When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0039] According to a first aspect of an embodiment of the present invention, an inclined ladder is provided. Figures 1 to 8 Describe in detail the structure and working principle of the inclined ladder.

[0040] According to an embodiment of the present invention, the inclined ladder is used for a ship, and includes a ladder body 4, a handrail mechanism 1, and a hoisting member 7. In the embodiment, the ladder body 4 extends along a first direction, and the ladder body 4 includes a first end and a second end in the first direction, the first end is hinged to a first position of the ship, and the second end is detachably connected to a second position 6 of the ship.

[0041] In an embodiment, the armrest mechanism 1 includes a first armrest assembly and a second armrest assembly 2, the first armrest assembly and the second armrest assembly 2 are detachably connected along a first direction, the second armrest assembly 2 is close to the second end relative to the first armrest assembly, the second armrest assembly 2 is detachably connected to the first armrest assembly, the first armrest assembly is connected to a ladder body 4, and the second armrest assembly 2 is detachably connected to the ladder body 4.

[0042] In the embodiment, the hoisting member 7 is connected to the ladder body 4 , and the hoisting member 7 has a hoisting portion, and the hoisting portion is used to be hoisted so that the ladder body 4 pivots around the first position.

[0043] In this way, according to the inclined ladder provided by an embodiment of the present invention, the second handrail assembly 2 of the handrail mechanism 1 of the inclined ladder is detachably connected to the first handrail assembly, and the second handrail assembly 2 is detachably connected to the ladder body 4, thereby, the second handrail assembly 2 can be separated from the whole formed by the first handrail assembly and the ladder body 4, which is equivalent to the second handrail assembly 2 being able to be removed from the inclined ladder.

[0044] Since the second handrail assembly 2 is closer to the second end of the inclined ladder, when the inclined ladder needs to be hoisted, the second end of the ladder body 4 of the inclined ladder is disassembled from the second position 6 of the ship, and then the ladder body 4 is hoisted by connecting the external hoisting structure with the hoisting member 7. During the hoisting process, the ladder body 4 rotates around the hinged first position, and the removal of the second handrail assembly 2 leaves space above the side where the second end of the ladder body 4 is located, so that the side where the second end of the ladder body 4 is located can be raised to a sufficient height without interfering with other structures of the ship, thereby making the inclined ladder difficult to climb. In practical applications, it can slow down the pirates from reaching the cab, thereby gaining rescue time.

[0045] According to the anti-pirate inclined ladder for ships provided by the present invention, the second handrail assembly can be made reversible or detachable, and the ladder body can be lifted and fixed after being connected to a structure such as a hoist through a lifting component, thereby effectively preventing or slowing down pirates from reaching the cab.

[0046] In an embodiment, the height of the first position can be higher than the height of the second position 6. In the horizontal direction, the second position 6 can be staggered relative to the first position, so that the ladder body 4 whose two ends are respectively connected to the first position and the allowable position presents an inclined arrangement posture. The first direction mentioned in the above description is the extension direction of the ladder body 4 after the inclined arrangement.

[0047] In an embodiment, as an example, the first handrail assembly can be fixedly connected to the ladder body 4, such as by welding, and the second handrail assembly 2 can be detachably connected to the ladder body 4 and the first handrail assembly by a connecting member (such as an assembly formed by bolts and nuts), which will be specifically described in the subsequent description.

[0048] Furthermore, in the embodiment, the ladder body 4 may be a ladder-like structure, that is, having two longitudinal beams spaced apart, with a plurality of climbable rods or plate-like structures spaced apart in the first direction along the longitudinal beams.

[0049] In the embodiment, the lifting member 7 may be a plate-like structure, and the plate-like structure may have a through hole, and the through hole may be used for fixing an external lifting device. The external lifting device may be, for example, a hand chain hoist or an electric hoist, and a deck hoist eye 8 may be provided on the ship, and the inclined ladder may be lifted by passing a sling through the through hole of the plate-like structure and the deck hoist eye 8.

[0050] According to the inclined ladder provided by the embodiment of the present invention, the second handrail assembly 2 may include a plurality of first overlapping portions 5 extending along the second direction, and the aforementioned plurality of first overlapping portions 5 may be arranged at intervals along the first direction. The inclined ladder may also include a plurality of second overlapping portions extending along the second direction, and the aforementioned plurality of second overlapping portions are arranged one-to-one with the plurality of first overlapping portions 5, and each first overlapping portion 5 may be detachably connected to the corresponding second overlapping portion.

[0051] In an embodiment, each first overlapping portion 5 may be located on a side of the corresponding second overlapping portion away from the second end, each first overlapping portion 5 is detachably connected to the corresponding second overlapping portion, and the second direction is perpendicular to the first direction.

[0052] In an embodiment, according to the inclined ladder provided by an embodiment of the present invention, the second handrail assembly 2 and the first handrail assembly are detachably connected by overlapping as a whole, and each first overlapping portion 5 is located on the side of the corresponding second overlapping portion away from the second end. In other words, each first overlapping portion 5 is located on the upper side of the second overlapping portion, thereby allowing the second handrail assembly 2 to be laid down after disassembly.

[0053] Specifically, the second armrest assembly 2 can be tilted to the right in a clockwise direction with the position where the lowest first overlap portion 5 and the second overlap portion contact each other as a fulcrum. Since the remaining first overlap portions 5 are all located above their respective corresponding second overlap portions, during the tilting process, the remaining first overlap portions 5 and the corresponding second overlap portions will not further interfere with each other and hinder the tilting process.

