Abstract

The present invention provides a tank container, which includes a tank body, two end frames and four reinforcement components. The four reinforcement components are respectively connected to the end frames and the tank body, and jointly support the tank body. There is a longitudinal interval between the two reinforcement components arranged at both ends of the tank body, so that each reinforcement component can independently be responsible for the corresponding area of the tank body, ensuring uniform stress on the tank body and reducing the components connected between the four reinforcement components, which is beneficial to further disperse the stress of the tank body. In each reinforcement component, a reinforcement box is connected to the outer peripheral wall of the tank body, the side surface of a reinforcing ring and the end of a support beam. By means of the reinforcement box and the reinforcing ring, the stress-bearing area of the support beam on the tank body is increased, which is beneficial to dispersing stress over a large area. The reinforcement box has a cavity inside, and the width of the reinforcement box is greater than that of the support beam. The cavity of the reinforcement box further increases the area for dispersing the stress of the tank body, avoiding stress concentration in a local area of the tank body, improving the load-bearing capacity of the tank body and reducing the self-weight of the reinforcement box.

Detailed Description of the Invention

[0031] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments, all of which do not depart from the scope of the present invention, and the descriptions and illustrations therein are for illustrative purposes in nature and not intended to limit the present invention.

[0032] Referring to Figures 1 to 3 As shown, the tank container 100 provided by the embodiment of the present invention mainly includes a tank body 1, two end frames 2, and four reinforcement components 3. The two end frames 2 are relatively arranged on the outer periphery of both ends of the tank body 1 and support the tank body 1. The four reinforcement components 3 are located between the two end frames 2 and are symmetric with each other. Among them, the tank container 100 can be selected as an interchangeable tank container.

[0033] The tank body 1, as the main storage component of the tank container 100, includes a cylindrical body 11 and end heads 12 welded to both ends of the cylindrical body 11. The cylindrical body 11 and the two end heads 12 enclose a receiving cavity 13a, which is used to store the goods to be stored, and physically protect the goods to be stored, so as to realize the protection of the goods to be stored by the tank body 1.

[0034] The end frames 2 are connected to the outer peripheral wall of the tank body 1 to realize the support of the end frames 2 for the tank body 1. There are two end frames 2, and the two end frames 2 respectively support the cylindrical body 11 and are close to the corresponding end heads 12. By supporting both ends of the cylindrical body 11 through the end frames 2, the overall stability of the tank body 1 is effectively improved.

[0035] The end frames 2 can be selected to be hollow, and mainly include an end lower beam 21, an end upper beam 22, two corner posts 23, and four corner fittings 24, where the corner fittings 24 are divided into two bottom corner fittings 241 and two top corner fittings 242. Specifically, the structure of the end frames 2 adopts the structure in the related art.

[0036] The two bottom corner fittings 241 are arranged relative to the fixed positions of the vehicle frame (not shown) and are respectively arranged at both ends of the end lower beam 21. The bottom corner fittings 241 are used to connect the end lower beam 21 and the corner posts 23.

[0037] The two top corner fittings 242 correspond to the two bottom corner fittings 241 one by one. Specifically, the top corner fittings 242 and the corresponding bottom corner fittings 241 are spaced apart in the height direction. The two top corner fittings 242 are respectively arranged at both ends of the end upper beam 22. The top corner fittings 242 are used to connect the end upper beam 22 and the corner posts 23. The end lower beam 21, the end upper beam 22, and the two corner posts 23 are enclosed by the two top corner fittings 242 and the two bottom corner fittings 241, and generally form a hollow rectangle.

[0038] The four reinforcement components 3 are all connected to the end frames 2 and the tank body 1 and face the other end frame 2. Among them, the four reinforcement components 3 are symmetric with each other to ensure that the tank body 1 is evenly stressed on multiple groups of reinforcement components 3.

[0039] There is a longitudinal interval between the two reinforcing components 3 at both ends of the divided tank body 1, so that each reinforcing component 3 can independently be responsible for the corresponding area of the tank body 1, ensuring uniform stress on the tank body 1 and reducing the components connecting the four reinforcing components 3 to each other, which is beneficial to further disperse the stress of the tank body 1.

[0040] The reinforcing component 3 is mainly used for supporting the tank body 1 and realizing the reinforcement of the tank body 1 to prevent the tank body 1 from deforming due to uneven stress. Specifically, the reinforcing component 3 connects the bottom corner piece 241 and the tank body 1 and supports the tank body 1 upward.

