Description
Technical Field
[0001] This invention relates to the field of marine elevator technology, specifically to an anti-sway marine elevator. Background Technology
[0002] Marine elevators are elevators specifically designed and installed for ships. They possess unique functions and requirements, such as earthquake resistance, corrosion resistance, space saving, and automatic docking. Marine elevators can be categorized into five main types: passenger elevators, crew elevators, cargo elevators, ship owner escalators, and food lifts. Different types of marine elevators can be selected based on the type and purpose of the ship. The manufacture and maintenance of marine elevators require specialized technicians and equipment, typically provided by professional marine elevator companies. Ships experience six forms of rolling, pitching, yaw, heave, and swaying in rough seas, with rolling, pitching, and heave having the most significant impact on the normal operation of ship equipment. When a ship rolls, the guide rails and car of the marine elevator are subjected to strong horizontal forces, increasing the stress on the horizontal structural components and preventing structural deformation or damage that could cause the elevator to stop operating. The key to solving this problem is to balance the elevator components within the ship's elevator shaft. To address this, a marine elevator has been proposed, such as the Chinese patent (patent number: CN201820497975.3, patent title: A marine elevator).
[0003] However, in actual use, traditional marine elevators are difficult to adapt to the swaying of the ship, making it difficult for users to maintain a relatively upright standing position and providing a more comfortable riding experience, thus causing inconvenience. Summary of the Invention

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0030] Example 1: The present invention provides a technical solution: an anti-sway ship elevator, including a car body 1. A steel cable 2 is provided above the car body 1, which is driven and pulled by a power mechanism to move the car body 1 up and down in the shaft. A top plate 3 is fixedly connected to the bottom of the steel cable 2. A groove 4 is formed on the outer contour of the top plate 3. A roller 5 is rotatably connected to the inner wall of the groove 4. The outer contour of the roller 5 is rotatably connected to the inner wall of the shaft where the car body 1 is located. An auxiliary rotating component 6 is fixedly connected to the bottom of the top plate 3. The bottom of the auxiliary rotating component 6 is fixedly connected to the top of the car body 1.
[0031] Working principle of Example 1:
[0032] refer to Figure 1 The user sits inside the car body 1, which rises and falls accordingly. The power motor rotates to wind and release the steel cable 2, thereby driving the car body 1 to rise and fall.
[0033] With the setting of the top plate 3, which is located in the hoistway of the car body 1, its horizontal movement range is limited, that is, the horizontal movement play is reduced. The purpose of leaving a certain amount of play is to allow air circulation. The car body 1 is generally equipped with a fan, and the flowing air can reduce the risk of exposure to air pollution.
[0034] The groove 4 provides space for the roller 5 to rotate. The outer contour of the roller 5 rolls on the inner wall of the shaft, further defining the range of vertical movement within the shaft. This ensures air circulation while further guaranteeing the stability of the movement and preventing the elevator from being affected by the swaying of the ship on the water.
[0035] Through the transmission of the auxiliary rotating component 6, while ensuring that the car body 1 rises and falls synchronously with the top plate 3, the car body 1 is further prevented from tilting synchronously with the hull and still maintaining a tendency to run vertically.
