Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a ship inclined ladder and its installation method. Background Technology

[0002] In the shipbuilding industry, outdoor ramps are typically used to connect multiple ship sections to provide access for personnel. In traditional installation methods, the four feet of the ramp are located in two different sections (e.g., the upper foot is in the upper section and the lower foot is in the lower section), so the ramp usually needs to be installed normally at the overall section stage.

[0003] However, this installation method has significant problems: First, during the overall section installation, the hoisting space for some inclined ladders is limited due to the multiple decks above, making hoisting difficult. Second, the installation process inevitably damages the paint already applied to the sections, requiring repainting and increasing workload and costs. Furthermore, if inclined ladders are installed in sections, the lack of stable landing points at the bottom necessitates the use of temporary steel reinforcement, but removing these temporary supports later will also damage the section's paint, increasing construction complexity and safety risks. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defect of the prior art that the paint is easily damaged when building an outdoor inclined ladder during normal installation in the section stage, and to provide a ship inclined ladder and its installation method.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A ship's inclined ladder includes an inclined ladder body for connecting at least two ship sections;

[0007] The ship's inclined ladder also includes a first connecting structure, which is used to connect the ship's layered sections to the upper ladder foot near the main body of the inclined ladder.

[0008] The inclined ladder body is detachably connected to the first connecting structure, and the angle between the inclined ladder body and the ship's layered sections is adjustable and can be fixed.

[0009] In this technical solution, by providing the ship's inclined ladder, it is convenient to install the main body of the inclined ladder when the ship's layers and sections are in an inverted state, and then adjust and fix the main body of the inclined ladder when the ship's layers and sections are in a normal state. In this way, the first connecting structure provides a suitable fixing point for the main body of the inclined ladder, and makes the angle between the main body of the inclined ladder and the ship's layers and sections adjustable. After adjustment, the lower ladder foot of the main body of the inclined ladder can land on the ground and obtain a stable landing point. Then the angle is fixed to avoid damaging the paint that has been completed on the ship's layers and sections.

[0010] Preferably, the ship's inclined ladder further includes a second connecting structure, one side of which is connected to the main body of the inclined ladder, and the other side of which is detachably, adjustable, and fixedly connected to the first connecting structure.

[0011] In this technical solution, the above-mentioned settings facilitate maintaining the integrity of the surface of the inclined ladder body during installation and adjustment, concentrate potential wear and damage at the connection points on the separately replaceable second connection structure, and also facilitate the manufacturing of the connection points, thereby improving pre-outfitting efficiency and construction convenience.

[0012] Preferably, the first connecting structure is provided with a first connecting channel, and the second connecting structure is provided with a second connecting channel;

[0013] The ship's inclined ladder also includes a connector, which passes through the first connecting channel and the second connecting channel to connect the first connecting structure and the second connecting structure.

[0014] In this technical solution, through the above-mentioned settings, the other side of the second connecting structure can be detachably, adjustablely, and fixedly connected to the first connecting structure in a relatively simple structure. The efficiency of connection and disassembly is improved by whether or not the connecting parts are inserted. The hole design allows the connecting parts to move within a certain range, thereby achieving fine adjustment of position and angle.

[0015] Preferably, the first connecting channel and / or the second connecting channel are oblong holes; and / or,

[0016] The first connecting structure is provided with at least two symmetrically arranged first connecting channels, and the second connecting structure is provided with at least two symmetrically arranged second connecting channels.

[0017] In this technical solution, by setting the first connecting channel and / or the second connecting channel as an oblong hole, the connector is allowed to move linearly along the length of the oblong hole to both ends of the oblong hole, which facilitates the adjustment of the angle of the inclined ladder body and the layered sections of the ship by adjusting the connector.

[0018] By having at least two symmetrically arranged first connecting channels on the first connecting structure and at least two symmetrically arranged second connecting channels on the second connecting structure, the connecting force is evenly distributed. This also helps the first and second connecting structures to work together to prevent the inclined ladder body from swaying or tilting unnecessarily after being fixed, thus improving the stability and safety of the inclined ladder body.

[0019] Preferably, the first connecting structure includes a first support portion that protrudes from the side surface of the first connecting structure near the ship's layered sections.

[0020] In this technical solution, the contact area between the surface of the first connecting structure near the ship's layered sections and the ship's layered sections is reduced by the above-mentioned arrangement. This reduces the impact of the minute displacement of the first connecting structure under friction or shear force on the surface of the ship's layered sections, and further avoids damage to the paint that has already been applied to the ship's layered sections.

