Description

Technical Field

[0001] This utility model relates to the technical field of cargo loading and unloading platforms, specifically a cargo loading and unloading support platform. Background Technology

[0002] During the loading and unloading process, the core function of the support platform is to eliminate the height difference between the loading and unloading body and the work site. The goods loaded in the container are first placed on the top side of the flatbed truck, and then loaded into the truck. There is a natural height difference between the truck floor and the ground, which makes it inconvenient to load and unload directly. Therefore, a support platform is needed.

[0003] A Chinese patent with authorization announcement number CN120156930A discloses a cargo loading and unloading platform structure, including a base with an internal cavity. A drive assembly for rotating a first rotating rod is fixedly installed inside the cavity, and a battery is fixedly installed on the top of the base. This cargo loading and unloading platform structure allows the drive wheel to rotate via the internal drive assembly, eliminating the need for manual pulling when moving the device. A lifting assembly on the base allows for adjustment of the platform height, facilitating loading and unloading of goods. A rotating assembly on the lifting bracket allows the platform to be tilted, making unloading easier for workers.

[0004] However, the above structure still has some problems. In practical applications, the support platform cannot be extended or retracted, resulting in a large space occupation when not in use, which reduces the site utilization rate. It also cannot adapt to flatbed trucks of different lengths. When the flatbed truck is long, the support platform is not long enough, and the goods may exceed the edge of the support platform, resulting in an unstable center of gravity and an increased risk of goods slipping. Therefore, a cargo loading and unloading support platform is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a cargo loading and unloading support platform.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A cargo loading and unloading support platform of this utility model includes a base. Two sliding plates are symmetrically installed above the base. A support platform is installed on one side of each sliding plate. An upward-opening groove is formed inside one end of the support platform. An expansion plate is slidably installed inside the groove. The top side of the expansion plate is horizontally aligned with the top side of the support platform. A cylinder is installed on the bottom side of the middle section of the support platform. An actuating rod is installed at the working end of the cylinder. An mounting plate is installed on one side of the actuating rod. The mounting plate is fixedly installed on the bottom side of one end of the expansion plate. Two threaded rods are symmetrically and rotatably installed at both ends. Each threaded rod has a limit handle at its top and a gripping plate at its bottom. A cylinder drives the rod to move the mounting plate, which in turn causes the expansion plate to slide within the slide groove. This allows for the extension and retraction adjustment of the support platform's surface. When not in use, the expansion plate can be retracted into the slide groove, reducing space occupation and facilitating storage. At the same time, the platform's surface length can be flexibly adjusted according to the length of cargo flatbeds, ensuring that the flatbed can be stably placed on the support platform. Furthermore, by rotating the threaded rods, the gripping plate makes contact, allowing the extended expansion plate to be supported, improving the stability during cargo loading and unloading.

[0007] Preferably, two fixed frames are symmetrically installed on the top side of the base. Each fixed frame is equipped with a drive motor on its top side, and a lead screw is installed at the output end of the drive motor. Each fixed frame has a slide rail inside, and a sliding plate is slidably installed inside the slide rail. A screw hole is opened through the inside of the sliding plate, and one end of the lead screw passes through the screw hole and is rotatably installed inside the bottom side of the slide rail. The drive motor drives the lead screw to rotate, and the sliding plate slides up and down in the slide rail, thereby adjusting the position and height of the support platform. This allows for precise adjustment of the distance between the support platform and the truck according to the height difference between the truck floor and the ground, enabling goods to be loaded and unloaded smoothly and stably between the flatbed truck and the truck. This avoids loading and unloading difficulties caused by height mismatch and improves the efficiency of loading and unloading operations.

[0008] Preferably, two fixing plates are installed on both sides of the other end of the support platform. A servo motor is installed on one side of one of the fixing plates, and a bidirectional screw is installed at the output end of the servo motor. Two rectangular slots are symmetrically opened inside the other end of the support platform. Movable blocks are slidably installed inside each rectangular slot. Threaded holes are opened at the bottom ends of each movable block. One end of the bidirectional screw passes through the threaded hole and is rotatably installed inside the other fixing plate. A fixed clamping plate is installed on the top side of the movable block. When the cargo flatbed is pushed to the top side of the support platform, the fixed clamping plate is moved towards the center by controlling the servo motor to limit one end of the cargo. This effectively prevents the flatbed from detaching from the support platform due to inertia, ensures the stability of the cargo during loading and unloading, prevents the cargo from slipping and being damaged, ensures the smooth progress of loading and unloading operations, and improves the efficiency of cargo loading and unloading.

[0009] Preferably, the fixing clamp is L-shaped, and the inner wall of the fixing clamp is equipped with silicone pads. The L-shape of the fixing clamp can better fit the end of the goods, providing a more stable limiting effect. The silicone pads installed on the inner wall of the fixing clamp can play a buffering role during the limiting process, avoiding direct contact between the fixing clamp and the goods and causing wear on the surface of the goods, effectively protecting the goods and reducing the damage rate of the goods during loading and unloading.

