Description

Technical Field

[0001] This utility model relates to the field of transportation equipment technology, specifically to a rear-unloading semi-trailer bottom plate. Background Technology

[0002] Rear-dump semi-trailers are key equipment for material transportation and transshipment and are widely used in the logistics field. Their floor plates need to withstand the impact loads of the transshipped materials and the weight loads of the materials themselves for a long time. Therefore, impact resistance and bending performance are the core indicators that determine the service life of the floor plates.

[0003] Currently, the demand for lightweight rear-dump semi-trailers is increasingly strong, but most mainstream rear-dump semi-trailer floorboards still adopt a flatbed structure design. While this structure is easy to process and has low manufacturing costs, it has more significant drawbacks in the context of lightweight trends and practical applications: On the one hand, lightweight vehicles have thinner floorboards to achieve weight reduction goals, and flatbed floorboards are prone to deformation during welding due to uneven stress distribution, directly affecting the flatness and assembly accuracy of the floorboards; on the other hand, the flatbed structure itself lacks targeted anti-deformation reinforcement design. During loading and unloading, the instantaneous impact of falling materials can easily cause local stress concentration in the floorboards, leading to dents and bending deformations. Moreover, after long-term static loads from the weight of materials, the overall bending resistance of the flatbed floorboards is insufficient, easily resulting in problems such as central deflection and edge cracking, seriously affecting the service life of the floorboards and increasing the user's maintenance costs. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a rear-discharge semi-trailer floorboard. Utilizing an anti-deformation structure design, it enhances the floorboard's impact resistance during material handling. Compared to conventional flatbed floorboards, it effectively improves the floorboard's bending resistance and significantly extends its service life.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rear-unloading semi-trailer bottom plate, including a frame, a load-bearing plate in the middle of the frame, the load-bearing plate including a base, an anti-deformation structure on the base, and connecting extension plates on both sides of the base.

[0006] As a further improvement to the above technical solution:

[0007] The anti-deformation structure includes upwardly bent anti-bending protrusions, and there are multiple anti-bending protrusions distributed sequentially along the width direction of the substrate.

[0008] The anti-bending protrusions are arranged along the length of the substrate, and each anti-bending protrusion has a transition plate on both sides. The angle between the anti-bending protrusions and the transition plates is 130-160 degrees.

[0009] The height of the anti-bending protrusion is 5-12 mm, and the distance between two adjacent anti-bending protrusions is the same as the width of the anti-bending protrusion.

[0010] The deformation-resistant structure includes multiple reinforcing ribs evenly distributed along the width direction of the substrate, with pressure ribs provided between adjacent reinforcing ribs.

[0011] The reinforcing rib includes two V-shaped splicing plates with an included angle of 30-50 degrees.

[0012] The height of the reinforcing rib is 3-5 cm, and the height of the reinforcing rib is greater than the height of the pressure rib.

[0013] The width of the reinforcing rib is 3-5 cm, the distance between two adjacent reinforcing ribs is 30-50 cm, and the pressure rib is located in the middle of the two reinforcing ribs.

[0014] The beneficial effects of this utility model embodiment are as follows: The rear unloading semi-trailer bottom plate includes a frame, a load-bearing plate is installed in the middle of the frame, the load-bearing plate includes a base, an anti-deformation structure is provided on the base, and connecting extension plates are provided on both sides of the base and welded and fixed to the side plates of the frame. The anti-bending protrusion is set along the length direction of the base and is integrally formed with the base by stamping. Each anti-bending protrusion has a transition plate on both sides. The anti-bending protrusion can strengthen the compressive strength of the bottom plate and improve the longitudinal strength of the bottom plate when bearing the pressure applied by the material. Especially when transporting box-type goods, it also has a good bearing effect and ensures that the bottom of the material is placed stably.

[0015] The anti-deformation structure includes multiple reinforcing ribs evenly distributed along the width of the base, with ribs between adjacent reinforcing ribs. It is mainly used for loading and unloading bulk cargo (such as granular or powdery materials). Since the density of bulk cargo is greater than that of boxed cargo, and the impact force on the bottom plate during loading is also greater, a combination of reinforcing ribs and compression structures is used to strengthen the lateral bending resistance of the bottom plate.

[0020] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0021] Example 1

[0022] like Figure 1-2 As shown, the rear unloading semi-trailer bottom plate of this embodiment includes a frame 1, a load-bearing plate 2 installed in the middle of the frame 1, the load-bearing plate 2 includes a base 3, an anti-deformation structure 4 is provided on the base 3, and connecting extension plates 5 are provided on both sides of the base 3 and welded and fixed to the side plates of the frame 1.

[0023] The anti-deformation structure 4 includes upward bending anti-bending protrusions 6. There are multiple anti-bending protrusions 6, which are distributed sequentially along the width direction of the base 3 and are distributed in a wave-like manner.

[0024] The anti-bending protrusions 6 are arranged along the length of the base 3 and integrally formed with the base 3 by stamping. Each anti-bending protrusion 6 has a transition plate 7 on both sides. The angle between the anti-bending protrusion 6 and the transition plate 7 is 130-160 degrees, preferably 145 degrees in actual operation. The height of the anti-bending protrusion 6 is 5-12 mm, preferably 8 mm. The distance between two adjacent anti-bending protrusions 6 is the same as the width of the anti-bending protrusion 6. By selecting the angle and height, the support effect of the anti-bending protrusions 6 is optimized. In this embodiment, the anti-bending protrusions 6 can enhance the compressive strength of the vehicle floor and improve the longitudinal strength of the vehicle floor when bearing the pressure applied by materials. When connected to the frame, all welding points are designed on the base. Figure 2 The vehicle floor provided in this embodiment is mainly used for transporting pallets or materials with a flat lower surface. When in contact with materials, it can not only enhance the bending resistance of the vehicle floor, but also prevent the weld points from cracking or the vehicle floor from being damaged when the materials come into contact with the weld points during friction, thus extending the service life of the vehicle floor.

[0025] Example 2

[0026] The similarities with Example 1 will not be repeated here; the differences are as follows: Figure 3 As shown, the anti-deformation structure 4 includes multiple reinforcing ribs 8 evenly distributed along the width direction of the base 3. A clamping rib 9 is provided between two adjacent reinforcing ribs 8. Both the reinforcing ribs 8 and the clamping rib 9 are integrally formed with the base 3. The reinforcing ribs 8 include two splicing plates 10 distributed in a V-shape. The included angle between the two splicing plates 10 is 30-50 degrees, and the top of the two splicing plates 10 is designed with a rounded arc.

[0027] The height of the reinforcing rib 8 is 3-5 cm, which is greater than the height of the rib 9. The height of the rib is 2-3 cm, the width of the reinforcing rib 8 is 3-5 cm, the distance between two adjacent reinforcing ribs 8 is 30-50 cm, and the rib 9 is located in the middle of the two reinforcing ribs 8.

[0028] In this embodiment, the vehicle floor is mainly used for loading and unloading bulk cargo (such as granular, powdery materials). Since the density of bulk cargo is greater than that of boxed cargo, and the impact force on the floor is also greater during loading, a combination of two structures, reinforcing ribs 8 and clamping 9, is selected to strengthen the lateral bending resistance of the floor.