[0021] Preferably, the second connecting structure includes a second support portion that protrudes from one side surface of the second connecting structure near the inclined ladder body.

[0022] In this technical solution, the contact area between the surface of the second connecting structure closest to the inclined ladder body and the inclined ladder body is reduced by the above-mentioned arrangement. This reduces the impact of the slight displacement of the second connecting structure under friction or shear force on the surface of the inclined ladder body, further avoids the impact of vibration and wear on the inclined ladder body, and extends the service life of the inclined ladder body.

[0023] Preferably, the projection of the second connecting structure can completely cover the first connecting structure along a direction perpendicular to the side surface of the first connecting structure that is closer to the second connecting structure.

[0024] In this technical solution, the above settings ensure full contact and uniform load distribution between the first and second connecting structures during angle adjustment, thereby improving the reliability and stability of the connection and reducing the degree of limitation on the adjustment angle caused by the partial mismatch between the first and second connecting structures.

[0025] Preferably, when the inclined ladder body is connected to the first connecting structure, the distance between the first connecting structure and the anti-top beam of the ship's layered section near the upper ladder foot of the inclined ladder body is 1600mm-1800mm along the height direction of the ship's layered sections.

[0026] In this technical solution, the above settings optimize the construction space, making it easier for a single construction worker to connect the first connecting structure to the ship in layers and sections while standing on the ground during the reaction phase, without the need for excessive height adjustment tools.

[0027] A method for installing a ship's inclined ladder, used for installing a ship's inclined ladder as described above;

[0028] The ship's inclined ladder connects the first ship layer section and the second ship section. In the normal ship section, the first ship layer section is located below the second ship layer section.

[0029] The steps of the ship inclined ladder installation method include:

[0030] S1. Under the reverse state, manufacture the second ship in layers and sections;

[0031] S2. Connect the first connecting structure to the second ship layer section and paint the second ship layer section;

[0032] S3. Connect the main body of the inclined ladder to the first connecting structure;

[0033] S4. Convert the second ship's layered sections into a normal state and install them on the normalized first ship's layered sections to form the ship's overall section;

[0034] S5. Adjust the angle between the first connecting structure and the inclined ladder body until the upper and lower steps of the inclined ladder body are in preset positions, and then fix the inclined ladder body on the first connecting structure.

[0035] In this technical solution, by providing the ship inclined ladder installation method, it is possible to manufacture the second ship in layers and sections, install the connecting structure and the main body of the inclined ladder in the reverse state, and then adjust the angle of the main body of the inclined ladder in the normal state. This reduces paint damage and the use of temporary tooling, improves production efficiency, and reduces costs and construction difficulty.

[0036] Preferably, the ship's inclined ladder further includes a second connecting structure, one side of which is connected to the main body of the inclined ladder, and the other side of which is detachably, adjustable, and fixedly connected to the first connecting structure;

[0037] S3 also includes;

[0038] S31. Connect the second connecting structure to the inclined ladder body, and then connect the second connecting structure to the first connecting structure.

[0039] In this technical solution, the above-mentioned settings facilitate maintaining the integrity of the surface of the inclined ladder body during installation and adjustment, concentrate potential wear and damage at the connection points on the separately replaceable second connection structure, and also facilitate the manufacturing of the connection points, thereby improving pre-outfitting efficiency and construction convenience.

[0040] The positive and progressive effects of this invention are as follows:

[0041] By providing this ship's inclined ladder, it is convenient to install the main body of the inclined ladder when the ship's layers and sections are in an inverted state, and then adjust and fix the main body of the inclined ladder when the ship's layers and sections are in a normal state. In this way, the first connecting structure provides a suitable fixing point for the main body of the inclined ladder, and makes the angle between the main body of the inclined ladder and the ship's layers and sections adjustable. After adjustment, the lower ladder foot of the main body of the inclined ladder can land on the ground and obtain a stable landing point. Then the angle is fixed to avoid damaging the paint that has been completed on the ship's layers and sections.

[0042] By providing this method for installing the ship's inclined ladder, it is possible to manufacture the second ship in a reverse state by layering and sectioning, installing the connecting structure and the main body of the inclined ladder, and then adjusting the angle of the main body of the inclined ladder in a normal state. This reduces paint damage and the use of temporary tooling, improves production efficiency, and reduces costs and construction difficulty. Attached Figure Description

[0067] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0068] like Figures 1-6 As shown, this embodiment provides a ship inclined ladder 1, which includes an inclined ladder body 11, which is used to connect at least two ship sections.

