Description

Technical Field

[0001] The utility model relates to the technical field of semitrailer manufacturing, and more specifically, to an aluminum alloy beam of a container transport semitrailer. Background Art

[0002] Container transport semi-trailer is a kind of transportation vehicle specially used for transporting various containers. It is widely used because it can load and unload goods by quick disassembly. The aluminum alloy beam of the semi-trailer is also called the longitudinal beam, which is an important component used for carrying in the container transport semi-trailer.

[0003] The beam is usually composed of a front section, a gooseneck section and a rear section, and each section is connected and reinforced by welding. In the traditional beam structure, welding is required from the front to the rear of the beam to fix each section. The welding range is large, the welding workload is large, and it is easy to cause many welds and affect the appearance; and because the welding temperature is high, it is easy to cause structural defects and deformation at the welding position, thereby reducing the service life of the beam. In order to increase the service life of the beam, the existing technology increases the strength of the gooseneck part of the beam by adding reinforcing ribs and reinforcing plates to the gooseneck part, thereby achieving the effect of increasing the service life of the beam.

[0004] In order to increase the service life of the beam, a semi-trailer beam is disclosed in a patent application with authorization announcement number CN209051496U. The purpose of strengthening the strength of the gooseneck is achieved by adding a first channel steel on the gooseneck and adding reinforcement plates on both sides of the web. However, although such a beam structure can improve the strength of the gooseneck part, it cannot reduce the welding range between the gooseneck part and the front part and the rear part, resulting in that the welding workload has not been reduced, and the structural defects and deformation problems caused by welding have not been effectively solved.

[0005] Therefore, there is an urgent need for an aluminum alloy beam for a container transport semitrailer that can reduce the welding workload. Utility Model Content

[0006] An object of the present invention is to solve at least the above-mentioned disadvantages and to provide at least the advantages to be described below.

[0007] Another object of the utility model is to provide an aluminum alloy beam for a container transport semitrailer, which optimizes the gooseneck structure, reduces the welding range, and thus reduces the welds, so that the processed aluminum alloy beam is more beautiful.

[0008] In order to achieve these purposes and other advantages of the utility model, the utility model provides an aluminum alloy beam for a container transport semitrailer, comprising: a front section structure, a gooseneck structure and a rear section structure.

[0009] The front section structure is an I-beam aluminum structure, including a front section upper wing panel, a front section middle belly and a front section lower wing panel.

[0010] The rear section structure is an I-beam aluminum structure, including a rear section upper wing panel, a rear section middle belly and a rear section lower wing panel.

[0011] A gooseneck structure, comprising a gooseneck upper wing plate structure and a gooseneck lower wing plate structure; the gooseneck upper wing plate structure comprises a front end portion of an upper wing plate, an arc-shaped portion of an upper wing plate and a rear end portion of an upper wing plate connected in sequence; the top surface of the front end portion of the upper wing plate abuts against the bottom surface of the front upper wing plate, and the bottom surface of the rear end portion of the upper wing plate abuts against the top surface of the rear end upper wing plate; the gooseneck lower wing plate structure comprises a front end portion of a lower wing plate, an arc-shaped portion of a lower wing plate and a rear end portion of a lower wing plate connected in sequence; the top surface of the front end portion of the lower wing plate abuts against the bottom surface of the front lower wing plate, and the top surface of the rear end portion of the lower wing plate abuts against the top surface of the rear end lower wing plate.

[0012] In the above scheme, specifically, the front section structure and the rear section structure are both integrally formed structures. By optimizing the gooseneck structure, it is convenient to connect the front section structure and the rear section structure through the optimized gooseneck structure, and the connection length of the gooseneck structure with the front section structure and the rear section structure is reduced, thereby reducing the range required for welding, which can not only reduce the welding workload, but also reduce the welds, making the processed aluminum alloy beam more beautiful.

[0013] Secondly, the gooseneck structure is used to reduce the welding range, thereby reducing the structural defects and deformation caused by welding, and improving the reliability of the aluminum alloy beam of the container transport semi-trailer.

[0014] In addition, by connecting the gooseneck structure to reduce the welding range, carbon emissions can be effectively reduced, which is more environmentally friendly than traditional beam processing methods.

[0015] Preferably, the bottom surface of the front lower wing plate is further provided with a concave groove, and the groove is located in the middle of the front lower wing plate.

[0016] Preferably, the middle abdomen of the front section is a hollow box-shaped structure.

[0017] In the above scheme, the middle belly of the front section is a hollow structure, which can reduce the weight of the middle belly of the front section, and then reduce the weight of the front section structure, further reducing the weight of the aluminum alloy beam of the container transport semi-trailer, so that the aluminum alloy beam of the container transport semi-trailer obtains a larger cargo weight; secondly, since the middle belly of the front section is a hollow structure, the materials used in the manufacture of the middle belly of the front section are reduced, thereby reducing the processing cost of the aluminum alloy beam of the container transport semi-trailer.

[0018] Preferably, at least one transverse rib is further provided in the middle portion of the middle abdomen of the front section.

[0019] In the above scheme, by adding transverse reinforcement in the middle of the middle belly of the front section, the bearing capacity of the front section structure is increased, thereby increasing the bearing capacity of the aluminum alloy beam of the container transport semitrailer.

[0020] Preferably, the length of the front end portion of the upper wing plate is at least 150 mm; and the curvature of the arc-shaped portion of the upper wing plate is 40° to 50°.

[0021] In the above scheme, the length and curvature of the upper wing plate structure are adjusted to reduce the length of the upper wing plate structure as much as possible while ensuring that the gooseneck structure stably connects the front section structure and the rear section structure, thereby reducing the welding range between the upper wing plate structure and the front section and the rear end section.

[0022] Preferably, the front end of the lower wing plate is connected to the traction pin plate of the front section structure; the rear end of the lower wing plate is connected to the suspension force point of the rear section structure; and the curvature of the arc-shaped portion of the lower wing plate is greater than the turning radius of the tractor.

[0023] Advantages of the utility model:

[0024] Firstly, the front section structure and the rear section structure of the aluminum alloy beam of the container transport semi-trailer of the utility model are both integrally formed structures. By optimizing the gooseneck structure, it is convenient to connect the front section structure and the rear section structure through the optimized gooseneck structure, and the connection length of the gooseneck structure with the front section structure and the rear section structure is reduced, thereby reducing the range required for welding, which can not only reduce the welding workload, but also reduce the welds, making the processed aluminum alloy beam more beautiful.

[0025] Secondly, the aluminum alloy beam of the container transport semi-trailer of the utility model is connected by a gooseneck structure to reduce the welding range, thereby avoiding structural defects and deformation problems caused by welding, and improving the reliability of the aluminum alloy beam of the container transport semi-trailer.

[0026] In addition, the aluminum alloy beam of the container transport semi-trailer of the utility model is connected by a gooseneck structure to reduce the welding range, which can effectively reduce carbon emissions and is more environmentally friendly than traditional beam processing methods.

[0027] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through research and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
