[0045] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0046] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0047] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0048] The embodiment of the utility model provides a double-station stacker, such as Figure 1 As shown, it includes a top rail 20, a bottom rail 30, a rack 100 and a rack driving device 40. The top rail 20 and the bottom rail 30 are respectively arranged at the top and bottom of the rack 100, and the top rail 20 and the bottom rail 30 are parallel to each other. The rack 100 is slidably connected with the top rail 20 and the bottom rail 30 respectively. The rack driving device 40 is connected to the rack 100 and is used to drive the rack 100 to slide along the top rail 20 and the bottom rail 30, so that the rack 100 can change its position along the extension direction of the top rail 20, and then can dock with different cargo positions on the same shelf, or dock with different shelves. When the rack 100 carries goods, the rack driving device 40 can drive the rack 100 to move to the vicinity of the cargo position opposite to the goods, which can reduce the intermediate circulation time of the goods and improve the efficiency of the goods circulation. Two cargo platforms 200 and two cargo platform driving devices 50 are arranged on the frame 100. The two cargo platform driving devices 50 are respectively connected to the two cargo platforms 200 and are respectively used to drive the two cargo platforms 200 to move in the vertical direction. The goods 10 can be placed directly on the cargo platforms 200 or the pallets loaded with the goods 10 can be placed on the cargo platforms 200. The two cargo platforms 200 can lift the goods 10 at the same time to increase the handling capacity of the goods 10, which can improve the working efficiency of the stacker.

[0049] In some embodiments, a rotatable wheel body is provided at the bottom of the rack 100, and the wheel body is slidably matched with the bottom track 30. When the wheel body rotates, the rack 100 can move along the bottom track 30. The rack driving device 40 is connected to the wheel body and is used to drive the wheel body to rotate, thereby driving the rack 100 to move along the bottom track 30. The rack driving device 40 can specifically include a driver such as a motor and a transmission mechanism connected to the driver.

[0050] In some embodiments, Figure 2As shown, a plurality of groups of rotatable guide wheels can be set at the top of the rack 100 along the extension direction of the top rail 20, and each group of guide wheels includes two guide wheels 101. The two guide wheels 101 are set on both sides of the top rail 20 and are slidably matched with the top rail 20, so that the top of the rack 100 can also move smoothly along the extension direction of the top rail 20.

[0051] Hereinafter, the specific structure of the cargo platform driving device will be described.

[0052] like Figure 3-6 As shown, the cargo platform driving device includes a counterweight 400, a chain 510, a steel wire rope 520 and a lifting drive assembly 300. The cargo platform 200 and the counterweight 400 are both slidably connected to the frame 100 in the vertical direction. When the stacker is working, the cargo platform 200 and the counterweight 400 move in opposite directions. The counterweight 400 can pull the cargo platform 200, thereby allowing the lifting drive assembly 300 to lift the cargo platform 200 with a smaller driving force, thereby reducing the driving force requirement for the lifting drive assembly 300. Both ends of the chain 510 and the steel wire rope 520 are respectively connected to the cargo platform 200 and the counterweight 400. Specifically, both ends of the chain 510 are respectively connected to the cargo platform 200 and the counterweight 400, and both ends of the steel wire rope 520 are also respectively connected to the cargo platform 200 and the counterweight 400. The chain 510 and the steel wire rope 520 can jointly pull the cargo platform 200. The lifting drive assembly 300 is used to drive the chain 510 and the steel wire rope 520 to move synchronously, and the driving force is synchronously transmitted through the chain 510 and the steel wire rope 520, thereby driving the cargo platform 200 to move in the vertical direction, so as to realize the rise and fall of the cargo platform 200.

[0053] In this embodiment, if the chain 510 breaks, the lifting drive assembly 300 can still drive the cargo platform 200 to rise and fall through the steel wire rope 520, thereby preventing the cargo platform 200 from falling, which improves the safety of the stacker. At the same time, the chain 510 and the steel wire rope 520 can share the gravity, reducing the force on the chain 510, so that the chain 510 is not easy to break, thereby extending the service life of the entire stacker.

