Technical Field

[0001] This utility model relates to the field of container transport semi-trailer technology, and in particular to a container transport semi-trailer with a fast loading and unloading function. Background Technology

[0002] A semi-trailer is a trailer with its axle positioned behind the vehicle's center of gravity and equipped with a coupling device that transmits horizontal and vertical forces to the tractor unit. It is a heavy-duty transport vehicle connected to a semi-trailer unit via a towing pin. Semi-trailers are generally three-axle trailers, and come in various types such as 11-meter stake semi-trailers, 13-meter stake semi-trailers, and low-flatbed semi-trailers. Semi-trailers are primarily used to transport large, difficult-to-disassemble cargo, such as excavators and containers. In the logistics industry, container transport is a common mode of transportation, requiring the use of semi-trailers to transport containers.

[0003] Existing container transport semi-trailers require rapid loading and unloading of containers during transport. However, containers are relatively fixed on the trailer, making it inconvenient to quickly push and pull them. Furthermore, loading and unloading containers on the semi-trailer requires manual operation or the use of other equipment, which is not very stable.

[0004] Therefore, a container semi-trailer with rapid loading and unloading function is provided to solve the problems mentioned above. Utility Model Content

[0028] The push-pull mechanism includes a first hydraulic telescopic rod 9, a mounting frame 11, and a clamping plate 13. The first hydraulic telescopic rod 9 is mounted on the top of the support plate 2. The mounting frame 11 is fixedly mounted on the extended end of the first hydraulic telescopic rod 9.

[0030] In use, by setting the mounting frame 11, gear 20, adjusting plate 12 and clamping plate 13 on the side of the support plate 2, when the container is supported on the vehicle plate 3 by the support roller 8, the first hydraulic telescopic rod 9 moves to extend and retract, driving the mounting frame 11, adjusting plate 12 and clamping plate 13 to move. The container can be unloaded quickly, easily and stably through the mounting frame 11 and adjusting plate 12.

[0031] Example 2: A container transport semi-trailer with rapid loading and unloading function, such as Figures 1-5 As shown, the first hydraulic telescopic rod 9 is set horizontally, the mounting frame 11 is a rectangular frame structure and is set horizontally, the top plate 23 is fixed at the top center of the mounting frame 11, the gear 20 is rotatably mounted in the middle of the mounting frame 11, the gear 20 is set vertically, the top of the gear 20 is connected to the motor 10, and the motor 10 is fixedly mounted at the top of the top plate 23.

[0032] The mounting frame 11 has guide grooves 22 at both ends. An adjusting plate 12 slides through the inside of the guide groove 22 and on both sides of the gear 20. Teeth 24 are evenly fixed on the inner side of the adjusting plate 12. The teeth 24 mesh with the gear 20 for transmission. The adjusting plate 12 has a rectangular plate structure.
