AI Technical Summary
During use, existing loading and unloading lifting platforms suffer from narrow visibility within the truck bed, causing the control delivery platform to collide with and damage the truck bed. Furthermore, the heavy weight of the cargo during unloading can cause the truck's center of gravity to shift and the truck to overturn.
The motor-driven transmission gear rod drives the transport plate to slide slowly on the guide rail. Combined with the design of limit posts and damping support rods, it ensures that the transport plate slowly tilts into the carriage with the rollers as the support point, and the elastic buffer rod reduces the center of gravity shift.
This effectively avoids the problems of delivery pallets hitting the truck bed and causing damage, as well as truck overturning, thus improving the safety and efficiency of loading and unloading.

Description
A loading and unloading lifting platform Technical Field
[0001] This utility model relates to the field of lifting platform technology, specifically to a loading and unloading lifting platform. Background Technology
[0002] In logistics transportation, it is often necessary to load goods from the ground onto trucks or unload them from trucks onto the ground. Currently, the most common methods are using forklifts or cranes. However, these methods require that forklifts and cranes be readily available at all times. When these conditions are not met, goods can only be handled by hand or dragged between the truck and the ground using a flatbed support. This is time-consuming, labor-intensive, and poses safety risks. Moreover, the goods are easily damaged by collisions and tipping, resulting in a very unsatisfactory handling effect.
[0003] The existing technology has the following problems:
[0004] 1. During the use of existing loading and unloading lifting platforms, the narrow field of vision inside the truck bed when manually operating the lifting platform to enter the truck bed to unload goods makes it easy for the operator to cause the delivery platform to collide with the truck bed, resulting in damage to the truck bed.
[0005] 2. During the use of existing loading and unloading lifting platforms, the large weight of the goods during unloading can cause the center of gravity of the truck to shift, resulting in the truck tipping over. Summary of the Invention
[0006] This utility model provides a loading and unloading lifting platform to solve the problems mentioned in the background art.
[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0008] A loading and unloading lifting platform includes a platform, the top of which has a groove, and a lifting platform is fixedly connected to the bottom of the inner wall of the groove. The output end of the lifting platform is fixedly connected to a loading and unloading platform, and guide components are provided at both ends of the top of the loading and unloading platform.
[0009] A further improvement of the present invention is that the guiding component includes limiting plates fixedly connected to both ends of the top of the loading and unloading platform, and a guiding rail is fixedly connected to the top of the limiting plate. A limiting post is slidably connected to the inner wall of the guiding rail, and a conveying plate is fixedly connected to the middle of the outer wall of the limiting post. A toothed plate is fixedly connected to the center of the bottom of the conveying plate.
[0010] A further improvement of the present invention is that: an extension platform is fixedly connected to one end of the top center of the loading and unloading platform, and a motor is fixedly connected to one end of the top of the extension platform. A transmission gear rod is fixedly connected to the output end of the motor, and the side of the outer wall of the transmission gear rod away from the motor is rotatably connected to one end of the top of the extension platform, while the top of the transmission gear rod meshes with the bottom of the toothed plate.
[0011] A further improvement of this utility model is that: the two ends of the bottom of the conveying plate away from the toothed plate are fixedly connected to limit boxes, and the inner wall of the limit boxes is rotatably connected to a damping support rod.
[0012] A further improvement of this utility model is that a guide box is fixedly connected to the middle of one side of the outer wall of the limiting plate, and the inner wall of the guide box is slidably connected to one end of the outer wall of the damping support rod.
[0013] A further improvement of the present invention is that: a buffer frame is fixedly connected to the top of the loading and unloading platform between the limiting plate and the extension platform, and an elastic buffer rod is slidably connected to the inner wall of the buffer frame, and the top of the elastic buffer rod overlaps with the outer wall of the damping support rod.
[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0015] 1. This utility model provides a loading and unloading lifting platform. A motor drives a transmission gear rod to rotate, causing the conveying plate to slide slowly on the arc surface of the guide rail, supported by a limiting post. Simultaneously, the lifting platform slowly rises, causing the conveying plate to tilt slowly, supported by rollers and the bottom of the cargo box. This allows goods placed on the conveying plate to slowly slide into the truck bed under the influence of the tilt angle. This further solves the problem of traditional loading and unloading lifting platforms where, during manual operation, the narrow field of vision inside the truck bed makes it easy for operators to accidentally cause the delivery plate to collide with the truck bed, resulting in damage.
[0016] 2. This utility model provides a loading and unloading lifting platform. When the conveying plate is tilted at an angle by the toothed plate, one side of the outer wall of the damping support rod presses against the elastic buffer rod set on the inner wall of the buffer frame. This buffers the damping support rod and reduces the vibration caused by the shift of the center of gravity of the conveying plate. It avoids the problem of the conveying plate shaking when the weight of the goods is continuously transferred into the cargo box during unloading. It further solves the problem of the truck tipping over when the center of gravity of the truck shifts due to the large weight of the goods during unloading in traditional loading and unloading lifting platforms.