[0069] The ship's inclined ladder 1 also includes a first connecting structure 12, which is used to connect with the ship's layered section (in this embodiment, the second ship layered section 22) near the upper ladder foot 111 of the inclined ladder body 11.

[0070] The inclined ladder body 11 is detachably connected to the first connecting structure 12, and the angle between the inclined ladder body 11 and the ship's layered sections is adjustable and can be fixed.

[0071] The above configuration facilitates the installation of the inclined ladder body 11 when the ship's layered sections are in an inverted state, and the adjustment and fixation of the inclined ladder body 11 when the ship's layered sections are in a normal state. In this way, the first connecting structure 12 provides a suitable fixing point for the inclined ladder body 11, and makes the angle between the inclined ladder body 11 and the ship's layered sections adjustable. After adjustment, the lower ladder foot 112 of the inclined ladder body 11 can land on the ground and obtain a stable landing point. Then the angle is fixed to avoid damaging the paint that has been completed on the ship's layered sections.

[0072] In this embodiment, the ship's inclined ladder 1 also includes a second connecting structure 13. One side of the second connecting structure 13 is connected to the main body 11 of the inclined ladder, and the other side of the second connecting structure 13 is detachably, adjustable, and fixedly connected to the first connecting structure 12. This facilitates maintaining the integrity of the surface of the main body 11 of the inclined ladder during installation and adjustment, concentrates possible wear and damage at the connection point on the separately replaceable second connecting structure 13, and also facilitates the manufacturing of the connection point, improving pre-outfitting efficiency and construction convenience.

[0073] In this embodiment, the first connecting structure 12 is provided with a first connecting channel 122, and the second connecting structure 13 is provided with a second connecting channel 132. The ship's inclined ladder 1 also includes a connector 15, which passes through the first connecting channel 122 and the second connecting channel 132 to connect the first connecting structure 12 and the second connecting structure 13. This relatively simple structure allows the other side of the second connecting structure 13 to be detachably, adjustablely, and fixedly connected to the first connecting structure 12. The efficiency of connection and disassembly is improved by whether or not the connector 15 is inserted. The channel design allows the connector 15 to move within a certain range, thereby achieving fine adjustment of position and angle.

[0074] In this embodiment, the connector 15 is an M16 bolt with a nut; in other embodiments, the connector 15 may also be a fastener of other forms and sizes, such as a screw with a double nut, a pin with a locking ring, etc.

[0075] In this embodiment, the second connecting channel 132 is an oblong hole, which allows the connector 15 to move linearly along the length direction X of the oblong hole to both ends of the oblong hole, so as to facilitate the angle adjustment of the inclined ladder body 11 and the ship's layered sections by adjusting the connector 15.

[0076] In this embodiment, the first connecting channel 122 is a round hole adapted to the connector 15 so as to stably connect with the connector 15 and allow the first connector 15 to be rotated on the second connector 15 for adjustment; in other embodiments, the first connecting channel 122 may also be set as an oblong hole to allow linear movement of the connector 15.

[0077] In this embodiment, the first connecting structure 12 is provided with at least two symmetrically arranged first connecting channels 122, and the second connecting structure 13 is provided with at least two symmetrically arranged second connecting channels 132, so that the connecting force is evenly distributed, and the first connecting structure 12 and the second connecting structure 13 together prevent the inclined ladder body 11 from shaking or tilting unnecessarily after being fixed, thereby improving the stability and safety of the inclined ladder body 11.

[0078] In this embodiment, by moving the bolt in the opposite direction of the length X of the two waist-shaped holes, the angle between the inclined ladder body 11 and the ship's layered sections can be easily adjusted; by tightening the nut on the bolt, the inclined ladder body 11 can be fixed on the ship's layered sections; after separating the nut and the bolt, the inclined ladder body 11 can be removed from the ship's layered sections.

[0079] In this embodiment, the first connecting structure 12 includes a first support portion 121, which protrudes from the side surface of the first connecting structure 12 near the ship's layered section. This reduces the contact area between the side surface of the first connecting structure 12 near the ship's layered section and the ship's layered section, thereby reducing the impact of the slight displacement of the first connecting structure 12 under friction or shear force on the surface of the ship's layered section and further avoiding damage to the already finished paint on the ship's layered section.

[0080] In this embodiment, the first support portion 121 of the first connecting structure 12 is connected to the ship's layered sections via the third connecting structure 14, and the third connecting structure 14 is welded to the ship's layered sections. In other embodiments, the first connecting structure 12 can also be connected to the ship's layered sections by any method that meets strength requirements, such as direct welding, hanging, or gluing.

