Description

Technical Field

[0001] This utility model relates to the field of semi-trailer technology, and in particular to a side-dump semi-trailer frame and a side-dump semi-trailer. Background Technology

[0002] Side-tipping semi-trailers are widely used in the transportation of coal, sand, gravel, and powdered minerals. Current side-tipping semi-trailers have a flat floor structure, resulting in a high load-bearing surface and a high center of gravity, posing safety risks during cargo transport. Furthermore, when lifting and unloading cargo with a large angle of repose, side-tipping semi-trailers require extending the lifting cylinder stroke and increasing the lifting angle of the cargo box, thus introducing certain safety risks. Utility Model Content

[0003] One objective of this invention is to address the shortcomings of existing technologies, such as high load-bearing surface, high center of gravity, and high safety risks caused by large lifting angles, by providing a side-discharge semi-trailer frame. To solve the above technical problems, this invention adopts the following technical solution:

[0004] A side-dump semi-trailer frame includes two side longitudinal beams and two main longitudinal beams located between the two side longitudinal beams, as well as two end crossbeams that are vertically connected between the two side longitudinal beams respectively.

[0005] Each main longitudinal beam includes a gooseneck beam and a main beam connected front and rear. The top plane of the main beam is flush with the top plane of the side longitudinal beam, the top plane of the gooseneck beam is higher than the top plane of the main beam, and the bottom plane of the gooseneck beam is higher than the bottom plane of the main beam.

[0006] Multiple parallel and spaced support beams are provided between the gooseneck beam near the unloading side of the frame and the corresponding side longitudinal beam. The two ends of each support beam are fixedly connected to the gooseneck beam and the corresponding side longitudinal beam, respectively. The top surface of the multiple support beams can form an inclined surface that connects the top plane of the gooseneck beam and the top plane of the corresponding side longitudinal beam. The inclined surface slopes downward toward the unloading side of the frame.

[0007] In one embodiment, the semi-trailer frame is a single-sided unloading frame, and the semi-trailer frame also includes a gooseneck side beam. The gooseneck side beam is longitudinally arranged on the top plane of the side longitudinal beam corresponding to the gooseneck beam away from the unloading side of the frame, and the top plane of the gooseneck side beam is flush with the top plane of the gooseneck beam.

[0008] Alternatively, the semi-trailer chassis may be a double-sided unloading chassis.

[0009] In one embodiment, a plurality of first wing supports are provided between the gooseneck side beams and the gooseneck beams at intervals. Each first wing support is arranged in a transverse direction. One end of each first wing support is fixedly connected to the gooseneck beam, and the other end is fixedly connected to the gooseneck side beam and the corresponding side longitudinal beam. The top plane of each first wing support does not exceed the top plane of the gooseneck beam.

[0010] In one embodiment, a plurality of first cross braces are arranged at intervals between the two gooseneck beams. Each first cross brace is arranged laterally, and both ends of each first cross brace are fixedly connected to the two gooseneck beams respectively. The top plane of each first cross brace does not exceed the top plane of the gooseneck beam.

[0011] In one embodiment, the semi-trailer frame further includes a first reinforcing brace arranged longitudinally between two gooseneck beams. The top surface of each first cross brace is provided with a downwardly recessed first groove. The first reinforcing brace is fixedly installed in the first groove, and the top surface of the first reinforcing brace is flush with the top surface of the gooseneck beam.

[0012] In one embodiment, a plurality of second cross braces are provided between the two main beams at intervals. Each second cross brace is arranged in the transverse direction, and both ends of each second cross brace are fixedly connected to the two main beams respectively. The top plane of each second cross brace does not exceed the top plane of the main beam.

[0013] Multiple second wing braces are arranged at intervals between each main beam and the corresponding side longitudinal beam. Each second wing brace is arranged in the transverse direction. One end of each second wing brace is fixedly connected to the main beam, and the other end is fixedly connected to the corresponding side longitudinal beam. The top plane of each second wing brace does not exceed the top plane of the main beam.

