Description

Technical Field

[0001] This utility model relates to the field of ship gangway technology, specifically a combined gangway structure for large ships. Background Technology

[0002] A gangway is a passageway between a ship and the outside world. Passenger ships should be equipped with gangways, as should other large and medium-sized ships. Small ships generally do not have gangways. Gangways are usually located at the edge of the lowest deck passageway on both sides of the ship that is not enclosed by the hull plating. Depending on the size of the ship and the needs of use, usually one gangway is installed on each side. The gangways used on medical ships for maritime rescue need to connect to ships of different sizes.

[0003] However, most traditional marine gangways are pre-assembled and installed on the side of the hull using lifting equipment. They are then lowered when needed, making the process cumbersome, requiring large equipment, increasing the risk of accidents during operation, necessitating long-term maintenance, and occupying significant space after being raised. Therefore, modular retractable gangways have emerged on the market. However, existing modular retractable gangway structures suffer from limitations in their ladder structure, resulting in poor retraction and expansion efficiency, and the equipment remains bulky and inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to provide a combined gangway structure for large ships to solve the problems raised in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

A base is hinged to the bottom end of the support plate, and a hydraulic telescopic rod is fixedly mounted at the bottom end of the gangway plate. The telescopic end of the hydraulic telescopic rod is fixedly connected to a support plate at the bottom end of the telescopic gangway plate. Guide support columns are fixedly mounted on both sides of the end of the gangway plate away from the support plate, and guide rings are fixedly mounted on both sides of the bottom end of the telescopic gangway plate. The guide rings are slidably connected to the guide support columns.

[0007] In a preferred embodiment, the retractable escalator includes a gangway board and a retractable escalator board with a retractable slot at the upper end. The retractable slot has a plurality of mounting seats evenly spaced inside. Each mounting seat has a support column rotatably mounted on it. The upper ends of the plurality of support columns are all located at the lower end of the same handrail. The handrail can be retracted into the retractable slot, which can prevent the handrail from affecting the retraction of the retractable escalator board.

[0008] In a preferred embodiment, an adjusting column is slidably disposed on the support column, the adjusting column is rotatably disposed at the bottom end of the handrail, and a locking bolt is disposed on the upper side wall of the support column.

[0009] In a preferred embodiment, a limiting hole is provided on the outer side wall of the bottom end of the support column, a limiting post is provided on one side of the limiting hole, and a movable plate is fixedly connected to one end of the limiting post. The movable plate is provided at the outer end of the gangway board and the telescopic ladder board, and a pull ring is provided at the outer end of the movable plate. The support column can be limited and fixed by inserting the limiting post into the limiting hole, and the movable plate can be easily pulled by using the pull ring.

[0010] In a preferred embodiment, a spring is provided on the inner side of the movable plate. The spring is embedded in the outer wall of the gangway plate and the telescopic ladder plate. The spring allows the limiting post to be tightly inserted into the limiting hole and also facilitates the adjustment of the handrail.

[0011] In a preferred embodiment, limit grooves are provided on the side walls at both ends of the gangway plate, and limit sliders are provided on both sides of the bottom end of the telescopic gangway plate. The limit sliders are slidably disposed in the limit grooves, and the limit sliders are integrally formed with the telescopic gangway plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, by incorporating a hydraulic telescopic rod, telescopic ladder plate, support plate, guide support column, guide ring, limiting groove, and limiting slider, enables the overlapping telescopic ladder plate and gangway plate to extend and retract. The guide support column, limiting groove, limiting slider, and hydraulic telescopic rod support the telescopic ladder plate, resulting in better structural stability and extension / retraction performance. This leads to a smaller footprint for ship gangways, making them more convenient to use.

[0014] 2. This utility model, by setting up a storage groove, mounting base, support column, adjustment column, limiting hole, limiting post, handrail, moving plate, spring and other structures, allows the handrail to be stored in the storage groove when the telescopic ladder needs to be extended and folded, and the handrail to be erected when the ladder needs to be used, and the limiting post and limiting hole are used to limit and fix the handrail, which can prevent the handrail from affecting the extension and retraction effect when the telescopic ladder is extended and retracted.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Please refer to Figures 1-4 This utility model provides a combined gangway structure for large ships, the technical solution of which is as follows:

