Description

Technical Field

[0001] This invention relates to the field of logistics unloading platform technology, specifically to an adjustable logistics unloading platform and its unloading method. Background Technology

[0002] The deepening trend of globalization has driven the development of international trade. With the expansion of global supply chain networks, the demand for transporting goods from manufacturing sites to sales destinations has increased significantly. This demand is not only reflected in consumer goods but also includes industrial raw materials and components. In this context, logistics has become a key element connecting all links of the supply chain, directly impacting the efficiency and cost of goods circulation. The rise of e-commerce has dramatically changed traditional logistics models. E-commerce platforms like Alibaba and Amazon rely on efficient logistics systems to meet the demand for fast and accurate delivery. Last-mile delivery has become a key area of ​​logistics development, with express delivery and same-city delivery services expanding 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 are driving the intelligent transformation of logistics.

[0003] Modern logistics centers, distribution centers, and warehouses place higher demands on unloading platforms. With the rapid development of e-commerce, express delivery, and new retail, logistics facilities need to handle more diverse goods, especially large and heavy items. Traditional manual unloading methods are no longer sufficient to meet efficiency and safety requirements; therefore, automated and standardized unloading platforms have emerged. Processing efficiency: With increasing transport volume and delivery frequency, unloading efficiency has become a crucial factor determining the efficiency of logistics operations. Flexibility: Different types of vehicles and goods require unloading platforms of different specifications and configurations, necessitating a degree of adjustability. Logistics unloading platforms are typically built outside warehouse buildings, directly connected to the truck loading and unloading area. To ensure efficient and safe loading and unloading processes, the design and structural technology of unloading platforms are continuously optimized, including the following aspects: Height adjustment technology: Due to varying truck bed heights, unloading platforms typically employ hydraulic lifting systems or mechanical adjustment systems to match the height of different vehicles. Leveling adjustment and cushioning design: Gaps and unevenness between the unloading platform and the vehicle can lead to goods falling or being damaged.

[0004] Because the height of a logistics warehouse is fixed, while the height of different truck beds varies, when the logistics platform is raised or lowered for adjustment, the transport device at the other end will be affected and move further away from the warehouse, resulting in reduced unloading efficiency.

[0005] In view of the above, in order to overcome the above technical problems, the present invention designs an adjustable logistics unloading platform and its unloading method, thereby solving the above technical problems. Summary of the Invention

[0006] The technical objective of this invention is to design an adjustable logistics unloading platform and its unloading method. When the logistics platform is raised or lowered due to different cargo box heights, the length of the conveying device is adjusted so that its horizontal length on the ground remains constant. This allows it to be fixedly installed in the initial section of the logistics warehouse conveying device, thereby improving transportation efficiency.

[0007] To achieve the above-mentioned technical objectives, the present invention provides the following technical solution:

[0008] This adjustable logistics unloading platform is a device specifically designed for modern logistics loading and unloading needs. Its structure includes a fixed base, lifting mast, logistics platform, transport mechanism, connecting mechanism, and transition components. It aims to improve loading and unloading efficiency, ensure safety, and adapt to various logistics scenarios. The following is a detailed description of the platform's structure and functions:

[0009] The fixed base is the basic structure of the entire unloading platform. Installed on the ground in the logistics unloading area, it 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 weight of goods and equipment, but also resist the impact force generated by vehicles during loading and unloading.

[0010] The lifting boom is mounted on top of a fixed base and features adjustable height. Utilizing a hydraulic or electric lifting device, it automatically adjusts the height of the logistics platform to accommodate different truck bed heights for docking. This adjustment function solves the problem of fixed height in traditional unloading platforms, effectively improving applicability and ease of operation, and is suitable for various types of vehicles (such as box trucks, refrigerated trucks, and flatbed trucks). The adjustment range of the lifting boom is designed to fully consider the height differences of different transport vehicles, ensuring a smooth and efficient loading and unloading process.

[0011] The logistics platform, located atop the lifting mast, is the main working area for unloading operations. Designed with a non-slip structure and covered with wear-resistant, anti-slip material, it ensures worker safety even in wet environments. The platform's dimensions and load-bearing capacity are designed to meet the needs of different logistics centers, accommodating the loading and unloading of bulk goods or heavy equipment. The platform possesses a certain level of vibration resistance and load-bearing capacity, effectively resisting impacts during loading and unloading.

