Description

Technical Field

[0001] The utility model belongs to the technical field of fan cleaning, in particular to an SM fan cleaning platform. Background Art

[0002] An SM fan is a machine used to transport gas. It uses mechanical energy to increase gas pressure and discharge the gas. The fan's operating principle is to use high and low pressure to control gas flow and direction. Common fan types include centrifugal fans and axial flow fans. During operation, an SM fan may experience abnormally increased vibration. This may be due to an imbalance caused by excessive dust on the impeller blades. In this case, the fan blades must be thoroughly cleaned before the fan can resume operation. However, in actual use, the following disadvantages still exist:

[0003] During the cleaning process, the fan has large components and needs to be directly disassembled for cleaning. It needs to be lifted by a bridge crane and placed on the ground. When the area and space of the factory are limited and a bridge crane cannot be arranged, the fan needs to be partially disassembled for cleaning and cleaned carefully, which is inconvenient.

[0004] During the cleaning process of the fan, the operator needs to clean it with cleaning water. When cleaning through a platform, the water delivery pipe of the cleaning water needs to be guided to the platform for the operator to use. However, the water pipe is usually flexible. When the operator makes a mistake, the water pipe is easy to fall under the cleaning platform and needs to be redirected to the platform. The layout of the water pipe is not stable enough. Utility Model Content

[0011] Furthermore, three reinforcing plates are fixed on both sides of the upper bracket, all of which are fixed to the bottom of the working platform, and the reinforcing plate below the upper bracket is fixed on support column 2, thereby increasing the connection strength between the working platform and the upper bracket and the reinforcing plate.

[0012] Furthermore, support rods are fixed at equal distances on the two long sides of the top of the working platform, and a protective frame is fixed to the top of all the support rods. One end of the protective frame is open, so that when working, the components such as the fan head to be cleaned can be dragged onto it for cleaning.

[0013] Furthermore, a connecting plate is fixed on the closed end face of the protective frame, a movable hole is opened vertically through the connecting plate, a vertical plate is fixed at the edge of the top of the connecting plate away from the protective frame, a threaded rod is connected with a threaded rod at the lower part of the vertical plate, a flexible pressure plate is fixed to the end of the threaded rod close to the protective frame, the flexible pressure plate is arranged above the connecting plate, and a rotating frame is fixed to the end of the threaded rod away from the flexible pressure plate, the water pipe for cleaning is passed through the movable hole in the connecting plate, and the threaded rod is driven to rotate by rotating the rotating frame, and the flexible pressure plate is driven to change position.

[0014] The utility model has the following beneficial effects:
