Description

Technical Field

[0001] This utility model relates to the field of maritime rescue technology, and in particular to a sliding rail type maritime rescue basket. Background Technology

[0002] Traditional throw-type lifebuoys or life poles rely on manual aiming and deployment, which is greatly affected by wind and waves, resulting in a hit rate of less than 40%. Currently, robotic arms or gondola-type equipment are used to deploy lifebuoys or life poles, but robotic arms have a small operating radius, typically no more than 3 meters in length, making it difficult to cover the side areas of large ships; while gondola-type equipment requires coordination with a powered vessel to deploy lifebuoys or life poles, making them inconvenient to use and unable to be directly deployed on board. Summary of the Invention

[0003] In view of this, the present invention provides a sliding rail type marine rescue basket to solve the problems existing in the background art.

[0004] A sliding rail type marine rescue basket includes a telescopic beam outer frame, a telescopic beam slidably disposed within the telescopic beam outer frame via a pulley assembly, a power mechanism for allowing the telescopic beam to slide along the length direction of the telescopic beam outer frame, a lifting mechanism fixed to the bottom of the telescopic beam, and a rescue basket connected to the lifting mechanism by a wire rope.

[0005] The telescopic beam outer frame is arranged along the width of the ship and is fixed to a strong structure located at the bottom of the deck. The lifting mechanism is used to lift the life basket up and down.

[0006] Preferably, the telescopic beam outer frame is composed of two symmetrically arranged rectangular frames, a part of the pulley assembly is fixed in the groove of one of the rectangular frames, and the other part of the pulley assembly is fixed in the groove of the other opposite rectangular frame.

[0007] Preferably, the pulley assembly includes a first pulley arranged vertically and a second pulley arranged horizontally. Multiple sets of first pulleys and multiple sets of second pulleys are provided on both sides of the telescopic beam, and the first pulley and second pulley on one side are alternately arranged along the length of the telescopic beam. Each set of first pulleys and each set of second pulleys are fixed to the inner wall of the outer frame of the telescopic beam through their respective axles.

[0008] Preferably, the power mechanism includes a rack fixed to the bottom of the telescopic beam and a motor fixed to the outer frame of the telescopic beam, wherein the rack meshes with a gear at the end of the motor output shaft.

[0009] Preferably, the lifting mechanism includes a winch, which is disposed on the side of the bottom of the telescopic beam.

[0010] Preferably, the upper part of the rescue basket is also fixed with an anti-sway rope.

[0011] Preferably, the lifting mechanism includes a wire pulley and a winch. The wire pulley is located on the side of the bottom of the telescopic beam, and the winch is located at another position on the bottom of the telescopic beam. The wire rope of the winch passes around the wire pulley and is connected to the rescue basket.

[0012] Preferably, a life-saving grab handle is installed at the lower part of the life-saving basket.

[0013] Preferably, the deck is a single-layer deck, which refers to the deck above the main deck of the ship.

[0014] The beneficial effects of this utility model are:

[0015] 1. The marine rescue basket of this application is fixed to a strong structure at the bottom of the first deck. The telescopic beam driven by the motor can accurately move the rescue basket to the position above the person in the water within the outer frame of the telescopic beam. Then, the rescue basket is lowered by the winch, which can accurately rescue the person in the water and improve the reliability and success rate of rescue in complex sea conditions.

[0016] 2. This application directly fixes the outer frame of the telescopic beam to the strong structure at the bottom of the first deck, without modifying the hull structure, and will not cause damage to the hull structure during the installation process.

[0017] 3. The telescopic beam frame of this application spans the entire width of the ship, which can extend the operating radius to 4 meters, covering the rescue of dangerous areas within 0-6 meters outside the ship's side, effectively increasing the rescue range. At the same time, it shortens the entire rescue response time to within 30 seconds, effectively shortening the rescue time, improving rescue efficiency, increasing the survival rate of people who fall into the water, and enabling the rapid retrieval of the life basket.

[0018] 4. The maritime rescue basket of this application is fixed to the wall structure at the bottom of the first deck, which can be applied to the deck structure of different ship types. It has a wide range of applications and has high promotion and application value.

[0019] 5. The upper part of the rescue basket of this application is fixed with an anti-sway rope. The anti-sway rope limits the swing amplitude of the rescue basket during the lowering process and limits the swing amplitude of the rescue basket during the retraction and ascent process, so as to achieve accurate deployment and retrieval of the rescue basket, and at the same time reduce the discomfort caused by the swaying of the rescue basket to the rescuers and / or people in the water.

Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0043] To better understand the technical solution of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings.

[0044] This utility model provides a sliding rail type marine rescue basket, including a telescopic beam outer frame 1, a telescopic beam 4 slidably disposed in the telescopic beam outer frame 1 via a pulley assembly, a power mechanism for sliding the telescopic beam 4 along the length direction of the telescopic beam outer frame 1, a lifting mechanism fixed to the bottom of the telescopic beam 4, and a rescue basket 8 connected to the wire rope 7 of the lifting mechanism.

[0045] Specifically, the telescopic beam outer frame 1 is arranged along the width of the ship and consists of two symmetrically arranged rectangular frames. Both rectangular frames are fixed to a strong structure located at the bottom of the deck, and the rectangular slots of the two rectangular frames are arranged opposite each other. The deck is a single-level deck, which refers to the deck above the main deck of the ship. In this embodiment, the telescopic beam outer frame 1 consists of two symmetrically arranged channel steels.

[0046] A portion of the pulley assembly is fixed in a groove in one of the rectangular frames of the telescopic beam outer frame 1, and another portion of the pulley assembly is fixed in a groove in another opposite rectangular frame.

