[0014] Attachment Figure 2 It is a structural diagram of the cargo platform and lifting mechanism. DETAILED DESCRIPTION

[0015] The present invention is described in detail below with reference to the embodiments shown in the accompanying drawings:

[0016] like Figure 1 As shown, the stacking system with a shared loading platform and lifting mechanism includes a crane 0, shelves forming a plurality of aisles, a loading platform 5 installed on the crane and capable of moving up and down, a lifting mechanism 6 installed on the crane for driving the loading platform 5 to move up and down, and movable column assemblies arranged in each aisle. The shelves are not shown in the figure, and a row of shelves is provided between two adjacent column assemblies, that is, each column assembly is located in an aisle.

[0017] The crane includes a traveling track 1 extending along the Y direction, a traveling beam 21 erected on the traveling track along the X direction perpendicular to the Y direction, a Y-direction wheel set 22 provided on the traveling track and supported under the traveling beam for driving the traveling beam 21 to move along the Y direction, a Y-direction traveling motor 23 for driving the Y-direction wheel set 22 to move, and an overhead crane 4 that can move on the traveling beam along the X direction. The lane extends along the Y direction, and the lifting mechanism 6 and the cargo platform 5 are installed on the overhead crane 4.

[0018] Specifically, the column assembly 7 includes a column body 71, a column walking mechanism 72 provided on the lower end of the column body 71, and a column guide mechanism 73 provided on the upper end of the column and supported between the shelves. The cargo platform 5 includes a cargo shelf 51, a cargo guide mechanism 52 installed on the cargo shelf 51, and a sleeve mechanism 53 installed on the overhead crane 4. When the sleeve mechanism 53 is suspended directly above one of the column bodies 71, after the cargo shelf 51 descends, the sleeve mechanism 53 descends accordingly and is sleeved on the upper end of the column body 71, so that the overhead crane 4 and the column body 71 are relatively fixed in the horizontal direction, and the cargo guide mechanism 52 is docked with the column body 71 so that the cargo shelf 51 can move up and down along the column body 71.

[0019] The overhead crane 4 includes an overhead crane frame 41 hung on the traveling beam 21, overhead crane running wheels 42 rotatably connected to the overhead crane frame 41 and located on the traveling beam 21, an overhead crane drive motor 43 mounted on the overhead crane frame 41 and driving two of the overhead crane running wheels 42 to rotate via a connecting shaft 45, and an overhead crane reducer 44 connected between the overhead crane drive motor 43 and the overhead crane running wheels 42. The overhead crane drive motor 43 drives the overhead crane frame 41 to move along the X direction on the traveling beam 21.

[0020] The lifting mechanism 6 includes a lifting motor 61 fixedly mounted on the overhead crane 4, a winding drum 63 which is transmission-connected to the lifting motor 61 via a lifting reducer 62, a lifting guide wheel 64 which is rotationally connected to the overhead crane 4 and the cargo platform 5, and a steel wire rope 65 whose one end is fixed and wound around the winding drum 63 and then passes around the lifting guide wheel 64 and the other end is fixed to the overhead crane 4.

[0021] The column walking mechanism 72 includes a walking support tube 721 vertically fixed on the lower end of the column body 71, a walking wheel 722 rotatably connected to the walking support tube 721 and partially exposed below the lower end surface of the walking support tube 721, and a column walking motor 723 for driving the walking wheel 722 to rotate.

[0022] The column guide mechanism 73 includes a column guide bracket 731 extending from the side of the column body 71 along the X direction toward the shelf, and a column guide wheel 732 rotatably connected to the column guide bracket, and the wheel surface of the column guide wheel presses on the shelf.

[0023] The sleeve mechanism 53 includes a guide rod 531 fixed on the overhead crane 4 and arranged vertically on the ground, a synchronization sleeve 532 mounted on the guide rod and capable of being mounted on the column body 71, a column guide rail 711 is provided on the front side of the column body 71, and a blocking protrusion 712 is provided on the rear side to prevent the synchronization sleeve from continuing to fall after being inserted into the column body 71. The cargo guide mechanism 52 includes a cargo guide sleeve 521 with a guide groove matching the column guide rail 711. The cargo guide sleeve 521 is fixed on the outer wall of the cargo carrier 51 and is provided with a lifting rod 522 for lifting the synchronization sleeve and completely separating it from the column body 71 when rising. The column guide bracket 731 is set against the rear side of the column body 71, and the blocking protrusion 712 is located on the rear side of the column body 71. The lifting rod 522 is fixed to the lower end of the cargo guide sleeve 521 and goes around from the left and right sides of the column body to the rear side of the column body without closing, which not only ensures that it can interfere with the synchronization sleeve 532 but also ensures that it does not interfere with the blocking protrusion 712.

[0024] The principle of the present invention is as follows: Figure 2As shown, the Y-axis wheel group 22 drives the traveling beam 21 to move along the Y direction under the drive of the Y-axis traveling motor 23, and the overhead crane drive motor 43 drives the overhead crane traveling wheel 42 to rotate, thereby driving the overhead crane to move along the X direction on the traveling beam 21. When the sleeve mechanism 53 moves with the overhead crane 4 to the top of the column body 71, the lifting mechanism 6 releases the loading platform 5, and the loading guide sleeve is first inserted into the column guide rail, and the synchronous sleeve then descends until it is blocked by the blocking protrusion. At this time, the synchronous sleeve is simultaneously sleeved on the guide rod and the column body 71, so that the column body 71 can move with the overhead crane 4, and the loading platform 51 continues to descend to the loading and unloading position. After completing the loading and unloading action, the overhead crane 4 drives the column assembly 7 to reset, and then the loading platform 51 moves upward until the lifting rod contacts the synchronous sleeve, and then the synchronous sleeve is lifted until the synchronous sleeve and the loading guide sleeve are completely separated from the column body 71. At this time, the overhead crane 4 can move to the column assembly 7 in other lanes for loading and unloading operations.
