Description

Technical Field

[0001] The present invention relates to the technical field of ships, and particularly to a multi-purpose ship. Background Art

[0002] A multi-purpose ship is a multi-purpose dry cargo ship that can carry general cargo, bulk cargo, containers, heavy lift cargo, and roll-on / roll-off cargo, and has characteristics such as diverse cargo loading. A multi-purpose ship can adapt to various shipping routes, carry various cargoes as efficiently as possible, and is easy to use. It is a ship type for carrying "uncertain" cargo. The structural characteristics of a multi-purpose ship include large cargo holds, regular cargo holds, and the cargo holds can be arranged in layers through the hatch covers on the second deck. The hatch cover system of a multi-purpose ship consists of an open weathertight hatch cover and a hatch cover on the second deck installed in the cargo hold. Generally, the open weathertight hatch cover can be designed to load containers or large cargo (such as port machinery, small ships, offshore wind turbine components, etc.) according to the requirements of the shipowner.

[0003] Since the cargo loaded generally has characteristics such as large size and heavy weight, a heavy lift is generally designed on one side of the ship's side for loading and unloading goods at the port. The loading of cargo in the cargo hold of this ship type is restricted by the cargo hold structure. Therefore, the loading in the cargo hold should maximize the utilization of the cargo hold capacity as much as possible, while loading irregular large cargo on the open deck requires ensuring the maximum utilization of the existing open area. In a conventional multi-purpose ship, the living quarters and the chimney are arranged on top of the engine room. The top of the living quarters is the cab, and there is a bridge structure extending from the side wall of the cab. The bridge structure will block part of the open deck area. The above arrangement will cause the loading of large cargo in the open area to be restricted by the bridge structure, unable to make good use of the open deck area, and the loading efficiency is low.

[0004] Therefore, a multi-purpose ship is needed to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a multi-purpose ship that can reduce the restriction of the bridge structure, thereby improving the cargo loading efficiency and making full use of the open deck area.

[0006] To achieve this purpose, the present invention adopts the following technical solutions:

[0007] A multi-purpose ship, comprising:

[0008] A hull having an open deck;

[0009] A crane provided on the open deck and located on one side of the hull;

[0010] A chimney fixedly provided on the open deck and located on the side of the hull where the crane is provided;

[0011] A living building, which is fixedly arranged on the open deck and is located at the bow of the hull.

[0012] A cab, which is arranged on the top of the living building.

[0013] A bridge assembly, including a fixed section and a retractable section. One end of the fixed section away from the retractable section is fixedly connected to the side wall of the cab, and the retractable section can be deployed or retracted relative to the fixed section.

[0014] In some embodiments, a hinge is arranged between the fixed section and the retractable section. One end of the hinge is connected to the fixed section, and the other end of the hinge is connected to the retractable section. The retractable section can be deployed or folded and retracted relative to the fixed section through the hinge.

[0015] In some embodiments, a plurality of the hinges are arranged at intervals between the fixed section and the retractable section.

[0016] In some embodiments, a support protrusion protrudes from one end of the fixed section towards the retractable section. When the retractable section is in a deployed state relative to the fixed section, the retractable section is supported on the support protrusion.

[0017] In some embodiments, a shock-absorbing pad is arranged at the upper end of the support protrusion.

[0018] In some embodiments, a reinforcing rib is arranged between the fixed section and the side wall of the cab, and the reinforcing rib is respectively connected to the side wall of the cab and the fixed section.

[0022] In some embodiments, a guardrail is arranged on the retractable section, and the guardrail can be erected or laid down relative to the retractable section.

