Abstract

The invention belongs to the technical field of tools for live operation and particularly relates to a remote control wrench used for high voltage live screw mounting or demounting. The remote control wrench comprises an insulating operating rod, an electric wrench, a remote control component, a locking device and a lifting device, wherein the electric wrench comprises an upper housing arranged on the insulating operating rod, a rotary motor placed inside the upper housing, and a rotating head connected with the rotary motor, the remote control component is in wireless connection with the rotary motor so as to control the rotating head to act, the locking device comprises a locking sleeve opposite to a locking head, and the lifting device is arranged on the insulating operating rod, is connected with the electric wrench and/or the locking device, and drives the electric wrench and the locking device to move in the axial direction along the insulating operating rod. According to the remote control wrench, during the use, the electric wrench and the locking device play an effect together to prevent a nut from autorotation, the requirements of different working conditions are met, risks caused by live operation of workers can be avoided, the labor intensity is lowered, and the work efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of live working tools, and in particular relates to a remote control wrench for disassembling and assembling high-voltage live screws. Background technique [0002] In electric power production, in live maintenance of transmission lines, power outage maintenance or project acceptance work, for the fastening and fastening inspection of metal bolts on the wire side such as jumper diversion boards, operators need to use heavy special tools to enter the work site The operation is labor-intensive, the work efficiency is low, and the operation is highly dangerous. In particular, the equipotential fastening and drainage equipment looses the heating bolts, and there is a high safety risk. [0003] In order to solve the above problems, the patent with the authorized notification number CN203747301U provides a remote control electric wrench for high-voltage live work, including an insulating operating rod, a housing a...
