[0002] Import and export of goods is an economic activity involving the trade of goods with other countries or regions. The main objects of import and export of goods include food, live animals, beverages, and mineral fuels. In the course of various commodity transactions, some large-sized goods inevitably come into play, requiring staff to use specialized equipment for transfer and loading.

[0003] An existing patent (publication number: CN221835390U) discloses a large cargo transfer device for import and export, including a mobile base. A battery is fixedly installed at the bottom center of the mobile base, and a positioning and feeding assembly is fixedly installed at the top of the mobile base. The positioning and feeding assembly includes a forward and reverse motor, a threaded column, a slide, and a connecting rope. The middle of one side of the mobile base is fixedly connected to the outside of the forward and reverse motor. In the process of implementing this solution, the inventors discovered the following problems in the existing technology that have not been adequately addressed: 1. While a clamping device is used at the front end of the cargo for auxiliary loading, once the cargo is on the mobile base, the single front clamping device makes it easy for heavy cargo to slip. Furthermore, the unidirectional clamping requires tightening the cargo, which can easily lead to excessive force and damage. Utility Model Content

[0016] Please see Figures 1 to 10 This utility model provides a technical solution: a large cargo transfer device for import and export of goods, including a vehicle body 1, a guardrail 2 fixedly connected to the top of the vehicle body 1, a pull rod 3 fixedly connected to the front end of the vehicle body 1, a loading plate 4 rotatably connected to the rear end of the vehicle body 1, and a clamping mechanism 5 for clamping goods is provided inside the vehicle body 1.

[0017] In this embodiment, as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the clamping mechanism 5 includes an installation compartment 51 opened inside the vehicle body 1. Two threaded rods 52 are symmetrically rotatably connected in the inner wall of the installation compartment 51, and the two threaded rods 52 are connected by a transmission belt. Protrusions 53 are provided in the threaded grooves of the two threaded rods 52. Control sleeves 515 are fixedly connected to the bottom ends of the two protrusions 53, and the same push plate 54 is fixedly connected to the top ends of the two control sleeves 515. A clamping platform 55 is threadedly connected to the outer wall of the threaded rod 52. The clamping platform 55 is equipped with a replaceable clamping component 56. With the push plate 54, the goods can be pushed from the rear end, reducing the load pressure on the front clamping platform 55 and preventing slippage and damage to the goods.

[0018] In this embodiment, as Figure 5 and Figure 6 As shown, the control sleeve 515 has a through groove 57 inside, and the threaded rod 52 passes through the control sleeve 515 through the through groove 57. The control sleeve 515 is connected to the threaded rod 52 by the protrusion 53. The through groove 57 allows the control sleeve 515 to be undriven during the loading process, so that the push plate 54 can automatically pop out and fit against the rear end of the goods, which facilitates the pushing of goods.

[0019] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a control groove for accommodating the push plate 54 is provided on the outer wall of the vehicle body 1. Sliding grooves 58 for sliding the control sleeve 515 and the clamping platform 55 are symmetrically provided on both sides of the top of the vehicle body 1. The sliding grooves 58 and the control groove are connected. Through the setting of the control groove and the sliding groove 58, the control sleeve 515 and the clamping platform 55 can be stably driven to move horizontally.

[0020] In this embodiment, as Figure 5 , Figure 6 and Figure 7As shown, the clamping mechanism 5 also includes a positioning post 59 slidably disposed on the bottom wall of the mounting chamber 51. A W-shaped groove 510 is provided on the outer wall of the positioning post 59, and a V-shaped groove 511 is connected to the top of the W-shaped groove 510. The groove walls of the W-shaped groove 510 and the V-shaped groove 511 are staggered. Wedge blocks 512 are fixedly connected to both ends of the groove wall of the W-shaped groove 510. A spring telescopic rod 513 is slidably connected in the W-shaped groove 510, and the spring telescopic rod 513 slides on the control sleeve 515. Spring rods 514 are fixedly connected to both ends of the side wall of the spring telescopic rod 513, and both spring rods 514 are fixedly connected to the inner wall of the control sleeve 515. The inclined surface of the wedge block 512 in the left end wall of the W-shaped groove 510 faces the V-shaped groove 511, and the inclined surface of the wedge block 512 in the right end wall of the W-shaped groove 510 faces the W-shaped groove 510. A return spring is fixedly connected to the inner wall of the positioning post 59, and the top end of the return spring is fixedly connected to the inner wall of the control sleeve 515. The positioning post 59 is inserted into the inner wall of the control sleeve 515. By setting two spring rods 514 on the outer wall of the spring telescopic rod 513, the spring telescopic rod 513 can slide left and right when it moves back and forth in the V-groove 511 and the W-groove 510, thus avoiding motion interference.

