Description

Technical Field

[0001] This utility model relates to the technical field of logistics unloading auxiliary equipment, and in particular to a logistics loading and unloading device. Background Technology

[0002] Currently, there are two main methods for unloading plastic products in the automotive parts logistics industry. The first method involves using a forklift to unload a fully loaded trolley from the truck bed, manually removing or moving the plastic products from the trolley, and then using a forklift to move the plastic products from the ground onto the tractor. This method requires the use of forklifts, increasing the risk of contact between people and vehicles and is inefficient. The second method involves setting up a platform at the same height as the tractor at the parts unloading yard, using manual labor to push the trolley from the tractor to unload the goods, and then manually pushing the empty trolley back into the tractor after all the plastic products have been processed. This method requires manual handling of the trolley up and down the ramp to the unloading platform, posing a risk of the trolley tipping over and is also inefficient.

[0003] Therefore, how to eliminate safety risks in operations is an urgent problem that needs to be solved. Utility Model Content

[0004] The main purpose of this utility model is to propose a logistics loading and unloading device, which aims to solve the problem of how to eliminate safety risks in operation.

[0009] In one embodiment, the first drive assembly further includes a first pedal, a first pull rope, and a first trolley. A first slide rail is provided on the base, the first slide rail extends horizontally, the first trolley slides in cooperation with the first slide rail, the first pedal is hinged to the base, one end of the first pull rope is connected to the first pedal, and the other end of the first pull rope is connected to the first trolley. The first pedal can drive the first trolley and the first lower connecting rod to move relative to the first slide rail through the first pull rope, so that the first upper connecting rod can move from the first support position to the first folding position.

[0010] In one embodiment, the second drive assembly further includes a second spring balancer. The support frame includes a crossbar and a second rotating sleeve. The crossbar is slidably engaged with the upright and is located below the frame body. The frame body can abut against the crossbar. The second rotating sleeve is connected to the crossbar.

One end of the second spring balancer is connected to the upright, and the other end of the second spring balancer is connected to the second rotating sleeve. The second spring balancer can provide an upward force for the second rotating sleeve.

[0011] In one embodiment, the second drive assembly further includes a second pedal, a second pull rope, and a second trolley. The base is also provided with a second slide rail, which extends horizontally. The second trolley slides in cooperation with the second slide rail. The second pedal is hinged to the base. One end of the second pull rope is connected to the second pedal, and the other end of the second pull rope is connected to the second trolley. The second pedal can drive the second trolley and the second lower connecting rod to move relative to the second slide rail through the second pull rope, so that the second upper connecting rod can move from the second support position to the second folding position.

[0012] In one embodiment, the position where the first spring balancer is connected to the upright is higher than the position where the first spring balancer is connected to the first rotating sleeve, and the position where the second spring balancer is connected to the upright is higher than the position where the second spring balancer is connected to the second rotating sleeve.

[0013] In one embodiment, the tension of the first spring balancer is less than the weight of the movable frame, and the tension of the second spring balancer is greater than the weight of the support frame.

[0014] In one embodiment, the first drive assembly further includes a handrail connected to the frame body.

[0015] In one embodiment, the movable frame includes a frame body and a material rack. The frame body is slidably engaged with the upright frame, and the support frame is located below the frame body. The frame body can abut against the support frame. The material rack includes a first support rod and a second support rod. Both the first support rod and the second support rod are connected to the frame body. The first support rod and the second support rod are spaced apart in the horizontal direction. The first support rod and the second support rod are used to support materials.

[0016] In one embodiment, there are multiple first support rods, which are spaced apart along the extension direction of the upright, and the number of second support rods is the same as the number of first support rods and they are arranged in a one-to-one correspondence.