[0054] The tipping of the second handrail assembly 2 mentioned in the above description is particularly beneficial when the crew completes the removal of the second handrail assembly 2 on the inclined ladder, and then pushes the second handrail assembly 2 to tip with the above fulcrum as the axis, so that the second handrail assembly 2 can quickly separate from the ladder body 4 and the first handrail assembly, creating favorable conditions for the lifting of the procedure. Therefore, the disassembly time of the second handrail assembly 2 can be saved, which is conducive to winning rescue time.

[0055] In the embodiment, as an example, the first overlap portion 5 and the second overlap portion can both be rod-shaped structures. The first overlap portion 5 can be a longitudinal rod in the second handrail assembly 2, and the longitudinal rod extends along the second direction. The second overlap portion can be, for example, a rod-shaped structure welded on the ladder body 4.

[0056] According to the inclined ladder provided by the embodiment of the present invention, the inclined ladder can also include a first connecting component arranged corresponding to each pair of first overlapping parts 5 and second overlapping parts connected to each other, and the first connecting component can be used to detachably connect each first overlapping part 5 to the corresponding second overlapping part.

[0057] In an embodiment, the first connecting component may include a first releasing member, which may be located on a side of the corresponding first lap joint 5 facing away from the second end, and the first releasing member may be configured to be removable from a side of the corresponding first lap joint 5 facing away from the second end to release the connection between the first lap joint 5 and the corresponding second lap joint.

[0058] In the embodiment, the first releasing member is located on the side of the corresponding first lap joint 5 facing away from the second end, which can be understood as the first releasing member is located on the side of the first lap joint 5 where the first end of the ladder body 4 is located, that is, on the upper side of the first releasing member, so that the crew can easily remove the first releasing member when moving upward along the inclined ladder, thereby releasing the connection between the first lap joint 5 and the second lap joint.

[0059] As an example, in an embodiment, as described above, the first connection assembly may be a combination of a first bolt and a first butterfly nut, that is, the first release member may be a first butterfly nut. In an embodiment, the first overlap portion 5 and the second overlap portion may respectively have through holes corresponding to each other, the first bolt penetrates the first overlap portion 5 and the second overlap portion, and then the first butterfly nut is screwed on the first bolt to connect the first overlap portion 5 and the second overlap portion to each other.

[0060] In the embodiment, the butterfly nut is used so that the crew can remove the butterfly nut by directly screwing it by hand, thereby reducing the removal time.

[0061] According to the inclined ladder provided in an embodiment of the present invention, the first handrail assembly may include a plurality of first handrail rods spaced apart along a second direction, the second handrail assembly 2 includes a plurality of second handrail rods 3 spaced apart along the second direction, and the plurality of first handrail rods are detachably connected to the plurality of second handrail rods 3 in a one-to-one correspondence.

[0062] In an embodiment, each first handrail bar may have a first step portion, and the corresponding second handrail bar 3 may have a second step portion, the first step portion and the second step portion are butted against each other, and the second direction may be perpendicular to the first direction.

[0063] In the embodiment, the corresponding first handrail rod and the second handrail rod 3 are butted against each other, so as to facilitate the positioning of the second handrail assembly 2 and the first handrail assembly when they are connected to each other. In the embodiment, the number of the first handrail rods can be, for example, two, and the number of the second handrail rods 3 can also be, for example, two.

[0064] According to the inclined ladder provided by an embodiment of the present invention, the first step portion of the first handrail bar farthest from the ladder body 4 among the multiple first handrail bars may include a first protruding structure, and the corresponding first step portion of the second handrail bar 3 may include a second protruding structure, the first protruding structure may be located on one side of the second protruding structure in the second direction, and the first protruding structure may be closer to the adjacent first handrail bar relative to the second protruding structure.

[0065] That is, in the embodiment, the first protruding structure can be located below the second protruding structure, so that when the second armrest assembly 2 is tilted in the manner described above, the first protruding structure will not interfere with the second protruding structure, resulting in the tilting process of the second armrest assembly 2 being affected. In addition, in the embodiment, both the first protruding structure and the second protruding structure can be rectangular parallelepiped structures.

[0066] According to the inclined ladder provided by the embodiment of the present invention, the inclined ladder may further include a second connection assembly, and the second connection assembly may detachably connect the first protruding structure and the second protruding structure. In an embodiment, the second connection assembly may include a second release member, and the second release member may be located on a side of the first protruding structure facing away from the second protruding structure, and the second release member may be configured to be removable from a side of the first protruding structure facing away from the second protruding structure to release the connection between the first protruding structure and the second protruding structure.

[0067] In the embodiment, the structure of the second connection assembly can be the same as that of the first connection assembly, that is, the second bolt and the second butterfly nut. In the embodiment, as mentioned in the above description, the second butterfly nut is substantially located on the lower side of the first protruding structure, which makes the upper side of the uppermost handrail formed by the uppermost first handrail rod and the second handrail rod 3 connected to each other smooth and does not affect the gripping and use of the person.

[0068] According to the inclined ladder provided in an embodiment of the present invention, among the first handrails farthest from the ladder body 4 among the multiple first handrails, each first handrail can have a third protruding structure, and the corresponding second handrail 3 has a fourth protruding structure.

[0069] In an embodiment, the inclined ladder may further include a third connecting assembly, which may detachably connect the third protruding structure and the fourth protruding structure along a third direction, and the third direction may be perpendicular to the first direction and the second direction.

[0070] In an embodiment, the third connection assembly includes a third release member, the third release member is located outside the third protruding structure and the fourth protruding structure connected to each other, and the third release member is configured to be removable from the outside of the third protruding structure and the fourth protruding structure to release the connection between the first protruding structure and the second protruding structure.
