Description

Technical Field

[0001] This invention belongs to the field of transport barge technology, specifically relating to a multi-functional cargo transport barge for marine engineering. Background Technology

[0002] Transport barges are large, flat-bottomed cargo ships without self-propulsion or equipped only with auxiliary power. They rely on tugboats for pushing or towing operations and are known for their simple structure, shallow draft, large load capacity, and low cost. They are widely used for the transshipment of bulk cargo, containers, and heavy equipment in inland waterways, coastal areas, and nearshore areas. Their open decks facilitate rapid loading and unloading and are adaptable to shallow waterways, making them a core tool for port cargo handling and short-distance water transport. As marine engineering expands into deep-sea areas, traditional barges have been upgraded to multi-functional cargo transport barges for marine engineering. These barges transport large jacket foundations, subsea pipelines, or complete modules and integrate dynamic positioning systems, ballast adjustment devices, and detachable roll-on / roll-off ramps, enabling precise berthing operations in conjunction with floating cranes. Some models even have pre-installed interfaces for wind turbine installation brackets or underwater robot deployment, allowing for flexible switching between transportation, warehousing, and construction operations, significantly reducing logistics costs and project time risks in complex sea conditions.

[0003] When loading cargo, existing barges are close to the shore or loading / unloading platform on one side. This often results in low efficiency of the loading and unloading equipment, which often has to rely on the loading and unloading drive equipment on the shore. Even if the barge has its own loading and unloading equipment, although it can improve the loading and unloading efficiency to some extent, the obstacles caused by its working range and the land it occupies will further affect the loading and unloading process and reduce the stacking area. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a multi-functional cargo transport barge for marine engineering.

[0005] The technical solution adopted to solve the above technical problems is: to provide a multi-functional cargo transport barge for marine engineering, including a barge body, a set of integrated shafts fixedly connected to both sides of the barge body, an extension plate mechanism rotatably connected to both sets of integrated shafts, and multiple extension support mechanisms fixedly connected to the bottom of both extension plate mechanisms. The barge body has two central partitions fixedly connected inside, and a support limiting mechanism is installed between the two sides of the two central partitions. A support driving mechanism is installed at the bottom of the inner wall of the barge body. The top of the barge body is equipped with a sealed deck, and multiple lifting devices are installed on the top of the barge body. Gear-sealed protective shells are fixedly connected to the outer walls on both sides of the barge body.

[0006] Furthermore, the extension plate mechanism includes multiple connecting rotating sleeves that are rotatably connected to multiple shafts in a set of integrated shafts. An extended folding arc plate is fixedly connected between one side of the multiple connecting rotating sleeves. Multiple plastic folding sealing sleeves are fixedly connected between the bottom of the extended folding arc plate and the side wall of the barge body. A continuous limiting guide rail is provided between the top of the barge body and the top of the extended folding arc plate.

[0007] The above technical solution allows the main body of the barge to extend to both sides via a rotating extension plate mechanism, providing more space for loading and unloading cargo, improving loading and unloading efficiency as well as the overall transportation efficiency of the barge.

[0008] Furthermore, the extension support mechanism includes a first arc-shaped support plate fixedly connected to the bottom of the extension plate mechanism, and a driven arc-shaped toothed plate is fixedly connected to the center of the inner wall of the first arc-shaped support plate.

[0009] With the above technical solution, when the extension support mechanism is driven to extend outward through the driven arc-shaped toothed plate, it will push the overall extension plate mechanism to unfold.

[0010] Furthermore, the center line of the arc of the first arc-shaped support plate and the central axis of the integrated shaft are on the same straight line.

[0011] With the above technical solution, since the first arc-shaped support plate and the extended folding arc plate are fixedly connected, the arc center line and the central axis are on the same straight line, which can ensure that the first arc-shaped support plate can rotate in the same way as the overall extension plate mechanism when it is driven.

[0012] Furthermore, the support limiting mechanism includes two hydraulic rods installed on one side of the two central partitions, a connecting rod fixedly connected between the bottom output ends of the two hydraulic rods, and multiple U-shaped limiting plates fixedly connected to the bottom of the connecting rod, with side strips fixedly connected to one side of each of the multiple U-shaped limiting plates.

[0013] With the above technical solution, when the extended folding arc plate is fully unfolded, the two hydraulic rods in the support and limiting mechanism drive the two connecting rods and multiple U-shaped limiting plates to descend, and in conjunction with the corresponding side clips, they engage with one end of multiple first arc-shaped support plates, thereby achieving support for the extended folding arc plate.

