Description

Technical Field

[0001] The present invention relates to the technical field of cargo transportation, and in particular to a multimodal cargo seamless transfer device and an operation method thereof. Background Art

[0002] As an advanced logistics and transportation mode, multimodal transportation is based on the integration of different modes of transportation (such as road, rail, air, water, etc.) to achieve seamless and efficient transportation of goods from the departure point to the destination. This mode of transportation can not only significantly improve logistics efficiency, but also significantly reduce logistics costs. It is an indispensable and important part of the modern logistics system.

[0003] For example, the patent application with the prior art announcement number CN106379747B discloses a multimodal transport intercommunication system, which at least includes: an elevated column, a rail system, a cargo moving vehicle, a switching device, and a processor; the switching device is used to transfer the cargo loading device from the transport vehicle to the cargo moving vehicle and load it onto the cargo moving vehicle, or to unload the cargo loading device from the cargo moving vehicle and transport it to the transport vehicle; the processor is connected to the cargo moving vehicle and the switching device; the ports and railway and aviation logistics centers are connected through the rail system, the switching device is controlled by the processor to transfer the cargo loading device, and after the cargo loading device is connected to the cargo moving vehicle, the cargo moving vehicle is controlled to move on the rail beam, thereby realizing multimodal transport between the port and the railway and aviation logistics center. In addition, replacing the road cargo loading device transport truck with the rail system not only improves the transportation efficiency, but also reduces the pressure on ground transportation and protects the environment.

[0004] Although the current advanced rail system technology has significantly improved the efficiency of seamless cargo transfer between road transport and other modes of transport, and achieved efficient flow of cargo in the land transport section, it has encountered a bottleneck that cannot be ignored in the crucial loading and unloading link at the port terminal. Specifically, since the truck loading platform generally follows strict international or regional height standards, while the stacking of containers on the ship deck is limited by the ship design, load capacity and route conditions, its height is often more flexible and variable. This height difference directly leads to huge challenges in the loading and unloading process. Operators have to frequently adjust the height and angle of the lifting equipment, and sometimes even need to use additional auxiliary tools or manpower to ensure that the container can be accurately transferred from the truck to the ship, or from the ship to the truck. According to industry statistics, due to this height difference and the resulting complex operations, the average loading and unloading time of a single container is extended by about 30% compared with the ideal state, which directly leads to a significant decline in terminal operation efficiency. These negative effects not only push up logistics costs, but also pose a serious threat to the smoothness and reliability of the entire multimodal transport process, hindering the pace of the logistics industry towards a more efficient and greener direction. To this end, the present application proposes a multimodal cargo seamless transfer device and an operation method thereof. Summary of the invention

The clamping cylinder and the fixing block ensure the stable fixation of the container during the transfer process and prevent the container from shaking and falling off. The design of the transfer assembly (including the adjusting cylinder, the turning handle, the light rod, the screw rod and the driving motor) enables the inclination angle of the transfer plate to be flexibly adjusted to adapt to the transfer requirements of different heights and positions. The threaded connection between the screw rod and the connecting seat further enhances the stability of the container during the transfer process, especially at both ends of the transfer plate. The buffer assembly composed of the air cylinder and the piston rod effectively slows down the sliding speed of the container on the transfer plate, preventing rapid sliding or even loss of control due to gravity or excessive inclination of the transfer plate, thereby significantly improving the safety of the transfer process.

[0022] The sliding of multiple blocking blocks in the transfer plate slows down the initial sliding speed of the container, providing time for subsequent buffering. Secondly, when the container is close to completely passing through the blocking block, the buffer plate flips under the drive of the power component to form a screen, further blocking and slowing down the sliding speed of the container. This double buffering mechanism greatly improves the safety of the transfer process and reduces the risk of damage or accidents caused by excessive speed or loss of control of the container. The kinetic energy generated when the container slides down is cleverly converted into the pressure energy of the gas in the cylinder, and then transmitted to the receiving cylinder through a series of pipes and components to drive the piston and screw to move. In this process, the energy conversion and transmission efficiency is high, and the natural power of the container sliding down is fully utilized to achieve energy saving.

