[0002] The furnace bottom of the hot rolling heating furnace bottom drainage system is about 9 meters below the horizontal plane. A drainage pit is set at the loading end of each furnace. The drainage pit is generally 3*1.5 meters and 5 meters deep. Each drainage pit is equipped with 2 submersible pumps, which are used to drain the water inside the flue or the equipment cooling water to the ground drainage ditch to prevent the flue at the bottom of the furnace from being flooded. However, there are the following problems when replacing the submersible pump: 1) The drainage pit opening is 3*1.5 meters, and the lower submersible pump opening is only 1*1.5 meters. The rest is paved with steel cover plates. The submersible pump weighs 40Kg, and the total weight of the fire hose and stored water exceeds 60Kg. 1) During replacement, three people are required to pull the submersible pump to the ground, two people are required to properly pull the rope that ties the submersible pump, and one person is required to pull the cable and fire belt. The lifting rope is slippery due to impurities such as oil in the water, and it is easy to slip during operation, making the operation difficult and inefficient; 2) The working space is small, and the workers gather at the pit mouth, which can easily cause people to fall into the pit and cause drowning and falls; 3) The sewage pit is close to the flue, the flue gas temperature is 800℃, and the external environment temperature is as high as 50-70℃ in summer. It takes three people 2 hours to replace a submersible pump, which can easily cause heat stroke. Summary of the invention
