Description

Technical Field

[0001] The present invention belongs to the technical field of ship engineering, and specifically relates to a side-release device for marine lifeboats. Background Art

[0002] A side-release device for marine lifeboats refers to a device installed on the side of a ship for releasing a lifeboat from its storage position and launching it into the water; its main function is to enable the lifeboat to quickly break away from the ship in case of an emergency, providing an escape opportunity for the people in distress;

[0003] Currently, the traditional side-release device for marine lifeboats rotates by driving a winch, causing the steel cable to fall off the surface of the winch; as the steel cable is released, the supporting structure connected to it will rotate accordingly, and this chain reaction enables the lifeboat to move smoothly from the storage position to the side of the ship; subsequently, the steel cable continues to play its role, slowly and steadily lifting the lifeboat onto the sea surface, and then the handle of the hook can be pulled to disengage the hook from the surface of the lifeboat, thus completing the release of the lifeboat;

[0004] However, being exposed to the marine environment with high humidity, high salinity and full of corrosive substances for a long time; such harsh environmental conditions will cause rust to quickly accumulate on the surface of the hook; the accumulation of rust may lead to the phenomenon of the hook getting stuck; when the hook is tightly wrapped by rust, the frictional resistance between its various components will increase significantly, making the originally flexible and smooth rotation extremely difficult, thereby reducing the overall safety of the lifeboat release device.

Detailed implementation mode

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0035] As Figures 1 to 10 shown, the present invention provides a side-releasing device for a marine lifeboat, including a main body 1. A winch 2 is arranged on the surface of the main body 1. A support rod 22 is rotatably connected inside the main body 1. A steel cable 3 located at one end of the support rod 22 is wound around the surface of the winch 2;

[0036] A fixing assembly, which is arranged at one end of the steel cable 3. The fixing assembly includes a housing 4;

[0037] A lubrication mechanism, which is arranged at the top of the housing 4. The lubrication mechanism includes a fuel tank 8. The fuel tank 8 is fixedly connected to the top of the housing 4. A liquid outlet pipe 9 located inside the housing 4 is fixedly installed on one side of the outer surface of the fuel tank 8. A fixed housing 10 is fixedly installed in the inner cavity of the fuel tank 8. A first spring 11 is fixedly installed inside the fixed housing 10. One end of the first spring 11 is fixedly installed with a sealing rod 12 located inside the fixed housing 10. One end of the sealing rod 12 is fixedly installed with a plugging block 13 located at one end of the liquid outlet pipe 9. A first connecting block 14 is fixedly installed at the top of the sealing rod 12. A square housing 15 is fixedly installed at the top of the fuel tank 8. A lead screw 17 is slidably connected inside the square housing 15. An extrusion block 19 located at the top of the first connecting block 14 is arranged at the bottom end of the lead screw 17. A first gear 18 located on the surface of the lead screw 17 is rotatably connected to the bottom end of the square housing 15, and the lead screw 17 is threadedly connected to the first gear 18;

[0038] A driving assembly, which is arranged on one side of the square housing 15.

[0039] Adopt the above - mentioned scheme: The operator sleevs the fixing component on both ends of the lifeboat. When it is necessary to release the lifeboat, the winch 2 can be driven to rotate, so that the steel cable 3 disengages from the surface of the winch 2. Then the support rod 22 will rotate, and then drive the lifeboat to move to one side of the ship. Then the steel cable 3 will lift and place the lifeboat on the sea surface. Then the fixing component can be removed from the hanging ring of the lifeboat, thus completing the release work;

[0040] When working for a long time and it is necessary to lubricate the fixing component, the driving component can be driven. Then the driving component will drive the first gear 18 to rotate. Since the first gear 18 is threadedly connected to the lead screw 17, when the first gear 18 rotates, the lead screw 17 will move. The lead screw 17 will push the extrusion block 19 to move. Then the bottom end of the extrusion block 19 will contact the top end of the first connecting block 14 and push the first connecting block 14 to move. The first connecting block 14 will drive the sealing rod 12 to contract into the interior of the fixed housing 10 and compress the first spring 11. Then the sealing rod 12 will drive the blocking block 13 to move, and the blocking block 13 will cancel the blockage of the liquid outlet pipe 9. Then the lubricating oil in the oil storage tank 8 will enter the interior of the liquid outlet pipe 9, and the liquid outlet pipe 9 can lubricate the fixing component. Finally, by driving the driving component, the blocking block 13 cancels the blockage of the liquid outlet pipe 9, thereby lubricating the fixing component, reducing the frictional resistance of the fixing component, making the fixing component more flexible and smooth during operation, and improving the overall safety of the lifeboat release device.

[0041] As Figures 1 to 4 and Figure 7 shown, the housing 4 is fixedly connected to one end of the steel cable 3. Inside the housing 4, a first connecting rod 5 is fixedly installed. The surface of the first connecting rod 5 is rotatably connected to a hook 6, and inside the housing 4, a handle 7 is rotatably connected.

