Description

Technical Field

[0001] The utility model relates to the technical field of semi-trailers, in particular to a semi-trailer compartment with double roofs. Background Art

[0002] Semi-trailers are heavy-duty transport vehicles connected to the front of the vehicle by a traction pin, mainly used to transport large goods. In today's rapidly developing society, transportation efficiency has become the first choice for people, and semi-trailers are widely used due to their convenience in hanging and dropping.

[0003] The existing dump trailer mainly includes a frame, a carriage arranged on the frame and a top cover arranged on the carriage. In order to improve the efficiency of loading and unloading materials, some semi-trailers design the top cover to be openable. At present, there are two main structural forms for opening and closing the carriage top cover. One is to adopt a telescopic structural form. This structural form has the problem of insufficient opening and closing efficiency. It can only open a part of the space on the top of the carriage, which also affects the loading and unloading efficiency; the other is to design the top cover to be an open and flip structural form. Its overall structure is complex, and a swing arm is provided in the carriage, which occupies the space in the carriage and requires relatively high costs. Utility Model Content

[0005] Both sides of the top of the box body are provided with slideways, and both sides of the upper cover and the lower cover can be slidably installed in the corresponding slideways;

[0006] The upper cover and the lower cover are both located at the top of the box body, and the upper cover is located above the lower cover;

[0007] The upper cover and the lower cover are each provided with a driving system for controlling the upper cover and the lower cover to move forward and backward along the slideway.

[0008] In some embodiments, the two sides of the upper cover are connected to the upper slider as a whole, and the two sides of the lower cover are connected to the lower slider as a whole;

[0009] For the slideway on either side, the shape of the inner side of the slideway is convex and matches with the concave lower sliding block, and the shape of the outer side of the slideway is concave and matches with the convex upper sliding block.

[0010] In some embodiments, the upper cover and the lower cover are each configured with a chain drive system.

[0011] In some embodiments, the chain drive system includes a drive device, a chain, a driving sprocket, and a driven sprocket;

[0012] The upper cover and the lower cover are mounted on corresponding chains;

[0013] The chain passes around the driving sprocket and the driven sprocket to form a closed loop;

[0014] The driving device is used to drive the driving sprocket to rotate forward and reverse.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows: the double-top semi-trailer carriage provided by the utility model has two upper and lower covers that can slide along the slideway, and the two covers are independently controlled by different drive systems, and the movements of the two covers do not affect each other, so that different positions of the top of the carriage can be opened or closed, thereby improving the opening and closing efficiency, and being conducive to completing loading and unloading according to different needs; it also has the advantages of simple structure, stable and reliable operation, and low cost.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the following further describes how the present invention is implemented in conjunction with the accompanying drawings and specific implementation methods.

[0023] Reference Figure 1-Figure 3 As shown, the utility model provides a semi-trailer compartment with double top covers, comprising a box body 1, an upper top cover 3 and a lower top cover 5; slideways 2 are provided on both sides of the top of the box body 1, and both sides of the upper top cover 3 and the lower top cover 5 can be slidably installed in the corresponding slideways 2; the upper top cover 3 and the lower top cover 5 are both located at the top of the box body 1, and the upper top cover 3 is located above the lower top cover 5; the upper top cover 3 and the lower top cover 5 are each configured with a set of driving systems for controlling the upper top cover 3 and the lower top cover 5 to move forward and backward along the slideway 2.

[0024] Preferably, the two sides of the upper top cover 3 are connected as a whole with the upper slider 4, and the two sides of the lower top cover 5 are connected as a whole with the lower slider 6; for the slide 2 on either side, the shape of the inner side of the slide 2 is convex and cooperates with the concave lower slider 6, and the shape of the outer side of the slide 2 is concave and cooperates with the protruding upper slider 4.

[0025] Further references Figure 4 As shown, preferably, the upper cover 3 and the lower cover 5 are each equipped with a chain drive system.

[0026] Preferably, the chain drive system includes a drive device, a chain, a driving sprocket 7 and a driven sprocket 8; the upper cover 3 and the lower cover 5 are mounted on the corresponding chain; the chain passes around the driving sprocket 7 and the driven sprocket 8 to form a closed loop; the drive device is used to drive the driving sprocket 7 to rotate forward and reverse. It can be understood that the drive device can be a motor or an electric motor; when the drive device controls the corresponding driving sprocket 7 to rotate forward or reverse, the corresponding cover moves forward or backward with the chain.

[0027] The double-top semitrailer compartment provided by the utility model has an upper cover 3 and a lower cover 5 which can move independently and slide forward and backward along the slideway 2. The upper cover 3 and the lower cover 5 can move to the front end and the rear end of the box body 1 respectively, and can also stop at any position in the middle of the box body 1. Figure 3 In the illustrated case, when the upper cover 3 and the lower cover 5 are located at the two ends respectively, the top of the box body 1 is closed.

[0028] In summary, the double-top semi-trailer carriage provided by the utility model has two upper and lower covers that can slide along the slideway, and the two covers are independently controlled by different drive systems, and the movements of the two covers do not affect each other, so that different positions of the top of the carriage can be opened or closed, which improves the opening and closing efficiency and is conducive to loading and unloading according to different needs; it also has the advantages of simple structure, stable and reliable operation, and low cost.
