Description

Technical Field

[0001] This application relates to the field of container technology, and in particular to a bottom brace, end frame assembly, and tank container having the same. Background Technology

[0002] To simplify the overall frame structure, existing tank containers use end frames and bottom braces to support the tank body. However, during thermal expansion and contraction, tank containers experience localized stress concentrations in several areas, such as the connection between the bottom brace and the tank body, and the small-diameter arc area of ​​the end cap. Existing technologies, such as Chinese invention patent CN102745433B, disclose a tank transport device where the bottom brace connects to the tank body via an open box-like structure. While this structure increases connection strength to some extent, the tank body experiences alternating temperatures due to the stored medium and environmental factors, leading to thermal expansion and contraction. The stress generated by this expansion and contraction tends to concentrate in the box-like structure, making it prone to fatigue cracks and even fractures. 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, one objective of this application is to provide a bottom brace that solves the problem of local stress concentration and fatigue cracking in the tank body caused by alternating hot and cold temperatures. Another objective of this application is to provide an end frame assembly that can stably support the tank body. A further objective of this application is to provide a tank container with good support stability, where the bottom brace is less prone to fatigue cracking, eliminating the need for frequent welding repairs and replacements of the bottom brace.

[0004] To achieve the above-mentioned technical objectives and meet the above-mentioned technical requirements, the technical solution adopted in this application is as follows: This application provides a bottom brace, characterized in that it includes a bottom brace body inclinedly disposed on an end frame and a buffer assembly disposed at one end of the bottom brace for buffering and dispersing stress.

[0005] As a preferred technical solution, the buffer assembly includes two wing plates respectively disposed on one side of the bottom inclined brace body.

[0006] As a preferred technical solution, the wingplate has a connecting plate a and a support plate a bent and disposed on one side of the connecting plate a, and the connecting plate a and the support plate a are connected to form an integral wing-shaped structure.

Detailed Implementation

[0025] The present application will now be further described with reference to the accompanying drawings.

[0026] 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.

[0027] Please refer to Figures 1-10 One embodiment of this application provides a bottom brace, including a bottom brace body 1 inclinedly disposed on the end frame and a buffer assembly disposed at one end of the bottom brace body 1. The bottom brace body 1 does not directly contact the cylinder 12 or the pad 8. The buffer assembly provides buffering when the tank expands and contracts with heat, and can also disperse local stress, thus solving the problem of local stress concentration and fatigue cracking of the tank caused by alternating hot and cold temperatures.

[0028] like Figures 1-10As shown, the bottom bracing body 1 is further made of square tube, channel steel or round tube to ensure structural strength while achieving lightweight. The bottom bracing body 1 can also be a solid structure, but the weight will be larger.

[0029] like Figures 1-10 As shown, a pad 8 is provided at the upper end of the buffer assembly. The pad 8 is connected to the cylinder 12. The buffer assembly can be directly connected to the cylinder 12, or indirectly connected to the cylinder 12 through the pad 8. The pad 8 reduces the impact of local stress concentration on the cylinder 12.

[0030] like Figures 1-10 As shown, the buffer assembly includes two wing plates 2 respectively disposed on one side of the bottom inclined support body 1. The two symmetrically disposed wing plates 2 form a buffer space, which provides buffering and disperses local stress when the tank expands and contracts with heat. Furthermore, the wing plate 2 includes a connecting plate a201 and a support plate a202 bent and disposed on one side of the connecting plate a201. The connecting plate a201 and the support plate a202 are connected to form an integrated wing-shaped structure. The wing-shaped structure formed by the support plate a202 and the connecting plate a201 can compensate for the deformation caused by thermal expansion and contraction to a certain extent.

[0031] like Figures 1-10 As shown, the connecting plate a201 has an inclined edge, and the support plate a202 is connected to the inclined edge. The inclined edge is used to change the direction, so that the support plate a202 matches the cylinder 12 or the pad plate 8, and the force-bearing structure is reasonable.

[0032] like Figures 1-10 As shown, the connecting plate a201 has a trapezoidal structure. Furthermore, the connecting plate a201 has a connecting part 2011 and an inclined part 2012 connected to the connecting part 2011. The inclined part 2012 has the inclined side. The inclined part 2012 and the connecting part 2011 are connected to form a right trapezoidal integral structure. The connecting part 2011 is connected to the bottom inclined support body 1, and the inclined part 2012 is connected to the support plate a202. The structure is reasonable and has good stability.

[0033] like Figures 1-10 As shown, a reinforcing corner piece 5 is provided on one side of the support plate a202. The reinforcing corner piece 5 is connected to the support plate a202 and the bottom inclined brace body 1 respectively. The reinforcing corner piece 5 enhances the structural strength of the wing plate 2. Furthermore, the support plate a202 and the connecting part 2011 will form a notch. The reinforcing corner piece 5 is set in the notch to enhance the strength here. Furthermore, the shape of the reinforcing corner piece 5 is triangular, trapezoidal or triangular-like with curved edges.

[0034] like Figures 1-10As shown, the support plate a202 is inclinedly disposed at the lower part of the cylinder 12. The support plate a202 can also be configured to match and fit with the cylinder 12 or the pad 8 to form a surface contact, but the process is complicated. In actual production, in order to improve work efficiency, the support plate a202 is inclinedly disposed at the lower part of the cylinder 12 to form a line contact, which can also meet the conventional support requirements. The inclined placement of the support plate a202 provides a buffer space between the support plate a202 and the cylinder 12, reducing local stress concentration.