[0081] In this embodiment, the second connecting structure 13 includes a second support portion 131, which protrudes from the side surface of the second connecting structure 13 near the inclined ladder body 11. This reduces the contact area between the side surface of the second connecting structure 13 near the inclined ladder body 11 and the inclined ladder body 11, thereby reducing the impact of the small displacement of the second connecting structure under friction or shear force on the surface of the inclined ladder body 11. This further avoids the impact of vibration and wear on the inclined ladder body 11 and extends the service life of the inclined ladder body 11.

[0082] In this embodiment, along the direction Y perpendicular to the side surface of the first connecting structure 12 closest to the second connecting structure 13, the projection of the second connecting structure 13 can completely cover the first connecting structure 12, ensuring sufficient contact and uniform load distribution between the first connecting structure 12 and the second connecting structure 13 during angle adjustment, improving the reliability and stability of the connection, and reducing the degree of limitation on the adjustment angle caused by the inability of the first connecting structure 12 and the second connecting structure 13 to correspond locally.

[0083] In this embodiment, along the direction Y perpendicular to the side surface of the first connecting structure 12 and close to the second connecting structure 13, the projected shapes and positions of the first support portion 121 and the second support portion 131 correspond to each other, so that the stress concentration positions correspond and the lifespan of the first connecting structure 12 and the second connecting structure 13 is improved.

[0084] In this embodiment, the first support 121 and the second support 131 are both cut from channel steel, and the main body of the first connecting structure 12 and the second connecting structure 13 are cut from steel plate to facilitate manufacturing; in other embodiments, the first connecting structure and the second connecting structure can be made of other profiles or materials, such as I-beams, aluminum, etc.

[0085] In this embodiment, when the inclined ladder body 11 is connected to the first connecting structure 12, the distance D between the first connecting structure 12 and the anti-top beam 221 of the ship's layered sections near the upper ladder foot 111 of the inclined ladder body 11 is 1750mm. This optimizes the construction space, allowing a single construction worker to connect the first connecting structure 12 to the ship's layered sections from the ground during the inversion phase, without requiring excessive height adjustment tools. In other embodiments, the distance between the first connecting structure 12 and the anti-top beam 221 of the ship's layered sections near the upper ladder foot 111 of the inclined ladder body 11 can also be other values ​​within the range of 1600mm-1800mm to achieve a similar effect.

[0086] like Figure 7 As shown, this embodiment also provides a method for installing a ship inclined ladder 1, used for installing the ship inclined ladder 1 as described above; the ship inclined ladder 1 connects the first ship layer section 21 and the second ship section, and in the normal ship section 2, the first ship layer section 21 is located below the second ship layer section 22; the steps of the ship inclined ladder 1 installation method include:

[0087] S1. Under the inverse state, manufacture the second ship layered section 22;

[0088] S2. Connect the first connecting structure 12 to the second ship layer section 22 and paint the second ship layer section 22.

[0089] S3. Connect the main body 11 of the inclined ladder to the first connecting structure 12;

[0090] S4. Convert the second ship layer section 22 into a normal state and install it on the normal first ship layer section 21 to form the ship section 2;

[0091] S5. Adjust the angle between the first connecting structure 12 and the inclined ladder body 11 until the upper ladder foot 111 and the lower ladder foot 112 of the inclined ladder body 11 are in the preset position, and then fix the inclined ladder body 11 on the first connecting structure 12.

[0092] This allows for the inverse state manufacturing of the second ship in layers and sections 22, installation of connecting structures and inclined ladder main body 11, and then adjustment of the angle of inclined ladder main body 11 in the normal state. This reduces paint damage and the use of temporary tooling, improves production efficiency, and reduces costs and construction difficulty.

[0093] In this embodiment, the ship's inclined ladder 1 further includes a second connecting structure 13, one side of which is connected to the main body 11 of the inclined ladder, and the other side of which is detachably, adjustable, and fixedly connected to the first connecting structure 12; S3 also includes;

[0094] S31. Connect the second connecting structure 13 to the inclined ladder body 11, and then connect the second connecting structure 13 to the first connecting structure 12.

[0095] This facilitates maintaining the integrity of the surface of the inclined ladder body 11 during installation and adjustment, concentrates potential wear and damage at the connection point on the separately replaceable second connection structure 13, and also facilitates the manufacturing of the connection point, improving pre-outfitting efficiency and construction convenience.
