[0032] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiment of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application. The embodiments of the present application are described in detail below in conjunction with the drawings.

[0033] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are orientations or positional relationships based on the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0035] The terms "first", "second" and "third" (if any) in the specification and claims of this application and the above drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0036] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or display comprising a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or display.

[0037] In the prior art, after the transport ship reaches the ladder position, it will collide with the ladder of the offshore wind turbine or the offshore booster station. However, the transport ship will float up and down on the sea due to wind and waves, resulting in an instantaneous height difference between the transport ship and the ladder. When the operation and maintenance personnel climb from the ship to the ladder, there is a risk of falling into the sea and being pinched.

[0038] After repeated thinking and verification, the inventor found that if a landing device is installed on the hull of a transport ship, the landing device includes a support plate, a buffer assembly and a connection assembly. The support plate can be connected to the ladder through the connection assembly, and the buffer assembly is arranged between the support plate and the hull of the transport ship. When the wind and waves drive the transport ship to float up and down, the buffer assembly can absorb the kinetic energy of the transport ship, making the support plate more stable relative to the transport ship, thereby reducing the instantaneous height difference between the support plate and the ladder. When the transport ship reaches the ladder position, the operation and maintenance personnel can stand on the support plate and then climb from the support plate to the ladder, thereby improving the safety of the operation and maintenance personnel in the process of climbing from the ship to the ladder.

[0039] The technical solutions of the ship-mounted staging device and the transport ship provided in the embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0040] Reference Figure 1 and Figure 2 As shown, the ship staging device provided by the embodiment of the present application includes a support plate 100, a plurality of buffer assemblies 200 and a plurality of connection assemblies 300. One end of each buffer assembly 200 is connected to the support plate 100, and the other end of each buffer assembly 200 is connected to the transport ship. The connection assembly 300 is located on the side of the support plate 100 away from the buffer assembly 200. The connection assembly 300 includes a first connection member 310 and a second connection member 320, one end of the first connection member 310 is connected to the support plate 100, and the second connection member 320 is installed at the other end of the first connection member 310, and the second connection member 320 is configured to be connected to the ladder 20.

[0041] The number of buffer components 200 is non-limiting. For example, Figure 1 As shown in the figure, the number of buffer components 200 can be four, and the four buffer components 200 can be arranged in two rows and two columns. In a possible implementation, one end of each buffer component 200 can be fixed to the support plate 100 by a fastener, and the other end of each buffer component 200 can be connected to the deck of the bow of the transport ship. It is worth mentioning that when the wind and waves drive the transport ship to float up and down, the buffer component 200 can absorb the impact of the hull 10 and play a buffering role.

[0042] Exemplarily, the number of the connection assemblies 300 may be two, and the two connection assemblies 300 are arranged at intervals on the support plate 100. When the transport ship reaches the position of the ladder 20, the two connection assemblies 300 are respectively connected to the ladder 20. In a specific embodiment, when the transport ship reaches the position of the ladder 20, the second connection member 320 of each connection assembly 300 can be connected to the crossbeam of the ladder 20. It can be understood that when the connection assembly 300 is connected to the ladder 20, the support plate 100 can be limited by the connection assembly 300.

[0043] The marine staging device provided in this embodiment includes a support plate 100, a plurality of buffer components 200 and a connecting component 300. Each buffer component 200 is connected between the support plate 100 and the transport ship. The support plate 100 can be connected to the ladder 20 on the platform through the connecting component 300. When the transport ship reaches the position of the ladder 20, the operation and maintenance personnel can connect the second connecting member 320 of the connecting component 300 to the ladder 20. When the hull 10 of the transport ship floats up and down due to wind and waves, each buffer component 200 can play a buffering role, so that the support plate 100 is more stable than the hull 10, and the instantaneous height difference between the support plate 100 and the ladder 20 is small. The operation and maintenance personnel can first stand on the support plate 100, and then climb from the support plate 100 to the ladder 20, which improves the safety of the operation and maintenance personnel in the process of climbing from the ship to the ladder 20.

[0044] In addition, when the second connecting member 320 is connected to the ladder 20, the maintenance personnel can directly climb to the ladder 20 via the ship-mounted platform device, without having to wait until the hull 10 floats to the highest point before climbing the ladder 20, which is conducive to improving the operation efficiency of the maintenance personnel logging on to the platform and realizing rapid login to the platform. In weather with strong winds and waves, the maintenance personnel can also perform the platform operation.

[0045] In one embodiment, Figure 1 and Figure 2 As shown, the buffer assembly 200 includes a damper 210 and a first elastic member 220 sleeved on the damper 210. The damper 210 is connected between the support plate 100 and the transport ship, and two ends of the first elastic member 220 are connected to two ends of the damper 210 respectively.

