[0055] Furthermore, two hooks 27 are provided on the frame 20 a , and the two hooks 27 can be located on the top of the first bracket 22 and the second bracket 23 respectively, for lifting the loading and unloading basket 20 .

[0056] The main frame 10 is also topped with a hanger 12. Sliding grooves 13 are provided on two opposing inner sides of the hanger 12. The sliding mechanism 90 comprises a sliding frame 91 and a sliding drive 92. The two sides of the sliding frame 91 slide in engagement with the two sliding grooves 13. The sliding drive 92 is mounted on the hanger 12 and is connected to drive the sliding frame 91 outward or inward relative to the hanger 12. The interactive drive 92 can be a pneumatic cylinder.

[0057] The hoisting mechanism 43 is mounted on the sliding frame 91 of the main frame 10 and is connected to drive the loading and unloading basket 20 to rise or fall.

The drum is mounted on the sliding frame 91. One end of the two steel wire ropes 44 can be provided with a hook, which is connected to the hook 27 on the frame 20a through the hook. The other end is fixedly wound around the drum. The motor drives the drum to rotate forward or reverse, driving the steel wire ropes 44 to lift or lower the frame 20a. When the sliding frame 91 slides relative to the hanger 12, it can drive the loading and unloading basket 20 to move outward to the outside of one end of the main frame 10 or inward to one end of the layer 11.

[0058] Furthermore, in order to ensure the reliability and safety of the movement of the frame 20a, the present invention also includes at least one slide rail group, one end of which is rotatably connected to the sliding frame 91 of the sliding mechanism 90. At least one frame 20a is in sliding cooperation with the corresponding slide rail group.

[0059] The conveyor mechanism 50 is mounted on one end of the deck 11 to transport large ice cubes between the deck 11 and the loading and unloading basket 20. The conveyor mechanism 50 can be implemented using a common roller structure and may include a mounting frame 51, a plurality of rollers 52, a transmission belt, and a motor. The plurality of rollers 52 are rotatably mounted on the mounting frame 51 and are provided with a transmission wheel 53. The motor output shaft is provided with a driving wheel, and the transmission belt is wound between the driving wheel 53 and the driving wheel to transmit power. When the motor drives the driving wheel to rotate, the transmission belt drives the rollers 52 to roll, thereby driving the large ice cubes 80. The movement direction of the large ice cubes 80 is related to the rotation direction of the rollers 52, which is determined by the rotation direction of the driving wheel.

[0060] The push mechanism 60 is mounted on the main frame 10 and is used to push the large ice blocks 80. It comprises a first push rod 61, a second push rod 62, and a drive assembly. The drive assembly drives the first push rod 61 inward to push the large ice blocks 80 onto the shelf 11 for loading.

The transmission rod 64 is equipped with a driving gear 67, and its ends are respectively connected to the two conveyor belt assemblies. A first push rod 61 and a second push rod 62 are connected between the two conveyor belt assemblies. The drive motor 63 is connected to the driving gear 67 to rotate, thereby driving the conveyor belt assemblies to drive the first push rod 61 and the second push rod 62 to move. The two conveyor belt assemblies are respectively located on both sides of the large ice block 80 near the top, with a certain distance between the first push rod 61 and the second push rod 62. The first push rod 61 and the second push rod 62 are arranged so that when the first push rod 61 is located at one end of the shelf 11, the second push rod 62 is located at the other end of the shelf 11.

[0062] Furthermore, the conveyor belt group includes a conveyor belt 65 and a plurality of gears 66. The plurality of gears 66 can be arranged along the length and height of the main frame 10 and are rotatably connected to the main frame 10. That is, the gears 66 are arranged in the length and width directions of the main frame 10. The number of gears 66 can be set according to the length and height of the main frame 10 and is not limited here.

The second push rod 62 is also connected between the conveyor belts 65 of the two conveyor belt groups and can move along the length or height direction of the main frame 10 with the conveyor belts 65.

[0063] For further information, see Figure 6 At least one buffer assembly 70 is also provided at the other end of the shelf 11. The buffer assembly 70 includes a buffer plate 71, at least one elastic member 72, and at least one connecting shaft 73. One end of the connecting shaft 73 is fixedly connected to the corresponding end of the main frame 10. The buffer plate 71 is slidably mounted on the other end of the connecting shaft 73. The elastic member 72 is disposed between the corresponding end of the main frame 10 and the buffer plate 71, preventing large ice cubes 80 from directly impacting the main frame 10 and providing a buffering effect.

[0064] In the present invention, the main frame 10 may include two upper and lower decks 11, each deck 11 having two conveyor mechanisms 50 disposed on one end and two pusher mechanisms 60 disposed on the upper end. The two conveyor mechanisms 50 and the two pusher mechanisms 60 may operate synchronously, thereby enabling simultaneous loading and unloading of two groups of large ice cubes 80. Accordingly, the main frame 10 may include two lifting mechanisms 43 and two loading and unloading baskets 20, the two lifting mechanisms 43 being disposed on the left and right sides, and the two loading and unloading baskets 20 also being disposed on the left and right sides and facing the corresponding conveyor mechanisms 50, thereby enabling simultaneous loading and unloading of two groups of large ice cubes.

[0065] The transport vehicle of the present invention may also be equipped with a main control device for controlling the coordinated operation of the various modules to achieve automatic loading and unloading. The main control device may be connected to the first roller assembly 30, the rotation drive device, the sliding drive device 92, the lifting mechanism 43, the conveying mechanism 50, the drive motor 63 of the pushing mechanism 60, and the like. The main control device may utilize a 1215C CPU, model 6ES7215-1AG40-0XB0.

