[0036] Embodiment 2

[0037] See also Figure 1-7 , and on the basis of the first embodiment, the clamping mechanism 4 further comprises a third annular slide groove 44, the third annular slide groove 44 is opened on the outside of the placement table 3, the top of the placement table 3 is fixedly connected with a motor 45, the top of the motor 45 is fixedly connected with a rotating shaft 402, the upper surface of the rotating shaft 402 is fixedly connected with a gear 403, the surface of the gear 403 is meshedly connected with an annular gear ring 404, the outer side of the annular gear ring 404 is fixedly connected with a mounting plate 41, the bottom of the mounting plate 41 is fixedly connected with a second annular slider 42, the outer side of the annular gear ring 404 is fixedly connected with a mounting seat 43, the top of the placement table 3 is opened all around A T-shaped slot 48 is provided, and a T-shaped block 47 is slidably connected inside the T-shaped slot 48. A long seat 401 is fixedly connected to the top of the T-shaped block 47. A clamping plate 49 is fixedly connected to the side of the long seat 401 away from the motor 45. A hinged plate 46 is hinged on the side of the long seat 401 close to the annular gear ring 404. The other side of the hinged plate 46 is hinged to the inner side of the annular gear ring 404. There are four second annular sliders 42. The surface of the second annular slider 42 is slidably connected to the inside of the third annular slide groove 44. There are four mounting seats 43. The four mounting seats 43 are all arranged on one side of the four mounting plates 41. The mounting seats 43 are arranged on the top of the placement table 3.

[0038] Furthermore, the motor 45 drives the rotating shaft 402 to rotate, and the rotating shaft 402 can also drive the gear 403 to rotate. The annular gear ring 404 can rotate in a circle around the gear 403. When the annular gear ring 404 rotates, the second annular slider 42 can also slide in the third annular slot 44. When the annular gear ring 404 drives the mounting seat 43 to rotate, the long seat 401 can also move. When the long seat 401 moves, it can also drive the T-block 47 to slide in the T-slot 48. At the same time, the long seat 401 drives the clamping plate 49 to fix the position of the Roots pump, which is convenient for the later maintenance of the Roots pump.

[0039] In actual operation, when the device is used, when the Roots pump is placed on the placement table 3, the motor 45 is started, the motor 45 drives the rotating shaft 402 to rotate, and the rotating shaft 402 can also drive the gear 403 to rotate. Since the gear 403 and the annular gear ring 404 are meshed and connected, the annular gear ring 404 can rotate in a circle around the gear 403. When the annular gear ring 404 rotates, the second annular slider 42 can also slide in the third annular slot 44. At the same time, since the hinged plate 46, the mounting seat 43 and the long seat 401 are hinged, when the annular gear ring 404 drives the mounting seat 43 to rotate, the long seat 401 can also move. When the long seat 401 moves, it can also drive the T-block 47 to slide in the T-slot 48. At the same time, the long seat 401 drives the clamping plate 49 to fix the position of the Roots pump, which is convenient for the later maintenance of the Roots pump.

[0040] When the Roots pump needs to be repaired, the Roots pump needs to be transported and replaced, and the Roots pump can also be repaired during transportation. When the Roots pumps on different surfaces need to be repaired, the placement table 3 can be rotated so that the placement table 3 drives the rotating rod 5 to rotate on the top of the base 1. Since the first inclined plate 213 is fixed between the connecting block 212 and the fixing seat 214, when the rotating rod 5 rotates, it drives the connecting seat 211 to rotate, and at the same time, the connecting seat 211 drives the second inclined plate 218 to rotate. When the second inclined plate 218 rotates, it can also drive the connecting plate 217 to rotate. The connecting plate 217 drives the first annular slider 216 to drive the first annular slider 216 to slide in the first annular slide groove 215, which can make the placement table 3 more stable when rotating, and at the same time, it can avoid the maintenance personnel walking to repair different surfaces of the Roots pump, and can directly stand in the original place to repair the Roots pump;

[0041] When the electric push rod 224 is started, the electric push rod 224 drives the long block 228 to be inserted into the long groove 227, and the slide groove 229 is inserted and slid in the slider 222, so that the position of the placed table 3 can be limited and fixed after rotation, so that when the Roots pump placed on the placed table 3 is repaired, the placed table 3 will not rotate at will.