[0014] Furthermore, the support drive mechanism consists of two independent drive mechanisms, which are installed inside the barge body on both sides near the two extension plate mechanisms. Each independent drive mechanism includes multiple support shaft assemblies, and a connecting shaft is rotatably connected between the multiple support shaft assemblies. Multiple first transmission gears are fixedly connected to the connecting shaft, and a drive motor gear assembly is installed on one side of one of the first transmission gears at the bottom of the inner wall of the barge body.

[0015] With the above technical solution, when the extension plate mechanism is unfolded, the drive motor gear assembly drives the first transmission gear to rotate, and then drives multiple other first transmission gears to rotate through the connecting shaft. Finally, the driven arc-shaped toothed plate meshing with it drives the first arc-shaped support plate to rotate, thereby lifting the extension folding arc plate until the extension folding arc plate is fully unfolded. During the unfolding process, the plastic folding sealing sleeve is continuously stretched. When the extension folding arc plate is folded later, the plastic folding sealing sleeve will be compressed, achieving all-round protection for the first arc-shaped support plate. The extension plate mechanisms on both sides can be controlled independently through the independent drive mechanism, and can be unfolded and folded simultaneously.

[0016] Furthermore, the number of the plurality of support shaft assemblies is three, the number of the plurality of first transmission gears is four, and the three first transmission gears installed between the support shaft assemblies are all meshed with the corresponding driven arc-shaped toothed plates, and the gear in the drive motor gear assembly meshes with another first transmission gear.

[0017] The above technical solution ensures the stability of the transmission through multiple support shaft assemblies, and the additional first transmission gear meshes with the drive motor gear assembly for power transmission.

[0018] Furthermore, the support drive mechanism is a linkage drive mechanism, and the linkage drive mechanism is installed in the center inside the barge body. The linkage drive mechanism includes two drive sprocket assemblies and two sets of limit sprocket assemblies fixedly connected to the inner surface of the bottom of the barge body. A transmission chain is provided between the two drive sprocket assemblies and the two sets of limit sprocket assemblies. A drive motor assembly is installed on one side of the two drive sprocket assemblies. Elastic protective sleeves are provided on the outer walls of both ends of the two transmission chains. Auxiliary support shaft seats are installed on both sides inside the barge body. An extension shaft is provided between the two auxiliary support shaft seats and the corresponding limit sprocket assemblies. A second transmission gear is fixedly connected to each of the two extension shafts.

[0019] With the above technical solution, when the extension plate mechanism on one side is deployed, the support limiting mechanism on the other side is released from its limit. The two drive motor assemblies drive the drive sprocket assembly to rotate, which in turn drives the transmission chain to move, thereby pulling multiple limiting sprocket assemblies to rotate. The limiting sprocket assemblies at both ends drive the two extension shafts to rotate, which in turn drive the two second transmission gears to rotate. This enables the extension support mechanisms on both sides to extend and retract simultaneously, ultimately causing one side of the extension plate mechanism to unfold and the other side to retract. The support limiting mechanism on the unfolded side is then locked in place. This method is suitable for frequent cargo handling and allows for rapid loading and unloading on both loading and unloading platforms without the need for barge turning.

[0020] Furthermore, the two ends of the transmission chain are respectively installed between the two extended folding arc plates, and the two elastic protective sleeves are installed between the corresponding connecting rotating sleeve and the outer wall of the barge body to protect the transmission chain. The two ends of the two extended shafts are fixedly connected to the central shaft of the corresponding limiting sprocket assembly.

[0021] The above technical solution ensures that the two extended folding arc plates can quickly switch modes, which can improve the switching efficiency when transferring between two loading and unloading platforms at close range. At the same time, the elastic protective sleeve can prevent the transmission chain from being corroded by seawater.

