Description

Technical Field

[0001] This invention belongs to the technical field of intelligent logistics warehousing equipment, specifically relating to a loading and unloading connection device for intelligent logistics warehousing. Background Technology

[0002] Intelligent logistics warehousing is a modern warehousing and logistics system that integrates technologies such as the Internet of Things, big data, artificial intelligence, and automated control. Based on automated warehousing equipment (shelves, stacker cranes, conveyors, etc.), it realizes automated, information-based, and intelligent management and operation of the entire warehousing process (inbound, storage, sorting, outbound, inventory, and connection) through intelligent systems. It is widely used in e-commerce, manufacturing, cold chain logistics and other fields.

[0003] Connecting devices are supporting equipment used in logistics warehousing and industrial transportation scenarios to achieve smooth transfer of goods between two pieces of equipment / work surfaces. Their core function is to eliminate height differences, physical gaps, and angle differences between different loading / unloading / warehousing equipment, allowing goods to be transferred smoothly and without dropping from one work surface (such as warehouse racks or conveyor belts) to another work surface (such as forklifts, truck beds, or sorting equipment). They are key devices for solving equipment connection problems and improving the efficiency and integrity of goods transfer, and are widely used in the loading and unloading process of intelligent logistics warehousing.

[0004] Existing connecting devices generally adopt rigid fixed structures, lacking flexible adaptability. Their fixed height cannot match various types of equipment. In warehousing operations, there are significant differences in the floor height of loading and unloading equipment (box trucks, flatbed trucks, container trucks), the shelf height of storage racks, and the conveyor surface height of conveyors. Fixed heights will cause vertical misalignment. When loading and unloading goods, manual lifting / lowering is required, which can easily cause damage to the platform edges, racks, or truck bodies. Furthermore, gaps may exist at the connection between the connecting device and these types of loading and unloading equipment due to their variable shapes. Subsequent goods (especially cartons, pallets, and irregularly shaped items) may get stuck in these gaps during movement, causing them to tilt, jam, or fall. Soft-packaged goods may also get stuck in the gaps, causing tearing and damage. Summary of the Invention

[0005] This invention provides a loading and unloading connection device for intelligent logistics warehousing, which solves the technical problems in related technologies where fixed heights lead to vertical misalignment, and goods need to be manually lifted / lowered during loading and unloading, making it easy for them to bump into the platform edges, shelves or carriages.

A motor belt drive assembly is fixedly installed at one corner of the connection platform. A pulley is provided at one end of the positioning roller. The motor belt drive assembly drives the positioning roller to rotate through the pulley. When the positioning roller rotates, it synchronously drives the spur gears.

[0008] Preferably, a rectangular frame is fixedly installed on the lower surface of the substrate and the lower surface of the docking platform. The rectangular frame is located at the end away from the support assembly, and the rollers of the roller assembly are located inside the rectangular frame.

[0009] Preferably, a limiting plate is fixedly installed on the upper surface of the mounting connecting plate, and a bearing plate is fixedly connected between the two limiting plates.

[0011] Preferably, a connecting plate is rotatably connected to one end of the movable plate, a second limiting frame is provided on the lower surface of the movable plate near the end of the connecting plate, a first limiting frame is provided on the lower surface of the connecting plate, the first limiting frame and the second limiting frame are aligned, a slider is slidably connected to the inner side of the first limiting frame, and a transmission rod is rotatably connected between the slider and the piston rod of the first linear drive component, the transmission rod being located on both sides of the slider.

[0012] Preferably, a strip groove is provided on the inner side of both the first limiting frame and the inner side of the second limiting frame, and an anti-detachment protrusion is provided at the edge of the upper surface of the slider, with the anti-detachment protrusion located inside the strip groove.

[0013] Preferably, a hollow cylinder is fixedly installed at the bottom of the slider, the hollow cylinder is located between the two transmission rods, a second linear drive component is fixedly installed inside the hollow cylinder, a support plate is fixedly installed at the end of the piston rod of the second linear drive component, a limit block is slidably connected to the upper surface of the support plate, and a guide protrusion is provided at the junction of the support plate and the limit block.

[0014] Preferably, the slider has a cavity inside, the support plate slides in contact with the cavity wall, and a four-bend rod is fixedly connected between the two transmission rods. The four-bend rod is rotatably set inside the cavity and is located between the two limit blocks.

[0015] Preferably, the part where the limiting block contacts the slider is provided with an inclined part, and a spring is fixedly connected between the two limiting blocks, with the spring located above the four-fold bending rod.

