Drop-out fuse pickup-hanging device

Abstract

The invention relates to a drop-out fuse pickup-hanging device. According to the technical scheme, the drop-out fuse pickup-hanging device comprises a lifting air cylinder, a lifting supporting base and a pneumatic device, the lifting air cylinder is arranged in the lifting supporting base, a work piston is arranged in the air cylinder, a multi-level lifting piston is arranged in the work piston,and the upper end portion of the lifting piston is connected with an opening and closing switch blade pickup-hanging hook through a pickup-hanging hook supporting rod; a lifting air cylinder base is arranged in a rotation track and connected with a track sliding block of the rotation track through a connecting pin, and a sealing piston and a transmission spring are arranged in an interlayer of therotation track; the lifting air cylinder base and the rotation track are movably connected; and the pneumatic device is connected to the rotation track and the lifting air cylinder, and rotating andlifting of the pickup-hanging hook supporting rod are achieved. The drop-out fuse pickup-hanging device has the beneficial effects that potential safety hazards that an electric worker conducts the pole climbing operation are reduced, mechanical operation is achieved as well, efficiency is improved, and danger is reduced; and abrasion of an arc extinguishing cover on the surface of a drop-out fuseis avoided, and the service life of the drop-out fuse 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.
