[0002] Compound air cooling plays an important role in chemical production and has a significant effect on reducing the temperature in the chemical process. Compound air-cooled water pumps will leak when used for too long. Since most compound air-cooled water pumps are vertical pumps and directly connected to the motor, the motor needs to be removed before the water pump can be repaired. Usually, lifting equipment is used to hoist and repair the water pump;

[0003] As shown in the reference case "A composite air-cooled water pump maintenance lifting device" announcement number "CN220149072U", by hanging the lifting belt connected to the water pump on the lifting hook, controlling the telescopic cylinder to rise upward, the front end of the telescopic arm is raised, the water pump is lifted out, and the support arm is rotated to rotate the water pump out. It has the advantages of convenient movement and lifting, and at the same time solves the problem of high safety hazards when lifting the water pump out by manpower;

[0004] Although existing lifting equipment can easily lift and transfer the water pump, due to the shape and weight distribution of the water pump, the water pump may shake in the air during the lifting process. If the water pump collides with a wall or other hard objects during the movement, it is easy to cause secondary damage to the water pump.

[0005] Therefore, a lifting device for water pump maintenance is proposed to solve the above problems. Utility Model Content

[0024] like Figure 2 and Figure 3As shown, the stable lifting assembly 32 includes two movable frames 321 slidably mounted on one side of the hanger 31, and the same bidirectional screw 322 is installed between the two movable frames 321, and the bidirectional screw 322 is threadedly connected to the two movable frames 321 respectively. A plurality of support blocks 325 are fixedly installed on the top of the hanger 31, and telescopic ribs 326 are fixedly installed between the plurality of support blocks 325 and the hanging rope 21. A spring 327 is sleeved on the outer side of the telescopic rib 326, and the two ends of the spring 327 are fixedly connected to the support blocks 325 and the hanging rope 21 respectively. When lifting the water pump, the bidirectional screw 322 can be rotated to perform threaded movement with the two movable frames 321 at the same time, and the two movable frames 321 can be controlled to move closer to or away from each other to fix and lift the water pump. When the water pump is raised, the telescopic ribs 326 and springs 327 at the four corners can be used in conjunction with each other to ensure that the water pump is in a stable state. The pump remains balanced during the transfer process, which improves the safety and stability when the water pump is hoisted. The stable hoisting component 32 also includes a limit plate 324 fixedly installed on one side of the movable frame 321. The movable frame 321 and the limit plate 324 form an L shape.

When the water pump is raised, the expansion ribs 326 and springs 327 at the four corners can be used in conjunction to ensure that the water pump remains balanced during the transfer process, thereby improving the safety and stability when hoisting the water pump. When the two movable frames 321 are brought closer to each other to fix the water pump, the limiting plate 324 can be used to contact the bottom of the water pump to limit the bottom of the water pump, so that The water pump is more stable during hoisting, and the protective pad 331 helps to protect the surface of the water pump from being scratched or damaged during hoisting, thereby maintaining the appearance and functional integrity of the water pump. The protective pad 331 also helps to absorb the vibration generated during transportation, further improving the safety of the water pump during hoisting. Multiple contact wheels 334 can provide buffering and protection during mobile hoisting to prevent the hanger 31 from directly colliding with other obstacles during movement.
