Description

Technical Field

[0001] The utility model relates to the technical field of trailer frame processing, in particular to a skeleton vehicle frame chassis with a cargo platform. Background Art

[0002] Skeleton trucks are mainly used for the transportation of containers. They mainly include two longitudinally parallel main beams and connecting crossbeams, end beams and through-beams arranged between the two main beams. Since skeleton trucks are mainly composed of the main beams and their attached structures, their weight is lighter than that of other fully loaded flatbed trucks, which can save a lot of transportation costs during transportation. Therefore, skeleton trucks are currently widely used in more than 40 types of trailer models. When they are not involved in the transportation of loaded containers, they can also be used to carry small vehicles such as forklifts. Therefore, a loading platform will be added to the rear end of the existing skeleton truck. The existing loading platform is mostly an integrated structure, which is mainly fixed to the frame by welding and is always fixed. This will increase its own weight and reduce the transportation efficiency of the container, which is not worth the loss. Utility Model Content

[0025] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, with the normal traveling direction of the skeleton vehicle being the front and the other side opposite to the front being the rear.

[0026] like Figures 1 to 4 As shown, a skeleton vehicle frame chassis with a cargo platform includes a left longitudinal beam 1, a right longitudinal beam 2 and a plurality of intermediate cross beams 3 connecting and fixing the left and right longitudinal beams. The front end of the frame body is provided with a gooseneck for traction connection, wherein the left longitudinal beam 1 and the right longitudinal beam 2 have the same structure and are arranged in parallel and symmetrically, and together form the skeleton vehicle frame body; at the same time, the frame body is also fixedly installed with a front end beam 4, a middle front cantilever beam 5, a middle cantilever beam 6, a middle rear cantilever beam 7 and a rear end beam 8 in sequence from front to back. The composition of the skeleton vehicle frame body structure here can be set according to actual production needs with reference to the relevant technical features in the prior art, and will not be repeated here. The cargo platform 9 is arranged between the rear end beam 8 and the rear center cantilever beam 7 of the frame body, and includes a fixed platform plate 91, a detachable platform plate 92 and corresponding brackets. The fixed platform plate 91 and its corresponding fixed bracket 93 are arranged between the left and right longitudinal beams in the frame body, and the detachable platform plate 92 and its corresponding detachable bracket 94 are provided in two groups with the same structure, which are symmetrically installed to the outer sides of the left longitudinal beam 1 and the right longitudinal beam 2 in the frame body.

[0027] The fixed bracket 93 is composed of a central crossbeam 931 and multiple central vertical beams 932 fixed together in a horizontal and vertical manner to form a frame structure. The multiple central vertical beams 932 are parallel to each other and fixed at equal intervals. Their ends are fixed to the inner side walls of the web plates of the left and right longitudinal beams by fastening bolts. The central crossbeam 931 is positioned at the center point of the central vertical beam 932 and fixed perpendicularly to the central vertical beam 932, with their upper end surfaces flush. The ends of the central crossbeam 931 are fixed to the rear side walls of the central rear cantilever beam 7 and the front side walls of the rear end beam 8 by fastening bolts, respectively. The fixed platform plate 91 is a flat plate structure, placed above the fixed bracket 93 and welded to it. The upper end surface of the fixed platform plate 91 is placed on the bottom surface of the central upper wing plates of the left and right longitudinal beams and is flush with the top surfaces of the central rear cantilever beam 7 and the rear end beam 8.

[0028] According to a further optimized technical solution, the above-mentioned middle vertical beam 932 can be divided into two, and the two ends of each section of the middle vertical beam 932 are respectively fixedly connected to the longitudinal beam web and the middle cross beam 931 on the corresponding side, and the connection and fixing method can also be directly welded.

[0029] Combine Figures 5 to 7 As shown, the detachable bracket 94 also includes a supporting crossbeam 941 and multiple supporting vertical beams 942. The multiple supporting vertical beams 942 are parallel to each other and arranged at equal intervals. At the same time, they are fixed vertically and horizontally relative to the supporting crossbeam 941. The installation position of the supporting crossbeam 941 is offset to the end side of the supporting vertical beam 942 close to the longitudinal beam, so as to change its center of gravity position and improve the stability of the connection. The detachable platform plate 92 is a shell with an inverted U-shaped cross section and an open lower end. It is covered and fixed on the upper outer side of the above-mentioned detachable bracket 94 and welded to form an integrated structure. The front and rear ends of the detachable platform plate 92 are respectively fixed with end beams 921. The cross section of the end beam 921 is a horizontal U-shaped, and its top surface is tightly attached to the bottom surface of the top plate of the detachable platform plate 92. The outer end surface of the end beam 921 is flush with the end surface of the detachable platform plate 92, forming a blockage.

[0030] Several groups of coaxial connecting holes 943 and 922 are provided on the inner vertical walls of the above-mentioned supporting crossbeam 941 and the detachable platform plate 92. Correspondingly, the same number of connecting screw holes are provided on the webs of the left longitudinal beam 1 and the right longitudinal beam 2 respectively. The detachable platform plate 92 and its corresponding detachable bracket 94 are connected to the longitudinal beam on the same side by means of bolts passing through the connecting holes and connecting screw holes on the corresponding sides.

[0031] Furthermore, support brackets 10 are fixedly mounted on the rear sidewalls of the center-rear cantilever beam 7 and the front sidewalls of the rear end beam 8, respectively, via bolts and nuts. The support brackets 10 have an inverted L-shaped cross-section, with the front and rear support brackets 10 symmetrical and flush with each other. The upper horizontal plates of the support brackets 10 are provided with multiple connecting holes; correspondingly, the lower horizontal plates of the end beams 921 are provided with multiple bolt holes. The removable platform plate 92 with removable brackets 94 is placed on the two support brackets 10 and then removably connected via bolts passing through the corresponding bolt holes and connecting holes, enabling installation and removal of the removable platform plate 92. In the installed state, the upper end surface of the removable platform plate 92 is flush with the top surfaces of the center-rear cantilever beam 7 and the rear end beam 8.

[0032] As a further optimized technical solution of the present invention, the end plates at both ends of the above-mentioned middle and rear cantilever beam 7 and the rear end beam 8 are extended outward to form positioning plates. When the detachable platform plate 92 is installed, the outer end surface of the detachable platform plate 92 is attached to the inner side surface of the positioning plate, completing the determination of the installation position of the detachable platform plate 92 and preventing the detachable platform plate 92 from being offset and tilted during installation.

[0033] At the same time, an inclined support frame 11 is provided on the outer side wall of the web in the left longitudinal beam 1 and the right longitudinal beam 2. The top of the inclined support frame 11 is provided with an integrally formed support platform, which can support the bottom of the support beam 941 in the detachable bracket 94, thereby increasing the stability of the detachable platform plate 92 after installation.

[0034] As a further optimized technical solution, the supporting vertical beam 942 is provided with a plurality of circular holes arranged at intervals to reduce its own counterweight, achieve a lightweight setting, and facilitate disassembly and installation.

[0035] The fixed platform plate 91 and the detachable platform plate 92 are both made of steel plates.

[0036] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