[0041] Combined Figure 4 As shown, the reinforcing component 3 includes a reinforcing ring 31, a reinforcing box 32, a support beam 33 and an extension piece 34. The reinforcing ring 31 is fixed on the outer peripheral wall of the tank body 1, connects the reinforcing box 32 and the support beam 33, and connects the bottom corner piece 241 through the support beam 33, so that the reinforcing ring 31, the reinforcing box 32, the support beam 33, the extension piece 34 and the end frame 2 jointly support the tank body 1, reducing the load of the support beam 33 relative to the tank body 1, increasing the supporting force of the support beam 33 relative to the tank body 1, and effectively increasing the area of the support beam 33 acting on the tank body 1 through the reinforcing box 32 and the reinforcing ring 31, thereby shortening the length of the support beam 33 itself, making the support beam 33 lighter and shorter, and then realizing the lightweight structure of the tank container 100.

[0042] The reinforcing ring 31 is welded on the outer peripheral wall of the cylinder 11 and extends along the circumferential direction of the cylinder 11. Optionally, the reinforcing ring 31 is welded on a partial outer wall of the cylinder 11. The strength of the cylinder 11 is improved through the reinforcing ring 31, stress concentration of the tank body 1 is avoided, the deformation amount of the tank body 1 is reduced, and the stress area of the reinforcing component 3 acting on the tank body 1 is increased. The reinforcing ring 31 is optionally a hollow structure with a certain wall thickness, and the cross-section is rectangular. Optionally, the reinforcing ring 31 can also be processed correspondingly with the cylinder 11 and then connected to other components.

[0043] The support beam 33 is optionally in the shape of a long beam and is a hollow structure. One end of the support beam 33 is connected to the bottom corner piece 241 of the end frame 2, and the other end is obliquely connected upward to the reinforcing ring 31 and supports the cylinder 11 through the reinforcing ring 31. By connecting the end frame 2 and the reinforcing ring 31 through the support beam 33, the support strength of the reinforcing ring 31 is improved, thereby improving the support strength of the cylinder 11 and reducing the deformation amount of the cylinder 11. In addition, the stress area of the support beam 33 acting on the cylinder 11 is increased through the reinforcing ring 31, which is beneficial to large-area stress dispersion, avoiding stress concentration of the cylinder 11, and at the same time reducing the load of the support beam 33 and realizing the weight reduction of the support beam 33.

[0044] Combined again Figure 5As shown, the reinforcement box 32 is integrally formed to improve its own connection strength. The reinforcement box 32 is connected to the outer peripheral wall of the tank body 1, the side surface of the reinforcing ring 31, and the other end of the support beam 33, and is located on the side of the reinforcing ring 31 facing the middle of the tank body 1. By means of the reinforcement box 32 and the reinforcing ring 31, the stress-bearing area of the support beam 33 on the tank body 1 is increased, which is conducive to the large-area dispersion of stress.

[0045] The reinforcement box 32 includes a first connection portion 321 and two second connection portions 322. The two second connection portions 322 are connected to both sides of the first connection portion 321 and are arranged on both sides of the first connection portion 321 in the transverse direction.

[0046] The first connection portion 321 is optionally in the shape of a flat plate, and both sides of the first connection portion 321 extend beyond both sides of the support beam 33 in the transverse direction, increasing the stress dispersion area and reducing the weight of the support beam 33.

[0047] One end of the first connection portion 321 is welded to the side surface of the reinforcing ring 31. The first connection portion 321 is perpendicularly welded to the reinforcing ring 31, which is convenient for the welding process of the first connection portion 321 and the reinforcing ring 31, and improves the connection strength between the reinforcement box 32 and the reinforcing ring 31.

[0048] The first connection portion 321 is spaced opposite to the cylinder 11, and the outer surface of the first connection portion 321 is connected to one end of the support beam 33 away from the end frame 2, thereby realizing the connection between the reinforcement box 32 and the support beam 33.

[0049] Furthermore, the width of the first connection portion 321 is greater than the width of the support beam 33, so that the stress-bearing area of the reinforcement box 32 relative to the cylinder 11 is increased. The reinforcement box 32 extends beyond both sides of the support beam 33 in the transverse direction. Optionally, the middle part of the reinforcement box 32 is the connection position of the support beam 33.

