Description

Technical Field

[0001] The present invention relates to the technical field of logistics unloading platforms, and in particular to an adjustable logistics unloading platform and an unloading method thereof. Background Art

[0002] The deepening trend of globalization has promoted the development of international trade. With the expansion of the global supply chain network, the demand for transporting goods from the place of manufacture to the place of sale has increased significantly. This demand is not only reflected in consumer goods, but also in industrial raw materials, parts and components. In this context, logistics has become a key element connecting all links of the supply chain, directly affecting the circulation efficiency and cost of goods. The rise of e-commerce has greatly changed the traditional logistics model. E-commerce platforms such as Alibaba and Amazon rely on efficient logistics systems to meet the needs of fast and accurate delivery. The last mile delivery has become a key area of ​​logistics development, and the express delivery industry and same-city delivery services have expanded rapidly. The development of the logistics industry is accompanied by the rapid popularization of information technology, artificial intelligence, big data and the Internet of Things. These technological applications have promoted the intelligent transformation of logistics:

[0003] Modern logistics centers, distribution centers and warehouses have put forward higher requirements for unloading platforms. With the rapid development of e-commerce, express delivery business and new retail, logistics facilities need to handle more diversified goods, especially large and heavy goods. Traditional manual unloading methods have been unable to meet the efficiency and safety requirements, so automated and standardized unloading platforms have come into being. Handling efficiency: With the increase in transportation volume and delivery frequency, unloading efficiency has become an important factor in determining the efficiency of logistics operations. Flexibility: Different types of vehicles and goods require unloading platforms of different specifications and configurations, which requires the platform to have a certain degree of adjustability. Logistics unloading platforms are usually built outside the warehouse building and directly connected to the truck loading and unloading area. In order to ensure the efficiency and safety of the loading and unloading process, the design and structural technology of the unloading platform are constantly optimized, including the following aspects: Height adjustment technology: Due to the different heights of truck compartments, the unloading platform usually adopts a hydraulic lifting system or a mechanical adjustment system to match the height of different vehicles. Horizontal adjustment and buffer design: The gap and unevenness between the unloading platform and the vehicle may cause the goods to fall or be damaged.

[0004] Since the height of the logistics warehouse is fixed, and different truck compartments have different heights, when the logistics platform is adjusted up or down, the transportation device at the other end will be affected and move away from the warehouse, resulting in reduced unloading efficiency.

[0005] In view of the above situation, in order to overcome the above technical problems, the present invention designs an adjustable logistics unloading platform and an unloading method thereof, which solves the above technical problems. Summary of the invention

[0006] The technical purpose to be achieved by the present invention is to design an adjustable logistics unloading platform and an unloading method thereof. When the logistics platform is raised or lowered due to different heights of the cargo boxes, the length of the conveying device is adjusted so that its horizontal length on the ground remains unchanged, so that it can be fixedly installed in the initial section of the conveying device in the logistics warehouse to improve transportation efficiency.

[0007] In order to achieve the above technical objectives, the present invention provides the following technical solutions:

[0008] This adjustable logistics unloading platform is a device designed specifically for modern logistics loading and unloading needs. The structure includes a fixed base, lifting rods, logistics platform, transportation mechanism, connection mechanism and transition components, aiming to improve loading and unloading efficiency, ensure safety and adapt to a variety of logistics scenarios. The following is an introduction to the specific structure and functions of the platform:

[0009] The fixed base is the basic structure of the entire unloading platform. It is installed on the ground of the logistics unloading area and is usually made of reinforced concrete or high-strength alloy materials to ensure the stability and load-bearing capacity of the platform during use. The fixed base can not only withstand the gravity of the goods and equipment, but also withstand the impact force generated by the vehicle during loading and unloading.

[0010] The lifting rod is installed on the upper part of the fixed base and has the function of lifting and lowering. The lifting rod adopts a hydraulic or electric lifting device, which can automatically adjust the height of the logistics platform according to the height of different truck compartments to achieve docking. This adjustment function solves the problem of fixed height of traditional unloading platforms, effectively improves applicability and ease of operation, and is suitable for various types of vehicles (such as vans, refrigerated trucks and flatbed trucks, etc.). The adjustment range design of the lifting rod fully considers the height differences of different transport vehicles to ensure smooth and efficient loading and unloading processes.

