[0008] In one embodiment, along the longitudinal direction of the tank body, a portion of the outer connecting portion that extends outwardly beyond the reinforcement box relative to the other end of the reinforcement ring is arc-shaped.

[0009] In one embodiment, the diagonal bracing mechanism also includes a reinforcement box; the reinforcement box is located on the side of the reinforcement ring facing the end frame, connecting the pad, the side of the reinforcement ring and the top of the support beam, and has a cavity therein, and the reinforcement box extends along the extension direction of the support beam.

[0010] In one embodiment, the height of the reinforcement box gradually increases in a direction away from the reinforcement ring, and the bottom of the reinforcement box is in close contact with the top of the support beam.

[0026] Typical embodiments that embody 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 changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0027] When describing the orientation, the present invention takes the length direction of the tank container as the longitudinal direction and the width direction of the tank container as the transverse direction.

[0028] The present invention provides a tank container 10 , comprising a tank body 1 and a frame supported outside the tank body 1 .

[0029] See also Figure 1 The tank container 10 in this embodiment is a swap body tank container 10 (SWAPBODY). In other embodiments, the tank container 10 can also be a tank container 10 of other forms.

[0030] The tank body 1 is used to store the medium, thereby realizing the storage and transportation of the medium. The structure of the tank body 1 can refer to the relevant technology, and will not be described in detail here.

[0031] The frame is arranged outside the tank body 1 to support the tank body 1. The frame mainly includes two end frames 2 and four diagonal bracing mechanisms 3. The tank body 1 is supported by the end frames 2 and the four diagonal bracing mechanisms 3, and the stress on the tank body 1 is borne and dispersed, thereby avoiding the stress concentration phenomenon on the tank body 1, thereby reducing the risk of deformation of the tank body 1 and ensuring the safety of the tank body 1.

[0032] The two end frames 2 are arranged in parallel and spaced apart, and are respectively located at the two ends in the longitudinal direction of the tank body 1. The end frame 2 includes two corner columns 21 arranged in parallel and spaced apart, an end upper beam connected to the tops of the two corner columns 21, an end lower beam connected to the bottoms of the two corner columns 21, and two bottom corner pieces 22. The two bottom corner pieces 22 are arranged at the two ends of the end lower beam. Each bottom corner piece 22 is connected between the end lower beam and the corner column 21.

[0033] Furthermore, the end frame 2 further includes a reinforcement box 23 disposed between the bottom corner piece 22, the end lower beam and the corner column 21 to increase the strength of the end frame 2. Specifically, the cross section of the reinforcement box 23 is a right triangle, having a first right angle side and a second right angle side, wherein the first right angle side connects the end lower beam and the bottom corner piece 22, and the second right angle side connects the corner column 21. And the length of the first right angle side is greater than the length of the second right angle side.

[0034] The four diagonal bracing mechanisms 3 are respectively arranged corresponding to the bottom corners of the two end frames 2, wherein each end frame 2 includes two bottom corners, and thus the two end frames 2 include four bottom corners. The four diagonal bracing mechanisms 3 are arranged one by one corresponding to the four bottom corners, and are respectively used to disperse the stress of the four bottom corners of the tank body 1, so that the stress distribution on the tank body 1 is uniform.

[0035] In this embodiment, the diagonal bracing mechanisms 3 at both ends of the tank body 1 are longitudinally spaced and symmetrically arranged. The symmetrical arrangement here refers to the longitudinal direction of the tank container 10, and the diagonal bracing mechanisms 3 at both ends are symmetrically arranged about the longitudinal center plane of the tank body 1. The above symmetrical arrangement makes the stress distribution on the tank body 1 uniform, avoiding stress concentration on the tank body 1.

[0036] Furthermore, the diagonal bracing mechanisms 3 on both sides of the tank body 1 are symmetrically arranged with a lateral spacing, so that the stress distribution is more uniform. The symmetrical arrangement here refers to the width direction of the tank container 10, and the diagonal bracing mechanisms 3 on both sides are symmetrically arranged about the transverse center plane of the tank body 1.