[0017] In this embodiment of the utility model, the base is used to support the entire logistics loading and unloading device. Casters are installed on the side of the base away from the upright, allowing the entire logistics loading and unloading device to move flexibly. The movable frame and the support frame are both slidably engaged with the upright, enabling the logistics loading and unloading device to adapt to the loading and unloading needs of materials of different heights and sizes, and has good flexibility and adaptability. The movable frame is used to carry materials, while the support frame is located below the movable frame to support it, thereby enhancing the structural stability, reliability and safety of the entire logistics loading and unloading device when carrying materials. Furthermore, by setting the first drive component and the second drive component, the operator can easily and quickly adjust the position of the movable frame and the support frame to achieve rapid loading and unloading of materials. The structure is simple and the operation is convenient. There is no need for complicated manual operation, which reduces the waiting and adjustment time, improves the convenience and continuity of operation, and makes the entire logistics process smoother. In this embodiment, because the first upper connecting rod has a first support position and a first folding position, and the second upper connecting rod has a second support position and a second folding position, the logistics loading and unloading device can realize three working modes: the highest position mode, the transportation position mode, and the lowest position mode. When the logistics loading and unloading device is in the highest position mode, the first upper connecting rod is located in the first support position, and the first upper connecting rod and the first lower connecting rod extend vertically, forming a 180° angle between them. This allows the first upper connecting rod and the first lower connecting rod to drive the movable frame to slide upward relative to the upright frame to the highest point, facilitating the loading and unloading of materials. At this time, the movable frame is separated from the support frame. When the logistics loading and unloading device is in the transportation position mode, the first upper connecting rod is located in the first folding position, and the first upper connecting rod and the first lower connecting rod are not collinear, meaning the angle between them is less than 180°. The first upper connecting rod and the first lower connecting rod cannot support the movable frame. The movable frame and materials, under their own weight and the weight of the materials, will move downwards relative to the upright frame. The second upper connecting rod is located at the second support position. The second upper and second lower connecting rods extend vertically, forming a 180° angle. This allows the second upper and lower connecting rods to drive the support frame to slide upwards relative to the upright frame to its highest point, thus abutting against the downward-sliding movable frame. The support frame supports the movable frame and materials, thereby enhancing the structural stability of the entire logistics loading and unloading device when carrying materials. The logistics loading and unloading device can be moved via casters. Since the height of the logistics loading and unloading device in the transport position mode is lower than that in the highest position mode, it is easier to observe the working condition during manual transport. Furthermore, the height of the logistics loading and unloading device from the ground in the transport position mode is 92cm, the same as the height of the trolley, eliminating the need for further height adjustment to complete the transfer. When the logistics loading and unloading device is in the lowest position mode, please refer to [link to relevant documentation]. Figure 4The first upper connecting rod is located in the first folding position, and the first upper connecting rod and the first lower connecting rod are not collinear. The second upper connecting rod is located in the second folding position, and the second upper connecting rod and the second lower connecting rod are not collinear. That is, the included angle between the first upper connecting rod and the first lower connecting rod is less than 180°, and the included angle between the second upper connecting rod and the second lower connecting rod is less than 180°. At this time, the second upper connecting rod and the second lower connecting rod cannot support the support frame, the movable frame and the material. Under the action of their own weight and the weight of the material, the support frame and the movable frame will move downward relative to the upright to the lowest point. At this time, the height of the support frame from the ground is 60cm, which facilitates loading and unloading of materials. This utility model embodiment, by employing a first drive component and a second drive component, allows for quick and flexible adjustment of the positions of the movable frame and support frame, enabling operators to easily perform material loading and unloading operations. Its simple structure eliminates the need for complex operating procedures, simplifying work steps, improving operational convenience, significantly shortening loading and unloading time, increasing operational efficiency, and reducing reliance on traditional forklifts and other equipment. It eliminates the high-risk operation of using forklifts to pick up materials 50 times / day and the low-efficiency operation of manually pushing trolleys, reducing safety risks caused by improper operation and the frequency of direct human involvement in loading and unloading operations, thereby lowering the probability of workplace accidents and improving operational safety. Compared to the traditional method of manually pushing trolleys, it eliminates the unloading and turnover of trolleys, only unloading materials, reducing labor intensity. It also eliminates the need for dedicated unloading areas or platforms with height differences, enabling workpiece turnover in the logistics operation area with minimal space, saving logistics space, and eliminating problems of insufficient unloading area and operational restrictions. Furthermore, the logistics loading and unloading device has a simple structure, high stability, reduces the risk of material damage during loading and unloading, and lowers maintenance costs.

[0032] Currently, there are two main methods for unloading plastic products in the automotive parts logistics industry. The first method involves using a forklift to unload a fully loaded trolley from the truck bed, manually removing or moving the plastic products from the trolley, and then using a forklift to move the plastic products from the ground onto the tractor. This method requires the use of forklifts, increasing the risk of contact between people and vehicles and is inefficient. The second method involves setting up a platform at the same height as the tractor at the parts unloading yard, using manual labor to push the trolley from the tractor to unload the goods, and then manually pushing the empty trolley back into the tractor after all the plastic products have been processed. This method requires manual handling of the trolley up and down the ramp to the unloading platform, posing a risk of the trolley tipping over and is also inefficient.

