Description

Technical Field

[0001] The present application relates to the technical field of loading and unloading equipment, and in particular to a multifunctional automatic loading and unloading vehicle equipment. Background Art

[0002] Loading and unloading operations are key links in logistics and transportation, involving unloading or loading goods from transport vehicles. Traditional loading and unloading methods mainly rely on manual operations, which are inefficient, labor-intensive, and prone to cargo damage and personnel safety accidents. Loading and unloading equipment is an indispensable component in modern logistics, warehousing and manufacturing industries. It is mainly used for loading and unloading operations of goods, aiming to improve loading and unloading efficiency, reduce labor costs, and ensure safety and reliability during operations.

[0003] For example, a loading and unloading device with publication number CN116513837A relates to the technical field of conveying equipment. The prior art includes a transverse moving assembly, a palletizing and depalletizing assembly and a conveying assembly. The transverse moving assembly extends along a first direction, and the transverse moving assembly can extend into and out of the carriage along a second direction, the second direction being orthogonal to the first direction. The palletizing and depalletizing assembly is arranged on the transverse moving assembly and can move relative to the transverse moving assembly along the first direction under the drive of the transverse moving assembly. The conveying direction of the conveying assembly is the second direction, and the conveying assembly is connected to the transverse moving assembly; the palletizing and depalletizing assembly can move in the extending direction of the transverse moving assembly, so as to adjust the position of the palletizing and depalletizing assembly relative to the carriage through the transverse moving assembly, and the conveying assembly is located in the carriage after the articles are conveyed to the palletizing and depalletizing assembly for palletizing. At the same time, the articles in the carriage can be depalletized and conveyed out through the palletizing and depalletizing assembly in the carriage, without the need for transfer equipment, thus saving space and time during the loading and unloading process.

[0004] However, the above-mentioned prior art still has some defects when loading and unloading vehicle cargo: In the above-mentioned prior art, when loading, the transverse movement component is first extended into the car body, and the items are conveyed to the depalletizing and stacking component for stacking through the conveying component. As the space in the car body is gradually filled with items, the transverse movement component gradually moves backwards. In the actual application of vehicle cargo loading and unloading, this piece-by-piece processing method is not only time-consuming, but also requires frequent movement and adjustment of the equipment, resulting in low overall loading efficiency. Especially when handling a large amount of cargo, the stacking process will take up a lot of time, affecting the progress of the entire loading operation.

[0005] At the same time, after the goods produced in the factory are packaged, they are generally stacked on freight pallets, and the goods on the freight pallets are wrapped and fixed with stretch film. When loading, the freight pallets and the goods on them only need to be placed into the car compartment by forklift. However, the above-mentioned existing loading and unloading equipment design does not have the function of processing freight pallets. The transverse movement component and the depalletizing and stacking component cannot identify, clamp or transport complete freight pallets, and can only process individual goods one by one. This makes it impossible to fully utilize the advantages of pre-stacking, but instead increases loading time and labor costs.

[0006] Based on this, and in accordance with the above-mentioned viewpoints, there is still room for improvement in the existing technology for loading and unloading vehicle cargo. Summary of the invention

[0007] In order to solve the above technical problems, the present application provides a multifunctional automatic loading and unloading device, which adopts the following technical solutions: A multifunctional automatic loading and unloading device, comprising a cargo tray and a bottom plate, wherein the lower end of the cargo tray is symmetrically provided with grooves, and the bottom plate is provided with a plurality of symmetrically arranged sliding blocks, each group of sliding blocks corresponds to the grooves, and each group of sliding blocks is provided with a lifter, which is used to lift the cargo tray through the grooves; The lifter comprises a lifting strut rod arranged on a sliding block, a sliding groove is provided on the lifting strut rod, a lifting rod is slidably provided in the sliding groove, and receiving grooves are symmetrically provided on both sides of the lifting rod, and a lifting plate is slidably provided in the receiving groove.

[0036] The following is combined with Figures 1 to 16 This application is described in further detail.

[0037] The embodiment of the present application discloses a multifunctional automatic loading and unloading equipment. The self-propelled cargo pallet can place the cargo according to the size of the car body. When the vehicle arrives at the loading and unloading position, the cargo on the cargo pallet can be pre-loaded into the car body at one time, or the cargo in the car body can be taken out at one time. This not only solves the problem of long waiting time for trucks in traditional loading and unloading methods, but also improves the efficiency of cargo loading and unloading.