[0011] The logistics platform is the main working area for unloading operations and is installed on the top of the lifting rod. The platform is designed as a non-slip structure and the surface is covered with wear-resistant and non-slip materials to ensure the safety of operators even in wet environments. The size and load-bearing capacity of the logistics platform are designed according to the needs of different logistics centers to accommodate the loading and unloading of bulk goods or heavy equipment. The platform has a certain vibration resistance and load-bearing performance, which can effectively resist the impact force during loading and unloading.

[0012] The transport mechanism is installed at an angle on the side of the logistics platform to facilitate the smooth transfer of goods from the carriage to the platform. The transport mechanism is equipped with an adjustment component, which can be automatically controlled by the operation button to adjust its length to adapt to different sizes of truck carriages, which requires the logistics platform to be at different heights. This design improves the flexibility of the logistics platform, enabling it to achieve effective loading and unloading in a limited space, and is suitable for narrow unloading areas or high-frequency loading and unloading environments.

[0013] The connecting mechanism is installed inside the transport mechanism and is mainly used to connect and fix adjacent transport mechanisms. When the transport mechanisms are pulled apart, the structure automatically locks through the self-locking principle of the worm gear, ensuring that the two transport mechanisms are firmly docked when unfolded to prevent cargo from falling or platform instability. The connecting mechanism can be quickly adjusted when unfolding and retracting, which is convenient for operators to use flexibly in different loading and unloading scenarios.

[0014] The transition component is installed above the connection mechanism and is responsible for providing continuous support for the goods when the connection mechanism is opened. The transition component adopts an elastic support structure, which will automatically spring up when the platform is unfolded to form a smooth transition surface, making it easy for the goods to slide from the carriage to the logistics platform and avoid damage to the goods due to height differences. This design not only improves loading and unloading efficiency, but also protects fragile or irregularly shaped goods and reduces the damage rate.

[0015] The transport mechanism includes a transport plate, a transport roller, a telescopic slot, a limit rod, an adjustment component and an operating button, etc., with a compact design and multiple functions. Specifically, the transport plate, as the main part of the transport mechanism, carries the goods and provides a stable surface, with good wear resistance and load-bearing capacity. A transport roller is installed above the transport plate, which reduces the friction between the goods and the platform by rolling, facilitates the sliding of the goods on the platform, and thus improves the loading and unloading efficiency. A telescopic slot is provided on the side of the transport plate for installing and adjusting the connecting mechanism. The limit rod is located above the telescopic slot, which plays a role of fixing and limiting, and helps the movement of the connecting mechanism to remain stable. The adjustment component installed on the side is responsible for adjusting the exposed length and angle of the connecting mechanism to meet the requirements of different carriage heights and sizes. The operating button is installed on the top of the transport plate, which is convenient for the operator to control the adjustment component through the button, further improving the convenience and safety of use.

[0016] The adjustment component includes key components such as a micro motor, a rotating worm, a matching worm wheel and an adjustment gear, and has a compact structure and exquisite design. First, the micro motor is installed inside the transport plate, and the motor is a bidirectional rotating motor that can realize forward and reverse rotation to meet the adjustment needs in different directions. The output end of the micro motor is connected to the rotating worm. When the motor is started, the worm rotates accordingly, producing a precise transmission effect. A matching worm wheel is installed on the side of the rotating worm. The worm and the worm wheel are meshed with each other. The worm wheel rotates under the drive of the worm to complete the force transmission process. An adjustment gear is installed below the worm wheel. Its main function is to rotate coaxially with the worm wheel so as to push the connecting plate through the adjustment tooth hole, further refine and control the adjustment action, and realize the length and angle adjustment of the transport mechanism. Through this design, the adjustment component can accurately control the expansion and contraction and adjustment of the connecting mechanism, ensure the stability of the loading and unloading process and the flexibility of operation, and greatly improve the efficiency and safety of the unloading platform.

