Description

Technical Field

[0001] This utility model belongs to the field of logistics equipment, and in particular relates to an adjustable cargo loading and unloading platform. Background Technology

[0002] Cargo loading and unloading platforms typically refer to equipment used to assist in loading and unloading goods during logistics, warehousing, and transportation. These platforms primarily aim to improve loading and unloading efficiency, reduce manual labor intensity, and ensure operational safety. Depending on the specific application and technical characteristics, cargo loading and unloading platforms can take on various forms and functions.

[0003] Currently, most common cargo loading and unloading platforms adopt a fixed ramp structure, typically connected to the truck bed at the highest point of the ramp, utilizing the slope to move goods up and down. However, the height of this type of platform is not adjustable, only accommodating truck beds within a specific height range. When faced with vehicles of different bed heights, existing platforms often cannot effectively connect, leading to decreased loading and unloading efficiency. To compensate for this deficiency, it is necessary to build temporary ramps or use auxiliary equipment for transition, increasing operational complexity and manual labor intensity.

[0004] Therefore, there is a particular need for an adjustable loading and unloading platform to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of fixed ramp loading platforms, which have no adjustable height, are difficult to adapt to vehicles with different cargo box heights, reduce loading and unloading efficiency, and increase operational complexity and manual labor intensity, this utility model provides an adjustable loading platform for loading and unloading goods.

[0006] This utility model is achieved through the following technical means: an adjustable loading and unloading platform for goods, including a first hinge plate, a second hinge plate, casters, and an inclined plate. The first hinge plate and the second hinge plate are rotatably connected, together forming a platform for people to stand and move goods. Two casters are rotatably mounted side by side at one end of the second hinge plate, and the inclined plate is rotatably mounted at one end of the second hinge plate. The platform is made of iron, and one side surface of the inclined plate is roughened. It also includes a movable frame, a hydraulic cylinder, a connecting plate, a folding frame, and a top plate. The movable frame is mounted on... Directly below the first hinge plate, the hydraulic cylinder is mounted on the movable frame, with its piston rod extending backward. The connecting plate is fixed to the end of the piston rod of the hydraulic cylinder and forms a sliding fit with the movable frame. The folding frame is set between the movable frame and the connecting plate. The lower side of the folding frame is rotatably connected to the movable frame, and the other lower side is rotatably connected to the connecting plate. The first top plate is set on the upper part of the folding frame, and the upper side of the folding frame is rotatably connected to the first top plate, while the other upper side is slidably connected to the first top plate. The first hinge plate is located above the first top plate, and the two are fixedly connected.

[0007] Preferably, it also includes a mounting plate, an electric cylinder, and a second top plate. The two mounting plates are arranged side by side and fixed to the movable frame. Each mounting plate is equipped with an electric cylinder. The piston rod end of each electric cylinder is fixed to a second top plate. The bottom surface of each second top plate has multiple anti-slip grooves arranged in a straight line.

[0008] Preferably, it also includes baffles, with two symmetrically distributed baffles fixed to the top ends of hinge plate one and hinge plate two respectively.

[0009] Preferably, it also includes a plug rod and a magnet. A plug rod is slidably provided on one side of each of the two baffles on the hinge plate 2. One end of each plug rod passes through the inclined plate and is fixed with a magnet, which is attracted to the inclined plate.

[0010] Preferably, a guide rod is also included, with a guide rod fixed to the top of each top plate 2, and the guide rod passes through the corresponding mounting plate and is slidably connected to it.

[0011] As a preferred option, it also includes an anti-slip mat, with an anti-slip mat laid on both the hinge plate one and the hinge plate two on the working surface where personnel stand.

[0012] Beneficial effects: 1. By setting hinge plate one and hinge plate two with rotational cooperation, the loading platform forms a segmented structure. Then, by utilizing the synergistic effect of the moving frame, hydraulic cylinder, connecting plate, folding frame and top plate one, the height of hinge plate one can be flexibly adjusted according to the different heights of the truck bed, so as to achieve precise docking between the loading platform and the truck bed and improve the adaptability of the loading platform.

[0013] 2. By setting up an installation plate, electric cylinder, and top plate II, and based on the height adjustment of the hinge plate I by hydraulic cylinder, the stability of the loading platform is further enhanced, preventing the platform from shaking or shifting during the loading and unloading process, and ensuring the safe operation of loading and unloading.

[0014] 3. The inclined plate can be quickly fixed and unlocked by the combination of the plug rod and the magnet. When moving the platform, the magnet attracts the inclined plate and fixes it on the second hinge plate to prevent dragging. During loading and unloading operations, the plug rod is pulled lightly to overcome the magnetic attraction and unlock. The inclined plate is rotated to overlap the rear end of the second hinge plate to form a guide ramp, which facilitates the handling of goods. Attached Figure Description

