The working principle of the invention is as follows: as shown in figure 1, when the box door is opened, if the speed is too high, the box door rotates around a shaft, the piston rod I3 is pushed by the connecting rod 2 to rapidly move towards the left side inside the hydraulic cylinder I11 under the guiding action of the guide sleeve I13, the piston plate I12 is pushed to rapidly push the liquid inside the hydraulic cylinder I11, the liquid inside the hydraulic cylinder I11 is rapidly compressed, the pressure inside the high-pressure cavity at the left side of the piston plate I12 is suddenly increased, the high-pressure liquid overflows into the limiting cylinder 5 from the overflow pipe 4, so that the pressure inside the limiting cylinder 5 is also increased, as shown in figure 2, after the pressure inside the limiting cylinder 5 is increased, the liquid pushes the piston plate III 18 to drive the rack I14 to synchronously move left, so that the rack I14 drives the gear I15 to rotate, the gear I15 drives the disc plate 17 to synchronously rotate through the valve rod 16 while the gear I15 rotates, so that the flow of the butterfly valve 10 is reduced or the butterfly valve 10 is closed, the left movement of the piston rod I12 is limited, so that the speed limitation or stop of the box door is realized, and the safety of the box door when the box door is opened is ensured;

after the box door rotates reversely for a certain angle, the connecting rod 2 pulls the piston rod I3 to move right, the piston plate I12 is synchronously driven to move right to reduce the pressure in the hydraulic cylinder 11 and the limiting cylinder 5, the piston plate III 18 is pushed to move right under the action of the spring I19, and the rack I14 is synchronously driven to move right, so that the rack I14 drives the gear I15 to rotate reversely, the valve rod 16 drives the disc plate 17 to open, the liquid flows smoothly, and the box door can be opened;

if the opening of the box door is slow at a constant speed, the box door pushes a piston plate I12 to extrude liquid in a hydraulic cylinder I11 at a constant speed through a connecting rod 2 and a piston rod I3, the increase amplitude of the pressure in the hydraulic cylinder I11 is small, the pressure difference value in a limiting cylinder 5 is small, a spring I19 has reverse acting force which is enough to overcome the increase amplitude of the pressure in the limiting cylinder 5, and along with the slow increase of the pressure in the hydraulic cylinder I11, the liquid flows to a hydraulic cylinder II 9 from a butterfly valve 10, so that the uniform-speed safe opening of the box door is realized;

as shown in fig. 2 and 3, after the door is opened at a certain angle, the liquid in the hydraulic cylinder I11 flows into the hydraulic cylinder II 9, the piston plate II 6 is pushed to move to the left by a distance corresponding to the distance of one end, the piston plate II 6 moves to the left while driving the rack II 7 to move to the left synchronously, the rack II 7 moves to the left while driving the gear II 82 to rotate clockwise, at the moment, the limit block 86 does not limit the gear II 82 and the rack II 7, but when the rack II 7 moves to the right, the gear II 82 is driven to rotate anticlockwise, at the moment, the limit block 86 limits the gear II 82 and the rack II 7 under the action of the spring II 85, so that the rack II 7 cannot move to the right, the door is prevented from being closed under the action of external force after being opened, and then goods can be;

when the box door is required to be closed, the limiting block 86 is pushed leftwards to enable the limiting block 86 to be separated from the second gear 82 and not to be in contact with the second gear, the limiting block 86 does not have a limiting effect on the space between the second gear 82 and the second rack 7, the box door rotates reversely, the first piston rod 3 and the first piston plate 12 are pulled by the box door through the connecting rod 2 to move rightwards synchronously, the internal pressure of the first hydraulic cylinder 11 is reduced and the effect of internal and external pressure difference is utilized, liquid inside the second hydraulic cylinder 9 enters the first hydraulic cylinder 11 through the butterfly valve 10, after the liquid inside the second hydraulic cylinder 9 is transferred, the pressure is reduced, the second piston plate 6 drives the second rack 7 to move rightwards synchronously to reset under the effect of the external pressure, the.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention.
