DETAILED DESCRIPTION

[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] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0028] Example 1

[0029] See also Figure 1 This embodiment provides a standard tank container (ISO) 1, including a tank body 12, a frame supporting the tank body 12, a connecting member 13 and a covering member 14.

[0030] The tank body 12 is arranged in the frame, and its two ends are longitudinally limited by the two end frames 111 of the frame. The material of the tank body 12 is a non-metal composite material, which can store and transport some media that cannot be stored and transported by existing metal tanks, such as highly corrosive acids, etc., and the non-metal composite material has a low density and light weight, which can increase the effective load and improve efficiency.

[0031] The overall structural shape of the tank body 12 in this embodiment is roughly the same as the shape of the existing tank body, the main part is roughly cylindrical, and the shapes of the two ends are the same as the head form of the existing tank body. For ease of description, the main part and the two end parts of the tank body 12 are respectively called the cylinder 121 and the head 122 using the names of the prior art. However, it is emphasized again that the material of the tank body 12 in this embodiment is a non-metallic composite material, so there is no joint seam between an ordinary cylinder and a head. It can be understood that in this embodiment, the tank body 12 is divided into the cylinder 121 and the head 122, which is mainly a distinction made based on their shapes and positions, and does not represent the actual composition structure of the tank body 12.

[0032] Preferably, the outer wall of the tank body 12 is provided with a reinforcing flange 123 protruding along the circumferential direction. Specifically, the reinforcing flange 123 is provided on the cylinder 121 of the tank body 12. In this embodiment, the reinforcing flange 123 is integrally formed on the cylinder 121, which not only improves the pressure-bearing capacity of the tank body 12, but also improves the connection strength between the tank body 12 and the frame. In other embodiments, the reinforcing flange 123 can also be fixed to the cylinder 121 of the tank body 12 by bonding, fusing, etc.

[0033] Furthermore, the cross-sectional shape of the reinforcing flange 123 may be semicircular, trapezoidal or other shapes, which may be set according to actual needs.

[0034] See also Figure 1 The frame includes two end frames 111 spaced apart and diagonal braces 112 connected to the end frames 111 and extending toward the tank body 12. Specifically, the end frame 111 includes two corner columns 1111, an upper end beam, a lower end beam, and corner pieces 1114 connecting the two corner columns 1111. The diagonal braces 112 are connected to each corner piece 1114, that is, each end frame 111 is connected to four diagonal braces 112.

[0035] Preferably, a side brace 113 is further provided between the diagonal brace 112 and the corresponding corner column 1111 to improve the connection strength of the diagonal brace 112 .

[0036] Re-read Figure 1 In this embodiment, two reinforcing convex edges 123 are arranged at intervals along the length direction of the tank body 12. Four force points are arranged at intervals along the outer circumference direction of the tank body 12, respectively corresponding to the four diagonal braces 112 of each end frame 111, and each connecting member 13 is arranged in a one-to-one correspondence with each diagonal brace 112. In other embodiments, the connecting member 13 can also be arranged around the outer circumference of the tank body 12.

[0037] See also Figure 2The connecting member 13 is an integrally formed structure, including a frame connecting portion 131 and a tank body connecting portion 132. Specifically, the material of the connecting member 13 is metal. In this embodiment, the frame connecting portion 131 is U-shaped, and the opening of the U-shaped portion is bent and extended outward to form two extension portions, which constitute the tank body connecting portion 132, and the reinforcing flange 123 is arranged in the U-shaped space. In other embodiments, the structure of the connecting member 13 can also be set according to actual needs.

[0038] The frame connection part 131 is welded to the diagonal brace 112, thereby realizing the connection between the frame and the connecting member 13. Preferably, along the radial direction of the tank body 12, there is a gap between the frame connection part 131 and the reinforcing flange 123, thereby avoiding the thermal effect of welding heat on the reinforcing flange 123 when the frame connection part 131 and the diagonal brace 112 are welded.