[0033] After careful research, the applicant found that the first method, using forklifts for picking operations, requires frequent forklift operations by the forklift driver, increasing the risk of contact between people and vehicles, potentially leading to forklift accidents and personal injuries. The manual handling of plastic products is time-consuming and labor-intensive, resulting in low overall operational efficiency. This method involves multiple steps of forklift operation and manual handling, increasing operational complexity and high dependence on forklifts. If a forklift malfunctions or requires maintenance, it will disrupt the entire workflow. Furthermore, the use and maintenance of forklifts incur additional costs, increasing the total cost of logistics operations. The second method, setting up a platform at the same height as the towing vehicle and manually pushing the trolley up and down the ramp to the unloading platform, carries the risk of the trolley tipping over during operation, potentially damaging goods or causing personal injury. Manually moving the trolley up and down the ramp is labor-intensive, easily leading to worker fatigue and injury. The process of manually pushing the trolley to unload and retrieving empty trolleys is time-consuming and inefficient, impacting overall logistics efficiency. Moreover, it requires sufficient space to set up a platform at the same height as the towing vehicle, which is a limitation for unloading yards with limited space.

[0034] The main purpose of this utility model is to propose a logistics loading and unloading device to solve the problem of how to eliminate safety risks in operation.

[0035] Please see Figures 1 to 4 In one embodiment of this utility model, the logistics loading and unloading device 100 includes a frame 1, a movable frame 2, a support frame 3, casters 4, a first drive assembly 5, and a second drive assembly 6. The frame 1 includes a base 11 and a vertical frame 12. The base 11 is connected to the vertical frame 12. Casters 4 are provided on the side of the base 11 away from the vertical frame 12. The movable frame 2 and the support frame 3 are both slidably engaged with the vertical frame 12, and the support frame 3 is located below the movable frame 2. The movable frame 2 can abut against the support frame 3. The movable frame 2 is used to carry materials. The first drive assembly 5 includes a first upper connecting rod 51 and a first lower connecting rod 52 rotatably connected. The end of the first lower connecting rod 52 away from the first upper connecting rod 51 is rotatably mounted on the base 11, and the end of the first upper connecting rod 51 away from the first lower connecting rod 52 is rotatably mounted on the movable frame 2. The first upper connecting rod 51 has a first support position 511 and a first folding position. 512; The first upper link 51 is located at the first support position 511, and the first upper link 51 and the first lower link 52 extend in the vertical direction; the first upper link 51 is located at the first folding position 512, and the first upper link 51 and the first lower link 52 are not collinearly arranged; the second drive assembly 6 includes a second upper link 61 and a second lower link 62 rotatably connected, the end of the second lower link 62 away from the second upper link 61 is rotatably mounted on the base 11, and the end of the second upper link 61 away from the second lower link 62 is rotatably mounted on the support frame 3, the second upper link 61 has a second support position 611 and a second folding position 612; the second upper link 61 is located at the second support position 611, and the second upper link 61 and the second lower link 62 extend in the vertical direction; the second upper link 61 is located at the second folding position 612, and the second upper link 61 and the second lower link 62 are not collinearly arranged.