[0054] In some embodiments, the lifting drive assembly 300 includes a drive shaft 320 rotatably connected to the frame 100, a lifting drive mechanism 310 connected to the drive shaft 320 and used to drive the drive shaft 320 to rotate, a main gear 330 sleeved on the drive shaft 320, and a main drive wheel 340 sleeved on the drive shaft 320, the chain 510 is meshed with the main gear 330, and the wire rope 520 is wound around the main drive wheel 340. When the lifting drive mechanism 310 drives the drive shaft 320 to rotate, it drives the main gear 330 and the main drive wheel 340 to rotate accordingly, the main gear 330 then drives the chain 510 to move, and the main drive wheel 340 then drives the wire rope 520 to move, thereby pulling the cargo platform 200.

[0055] In this embodiment, the chain 510 and the wire rope 520 transmit the driving force from the same drive shaft 320, which can reduce the driving components and simplify the driving structure. The chain 510 and the wire rope 520 can move more synchronously, so that they can be subjected to force at the same time to pull the cargo platform 200 at the same time.

[0056] Further, the lifting drive assembly 300 also includes a driven shaft 350 rotatably connected to the frame 100, a slave gear 360 sleeved on the driven shaft 350, and a slave drive wheel 370 sleeved on the driven shaft 350. The chain 510 is also meshed with the slave gear 360, and the wire rope 520 is also wound on the slave drive wheel 370. The slave gear 360 provides support for the chain 510, which can extend the lateral length of the chain 510 and change the direction of the chain 510 so that the two ends of the chain 510 are respectively connected to the cargo platform 200 and the counterweight 400. Similarly, the slave drive wheel 370 provides support for the wire rope 520, which can extend the lateral length of the wire rope 520 and change the direction of the wire rope 520 so that the two ends of the wire rope 520 are respectively connected to the cargo platform 200 and the counterweight 400.

[0057] In some embodiments, the lifting drive mechanism 310 may include a motor 311 and a reducer 312 connected to the motor 311 .

[0058] In some embodiments, a wire rope limiting mechanism 600 is provided on the outer side of the main driving wheel 340 for limiting the wire rope 520 from detaching from the main driving wheel 340, so that the wire rope 520 can remain wound on the main driving wheel 340, thereby preventing the wire rope 520 from being dislocated.

[0059] Furthermore, a wire rope limiting mechanism 600 for limiting the wire rope 520 from being separated from the driving wheel 370 may also be provided from the outside of the driving wheel 370 , which has a better limiting effect on the wire rope 520 and ensures the driving force of the wire rope 520 .

[0060] Furthermore, the circumference of the main driving wheel 340 is provided with an annular groove, the steel wire rope 520 is wound in the annular groove, and the inner wall of the annular groove can limit the axial movement of the steel wire rope 520 relative to the main driving wheel 340 along the main driving wheel 340. The steel wire rope limiting mechanism 600 includes a limiting bracket 610 fixed on the frame 100 and a limiting top plate 620 connected to the limiting bracket 610. The limiting top plate 620 is located above the main driving wheel 340 and close to the annular groove, so that the steel wire rope 520 is not easy to move out of the annular groove, and the steel wire rope 520 is limited from being separated from the main driving wheel 340.

[0061] In some embodiments, two steel wire ropes 520 are provided, one end of each of the two steel wire ropes 520 is connected to the counterweight 400, and the other ends of each of the two steel wire ropes 520 are respectively connected to the two sides of the cargo platform 200; two groups of chains 510 are provided, one end of each of the two groups of chains 510 is connected to the counterweight 400, and the other ends of each of the two groups of chains 510 are respectively connected to the two sides of the cargo platform 200. In this way, the chains 510 and the steel wire ropes 520 both pull the cargo platform 200 from both sides of the cargo platform 200, so that the cargo platform 200 is evenly stressed, so that the cargo platform 200 can be pulled smoothly to prevent the cargo platform 200 from tilting.

[0062] In some embodiments, a connecting bracket 410 is provided on the top of the counterweight block 400, and the chain 510 and the steel wire rope 520 are fixedly connected to the connecting bracket 410 instead of being directly connected to the counterweight block 400. The connecting bracket 410 provides more installation space to facilitate the fixing of the chain 510 and the steel wire rope 520.