[0039] Furthermore, the gap between the frame connection part 131 and the reinforcement flange 123 is filled with a resin layer. During operation, a gap is reserved between the frame connection part 131 and the reinforcement flange 123. After the welding of the diagonal brace 112 and the frame connection part 131 is completed, the resin layer is formed by filling and curing the resin. The provision of the resin layer not only increases the pressure bearing capacity of the reinforcement flange 123, but also increases the connection strength between the frame and the tank body 12.

[0040] In this embodiment, the tank body connection part 132 is closely attached to the outer wall of the tank body 12, and the covering member 14 completely covers the tank body connection part 132 to achieve the connection between the connection member 13 and the tank body 12. In other embodiments, there may also be a gap between the tank body connection part 132 and the outer wall of the tank body 12, and the gap between the tank body connection part 132 and the tank body 12 is filled by the covering member 14.

[0041] The covering member 14 is made of a non-metal composite material and is formed by covering the outer surface of the tank body 12 and curing. Specifically, the covering member 14 includes fiber layers and resin layers that are alternately stacked. The fiber layers and the resin layers are alternately covered and cured, that is, a fiber layer, a resin layer, and then a fiber layer are stacked in sequence to obtain the covering member 14, so that the covering member 14 and the cylinder 121 of the tank body 12 are integrated to ensure the connection strength.

[0042] Preferably, the fiber layer is a fiber cloth or a fiber felt. The fiber cloth or the fiber felt is glass fiber, carbon fiber, aramid fiber or other fiber materials. The specific selection can be made according to the use of the tank body 12.

[0043] Furthermore, the resin may be epoxy resin, ethylene oxide resin, phenolic resin or other thermosetting resins that are compatible with the medium in the tank body 12 , and the specific resin may be selected according to the medium loaded in the tank body 12 .

[0044] See also Figure 3The covering member 14 can also be arranged around the outer periphery of the tank body 12 and located on both sides of the reinforcing flange 123. By winding the fiber and the resin around both sides of the reinforcing flange 123 and solidifying them, not only the connection strength between the tank body 12 and the frame can be increased, but also the pressure bearing capacity of the tank body 12 can be increased.

[0045] The standard tank container of this embodiment is connected by welding the frame connection part to the diagonal brace of the frame, and then the outer surface of the tank body 12 is covered with a covering part made of non-metallic composite material and completely covers the tank body connection part 132, and the frame connection part 131 and the tank body connection part are integrally formed, that is, a reliable connection between the non-metallic tank body 12 and the metal frame is achieved by combining welding and covering, and the connection strength can meet various load conditions and usage conditions of the tank container, which is conducive to the promotion and application of non-metallic tank bodies.

[0046] Example 2

[0047] See also Figure 4-Figure 6 The present embodiment provides a swap body tank container (SWAPBODY) 1, comprising: a tank body 22, a frame supporting the tank body, a connecting member 23 and a covering member 24.

[0048] Similar to the first embodiment, the material of the tank body 22 in this embodiment is also a non-metallic composite material, so there is no joint seam between the ordinary cylinder body and the head. In this embodiment, the tank body 22 is divided into a cylinder body 221 and a head 222, which is mainly distinguished according to their shapes and positions, and does not represent the actual composition structure of the tank body 22. The two ends of the tank body 22 extend out of the two end frames 211 of the frame respectively. Specifically, the head 22 of the tank body 22 extends out of the end frame 211.

[0049] The outer wall of the tank body 22 is also provided with a limit convex edge 224 protruding along the circumferential direction. Specifically, along the length direction of the tank body 22, two limit convex edges 224 are provided at intervals, respectively corresponding to the two end frames 211. The material of the limit convex edge 224 is a non-metallic composite material. In this embodiment, the limit convex edge 224 is integrally formed on the tank body 22. In other embodiments, the limit convex edge 224 can also be fixed to the tank body 22 by bonding, fusing, etc.

