Description

Technical Field

[0001] The utility model relates to a safety railing door, in particular to a translational ship railing door used on ships. Background Art

[0002] Ship railings are a key element in ensuring crew safety. They not only enhance the overall safety of the vessel but also effectively reduce accidents caused by falls or falling objects. In emergency situations, such as fire or collision, railing doors installed in the railings can serve as escape and rescue routes, thereby increasing the crew's chances of survival.

[0003] At present, the railing door design on the main deck of the ship usually adopts a hinged structure, such as Figure 1 As shown, the railing door is hinged to the railing via a hinged structure, allowing it to rotate relative to the railing. This design is used in areas of the side railing that facilitate inbound and outbound traffic, replacing fixed railings. When closed, this railing door provides the same protection as a fixed railing; when open, it facilitates boarding and material handling. However, hinged railing doors require a 180° semicircular motion to open and close, which occupies a significant amount of inboard space, making them difficult to operate and impacting the deck layout. Utility Model Content

[0004] The utility model provides a translational ship railing door which has a simple structure, does not occupy space and is convenient to use on ships with narrow space such as container ships.

[0005] The translational marine railing door described in the utility model includes two relatively vertically arranged first railing posts and second railing posts, and a movable door frame movably installed on the first railing post and moving back and forth between the first railing post and the second railing post. The movable door frame includes a plurality of sliding rods passing through the first railing post and vertical rods connecting the sliding rods. The first railing post is provided with a through hole for the sliding rod to pass through.

[0006] Furthermore, the vertical rod is connected to one end of each sliding rod and is located between the first railing column and the second railing column, and the other end of the sliding rod is provided with a limiting plate.

[0007] Furthermore, the sliding rod is round steel.

[0008] Furthermore, a pad is provided in the through hole, and the sliding rod is in sliding contact with the pad.

[0009] Furthermore, opposite baffles with drilled holes are provided on both sides of the vertical rod, and the second railing column is provided with a fixed eye plate with drilled holes that matches the baffles.

[0010] The described translational marine railing door makes full use of the original railing posts on the ship's side as the first railing posts and the second railing posts, and a movable door frame is installed on the first railing post. The sliding rod of the movable door frame moves relatively in the through hole of the first railing post, and the railing door is closed and opened in a translational manner, thereby reducing the influence of the ship's space on the arrangement of the railing door; at the same time, the influence of the opening and closing of the railing door on the ship's space is also reduced. The translational marine railing door does not occupy space and is convenient for use on ships with limited space such as container ships, making the arrangement of the railing door more reasonable.

[0017] The following will be combined with the accompanying drawings 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.

[0018] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0019] If there are descriptions involving "first" or "second" in the embodiments of the present invention, the descriptions of "first" or "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0020] like Figure 2-6 As shown, a translational marine railing door comprises two relatively vertically arranged first and second railing posts 1 and 2, and a movable door frame 3 movably mounted on the first railing post for movement back and forth between the first and second railing posts. The movable door frame comprises a plurality of sliding rods 301 extending through the first railing posts and a vertical rod 302 connecting the sliding rods. The first railing posts are provided with through holes 101 for the sliding rods to pass through. The invention utilizes the existing railing posts on the ship's side as the first and second railing posts, and mounts a movable door frame on the first railing post. The sliding rods of the movable door frame move relative to each other within the through holes of the first railing post. The railing door is closed and opened by translation, reducing the impact of the ship's interior space on the railing door layout. This also reduces the impact of the railing door opening and closing on the ship's interior space. The translational marine railing door does not occupy space and is convenient for use on ships with limited space, such as container ships, making the railing door layout more reasonable.

[0021] The vertical rod 302 is connected to one end of each sliding rod 301 and is located between the first railing column and the second railing column. The other end of the sliding rod 301 is provided with a limit plate 303. The sliding rods are connected as a whole through the vertical rod, driving the sliding rod relative to the first railing column, so that each sliding rod spans between the first railing column and the second railing column to play a guardrail role. At the same time, a limit plate is provided at the other end to prevent the sliding rod from sliding too much and sliding out of the first railing column, and its vertical rod on the other side of the first railing column can also play a role of limiting to prevent the sliding rod from sliding out of the first railing column.

[0022] The sliding rod 301 is made of round steel and can slide relative to the first railing post.

[0023] A gasket 102 is provided in the through hole 101, and the sliding rod is in sliding contact with the gasket, which is made of Teflon. When the sliding rod slides in the through hole, it contacts the Teflon gasket instead of directly contacting the first railing column, which can prevent the sliding rod from rubbing in the through hole to generate noise and sparks.

[0024] Opposite baffles 304 with drilled holes are provided on either side of the vertical bar 302, and a fixed eyelet 201 with drilled holes that cooperates with the baffles is provided on the second railing post 2. Furthermore, two pairs of baffles can be provided, vertically arranged on either side of the vertical bar. When the movable door frame is translated to a closed position aligned with the second railing post, a fixing pin 4 or a fixed lock is used to secure the movable door frame to the second railing post. When the movable door frame is fully opened, a stopper chain 5 with a pin is passed through the drilled holes of the two baffles and is looped over the first railing post, securing the railing door in its open position, i.e., the first railing post. This prevents the movable door frame from freely moving and potentially injuring crew members.

[0025] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