[0017] The adjusting gear and the rotating worm adopt a coaxial design structure. This layout realizes the synchronous rotation of the two and ensures the stability and accuracy of the transmission process. Thanks to the self-locking characteristics between the worm wheel and the worm, when the system is subjected to external force, the transition plate cannot push the adjusting gear to rotate in the opposite direction, thereby realizing the self-locking function of the system. This design can effectively prevent the transport plate from loosening or accidentally moving during the adjustment process, improve the safety and reliability of the device, and ensure stable operation during cargo loading and unloading.

[0018] The connecting mechanism includes a connecting plate, a positioning hole, a spring hole and an adjustment tooth hole. The overall structural design is compact, the function is clear, and it can achieve stable connection and flexible adjustment. Specifically, the connecting plate, as the main part of the connecting mechanism, is made of high-strength alloy material and installed inside the transportation mechanism. It has good wear resistance and impact resistance and can withstand repeated operations and cargo impact. A positioning hole is provided in the middle of the connecting plate, and its main function is to accurately locate and fix related components to ensure the structural stability during loading and unloading. There are multiple spring holes evenly distributed around the positioning hole. These holes are used to install spring sleeves. After installation, the spring sleeves can provide elastic support and enhance the stability of the transition assembly. In addition, a series of adjustment tooth holes are provided on the side of the connecting plate, which are used to cooperate with the adjustment gear for locking and adjustment, so as to achieve precise adjustment of the length and angle during docking. This structural design not only improves the reliability of the connecting mechanism, but also enables it to adapt to a variety of different loading and unloading requirements, and its flexibility is significantly enhanced.

[0019] The horizontal cross-sectional shape of the adjustment tooth hole is set to a trapezoid, and the trapezoidal setting can improve the tightness of the clamping and the smoothness of the rotation. The trapezoidal structure can form a self-locking effect, and its design of varying width can provide a larger contact area during clamping, increase friction, thereby enhancing the close fit between the connecting plate and the gear, reducing the risk of loosening, and improving the stability of the system. The trapezoidal cross-sectional design can effectively guide the meshing process of the gears, reduce friction resistance and jamming, and make the rotation of the adjustment component smoother. At the same time, this design can reduce the jamming problem caused by wear of the gears during rotation and extend the service life of the connection mechanism. The design of the trapezoidal tooth hole can more evenly disperse the load pressure, reduce the stress concentration phenomenon at the edge of the tooth hole, reduce the probability of material fatigue and damage, and further enhance the durability and safety of the adjustment component.

[0020] The connecting mechanism further includes a telescopic block, a limit groove and a movable groove, with perfect design details and significantly improved functions. Specifically, the telescopic block is installed on the two side edges of the connecting plate, and is made of high-strength material. It has good compressive resistance and can withstand the tensile and compressive stresses generated during cargo loading and unloading. A limit groove is provided above the telescopic block, and the cross-sectional shape of the limit groove is semicircular. This design can effectively guide the sliding of the limit rod, while reducing friction and ensuring the stability of the telescopic block during movement. The semicircular structure of the limit groove also provides a certain buffering effect to avoid damage to components due to excessive displacement. A movable groove is provided on the inner side of the telescopic block. The movable groove is used to accommodate an adjustment rod or other movable parts, providing sufficient space for flexible adjustment, so that the connecting mechanism can adapt to different loading and unloading scenarios and adjustment requirements, and improve the flexibility and adaptability of the overall structure.

[0021] The transition assembly includes a transition plate, a transition roller shaft, a movable plate, a positioning shaft and a spring sleeve. The structural design is precise and can effectively improve the continuity and stability of cargo loading and unloading. First of all, the transition plate, as the main part of the transition assembly, is installed above the connecting mechanism and plays a role of connection and support. The material is made of wear-resistant alloy with high impact resistance and durability. The transition roller shaft installed on the surface of the transition plate is used to reduce the friction between the cargo and the plate surface, facilitate the smooth sliding of the cargo, and reduce the damage to the cargo caused by friction. The movable plates are located on both sides of the transition plate and can be adjusted according to the size and shape of the cargo to provide additional support and protection to prevent the cargo from slipping or falling.

[0022] In addition, the transition assembly also includes a positioning shaft and a spring sleeve, wherein the positioning shaft is fixedly installed under the transition plate to stabilize the position of the transition assembly. The spring sleeve is wrapped around the positioning shaft, and uses the elastic buffering characteristics of the spring to effectively absorb the impact force generated when the cargo is pressed down, thereby improving the stability and rebound effect of the transition assembly, thereby achieving a smooth transition and ensuring the safety of the cargo and loading and unloading efficiency.

