Description

Technical Field

[0001] This utility model belongs to the field of lifting equipment technology, and relates to a lifting device for pump station maintenance. Background Technology

[0002] Currently, pumps in small underground booster pump stations are mostly installed using guide rails, which are located below the standing platform. After the pump station is built and put into use, the high sludge content in the sewage often causes blockages or damage to the internal pump equipment, often requiring the equipment to be removed for cleaning or repair. The traditional method is to manually lift and disassemble the equipment to be treated and place it on the standing platform, and then use slings to lift the equipment out. The first stage of the operation involves working in a confined space, where workers spend a long time in the enclosed space, posing significant safety hazards and risks, and easily causing accidents. In the second stage of the operation, when using slings to lift the equipment, the workers' standing point is close to the work opening, and they are in a tensioned state, which easily leads to falls.