[0040] Example 1: Please refer to Figure 1 , Figure 3 as well as Figure 4The present invention provides a technical solution: a multimodal cargo seamless transfer device, comprising a support 100, a container 107 and a transfer plate 101, wherein the two sides of the transfer plate 101 are respectively fixedly connected with a rotating shaft 207, and the top of the support 100 is fixedly connected with a bearing seat 206 for supporting the rotation of the rotating shaft 207, and the cooperation between the bearing seat 206 and the rotating shaft 207 can allow the transfer plate 101 to tilt, and a movable seat 102 is arranged below the transfer plate 101, and a transfer plate 104 for grabbing the container 107 is arranged at the bottom of the movable seat 102, and a slide groove 208 for sliding connection of the movable seat 102 is provided at the bottom of the transfer plate 101, and when the transfer plate 101 is tilted, the weight of the container 107 applied to the movable seat 102 will cause it to slide, thereby One end slides into the lower end, a plurality of blocking blocks 300 are arranged inside the slide groove 208, and a buffer component that increases the damping force of the plurality of blocking blocks 300 is arranged inside the transfer plate 101. By arranging the mutual cooperation of the blocking blocks 300 and the buffer component, the sliding speed of the transfer plate 101 can be effectively slowed down, and the gravity acceleration formed by its rapid sliding can be blocked. A transfer component for driving the transfer plate 101 to tilt is arranged on the top of the support 100, and the transfer component can effectively drive the transfer plate 101 to tilt. A plurality of steel cables 103 fixedly connected to the transfer plate 104 are fixedly connected at the bottom of the movable seat 102, and clamping cylinders 105 are respectively fixedly connected at both ends of the transfer plate 104, and a fixed block 106 for fixing the container 107 is fixedly connected to the output end of the clamping cylinder 105.

[0041] For further information, see Figure 2 , Figure 5 as well as Figure 6In order to facilitate the adjustment of the inclination angle of the transfer plate 101, the transfer assembly includes a top frame 200 fixedly connected to the top of the support 100, the top frame 200 is rotatably connected to an adjusting cylinder 201, the output end of the adjusting cylinder 201 is fixedly connected to a handle 202, the bottom of the handle 202 is rotatably connected to the inside of the transfer plate 101, the bottom of the transfer plate 101 is rotatably connected to a light rod 203, the two ends of the light rod 203 are respectively fixedly connected to a screw rod 204, the top of the movable seat 102 is fixedly connected to a connecting seat 209 threadedly connected to the screw rod 204, the bottom of the transfer plate 101 is fixedly connected to a driving motor 205 fixedly connected to the output end of the screw rod 204, and the top of the movable seat 102 is rotatably connected to the top frame 2 00, and the bottom of the handle 202 is rotatably connected to the inside of the transfer plate 101, so that the adjusting cylinder 201 can effectively drive the handle 202 to move and drive the transfer plate 101 to tilt, and at the same time, the two ends of the light rod 203 are respectively fixedly connected with the screw rod 204, so that the container 107 can be fixed when it is located at the two ends of the transfer plate 101, so as to facilitate the grabbing and unloading of the container 107 and improve the stability. At the same time, the inclination of the transfer plate 101 and the coordination between the screw rod 204 can change the position of the container 107 to the greatest extent, so as to adapt to the transfer work at different positions. The flexible use of the transfer component can facilitate the transfer of high-altitude goods, and also facilitate the transportation of low-altitude goods to high places, which is suitable for multimodal transport of goods.

[0042] For further information, see Figure 7 , Figure 8 as well as Fig. 9 In order to slow down the rapid sliding of the container 107 under the influence of gravity and the inclination angle of the transfer plate 101, the buffer assembly includes a plurality of gas cylinders 301 fixedly connected to the inside of the transfer plate 101, the bottoms of the plurality of gas cylinders 301 are slidably connected with piston rods 302 adapted thereto, the bottoms of the plurality of piston rods 302 are fixedly connected to the plurality of blocking blocks 300, the outer surfaces of the plurality of piston rods 302 are sleeved with reset springs 303 for driving them to reset, and the bottoms of the plurality of blocking blocks 300 are constructed as inclined surfaces, and the initial states of the plurality of blocking blocks 300 are all located inside the slide groove 208, so that when the movable seat 102 moves, the plurality of blocking blocks 300 will be continuously moved upward by the force resistance, thereby transmitting the piston rod 302 to squeeze the gas inside the gas cylinder 301, and suppressing the sliding speed of the movable seat 102 under the influence of the interaction force, thereby slowing down the moving speed of the container 107.