[0023] An adjustable logistics unloading method is used in conjunction with the above-mentioned adjustable logistics unloading platform; the steps of the method are as follows:

[0024] S1: The staff adjusts the lifting rod to rise by means of pneumatic and hydraulic methods, so that the logistics platform rises to the high working point;

[0025] S2: The staff presses the operation button, and the micro motor receives the command and starts to rotate. One end of the micro motor is installed on the rotating worm and rotates forward, driving the matching worm wheel to rotate;

[0026] S3: The adjusting gear and the matching worm gear rotate coaxially, so that the connecting plate connected to the adjusting gear through the adjusting tooth hole begins to be exposed;

[0027] S4: When the connecting plate is completely exposed, the spring in the spring sleeve pops out the transition plate. At this point, the transition assembly is located in the middle of the two transport mechanisms, thereby extending the transport route.

[0028] The beneficial effects of the present invention are as follows:

[0029] 1. The present invention integrates multiple functions such as height adjustment, length adjustment, automatic connection and elastic transition by cleverly setting the transport mechanism and the connecting mechanism, so that the equipment can flexibly adapt to different logistics loading and unloading environments, and solves the problems of inconvenient operation, low efficiency and potential safety hazards common in traditional loading and unloading methods. Specifically, the system promotes the operation of the connecting mechanism through the adjustment component, so that the length of the transport mechanism can be flexibly adjusted, so as to cope with the transportation needs of different heights and sizes. During the loading and unloading process, the system can automatically adjust the height of the transport mechanism to adapt to vehicles and warehouse platforms of different heights. At the same time, through the cooperation of the connecting mechanism, the horizontal length of the transport mechanism remains unchanged when the platform is raised and lowered, avoiding the situation where the position of the transport mechanism is unstable due to height changes in traditional equipment. In this way, during the rise of the logistics platform, the tail end of the transport mechanism can be fixedly connected to the first section of the logistics warehouse transportation system to form a stable transportation channel, ensuring seamless docking between the transport equipment and the warehouse system. The core advantage of this design is that it can realize fully automatic transportation and reduce the need for manual operation. Traditional logistics loading and unloading operations usually rely on manual docking, which is not only inefficient, but also prone to operating errors, resulting in equipment damage or transportation interruption. The present invention realizes the precise connection between the transportation mechanism and the logistics warehouse system through the automated connection and adjustment functions, greatly improves the loading and unloading efficiency and accuracy, reduces manual intervention, and reduces operational risks.

[0030] 2. The present invention has strong adaptability and can meet the needs of different types of transport vehicles and goods. Whether it is carriages of different heights or goods of different specifications, the height and length can be automatically adjusted to ensure stability and safety during transportation. The elastic transition component further improves the stability during loading and unloading, and reduces the impact and damage that may occur during transportation. Through the present invention, the loading and unloading efficiency of the logistics center is significantly improved, while the intensity and cost of manual operation are greatly reduced. This innovative design not only improves operating efficiency, but also effectively improves the safety and adaptability of the transportation system, and is suitable for various complex logistics environments.

[0042] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0043] like Figure 1-8 As shown, this adjustable logistics unloading platform is a device designed specifically for modern logistics loading and unloading needs. The structure includes a fixed base 1, a lifting rod 2, a logistics platform 3, a transportation mechanism 4, a connecting mechanism 5 and a transition component 6, which is designed to improve loading and unloading efficiency, ensure safety and adapt to various logistics scenarios. The following is an introduction to the specific structure and functions of the platform:

[0044] The fixed base 1 is the basic structure of the entire unloading platform, installed on the ground of the logistics unloading area, and is usually made of reinforced concrete or high-strength alloy materials to ensure the stability and load-bearing capacity of the platform during use. The fixed base 1 can not only withstand the gravity of the goods and equipment, but also withstand the impact force generated by the vehicle during loading and unloading.

