Description

Technical Field

[0001] The utility model relates to the technical field of ship outfitting, in particular to an electric weathertight gangway. Background Technique

[0002] When the ship is docked, due to the undulation of river waves and the different heights between the ship's middle door and the dock caused by different hull sizes, in order to ensure the safety of personnel getting on and off the ship, a gangway needs to be installed. Installing a gangway on the side of a large passenger ship can disperse the passenger flow and improve the efficiency of getting on and off the ship.

[0003] At present, the existing gangways for passenger ships are mechanical gangways and hydraulic gangways. The gangway of a large ship is large in volume and weight. The mechanical gangway requires manual operation, which is difficult. Most of the existing gangways use hydraulic rods for retraction and extension. The hydraulic cylinders are large in volume and occupy space, and it is difficult for the hydraulic push cylinders to drive the gangway to respond in time to the vertical relative movement between the ship and the dock, and the gangway cannot be retracted and extended in time, resulting in the risk of the gangway being separated from the dock, which is likely to cause tourists to be injured. At the same time, when the hydraulic rod fails, the gangway cannot be opened, posing a safety hazard. Content of the Utility Model

[0004] The purpose of the utility model is to provide an electric weathertight gangway to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following will describe in detail various exemplary embodiments, features, and aspects of the present application with reference to the accompanying drawings. The same reference numerals in the drawings denote elements having the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings do not have to be drawn to scale unless otherwise specified.

[0031] The special word "exemplary" here means "serving as an example, embodiment, or illustrative". Any embodiment described as "exemplary" here does not have to be construed as superior or better than other embodiments.

[0032] In addition, for better illustration of the present application, numerous specific details are given in the following specific embodiments. Those skilled in the art should understand that the present application can also be implemented without certain specific details. In some instances, methods, means, and components well-known to those skilled in the art are not described in detail so as to highlight the gist of the present application.

[0033] Please refer to Figures 1 - 4 , in the embodiment of the present utility model, an electric weathertight gangway includes a bulwark 9 fixed on the main deck 15 and arranged in an inclined shape, and a passage is formed on the bulwark 9;

[0034] It further includes a gangway body 7 hinged on the bulwark 9 and used for blocking the passage;

[0035] A hoisting mechanism, installed at the side end of the bulwark 9 and connected to the gangway body 7, for controlling the rotation of the gangway body 7 relative to the bulwark 9;

[0036] A pushing unit, installed on the bulwark 9, for pushing the gangway body 7 to rotate from an inclined state towards a vertical state when the gangway body 7 is opened;

[0037] A locking device, provided with at least one, installed on the bulwark 9, for pressing on the gangway body 7 when the gangway body 7 is closed.

[0038] In this embodiment, when the gangway body 7 is closed, it is placed in an inclined state facing the bulwark 9, which can, to a certain extent, eliminate the problem that the gangway body 7 is likely to be accidentally opened when placed vertically. By synchronously controlling the opening and closing of the gangway body 7 through the arranged pushing unit and hoisting mechanism, the pushing unit pushes the gangway body 7 outwards to open the gangway body 7, and the hoisting mechanism controls the opening speed of the gangway body 7 to ensure smooth opening of the gangway body and reduce the possibility of damage to the gangway body 7; at the same time, the arranged locking device can prevent the gangway body 7 from being accidentally opened during navigation and, to a certain extent, avoid the shaking of the gangway body 7, with high safety.

[0039] Among them, it should be supplemented that a groove is formed on the bulwark 9, and one end of the gangway body 7 is rotatably installed in the groove through a hinge 13, so as to eliminate the height difference between the gangway body 7 and the main deck 15 due to the thickness of the main deck 15 and the height of the sleeve.

[0040] The above-mentioned hoisting mechanism, pushing unit, and locking device are in communication with the controller 10. By setting the controller 10, the hoisting mechanism, pushing unit, and locking device are controlled to perform corresponding actions. The controller 10 in this embodiment adopts a PLC control system. The PLC control system has few connections, small volume, low power consumption, long service life, and has high reliability, powerful functions and flexibility, and high scalability and maintainability. The opening and closing of the gangway body 7 can be switched and controlled by the cab console and the controller 10 beside the gangway body 7.

[0041] Furthermore, the locking device includes a locking structure 5, a second hydraulic push rod 6 and a limit plate 16, the locking structure 5 connects the second hydraulic push rod 6 and the limit plate 16, and when the second hydraulic push rod 6 is actuated, the locking structure 5 drives the limit plate 16 to move toward the springboard body 7, so that the limit plate 16 is pressed against the springboard body 7.

