Movable trolley for maintenance of power transmission and distribution equipment

Abstract

The invention discloses a movable trolley for maintenance of power transmission and distribution equipment. The movable trolley comprises a bottom plate, the two sides of the top of the bottom plate are connected with a first vertical plate and a second vertical plate correspondingly, the first vertical plate and the second vertical plate are arranged in parallel, moreover, sliding grooves in thevertical direction are formed in the plate bodies of the first vertical plate and the second vertical plate, a first sliding plate and a second sliding plate are connected in the sliding grooves in asliding mode correspondingly, a bidirectional threaded rod is rotationally connected between the first sliding plate and the second sliding plate, one end of the bidirectional threaded rod extends tothe side, far away from the first sliding plate, of the second sliding plate and is provided with a polygonal sliding groove, a polygonal sliding rod is slidably connected in the polygonal sliding groove, one end of the polygonal sliding rod is fixedly connected with a spring set, and the other end of the polygonal sliding rod extends to the side, far away from the first sliding plate, of the second sliding plate and is fixedly connected with a knob. The movable trolley can be applicable to work of live places, good in anti-shock performance, convenient and fast in lifting, convenient to operate manually, relatively low in manufacturing and use cost, and meets the use requirements of people in production and life.

Description

technical field [0001] The invention relates to the technical field of power transmission and distribution equipment, in particular to a mobile trolley for maintenance of power transmission and distribution equipment. Background technique [0002] At present, in the maintenance and overhaul of the power system, some heavy materials, such as the entire set of isolating switches, large-scale construction material accessories, disassembled switch components, knife gates, etc., are mainly completed by cranes and cars. High, and because the surrounding is a live environment, the safety risk is relatively large. Therefore, it is necessary to design a motorized device that is suitable for working in live places, has good seismic performance, is convenient to lift, has low cost and use cost, and is convenient for manual operation. It cannot meet people's needs in production and life. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomi...