[0063] Furthermore, the connecting bracket 410 includes two connecting vertical plates 411 and a connecting horizontal plate 412 disposed between and connected to the two connecting vertical plates 411. The connecting vertical plates 411 can extend in the vertical direction, and the connecting horizontal plate 412 can extend in the horizontal direction. The chain 510 is fixedly connected to the connecting horizontal plate 412, and the steel wire rope 520 is fixedly connected to the connecting vertical plates 411.

[0064] In the above embodiment, the chain 510 and the wire rope 520 are respectively wound on the corresponding gears and the driving wheel. Due to the weight of the cargo and the counterweight 400, the chain 510 and the wire rope 520 will generate a lateral thrust on the driving shaft 320 and the driven shaft 350. Although the driving shaft 320 and the driven shaft 350 are fastened to the frame through the bearing seat, after long-term use, the bearing seat still has the risk of loosening. In this regard, the utility model provides the following embodiments to solve this problem.

[0065] In some embodiments, Figure 5 and Figure 7As shown, a bearing seat 380 and a bearing seat stopper 390 are fixed on the frame 100, a bearing 351 is sleeved on the end of the driven shaft 350, the bearing 351 is connected to the bearing seat 380, and the driven shaft 350 is rotated through the bearing 351. The bearing seat stopper 390 is fixed on the frame 100 and abuts against the bearing seat 380. When the bearing seat 380 is subjected to a lateral force applied by the chain 510 and the wire rope 520, the bearing seat stopper 390 provides a thrust opposite to the lateral force to the bearing seat 380, thereby reducing the displacement of the bearing seat 380 under the action of the lateral force, which makes it difficult for the bearing seat 380 to loosen, thereby being fastened to the frame 100.

[0066] Further, the bearing seat 380 may include a hoop 381 and two hoop bottom plates 382 connected to the hoop 381, the hoop 381 is sleeved on the outside of the bearing 351, and the two hoop bottom plates 382 are fastened to the frame 100. Specifically, the hoop bottom plates 382 can be fastened to the frame 100 by bolts 383.

[0067] Furthermore, the bearing seat limiter 390 includes a limit support plate 391 and a limit rod 392 . The limit support plate 391 is fixed on the frame 100 . The limit rod 392 is connected to the limit support plate 391 . The limit rod 392 extends in a horizontal direction and abuts against the bearing seat 380 .

[0068] Furthermore, an adjusting member 393 is provided on the limit rod 392, and the limit rod 392 is slidably connected to the limit support plate 391 in the horizontal direction. The adjusting member 393 is used to adjust the position of the limit rod 392 in the horizontal direction, and then the thrust applied by the limit rod 392 to the bearing seat 380 can be adjusted. The closer the limit rod 392 is to the bearing seat 380, the greater the thrust it applies to the bearing seat 380.

[0069] The limiting support plate 391 is provided with a through hole penetrating the plate in the horizontal direction, and the limiting rod 392 is provided in the through hole and can move along the through hole, so that the limiting rod 392 is slidably connected with the limiting support plate 391 in the horizontal direction. The surface of the limiting rod 392 is provided with a thread, and the adjusting member 393 is a nut sleeved on the limiting rod 392, and the outer diameter of the nut is larger than the outer diameter of the through hole, so that it abuts against the side of the limiting support plate 391, and the position of the limiting rod 392 can be adjusted by rotating the nut.

[0070] In order to maintain the smoothness of the counterweight, the counterweight is slidably matched with the corresponding track through the pulley. After long-term use, the pulley and other parts will inevitably be damaged. If the pulley needs to be replaced, due to the pulley structure of the prior art, the entire track needs to be disassembled, which is very troublesome. For this reason, a detachable counterweight sliding structure will be provided below.

[0071] like Figure 8-11As shown, the frame 100 is provided with two vertical guide rails 110 extending in the vertical direction, the two vertical guide rails 110 are spaced at a preset distance, the two vertical guide rails 110 are respectively slidably matched with two groups of pulleys 900, and the two groups of pulleys 900 can be moved along the vertical guide rails 110 respectively, so as to realize the vertical movement of the counterweight 400. The two groups of pulleys 900 are respectively mounted on two groups of mounting plates 910 to facilitate the fixation of the pulleys 900 and also provide conditions for subsequent detachable connection. The counterweight 400 includes a connecting portion 420, which can be integrally connected with the counterweight 400 or fixed on the surface of the counterweight 400. According to actual needs, the connecting portion 420 can be block-shaped, tubular or other shapes. The connecting portion 420 is located between the two vertical guide rails 110, and the counterweight 400 can be located on the outside of the vertical guide rail 110 and spaced a certain distance from the vertical guide rail 110 to avoid friction with the vertical guide rail 110. Two ends of the connecting portion 420 are detachably connected to two sets of mounting plates 910 .