[0036] In this embodiment of the utility model, the base 11 is used to support the entire logistics loading and unloading device 100. The side of the base 11 away from the upright 12 is equipped with casters 4, which allows the entire logistics loading and unloading device 100 to move flexibly. The movable frame 2 and the support frame 3 are both slidably engaged with the upright 12, so that the logistics loading and unloading device 100 can adapt to the loading and unloading needs of materials of different heights and sizes, and has good flexibility and adaptability. The movable frame 2 is used to carry materials, while the support frame 3 is located below the movable frame 2 to support the movable frame 2, thereby enhancing the structural stability, reliability and safety of the entire logistics loading and unloading device 100 when carrying materials. In addition, by setting the first drive component 5 and the second drive component 6, the operator can easily and quickly adjust the position of the movable frame 2 and the support frame 3 to achieve rapid loading and unloading of materials. The structure is simple and the operation is convenient. There is no need for complicated manual operation, which reduces the waiting and adjustment time, improves the convenience and continuity of operation, and makes the entire logistics process smoother.In this embodiment, since the first upper connecting rod 51 has a first support position 511 and a first folding position 512, and the second upper connecting rod 61 has a second support position 611 and a second folding position 612, the logistics loading and unloading device 100 can realize three working modes, namely the highest position mode, the transportation position mode, and the lowest position mode: when the logistics loading and unloading device 100 is in the highest position mode, the first upper connecting rod 51 is located at the first support position 511, and the first upper connecting rod 51 and the first lower connecting rod 52 extend in the vertical direction, that is, the first upper connecting rod 51... The first upper link 51 and the first lower link 52 form a 180° angle, allowing the first upper link 51 and the first lower link 52 to drive the movable frame 2 to slide upward relative to the upright frame 12 to its highest position, thus facilitating loading and unloading of materials. At this time, the movable frame 2 is separated from the support frame 3. When the logistics loading and unloading device 100 is in the transport position mode, the first upper link 51 is located in the first folding position 512, and the first upper link 51 and the first lower link 52 are not collinear, that is, the angle between the first upper link 51 and the first lower link 52 is less than 180°. Link 52 cannot support the movable frame 2 and the material. Under the combined weight of its own weight and the weight of the material, the movable frame 2 will move downward relative to the upright frame 12. The second upper link 61 is located at the second support position 611. The second upper link 61 and the second lower link 62 extend vertically, forming a 180° angle between them. This allows the second upper link 61 and the second lower link 62 to drive the support frame 3 to slide upward relative to the upright frame 12 to its highest point, thus abutting against the downward sliding movable frame 2. The support frame 3 is used to support the movable frame 2 and the material. The material is loaded, thus enhancing the structural stability of the entire logistics loading and unloading device 100 when carrying materials. At this time, the logistics loading and unloading device 100 can be moved by the casters 4. Since the height of the logistics loading and unloading device 100 in the transport position mode is lower than that in the highest position mode, it is easier to observe the working condition during manual transport. In addition, the height of the logistics loading and unloading device 100 from the ground in the transport position mode is 92cm, which is the same as the height of the trolley, so the transfer can be completed without adjusting the height again. When the logistics loading and unloading device 100 is in the lowest position mode, please refer to [the relevant documentation]. Figure 4 The first upper connecting rod 51 is located at the first folding position 512. The first upper connecting rod 51 and the first lower connecting rod 52 are not collinear. The second upper connecting rod 61 is located at the second folding position 612. The second upper connecting rod 61 and the second lower connecting rod 62 are not collinear. That is, the included angle between the first upper connecting rod 51 and the first lower connecting rod 52 is less than 180°, and the included angle between the second upper connecting rod 61 and the second lower connecting rod 62 is less than 180°. At this time, the second upper connecting rod 61 and the second lower connecting rod 62 cannot support the support frame 3, the movable frame 2 and the material. Under the action of their own weight and the weight of the material, the support frame 3 and the movable frame 2 will move downward relative to the upright frame 12 to the lowest position. At this time, the height of the support frame 3 from the ground is 60cm, which facilitates loading and unloading of materials.

[0037] The technical solution of this utility model, by employing a first drive component 5 and a second drive component 6, allows for quick and flexible adjustment of the positions of the movable frame 2 and the support frame 3, enabling operators to easily perform material loading and unloading operations. The structure is simple, requiring no complex operating procedures, simplifying the work steps, improving operational convenience, significantly shortening loading and unloading time, increasing work efficiency, reducing reliance on traditional forklifts and other equipment, and eliminating the high-risk operation of using forklifts to pick up materials 50 times / day and the low-efficiency operation of manually pushing the trolley. This reduces safety risks caused by improper operation and also reduces manual labor. The frequency of participation in loading and unloading operations is reduced, thereby lowering the probability of workplace accidents and improving operational safety. Compared with the traditional method of manually pushing trolleys for turnover, it eliminates the unloading and turnover of trolleys, only unloading materials, reducing the intensity of manual labor. It also eliminates the need to set up a dedicated unloading area or platform with height differences, enabling the turnover of workpieces in the logistics operation area with minimal space, saving logistics space, and eliminating the problems of insufficient unloading area and restricted operation. In addition, the logistics loading and unloading device 100 has a simple structure and high stability, reducing the risk of damage to materials during loading and unloading and lowering maintenance costs.