[0022] A modular gangway structure for large ships includes a support plate 1, a gangway plate 2 fixedly mounted at one end of the support plate 1, a telescopic gangway plate 3 slidably mounted at the end of the gangway plate 2 away from the support plate 1, and storage ladders 4 on both sides of the upper end of the telescopic gangway plate 3 and the gangway plate 2. A base 5 is hinged to the bottom end of the support plate 1, a hydraulic telescopic rod 6 is fixedly mounted at the bottom end of the gangway plate 2, the telescopic end of the hydraulic telescopic rod 6 is fixedly connected to a support plate 7 at the bottom end of the telescopic gangway plate 3, guide support columns 8 are fixedly mounted on both sides of the end of the gangway plate 2 away from the support plate 1, and guide rings 9 are fixedly mounted on both sides of the bottom end of the telescopic gangway plate 3. The guide rings 9 are slidably connected to the guide support columns 8.

[0023] In a preferred embodiment, the storage ladder 4 includes storage slots 401 formed at the upper ends of the gangway 2 and the telescopic ladder 3. A plurality of mounting seats 402 are evenly spaced inside the storage slot 401. Each mounting seat 402 is rotatably mounted with a support column 403, and the upper ends of the multiple support columns 403 are all located at the lower end of the same handrail 404. An adjusting column 405 is slidably mounted on the support column 403, and the adjusting column 405 is rotatably mounted at the bottom end of the handrail 404. A locking bolt is provided on the upper side wall of the support column 403. A limiting hole is formed on the lower outer side wall of the support column 403, and a limiting column 407 is provided on one side of the limiting hole. A movable plate 408 is fixedly connected to one end of the limiting column 407. The movable plate 408 is located at the outer end of the gangway 2 and the telescopic ladder 3, and a pull ring 409 is provided at the outer end of the movable plate 408. A spring 406 is provided on the inner side of the movable plate 408, and the spring 406 is embedded in the outer wall of the gangway plate 2 and the telescopic ladder plate 3.

[0024] In practical use, when it is necessary to extend the telescopic ladder board 3, open the hydraulic telescopic rod 6. The hydraulic telescopic rod 6 drives the support plate 7 to move. Since the support plate 7 is fixedly connected to the telescopic ladder board 3, the hydraulic telescopic rod 6 can drive the telescopic ladder board 3 to move. After the telescopic ladder board 3 is fully extended, lift the handrail 404 out of the storage slot 401. When the handrail 404 is lifted out, pull the moving plate 408 outward through the pull ring 409. The support column 403 and the mounting base 402 rotate. After the handrail 404 is fully erected, release the pull ring 409. The moving plate 408 moves under the action of the spring 406, so that the limiting column 407 is inserted into the limiting hole, thereby limiting and fixing the support column 403 and extending the telescopic ladder board 3.

[0025] When the telescopic ladder 3 needs to be retracted, the handrail 404 is first stored in the storage groove 401, so that the upper end of the handrail 404 is slightly lower than the upper surface of the storage groove 401. Then, the telescopic ladder 3 is moved by the hydraulic telescopic rod 6, so that the telescopic ladder 3 overlaps with the gangway 2, reducing the volume occupied by the equipment.

[0026] In a preferred embodiment, the side walls at both ends of the gangway 2 are provided with limiting grooves 10, and the bottom sides of the telescopic ladder 3 are provided with limiting sliders 11. The limiting sliders 11 are slidably disposed in the limiting grooves 10, and the limiting sliders 11 are integrally formed with the telescopic ladder 3. In actual use, when the telescopic ladder 3 moves, the limiting sliders 11 move in the limiting grooves 10, which not only makes the movement of the telescopic ladder 3 better, but also provides support for the telescopic ladder 3.

[0027] The working principle of this utility model:

[0028] In use, the base 5 is fixed in a suitable position on the hull, and then the hydraulic telescopic rod 6 is opened, which causes the telescopic ladder 3 to extend. When the telescopic ladder 3 moves, the guide ring 9 moves along the guide support column 8, while the limiting slider 11 moves along the limiting groove 10. After the telescopic ladder 3 is fully extended, the pull ring 409 is pulled, and then the handrail 404 is taken out from the storage groove 401, so that the support column 403 at the lower end of the handrail 404 rotates in the mounting seat 402. After the handrail 404 is fully erected, the pull ring 409 is released, and the moving plate 408 moves inward under the action of the spring 406, so that the limiting column 407 is inserted into the limiting hole to achieve the limiting and fixing of the handrail 404. Then, the ship-connecting hook at one end of the telescopic ladder 3 is placed on the ship plate to be connected. People can pass between the two ship plates through the support ladder 1, the gangway 2 and the telescopic ladder 3.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
