[0029] 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 essentially for illustrative purposes and not for limiting the present invention.

[0030] This embodiment provides a tank container and its frame. The tank container includes a tank body and a frame surrounding the outer periphery of the tank body. The frame includes two oppositely arranged end frames and a plurality of side beams provided between the end frames. Among them, the two end frames are respectively connected and fixed to the two axial ends of the tank body, and the bottom of the tank body is supported on the side beams at the bottom of the frame. A first engaging portion is attached to the end frame, and a second engaging portion for connecting the first engaging portion is attached to the side beam. The above-mentioned end frame and side beam can be separately manufactured, realizing step-by-step manufacturing to quickly form a complete frame structure. Since the end frame and side beam can be separately painted during manufacturing, there is no need to paint the formed frame as a whole, reducing the amount of paint and improving production efficiency.

[0031] The following will specifically introduce the frame of the tank container provided in this embodiment through several specific examples. For the tank container provided by the present invention, it can be formed by installing the tank body in the frames of the following various embodiments.

[0032] The First Embodiment of the Frame of the Tank Container

[0033] Please refer to Figure 1 and Figure 2 , Figure 1 , which shows the specific structure of a frame of a tank container provided in this embodiment. The frame mainly includes two end frames 1, four side beams 3, and a plurality of connecting members 5. Among them, the two end frames 1 are arranged opposite to each other at intervals, and a first engaging portion 11 protrudes from the end frame 1. The four side beams 3 are symmetrically distributed between the two end frames 1, and a second engaging portion 32 protrudes from each side beam 3 to be correspondingly clamped with the first engaging portion 11. The connecting member 5 detachably connects the first engaging portion 11 and the second engaging portion 32, thereby realizing the non-welded connection between the end frame 1 and the side beam 3, avoiding the damage to the end frame 1 caused by welding, and realizing the separate manufacturing of the end frame 1 and the side beam 3.

[0034] The end frame 1 includes a frame body 10 and four first engaging portions 11 protruding from the inner side of the frame body 10.

[0035] It is worth noting that the inner side is referenced by the opposite sides of the two end frames 1, and the opposite is the outer side.

[0036] Among them, the frame body 10 is a rectangular frame structure, including two relatively spaced columns 101, end upper beams and end lower beams (not shown) respectively provided at both ends of the two columns 101, corner pieces 103 respectively provided at both ends of the end upper beams, bottom corner pieces 104 respectively provided at both ends of the end lower beams, and multiple diagonal braces (not shown) respectively provided between the columns 101 and the end upper beams / end lower beams.

[0037] The four first engaging portions 11 are respectively arranged in one-to-one correspondence with the four corners of the frame body 10.

[0038] Each first engaging portion 11 includes a clamping protrusion 111a protruding from the inner side of the frame body 10 and a connecting plate 112 provided beside the clamping protrusion 111a.

[0039] The clamping protrusion 111a is rectangular.

[0040] One end of the connecting plate 112 that protrudes is provided with a connecting hole 1101 to be fixed to the second engaging portion 32 through the connecting hole 1101.

[0041] Specifically, the connecting plate 112 is generally L-shaped, and includes a side plate 1121 that fits and fixes to the inner side of the frame body 10 and a vertical plate 1123 bent from one side of the side plate 1121. Both the side plate 1121 and the vertical plate 1123 are rectangular. The vertical plate 1123 protrudes perpendicularly to the frame body 10, and a plurality of connecting holes 1101 are provided on the vertical plate 1123, and the plurality of connecting holes 1101 are arranged in a row at intervals in the vertical direction. The circumferential dimension of the side plate 1121 is larger than the circumferential dimension of the clamping protrusion 111a. The clamping protrusion 111a protrudes and is provided in the middle of the side of the side plate 1121 away from the frame body 10, and there is a gap between the clamping protrusion 111a and the vertical plate 1123.

[0042] Each side beam 3 is provided between two opposite corners of the two end frames 1. In this way, the four side beams 3 together with the end frames 1 form a hollow three-dimensional frame for horizontally or vertically installing a tank body.

[0043] The four side beams 3 are divided into two top side beams 3 and two bottom side beams 3. Among them, the top side beams 3 are provided between the top corners of the two end frames 1, and the bottom side beams 3 are provided between the bottom corners of the two end frames 1.

[0044] Each of the above side beams 3 includes a side beam main body 30 and two second engaging portions 32 respectively provided at both ends of the side beam main body 30. Each second engaging portion 32 and each first engaging portion 11 are arranged oppositely to form a clamping fit.

[0045] Among them, the side beam main body 30 is a hollow square tube structure, and its cross-section is rectangular.

[0046] The second engaging portion 32 is a rectangular seat body.

[0047] One end of the second engaging portion 32 has a rectangular opening with dimensions adapted to the circumferential dimension of the end of the side beam main body 30. The seat body can be sleeved and fixed on this end through this opening.

[0048] The other end of the second engaging portion 32 has a receiving groove 321. The receiving groove 321 has a rectangular profile adapted to the engaging protrusion 111a, so that the engaging protrusion 111a can enter and be closely received in the receiving groove 321.

[0049] The inner diameter of the receiving groove 321 is larger than the diameter of the opening of the receiving groove 321, thereby restricting the axial movement of the engaging protrusion 111a.

[0050] Furthermore, the opposite sides of the receiving groove 321 penetrate through the outer peripheral wall of the seat body, facilitating the engaging protrusion 111a to be aligned and enter the receiving groove 321 from the outside, increasing the operability. During the assembly process, the side beam 3 can be installed between the two end frames 1 from the side or the up and down directions of the frame through the above connection structure.