[0038] Embodiment 1: Reference Figure 1 and Figure 2 As shown, after the goods produced in the factory are packaged, they are generally stacked on a pallet 1, and the goods on the pallet 1 are wrapped and fixed with a stretch film, and then placed in a loading and unloading area such as a warehouse. Grooves 11 are symmetrically provided at the lower end of the pallet 1, and the grooves 11 are generally used for forklifts and other equipment to fork and load and unload the goods.

[0039] A multifunctional automatic loading and unloading device comprises a bottom plate 2 on which a plurality of groups of symmetrically arranged sliding blocks 21 are arranged, and each group of sliding blocks 21 corresponds to a groove 11.

[0040] When loading the goods, first the walker 4 arranged at the lower end of the bottom plate 2 will drive the bottom plate 2 to move, so that the bottom plate 2 moves to the front of the pallet 1 on which the goods are placed, and each set of sliding blocks 21 is provided with a lifter 3; the lifter 3 will extend out and insert into the groove 11 of the pallet 1, and then lift a row of pallets 1, and then move the pallet 1 with the goods to the bottom plate 2.

[0041] Then the walker 4 starts and moves the bottom plate 2 to the compartment of the truck. The walker 4 will lift the bottom plate 2 to make the bottom plate 2 consistent with the height of the compartment. Then each group of lifters 3 will lift the pallet 1 on the bottom plate 2 again and put it into the compartment at one time, thereby completing the loading of the goods.

[0042] When unloading goods, the walker 4 drives the bottom plate 2 to move to the compartment of the truck. The walker 4 will lift the bottom plate 2 to make the bottom plate 2 consistent with the height of the compartment. The lifter 3 will extend and insert into the groove 11 of the pallet 1. Then each group of lifters 3 will lift a row of goods and move the pallet 1 with goods from the compartment to the bottom plate 2 at one time. After that, the walker 4 will drive the bottom plate 2 to move to the warehouse for placement, thereby completing the unloading of the goods.

[0043] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, specifically, the lifter 3 includes a lifting strut 31 arranged on the sliding block 21, a sliding groove 32 is provided on the lifting strut 31, a lifting rod 33 is slidably provided in the sliding groove 32, accommodating grooves 34 are symmetrically provided on both sides of the lifting rod 33, a lifting plate 35 is slidably provided in the accommodating groove 34, a plurality of interference grooves 36 are provided on the lifting plate 35, a interference block 37 located in the interference groove 36 is slidably provided in the accommodating groove 34, and a connecting rod 38 is commonly provided on the plurality of interference blocks 37.

[0044] When the cargo pallet 1 is lifted up through the groove 11, the transmission shaft 39 rotatably arranged at the bottom of the sliding groove 32 is first driven to rotate through the existing driving technology. The rotating transmission shaft 39 will drive the lifting rod 33 to move outward through the threaded connection with the lifting rod 33, and the lifting rod 33 moving outward will be inserted into the groove 11.

[0045] Afterwards, the transmission screw 381 set in the accommodating groove 34 is driven to rotate. The rotating transmission screw 381 will drive the connecting rod 38 to move through the threaded connection with the connecting rod 38. The moving connecting rod 38 will drive the resistance block 37 to move together. The tightening slope 371 set on the resistance block 37 will correspond to the resistance slope 361 set on one side of the resistance groove 36, and push the lifting plate 35 to move upward to lift the pallet 1 and keep the pallet 1 away from the ground.

[0046] Then the transmission shaft 39 is reversed, and the transmission shaft 39 drives the lifting rod 33 to move inward through the threaded connection. At this time, the lifting plate 35 will drive the lifted pallet 1 to move together, so that the pallet 1 moves to the bottom plate 2; thereby moving the pallet 1 from the warehouse to the carriage or moving the goods from the carriage to the warehouse.

[0047] Among them, a slot 362 is set at the lower end of the resistance groove 36, and a protrusion 372 corresponding to the slot 362 is set at the upper end of the resistance block 37; when the connecting rod 38 drives the resistance block 37 to move the resistance block 37, the protrusion 372 at the upper end of the resistance block 37 will move together until the protrusion 372 is inserted into the slot 362 and the lifting plate 35 is fully raised, thereby lifting the pallet 1 to keep the pallet 1 away from the ground.

[0048] Reference Fig. 9 , Fig.10 and Fig.11 As shown, specifically, the walker 4 includes a top plate 41, and cross rods 42 are symmetrically and rotatably arranged between the top plate 41 and the bottom plate 2, and a lifting shaft 43 is arranged between the cross rods 42 on the same side, and the lifting shaft 43 is threadedly connected to the cross rod 42.

