[0040] like Figure 1 to Figure 6 As shown, this embodiment provides a ring beam structure, which includes a first support beam 1, an upper cross beam 3 and two second support beams 2.

The first support beam 1 and the two second support beams 2 of the ring beam structure are all castings manufactured by a casting process, so they have a simple structure, fewer welds, and high processing accuracy. One end of the two second support beams 2 is plugged into the two ends of the first support beam 1 in a one-to-one correspondence, and the two second support beams 2 are respectively fixedly connected to the two ends of the first support beam 1. This arrangement can improve the assembly accuracy between the first support beam 1 and the two second support beams 2 on the one hand, and improve the fixing strength between the first support beam 1 and the two second support beams 2 on the other hand. Therefore, the ring beam structure has the advantages of simple structure, high processing accuracy, high overall strength and high processing efficiency.

[0041] Specifically, the first support beam 1 and the two second support beams 2 are fixed to each other through a welding process.

[0042] In the prior art, the main and secondary longitudinal beams 200 are usually directly welded to the ring beam structure. In order to improve the connection strength between the main longitudinal beam 100 and the secondary longitudinal beam 200 and the ring beam structure, the second support beam 2 optionally includes a body 21 and a first connection portion 22 and a second connection portion 23 protruding on both sides of the body 21 along the second horizontal direction Y. The first connection portions 22 of the two second support beams 2 are used to be plugged in with the corresponding main longitudinal beam 100 and fixed to each other. The second connection portions 23 of the two second support beams 2 are used to be plugged in with the corresponding secondary longitudinal beam 200 and fixed to each other. The first horizontal direction X and the second horizontal direction Y are perpendicular. In this embodiment, the first connection portion 22 is plugged in with the corresponding main longitudinal beam 100, and then the first connection portion 22 and the main longitudinal beam 100 are fixed to each other. This setting can improve the strength of the second support beam 2 connecting the main longitudinal beam 100. Specifically, the first connection portion 22 and the main longitudinal beam 100 are fixed to each other by welding. In other embodiments, the first connection portion 22 and the main longitudinal beam 100 can also be screwed to each other. The connection method between the second connection portion 23 and the secondary longitudinal beam 200 is the same as the connection method between the first connection portion 22 and the main longitudinal beam 100 . Therefore, the effects produced are also the same and will not be described in detail herein.

[0043] Optionally, the first connecting portion 22 includes a first support plate 221 and a second support plate 222 arranged at intervals along the vertical direction Z, the first support plate 221, the second support plate 222 and the main body 21 are arranged to form a first U-shaped groove, the main longitudinal beam 100 is inserted into the corresponding first U-shaped groove, and the first support plate 221 and the second support plate 222 are respectively abutted against the main longitudinal beam 100; the second connecting portion 23 includes a third support plate 231 and a fourth support plate 232 arranged at intervals along the vertical direction Z, the third support plate 231, the fourth support plate 232 and the main body 21 are arranged to form a second U-shaped groove, the secondary longitudinal beam 200 is inserted into the corresponding second U-shaped groove, and the third support plate 231 and the fourth support plate 232 are respectively abutted against the secondary longitudinal beam 200. In this embodiment, taking the first connecting portion 22 as an example, since the main longitudinal beam 100 is mainly subjected to the gravity in the vertical direction Z, the first support plate 221 and the second support plate 222 are arranged at intervals along the vertical direction Z, and then when the main longitudinal beam 100 is inserted into the first U-shaped groove, the first support plate 221 and the second support plate 222 support the main longitudinal beam 100 along the vertical direction Z. The above arrangement can improve the connection strength between the second support beam 2 and the main longitudinal beam 100. The second connecting portion 23 has the same structure as the first connecting portion 22, which will not be repeated here.

[0044] Optionally, the first connection portion 22 further includes a first plug-in portion 223, the first plug-in portion 223 is located between the first support plate 221 and the second support plate 222, and the first plug-in portion 223 is used to be inserted into the corresponding main longitudinal beam 100 and to abut against the inner wall of the corresponding main longitudinal beam 100; the second connection portion 23 further includes a second plug-in portion 233, the second plug-in portion 233 is located between the third support plate 231 and the fourth support plate 232, and the second plug-in portion 233 is used to be inserted into the corresponding secondary longitudinal beam 200 and to abut against the inner wall of the corresponding secondary longitudinal beam 200. In this embodiment, the first plug-in portion 223 can further improve the connection strength between the main longitudinal beam 100 and the corresponding second support beam 2. At the same time, the welding area between the main longitudinal beam 100 and the first connection portion 22 can also be increased.

In this embodiment, since the first support plate 221 is subjected to the greatest pressure from the main longitudinal beam 100 in the direction of gravity, it is necessary to increase the strength of the first support plate 221, and thus a first reinforcing rib 224 is provided between the side of the first support plate 221 away from the second support plate 222 and the main body 21; the third support plate 231 is subjected to the greatest pressure from the secondary longitudinal beam 200 in the direction of gravity, it is necessary to increase the strength of the third support plate 231, and thus a second reinforcing rib 234 is provided between the side of the third support plate 231 away from the fourth support plate 232 and the main body 21; the fourth support plate 232 is subjected to the pressure from the secondary longitudinal beam 200 in the opposite direction of gravity, so it is necessary to increase the strength of the fourth support plate 232, and thus a third reinforcing rib 235 is provided between the side of the fourth support plate 232 away from the third support plate 231 and the main body 21.

[0046] Optionally, a fourth reinforcing rib 225 is provided between one side of the first plug-in portion 223 and the body 21 along the first horizontal direction X. In this embodiment, the fourth reinforcing rib 225 can prevent the first plug-in portion 223 from deforming along the first horizontal direction X, thereby preventing the second support beam 2 and the main longitudinal beam 100 from deforming at the connection position.

[0047] Optionally, the upper cross beam 3 is a box-shaped structure. In this embodiment, the purpose of setting the upper cross beam 3 to be box-shaped is to facilitate the installation and positioning of other components.
