Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a foldable gangway crane and a cruise ship containing the same. Background Technology

[0002] Once a cruise ship docks, gangways need to be installed on both sides of the vessel for passengers to board and disembark. Because the gangways are stored on racks on the sides of the ship, they are quite large and heavy, and the space available for hoisting them is limited. Therefore, a foldable gangway crane is needed for transporting the gangways. Currently, shipboard gangway cranes are too large and inflexible to be folded, making them unsuitable for cruise ships. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defects in the prior art and provide a foldable gangway crane.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A foldable gangway crane includes a folding assembly and at least two foldable modules, adjacent foldable modules are connected by the folding assembly, and a lifting structure is provided on each foldable module;

[0006] The folding assembly includes a pivot and several folding plates, which are respectively fixed to the ends of adjacent foldable modules. Each folding plate has a through hole, and the through holes on adjacent folding plates are aligned to form a connecting hole. The pivot is disposed in the connecting hole.

[0007] In this technical solution, at least two foldable modules are incorporated into the foldable gangway crane. Adjacent foldable modules are connected by folding components, and a lifting structure is provided on each foldable module. When the foldable gangway crane is needed for lifting the gangway, it can be unfolded for lifting; when it is not needed, it can be folded up for storage. Furthermore, due to its foldable function, during the lifting process, the foldable gangway crane gradually unfolds as it lifts the gangway outwards, occupying relatively little space throughout the process.

[0008] Preferably, the foldable gangway crane includes a first foldable module, a second foldable module, and two sets of coaxially arranged rotating connection components. The first foldable module and the second foldable module are located at both ends of the foldable gangway crane, and the lifting structure is disposed on the first foldable module.

[0009] The rotating connection assembly is located at the end of the second foldable module away from the first foldable module, and the second foldable module can be rotatably connected to the bulkhead through the rotating connection assembly.

[0010] In this technical solution, by setting the lifting structure and connecting components on the first foldable module and the second foldable module located at both ends of the entire foldable gangway crane, the maximum lifting distance of the foldable gangway crane can be increased.

[0011] Preferably, the rotating connection assembly includes a first connecting plate, a second connecting plate, and a connecting shaft. The first connecting plate is fixed to the second foldable module, and the second connecting plate is rotatably connected to the first connecting plate via the connecting shaft. The second connecting plate is used to fix the assembly to the bulkhead.

[0012] Preferably, the first connecting plate includes a first part and a second part, and the first part and the second part have an included angle α, the value of which is between 120° and 160°.

[0013] The connecting assembly further includes a third connecting plate, which connects two of the second connecting plates and is capable of contacting the bulkhead surface.

[0014] In this technical solution, by setting the first connector and the second connector to have an included angle, the foldable gangway can be fixed to the bulkhead facing the cabin exit.

[0015] Preferably, there are two first connecting plates, which are spaced apart along the axial direction of the connecting shaft; and there are two second connecting plates, which are spaced apart along the axial direction of the connecting shaft.

[0016] In this technical solution, by setting two first connecting plates and two second connecting plates in the connecting component, with the two first connecting plates spaced apart and the two second connecting plates spaced apart, the reliability of the connection can be improved.

[0017] Preferably, along the axial direction of the connecting shaft, the distance between the opposing surfaces of the two first connecting plates is equal to the distance between the opposing surfaces of the two second connecting plates, or the distance between the opposing surfaces of the two first connecting plates is equal to the distance between the opposing surfaces of the two second connecting plates.

[0018] In this technical solution, by setting the distance between the opposing surfaces of the two first connecting plates to be equal to the distance between the opposing surfaces of the two second connecting plates, or by setting the distance between the opposing surfaces of the two first connecting plates to be equal to the distance between the opposing surfaces of the two second connecting plates, the first connecting plates and the second connecting plates can abut against each other, making the connection more reliable.

[0019] Preferably, the folding plate includes a first folding plate and a second folding plate, the first folding plate and the second folding plate are respectively fixed on two adjacent foldable modules, and the two adjacent foldable modules are connected by two sets of coaxially arranged folding components. Along the axial direction of the rotating shaft, the two sets of folding components are spaced apart.

[0020] In each of the folding components, there are two first folding plates and two second folding plates. Along the axial direction of the rotating shaft, the two first folding plates are spaced apart, and the two second folding plates are spaced apart.

[0021] In this technical solution, by setting two first folding plates and two second folding plates in the folding assembly, with the two first folding plates spaced apart and the two second folding plates spaced apart, the reliability of folding can be improved.

[0022] Preferably, along the axial direction of the connecting shaft, the distance between the opposing surfaces of the two first folding plates is equal to the distance between the opposing surfaces of the two second folding plates, or the distance between the opposing surfaces of the two first folding plates is equal to the distance between the opposing surfaces of the two second folding plates.

