Description

Technical Field

[0001] The utility model relates to the technical field of ship platforms, in particular to a novel mobile ship anti-rolling platform. Background Art

[0002] Mobile ship anti-roll platform is a device specially designed for use on ships. Its main function is to reduce the shaking and bumping caused by waves when the ship is sailing on the sea, thereby providing a stable working platform. This type of structure includes components such as hydraulic cylinders, dampers, sensors and controllers. These components can sense the changes in the ship's posture, and then adjust the working state of the hydraulic cylinder in time to generate opposite forces to offset the shaking of the hull.

[0003] For example, the mobile ship anti-rolling platform disclosed in the authorization announcement number CN107499470B includes a mobile platform at the bottom, a main hydraulic cylinder filled with hydraulic oil in the middle, and a main anti-rolling platform at the top, and an auxiliary anti-rolling platform is arranged between the mobile platform and the main hydraulic cylinder; the auxiliary anti-rolling platform includes an auxiliary guide hydraulic cylinder connected to the main hydraulic cylinder, and a vertical guide plunger used to move vertically in the auxiliary guide hydraulic cylinder under the swaying of the ship and the pressure of the hydraulic oil, and the vertical guide plunger is fixedly connected to the mobile platform; the main anti-rolling platform includes two main guide hydraulic cylinders connected to the main hydraulic cylinder on both sides, each of which is equipped with a horizontal guide plunger used to move horizontally in the main guide hydraulic cylinder, and its working platform is arranged between the two anti-rolling devices to reduce the swaying amplitude of the working platform. However, the technical solution mainly reduces the swaying of the platform in the horizontal left and right directions, and when the ship is sailing on the sea, the waves and wind force it is subjected to will also cause the hull to sway in the front and rear directions. In the case of poor sea conditions, it is difficult for the anti-rolling platform to provide a sufficiently stable working environment, thereby affecting the work on the ship and the safety of the staff.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4 The utility model provides an embodiment: a novel mobile ship anti-rolling platform, including a support platform 1, two support platforms 1 are provided, and the main hydraulic cylinder 6 and the auxiliary hydraulic cylinder 7 are symmetrically hingedly installed on the outer walls of the two support platforms 1 on the side away from each other. The extension lines of the cylinder bodies of the main hydraulic cylinder 6 and the auxiliary hydraulic cylinder 7 are V-shaped, and the top of the support platform 1 is rotatably installed with a main shaft 4, and the opposite ends of the two main shafts 4 are fixed with an I-shaped frame 8, and the ends of the two main shafts 4 away from each other are fixed with a triangular plate 5, and the surface of the triangular plate 5 is provided with an arc-shaped hollow groove, and the top ends of the piston rods of the main hydraulic cylinder 6 and the auxiliary hydraulic cylinder 7 are hinged to each other at the bottom corners of the triangular plate 5;

[0019] A circular outer frame 9 is installed on the outer walls of both sides of the I-shaped frame 8, and a longitudinal axis 10 is rotatably installed on the front and rear inner walls of the circular outer frame 9. A platform monomer 11 is installed between the two longitudinal axes 10. The front and rear inner walls of the platform monomer 11 are both provided with inner grooves. One end of the longitudinal axis 10 extends into the inner groove and is fixedly connected to the platform monomer 11.

[0020] A longitudinal anti-roll structure 12 and a longitudinal anti-roll structure 2 13 are respectively arranged on both sides of the bottom end of the circular outer frame 9 for contacting the corner positions of the bottom end of the platform monomer 11. A level sensor 14 is installed at the center position of the bottom end of the platform monomer 11. A control panel 2 is installed on one side inside the support platform 1. The output end of the control panel 2 is electrically connected to the input end of the main hydraulic cylinder 6 and the auxiliary hydraulic cylinder 7. The output end of the level sensor 14 is electrically connected to the input end of the control panel 2.

