Problems solved by technology

[0002] Existing substations generally seldom have large-scale power outages. Live equipment, high-voltage busbars and lines are intricately intersected. The maintenance interval is small or other interval busbars are not powered off, and power failure means power supply loss. At present, the small interval electrical equipment in substations is below 400kg. , the lifting height is seven meters, so the electrical equipment weighing hundreds of kilograms outdoors cannot be safely dismantled and installed by manpower

Abstract

The invention provides a small interval dual-purpose hoisting device. The small interval dual-purpose hoisting device comprises a hoisting device and a trolley capable of moving heavy goods, wherein the hoisting device comprises a bottom fixing base; the bottom fixing base is fixedly arranged on the ground by a pair of pin rods; the bottom fixing base is vertically fixedly provided with logs. For the problem in prior art that outdoor electric equipment with the weight of hundreds jin cannot be manually and safely dismounted and mounted in a hoisting manner, the dual-purpose hoisting device adopting a vertical electric manner and a manual control manner is adopted, so that the electric equipment can be conveniently mounted in the hoisting manner and manually and safely dismounted.

Description

technical field [0001] The invention relates to the technical field of power maintenance of substations, in particular to a dual-purpose lifting device for small intervals. Background technique [0002] Existing substations generally seldom have large-scale power outages. Live equipment, high-voltage busbars and lines are intricately intersected. The maintenance interval is small or other interval busbars are not powered off, and power failure means power supply loss. At present, the small interval electrical equipment in substations is below 400kg. , the lifting height is seven meters, so the electrical equipment weighing several hundred kilograms outdoors cannot be safely dismantled and installed by manpower. Contents of the invention [0003] Aiming at the above problems in the prior art, the present invention provides a dual-purpose lifting device for small intervals, so that lifting installation and manual safe removal can be carried out. [0004] The present inventi...
