Description

TECHNICAL FIELD

[0001] The present application relates to the field of ship lifesaving equipment and storage technology, in particular to a marine boarding rope ladder storage and quick release module. BACKGROUND

[0002] The boarding rope ladder refers to the rope ladder used by the personnel on the ship to board the lifeboat or raft in the event of an emergency. The boarding rope ladder is used for personnel to get on and off the ship or to evacuate personnel in emergency situations. Such rope ladders need to be strong enough to be safe to use in all weather conditions and to meet relevant maritime safety standards.

[0003] The traditional boarding rope ladder storage and release device currently on the market for use with life rafts is generally a separate device, including: a boarding rope ladder base, a safety handrail, a rope ladder binding eye ring, a rope ladder binding device, and a rope ladder wear-resistant material, a total of five independent parts. For example, patent application No. CN201711396285.5 discloses a boarding rope ladder storage device and storage method, which includes an eye plate and a base. The base is a symmetrical structure and is arranged on the deck. The eye plate is two, and the two eye plates are arranged on the front of the base and are symmetrical with the symmetry axis of the base. The base, handrail, eye plate, and wear-resistant pipe are all independent components, which are independently installed on the deck. During installation, the installation coordination distance and installation position between each component need to be measured, and the installation and construction are relatively complex.

[0004] Patent application No. CN202010391111.5 discloses a rope ladder storage rack, which includes a rectangular planar base with a frame structure. A plurality of hooks for buckling with a screw shackles are fixedly connected to the frame edges of the planar base. A railing for the rope ladder to abut is arranged on one side and / or both sides of the planar base in the length direction. This device is a storage base for the boarding rope ladder. The rope ladder is reeled in the storage rack when not in use, and is taken out of the storage rack for use when needed. This device still needs to be used with a safety handrail, a binding eye ring, and a rope ladder wear-resistant device in the application on the ship, resulting in that the device cannot integrate all functions and the installation is still relatively complex.

[0005] In summary, the boarding rope ladder requires the installation of a boarding rope ladder base, a safety handrail, a rope ladder binding eye ring, a rope ladder binding device, and a rope ladder wear-resistant material to be used together. The installation requires the construction site on the deck of the ship to be positioned respectively, and the five parts need to be positioned and assembled to form a complete boarding rope ladder storage and release device. This traditional boarding rope ladder storage device has high manufacturing cost, complicated installation, and large space occupation. Some ships with small deck space cannot normally arrange the device, 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.

[0006] In view of the above, it is necessary to propose a marine boarding rope ladder storage and rapid release module to solve the above problems. SUMMARY

[0007] The purpose of the present application is to overcome the defects existing in the prior art, and to provide a marine boarding rope ladder storage and rapid release module.

[0008] To achieve the above purpose, the technical scheme of the present application is as follows: a marine boarding rope ladder storage and rapid release module, which integrates a rope ladder base, a safety handrail, a binding eye ring, a binding device, and a rope ladder wear-resistant device into an integral module;

[0009] The rope ladder base includes a rectangular base frame mounted on the deck, and a plurality of inner support rods are arranged on the inner side of the base frame, so that the rope ladder base forms a grid-shaped base plane that can accommodate the boarding rope ladder or allow personnel to pass through;

[0010] The safety handrails are specifically arranged on both sides of the long sides of the base frame, and the two safety handrails and the rope ladder base form a concave space for accommodating the boarding rope ladder, and the two safety handrails laterally limit the boarding rope ladder accommodated therein to prevent it from falling over;

[0011] The binding eye ring is arranged at the entrance and exit end of the base frame, and the end of the boarding rope ladder is connected to the binding eye ring;

[0012] The binding device is distributed around the base frame to form base points for fixing the binding ropes, and the binding ropes are knotted to the boarding rope ladder by passing through the binding device to form multiple-point fixation to the boarding rope ladder;

[0013] The rope ladder wear-resistant device is arranged at the front edge of the entrance and exit end of the base frame, and the ladder rope is placed on it when the boarding rope ladder is released, so that the ladder rope avoids the relatively sharp ship side edge.

[0014] Further, the base frame is formed by welding angle steels into a rectangular frame, the inner support rods are made of square steels, a plurality of inner support rods are arranged in parallel and at intervals along the short side direction of the base frame, and the edges of the square steels are upward, forming a square steel fence inside the base frame; the base frame further includes frame feet, and a plurality of frame feet are arranged at the bottom of the base frame to form supports, so that a spacing is formed between the base frame and the deck.

