The first ball 13, the ball seat 17, the connecting shaft 16, the taper chuck 15, and the second ball 14 are located on the same axis.
As shown in fig. 1, the second ball head 14 is used to make the connection and roll in a ball seat 17 with a conical groove or cage-shaped pawl 5 to release three rotational degrees of freedom. As shown in fig. 2, the engagement of the tapered chuck 15 and the tapered socket 17 is used to release the rotation of the ball hook 4 in the width direction and the height direction when the ball hook 4 is in the extended state (i.e. when the tapered chuck 15 is disengaged from the tapered socket 17), and to limit the rotation of the ball hook 4 in the width direction and the height direction when the ball hook is in the retracted state (i.e. when the tapered chuck 15 is engaged in the tapered socket 17), so that the second ball 14 is kept in a state of no relative movement with the second hull 2, so as to facilitate the hitching operation of the second hull 2.
As shown in fig. 1, the connecting shaft 16 is used for connecting the second ball head 14 and the tapered chuck 15 and can slide in the ball seat 17 with a tapered slot.

As shown in fig. 6, when two ships are in a connected state, if sudden conditions such as rapid resistance increase of the second ship body 2 occur, the traction force of the first ship body 1 is too large, the pressure of the oil cylinder 8 is increased, at the moment, the overflow valve 10 starts oil drainage, the oil cylinder 8 moves towards the stern, the cage-shaped claw 5 is opened, the second bulb 14 is released, and the second ship body 2 is separated from the first ship body 1, so that the cage-shaped hitching structure 3 is protected from overload damage.
Therefore, the device can restrain the relative longitudinal or transverse motion between the fore ship and the aft ship, but basically does not restrain the relative vertical motion and the rotation of the fore ship and the aft ship in each axial direction; meanwhile, the device has the capability of fast hanging or releasing and also has the capability of automatic releasing during overload
In conclusion, the device can realize free swinging angle in a range of approximately a hemispherical surface in a ball cage type connection mode; the relative position change in a certain range is realized by utilizing the swinging of the connecting rod in the swing angle range in a mode of reserving the connecting rod with a certain length, so that the buffering effect is achieved; meanwhile, the front ship adopts an openable cage type structure to realize the connection and release of the spherical connector; the rear boat adopts a telescopic rod-shaped structure to realize the motion constraint and release of the spherical connector. The device also has the capacity of automatic release during overload, can realize effective connection between ships, and simultaneously releases the axial rotation freedom degree which has adverse effect on the movement between the ships; in addition, the hanging scheme of the device is easy to align, the difficulty is reduced for hanging operation, and the hanging success rate is high; moreover, the implementation of the releasing scheme is quick, and the formation quick switching is convenient; moreover, the connecting device can be automatically released when being overloaded, and the possibility of equipment damage is reduced.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
