The invention provides a movable marine anti-rolling platform, which comprises a working platform 19, a movable platform at the bottom, a main hydraulic cylinder 8 filled with hydraulic oil 7 in the middle and a main anti-rolling platform at the upper part as shown in figures 1 to 3, wherein an auxiliary anti-rolling platform is arranged between the movable platform and the main hydraulic cylinder 8.
The auxiliary roll reduction platform comprises an auxiliary guide hydraulic cylinder 5 communicated with the main hydraulic cylinder 8 and a vertical guide plunger 3 which is used for vertically moving in the auxiliary guide hydraulic cylinder 5 under the pressure of ship swing and hydraulic oil 7, and the vertical guide plunger 3 is fixedly connected with the moving platform. In this embodiment, the mobile platform includes walking wheels 1 and an axle 2 connected between the walking wheels 1, and the vertical guide plunger 3 is connected with the axle 2. The walking wheels 1 are in direct contact with the deck of the ship body, and the walking wheels 1 connected through the axles 2 and the vertical guide plungers 3 on the walking wheels are synchronous with the deep movement of the ship body.
The main roll reduction platform comprises 2 main guide hydraulic cylinders 9, the two sides of each main guide hydraulic cylinder 9 are respectively communicated with the main hydraulic cylinder 8, each main guide hydraulic cylinder 9 is provided with 1 horizontal guide plunger 10 used for horizontally moving in the main guide hydraulic cylinder 9, the horizontal guide plungers 10 are connected with roll reduction devices, and the working platform 19 is arranged among the 2 roll reduction devices.
The anti-rolling device comprises a vertical connecting rod connected with a horizontal guide plunger 10, the two ends of the vertical connecting rod are respectively connected with concave bodies 12, the concave surfaces of 2 concave bodies 12 are oppositely arranged and are arc-shaped surfaces, the anti-rolling device also comprises ball bodies 15 fixed at the two ends of the working platform 19, an arc-shaped movable device is connected between the concave surfaces and the ball bodies 15, the arc-shaped movable device comprises an upper arc-shaped movable device and a lower arc-shaped movable device 16 which are symmetrically arranged, the arc-shaped movable device comprises a movable ball 20 capable of sliding on the concave surfaces, an arc-shaped movable sleeve 21 sleeved on the ball body 15 and rotating around the ball body, and a connecting rod 13 connecting the movable ball 20 and the arc-shaped movable sleeve 21; rigid springs, namely an upper rigid spring 14 and a lower rigid spring 17, are connected between the movable ball 20 and the working platform 19.
A plurality of steel balls 18 are arranged between the bottom of the concave body 12 and the main hydraulic cylinder, so that the concave body 12 has good rolling performance, plays a role in supporting the concave body 12 and reduces the friction force in the horizontal direction, and the concave body 12 can timely respond to the horizontal thrust of the hydraulic oil 7.
The tail ends of the main guide hydraulic cylinder 9 and the auxiliary guide hydraulic cylinder 5 are respectively provided with a limiting bulge for limiting the horizontal guide plunger 10 and the vertical guide plunger 3, so that the horizontal guide plunger 10 and the vertical guide plunger 3 can be prevented from being separated from the main guide hydraulic cylinder 9 and the auxiliary guide hydraulic cylinder 5 when the movement distance is larger.
And sealing oil rings 4 are respectively arranged between the horizontal guide plunger 10 and the main guide hydraulic cylinder 9 and between the vertical guide plunger 3 and the auxiliary guide hydraulic cylinder 5. Grooves may be provided in the horizontally and vertically guided plungers 10, 3, and sealing oil rings 4 may be installed in the grooves to prevent leakage of the hydraulic oil 7.
The 2 concave bodies 12 are axially symmetrical along the working platform 19. According to the invention, through the guiding action of the auxiliary guiding hydraulic cylinder 5 and the main guiding hydraulic cylinder 9, the vertical motion of the structure caused by the ship body can be converted into horizontal motion, the hydraulic oil 7 has excellent fluidity and incombustibility, and can absorb energy in the flowing process and attenuate the dynamic response of the structure. The upper arc-shaped movable device and the lower arc-shaped movable device 16 which are composed of the movable ball 20, the connecting rod 13 and the arc-shaped movable sleeve 21 have good sliding performance, and do circular motion around the ball body 15 under the action of external force, so that the structural kinetic energy transmitted to the working platform 19 is further reduced. The upper rigid spring 14 and the lower rigid spring 17 are synchronously stretched and contracted, so that the working platform 19 is always positioned at the axis position in the 2 concave bodies 12.
During the navigation of the ship, the ship body can seriously shake under the action of external force. When the ship body moves upwards under the action of wind and waves, the ship body can drive the walking wheels 1 connected through the axles 2 and the vertical guide plungers 3 on the walking wheels to move vertically upwards at the same time. The vertical upward movement of the vertical guide plunger 3 causes the hydraulic oil 7 to flow into the main hydraulic cylinder 8 through the auxiliary guide hydraulic cylinder 5 and the communicating pipe 6, and causes the two horizontal guide plungers 10 at the two ends to simultaneously approach to the central axis of the vehicle through the horizontal guide function of the main guide hydraulic cylinder 9 and the thrust function of the hydraulic oil. The upper concave body 12 and the lower concave body 12 are rigidly connected with the horizontal guide plunger 10 through a vertical connecting rod, and the motion trail of the upper concave body and the motion trail of the lower concave body are the same as that of the horizontal guide plunger 10. When the two concave bodies 12 move towards the central axis of the whole body of the invention, the upper rigid spring 14 and the lower rigid spring 17 are compressed at the same time, the working platform 19 is still kept at the axial position of the concave body 12, under the thrust action of the concave body 12, the upper arc-shaped movable device 13 and the lower arc-shaped movable device 16 both do circular motion around the ball body 15, and a plurality of steel balls 18 are arranged on the upper surface of the main hydraulic cylinder 8 and the lower surface of the concave body 12, support the concave body 12 and reduce the friction force in the horizontal direction. When the vertical guide plunger 3 moves upwards, the kinetic energy transferred to the working platform can be gradually attenuated through the flow of the hydraulic oil 7, the horizontal movement of the concave body 12, the rotation of the arc-shaped movable device and the compression of the rigid spring, so that the movement amplitude of the working platform is greatly reduced. When the ship moves downwards under the action of wind and waves, the working principle of the invention is opposite, but the working platform 19 is still kept at the central axis position of the concave body 12, so the device can effectively reduce the shaking amplitude of the structure at the local position of the ship body when the ship shakes.
The novel movable ship anti-rolling platform is arranged at the local position of a ship in a gradually weakening mode, so that the lifting amplitude of the working platform caused by deep motion of the ship is compensated, and the swing amplitude of the working platform can be effectively reduced. The dynamic effect of the ship shaking on the platform is further attenuated by the circular motion of the arc-shaped movable devices and the arc-shaped movable devices at the lower part, so that the shaking amplitude of the working platform is smaller when the ship shakes.
The device has the advantages of simple structure, strong practicability and lower cost, the anti-rolling platform can be arranged at a special position where the ship needs to be anti-rolled according to the design principle, wheels are arranged at the bottom of the anti-rolling platform, the anti-rolling platform has mobility, and workers can perform related work on the anti-rolling platform, so that the anti-rolling platform is wide in application.
