[0002] Submersible sewage pumps are widely used to discharge sewage containing solid particles and fibrous materials. In view of its harsh working environment and frequent operation requirements, the installation, maintenance and replacement of submersible sewage pumps are particularly important. Traditional submersible sewage pump lifting equipment usually adopts a truss crane with an electric hoist and is fixed above the sewage pool. Steel cables are pre-set on the submersible sewage pump. During lifting, workers need to go deep into the sewage pool to connect and fix the steel cables with the hooks, and then lift it to the top. However, since the depth of the sewage pool is usually more than ten meters, the lifting process of the submersible sewage pump requires multiple connections and fixation before it can be lifted above the sewage pool. In addition, traditional equipment is bulky and the equipment utilization rate is not high, which not only increases maintenance costs, but also limits the improvement of work efficiency.
