[0023] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0024] refer to Figures 1 to 5 The embodiment of the present application provides a hydraulic rollover self-unloading container, comprising a container frame 10 and a container body 20 disposed in the container frame 10. A hydraulic cylinder 12 is installed in the base 11 of the container frame 10 directly below the container body 20. The telescopic shaft 121 of the hydraulic cylinder 12 is connected to the container body 20 in an articulated manner, so that the container body 20 can be lifted by extending and retracting the telescopic shaft 121. A plurality of side doors 21 are symmetrically arranged on both sides of the box body 20, wherein the top of the side door 21 is hinged to the top of the box body 20, wherein the top of the side door 21 can be hinged to the top of the box body 20 by a hinge structure 211. In addition, a baffle 22 is arranged at the bottom of the side door 21, and a locking notch 201 which can extend to the outside of the base 11 is opened at the bottom of the baffle 22. Correspondingly, an L-shaped hook 13 is arranged in the locking notch 201 of the base 11, wherein the horizontal portion 131 of the L-shaped hook 13 extends horizontally to the outside of the locking notch 201, and the vertical portion 132 of the L-shaped hook 13 extends vertically upward on the outside of the locking notch 201. In addition, the bottom plate 23 of the box body 20 is hinged to the base 11 by pins 231 on both sides, so that the box body 20 can be firmly fastened to the box frame 10 by the pins 231 when the side door 21 does not need to be opened.

[0025] The key point is that the base 11 is provided with a locking frame 14 that cooperates with the L-shaped hook 13. This cooperation relationship enables the locking frame 14 to automatically hook into the L-shaped groove 101 of the L-shaped hook 13 with external force to lock the baffle 22. For example, the staff manually (i.e., external force) hooks the locking frame 14 on the vertical part 132, and then automatically hooks the locking frame 14 into the L-shaped groove 101. At the same time, this cooperation relationship can also enable the locking frame 14 to be driven and automatically disengaged from the vertical part 132 to unlock the baffle 22. In this way, when the telescopic shaft 121 is extended to use the pin shaft 231 as the hinge axis to flip the box body 20 to a predetermined angle, the side door 21 can be automatically opened under gravity.

[0026] More specifically, when unloading on the left side of the container, the pin shaft 231 on the right side of the box body 20 is first removed. At this time, the right side door 21 is kept in a state of being locked by the right locking frame 14. Then, the left locking frame 14 is driven to automatically disengage from the left vertical portion 132 and unlock the corresponding baffle 22. Then, the hydraulic cylinder 12 moves to lift the box body 20 through the telescopic shaft 121. Under the action of the pin shaft 231 between the bottom plate 23 of the left box body 20 and the base 11 as a rotating hinge shaft, the right side of the box body 20 will rise, and the left side of the box body 20 will gradually tilt downward. The left side door 21 will automatically open under its own weight to complete the self-unloading. Therefore, when self-unloading is required, the side door 21 can be automatically unlocked by the locking frame 14, thereby avoiding manual unlocking and opening of the side door 21, thereby avoiding heavy bulk cargo breaking through the restraint of the side door 21 and suddenly rushing out to bury the workers' feet and dirty the workers. At the same time, it can also greatly reduce the safety hazards to workers during self-unloading.

[0027] In one embodiment, the bottom of the bottom plate 23 is provided with an air chamber 15 and a first connecting rod 16, wherein the air inlet of the air chamber 15 is connected to the gas cylinder or gas bottle of the vehicle, so that the vehicle can be directly used as a power source to provide gas power, which is more convenient to use. The piston rod 151 of the air chamber 15 extends obliquely downward away from the bottom plate 23. The first connecting rod 16 is hinged to the bottom plate 23 near the middle, and one end of the first connecting rod 16 is hinged to the piston rod 151, and the other end of the first connecting rod 16 is hinged to the locking frame 14. In this way, a three-link structure α can be formed by the piston rod 151, the first connecting rod 16 and the locking frame 14. When the piston rod 151 of the air chamber 15 is extended, the piston rod 151 pushes the first connecting rod 16 to gradually tilt upward with the hinge point between the first connecting rod 16 and the bottom plate 23 as the rotation axis, so that the locking frame 14 can move upward along the vertical portion 132, and then gradually disengage from the L-shaped groove 101, thereby completing the unlocking of the baffle 22. When the box body 20 is lifted by the hydraulic cylinder 12, the baffle 22 will be automatically opened together with the side door 21 based on the clearance fit between the locking notch 201 and the L-shaped hook 13.

[0028] In one embodiment, the locking frame 14 is a U-shaped structural member. The end of the first connecting rod 16 is inserted into the opening of the locking frame 14 and is hinged with the locking frame 14 through the locking pin 17, which is not only convenient for assembly, but also makes it easier for the locking frame 14 to be sleeved on the vertical portion 132.

[0029] In order to firmly fix the side door to prevent it from being opened during transportation of the container, in one embodiment, there are multiple baffles 22, and the multiple baffles 22 are distributed in sequence along the extension direction of the side door 21, so that a multi-point fixing structure can be formed at the bottom of the side door 21 based on the matching relationship between the baffles 22, the L-shaped hooks 13 and the locking frame 14.

[0030] In one embodiment, the box frame 10 further includes side frames 18 located on both sides of the box body 20 and extending vertically. The two side frames 18 are symmetrically installed with side door locks 19 near the lower part of the box body 20, and the box body 20 is installed with side door pins 24 extending horizontally and cooperating with the two side door locks 19, thereby further improving the firmness of the side door 21. When self-unloading is required, the side door pins 24 can be manually unlocked first, and the side door 21 is still fixed by the locking frame 14 at this time, so there is no risk of leakage.

[0031] In one embodiment, the length of the box frame 10 is 9000 mm, 10000 mm, 11000 mm, 12000 mm or 13000 mm, the width of the box frame 10 is 2500 mm or 2550 mm, and the height of the box frame 10 is 1600 mm, 1800 mm or 2000 mm.

[0032] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