[0024] The present invention will be further described in detail below with reference to embodiments:
[0025] As shown in Figures 1-6, this utility model provides a loading and unloading lifting platform, including a platform 1. The top of the platform 1 has a groove 2, and a lifting platform 3 is fixedly connected to the bottom of the inner wall of the groove 2. The output end of the lifting platform 3 is fixedly connected to a loading and unloading platform 4, and the top two ends of the loading and unloading platform 4 are provided with guide components. The guide components include limiting plates 5 fixedly connected to the top two ends of the loading and unloading platform 4, and a guide rail 6 fixedly connected to the top of the limiting plates 5. The inner wall of the guide rail 6 is slidably connected to a limiting post 7, and a conveying plate 8 is fixedly connected to the middle of the outer wall of the limiting post 7. A toothed plate 9 is fixedly connected to the center of the bottom of the conveying plate 8. An extension platform 10 is fixedly connected to one end of the center of the top of the loading and unloading platform 4, and a motor 11 is fixedly connected to one end of the top of the extension platform 10. The output end of the motor 11 is fixedly connected to a transmission gear rod 12, and the side of the outer wall of the transmission gear rod 12 away from the motor 11 is rotatably connected to one end of the top of the extension platform 10. The top of the transmission gear rod 12 meshes with the bottom of the toothed plate 9.
[0026] During operation, a groove 2 is set on the top of the platform 1, and the lifting platform 3 is placed in the groove 2. When the truck drives to one side of the platform 1, a loading and unloading platform 4 is set at the output end of the lifting platform 3, and limit plates 5 are set at both ends of the top of the loading and unloading platform 4. The guide rail 6 set on the top of the limit plate 5 supports the transport plate 8. The forklift is used to place the goods on the surface of the transport plate 8, and the forklift is moved away from the transport plate 8. The lifting platform 3 is started, which pushes the loading and unloading platform 4 set at the output end, and moves the transport plate with the goods placed on it. 8. Move upwards until the rollers at one end of the outer wall of the conveying plate 8 are higher than the bottom of the inner wall of the cargo box. At this time, an extension platform 10 is set at one end of the top center of the loading and unloading platform 4, and a motor 11 is set at one end of the top of the extension platform 10. The motor 11 is started to drive the transmission gear rod 12 set at its output end, so that the transmission gear rod 12 drives the toothed plate 9 set at the bottom center of the conveying plate 8. Thus, the conveying plate 8 moves towards the inside of the cargo box under the limit of the guide rail 6, and at the same time, the rollers at one end of the outer wall of the conveying plate 8 contact the bottom surface of the cargo box. The bottom of the inner wall of the container moves slowly. Because one end of the guide rail 6 is curved, and the limiting posts 7 set at both ends of the outer wall of the conveying plate 8 are on the curved surface of the guide rail 6, the two sides of the outer wall of the conveying plate 8 are separated from the guide rail 6. At this time, the motor 11 drives the transmission gear rod 12 to rotate again, and the conveying plate 8 slides slowly on the curved surface of the guide rail 6 with the limiting posts 7 as the support point. With the lifting platform 3 rising slowly, the conveying plate 8 tilts slowly with the rollers and the bottom surface of the cargo box as the support point. The goods placed on the surface of the conveying plate 8 slide slowly into the truck bed under the influence of the tilt angle of the conveying plate 8. At this time, the driver starts the truck and moves forward, and the goods piled on the surface of the conveying plate 8 and the corner of the cargo box slide off the surface of the conveying plate 8 under the influence of inertia and pile up in the cargo box, thus completing the loading of the cargo box. This further solves the problem that when using traditional loading and unloading lifting platforms, the narrow field of vision in the cargo box when manually operating the lifting platform to enter the cargo box to unload goods makes it easy for the operator to operate the delivery plate to crash into the cargo box, thus causing damage to the cargo box.
[0027] The bottom ends of the conveying plate 8 away from the toothed plate 9 are fixedly connected to the limiting boxes 13, and the inner wall of the limiting boxes 13 is rotatably connected to the damping support rod 14. The middle part of one side of the outer wall of the limiting plate 5 is fixedly connected to the guide box 15, and the inner wall of the guide box 15 is slidably connected to one end of the outer wall of the damping support rod 14. The top of the loading and unloading platform 4 is fixedly connected to the buffer frame 16 between the limiting plate 5 and the extension platform 10, and the inner wall of the buffer frame 16 is slidably connected to the elastic buffer rod 17, and the top of the elastic buffer rod 17 overlaps with the outer wall of the damping support rod 14.