[0022] The beneficial effects of the present invention are as follows: (1) By designing an extension plate mechanism and a support drive mechanism, the present invention allows the extension plate mechanism on one side to rotate, fold, and extend according to the selected docking side during hoisting operations, so that one side of the barge body is close to the shore or loading and unloading platform. Subsequently, multiple hoisting devices that move on the barge body and the extension plate mechanism can load and unload goods. The designed guide rails allow for free movement, effectively improving loading and unloading efficiency. The loading and unloading devices on the barge will not affect the loading and unloading process. (2) By designing an independent drive mechanism and a linkage drive mechanism, the present invention allows for independent operation of the extension plate mechanism. The extension plate mechanism on both sides can be expanded and folded at the same time. Simultaneous expansion can effectively increase the usable area and improve transportation efficiency. Through the linkage drive mechanism, the extension plate mechanism on one side expands and the other side retracts. The support limit mechanism on the expanded side is limited and locked. It is suitable for frequent handling of goods. It can achieve rapid loading and unloading on both loading and unloading platforms without barge turning. When transferring between two loading and unloading platforms at close distance, it can improve switching efficiency. (3) By designing plastic folding sealing sleeve and elastic protective sleeve, the first arc support plate and transmission chain can be protected respectively to avoid seawater corrosion.

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] Example 1: like Figures 1-7As shown in the figure, a multi-functional cargo transport barge for marine engineering in this embodiment includes a barge body 1. A set of integrated shafts 2 are fixedly connected to both sides of the barge body 1. An extension plate mechanism 3 is rotatably connected to each of the two sets of integrated shafts 2. The extension plate mechanism 3 includes multiple connecting rotating sleeves 301 that are rotatably connected to multiple shafts in the set of integrated shafts 2. An extension folding arc plate 302 is fixedly connected between one side of the multiple connecting rotating sleeves 301. Multiple plastic folding sealing sleeves 303 are fixedly connected between the bottom of the extension folding arc plate 302 and the side wall of the barge body 1. A continuous limiting guide rail is provided between the top of the barge body 1 and the top of the extension folding arc plate 302. By rotating the extension plate mechanism 3, the entire barge body 1 can be extended to both sides, providing more space for loading and unloading cargo, improving loading and unloading efficiency and the overall transportation efficiency of the barge.

[0027] like Figures 1-7 As shown, multiple extension support mechanisms 4 are fixedly connected to the bottom of both extension plate mechanisms 3. Each extension support mechanism 4 includes a first arc-shaped support plate 401 fixedly connected to the bottom of the extension plate mechanism 3. A driven arc-shaped toothed plate 402 is fixedly connected to the center of the inner wall of the first arc-shaped support plate 401. When the extension support mechanism 4 is extended outward through the driven arc-shaped toothed plate 402, it will push the entire extension plate mechanism 3 to unfold. The arc center line of the first arc-shaped support plate 401 and the central axis of the integrated shaft 2 are on the same straight line. Since the first arc-shaped support plate 401 and the extended folding arc plate 302 are fixedly connected, the fact that the arc center line and the central axis are on the same straight line can ensure that the first arc-shaped support plate 401 can rotate in the same way as the entire extension plate mechanism 3 when it is driven.

[0028] like Figures 1-7 As shown, the barge body 1 has two central partitions 5 fixedly connected inside. A support limiting mechanism 6 is installed between the two sides of the two central partitions 5. The support limiting mechanism 6 includes two hydraulic rods 601 installed on one side of the two central partitions 5. A connecting rod 602 is fixedly connected between the bottom output ends of the two hydraulic rods 601. Multiple U-shaped limiting plates 603 are fixedly connected to the bottom of the connecting rod 602. Side strips 604 are fixedly connected to one side of each of the multiple U-shaped limiting plates 603. When the extended folding arc plate 302 is fully unfolded, the two hydraulic rods 601 in the support limiting mechanism 6 drive the two connecting rods 602 and the multiple U-shaped limiting plates 603 to descend. In conjunction with the corresponding side strips 604, they engage with one end of multiple first arc-shaped support plates 401, thereby achieving support for the extended folding arc plate 302.