[0014] In one embodiment, the semi-trailer frame also includes a plurality of second reinforcing braces arranged longitudinally between two main beams and between the main beams and the corresponding side longitudinal beams;

[0015] Each second cross brace has a downward-recessed second groove on its top surface, and each second wing brace has a downward-recessed third groove on its top surface. Multiple second reinforcing braces are fixedly installed in the second groove and the third groove respectively, and the top surface of each second reinforcing brace is flush with the top surface of the main beam.

[0016] In one embodiment, the semi-trailer frame also includes multiple main crossbeams, which are arranged in parallel and spaced apart between two side longitudinal beams, and the two ends of each main crossbeam are fixedly connected to the two side longitudinal beams respectively.

[0017] Each main crossbeam is connected perpendicularly to the two main beams, and the top plane of each main crossbeam is flush with the top plane of the main beam.

[0018] One objective of this utility model is to provide a side-dump semi-trailer, including a vehicle body and a side-dump semi-trailer frame as described in any of the preceding claims, wherein the vehicle body has a gooseneck structure and the side-dump semi-trailer frame is foldably mounted on the vehicle body.

[0019] In one embodiment, the side-dump semi-trailer also includes a cargo box floor, which is fitted onto the top bearing surface of the side-dump semi-trailer frame.

[0020] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects:

[0021] In this invention, the frame includes two side longitudinal beams, two main longitudinal beams, and two end crossbeams. Each main longitudinal beam includes a gooseneck beam and a main beam connected front and rear. The gooseneck beam is set higher than the main beam, and the main longitudinal beams have a gooseneck structure, making the overall frame have a gooseneck structure. This effectively reduces the height of the frame's load-bearing surface, lowers the center of gravity of the cargo, and improves transportation safety.

[0022] Furthermore, multiple supporting crossbeams are installed between the gooseneck beam and the corresponding side longitudinal beam on the unloading side. Each supporting crossbeam connects to the higher gooseneck beam and the lower side longitudinal beam at both ends, meaning each supporting crossbeam is arranged at an angle. The top surfaces of these supporting crossbeams form an inclined surface that slopes downwards towards the unloading area. This inclined surface smoothly guides the cargo from the top of the gooseneck beam to the side beam during unloading, thereby improving the smoothness of unloading, accelerating the unloading speed, and effectively preventing cargo accumulation. This new type of chassis eliminates the need for extended lifting cylinder strokes and increased cargo box lifting angles in traditional technologies during side unloading, resulting in higher safety and more convenient unloading.

[0032] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0033] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back) are merely for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] Please see Figure 1 and Figure 2 As shown, this utility model embodiment provides a side-dump semi-trailer, which includes a vehicle body 10 and a side-dump semi-trailer frame (hereinafter referred to as frame 20). For ease of description, it is now defined that the direction of travel of the vehicle is the longitudinal direction, that is, the front-to-back direction of the vehicle; and the direction perpendicular to the longitudinal direction is the transverse direction, that is, the left-to-right direction of the vehicle.

[0036] The vehicle body 10 can be a gooseneck structure to lower the cargo bearing surface and reduce the center of gravity of the cargo. For example, the vehicle body 10 may include two longitudinal beams, each extending longitudinally. The front end of each longitudinal beam is higher than its rear end, thus forming a gooseneck structure.

[0037] The frame 20 is mounted on the vehicle body 10 in a tiltable manner. For example, one lateral side of the frame 20 can be hinged to the vehicle body 10. The vehicle body 10 may be equipped with a lifting unit, and the lifting rod of the lifting unit can be hinged to the centerline of the bottom of the frame 20. When the lifting rod is lifted upward, it can cause the frame 20 to tilt relative to the vehicle body 10, thereby enabling side unloading of goods on the frame 20.

[0038] In this invention, the frame 20 is mainly used to install the cargo box for loading coal, sand, and gravel. For example, the cargo box may include a floor, a front panel, a rear panel, a left panel, and a right panel. The floor can be fitted against the load-bearing surface on top of the frame 20.

[0039] The specific embodiments of the frame 20 of this utility model will be described in detail below with reference to the accompanying drawings.

[0040] Please see Figure 3 and Figure 4 As shown, the frame 20 includes two side longitudinal beams 100 and two main longitudinal beams 200 located between the two side longitudinal beams 100, as well as two end crossbeams 300 that are vertically connected between the two side longitudinal beams 100.