[0042] Adopt the above - mentioned scheme: Through the design of the first connecting rod 5, the hook 6 and the handle 7, the handle 7 can be pulled to rotate. Then one end of the handle 7 will contact the surface of the hook 6 and push the hook 6 to rotate on the surface of the first connecting rod 5, thereby releasing and fixing the lifeboat. And when the lubricating oil flows out from the interior of the liquid outlet pipe 9, it will flow respectively at the connection between the first connecting rod 5 and the hook 6 and the connection between the handle 7 and the housing 4, thereby reducing the frictional resistance between each component.

[0043] As Figure 5 and Figure 10 shown, the driving component includes a motor 20. The motor 20 is fixedly connected to one side of the square housing 15, and the output end of the motor 20 is fixedly installed with a second gear 21 that meshes with the motor 20.

[0044] Adopting the above solution: Through the design of the motor 20 and the second gear 21, the motor 20 can be driven to rotate the second gear 21. Since the second gear 21 meshes with the first gear 18, the rotating second gear 21 will drive the first gear 18 to rotate, thereby driving the lubrication mechanism to lubricate the fixed component.

[0045] As Figures 4 to 7 shown, it further includes a swinging mechanism, which is arranged at the top of the oil storage tank 8. The swinging mechanism includes a third gear 23, and the third gear 23 is rotatably connected to the top of the oil storage tank 8. A rack 24 is fixedly installed at the top of the extrusion block 19. A sliding ring 26 is arranged on one side of the third gear 23, and a second connecting block 25 located inside the sliding ring 26 is fixedly installed on one side of the third gear 23. A second connecting rod 27 is fixedly installed on one side of the sliding ring 26, and a toothed plate 28 is fixedly installed at one end of the second connecting rod 27. A fourth gear 29 is arranged on one side of the housing 4, and one side of the fourth gear 29 is fixedly connected to the handle 7.

[0046] Adopting the above solution: Through the design of the swinging mechanism, when the extrusion block 19 extrudes and moves the first connecting block 14, the extrusion block 19 can be continuously driven to descend. Then the extrusion block 19 will drive the rack 24 to move. When the rack 24 moves, the teeth on its surface will mesh with the teeth on the surface of the third gear 23. Then the moving third gear 23 will drive the second connecting block 25 to move inside the sliding ring 26, and the second connecting block 25 will drive the sliding ring 26 to move. The sliding ring 26 will drive the second connecting rod 27 to move, and the second connecting rod 27 will drive the toothed plate 28 to move. Since the toothed plate 28 meshes with the fourth gear 29, the toothed plate 28 will drive the fourth gear 29 to rotate, and the fourth gear 29 will drive the handle 7 to rotate. When the handle 7 rotates, it will push the lifting hook 6 to swing on the surface of the first connecting rod 5. Finally, the handle 7 is swung by driving the rack 24 through the extrusion block 19, and then the handle 7 pushes the lifting hook 6 to swing, so that the lubricating oil can be evenly distributed at the joints of the first connecting rod 5 and the lifting hook 6 and between the handle 7 and the housing 4, ensuring the effectiveness of lubrication.

[0047] As Figure 1 、 Figure 8 and Figure 9 shown, it further includes a shock-absorbing mechanism, which is arranged inside the main body 1. The shock-absorbing mechanism includes a fixed rod 30, and the fixed rod 30 is fixedly connected to the inside of the main body 1. Two sliders 31 are slidably sleeved on the surface of the fixed rod 30. Elastic springs 32 located on the surface of the fixed rod 30 are elastically connected between the opposite sides of the two sliders 31 and the main body 1. A shock-absorbing block 33 is arranged at the top of the slider 31, and a hinge block 34 is fixedly installed at the bottom of the shock-absorbing block 33. The hinge block 34 is hinged to the two sliders 31 through hinge rods 35.

[0048] Adopting the above solution: Through the design of the shock-absorbing mechanism, when the support rod 22 rotates, its surface will contact the top of the shock-absorbing block 33, and then push the shock-absorbing block 33 downward. The shock-absorbing block 33 will drive the hinge block 34 downward. Since the hinge block 34 and the slider 31 are hinged by the hinge rod 35, when the hinge block 34 descends, it will push the hinge rod 35 to rotate, and the hinge rod 35 will push the slider 31 to move towards each other on the surface of the fixed rod 30. Then, the moving slider 31 will compress the second spring 32. Through the compression of the second spring 32, the shock-absorbing block 33 can shock-absorb the support rod 22, preventing the impact generated when the support arm contacts the inside of the main body 1 from damaging its connecting components, thereby extending its service life.

[0049] As Figure 4 and Figure 5 shown, a fixing hole 36 is formed on the surface of the square shell 15. A first limiting block 37 located inside the fixing hole 36 is fixedly installed at the top of the first gear 18, and the surface of the first limiting block 37 fits with the inner wall of the fixing hole 36.

[0050] Adopting the above solution: Through the design of the fixing hole 36 and the first limiting block 37, when the first gear 18 moves, it will drive the first limiting block 37 to move inside the fixing hole 36. Since the surface of the first limiting block 37 fits with the inner wall of the fixing hole 36, the first gear 18 can be limited when the first limiting block 37 moves.