[0023] The beneficial effects of the present invention:

[0024] A multi-purpose ship provided by the present invention has an open deck. A crane, a chimney and a living building are arranged on the open deck. The chimney and the crane are located on the same side of the open deck, so as to avoid occupying a large space due to scattered arrangement, and form a relatively large area for placing goods on the open deck. The living building is arranged at the bow of the ship hull, which can ensure that all crew members have a good operating view. A cab is arranged on the living building, and a bridge assembly is arranged on the side wall of the cab. The bridge assembly includes a fixed section and a retractable section. One end of the fixed section far from the retractable section is fixedly connected to the side wall of the cab, and the retractable section can be deployed or retracted relative to the fixed section. During the process of using the crane to load goods, the retractable section of the bridge assembly is first retracted. During the operation of the crane, interference between the crane and the retractable section can be avoided, so as to ensure the hoisting efficiency of the goods. Moreover, since the open deck directly below the retractable section is exposed, it is convenient to load goods in the area of the open deck corresponding to the retractable section, thereby further increasing the available area of the open deck.

[0032] Before explaining any embodiment of the present application in detail, it should be understood that the present application is not limited to the structural details and component arrangements described in the following description or shown in the above drawings.

[0033] In this application, the terms "comprising", "including", "having" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or apparatus comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or apparatus. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or apparatus comprising the element.

[0034] In this application, the terms "connected", "coupled", "joined", "mounted" can be direct connections, couplings, joins or mounts, or can be indirect connections, couplings, joins or mounts. By way of example, a direct connection means that two parts or components are connected together without an intermediate member being provided therebetween, and an indirect connection means that two parts or components are each connected to at least one intermediate member, and these two parts or components are connected through the intermediate member. In addition, "connected" and "coupled" are not limited to physical or mechanical connections or couplings, and can include electrical connections or couplings.

[0035] In this application, those of ordinary skill in the art will understand that the functions performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the functions performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0036] In this application, the orientation terms such as "upper", "lower", "left", "right", "front", "rear", etc. are described based on the orientation and positional relationship shown in the drawings, and should not be construed as a limitation on the embodiments of this application. In addition, in the context, it should also be understood that when it is mentioned that one element is connected "above" or "below" another element, it can not only be directly connected "above" or "below" another element, but also be indirectly connected "above" or "below" another element through an intermediate element. It should also be understood that the orientation terms such as the upper side, the lower side, the left side, the right side, the front side, the rear side, etc. not only represent the positive orientation, but can also be understood as the side orientation. For example, the lower side can include directly below, lower left, lower right, lower front, and lower rear, etc.

[0037] In the process of designing and manufacturing a multi-purpose ship, in order to be able to reduce the limitations of the bridge structure, thereby improving the loading efficiency of goods, and to be able to make full use of the open deck area, as Figures 1 - 4 shown, the present invention provides a multi-purpose ship. The multi-purpose ship includes a hull 1, a crane 2, a chimney 3, and a living building 4.

[0038] Among them, the hull 1 has an open deck 11. The crane 2 is arranged on the open deck 11 and is located on one side of the hull 1. The chimney 3 is fixedly arranged on the open deck 11 and is located on the side of the hull 1 where the crane 2 is provided. The living building 4 is fixedly arranged on the open deck 11 and is located at the bow of the hull 1. The cab 5 is arranged on the top of the living building 4. The bridge assembly 6 includes a fixed section 61 and a retractable section 62. One end of the fixed section 61 away from the retractable section 62 is fixedly connected to the side wall of the cab 5, and the retractable section 62 can be deployed or retracted relative to the fixed section 61.

[0039] During the process of enabling the crane 2 to load goods, first retract the retractable section 62 of the bridge assembly 6. During the operation of the crane 2, interference between the crane 2 and the retractable section 62 can be avoided, thus ensuring the lifting efficiency of the goods. Moreover, since the open deck 11 directly below the retractable section 62 is exposed, it is convenient to load goods in the area of the open deck 11 corresponding to the retractable section 62, thereby further increasing the available area of the open deck 11.