[0016] The beneficial effects of this invention are as follows: 1. This invention utilizes a scissor lift assembly in conjunction with a hydraulic cylinder to achieve precise micro-adjustment of the docking platform height. It is compatible with loading and unloading equipment, shelves, and conveyor belts of different heights in warehousing operations, eliminating the need for manual lifting or lowering of goods and preventing collisions and damage between goods and platforms, shelves, and vehicles. Simultaneously, the docking mechanism, through the meshing transmission of a motor belt drive assembly, positioning rollers, spur gears, and toothed plates, can push the movable plate to the working surface of the loading and unloading equipment, filling the connection gap between the docking device and various loading and unloading equipment. This solves the problems of goods easily getting stuck in the gaps, causing tilting, jamming, falling, and damage, significantly improving the integrity of goods loading and unloading, reducing manual intervention and goods loss, and increasing the overall operational efficiency of warehousing and loading / unloading.

[0017] 2. This invention adds a rotatable connecting plate to the end of the movable plate, and is equipped with an angle adjustment structure including a first linear drive component, a slider, and a transmission rod. This not only adapts to different working surfaces such as the forklift fork tilting back, ensuring tightness of the connection, but also effectively separates the toothed plate from the working surface of the loading and unloading equipment, preventing wear on the toothed plate due to friction, extending the service life of the device, and ensuring the smooth extension and retraction of the movable plate. At the same time, the anti-detachment protrusion on the slider cooperates with the strip groove of the limiting frame to prevent the slider from detaching. The positioning plate places the first linear drive component below the movable plate, without occupying cargo transfer space or affecting normal cargo connection operations.

[0030] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0031] Example 1 like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, a loading and unloading connection device for intelligent logistics warehousing includes a base plate 1, a scissor lift assembly 2, and a connection platform 13. The upper surface of the base plate 1 and the lower surface of the connection platform 13 are rotatably connected by the scissor lift assembly 2. A connection mechanism 5 is provided on the top of the connection platform 13. A hydraulic cylinder 4 is rotatably installed on the inner side of the scissor lift assembly 2. The connection mechanism 5 includes a movable plate 52. Mounting connection plates 3 are symmetrically installed at the edge of the upper surface of the connection platform 13. A positioning roller 10 is rotatably installed between the two mounting connection plates 3. The positioning roller 10 is positioned near... Both ends of the mounting connecting plate 3 are provided with spur gears 11. The lower surface of the movable plate 52 is provided with a toothed plate 53. The movable plate 52 is located directly above the spur gears 11. The toothed plate 53 meshes with the spur gears 11. A motor belt drive assembly 9 is fixedly installed at one corner of the docking platform 13. One end of the positioning roller 10 is provided with a pulley 12. The motor belt drive assembly 9 drives the positioning roller 10 through the pulley 12. When the positioning roller 10 rotates, it synchronously drives the spur gears 11, which are used to push the movable plate 52 to move along the direction of the docking platform 13 through the toothed plate 53.

[0032] It should be noted that when using the connecting device, the base plate 1 needs to be installed on the mobile device, which includes, but is not limited to, a transport vehicle or a rail-mounted unmanned vehicle. Then, the mobile device is used to move the connecting device near the loading and unloading equipment. First, according to the height of the loading and unloading equipment, the hydraulic cylinder 4 is activated. The hydraulic cylinder 4 pushes the scissor lift assembly 2 to adjust the height of the connecting platform 13, achieving height adjustment to adapt to loading and unloading equipment and storage racks of different heights. If there is a gap between the connecting platform 13 and the connection point between the storage conveyor belt and the forklift operating surface, the motor belt drive assembly 9 is activated. The drive belt of the motor belt drive assembly 9 is connected to the pulley 12, which drives multiple positioning rollers 10 to rotate synchronously. When the 10 rotates, it pushes the toothed plate 53 through the spur gear 11, pushing one end of the movable plate 52 onto the loading and unloading equipment. This fills the gap at the connection between the connecting device and the loading and unloading equipment, eliminating the gap and preventing the goods from getting stuck in it during subsequent movement. There are three positioning rollers 10, two of which are located at both ends of the connecting platform 13, and the other is located in the middle section of the connecting platform 13. They can stably support the movable plate 52. When pushing the movable plate 52, the three positioning rollers 10 rotate simultaneously until the movable plate 52 is about to detach from the positioning roller 10 in the middle section of the connecting platform 13. The installation connecting plate 3 can determine the direction and route of movement of the movable plate 52, preventing the movable plate 52 from tilting or deviating.