[0037] Each diagonal bracing mechanism 3 includes a reinforcing ring 31, a pad 34, a transition piece 32, a support beam 33, a reinforcing box 35, a reinforcing box 36 and a reinforcing angle steel 37. The diagonal bracing mechanism 3 improves the supporting force for the tank body 1 through the cooperation of the above structures, and effectively increases the area of ​​the support beam 33 acting on the tank body 1 through the reinforcing box 35, the reinforcing box 36 and the pad 34, so that the force on the tank body 1 is uniform and dispersed, avoiding stress concentration on the tank body 1. Under the condition of the same load of the tank body 1, due to the dispersion effect of the reinforcing box 35, the reinforcing box 36 and the pad 34, the load borne by the support beam 33 is reduced, thereby reducing the length of the support beam 33, thereby reducing the weight of the tank container 10, and also facilitating the installation of some supporting systems on the side of the tank container 10 in the later stage.

[0038] Specifically, the reinforcement ring 31 is connected to the outer peripheral wall of the tank body 1 and extends along the circumference of the tank body 1. There is a longitudinal interval between the reinforcement ring 31 and the end frame 2. Specifically, the reinforcement ring 31 includes two side walls and a connecting wall connecting the two side walls, and the two side walls are located on the same side of the connecting wall. When the reinforcement ring 31 is connected to the outer peripheral wall of the tank body 1, the other end of the two side walls relative to the connecting wall is fixedly connected to the tank body 1. The reinforcement ring 31 with the above structure is provided with a cavity inside the reinforcement ring 31, which can reduce the weight of the reinforcement ring 31, thereby reducing the weight of the tank container 10.

[0039] Furthermore, the reinforcing ring 31 further includes a plurality of ribs 311 to increase the strength of the reinforcing ring 31. The plurality of ribs 311 are arranged at intervals along the circumference of the tank body 1. Each rib 311 connects the two side walls and the connecting wall.

[0040] The transition piece 32 is sleeved outside the reinforcement ring 31, and the transition piece 32 is fixedly connected to the reinforcement ring 31. In this embodiment, the transition piece 32 is located at the bottom of the tank body 1. The bottom of the tank body 1 refers to the bottom of the center line of the tank body 1 in the height direction.

[0041] Specifically, the transition piece 32 includes two side plates and a web connecting the two side plates, and the two side plates are located on the same side of the web, so that the two side plates and the web are enclosed to form a slot.

[0042] When the transition piece 32 is sleeved outside the reinforcement ring 31, the reinforcement ring 31 is clamped in the clamping groove of the transition piece 32, and the two side walls of the reinforcement ring 31 are respectively tightly attached to and fixedly connected with the two side plates of the transition piece 32, and the connecting wall of the reinforcement ring 31 is tightly attached to and fixedly connected with the web of the transition piece 32.

[0043] The length of the side of the transition piece 32 close to the corresponding end frame 2 is greater than the length of the side of the transition piece 32 close to the reinforcement box 35. Specifically, in this embodiment, the length of the transition piece 32 gradually decreases along the direction from the corresponding end frame 2 to the middle of the tank body 1. The length of the transition piece 32 refers to the length of the transition piece 32 extending along the circumferential direction of the tank body 1, and the length of the transition piece 32 is less than the length of the reinforcement ring 31.

[0044] One end of the support beam 33 is connected to the bottom corner of the end frame 2, and the other end is obliquely connected to the transition piece 32 upward. Specifically, one end of the support beam 33 is connected to the top of the bottom corner piece 22, the side of the corner column 21, and the side of the reinforcement box 23 of the end frame 2. Among them, the support beam 33 is connected to the top of the bottom corner piece 22, so the lowest end of the support beam 33 is the top of the bottom corner piece 22, which can avoid the influence of the support beam 33 on the stacking of the bottom corner piece 22.

[0045] Specifically, the cross section of the support beam 33 is in the shape of a square tube, and includes four tube walls. When the support beam 33 is connected to the bottom corner piece 22 , one of the tube walls overlaps the top of the bottom corner piece 22 .