[0036] Example 2, based on Example 1, further includes:
[0037] The auxiliary rotating assembly 6 includes an n-shaped frame 7 fixedly connected to the lower surface of the top plate 3. A rectangular frame 8 is fixedly connected to the bottom of the n-shaped frame 7. A shaft 9 is rotatably connected to the inner wall of the rectangular frame 8 through a fixed axis. A shaft 10 is fixedly connected to the surface of the shaft 10 through a horizontal and vertical penetration. A collar 11 is rotatably connected to the arc-shaped contour near both ends of the shaft 10. A U-shaped frame 12 is fixedly connected to the bottom of the collar 11. A column 13 is fixedly connected to the lower surface of the U-shaped frame 12. Two extension frames 14, which are rotatably coupled to the shaft 19 and symmetrically arranged, are fixedly connected to the outer contour of the rectangular frame 8. Two extension frames 14, which are rotatably coupled to the shaft 10, are also fixedly connected to the outer contour of the rectangular frame 8. The extension frame 15 is arranged symmetrically. The surfaces of the extension frame 14 and the extension frame 15 are both penetrated and fixedly connected to the universal ball seat 16. The inner wall of the universal ball seat 16 is rotatably connected to the universal ball 17. The bottom of the universal ball 17 is fixedly connected to the telescopic kit 18. The bottom of the telescopic kit 18 is fixedly connected to the universal ball 19. The universal ball seat 20 is fitted on the arc-shaped contour near the bottom of the universal ball seat 16. The bottom of the column 13 and the four universal ball seats 20 are fixedly connected to the upper surface of the connecting base plate 61. The lower surface of the connecting base plate 61 is fixedly connected to the connecting bottom column 21. The lower surface of the connecting bottom column 21 is fixedly connected to the top of the car body 1.
[0038] Working principle of Example 2: (Refer to...) Figure 1 and Figure 2 .
[0039] The transmission connection between the top plate 3 and the car body 1 in the vertical direction is achieved by setting up the n-shaped frame 7, rectangular frame 8, shaft one 9, shaft two 10, collar 11, U-shaped frame 12, column 13, connecting bottom column 21 and auxiliary rotation component 6. The specific content regarding relative rotation is as follows;
[0040] The U-shaped frame 12 is supported by the column 13, and the rotation of the second shaft 10 is supported by the collar 11 on the top of the U-shaped frame 12. Since the first shaft 9 is penetrated and fixedly connected by the second shaft 10, the first shaft 9 and the rectangular frame 8 on the first shaft 9 will rotate synchronously in the direction of arrow B.
[0041] Furthermore, since the rectangular frame 8 is penetrated by the shaft 9 and is rotatably connected to the shaft 9, the rectangular frame 8 as a whole can rotate relative to the shaft 9 in the direction of arrow A. Thus, the rectangular frame 8 and the n-shaped frame 7 as a whole can rotate relative to the column 13, the connecting base plate 61, the connecting base column 21, and the car body 1 in the directions of arrow A and arrow B. Since the car body 1 does not need to rotate in the horizontal direction, the rotation in the directions of arrow A and arrow B can ensure that after the ship tilts, the car body 1 can maintain its vertical position by rotating in the directions of arrow A and arrow B, so that the passengers in the car body 1 can maintain a relatively comfortable riding experience.
[0042] The coordinated use of extension frame 14, extension frame 2 15, universal ball seat 16, universal ball 17, telescopic kit 18, universal ball 2 19 and universal ball seat 20 provides auxiliary support for the rotation of the rectangular frame 8 relative to the connecting base plate 61, further ensuring stability during rotation.
[0043] Specifically, through the axial telescopic cooperation of the two extension frames 14 and the universal ball seats 16, 17, 19 and 20 on the two extension frames 14 and the corresponding telescopic kit 18, the rectangular frame 8 can rotate in the direction of arrow A.
[0044] Similarly, through the axial extension and retraction of the two extension frames 15 and the universal ball joints 16, 17, 19 and 20 on the two extension frames 15 and the corresponding telescopic components 18, the rectangular frame 8 can rotate in the direction of arrow B.
[0045] Furthermore, the telescopic kit 18 includes a piston rod 22 fixed to the bottom of the universal ball 17, a piston plate 23 fixedly connected to the bottom of the piston rod 22, a piston cylinder 24 axially slidably connected to the outer contour of the piston plate 23, and the bottom of the piston cylinder 24 fixedly connected to the top of the universal ball 2 19.
