Abstract
Description
Technical Field
[0001] This utility model relates to the field of transfer vehicle technology, specifically to a container loading and unloading transfer vehicle. Background Technology
[0002] Container handling and transshipment vehicles play a vital role in logistics and transportation. These vehicles are also commonly used for transferring goods or containers within factories. They enable rapid and efficient loading, unloading, transportation, and transshipment of containers, significantly improving the overall efficiency of multimodal transport. Characterized by high load-bearing capacity and fast operating speed, transshipment vehicles effectively reduce time and costs during transportation. They are not only suitable for container ports and yards but also enable seamless connections between different modes of transport during road transport. The application of transshipment vehicles strengthens the connection between various links in multimodal transport, promoting its rapid development.
[0003] Containers are loaded by placing them directly onto the top of a transfer vehicle using a crane. However, the top of the transfer vehicle lacks a securing device, allowing the container to easily shift due to inertia during transport, thus affecting its stability. To address this issue, a container loading and unloading transfer vehicle is proposed, which uses deployable pallets to restrain the container from its side, thus resolving the aforementioned problem. Utility Model Content
[0004] This utility model proposes a container loading and unloading transfer vehicle, which solves the problem in related technologies where the container on top of the trailer moves due to inertia during transportation, making it difficult to guarantee the safety of the transfer process.
[0005] The technical solution of this utility model is as follows:
[0006] A container loading and unloading transfer vehicle includes a trailer. A slot is provided at the top of the trailer. A limiting component is provided inside the slot. The limiting component includes sliders symmetrically slidably connected inside the slot. A rotating rod is rotatably connected inside the sliders. A locking plate is rotatably connected between the two rotating rods. A bidirectional lead screw is rotatably connected inside the trailer. The bidirectional lead screw is threadedly connected to the two sliders. A limiting screw is threadedly connected inside the locking plate. One end of the limiting screw is rotatably connected to a limiting suction cup.
[0007] Optionally, the slots are provided in four sets and are rectangular in shape. The limiting component also includes a cavity connecting plate fixedly connected to the rear of the trailer. A clamping plate is fixedly connected inside the cavity connecting plate, and a connecting rod is rotatably connected inside the clamping plate.
[0008] Optionally, the limiting component further includes transmission bevel gears symmetrically fixedly connected to both ends of the connecting rod, and a driven bevel gear is fixedly connected to one end of the bidirectional lead screw, wherein the transmission bevel gear meshes with the driven bevel gear.
[0009] Optionally, the limiting component further includes a servo motor fixedly connected to the bottom end of the cavity connecting plate, the output end of the servo motor being fixedly connected to a connecting bevel gear, the connecting bevel gear being rotatably connected to the inside of the cavity connecting plate, and the connecting bevel gear meshing with one of the sets of transmission bevel gears.
[0010] Optionally, a stop plate is fixedly connected to the top of the trailer, the stop plate is located at the head of the trailer, and a cushioning pad is fixedly connected to the inner side of the stop plate.
[0011] Optionally, the top of the trailer is provided with a chute, the chute is located at the rear of the trailer, and a positioning plate is slidably connected to the top of the chute.

[0028] Example 1
[0029] Reference Figures 1-4 This is the first embodiment of the present invention, which proposes a container loading and unloading transfer vehicle, including a trailer 1. The top of the trailer 1 is provided with a slot 2. The slot 2 is provided with a limiting component 3. The limiting component 3 includes sliders 301 symmetrically slidably connected inside the slot 2. The sliders 301 are rotatably connected with rotating rods 302. A locking plate 303 is rotatably connected between the two rotating rods 302. A bidirectional lead screw 304 is rotatably connected inside the trailer 1. The bidirectional lead screw 304 is threadedly connected to the two sliders 301. A limiting screw 305 is threadedly connected inside the locking plate 303. One end of the limiting screw 305 is rotatably connected to a limiting suction cup 306. The purpose of this setup is that after the container is placed on top of the trailer 1, the double-acting screw 304 inside the trailer 1 is rotated. The rotating double-acting screw 304 causes the two sliders 301 in the slot 2 to slide in opposite directions. At this time, the sliders 301 drive the rotating rods 302 to rotate, and the two rotating rods 302 drive the clamping plate 303 to rise, thereby limiting the side wall of the container. At the same time, rotating the limiting screw 305 causes the limiting suction cup 306 at its outer end to adhere to the side of the container, thereby further clamping and limiting the container, preventing the container from moving laterally on top of the trailer 1 during the rotation of the container.
