Description

Technical Field

[0001] The invention relates to the technical field of ship lifesaving equipment and storage, and in particular to a storage and quick-release module for a ship boarding rope ladder. Background Art

[0002] A boarding ladder is a ladder used by shipboard personnel to board a lifeboat or raft in an emergency. It is used to board or disembark personnel or to evacuate personnel in an emergency. Such ladders need to be strong enough to be used safely in all weather conditions and meet relevant maritime safety standards.

[0003] At present, the traditional boarding rope ladder storage and release devices used in conjunction with life rafts on the market are generally independent devices, including: a boarding rope ladder base, a safety handrail, a rope ladder tying eye ring, a rope ladder tying device, and a rope ladder anti-wear material, a total of 5 independent parts. For example, patent application number: CN201711396285.5 discloses a storage device and storage method for a boarding rope ladder, the storage device of the boarding rope ladder includes an eye plate and a base, the base is a symmetrical structure, and is arranged on the deck, the eye plates are two, and the two eye plates are arranged in front of the base and are symmetrical about the symmetry axis of the base. Its base, handrail, eye plate, and anti-wear circular tube are all independent components, which are installed separately on the deck. During installation, it is necessary to measure the installation matching distance and installation position between each component, the deck space is large, and the installation construction is relatively complicated.

[0004] Another patent application number: CN202010391111.5 discloses a rope ladder storage rack, including a rectangular plane base with a frame structure, a plurality of hooks for engaging with spiral shackles are fixedly connected to the edge of the frame of the plane base, and railings for the rope ladder to lean against are arranged on one side and / or both sides of the plane base in the length direction. The device is a storage base for the boarding rope ladder. The rope ladder is rolled up in the storage rack when not in use, and the rope ladder is taken out of the storage rack when needed. In the application of ships, the device still needs to be used in combination with safety handrails, lashing eyelets, and rope ladder anti-wear equipment, resulting in the device failing to integrate all functions and the installation is still relatively complicated.

[0005] In summary, the setting of the boarding rope ladder requires the installation of five parts, namely the boarding rope ladder base, safety handrail, rope ladder lashing eye ring, rope ladder lashing device, and rope ladder anti-wear material, before it can be used. Its installation requires the construction site on the hull deck to be positioned separately, and the five parts must be positioned and assembled separately to form a complete set of boarding rope ladder storage and release devices. This traditional boarding rope ladder storage device has high production costs, cumbersome installation, and occupies a large space. Some ships with smaller deck space often cannot be arranged normally, and there is a gap of more than 500mm between the rope ladder base and the rope ladder, which is not conducive to the rapid escape of personnel.

[0020] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0021] Embodiment 1: A ship-mounted boarding rope ladder storage and quick release module, which integrates a rope ladder base 1, a safety handrail 2, a lashing eye ring 3, a lashing device 4, and a rope ladder anti-wear device 5 into an integral module 6; Figure 1 As shown, the overall module 6 integrates various components required for rope ladder storage and release. Compared with the traditional separate settings and installation modes, this embodiment greatly simplifies the steps of installing the device on the hull deck, reduces the number of parts, and is convenient for one-time installation. The overall production uses less materials and has high reliability. The total length of the module is 1400mm, the width is 700mm, the base height is 215mm, the total height including the handrail is 1065mm, and the deck space occupancy is reduced. Therefore, it has strong adaptability and can meet the installation and use of most steel ships on the market. The left side of the module adopts a full handrail design, and the right side is a half-handrail 12 design. After the module is completed, it is hot-dip galvanized as a whole to improve its corrosion resistance.

[0022] The rope ladder base 1 comprises a rectangular base frame installed on the deck, and a plurality of inner support rods 7 are arranged inside the base frame, so that the rope ladder base 1 forms a grid-like base plane that can store the boarding rope ladder or allow people to pass; Specifically, the base frame is welded with angle steel to form a rectangular frame. In specific implementation, 75×50×6 angle steel is welded to form a rectangular frame. The inner support rod 7 is made of square steel, such as Figure 5 , 6 As shown, a plurality of inner support rods 7 are arranged in parallel and spaced apart along the short side direction of the base frame, and the edges of the square steel are facing upwards, which can prevent water stains from remaining on the upper plane and causing corrosion during long-term use; a square steel surface stop 9 is formed in the base frame, and the arranged square steels and the upper plane of the base frame form a plane for storing the rope ladder base 1, as shown in FIG. Figure 2 , 3 As shown, when the boarding rope ladder is rolled up, it can be stacked on the square steel surface block 9, and then fixed by tying ropes; the base frame also includes frame support feet 10, and multiple frame support feet 10 are respectively arranged at the bottom of the base frame to form a support, so that a spacing space is formed between the base frame and the deck. In this embodiment, since the whole is used as a module, it can be easily installed at one time, and can be welded on the hull deck through the frame support feet 10, which is convenient for fixing; and the rope ladder base 1 is supported by the frame support feet 10 to effectively drain water and avoid soaking and rusting.