[0072] After the connection part 420 and the mounting plate 910 are disassembled, the connection part 420 and the mounting plate 910 are separated, and the disassembled mounting plate 910 can be moved in the vertical direction so that the mounting plate 910 and the connection part 420 are misaligned, and then the pulley 900 is removed from the vertical guide rail 110 to facilitate the replacement of the pulley 900, which does not require the removal of the entire vertical guide rail 110, and the operation is more convenient. In addition, when a new pulley 900 needs to be installed, the pulley 900 is first slidably matched with the vertical guide rail 110, and then the pulley 900 is moved in the vertical direction so that the mounting plate 910 and the connection part 420 are aligned, and then the mounting plate 910 and the connection part 420 are fixed together to complete the installation.

[0073] In some embodiments, a connecting plate 430 is fixed at both ends of the connecting portion 420, and the connecting plates 430 at both ends of the connecting portion 420 are respectively detachably fixed to two sets of mounting plates 910. Due to being fixed closely together, the contact area between the connecting plate 430 and the mounting plate 910 is larger, and the fixation is relatively more stable. Moreover, the connecting plate 430 and the mounting plate 910 are both plate-shaped structures, and a variety of fixing methods can be used to achieve the fixed connection between the two. The fixing methods are more and more flexible to adapt to the structures of the connecting portion 420, the connecting plate 430 and the mounting plate 910, so as to facilitate the overall assembly.

[0074] Further, the pulley 900 is coaxially connected with a support shaft 920, and the support shaft 920 passes through the mounting plate 910 and is rotatably connected to the mounting plate 910. Therefore, when the pulley 900 rotates, the support shaft 920 also rotates relative to the mounting plate 910, and moves on the vertical guide rail 110 by rotating, so that the counterweight 400 moves more smoothly. The pulley 900 can be set on the side of the mounting plate 910 away from the connecting portion 420, and the support shaft 920 passes through the mounting plate 910 from this side and extends to the side of the mounting plate 910 close to the connecting portion 420. The mounting plate 910 naturally needs to be provided with a corresponding opening for the support shaft 920 to pass through.

[0075] The bottom of the connecting plate 430 is provided with a avoiding groove 431 extending in the vertical direction, and the support shaft 920 extends into the avoiding groove 431 and can move along the avoiding groove 431. The existence of the avoiding groove 431 can avoid the supporting shaft 920, and ensure that the mounting plate 910 and the connecting portion 420 are tightly fixed together. At the same time, after the mounting plate 910 and the connecting plate 430 are disassembled, the mounting plate 910 can be moved downward along the avoiding groove 431, and the support shaft 920 can be removed from the avoiding groove 431 so as not to affect the disassembly of the mounting plate 910.

[0076] Furthermore, the connecting portion 420 has a hollow accommodating cavity, and the avoidance groove 431 penetrates the connecting plate 430 along the thickness direction of the connecting plate 430. The support shaft 920 passes through the avoidance groove 431 and extends into the accommodating cavity, which provides more avoidance space and allows the support shaft 920 to be designed to be longer. The bottom of the connecting portion 420 is provided with a through groove 421 that is connected to the accommodating cavity. When the support shaft 920 moves downward in the vertical direction, it can pass through the through groove 421 so as not to affect the disassembly of the mounting plate 910.

[0077] In some embodiments, a limiting plate 930 adapted to the avoidance groove 431 is fixed to the side of the mounting plate 910 close to the connecting plate 430, and the limiting plate 930 is inserted into the avoidance groove 431 and can move along the avoidance groove 431. The cooperation between the limiting plate 930 and the avoidance groove 431 can limit the movement of the mounting plate 910 to the left and right sides of the avoidance groove 431, and plays a good positioning role for the mounting plate 910, so that it is not easy to shake.