[0038] In this embodiment, the movable frame 2, support frame 3, upright frame 12, and base 11 can all be made of aluminum alloy tubing, thereby enhancing the strength and structural stability of the logistics loading and unloading device 100. To ensure the stability of the movement of the logistics loading and unloading device 100, there are four casters 4, which are spaced apart on the base 11. All four casters 4 can be rubber casters, providing movement support for the logistics loading and unloading device 100. The casters 4 can also provide a locking function, enabling the logistics loading and unloading device 100 to move and lock in any position, so as to load and unload materials on the logistics tractor car body turnover trolley at any position.

[0039] In this embodiment, since the support frame 3 needs to bear the weight of the movable frame 2 and the materials, in order to improve the structural stability of the logistics loading and unloading device 100, there are two second upper connecting rods 61, and the number of second lower connecting rods 62 is the same as the number of second upper connecting rods 61 and is set one-to-one. By setting two second upper connecting rods 61 and two lower connecting rods 62, the load-bearing capacity of the support frame 3 can be improved, allowing the support frame 3 to bear more weight, thereby enhancing the stability of the entire logistics loading and unloading device 100. During the loading and unloading process, the design of two second upper connecting rods 61 and two lower connecting rods 62 also reduces the risk of materials falling due to the failure of a single second upper connecting rod 61 and second lower connecting rod 62, thus improving operational safety.

[0040] Please see Figure 5 and Figure 7In one embodiment, the first drive assembly 5 further includes a first spring balancer 53. The movable frame 2 includes a frame body 21 and a first rotating sleeve 22. The frame body 21 is slidably engaged with the upright frame 12, and the support frame 3 is located below the frame body 21. The frame body 21 can abut against the support frame 3. The first rotating sleeve 22 is connected to the frame body 21. The end of the first upper connecting rod 51 away from the first lower connecting rod 52 is rotatably connected to the first rotating sleeve 22. One end of the first spring balancer 53 is connected to the upright frame 12, and the other end of the first spring balancer 53 is connected to the first rotating sleeve 22. The first spring balancer 53 can provide an upward force for the first rotating sleeve 22. Specifically, the first spring balancer 53 provides an upward force for the first rotating sleeve 22, which helps to reduce the burden on the operator. The reduced force required for operators to lift or move the movable frame 2 makes operation easier, reducing operator fatigue and potential injury caused by prolonged operation. It eliminates the need for electric forklifts, thus removing the risks associated with using them for loading and unloading materials. The first spring balancer 53 allows for faster and smoother lifting and lowering of the movable frame 2, improving loading and unloading efficiency. It also reduces the risk of sudden descent of the movable frame 2 and material falling due to improper operation, enhancing the stability and safety of the entire logistics loading and unloading device 100 during operation. Furthermore, the force provided by the first spring balancer 53 can be adjusted according to the weight of the movable frame 2 and the material, enabling the logistics loading and unloading device 100 to adapt to the loading and unloading needs of materials of different weights. In this embodiment, the first upper connecting rod 51 can be sleeved on the outer wall of the first rotating sleeve 22, thereby realizing the relative rotation of the first upper connecting rod 51 and the first rotating sleeve 22. The first upper connecting rod 51 can also be hinged to the first rotating sleeve 22 to realize the relative rotation of the first upper connecting rod 51 and the first rotating sleeve 22. This embodiment does not limit the specific rotation method of the first upper connecting rod 51 and the first rotating sleeve 22.

[0041] In one embodiment, the first drive assembly 5 further includes a first pedal 54, a first pull rope 55, and a first trolley 56. A first slide rail 111 is provided on the base 11, extending horizontally. The first trolley 56 is slidably engaged with the first slide rail 111. The first pedal 54 is hinged to the base 11. One end of the first pull rope 55 is connected to the first pedal 54, and the other end is connected to the first trolley 56. The first pedal 54 can drive the first trolley 56 and the first lower connecting rod 52 to move relative to the first slide rail 111 via the first pull rope 55, so that the first upper connecting rod 51 can move from the first support position 511 to the first folding position 512. Specifically, through the design of the first pedal 54 and the first pull rope 55, the operator can... The first trolley 56 can be driven to slide in the left and right direction relative to the first slide rail 111 by a simple foot pedal action. The first trolley 56 can hit the first lower connecting rod 52 to make the first lower connecting rod 52 rotate, thereby driving the first upper connecting rod 51 to move from the first support position 511 to the first folding position 512. The operation is simpler, and the design of the first pedal 54 and the first pull rope 55 can quickly respond to the operator's actions, so that the first upper connecting rod 51 can quickly move from the first support position 511 to the first folding position 512, improving the efficiency of loading and unloading operations. The first drive component 5 has a simple structure, low cost, and does not rely on electricity, reducing the operating cost of the logistics loading and unloading device 100 and enhancing the adaptability and durability of the logistics loading and unloading device 100.