[0023] In this technical solution, by setting the distance between the opposing surfaces of the two first folded plates to be equal to the distance between the opposing surfaces of the two second folded plates, or by setting the distance between the opposing surfaces of the two first folded plates to be equal to the distance between the opposing surfaces of the two second folded plates, the first folded plates and the second folded plates can abut against each other, making the connection more reliable.

[0024] Preferably, the folding plate is a rectangular plate, the width of the folding plate is the same as the thickness of the foldable module, and the extension direction of the folding plate is the same as the extension direction of the foldable module in which the folding plate is located.

[0025] Preferably, the size of the foldable module gradually decreases along the direction toward the lifting structure when the foldable gangway is fully extended.

[0026] Preferably, the number of foldable modules is three, and the three foldable modules are connected by two sets of folding components.

[0027] In this technical solution, by setting three foldable modules in the foldable gangway crane, the lifting distance of the foldable gangway crane can be increased.

[0028] A cruise ship comprising the foldable gangway as described above.

[0029] The positive and progressive effects of this invention are as follows: By incorporating at least two foldable modules within the foldable gangway crane, adjacent foldable modules are connected via folding components, and a lifting structure is provided on each foldable module. When the foldable gangway crane is needed for lifting the gangway, it can be unfolded for lifting; when not needed, it can be folded and stored. Furthermore, due to its foldable function, during the lifting process, the foldable gangway crane, carrying the gangway, moves outwards in a gradually unfolding state, resulting in a relatively small space occupation throughout the process.

[0050] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0051] like Figures 1-6 As shown, this embodiment provides a foldable gangway crane 100, which includes a folding assembly 1 and at least two foldable modules 3. Adjacent foldable modules 3 are connected by the folding assembly 1, and a lifting structure 4 is provided on the foldable modules 3. The folding assembly 1 includes a pivot 11 and multiple folding plates, which are respectively fixed to the ends of adjacent foldable modules 3. The folding plates have through holes, and the through holes on adjacent folding plates are aligned to form a connecting hole. The pivot 11 is disposed in the connecting hole. By providing at least two foldable modules 3 in the foldable gangway crane 100, connecting adjacent foldable modules 3 through the folding assembly 1, and providing a lifting structure 4 (specifically a hook) on the foldable modules 3, the foldable gangway crane 100 can be opened for lifting when needed, and folded away when not needed. Meanwhile, due to the foldable function of the foldable gangway crane 100, during the hoisting process, the foldable gangway crane 100 hoists the gangway and moves it outward, gradually opening up, and the space occupied throughout the process is relatively small.

[0052] Specifically, such as Figure 1 and Figure 3As shown, the foldable module 3 of the foldable gangway gantry 100 includes a first foldable module, a second foldable module, and two sets of coaxially arranged rotating connection assemblies 5. The first and second foldable modules are located at both ends of the foldable gangway gantry 100, and the lifting structure 4 is mounted on the first foldable module. The rotating connection assembly 5 is located at the end of the second foldable module away from the first foldable module, and the second foldable module can be rotatably connected to the bulkhead through the rotating connection assembly 5. By mounting the lifting structure 4 and the connection assembly 5 on the first and second foldable modules located at both ends of the foldable gangway gantry 100, respectively, the maximum lifting distance of the foldable gangway gantry 100 can be increased.

[0053] Of course, in other embodiments, when there are three or more foldable modules 3, the lifting structure 4 can also be set on the foldable module 3 located between the first and second foldable modules. In this case, the lifting distance achievable by the first foldable module at the end will be wasted. However, in more embodiments, the lifting structure 4 can be set on different foldable modules 3, which can adapt to the lifting requirements of more lifting distances and lifting paths, and will not be elaborated further here.

[0054] In this embodiment, as Figure 1 and Figure 3 As shown, the rotating connection assembly 5 includes a first connecting plate 51, a second connecting plate 52, and a connecting shaft 53. The first connecting plate 51 is fixed on the second foldable module, and the second connecting plate 52 is rotatably connected to the first connecting plate 51 through the connecting shaft 53. The second connecting plate 52 is used to fix itself to the bulkhead.

[0055] Among them, such as Figure 2 As shown, the first connecting plate 51 includes a first part and a second part, with an included angle α between the first part and the second part, the value of which is between 120° and 160°. The connecting assembly 5 also includes a third connecting plate 54, which connects the two second connecting plates 52 and is capable of contacting the bulkhead surface. By setting the first and second connecting parts to have an included angle, the foldable gangway 100 can be fixed to the bulkhead facing the cabin exit. By making the third connecting plate 54 contact the bulkhead surface, it is easier to fix the foldable gangway 100. The foldable gangway 100 can be fixed by using multiple bolts to pass through the third connecting plate 54 and achieve a threaded connection with the bulkhead.

[0056] Specifically, in this embodiment, α = 135°.

[0057] Of course, in other embodiments, α can also be set to other values ​​that allow the third connecting plate 54 to have a larger contact area with the bulkhead facing the cabin exit, which will not be elaborated here.