[0046] The piston plate 23 slides axially along the inner wall of the piston cylinder 24 with the piston rod 22, and the universal ball 17 rotates in the universal ball seat 16 and the universal ball 29 rotates in the universal ball seat 20. Through the corresponding transmission of the extension frame 14 and the extension frame 25, the rectangular frame 8 can smoothly rotate adaptively.
[0047] When the piston plate 23 slides axially within the piston cylinder 24, the presence of air within the piston cylinder 24 further buffers the sliding of the piston plate 23 within the piston cylinder 24; while ensuring that the car body 1 can remain in a vertical state, it avoids violent shaking and achieves an anti-sway effect.
[0048] In embodiment three, four airbags 25 are fixedly connected to the outer contour of the top plate 3. After the airbags 25 are inflated, they will contact the inner wall of the shaft where the car body 1 is located.
[0049] refer to Figure 1 The four airbags 25 cover the surface of the outer contour of the top plate 3 except for the rollers 5. After the airbags 25 inflate, they contact the inner wall of the shaft where the car body 1 is located, and decelerate the sliding of the car body 1 in the inner wall of the shaft. This prevents the car body 1 from slipping off at high speed during the continuous high-frequency turbulence and shaking of the ship, and protects the passengers inside the car body 1.
[0050] In Example 4, based on Example 3, a three-way pipe 26 is fixedly connected to the bottom of two adjacent airbags 25. The bottom of the three-way pipe 26 extends into the bottom space of the piston cylinder 24. A one-way valve 27 is fixedly connected to the inner wall of the three-way pipe 26 near the bottom. A one-way valve 28 is fixedly connected to the upper surface of the piston plate 23, allowing external air to enter the piston cylinder 24 in one direction.
[0051] Working principle of Example 4:
[0052] refer to Figure 3 As the ship continues to rock, the car body 1 will adaptively rotate and adjust, causing the piston plate 23 to continuously reciprocate axially within the piston cylinder 24. This causes external air to enter the bottom space of the piston cylinder 24 through the one-way valve 28, and then enter the three-way pipe 26 through the one-way valve 27. Finally, the gas is injected unidirectionally into the airbag 25 through the two branch pipes at the top of the three-way pipe 26, achieving unidirectional replenishment of air in the airbag 25. As the ship's rocking time continues to increase and the rocking frequency increases, the replenishment efficiency of air in the airbag 25 will be accelerated. Eventually, the airbag 25 will continue to expand and contact and compress with the inner wall of the shaft, achieving the effect described above.
[0053] Furthermore, the airbag 25 has micropores on its arc-shaped contour.
[0054] Considering the need to easily expel the gas from the airbag 25 after inflation and restore the normal operation of the car body 1.
[0055] Furthermore, a filter screen 29, which is an activated carbon filter screen, is fixedly connected to the upper surface of the piston plate 23.
[0056] By setting the filter screen 29, the air entering the piston cylinder 24 can be filtered, and finally the air enters the air bag 25 and is discharged through the micropores on the air bag 25, thus avoiding clogging of the micropores.
[0057] The system purifies the air inside the shaft, and the purified air enters the car body 1 to provide users with cleaner air.
[0058] Working Principle: In this anti-sway ship elevator, the user sits inside the car body 1, which rises and falls accordingly. The motor rotates, winding and releasing the steel cable 2, thus driving the car body 1 to move up and down. The top plate 3, located within the shaft where the car body 1 rises and falls, restricts its horizontal movement range, reducing horizontal play. This play allows for air circulation; the car body 1 is typically equipped with a fan, and the flowing air reduces the risk of air pollution. The grooves 4 provide space for the rollers 5 to rotate. The rollers 5 roll along the inner wall of the shaft, further defining their vertical movement range within the shaft. This ensures air circulation while maintaining stability, further preventing the elevator's stability from being affected by the swaying of the ship on the water. Through the transmission of the auxiliary rotating component 6, the car body 1 rises and falls synchronously with the top plate 3, while also preventing the car body 1 from tilting synchronously with the ship, maintaining a tendency towards vertical operation.
