Abstract
Description
Technical Field
[0001] This utility model relates to the field of marine technology, and more specifically, to a launching device for evacuation lifeboats. Background Technology
[0002] A lifeboat is a vessel used for maritime rescue, typically mounted on large ships such as cruise ships, cargo ships, or warships, to provide a safe evacuation route for passengers and crew in emergencies. Lifeboats are generally designed to be durable, stable, and easy to operate, and are equipped with the necessary equipment and supplies to sustain life. To ensure that lifeboats can be quickly and safely launched into the water even when the ship is listing or in rough seas, they need to be equipped with launching devices.
[0003] Currently, lifeboats on ships are secured to the vessel at an angle by ropes. When needed, the ropes must be untied, and the lifeboat slides out along the inclined ramp. However, the ramp lacks any limiting devices, making it prone to tilting during release and resulting in a slow launch speed that could delay rescue efforts. Therefore, there is an urgent need to design a new lifeboat launching device for evacuation.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0005] In view of the problems in the related technologies, this utility model proposes a launching device for evacuation lifeboats to overcome the above-mentioned technical problems existing in the existing related technologies.
[0006] Therefore, the specific technical solution adopted by this utility model is as follows:
[0007] An evacuation lifeboat launching device includes: an inclined plate disposed at the bottom of the lifeboat; a support plate disposed at the top side of the inclined plate; an electric winch disposed at the top of the support plate; a connecting mechanism disposed at one end of a rope on the electric winch for connecting the lifeboat and the electric winch; a limiting mechanism disposed inside the inclined plate for limiting the lifeboat; a slide rail symmetrically disposed at the top of the limiting mechanism; and a plurality of pulleys disposed inside the slide rail and slidably connected to the surface of the lifeboat.
[0008] Furthermore, to ensure a simple and secure connection between the electric winch rope and the lifeboat, preventing breakage or loosening at the connection point under external impact and providing effective protection for the lifeboat, and allowing for easy disassembly via a pull pin when necessary, thus improving the lifeboat's launching efficiency, the connection mechanism includes a first connecting component located at one end of the rope on the electric winch; the connection mechanism also includes a second connecting component located on one side of the lifeboat's side panel; the first and second connecting components have identical structures and are axially symmetrically arranged; the first connecting component includes a connecting handle located at one end of the rope on the electric winch, with a pull pin at the top center of the connecting handle, and a limiting plate on one side of the pull pin that mates with the connecting handle; a pin is located on one side of the top of the connecting handle, with a hook on the outer side of the pin that mates with the connecting handle, and a groove at the top of the hook that mates with the limiting plate; the hook is C-shaped, with the pin located in the middle of the hook and the groove at the top of one end of the hook.
[0009] Furthermore, to accommodate lifeboats of different sizes and guide and limit their movement to prevent life-saving devices from tilting during launch and delaying rescue, the inclined plate has a placement groove that cooperates with the limiting mechanism. The bottom of the placement groove has symmetrically arranged T-shaped blocks that cooperate with the limiting mechanism, and the top of the placement groove has several limiting grooves that cooperate with the slide. The limiting mechanism includes a first sliding plate and a second sliding plate symmetrically arranged inside the placement groove. A first rack is symmetrically arranged at both ends of one side of the first sliding plate, and a cylinder is arranged on the other side. A second rack is symmetrically arranged at both ends of one side of the second sliding plate. Grooves are symmetrically arranged at both ends of one side of both the first and second sliding plates. T-shaped grooves that cooperate with the T-shaped blocks are arranged at the bottom of both the first and second sliding plates. Grooves are arranged at the top of both the first and second sliding plates. The first rack and the second rack both cooperate with the grooves. A gear is arranged between the first rack and the second rack, connected to the placement groove via a rotating shaft, and meshes with the first rack and the second rack.
