[0030] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection, an electrical connection, or a communication connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly limited. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The technical solution of the present utility model is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0031] like Figures 3 to 5 As shown, the movable inclined ladder used for the maintenance space inside the ship in this embodiment includes: a vertical guide rail 4, a horizontal guide rail 5, a first limited rotation mechanism, a second limited rotation mechanism, a turning platform 6 and an inclined ladder 7.

[0032] The vertical guide rail 4 is fixed on the bulkhead 8 by welding or bolts.

[0033] One end of the horizontal guide rail 5 ( Figure 4 The left end in the middle) is rotatably arranged at the lower end of the vertical guide rail 4 through a first position-limiting rotation mechanism. The first position-limiting rotation mechanism is located at Figure 4 and Figure 5 The first limit rotation mechanism is used to keep the horizontal guide rail 5 in a horizontal state and not continue to rotate downward when the horizontal guide rail 5 rotates to a horizontal state. A possible first limit rotation mechanism is: a horizontal limit plate is set at the lower end of the vertical guide rail 4, and the horizontal limit plate is fixed to the lower end of the vertical guide rail 4 by welding or screws and kept in a horizontal setting, and the lower end of the vertical guide rail 4 is aligned with the left end of the horizontal guide rail 5 ( Figure 4 ) is rotatably connected through a rotating shaft, and the horizontal guide rail 5 is abutted against the horizontal limit plate when it is rotated to the horizontal position, so that the horizontal guide rail 5 no longer continues to rotate downward.

[0034] A possible structure of the horizontal guide rail 5 is: it is composed of two guide rails fixedly arranged at a certain distance, and the left ends ( Figure 4 ) is rotatably arranged at the lower end of the vertical guide rail 4 through a mechanical structure of a rotating shaft-rotating hole.

[0035] The other end of the horizontal guide rail 5 ( Figure 4 The upper end of the inclined ladder 7 (right end in the middle) is rotatably arranged through a second limited rotation mechanism. Figure 4A possible second position-limiting rotation mechanism is as follows: a rotation shaft is provided on the inclined ladder 7, a rotation through hole is provided at the right end of the horizontal guide rail 5, and the inclined ladder 7 is rotatably connected to the horizontal guide rail 5 via the rotation shaft and the rotation through hole.

[0036] The flip platform 6 is arranged on the horizontal guide rail 5. The user climbs onto the flip platform 6 via the inclined ladder 7, and then reaches the second floor to maintain the equipment on the second floor. A possible solution is that the flip platform 6 is arranged in two guide rails of the horizontal guide rail 5. For example, two layers of sliding grooves (the openings of the grooves are arranged horizontally) are arranged in each guide rail of the horizontal guide rail 5, the upper sliding groove is used to fix the flip platform 6, and the lower sliding groove is used to provide a slideway for the inclined ladder 7. Two sliding ends (such as spherical ends) can be arranged on both sides of the upper end of the inclined ladder 7, and the sliding ends are respectively stuck in the lower sliding groove for sliding. The structure of the vertical guide rail 4 is similar to that of the horizontal guide rail 5, that is, sliding grooves are arranged on both sides of the vertical guide rail 4, and the sliding grooves of the vertical guide rail 4 and the sliding grooves of the horizontal guide rail 5 are kept in communication, so that the inclined ladder 7 can slide along the sliding grooves of the vertical guide rail 4 and the horizontal guide rail 5 without obstacles.

[0037] A first locking mechanism (such as a movable latch fixed on the ship's deck, which is a prior art) is provided at the lower end of the inclined ladder 7, and the lower end of the inclined ladder 7 can be slidably held against the ground (i.e., the deck), so that the inclined ladder 7 slides to the first locking mechanism, and the lower end of the inclined ladder 7 is fixed by the first locking mechanism to prevent sliding, so that the inclined ladder 7 and the horizontal guide rail 5 are kept Figure 4 In the state shown, the user can climb onto the flip platform 6 along the inclined ladder 7 and then onto the second floor.