[0046] In other embodiments, the connection position between the support beam 33 and the end frame 2 can be further moved upward, that is, the support beam 33 is not connected to the bottom angle piece 22, but is only connected and fixed to the corner column 21.

[0047] The other end of the support beam 33 has a bayonet, which is clamped and fixedly connected with the transition piece 32. Specifically, the bayonet has two side walls, one side wall is attached to and fixedly connected with the side plate of the transition piece 32, and the other side wall is attached to and fixedly connected with the web of the transition piece 32.

[0048] Specifically, the width of the support beam 33 is smaller than the length of the transition piece 32, so that the stress on the support beam 33 is fully dispersed to the transition piece 32, avoiding stress concentration. The width of the support beam 33 refers to the dimension of the support beam 33 along the radial direction of the tank body 1. That is, the transition piece 32 is added at the connection between the support beam 33 and the reinforcement ring 31 to protect the reinforcement ring 31 at the main stress point of the reinforcement ring 31.

[0049] The reinforcing angle steel 37 is arranged between the support beam 33 and the bottom angle piece 22. The reinforcing angle steel 37 has two mutually perpendicular side parts, the two side parts are attached to the outside of two tube walls of the support beam 33, and the side parts are fixedly connected to the tube walls. Specifically, one side part is attached to the bottom of the support beam 33, and the other side part is attached to the inner side of the support beam 33. Among them, along the width direction of the tank body 1, the direction in which the two corner columns 21 of the end frame 2 face each other is the inner side, and the direction in which the two corner columns 21 are separated is the outer side.

[0050] The backing plate 34 is connected to the outer peripheral wall of the tank body 1 and is located between the outer peripheral wall of the tank body 1 and the reinforcement ring 31 . The backing plate 34 extends in the longitudinal direction of the tank body 1 .

[0051] The backing plate 34 includes an inner connecting portion 341 and an outer connecting portion 342 arranged on both sides of the reinforcing ring 31 along the longitudinal direction, and a transition portion connecting the inner connecting portion 341 and the outer connecting portion 342, and the outer connecting portion 342 faces the middle side of the tank body 1. In this embodiment, the backing plate 34 is an integrally formed structure, so that the backing plate 34 has greater strength.

[0052] The transition portion is located between the tank body 1 and the reinforcement ring 31 .

[0053] The width of the outer connection portion 342 gradually increases in the direction away from the reinforcement ring 31. Therefore, when the tank container 10 is impacted, the stress on the support beam 33 is transmitted to the pad 34 through the reinforcement ring 31, and the pad 34 is further transmitted to the tank body 1. The width of the outer connection portion 342 of the pad 34 gradually increases, so that when the stress on the outer connection portion 342 is dispersed in the longitudinal direction, the stress on the pad 34 gradually decays.

[0054] The ends of the outer connecting portion 342 are all arc-shaped, so that the transition between the outer connecting portion 342 and the tank body 1 is an arc-shaped transition, thereby avoiding stress concentration. Furthermore, the end of the outer connecting portion 342 away from the reinforcement ring 31 is arc-shaped.

[0055] The width of the end of the outer connecting portion 342 close to the reinforcement ring 31 is smaller than the length of the transition piece 32 close to the outer connecting portion 342, ensuring that the stress on the transition piece 32 can be fully transferred to the pad 34. In other embodiments, the width of the end of the outer connecting portion 342 close to the reinforcement ring 31 can also be the same as the length of the transition piece 32 close to the outer connecting portion 342.

[0056] Two mounting holes spaced apart in the longitudinal direction are provided on the outer connection portion 342. The provision of the two mounting holes facilitates the fixed connection between the backing plate 34 and the tank body 1, and ensures the connection strength between the backing plate 34 and the tank body 1. In this embodiment, the backing plate 34 is welded to the tank body 1, and the tank body 1 and the backing plate 34 are also welded and fixed around the mounting holes.

[0057] The width of the transition portion gradually decreases along the extending direction of the outer connecting portion 342 toward the inner connecting portion 341 .

