Description

Technical Field

[0001] The present invention relates to the technical field of overhaul lifting devices, and particularly to an overhaul lifting device for 110 kV switches. Background Art

[0002] The overhaul lifting device for 110 kV switches is a special auxiliary tool used for maintaining and overhauling switch equipment with a voltage level of 110 kV in the power system. The main function of this device is to safely and efficiently move or replace heavy switch components during the overhaul process;

[0003] During the overhaul of 110 kV switches, workers will use large machinery such as cranes, aerial work platforms, and excavators to enter the substation. The switch is hoisted by ropes and hook mechanisms, and the switch is moved to a suitable position for overhaul.

[0004] Due to the limited space in the substation and the large space required by large machinery such as cranes, aerial work platforms, and excavators, it is necessary to expand the power outage range of the substation during the overhaul of the switch. If there is a slight mistake during the hoisting of the switch for overhaul, there may be a situation where equipment accidents occur, thus increasing the construction cost of the switch overhaul hoisting. When the crane hoists the switch, it is necessary to use both the hook mechanism and the rope to hoist the switch, and the operation is relatively inconvenient, thus reducing the overhaul hoisting efficiency of the overhaul hoisting device for the switch. If a robot is used to carry the switch, the overhaul cost of the switch will be increased. Summary of the Invention
