DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example: Reference Figure 1-6 The middle side beam structure of a center-flip self-unloading crane door shown in the figure comprises a cargo bucket 1 on which a middle side beam 2 is arranged. The middle side beam 2 is connected to the cargo door through a hinge 3 so that the cargo door can be flipped upward to open when in use.

[0025] In order to prevent the cargo door from flipping downward during its opening, thereby causing a potential safety hazard, in this embodiment, the open cargo door is limited by a limiter 4 to prevent it from flipping and closing.

[0026] Limiter 4: The upper fixer 5 and the lower fixer 6 are fixed on the middle side beam 2 and the cargo door respectively, and the two are connected by an inner shaft 7. The end face of the inner shaft 7 is fixed by bolts. In order to make the inner shaft 7 and the lower fixer 6 rotate coaxially, the fixing hole 61 provided on the lower fixer 6 is adapted to the shaft body 71 of the inner shaft 7. The cross-sections of both are hexagonal. The remaining part of the shaft body 71 is rotatably connected to the rotating hole 51 of the upper fixer 5, and then the rotation angle of the lower fixer 6 is controlled by the limit assembly.

[0027] Limiting assembly: A rectangular hole is provided in the middle of the ratchet 8, and a rectangular fixing head 72 is provided at the end of the shaft body 71. The ratchet 8 is matched with the fixing head 72, so that when the lower fixer 6 rotates, the ratchet 8 is driven to rotate synchronously therewith. A pawl 9 is hinged on the outer wall of the upper fixer 5, and the pawl 9 is matched with the ratchet 8 to limit the flipping angle of the lower fixer 6. In order to keep the state of the pawl 9 at all times, a torsion spring is provided at the connection of the pawl 9.

[0028] A slide groove 11 is provided on the outer wall of the cargo box 1, and a release device 10 adapted to the limiter 4 is provided here, a slider 101 of the release device 10 is slidably connected in the slide groove 11, and the slider 101 is a wedge-shaped block, and a mounting block 102 is provided above the slide groove 11, and a release rod 103 is threadedly connected to the mounting block 102, and the end of the release rod 103 is rotatably connected to the slider 101, so that the release rod 103 rotates, controls the slider 101 to move downward, and cooperates with the pawl 9 of the Z-shaped structure to flip the pawl 9 and release the limit of the ratchet 8.

[0029] The working principle of the utility model is as follows: by releasing the limit between the cargo door and the cargo box 1, and then flipping the cargo door upward, the cargo door is flipped on the middle side beam 2 through the hinge 3 and the limiter 4. During the flipping process, the cargo door rotates on the upper fixture 5 through the lower fixture 6, and the fixing hole 61 is adapted to the shaft body 71 of the inner shaft 7, so that the inner shaft 7 follows the rotation of the lower fixture 6. Then, the rotating inner shaft 7 cooperates with the ratchet 8 through the fixing head 72, driving the ratchet 8 to rotate synchronously. The ratchet 8 cooperates with the pawl 9 on the outer wall of the upper fixture 5 to limit the cargo door in the flipped state and prevent it from flipping down during the flipping process.

[0030] After completing the loading and unloading operations, in order to close the cargo door and facilitate the release of the limit state, the release rod 103 of the release device 10 is rotated so that it can be threadedly rotated on the mounting block 102 and moved downward, so that the slider 101 connected by rotation at the end slides in the slide groove 11. The slider 101 is wedge-shaped, and during its downward movement, the Z-shaped pawl 9 is flipped, thereby releasing the limit on the cargo door and achieving the release of the limit.

Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
