Although certain features may be combined together to illustrate possible system designs, these features are also applicable to other combinations not explicitly illustrated. Accordingly, the illustrated combinations are not intended to be limiting, unless otherwise indicated.

In the embodiments shown in the figures, the indication of directions (such as up, down, left, right, front and back) is used to explain that the structure and motion of the various elements of the present invention are not absolute but relative. These descriptions are suitable when the elements are in the positions shown in the figures. If the description of the position of these elements changes, the indications of these directions also change accordingly.

The preferred embodiments of the present invention are further described in detail below with reference to the drawings of the specification.

Referring to Figure 1, the present invention provides a tank container and its end frame structure.

The can container of the present embodiment includes a can body and an end frame structure 2 provided at both ends of the can body. Both ends of the can body are fixed by the end frame structure 2, and the ends of the can body are provided with a head. The head passes through the frame structure 2 at both ends. For convenience of explanation, the end of the can body near the front end is the front end, and the other end of the can body is the tail end. Therefore, the frame structure 2 at both ends is a front end frame and a rear end frame, respectively. Both ends of the can body are fixed by the front end frame and the rear end frame, and the head passes through the front end frame and the rear end frame respectively.

The tank is a super-large tank. The distance between the front end frame and the back end frame is 30Ft or 40Ft.

Referring to FIGS. 1 and 2 , the end frame structure 2 includes an upper beam 21 , a lower beam 22 , two corner posts 23 , and four corner pieces 24 .

The corner piece 24 includes two corner pieces 241 disposed at the top end of the two corner posts 23 and a bottom corner piece 242 disposed at the bottom end of the two corner posts 23. Both ends of the upper beam 21 are respectively connected to the two corner pieces 241, and two ends of the lower beam 22 are respectively connected to the two corner pieces 242. The top corner piece 241 and the bottom corner piece 242 are casting parts or welded parts, and the top corner piece 241 and the bottom corner piece 242 have a yield strength of 420 MPa or more, so as to meet the demand for large and easy tank transportation.

Moreover, the distance between the two corner pieces 241 is 2438 mm, and the distance between the two corner pieces 242 is less than or equal to 2600 mm, so that the corner hole can be matched with the railway, highway, and shipping corner pieces. It can be understood that the distance between the two corner pieces 241 and the two bottom corner pieces 242 can also be the same as long as the corner piece lock transporting use requirements can be satisfied.

The upper beam 21 is disposed opposite to the lower beam 22. The upper beam 21 and the lower beam 22 are tubular structures, for example, square tubes or round tubes. A lifting protection plate 26 is provided at the junction of the upper beam 21 and the corner piece 241. The hoisting protection plate 26 is triangular. The hoisting protection plate 26 connects the upper beam 21 and the beam 3 between the frame structures 2 at both ends. The hoisting protection plate can strengthen the strength of the joint of the upper beam 21, the corner piece 241 and the beam 3 to prevent damage during the hoisting process.

The lower beam 22 is provided with a relief groove 221. The escape groove 221 is used to avoid a fixed lock or the like on the frame. When the end frame structure 2 is prevented from being placed on the frame, the lower beam 22 is collided, causing damage. The lower beam 22 is provided with a connection block 222 at the escape groove 221 . The connecting block 222 connects the lower beam 22 with the bottom corner piece 242. The connecting block 222 can strengthen the strength of the lower beam 22 and the escape groove 221, and prevent the lower beam 22 from affecting the overall strength of the lower beam 22 due to the opening of the escape groove 221. The width of the connecting block 222 is equal to the width of the lower beam 22. One end of the connecting block 222 abuts against the inner side surface 235 of the corner post 23. The other end of the connecting block 222 is provided with a cut surface 223. The cut surface 223 is adapted to the outer surface of the can body. It can be understood that the connecting block 222 is a rectangular square tube.

Specifically, in the present embodiment, the length of the lower beam 22 is smaller than the distance between the two bottom corner pieces 242, and therefore, the escape groove 221 is formed by the end surface of the lower beam 22 and the side surface of the bottom corner piece 242.

Moreover, the lower beam 22 is provided with a curved surface 224 which is adapted to the surface of the can body. When the can body is in contact with the lower beam 22, the curved surface 224 can better securely support the can body.

Referring to FIG. 3, the two corner posts 23 are spliced to each other by the corner members 24 and the upper beam 21 and the lower beam 22 to form a frame 20. The corner post 23 faces the inner side surface 235 of the corner post 23 toward the inner side of the frame 20, and the side opposite to the inner side surface 235 is the outer side surface 236 of the corner post 23.

The corner post 23 includes a body 231 and a reinforcing portion 232. The body 231 and the reinforcing portion 232 are arranged side by side in the axial direction of the can body, and the reinforcing portion 232 is adapted to the body 231 and encloses a tubular structure. The body 231 and the reinforcing portion 232 are spliced into a tubular corner post 23.

The width of the reinforcing portion 232 in the axial direction of the can body is uniform. The cross-sectional area of the middle portion of the reinforcing portion 232 is equal to the cross-sectional area of both ends of the reinforcing portion 232.

Specifically, in the present embodiment, the cross-sectional area of the middle portion of the reinforcing portion 232 is equal to the cross-sectional area of both ends. The width of the corner posts 23 in the axial direction of the can body is uniform. That is, the corner post 23 is a rectangular square tube. The main body 231 and the reinforcing portion 232 are steel materials in which square grooves are opened. The reinforcing portion 232 reinforces the strength of the corner post 23 from one side of the body 231.