[0066] In normal state, the main frame 10 does not contain large ice cubes 80. The first push rod 61 is located at one end of the shelf 11 and is located near the middle between the two shelves 11. The second push rod 62 is located at the other end of the shelf 11 and can be located near the top between the two shelves 11. After the slide rail group is folded, it is stored in a suitable position at the top of the main frame. The two loading and unloading baskets are located at the conveying mechanism of the upper shelf.

[0067] Before loading, the door of the vehicle body 10a is opened, and the sliding drive device 92 controls the sliding frame 91 to extend outward, and the slide rail assembly is unfolded and fixed to the fixing frame 47, and the frame 20a is slidably engaged with the slide rail assembly. The hoisting mechanism 43 is controlled to operate and drive the loading and unloading basket 20 to the ground to facilitate the loading of large ice cubes. Figure 1 、 Figure 2 .

[0068] When loading large ice cubes 80 onto the main frame 10, first load the large ice cubes 80 onto the lower shelf 11, and proceed as follows:

[0069] Open the barrier bars 24 of the two loading and unloading baskets 20, move a certain number of large ice cubes 80 into the frame 20a, and then lower the barrier bars 24; then control the driving motors 63 of the two pushing mechanisms 60 on the lower layer to reverse and move the first push rod 61 upward, and at the same time control the two lifting mechanisms 43 to work and lift the two frames 20a to the height of the lower layer's shelf 11 and then stop. Figure 12, then control the rotary drive device to drive the second roller assembly 40 to rotate so that it is flush with the first roller assembly 30 and the layer 11, and then control the rolling drive device to work, driving the first roller 31 on the first fixed frame 32 to roll, and the large ice cubes 80 in the frame 20a are moved to the conveying mechanism 50 on the layer 11 via the second roller 41 of the second fixed frame 42. The driving motor 63 of the two pushing mechanisms 60 is controlled to rotate forward so that the first push rod 61 moves downward to its position, and then moves inward to push the large ice cubes 80 of the group, and cooperates with the conveying mechanism 50 to transport the large ice cubes 80 to the layer 11 until the large ice cubes 80 of the group leave the conveying mechanism 50. Figure 13 .

[0070] Afterwards, the second roller assembly 40 is driven back to its original position, and the loading and unloading basket 20 is controlled to descend and hoist the second group of large ice blocks 80. The process is the same as above, see Figure 14 The current group of large ice cubes 80 on the conveying mechanism 50 can push the previous group of large ice cubes 80 to move one group of large ice cubes 80 to the other end of the shelf 11, until the first group of large ice cubes 80 contacts the buffer assembly 70, and the shelf 11 is full. Figure 15 At this time, the last group of large ice cubes 80 can be located above the conveying mechanism 50, and the two first push rods 61 are located near the middle of the large ice cubes 80 of this group, which can prevent them from moving outward.

[0071] Then, large ice blocks 80 are loaded onto the upper layer plate 11 in the same manner as the lower layer, see Figure 16 、 Figure 17 Until the upper layer is full. If the upper layer is not full, the first push rod 61 can also be located near the middle of the last group of large ice cubes 80 to block the group of large ice cubes 80 and prevent them from sliding relative to each other. Then, the slide rails 45 of the slide rail assembly are folded or disassembled and installed in the appropriate position in the vehicle body 10a. The sliding drive device 92 controls the sliding frame 91 to move inward, driving the loading and unloading basket 20 to move to the upper conveying mechanism 50. The vehicle door can then be closed for transportation. Figure 18 .

[0072] To unload large ice cubes 80 from the main frame 10, the door of the vehicle body 10a is opened. The sliding drive device 92 controls the sliding frame 91 to extend outward, the rail assembly is deployed or installed, and then secured to the fixed frame 47. The frame 20a and the rail assembly are then slidably engaged. The hoisting mechanism 43 is then activated to lower the loading and unloading basket 20 to the ground. The ice cubes are then unloaded from the lower shelf 11. The operation is as follows:

[0073] The two lifting mechanisms 43 are controlled to work to lift the two loading and unloading baskets 20 to the height of the lower layer's shelf 11 and then stop. The rotary drive device is controlled to drive the second roller assembly 40 to rotate so that it is flush with the first roller assembly 30 and the shelf 11. Then, the rolling drive device is controlled to work to drive the first roller 31 on the first fixed frame 32 to roll. The conveying mechanism 50 of the lower layer is controlled to work, and the drive motors 63 of the two pushing mechanisms 60 are reversed to make the first push rod 61 move upward. At this time, the second push rod 62 moves downward and pushes all the large ice cubes 80 on the shelf 11. The large ice cubes 80 on the outermost group can be pushed onto the conveying mechanism 50, and cooperate with the conveying mechanism 50 to enter the first roller assembly 30 through the second roller assembly 40. Then, the second roller assembly 40 is controlled to return to its position, the loading and unloading basket 20 descends, and the barrier bar 24 is opened to unload the large ice cubes 80 in this group.

[0074] Then, the loading and unloading basket 20 is controlled to rise and continue to unload the second group of large ice cubes 80. The driving motor 63 of the pushing mechanism 60 continues to work, and the large ice cubes 80 on the layer 11 can be pushed outward, input into the conveying mechanism 50 in turn, and then unloaded, until all the large ice cubes 80 on the layer 11 are unloaded, that is, the unloading of this layer is completed.

[0075] Afterwards, the large ice blocks 80 on the upper layer plate 11 are removed in the same manner to complete the unloading.

[0076] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