[0012] The transport mechanism is installed at an angle on the side of the logistics platform, facilitating the smooth transfer of goods from the truck bed to the platform. An adjustable component within the transport mechanism allows for automatic length adjustment via control buttons, accommodating different truck bed sizes that require varying platform heights. This design enhances the flexibility of the logistics platform, enabling efficient loading and unloading within limited spaces, making it suitable for narrow unloading areas or high-frequency loading / unloading environments.

[0013] The connecting mechanism is installed inside the transport mechanism and is mainly used to connect and secure adjacent transport mechanisms. This structure automatically locks itself using a worm gear self-locking principle when the transport mechanisms are extended, ensuring a stable connection between the two transport mechanisms during deployment and preventing goods from falling or platform instability. The connecting mechanism can be quickly adjusted during deployment and retraction, allowing operators to use it flexibly in different loading and unloading scenarios.

[0014] The transition assembly, mounted above the connecting mechanism, provides continuous support for the cargo when the mechanism is extended. Employing a flexible support structure, the transition assembly automatically springs up when the platform unfolds, creating a smooth transition surface that facilitates the sliding of cargo from the truck bed onto the logistics platform, preventing damage due to height differences. This design not only improves loading and unloading efficiency but also protects fragile or irregularly shaped goods, reducing breakage rates.

[0015] The transport mechanism comprises multiple parts, including a transport plate, transport rollers, telescopic grooves, limit rods, adjustment components, and operating buttons, featuring a compact design and diverse functions. Specifically, the transport plate, as the main body of the transport mechanism, bears the goods and provides a stable surface, exhibiting good wear resistance and load-bearing capacity. Transport rollers are installed above the transport plate, reducing friction between the goods and the platform through rolling, facilitating the sliding of goods on the platform, thereby improving loading and unloading efficiency. Telescopic grooves are formed on the side of the transport plate for installing and adjusting the connecting mechanism. Limit rods are located above the telescopic grooves, serving to fix and limit the movement of the connecting mechanism, helping to maintain stability. Adjustment components installed on the side are responsible for adjusting the exposed length and angle of the connecting mechanism to adapt to different carriage heights and sizes. The operating buttons are installed on the top of the transport plate, allowing operators to control the adjustment components via buttons, further enhancing ease of use and safety.

[0016] The adjustment assembly comprises key components such as a micro motor, a rotating worm gear, a mating worm wheel, and an adjusting gear, exhibiting a compact and ingenious design. First, the micro motor, a bidirectional rotating motor capable of both forward and reverse rotation, meets adjustment requirements in different directions. The output of the micro motor is connected to the rotating worm gear; when the motor starts, the worm gear rotates accordingly, producing a precise transmission effect. A mating worm wheel is mounted on the side of the rotating worm gear; the worm gear and worm wheel mesh with each other, and the worm wheel rotates under the drive of the worm gear, completing the force transmission process. An adjusting gear is mounted below the worm wheel; its main function is to rotate coaxially with the worm wheel, thereby pushing the connecting plate through adjusting tooth holes, further refining and controlling the adjustment action to achieve length and angle adjustments of the transport mechanism. Through this design, the adjustment assembly can precisely control the extension and adjustment of the connecting mechanism, ensuring the stability and operational flexibility of the loading and unloading process, significantly improving the efficiency and safety of the unloading platform.

[0017] The adjusting gear and the rotating worm are coaxially arranged, ensuring synchronous rotation and stability and precision in the transmission process. Thanks to the self-locking characteristic between the worm gear and the worm, the transition plate cannot push the adjusting gear to rotate in the opposite direction when the system is subjected to external force, thus achieving the system's self-locking function. This design effectively prevents the transport plate from loosening or accidentally moving during adjustment, improving the safety and reliability of the device and ensuring stable operation during loading and unloading.

[0018] The connecting mechanism comprises a connecting plate, positioning holes, spring holes, and adjusting gear holes. Its overall structure is compact and functionally defined, enabling stable connection and flexible adjustment. Specifically, the connecting plate, as the main body of the connecting mechanism, is made of high-strength alloy material and installed inside the transport mechanism. It possesses excellent wear resistance and impact resistance, capable of withstanding repeated operations and cargo impacts. A positioning hole is located in the center of the connecting plate, its main function being to accurately position and fix related components, ensuring structural stability during loading and unloading. Multiple spring holes are evenly distributed around the positioning hole; these holes are used to install spring sleeves, which provide elastic support after installation, enhancing the stability of the transition components. Furthermore, a series of adjusting gear holes are located on the sides of the connecting plate, used to engage with adjusting gears for locking and adjustment, achieving precise adjustment of length and angle during docking. This structural design not only improves the reliability of the connecting mechanism but also allows it to adapt to various loading and unloading needs, significantly enhancing its flexibility.

