[0021] The following will be combined with the attached embodiment of the present invention Figure 1-9, clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] The present application discloses an automated plasma box transport vehicle, such as Figure 1-Figure 9 As shown, it includes a carriage 1, which can be used to accommodate plasma boxes. By setting up a closed carriage 1, it can be avoided that plasma transportation cannot be carried out due to light avoidance and temperature not meeting requirements under extreme weather conditions; and the wall of the carriage 1 is a hollow structure, which is filled with thermal insulation material, thereby facilitating better heat isolation and improving the thermal insulation effect of the carriage 1.

[0023] An inlet and outlet 11 is provided at the rear of the carriage 1, and an air curtain machine 12 is provided at the inlet and outlet 11. The air curtain machine 12 can generate a strong airflow at the inlet and outlet 11, thereby forming an air valve curtain at the inlet and outlet 11. In this way, the inlet and outlet 11 of the carriage 1 can be isolated, which can not only separate the air and dust inside and outside the carriage 1, but also prevent the exchange of cold and hot air inside and outside the carriage 1, thereby improving the thermal insulation effect of the carriage 1.

[0024] A tailgate is provided at the inlet and outlet 11, and the setting of the tailgate can facilitate the opening or closing of the inlet and outlet 11, so as to facilitate the transportation of the plasma box. Moreover, the tailgate is a double-opening insulation door, so when the tailgate is closed, it can be beneficial to the insulation of the carriage 1.

[0025] The carriage 1 is provided with a receiving chamber 13, and the receiving chamber 13 is provided with a conveying device 3 for moving the pallet 2 from the entrance 11 to the inside of the carriage 1. With the help of the conveying device 3, the pallet 2 stacked with plasma boxes can be moved in or out of the carriage 1. In this way, during the loading and unloading process, a forklift can be directly used to operate the pallet 2 at the entrance 11, thereby connecting the height difference between the carriage 1 and the ground by using the forklift for loading and unloading, which can reduce the difficulty of the operation. In addition, the pallet 2 can be directly transported by the conveying device 3 during the transportation process inside the carriage 1, without the need for loading and unloading personnel to load and unload in the carriage 1, which reduces the labor intensity of transportation and also improves the efficiency of transportation.

[0026] In this embodiment, the conveying device 3 is arranged along the length direction of the carriage 1. In this way, the conveying device 3 is always arranged in the carriage 1. When loading, the conveying device 3 can translate the pallet 2 stacked with plasma boxes from the entrance and exit 11 to the inside of the carriage 1; when unloading, the conveying device 3 can translate the pallet 2 stacked with plasma boxes from the inside of the carriage 1 to the entrance and exit 11, thereby realizing smooth and convenient transportation of the pallet 2.

[0027] Limiting plates 4 for limiting the two sides of the tray 2 are correspondingly provided on both sides of the top of the conveying device 3. When the conveying device 3 transports the tray 2, the limiting plates 4 will limit the position of the two sides of the tray 2 to prevent the tray 2 from sliding during the transportation process of the conveying device 3, and can protect the plasma boxes stacked on the top of the tray 2 to prevent the plasma bags in the plasma boxes from shaking and being damaged.

[0028] Moreover, the position of the limit plate 4 relative to the top edge of the conveying device 3 can be adjusted by the adjustment device 5. In this way, the position of the limit plate 4 can be adjusted according to pallets 2 of different sizes, which is suitable for conveying pallets 2 of various sizes and can be suitable for various conveying environments.

[0029] A fixing device 6 for fixing both sides of the pallet 2 is provided on the top of the conveying device 3. The fixing device 6 can position and clamp both sides of the pallet 2 to prevent the pallet 2 from shifting during transportation, thereby preventing the plasma bag in the plasma box from being bumped and damaged during transportation, thereby reducing the rupture of the plasma bag.

[0030] A temperature control device 7 is provided above the carriage 1, and the temperature inside the carriage 1 can be controlled by the temperature control device 7, thereby better meeting the requirements of plasma transportation.

[0031] Specifically, the conveying device 3 includes a conveying frame 31 arranged along the length direction of the carriage 1, and the conveying frame 31 is correspondingly arranged on both sides of the carriage 1, and the conveying frames 31 on both sides of the carriage 1 are fixedly connected by a connecting frame 32; and an active conveying roller 33 and a driven conveying roller 34 are provided between the conveying frames 31 on both sides of the carriage 1, and the active conveying roller 33 and the driven conveying roller 34 can rotate relative to the conveying frame 31.

[0032] The active conveying roller 33 and the driven conveying roller 34 are provided with a conveying sprocket 35 on the same side, and the conveying sprocket 35 on the same side of the active conveying roller 33 and the driven conveying roller 34 is provided with a transmission chain; the transmission chain is respectively wrapped around all the conveying sprockets 35 on the same side to form an annular closed structure connected end to end, so that the active conveying roller 33 can synchronously drive several driven conveying rollers 34 to rotate synchronously, and the pallet 2 on the conveying device 3 can be translated from the entrance and exit 11 to the inside of the carriage 1; the pallet 2 can also be translated from the inside of the carriage 1 to the entrance and exit 11, so as to realize the function of fast loading and unloading of vehicles.