[0050] The two second connection portions 322 are connected to both sides of the first connection portion 321 and are arranged on both sides of the first connection portion 321 in the transverse direction. Among them, the two second connection portions 322 extend beyond both sides of the support beam 33 in the transverse direction, increasing the stress dispersion area and reducing the weight of the support beam 33.

[0051] Both of the two second connection portions 322 are connected to the outer peripheral wall of the cylinder 11 and the first connection portion 321, so that the cross section of the reinforcement box 32 is rectangular or trapezoidal, and the second connection portion 322 disperses the stress on the cylinder 11 along its edge, increasing the stress dispersion area.

[0052] Two second connecting parts 322 and the first connecting part 321 enclose a cavity 321a, and the cavity 321a optionally extends along a direction parallel to the length direction of the first connecting part 321. The cavity 321a faces the outer peripheral wall of the cylinder 11 and is optionally rectangular. By means of the cavity 321a of the reinforcement box 32, the area for dispersing the stress of the cylinder 11 is further increased, avoiding stress concentration on the local area of the cylinder 11, improving the load-bearing capacity of the cylinder 11, and reducing the self-weight of the reinforcement box 32.

[0053] A plurality of reinforcing rib plates 323 arranged at intervals are accommodated in the cavity 321a. The reinforcing rib plates 323 are used to reinforce the reinforcement box 32 and can improve the connection strength between the reinforcement box 32 and the cylinder 11. The reinforcing rib plates 323 are optionally connected to the outer peripheral wall of the cylinder 11 and the inner wall of the reinforcement box 32. Specifically, the reinforcing rib plates 323 are connected to the cylinder 11, the first connecting part 321, and the second connecting part 322.

[0054] In another embodiment, the reinforcing rib plates 323 are externally disposed outside the cavity 321a, connecting the reinforcement box 32 and the cylinder 11, which can also reinforce the reinforcement box 32 and improve the connection strength between the reinforcement box 32 and the cylinder 11.

[0055] Furthermore, there are a plurality of reinforcement boxes 32. The plurality of reinforcement boxes 32 are connected to the reinforcing ring 31 and are arranged in an array along the extending direction of the reinforcing ring 31. By means of the plurality of reinforcement boxes 32, the stress-bearing area of the tank body 1 is increased, better avoiding stress concentration on the local area of the tank body 1. At the same time, the load of the support beam 33 is reduced, realizing the weight reduction of the support beam 33, thereby shortening the length of the support beam 33 itself, making the support beam 33 lighter and shorter, and further realizing the lightweight structure of the tank container 100.

[0056] Refer to Figure 3 and Figure 4 As shown, the extension member 34 connects the outer peripheral wall of the cylinder 11 and one end of the reinforcement box 32 away from the reinforcing ring 31, and can longitudinally extend towards the middle of the cylinder 11 and can extend along the circumferential direction of the cylinder 11. By means of the extension member 34, the stress-bearing area of the support beam 33 on the tank body 1 is further increased, and the stress on the tank body 1 is dispersed in multiple directions of the tank body 1, which is beneficial to further dispersing the stress of the tank body 1, making the tank container 100 further realize lightweight.

[0057] The extension member 34 includes a circumferentially extending plate 341 and a longitudinally extending plate 342. Both the circumferentially extending plate 341 and the longitudinally extending plate 342 are perpendicularly connected to the outer peripheral wall of the cylinder 11, and the circumferentially extending plate 341 is perpendicularly connected to the longitudinally extending plate 342.

[0058] Refer to Figure 3 and Figure 4As shown, the circumferentially extending plate 341 can optionally be in the shape of a flat plate. The circumferentially extending plate 341 connects the outer peripheral wall of the cylinder 11 and one end of the reinforcement box 32 away from the reinforcing ring 31, and extends circumferentially along the cylinder 11, further extending the force-bearing area of the cylinder 11 relative to the support beam 33, so that the reinforcement assembly 3 increases the force-bearing area of the cylinder 11. Moreover, the circumferentially extending plate 341 is conducive to increasing the area for stress dispersion in the circumferential direction of the cylinder 11, avoiding local stress concentration of the cylinder 11. In addition, it reduces the load on the support beam 33, realizes the weight reduction of the support beam 33, thereby shortening the length of the support beam 33 itself, making the support beam 33 lighter and shorter.

