Description

Technical Field

[0001] This application relates to the field of tank container technology, and more particularly to an end frame and a tank container having the same. Background Technology

[0002] In tank containers, the end frames are welded to the connecting rings on the end caps to secure the tank body. Existing technology uses diagonal supports at the corners of the end frames to increase their strength, with the width of the diagonal supports matching the width of the end frames. However, some tank containers increase their axial length for the end caps or cylinder to increase volume, allowing the tank to hold more media. Alternatively, some special box shapes, such as square, round, or oblong tank containers, typically have narrower connecting rings, causing the distance between the end caps and end frames to be closer. During assembly, the curved surface of the end caps can easily interfere with the diagonal supports, necessitating a wider distance between the end frames and end caps. This results in a less compact overall structure, further increasing the overall length of the tank container and hindering loading and transportation. Therefore, a new technical solution is urgently needed to address at least one of these technical problems. Summary of the Invention

[0003] In view of the above-mentioned shortcomings, the purpose of this application is to provide an end frame and a tank container having the same, wherein the clearance groove can avoid the end cap and prevent the end cap from interfering with the diagonal support. Another purpose of this application is to provide a tank container in which the diagonal support can avoid the end cap, thereby increasing the axial length of the tank and increasing its volume.

[0004] To achieve the above-mentioned technical objectives and meet the above-mentioned technical requirements, the technical solution adopted in this application is: An end frame, characterized in that it includes an end frame body, wherein at least one corner of the end frame body is provided with an oblique support, and the oblique support is provided with a relief groove for avoiding the end cap on the side facing the end cap.

[0013] As a preferred technical solution, one of the vertical corners of the corner post is provided with a clearance notch for avoiding the end cap, and the clearance notch extends vertically.

[0024] The present application will now be further described with reference to the accompanying drawings.

[0025] In the accompanying drawings of the embodiments of this application, the same or similar reference numerals correspond to the same or similar components. In the description of this application, it should be understood that if terms such as "top", "bottom", "left", "right", "front", "rear", "inner", "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this application, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0026] Please refer to Figures 1-6 An embodiment of this application provides an end frame, including an end frame body 1. The end frame body 1 has at least one corner where a diagonal support 2 is provided. The diagonal support 2 has a relief groove 201 on the side facing the end cap for avoiding the end cap. The relief groove 201 can avoid the end cap and prevent the end cap from interfering with the diagonal support 2. The diagonal support 2 can avoid the end cap, so that the axial length of the tank can be increased and the volume can be increased. Moreover, the structure between the end frame and the end cap is compact, saving axial space.

[0027] like Figures 1-6 As shown, the clearance groove 201 is an arc-shaped groove. The arc-shaped clearance groove 201 can avoid the end cap and prevent the end cap from interfering with the inclined support 2.

[0028] like Figures 1-6 As shown, the clearance groove 201 is a trapezoidal groove, which has sufficient clearance space and good stability of trapezoidal structure.

[0029] like Figures 1-6 As shown, the clearance groove 201 includes a first oblique line segment 202, a first straight line segment 203, and a second oblique line segment 204 connected in sequence. The first oblique line segment 202, the first straight line segment 203, and the second oblique line segment 204 form a trapezoidal structure. The first straight line segment 203 provides a good clearance space in the middle of the clearance groove 201, while the isosceles structure avoids excessive thinning at both ends of the oblique support 2, which would affect its strength.

[0030] like Figures 1-6 As shown, the clearance groove 201 includes a first arc segment 205, a second straight segment 206, and a second arc segment 207 connected in sequence. The first arc segment 205 and the second arc segment 207 increase the clearance space and match the end cap. Compared with the arc-shaped clearance groove 201, the second straight segment 206 makes the whole structure have a trapezoidal shape. The clearance groove 201 is thicker in the middle and has higher overall strength.

[0031] like Figures 1-6As shown, the inclined support 2 is a hollow structure, generally made of square tube or channel steel, and then a clearance groove 201 is cut out on one side of the square tube or channel steel.