[0046] Exemplarily, the damper 210 can be a friction damper, a liquid damper or a gas damper, which is not the only limitation in this embodiment. The top of the damper 210 can be fixedly connected to the support plate 100 by a fastener. In a possible implementation, the damper 210 includes a cavity seat and a piston rod, and one end of the piston rod provided with a piston extends into the interior of the cavity seat and can slide relative to the cavity seat. After the first elastic member 220 is sleeved on the damper 210, its two ends can be respectively connected to the cavity seat and one end of the piston rod extending out of the cavity seat.

[0047] In this embodiment, when the wind and waves drive the hull 10 of the transport ship to float up and down, the first elastic member 220 absorbs the kinetic energy of the hull 10, which plays a buffering role. After the first elastic member 220 absorbs the kinetic energy, the damping effect of the damper 210 can reduce the rebound of the first elastic member 220, making the support plate 100 more stable. In other words, the above arrangement can make the support plate 100 more stable relative to the hull 10.

[0048] Continue to refer to Figure 1 and Figure 2The ship staging device further includes a plurality of parallel guide rails 400 , each guide rail 400 is installed on the transport ship, and each buffer assembly 200 is configured to be able to move on the corresponding guide rail 400 along the extension direction of the guide rail 400 .

[0049] For example, Figure 1 As shown, the number of guide rails 400 can be two, each guide rail 400 extends along the width direction of the transport ship, and accordingly, the plurality of buffer assemblies 200 are divided into two groups, and the two groups of buffer assemblies 200 are respectively connected to the two guide rails 400. Specifically, the two buffer assemblies 200 located on the front side of the support plate 100 are connected to the guide rails 400 on the front side of the transport ship, and the two buffer assemblies 200 located on the rear side of the support plate 100 are connected to the guide rails 400 on the rear side of the transport ship. Of course, the number of guide rails 400 can also be three or four, etc., which is not limited here. It can be understood that the plurality of buffer assemblies 200 are divided into multiple groups, and the multiple groups of buffer assemblies 200 are connected to the plurality of guide rails 400 in a one-to-one correspondence.

[0050] Through the above arrangement, when the hull 10 of the transport ship is driven by wind and waves to move left and right, the support plate 100 can move relative to the hull 10, so that the support plate 100 can be relatively stable with the ladder 20. The guide rails 400 can guide and limit the support plate 100. In addition, the number of guide rails 400 is set to ensure the stability of the support plate 100 and prevent the support plate 100 from tipping over when moving relative to the hull 10.

[0051] like Figure 1 and Figure 2 As shown, each buffer assembly 200 has a roller 500 rotatably mounted on one end away from the support plate 100 , and the roller 500 is configured to roll on the corresponding guide rail 400 .

[0052] Exemplarily, two rollers 500 are rotatably mounted on one end of the buffer assembly 200 away from the support plate 100, and the two rollers 500 are respectively located on opposite sides of the buffer assembly 200. It is worth mentioning that when the roller 500 rolls on the corresponding guide rail 400, the guide rail 400 can limit the roller 500, that is, the roller 500 can only roll along the extension direction of the guide rail 400 on the guide rail 400.

[0053] By installing the roller 500 on the buffer assembly 200 , the friction between the buffer assembly 200 and the guide rail 400 can be reduced when the buffer assembly 200 moves along the extension direction of the guide rail 400 , so that the support plate 100 can move more smoothly relative to the hull 10 .

[0054] In other embodiments, a slider is fixedly mounted on one end of each buffer assembly 200 away from the support plate 100 , and each slider is slidably connected to a corresponding guide rail 400 .

[0055] For example, Figure 1 and Figure 2 As shown, the guide rail 400 is provided with a guide groove 410 for accommodating the roller 500. The opening 411 of the guide groove 410 faces the support plate 100, and the two opposite sides of the opening 411 are respectively provided with limit plates 420, with a gap between the two limit plates 420, and the buffer assembly 200 is arranged through the gap between the two limit plates 420.

[0056] The length direction of the guide groove 410 is parallel to the extension direction of the guide rail 400, and the opening 411 of each guide groove 410 is located at the top of the corresponding guide rail 400. When the roller 500 is accommodated in the corresponding guide groove 410, the guide groove 410 can limit the movement direction of the roller 500, so that the roller 500 can only move along the length direction of the guide groove 410. Each limiting plate 420 is fixed to the main part of the guide rail 400 by welding. It can be understood that in the vertical direction, the projection of the limiting plate 420 and the projection of the roller 500 at least partially overlap, that is, the limiting plate 420 can be against the roller 500. When assembling the marine staging device, each roller 500 can be placed into the guide groove 410 from the end of the guide rail 400.

[0057] In this structure, the guide rail 400 can limit the movement direction of the roller 500 through the guide groove 410. When the wind and waves drive the hull 10 of the transport ship to float up and down, the limiting plate 420 can prevent the roller 500 from escaping from the corresponding guide groove 410.

[0058] like Figure 2 As shown, the buffer assembly 200 includes a bracket 230, and the bracket 230 is located at one end of the buffer assembly 200 away from the support plate 100. The bracket 230 includes a first connecting section 231 and a second connecting section 232, one end of the first connecting section 231 is connected to the buffer assembly 200, and the other end of the first connecting section 231 is connected to the middle of the second connecting section 232, and rollers 500 are rotatably mounted on both ends of the second connecting section 232.