[0043] Among them, see Fig.10 , Fig.12 as well as Fig.13In order to facilitate the adjustment of the gas volume inside the gas cylinder 301 and enhance the strength of the gas inside the gas cylinder 301, the tops of the multiple gas cylinders 301 are connected to the gas supply pipe 304, and a gas collecting pipe 306 is arranged above the transfer plate 101. Both ends of the gas collecting pipe 306 are connected to the gas collecting pipe 305 connected to the multiple gas supply pipes 304. The bottom of the gas collecting pipe 306 is connected to the gas receiving cylinder 307, and the inside of the gas receiving cylinder 307 is slidably connected with a piston 310. The top of the gas receiving cylinder 307 is connected to an air release pipe 308, wherein the piston 310 will first block the gas in the gas collecting pipe 306 from leaking. At this time, a stable force can be provided to the gas cylinder 301, so that the blocking block 300 can effectively suppress the movement speed of the movable seat 102.

[0044] It is worth mentioning that the function of the screw rod 204 is to fix the position of the movable seat 102 at the two ends of the transfer plate 101. The positions of the two ends are the positions for unloading and loading. At this time, fixing the movable seat 102 can provide stability for unloading and loading. At the same time, the rotation of the screw rod 204 can provide a certain acceleration for the sliding of the movable seat 102, so that the movable seat 102 can slide. At the same time, the function of adjusting the cylinder 201 can flexibly adjust the height of the two ends of the transfer plate 101, so it can be flexibly used regardless of high or low loading and unloading.

[0045] Specifically, the support 100 is installed at the desired position, and then the two ends of the transfer plate 101 are respectively located on the two transport tools. The adjusting cylinder 201 can be turned on to push the handle 202 downward to drive the transfer plate 101 to tilt, so that the transfer plate 104 at one end of the transfer plate 101 is lifted to the desired height position, and then the driving motor 205 can be driven to drive the light rod 203 to rotate so that the light rod 203 cooperates with the connecting seat 209 to drive the movable seat 102 to move, thereby adjusting the lateral position of the transfer plate 104, and then the clamping cylinder 105 is turned on to drive the fixing block 106 to move, so that the fixing block 106 contacts the container 107 to fix it, and then the opening can be continued. The driving motor 205 is started to drive the light rod 203 to rotate, thereby driving the screw rod 204 to rotate, so that the movable seat 102 moves, so that the connecting seat 209 slides on the outer surface of the light rod 203. At this time, the transfer plate 104 is affected by gravity and slides in the slide groove 208, and then it will continue to conflict with multiple blocking blocks 300, thereby slowing down the sliding speed of the container 107. Finally, the movable seat 102 will slide to the other end of the required transfer plate 101, and finally the connecting seat 209 will be stuck on the outer surface of the screw rod 204. Then, the driving motor 205 is turned on to drive the screw rod 204 to rotate to change the movement of the movable seat 102, and then the fixed block 106 is driven away from the container 107 to achieve unloading.

[0046] In summary, through the tilting design of the transfer plate 101, combined with the sliding of the movable seat 102 in the slide groove 208, the automatic transfer of the container 107 from a high place to a low place is realized, without a lot of manpower intervention, and the transfer efficiency is improved. The clamping cylinder 105 and the fixing block 106 ensure the stable fixation of the container during the transfer process, and prevent the container from shaking and falling off. The transfer component includes the design of the adjusting cylinder 201, the turning handle 202, the light rod 203, the screw rod 204 and the driving motor 205, so that the tilt angle of the transfer plate 101 can be flexibly adjusted to adapt to the transfer requirements of different heights and positions. The threaded connection between the screw rod 204 and the connecting seat 209 further enhances the stability of the container during the transfer process, especially at the two ends of the transfer plate. The buffer assembly composed of the air cylinder 301 and the piston rod 302 effectively slows down the sliding speed of the container 107 on the transfer plate 101, and prevents rapid sliding or even loss of control due to gravity or excessive tilt angle of the transfer plate, thereby significantly improving the safety of the transfer process.