[0033] Furthermore, such as Figure 2 , Figure 3 and Figure 5 As shown, a support assembly 14 is fixedly installed on the lower surface of the docking platform 13 and the upper surface of the base plate 1. The support assembly 14 is rotatably connected to the scissor lift assembly 2. A roller assembly 7 is rotatably installed at the end of the scissor lift assembly 2. The base of the hydraulic cylinder 4 is rotatably connected to the roller assembly 7. The piston rod of the hydraulic cylinder 4 is rotatably connected to the rotating rod of the support assembly 14. A rectangular frame 8 is fixedly installed on the lower surface of the base plate 1 and the lower surface of the docking platform 13. The rectangular frame 8 is located at the end away from the support assembly 14. The rollers of the roller assembly 7 are located inside the rectangular frame 8.

[0034] It should be noted that the scissor lift assembly 2 consists of two or more sets of X-shaped cross links. Multiple sets of X-shaped cross links are hinged with pins to form a telescopic parallelogram frame. The support assembly 14 consists of two bearing seats and a rotating rod. The bearing seats are fixed. The two support assemblies 14 respectively determine the positions of the X-shaped cross links at the upper and lower ends of the scissor lift assembly 2 to ensure the structural stability of the scissor lift assembly 2. When adjusting the height of the docking platform 13, the hydraulic cylinder 4 pushes the X-shaped cross links to rotate around the rotating rod of the support assembly 14. During the rotation, the roller assembly 7 moves along the path of the rectangular frame 8, causing the X-shaped cross links to move. This action allows the scissor lift assembly 2 to have two states: extended and retracted. When the piston rod of the hydraulic cylinder 4 extends, the scissor lift assembly 2 is in the extended state, and the docking platform 13 gradually rises. When the piston rod of the hydraulic cylinder 4 retracts, the scissor lift assembly 2 is in the retracted state, and the docking platform 13 descends smoothly, thereby achieving the purpose of adjusting the height of the docking platform 13.

[0035] Furthermore, such as Figure 3 , Figure 4 and Figure 6 As shown, a limiting plate 6 is fixedly installed on the upper surface of the mounting connecting plate 3, and a bearing plate 15 is fixedly connected between the two limiting plates 6. The bearing plate 15 is located directly above the movable plate 52, and the lower surface of the bearing plate 15 slides in contact with the upper surface of the movable plate 52.

[0036] It should be noted that the limiting plate 6 and the bearing plate 15 form a bearing platform for placing goods, which is located directly above the connecting platform 13. During the process of the movable plate 52 extending from below the bearing plate 15, the bearing plate 15 and the limiting plate 6 can play a pressing role to prevent the movable plate 52 from tilting or lifting.

[0037] Example 2 like Figure 7 , Figure 8 and Figure 9 As shown, when the movable plate 52 extends onto the working surface of the loading and unloading equipment, the toothed plate 53 on the lower surface of the movable plate 52 easily comes into contact with the working surface. As the subsequent goods are continuously pressed down, the toothed plate 53 will rub against the working surface, causing it to wear down. This will affect the subsequent extension and retraction of the movable plate 52. In addition, during loading and unloading, the main loading and unloading equipment in the forklift usually adjusts the forks to a slightly backward angle to prevent the goods from slipping. In order to protect the toothed plate 53 and adapt to the angle of the forklift forks, this application further provides the following technical solution.

[0038] A positioning plate 54 is provided on the lower surface of the movable plate 52. A first linear drive component 55 is fixedly installed on the bottom of the positioning plate 54. The first linear drive component 55 is located above the connecting platform 13. A guide plate 16 is provided on the upper surface of the connecting platform 13. The first linear drive component 55 is slidably connected to the guide plate 16. The first linear drive component 55 is arranged along the length direction of the movable plate 52. A connecting plate 51 is rotatably connected to one end of the movable plate 52. A second limiting frame 59 is provided on the lower surface of the movable plate 52 near the end of the connecting plate 51. A first limiting frame 58 is provided on the lower surface of the connecting plate 51. The first limiting frame 58 is aligned with the second limiting frame 59. A slider 57 is slidably connected to the inner side of the first limiting frame 58. A transmission rod 56 is rotatably connected between the slider 57 and the piston rod of the first linear drive component 55. The transmission rod 56 is located on both sides of the slider 57. A strip groove 510 is provided on the inner side of the first limiting frame 58 and the inner side of the second limiting frame 59. An anti-detachment protrusion 511 is provided at the edge of the upper surface of the slider 57. The anti-detachment protrusion 511 is located inside the strip groove 510.

