Description

Technical Field

[0001] The utility model relates to the technical field of large-scale fan maintenance, in particular to a fan maintenance and disassembly platform. Background Art

[0002] A fan is a machine used to compress and transport gas. It is widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and air intake of boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances; drying and selection of grains; inflation and propulsion of wind tunnel wind sources and hovercraft, etc. Large fans are needed in thermal power plants or wind power industries, and large fans need to be repaired and disassembled after failure.

[0003] Due to their huge size, large fans need to be lifted by gantry cranes during maintenance and disassembly, and then multiple workers need to disassemble them. During the disassembly process, the large fans are always in a lifted state, which is dangerous. In addition, after long-term use, some tricky positions of large fans are rusted and difficult to disassemble. Workers need to rotate the large fans to change the angle before disassembly, which is inconvenient. Therefore, we propose a fan maintenance and disassembly platform. Utility Model Content
