Small lifting device used for electric power maintenance

Abstract

The invention discloses a small lifting device used for electric power maintenance. The small lifting device comprises a bottom plate. The lower surface of the bottom plate is fixedly connected with four mounting blocks with the hollow interiors. The mounting blocks are uniformly distributed on the lower surface of the bottom plate. Threaded pins are inserted into the outer surfaces of the mounting blocks correspondingly and are in threaded connection with the threaded pins through threaded holes correspondingly. The ends, located in the mounting blocks, of the threaded pins are rotationally connected with first hinged seats through bearings correspondingly. According to the small lifting device, by arranging a driving motor, the driving motor drives a first threaded rod and a second threaded rod to rotate when adjusting of the working height causes variation of the center of gravity, two threaded sleeves are made to move close to or away from each other and drive supporting rods to open and close according to the working height, the two supporting rods, the first threaded rod and the second threaded rod form a triangle stable structure, a stable supporting effect is achieved, andtherefore, the purpose that the safety of the device is improved is achieved.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a small lifting device for electric maintenance. Background technique [0002] Power equipment mainly includes power generation equipment and power supply equipment. Power generation equipment is mainly power plant boilers, steam turbines, gas turbines, water turbines, generators, transformers, etc. Power supply equipment is mainly transmission lines of various voltage levels, transformers, contactors, etc. device and so on. [0003] With the popularization of electric power equipment, small lifting devices for electric power maintenance are becoming more and more important. The existing maintenance devices for circuit lifting on the market often use tools such as ladders and elevators, which are not suitable for long-term labor of workers. When it is at a high place, the center of gravity moves upwards, which makes it easy to tilt and fall, and the safety is low. C...
