Universal hoisting equipment for transformer substation overhauling

Abstract

The invention relates to the technical field of transformer substation equipment overhauling, in particular to universal hoisting equipment for transformer substation overhauling. The universal hoisting equipment comprises a hoisting device, a rotation device, a stand column and a base, all of which are sequentially connected from top to bottom. The universal hoisting equipment further comprises an isolation switch special sling. The hoisting device can horizontally rotate around the axis of the stand column by 360 degrees. The hoisting device comprises a lazy arm and further comprises a fronthook frame, a movable pulley frame, a rotation frame and a hoisting type winch, all of which are sequentially fixed to the lazy arm in a front-back manner. A movable pulley, a fixed pulley and a hookare further included. The fixed pulley is fixed to the movable pulley frame. The movable pulley is arranged on a steel wire rope between the movable pulley frame and the front hook frame. The hook isfixed to the position below the movable pulley, and the isolation switch special sling is hung on the hook. The hoisting type winch rotates and drives the hook to ascend and descend. Universality ishigh, and the universal hoisting equipment can be arranged on all 66kV isolation switch frameworks, arranged in various forms, of a transformer substation. The universal hoisting equipment is small inweight and suitable for aerial work. Assembling is flexible and convenient, and the hoisting capacity is high. The universal hoisting equipment can be used for first-aid repairing of vehicles. The isolation switch hoisting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of substation equipment maintenance, in particular to a general hoisting equipment for substation maintenance. Background technique [0002] At present, for substation equipment maintenance, especially substation isolating switch disassembly maintenance or overall replacement, it is necessary to hoist the old isolating switch from the frame, and hoist the overhauled isolating switch or new isolating switch to the frame. At present, the first type of hoisting equipment used in this operation is to use the manual method, but due to the limitation of manpower, only a single column of each item can be hoisted at a time; the second type is to change the power of hoisting to an electric motor, and the hoisting weight will increase to a certain extent , but the operation and assembly are more cumbersome. [0003] In addition, the following problems still exist in the application process: [0004] 1. The installat...

Problems solved by technology

[0006] 3. The weight of the hoisting equipment is too heavy, and it is very difficult to move and assemble the disconnectors arranged at high places.

[0007] At present, in the construction of substations, cranes are still used for some light-weight equipment, but the space between some substations is limited. In order to ensure a sufficient safe distance from live equipment, the scope of work has to be expanded