[0039] It should be noted that when filling the gap between the connecting device and the loading / unloading equipment working surface, the movable plate 52 extends onto the working surface. During this process, the guide plate 16 determines the movement path of the first linear drive component 55, which is an electric push rod. First, the hydraulic cylinder 4 lifts the connecting platform 13 to a position slightly above the working surface. Then, the first linear drive component 55 is activated to push the slider 57 into the interior of the second limit frame 59, allowing the slider 57 to disengage from the movable plate 52. During this process, the transmission rod 56 remains locked. After the slider 57 is fully inside the second limit frame 59, the transmission rod 56 is unlocked, and the first linear drive component 55 pulls the slider 57 back. Since the transmission rod 56 can rotate at this time, its angle changes during the back-pulling process. This changes the angle of the transmission rod 56, which in turn drives the connecting plate 51 via the slider 57, causing the connecting plate 51 to rotate downwards until its end contacts the working surface. At this point, even if the working surface has different angles of backward tilt, the connecting plate 51 can be rotated to contact the working surface. To prevent gaps, if the working surface is horizontal, the connecting plate 51 can be adjusted at a small angle to separate the toothed plate 53 from the working surface without affecting the connection of goods. When the connecting plate 51 is not needed, the transmission rod 56 can be kept locked and brought into the second limiting frame 59 by the first linear drive component 55. At this time, the slider 57 is at the junction of the movable plate 52 and the connecting plate 51, which can reinforce the movable plate 52 and the connecting plate 51. The length of the combination of the movable plate 52 and the connecting plate 51 is longer than the original single movable plate 52. When extended, it can also prevent the toothed plate 53 from contacting the working surface. The anti-detachment protrusion 511 on the slider 57 is adapted to the strip groove 510 to prevent the slider 57 from detaching from the first limiting frame 58 and the second limiting frame 59. The positioning plate 54 determines the position of the first linear drive component 55 and sets it below the movable plate 52, so as not to occupy the space above the movable plate 52, thereby avoiding affecting the transfer of goods.

[0040] Example 3 like Figure 10 and Figure 11 As shown, when the first linear drive component 55 pushes the slider 57 through the transmission rod 56, it will cause the connecting plate 51 to rotate around the movable plate 52. At this time, the transmission rod 56 needs to be in a rotatable state. When the first linear drive component 55 pushes the slider 57 into the first limit frame 58 or the second limit frame 59, the transmission rod 56 needs to remain in a non-rotatable state. In order to lock and unlock the transmission rod 56 at any time according to different needs, this application further provides the following technical solutions.

[0041] A hollow cylinder 512 is fixedly installed at the bottom of the slider 57. The hollow cylinder 512 is located between two transmission rods 56. A second linear drive component 515 is fixedly installed inside the hollow cylinder 512. A support plate 517 is fixedly installed at the piston rod end of the second linear drive component 515. A limit block 516 is slidably connected to the upper surface of the support plate 517. A guide protrusion 518 is provided at the junction of the support plate 517 and the limit block 516. A cavity 514 is opened inside the slider 57. The support plate 517 slides in contact with the cavity wall of the cavity 514. A four-fold bent rod 513 is fixedly connected between the two transmission rods 56. The four-fold bent rod 513 is rotatably disposed inside the cavity 514 and is located between the two limit blocks 516. An inclined part 519 is provided at the contact part between the limit block 516 and the slider 57. A spring 520 is fixedly connected between the two limit blocks 516 and is located above the four-fold bent rod 513.

[0042] It should be noted that the hollow cylinder 512 is used to house the second linear drive component 515, the first linear drive component 55 is an electric push rod, and the four-bend rod 513 connects the two transmission rods 56 to keep them rotating synchronously. When it is necessary to lock the transmission rod 56, the movable plate 52 and the connecting plate 51 are flush, and the second linear drive component 515 pushes the support plate 517 to its highest point. At this time, the limiting block 516 set on the support plate 517 will clamp the four-bend rod 513, restricting the four-bend rod 513 to a certain position. Figure 10 At the angle shown, the four-fold bending rod 513 cannot rotate, which also restricts the rotation of the transmission rod 56. When it is necessary to unlock the transmission rod 56, the second linear drive component 515 drives the support plate 517 to move downward. At this time, the limiting block 516 moves downward simultaneously. During this process, under the rebound of the spring 520, the limiting block 516 will be pushed to move along the guide protrusion 518 towards both ends of the support plate 517, so that the two limiting blocks 516 are separated from the four-fold bending rod 513, releasing the restriction on the four-fold bending rod 513, so as to ensure that the connecting plate 51 can rotate freely within a certain angle. The cavity 514 provides the limit block 516 with a space for movement.