[0020] Example: An adjustable loading platform for loading and unloading goods, such as... Figures 1-4 As shown, the platform includes a hinge plate 1, a hinge plate 2, casters 3, a ramp 14, a baffle 17, and an anti-slip mat 18. The hinge plate 1 and hinge plate 2 are rotatably connected, together forming a platform for personnel to transport goods. Two casters 3 are arranged side-by-side at the rear end of hinge plate 2, facilitating the overall movement of the platform. The ramp 14 is rotatably located at the rear end of hinge plate 2 and is made of iron. The front surface of ramp 14 is roughened; when workers step on ramp 14, this rough surface significantly increases the slip resistance. The friction between the soles of the feet and the inclined plate 14 effectively reduces the risk of workers slipping. Two moving wheels 3 are located below the inclined plate 14. Two symmetrically distributed baffles 17 are fixedly connected to the top of each of the hinge plate 1 and hinge plate 2. The baffles 17 can prevent goods from slipping off the left and right sides of the platform during handling, ensuring the safety of loading and unloading goods and personnel. A layer of anti-slip mat 18 is laid on the working surface of hinge plate 1 and hinge plate 2 for workers to stand on, which can increase the friction between the soles of the shoes and hinge plate 1 and hinge plate 2 when workers are standing. To prevent workers from slipping during cargo handling, the system includes a movable frame 4, a hydraulic cylinder 5, a connecting plate 6, a folding frame 7, and a top plate 9. The movable frame 4 is positioned directly below the hinge plate 1. The hydraulic cylinder 5 is bolted to the movable frame 4, with its piston rod extending rearward. The connecting plate 6 is fixedly connected to the end of the piston rod of the hydraulic cylinder 5 and forms a sliding fit with the movable frame 4, ensuring that the connecting plate 6 can move stably under the action of the piston rod of the hydraulic cylinder 5. The folding frame 7 is positioned between the movable frame 4 and the connecting plate 6, with the lower front side of the folding frame 7 touching the movable frame 4. The lower rear side is rotatably connected to the connecting plate 6. The movement of the connecting plate 6 can be controlled by the extension and retraction of the piston rod of the hydraulic cylinder 5, thereby driving the folding frame 7 to unfold or retract. The top plate 9 is located on the upper part of the folding frame 7, and the upper front side of the folding frame 7 is rotatably connected to the top plate 9, while the upper rear side is slidably connected to the top plate 9. The hinge plate 1 is located above the top plate 9, and the two are fixedly connected. In this way, the unfolding or retraction of the folding frame 7 can drive the top plate 9 and the hinge plate 1 to move up and down, thereby adjusting the height of the hinge plate 1.

[0021] like Figure 1 and Figure 3 As shown, it also includes a mounting plate 10, an electric cylinder 11, a second top plate 12, and a guide rod 13. Two mounting plates 10 are arranged side by side and fixedly connected to the movable frame 4. Each mounting plate 10 is bolted with an electric cylinder 11. The piston rod of each electric cylinder 11 is fixedly connected to a second top plate 12. The extension and retraction of the piston rod of the electric cylinder 11 can control the up and down movement of the second top plate 12. The bottom surface of each second top plate 12 has multiple anti-slip grooves arranged in a straight line. The anti-slip grooves can increase the friction between the second top plate 12 and the ground when it contacts the ground. A guide rod 13 is fixedly connected to the top of each second top plate 12. The guide rod 13 passes through the corresponding mounting plate 10 and slides with it. The guide rod 13 provides guidance for the movement of the second top plate 12, ensuring that the second top plate 12 moves up and down smoothly under the action of the electric cylinder 11.

[0022] like Figure 1 and Figure 4 As shown, it also includes a rod 15 and a magnet 16. A rod 15 is slidably disposed on the rear side of each of the two baffles 17 on the hinge plate 2. The rear end of each rod 15 passes through the inclined plate 14 and is fixedly connected to a magnet 16. The magnet 16 is attracted to the inclined plate 14. Through this attraction, the inclined plate 14 is fixed to the hinge plate 2. When it is necessary to adjust the angle of the inclined plate 14, it is only necessary to overcome the attraction force of the magnet 16, which makes the operation convenient and quick.

[0023] In the initial state, the bottom surface of the top plate 212 is higher than the bottom surface of the mobile frame 4. At this time, the mobile frame 4 is in direct contact with the ground and can be moved at will, making it convenient to move the platform to the truck that needs to load and unload goods.

[0024] When the loading platform is needed, the staff first moves the platform closer to the truck bed. During the movement, they closely observe and ensure that the articulated plate 1 is aligned with the truck bed. Once aligned, the staff activates the hydraulic cylinder 5 according to the actual height of the truck bed, controlling its piston rod to retract and move the connecting plate 6 forward. The movement of the connecting plate 6 causes the folding frame 7 to unfold. The unfolding of the folding frame 7 causes the top plate 9 and the articulated plate 1 to move upward, adjusting the height of the articulated plate 1. During this process, the articulated plate 2 will rotate accordingly. At the same time, the moving wheel 3 will roll in contact with the ground to prevent the articulated plate 2 from scraping the ground during the adjustment process and avoid damaging the articulated plate 2 due to friction. Once the articulated plate 1 is adjusted to the appropriate height and connected with the truck bed, the staff closes the hydraulic cylinder 5 to keep the height of the articulated plate 1 stable.

[0025] Next, start the electric cylinder 11 to control its piston rod to extend and drive the top plate 12 to move downward. As the top plate 12 descends, when it moves to the appropriate position and touches the ground, the moving frame 4 will be suspended in the air due to the loss of ground support. At this time, immediately close the electric cylinder 11 to fix the position of the top plate 12. The fixing of the top plate 12 plays the role of stabilizing the moving frame 4, thereby ensuring that the articulated plate 1 can stably connect with the truck bed, preventing the loading platform from shaking or shifting during the loading and unloading of goods, and ensuring the safe and efficient loading and unloading of goods.

[0026] Finally, pull the plug rod 15 forward to disengage the magnet 16 from the inclined plate 14. After the magnet 16 disengages, the inclined plate 14 loses its fixation. Then, rotate the inclined plate 14 clockwise downward to a suitable angle so that the end of the inclined plate 14 not connected to the hinge plate 2 contacts the ground and is held in place by the ground. This forms a slope with a suitable gradient at the rear end of the hinge plate 2, which facilitates the handling of goods between the platform and the ground, improving the convenience of loading and unloading goods.
