In this embodiment, the lifting drive device 1 and the transverse drive device 2 are both controlled by electrical signals.

[0028] When the cargo is placed on the load-bearing device 4, the cargo can be lifted and moved horizontally by regulating the lifting drive device 1 and the horizontal drive device 2 to achieve mechanized lifting and moving of the cargo, and docking of the cargo with the container without changing the position of the bottom plate 3. The lifting drive device 1 and the horizontal drive device 2 can be regulated at the same time to further improve the efficiency of the docking action between the cargo and the container. Moreover, since rollers 5 are provided at the bottom of each lifting device, and the rollers 5 are placed on the flat bottom plate 3, the resistance to the horizontal movement of the lifting drive device 1 is greatly reduced. Therefore, only one horizontal drive device 2 is required to achieve the horizontal movement of the cargo, the load-bearing device 4 and all the lifting drive devices 1, effectively reducing the cost of the docking device. The bottom plate 3 described in this embodiment is fixed to the ground by bolts 15.

[0029] Specifically, in this embodiment, two lifting drive devices 1 are provided, and the transverse drive device 2 drives any one of the lifting drive devices 1 to move along the horizontal straight line where the two lifting drive devices 1 are located, so as to drive the goods, the carrying device 4 and all the lifting drive devices 1 to move transversely.

[0030] Specifically, the present embodiment further includes a support frame 12, a support frame 12 is fixed at the bottom of each lifting drive device 1, and all rollers 5 under each lifting drive device 1 are rotatably connected to their corresponding support frames 12. In the present embodiment, a plurality of rollers 5 are arranged at the bottom of each lifting drive device 1, and all rollers 5 are distributed in a rectangular array.

[0031] Specifically, the present embodiment further includes a transverse slide rail assembly 8 and a longitudinal slide rail assembly 9, and each lifting drive device 1 corresponds to a transverse slide rail assembly 8 and a longitudinal slide rail assembly 9; each transverse slide rail assembly 8 limits the horizontal linear movement of its corresponding lifting drive device 1 along the driving direction of the transverse drive device 2; the longitudinal slide rail assembly 9 is used to limit the vertical linear movement of the output end of its corresponding lifting drive device 1; the transverse slide rail assembly 8 and the longitudinal slide rail assembly 9 can effectively reduce the damage to the lifting drive device 1 and the transverse drive device 2 caused by the unbalanced loading of the cargo on the load-bearing device 4.

[0032] Specifically, the transverse slide rail assembly 8 includes two transverse fixed rails 81, and the two transverse fixed rails 81 are fixed on the bottom plate 3. The two side surfaces of the two transverse fixed rails 81 close to each other are provided with sliding grooves. The two sides of the support frame 12 are respectively inserted into the two sliding grooves, and the top walls of the two sliding grooves are located above the support frame 12 to ensure that the support frame 12 cannot detach from the transverse fixed rails 81 from above.

[0033] Specifically, the present embodiment further includes a safety limit plate 11, wherein two safety limit plates 11 are provided, both of which are fixed on the bottom plate 3, and all rollers 5 are located between the two safety limit plates 11, and the two safety limit plates 11 are used to limit the limit position of the horizontal linear movement of the rollers 5. The cooperation between the safety limit plate 11 and the transverse slide rail assembly 8 can hard limit the lifting drive device 1 on the bottom plate 3 in the event of electrical control failure, effectively preventing equipment damage and protecting the personal safety of the staff.

[0034] Specifically, the longitudinal slide rail assembly 9 includes a longitudinal fixed rail 91 and a longitudinal slide rail 92, both of which are cylindrical structures, and the longitudinal fixed rail 91 is sleeved on the outer side of the corresponding lifting drive device 1; the longitudinal slide rail 92 is sleeved on the outer side of the longitudinal fixed rail 91, forms a sliding connection with the longitudinal fixed rail 91, and is connected to the output end of the corresponding lifting drive device 1; all longitudinal slide rails 92 are connected to the bearing device 4. In this embodiment, a wear-resistant layer 93 is provided on the inner side of the longitudinal slide rail 92 to improve the service life of the longitudinal slide rail assembly 9. Through the nested cooperation of the longitudinal fixed rail 91 and the longitudinal slide rail 92, the protection effect of the lifting drive device 1 is further improved.

[0035] In this embodiment, the transverse drive device 2 and the lifting drive device 1 are both hydraulic cylinders. The piston rod and cylinder body of the transverse drive device 2 are hinged to the support frame 12 and the base plate 3 respectively, the cylinder body of the lifting drive device 1 is fixedly connected to the support frame 12, and the piston rod of the lifting drive device 1 is connected to the corresponding longitudinal slide rail 92.

[0036] This embodiment also includes a connecting frame 16 and a pin 10. A connecting frame 16 is fixed to the top of each longitudinal slide rail 92.

[0039] Specifically, when the output end of the lifting drive device 1 is at the initial position, the longitudinal proximity switch 7 does not send a signal. When the lifting drive device 1 is outputted longitudinally to a specified height, the longitudinal proximity switch 7 sends a lifting in place signal. The lifting drive device 1 can be shut down according to the number of times the lifting in place signal is received, so that the output end of the lifting drive device 1 stays at different heights. At the same time, the setting of the longitudinal proximity switch 7 can also effectively prevent damage to the lifting drive device 1 and reduce the occurrence of cargo hitting and injuring workers.

[0040] In this embodiment, the object detected by the longitudinal proximity switch 7 is a longitudinal sensing block 13 fixed on the longitudinal slide rail 92. When the longitudinal proximity switch 7 detects the longitudinal sensing block 13, the longitudinal proximity switch 7 sends a signal; when the longitudinal proximity switch 7 cannot detect the longitudinal sensing block 13, the longitudinal proximity switch 7 does not send a signal.

[0041] Specifically, when the output end of the transverse drive device 2 is at the initial position, the transverse proximity switch 6 does not send a signal.
