Description

Technical Field

[0001] The invention relates to the technical field of gyro anti-roll device, and in particular to a buffer structure of a precession system of a gyro anti-roll device. Background Art

[0002] The gyro anti-roll device is a device that uses the precession characteristics of the gyro to form a stabilizing torque to reduce the sway of the ship and improve its seaworthiness. The gyro rotor, as the core component of the gyro anti-roll device, is a component driven by an external force and has been dynamically balanced and rotated at high speed. When a surface ship equipped with a gyro anti-roll device is impacted by waves, the gyro anti-roll device uses the precession characteristics of the gyro to form a stabilizing torque in the opposite direction to the wave impact. In this process, the control of the precession speed and precession angle of the gyro rotor is the core technology of the gyro anti-roll device control.

[0003] The existing control of the precession speed and precession angle of the gyro rotor is controlled by a hydraulic system. When the gyro rotor precesses to the ends on both sides, the precession torque of the hydraulic system on the gyro rotor decreases significantly due to the change in the rotation angle. In order to better control the precession angle and precession speed, the working pressure of the hydraulic system has to be increased. The increase in the working pressure of the hydraulic system increases the equipment cost and reduces the overall life of the hydraulic system. Summary of the invention

[0004] In view of the above-mentioned shortcomings that currently exist, the present invention provides a buffer structure for the precession system of a gyro anti-roll device. By adding a collision block to the gyro rotor, a buffer is used at the precession end of the gyro rotor to control the precession speed and precession angle of the gyro rotor, thereby greatly improving the control of the gyro anti-roll device over the precession torque at the precession end of the gyro rotor, reducing the working pressure of the hydraulic system, increasing the service life of the hydraulic system, and reducing the equipment cost. At the same time, the overall structure is simple, easy to disassemble, manufacture and process, and has low cost.

[0005] To achieve the above object, the embodiments of the present invention adopt the following technical solutions:

[0006] The buffer structure of the precession system of the gyro anti-roll device comprises a base, wherein the base is used to install a gyro rotor that precesses and swings laterally. The buffer structure of the precession system of the gyro anti-roll device also comprises a first mounting seat, a second mounting seat, a first buffer, a second buffer, and a collision block. The first mounting seat and the second mounting seat are respectively fixed on the base, the first buffer and the second buffer are respectively correspondingly installed on the first mounting seat and the second mounting seat, and the collision block is fixed on the gyro rotor. When the gyro rotor precesses and swings laterally, the collision block is driven to precess and swing laterally, so that the collision block hits the first buffer or the second buffer.

[0007] According to one aspect of the present invention, the first buffer and the second buffer are respectively arranged on both sides of the collision block, and the height of the first buffer is higher than the height of the second buffer.

[0008] According to one aspect of the present invention, the first buffer and the second buffer are both arranged obliquely, and the two are arranged in a V shape. The first buffer is installed obliquely on the first mounting seat, and the second buffer is installed obliquely on the second mounting seat.

[0009] According to one aspect of the present invention, the impact block includes a fixed block and an impact rod, which are fixed. The fixed block is fixed to the gyro rotor by a hexagon socket screw, and the impact rod is arranged between the first buffer and the second buffer.

[0010] According to one aspect of the present invention, the first buffer and the second buffer have the same structure; the first buffer includes a sleeve, a buffer rod group, and a spring, the buffer rod group is sleeved in the sleeve, one end of the spring is connected to the sleeve, and the other end is connected to the buffer rod group.

[0011] According to one aspect of the present invention, the buffer rod set includes a sleeve rod and a buffer head, which are fixed. One end of the sleeve rod is sleeved in a sleeve and the other end is sleeved in a spring, and the spring is fixed to the buffer head.

[0012] According to one aspect of the present invention, the first mounting seat includes a mounting column and a mounting block, which are fixed. The mounting column is vertically fixed on the base, and the first buffer is installed on the mounting block.

[0013] According to one aspect of the present invention, the second mounting seat includes a mounting plate and a mounting head, which are fixed. The mounting plate is horizontally fixed on the base, and the second buffer is installed on the mounting head.

[0014] According to one aspect of the present invention, the mounting column is a columnar rigid structure, and the mounting plate is a plate-like rigid structure.

[0015] According to one aspect of the present invention, the mounting column and the mounting plate are both telescopic structures, the mounting column can drive the mounting block to telescope and lift, and the mounting plate can drive the mounting head to telescope and translate.

[0016] Advantages of the implementation of the present invention: When a ship on the sea surface rolls, the gyro rotor suppresses the ship's roll by swaying in transverse precession, and the gyro rotor swaying in transverse precession drives the impact block to sway in transverse precession, so that the impact block hits the first buffer or the second buffer, thereby being able to control the precession speed and precession angle of the gyro rotor, greatly improving the precession control of the gyro rotor by the gyro anti-roll device, so that a low-pressure hydraulic system can be used to control the precession speed and precession angle of the gyro anti-roll device, which not only reduces the equipment cost but also increases the overall life of the hydraulic system. At the same time, the present invention has a simple overall structure, is easy to disassemble and manufacture, and has low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Embodiment 1

