Technical Field

[0001] This application relates to the field of semi-trailers, and more particularly to a semi-trailer with adjustable sideboards. Background Technology

[0002] Semi-trailers, thanks to their reasonable structural design and sturdy frames and axles, can carry a large amount of cargo. Compared with ordinary trucks, their cargo capacity is significantly increased, which makes them play an important role in logistics transportation, especially in the transportation of bulk commodities and large equipment.

[0003] However, traditional semi-trailers have fixed sideboard positions and are relatively long. When loading, cargo can only be loaded from the rear and top of the semi-trailer, which is slow and cannot be used for loading different sections of the vehicle, making the loading process quite troublesome. Utility Model Content

[0004] To facilitate the adjustment of the sideboard position and thus make it easier to load goods at different locations on the vehicle, thereby improving loading convenience, this application provides a semi-trailer with adjustable sideboards.

[0005] This application provides a semi-trailer with adjustable sideboards, which adopts the following technical solution:

[0006] An adjustable-sideboard semi-trailer includes a frame with an adjustment structure. The adjustment structure includes a retaining frame, a U-shaped retaining frame fixedly connected to the frame, a first U-shaped sideboard slidably connected inside the retaining frame, the first sideboard being slidably connected to the frame, a second sideboard slidably connected inside the first sideboard, the second sideboard being slidably connected to the frame, a first lead screw and a second lead screw rotatably connected to the frame, the first lead screw being threadedly connected to the first sideboard, a first motor and a second motor fixedly connected to the frame, the output end of the first motor being fixedly connected to the first lead screw, the second lead screw being threadedly connected to the second sideboard, the output end of the second motor being fixedly connected to the second lead screw, a guide rod fixedly connected to the frame, and the second sideboard being slidably connected to the guide rod.

[0007] By adopting the above technical solution, when loading cargo onto a semi-trailer, the positions of the first and second sideboards can be adjusted. First, when loading cargo at the front of the trailer, the first motor can be started. The first motor drives the first lead screw to rotate, and the lead screw thread drives the first sideboard to slide between the side frame and the chassis until the first and second sideboards overlap. At this point, the front cargo can be loaded. When loading the middle and rear cargo, the first motor can be started to drive the first sideboard back to its initial position. Then, the second motor can be started, driving the second lead screw to rotate. The second lead screw thread drives the second sideboard to slide between the first sideboard and the chassis, moving the second sideboard until it overlaps with the first sideboard. Then, the middle and rear cargo can be loaded. This allows for convenient adjustment of the sideboard positions, thus improving loading convenience.

[0008] Optionally, the top of the first guardrail has a U-shaped cross-section, and multiple first rollers are rotatably connected to the first guardrail, with the first rollers being rotatably connected to the guard frame.

[0009] By adopting the above technical solution, by installing a first roller at the top of the first railing, the first roller rolls with the guard frame, adjusting the sliding friction to rolling friction, making the first railing move more smoothly.

[0010] Optionally, the bottom of the second side panel has a U-shaped cross-section, and multiple second rollers are rotatably connected to the second side panel, with the second rollers being rotatably connected to the vehicle frame.

[0011] By adopting the above technical solution, by installing a second roller on the second sideboard, the second roller rolls with the frame, changing the sliding friction to rolling friction, making the movement of the second sideboard smoother.

[0012] Optionally, a top frame is fixedly connected to the top of the vehicle frame, and a protective structure is provided on the top frame. The protective structure includes a pivot, and a protective plate is fixedly connected to the pivot and rotatably connected to the top frame.

[0013] By adopting the above technical solution, the goods at the top are protected by a protective structure. At the same time, the protective structure is easy to open and close, making it easy to lift heavier goods directly from the top into the interior of the vehicle frame using hoisting equipment, thus reducing the difficulty of loading.

[0014] Optionally, a worm gear is fixedly connected to the end of the rotating shaft, and a worm is rotatably connected to the top frame, the worm meshing with the worm gear.

