[0036] In the embodiment, the trolley 1 moves along the length direction of the X direction cross beams 6 on the lifting frame 2 through the X direction moving wheels 4, so as to realize the switching of the position on the X axis, the trolley 1 moves along the length direction of the Y direction longitudinal beams 7 on the lifting frame 2 through the Y direction moving wheels 5, so as to realize the switching of the position on the Y axis, through the switching of the switch, when the position on the X axis needs to be moved, the moving mode of the trolley 1 is switched to the X direction moving wheels 4, when the position on the Y axis needs to be moved, the moving mode of the trolley 1 is switched to the Y direction moving wheels 5, after the trolley 1 moves to the preset position, the lifting device can be used to lower the lifting rope 21, so that the hooks on the lifting rope 21 are lowered below the lifting frame 2 to hook the storage basket 3, so as to lift the storage basket 3 into the cavity 8, since the cavity 8 is arranged inside the trolley 1, the trolley 1 can be prevented from tilting, that is, the arrangement makes all the X direction moving wheels 4 on the trolley 1 evenly distributed on both sides of the center of gravity of the trolley, similarly, all the Y direction moving wheels 5 on the trolley 1 are evenly distributed on both sides of the center of gravity of the trolley, so that the storage basket 3 is not tilted after being lifted. Since the projection of the quadrilateral formed between any two adjacent X direction cross beams 6 and any two adjacent Y direction longitudinal beams 7 on the horizontal plane can surround the projection of the storage basket 3 on the horizontal plane, the X direction cross beams 6 and the Y direction longitudinal beams 7 are crossed to form a plurality of rectangular shapes on the horizontal plane, the rectangular shapes enable the lifting device to lift the storage basket 3 to the lifting frame 2. Since the storage basket 3 can be completely located in the cavity 8 when the lifting device lifts the storage basket 3 into the cavity 8, the storage basket 3 can be completely hidden in the cavity 8 after being lifted into the cavity 8, so as to avoid the lower end of the storage basket 3 from being bumped against the Y direction longitudinal beams 7 or the X direction cross beams 6 to affect the movement of the trolley 1.

[0037] As a preferred mode, the switch comprises a lifting device and a moving frame, the moving frame is fixedly arranged on the trolley 1 through the lifting device, and the Y-direction moving wheel 5 is arranged on the moving frame. When the moving frame is lowered under the action of the lifting device, the lowermost end of the Y-direction moving wheel 5 is lower than the lowermost end of the X-direction moving wheel 4. When the moving frame is raised under the action of the lifting device, the lowermost end of the X-direction moving wheel 4 is lower than the lowermost end of the Y-direction moving wheel 5. The moving frame is provided with a passage 11 matched with the cavity 8. After the lifting device drives the moving frame to rise, the Y-direction moving wheel 5 is suspended, so that the Y-direction moving wheel 5 does not contact the Y-direction longitudinal beam 7. At this time, the X-direction moving wheel 4 contacts the X-direction cross beam 6, and the trolley 1 moves along the length direction of the X-direction cross beam 6. The Y-direction moving wheel 5 does not affect the movement of the trolley 1 along the length direction of the X-direction cross beam 6. Conversely, when the lifting device drives the moving frame to descend, the X-direction moving wheel 4 is suspended, so that the X-direction moving wheel 4 does not contact the X-direction cross beam 6. At this time, the Y-direction moving wheel 5 contacts the Y-direction longitudinal beam 7, and the trolley 1 moves along the length direction of the Y-direction longitudinal beam 7. The X-direction moving wheel 4 does not affect the movement of the trolley 1 along the length direction of the Y-direction longitudinal beam 7. The passage 11 is arranged to position the cavity 8, so as not to affect the lifting of the storage basket 3 by the lifting device.

[0038] Specifically, the X-direction moving wheel 4 is arranged on the front side wall and the rear side wall of the trolley 1. The moving frame comprises a bottom plate 9 and an ear plate 10. The ear plate 10 is arranged at the left and right ends of the bottom plate 9. The passage 11 is arranged on the bottom plate 9. The Y-direction moving wheel 5 is arranged on the two ear plates 10. The wheel shaft of the Y-direction moving wheel 5 is perpendicular to the wheel shaft of the X-direction moving wheel 4.

[0039] As a preferred mode, the lifting device comprises four lifting units, which are uniformly distributed around the passage 11. After such arrangement, the stress balance during the lifting of the moving frame can be ensured, and the lifting device does not affect the lifting of the storage basket 3 into the cavity 8 by the lifting device.

[0040] As a preferred mode, the lifting device further comprises a first driving motor 12 and a synchronous transmission device. The output end of the first driving motor 12 is connected to the four lifting units through the synchronous transmission device. In this way, four lifting units are connected through one synchronous transmission device, which is convenient for control compared with the case that each lifting unit is provided with a first driving motor 12. At the same time, the overall weight of the trolley 1 can be reduced, and the cost can be saved.

[0041] As a preferred mode, the lifting unit comprises a base 13, a lead screw 22, a top column 14, a drive nut 15, the top column 14 is fixedly connected to the lower surface of the bottom plate 9, the base 13 is provided with an upwardly open mounting cavity, the drive nut 15 is coaxially arranged on the top of the mounting cavity of the base 13, the top end of the lead screw 22 is rotatably connected to the top column 14, the drive nut 15 is threadedly connected between the two ends of the lead screw 22, and the drive nut 15 is drivingly connected to the transmission output end of the synchronous transmission device.

The connecting line segments between the two second gears 33 and the first gears 32 are located on the same plane parallel to the upper surface of the base 13. The included angle between the two connecting line segments is ninety degrees. The lengths of the two connecting line segments are equal. Four bases 13 are respectively located at the four vertices of a virtual rectangle. One transmission rod 16 is arranged on each of the three sides of the virtual rectangle. The first bevel gears 17 at the two ends of the transmission rod 16 mesh with a second bevel gear 18 on the base 13.

The output shaft of the first driving motor 12 is drivingly connected to the driving rod 19. After the above arrangement, the first driving motor 12 drives the driving rod 19 to rotate. The first bevel gear 17 on the driving rod 19 drives the second bevel gear 18 on one of the lifting units to rotate, and at the same time, the second gear 33 on the lifting unit rotates. The rotation of the second gear 33 drives the first gear 32 to rotate. The rotation of the first gear 32 drives the drive nut 15 on the lifting unit to rotate, and then drives the lead screw 22 on the lifting unit to move up and down. The transmission between the lifting units is achieved through the transmission rods 16 and the first bevel gears 17 and the second bevel gears 18 between the lifting units. The transmission rods 16 and the driving rod 19 enclose the cavity 8, that is, the projection of the cavity 8 in the plane is located in the virtual rectangle, so that the purpose of transmission is achieved, and the lifting device can lift the storage basket 3 into the cavity 8 without affecting the lifting device.