[0041] Each main longitudinal beam 200 includes a gooseneck beam 210 and a main beam 220 connected front and rear. The top plane of the main beam 220 is flush with the top plane of the side longitudinal beam 100. The top plane of the gooseneck beam 210 is higher than the top plane of the main beam 220, and the bottom plane of the gooseneck beam 210 is higher than the bottom plane of the main beam 220.

[0042] Multiple parallel, spaced-apart support beams 500 are provided between the gooseneck beam 210 and the corresponding side longitudinal beam 100 near the unloading side of the frame 20. The two ends of each support beam 500 are fixedly connected to the gooseneck beam 210 and the corresponding side longitudinal beam 100, respectively. The top surfaces of the multiple support beams 500 can form an inclined surface 510 connecting the top plane of the gooseneck beam 210 and the top plane of the corresponding side longitudinal beam 100. The inclined surface 510 slopes downwards towards the unloading side of the frame 20.

[0043] In this invention, each main longitudinal beam 200 includes a gooseneck beam 210 and a main beam 220 connected front and rear. The gooseneck beam 210 is positioned higher than the main beam 220. The main longitudinal beams 200 have a gooseneck structure, making the frame 20 have a gooseneck structure overall. This effectively reduces the height of the load-bearing surface of the frame 20, lowers the center of gravity of the cargo, and improves transportation safety. Furthermore, multiple supporting crossbeams 500 are provided between the gooseneck beam 210 on the unloading side and the corresponding side longitudinal beam 100. The two ends of each supporting crossbeam 500 can be connected to the higher gooseneck beam 210 and the lower side longitudinal beam 100, respectively. That is, each supporting crossbeam 500 is arranged at an angle. The top surfaces of multiple support beams 500 can form an inclined surface 510 that slopes downward toward the unloading side of the frame 20. This inclined surface 510 can smoothly guide the cargo from the top of the gooseneck beam 210 to the side beam during unloading, thereby improving the smoothness of cargo unloading during side unloading, speeding up the unloading speed, and effectively preventing cargo accumulation.

[0044] Furthermore, the multiple inclined support beams 500 ensure that the unloading side of the frame 20 does not have a situation where the side corresponding to the gooseneck beam 210 is higher than the side corresponding to the main beam 220, thus allowing the side longitudinal beam 100 to be a single, straight beam, which helps to simplify the manufacturing process of the frame 20.

[0045] like Figure 4 As shown, in one embodiment, the inclination angle α of the inclined surface 510 relative to the top plane of the gooseneck beam 210 can be in the range of 5° to 15°. For example, the inclination angle α of the inclined surface 510 relative to the top plane of the gooseneck beam 210 can be 10° to achieve a smoother unloading effect.

[0046] like Figure 3 As shown, both side longitudinal beams 100 are integral straight beam structures. The two side longitudinal beams 100 are arranged parallel to each other and spaced apart along the longitudinal direction. Both end crossbeams 300 can also be straight beams. The two end crossbeams 300 are arranged parallel to each other and spaced apart along the transverse direction. One end crossbeam 300 is vertically connected between one end of the two side longitudinal beams 100, and the other end crossbeam 300 is vertically connected between the other ends of the two side longitudinal beams 100.

[0047] like Figure 3 As shown, two main longitudinal beams 200 are arranged parallel to each other along the longitudinal direction and are located between two side longitudinal beams 100. For example, the two main longitudinal beams 200 can be arranged corresponding to the two body longitudinal beams of the vehicle body 10.

[0048] like Figure 3As shown, each main longitudinal beam 200 can be fixedly connected to two end crossbeams 300 at both ends. Each main longitudinal beam 200 includes a gooseneck beam 210 and a main beam 220 connected front to back. Since the gooseneck beam 210 is set higher than the main beam 220, the end crossbeam 300 connected to the front end of the gooseneck beam 210 can be higher than the end crossbeam 300 connected to the rear end of the main beam 220.