[0078] In some embodiments, a protruding convex ring 940 is provided on the side of the mounting plate 910 close to the connecting plate 430, and the support shaft 920 passes through the convex ring 940. The convex ring 940 is located in the avoidance groove 431 and can move along the avoidance groove 431. The groove wall at the top of the avoidance groove 431 abuts against the convex ring 940, which makes the connecting plate 430 equivalent to hanging on the convex ring 940. The convex ring 940 also bears part of the pressure applied by the connecting plate 430, thereby reducing the stress of the inherent detachable connection structure of the mounting plate 910 and the connecting plate 430.

[0079] In some embodiments, the connecting plate 430 and the mounting plate 910 are fixed together by screws, so as to realize the detachable connection between the connecting plate 430 and the mounting plate 910 by screws. Of course, other detachable connection structures can also be adopted according to actual needs.

[0080] In some embodiments, the mounting plate 910 is provided with a through hole, and a bearing is sleeved on the support shaft 920, and the bearing is clamped in the through hole to realize the rotational connection between the support shaft 920 and the mounting plate 910. At the same time, the bearing is smoother, making the rotation of the support shaft 920 smoother.

[0081] In some embodiments, the inner sides of the two vertical guide rails 110 close to each other are provided with guide rail grooves 120, which extend in the vertical direction. The two sets of pulleys 900 are respectively slidably engaged with the guide rail grooves 120 of the two vertical guide rails 110. The guide rail grooves 120 can limit the movement of the pulleys 900 to both sides, so that the pulleys 900 maintain sliding engagement with the guide rail grooves 120 in the vertical direction.

[0082] The stacker of the utility model can be used to transport liquid materials. The liquid materials can be loaded in containers such as barrels, and the containers loaded with liquid materials are then placed on the loading platform. Due to the inherent characteristics of liquid materials, liquid materials will inevitably spill during the transportation process, and the existing loading platform does not have a structural design to collect these liquids, resulting in the liquids that fall on the loading platform spilling everywhere, which will pollute the storage environment. For this reason, the following will provide a loading platform that can prevent liquids from spilling.

[0083] like Figure 12-14 As shown, the top surface of the cargo platform 200 is provided with a collecting trough 800 and two supporting blocks 230, the collecting trough 800 is located between the two supporting blocks 230, and the pallet 700 to be transported is used to be placed on the top surface of the two supporting blocks 230, so as to support the pallet 700 through the supporting blocks 230. The top surface of the supporting blocks 230 is also provided with a flow blocking structure 260, when the pallet 700 is placed on the supporting blocks 230, the flow blocking structure 260 is located on the outside of the pallet 700 and is used to block the liquid flowing down from the pallet 700 from flowing in the direction of the two supporting blocks 230 away from each other.

[0084] If liquid material is spilled, it will flow onto the tray 700. Part of the liquid on the tray 700 can flow directly to the collecting tank 800, and the other part will flow to the top surface of the bracket block 230. The flow blocking structure 260 can prevent the liquid from flowing to the outside of the bracket block 230, and the liquid will flow to the collecting tank 800 between the two bracket blocks 230. The collecting tank 800 collects the flowing liquid, preventing the liquid from spilling randomly from the cargo platform 200, thereby preventing the storage environment from being polluted, and keeping the storage environment clean.

[0085] In this embodiment, since liquid materials are transported, the liquid materials need to be loaded in containers such as barrels, and the cargo 10 in the figure is a container loaded with liquid materials.

[0086] In some embodiments, the flow blocking structure 260 includes a flow blocking strip protruding from the top surface of the support block 230, and the flow blocking strip has the effect of blocking the liquid from flowing on the top surface of the support block 230, thereby blocking the liquid flowing down from the tray 700 from flowing in the direction away from the two support blocks 230. At the same time, the flow blocking strip has the advantages of simple molding and easy installation.

[0087] Furthermore, the baffle strip is curved, and both ends of the baffle strip extend to the side edges 231 where the two support blocks 230 are close to each other, which is equivalent to the baffle structure formed by the baffle strip only forming an opening at the side edges 231 where the two support blocks 230 are close to each other. The liquid on the top surface of the support block 230 can only flow to the side edges 231 where the support blocks 230 are close to each other, and then directly drip into the collection groove 800 between the two support blocks 230, which has a better blocking effect on the liquid, making it less likely for the liquid on the top surface of the support block 230 to spill at will.

