[0026] Referring to Figures 1-4 The heavy load jacking mechanism provided by the present application comprises two frames 1 which are symmetrically arranged on both sides of the mounting seat 2, and a worm gear lifting mechanism 6 is fixedly installed inside each end of the frame 1. A second transmission assembly 5 is arranged between the front and rear worm gear lifting mechanisms 6, and the second transmission assembly 5 is used to make the two worm gear lifting mechanisms 6 work synchronously. The top of the worm gear lifting mechanism 6 is fixedly connected with a supporting plate 7. The upper end of the mounting seat 2 is fixedly connected with a speed reducer motor 3, and the two output ends of the speed reducer motor 3 are provided with a first transmission assembly 4. The speed reducer motor 3 is connected with the power end of the worm gear lifting mechanism 6 through the first transmission assembly 4.

[0027] In use, the frame 1 and the mounting seat 2 are fixed at the end of the conveying line respectively. When the tray is conveyed to the upper end of the supporting plate 7 together with the robot, the speed reducer motor 3 works. Under the cooperation of the first transmission assembly 4 and the second transmission assembly 5, the four worm gear lifting mechanisms 6 can work synchronously. In this way, the two supporting plates 7 on both sides can be driven to move upward synchronously, and the tray at the upper end of the supporting plate 7 can be moved upward by a certain height. In this way, the AGV trolley can be conveniently carried out.

[0028] The first transmission assembly 4 comprises first couplings 401 and a first rotating shaft 402, both ends of the first rotating shaft 402 are fixedly connected with the first couplings 401, and the two first couplings 401 are connected with the output end of the speed reducer motor 3 and the power end of the worm gear lifting mechanism 6 respectively. The second transmission assembly 5 comprises second couplings 501 and a second rotating shaft 502, both ends of the second rotating shaft 502 are fixedly connected with the second couplings 501, and the two second couplings 501 are connected with the power end of the two worm gear lifting mechanisms 6 respectively. When working, the speed reducer motor 3 works, at this time, the first rotating shaft 402 can be driven to rotate under the cooperation of the first couplings 401, and then the second rotating shaft 502 is driven to rotate under the cooperation of the second couplings 501, so that the four worm gear lifting mechanisms 6 can work synchronously