[0045] The lifting rod 2 is installed on the upper part of the fixed base 1 and has a lifting and adjusting function. The lifting rod 2 adopts a hydraulic or electric lifting device, which can automatically adjust the height of the logistics platform 3 according to the height of different truck compartments to achieve docking. This adjustment function solves the problem of fixed height of traditional unloading platforms, effectively improves applicability and ease of operation, and is suitable for various types of vehicles (such as vans, refrigerated trucks and flatbed trucks, etc.). The adjustment range design of the lifting rod 2 fully considers the height differences of different transport vehicles to ensure smooth and efficient loading and unloading processes.

[0046] The logistics platform 3 is the main working area for unloading operations and is installed on the top of the lifting rod 2. The platform is designed as a non-slip structure, and the surface is covered with wear-resistant and non-slip materials to ensure the safety of operators even in wet environments. The size and load-bearing capacity of the logistics platform 3 are designed according to the needs of different logistics centers to accommodate the loading and unloading of bulk goods or heavy equipment. The platform has a certain vibration resistance and load-bearing performance, which can effectively resist the impact force during loading and unloading.

[0047] The transport mechanism 4 is installed obliquely on the side of the logistics platform 3 to facilitate the smooth transfer of goods from the compartment to the platform. The transport mechanism 4 is provided with an adjustment component 45, which can be automatically controlled by the operation button 46 to adjust its length to adapt to the different sizes of truck compartments that require the logistics platform 3 to be at different heights. This design improves the flexibility of the logistics platform 3, enabling it to achieve effective loading and unloading in a limited space, and is suitable for narrow unloading areas or high-frequency loading and unloading environments.

[0048] The connection mechanism 5 is installed inside the transport mechanism 4, and is mainly used to connect and fix adjacent transport mechanisms 4. When the transport mechanisms 4 are pulled apart, the structure automatically locks through the self-locking principle of the worm gear, ensuring that the two transport mechanisms 4 are firmly docked when unfolded, preventing the goods from falling or the platform from being unstable. The connection mechanism 5 can be quickly adjusted when unfolding and retracting, which is convenient for operators to use flexibly in different loading and unloading scenarios.

[0049] The transition component 6 is installed above the connecting mechanism 5 and is responsible for providing continuous support for the goods when the connecting mechanism 5 is opened. The transition component 6 adopts an elastic support structure, which will automatically pop up when the platform is unfolded to form a smooth transition surface, which facilitates the goods to slide from the carriage into the logistics platform 3 and prevents the goods from being damaged due to the height difference. This design not only improves the loading and unloading efficiency, but also protects fragile or irregularly shaped goods and reduces the damage rate.

[0050] like Figure 3 As shown, the transport mechanism 4 includes a transport plate 41, a transport roller 42, a telescopic slot 43, a limit rod 44, an adjustment component 45 and an operation button 46, etc., with a compact design and multiple functions. Specifically, the transport plate 41, as the main part of the transport mechanism 4, carries the goods and provides a stable surface, and has good wear resistance and load-bearing capacity. A transport roller 42 is installed above the transport plate 41, and its function is to reduce the friction between the goods and the platform by rolling, and facilitate the sliding of the goods on the platform, thereby improving the loading and unloading efficiency. A telescopic slot 43 is provided on the side of the transport plate 41 for installing and adjusting the connecting mechanism 5. The limit rod 44 is located above the telescopic slot 43, and plays a role of fixing and limiting, helping the movement of the connecting mechanism 5 to remain stable. The adjustment component 45 installed on the side is responsible for adjusting the exposed length and angle of the connecting mechanism 5 to meet the requirements of different carriage heights and sizes. The operation button 46 is installed on the top of the transport plate 41, which is convenient for the operator to control the adjustment component 45 through the button, further improving the convenience and safety of use.

[0051] like Figure 4-5 As shown, the adjustment component 45 includes key components such as a micro motor 451, a rotating worm 452, a matching worm wheel 453 and an adjustment gear 454, and has a compact structure and exquisite design. First, the micro motor 451 is installed inside the transport plate 41. The motor is a bidirectional rotating motor that can achieve forward and reverse rotation to meet the adjustment requirements in different directions. The output end of the micro motor 451 is connected to the rotating worm 452. When the motor is started, the worm rotates accordingly to produce a precise transmission effect. The side of the rotating worm 452 is equipped with a matching worm wheel 453. The worm and the worm wheel are meshed with each other. The worm wheel rotates under the drive of the worm to complete the force transmission process. An adjustment gear 454 is installed below the worm wheel. Its main function is to rotate coaxially with the worm wheel so as to push the connecting plate 51 through the adjustment tooth hole 54, further refine and control the adjustment action, and realize the length and angle adjustment of the transport mechanism 4. Through this design, the adjustment component 45 can accurately control the extension and adjustment of the connecting mechanism 5, ensuring the stability of the loading and unloading process and the flexibility of operation, which greatly improves the efficiency and safety of the unloading platform.