[0023] The tying devices 4 are distributed around the base frame to form base points for the tying ropes to be fixed. When the tying ropes are tied to the boarding rope ladder, they pass through the tying devices 4 to form multi-point fixation for the boarding rope ladder. Specifically, the tying devices 4 are J-shaped rope hooks 15. In this embodiment, two rope hooks 15 are provided on each side of the rope ladder base 1, and the openings of the rope hooks 15 are arranged downward. Figure 2 , 3 As shown, the wound and stored boarding rope ladder can be tied and fixed in a transverse and longitudinal staggered manner by means of binding ropes.

[0024] The safety handrails 2 are specifically arranged on both sides of the long sides of the base frame. The safety handrails 2 on both sides and the rope ladder base 1 form a concave space for accommodating the boarding rope ladder. The safety handrails 2 on both sides limit the boarding rope ladder stored therein to prevent it from tipping over; Figure 2 , 3 As shown in FIG. 7 , when the boarding rope ladder is placed in the rope ladder base 1, the rope ladder has a large number of windings, thereby accumulating a certain height. In this embodiment, the safety handrails 2 on both sides just block the two sides of the rope ladder, providing lateral support to prevent the rope ladder from tipping over, and can assist in quickly releasing the boarding rope ladder. Further, as Figure 1 , 5As shown in Figures 6 and 7, the safety handrail 2 is asymmetrically designed, with one side of the safety handrail 2 being designed as a full-length handrail 11 along the length direction of the base frame, and the other side of the safety handrail 2 being designed as a half-length handrail 12. In actual use, the rope ladder base 1 of the overall module 6 can be used as part of an escape passage. In this embodiment, the asymmetrical handrail is designed to facilitate personnel to enter the rope ladder base 1 from a portion of the space vacated by the half-length handrail 12, thereby increasing the angle range that personnel can enter.

[0025] The lashing eyelet 3 is arranged at the access end 8 of the base frame, and the end of the boarding rope ladder is connected to the lashing eyelet 3; Figure 1 , 2 As shown in Figure 5, the lashing eye 3 includes a marine eye symmetrically arranged on both sides of the access end 8, which includes a ring seat 13 and a ring body 14. The ring seat 13 is fixedly arranged on the base frame, and the ring body 14 is connected to the ring seat 13 by a chain ring. The ring body 14 is the installation connection point of the boarding rope ladder. The end of the boarding rope ladder has two ladder rope ends for connecting with the ring body 14, which can be connected by a shackle to achieve the purpose of convenient installation and disassembly. When the boarding rope ladder is released, it can be fixed to this module through the lashing eye 3, so as to be fixed to the hull.

[0026] The rope ladder anti-wear device 5 is arranged at the front edge of the entrance and exit end 8 of the base frame. The entrance and exit end 8 is the entrance and exit for people to enter by climbing the rope ladder from the outside, or for people to leave from the rope ladder base 1 through the boarding rope ladder. When the boarding rope ladder is released, the ladder rope is placed on it so that the ladder rope avoids the relatively sharp edge of the ship's side. Since the boarding rope ladder is released from the entrance and exit end 8, if the anti-wear device is not provided, it is inevitable that part of the ladder rope will be stuck on the side outer plate. When people climb up, the ladder rope is repeatedly stretched and contracted, and accompanied by waves, the ladder rope rubs back and forth on the side outer plate, which is easy to cause the ladder rope to be worn off. Specifically, Figure 1 , 2 As shown in FIG. 4 , in this embodiment, the rope ladder anti-wear device 5 is a round steel 16, which is welded to the edge of the angle steel at the inlet and outlet end 8, so that the circumference of the round steel 16 is tangent to the upper end face of the angle steel. During installation, it is preferable to expose a portion of the round steel 16 from the side outer plate, so as to prevent the ladder rope from being worn on the side outer plate. The round steel 16 is tangently connected to the edge of the angle steel of the base frame and is polished and smooth, which greatly reduces the wear on the ladder rope.

[0027] The device adopts modular overall design, simple structure, low material consumption, and the overall production cost and installation cost are lower than the traditional bulk boarding rope ladder storage and placement device. It occupies a small space of only 1400×700×1065 (including handrail height), so it has strong adaptability and can meet the installation and use of most steel ships on the market. The rope ladder base 1 in the module is designed as a part of the escape passage, which is conducive to the rapid escape of personnel and is more reliable and safer.