[0015] Further, the safety handrails are designed asymmetrically, one side of the safety handrail is designed as a full-length handrail along the length direction of the base frame, and the other side of the safety handrail is designed as a half-length handrail.

[0016] Further, the binding eye ring includes ship eye rings symmetrically arranged on both sides of the entrance and exit end, which includes a ring seat and a ring body, the ring seat is fixedly arranged on the base frame, and the ring body is connected to the ring seat by a chain ring, and the ring body is the mounting connection point of the boarding rope ladder.

[0017] Furthermore, the binding device is a J-shaped rope hook, with two rope hooks on each side of the base frame, and the openings of the rope hooks are facing downwards.

[0018] Furthermore, the anti-wear device for the rope ladder is made of round steel, which is welded to the edge of the angle steel at the inlet and outlet, so that the circumference of the round steel is tangent to the upper end face of the angle steel.

[0019] Furthermore, the rope ladder anti-wear device includes two extended side plates that are forwardly arranged on both sides of the entrance and exit ends, and a fixed shaft is connected between the two extended side plates. A sleeve is fitted on the fixed shaft, and the sleeve is rotatably connected relative to the fixed shaft. When climbing the rope ladder, the ladder rope is wound around the sleeve.

[0020] Furthermore, the sleeve has axial movement allowance relative to the fixed shaft, and a rotating support is provided between the fixed shaft and the sleeve. At least two sets of rotating supports are provided on the fixed shaft. The rotating support has an inner ring and an outer ring. The inner ring of the rotating support is rotatably connected to the fixed shaft, and multiple support rollers are distributed circumferentially on the outer ring. The support rollers are rotatably mounted on the rotating support, and the rotation axis of the support rollers is perpendicular to the fixed shaft. The multiple support rollers are rolled on the inner wall of the sleeve.

[0021] Furthermore, the outer wall of the sleeve is formed with multiple shallow annular grooves that cooperate with the ladder rope.

[0022] Furthermore, the extended side panels on both sides are retractable and adjustable or can be rotated and folded for storage and adjustment.

[0023] The advantages and beneficial effects of this invention are as follows: This invention provides a shipboard boarding rope ladder storage and quick release module, which adopts a modular design, integrating rope ladder storage, securing, quick release, and rapid escape into one unit. This module effectively integrates and optimizes the five main parts of traditional boarding rope ladder storage and release devices, reducing the number of parts, allowing for one-time overall installation, occupying minimal deck space, and facilitating safe and rapid passage for personnel during escape. It uses less material, has high reliability, and its manufacturing and installation costs are lower than traditional devices. The rope ladder base within the module is designed as part of an escape route, facilitating faster, more reliable, and safer personnel escape. Attached Figure Description

[0036] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0037] Example 1:

[0038] A storage and quick-release module for a shipboard boarding rope ladder, comprising an integrated module 6 consisting of a rope ladder base 1, a safety handrail 2, binding eye rings 3, binding device 4, and a rope ladder anti-abrasion device 5; Figure 1As shown, this integrated module 6 combines various components required for rope ladder storage and release. Compared to traditional separate installation methods, this embodiment greatly simplifies the installation process on the ship's deck, reduces the number of parts, facilitates one-time installation, uses less material, and offers high reliability. The module is 1400mm long, 700mm wide, and has a base height of 215mm, with a total height of 1065mm including the handrails. It also minimizes deck space occupation, making it highly adaptable and suitable for installation and use on most steel-hulled seagoing vessels currently on the market. The left side of the module features a full handrail design, while the right side has a half-handrail design. After completion, the module undergoes hot-dip galvanizing to improve its corrosion resistance.

[0039] The rope ladder base 1 includes a rectangular base frame installed on the deck. The base frame has several inner support rods 7 on its inner side, so that the rope ladder base 1 forms a grid-like base plane that can accommodate the climbing rope ladder or allow people to pass through.

[0040] Specifically, the base frame is constructed by welding angle steel to form a rectangular frame. In practice, 75×50×6 angle steel is used to weld the rectangular frame. The inner support rod 7 is made of square steel, such as... Figure 5 , 6 As shown, several internal support rods 7 are arranged parallel to each other along the short side of the base frame, with the edges of the square steel facing upwards. This upward-facing arrangement prevents water stains from remaining on the upper surface and causing corrosion during long-term use. Square steel faceplates 9 are formed within the base frame, and the arranged square steels, together with the upper surface of the base frame, form a plane for housing the rope ladder base 1. Figure 2 , 3 As shown, once the climbing rope ladder is retracted, it can be stacked on the square steel faceplate 9 and then secured with ropes. The base frame also includes frame legs 10, with multiple frame legs 10 respectively positioned at the bottom of the base frame to form a support, creating a gap between the base frame and the deck. In this embodiment, since the entire structure is treated as a module, it can be easily installed in one go. The frame legs 10 can be welded to the ship's deck, making fixation convenient. Furthermore, the frame legs 10 effectively support the rope ladder base 1, preventing waterlogging and corrosion.