[0058] The width of the inner connection part 341 at the end close to the reinforcement ring 31 is smaller than the length of the transition piece 32 close to the inner connection part 341, which ensures the transmission of stress. The extension direction of the inner connection part 341 away from the reinforcement ring 31 is the same as the extension direction of the support beam 33 away from the reinforcement ring 31, that is, the inner connection part 341 is located directly below the support beam 33.

[0059] The ends of the outer and inner connecting parts 341 are both arc-shaped transitions, so that the transition between the inner connecting part 341 and the tank body 1 is an arc-shaped transition, thereby avoiding stress concentration.

[0060] The reinforcement box 35 is located on one side of the reinforcement ring 31 toward the middle of the tank body 1, and connects the pad 34, the side of the transition piece 32 and the end of the support beam 33. The reinforcement box 35 has a cavity therein to reduce the deadweight of the reinforcement box 35.

[0061] Specifically, the width of the reinforcement box 35 gradually increases in the direction away from the reinforcement ring 31, and the width of the end of the reinforcement box 35 close to the reinforcement ring 31 is greater than the width of the support beam 33, so that when the stress on the support beam 33 is transferred to the reinforcement box 35, the stress on the reinforcement box 35 is gradually dispersed and gradually attenuated as the width gradually increases.

[0062] The width of the reinforcement box 35 is smaller than that of the pad 34 , that is, both sides of the pad 34 extend beyond the reinforcement box 35 , so that the stress on the reinforcement box 35 is transferred to the pad 34 , thereby preventing the stress on the reinforcement box 35 from being directly transferred to the tank body 1 .

[0063] The width of the reinforcement box 35 is greater than the width of the support beam 33, that is, both sides of the reinforcement box 35 extend beyond the support beam 33 in the transverse direction, so that the stress on the support beam 33 is dispersed to the reinforcement box 35, reducing local stress.

[0064] When the reinforcement box 35 is connected to the backing plate 34, the reinforcement box 35 covers the two mounting holes on the backing plate 34. The end of the reinforcement box 35 is also fixedly connected to the reinforcement ring 31, further strengthening the connection stability and connection strength between the tank body 1 and the backing plate 34.

[0065] After the reinforcement box 35 is connected to the pad 34, the arc of the other end of the pad 34 away from the reinforcement ring 31 is exposed to the outside, that is, the reinforcement box 35 does not cover the arc of the pad 34, so that after the stress on the reinforcement box 35 is transferred to the pad 34, the arc design on the pad 34 can avoid stress concentration.

[0066] Specifically, the reinforcement box 35 itself is a symmetrical structure, so the stress is symmetrically dispersed on the pad 34. In this embodiment, the cross section of the reinforcement box 35 is an isosceles trapezoid.

[0067] Furthermore, the height of the reinforcement box 35 gradually decreases in the direction away from the reinforcement ring 31, and the reinforcement box 35 is fixedly connected to the top of the end of the support beam 33 near the reinforcement ring 31, so that when the stress on the support beam 33 is transferred to the reinforcement box 35, the stress on the reinforcement box 35 is gradually transferred to the pad 34 along the height direction.

[0068] The reinforcement box 36 is disposed on the other side of the reinforcement ring 31 relative to the reinforcement box 35. The reinforcement box 36 has a cavity therein, which reduces the dead weight of the reinforcement box 36 and further reduces the weight of the tank container 10.

[0069] The reinforcement box 36 is located on the side of the reinforcement ring 31 facing the end frame 2, and extends along the extension direction of the support beam 33. The reinforcement box 36 connects the inner connection portion 341 of the pad 34, the side of the transition piece 32 and the top of the support beam 33. Specifically, the height of the reinforcement box 36 gradually increases in the direction away from the reinforcement ring 31, so that the bottom of the reinforcement box 36 abuts against and is fixedly connected to the top of the support beam 33. In this embodiment, the cross section of the reinforcement box 36 is rectangular.

