Description

Technical Field

[0001] This utility model relates to the field of marine operation equipment technology, and in particular to a gangway for marine docking. Background Technology

[0002] In offshore operations such as oil extraction, offshore wind power operation and maintenance, and ocean shipping, the transfer of personnel and materials between different vessels or between a vessel and an offshore platform is one of the core operational links. As a key piece of equipment for realizing this transfer function, the safety, stability and adaptability of the gangway directly determine the efficiency and risk of the transfer operation.

[0003] Existing offshore gangways mostly adopt fixed-length rigid structures or simple flexible ladder structures. Among them, the docking mechanism of existing gangways is mostly a simple hook or overlapping structure, which has poor connection stability with ships or platforms and is prone to falling off during ship movement. Furthermore, the lack of effective safety protection measures further exacerbates the operational risks and can easily cause incalculable losses due to falling off. Therefore, a new type of gangway for offshore docking is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a gangway for offshore docking, in order to solve the problems mentioned in the background art.

[0005] To solve the above problems, the following technical solution is provided: a gangway for marine docking, comprising a fixed base, guardrails fixedly installed on both sides of the upper end of the fixed base, and multiple equidistant gangway plates fixedly installed inside the fixed base. A limiting structure is provided at one end of the fixed base, the limiting structure comprising positioning frames fixedly installed on both sides of the outer wall of the fixed base, a rotating handwheel fixedly installed on the upper end of each positioning frame, a guide screw fixedly installed at the bottom of the rotating handwheel, a positioning plate rotatably connected to one end of the guide screw, two anti-fall hooks symmetrically installed on the inner wall of one end of the fixed base, and two support blocks symmetrically installed on the front side of one end of the fixed base, and a telescopic structure is provided inside the fixed base.

[0006] As a preferred embodiment of the above technical solution, the two positioning frames are symmetrically slidably connected to the guide screws, and one end of each guide rod is fixedly installed on the upper end of the positioning plate. An anti-slip pad is fixedly installed on the bottom of the positioning plate.

[0007] As a preferred embodiment of the above technical solution, a limit cylinder is fixedly installed on the upper end of each of the two support blocks, and a positioning pressure plate is fixedly installed on one end of each limit cylinder, with the positioning pressure plate in contact with the ground.

[0008] As a preferred embodiment of the above technical solution, rubber pads are fixedly attached to both sides of the bottom of the fixed base, and a displacement sensor is fixedly installed on the inner wall of the fixed base.

[0009] As a preferred embodiment of the above technical solution, the telescopic structure includes locking cylinders fixedly installed on both sides of the inner wall of the fixed base. One end of each locking cylinder is fixedly installed on one end of the auxiliary gangway frame, and a buffer pad is fixedly installed at the bottom of the auxiliary gangway frame.

[0010] As a preferred embodiment of the above technical solution, guide grooves are provided on both sides of the inner wall of the fixed base, and guide sliders are fixedly installed on both sides of the outer wall of the auxiliary gangway frame, with the guide sliders slidably connected inside the guide grooves.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model device is equipped with a limiting structure. By rotating two handwheels, the positioning plate on the guide screw moves downward along the positioning frame. When the positioning plate moves, it slides on the positioning frame with two guide rods to contact the ground. At the same time, the limiting cylinders on the two support blocks drive the positioning pressure plate to move downward to contact the ground, thereby further limiting and supporting the gangway. Through the combination of the limiting structure and the anti-fall hook, rapid and accurate positioning is achieved, ensuring that the gangway will not fall off due to the movement of the ship after docking, thus improving the positional stability of the gangway during operation.

[0012] 2. The device of this utility model is equipped with a telescopic structure. By driving two locking cylinders, the auxiliary gangway frame slides and is limited in the guide groove through the guide slider, so as to make the auxiliary gangway frame telescopically adjustable. It can adapt to the distance between the ship and the receiving object under different operating scenarios, improve the application range of the gangway, and is easy to operate.