[0010] The beneficial effects of this utility model are as follows:
[0011] 1) With the combined action of the inclined plate, electric winch, connecting mechanism, limiting mechanism and slide, this utility model realizes a simple and stable connection between the electric winch rope and the lifeboat. At the same time, the slide can adapt to lifeboats of different specifications and guide and limit the lifeboat to prevent the life-saving device on the lifeboat from tilting when it is launched into the water, thereby improving the launching efficiency and the timeliness of rescue.
[0012] 2) Under the action of the connecting mechanism, the electric winch rope and the lifeboat are connected in a simple and stable manner. When subjected to external impact, the connection of the connecting mechanism will not break or loosen, providing effective protection for the lifeboat. When it is necessary to untie, it can be easily disassembled by pulling the pin, improving the efficiency of launching the lifeboat.
[0013] 3) With the combined action of the ramp, limiting mechanism and slide, the slide can adapt to lifeboats of different sizes and guide and limit the lifeboats to prevent the life-saving devices on the lifeboats from tilting when they are launched into the water, thus delaying the rescue opportunity.

[0023] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.
[0024] According to an embodiment of the present invention, a device for launching evacuation lifeboats is provided.
[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-5 As shown, the evacuation lifeboat launching device according to an embodiment of the present invention includes: an inclined plate 1, disposed at the bottom of the lifeboat 2; a support plate 3, disposed at one side of the top of the inclined plate 1; an electric winch 4, disposed at the top of the support plate 3; a connecting mechanism 5, disposed at one end of a rope on the electric winch 4, for connecting the lifeboat 2 and the electric winch 4; a limiting mechanism 6, disposed inside the inclined plate 1, for limiting the lifeboat 2; a slide rail 7, symmetrically disposed at the top of the limiting mechanism 6; and a plurality of pulleys 8, disposed inside the slide rail 7 and slidably connected to the surface of the lifeboat 2.
[0026] Furthermore, in specific applications, the aforementioned inclined plate 1 is set on one side of the hull. It should be noted that the hull can be a ship, cargo ship, etc.
[0027] By utilizing the aforementioned technical solution, this utility model, through the combined action of the inclined plate 1, the electric winch 4, the connecting mechanism 5, the limiting mechanism 6, and the slide rail 7, achieves a simple and stable connection between the electric winch 4 rope and the lifeboat 2. Simultaneously, the slide rail 7 can accommodate lifeboats 2 of different specifications and guides and limits the lifeboat 2, preventing the life-saving devices on the lifeboat 2 from tilting during launch, thus improving launch efficiency and timeliness of rescue. Under the action of the connecting mechanism 5, the connection between the electric winch 4 rope and the lifeboat 2 is secured. The connection mechanism 5 provides a simple and stable connection, and will not break or loosen when subjected to external impact, thus providing effective protection for the lifeboat 2. When it needs to be disassembled, it can be easily disassembled by pulling the pin 5012, improving the launching efficiency of the lifeboat 2. With the cooperation of the inclined plate 1, the limiting mechanism 6 and the slide 7, the slide 7 can adapt to different sizes of lifeboat 2 and guide and limit the lifeboat 2, preventing the life-saving devices on the lifeboat 2 from tilting during launching and delaying the rescue opportunity.
[0028] It should be explained that the electric winch 4 is a mechanical device driven by an electric motor for lifting or pulling heavy objects. The electric winch 4 consists of an electric motor, a reducer, a drum, a rope, a brake, a control system, a base, and a rope guide. The electric motor is the power source of the electric winch, typically an AC or DC motor. The reducer reduces the output speed of the motor and increases torque to better meet the lifting requirements of heavy objects. The drum is used to wind the wire rope or cable. The diameter and width of the drum affect the lifting capacity of the winch and the capacity of the rope. The rope connects the drum and the heavy object, transmitting force and lifting the object. The brake controls the movement of the winch, preventing slippage or loss of control during lifting or lowering. The control system includes an electrical control box and operating buttons for operators to control the start, stop, lifting, and lowering of the winch. The base supports and secures other components of the winch, ensuring the stability and safety of the equipment. The rope guide guides the direction of the wire rope, preventing uneven winding or derailment on the drum; this is existing technology and will not be elaborated upon here.