[0088] Furthermore, the baffle strip is curved in an arc shape, which is compatible with the contour shape of the end of the tray 700 and can provide a better blocking effect on the liquid on the top surface of the support block 230 .

[0089] In some embodiments, the inner sides of the two support blocks 230 close to each other are both provided with protruding protrusions 232, and the two sides of the collection tank 800 extend to the bottom of the two protrusions 232. Considering that liquids have the characteristic of flowing down along the wall, due to the provision of the protruding protrusions 232, the liquid on the top surface of the support block 230 will flow along the inner side of the protrusion 232 close to the other support block 230, and the two sides of the collection tank 800 extend to the bottom of the protrusion 232, and the liquid flowing down along the inner side of the protrusion 232 will directly fall into the collection tank 800, avoiding falling outside the collection tank 800, so that the collection tank 800 can collect more spilled liquid, further improving the cleanliness of the storage environment.

[0090] The protrusion 232 of this embodiment may be integrally connected to the support block 230 , or may be fixed to the side of the protrusion 232 .

[0091] Furthermore, guide plates 810 inclined outward are provided on both sides of the collection tank 800, and the height of the guide plates 810 gradually increases in the direction of outward extension. When a portion of the liquid drips onto the guide plates 810, the guide plates 810 can guide the liquid, so that the liquid flows along the inclined surface of the guide plates 810 into the collection tank 800. At the same time, when the liquid drips onto the horizontal plane structure, the liquid will splash around, and when the liquid drips onto the guide plates 810, due to the inclined surface structure of the guide plates 810, the liquid mainly splashes toward the collection tank 800, thereby reducing the liquid splashing out of the collection tank 800, so that the collection tank 800 can collect more spilled liquid, further improving the cleanliness of the storage environment.

[0092] In some embodiments, the bottom wall of the collecting tank 800 is inclined, and a drainage hole 820 is provided at the lowest point of the bottom wall of the collecting tank 800. Liquid dripping into the collecting tank 800 will flow to the lowest point of the bottom wall of the collecting tank 800 under the action of gravity. When a certain amount of liquid is loaded in the collecting tank 800, the collected liquid can be discharged through the drainage hole 820 to prevent the liquid in the collecting tank 800 from overflowing. The drainage hole 820 can be connected to a corresponding collecting device through a pipeline, so that the liquid is collected in the collecting device.

[0093] In some embodiments, Fig.15 As shown, the top surface of the tray 700 is provided with a plurality of guide grooves 701, which extend to the end of the tray 700. The liquid spilled onto the tray 700 will flow along the guide grooves 701 and then flow out from the end of the tray 700, so that it is easy to drip onto the top surface of the support block 230.

[0094] Some automated warehouses have high requirements for cargo positioning, requiring pallets to be placed at designated locations on the loading platform, but existing loading platforms cannot position pallets, resulting in deviations in the placement of pallets. To this end, a loading platform that can position pallets will be provided below.

[0095] like Figure 16-17As shown, the goods 10 are used to be placed on the pallet 700, and the pallet 700 is used to be placed on the top surface of the cargo platform 200, so as to drive the goods 10 to move as the cargo platform 200 is raised or lowered. The top surface of the cargo platform 200 is provided with a plurality of positioning posts 210 extending upward, and the bottom surface of the pallet 700 is provided with a plurality of positioning holes 710 adapted to the positioning posts 210. Specifically, the positions, number and size of the positioning holes 710 can correspond to the positions, number and size of the positioning posts 210, respectively, so that each positioning post 210 has a positioning hole 710 adapted thereto. When the pallet 700 is placed on the top surface of the cargo platform 200, the positioning posts 210 are inserted into the positioning holes 710 adapted thereto, and the pallet 700 is positioned by the cooperation between the positioning posts 210 and the positioning holes 710, so that the pallet 700 can be placed at the correct position on the cargo platform 200 every time, which is convenient for the subsequent handling of the pallet 700.