[0052] The adjusting gear 454 and the rotating worm 452 are coaxially arranged. This layout realizes the synchronous rotation of the two, ensuring the stability and accuracy of the transmission process. Thanks to the self-locking characteristics between the worm wheel and the worm, when the system is subjected to external force, the transition plate 61 cannot push the adjusting gear 454 to rotate in the opposite direction, thereby realizing the self-locking function of the system. This design can effectively prevent the transport plate 41 from loosening or accidentally moving during the adjustment process, improve the safety and reliability of the device, and ensure stable operation during cargo loading and unloading.

[0053] like Figure 6 As shown, the connection mechanism 5 includes a connection plate 51, a positioning hole 52, a spring hole 53 and an adjustment tooth hole 54. The overall structure is compact and has clear functions, and can achieve stable connection and flexible adjustment. Specifically, the connection plate 51, as the main part of the connection mechanism 5, is made of high-strength alloy material and installed inside the transportation mechanism 4. It has good wear resistance and impact resistance and can withstand repeated operations and cargo impact. A positioning hole 52 is provided in the middle of the connection plate 51, and its main function is to accurately locate and fix related components to ensure the structural stability during loading and unloading. A plurality of spring holes 53 are evenly distributed around the positioning hole 52. These holes are used to install spring sleeves 65. After installation, the spring sleeves 65 can provide elastic support and enhance the stability of the transition assembly 6. In addition, a series of adjustment tooth holes 54 are provided on the side of the connection plate 51, which are used to cooperate with the adjustment gear 454 for locking and adjustment, so as to achieve precise adjustment of length and angle during docking. This structural design not only improves the reliability of the connection mechanism 5, but also enables it to adapt to a variety of different loading and unloading requirements, and its flexibility is significantly enhanced.

[0054] The horizontal cross-sectional shape of the adjustment tooth hole 54 is set to a trapezoid, and the trapezoidal setting can improve the tightness of the clamping and the smoothness of the rotation. The trapezoidal structure can form a self-locking effect, and its design of varying width can provide a larger contact area during clamping, increase friction, thereby enhancing the close fit between the connecting plate 51 and the gear, reducing the risk of loosening, and improving the stability of the system. The trapezoidal cross-sectional design can effectively guide the meshing process of the gears, reduce friction resistance and jamming, and make the rotation of the adjustment component 45 smoother. At the same time, this design can reduce the jamming problem caused by wear of the gears during rotation and extend the service life of the connecting mechanism 5. The design of the trapezoidal tooth hole can more evenly disperse the load pressure, reduce the stress concentration phenomenon at the edge of the tooth hole, reduce the probability of material fatigue and damage, and further enhance the durability and safety of the adjustment component 45.

[0055] The connecting mechanism 5 further includes a telescopic block 55, a limiting groove 56 and a movable groove 57, with perfect design details and significantly improved functions. Specifically, the telescopic block 55 is installed on the two side edges of the connecting plate 51, and is made of high-strength material, has good compressive resistance, and can withstand the tensile and compressive stresses generated during cargo loading and unloading. A limiting groove 56 is provided above the telescopic block 55, and the cross-sectional shape of the limiting groove 56 is semicircular. This design can effectively guide the sliding of the limiting rod 44, while reducing friction, and ensuring the stability of the telescopic block 55 during movement. The semicircular structure of the limiting groove 56 also provides a certain buffering effect to avoid damage to the components due to excessive displacement. The inner side of the telescopic block 55 is provided with a movable groove 57, which is used to accommodate the adjustment rod or other movable parts, and provides sufficient space for flexible adjustment, so that the connecting mechanism 5 can adapt to different loading and unloading scenarios and adjustment requirements, and improve the flexibility and adaptability of the overall structure.

