Technical Field

[0001] The utility model relates to a rotatable cantilever lifting device for lifting a submersible pump, belonging to the technical field of submersible pump lifting devices. Background Art

[0002] Submersible pumps are important equipment for deep well water extraction. They are mainly divided into clean water submersible pumps and sewage submersible pumps (also known as submersible sewage pumps). When in use, the entire unit submerges into the water to extract groundwater to the surface. It can also be used in water extraction projects such as rivers, reservoirs, and canals. It is a commonly used equipment for domestic water use, mine rescue, industrial cooling, farmland irrigation, seawater lifting, and ship loading.

[0003] At present, when lifting a submersible pump in a container (for example, a lifting well, a pool, or a well), manual lifting or electric hoist lifting is generally adopted. Although electric lifting operation can save labor and avoid safety risks compared with manual lifting operation, the existing electric hoist lifting requires the use of a gantry, which is not only more complex in structure and occupies a large area, but also cannot adjust the retractable position and angle of the submersible pump according to the needs of the user, which makes it very inconvenient for the user to use the submersible pump and has great limitations.

[0021] Example

[0022] See also Figures 1 to 3 As shown, the utility model provides a rotatable cantilever lifting device for lifting a submersible pump, comprising a vertically arranged cantilever support column 1, a horizontally rotatable cantilever 2 is provided on the top of the cantilever support column 1, a pulley 3 is provided on the top of the cantilever 2, a winch 4 is provided in the middle of the cantilever 2, a steel wire rope 5 is provided on the pulley 3, one end of the steel wire rope 5 is used to connect with a submersible pump 8, and the other end of the steel wire rope 5 is connected to the winch 4 after passing through the pulley 3.

[0023] In this embodiment, a slewing bearing 6 is fixedly provided on the top of the cantilever support column 1, the cantilever 2 is fixed to the top of the inner ring 6-1 of the slewing bearing, and the bottom of the outer ring 6-2 of the slewing bearing is fixedly connected to the top of the cantilever support column 1. Through the slewing bearing 6, the cantilever 2 can rotate 360 ​​degrees around the cantilever support column 1, thereby driving the submersible pump 8 to rotate 360 ​​degrees, and then the position and angle of the submersible pump can be conveniently adjusted according to the needs of the user.

[0024] Specifically, see Figure 4 As shown, in this embodiment, the top of the cantilever support column 1 is provided with an upper flange 1-1 for fixedly connecting with the outer ring 6-2 of the slewing support bearing, and the bottom of the cantilever support column 1 is provided with a lower flange 1-2 for installation and fixation.

[0025] In this embodiment, the slewing bearing 6 is preferably a gearless slewing bearing to avoid adverse effects on the lifting and lowering of the wire rope 5 .

[0026] In addition, the winch 4 can be an electric winch or a manual winch or an integrated electric and manual winch. Preferably, it is an integrated electric and manual winch with a self-locking mechanism, so that it can be lifted by electric means under normal conditions and by manual means when the power is off, and it can achieve self-locking to stop the lifting of the wire rope 5 when it reaches the lifting position.

[0027] In addition, in this embodiment, a rotating handle 7 is provided at the lower portion of the cantilever 2. With this design, when the cantilever 2 needs to be rotated to adjust the angle of the submersible pump, the cantilever 2 can be rotated by rotating the handle 7, which is easy to operate and saves effort.

[0028] It should be noted that the submersible pump 8 described in the present invention can be a clean water submersible pump or a sewage submersible pump.

[0029] The method of using the rotatable cantilever lifting device for lifting a submersible pump provided by the utility model is as follows:

[0030] See also Figure 5 As shown, firstly, the cantilever support column 1 is installed on the ground at any position of the outer periphery of the outlet of the pool or well 9. The specific implementation method of this embodiment is: the lower flange 1-2 at the bottom of the cantilever support column 1 is fixedly connected to the ground (it can be fixed by studs); then the submersible pump 8 is fixedly connected to the lower end of the wire rope 5 on the ground, thereby completing the installation of the rotatable cantilever lifting device described in the utility model;

[0031] Then, by releasing the winch 4, the steel wire rope 5 and the submersible pump 8 are lowered together. When the submersible pump 8 is lowered to the required depth, the winch 4 is locked to stop the steel wire rope 5 from descending, and the submersible pump 8 can be fixed at the required depth in the pool or well 9. After the submersible pump 8 is fixed to the required depth, if the angle of the submersible pump 8 needs to be adjusted, the cantilever support column 1 can be rotated by rotating the handle 7 to achieve the angle adjustment of the submersible pump 8.

[0032] When the submersible pump 8 needs to be lifted from the pool or well 9, the wire rope 5 is driven up by the winding winch 4, which can drive the submersible pump 8 to rise together. When the submersible pump 8 rises to the required height, the winch 4 is locked, and then the cantilever support column 1 is pushed to rotate by turning the handle 7, so that the submersible pump 8 can change its angle to the required position.

[0033] From the above, it can be seen that the rotatable cantilever lifting device provided by the utility model, compared with the traditional gantry lifting device, is not only simple in structure, occupies a small area, is easy to install and use, and has good safety, but also can realize 360-degree rotation of the submersible pump, and can realize convenient adjustment of the position and angle of the submersible pump according to the needs of the user, which can significantly improve work efficiency and reduce the labor intensity of the staff; therefore, the utility model has obvious practical value.

[0034] Finally, it is necessary to point out that the above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be covered within the protection scope of the utility model.
