Preferably, the swinging material taking assembly of the embodiment is preferably applied to a ship unloader, the ship unloader extends out of the arm support 12, and the material taking device 100 is mounted on the arm support 12. Specifically, the material taking device 100 is hinged to the arm support 12 through a revolving shaft 103, so that the material taking device 100 can swing around the revolving shaft 103 relative to the arm support 12.

As shown in fig. 3 to 9 and 16 to 17, the upper part of the material taking device 100 is hinged to the pivot shaft 103, so that the material taking device 100 is adapted to swing around the pivot shaft 103. A traction hinge point 206 is arranged at the middle part or the middle lower part of the material taking device 100, the swing mechanism 200 is flexibly connected with the traction hinge point 206, and particularly, the traction rope 202 of the swing mechanism is connected with the traction hinge point 206, so that the material taking device 100 is maintained at a first preset position when no external force is applied; when the material taking device is at the first preset position, the vertical line penetrating through the gravity center of the material taking device 100 and the axis of the rotating shaft 103 are arranged at intervals, and the moment of the material taking device under the action of gravity enables the material taking device to have the tendency of moving towards the land side direction.

When the material taking device 100 moves from the land side to the sea side for operation, the attitude of the material taking device 100 is always kept stable by the tension of the traction steel wire rope.

And when cabin 20 meets the surge condition suddenly, in the ship width direction, if the surge applies force to ship and extracting device 100 towards the sea side direction, extracting device 100 can have a tendency of clockwise swing, at this moment, the force of the surge is applied to extracting device 100, only the pulling force of steel wire rope can be reduced, if the moment of surge force to revolving shaft 103 exceeds the moment of gravity to revolving shaft 103, extracting device 100 slightly swings clockwise, the force of the surge swings, and the force is prevented from being transmitted to the structure of the ship unloader. If the force applied by the surge to the ship and the material taking device 100 is towards the land side direction, the material taking device 100 is subjected to material taking resistance, gravity and steel wire rope tension, and suddenly receives the force of the surge, so that the tension of the steel wire rope can be rapidly increased, the force applied to the pulley at the tail end of the damping oil cylinder can be rapidly increased, when the value exceeds a threshold value, the damping oil cylinder is released, the length of the steel wire rope is increased, and the material taking device 100 swings anticlockwise to achieve a new balance state.

The stroke of the swing mechanism tensioning oil cylinder 201 is large, and the reaction is slow; the stroke of the damping oil cylinder 204 of the swing mechanism is small, and the reaction is fast.

Specifically, the tensioning oil cylinder 201 of the swing mechanism is contracted to increase the included angle between the axis of the material taking device 100 along the length direction and the vertical direction;

the swing mechanism tensioning cylinder 201 extends to reduce the included angle between the axis of the material taking device 100 along the length direction and the vertical direction.

Because hatch department of cabin 20 is provided with the bounding wall, the material that is located the bounding wall below is difficult to be taken out when extracting device 100's normal operating position, consequently, the material subassembly can also drive extracting device 100 and carry out angular adjustment as required to sway that this embodiment provided.