[0035] like Figures 1-10 As shown, the support plate a202 is connected to the side facing the cylinder 12 with a support reinforcement 6. Since the support plate a202 is inclined, the support plate a202 forms a line contact with the cylinder 12 or the pad 8. The support reinforcement 6 strengthens the connection between the support plate a202 and the cylinder 12 or the pad 8 and improves the support effect. Furthermore, the support reinforcement 6 is triangular or trapezoidal in shape.

[0036] like Figures 1-10 As shown, an intermediate reinforcing member 7 is provided between the two inclined portions 2012. The intermediate reinforcing member 7 can connect the two inclined portions 2012 together and increase the overall strength of the connecting plate 201.

[0037] like Figures 1-10 As shown, the upper edge of the support plate a202 is provided with a folded edge a2021. The folded edge a2021 can increase the contact area between the support plate a202 and the cylinder or pad, making the connection more secure. The folded edge a can also strengthen the strength of the support plate a.

[0038] like Figures 1-10 As shown, the buffer assembly includes a connecting plate b3 and support plates b4 bent and disposed on both sides of the connecting plate b3. One end of the bottom inclined support body 1 is provided with an inclined surface. The connecting plate b3 is connected to the inclined surface. The support plate b4 is bent outward. The connecting plate b3 and the support plate b4 are connected to form a trapezoidal groove. The inclined surface of the bottom support body 1 is parallel to the central axis of the cylinder 12. When the support plate b4 is connected to the cylinder 12 or the pad 8, the stress structure is reasonable. The connection between the connecting plate b3 and the support plate b4 forms a trapezoidal groove, which has good structural stability. A buffer space is formed between the two support plates b4. The support plate b4 can provide buffering when the tank expands and contracts with heat, disperse local stress, and solve the problem of local stress concentration and fatigue cracking of the tank caused by alternating hot and cold temperatures.

[0039] like Figures 1-10 As shown, the upper edge of the support plate b4 is provided with a folded edge b401. The folded edge b401 can increase the contact area between the support plate b4 and the cylinder 12 or the pad 8, making the connection more secure. The folded edge b401 can also strengthen the support plate b4.

[0040] like Figures 1-10 As shown, to further enhance strength, reinforcing members can also be installed on the support plate b4 and the connecting plate b3, which will not be elaborated further.

[0041] like Figures 1-10 As shown, the end face of the bottom brace body 1 with the buffer assembly is connected to a sealing plate 9, which can strengthen the end strength of the bottom brace body 1.

[0042] like Figures 1-10 As shown, the buffer assembly includes an inclined end plate 17 and an arc plate 18 connected to the inclined end plate. One end of the bottom inclined support body 1 is provided with an inclined surface. The inclined end plate 17 is connected to the inclined surface. The two ends of the arc plate 18 are respectively connected to the cylinder 12 or the pad 8. The arc plate 18 has a buffer space, which can provide buffering and distribute stress.

[0043] Please see Figures 1-10 This application also provides an end frame assembly, including a first end frame 10 and a second end frame 11 arranged opposite to each other, and the bottom bracing. The bottom of the first end frame 10 is connected to two bottom bracings, and the bottom of the second end frame 11 is connected to two bottom bracings. The two bottom bracings of the first end frame 10 are symmetrically arranged, and the two bottom bracings of the second end frame 11 are symmetrically arranged, which can provide stable support for the tank.

[0044] Please see Figures 1-10 This application also provides a tank container, including a tank body, a first skirt 15, a second skirt 16, and the end frame assembly. The tank body has a cylindrical body 12 and a first end cap 13 and a second end cap 14 disposed at both ends of the cylindrical body 12. The buffer assembly is connected to the lower part of the cylindrical body 12, providing good support stability. The bottom diagonal brace is not prone to fatigue cracks and does not require frequent welding and replacement of the bottom diagonal brace.

[0045] The buffer assembly has a symmetrical structure. The plane facing the first end cap 13 is the projection plane. The projection of the central axis of the buffer assembly onto the projection plane is the first central axis, and the projection of the vertical central axis of the cylinder onto the projection plane is the second central axis. The angle between the first central axis and the second central axis is 30°-60°. Within this range, the bottom inclined brace provides good support for the tank. The optimal angle between the first central axis and the second central axis is 45°.

[0046] Any numerical values ​​cited herein include all values ​​ranging from a lower limit to an upper limit, increasing by one unit, with at least two units between any lower and any higher value. For example, if the quantity of a component or the value of a process variable (e.g., temperature, pressure, time, etc.) is described as being from 1 to 90, preferably from 20 to 80, more preferably from 30 to 70, the purpose is to illustrate that values ​​such as 15 to 85, 22 to 68, 43 to 51, 30 to 32 are also explicitly listed in this specification. For values ​​less than 1, a unit is appropriately considered to be 0.0001, 0.001, 0.01, 0.1, etc. These are merely examples intended for explicit expression, and it can be assumed that all possible combinations of values ​​listed between the minimum and maximum values ​​are explicitly described in this specification in a similar manner.

[0047] Unless otherwise stated, all ranges include the endpoints and all numbers between them. The terms "approximately" or "about" used with ranges apply to both endpoints of the range. Thus, "approximately 20 to 30" is intended to cover "approximately 20 to approximately 30," including at least the specified endpoints.