[0021] When suppressing the front and rear pitching swing of the circular outer frame 9 and the platform unit 11, the main hydraulic cylinder 6 and the auxiliary hydraulic cylinder 7 actively control the swing angles of the main shaft 4, the triangular plate 5, the circular outer frame 9 and other components, so that the horizontal value detected by the horizontal sensor 14 is in a balanced state. Since hydraulic cylinders are arranged on the outer walls of the two support platforms 1, even if one of the components fails, the other component can still continue to work, thereby ensuring the normal operation of the anti-roll platform, thereby improving the redundancy of the platform;

[0022] An upper shaft cylinder 3 is fixed on the top of the support platform 1, and the main shaft 4 is rotatably installed inside the upper shaft cylinder 3. Both ends of the main shaft 4 penetrate the outside of the upper shaft cylinder 3. The upper shaft cylinder 3 ensures that the main shaft 4 will not produce excessive vibration or deformation during operation, thereby ensuring the operation stability of the entire equipment;

[0023] The triangle plate 5 and the I-shaped frame 8 are both made of aluminum alloy. Aluminum alloy has excellent corrosion resistance and can resist the erosion of the components by environmental factors such as seawater and air, thereby extending the service life of the triangle plate 5 and the I-shaped frame 8.

[0024] The longitudinal anti-roll structure 13 includes a bending plate 1301 installed on one side of the bottom end of the circular outer frame 9, and the front and rear outer walls of the bending plate 1301 are fixed with double-layer arms 1302, and a damping shock absorber 1303 is hinged on the outer wall of one side of the double-layer arm 1302, and a U-shaped support seat 1305 is hinged on the top of the damping shock absorber 1303. A double pull rod 1304 is hinged on the outer wall of one side of the double-layer arm 1302, and the top of the double pull rod 1304 is hinged to the outer wall of one side of the U-shaped support seat 1305. A connecting foot 1306 is installed at the corner position of the bottom end of the platform monomer 11, and the bottom end of the connecting foot 1306 and the top of the U-shaped support seat 1305 are hinged to each other;

[0025] In response to the left and right ups and downs of the platform unit 11, the platform unit 11 will rotate and swing with the longitudinal axis 10 as the center. At this time, since the platform unit 11 is hinged through the connecting foot 1306 and the U-shaped support seat 1305, the corners of the platform unit 11 will apply downward pressure to the connecting foot 1306, the U-shaped support seat 1305 and the double pull rod 1304. At this time, the double pull rod 1304 swings, and the damping shock absorber 1303 reduces the vibration amplitude of the platform unit 11 during the ups and downs, thereby reducing the impact force on the platform and working equipment.

[0026] When the embodiment of the present application is used, the anti-rolling platform is first moved to the area to be used, so that the connection line between the two support platforms 1 is parallel to the horizontal X-axis line, and the connection line between the main hydraulic cylinder 6 and the auxiliary hydraulic cylinder 7 is parallel to the horizontal Y-axis line. At this time, the horizontality of the platform monomer 11 is detected by the horizontal sensor 14. At this time, when the ship and the platform are shaken and bumped by waves, the longitudinal anti-rolling structure 1 12 and the longitudinal anti-rolling structure 2 13 suppress the left and right ups and downs of the platform monomer 11, so that the platform monomer 11 remains relatively stable in the horizontal left and right directions, and for the pitching swing in the front and rear directions, the main hydraulic cylinder 6 and the auxiliary hydraulic cylinder 7 are adjusted according to the pitching swing in the front and rear directions. The feedback signal of the horizontal sensor 14 adjusts its working state in real time to respond quickly and accurately to the posture changes of the platform unit 11 and the circular outer frame 9 in the front and rear directions, so as to achieve a precise anti-roll effect. In this process, the main hydraulic cylinder 6 and the auxiliary hydraulic cylinder 7 have opposite actions, that is, the main hydraulic cylinder 6 extends and retracts to push the triangle plate 5, the main shaft 4 and the circular outer frame 9 to swing, and the auxiliary hydraulic cylinder 7 contracts to cope with the shaking of the platform in the front and rear directions. In this way, when the ship is sailing on the sea, it can not only maintain relative stability in the horizontal left and right directions, but also effectively reduce the shaking in the front and rear directions, providing a more stable working environment.
