Technical Field

[0001] This utility model relates to the field of cargo sled technology, and specifically discloses a cargo sled platform. Background Technology

[0002] In cold regions, there is usually a lot of snow on the roads in winter, making it difficult for ordinary vehicles to drive on the snow. Usually, people travel on the snow by driving snowmobiles and other snow vehicles. When it is necessary to transport goods on the snow, a ski trailer is usually attached to the rear of the snow vehicle for transporting goods. Cargo sleds are one type of ski trailer.

[0003] Existing ski trailers are not suitable for transporting large containers, and the fixed installation of the ski legs on existing ski trailers results in a large turning radius and insufficient turning flexibility. Therefore, a cargo-carrying ski platform is needed to solve this problem. Utility Model Content

[0022] Please see Figure 1-6 A cargo transport sled platform includes a sled platform body 1, a deceleration beam 6 and a traction fixing frame 7. Telescopic struts 4 are fixedly connected to the four corners of the lower end face of the sled platform body 1. Sled foot supports 2 are fixedly connected to the lower ends of the four telescopic struts 4. Sled foot plates 5 are installed at the lower ends of the four sled foot plates 2. A sled crossbeam 3 is movably arranged between two sled foot plates 5 on the same side.

[0023] The two ends of the left sled crossbeam 3 are fixedly connected to the deceleration beam 6 and the traction fixing frame 7 by iron chains, and the two left sled footboards 5 and the two right sled footboards 5 are connected by iron chains in an alternating manner.

[0024] In this embodiment: the sled platform body 1 is provided with a container corner fitting connection point, which can be conveniently and safely connected to the container through the container twist lock. The connection strength is firm and reliable. In use, by connecting the traction fixing frame 7 to the tractor, when the tractor turns, the tractor pulls the left sled crossbeam 3 to rotate through the iron chain, thereby driving the two sled footboards 5 on the left to rotate synchronously. The two sled footboards 5 on the left are further pulled by the interlaced iron chains (the sled footboard 5 in the front left is connected to the sled footboard 5 in the rear right, and the sled footboard 5 in the rear left is connected to the sled footboard 5 in the front right) to rotate synchronously, thereby driving the sled platform body 1 to turn. The sled footboards 5 and the traction fixing frame 7 are connected front and rear by high-strength iron chains. The strength is reliable and the connection through the iron chains is flexible, making the overall movement of the sled more flexible.

[0025] As a technical optimization of this utility model, the telescopic support rod 4 includes a sleeve 401, a rotating shaft 402 is rotatably connected inside the sleeve 401, and a spring 403 located inside the sleeve 401 is sleeved on the outer wall of the rotating shaft 402.

[0026] In this embodiment, the spring 403 can reduce the vibration of the sled platform body 1 during operation, protecting the cargo from damage.

[0027] As a technical optimization of this utility model, a fence is provided around the upper surface of the sled platform body 1, and a wooden floor is provided on the upper surface of the sled platform body 1.

[0028] In this embodiment, by installing guardrails around the upper surface of the sled platform body 1 and installing wooden flooring on the upper surface of the sled platform body 1, it is possible to prevent goods from falling off the sled platform body 1.

[0029] As a technical optimization of this utility model, the two ends of the sled footboard 5 are arc-shaped, and the bottom is fixedly connected with a wear-resistant plate.

[0030] In this embodiment, by fixing a wear-resistant plate to the bottom of the sled footboard 5, the service life of the sled footboard 5 can be increased.

[0031] As a technical optimization of this utility model, the sled platform body 1, sled foot support 2, sled crossbeam 3, telescopic support rod 4, sled foot plate 5, deceleration beam 6 and traction fixing frame 7 are sequentially provided with pre-treatment zinc-rich primer, secondary sandblasting zinc-rich primer, epoxy intermediate coat and polyurethane topcoat from the inside to the outside.

[0032] In this embodiment, by setting a pre-treatment zinc-rich primer, a secondary sandblasting zinc-rich primer, an epoxy intermediate coat, and a polyurethane topcoat, corrosion and rust of the device are prevented, and its service life is increased.

[0033] The working principle and usage process of this utility model are as follows: The sled platform body 1 is equipped with a container corner fitting connection point, which can be conveniently and safely connected to the container through the container twist lock. The connection strength is firm and reliable. In use, by connecting the traction fixing frame 7 to the tractor, when the tractor turns, the tractor pulls the left sled crossbeam 3 to rotate through the iron chain, which in turn drives the two left sled footboards 5 to rotate synchronously. The two left sled footboards 5 further pull the two right sled footboards 5 to rotate synchronously through the interlaced iron chains, thereby driving the sled platform body 1 to turn. The sled footboards 5 and the traction fixing frame 7 are connected front and rear by high-strength iron chains. The strength is reliable and the connection through the iron chains is flexible, making the overall movement of the sled more flexible.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
