherein a traversing mechanism is arranged at the back of a shell of the walking mechanism; a rotating mechanism is arranged on a transverse moving seat of the traversing mechanism; an adjusting mechanism is arranged on the rotating mechanism; a turning articulated seat is arranged at the front end of a rotating rod of the adjusting mechanism; the turning articulated seat is articulated with the back end of a tool for replacing an insulator; a turning driving motor is arranged on the turning articulated seat; a locking mechanism is arranged on the tool for replacing the insulator; a front strain clamp of the tool for replacing the insulator comprises two clamping plates; one end of a first clamping plate is articulated with the middle part of a second clamping plate; one end of the second clamping plate is articulated with one insulating rod; and the other end of the second clamping plate and the other end of the first clamping plate are respectively connected with the other insulating rod by fast locking bolts.

Description

technical field [0001] The invention relates to a tension-resistant front-end clamping tool for live working wires of a quick-lock type wire with a front-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 break...

[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.

In addition, the tension-resistant front end clamps of the existing replacement tools need to be fixed with the existing bolts and nuts. The operation process is relatively cumbersome and takes a long time. Moreover, during the operation process, the nuts are prone to fall, which affects the operation progress on the one hand, and on the other hand. On the one hand, it will pose a threat to the personnel under the tower