[0058] In this embodiment, there are two first connecting plates 51, which are spaced apart along the axial direction of the connecting shaft 53; there are also two second connecting plates 52, which are spaced apart along the axial direction of the connecting shaft 53. By providing two first connecting plates 51 and two second connecting plates 52 in the connecting assembly 5, with the two first connecting plates 51 spaced apart and the two second connecting plates 52 spaced apart, the reliability of the connection can be improved.

[0059] Simultaneously, along the axial direction of the connecting shaft 53, the distance between the opposing surfaces of the two first connecting plates 51 is equal to the distance between the opposing surfaces of the two second connecting plates 52. By setting the distance between the opposing surfaces of the two first connecting plates 51 to be equal to the distance between the opposing surfaces of the two second connecting plates 52, the first connecting plates 51 and the second connecting plates 52 can abut against each other, making the connection more reliable.

[0060] Of course, in other embodiments, the distance between the opposing surfaces of the two first connecting plates 51 can also be set to be equal to the distance between the opposing surfaces of the two second connecting plates 52, which will not be elaborated here.

[0061] In this embodiment, the folding plate includes a first folding plate 121 and a second folding plate 122. The first folding plate 121 and the second folding plate 122 are respectively fixed to two adjacent foldable modules 3. The folding plate fixed near the bulkhead in the same folding assembly 1 is defined as the first folding plate 121, and the folding plate fixed near the hoisting structure 4 in the same folding assembly 1 is defined as the second folding plate 122. Two adjacent foldable modules 3 are connected by two sets of coaxially arranged folding assemblies 1, spaced apart along the axial direction of the rotating shaft 11. Each folding assembly 1 contains two first folding plates 121 and two second folding plates 122, spaced apart along the axial direction of the rotating shaft 11. By providing two first folding plates 121 and two second folding plates 122 in the folding assembly 1, with the two first folding plates 121 and the two second folding plates 122 spaced apart, the reliability of the folding can be improved.

[0062] Specifically, along the axial direction of the connecting shaft 53, the distance between the opposing surfaces of the two first folding plates 121 is equal to the distance between the opposing surfaces of the two second folding plates 122. By setting the distance between the opposing surfaces of the two first folding plates 121 to be equal to the distance between the opposing surfaces of the two second folding plates 122, the first folding plates 121 and the second folding plates 122 can abut against each other, making the connection more reliable.

[0063] Of course, in other embodiments, the distance between the opposing surfaces of the two first folding plates 121 can also be set to be equal to the distance between the opposing surfaces of the two second folding plates 122, which will not be elaborated here.

[0064] In this embodiment, the folding plate is a rectangular plate, such as... Figure 2 As shown, the width of the folding plate is the same as the thickness D of the foldable module 3, and the extension direction of the folding plate is the same as the extension direction of the foldable module 3 to which the folding plate is located. That is to say, the extension direction of the folding plate is the same as the extension direction of the entire foldable gangway crane 100 when it is straightened.

[0065] In this embodiment, there are three foldable modules 3, which are connected by two sets of folding components 1. By providing three foldable modules 3 in the foldable gangway crane 100, the lifting distance of the foldable gangway crane 100 can be increased.

[0066] Of course, in other embodiments, the number of foldable modules 3 can also be two, that is, only the first foldable module and the second foldable module are set, which can realize the function of fixing to the bulkhead, folding and hoisting the gangway. In more embodiments, the number of foldable modules 3 can also be set to four, five or more, which can be determined according to the space of the cabin and the hoisting distance requirements, and will not be elaborated here.

[0067] In this embodiment, the foldable module 3 extends in the direction of the lifting structure 4 when the foldable gangway 100 is fully extended, and its size gradually decreases. For example... Figure 1 As shown, the dimensions mentioned here refer to the dimensions of the foldable gangway 100 in the height direction H. Since the lifting structure 4 is located at the end of the foldable gangway 100 furthest from the fixed side, that is, at the far end of the foldable gangway 100, for the same dimensions, the farther away from the fixed side, the greater the torque generated by the foldable module 3 on the fixed point. Therefore, the entire foldable gangway 100 is set to gradually decrease in size along the direction towards the lifting structure 4, that is, the farther away from the fixed point, the smaller the size of the foldable module 3, which can reduce the torque of the foldable gangway 100 on the fixed point and avoid damage.

[0068] Specifically, in this embodiment, as Figure 1 and Figure 3 As shown, the first foldable module is shaped like a "7", while the other foldable modules 3 are trapezoidal. Except for the first foldable module, the other foldable modules 3 are assembled into a trapezoidal shape. A reinforcing structure 6 is provided between the two parts of the first foldable module that form the "7" shape. This reinforcing structure 6 is approximately triangular.

[0069] This embodiment also provides a cruise ship equipped with the foldable gangway 100 described above. The foldable gangway 100 is fixed to the bulkhead directly opposite the cabin exit.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