[0028] During operation, limiting boxes 13 are installed at both ends of the bottom of the conveyor plate 8 away from the toothed plate 9. Damping support rods 14 are installed on the inner walls of the limiting boxes 13 for limiting. A guide box 15 is installed in the middle of one side of the outer wall of the limiting plate 5 to guide one end of the damping support rod 14. The cooperation between the limiting boxes 13 and the guide box 15 prevents the damping support rod 14 from shifting when the conveyor plate 8 moves. A buffer frame 16 is installed at the top of the loading / unloading platform 4 between the limiting plate 5 and the extension platform 10, with elastic buffer rods 17 installed on the inner wall of the buffer frame 16. When unloading goods, the conveyor plate 8 moves the damping support rod 14 to the end of the guide box 15, forming a triangular structure between the conveyor plate 8 and the loading / unloading platform 4 using the damping support rod 14, thereby achieving... The conveyor plate 8 is reinforced to prevent it from tilting when the conveyor reaches its surface. When loading and unloading goods, the conveyor plate 8 uses the limit post 7 as a support point and the motor 11 drives the transmission gear rod 12. Through the toothed plate 9, the conveyor plate 8 tilts at an angle, causing one side of the outer wall of the damping support rod 14 to press against the elastic buffer rod 17 on the inner wall of the buffer frame 16. This buffers the damping support rod 14 and reduces the vibration caused by the shift of the center of gravity of the conveyor plate 8. It also prevents the conveyor plate 8 from shaking when the weight of the goods is continuously transferred into the cargo box during unloading. This further solves the problem of truck overturning caused by the shift of the center of gravity of the truck when the heavy weight of the goods is unloaded during the use of traditional loading and unloading lifting platforms.
[0029] The working principle of this loading and unloading lifting platform will be explained in detail below.
[0030] As shown in Figures 1-6, a groove 2 is set on the top of the platform 1, and the lifting platform 3 is placed in the groove 2. When the truck drives to one side of the platform 1, a loading and unloading platform 4 is set at the output end of the lifting platform 3, and limit plates 5 are set at both ends of the top of the loading and unloading platform 4. The guide rail 6 set on the top of the limit plate 5 supports the transport plate 8. The forklift is used to place the goods on the surface of the transport plate 8 and move the forklift away from the transport plate 8. The lifting platform 3 is started, which pushes the loading and unloading platform 4 set at the output end and drives the transport plate 8 with the goods on its top to move upward until the roller set on one end of the outer wall of the transport plate 8 is higher than the bottom of the inner wall of the cargo box. At this time, the loading and unloading is completed. An extension platform 10 is installed at one end of the top center of platform 4, and a motor 11 is installed at one end of the top of the extension platform 10. Starting the motor 11 drives the transmission gear rod 12 at its output end, which in turn drives the toothed plate 9 at the bottom center of the conveyor plate 8. This causes the conveyor plate 8 to move towards the interior of the cargo box under the constraint of the guide rail 6. Simultaneously, the rollers at one end of the outer wall of the conveyor plate 8 contact the bottom surface of the cargo box, moving slowly along the bottom of the inner wall of the cargo box. Because one end of the guide rail 6 is curved, and the limiting posts 7 at both ends of the outer wall of the conveyor plate 8 are located on the curved surface of the guide rail 6, the two sides of the outer wall of the conveyor plate 8 disengage from the guide rail 6. At this point, electricity... The motor 11 drives the transmission gear rod 12 to rotate again, causing the conveying plate 8 to slide slowly on the arc surface of the guide rail 6 with the limit post 7 as the support point. Simultaneously, the lifting platform 3 slowly rises, causing the conveying plate 8 to rotate slowly with the rollers and the bottom of the cargo box as support points. This allows the goods placed on the surface of the conveying plate 8 to slowly slide into the truck bed due to the tilt angle of the conveying plate 8. At this time, the driver starts the truck and moves it forward, causing the goods piled on the surface of the conveying plate 8 and the corner of the cargo box to slide off the surface of the conveying plate 8 under the influence of inertia and accumulate in the cargo box, thus completing the loading of the cargo box. When it is necessary to unload the cargo from the truck, the motor 11 extends the conveying plate 8. The platform forms a contact point with the ground of the cargo box, facilitating the transfer of the conveyor to the surface of the conveyor plate 8. The damping support rod 14 and the buffer frame 16 work together to support the conveyor plate 8, allowing workers to place the unloaded goods into the conveyor and then use the conveyor belt to transport and discharge them. This avoids the problem of trucks tipping over due to the large weight of the goods during unloading, which can cause the truck's center of gravity to shift. Furthermore, it solves the problem of traditional loading and unloading lifting platforms where, during manual operation, the narrow field of vision inside the truck bed makes it easy for operators to accidentally push the delivery plate into the truck bed, causing damage.
[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
