Description

Technical Field

[0001] This utility model relates to the technical field of ship personnel passage devices, and in particular to a ship personnel passage device. Background Technology

[0002] Currently, offshore wind power operation and maintenance personnel primarily use rigid gangways for transfers between vessels and fixed platforms, or between vessels themselves. When waves cause significant relative heave or lateral movement between vessels and platforms, or between vessels, the ends of the gangways are prone to rigid collisions, jamming, or even structural damage, posing a threat to both personnel safety and equipment. It is evident that rigid gangways cannot effectively adapt to relative motion caused by waves, exposing personnel to the risk of falls and crushing, lacking effective shock absorption, and causing intense turbulence and instability during passage.

[0023] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0024] like Figure 1 and Figure 2 As shown, the ship personnel passage device of this utility model embodiment includes a first bridge body 1, a second bridge body 2 and a third bridge body 3.

[0025] The first bridge body 1 includes a first box body 11, a first plate body 12 and a first buffer member 13. The first plate body 12 is spaced on the first box body 11. The upper end of the first buffer member 13 is installed on the first plate body 12 and the lower end of the first buffer member 13 is installed on the first box body 11. The rear end of the first box body 11 has a first through hole 111.

[0026] The second bridge body 2 includes a second box body 21, a second plate body 22, and a second buffer member 23. The second plate body 22 is spaced apart on the second box body 21. The upper end of the second buffer member 23 is installed on the second plate body 22, and the lower end of the second buffer member 23 is installed on the second box body 21. The rear end of the second box body 21 has a second through hole 211, and the front end of the second bridge body 2 is slidably inserted through the first through hole 111.

[0027] The third bridge body 3 includes a third box body 31, a third plate body 32 and a third buffer member 33. The third plate body 32 is spaced on the third box body 31. The upper end of the third buffer member 33 is installed on the third plate body 32 and the lower end of the third buffer member 33 is installed on the third box body 31. The front end of the third bridge body 3 slides through the second through hole 211.

[0028] In use, the first bridge body 1 is placed on a ship, the second bridge body 2 and the third bridge body 3 are pulled out in sequence, and the third bridge body 3 is placed on another ship or a fixed platform. Then, at least one of the first bridge body 1 and the third bridge body 3 is fixed in position, thus forming a continuous passage that can be walked on.

[0029] Based on the above structural configuration, the second bridge body 2 extends and retracts within the first box 11, the third bridge body 3 extends and retracts within the second box 21, the first plate 12 is damped by the first buffer 13, the second plate 22 is damped by the second buffer 23, and the third plate 32 is damped by the third buffer 33, thus achieving both extension and damping effects to ensure safe passage.

The third foam board 34 has a third through hole 341, and a third buffer member 33 is disposed within the third through hole 341. Thus, the third foam board 34 can absorb the impact of the third plate 32, further improving the shock absorption effect. The third buffer member 33 extends from its upper end through the third through hole.

[0035] like Figure 1 and Figure 2 As shown, in some embodiments, a fourth bridge body 4 is also included. The fourth bridge body 4 includes a fourth box body 41, a fourth plate body 42, a fourth foam board 44, and a fourth buffer member 43.

The fourth foam board 44 has a fourth through hole 441, and the fourth buffer member 43 is disposed in the fourth through hole 441. The upper end of the fourth buffer member 43 is mounted on the fourth plate body 42, and the lower end of the fourth buffer member 43 is mounted on the fourth box body 41. The rear end of the fourth box body 41 is hinged to the front end of the first box body 11. In this way, the fourth bridge body 4 and the first bridge body 1 can be bent at an angle, which is beneficial for use when there is a height difference.

[0036] like Figure 1 and Figure 2As shown, in some embodiments, a fifth bridge body 5 is also included. The fifth bridge body 5 includes a fifth box body 51, a fifth plate body 52, a fifth foam board 54, and a fifth buffer member 53.

The fifth foam board 54 has a first through hole 541, and the fifth buffer member 53 is disposed in the fifth through hole 541. The upper end of the fifth buffer member 53 is mounted on the fifth plate body 52, and the lower end of the fifth buffer member 53 is mounted on the fifth box body 51. The front end of the fifth box body 51 is hinged to the rear end of the third box body 31. In this way, the fifth bridge body 5 and the third bridge body 3 can be bent at an angle, which is beneficial for use when there is a height difference.

[0037] like Figure 2 As shown, in some embodiments, a first hinge 6 and a second hinge 7 are also included. The rear end of the fourth housing 41 is hinged to the front end of the first housing 11 via the first hinge 6, and the front end of the fifth housing 51 is hinged to the rear end of the third housing 31 via the second hinge 7. Both the first hinge 6 and the second hinge 7 are hinge shaft and bearing structure. Specifically, when the first hinge 6 is installed, the bearing is fixed to the fourth housing 41, the hinge shaft is installed on the bearing and its two ends are fixed to the side walls of the first housing 11, allowing rotation between the fourth housing 41 and the first housing 11. When the second hinge 7 is installed, the bearing is fixed to the fifth housing 51, the hinge shaft is installed on the bearing and its two ends are fixed to the side walls of the third housing 31, allowing rotation between the fifth housing 51 and the first housing 11.

[0038] like Figure 5 As shown, in some embodiments, the first buffer 13, the second buffer 23, the third buffer 33, the fourth buffer 43, and the fifth buffer 53 are all spring seats. Each spring seat includes a spring 131, a baffle 132, and a mounting base 133.