[0042] Please see Figure 6 and Figure 7In one embodiment, the second drive assembly 6 further includes a second spring balancer 63. The support frame 3 includes a crossbar 31 and a second rotating sleeve 32. The crossbar 31 is slidably engaged with the upright frame 12 and is located below the frame body 21. The frame body 21 can abut against the crossbar 31. The second rotating sleeve 32 is connected to the crossbar 31. One end of the second upper connecting rod 61 away from the second lower connecting rod 62 is rotatably connected to the second rotating sleeve 32. One end of the second spring balancer 63 is connected to the upright frame 12, and the other end of the second spring balancer 63 is connected to the second rotating sleeve 32. The second spring balancer 63 can be used as a second rotating sleeve. 32 provides an upward force; specifically, the second spring balancer 63 provides an upward force for the second rotating sleeve 32, which helps reduce the force required by the operator when lifting or moving the support frame 3, making operation easier and reducing operator fatigue and potential injury caused by prolonged operation. The second spring balancer 63 can make the lifting and lowering of the movable frame 2 faster and smoother, thereby improving the efficiency of loading and unloading materials, and can also reduce the risk of sudden descent of the support frame 3 due to improper operation, enhancing the stability and safety of the entire logistics loading and unloading device 100 during operation. In this embodiment, the second upper connecting rod 61 can be sleeved on the outer wall of the second rotating sleeve 32, thereby realizing the relative rotation of the second upper connecting rod 61 and the second rotating sleeve 32. The second upper connecting rod 61 can also be hinged to the second rotating sleeve 32 to realize the relative rotation of the second upper connecting rod 61 and the second rotating sleeve 32. This embodiment does not limit the specific rotation method of the second upper connecting rod 61 and the second rotating sleeve 32.

[0043] In this embodiment, both the frame body 21 and the crossbar 31 can be sleeved on the outer wall of the upright 12, allowing the frame body 21 and the crossbar 31 to slide up and down relative to the upright 12. The frame body 21 and the crossbar 31 can also be provided with a first pulley and a second pulley, which are located on both sides of the upright 12 respectively, and the first pulley and the second pulley can slide relative to the upright 12, thereby allowing the frame body 21 and the crossbar 31 to slide up and down relative to the upright 12. This embodiment does not limit the sliding engagement method between the frame body 21 and the crossbar 31 and the upright 12.

[0044] In one embodiment, the second drive assembly 6 further includes a second pedal 64, a second pull rope 65, and a second trolley 66. A second slide rail 112 is also provided on the base 11, extending horizontally. The second trolley 66 is slidably engaged with the second slide rail 112. The second pedal 64 is hinged to the base 11. One end of the second pull rope 65 is connected to the second pedal 64, and the other end is connected to the second trolley 66. The second pedal 64 can drive the second trolley 66 and the second lower connecting rod 62 to move relative to the second slide rail 112 via the second pull rope 65, so that the second upper connecting rod 61 can move from the second support position 611 to the second folding position 612. Specifically, through the design of the second pedal 64 and the second pull rope 65, the operator can... The second trolley 66 can be driven to slide in the left and right direction relative to the second slide rail 112 by a simple foot pedal action. The second trolley 66 can hit the second lower connecting rod 62 to make the second lower connecting rod 62 rotate, thereby driving the second upper connecting rod 61 to move from the second support position 611 to the second folding position 612. The operation is simpler, and the design of the second pedal 64 and the second pull rope 65 can quickly respond to the operator's actions, so that the second upper connecting rod 61 can quickly move from the second support position 611 to the second folding position 612, improving the efficiency of loading and unloading operations. The second drive component 6 has a simple structure, low cost, and does not rely on electricity, which reduces the operating cost of the logistics loading and unloading device 100 and enhances the adaptability and durability of the logistics loading and unloading device 100.