[0019] The horizontal cross-sectional shape of the adjusting tooth hole is trapezoidal. This trapezoidal design improves the tightness of the engagement and the smoothness of rotation. The trapezoidal structure creates a self-locking effect, and its varying width provides a larger contact area during engagement, increasing friction and thus enhancing the tight fit between the connecting plate and the gear, reducing the risk of loosening and improving system stability. The trapezoidal cross-section design effectively guides the gear meshing process, reducing frictional resistance and jamming, making the rotation of the adjusting component smoother. Simultaneously, this design reduces gear wear-related jamming problems during rotation, extending the service life of the connecting mechanism. The trapezoidal tooth hole design more evenly distributes load pressure, reducing stress concentration at the tooth hole edges, decreasing the probability of material fatigue and damage, and further enhancing the durability and safety of the adjusting component.

[0020] The connecting mechanism further includes a telescopic block, a limiting groove, and a movable groove, with refined design details and significantly enhanced functionality. Specifically, the telescopic block is installed on both sides of the connecting plate and is made of high-strength material, possessing good compressive resistance and capable of withstanding the tensile and compressive stresses generated during cargo loading and unloading. A limiting groove is provided above the telescopic block, with a semi-circular cross-sectional shape. This design effectively guides the sliding of the limiting rod while reducing friction, ensuring the stability of the telescopic block during movement. The semi-circular structure of the limiting groove also provides a certain buffering effect, preventing component damage due to excessive displacement. A movable groove is formed on the inner side of the telescopic block, accommodating the adjusting rod or other moving parts, providing sufficient space for flexible adjustment. This allows the connecting mechanism to adapt to different loading and unloading scenarios and adjustment needs, improving the overall structural flexibility and adaptability.

[0021] The transition assembly comprises a transition plate, transition rollers, movable plates, positioning shafts, and spring sleeves. Its precise structural design effectively improves the continuity and stability of cargo loading and unloading. Firstly, the transition plate, as the main body of the assembly, is installed above the connecting mechanism, serving as both a connector and support. It is made of a wear-resistant alloy, offering high impact resistance and durability. The transition rollers, mounted on the surface of the transition plate, reduce friction between the cargo and the plate, facilitating smooth cargo sliding and minimizing damage caused by friction. The movable plates, located on both sides of the transition plate, can be adjusted according to the size and shape of the cargo, providing additional support and protection to prevent cargo from sliding or falling.

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

[0023] An adjustable logistics unloading method is provided, which is used in conjunction with the aforementioned adjustable logistics unloading platform; the steps of the method are as follows:

[0024] S1: Staff members use pneumatic or hydraulic methods to raise the lifting bar, thus raising the logistics platform to the high working position.

[0025] S2: When the operator presses the operation button, the micro motor receives the instruction and starts to rotate. One end of the micro motor is installed on the rotating worm gear, which rotates in the forward direction, driving the worm wheel to rotate.

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

[0027] S4: Once the connecting plate is fully exposed, the spring in the spring sleeve will pop out the transition plate, at which point the transition assembly is located between the two transport mechanisms, thus extending the transport route.

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

[0029] 1. This invention, through the ingenious design of the transport and connecting mechanisms, integrates multiple functions such as height adjustment, length adjustment, automatic connection, and flexible transition. This allows the equipment to flexibly adapt to different logistics loading and unloading environments, solving problems such as inconvenience, low efficiency, and safety hazards commonly found in traditional loading and unloading methods. Specifically, the system uses adjusting components to drive the connecting mechanism, enabling flexible adjustment of the transport mechanism's length to meet transport needs of different heights and sizes. During loading and unloading, the system automatically adjusts the height of the transport mechanism to accommodate vehicles and warehouse platforms of varying heights. Simultaneously, through the cooperation of the connecting mechanism, the horizontal length of the transport mechanism remains constant during platform lifting and lowering, avoiding the instability caused by height changes in traditional equipment. Thus, during the ascent of the logistics platform, the tail end of the transport mechanism is fixedly connected to the head end of the logistics warehouse transport system, forming a stable transport channel and ensuring seamless connection between the transport equipment and the warehouse system. The core advantage of this design is its ability to achieve fully automated transport, reducing the need for manual operation. Traditional logistics loading and unloading operations typically rely on manual docking, which is not only inefficient but also prone to operational errors, leading to equipment damage or transport interruptions. This invention, through its automated connection and adjustment functions, enables precise docking between transportation agencies and logistics warehouse systems, greatly improving loading and unloading efficiency and accuracy, reducing manual intervention, and lowering operational risks.

