[0002] Cold chain logistics is a special logistics method specifically used for transporting, storing, and distributing goods that need to be preserved in a constant or low temperature environment to ensure their quality, safety, and freshness. It is widely used in the fields of people's livelihood and medical care. In order to ensure the quality of cold chain goods and reduce the loss of cold chain goods, the goods need to be placed in insulated boxes during the transfer process, and then the insulated boxes are placed on the transfer platform for transfer to facilitate loading and unloading.

[0003] As disclosed in the prior art Chinese Patent Publication No. "CN218537432U", a cold chain logistics transfer rack includes a base plate, characterized in that: electric push rods are fixedly connected to the four upper corners of the base plate, square plates are fixedly connected to the push rod ends of each electric push rod, vertical blocks are fixedly connected to the square plates, symmetrical circular shafts are fixedly connected to the vertical blocks, symmetrical vertical grooves are fixedly connected to the vertical blocks, semi-circular grooves are fixedly connected to the symmetrical vertical grooves, circular arc grooves are fixedly connected to the vertical blocks, the symmetrical circular arc grooves are concentric with the corresponding semi-circular grooves, and transfer mechanisms are hinged to the symmetrical circular shafts.

[0004] Most existing cold chain warehouse loading and unloading platforms typically use support plates to support insulated boxes when transporting goods. However, the support plates cannot secure the insulated boxes, which means that if bumps or collisions occur during transportation, the insulated boxes can easily shift or even slip off the support plates, resulting in damage to the goods.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A cold chain warehouse loading and unloading platform includes a trolley 1. The upper end of the trolley 1 is provided with two oppositely arranged support plates 11. The upper surface of the trolley 1 is provided with a lifting assembly 2 for driving the support plates 11 to rise and fall. Each support plate 11 is provided with a clamping assembly 3. The lifting assembly 2 is provided with a synchronization assembly 4 for driving the clamping assembly 3 to move synchronously. A material unloading assembly 5 is provided on one side of the lifting assembly 2.

[0022] It should be noted that the lifting assembly 2 includes a mounting base 21 fixedly connected to the upper surface of the trolley 1, and a platform 22 disposed on the upper side of the mounting base 21. Both sides of the mounting base 21 are rotatably connected to a first connecting frame 23, and the free ends of the first connecting frame 23 are pinned to a connecting block 24. Both sides of the platform 22 are rotatably connected to a second connecting frame 25, and the free ends of the second connecting frame 25 are pinned to the connecting block 24. The first connecting frame 23, the second connecting frame 25, the mounting base 21, the platform 22, and the connecting block 24 are all fixed by pins.

[0023] In this embodiment, the lifting assembly 2 further includes a threaded rod 27 passing through the two connecting blocks 24 and a first motor 26 fixedly connected to one of the connecting blocks 24. The threaded rod 27 is threadedly connected to the connecting block 24 away from the first motor 24 and rotatably connected to the other connecting block 24. One end of the threaded rod 27 is fixedly connected to the shaft end of the first motor 26. The rotation of the shaft end of the first motor 26 causes the threaded rod 27 to rotate. Since the two connecting blocks 24 are rotatably connected to the threaded rod 27 and threadedly connected to it respectively, the rotation of the shaft end of the first motor 26 can move the two connecting blocks 24 away from or close to it, thereby moving the platform 22 up or down.

[0024] Furthermore, several support columns 12 and connecting rods 13 are fixedly connected to both sides of the upper side of the platform 22. The bearing plate 11 is fixedly connected to the support columns 12 and the platform 22 through the connecting rods 13. The support columns 12 support the bearing plate 11, and the connecting rods 13 form a triangular structure to increase the load-bearing capacity of the bearing plate 11.

[0025] The clamping assembly 3 includes a slider 31. A groove 14 is provided on the end face of the support plate 11. The slider 31 is slidably connected in the groove 14. A baffle 32 is fixedly connected to the upper side of the slider 31. The baffle 32 is slidably connected to the support plate 11. The groove 14 is a T-shaped groove, and the slider 31 is a T-shaped slider.

[0026] Furthermore, the synchronization component 4 includes a second motor 41 fixedly connected to the platform 22, and two opposing racks 42 slidably connected to the upper surface of the platform 22. The shaft end of the second motor 41 is fixedly connected to a gear 43, and both racks 42 mesh with the gear 43. One end of each rack 42 is fixedly connected to a rod 44, which is fixedly connected to the lower surface of the slider 31. The racks 42 and the platform 22 are slidably connected through guide grooves and guide blocks. The second motor 41 drives the gear 43 to rotate, and the rotation of the gear 43 drives the two racks 42 to move synchronously in opposite directions. The movement of the racks 42 drives the rod 44 to move, and the movement of the rod 44 drives the slider 31 to move. The movement of the slider 31 drives the baffle 32 to move synchronously.

[0027] Based on the above embodiments, the unloading assembly 5 includes a transport frame 51 rotatably connected between the two bearing plates 11 and an electric push rod 52 rotatably connected to one side of the platform 22. Several rollers 53 are rotatably connected inside the transport frame 51. The telescopic end of the electric push rod 52 is fixedly connected to one of the rollers 53. The electric push rod 52 pushes the transport frame 51 to rotate, thereby lifting the item. The item slides down through the roller 53 to unload.

[0028] Working method: When working, the items are placed in the insulated box, and then the insulated box is placed on the support plate 11. The second motor 41 is started, which moves the baffle 32 synchronously to center and clamp the insulated box. Then the trolley 1 is pushed to the unloading position. Then the first motor 26 is started to raise the support plate 11 to the appropriate position. The second motor 41 is started to reverse so that the clamping force of the baffle 32 on the items is loosened. Then the electric push rod 52 is started to raise the transport frame 51, so that the items can slide down safely.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