[0049] See Figure 3 In one embodiment, the frame 20 further includes a plurality of transversely arranged main crossbeams 400. The main crossbeams 400 are spaced apart between two side longitudinal beams 100, and both ends of each main crossbeam 400 are fixedly connected to the two side longitudinal beams 100 respectively. Each main crossbeam 400 may be an integral straight beam structure. The main crossbeams 400 may be arranged in the frame area corresponding to the main beam 220, rather than in the frame area where the gooseneck beam 210 is located.

[0050] For example, such as Figure 3 As shown, each main crossbeam 400 is connected to two main beams 220 perpendicularly. Each main beam 220 can be a segmented structure to facilitate connection with the main crossbeams 400 and to ensure that the top plane of the main beam 220 is flush with the top plane of the main crossbeam 400.

[0051] like Figure 3 As shown, the top plane of each main crossbeam 400 is flush with the top plane of the main beam 220. This helps to form a flat bearing surface at the rear end of the frame 20, which in turn helps to stably support the floor of the cargo box.

[0052] See Figure 3 In one embodiment, the frame 20 is a single-sided unloading frame. That is, the frame 20 can only be flipped to one side for unloading. Specifically, as shown... Figure 4 As shown, the right side of the chassis 20 is the unloading side. The left side of the chassis 20 is the non-unloading side.

[0053] The frame 20 may also include a gooseneck side beam 600, which is longitudinally disposed on the top plane of the side longitudinal beam 100 on the left side of the frame 20. The gooseneck side beam 600 is arranged correspondingly to the gooseneck beam 210 near the left side of the frame 20. The top plane of the gooseneck side beam 600 is flush with the top plane of the gooseneck beam 210. In this embodiment, by setting the gooseneck side beam 600 and arranging it correspondingly and flush with the gooseneck beam 210, a flat bearing surface can be formed on the non-unloading side of the frame 20, thereby facilitating the unloading of all goods in the cargo box towards the unloading side.

[0054] It is understood that in other embodiments, the frame 20 may also be a double-sided unloading frame. At the same time, multiple supporting crossbeams 500 may be provided between the two gooseneck beams 210 of the frame 20 and the corresponding side longitudinal beams 100, so as to form inclined surfaces 510 on both sides of the gooseneck of the frame 20 to facilitate unloading.

[0055] See Figure 3 In one embodiment, a plurality of first wing supports 610 are provided between the gooseneck side beam 600 and the gooseneck beam 210, and each first wing support 610 is arranged laterally. One end of each first wing support 610 is fixedly connected to the gooseneck beam 210, and the other end is fixedly connected to the gooseneck side beam 600 and the corresponding side longitudinal beam 100. By providing a plurality of first wing supports 610, the gooseneck side beam 600 and the gooseneck beam 210 can be connected and supported, thereby improving the structural strength of the frame 20 and enhancing the cargo load-bearing capacity of the frame 20.

[0056] like Figure 4 As shown, the top plane of each first wing support 610 does not exceed the top plane of the gooseneck beam 210. Preferably, the top plane of each first wing support 610 is flush with the top plane of the gooseneck beam 210. This helps to form a flat bearing surface, so as to stably support the bottom plate of the cargo box and prevent the bottom plate from deforming.

[0057] See Figure 3 and Figure 4 In one embodiment, a plurality of first cross braces 211 are arranged at intervals between the two gooseneck beams 210. Each first cross brace 211 is arranged laterally, and both ends of each first cross brace 211 are fixedly connected to the two gooseneck beams 210 respectively. By setting a plurality of first cross braces 211, the two gooseneck beams 210 can be connected and supported, thereby improving the structural strength of the frame 20 and enhancing the cargo load-bearing capacity of the frame 20.

[0058] Furthermore, the top plane of each first cross brace 211 does not exceed the top plane of the gooseneck beam 210. For example, the top plane of each first cross brace 211 is flush with the top plane of the gooseneck beam 210. This helps to form a flat bearing surface, so as to stably support the bottom plate of the cargo box and prevent the bottom plate from deforming.

[0059] See Figure 3 and Figure 4In one embodiment, the semi-trailer frame 20 further includes a first reinforcing brace 213 arranged longitudinally between two gooseneck beams 210. Each first crossbeam 211 has a downwardly recessed first groove 212 on its top surface, and the first reinforcing brace 213 is fixedly installed within the first groove 212. The top surface of the first reinforcing brace 213 is flush with the top surface of the gooseneck beam 210. By providing the first reinforcing brace 213 and ensuring its top surface is flush with the top surface of the gooseneck beam 210, the support area of ​​the frame 20 can be increased to reliably support the cargo box floor and further prevent floor deformation.