[0049] By driving the lifting shaft 43 to rotate, the rotating lifting shaft 43 will drive one end of the cross rod 42 to move through the threaded connection, so that the base plate 2 is lifted to the same height as that in the car, that is, the rotation of the lifting shaft 43 drives the movement of the cross rod 42 through the threaded connection, and the other end of the cross rod 42 is fixed on the base plate 2, so the base plate 2 will rise smoothly along the trajectory of the cross rod 42. When the base plate 2 rises to the same height as that in the car, the lifting shaft 43 stops rotating. Conversely, the rotation of the lifting shaft 43 drives the movement of the cross rod 42 through the threaded connection, and the other end of the cross rod 42 is fixed on the base plate 2, so the base plate 2 will fall smoothly along the trajectory of the cross rod 42.

[0050] Among them, a plurality of through holes 44 are opened on the bottom plate 2, support plates 45 are symmetrically arranged on both sides of the through holes 44, sliding holes 46 are symmetrically arranged on the support plates 45, sliding blocks 47 are slidably arranged in the sliding holes 46, and sliding connecting rods 491 connected to the sliding blocks 47 are slidably arranged on the support plates 45.

[0051] A running wheel 48 is rotatably arranged between the two sliding blocks 47 . The running wheel 48 is responsible for bearing the weight of the bottom plate 2 and rolling on the ground to realize the movement of the bottom plate 2 .

[0052] By driving the rotating shaft 49 rotatably arranged on the base plate 2 to rotate, the rotating transmission shaft 39 will drive the sliding link 491 to move through the threaded connection with the sliding link 491, and the moving sliding link 491 will drive the sliding block 21 connected thereto to move, and the movement of the sliding block 21 will cause the walking wheel 48 to move downward or upward.

[0053] When the cargo pallet 1 is lifted up through the groove 11, the rotating shaft 49 will rotate to drive the sliding link 491 to move upward, so that the walking wheel 48 moves upward, allowing the bottom plate 2 to contact the top plate 41 to stabilize the bottom plate 2. Similarly, when reaching the unloading position, the rotating shaft 49 drives the walking wheel 48 to move upward, allowing the bottom plate 2 to contact the ground to stabilize the bottom plate 2.

[0054] On the contrary, when the cargo pallet 1 is moved to the unloading location, the rotating shaft 49 will rotate to drive the sliding link 491 to move upward, so that the walking wheel 48 moves upward, allowing the bottom plate 2 to contact the bottom plate 2 to stabilize the bottom plate 2. Similarly, when reaching the unloading position, the rotating shaft 49 drives the walking wheel 48 to move upward, allowing the bottom plate 2 to contact the ground to stabilize the bottom plate 2 and provide sufficient support force and stability to ensure the safety of the equipment when carrying goods.

[0055] Most of the prior art technologies load goods by waiting for the truck to arrive at the loading area and then loading the goods by means of a forklift or other equipment, during which the truck needs to wait. When loading the goods, a pallet 1 containing the goods is first placed on a bottom plate 2 according to the size of the vehicle compartment.

[0056] After the loading vehicle arrives, the bottom plate 2 is aligned with the compartment and raised to the corresponding height, and then the cargo pallet 1 is lifted up by the lifting plate 35, and the lifting rod 33 delivers the cargo pallet 1 loaded with goods into the compartment at one time, thereby completing the loading of the goods at one time to improve the loading efficiency.

[0057] On the contrary, when the cargo in the carriage is unloaded, the lifting plate 35 is raised into the carriage to lift up the cargo pallet 1, and the cargo pallet 1 loaded with the cargo is moved to the bottom plate 2 at one time through the lifting rod 33, thereby completing the cargo unloading at one time.

[0058] Embodiment 2: Reference Fig.12 and Fig.13 As shown, on the basis of the first embodiment, the sliding block 21 is slidably connected to the bottom plate 2 , an adjustment shaft 5 is rotatably provided on the bottom plate 2 through a bracket, and the adjustment shaft 5 slides through a plurality of sliding blocks 21 .

[0059] By rotating the adjusting knob 51 on the sliding block 21, the adjusting knob 51 will move the sliding block 21 on the base plate 2 through the threaded connection with the adjusting shaft 5 to change the position of each group of lifters 3, thereby adapting to the spacing of the grooves 11 on the large and small pallets 1. This not only improves the flexibility and adaptability of the loading and unloading equipment, but also enhances the ease of operation and precision control capabilities of the equipment.