[0070] Through the reinforcement box 35 and the reinforcement box 36 respectively located on both sides of the reinforcement ring 31, the stress on the support beam 33 can be transmitted and dispersed to the entire pad 34, and the structure of the reinforcement box 35, the reinforcement box 36 and the pad 34 increases the force-bearing area between the support beam 33 and the tank body 1, so that the stress is gradually attenuated, and the stress transmitted to the tank body 1 is uniform and small. Therefore, the diagonal bracing mechanism 3 in the present invention can avoid stress concentration on the tank body 1 and better protect the tank body 1.

[0071] In this embodiment, the reinforcing rings 31 of the two diagonal bracing mechanisms 3 at the same end of the tank body 1 are located on the same arc and connected as a whole. The reinforcing rings 31 of the two diagonal bracing mechanisms 3 at the same end of the tank body 1 can also be arranged around the outer circumference of the tank body 1 for a full circle, according to actual conditions. And a reinforcing ring 31 can also be arranged between the reinforcing rings 31 at both ends of the tank body 1 to increase the support for the tank body 1.

[0072] Further, the ratio of the longitudinal distance D between the connection point of the support beam 33 and the tank body 1 and the corresponding end frame 2 to the longitudinal distance L between the two end frames 2 is 0.2 to 0.4. Specifically, the longitudinal distance L refers to the distance between the outer side surfaces of the bottom corner pieces 22 of the two end frames 2. The longitudinal distance D refers to the distance between the center of the reinforcement ring 31 and the outer side surface of the bottom corner piece 22 corresponding to the reinforcement ring 31.

[0073] That is, the position of the diagonal bracing mechanism 3 in the present invention is closer to the end of the tank body 1 , thereby increasing the middle space of the tank container 10 and facilitating the installation of the supporting system on the tank container 10 .

[0074] Furthermore, the central angle of the arc between the connection point m between the support beam 33 and the tank body 1 and the transverse center plane of the tank body 1 is 10° to 50°, that is, the central angle of the arc between the connection points where the two support beams 33 located at the same end of the tank body 1 are respectively connected to the tank body 1 is 20° to 100°.

[0075] That is, the position of the diagonal bracing mechanism 3 in the present invention is closer to the bottom of the tank body 1, that is, along the height direction of the tank body 1, the connection point between the diagonal bracing mechanism 3 and the tank body 1 is closer to the bottom, and the support beam 33 is tilted along this angle, which reduces the direct impact of the support pipe on the tank body 1. The support beam 33 is connected to the top of the bottom angle piece 22, and the angle setting of the support beam 33 is coordinated to prevent the position of the entire diagonal bracing mechanism 3 from being too low, thereby avoiding the risk of collision with the vehicle frame.

[0076] It can be seen from the above technical solutions that the embodiments of the present invention have at least the following advantages and positive effects:

[0077] The tank container in the present invention includes a tank body and a frame. The frame includes two end frames and four diagonal bracing mechanisms, and each diagonal bracing mechanism includes a reinforcing ring, a pad, a support beam and a reinforcing box. The width of the reinforcing box gradually increases in the direction away from the reinforcing ring, so that the stress on the support beam gradually decays, thereby reducing the stress on the tank body. The width of the reinforcing box is smaller than the width of the pad and the pad is exposed, so that the stress on the reinforcing box is transferred to the pad, and then the pad is transferred to the tank body, further reducing the stress reaching the tank body. The reinforcing box and the pad are used to effectively increase the area of ​​the support beam acting on the tank body, so that the force on the tank body is uniform and dispersed, avoiding stress concentration on the tank body. Under the condition of the same tank body load, due to the dispersing effect of the reinforcing box and the pad, the load borne by the support beam is reduced, and then the length of the support beam can be reduced, so that the weight of the tank container can be reduced, and it is also convenient to install some supporting systems on the side of the tank container in the later stage.

[0078] The tank container evenly disperses the stress on the tank body through the four diagonal bracing mechanisms, thereby avoiding stress concentration on the tank body, thereby reducing the risk of tank body deformation and improving the bearing capacity of the tank body.

[0079] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in a variety of 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, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