[0030] Optionally, the slot 2 has four sets arranged in a rectangular shape. The limiting component 3 also includes a cavity connecting plate 307 fixedly connected to the rear of the trailer 1. A clamping plate 308 is fixedly connected inside the cavity connecting plate 307, and a connecting rod 309 is rotatably connected inside the clamping plate 308. The limiting component 3 also includes transmission bevel gears 3010 symmetrically fixedly connected to both ends of the connecting rod 309. One end of the bidirectional lead screw 304 is fixedly connected to a driven bevel gear 3011, and the transmission bevel gear 3010 meshes with the driven bevel gear 3011. The purpose of this arrangement is that during the process of limiting the side wall of the container, the connecting rod 309 drives the transmission bevel gear 3010 to rotate inside the cavity connecting plate 307. Since the transmission bevel gear 3010 meshes with the driven bevel gear 3011, the rotating transmission bevel gear 3010 drives the driven bevel gear 3011 to rotate, thereby causing the two bidirectional lead screws 304 to rotate simultaneously inside the trailer 1.
[0031] Optionally, the limiting component 3 also includes a servo motor 3012 fixedly connected to the bottom end of the cavity connecting plate 307. The output end of the servo motor 3012 is fixedly connected to a connecting bevel gear 3013, which is rotatably connected inside the cavity connecting plate 307. The connecting bevel gear 3013 meshes with one set of transmission bevel gears 3010. The purpose of this arrangement is that the servo motor 3012 drives the connecting bevel gear 3013 to rotate, and the rotating connecting bevel gear 3013 drives the transmission bevel gear 3010 meshing with its outer end to rotate.
[0032] Example 2
[0033] Reference Figures 1-6 This is the second embodiment of the present invention, which differs from the first embodiment in that:
[0034] Compared to Embodiment 1, the trailer 1 is further provided with a stop plate 4 fixedly connected to its top. The stop plate 4 is located at the head of the trailer 1, and a buffer pad is fixedly connected to the inner side of the stop plate 4. The purpose of this arrangement is to provide compression protection for the head of the container by the stop plate 4 and the buffer pad fixed to its inner side.
[0035] Optionally, a groove 5 is provided at the top of the trailer 1, located at the rear of the trailer 1. A positioning plate 6 is slidably connected to the top of the groove 5, and a positioning screw 7 is rotatably connected to the center of the trailer 1. The positioning screw 7 is threadedly connected to the positioning plate 6. The purpose of this arrangement is that after the side wall of the container is clamped and limited, rotating the positioning screw 7 causes the positioning plate 6 to slide in the groove 5 at the top of the trailer 1, thereby clamping the positioning plate 6 from the rear of the container and preventing the container from moving longitudinally during transportation.
[0036] Optionally, a side plate 8 is symmetrically fixedly connected to the rear end of the trailer 1. A support rod 9 is symmetrically slidably connected inside the side plate 8. A baffle plate 10 is fixedly connected to one end of the support rod 9, and a spring 11 is fixedly connected between the side plate 8 and the baffle plate 10. The purpose of this arrangement is that, during reversing, the rear of the trailer 1 is prone to colliding with obstacles, thus affecting the stability of the container on top of the trailer 1. When the rear of the trailer 1 collides with an obstacle, the support rod 9 connected to the baffle plate 10 slides inside the side plate 8, while the spring 11 is compressed. The elastic force generated by the spring 11 acts as a buffer, reducing damage to the container.
[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
