[0029] The two sets of limiting mechanisms are arranged at the bottom of the mounting rack assembly, and each set of limiting mechanism comprises a sliding beam 26 and a sliding groove plate 27. The sliding beam 26 is slidingly arranged between the two support rods 5 on the corresponding side. The sliding groove plate 27 is connected with the sliding beam 26. The sliding groove plate 27 is provided with a sliding groove 271 for the side of the sliding bracket 2 to slide into. One end of the sliding groove 271 is provided with an opening. When the side of the sliding bracket 2 slides into the limited position inside the sliding groove 271, the positioning hole 211 is aligned with the positioning column 3.

[0030] The power mechanism is arranged on the mounting rack assembly for driving the two sliding beams 26 to synchronously lift. The power mechanism comprises a rotating handle 22, a butterfly bolt 24, two transmission shafts 18, four winding discs 13 and four high-strength steel wire ropes 14. The rectangular frame 4 is provided with a rectangular groove 401. The two transmission shafts 18 are rotatably arranged at the two ends inside the rectangular groove 401. The two transmission shafts 18 are connected with a transmission assembly. The transmission assembly comprises a chain 20 and two sprockets 19. The two sprockets 19 are arranged on the two transmission shafts 18 respectively. The two sprockets 19 are connected with each other through the chain 20. Under the transmission of the transmission assembly, the two transmission shafts 18 can synchronously rotate. The four winding discs 13 are arranged at the two ends of the two transmission shafts 18 respectively. The ends of the four high-strength steel wire ropes 14 are fixedly arranged on the four winding discs 13 respectively. The end of the transmission shaft 18 on one side is movably arranged outside the rectangular frame 4 and connected with the rotating handle 22. The butterfly bolt 24 is threadedly connected with the rotating handle 22. The rectangular frame 4 is provided with a limiting hole for the end of the butterfly bolt 24 to rotate into. The four support rods 5 are vertically provided with sliding holes 501. The four sliding holes 501 are slidingly arranged with lifting seats 15 inside. The lifting seats 15 are connected with the high-strength steel wire ropes 14 on the corresponding side. The high-strength steel wire ropes 14 movably pass through the upper part of the support rod 5. The lifting seat 15 is provided with a clamping groove. The two ends of the sliding beam 26 are connected with clamping blocks 16. The clamping blocks 16 are arranged in the clamping grooves on the corresponding side.

[0031] The clamping groove inside the lifting seat 15 is provided with a buffer pad 17. The clamping block 16 is arranged on the buffer pad 17. The buffer pad 17 is arranged at the lower end of the clamping block 16, which can be used to buffer the vibration generated during the working process of the vacuum pump body 1.

[0032] The limiting frame 21 is connected with the fixed side plate 6. The limiting frame 21 is provided with a positioning hole 211 for the positioning column 3 to pass through.

[0033] Specifically, when installing the vacuum pump body 1, slide the mounting structure into the vacuum pump body 1 from one side, so that the vacuum pump body 1 is placed inside the mounting structure. Before installation, make sure the vacuum pump body 1 and the mounting structure are level. When moving the mounting structure, the sides of the two sliding brackets 2 at both ends of the bottom of the vacuum pump body 1 slide into the sliding grooves 271 on both sides respectively. When the mounting structure slides to the limited position, the positioning pin 3 is aligned with the positioning hole 211. Then, loosen the wing bolt 24 to release the limiting work on the rotating handle 22, and rotate the rotating handle 22. The drive shaft 18 on one side rotates, and with the cooperation of the transmission components, it drives the drive shaft 18 on the other side to rotate, thereby driving the four winding reels 13 to rotate synchronously. The rotation of the winding reels 13 winds up the high-strength steel wire rope 14, thereby driving the lifting seat 15 to move upward. The movement of the lifting seat 15 drives the movement of the sliding crossbeam 26 and the slide plate 27, realizing the lifting of the vacuum pump body 1. When the vacuum pump body 1 is lifted to the set height position, the butterfly bolt 24 is rotated so that its end is inserted into the limiting hole, thereby limiting the multiple winding reels 13.

[0034] Example 3

[0035] like Figure 4 As shown, this embodiment of the vacuum pump mounting structure, compared to Embodiment 2, features rotating feet 7 rotatably mounted on both ends of the fixed side plate 6. Rollers 8 are mounted on the rotating feet 7. A drive assembly for synchronously rotating the rotating feet 7 on both sides is mounted on the fixed side plate 6. The drive assembly includes a bidirectional lead screw 10, a knob 12, two rotating rods 9, and two connecting sliders 11. The bidirectional lead screw 10 is rotatably mounted on the sliding beam 26. The knob 12 is connected to the end of the bidirectional lead screw 10. Both connecting sliders 11 are slidably mounted on the sliding beam 26 and threadedly connected to the bidirectional lead screw 10. The two rotating rods 9 are rotatably connected to the connecting sliders 11 on both sides, and the other ends of the two rotating rods 9 are rotatably connected to the connecting sliders 11 on both sides. The movable support leg 7 is rotatably connected. When it is necessary to drive the vacuum pump body 1 to move, the knob 12 is used to drive the bidirectional lead screw 10 to rotate. Adjusting the rotation direction of the bidirectional lead screw 10 can drive the two connecting sliders 11 to move closer or further apart. By driving the two connecting sliders 11 to move further apart, with the cooperation of the rotating rod 9, the rotating support leg 7 can be driven to rotate until the rotating support leg 7 rotates to a vertical position. At this time, the roller 8 contacts the ground and the corresponding side support rod 5 is lifted. Then, adjust the two rollers 8 on the other side according to the above method. After moving the vacuum pump body 1 to the set position, drive the roller 8 to reset so that the bottom end of the support rod 5 contacts the ground, which helps to improve the stability of the vacuum pump body 1.

[0036] The embodiment of the utility model is described in detail above in combination with the drawings, but the utility model is not limited to this, and various changes can be made within the knowledge range possessed by the person skilled in the art without departing from the purpose of the utility model.
