Description

Technical Field

[0001] The utility model relates to the technical field of ro-ro passenger ships, in particular to a floating emergency evacuation ladder for ro-ro passenger ships. Background Art

[0002] A ro-ro passenger ship, also known as a roll-on / roll-off ship, is a transport vessel that uses a tractor to pull a semi-trailer or wheeled pallet loaded with containerized or other piece goods directly into and out of the cargo hold for loading and unloading. The cargo carried by the passenger ro-ro ship enters and exits the cargo hold through its own power and can also carry passengers at the same time. It is mostly used for inland river ferries and medium and short-distance sea transportation. The passenger ro-ro ship developed and evolved from the car ferry. The passenger ro-ro ship has multiple decks to facilitate the placement of cargo units. It has a special shape. The upper deck is a flat plate surface with no hatches and no lifting equipment. With the development of the tourism industry, the frequency and number of passenger ro-ro ships have increased. If a failure occurs during transportation, passengers need to escape from the water. The height of the passenger ro-ro ship and the emergency rescue ship are not on the same level. In order to facilitate passenger escape, an emergency evacuation ladder needs to be installed on the passenger ro-ro ship to allow people to disembark smoothly. However, since the emergency evacuation ladder is usually installed next to the hull, the hull will also shake with the fluctuations of the water surface, making it difficult for people to grab the emergency evacuation ladder when in use, which may cause people to fall into the water. In addition, the emergency evacuation ladder is usually an integrated design, which makes it inconvenient to place it. Therefore, we propose a floating emergency evacuation ladder for passenger ro-ro ships. Utility Model Content

After straightening, the evacuation ladder component can withstand top-down pressure, and adjustment lowering ropes are connected in series on both sides of the evacuation ladder component, and the adjustment lowering ropes pass through the end of the evacuation ladder component away from the fixed mounting seat and are connected to the fixed mounting seat.

[0005] Optionally, the evacuation ladder component includes a plurality of connecting plates connected to each other, wherein the connecting plate at one end of the evacuation ladder component is connected to the positioning winding roller, one end of the connecting plate is overlapped on another connecting plate, and the end of the connecting plate close to the positioning winding roller is overlapped on the connecting plate adjacent to it.

[0006] Optionally, the connecting plate includes a platform support plate and a connecting shaft pin seat. The bottom of the platform support plate overlapped at the upper end is fixedly connected to the connecting shaft pin seat, and the connecting shaft pin seat is movably mounted on the lower end of the adjacent platform support plate overlapped.

[0007] Optionally, both sides of the platform support plate overlapped at one end below are fixedly connected with support rope rings, and the adjustment and lowering rope passes through the support rope rings.

[0008] Optionally, a lifting and winding wheel is movably mounted on the inner side of the fixed mounting seat, and the lifting and winding wheel is fixed to the adjusting and lowering rope.

[0009] Optionally, a transmission rod is connected to the fixed mounting seat via an axle pin, and the transmission rod and one end of the lifting and winding wheel extending into the fixed mounting seat are jointly sleeved with a pull rope transmission belt.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 to 6The evacuation ladder is a floating emergency evacuation ladder for a passenger ro-ro ship, comprising a fixed mounting base 1, which can be fixedly mounted on the passenger ro-ro ship. A positioning winding roller 11 is movably mounted on the fixed mounting base 1. The positioning winding roller 11 can be rotated at a fixed position on the fixed mounting base 1. An evacuation ladder component that can be wound around the outer side of the positioning winding roller 11 for storage is connected to the positioning winding roller 11. The evacuation ladder component can be retracted and released by rotating the positioning winding roller 11, thereby making it more convenient to use. After being retracted, its structure is more compact and centralized, reducing the space it occupies, thereby making it more convenient to store. The evacuation ladder component can withstand pressure from top to bottom after being straightened, thereby making it more convenient to use. The evacuation ladder can be carried by people, so that people can pass through the evacuation ladder component smoothly, thereby ensuring the smooth escape of people, and the adjustment lowering rope 3 is connected in series on both sides of the evacuation ladder component. By adjusting the lowering rope 3 and passing it through the support rope ring 8, the platform support plate 2 can be supported by pulling the adjustment lowering rope 3, thereby making its support more stable, and by pulling the adjustment lowering rope 3, the inclination angle of the bottom of the evacuation ladder component can be adjusted, thereby making it more convenient to use. The adjustment lowering rope 3 passes through the end of the evacuation ladder component away from the fixed mounting seat 1 and is connected to the fixed mounting seat 1, thereby being able to smoothly pull the evacuation ladder component so that it can be smoothly flattened.