[0047] The pulley assembly includes a first pulley 2 arranged vertically and a second pulley 3 arranged horizontally. Multiple sets of first pulleys 2 and multiple sets of second pulleys 3 are provided on both sides of the telescopic beam 4, and the first pulleys 2 and second pulleys 3 on one side are arranged alternately along the length of the telescopic beam 4. Each set of first pulleys 2 and each set of second pulleys 3 are fixed to the inner wall of the outer frame 1 of the telescopic beam through their respective axles.

[0048] Rectangular grooves are also provided on both sides of the telescopic beam 4, and these rectangular grooves are opposite to the rectangular grooves of the outer frame 1 of the telescopic beam. By vertically positioning the first pulley 2, the wheel surface of the first pulley 2 can contact the upper and lower inner groove surfaces of the rectangular groove of the telescopic beam 4 to support the telescopic beam 4, avoiding contact between the top and bottom surfaces of the telescopic beam 4 and the outer frame 1, which would cause friction and affect the smooth sliding of the telescopic beam 4. By horizontally positioning the second pulley 3, the wheel surface of the second pulley 3 can contact the side groove surface of the rectangular groove of the telescopic beam 4. Under the power provided by the power mechanism, the second pulley 3 cooperates with the first pulley 2. Driven by the power mechanism, the friction between the wheel surfaces of the first pulley 2 and the second pulley 3 and the telescopic beam 4 allows the telescopic beam 4 to slide within the outer frame 1 of the telescopic beam. During the sliding process of the telescopic beam 4, the second pulley 3 also plays a guiding role.

[0049] The power mechanism includes a rack 6 fixed to the bottom of the telescopic beam 4 and a motor 10 fixed to the outer frame 1 of the telescopic beam. The rack 6 meshes with the gear at the end of the output shaft of the motor 10.

[0050] When installing the power mechanism, an L-shaped support plate is fixed to the outer side of the telescopic beam outer frame 1. The motor 10 is fixed to the horizontal section of the support plate. The rack 6 is fixed to the bottom of the telescopic beam 4 with its teeth facing downwards, or the teeth of the rack 6 can face outwards from the telescopic beam outer frame 1. Then, the rack 6 meshes with the gear fixed to the output shaft of the motor. In this way, after starting the motor 10, the telescopic beam 4 can move within the telescopic beam outer frame 1 under the action of the gear and the rack 6. When the telescopic beam 4 moves, the lifting mechanism fixed to its bottom can move synchronously with it.

[0051] The lifting mechanism is used to lift the life basket 8 up and down.

[0052] In one embodiment, the lifting mechanism includes a winch 9, which is located on the side of the bottom of the telescopic beam 4. The wire rope 7 of the winch 9 is connected to the life basket 8. The winch 9 smoothly releases its wire rope 7 to lower the life basket 8 to the target position, and after the winch 9 winds up the wire rope 7, it can move the life basket 8 upward.

[0053] In another embodiment, the lifting mechanism includes a wire rope pulley 5 and a winch 9. The wire rope pulley 5 is located on the side of the bottom of the telescopic beam 4, and the winch 9 is located at another position on the bottom of the telescopic beam 4. The wire rope 7 of the winch 9 passes around the wire rope pulley 5 and is connected to the rescue basket 8. The winch 9 smoothly releases its wire rope 7 to lower the rescue basket 8 to the target position, and after the winch 9 winds up the wire rope 7, it can move the rescue basket 8 upwards.

[0054] The rescue basket 8 is used to carry rescuers and people who have fallen into the water. A rescue grab bar 81 is installed at the bottom of the rescue basket 8 so that conscious people who have fallen into the water can actively grab it. If the person who has fallen into the water is unconscious, rescuers can retrieve the unconscious person from inside the rescue basket 8.

[0055] In another embodiment, an anti-sway rope 82 is fixed to the upper part of the rescue basket. The anti-sway rope 82 limits the swing amplitude of the rescue basket 8 during the lowering process and limits the swing amplitude of the rescue basket 8 during the retraction and ascent process, so as to achieve accurate deployment and retrieval of the rescue basket 8, and at the same time reduce the discomfort caused by the swaying of the rescue basket to the rescuers and / or people in the water.

[0056] When using the sliding rail type marine rescue basket of this application, the motor 10 first moves the telescopic beam 4 towards the side of the ship to move the rescue basket 8 to a position above the person in the water outside the ship. During the movement of the rescue basket 8 overboard, the crew members need to hold onto the other end of the anti-sway rope 82. Then, the winch 9 lowers the rescue basket 8 into the water. During the descent, the crew members need to pull the anti-sway rope 82 taut to reduce the swaying amplitude of the rescue basket 8. After the rescue basket 8 reaches the water surface, the rescuer can begin to rescue the person in the water. If the person in the water is conscious, they can actively grab the rescue grab handle 81 at the bottom of the rescue basket 8. Rescuers help the person in the water into the life basket 8. If the person in the water is unconscious, the rescuers in the life basket 8 use salvage tools to directly rescue and retrieve the unconscious person. Then, the winch 9 winds up the steel cable 7, moving the life basket 8 upwards. During the upward movement of the life basket 8, the people on the ship still need to pull the anti-sway rope 82 taut to reduce the swaying amplitude of the life basket 8. When the life basket 8 moves to a position slightly above the deck, the motor 10 is used to move the telescopic beam 4 in the opposite direction, moving the life basket 8 towards the center of the ship. After the life basket is moved to a suitable position and placed on the deck, the life basket 8 is disconnected from the steel cable 7.

[0057] It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