[0047] Example 2: Please refer to Fig.10 , Fig.11 as well as Fig.15 The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: a multimodal cargo seamless transfer device, a plurality of buffer plates 402 for buffering the container 107 are arranged at the bottom of the transfer plate 101, and the plurality of buffer plates 402 can further resist the container 107 to slow down its falling speed, and at the same time, the buffer plates 402 will not block the normal passage of the container 107, and the buffer plates 402 will only be displayed when the container 107 is about to completely pass through the plurality of blocking blocks 300, and a power assembly for driving the buffer plate 402 to rotate is arranged inside the air receiving cylinder 307, and the power assembly includes a piston 310 slidably connected to the inside of the air receiving cylinder 307, and one end of the piston 310 is fixed A screw rod 309 is connected, and a plurality of rotating rods 403 are rotatably connected to the bottom of the transfer plate 101. The bottoms of the plurality of rotating rods 403 are respectively fixedly connected to vertical plates 400 connected to a plurality of buffer plates 402. One end of the screw rod 309 is connected to a movable plate 406. The tops of the plurality of rotating rods 403 are fixedly connected to cranks 404. The interiors of the plurality of cranks 404 are provided with movable grooves 405 adapted to the movable plates 406. By setting a power component, the buffer plates 402 can be driven to flip to form a screen to block the container 107, thereby slowing down the sliding speed of the container 107. In order to allow the cranks 404 to be flexibly pushed, movable grooves 405 are provided for the movable plates 406 to be driven.

[0048] Further, in order to increase the distance that the screw rod 309 pushes the movable plate 406 to move, please refer to Fig.12 , Fig.13 as well as Fig.14, the internal rotation of one end of the air receiving cylinder 307 is connected with a ball 314 adapted to the screw 309, the outer surface of the screw 309 is sleeved with a spring 311 for resetting the piston 310, and the end of the screw 309 away from the piston 310 is threadedly connected with a threaded sleeve 312, and the end of the threaded sleeve 312 away from the screw 309 is fixedly connected with a tension spring 313 fixedly connected to the movable plate 406. When the screw 309 moves, the thread on its outer surface will cooperate with the ball 314 to drive itself to rotate. At this time, the rotation of the screw 309 will cooperate with the threaded sleeve 312 to move the threaded sleeve 312 away from the screw 309. At this time, the threaded sleeve 312 will be pushed away from the screw 309 by two torques, thereby further pushing the movable plate 406 to move, and under the action of the tension spring 313, the buffer plate 402 can continue to rotate under the action of external force, and the container 107 can resist it and push it to rotate.

[0049] Among them, the interior of the vertical plate 400 is fixedly connected with multiple sliding rods 401, the outer surfaces of the sliding rods 401 are slidably connected with sliding seats 407, one side of the sliding seats 407 is rotatably connected with a hinged plate 409 rotatably connected to the buffer plate 402, and the outer surface of the sliding rod 401 is sleeved with a shock-absorbing spring 408 fixedly connected to the sliding seat 407.

[0050] Specifically, the sliding of the plurality of blocking blocks 300 in the transfer plate 101 drives the piston rod 302 to slide in the gas cylinder 301, so that the gas in the gas cylinder 301 is pushed to the inside of the gas delivery pipe 304 and transported to the gas collecting pipe 305. As the gas in the gas collecting pipe 305 gradually increases, it will be transported to the gas collecting pipe 306. Subsequently, the gas enters the gas receiving cylinder 307 and pushes the piston 310 to move, thereby driving the screw 309 to move, so that the screw 309 pushes the threaded sleeve 312 to move, thereby driving the movable plate 406 to move. At the same time, when the screw 309 moves, the ball 314 will be positioned at the upper limit of the thread on the outer surface of the screw 309, thereby driving the screw 309 to rotate. At this time, the screw 309 will be in contact with the screw The grooved sleeve 312 cooperates to further push the movable plate 406 to move, so that the movable plate 406 translates and slides in the movable groove 405, thereby driving the crank 404 to rotate and driving the rotating rod 403 to rotate, thereby rotating the vertical plate 400, and then the two vertical plates 400 form a closed state, thereby blocking the movement of the container 107, buffering the impact of the container 107 so that the slide seat 407 slides on the slide rod 401 to squeeze the shock-absorbing spring 408, and then turning on the drive motor 205 can drive the screw rod 204 to rotate and drive the movable seat 102 to move and continuously resist the buffer plate 402, so that the tension spring 313 is subjected to tension to open the channel of the vertical plate 400 for the container 107 to pass through.