[0060] It is understood that in other embodiments, when the lateral width between the gooseneck beam 210 and the side longitudinal beam 100 is large, a reinforcing brace may also be provided between the gooseneck beam 210 and the side longitudinal beam 100; or, when the lateral width between the gooseneck side beam 600 and the gooseneck beam 210 is large, a reinforcing brace may also be provided between the gooseneck side beam 600 and the gooseneck beam 210, depending on the specific circumstances.

[0061] See Figure 3 In one embodiment, a plurality of second cross braces 221 are arranged at intervals between the two main beams 220, and each second cross brace 221 is arranged laterally. The two ends of each second cross brace 221 are fixedly connected to the two main beams 220 respectively. By providing a plurality of second cross braces 221, the two main beams 220 can be connected and supported, thereby improving the structural strength of the frame 20 and enhancing the cargo load-bearing capacity of the frame 20.

[0062] The top plane of each second cross brace 221 does not exceed the top plane of the main beam 220. Preferably, the top plane of each second cross brace 221 is flush with the top plane of the main beam 220. This helps to form a flat bearing surface, so as to stably support the bottom plate of the cargo box and prevent the bottom plate from deforming.

[0063] See Figure 3 In one embodiment, multiple second wing supports 222 are provided at intervals between each main beam 220 and its corresponding side longitudinal beam 100, and each second wing support 222 is arranged laterally. One end of each second wing support 222 is fixedly connected to the main beam 220, and the other end is fixedly connected to the corresponding side longitudinal beam 100. By providing multiple second wing supports 222, the main beam 220 and the corresponding side longitudinal beam 100 can be connected and supported, thereby improving the structural strength of the frame 20 and enhancing its cargo-bearing capacity.

[0064] The top plane of each second wing support 222 does not exceed the top plane of the main beam 220. Preferably, the top plane of each second wing support 222 can be flush with the top plane of the main beam 220. This helps to form a flat bearing surface to stably support the bottom plate of the cargo box and prevent the bottom plate from deforming.

[0065] See Figure 3 In one embodiment, the semi-trailer frame 20 further includes a plurality of second reinforcing braces 225, which are arranged longitudinally between the two main beams 220 and between the main beams 220 and the corresponding side longitudinal beams 100.

[0066] Each second cross brace 221 has a downwardly recessed second groove 223 on its top surface, and each second wing brace 222 has a downwardly recessed third groove 224 on its top surface. Multiple second reinforcing braces 225 are fixedly installed in the second groove 223 and the third groove 224 respectively, and the top surface of each second reinforcing brace 225 is flush with the top surface of the main beam 220.

[0067] In this embodiment, by setting multiple second reinforcing braces 225 and making their top planes flush with the top planes of the main beam 220, the support area of ​​the frame 20 can be increased to reliably support the cargo box floor and further prevent the floor from sinking and deforming.

[0068] The side-dump semi-trailer frame and side-dump semi-trailer of this utility model adopt a gooseneck structure for both the body and frame, which effectively reduces the height of the cargo bearing surface, lowers the center of gravity of the cargo, and improves the safety of freight transportation. The frame has multiple inclined support beams on the unloading side at the gooseneck, forming an inclined surface that facilitates unloading, thereby increasing the unloading speed of the semi-trailer and preventing cargo accumulation.

[0069] The side-dump semi-trailer frame and side-dump semi-trailer of this utility model embodiment are equipped with multiple cross braces and multiple wing braces on the frame, which enhance the structural strength of the frame and can reliably support the cargo box floor. The cross braces and wing braces of the frame are also equipped with reinforcing braces, which can contact and support the cargo box floor, thereby further increasing the support area of ​​the floor and improving the floor's resistance to deformation.

[0070] The above embodiments are merely illustrative examples of structures. The structures in each embodiment are not fixed combinations. In the absence of structural conflicts, the structures in multiple embodiments can be arbitrarily combined and used.

[0071] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