[0043] Furthermore, when it is necessary to rotate the connecting plate 51 back to a state level with the movable plate 52, since the first linear drive component 55 cannot determine the horizontal state of the connecting plate 51, the second linear drive component 515 is activated to push the support plate 517 upward. At the same time, the first linear drive component 55 pushes the transmission rod 56, and the inclined part 519 on the limiting block 516 cooperates with the slider 57, causing the limiting block 516 to move towards the center of the support plate 517. The limiting block 516 will then clamp the four-fold bending rod 513 and rotate it back to its original position. Figure 10At the angle shown, the transmission rod 56 rotates synchronously, pushing the connecting plate 51 back to a horizontal state, thereby ensuring that the connecting plate 51 can rotate back to an angle completely level with the movable plate 52.

[0044] Working principle of the invention: The base plate 1 and the connecting platform 13 are rotatably connected by a scissor lift assembly 2. The scissor lift assembly 2 is formed by two or more sets of X-shaped cross links hinged by pin shafts to form a telescopic parallelogram frame. The support assembly 14 is used to fix the position of the upper and lower ends of the scissor lift assembly 2 to ensure its structural stability. The base of the hydraulic cylinder 4 is rotatably connected to the roller assembly 7 at the end of the scissor lift assembly 2, and the piston rod is rotatably connected to the rotating rod of the support assembly 14. In use, the hydraulic cylinder 4 is activated according to the height of the loading and unloading equipment. The hydraulic cylinder 4 pushes the X-shaped cross links to rotate around the rotating rod of the support assembly 14. The roller assembly 7 moves along the rectangular frame 8 to deform the X-shaped cross links. When the piston rod extends, the scissor lift assembly 2 unfolds and the connecting platform 13 rises. When the piston rod retracts, the scissor lift assembly 2 retracts and the connecting platform 13 descends smoothly, thereby realizing the fine adjustment of the height of the connecting platform 13 to adapt to loading and unloading equipment and storage racks of different heights.

[0045] Next, the motor belt drive assembly 9 drives multiple positioning rollers 10 to rotate synchronously via pulley 12. When the positioning rollers 10 rotate, they drive the toothed plate 53 to move via spur gear 11, thereby pushing the movable plate 52 to move along the direction of the connecting platform 13. This pushes one end of the movable plate 52 onto the loading and unloading equipment, filling the gap at the connection between the connecting device and the loading and unloading equipment, and preventing the goods from getting stuck in the gap when moving. At the same time, the limiting plate 6 and the bearing plate 15 form a cargo carrying platform. The bearing plate 15 is located directly above the movable plate 52 and slides in contact with the upper surface of the movable plate 52. During the extension of the movable plate 52, it plays a pressing role, preventing the movable plate 52 from tilting or warping.

[0046] When filling the gap, first raise the connecting platform 13 to a position slightly higher than the working surface of the loading and unloading equipment. The second linear drive component 515 pushes the support plate 517 to the highest point. The limit block 516 clamps the four-fold bending rod 513 to restrict its rotation, thereby locking the transmission rod 56. Then, the first linear drive component 55 is activated to push the slider 57 into the second limit frame 59. After that, the second linear drive component 515 drives the support plate 517 to move down. The spring 520 rebounds and pushes the limit block 516 to move along the guide protrusion 518 to both ends of the support plate 517, releasing the restriction on the four-fold bending rod 513 to ensure that the connecting plate 51 can rotate freely. Then, the first linear drive component 55 pulls the slider 57 back, the angle of the transmission rod 56 changes, and the slider 57 drives the connecting plate 51 to rotate downward until the end of the connecting plate 51 is in contact with the working surface, adapting to the backward tilt angle of the working surface, and separating the toothed plate 53 from the working surface to avoid wear.

[0047] When the connecting plate 51 is not needed, the second linear drive component 515 pushes the support plate 517 upward, while the first linear drive component 55 pushes the transmission rod 56. The inclined part 519 on the limiting block 516 cooperates with the slider 57 to make the limiting block 516 move towards the center, clamp the four-fold bending rod 513 and drive it to rotate back to the specified angle. Simultaneously, the transmission rod 56 drives the connecting plate 51 back to the horizontal state, ensuring that the two are completely aligned. Then, the first linear drive component 55 pulls back the transmission rod 56, bringing the slider 57 into the second limiting frame 59. At this time, the slider 57 is located at the junction of the movable plate 52 and the connecting plate 51, which plays a reinforcing role. The combination of the connecting plate 51 and the movable plate 52 is longer than the length of a single movable plate 52. When the movable plate 52 extends, the connecting plate 51 overlaps the loading and unloading equipment to avoid the toothed plate 53 from contacting the working surface. The positioning plate 54 fixes the first linear drive component 55 below the movable plate 52 without occupying cargo transfer space.

[0048] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