[0051] In summary, the sliding of multiple blocking blocks 300 in the transfer plate 101 slows down the initial sliding speed of the container 107, providing time for subsequent buffering. Secondly, when the container 107 is close to completely passing through the blocking blocks 300, the buffer plate 402 is flipped under the drive of the power component to form a screen, further blocking and slowing down the sliding speed of the container. This double buffering mechanism greatly improves the safety of the transfer process and reduces the risk of damage or accidents caused by excessive speed or loss of control of the container. The kinetic energy generated when the container 107 slides down is cleverly converted into the pressure energy of the gas in the cylinder 301, and then transmitted to the receiving cylinder 307 through a series of pipes and components, driving the piston 310 and the screw 309 to move. In this process, the energy conversion and transmission efficiency is high, and the natural power of the container sliding down is fully utilized to achieve energy saving.

[0052] Example 3: Please refer to Figures 1 to 15 The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: an operation method of a multimodal cargo seamless transfer device, comprising the following steps:

[0053] S1. When in use, first install the support 100 at the desired position, then make the two ends of the transfer plate 101 respectively placed on the two transport tools, and then drive the transfer plate 101 to tilt by opening the regulating cylinder 201 and pushing the handle 202 downward, so that the transfer plate 104 at one end of the transfer plate 101 is lifted to the desired height position;

[0054] S2, then the driving motor 205 can be driven to drive the light rod 203 to rotate so that the light rod 203 cooperates with the connecting seat 209 to drive the movable seat 102 to move, thereby adjusting the lateral position of the transfer plate 104, and then the clamping cylinder 105 is turned on to drive the fixing block 106 to move, so that the fixing block 106 contacts the container 107 to fix it, and then the driving motor 205 can be turned on again to drive the light rod 203 to rotate, thereby driving the screw rod 204 to rotate, so that the movable seat 102 moves, so that the connecting seat 209 slides on the outer surface of the light rod 203. At this time, the transfer plate 104 slides in the slide groove 208 under the influence of gravity, and then it will continuously contact with a plurality of blocking blocks 300, thereby slowing down the sliding speed of the container 107, and finally the movable seat 102 will slide to the other end of the required transfer plate 101, and finally the connecting seat 209 is stuck on the outer surface of the screw rod 204, and then the driving motor 205 is turned on to drive the screw rod 204 to rotate to change the movement of the movable seat 102;

[0055] S3, at the same time, drive the multiple blocking blocks 300 to slide in the transfer plate 101, thereby driving the piston rod 302 to slide in the gas cylinder 301, so that the gas in the gas cylinder 301 is pushed to the inside of the gas pipe 304 and transported to the gas collection pipe 305. As the gas in the gas collection pipe 305 gradually increases, it will be transported to the gas collecting pipe 306. Then the gas enters the gas receiving cylinder 307 and pushes the piston 310 to move, thereby driving the screw 309 to move, so that the screw 309 pushes the threaded sleeve 312 to move, thereby driving the movable plate 406 to move. At the same time, when the screw 309 moves, it will make the ball 314 is positioned at the upper limit of the thread on the outer surface of the screw rod 309, thereby driving the screw rod 309 to rotate. At this time, the screw rod 309 will cooperate with the threaded sleeve 312 to further push the movable plate 406 to move, so that the movable plate 406 translates and slides in the movable groove 405, thereby driving the crank 404 to rotate and drive the rotating rod 403 to rotate, thereby causing the vertical plate 400 to rotate, and then the two vertical plates 400 form a closed state, thereby blocking the movement of the container 107, buffering the impact of the container 107, and causing the slide seat 407 to slide on the slide rod 401 to squeeze the shock-absorbing spring 408;

[0056] S4. Then, the driving motor 205 is turned on to drive the screw rod 204 to rotate and drive the movable seat 102 to move and continuously resist the buffer plate 402, so that the tension spring 313 is subjected to tension and opens the channel of the vertical plate 400 for the container 107 to pass through. Then, the adjusting cylinder 201 can also be adjusted to adjust the inclination angle of the transfer plate 101, thereby changing the height of the container 107 to achieve transfer.