[0096] In some embodiments, the positioning hole 710 includes an introduction portion 711 and a positioning portion 712, the positioning portion 712 is located above the introduction portion 711, and the positioning portion 712 is connected to the introduction portion 711. In the direction of downward extension, the aperture of the introduction portion 711 gradually increases. The larger aperture of the introduction portion 711 makes it easier for the positioning column 210 to be inserted into the introduction portion 711. At the same time, the introduction portion 711 will play a certain guiding role for the positioning column 210. When the positioning column 210 is not aligned with the positioning portion 712, under the action of the gravity of the tray 700, the positioning column 210 will slide on the inner wall of the introduction portion 711, thereby guiding the positioning column 210 to be finally inserted into the positioning portion 712. This structure reduces the difficulty of aligning the positioning column 210 with the positioning hole 710, making it easier for the positioning column 210 to be inserted into the positioning hole 710.

[0097] In some embodiments, the top surface of the cargo platform 200 is also provided with a placement groove, and the bottom of the pallet 700 is provided with a positioning protrusion 720 that is compatible with the placement groove. When the pallet 700 is placed on the top surface of the cargo platform 200, the positioning protrusion 720 is embedded in the placement groove, so as to further position the pallet 700 through the cooperation of the positioning protrusion 720 and the placement groove, thereby further ensuring that the pallet 700 can be placed in the correct position on the cargo platform 200.

[0098] Furthermore, the placement groove penetrates the cargo platform 200 in the front-to-back direction, and the two side walls of the placement groove will move from the left and right limit positioning protrusions 720 to position the pallet 700 in the left and right directions. At the same time, when a four-way truck or a forklift places the pallet 700 on the cargo platform 200, the placement groove can avoid the fork arms of the four-way truck and the forklift, so that the pallet 700 can be smoothly placed on the cargo platform 200.

[0099] Furthermore, the cargo platform 200 includes two brackets 230 located on the top thereof, the two brackets 230 both extend in the front-rear direction, a placement slot is formed between the two brackets 230, and both sides of the pallet 700 are placed on the top surfaces of the two brackets 230, so that the pallet 700 is supported by the two brackets 230. Positioning posts 210 are provided on the top surfaces of the two brackets 230, and the positioning posts 210 on the top surfaces of the two brackets 230 can be used to position the pallet 700.

[0100] In some embodiments, the support block 230 can slide in the front-to-back direction, and a locking member is provided on the support block 230. When the two support blocks 230 slide in the rear direction synchronously, the placement position of the tray 700 in the front-to-back direction can be adjusted. After the position is adjusted, the locking member is used to lock and fix the support block 230 so that the support block 230 cannot slide in the front-to-back direction, and is thus fixed in the adjusted position. When the position of the support block 230 needs to be adjusted, the locking member releases the locking of the support block 230.

[0101] Furthermore, the cargo platform 200 includes two guide rails 240 located at the top thereof, both extending in the front-rear direction, and the two support blocks 230 are respectively slidably matched with the two guide rails 240, so that the support blocks 230 can slide in the front-rear direction. The surface of the support block 230 is provided with a threaded hole penetrating therethrough, and the locking member is a bolt threadedly connected to the threaded hole. By screwing the bolt, the length of the bolt extending into the threaded hole changes. When the bolt abuts against the guide rail 240, a large friction force is generated between the bolt and the guide rail 240, so that the bolt can lock and fix the support block 230 on the guide rail 240. When the bolt is separated from the guide rail 240, the bolt no longer locks and fixes the support block 230.

[0102] In some embodiments, a positioning member 750 is provided at the bottom of the pallet 700, and a sensor 250 for detecting the positioning member 750 is provided at the top of the cargo platform 200. The sensor 250 will detect the positioning member 750 only when the pallet 700 is placed at the correct position on the cargo platform 200. If the position where the pallet 700 is placed on the cargo platform 200 deviates greatly from the correct position, the sensor 250 will not detect the positioning member 750. Thus, the sensor 250 can be used to determine whether the position where the pallet 700 is placed on the cargo platform 200 is correct. The sensor 250 may be a photoelectric sensor, and the positioning member 750 may be a corresponding reflective plate.

[0103] In some embodiments, the top surface of the support block 230 of this embodiment may also be provided with the flow blocking structure of the above embodiment, and accordingly, the collection tank 800 is provided at the bottom of the placement tank. The portion of the support block 230 protruding from the side of the guide rail may form the protrusion of the above embodiment. A bracket extending upward may be fixed in the collection tank, and the sensor 250 is fixed on the top of the bracket to prevent the liquid in the collection tank from affecting the operation of the sensor 250.