[0033] Specifically, a driven fixed column 311 is fixedly provided between the conveying frames 31 on both sides, and a driven conveying roller 34 is provided on the outer sleeve of the driven fixed column 311, and the driven conveying roller 34 can rotate relative to the driven fixed column 311; an active fixed column 312 is movably provided between the conveying frames 31 on both sides, and both ends of the active fixed column 312 are movably connected to the conveying frames 31 through bearings 313, and the active conveying roller 33 is nested outside the active fixed column 312; a conveying motor 315 is fixedly provided on the side of the conveying frame 31 through a motor plate 314, and the output end of the conveying motor 315 is transmission-connected to the input end of the active fixed column 312.

[0034] Specifically, an opening 316 is provided at the front end of the conveying frame 31, and the pallet 2 can be placed on the active conveying roller 33 and the driven conveying roller 34 through the opening 316 provided at the front end, and a baffle 317 is provided at the rear end of the conveying frame 31 to limit the pallet 2. When the pallet 2 moves to the innermost part of the carriage 1 along the active conveying roller 33 and the driven conveying roller 34, the baffle 317 can limit the rear end of the pallet 2 at the innermost part of the conveying frame 31 to prevent the pallet 2 from colliding with the carriage 1.

[0035] A guard plate 318 is provided on the top of the conveying frame 31, and a receiving space 319 for receiving the conveying sprocket 35 and the transmission chain is provided in the guard plate 318. Since the conveying sprocket 35 and the transmission chain form a transmission system, the guard plate 318 can be provided to protect the conveying sprocket 35 and the transmission chain provided in the receiving space 319 to prevent dust or debris from falling onto the conveying sprocket 35 and the transmission chain, thereby avoiding affecting the transmission effect.

[0036] Specifically, the adjusting device 5 includes an adjusting plate 51 fixedly connected to the limiting plate 4 and a fixing plate 52 fixedly connected to the conveying device 3, so that the fixing plate 52 is fixedly connected to the side of the conveying device 3, and the adjusting plate 51 is fixedly connected to the limiting plate 4, and the position of the limiting plate 4 can be adjusted by adjusting the position of the adjusting plate 51.

[0037] An adjusting screw 53 is fixedly provided on the adjusting plate 51, and an adjusting hole 54 is provided on the fixing plate 52. The adjusting screw 53 can adjust its relative position with the fixing plate 52 by laterally adjusting its lateral position in the adjusting hole 54, and drive the adjusting plate 51 to move laterally, thereby adjusting the position of the limiting plate 4.

[0038] The adjusting screw 53 and the adjusting hole 54 are arranged corresponding to each other. Both ends of the adjusting screw 53 are provided with abutting pieces that can abut against the fixed plate 52. The extrusion force generated by the abutting pieces can be applied to the fixed plate 52. The abutting pieces at both ends of the adjusting screw 53 are tightly fitted with the outer wall of the fixed plate 52, so that the abutting pieces and the fixed plate 52 can cooperate to fix the position of the adjusting screw 53.

[0039] Specifically, the abutment is threadedly connected to the adjusting screw 53 , so that rotating the abutment can cause the abutment to rotate and translate relative to the adjusting screw 53 .

[0040] Specifically, the end of the abutting member facing the fixed plate 52 is provided with a universal pressing head 56 , and the other end of the abutting member is provided with a holding handle 57 . By rotating the holding handle 57 , the universal pressing head 56 can be synchronously driven to rotate, so that the universal pressing head 56 can synchronously press the fixed plate 52 .

[0041] In the embodiment, the abutting handle 57 is an M10 five-star handle, which can be easily rotated and adjusted by the abutting handle 57. Since the universal pressure head 56 needs to abut against the fixed plate 52, the universal pressure head 56 can be set to a disc-shaped structure design to ensure the contact area with the fixed plate 52.

[0042] The universal pressure head 56 is made of polyurethane, so that the universal pressure head 56 will deform under external force and increase its contact area with the fixed plate 52. By increasing the contact area, the stability of the position adjustment of the supporting member can be guaranteed, thereby providing better support for the limiting plate 4.

[0043] The fixing device 6 includes a fixing support 61 fixedly connected to the top of the conveying device 3, and a fixing cylinder 62 is provided on the fixing support 61; a fixing block 64 is provided at the output end of the fixing cylinder 62, and the fixing block 64 can clamp the side of the pallet 2 to fix the position of the pallet 2 on the conveying device 3.

[0044] In addition, guide rods 63 are provided on both sides of the fixed block 64 to guide the moving direction of the fixed block 64. The guide rods 63 are arranged on both sides of the fixed block 64. When the fixed block 64 moves, the guide rods 63 on both sides can guide the fixed block 64 to prevent the movement from causing displacement deviation in the moving direction of the fixed block 64.

