Line patrol operation obstacle removing device

Abstract

The invention discloses a line patrol operation obstacle removing device. The line patrol operation obstacle removing device comprises a clamping jaw device and a cutting device, wherein the cutting device is positioned on one side of the clamping jaw device; the clamping jaw device comprises a clamping jaw; a fixed plate and a movable block are arranged on two sides of the clamping jaw respectively; two clamping arms of the clamping jaw are arranged on the fixed plate through first fixed pins respectively; a second fixed pin is fixed on each of the two clamping arms of the clamping jaw; inclined grooves in positional correspondence to the second fixed pins are formed in the movable block; each second fixed pin penetrates through the corresponding inclined groove and is positioned on the lower part of the corresponding first fixed pin. The line patrol operation obstacle removing device provided by the invention is simple in structure, low in cost, convenient to implement, high in reliability, high in obstacle removing capacity and good in application prospect.

Description

technical field [0001] The invention belongs to the field of line inspection robot mechanisms, and in particular relates to an obstacle removal mechanism for line inspection operations. Background technique [0002] In order to ensure the safety and stability of the operation of ultra-high voltage transmission lines, it is necessary to carry out regular inspections on the transmission lines. Some foreign objects such as kite lines and plastic sheets are often hooked on the transmission lines, which is very important for the safety and stability of the transmission lines. Therefore, it is necessary to remove foreign objects in time. In the past, when removing foreign objects on transmission lines, maintenance workers were required to board the transmission lines to remove them. The maintenance was intensive, difficult, and low in safety. Chinese patent 200620090882.6 discloses a wire hanger remover. The operator controls the remover on the ground, and the scissors on the remo...

Problems solved by technology

[0002] In order to ensure the safety and stability of the operation of ultra-high voltage transmission lines, it is necessary to carry out regular inspections on the transmission lines. Some foreign objects such as kite lines and plastic sheets are often hooked on the transmission lines, which is very important for the safety and stability of the transmission lines. Therefore, it is necessary to remove the foreign matter in time. In the past, when removing the foreign matter on the power transmission line, maintenance workers were required to board the power line to remove it. The maintenance intensity was high, the difficulty was high, and the safety was low.

Chinese patent 200620090882.6 discloses a wire hanger remover. The operator controls the remover on the ground, and the scissors on the remover cut off the foreign matter by pulling the rope. Since the operator is far away from the power line, the operation is inconvenient and cannot be done quickly. The handle of the scissors is well controlled, it is not easy to remove foreign objects and it is easy to scratch the power line and cause additional damage, and because a long rope is required to operate the scissors, the rope is easy to knot and the arrangement is cumbersome, which increases the time and difficulty of removing foreign objects; In addition, Chinese patent 201020652814.0 discloses an obstacle-clearing device for overhead transmission line patrol robots. This device cuts foreign objects short by motor-driven cutters. The obstacle removal device will be entangled, which will bring inconvenience and safety hazards to the foreign object removal operation. Therefore, the current line patrol operation obstacle removal mechanism has disadvantages such as poor controllability, high requirements on the working environment conditions, and inability to complete fixed-point removal of foreign objects. Therefore, Difficult to use in actual line inspection operations
