A kind of hook-and-reel device

Abstract

The invention relates to an electric power outer wire tool. According to the technical scheme, the electric power outer wire tool comprises a lifting air cylinder, a lifting supporting base and a pneumatic device, wherein the lifting air cylinder is mounted in the lifting supporting base; a working piston is mounted in the air cylinder; a multi-stage lifting piston is mounted in the working piston; the upper end of the lifting piston is connected with an opening and closing knife switch hook through a hook supporting rod; a lifting air cylinder base is mounted in a rotating track and connectedwith a track sliding block of the rotating track through a connecting pin; a sealing piston and a transmission spring are mounted in an interlayer of the rotating track; the lifting air cylinder baseis movably connected with the rotating track; and the lifting air cylinder base is connected to the rotating track and the lifting air cylinder through the pneumatic device, and therefore the hook supporting rod can rotate and ascend and descend. The electric power outer wire tool has the advantages that potential safety hazards of pole climbing operation of electric power workers are reduced, mechanical operation is achieved, efficiency is improved, and danger is reduced; an arc extinguishing cover on the surface of a line connector is prevented from being abraded, and the service life of the line connector is prolonged.

Description

technical field [0001] The invention relates to an electric power outside line tool and method, in particular to a hook-and-twist device. Background technique [0002] In electric power work, Lingke is the insurance between the 10000v high voltage in the distribution room and the switchboard or transformer, also called drop-out insurance and drop-out fuse. Generally, three are installed, one for each of the three phases. It forms a 45-degree angle with the ground when it is switched on. Once the fuse inside is blown, hot gas or even flames will be ejected from the bottom of the fuse tube, and then the linkage device will act to make it fall, and it will be in an upside-down state. It can be seen, so that it can be found during maintenance. It does not fall to the ground when it fuses, but hangs on a high-voltage utility pole, and does not send a signal to maintenance personnel. Generally, in the work of the electric power line, the removal and hanging of the gram is accom...

AI Technical Summary

Problems solved by technology

The problems in actual use are: since the gram is generally installed in a higher position, it brings a lot of trouble to the electric power workers, mainly in the following: one is working at heights, and the other is the special environment, usually in the field. The third is the need for anti-electricity, etc., and the fourth is that it is necessary to manually hold the gram stick on the ground or climb to the electric pole and then hold the gram stick to operate the gram to realize the removal and hanging operation

The problem is that it only improves the rod and adds multiple functions, but it does not completely solve the disadvantages of manually lifting the rod to remove and hang the rod

The existing problem is: the patented technology is still operated by manual lifting of the rod, and the operation of the mechanical rod is not realized.