[0030] 2. This invention is highly adaptable, capable of meeting the needs of different types of transport vehicles and goods. Whether it's a vehicle of varying height or cargo of different specifications, automatic adjustment of height and length ensures stability and safety during transport. The flexible transition components further enhance smoothness during loading and unloading, reducing potential impacts and damage. Through this invention, the loading and unloading efficiency of logistics centers is significantly improved, while substantially reducing the intensity and cost of manual operations. This innovative design not only improves operational efficiency but also effectively enhances the safety and adaptability of the transportation system, making it suitable for various complex logistics environments.

[0042] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions 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 specifically designed for modern logistics loading and unloading needs. Its structure includes a fixed base 1, a lifting rod 2, a logistics platform 3, a transport mechanism 4, a connecting mechanism 5, and transition components 6. It aims to improve loading and unloading efficiency, ensure safety, and adapt to various logistics scenarios. The following is a detailed description of the platform's structure and functions:

[0044] The fixed base 1 is the basic structure of the entire unloading platform. It is installed on the ground in 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 bear the weight of goods and equipment, but also withstand the impact force generated by vehicles during loading and unloading.

[0045] The lifting boom 2 is installed on the upper part of the fixed base 1 and has an adjustable height. The lifting boom 2 uses a hydraulic or electric lifting device, which can automatically adjust the height of the logistics platform 3 according to the height of different truck beds to achieve docking. This adjustment function solves the problem of the fixed height of traditional unloading platforms, effectively improving applicability and ease of operation, and is suitable for various types of vehicles (such as box trucks, refrigerated trucks, and flatbed trucks). The adjustment range of the lifting boom 2 is designed to fully consider the height differences of different transport vehicles, ensuring a smooth and efficient loading and unloading process.

[0046] Logistics platform 3 is the main working area for unloading operations, installed on top of lifting boom 2. The platform is designed with a non-slip structure, and its surface is covered with wear-resistant and non-slip material, ensuring the safety of workers even in wet environments. The dimensions and load-bearing capacity of 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 degree of vibration resistance and load-bearing capacity, effectively resisting the impact forces during loading and unloading.

[0047] The transport mechanism 4 is installed at an angle on the side of the logistics platform 3, facilitating the smooth transfer of goods from the truck bed to the platform. The transport mechanism 4 includes an adjustment component 45, whose length can be automatically adjusted via an operating button 46 to accommodate different sized truck beds, requiring the logistics platform 3 to be at varying heights. This design enhances the flexibility of the logistics platform 3, enabling efficient loading and unloading within limited spaces, and is suitable for narrow unloading areas or high-frequency loading and unloading environments.

[0048] The connecting mechanism 5 is installed inside the transport mechanism 4 and is mainly used to connect and secure adjacent transport mechanisms 4. This structure automatically locks itself when the transport mechanism 4 is extended using the self-locking principle of a worm gear, ensuring a stable connection between the two transport mechanisms 4 during deployment and preventing goods from falling or the platform from becoming unstable. The connecting mechanism 5 can be quickly adjusted during deployment and retraction, allowing operators to use it 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 extended. The transition component 6 adopts a flexible support structure, which automatically springs up when the platform is deployed to form a smooth transition surface, facilitating the sliding of goods from the truck bed into the logistics platform 3 and preventing 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, reducing the breakage rate.