The reinforcing portion 232 and the body 231 have an integral structure.

Further, the reinforcing portion 232 widens the end surface of the corner post 23 in the axial direction of the can body, thereby increasing the connection area between the corner post 23 and the corner piece 24, and enhancing the connection strength between the corner post 23 and the corner piece 24.

Since the corner post 23 is constituted by the body 231 and the reinforcing portion 232. Then, the length of the corner post 23 in the axial direction of the can body is large, and the length of the corner post 23 in the axial direction perpendicular to the can body is small. Therefore, the corner post 23 can be connected to the outer portion of the corner piece 24, so that the distance between the inner side faces 235 of the two corner posts 23 can be increased. The distance between the inner side faces 235 of the two corner posts 23 is greater than the distance between the two corner pieces 241 or the two bottom corner pieces 242. Therefore, the distance between the two corner posts 23 is increased without affecting the hoisting and transportation of the integral tank container, so that the end frame structure 2 can fix a larger volume of the can body.

Specifically, in the present embodiment, the outer side surface 236 of both ends of the corner post 23 is provided with a slope 233. The inclined surface 233 is bent toward the inner side surface 235 of the corner post 23, and the angle between the inclined surface 233 and the inner side surface 235 of the corner post 23 is an acute angle. In the height direction of the corner post 23, the area of the cross section gradually decreases, ensuring that both ends of the corner post 23 can be connected to the corner piece 24.

In other embodiments, the width of the reinforcing portion 232 in the axial direction of the can body is increasing from the upper and lower ends toward the middle portion. Referring to FIG. 4, the cross-sectional area of the middle portion of the reinforcing portion 232 is larger than the cross-sectional area of both ends of the reinforcing portion 232. The corner post 23 has an increasing tendency from the both ends to the middle in the width along the axial direction of the can body. In the axial direction of the can body, the width of the central portion of the corner post 23 is increasing with respect to the width of both ends, and the strength of the corner post 23 itself can be enhanced.

It can be understood that the corner post 23 can also be formed by splicing the square tube, square tube or round tube or plate.

Therefore, under the premise of ensuring its own strength and the strength of the connection with the corner piece 24, the corner post 23 maximizes the distance between the two corner posts 23, so that the end frame structure 2 can fix a larger volume of the can body.

An arcuate groove 234 is formed on the inner side surface 235 of the corner post 23 to fit the can body. In one aspect, the two arcuate slots 234 can further enlarge the distance between the inner side surfaces 235 of the two corner posts 23 to enable the end frame structure 2 to secure a larger volume of can body; on the other hand, the curved slots 234 enable the corner posts 23 to be hooped. The tank body is used to enhance the stability of the connection between the tank body and the end frame structure 2.

The height of the corner post 23 is less than or equal to 2743 mm, or the height of the corner post is less than or equal to 2896 mm.

Referring also to FIG. 1 , the end frame structure 2 further includes a connecting plate 25 . The connecting plate 25 covers one side of the frame 20. The connecting plate 25 is cap-connected to the frame 20 at least from one side of the frame 20.

Specifically, in the present embodiment, the connecting plates 25 may be two, and the two connecting plates 25 are spaced apart from each other and disposed on the front side and the rear side of the frame 20, and are enclosed with the frame 20 to form a box-like structure. The peripheral edge of the connecting plate 25 is welded to the peripheral edge of the frame 20. The connecting plate 25 covers the frame 20 in a box-like structure to enhance the strength of the end frame structure 2. The connecting plate 25 is a rib to improve the strength of the end frame structure 2.

The shape of the connecting plate 25 is adapted to the shape of the frame 20. The connecting plate 25 is provided with a through hole 251 through which the can body passes. Also, the edge of the via 251 is aligned with the arc of the corner post 23. Both ends of the can body protrude from the through hole 251 of the connecting plate 25. When the outer surface of the can body is connected to the through hole 251, the inertial force received by the can body can be transmitted to the connecting plate 25.

A reinforcing plate 252 is vertically disposed between the two connecting plates 25. The reinforcing plate is vertically located within the box-like structure. The reinforcing plate 252 reinforces the strength of the box-like structure. Also, the reinforcing plate 252 is extended from the corner piece 241 and the bottom corner piece 242 to the through hole 251. There are a plurality of reinforcing plates 252. When lifting or transporting the can body, stress is transmitted from the can body to the corner piece 24 by the reinforcing plate 252 to be released.

Further, the end frame structure 2 is further provided with a reinforcing tube 253. The connecting plate 25 is also provided with a hole 254. The reinforcing tube 253 is disposed between the two connecting plates 25, and the opening of both ends of the reinforcing tube 253 is opposed to the hole 254. The stress of the connecting plate 25 can be released through the hole 254, and the reinforcing tube 253 can enhance the strength of the end frame structure 2.

In other embodiments, the connecting plate 25 is one. The connecting plate 25 may be provided on the front side or the rear side of the frame 20. Alternatively, the connecting plate 25 is provided on the inner side of the frame 20, and the connecting plate 25 is located on the center surface of the frame 20. The center plane of the frame 20 is the central section of the frame 20 along the radial direction of the can body. The connecting plate 25 reinforces the strength of the end frame structure 2 inside the frame 20.

It can be understood that the connecting plate 25 can be welded by a plurality of sheet metal, or can be a unitary structure.

In the end frame structure of the above-mentioned tank container, by designing the shape of the corner post, the width of the corner post 23 is increased in the axial direction of the tank body, so that the strength of the corner post is strengthened, so that the load of the end frame structure can satisfy 78 tons.
