The number of the twistlocks 421 may be plural, and is generally four, and four twistlocks 421 correspond to four vertex parts of the container 5 one by one. The lock driver 422 may actuate two of the tumblers 421 at the same time, or actuate four of the tumblers 421 at the same time.

As shown in fig. 1, a corner fitting 54 is disposed at a vertex of the container 5, the corner fitting 54 has a rectangular parallelepiped structure, a cavity is disposed inside the corner fitting 54, a waist-shaped hole communicated with the cavity is disposed on a side wall of the corner fitting 54, based on the structure of the corner fitting 54, as shown in fig. 9 and 10, the locking device 421 includes a locking rotation shaft 421a, the locking rotation shaft 421a is rotatably disposed on the box hanger 41, and a locking hook 421b capable of extending into the corner fitting 54 is disposed at one end of the locking rotation shaft 421 a; the locking actuator 422 includes a locking expansion piece 422a, a push-pull rod 422b and a swing rod 422c, the locking expansion piece 422a is disposed on the box hanger 41, the swing rod 422c is radially disposed on the locking rotation shaft 421a, and two ends of the push-pull rod 422b are movably connected to the locking expansion piece 422a and the swing rod 422c, respectively.

For example, when the first knock pin 332 abuts against the first acting end, the door pressing rotating shaft 531 rotates to a certain angle towards the preset rotating direction, and the door pressing hook 532 hooks the side edge of the door 52 away from the hinge edge towards the opening of the box body 51 under the driving of the door pressing rotating shaft 531, so that the door 52 is tightly pressed on the opening of the box body 51; when the second knock pin 333 abuts against the second acting end, the door pressing rotating shaft 531 rotates at a certain angle in a direction opposite to the predetermined rotating direction, and the door pressing hook 532 is driven by the door pressing rotating shaft 531, so that the door pressing hook 532 is away from the side of the door 52, and the door 52 is no longer pressed against the opening of the box 51.

As shown in fig. 6 and 7, in order to enable the lifting frame 22 to support the roll-over stand 31, the fixing frame 21 comprises a supporting column 211 arranged on the berth base 1; the lifting frame 22 comprises a sliding column 221 in sliding fit with the supporting column 211, a roll-over stand holder 222 arranged at the top of the sliding column 221 and an assembly connecting frame 223 for hinging the roll-over stand 31. Further, the rollers can be arranged between the supporting column 211 and the sliding column 221, and the wear-resisting plates can also be arranged, so that the friction force and the wear degree between the supporting column 211 and the sliding column 221 are reduced, and the movement stability of the lifting frame 22 is improved.

For example, when the container 5 is turned from a horizontal state, the auxiliary telescopic devices 62 can increase the initial turning thrust acting on the turning frame 31, so that the initial turning tension acting on the turning frame 31 by the main telescopic devices 61 is compensated; since one end of the auxiliary retractor 62 abuts against the roll-over stand 31, the one end of the auxiliary retractor 62 is separated from the roll-over stand 31 after the auxiliary retractor 62 is gradually extended to the maximum stroke. On the contrary, when the container 5 is turned over from the standing state, when the center of gravity of the container 5 passes right above the turning center line of the turning frame 31, the main telescopic device 61 is changed from the turning thrust acting on the turning frame 31 to the turning tension acting on the turning frame 31 under the action of the gravity of the container 5, so that the container is stalled instantaneously, even the main telescopic device 61 is damaged, and the container falls down and other major accidents occur. At this time, one end of the auxiliary telescopic device 62 abuts against the roll-over stand 31, and pushes the roll-over stand 31 while contracting, so that the container 5 is dragged to be smoothly rolled over to a horizontal state, thereby avoiding instantaneous stall and well protecting the main telescopic device 61.

When the deviation is corrected, the tires of the transport vehicle move on the corresponding deviation correcting roller paths 12, so that the resistance is small, the tires are not damaged, and the position precision is high.

Further, the centering device 13 includes a base 131, a double-headed driver 132 and two pushing rods 133, the base 131 is disposed in the middle of the two deviation rectifying raceways 12, two telescopic ends of the double-headed driver 132 are disposed in a back-to-back manner, the two pushing rods 133 and the two telescopic ends correspond to each other, and each pushing rod 133 is disposed at the corresponding telescopic end and is in abutting fit with a wheel of the transport vehicle.