[0010] Preferably, the base is equipped with casters at all four corners of its bottom side, allowing workers to easily move the support platform to a suitable position according to the actual needs of the loading and unloading site.

[0011] Preferably, a vertical plate is installed at the top edge of the support platform, and a control panel is installed on one side of the vertical plate. The control panel is electrically connected to the electrical components inside the device and is used to operate and control the electrical components inside the device. The control panel is electrically connected to the electrical components inside the device, and the operator can centrally operate and control the various electrical components inside the device through the control panel.

[0012] The advantages of this utility model are: 1. This utility model starts the cylinder through the control panel. The cylinder pushes the rod and the mounting plate to drive the expansion plate to slide in the slide groove. The length of the support platform is adjusted to match the flatbed truck. After it is in place, the cylinder stops extending. Rotating the limit handle causes the threaded rod to drive the gripping plate to touch the ground and compact the support. After the operation is completed, the threaded rod is rotated to lift the gripping plate off the ground, the cylinder is shortened, and the expansion plate retracts into the slide groove, reducing space for easy storage. 2. This utility model starts a servo motor, whose output drives a bidirectional screw to rotate, causing two movable blocks to move synchronously towards the center along a rectangular groove. The L-shaped fixed clamp moves with the movable blocks until the inner wall of the fixed clamp clamps the goods, achieving a limit position. This effectively prevents the flatbed cart from detaching from the support platform due to inertia, ensuring the stability of the goods during loading and unloading, preventing the goods from slipping and getting damaged, ensuring the smooth progress of loading and unloading operations, and improving the efficiency of loading and unloading. The silicone soft pad buffers the impact force during clamping, preventing wear and tear on the goods. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] Please see Figure 1-3 As shown, a cargo loading and unloading support platform includes a base 1. Two sliding plates 2 are symmetrically installed on the top of the base 1. A support platform 201 is installed on one side of each sliding plate 2. An upward-opening groove 202 is opened inside one end of the support platform 201. An expansion plate 203 is slidably installed inside the groove 202. The top side of the expansion plate 203 is on the same horizontal line as the top side of the support platform 201. A cylinder 204 is installed on the bottom side of the middle end of the support platform 201. An actuating rod 205 is installed on the working end of the cylinder 204. An mounting plate 206 is installed on one side of the actuating rod 205. The mounting plate 206 is fixedly installed on the bottom side of one end of the expansion plate 203. Two threaded rods 207 are symmetrically and rotatably installed through one end of the expansion plate 203. A limit handle 208 is installed at the top of each threaded rod 207. A gripping plate 209 is installed at the bottom of each threaded rod 207. A vertical plate 6 is installed at the top edge of the support platform 201, and a control panel 601 is installed on one side of the vertical plate 6. The control panel 601 is electrically connected to the electrical components inside the device and is used to control the operation of the electrical components inside the device. In practical applications, the support platform 201 cannot be extended or retracted during operation, resulting in a large space occupation when not in use, reducing site utilization. It also cannot accommodate flatbed trucks of different lengths. When the flatbed truck is long, the support platform 201 is insufficient in length, and the goods may extend beyond the edge of the support platform 201, leading to instability and an increased risk of goods slipping. Depending on the length of the flatbed truck, the operator controls the cylinder 204 to start via the control panel 601. The actuating end of the cylinder 204 pushes the actuating rod 205 to extend. The actuating rod 205, through the mounting plate 206 on one side, drives the expansion plate 203 in the sliding groove. In step 202, the top side of the expansion plate 203 slides horizontally with the top side of the support platform 201, ensuring a flat platform. The length of the support platform 201 can be flexibly adjusted according to the length of the flatbed truck, ensuring that the flatbed truck can be stably placed on the support platform 201. When the expansion plate 203 extends to the position suitable for the length of the flatbed truck, the working end of the cylinder 204 stops extending. The operator rotates the two limit handles 208 at one end of the expansion plate 203, driving the threaded rod 207 to rotate downward until the gripping plate 209 at the bottom of the threaded rod 207 contacts and compacts the ground, forming a stable support for the extended expansion plate 203. After the support platform operation is completed, the gripping plate 209 is moved away from the ground by rotating the threaded rod 207, and at the same time, the working end of the cylinder 204 is shortened, causing the expansion plate 203 to retract into the interior of the slide groove 202, reducing the space occupied and facilitating storage.

