Among them, the output pressure of the hydraulic mechanism of the jacking device 70 is greater than the pressure of the hydraulic mechanism in the stacking device.

[0038] The stacking device is integrally slidably installed on the column 20, wherein the stacking device comprises a lower stacking assembly 40, an upper stacking assembly 50, a bottom bracket 10, a connecting bracket and a lifting assembly 30 installed on the bottom bracket 10, the connecting bracket fixedly connecting the upper stacking assembly 50 and the bottom bracket 10, and the output shaft of the lifting assembly connecting the lower stacking assembly 40.

[0040] The stacking device is used for stacking a plurality of oil carriers, wherein the oil carriers are disc-shaped or rectangular structures, and a clamping groove in a stepped or groove shape is arranged on the outer peripheral wall of the oil carrier.

[0041] The lower stacking assembly 40 comprises two groups, and the two groups of lower stacking assemblies 40 are oppositely arranged and slidably arranged on the column 20, forming an open entrance between the two groups of lower stacking assemblies 40, facilitating the oil carriers to be sent into the area between the two groups of lower stacking assemblies 40 from the entrance.

[0042] The lifting assembly 30 is installed on the bottom bracket 10, and the lifting assembly 30 is provided with two groups, and each lifting assembly 30 is connected to a corresponding lower stacking assembly 40.

The lower locking mechanism 42 is telescopically installed on the lower lifting bracket 41, and the two groups of lower lifting brackets 41 are oppositely arranged and used for clamping the opposite sides of the oil carrier. The lifting assembly 30 symmetrically pushes the lower stacking assembly 40, maintains the lifting movement of the oil carrier, and greatly improves the stability of the stacking.

[0044] It can be understood that the space between the two lower lifting brackets 41 is large, which can facilitate the movement and adjustment of the oil carrier.

[0045] The upper stacking assembly 50 is located above the lower stacking assembly 40, and the lower stacking assembly 40 moves up and down along the column 20. The upper stacking assembly 50 comprises an upper lifting bracket 51 and two groups of upper locking mechanisms 52 oppositely arranged, the upper lifting bracket 51 is in an integral template structure, preferably, the upper lifting bracket 51 is in a rectangular plate structure and is centrally hollowed out to allow the oil carriers to pass through.
