When the shore crane trolley moves forward and backward, the spreader will swing greatly, and the spreader cannot be well aligned with the stationary container, so it is mostly relied on the driving experience to control the trolley movement speed and use inertia to stop the swing, but the spreader often rotates in multiple directions, and cannot be quickly stopped by operation, so the container matching problem in the operation process of the shore crane needs to be optimized.

[0033] The working principle of one embodiment of the present application is as follows: when the present application works, the angular velocity and angular acceleration of the hoist 4 swinging are obtained by the angular velocity sensor and the angular acceleration sensor on the hoist 4, and the data are analyzed by the total control system 2, the rotational inertia of the hoist 4 and the hoist superstructure 3 system multiplied by the swinging angular acceleration is equal to the rotational inertia of the flywheel 10 multiplied by the angular acceleration of the flywheel 10, the data are obtained, the horizontal rotary flywheel 6, the longitudinal flywheel 7 and the transverse flywheel 8 are driven by the respective motors to rotate in the same direction as the rotation direction of the hoist 4 with a certain angular acceleration, the rotational inertia of the horizontal rotary flywheel 6, the longitudinal flywheel 7 and the transverse flywheel 8 multiplied by the angular acceleration can obtain the resultant external moment of the horizontal rotary flywheel 6, the longitudinal flywheel 7 and the transverse flywheel 8, the external force of the horizontal rotary flywheel 6, the longitudinal flywheel 7 and the transverse flywheel 8 is all provided by the respective motors, while the A motor 12, the B motor 14 and the C motor 16 are fixed on the flywheel machine frame 5, the longitudinal flywheel mounting frame 9 and the transverse flywheel mounting frame 10 respectively, in fact, the flywheel machine frame 5, the longitudinal flywheel mounting frame 9 and the transverse flywheel mounting frame 10 will receive the moment which is equal in size and opposite in direction to the moment received by the horizontal rotary flywheel 6, the longitudinal flywheel 7 and the transverse flywheel 8, the flywheel machine frame 5 is fixed on the hoist superstructure 3, and the flywheel machine frame 9 will finally transmit the moment to the hoist superstructure 3; therefore, the rotational moment of the horizontal rotary flywheel 6, the longitudinal flywheel 7 and the transverse flywheel 8 finally acts on the hoist 4, balances the rotational moment of the hoist 4 caused by the external force, and realizes the purpose of preventing the hoist 4 from swinging;
[0034] From the whole, the disturbance of the outside to the hoist 4 and the hoist superstructure 3 as a whole is equivalent to that the outside gives the hoist 4 and the hoist superstructure 3 a moment, the product of the moment and time is the increment of the angular momentum of the system, if there is no rotation of the horizontal rotary flywheel 6, the longitudinal flywheel 7 and the transverse flywheel 8, the increment of the angular momentum will be manifested as the rotation of the hoist 4, but now there is the rotation of the horizontal rotary flywheel 6, the longitudinal flywheel 7 and the transverse flywheel 8, as far as the hoist 4 and the hoist superstructure 3 are concerned, the angular momentum should be conserved under the condition of no external force, but now the angular momentum of the horizontal rotary flywheel 6, the longitudinal flywheel 7 and the transverse flywheel 8 has an increment, the angular momentum increment of the horizontal rotary flywheel 6, the longitudinal flywheel 7 and the transverse flywheel 8 is equal to the product of the external moment and time, which is equal to that the disturbance of the outside only causes the rotation of the horizontal rotary flywheel 6, the longitudinal flywheel 7 and the transverse flywheel 8.