[0018] Please see Figure 1 , 2As shown in Figures 4 and 5, two fixed frames 3 are symmetrically installed on the top side of the base 1. A drive motor 301 is installed on the top side of each fixed frame 3. A lead screw 302 is installed at the output end of the drive motor 301. A slide rail 303 is provided inside each fixed frame 3. The sliding plate 2 is slidably installed inside the slide rail 303. A screw hole is provided through the inside of the sliding plate 2. One end of the lead screw 302 passes through the screw hole and is rotatably installed inside the bottom side of the slide rail 303. The other end of the support platform 201 is equipped with two fixing plates 4 on both sides. A servo motor 401 is installed on one side of one of the fixing plates 4. A bidirectional screw 402 is installed at the output end of the servo motor 401. Two rectangular slots 403 are symmetrically opened inside the other end of the support platform 201. Movable blocks 404 are slidably installed inside each of the rectangular slots 403. Threaded holes are opened at the bottom of each movable block 404. One end of the bidirectional screw 402 passes through the threaded hole and is rotatably installed inside the other fixing plate 4. A fixing clamp 405 is installed on the top side of the movable block 404. The fixing plate 405 is L-shaped, and the inner wall of the fixing plate 405 is equipped with silicone pads. The base 1 is equipped with four casters 5 at its bottom corners. During operation, the core function of the support platform is to eliminate the height difference between the loading / unloading body and the work area. Goods loaded in the container are first placed on the top of the flatbed truck, then loaded into the truck. The truck floor has a natural height difference from the ground, making direct loading and unloading inconvenient. Therefore, a support platform is needed. The casters 5 are used to move the support platform to the truck's position. When the support platform 201 is level with the ground, the worker pushes the flatbed truck loaded with goods onto the support platform 201, positioning one end close to the side of the support platform 201 where the fixing plate 4 is installed. The servo motor 401 is started via the control panel 601. The output end of the servo motor 401 drives the bidirectional screw 402 to rotate, causing the two movable blocks 404 to move synchronously towards the center along the rectangular groove 403. The L-shaped fixed clamp 405 moves with the movable blocks 404 until the inner wall of the fixed clamp 405 clamps the goods, achieving the limit and effectively preventing the flatbed cart from detaching from the support platform 201 due to inertia. This ensures the stability of the goods during loading and unloading, prevents the goods from slipping and being damaged, ensures the smooth progress of loading and unloading operations, and improves the efficiency of loading and unloading. The silicone soft pad buffers the impact force during clamping and avoids wear on the goods. The specific model of the movable wheel 5 is LK-PO160K-FI. Subsequently, the operator simultaneously starts the drive motor 301 through the control panel 601. The output end of the drive motor 301 drives the lead screw 302 to rotate. Since the screw hole inside the sliding plate 2 is threadedly engaged with the lead screw 302, the rotational motion of the lead screw 302 is converted into the linear motion of the sliding plate 2 along the slide rail 303. The two sliding plates 2 slide up and down synchronously, driving the support platform 201 connected to their top to rise and fall until the height of the support platform 201 is level with the height of the truck bed. After the operation is completed, the components are operated in reverse through the control panel 601. The servo motor 401 reverses to reset the fixed clamp 405, the cylinder 204 retracts to drive the expansion plate 203 to retract into the slide 202, the drive motor 301 reverses to lower the support platform 201 to the lowest position, and finally the brakes of the moving wheel 5 are unlocked to move the platform to the storage position.

[0019] Working principle: Based on the length of the cargo flatbed, the operator controls the cylinder 204 to start via the control panel 601. The actuating end of the cylinder 204 pushes the actuating rod 205 to extend. The actuating rod 205 drives the expansion plate 203 to slide in the slide groove 202 via the mounting plate 206 on one side. The top side of the expansion plate 203 remains horizontal with the top side of the support platform 201, ensuring a flat platform. The length of the support platform 201 can be flexibly adjusted according to cargo flatbeds of different lengths, ensuring that the flatbed can be stably placed on the support platform 201. When the expansion plate 203 extends to the appropriate flat surface... After the platform reaches the desired length, the extension end of cylinder 204 stops extending. The operator rotates the two limit handles 208 at one end of the expansion plate 203, causing the threaded rod 207 to rotate downwards until the gripping plate 209 at the bottom of the threaded rod 207 contacts and compacts the ground, providing stable support for the extended expansion plate 203. After the platform operation is completed, the gripping plate 209 is moved away from the ground by rotating the threaded rod 207, while the extension end of cylinder 204 is shortened, causing the expansion plate 203 to retract into the interior of the chute 202, reducing space occupation and facilitating storage. With the help of the movable wheels 5, the support platform is moved to the position of the truck. When the support platform 201 is at the same level as the ground, the staff pushes the flatbed truck loaded with goods onto the support platform 201, so that one end of it is close to the side of the support platform 201 where the fixing plate 4 is installed. The servo motor 401 is started through the control panel 601. The output end of the servo motor 401 drives the bidirectional screw 402 to rotate, so that the two movable blocks 404 move synchronously towards the middle along the rectangular groove 403. The L-shaped fixing plate 405 moves with the movable blocks 404 until the inner wall of the fixing plate 405 clamps the goods, realizing the limit and effectively preventing the flatbed truck from falling off the support platform 201 due to inertia. This ensures the stability of the goods during loading and unloading, prevents the goods from slipping and being damaged, ensures the smooth progress of loading and unloading operations, and improves the efficiency of loading and unloading. The silicone soft pad buffers the impact force during clamping and avoids wear on the goods. The specific model of the movable wheel 5 is LK-PO160K-FI.