[0023] like Figure 1 As shown, the buffer structure of the precession system of the gyro anti-roll device is provided in the gyro anti-roll device; the buffer structure of the precession system of the gyro anti-roll device comprises a base 1, a first mounting seat 7, a second mounting seat 8, a first buffer 2, a second buffer 3, and a collision block 4. The base 1 is used to install the gyro rotor 6 that sways in transverse precession, and the base 1 is installed on the ship. The first mounting seat 7 is vertically fixed on the base 1; the first mounting seat 7 comprises a mounting column 71 and a mounting block 72 that are fixedly connected to each other, wherein the mounting column 71 is columnar and vertically fixed to the base 1, and the mounting block 72 is a block structure, and its end is fixed to the mounting column 71 at a certain angle. The second mounting seat 8 is horizontally fixed on the base 1; the second mounting seat 8 comprises a mounting plate 81 and a mounting head 82 that are fixedly connected to each other, both of which are plate-shaped, wherein the mounting plate 81 is horizontally fixed to the base 1, and the mounting head 82 is tilted and fixed to the mounting plate 81 at a certain angle. The first buffer 2 is installed obliquely on the mounting block 72 of the first mounting seat 7; the first buffer 2 and the second buffer 3 are relatively obliquely arranged on the left and right sides of the impact block 4, and the first buffer 2 and the second buffer 3 are arranged in a V shape as a whole; the height of the first buffer 2 is higher than that of the second buffer 3. The second buffer 3 is installed obliquely on the mounting head 82 of the second mounting seat 8. The impact block 4 is fixed on the gyro rotor 6 by the hexagon socket screw 5. When the ship on the sea surface rolls, the gyro rotor 6 suppresses the ship's roll by lateral precession swing; the gyro rotor 6 that lateral precession swings drives the impact block 4 to lateral precession swing (i.e., left and right swing in the figure), so that the impact block 4 hits the first buffer 2 or the second buffer 3, so that the precession speed and precession angle of the gyro rotor 6 can be controlled, which greatly improves the precession control of the gyro rotor 6 by the gyro anti-roll device. In this way, a low-pressure hydraulic system can be used to control the precession speed and precession angle of the gyro anti-roll device, which not only reduces the equipment cost but also improves the overall life of the hydraulic system.

[0024] In this embodiment, the impact block 4 includes an integrally arranged fixed block 41 and an impact rod 42, wherein the fixed block 41 is fixed to the gyro rotor 6 by means of a hexagon socket screw 5, and the impact rod 42 is arranged between the first buffer 2 and the second buffer 3; the fixed block 41 is in a round block shape, and the impact rod 42 is in a bar or plate shape, and the combined shape of the two is in a "whistle" shape as a whole. The impact block 4 precesses along the precession direction along with the gyro rotor 6, and at the ends of the precession on both sides, it is buffered by two buffers mounted on two mounting seats, so as to better control the precession speed and precession angle of the gyro rotor 6.

[0025] In this embodiment, the structures of the first buffer 2 and the second buffer 3 are consistent. The first buffer 2 includes a sleeve 21, a buffer rod group, and a spring 22; wherein the sleeve 21 is cylindrical, the sleeve 21 of the first buffer 2 is fixed on the mounting block 72, and the sleeve 21 of the second buffer 3 is fixed on the mounting head 82; the buffer rod group includes a sleeve rod 23 and a buffer head 24 fixed to each other, one end of the sleeve rod 23 is sleeved in the sleeve 21, and the other end is sleeved in the spring 22; one end of the spring 22 is fixedly connected to the sleeve 21, and the other end is fixedly connected to the buffer head 24, and the spring 22 is used for the telescopic reset of the buffer rod group, and for mitigating the impact of the collision block 4. The buffer head 24 is a block structure, which can be made of rubber material or a layer of rubber is fixed on its surface, and is used to buffer the impact of the collision block 4; the sleeve rod 23 is telescopic in the sleeve 21 and cooperates with the spring 22 to mitigate the impact of the collision block 4.

[0026] In this embodiment, the mounting column 71 is a columnar rigid structure, that is, the mounting column 71 is a whole column, which can be integrally provided with the mounting block 72; the mounting plate 81 is a plate-like rigid structure, that is, the mounting plate 81 is a whole square plate, which can be integrally provided with the mounting head 82 and is an integral bent plate structure. In this way, the structure is more stable.

[0027] The beneficial effects of this embodiment are as follows: compared with the existing gyro anti-roll device in which the precession speed and the precession angle of the gyro rotor 6 are completely controlled by the hydraulic system, the present invention greatly improves the control of the precession torque of the precession end of the gyro rotor 6 by the gyro anti-roll device by adding a collision block 4 to the gyro rotor 6 and using a buffer at the precession end of the gyro rotor 6, which not only reduces the working pressure of the hydraulic system, but also increases the life of the hydraulic system and reduces the equipment cost. At the same time, the present invention has a simple overall structure, is easy to disassemble and manufacture, and has a low cost.

[0028] Embodiment 2

[0029] The difference between this embodiment and the first embodiment is that the mounting column 71 and the mounting plate 81 in this embodiment adopt an integrated rigid structure, but the mounting column 71 and the mounting plate 81 are designed as telescopic structures, the mounting column 71 can drive the mounting block 72 to telescope and lift, and the mounting plate 81 can drive the mounting head 82 to telescope and translate.

[0030] In this embodiment, the mounting column 71 and the mounting plate 81 can both adopt a telescopic structure such as a cylinder or an electric push rod, and the protruding end of the mounting column 71 is fixedly connected to the mounting block 72, and the protruding end of the mounting plate 81 is fixedly connected to the mounting head 82. In this way, the relative position or angle of the two buffers and the collision block 4 can be adjusted, which is more convenient to use and more applicable.

[0031] The beneficial effect of this embodiment is that by designing the mounting column 71 and the mounting plate 81 as telescopic structures, the present invention can adjust the relative position or angle of the two buffers and the collision block 4, which is more convenient to use and more applicable.

[0032] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