[0041] The binding device 4 is distributed around the base frame to form base points for fixing the binding rope. When binding the climbing rope ladder, the rope passes through the binding device 4 to form multi-point fixation of the climbing rope ladder. Specifically, the binding device 4 is a J-shaped rope hook 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 set downwards. Figure 2 , 3 As shown, the climbing rope ladder can be secured by binding ropes in a crisscross pattern, both horizontally and vertically.

[0042] Safety handrails 2 are specifically installed on both sides of the long side of the base frame. The safety handrails 2 on both sides and the rope ladder base 1 form a concave space to accommodate the climbing rope ladder. The safety handrails 2 on both sides laterally limit the climbing rope ladder housed therein to prevent it from tipping over; Figure 2 , 3 As shown in Figure 7, when the climbing rope ladder is placed inside the rope ladder base 1, due to the large number of turns of the rope ladder, it accumulates a certain height. In this embodiment, the safety handrails 2 on both sides are positioned to block the rope ladder, providing lateral support and preventing it from tipping over. This also helps to facilitate the quick release of the climbing rope ladder. Furthermore, as... Figure 1 , 5 As shown in Figure 6, the safety handrail 2 has an asymmetrical design. One side of the safety handrail 2 is designed as a full-length handrail 11 along the length of the base frame, while the other side is designed as a partial handrail 12. In actual use, the rope ladder base 1 of this overall module 6 can be used as part of the escape route. In this embodiment, the asymmetrical handrail design facilitates personnel to enter the rope ladder base 1 from the space left by the partial handrail 12, thereby increasing the range of angles that personnel can access.

[0043] The eyelet 3 is located at the entrance / exit end 8 of the base frame, and the end of the rope ladder is connected to the eyelet 3; for example... Figure 1 , 2 As shown in Figure 5, the binding eye ring 3 includes marine eye rings symmetrically arranged on both sides of the entrance / exit end 8. Each eye ring includes a ring seat 13 and a ring body 14. The ring seat 13 is fixedly mounted on the base frame, and the ring body 14 is connected to the ring seat 13 by a chain link. The ring body 14 serves as the installation connection point for the boarding rope ladder. The end of the boarding rope ladder has two rope ends for connecting to the ring body 14, which can be connected using shackles for convenient installation and disassembly. When the boarding rope ladder is extended, it can be fixed to this module via the binding eye ring 3, thereby securing it to the hull.

[0044] The rope ladder anti-abrasion device 5 is located at the front edge of the entrance / exit end 8 of the base frame. Entrance / exit end 8 is the entrance / exit for personnel to climb the rope ladder from the outside or exit via the rope ladder base 1. When the rope ladder is deployed, the ladder rope rests on it, preventing it from crossing the relatively sharp edges of the ship's side. Since the rope ladder is released from entrance / exit end 8, without this anti-abrasion device, some of the ladder rope will inevitably get stuck on the outer plating of the ship's side. As personnel climb, the ladder rope is repeatedly stretched and contracted, and with the help of waves, it rubs against the outer plating of the ship's side, easily causing it to break. Specifically, for example... Figure 1 , 2As shown in Figure 4, in this embodiment, the anti-wear device 5 for the rope ladder is a round steel bar 16. The round steel bar 16 is welded to the edge of the angle steel at the inlet / outlet end 8, so that the circumference of the round steel bar 16 is tangent to the upper end face of the angle steel. During installation, it is advisable to expose a portion of the round steel bar 16 on the outer side plate, thereby avoiding wear of the ladder rope on the outer side plate. The round steel bar 16 is tangentially connected to the edge of the angle steel of the base frame and is ground smooth, which greatly reduces wear on the ladder rope.

[0045] This device adopts a modular, integrated design, featuring a simple structure and minimal material usage. Its overall manufacturing and installation costs are lower than traditional bulky rope ladder storage and deployment devices. Occupying only 1400×700×1065 mm (including handrail height), it is highly adaptable and can meet the installation and usage requirements of most steel-hulled seagoing vessels currently on the market. The rope ladder base 1 within the module is designed as part of an escape route, facilitating rapid, reliable, and safer evacuation.