[0051] As Figure 5 and Figure 6 shown, a sliding groove 39 is formed inside the fuel storage tank 8. A second limiting block 40 is slidably connected inside the sliding groove 39. One side of the second limiting block 40 is fixedly connected to the extrusion block 19. A stop block 38 located on the surface of the rack 24 is fixedly installed at the top of the fuel storage tank 8. The rack 24 can move inside the stop block 38, and the stop block 38 is trapezoidally designed.

[0052] Adopting the above solution: Through the design of the sliding groove 39 and the second limiting block 40, when the extrusion block 19 moves, it can drive the second limiting block 40 to move inside the sliding groove 39. Then, the moving second limiting block 40 can limit the moving direction of the extrusion block 19 and ensure that the extrusion block 19 can move stably. Through the design of the stop block 38, when the rack 24 moves, it can move inside the stop block 38, and the stop block 38 is trapezoidally designed, so as to block the lubricating oil and prevent the lubricating oil from flowing out from the connection between the fuel storage tank 8 and the rack 24.

[0053] As Figure 5 and Figure 6As shown in the figure, a second protective shell 41 is fixedly installed at the top of the fuel storage tank 8, and the second connecting rod 27 can move inside the second protective shell 41. A first protective shell 16 located on the surface of the toothed plate 28 is fixedly installed on the surface of the housing 4. Square holes are opened at both ends of the first protective shell 16, and the toothed plate 28 can move inside the square holes. The blocking block 13 is designed in a semicircle. An arc-shaped groove is opened inside the fuel storage tank 8, and the blocking block 13 can move inside the arc-shaped groove.

[0054] Adopting the above scheme: Through the design of the second protective shell 41 and the first protective shell 16, since the second protective shell 41 is provided at the top of the fuel storage tank 8, the second protective shell 41 can protect the lubrication mechanism and the swing mechanism. Then, the second protective shell 41 can also support the second connecting rod 27, and the second connecting rod 27 can support the sliding ring 26. And the first protective shell 16 can protect the toothed plate 28 and the fourth gear 29. Since square holes are opened on both sides of the first protective shell 16, the first protective shell 16 will not interfere with the movement of the toothed plate 28. Through the design of the blocking block 13 and the fuel storage tank 8, since the blocking block 13 is designed in a semicircle, its blocking effect can be increased. And an arc-shaped groove is opened inside the fuel storage tank 8, so the fuel storage tank 8 will not interfere with the movement of the blocking block 13.

[0055] The working principle and usage process of the present invention:

[0056] By the operator sleeving the fixing component on both ends of the lifeboat. When it is necessary to release the lifeboat, the winch 2 can be driven to rotate, so that the steel cable 3 is separated from the surface of the winch 2. Then the support rod 22 will rotate. When the support rod 22 rotates, its surface will contact the top of the shock-absorbing block 33, and then the shock-absorbing block 33 will be pushed down. The shock-absorbing block 33 will drive the hinge block 34 to descend. The hinge block 34 will push the hinge rod 35 to rotate. The hinge rod 35 will push the slider 31 to move towards each other on the surface of the fixed rod 30. Then the moving slider 31 will squeeze the second spring 32. Through the compression of the second spring 32, the shock-absorbing block 33 can shock-absorb the support rod 22. Then it will drive the lifeboat to move towards one side of the ship. Then the steel cable 3 will lift and place the lifeboat on the sea surface. Then the fixing component can be removed from the hanging ring of the lifeboat, thus completing the release work;

[0057] When lubricating the fixed components during long-term operation, the motor 20 can be driven to rotate the second gear 21. The second gear 21 will drive the first gear 18 to rotate. The lead screw 17 will move inside the first gear 18. The lead screw 17 will push the extrusion block 19 to move. Then the extrusion block 19 will contact the first connecting block 14 and push the first connecting block 14 to move. The first connecting block 14 will drive the sealing rod 12 and the blocking block 13 to move. The blocking block 13 will cancel the blockage of the liquid outlet pipe 9. Then the lubricating oil inside the oil storage tank 8 will enter the inside of the liquid outlet pipe 9. The liquid outlet pipe 9 can lubricate the joints between the first connecting rod 5 and the hook 6 and between the handle 7 and the housing 4.

[0058] When the extrusion block 19 squeezes the first connecting block 14 to move, the extrusion block 19 can be continuously driven to descend. Then the extrusion block 19 will drive the rack 24 to move. The teeth on its surface will mesh with the teeth on the surface of the third gear 23. Then the third gear 23 will drive the second connecting block 25 to move inside the sliding ring 26. And the second connecting block 25 will drive the sliding ring 26 to move. The sliding ring 26 will drive the second connecting rod 27 and the toothed plate 28 to move. Further, the toothed plate 28 will drive the fourth gear 29 to rotate. And the fourth gear 29 will drive the handle 7 to rotate. When the handle 7 rotates, it will push the hook 6 to swing on the surface of the first connecting rod 5. Thus, the lubricating oil is evenly distributed at the joints between the first connecting rod 5 and the hook 6 and between the handle 7 and the housing 4, and the operation process is finally completed.