[0042] Exemplarily, in one embodiment, the locking structure 5 includes a fixing plate 503 fixed on the bulwark 9, and a gap is formed between the fixing plate 503 and the bulwark 9;

[0043] It also includes two parallel rotating plates 502 that penetrate the gap and can move in the gap, the rotating plates 502 are formed with strip-shaped through grooves along their length direction, a fixing column is fixed in the gap, the fixing column penetrates the strip-shaped through groove, one end of the rotating plate 502 is rotatably mounted with a driving plate 501, and the other end is rotatably connected to the limiting plate 16, the driving plate 501, the limiting plate 16 and the two rotating plates 502 together form a parallelogram structure;

[0044] The second hydraulic push rod 6 is installed on the bulwark 9 , and the movable end of the second hydraulic push rod 6 is connected to the driving plate 501 .

[0045] The driving plate 501 is driven to move by controlling the telescopic movement of the first hydraulic push rod 6. When the driving plate 501 moves, the limit plate 16 is moved in combination with the deformation characteristics of the parallelogram and the connection state between the rotating plate 502 and the fixed plate 503 to press against the side of the springboard body 7 away from the bulwark 9, thereby achieving the limit fixation of the springboard body 7.

[0046] It should be particularly noted that the length direction of the second hydraulic push rod 6 is parallel to the length direction of the side of the springboard body 7 after it is closed.

[0047] The pushing unit described above includes a first hydraulic push rod 4 installed on the bulwark 9, and the movable end of the first hydraulic push rod 4 abuts against the springboard body 7 when the springboard body 7 is closed. When the springboard body 7 starts, the first hydraulic push rod 4 pushes the springboard body 7 to rotate from an inclined state to a vertical direction, and when the rotation exceeds the vertical state, the springboard body 7 can continue to rotate under the action of its own weight. At this time, the first hydraulic push rod 4 retracts.

[0048] For further information, see Figure 1 , the hoisting mechanism comprises:

[0049] A winch 1 installed on the bulwark 9 and a steel wire rope 2 connected to the winch 1;

[0050] The pulley block 3, the end of the steel wire rope 2 away from the winch 1 passes over the pulley block 3 and is fixedly connected to the fixed wheel 17 installed on the bulwark 9.

[0051] Specifically, the pulley block 3 includes two groups of pulley units symmetrically arranged, and the pulley unit includes a second pulley 302 installed on the gangway body 7, a first pulley 301 and a third pulley 303 installed on the bulwark 9, and the wire rope 2 led out from the winch 1 passes through the third pulley 303, the second pulley 302, the first pulley 301, the first pulley 301, the second pulley 302 and the third pulley 303 in sequence and is fixed to the fixed wheel 17.

[0052] By setting two sets of pulley units, pulling is achieved on both sides of the springboard body 7 to ensure that the springboard body 7 is evenly stressed when opening or closing. When the springboard body 7 rotates through the vertical state under the action of the first hydraulic push rod 4, the winch 1 continues to maintain the unwinding state and slowly rotates downward under the deadweight of the springboard body 7. At the same time, the downward rotation speed of the springboard body 7 can be controlled by controlling the unwinding speed of the winch 1. When the winch 1 reels the wire rope 2, the closing control of the springboard body 7 can be achieved.

[0053] For further information, see Figure 2 The bulwark 9 is arranged on one side of the main deck 15, an arc-shaped transition plate 14 is arranged between the gangway body 7 and the main deck 15, and a triangular transition plate 12 is hinged on the upper end of the gangway body 7 when it is placed vertically.

[0054] The arc-shaped transition plate 14 can effectively eliminate the gap between the gangway body 7 and the main deck 15, and the triangular transition plate 12 can effectively eliminate the height difference between the gangway body 7 and the dock 11, which facilitates the passage of people and wheelchairs and eliminates the unsafe factors caused by the steps.

[0055] For further information, see Figure 1 , Figure 3 and Figure 4 When the gangway body 7 is closed, a foldable handrail 8 is symmetrically installed on one side facing the bulwark 9. The handrail 8 includes a connecting rod 802 and a handrail 801 fixed on the gangway body 7. One end of the handrail 801 facing the gangway body 7 is hinged to the connecting rod 802. A latch 804 is movably provided on the handrail 801. A sleeve 803 is provided on the connecting rod 802. When the handrail 801 abuts against the end of the connecting rod 802, the latch 804 is inserted into the sleeve 803 to achieve fixation.

[0056] By setting the handrail 8 to be a foldable structure, it is convenient to fold the handrail 8 after the gangway body 7 is closed, so as to reduce the space occupied by the handrail 8.
