Problems solved by technology
The energy storage unit pumps water to generate electricity, and the water flow is fast and the vibration force is large, which leads to loosening and serious wear of the trash rack, and it needs to be inspected once a year
During the maintenance process, the trash rack bar unit needs to be removed and lifted to the maintenance platform above the trolley, and other lifting equipment cannot be used close to it.
Due to the high stroke, manual chain hoists are required to disassemble and assemble, resulting in a rather long maintenance time, wasting a lot of manpower and material resources, increasing labor intensity, and causing unsafe factors

The invention discloses a storage power station trash rack overhauling lifting device which comprises trolley girder and a winch base arranged on the trolley girder. A winch is arranged on the winch base, a supporting pulling rod is arranged on the rear side of the winch, a main rod is arranged in front of the winch, the lower end of the main rod is connected with the winch base through a foundation bolt, the middle of the main rod is connected with the supporting pulling rod through a pulling rod, a pulley and a rope guide wheel are arranged on the main rod, a lifting hook is connected with one end of a steel wire rope, and the steel wire rope is connected with the winch via the pulley and the rope guide wheel. The storage power station trash rack overhauling lifting device is reasonable in structure, high in security coefficient, convenient to operate and free of affecting normal operating of a trolley, and improves the working efficiency of overhauling.
Description
technical field [0001] The invention relates to a lifting device for disassembly and maintenance, in particular to a lifting device for maintenance of trash racks in energy storage power stations. Background technique [0002] Each unit of the energy storage power station has 2 hole trash racks, each hole is composed of 3 sections, and each section is composed of 4 grid units, and each unit is composed of 12 grid bars, compartment pipes, connecting rods, and bolts. The grid bars are fixed on the frame by U-shaped bolts. The pumping power generation of the energy storage unit has a rapid flow of water and a large vibration force, which leads to loosening and serious wear of the trash rack, and it needs to be checked and repaired once a year. During the maintenance process, the trash rack bar unit needs to be removed and lifted to the maintenance platform above the trolley, so that other lifting equipment cannot be used close to it. Due to the high stroke, the dismantling an...