[0056] like Figure 7-8 As shown, the transition assembly 6 includes a transition plate 61, a transition roller shaft 62, a movable plate 63, a positioning shaft 64 and a spring sleeve 65. The structural design is precise and can effectively improve the continuity and stability of cargo loading and unloading. First, the transition plate 61, as the main part of the transition assembly 6, is installed above the connecting mechanism 5, and plays the role of connection and support. The material is made of wear-resistant alloy, which has high impact resistance and durability. The transition roller shaft 62 installed on the surface of the transition plate 61 is used to reduce the friction between the cargo and the plate surface, facilitate the smooth sliding of the cargo, and reduce the damage to the cargo caused by friction. The movable plates 63 are respectively located on both sides of the transition plate 61, and can be adjusted according to the size and shape of the cargo to provide additional support and protection to prevent the cargo from sliding or falling.

[0057] In addition, the transition assembly 6 also includes a positioning shaft 64 and a spring sleeve 65, wherein the positioning shaft 64 is fixedly installed below the transition plate 61 to stabilize the position of the transition assembly 6. The spring sleeve 65 is wrapped around the positioning shaft 64, and utilizes the elastic buffering characteristics of the spring to effectively absorb the impact force generated when the cargo is pressed down, thereby improving the stability and rebound effect of the transition assembly 6, thereby achieving a smooth transition and ensuring the safety of the cargo and the efficiency of loading and unloading.

[0058] An adjustable logistics unloading method is used in conjunction with the above-mentioned adjustable logistics unloading platform; the steps of the method are as follows:

[0059] S1: The staff adjusts the lifting rod 2 to rise by means of pneumatic and hydraulic pressure, so that the logistics platform 3 rises to the high working point;

[0060] S2: The staff presses the operating button 46, and the micro motor 451 receives the command and starts to rotate. One end of the micro motor 451 is mounted on the rotating worm 452 and rotates forward, driving the matching worm wheel 453 to rotate;

[0061] S3: The adjusting gear 454 rotates coaxially with the matching worm gear 453, so that the connecting plate 51 engaged with the adjusting gear 454 through the adjusting tooth hole 54 begins to be exposed;

[0062] S4: When the connecting plate 51 is completely exposed, the spring in the spring sleeve 65 pops out the transition plate 61. At this point, the transition assembly 6 is located between the two transport mechanisms 4, thereby extending the transport route.

[0063] During the working process of the present invention, the staff adjusts the lifting rod 2 to rise by means of pneumatic and hydraulic methods, so that the logistics platform 3 rises to the high working point;

[0064] The staff presses the operating button 46, and the micro motor 451 receives the command and starts to rotate. One end of the micro motor 451 is installed on the rotating worm 452 and rotates forward, driving the matching worm wheel 453 to rotate; the adjusting gear 454 rotates coaxially with the matching worm wheel 453, so that the connecting plate 51 connected to the adjusting gear 454 through the adjusting tooth hole 54 begins to be exposed. When the connecting plate 51 slides from the transport mechanism 4, the limiting rod 44 and the limiting groove 56 maintain its movement stability;

[0065] When the connecting plate 51 is fully exposed, the spring in the spring sleeve 65 pops out the transition plate 61, and the movable plate 63 is intercepted by the movable groove 57 so that the transition plate 61 remains stable. The goods pass from the transport plate 41 through the transition plate 61 and then through the transport plate 41 next to it. At this point, the transition assembly 6 is located in the middle of the two transport mechanisms 4, realizing the extension of the transport route. During this period, the bottom of the goods contacts the transport roller and the transition roller shaft 62, and the goods are quickly transported to the logistics warehouse by rolling.

[0066] Various modifications to the present disclosure will be apparent to those of ordinary skill in the art, and the general principles defined herein may be applied to other variations without departing from the scope of the present disclosure. Therefore, the present disclosure is not limited to the examples and designs described herein, but should be given the widest scope consistent with the principles and novel features disclosed herein. Although one or more exemplary embodiments of the present disclosure have been described with reference to the accompanying drawings, it will be understood by those of ordinary skill in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the present disclosure as defined in the appended claims.
