Detailed Description

The present invention is further described below with reference to fig. 1 to 3.

A jacking mechanism comprises a driving motor 5, a driving gear 1, a driven gear 2, a central shaft 4, two disc springs 6 and a bearing 7. The two ends of the rotating shaft 8 are respectively and fixedly provided with the flange plates 3, the rotating shaft 8 is sleeved with a bearing 7, and the rotating shaft 8 penetrates through the bearing 7 and rotates in the bearing 7. A hollow connecting cavity is arranged in the rotating shaft 8, the central shaft 4 penetrates through the connecting cavity and then is connected with the rotating shaft 8, and the rotating shaft 8 and the central shaft 4 rotate coaxially and synchronously. In order to drive the rotation shaft 8 to rotate, the driving end of the driving motor 5 penetrates through the shaft hole of the driving gear 1 and then is connected with the driving gear 1, the driven gear 2 is sleeved on the flange plate 3, the driving gear 1 is meshed with the driven gear 2, so that the driving motor 5 drives the driving gear 1, the driving gear 1 drives the driven gear 2, and the driven gear 2 drives the rotation shaft 8 to rotate. In order to realize the jacking function of the central shaft 4, the end surfaces of the two disc springs 6 are respectively attached to the end surfaces of the two flange plates 3 of the rotating shaft 8, the central shaft 4 penetrates through the two disc springs 6 and then is fixedly connected with the two disc springs 6, and when the central shaft 4 is driven to rotate by the rotating shaft 8, the disc springs 6 are radially deformed, so that the central shaft 4 is jacked in the vertical direction. In addition, in order to effectively protect the components such as the rotating shaft 8 and the like and play a role of supporting in the axial direction, a fixed shell is further arranged, the fixed shell is a cylindrical shell, the cylindrical shell is arranged between the two flange plates 3, a connecting support 9 is further arranged on the cylindrical shell, a connecting flange 10 is fixedly mounted on the driving motor 5, and the connecting support 9 is fixedly connected with the connecting flange 10 through screws.