[0015] By adopting the above technical solution, the rotation angle of the protective plate and the rotating shaft can be controlled through the self-locking of the worm gear and worm, thus preventing the protective plate from rotating freely.

[0016] Optionally, a third motor is fixedly connected to the top frame, and the output end of the third motor is fixedly connected to the worm gear.

[0017] By adopting the above technical solution, when loading needs to be done from the top, the third motor on the top frame can be started. The third motor drives the worm gear to rotate, the worm gear drives the worm wheel to rotate, the worm wheel drives the shaft to rotate, and the shaft rotation in turn drives the protective plate to rotate, thereby realizing the opening and closing of the protective plate.

[0018] Optionally, the frame is provided with a partition structure, the partition structure includes a fixing seat, a plurality of fixing seats are fixedly connected to the frame, the fixing seat is provided with a slot, and a partition plate is inserted into the slot.

[0019] By adopting the above technical solution and setting up a partition structure on the chassis, it is easy to divide the goods into sections. After the goods are stored in sections according to different categories, attributes and other factors, the managers can quickly locate the storage location of the goods.

[0020] Optionally, the plurality of the fixing seats are arranged linearly, the slot has a T-shaped cross-section, and the end cross-section of the partition plate has a T-shaped cross-section.

[0021] By adopting the above technical solution, the T-shaped structure design of the slot and the partition plate improves the stability when the partition plate tends to separate.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. During loading, the first motor and the second motor can be started, which will drive the first lead screw or the second lead screw to rotate. The first lead screw and the second lead screw will drive the first sideboard and the second sideboard to move, making it easy to adjust the position of the sideboard. This facilitates loading of goods at different locations on the vehicle, thereby improving the convenience of loading.

[0024] 2. The protective structure protects the cargo at the top of the trailer, and the structure is easy to open and close, making it convenient to load heavy cargo from the top of the trailer using lifting equipment;

[0025] 3. By dividing goods into sections using a partitioned structure, and storing goods according to different categories, attributes, and other factors, managers can quickly locate the storage location of the goods. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-13 This application will be described in further detail.

[0041] This application discloses a semi-trailer with adjustable sideboards. (Refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 An adjustable-sideboard semi-trailer includes a frame 1, on which an adjustment structure 3 is provided.

[0042] The first motor 305 drives the first lead screw 304 to rotate. The first lead screw 304 threadedly drives the first side panel 302 to slide between the baffle 301 and the frame 1 until the first side panel 302 and the second side panel 303 are aligned. At this point, the front section of goods can be loaded. When it is necessary to load the middle and rear sections of goods, the first motor 305 can be started to drive the first side panel 302 back to the initial position. Then, the second motor 308 can be started, and the second motor 308 drives the second lead screw 307 to rotate. The second lead screw 307 threadedly drives the second side panel 303 to slide between the first side panel 302 and the frame 1, thereby moving the second side panel 303 to overlap with the first side panel 302. Then, the middle and rear sections of goods can be loaded. This makes it easy to adjust the position of the side panel, thereby improving the convenience of loading.

[0043] The first guardrail 302 has a U-shaped cross-section at its top end, and multiple first rollers 306 are rotatably connected to the first guardrail 302. The first rollers 306 are rotatably connected to the baffle frame 301. The second guardrail 303 has a U-shaped cross-section at its bottom end, and multiple second rollers 309 are rotatably connected to the second guardrail 303. The second rollers 309 are rotatably connected to the frame 1. By installing the first rollers 306 at the top end of the first guardrail 302, the first rollers 306 and the baffle frame 301 roll, changing the sliding friction to rolling friction, making the first guardrail 302 move more smoothly. The second rollers 309 are installed on the second guardrail 303, causing the second rollers 309 to roll with the frame 1, changing the sliding friction to rolling friction, making the second guardrail 303 move more smoothly.