[0040] In some embodiments, a hinge is provided between the fixed section 61 and the retractable section 62. One end of the hinge is connected to the fixed section 61, and the other end of the hinge is connected to the retractable section 62. The retractable section 62 can be deployed or folded and retracted relative to the fixed section 61 through the hinge. By providing the hinge, the fixed section 61 and the retractable section 62 are rotatably connected, facilitating the deployment or retraction of the retractable section 62 relative to the fixed section 61. During this process, only the state of the retractable section 62 relative to the fixed section 61 needs to be adjusted, and there is no need to detach the retractable section 62 from the fixed section 61, thus ensuring the convenience of the deployment or recovery of the retractable section 62 relative to the fixed section 61. In other embodiments, a clamping structure can also be used to connect the fixed section 61 and the retractable section 62. When goods need to be stacked, the retractable section 62 can be removed and placed on the fixed section 61. After the goods are loaded, the retractable section 62 can be clamped and fixed to the fixed section 61.

[0041] In some embodiments, a plurality of hinges are arranged at intervals between the fixed section 61 and the retractable section 62. By providing a plurality of hinges, the connection stability between the fixed section 61 and the retractable section 62 can be improved, avoiding the single hinge being easily damaged.

[0042] In some embodiments, a support protrusion 63 protrudes from one end of the fixed section 61 facing the recovery section 62. When the recovery section 62 is in an unfolded state relative to the fixed section 61, the recovery section 62 is supported on the support protrusion 63. By providing the support protrusion 63, when the recovery section 62 is in an unfolded state relative to the fixed section 61, the recovery section 62 can be effectively supported and limited by the support protrusion 63, thus ensuring that the recovery section 62 is stably in the unfolded state. The support protrusion 63 can be an integral structure with the fixed section 61, thus ensuring the connection strength between the support protrusion 63 and the fixed section 61. In other embodiments, the support protrusion 63 can also be designed as a split structure with the fixed section 61, and the support protrusion 63 is snap-fitted or welded to the fixed section 61, and no further limitations are made here.

[0043] In some embodiments, a shock-absorbing pad is provided at the upper end of the support protrusion 63. By providing the shock-absorbing pad, it can play a buffering role during the process of the recovery section 62 unfolding relative to the fixed section 61, thus avoiding direct rigid collision between the recovery section 62 and the fixed section 61.

[0044] In some embodiments, a reinforcing rib 64 is provided between the fixed section 61 and the side wall of the cab 5, and the reinforcing rib 64 is connected to the side wall of the cab 5 and the fixed section 61 respectively. By providing the reinforcing rib 64, the connection strength between the fixed section 61 and the cab 5 can be improved, and the fixed section 61 can be effectively supported by the reinforcing rib 64.

[0045] In some embodiments, a lifting lug is fixedly provided on the recovery section 62. By providing the lifting lug, when the recovery section 62 needs to be retracted, the crane 2 acts on the lifting lug, so that the recovery section 62 can be effectively retracted under the traction of the crane 2. When the cargo loading and unloading is completed, the crane 2 and the lifting lug are used in cooperation to unfold the recovery section 62. To ensure the safety of the retraction and deployment of the recovery section 62, multiple lifting lugs are welded on the recovery section 62.

[0046] In some embodiments, the chimney 3 is arranged at the stern of the hull 1. By arranging the chimney 3 at the stern, the space at the stern can be fully utilized, and the chimney 3 and the crane 2 are on the same side, making full use of the space where large goods cannot be placed, so that the open deck 11 forms a more complete placement space, which is convenient for the stacking of large goods.

[0047] In some embodiments, multiple cranes 2 are arranged at intervals along the direction from the bow to the stern of the hull 1. By providing multiple cranes 2, the lifting efficiency can be further improved.

[0048] In some embodiments, a guardrail 621 is provided on the recovery section 62, and the guardrail 621 can be erected or laid down relative to the recovery section 62. When the crew needs to go up when the recovery section 62 is in the deployed state, the guardrail 621 is in the erected state. When the recovery section 62 needs to be retracted, the guardrail 621 needs to be laid down, and then the recovery section 62 is folded and retracted onto the fixed section 61.

[0049] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
