Technical Field

[0001] This invention relates to the field of marine technology, specifically to an outward-swinging telescopic gangway. Background Technology

[0002] Gangways are important passageways for personnel to board and disembark from ships. Conventional gangways are mostly of fixed length. When high freeboard ships are equipped with conventional gangways, the gangways will be very long, and storing the gangways will take up a lot of deck space, which is not conducive to deck passage and operation.

[0003] Conventional gangways are usually located on both sides of the ship's side in the residential area. When in use, they can only rotate within the vertical plane of the gangway itself. Due to the ship's shape, they cannot be close to the shore and need to be used in conjunction with a dock ladder. This operation requires renting a shore crane. Therefore, the market urgently needs an outward-swinging telescopic gangway to solve the above problems. Summary of the Invention

The ladder tilting winch 5 has a bevel gear reducer motor embedded inside, and the ladder tilting winch 5 is equipped with a ladder tilting wire rope 9 inside. The ladder tilting wire rope 9 is connected in sequence to the ladder tilting pulley 6 and the ladder tilting pulley 8.

[0027] In this embodiment, specifically: the first step ladder pulley 6 is located on the top of the column fixed to the deck, and the second step ladder pulley 8 is located at the end of the outward swing arm 11 hinged to the deck.

[0028] In this embodiment, specifically: the external swing device 3 is provided with an external swing boom 11, a lifting winch sliding track 12, a sliding roller 13 and a lifting winch 14. The lifting winch 14 is equipped with a safety lock device inside, and the safety lock device is made of high-strength steel.

[0029] In this embodiment, specifically: two sliding rollers 41 and 42 are provided on both sides of the rear of the lower ladder frame 201. The sliding rollers 41 are inserted into the interior of the channel steel on both sides of the upper ladder frame 101. The sliding rollers 41 and 42 slide on the upper and lower surfaces of the lower folded edges of the channel steel on both sides of the upper ladder frame 101.

[0030] In this embodiment, specifically: the front two sides of the upper ladder frame 101 are provided with sliding rollers 31 and 42, two on each side. The sliding rollers 31 are inserted into the interior of the channel steel on both sides of the lower ladder frame 201. The sliding rollers 42 and 31 slide on the upper and lower surfaces of the folded edges on the channel steel on both sides of the lower ladder frame 201.

[0031] In this embodiment, specifically: the sliding rollers and lifting pulleys on the upper ladder frame 101 and the lower ladder frame 201 are respectively provided with base plates. The base plates also serve as limiting baffles for the gangway to extend to its maximum or minimum length. The upper ladder frame 101 is provided with lifting pulley three 17 on both sides of its rear. The lower ladder frame 201 is provided with lifting pulley two 16 and safety pulley 20 on both sides of its rear. The lower ladder frame 201 is provided with an upper platform 23 at its front end. The upper platform 23 is hinged to the lower ladder frame 201.

[0032] In this embodiment, specifically: the outward swing boom 11 and the transmission pipe 24 are kept on the same axis, the ladder tilting winch 5 and the ladder tilting pulley 8 are fixed on the outward swing boom 11 and rotate accordingly, and the track length is customized according to the actual requirements of the ship; during the outward swing of the telescopic gangway body 1, all components that need to swing outward with it, including the lifting winch 14, the lifting pulley 15, the safety eye plate 19, etc., are all centrally fixed and slide in the lifting winch sliding track 12 through the sliding roller 5 13, and move outward in a unified manner.

[0033] In this embodiment, specifically: a lifting winch sliding track 12 is provided on the side of the outward swing boom 11, and a sliding roller 13 is provided on the inner side of the lifting winch sliding track 12. The side of the outward swing boom 11 is connected to the lifting winch 14, the lifting pulley 15, and the safety eye plate 19. The safety eye plate 19, the safety eye plate 21, the safety pulley 20 of the lower ladder frame 201, and the safety wire rope 22 connecting the three constitute an independent high-strength safety rigging. There is one set of safety rigging on each side of the gangway body to ensure that the gangway body can still be suspended on the outward swing device when all the lifting wire ropes 18 break, thereby improving the safety of the gangway. The safety eye plate 19 is connected to the safety wire rope 22, and the lifting winch 14 is equipped with the lifting wire rope 18 inside.

[0035] Working principle or structural principle: In the specific operation of this embodiment, the main actions are flipping, swinging, lowering, and telescopic. The flipping action is performed by the flipping winch 5. The upper platform 23 is connected to the flipping winch 5 through the transmission pipe 24, and the swinging boom 11 is directly connected to the flipping winch 5. The swinging boom 11 flips relative to the upper platform 23. The flipping action is the same as that of a conventional gangway, until the telescopic gangway body 1 and the swinging device 3 are in a horizontal state (e.g., Figure 2 As shown), the outward swing device 3 is operated manually using a telescopic clamp with an extended lever. One end of the clamp only needs to be pressed against the lifting winch 14 to push the outward swing device 3 to the outward swing position (as shown). Figure 3 As shown, the descent and extension actions are completed simultaneously. The descent action is performed by the lifting winch 14. During the descent, the front end of the entire device is hinged to the upper platform 23. The lower ladder 201 can only rotate around the hinge. Through the extension device 2 located between the lower ladder 201 and the upper ladder 101, the upper ladder 101 rotates with the lower ladder 201. As the telescopic gangway body 1 gradually tilts, it will slide relative to the lower ladder 201 by its own weight, thereby realizing the automatic extension function.