[0029] Lifeboat 2 is a key piece of equipment for evacuation and rescue in maritime emergencies. It consists of a hull, power system, propulsion system, seats, communication equipment, navigation equipment, signaling devices, and a drainage system. The hull is typically made of durable materials such as fiberglass, aluminum alloy, or other composite materials to ensure buoyancy and stability in rough seas. The power system includes many lifeboats equipped with internal combustion engines or electric motors to enable autonomous navigation after leaving the mother ship. The propulsion system controls the direction and movement of the lifeboat, ensuring rapid evacuation from danger zones in emergencies. Seats provide passengers with secure and safe seating to prevent injury during navigation. Communication equipment includes radios or other communication devices to maintain contact with rescuers or other vessels. Navigation equipment, such as a compass, aids in positioning and navigation. Emergency supplies include life jackets, first-aid kits, and food supplies to support passengers' survival needs before rescue. Signaling devices, such as signal lights, smoke grenades, or audible devices, help rescuers locate and identify the lifeboat's position. The drainage system ensures that water inside the lifeboat is quickly drained, keeping the interior dry and stable; this is existing technology and will not be elaborated upon here.
[0030] Furthermore, the evacuation lifeboat launching device of this utility model can not only assist in launching lifeboats, but also adapt to other types of hulls by changing the parameters of the connecting mechanism 5 and the pulley 8, and assist in launching other types of hulls according to their characteristics, thereby effectively guiding and protecting other types of hulls during launching and improving launching efficiency.
[0031] In one embodiment, for the lifeboat 2, electric winch 4, and connecting mechanism 5 described above, the connecting mechanism 5 includes a first connecting component 501 disposed at one end of the rope on the electric winch 4; the connecting mechanism 5 also includes a second connecting component 502 disposed on one side of the side plate of the lifeboat 2; the first connecting component 501 and the second connecting component 502 have the same structure, and the first connecting component 501 and the second connecting component 502 are arranged axially symmetrically; the first connecting component 501 includes a connecting handle 5011 disposed at one end of the rope on the electric winch 4, a pull pin 5012 disposed at the middle of the top of the connecting handle 5011, and a limiting plate 5013 cooperating with the connecting handle 5011 disposed on one side of the pull pin 5012; the connecting handle A pin 5014 is provided on one side of the top of 5011. A hook 5015 that cooperates with the connecting handle 5011 is provided on the outside of the pin 5014. The top of the hook 5015 has a groove 5016 that cooperates with the limiting plate 5013. The hook 5015 is C-shaped. The pin 5014 is located in the middle of the hook 5015. The groove 5016 is located at the top of one end of the hook 5015, thereby making a simple and stable connection between the electric winch 4 rope and the lifeboat 2. When subjected to external impact, the connection of the connecting mechanism 5 will not break or loosen, providing effective protection for the lifeboat 2. When it is necessary to untie, it can be easily disassembled by pulling the pin 5012, improving the launching efficiency of the lifeboat 2.
[0032] The working principle of the lifeboat 2, electric winch 4, and connecting mechanism 5 is as follows: When it is necessary to connect the electric winch 4 rope to the lifeboat 2, the operator brings the first connecting component 501 and the second connecting component 502 close to each other. Under the action of the pivot pin 5014, one hook 5015 will rotate around the midpoint under the push of the other hook 5015 and enter the connecting handle 5011 of the other. When the hook 5015 rotates to a certain angle, the limiting plate 5013 on one side of the pull pin 5012 will enter the groove 5. In step 016, the limiting plate 5013 restricts the two hooks 5015, thus securing the connection between the electric winch 4 rope and the lifeboat 2. When it is necessary to disconnect the electric winch 4 rope and the lifeboat 2, the operator only needs to pull up the pull pin 5012, and the limiting plate 5013 will move away from the groove 5016. At this time, the limiting plate 5013 releases the restriction on the two hooks 5015, and the operator applies opposing forces to the connecting handles 5011 on both sides, thereby disconnecting the connection between the electric winch 4 rope and the lifeboat 2.