[0046] Example 2:

[0047] In the aforementioned embodiments, the fixed rope ladder anti-wear device 5 made of round steel 16, while having some effect, still maintains frictional contact between the ladder rope and the round steel 16, resulting in significant wear on the ladder rope. This embodiment, as an improvement, changes the frictional contact to rolling contact, thereby greatly reducing wear on the ladder rope. Specifically, as shown... Figure 8 As shown, the rope ladder anti-wear device 5 includes two extended side plates 17 extending forward on both sides of the entrance / exit end 8. These two extended side plates allow the rope ladder anti-wear device 5 to extend beyond the outer side plate, ensuring that the rope ladder maintains a certain distance from the outer side plate when it is fully deployed, facilitating climbing. Furthermore, as... Figure 9 As shown, a fixed shaft 18 is connected between the two extended side plates 17. A sleeve 19 is fitted onto the fixed shaft 18, and the sleeve 19 is rotatably connected relative to the fixed shaft 18. When the rope ladder is released, it is wound around the sleeve 19. In use, when the rope passes over the sleeve 19, the rotation of the sleeve 19 relative to the fixed shaft 18 can change the frictional contact into rolling contact, further protecting the integrity of the rope.

[0048] Example 3:

[0049] In Embodiment 2, a sufficient gap must be left between the sleeve 19 and the fixed shaft 18 to facilitate rotation. However, this results in an excessive gap between the sleeve 19 and the fixed shaft 18, which easily generates significant shaking noise. Furthermore, under the pressure of the ladder rope, the sleeve 19 is easily pressed tightly against the fixed shaft 18, reducing the rotation efficiency of the sleeve 19. Secondly, while changing sliding contact to rolling contact improves the protection of the ladder rope, factors such as ocean waves cause the ladder to sway back and forth, leading to the ladder rope moving relative to the sleeve 19 in the front-to-back direction, which still causes some wear on the ladder rope. To overcome this problem, as an improvement, the sleeve 19 has an axial movement allowance relative to the fixed shaft 18, such as... Figure 10 As shown, a rotating support 20 is provided between the fixed shaft 18 and the sleeve 19. In this embodiment, two sets of rotating support 20 are schematically set on the fixed shaft 18, but more can be added as needed. The rotating support 20 has an inner ring 21 and an outer ring. The inner ring 21 of the rotating support 20 is rotatably connected to the fixed shaft 18. Multiple support rollers 22 are distributed circumferentially on the outer ring. The support rollers 22 are rotatably mounted on the rotating support 20, and the rotation axis of the support rollers 22 is perpendicular to the fixed shaft 18. The multiple support rollers 22 are rolled on the inner wall of the sleeve 19. By rotating the inner ring 21 of the rotating support 20 to the fixed shaft 18, the rotating support 20 can rotate freely. The support rollers 22 arranged on the outer ring can provide axial movement for the sleeve tube 19. In use, because 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 tightly on the fixed shaft 18 by the ladder rope and unable to rotate. Thus, the sleeve tube 19 can rotate flexibly. Since the outer ring rolls in 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 19, the axial elongation caused by tensile force or the back-and-forth swinging caused by lateral force can be converted into circumferential rotation or axial movement of the sleeve 19, thereby completely avoiding wear on the ladder rope and achieving better performance.

[0050] Furthermore, the outer wall of the sleeve tube 19 is formed with multiple shallow annular grooves 23 that cooperate with the ladder rope. In actual use, when the ladder is released, the ladder rope can be randomly inserted into any two shallow annular grooves 23, thereby positioning the ladder rope and the sleeve tube 19 in a relative axial position and preventing the ladder rope from rubbing against the sleeve tube 19.

[0051] Example 4:

[0052] In embodiment three, to maintain a certain distance between the deployed boarding rope ladder and the outer side plating, the extended side plate 17 extends a certain distance overboard. This increases the lateral width of the hull. As an improvement, the extended side plates 17 on both sides are retractable or foldable for storage and adjustment. Designing the extended side plates 17 as retractable allows them to extend overboard when needed and retract inboard when not in use, thus avoiding an increase in hull width. As another embodiment, such as... Figure 11 As shown, the extended side plate 17 is designed to be folded and stored. When stored, it folds upward and blocks the outer end of the boarding rope ladder, which can also serve to limit its movement. When the extended side plate 17 is lowered, it can be directly clipped onto the outer side plate of the hull for fixation, allowing the sleeve tube 19 to extend outside the hull, making it convenient to use.

[0053] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