[0050] like Figure 3 As shown, the transport mechanism 4 comprises multiple parts, including a transport plate 41, transport rollers 42, a telescopic groove 43, a limiting rod 44, an adjusting assembly 45, and an operation button 46. It features a compact design and diverse functions. Specifically, the transport plate 41, as the main body of the transport mechanism 4, bears the goods and provides a stable surface, exhibiting good wear resistance and load-bearing capacity. The transport rollers 42 are installed above the transport plate 41, reducing friction between the goods and the platform through rolling, facilitating the sliding of goods on the platform, thereby improving loading and unloading efficiency. A telescopic groove 43 is formed on the side of the transport plate 41 for installing and adjusting the connecting mechanism 5. The limiting rod 44 is located above the telescopic groove 43, serving to fix and limit the movement of the connecting mechanism 5, helping to maintain stability. The adjusting assembly 45, installed on the side, adjusts the exposed length and angle of the connecting mechanism 5 to adapt to different carriage heights and sizes. The operation button 46 is installed on the top of the transport plate 41, allowing operators to control the adjusting assembly 45 via the button, further enhancing ease of use and safety.

[0051] like Figure 4-5 As shown, the adjustment assembly 45 includes key components such as a micro motor 451, a rotating worm gear 452, a mating worm wheel 453, and an adjusting gear 454, exhibiting a compact structure and ingenious design. First, the micro motor 451 is installed inside the transport plate 41. This motor is a bidirectional rotating motor, capable of rotating in both directions to meet adjustment needs in different directions. The output end of the micro motor 451 is connected to the rotating worm gear 452. When the motor starts, the worm gear rotates accordingly, producing a precise transmission effect. A mating worm wheel 453 is installed on the side of the rotating worm gear 452. The worm gear and worm wheel mesh with each other, and the worm wheel rotates under the drive of the worm gear, completing the force transmission process. Below the worm wheel is an adjusting gear 454, whose main function is to rotate coaxially with the worm wheel, thereby pushing the connecting plate 51 through the adjusting tooth hole 54, further refining and controlling the adjustment action, and realizing the length and angle adjustment of the transport mechanism 4. Through this design, the adjustment component 45 can precisely control the extension and adjustment of the connecting mechanism 5, ensuring the stability of the loading and unloading process and the flexibility of operation, and greatly improving the efficiency and safety of the unloading platform.

[0052] The adjusting gear 454 and the rotating worm 452 are coaxially arranged, which enables synchronous rotation of the two, ensuring the stability and accuracy of the transmission process. Thanks to the self-locking characteristic between the worm gear 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, thus achieving the system's self-locking function. This design effectively prevents the transport plate 41 from loosening or accidentally moving during adjustment, improving the safety and reliability of the device and ensuring stable operation during loading and unloading.

[0053] like Figure 6 As shown, the connecting mechanism 5 includes a connecting plate 51, a positioning hole 52, a spring hole 53, and an adjusting gear hole 54. The overall structure is compact and functionally clear, enabling stable connection and flexible adjustment. Specifically, the connecting plate 51, as the main body of the connecting mechanism 5, is made of high-strength alloy material and installed inside the transport mechanism 4. It has good wear resistance and impact resistance, and can withstand repeated operations and cargo impacts. The connecting plate 51 has a positioning hole 52 in the middle, which is mainly used for precise positioning and fixing of related components, ensuring structural stability during loading and unloading. Multiple spring holes 53 are evenly distributed around the positioning hole 52. These holes are used to install spring sleeves 65, which provide elastic support after installation, enhancing the stability of the transition component 6. In addition, the side of the connecting plate 51 has a series of adjusting gear holes 54, used to lock and adjust with the adjusting gear 454, achieving precise adjustment of length and angle during docking. This structural design not only improves the reliability of the connecting mechanism 5 but also enables it to adapt to various loading and unloading needs, significantly enhancing its flexibility.

[0054] The horizontal cross-sectional shape of the adjusting tooth hole 54 is trapezoidal. This trapezoidal design improves the tightness of the engagement and the smoothness of rotation. The trapezoidal structure creates a self-locking effect, and its varying width provides a larger contact area during engagement, increasing friction and thus enhancing the tight fit between the connecting plate 51 and the gear, reducing the risk of loosening and improving system stability. The trapezoidal cross-section design effectively guides the gear meshing process, reducing frictional resistance and jamming, making the rotation of the adjusting component 45 smoother. Simultaneously, this design reduces gear wear-related jamming problems during rotation, extending the service life of the connecting mechanism 5. The trapezoidal tooth hole design more evenly distributes load pressure, reducing stress concentration at the tooth hole edges, decreasing the probability of material fatigue and damage, and further enhancing the durability and safety of the adjusting component 45.