[0059] Optionally, the width of the circumferentially extending plate 341 is greater than the width of the reinforcement box 32, and the end face of the circumferentially extending plate 341 facing away from the cylinder 11 is flush with the end face of the reinforcement box 32 facing away from the cylinder 11.

[0060] Through the force analysis of the circumferentially extending plate 341, it is obtained that the arc length of the circumferentially extending plate 341 is 100 - 600 mm and the height is 5 - 100 mm, making the circumferentially extending plate 341 conducive to making the support beam 33 lighter and shorter, and at the same time not increasing the overall weight of the reinforcement assembly 3, thereby realizing the lightweight structure of the tank container 100.

[0061] The longitudinally extending plate 342 connects the outer peripheral wall of the cylinder 11 and the side of the circumferentially extending plate 341 facing away from the reinforcement box 32, and longitudinally extends towards the middle of the cylinder 11, so that the reinforcement assembly 3 increases the force-bearing area of the cylinder 11. Moreover, the longitudinally extending plate 342 is conducive to increasing the area for stress dispersion in the longitudinal direction of the cylinder 11, avoiding local stress concentration of the cylinder 11.

[0062] The longitudinally extending plate 342, in combination with the circumferentially extending plate 341, further extends the force-bearing area of the cylinder 11 relative to the support beam 33, so that the reinforcement assembly 3 increases the force-bearing area of the cylinder 11. Moreover, the longitudinally extending plate 342, in combination with the circumferentially extending plate 341, realizes the dispersion of stress on the cylinder 11 in multiple directions of the cylinder 11, which is conducive to further dispersing the stress of the cylinder 11.

[0063] Optionally, the height of the longitudinally extending plate 342 tapers in the direction of longitudinally extending towards the middle of the cylinder 11, facilitating the dispersion of stress in all directions. Specifically, the longitudinally extending plate 342 is triangular in shape.

[0064] There are multiple longitudinally extending plates 342. The multiple longitudinally extending plates 342 are arranged at intervals along the circumferential direction of the cylinder 11 and are symmetrically distributed on both sides of the reinforcement box 32 corresponding to the transverse direction, so that the reinforcement assembly 3 increases the force-bearing area of the cylinder 11, is conducive to further dispersing the stress of the cylinder 11, is conducive to improving the load-bearing capacity of the tank body 1, and reduces the self-weight of the reinforcement box 32. Further, the multiple longitudinally extending plates 342 are parallel to the reinforcement box 32.

[0065] As can be seen from the above technical solutions, the embodiments of the present invention have at least the following advantages and positive effects:

[0066] In the embodiments of the present invention, the four reinforcing components 3 are respectively connected to the end frames 2 and the tank body 1, and jointly support the tank body 1. There is a longitudinal interval between the two reinforcing components 3 at both ends of the tank body 1, so that each reinforcing component 3 can independently be responsible for the corresponding area of the tank body 1, ensuring uniform stress on the tank body 1 and reducing the components connected between the four reinforcing components 3, which is beneficial to further disperse the stress of the tank body 1.

[0067] In each reinforcing component 3, the reinforcing box 32 is connected to the outer peripheral wall of the tank body 1, the side surface of the reinforcing ring 31, and the end of the support beam 33. By means of the reinforcing box 32 and the reinforcing ring 31, the stress-bearing area of the support beam 33 on the tank body 1 is increased, which is beneficial to dispersing stress over a large area. The reinforcing box 32 has a cavity 321a inside, and the width of the reinforcing box 32 is greater than the width of the support beam 33. Through the cavity 321a of the reinforcing box 32, the area for further dispersing the stress of the tank body 1 is increased, avoiding stress concentration in a local area of the tank body 1, improving the load-bearing capacity of the tank body 1, and reducing the self-weight of the reinforcing box 32.

[0068] The extension member 34 is connected to the outer wall of the tank body 1 and the end of the reinforcing box 32 away from the reinforcing ring 31. The extension member 34 extends along the longitudinal and circumferential directions of the tank body 1. By means of the extension member 34, the stress-bearing area of the support beam 33 on the tank body 1 is further increased, and the stress is dispersed in multiple directions of the tank body 1, further dispersing the stress of the tank body 1, which is beneficial to improving the load-bearing capacity of the tank body 1 and reducing the self-weight of the reinforcing box 32.

[0069] Although the present invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary, rather than 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 broadly construed within the spirit and scope defined by the appended claims. Therefore, all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