[0051] The receiving groove 321 is specifically a dovetail groove. The diameter of the receiving groove 321 gradually decreases from the inside to the outside in the direction close to the engaging protrusion 111a, and its cross-sectional shape is an isosceles trapezoid. Correspondingly, the engaging protrusion 111a has an outer contour adapted to the dovetail groove, forming a tight fit.

[0052] The seat body also has a plurality of through holes 301 on one side of the outer periphery around the receiving groove 321. The plurality of through holes 301 are correspondingly arranged with the connection holes 1101 on the upright plate 1123 of the connecting plate 112, and are detachably connected by bolts (connecting parts 5).

[0053] When the engaging protrusion 111a extends into the receiving groove 321, the upright plate 1123 fits against an outer side surface of the seat body from the side of the engaging protrusion 111a, and the first engaging portion 11 and the second engaging portion 32 are bolt-connected by fitting bolts through the through holes and the connection holes, thereby detachably fixing the side beam 3 to the end frame 1.

[0054] In this embodiment, the first engaging portion 11 has an engaging protrusion 111a, and the second engaging portion 32 has a corresponding receiving groove 321. In other embodiments, contrary to the above engaging method, the first engaging portion 11 may have a receiving groove 321, and the second engaging portion 32 has an engaging protrusion 111a, which can also form a detachable connection between the side beam 3 and the end frame 1.

[0055] In this embodiment, the side beam 3 is made of a square tube. In other embodiments, the side beam 3 can also be a round tube, an I-beam or other forms of section steel, and the shape of the second engaging portion 32 on the side beam 3 is correspondingly adapted.

[0056] In this embodiment, both the end frame 1 and the side beam 3 are made of carbon steel, which have relatively high strength and stiffness. However, they are relatively prone to rusting and thus require appropriate anti-corrosion treatments, such as painting or galvanizing. Since the end frame 1 and the side beam 3 are detachably connected, the end frame 1 and the side beam 3 can be separately pre-manufactured and painted independently without the need for overall painting after being assembled into a frame structure, reducing the workload of painting and lowering the labor intensity of workers. Moreover, due to the reduction in painting, the pollution caused by volatile substances in the paint to the environment can be reduced, meeting the increasingly stringent environmental protection requirements and having a wide adaptability.

[0057] In this embodiment, during the manufacturing process of the end frame 1, its first engaging portion 11 can be welded to the end frame 1 in advance, or it can be integrally cast with the corner fitting or part of the corner column of the end frame 1 by casting or forging in advance.

[0058] Second Embodiment of the Frame of the Tank Container

[0059] Please refer to Figures 3 to 4 together. The difference between the frame of the tank container provided in this embodiment and the frame of the first embodiment is that the first engaging portion 11 as a whole forms a locking projection 111b to be correspondingly received in the receiving groove 321 of the second engaging portion 32.

[0060] The first engaging portion 11 as a whole forms a locking projection 111b. The locking projection 111b is an I-beam, which includes an upper flange 114, a lower flange 115, and a web 116 vertically connecting the upper flange 114 and the lower flange 115.

[0061] The side beam main body 30 is a hollow square tube. One end of the side beam 3 with an opening forms the second engaging portion 32, and the opening forms a rectangular receiving groove 321. Two through holes 302 communicating with the receiving groove 321 are provided through the opposite two sides of the side beam 3.

[0062] During the assembly process, the upper flange 114 and the lower flange 115 are respectively closely attached to the upper and lower side walls of the receiving groove 321; the web 116 is supported between the two flanges, which can effectively prevent the locking projection 111b from falling out of the receiving groove 321. A through hole is provided on the web 116. The through hole is opposite to the through holes 302 on the two sides of the side beam 3 for a connecting member 5 to pass through, so as to realize the non-welded connection between the end frame 1 and the side beam 3, avoid the damage to the end frame 1 caused by welding, and realize the separate manufacturing of the end frame 1 and the side beam 3.

[0063] In this embodiment, the connecting member 5 is a pin shaft, and the through hole and the through hole are adapted shaft holes, which is convenient and fast and conducive to disassembly. In other embodiments, the connecting member 5 can be a bolt member, and the through hole and the through hole are adapted threaded holes. The connecting member 5 can also be a flange member to form a flange connection with the through hole and the through hole.

[0064] In this embodiment, the clamping protrusion 111b is an I-beam, which has an upper wing plate 114 and a lower wing plate 115 that are fitted to the upper and lower side walls of the receiving groove 321, forming a tight fit.

[0065] In other embodiments, the clamping protrusion 111b can be an L-shaped plate, which has two side plates 1121 perpendicular to each other to be fitted to two adjacent inner side walls in the receiving groove 321. The clamping protrusion 111b can be a concave plate or even a smaller-sized hollow square tube to completely fit the inner wall of the receiving groove 321.

[0066] In this embodiment, during the manufacturing process of the end frame 1, its first engaging portion 11 can be welded to the end frame 1 in advance, or it can be integrally formed with the corner piece or part of the corner column of the end frame 1 by casting or forging in advance.

[0067] In this embodiment, both the end frame 1 and the side beam 3 are made of carbon steel, having relatively high strength and stiffness, but being relatively prone to rusting and requiring appropriate anti-corrosion treatment, such as painting or galvanizing. Since the end frame 1 and the side beam 3 are detachably connected, the end frame 1 and the side beam 3 can be separately pre-manufactured and painted independently, without the need for overall painting after assembling to form a frame structure, reducing the painting workload and the labor intensity of workers. Moreover, due to the reduction of painting, the pollution caused by volatile substances in the paint to the environment can be reduced, meeting the increasingly stringent environmental protection requirements and having a wide adaptability.

[0068] 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.