It should be understood that the embodiments of the present invention are not limited in scope.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1 to 4 As shown in the figure, this embodiment provides a design for a gangway for sea docking, including a fixed base 1. Guardrails 2 are fixedly installed on both sides of the upper end of the fixed base 1, and multiple equidistant gangway plates 3 are fixedly installed inside the fixed base 1. A limiting structure 4 is provided at one end of the fixed base 1. The limiting structure 4 includes positioning frames 41 fixedly installed on both sides of the outer wall of the fixed base 1. A rotating handwheel 42 is fixedly installed on the upper end of the positioning frame 41. A guide screw 43 is fixedly installed at the bottom of the rotating handwheel 42. A positioning plate 44 is rotatably connected to one end of the guide screw 43. Two anti-fall hooks 5 are symmetrically installed on the inner wall of one end of the fixed base 1, and two support blocks 47 are symmetrically installed on the front side of one end of the fixed base 1. A telescopic structure 7 is provided inside the fixed base 1.

[0018] like Figures 2 to 3 As shown, guide rods 46 are symmetrically slidably connected to guide screws 43 inside the two positioning frames 41. One end of each guide rod 46 is fixedly installed on the upper end of the positioning plate 44. Anti-slip pads 45 are fixedly installed on the bottom of the positioning plate 44. Rubber pads 9 are fixedly attached to both sides of the bottom of the fixed base 1. Displacement sensors 8 are fixedly installed on the inner wall of the fixed base 1.

[0019] By setting a displacement sensor 8 and electrically connecting it to the controller, which is an existing mature technology, this application does not elaborate further. At the same time, when the guide screw 43 drives the positioning plate 44 to move, the two guide rods 46 are used to slide and limit the movement. Anti-slip pads 45 and rubber pads 9 are also set to provide effective protection when in contact with the ground, thereby improving installation stability.

[0020] like Figure 4 As shown, the telescopic structure 7 includes locking cylinders 71 fixedly installed on both sides of the inner wall of the fixed base 1. One end of each locking cylinder 71 is fixedly installed on one end of the auxiliary gangway frame 72. A buffer pad 74 is fixedly installed at the bottom of the auxiliary gangway frame 72. Guide grooves 6 are provided on both sides of the inner wall of the fixed base 1. Guide sliders 73 are fixedly installed on both sides of the outer wall of the auxiliary gangway frame 72 and the guide sliders 73 are slidably connected inside the guide grooves 6.

[0021] By setting a buffer pad 74 at one end of the auxiliary gangway frame 72, which is made of rubber material, it is easy to buffer when in contact with the ground. At the same time, when the auxiliary gangway frame 72 is extended or retracted, it slides in the guide groove 6 through the guide slider 73, which is convenient to limit the movement of the auxiliary gangway frame 72.

[0022] The working principle and process of this utility model are as follows: When it is necessary to connect the gangway to the ground, the drive motor first drives the gangway to rotate and position it relative to the ground. The telescopic anti-fall hook 5 is then engaged with the railing. Then, by rotating the two handwheels 42, the positioning plate 44 on the guide screw 43 moves downward along the positioning frame 41. When the positioning plate 44 moves, it slides on the positioning frame 41 using the two guide rods 46 to contact the ground. The anti-slip pad 45 increases the friction between the plate and the ground. At the same time, the limit cylinders 48 on the two support blocks 47 drive the positioning pressure plate 49 to move downward and contact the ground, thereby further limiting and supporting the gangway and achieving stability in use. When it is necessary to adjust the length of the gangway, the displacement sensor 8 is used to monitor the distance. By driving the two locking cylinders 71, the auxiliary gangway frame 72 slides in the guide groove 6 through the guide slider 73 to limit the movement, thereby enabling the extension and retraction adjustment of the auxiliary gangway frame 72. This can adapt to changes in the distance and position between the ship and the docking object under different operating scenarios.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