[0038] The method for unfolding the movable inclined ladder for maintaining the space inside the ship is as follows: pull the inclined ladder 7 to the right ( Figure 4 ), under the action of gravity and tension, the lower end of the horizontal guide rail 5 (assuming it is in a non-horizontal state before) rotates with the lower end of the vertical guide rail 4; when the horizontal guide rail 5 rotates to a horizontal state, the horizontal guide rail 5 is kept in a horizontal state by the first limit rotation mechanism and no longer rotates downward; the inclined ladder 7 is continued to be pulled, and the upper end of the inclined ladder 7 slides along the vertical guide rail 4 and keeps relative to the horizontal guide rail 5, and moves to the right end of the horizontal guide rail 5 ( Figure 4 ); Continue to drag the inclined ladder 7 to the right, and the inclined ladder 7 and the horizontal guide rail 5 are in a preset position (ie Figure 4 After the inclined ladder 7 is in the state shown in the figure, the lower end of the inclined ladder 7 can be fixed by the first locking mechanism for use by the user.

[0039] The storage method of the movable inclined ladder for the maintenance space inside the ship is as follows: unlock the first locking mechanism, move the inclined ladder 7 to the left along the horizontal guide rail 5 (specifically the sliding groove) to the vertical guide rail 4 (specifically the sliding groove), continue to move upward along the vertical guide rail 4 (specifically the sliding groove), and finally to the vertical guide rail 4 (specifically the sliding groove). Figure 5 Position shown; when moving to Figure 5 After reaching the position, the horizontal guide rail 5 and the flip platform 6 can continue to rotate along the position marked by I in the figure until the horizontal guide rail 5 and the vertical guide rail 4 approximately overlap.

[0040] By adopting this technical solution, a foldable inclined ladder can be provided for users to use, which is safer and more comfortable than a straight ladder. It can be stored when not in use, occupying less space, thereby increasing the effective use space of the ship and thus improving its economy.

[0041] In a feasible solution, it also includes: a handrail 12, which is arranged at the upper end of the vertical guide rail for customers to support and improve safety.

[0042] In a feasible solution, a first limiting mechanism 9 is further provided at the upper end of the handrail 12. A possible limiting mechanism 9 is: an inverted U-shaped structure is provided at the upper end of the handrail 12, and when the upper end of the inclined ladder 7 moves to the top end of the vertical guide rail 4, it abuts against the first limiting mechanism 9 to prevent the inclined ladder 7 from continuing to ascend.

[0043] This technical solution is adopted to avoid misoperation, which may cause the inclined ladder 7 to disengage from the vertical track 4.

[0044] In a feasible solution, the turning platform 6 is a grid structure.

[0045] This technical solution is adopted to reduce the weight of the movable inclined ladder and facilitate operation.

[0046] In a feasible solution, the turning platform 6 is detachably connected to the horizontal guide rail 5. As mentioned above, the turning platform 6 can be removed from the horizontal guide rail 5, and a turning platform 6 of different structures can be replaced according to different loads.

[0047] In a feasible solution, a handrail 10 is further provided on the inclined ladder 7. The handrail 10 is arranged on both sides of the inclined ladder 7 to provide protection for the user.

[0048] In a feasible solution, the handrail 10 is connected to the inclined ladder 7 in a flippable manner, that is, in the stowed state, the handrail 10 can be flipped to be parallel to the bulkhead 8 to further reduce space occupancy.

[0049] In a feasible solution, a second locking mechanism is further provided at the portion where the horizontal guide rail 5 is connected to the inclined ladder 7. A possible second locking mechanism may be: positioning holes are provided on the horizontal guide rail 5 and the inclined ladder 7, and a positioning rod is inserted into the positioning hole to fix the horizontal guide rail 5 and the inclined ladder 7.

[0050] This technical solution is adopted in order to enable the inclined ladder 7 to be fixed at a preset position of the horizontal guide rail 5 .

[0051] In a feasible solution, it further includes: a third locking mechanism, which is arranged directly below the vertical guide rail and is used to fix the inclined ladder 7 in the stored state. A possible third locking mechanism is: a rotatable lever is arranged on the bottom surface directly below the vertical guide rail, and when the inclined ladder 7 is stored to the Figure 5 After the lever is moved to the position shown in the figure, the lever is rotated to the position where the inclined ladder 7 is located, and the lever is abutted against the inclined ladder 7 to prevent the inclined ladder 7 from shaking.

[0052] In a feasible solution, a roller 11 is provided at the lower end of the inclined ladder 7 .

[0053] The rollers 11 are added to facilitate the use and storage of the inclined ladder 7 and reduce the friction between the inclined ladder 7 and the ground.

[0055] Moreover, the first feature being “above”, “above”, and “above” the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being “below”, “below”, and “below” the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
