Technical Field

[0001] The utility model relates to the technical field of semi-trailers, in particular to a novel lightweight refrigerated van semi-trailer. Background Art

[0002] Refrigerated van semi-trailer is a type of semi-trailer, mainly used in cold chain logistics to transport goods with preservation requirements and specific temperature requirements. Its basic function is to keep the goods from rotting and deterioration during the entire transportation process under any external environmental conditions.

[0034] Figure 1 It is a schematic diagram of the overall structure of a new lightweight refrigerated van semi-trailer according to one embodiment of the present disclosure.

[0035] like Figure 1-Figure 4 As shown, the novel lightweight refrigerated van semi-trailer disclosed in the present invention may include: a vehicle body 1, a vehicle compartment 2, a partition mechanism 3, an extension mechanism 4, a material pushing mechanism 5 and other components.

[0036] Figure 2 It is a schematic structural diagram of a partition mechanism 3 of a novel lightweight refrigerated van semi-trailer according to an embodiment of the present disclosure.

[0037] like Figure 2 As shown, in the present disclosure, the partition mechanism 3 includes a dual-axis motor 31, two groups of traction components and a partition plate 35, the traction component includes a winding roller 32, a wire rope 33 and two guide rollers 34, wherein the dual-axis motor 31 is fixedly arranged on the top of the inner cavity of the carriage 2, the partition plate 35 is located at the bottom of the inner cavity of the carriage 2, the winding roller 32 is rotatably nested on the inner wall of the carriage 2 through a bearing and is transmission-connected to the dual-axis motor 31, the wire rope 33 is fixedly passed through the winding roller 32 and both ends thereof are fixedly connected to the partition plate 35, the guide roller 34 is rotatably nested on the inner wall of the carriage 2 through a bearing, and the wire rope 33 is slidingly fitted with the outer wall of the guide roller 34.

[0038] In this way, the dual-axis motor 31 drives the winding roller 32 to rotate, and the winding roller 32 reels the wire rope 33 when rotating. During this process, the guide roller 34 guides the wire rope 33. At this time, the partition plate 35 drives the extension mechanism 4, the pushing mechanism 5 and the guide support mechanism 6 to continue to rise on the inside of the carriage 2, and then the operator can put the goods into the bottom of the inner cavity of the carriage 2 for stacking.

[0039] Figure 3 It is a schematic structural diagram of an extension mechanism 4 and a guide support mechanism 6 of a novel lightweight refrigerated van semi-trailer according to an embodiment of the present disclosure.

[0046] Therefore, after a batch of goods is placed on the top of the extension plate 41, the driving motor 54 drives the driving screw 53 to rotate. When the driving screw 53 rotates, the push plate 51 is driven to move continuously to the left through the slider 52. During the left movement of the push plate 51, the goods on the top of the extension plate 41 are pushed, and then the goods are moved from the top of the extension plate 41 to the top of the partition plate 35, and then the goods are pushed continuously to reach the left end of the top of the partition plate 35. Then the driving motor 54 drives the driving screw 53 to reverse, and then the pushing plate 51 is reset. Then the next batch of goods is placed and the above-mentioned pushing operation is repeated until the goods are placed.