[0050] See also Figure 2 The frame includes two end frames 211, diagonal braces 212, side braces 213 and stoppers 214. The end frame 211 includes two corner columns 2111, an upper end beam 2112 connecting the two corner columns 2111, a lower end beam 2113 and corner pieces 2114. The diagonal braces 212 are connected to each corner piece 2114.

[0051] The stopper 214 protrudes from the inner periphery of the end frame 211 and abuts against the stopper convex edge 224 on the tank body 22. Specifically, the stopper 214 is made of metal. In this embodiment, the stopper 214 is circular as a whole, surrounds the outer periphery of the tank body 22, and is integrally formed, or it can be formed by welding and splicing a plurality of arc-shaped parts. In other embodiments, the stopper 214 can also be a plurality of stopper blocks, which are respectively fixed on the end frame 211 and abut against the stopper convex edge 224.

[0052] Preferably, a support plate 2141 is provided on the inner wall of the stopper 214, and the support plate 2141 has an arc surface adapted to the outer periphery of the tank body 22, and is used to support the tank body 22. In this embodiment, the support plates 2141 are respectively provided at the top and bottom of the tank body 22, and provide support and fixation in the vertical direction of the tank body 22 due to its own weight and possible vibration during transportation. In other embodiments, each can be provided according to actual needs.

[0053] In this embodiment, the limiting member 214 and the supporting plate 2141 are made of an integral angle steel. In other embodiments, the supporting plate 2141 and the limiting member 214 may be independent of each other and connected by welding.

[0054] Furthermore, a plurality of connecting ribs 2142 are arranged at intervals along the circumferential direction of the limiting member 214, and the two ends of each connecting rib 2142 respectively fix the limiting member 214 with the corner column 2111, the upper end beam 2112, and the lower end beam 2113 of the end frame 211, thereby improving the connection strength between the limiting member 214 and the end frame 211.

[0055] Along the length direction of the tank body 22, the direction in which the two end frames 211 face each other is the inner side, and the direction in which the two end frames 211 face away from each other is the outer side. Figure 6 The end frame 211 is located on the outside, the limiting member 214 abuts against the inner side of the end frame 211, the limiting convex edge 224 abuts against the inner side of the limiting member 214, and the limiting convex edge 224 is fixedly connected to the tank body 22. When the outside world applies force to the tank body 22 and makes the tank body 22 move along the longitudinal direction, the tank body 22 will drive the limiting convex edge 224 to move together, and the limiting member 214 and the end frame 211 limit the movement of the limiting convex edge 224, thereby limiting the movement of the tank body 22.

[0056] Furthermore, the cross-sectional shape of the limiting protrusion 224 may be a right-angled trapezoid, a right-angled sector, or other irregular shapes to ensure that the limiting protrusion 224 abuts against the limiting member 214 .

[0057] The structures of the reinforcing flange 223, the connecting member 23 and the covering member 24 on the tank body 22 are respectively the same as the structures and connection principles of the reinforcing flange 113, the connecting member 13 and the covering member 14 in the standard tank container 1 in Example 1, and are not described in detail here.

[0058] The exchange tank container 2 of this embodiment realizes a reliable connection between the non-metallic tank body 22 and the metal frame through the connecting member 23 and the covering member 24, and then the tank body 22 is longitudinally limited by the limiting member 214 protruding from the inner periphery of the end frame 211 abutting against the limiting convex edge 224 on the tank body.

[0059] It can be seen from the above technical scheme that the advantages and positive effects of the present invention are: the tank container of the present invention is connected by welding the frame connecting part of the connecting piece with the diagonal brace of the frame, and then the covering part of the non-metallic composite material is covered on the outer surface of the tank body and completely covers the tank body connecting part of the connecting piece, and the connecting piece is an integrally formed structure, that is, a reliable connection between the non-metallic tank body and the metal frame is achieved by combining welding and covering, and the connection strength can meet various load conditions and usage conditions of the tank container, which is conducive to the promotion and application of non-metallic tank bodies.

[0060] The above are only preferred feasible embodiments of the present invention and are not intended to limit the protection scope of the present invention.