[0059] Exemplarily, when the buffer assembly 200 includes the damper 210 , the first elastic member 220 , and the bracket 230 , the bracket 230 may be fixedly mounted on the bottom end of the damper 210 by welding. Figure 2 It is shown that the top end of the first connecting section 231 is connected to the damper 210, and the bottom end of the first connecting section 231 is connected to the middle of the second connecting section 232. The first connecting section 231 and the second connecting section 232 form a "T"-shaped structure, wherein the first connecting section 231 and the second connecting section 232 can be fixed by welding. Each roller 500 can be rotatably mounted on the end of the second connecting section 232 by a rotating shaft.

[0060] The roller 500 can be rotatably mounted on the buffer assembly 200 through the bracket 230. In addition, the bracket 230 can also avoid interference between the roller 500 and the buffer assembly 200, ensuring that the roller 500 can rotate smoothly. Specifically, the length of the first connecting section 231 can exceed the radius of the roller 500, or the roller 500 can be installed at the widest position of the buffer assembly 200 through the second connecting section 232 to avoid the buffer assembly 200 hindering the rotation of the roller 500.

[0061] In one embodiment, Figure 1 As shown, the first connecting member 310 is a traction rope, and the traction rope is configured to apply an upward pulling force to the support plate 100 .

[0062] The length of the towing rope can be set as needed and is not limited here. In a possible implementation, a mounting seat for tying the towing rope can be installed on the top of the support plate 100, and the second connecting member 320 can be tied and fixed to the end of the towing rope away from the support plate 100. After the transport ship reaches the position of the ladder 20, the operation and maintenance personnel can fix the second connecting member 320 on the towing rope to the ladder 20 when the hull 10 floats to the highest position, so that when the wind and waves drive the hull 10 to float up and down, the towing rope can stably apply an upward pulling force to the support plate 100.

[0063] A traction rope is used as the first connecting member 310 . Since the traction rope has certain flexibility, it can be bent as needed, so that the operation and maintenance personnel can fix the second connecting member 320 on the traction rope to the ladder 20 .

[0064] In other embodiments, a support rod may be used as the first connecting member 310, the bottom end of the support rod is fixedly mounted on the supporting plate 100, and the second connecting member 320 may be rotatably mounted on the top end of the support rod via a rotating shaft.

[0065] In a specific embodiment, Figure 1 and Figure 3 As shown, the second connecting member 320 is a hook 321 installed at the end of the traction rope away from the support plate 100.

[0066] When the transport ship reaches the position of the ladder 20, the operation and maintenance personnel can hang the hook 321 on the crossbeam of the ladder 20. In a possible implementation, a connecting ring for hanging the hook 321 is installed on the ladder 20, and when the hook 321 is hung on the connecting ring, the hook 321 can be prevented from moving relative to the ladder 20 along the extension direction of the crossbeam.

[0067] This structure uses a hook 321 as the second connecting member 320 to facilitate the connection between the connecting assembly 300 and the ladder 20.

[0068] In other embodiments, a connection seat can be used as the second connection member 320, and a through hole for a fastener to pass through can be provided on the connection seat. Accordingly, a plurality of internal threaded holes for fasteners to lock can be provided on the ladder 20. When the transport ship reaches the position of the ladder 20, the connection seat can be locked to the ladder 20 using fasteners.

[0069] In a more specific embodiment, Figure 3 As shown, the second connecting member 320 also includes a limiting member 322 and a second elastic member (not shown). One end of the limiting member 322 is rotatably mounted on the hook 321, the second elastic member is connected between the hook 321 and the limiting member 322, and the second elastic member is configured to drive the other end of the limiting member 322 to abut against the free end of the hook 321.

[0070] The limiting member 322 may be a strip structure, one end of which may be rotatably mounted on the hook 321 via a rotating shaft. The second elastic member may be a torsion spring, which is sleeved on the rotating shaft between the limiting member 322 and the hook 321, one end of which is connected to the hook 321, and the other end of which is connected to the limiting member 322. When the operation and maintenance personnel are hanging the hook 321, the crossbeam or connecting ring of the ladder 20 may pass over the limiting member 322 and enter the interior of the hook 321. When the crossbeam extends into the interior of the hook 321, the second elastic member drives the other end of the limiting member 322 to abut against the free end of the hook 321.

[0071] The above arrangement can ensure the stability of the connection between the hook 321 and the ladder 20 , thereby preventing the hook 321 from falling off the ladder 20 .

[0072] The present application also provides a transport ship, comprising a hull 10 and the above-mentioned ship boarding device, wherein the ship boarding device is installed on the hull 10.

[0073] The transport ship provided in the present application is equipped with the above-mentioned ship-mounted staging device. When the transport ship reaches the position of the ladder 20, the operation and maintenance personnel can climb the ladder 20 via the ship-mounted staging device. The operation and maintenance personnel are safer when climbing from the ship to the ladder 20.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