[0033] In one embodiment, for the aforementioned inclined plate 1, limiting mechanism 6, and slide rail 7, the inclined plate 1 has an internal placement groove 9 that cooperates with the limiting mechanism 6. T-shaped blocks 10 cooperating with the limiting mechanism 6 are symmetrically arranged at the bottom end of the placement groove 9, and several limiting slide grooves 11 cooperating with the slide rail 7 are arranged at the top end of the placement groove 9. The limiting mechanism 6 includes a first sliding plate 601 and a second sliding plate 602 symmetrically arranged inside the placement groove 9. A first rack 603 is symmetrically arranged at both ends of one side of the first sliding plate 601, and a cylinder 604 is arranged on the other side of the first sliding plate 601. A second rack 605 is symmetrically arranged at both ends of one side of the second sliding plate 602. Both ends of one side of the first sliding plate 601 and the second sliding plate 602 are... Symmetrical grooves 606 are provided; the bottom ends of the first slide plate 601 and the second slide plate 602 are each provided with a T-shaped slide rail 607 that cooperates with the T-shaped block 10; the top ends of the first slide plate 601 and the second slide plate 602 are each provided with a slide rail 7; the first rack 603 and the second rack 605 both cooperate with the grooves 606; a gear 608 is provided between the first rack 603 and the second rack 605, and the gear 608 is connected to the placement groove 9 through a rotating shaft. The gear 608 meshes with the first rack 603 and the second rack 605, so that the slide rail 7 can adapt to lifeboats 2 of different specifications and guide and limit the lifeboat 2 to prevent the life-saving device on the lifeboat 2 from tilting when it is launched into the water, thus delaying the rescue opportunity.
[0034] It should be noted that in specific applications, the first rack 603, the second rack 605, the gear 608, and the rotating shaft can all be made of 304 or 316 stainless steel. Furthermore, galvanizing or adding an anti-corrosion coating can enhance their waterproof and rust-proof properties.
[0035] The working principle of the inclined plate 1, the limiting mechanism 6, and the slide rail 7 is as follows: Under the action of the external controller, the operator controls and starts the cylinder 604. Under the action of the extension of the output end of the cylinder 604, the first sliding plate 601 at both ends moves to the right. Under the limiting action of the T-shaped slide rail 607 and the T-shaped block 10, the first sliding plate 601 moves stably to the right. The movement of the first sliding plate 601 to the right drives the first rack 603 to move to the right. Under the cooperation of the rotating shaft, the gear 608, and the slide groove 606, the movement of the first rack 603 to the right drives the second rack 605 to move to the left. The movement of the second rack 605 to the left... During the movement, the second slide plate 602 moves to the left. Under the limiting action of the T-shaped slide 607 and the T-shaped block 10, the second rack 605 moves steadily to the left. Under the action of the limiting slide groove 11, the first slide plate 601 moves to the right and the second slide plate 602 moves to the left. During the movement, the two slides 7 move steadily to the left and right respectively, which reduces the distance between the two slides 7. When the pulley 8 is in contact with the lifeboat 2, under the action of the external controller, the operator controls and stops the cylinder 604. At this time, the limiting mechanism 6 forms a guiding and limiting effect on the lifeboat 2 to prevent the lifeboat 2 from capsizing.
