[0019] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] See also Figure 1-4 , a vacuum pump supporting device includes a supporting frame 1, and first universal wheels 2 are installed at the four corners of the bottom of the supporting frame 1. The first universal wheels 2 are in rolling contact with the ground, which can facilitate the movement of the supporting frame 1 as a whole, and a brake pad is provided on the first universal wheel 2, which can make the supporting frame 1 stop at a required position. Screws 3 are rotatably provided on both sides of the supporting frame 1, and wire sleeves 4 are threadedly connected to the two sets of screws 3. A crossbeam 5 is fixedly connected between the two. A driving assembly acting on the screw 3 is provided on the top of the supporting frame 1. The two sets of screws 3 can be driven by the driving assembly to rotate synchronously. Since the wire sleeve 4 is threadedly connected to the screw 3, the two sets of screws 3 can be driven to rise and fall synchronously during the synchronous rotation of the two sets of screws 3, thereby controlling the rise and fall of the crossbeam 5 between the two sets of wire sleeves 4. To move, a hook 6 is connected to the middle of the bottom of the beam 5 through a steel wire rope, and the hook 6 can hook the lifting ear on the top of the vacuum pump. The front end of the bottom of the support frame 1 is an open structure, and a group of slide rails 7 are provided at its rear end. Two groups of support plates 8 are slidably connected to the slide rails 7 through sliders. The two groups of support plates 8 are used to support the feet on both sides of the vacuum pump. The support plates 8 extend to the front end of the support frame 1 and are provided with fixing holes 9. When the feet of the vacuum pump are placed on the support plates 8, the mounting hole positions of the feet of the vacuum pump will correspond to the fixing holes 9 on the support plates 8. At this time, the fastening bolts can be passed through the fixing holes 9 and the mounting holes on the vacuum pump and locked. The fixing holes 9 are distributed in multiple groups on the support plates 8, and the fixing holes 9 are strip-shaped, which can adapt to the mounting hole positions of different feet of vacuum pumps and eliminate the influence of installation errors.

[0022] After the lifting of the lifting device 1 is lifted, the lifting device 1 is lifted and the support 1 is lifted. At this time, the lifting device 1 is lifted and the support 1 is in a state of rotation and the lifting of the lifting device 1 is stopped. When the lifting device 1 is lifted, the lifting device 1 is in a state of rotation and the lifting of the lifting device 1 is stopped. When the lifting device 1 is lifted, the lifting device 1 is in a state of rotation and the lifting of the lifting device 1 is stopped. When the lifting device 1 is lifted, the lifting device 1 is in a state of rotation and the lifting of the lifting device 1 is stopped. When removing the vacuum pump from the support frame 1, first unscrew the fastening bolts between the fixing holes 9 and the mounting holes on the vacuum pump. At this time, the driving component can be used to control the crossbeam 5 to move upward and drive the vacuum pump to be lifted upward from the support plate 8. By controlling the support plate 8 to slide toward the outside of the support frame 1, the support plate 8 can be moved to the positions on both sides of the vacuum pump base. At this time, since the bottom of the vacuum pump is no longer blocked by the support plate 8, the driving component can be used to control the crossbeam 5 to move downward and drive the vacuum pump to fall to the ground. After untying the hook 6 from the lifting ear at the top of the vacuum pump, the support frame 1 can be pushed away, thereby completing the disassembly of the vacuum pump on the support frame 1. In summary, the staff can easily carry the vacuum pump to the support frame 1 and fix the vacuum pump on the support frame 1, and can also easily unload the vacuum pump on the support frame 1 to the required location. In this process, the staff does not need to manually lift the vacuum pump, thereby effectively saving a lot of labor and not easily causing the vacuum pump to fall.

The top of one group of the lead screws 3 is also connected to a turning handle 12. The staff can control the rotation of one group of the lead screws 3 by holding the turning handle 12. During the rotation process, the group of lead screws 3 will drive the other group of lead screws 3 to rotate synchronously through the transmission action of the synchronous pulley 10 and the synchronous toothed belt 11.