[0021] In this embodiment, as Figure 3 , Figure 4 , Figure 8 , Figure 9 and Figure 10 As shown, the clamping member 56 includes a hydraulic telescopic rod assembly 561 fixed inside the clamping platform 55. A connecting rod 562 is fixedly connected to the front end of the hydraulic telescopic rod assembly 561, and a moving plate 563 is fixedly connected to the front end of the connecting rod 562. A lever 564 is slidably connected to the inner wall of the moving plate 563, and the lever 564 and the inner wall of the moving plate 563 are connected by a spring. A lever sleeve 565 is fixedly connected to the front end of the lever 564. An installation post 566 is inserted into the inner wall of the actuating sleeve 565, and a half clamping block 567 is fixedly connected to the front end of the installation post 566. A limiting groove 568 is opened on the outer wall of the installation post 566. A limiting plate 569 is fitted and connected to the inner wall of the limiting groove 568, and the top end of the limiting plate 569 is rotatably connected to the inner wall of the moving plate 563. A limiting protrusion 5610 is fitted and connected to the rear end of the limiting plate 569, and the limiting protrusion 5610 is fixedly connected to the inner wall of the moving plate 563. The replaceable half clamping block 567 facilitates the maintenance of the equipment by the staff, and the staff can quickly change the clamps.

[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, a drive motor is fixedly connected to the front end of the vehicle body 1, and the drive motor is connected to the threaded rod 52 on the right side inside the vehicle body 1. The drive motor drives the threaded rod 52 on the right side, and the threaded rod 52 drives another threaded rod 52 through a transmission belt, which facilitates the stable movement of the clamping platform 55.

[0023] like Figures 1 to 10 As shown, the working process of this large cargo transfer device for import and export is as follows: When loading goods, the worker can press down on the push plate 54, causing the control sleeve 515 on the push plate 54 to move downwards. Because the walls of the W-shaped groove 510 and the V-shaped groove 511 are offset, as shown in the attached diagram... Figure 7 As shown, the spring telescopic rod 513 on the control sleeve 515 moves downward from the top of the V-groove 511 and contacts the bottom wall of the V-groove 511. The spring telescopic rod 513 slides along the bottom wall of the V-groove 511 and gradually approaches the right end of the W-groove 510. At this time, since the inclined surface of the wedge block 512 in the left wall of the W-groove 510 faces the V-groove 511, and the inclined surface of the wedge block 512 in the right wall of the W-groove 510 faces the W-groove 510, the spring telescopic rod 513 passes the wedge block 512. 2. The wedge block 512 enters the W-shaped groove 510. At this time, the inclined surface of the wedge block 512 is in the same direction as the V-shaped groove 511. At the same time, the operator releases the push plate 54, so that when the spring telescopic rod 513 moves to the rear end of the wedge block 512, since there is no inclined surface, the spring telescopic rod 513 follows the control sleeve 515 and is reset downward by the spring. The spring telescopic rod 513 slides along the top groove wall of the W-shaped groove 510 until it is stuck at the top of the W-shaped groove 510. At this time, the push plate 54 is in the ready-to-trigger state. The staff places the goods on the loading plate 4. Optionally, a hydraulic jack can be installed at the bottom of the loading plate 4 to facilitate pushing the loading plate 4 to be level with the vehicle body 1. At this time, because the control sleeve 515 is pressed down, the protrusion 53 on the control sleeve 515 separates from the threaded groove on the threaded rod 52. This allows the threaded rod 52 to drive the clamping platform 55 to move and fit the goods when the drive motor is started, while the control sleeve 515 cannot be driven due to the separation of the protrusion 53. Next, the hydraulic telescopic rod assembly 561 uses the hydraulic telescopic rod to move the two half-clamping blocks 567 relative to each other, clamping the goods at both ends and assisting in pushing the goods forward. When the goods squeeze the push plate 54, the push plate 54 is pressed down again. Similarly, the spring telescopic rod 513 in the control sleeve 515 contacts the groove wall at the bottom of the W-shaped groove 510 and moves to the left along it until the goods are removed from the push plate 54. At this time, the spring telescopic rod 513 passes over the wedge block 512 at the left end. At this time, the push plate 54 rises and resets through the spring in the control sleeve 515, so that the spring telescopic rod 513 slides from the left end of the W-shaped groove 510 into the V-shaped groove 511, so that the spring telescopic rod 513 is stuck at the top of the V-shaped groove 511. As the control sleeve 515 rises and resets, the protrusion 53 in the control sleeve 515 is connected to the threaded groove on the threaded rod 52. At this time, the control sleeve 515 can be driven, so that while the clamping platform 55 set in front moves, the push plate 54 can push the goods forward at the rear end of the goods, reduce the load on the clamping platform 55, and avoid slippage and other phenomena. Finally, the operator can manually move the lever 564, which moves the lever sleeve 565 backward. The lever sleeve 565 pushes the limiting plate 569 to rotate clockwise and move it out of the limiting groove 568. At this time, the operator can remove the half clamping block 567, replace it with a new half clamping block 567, and insert the mounting post 566 into the lever sleeve 565. The mounting post 566 presses the limiting plate 569 to rotate clockwise, so that the limiting plate 569 enters the limiting groove 568. If the half clamping block 567 is pulled out, the limiting groove 568 will push the limiting plate 569 to rotate counterclockwise. However, the limiting plate 569 has a limiting protrusion 5610 at the rear end, which prevents the limiting plate 569 from rotating, thus locking the half clamping block 567 and completing the replacement process.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