[0028] Embodiment 2: In the above-mentioned embodiment, the fixed rope ladder anti-wear device 5 made of round steel 16 has a certain effect, but there is still frictional contact between the ladder rope and the round steel 16, which still causes great wear on the ladder rope. As an improvement, this embodiment changes the frictional contact into rolling contact, thereby greatly reducing the wear on the ladder rope. Specifically, Figure 8 As shown, the rope ladder anti-wear device 5 includes two extended side plates 17 arranged in front of both sides of the access end 8. The two extended side plates can extend the rope ladder anti-wear device 5 outside the side outer plate, so that when the boarding rope ladder is released, the rope ladder and the side outer plate maintain a certain distance, which is convenient for people to climb. Fig. 9 As shown, a fixed shaft 18 is connected between the two extended side plates 17, and a sleeve tube 19 is sleeved on the fixed shaft 18. The sleeve tube 19 is rotatably connected relative to the fixed shaft 18, and the ladder rope when the boarding rope ladder is released is wound around the sleeve tube 19. When in use, when the ladder rope passes around the sleeve tube 19, when the ladder rope is stretched and retracted under force, the friction contact can be converted into rolling contact by the rotation of the sleeve tube 19 relative to the fixed shaft 18, which further protects the integrity of the ladder rope.

[0029] Embodiment three: In the second embodiment, there must be sufficient clearance between the sleeve tube 19 and the fixed shaft rod 18 to facilitate rotation, which results in too much clearance between the sleeve tube 19 and the fixed shaft rod 18, which is prone to produce a large shaking noise; and under the pressure of the ladder rope, the sleeve tube 19 is easily pressed against the fixed shaft rod 18, resulting in a reduction in the rotation effect of the sleeve tube 19. Secondly, it improves the protection of the ladder rope by changing the sliding contact into rolling contact. However, with factors such as waves on the ocean, the boarding rope ladder will also have a certain forward and backward swing amplitude, thereby causing the ladder rope to move forward and backward relative to the sleeve tube 19, which will still cause certain wear on the ladder rope. In order to overcome this problem, as an improvement, specifically, the sleeve tube 19 has an axial movement margin relative to the fixed shaft rod 18, such as Fig.10As shown, a rotating support member 20 is provided between the fixed shaft 18 and the sleeve tube 19. In this embodiment, two groups of rotating support members 20 are schematically arranged on the fixed shaft 18, and can also be increased according to the situation. The rotating support member 20 has an inner ring 21 and an outer ring. The inner ring 21 of the rotating support member 20 is rotatably connected to the fixed shaft 18, and a plurality of supporting rollers 22 are distributed on the circumference of the outer ring. The supporting rollers 22 are rotatably arranged on the rotating support member 20, and the rotating axis direction of the supporting rollers 22 is perpendicular to the fixed shaft 18; a plurality of supporting rollers 22 are rollingly connected to the inner wall of the sleeve tube 19. The inner ring 21 of the rotating support 20 is connected to the fixed shaft 18 in rotation, so that the rotating support 20 can rotate freely, and the support rollers 22 arranged on the outer ring can provide the sleeve tube 19 with the ability to move axially. When in use, since the sleeve tube 19 is supported by the rotating support 20, the sleeve tube 19 and the fixed shaft 18 are coaxially arranged, avoiding the disadvantage of being pressed on the fixed shaft 18 by the ladder rope and unable to rotate, so that the sleeve tube 19 can rotate flexibly; since the outer ring is in rolling contact with the inner wall of the sleeve tube 19 through multiple support rollers 22, the sleeve tube 19 can move flexibly in the axial direction relative to the fixed shaft 18. It can be understood that the length of the fixed shaft 18 is slightly longer than that of the sleeve tube 19, so that the sleeve tube 19 has a certain axial movement stroke. When the ladder rope is mounted on the sleeve tube 19, the axial elongation caused by the tensile force, or the forward and backward swing of the ladder rope caused by the lateral force can be converted into the circumferential rotation or axial movement of the sleeve tube 19, thereby completely avoiding the wear of the ladder rope and achieving better use effect.

[0030] Furthermore, the outer wall of the sleeve tube 19 is formed with a plurality of shallow annular grooves 23 that match the ladder rope. In actual use, when the boarding rope ladder is released, the ladder rope can be randomly inserted into any two shallow annular grooves 23, so that the ladder rope and the sleeve tube 19 can be relatively positioned in the axial position to avoid friction of the ladder rope on the sleeve tube 19.

[0031] Embodiment 4: In the third embodiment, in order to keep a certain distance between the boarding rope ladder and the side outer plate, the extended side plate 17 is extended to a certain distance outside the side plate, thereby increasing the transverse width of the hull. As an improvement, the extended side plates 17 on both sides are retractable and adjustable or can be rotated, folded and stored. The extended side plates 17 are designed to be retractable and adjustable, that is, when they are needed, they are extended to the outside of the side plate, and when they are not used, they can be stored inside the side plate, thereby avoiding the increase of the hull width. As another embodiment, Fig.11 As shown, the extended side panel 17 is designed to be folded and stored. When stored, it folds upward to block the outer end of the boarding rope ladder, and can also limit it. When the extended side panel 17 is lowered, it can be directly clamped on the outer side panel for fixation, so that the sleeve tube 19 extends out of the ship, which is easy to use.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
