Description

Technical Field

[0001] This utility model belongs to the field of storage and transportation cargo box technology, and in particular relates to a cargo box chassis. Background Technology

[0002] Storage and transportation containers are used to transport goods, thus requiring the container chassis to have sufficient strength and rigidity. Existing container chassis are welded from structural steel and steel plates, which, while meeting the performance requirements, result in excessive overall weight. This leads to a smaller cargo capacity when the load requirement is fixed, increasing transportation costs. Container manufacturers are constantly seeking ways to reduce the weight of container chassis; designing lightweight container chassis has long been a challenging technical problem for those skilled in the art.

[0003] In addition, mudguards are installed on the cargo box chassis. Existing mudguards are all fixed to the cargo box chassis. However, due to the slight difference in the wheelbase of trucks, the front and rear spacing of the mudguards also varies. Therefore, it is difficult to standardize the cargo box chassis during the manufacturing process, which is not conducive to mass production and leads to increased production costs.

[0004] Therefore, in the field of storage and transportation cargo box technology, there is still a need for research and improvement of cargo box chassis. This is a current research hotspot and focus in the field of storage and transportation cargo box technology, and it is also the starting point for the completion of this utility model. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to provide a cargo box chassis to solve the technical problem that the cargo box chassis is heavy and not conducive to mass production.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a cargo box chassis, including a chassis body, on which a mudguard is installed. The chassis body includes several bent keel plates fixed together in sequence. Each bent keel plate is composed of a bending plate, a bottom plate, and a bending groove. The bending plate has a connecting part perpendicular to the surface of the bottom plate and a bending part parallel to the surface of the bottom plate. The bending groove is consistent with the bending direction of the bending plate and has an L-shaped receiving groove for accommodating the bending part. The length of the bottom of the L-shaped receiving groove from the surface of the bottom plate is the same as the length of the bottom surface of the bending part from the surface of the bottom plate.

[0007] As an improvement, the surface of the base plate is provided with reinforcing ribs, and the cross-sectional shape of the reinforcing ribs is U-shaped.

[0008] As a further improvement, the reinforcing rib is provided with mounting plates arranged opposite each other. A front connecting plate and a rear connecting plate are installed between the two opposite mounting plates by fasteners. A support plate is installed on the rear connecting plate by fasteners. One end of the mudguard is installed on the front connecting plate by fasteners, and the other end is connected to the support plate by fasteners.

[0009] As a further improvement, the mounting plate has a plurality of horizontally spaced mounting holes at one end corresponding to the front connecting plate, and a horizontally extending mounting groove at one end corresponding to the rear connecting plate.

[0010] After adopting the above technical solution, the beneficial effects of this utility model are:

[0011] The cargo box chassis provided by this utility model has a bent plate and a bent groove formed on the bottom plate to form a lightweight keel structure. This not only improves the rigidity and strength of the plate and reduces the overall weight of the cargo box chassis, but also facilitates production and construction, enables mass production, and thus reduces production costs.

[0012] Because the mounting plate has mounting holes and mounting slots, the front connecting plate can be installed on different mounting holes. Correspondingly, the fasteners of the rear connecting plate slide to the appropriate position in the mounting slot, and after adjustment, the fasteners in the mounting slot are tightened to fix the mudguard in that position, thereby changing the axial position of the mudguard to meet the needs of trucks with different wheelbases.

[0021] like Figure 1 As shown, this utility model embodiment provides a cargo box chassis, including a chassis body, a mudguard 7 installed on the chassis body, and the chassis body including a plurality of bent keel plates 1 fixed together in sequence, as shown. Figure 2As shown, the bent keel plate 1 consists of a bent plate, a base plate 101, and a bending groove. The bent plate, base plate 101, and bending groove are integrally formed. During manufacturing, the bent plate, base plate 101, and bending groove are formed by bending steel plates. The bent plate has a connecting part 102 perpendicular to the surface of the base plate 101 and a bending part 103 parallel to the surface of the base plate 101. The connecting part 102 and the base plate 101, as well as the connecting part 102 and the bending part 103, are both at right angles. The bending groove is in the same bending direction as the bent plate. The bending groove has an L-shaped receiving groove 104 to accommodate the bent portion 103. During manufacturing, several bent keel plates 1 are placed sequentially into the L-shaped receiving groove 104 with their bent portions 103, and then welded together. The length of the bottom of the L-shaped receiving groove 104 from the surface of the base plate 101 is the same as the length of the bottom surface of the bent portion 103 from the surface of the base plate 101, ensuring that the base plates 101 of all welded bent keel plates 1 remain on the same plane, simplifying the processing technology and facilitating construction. This structure bends and forms a bent plate and bending groove on the base plate 101, creating a lightweight keel structure. This not only improves the rigidity and strength of the plate and reduces the overall weight of the cargo box chassis, but also facilitates production and construction, enabling mass production and thus reducing production costs.

[0022] The surface of the base plate 101 is provided with reinforcing ribs 2. The cross-sectional shape of the reinforcing ribs 2 is U-shaped. The open side of the reinforcing ribs 2 faces the base plate 101. After the reinforcing ribs 2 are combined with the surface of the base plate 101, they form a closed U-shaped structure, which increases the rigidity and strength of the base plate 101.

[0023] The reinforcing rib 2 is provided with a mounting plate 3 that is positioned opposite to it. The extending direction of the mounting plate 3 is perpendicular to the extending direction of the reinforcing rib 2. Figure 3 As shown, a front connecting plate 5 and a rear connecting plate 4 are fastened together between two opposing mounting plates 3. A support plate 6 is fastened to the rear connecting plate 4. One end of the mudguard 7 is fastened to the front connecting plate 5, and the other end is fastened to the support plate 6. This structure of the mudguard 7, which is connected by fasteners, facilitates the installation and removal of the mudguard 7. It also facilitates the mass production of the chassis and the mudguard 7 separately, and then the assembly as needed.

[0024] The mounting plate 3 has several horizontally spaced mounting holes 301 at one end corresponding to the front connecting plate 5, and a horizontally extending mounting groove 302 at one end corresponding to the rear connecting plate 4. The front connecting plate 5 can be installed on different mounting holes 301. Correspondingly, the fasteners of the rear connecting plate 4 slide to the appropriate position in the mounting groove 302, and after adjustment, the fasteners in the mounting groove 302 are tightened to fix the mudguard 7 in this position, thereby changing the axial position of the mudguard 7 to meet the needs of trucks with different wheelbases.

[0025] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