[0055] The connecting mechanism 5 further includes a telescopic block 55, a limiting groove 56, and a movable groove 57, with refined design details and significantly enhanced functionality. Specifically, the telescopic block 55 is installed on both sides of the connecting plate 51, made of high-strength material, and has good compressive strength, capable of withstanding the tensile and compressive stresses generated during cargo loading and unloading. A limiting groove 56 is provided above the telescopic block 55, with a semi-circular cross-sectional shape. This design effectively guides the sliding of the limiting rod 44 while reducing friction, ensuring the stability of the telescopic block 55 during movement. The semi-circular structure of the limiting groove 56 also provides a certain buffering effect, preventing component damage due to excessive displacement. A movable groove 57 is provided on the inner side of the telescopic block 55. The movable groove 57 is used to accommodate the adjusting rod or other moving parts, providing sufficient space for flexible adjustment, enabling the connecting mechanism 5 to adapt to different loading and unloading scenarios and adjustment needs, improving the overall structural flexibility and adaptability.

[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. Its precise structural design effectively improves the continuity and stability of cargo loading and unloading. Firstly, the transition plate 61, as the main body of the transition assembly 6, is installed above the connecting mechanism 5, serving as a connector and support. It is made of a wear-resistant alloy, possessing high impact resistance and durability. The transition roller shaft 62, installed on the surface of the transition plate 61, reduces friction between the cargo and the plate surface, facilitating smooth cargo sliding and minimizing damage caused by friction. The movable plates 63 are located on both sides of the transition plate 61 and can be adjusted according to the size and shape of the cargo, providing additional support and protection to prevent cargo from sliding or falling.

[0057] In addition, the transition assembly 6 also includes a positioning shaft 64 and a spring sleeve 65. 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 surrounds the positioning shaft 64 and, utilizing the elastic buffering characteristics of the spring, effectively absorbs the impact force generated when the cargo is pressed down, 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 provided, which is used in conjunction with the aforementioned adjustable logistics unloading platform; the steps of the method are as follows:

[0059] S1: Staff members adjust the lifting rod 2 to rise using pneumatic or hydraulic methods, so that the logistics platform 3 rises to the high working point;

[0060] S2: When the operator presses the operation button 46, the micro motor 451 receives the instruction and starts to rotate. One end of the micro motor 451 is installed on the rotating worm gear 452 and rotates in the forward direction, driving the worm wheel 453 to rotate.

[0061] S3: The adjusting gear 454 and the mating worm gear 453 rotate coaxially, so that the connecting plate 51, which is engaged with the adjusting gear 454 through the adjusting tooth hole 54, begins to be exposed.

[0062] S4: When the connecting plate 51 is fully exposed, the spring in the spring sleeve 65 will pop out the transition plate 61, at which point the transition component 6 is located in the middle of the two transport mechanisms 4, thus extending the transport route.

[0063] During operation, the staff adjusts the lifting rod 2 to rise using pneumatic or hydraulic methods, thereby raising the logistics platform 3 to the high working position.

[0064] When the operator presses the operation button 46, the micro motor 451 receives the instruction and starts to rotate. One end of the micro motor 451 is installed on the rotating worm gear 452, which rotates in the forward direction, driving the mating worm wheel 453 to rotate. The adjusting gear 454 rotates coaxially with the mating worm wheel 453, so the connecting plate 51, which is engaged with the adjusting gear 454 through the adjusting tooth hole 54, begins to be exposed. During the process of the connecting plate 51 sliding from the transport mechanism 4, the limiting rod 44 and the limiting groove 56 maintain its motion stability.

[0065] Once the connecting plate 51 is fully exposed, the spring in the spring sleeve 65 ejects the transition plate 61. The movable plate 63 is intercepted by the movable groove 57, keeping the transition plate 61 stable. The goods pass from the transport plate 41, through the transition plate 61, and then through the adjacent transport plate 41. At this point, the transition assembly 6 is located between the two transport mechanisms 4, extending the transport route. During this process, the bottom of the goods contacts the transport roller and the transition roller 62, and the goods are quickly transported to the logistics warehouse by rolling.

Therefore, this disclosure is not limited to the examples and designs described herein, but should be given the broadest scope consistent with the principles and novel features disclosed herein.