[0045] The fixed support 61 is provided with an infrared switch, and the infrared switch is arranged corresponding to the tray 2. When the tray 2 on the conveying device 3 moves to the infrared switch, the infrared switch can control the fixed cylinder 62 to work, so that the fixed cylinder 62 controls the fixed block 64 to extend to clamp and position the two sides of the tray 2. In addition, a rubber pad can be arranged on the side of the fixed block 64 facing the tray 2. The arrangement of the rubber pad can increase the friction of the fixed block 64, and can increase the stability of the clamping of the tray 2.

[0046] During loading, the conveying device 3 translates the pallet 2 stacked with plasma boxes from the entrance and exit 11 to the inside of the carriage 1. During the process of the pallet 2 moving to the inside of the carriage 1, if the infrared switch senses that the pallet has not moved for more than a certain period of time, the infrared switch can control the fixed cylinder 62 to work. In this way, during the loading process, the infrared switches can be triggered in sequence from the inside of the carriage 1 to the entrance and exit 11. The innermost infrared switch of the carriage 1 will first trigger the pallet 2 located inside the carriage 1 to be clamped, and then the infrared switches will be triggered in sequence to clamp the pallet 2. Finally, the infrared switch near the entrance and exit 11 will be triggered to clamp the pallet 2 located at the entrance and exit 11 to complete the final loading.

[0047] When unloading, the conveying device 3 translates the pallet 2 stacked with plasma boxes from the inside of the carriage 1 to the entrance and exit 11. In the process of the pallet 2 moving from the inside of the carriage 1 to the entrance and exit 11, the infrared switch is released in sequence from the entrance and exit 11 to the inside of the carriage 1. The infrared switch at the entrance and exit 11 will be released, and the clamping of the pallet 2 can be released. The pallet 2 at the entrance and exit 11 can be moved out by a forklift, and then the clamping of the pallet 2 by the fixed cylinder 62 is released in sequence. Finally, the infrared switch at the innermost part of the carriage 1 is released, and the pallet 2 at the innermost part of the carriage 1 is moved to the entrance and exit 11. It is then moved out by a forklift to complete the final unloading. The infrared switch can be provided with a control circuit, and only when the outermost fixed cylinder 62 releases the clamping of the pallet, the infrared switch inside can be triggered.

[0048] In other embodiments, the infrared switch may be eliminated and a control button may be installed in the vehicle cab to directly control the corresponding fixed cylinder 62 to perform clamping or releasing operations; in addition, the start, stop and forward and reverse rotation of the conveying device 3 may also be operated by the control button.

[0049] The temperature control device 7 includes an external unit arranged on the outside of the top of the carriage 1 along the length direction of the carriage 1 and an internal unit corresponding to the external unit arranged on the inside of the top of the carriage 1, and the internal unit is arranged corresponding to the accommodating cavity 13, so that the internal temperature of the carriage 1 can be controlled, thereby better meeting the requirements of plasma transportation.

[0050] A fixing opening 41 is provided on the limiting plate 4 at a position corresponding to the output end of the fixing device 6 , and the fixing opening 41 allows the output end of the fixing device 6 to freely pass through, thereby enabling the fixing device 6 to clamp the tray 2 .

[0051] An input plate 42 is provided at a position of the limiting plate 4 corresponding to the inlet and outlet 11 , and the input plate 42 is gradually expanded outward. By arranging the input plate 42 to gradually expand outward, the tray 2 can be conveniently placed at the opening 316 of the conveying device 3 .

[0052] It should be noted that in actual use, the cargo that this transport vehicle can carry is not only limited to plasma boxes, but also includes other cargo that requires refrigerated transportation (such as vaccines, etc.).

[0053] See also Figure 8-9 As shown, the working principle of the present invention is as follows: Before the plasma box automated transport vehicle is put into operation, the temperature control device 7 is first turned on to allow the internal temperature of the carriage 1 to be maintained between 2°C and 8°C.

[0054] When loading, drive the transport vehicle to the 2℃-8℃ receiving area, start the air curtain machine 12 and open the tailgate to make the compartment 1 open, then use a forklift to place the pallet 2 with stacked plasma boxes at the opening 316 of the conveying device 3, and use the conveying device 3 to translate the pallet 2 with stacked plasma boxes from the entrance 11 to the inside of the compartment 1 in sequence. After all the pallets 2 with stacked plasma boxes are transported, start the fixing device 6 to position and clamp both sides of the pallet 2, fix the position of the pallet 2, close the tailgate to seal the compartment 1, and complete the loading.

[0055] When unloading, first drive the transport vehicle to the 2℃-8℃ receiving area, start the air curtain machine 12 and open the tailgate to make the compartment 1 open, cancel the clamping of the fixing device 6 on both sides of the pallet 2, and then use the conveying device 3 to translate the pallet 2 stacked with plasma boxes from the inside of the compartment 1 to the entrance 11 in turn, and then use a forklift to remove the pallet 2 located at the opening 316. After all the pallets 2 stacked with plasma boxes have been moved, close the tailgate to seal the compartment 1 to complete the unloading.

[0056] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