[0060] Embodiment three: Reference Fig.14 , Fig.15 and Fig.16 As shown, on the basis of the first and second embodiments, a lifting member 6 is provided on the lifting rod 33 ; the lifting member is used to move a single pallet 1 .

[0061] Specifically, the lifting member 6 includes a lifting slot 61 provided on the lifting rod 33 , a lifting support plate 62 is slidably provided in the lifting slot 61 , telescopic plates 63 are symmetrically supported on the lifting support plate 62 , and a lifting plate 64 is commonly provided on the two telescopic plates 63 .

[0062] When a single cargo pallet 1 is moved, after the lifting rod 33 is extended, the driving shaft 68 rotatably arranged in the lifting slot 61 is driven to rotate. The rotating driving shaft 68 is threadedly connected with the lifting support plate 62, driving it to move in the lifting slot 61, so that the lifting support plate 62 drives the lifting plate 64 to move to the bottom of the groove 11 of the cargo pallet 1.

[0063] The trigger plate 65 slidingly arranged on the lifting support plate 62 is then pushed to move by the cylinder, and the moving trigger plate 65 will drive several inclined holes 66 opened thereon to move together. Since the lower end of the lifting plate 64 is provided with a trigger shaft 67 located in the inclined hole 66 through a bracket, the movement of the inclined hole 66 will force the trigger shaft 67 to move upward, and drive the lifting support plate 62 to move upward through the bracket, thereby lifting the cargo pallet 1.

[0064] Then the drive shaft 68 reverses, and the rotating drive shaft 68 drives the lifting support plate 62 to drive the lifting plate 64 through the telescopic plate 63, so that the single pallet 1 moves on the lifting rod 33 to place the goods into the car or warehouse, which not only improves the flexibility and adaptability of the loading and unloading equipment, but also enhances the safety and ease of operation of the equipment.

[0065] The implementation principle of the present invention is: (1): When loading goods, the bottom plate 2 is first driven to move by the running wheels 48 so that the bottom plate 2 moves in front of the pallet 1 on which the goods are placed. The lifting rod 33 is inserted into the groove 11, and then the lifting plate 35 is pushed upward to lift the pallet 1 and keep the pallet 1 away from the ground.

[0066] (2): The transmission shaft 39 then reverses and drives the lifting rod 33 to move inward through the threaded connection with the lifting rod 33. At this time, the lifting plate 35 will drive the lifted pallet 1 to move together, so that the pallet 1 moves to the bottom plate 2.

[0067] (3): Then the walker 4 starts and moves the bottom plate 2 to the compartment of the truck. The walker 4 will lift the bottom plate 2 so that the bottom plate 2 is at the same height as the compartment. The transmission shaft 39 drives the lifting rod 33 to move outward through the threaded connection with the lifting rod 33. At this time, the lifting plate 35 will drive the lifted pallet 1 to move together, so that the pallet 1 is moved into the compartment, thereby completing the loading of the goods.

[0068] (4): When unloading the goods, the walker 4 drives the bottom plate 2 to move to the compartment of the truck, lifts the bottom plate 2, and makes the bottom plate 2 consistent with the height of the compartment. When the lifting rod 33 moves outward, the lifting rod 33 will be inserted into the groove 11, and then push the lifting plate 35 to move upward to lift the pallet 1, so that the pallet 1 is away from the bottom of the compartment.

[0069] (5): Then the transmission shaft 39 is reversed, and the transmission shaft 39 drives the lifting rod 33 to move inward through the threaded connection with the lifting rod 33. At this time, the lifting plate 35 will drive the lifted pallet 1 to move together, so that the pallet 1 moves to the bottom plate 2.

[0070] (6): Then the walker 4 is started and the bottom plate 2 is lowered. At this time, the lifting plate 35 drives the lifted pallet 1 to move together, so that the pallet 1 is moved into the warehouse for placement, thereby completing the unloading of the goods.

[0071] (7): When loading goods, first place the cargo pallet 1 loaded with goods on the bottom plate 2 according to the size of the carriage. After the loading vehicle arrives, align the bottom plate 2 with the carriage and raise it to the corresponding height. Then, lift the cargo pallet 1 with the lifting plate 35. The lifting rod 33 sends the cargo pallet 1 loaded with goods into the carriage at one time, thereby completing the loading of goods at one time to improve loading efficiency.

[0072] (8): On the contrary, when unloading the cargo in the compartment, the lifting plate 35 is raised into the compartment to lift up the cargo pallet 1, and the cargo pallet 1 loaded with the cargo is moved to the bottom plate 2 at one time through the lifting rod 33, thereby completing the cargo unloading at one time.

[0073] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