[0032] like Figures 1-6 As shown, the clearance groove 201 is provided with a first reinforcing plate 3. The first reinforcing plate 3 matches the shape of the clearance groove 201. The first reinforcing plate 3 is connected to the inclined support 2. If the clearance groove 201 is arc-shaped, the first reinforcing plate 3 is arc-shaped. If the clearance groove 201 is an isosceles trapezoid, the first reinforcing plate 3 is a plate-shaped structure bent into an isosceles trapezoid to match it. If the clearance groove 201 includes a first arc segment 205, a second straight segment 206 and a second arc segment 207 connected in sequence, the first reinforcing plate 3 matches it. When the inclined support 2 is a square tube and a channel steel, the strength is increased by using the first reinforcing plate 3.

[0033] like Figures 1-6 As shown, specifically, there are two diagonal supports 2, which are connected to the corner column 103 and the end beam 102 respectively. The structure is simple and practical.

[0034] like Figures 1-6 As shown, the inclined support 2 is internally connected with multiple reinforcing ribs 8. The inclined support 2 can be made of square tube or channel steel. If the first reinforcing plate 3 is not used, multiple reinforcing ribs 8 can be welded inside the inclined support 2 to increase the overall strength.

[0035] like Figures 1-6 As shown, the end frame body 1 includes an upper end beam 101, a lower end beam 102, two upper corner pieces 104 respectively disposed at both ends of the upper end beam 101, and two lower corner pieces 105 respectively disposed at both ends of the lower end beam 102. A corner post 103 is disposed between the upper corner pieces 104 and the lower corner pieces 105 arranged side by side. Furthermore, an avoidance opening 1021 is provided in the middle of the lower end beam 102. An avoidance notch 9 is provided at the corner of the avoidance opening 1021 facing the end cap. The avoidance opening 1021 can prevent the bottom valve 6 from interfering with the lower end beam 102, and the avoidance notch 9 can avoid the rod 7 of the bottom valve 6.

[0036] like Figures 1-6 As shown, one of the vertical corners of the corner post 103 is provided with a clearance notch 208 for avoiding the end cap. The clearance notch 208 extends vertically and can further increase the clearance space. While the tank capacity increases, the space between the end frame and the end cap becomes more compact, avoiding space waste.

[0037] like Figures 1-6As shown, the clearance notch 208 includes a first inclined surface 2081, a middle surface 2082, and a second inclined surface 2083 connected sequentially from top to bottom. Due to the structural characteristics of the end cap, the first inclined surface 2081 and the second inclined surface 2083 enable the clearance notch 208 to have a sufficient clearance angle, which facilitates clearance of the end cap.

[0038] like Figures 1-6 As shown, the intermediate surface 2082 is either arc-shaped or flat. The first inclined surface 2081, the intermediate surface 2083, and the second inclined surface 2083 are flat. The intermediate surface 2082 is arc-shaped to match the end cap. The intermediate surface 2082 can also be set as a flat surface to avoid the thickness of the corner post 103 being too thin.

[0039] like Figures 1-6 As shown, the clearance notch 208 is arc-shaped, and the clearance notch 208 can also be set as an arc shape as a whole to match the shape of the end cap.

[0040] like Figures 1-6 As shown, the clearance notch 9 is provided with a second reinforcing plate 4, which is connected to the lower end beam 102. Since the lower end beam 102 is generally made of square tubing, the strength of this area is low after the clearance notch 9 is processed, and it is easy to cut workers. Adding the second reinforcing plate 4 can enhance the strength and prevent workers from being cut. The structure of the second reinforcing plate 4 is a bent plate structure.

[0041] like Figures 1-6 As shown, a third reinforcing plate 5 is provided inside the avoidance opening 1021. The third reinforcing plate 5 has an avoidance inclined surface 501 on the side facing the end cap. The third reinforcing plate 5 is connected to the avoidance inclined surface 501, and the avoidance inclined surface 501 expands the avoidance area.

[0042] Please see Figures 1-6 This application also provides a tank container with the aforementioned end frames. Specifically, the two end frames of the tank container can use the same diagonal support 2 or the two end frames can use different diagonal supports 2. The diagonal support 2 can avoid the end cap, so that the tank body can increase its axial length and increase its volume.