[0036] Conversely, under the action of the external controller, the operator controls and starts the cylinder 604. Under the shortening action of the output end of the cylinder 604, the first slide plate 601 at both ends moves to the left. The leftward movement of the first slide plate 601 drives the first rack 603 to move to the left. The leftward movement of the first rack 603 drives the second rack 605 to move to the right. During the rightward movement of the second rack 605, the second slide plate 602 moves to the right. During the leftward movement of the first slide plate 601 and the rightward movement of the second slide plate 602, the two slide rails 7 move steadily to the right and left respectively, increasing the distance between the two slide rails 7 until they are reset. Under the action of the external controller, the operator controls and stops the cylinder 604. At this time, the limiting mechanism 6 releases its guiding and limiting effect on the lifeboat 2.
[0037] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.
[0038] In practical application, when lifeboat 2 needs to be launched, the operator controls and starts cylinder 604 under the action of an external controller. The extension of the output end of cylinder 604 drives the two slide rails 7 to move stably to the left and right respectively, reducing the distance between them. When pulley 8 is in contact with lifeboat 2, the operator controls and stops cylinder 604 under the action of the external controller (the specific working principles of inclined plate 1, limiting mechanism 6, and slide rails 7 are as described above). Then, the operator pulls up pin 5012, and the limiting plate 501... 3 will move away from the groove 5016. At this time, the limiting plate 5013 releases the restriction on the two hooks 5015. The operator applies opposing forces to the connecting handles 5011 on both sides, thereby untying the connection between the electric winch 4 rope and the lifeboat 2 (the specific working principles of the lifeboat 2, electric winch 4 and connecting mechanism 5 are as described above). Under the action of gravity and the inclined plate 1, the lifeboat 2 goes into the water along the slide 7. When the lifeboat 2 is not needed, the operator brings the first connecting component 501 and the second connecting component 502 closer together, and the axle pin 5014 acts as a pivot. When in use, one hook 5015 will rotate around the midpoint under the push of the other hook 5015 and enter the connecting handle 5011 of the other. When the hook 5015 rotates to a certain angle, the limiting plate 5013 on one side of the pull pin 5012 will enter the groove 5016. At this time, the limiting plate 5013 forms a limit between the two hooks 5015, thereby realizing a firm connection between the electric winch 4 rope and the lifeboat 2 (the specific working principle of the lifeboat 2, electric winch 4 and connecting mechanism 5 is as described above). Under the action of the winch 4, the lifeboat 2 is pulled up onto the ramp 1 along the slide 7. Under the action of the external controller, the operator controls and starts the cylinder 604. Under the action of the shortening of the output end of the cylinder 604, the two slides 7 are driven to move steadily to the right and left respectively, so that the distance between the two slides 7 is increased until they are reset. Under the action of the external controller, the operator controls and stops the cylinder 604. At this time, the limiting mechanism 6 releases the guiding and limiting effect on the lifeboat 2 (the specific working principle of the ramp 1, the limiting mechanism 6 and the slide 7 are as described above).
[0039] In summary, by utilizing the above-mentioned technical solution of this utility model, the present utility model, through the combined action of the inclined plate 1, the electric winch 4, the connecting mechanism 5, the limiting mechanism 6, and the slide rail 7, achieves a simple and stable connection between the electric winch 4 rope and the lifeboat 2. Simultaneously, the slide rail 7 can accommodate lifeboats 2 of different specifications and guides and limits the lifeboat 2, preventing the life-saving devices on the lifeboat 2 from tilting during launch, thus improving launch efficiency and timeliness of rescue. Under the action of the connecting mechanism 5, the electric winch 4 rope... The connection between the lifeboat 2 and the lifeboat 3 is simple and stable. When subjected to external impact, the connection of the connection mechanism 5 will not break or loosen, providing effective protection for the lifeboat 2. When it is necessary to disassemble, it can be easily disassembled by pulling the pin 5012, which improves the launching efficiency of the lifeboat 2. With the cooperation of the inclined plate 1, the limiting mechanism 6 and the slide 7, the slide 7 can adapt to lifeboats 2 of different specifications and guide and limit the lifeboat 2, preventing the life-saving devices on the lifeboat 2 from tilting during launching and delaying the rescue opportunity.