[0044] Reference Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 A rotating shaft 401 is rotatably connected to the top frame 2, and a protective plate 402 is fixedly connected to the rotating shaft 401; a worm gear 403 is fixedly connected to the end of the rotating shaft 401, and a worm 404 is rotatably connected to the top frame 2, the worm 404 meshing with the worm gear 403; a third motor 405 is fixedly connected to the top frame 2, and the output end of the third motor 405 is fixedly connected to the worm 404.

[0045] By setting up a protective structure 4 to protect the goods at the top, and by making the protective structure 4 easy to open and close, it is easy to use hoisting equipment to directly lift heavier goods from the top into the interior of the frame 1, reducing the difficulty of loading. The worm gear 403 and worm 404 are self-locking, which can control the rotation angle of the protective plate 402 and the rotating shaft 401, preventing the protective plate 402 from rotating freely. When it is necessary to load goods from the top, the third motor 405 on the top frame 2 can be started. The third motor 405 drives the worm 404 to rotate, the worm gear 404 drives the worm gear 403 to rotate, the worm gear 403 drives the rotating shaft 401 to rotate, and the rotating shaft 401 drives the protective plate 402 to rotate, thus realizing the opening and closing of the protective plate 402.

[0046] Reference Figure 7 , Figure 12 and Figure 13 The frame 1 is fixedly connected to a plurality of fixed seats 501, and the fixed seats 501 are provided with slots 502, and partition plates 503 are inserted into the slots 502;

[0047] By setting a partition structure 5 on the frame 1, it is easy to divide the goods into sections. After the goods are stored in sections according to different categories, attributes and other factors, the managers can quickly locate the storage location of the goods. The T-shaped structure design of the slot 502 and the partition plate 503 improves the stability of the partition plate 503 when the separation tends to be.

[0048] This application discloses an implementation principle of an adjustable-sideboard semi-trailer: When loading cargo onto the semi-trailer, the positions of the first sideboard 302 and the second sideboard 303 can be adjusted. Firstly, when loading cargo into the front of the trailer, the first motor 305 can be started. The first motor 305 drives the first lead screw 304 to rotate. The lead screw 304 threadedly drives the first sideboard 302 to slide between the retaining frame 301 and the chassis 1 until the positions of the first sideboard 302 and the second sideboard 303 coincide, at which point the front section can be loaded. When it is necessary to load the middle and rear sections of cargo, the first motor 305 can be activated to drive the first sideboard 302 back to its initial position. Then, the second motor 308 can be activated, driving the second lead screw 307 to rotate. The lead screw 307 threadedly drives the second sideboard 303 to slide between the first sideboard 302 and the frame 1, thereby moving the second sideboard 303 to overlap with the position of the first sideboard 302. Then, the middle and rear sections of cargo can be loaded. This allows for easy adjustment of the sideboard position, thereby improving loading efficiency. Convenience: The protective structure 4 protects the goods at the top, and it is easy to open and close, allowing heavier goods to be lifted directly from the top into the frame 1 using hoisting equipment, reducing loading difficulty. The self-locking mechanism of the worm gear 403 and worm 404 controls the rotation angle of the protective plate 402 and the rotating shaft 401, preventing the protective plate 402 from rotating freely. When loading from the top, the third motor 405 on the top frame 2 can be activated. The third motor 405 drives the worm 404 to rotate, which in turn drives the worm gear 403 to rotate. The worm gear 403 drives the rotating shaft 401 to rotate, which in turn drives the protective plate 402 to rotate, thus opening and closing the protective plate 402. The partition structure 5 on the frame 1 facilitates the partitioning of goods. After the goods are stored in partitions according to different categories, attributes, and other factors, the management personnel can quickly locate the storage location of the goods. The T-shaped design of the slot 502 and the partition plate 503 improves the stability of the partition plate 503 when the partition is close to the center.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