[0045] In one embodiment, the first spring balancer 53 is connected to the upright 12 at a higher position than the first spring balancer 53 is connected to the first rotating sleeve 22, and the second spring balancer 63 is connected to the upright 12 at a higher position than the second spring balancer 63 is connected to the second rotating sleeve 32. Specifically, by optimizing the connection positions of the first spring balancer 53 and the second spring balancer 63 to the upright 12, the first spring balancer 53 can always provide an upward force for the first rotating sleeve 22, and the second spring balancer 63 can always provide an upward force for the first rotating sleeve 22. This helps to reduce the force required by the operator when lifting the movable frame 2 or the support frame 3, making the operation easier, improving the lifting efficiency, stability, and operational safety of the logistics loading and unloading device 100, while also increasing the flexibility and durability of the logistics loading and unloading device 100, reducing maintenance costs, and improving operational comfort and user experience.

[0046] In one embodiment, the tension of the first spring balancer 53 is less than the weight of the movable frame 2, and the tension of the second spring balancer 63 is greater than the weight of the support frame 3. Specifically, the tension of the first spring balancer 53 is less than the weight of the movable frame 2, allowing the movable frame 2 to move downward relative to the upright frame 12. The tension of the second spring balancer 63 is greater than the weight of the support frame 3, allowing the second spring balancer 63 to drive the support frame 3 to move upward relative to the upright frame 12, thereby causing the support frame 3 to abut against the movable frame 2. The support frame 3 can stably support the movable frame 2, which can reduce the risk of material falling or device damage due to improper operation and improve the overall operational safety.

[0047] In one embodiment, the first drive assembly 5 further includes a handrail 57, which is connected to the frame body 21. Specifically, since the tension of the first spring balancer 53 is less than the weight of the movable frame 2, the movable frame 2 will move downward relative to the upright frame 12 under its own weight. Therefore, when the logistics loading and unloading device 100 needs to be adjusted to the highest position mode, the operator needs to manually lift the frame body 21, thereby moving the first upper connecting rod 51 from the first folding position 512 to the first support position 511. By setting the handrail 57, a gripping point is provided for the operator, so that the operator can apply force more comfortably when adjusting the position of the movable frame 2, reducing hand fatigue. The design of the handrail 57 takes into account ergonomics, improves the operator's experience when using the device, and also allows the operator to more intuitively perceive the position and movement of the movable frame 2, making it easier to make precise adjustments.

[0048] Please see Figure 5 In one embodiment, the movable frame 2 includes a frame body 21 and a material rack 23. The frame body 21 is slidably engaged with the upright frame 12, and the support frame 3 is located below the frame body 21. The frame body 21 can abut against the support frame 3. The material rack 23 includes a first support rod 231 and a second support rod 232. Both the first support rod 231 and the second support rod 232 are connected to the frame body 21. The first support rod 231 and the second support rod 232 are spaced apart in the horizontal direction. The first support rod 231 and the second support rod 232 are used to support materials. Specifically, the design of the material rack 23 makes loading and unloading operations more convenient. Operators can easily place materials on the first support rod 231 and the second support rod 232, which speeds up the loading and unloading speed. The first support rod 231 and the second support rod 232 are spaced apart in the left and right direction to provide support points for materials. This not only improves the load-bearing capacity of the logistics loading and unloading device 100, but also enhances the stability and safety of the structure. It can adapt to materials of different sizes and shapes, providing greater flexibility, so that the logistics loading and unloading device 100 can be used in a variety of different logistics scenarios.

[0049] In one embodiment, there are multiple first support rods 231, which are spaced apart along the extension direction of the upright 12. The number of second support rods 232 is the same as the number of first support rods 231 and they are arranged in a one-to-one correspondence. Specifically, by setting multiple first support rods 231 and second support rods 232, and making the first support rods 231 and second support rods 232 spaced apart along the extension direction of the upright 12, a one-to-one correspondence is formed. This allows operators to use the logistics loading and unloading device 100 to insert or place multiple materials at once, eliminating the need for manual handling of materials multiple times. This not only improves the load-bearing capacity and loading and unloading efficiency of the logistics loading and unloading device 100, but also improves its adaptability, durability, and space utilization. In this embodiment, there are three first support rods 231 and three second support rods 232, and they are arranged in a one-to-one correspondence. The three first support rods 231 are evenly distributed along the extension direction of the upright frame 12, thereby improving the structural stability of the entire material rack 23. This embodiment does not limit the specific number of first support rods 231 and second support rods 232.