[0025] See also Figures 1 to 5 The evacuation ladder component includes a plurality of connecting plates connected to each other, wherein the connecting plate at one end of the evacuation ladder component is connected to the positioning winding roller 11, and one end of the connecting plate is overlapped on another connecting plate, and the end of the connecting plate close to the positioning winding roller 11 is overlapped on the connecting plate adjacent to it, so that they can be overlapped, thereby supporting the people on them to escape, and under the action of the overlap, the plane on which the people walk can be in the shape of a broken line, thereby increasing the friction of the people walking, and preventing the smooth plane on which the people walk from slipping when it comes into contact with seawater.

[0026] See also Figures 1 to 6 The connecting plate includes a platform support plate 2 and a connecting shaft pin seat 9. The platform support plate 2 is overlapped at the bottom of one end thereof and is fixedly connected to a connecting shaft pin seat 9. The connecting shaft pin seat 9 and its adjacent platform support plate 2 are overlapped at one end thereof and are movable. The platform support plates 2 can rotate relative to each other with the connecting shaft pin seat 9 as the rotating axis to ensure that the platform support plates 2 can be bent smoothly during winding, so that the winding between the connecting plates can be completed smoothly.

[0027] See also Figures 1 to 6The platform support plate 2 is overlapped at one end at the bottom and is fixedly connected with a support rope ring 8 on both sides. Through the design of the position of the support rope ring 8, the adjustment and lowering rope 3 can pull and support the connection parts between the connecting plates to reduce the negative pressure at the connection between the connecting plates, thereby making it less likely to be damaged, thereby extending its service life, and adjusting the lowering rope 3 to pass through the support rope ring 8.

[0028] See also Figures 1 to 5 The inner side of the fixed mounting seat 1 is movably covered with a lifting and winding wheel 4, which can be rotated in a fixed position on the fixed mounting seat 1. Under the action of the rotation of the lifting and winding wheel 4, the adjustment and lowering draw rope 3 can be retracted and released. The lifting and winding wheel 4 is fixed to the adjustment and lowering draw rope 3, and a transmission rod 7 is connected to the fixed mounting seat 1 through an axle pin to form a hinge structure with the axle pin as the rotating axis, so that the transmission rod 7 can be rotated in a fixed position on the fixed mounting seat 1, and the transmission rod 7 and the lifting and winding wheel 4 extending into the fixed mounting seat 1 are jointly sleeved with a draw rope transmission belt 10. Driven by the transmission rod 7, the draw rope transmission belt 10 can rotate, and under the transmission of the draw rope transmission belt 10, the lifting and winding wheel 4 can rotate smoothly.

[0029] See also Figures 1 to 5 A first servo motor 5 is fixedly connected to the outer side of the fixed mounting seat 1, and the output shaft of the first servo motor 5 is fixedly installed on one end of the transmission rod 7. Driven by the output shaft of the first servo motor 5, the transmission rod 7 can rotate. The first servo motor 5 is an existing technology and no improvement is made here, so it will not be described in detail.

[0030] See also Figures 1 to 5 A second servo motor 6 is fixedly connected to the outer side of the fixed mounting seat 1, and the output shaft of the second servo motor 6 is fixedly installed on one end of the positioning winding roller 11. Driven by the output shaft of the second servo motor 6, the positioning winding roller 11 can rotate. The second servo motor 6 is the existing technology and no improvement is made here, so it will not be described in detail.

[0031] In summary, when the floating emergency evacuation ladder for passenger and vehicle ships is in use, the positioning winding roller 11 can be rotated under the drive of the output shaft of the second servo motor 6. Under the rotation of the positioning winding roller 11, the evacuation ladder components can be gradually lowered, and then the connecting plates can be unfolded. Thereafter, the transmission rod 7 can be rotated under the drive of the output shaft of the first servo motor 5. Under the rotation of the transmission rod 7, the rope transmission belt 10 can be transmitted, and under the transmission of the rope transmission belt 10, the lifting and winding wheel 4 can be rotated. Under the rotation of the lifting and winding wheel 4, the lowering rope 3 can be retracted and adjusted, and the evacuation ladder components can be pulled so that the connecting plates can overlap each other. At the same time, by adjusting the pulling of the lowering rope 3, the angle of the evacuation ladder components can be adjusted, thereby forming an emergency evacuation ladder.
