Description

Technical Field

[0001] This application relates to the field of container technology, and in particular to a bottom support structure for a tank container. Background Technology

[0002] Tank containers, also known as tank boxes, are ideal transport containers for loading and transporting large quantities of liquids or gases. A tank container consists of a cylindrical body, end caps at the ends of the body, and a connecting ring around the outer periphery of the end caps. Most tank containers require a discharge valve at the lowest point of the end caps for unloading. To avoid the discharge valve, a notch needs to be made in the connecting ring. The current method involves adding supporting angle steel on both sides of the notch, welding the supporting angle steel to the connecting ring, and then welding it to the end cap. However, this method results in stress concentration at the supporting angle steel, posing a risk, and the support effect at the bottom of the tank container and at the notch is still unsatisfactory, making it prone to deformation. Therefore, a new technical solution is urgently needed to solve at least one of the above technical problems. Summary of the Invention

[0031] Please refer to Figures 1-5This application provides a bottom support structure for a tank container according to one embodiment. The tank container includes a cylindrical body (not shown), a head 1 disposed on the cylindrical body, and a connecting ring 101 disposed on the head 1. The bottom support structure includes a reinforcing plate 2 disposed on the outer periphery of the bottom of the head 1, two support plates 3 respectively disposed on both sides of the reinforcing plate 2, and two pads 4. The support plate 3 has a reinforcing part 301 on the side facing the cylindrical body. The reinforcing part 301 is connected to the connecting ring 101. The pads 4 are correspondingly disposed with the reinforcing part 301 and are fitted to the cylindrical body and the head 1. One end of the pad 4 passes through the connection between the connecting ring 101 and the head 1. The pads 4 increase the stress-bearing area, and the reinforcing part 301 increases the stress-bearing area between the connecting ring 101 and the support plate 3, thereby strengthening the overall strength of the bottom support structure. The bottom support of the tank container is good, the connecting ring 101 and the tank container are not easily deformed, and the service life is extended.

[0032] like Figures 1-4 As shown, the reinforcing part 301 is connected to the support plate 3 to form a bent integral structure. The integral structure has better integrity and higher overall strength. The angle formed between the reinforcing part 301 and the support plate 3 is an obtuse angle. The reinforcing part 301 is in contact with the connecting ring 101.

[0033] like Figure 4 As shown, the reinforcing part 301 has a protrusion 302 on the outer side of one end facing the pad 4. The protrusion 302 is connected to the reinforcing part 301 to form an integral structure. The protrusion 302 further increases the contact area of ​​the force-bearing part and improves the support effect of the support plate 3. Specifically, the protrusion 302 includes an arc segment 3021 and a straight segment 3022 connected in sequence.

[0034] like Figure 5 As shown, the reinforcing plate 2 has an arc-shaped profile on the side facing the end cap 101 that matches the shape of the end cap 101. Both ends of the arc-shaped profile are provided with clearance grooves 201. The other end of the pad 4 extends into the clearance groove 201. The clearance groove 201 facilitates the connection between the pad 4 and the reinforcing plate 2 to form a support, and also facilitates positioning during installation.

[0035] like Figures 1-3 As shown, the tank also includes an end frame 5. A lower connecting plate 6 is provided at each of the two lower corners of the end frame 5. The end cap 1 is fixedly connected to the lower connecting plate 6. The lower connecting plate 6 is an arc-shaped ring that matches the connecting ring 101 and serves as a connection and support. The two lower connecting plates 6 are spaced apart to avoid each other.

[0036] like Figures 1-3As shown, a surrounding plate 9 is fixedly installed on the inner side of each of the two support plates 3. The surrounding plate 9 is fixedly connected to the corresponding lower connecting plate 6. The surrounding plate 9 further enhances the strength of the connecting ring 101 and the support plate 3. The surrounding plate 9 is triangular or trapezoidal.

[0037] The end frame 5 includes a lower end beam 502 and an upper end beam 501 arranged in parallel intervals, and a first corner post 503 and a second corner post 504 respectively arranged vertically at both ends of the lower end beam 502. The lower end of the first corner post 503 is connected to one end of the lower end beam 502 through a first corner piece 505, and the lower end of the second corner post 504 is connected to the other end of the lower end beam 502 through a second corner piece 506. The upper end of the first corner post 503 is connected to one end of the upper end beam 501 through a third corner piece 507, and the upper end of the second corner post 504 is connected to the other end of the upper end beam 501 through a fourth corner piece 508. The support plate 3 is connected to the lower end beam 502 through a liner plate 11, which improves the stress structure of the support plate and enhances the stress-bearing effect.

[0038] like Figure 2 As shown, an upper connecting plate 7 is provided at each of the two corners of the upper part of the end frame 5. An upper horizontal connecting plate 8 is connected between the two lower connecting plates 6. The upper horizontal connecting plate 8 is connected to the inner side of the end frame 5. The upper connecting plate 7 and the upper horizontal connecting plate 8 are connected to form an integral structure. The upper horizontal connecting plate 8 connects the two upper connecting plates 7 together, thereby improving the overall strength.

[0039] like Figure 1 As shown, a reinforcing rib 10 is vertically fixed on the side of the pad 4 away from the cylinder body. The reinforcing rib 10 is fixedly connected to the reinforcing plate 2, and the reinforcing rib 10 strengthens the pad 4.

[0040] like Figure 4 As shown, one of the support plates 3 is provided with a through hole 303 that runs through it in the transverse direction, so as to facilitate the threading of a remote control rope for remote control of the bottom valve.