[0029] like Figures 1-7As shown, a support drive mechanism 7 is installed at the bottom of the inner wall of the barge body 1. The support drive mechanism 7 consists of two independent drive mechanisms 70, which are installed inside the barge body 1 on both sides near the two extension plate mechanisms 3. Each independent drive mechanism 70 includes multiple support shaft assemblies 701, which are rotatably connected by a connecting shaft 702. Multiple first transmission gears 703 are fixedly connected to the connecting shaft 702. One side of one of the first transmission gears 703 is equipped with a drive motor gear assembly 704 at the bottom of the inner wall of the barge body 1. When the extension plate mechanism 3 is unfolded, the drive motor gear assembly 704 drives the first transmission gear 703 to rotate, and then drives the other multiple first transmission gears 703 to rotate through the connecting shaft 702. Finally, the driven arc-shaped toothed plate 402 meshes with it, which drives the first arc-shaped support plate 401 to rotate, thereby lifting the extended folding arc plate 302 until the extended folding arc plate 302 is fully unfolded. During the unfolding process... The plastic folding sealing sleeve 303 will be continuously stretched. When the extended arc plate 302 is folded and extended, the plastic folding sealing sleeve 303 will be compressed, achieving all-round protection for the first arc support plate 401. The extension plate mechanism 3 on both sides can be controlled independently through the independent drive mechanism 70, and can be unfolded and folded and retracted at the same time. There are three support shaft seat assemblies 701 and four first transmission gears 703. The three first transmission gears 703 installed between the support shaft seat assemblies 701 are all meshed with the corresponding driven arc toothed plate 402. The gear in the drive motor gear assembly 704 meshes with another first transmission gear 703. The stability of the transmission is ensured by the multiple support shaft seat assemblies 701. The extra first transmission gear 703 meshes with the drive motor gear assembly 704 for power transmission. A sealed deck 8 is installed on the top of the barge body 1. Multiple hoisting devices 9 are installed on the top of the barge body 1. Gear sealing protective shells 10 are fixedly connected to the outer walls on both sides of the barge body 1.

[0030] Example 2: like Figures 1-12As shown, the difference from Embodiment 1 is that the support drive mechanism 7 is a linkage drive mechanism 71, and the linkage drive mechanism 71 is installed in the center inside the barge body 1. The linkage drive mechanism 71 includes two drive sprocket assemblies 711 and two sets of limiting sprocket assemblies 712 fixedly connected to the inner surface of the bottom of the barge body 1. A transmission chain 713 is provided between the two drive sprocket assemblies 711 and the two sets of limiting sprocket assemblies 712. A drive motor assembly 714 is installed on one side of the two drive sprocket assemblies 711, and the two ends of the two transmission chains 713 are connected to each other. The outer walls are all equipped with elastic protective sleeves 715. Auxiliary support shaft seats 716 are installed on both sides inside the barge body 1. Extension shafts 717 are provided between the corresponding limiting sprocket assemblies 712 on each of the two auxiliary support shaft seats 716. Second transmission gears 718 are fixedly connected to each of the two extension shafts 717. When the extension plate mechanism 3 on one side is deployed, the support limiting mechanism 6 on the other side is released from its limit. The two drive motor assemblies 714 drive the drive sprocket assembly 711 to rotate, which in turn drives the transmission chain 713 to move. The movement of the chain pulls multiple limit sprocket assemblies 712, causing them to rotate. The limit sprocket assemblies 712 at both ends drive the two extension shafts 717 to rotate, which in turn drives the two second transmission gears 718 to rotate. This causes the extension support mechanisms 4 on both sides to extend and retract simultaneously, ultimately causing one side of the extension plate mechanism 3 to unfold and the other side to retract. The support limit mechanism 6 on the unfolded side then locks in place. This design is suitable for frequent cargo handling, allowing for rapid loading and unloading on both loading and unloading platforms without the need for barge steering. The two transmission chains 713... The ends are respectively installed between the two extended folding arc plates 302, and the two elastic protective sleeves 715 are installed between the corresponding connecting rotating sleeve 301 and the outer wall of the barge body 1 to protect the transmission chain 713. The two ends of the two extended shafts 717 are fixedly connected to the central shaft of the corresponding limiting sprocket assembly 712 to ensure that the two extended folding arc plates 302 can quickly switch modes. When transmitting between the two loading and unloading platforms at close distance, the switching efficiency can be improved. At the same time, the elastic protective sleeves 715 can prevent the transmission chain 713 from being corroded by seawater.

[0031] The working principle of this embodiment is as follows: When carrying out hoisting work, depending on the side to be docked, the extension plate mechanism 3 on one side is driven to rotate, fold and extend through the support drive mechanism 7, so that one side of the barge body 1 is close to the shore or loading and unloading platform. Subsequently, the cargo is loaded and unloaded by multiple hoisting devices 9 that move on the barge body 1 and the extension plate mechanism 3. The design guide rail can be used to move freely. In Embodiment 1, when the extension plate mechanism 3 is unfolded, the drive motor gear assembly 704 drives the first transmission gear 703 to rotate, and then drives multiple other first transmission gears 703 to rotate via the connecting shaft 702. Finally, the driven arc-shaped toothed plate 402 meshes with it, driving the first arc-shaped support plate 401 to rotate, thereby lifting the extension folding arc plate 302 until the extension folding arc plate 302 is fully unfolded. At this time, the two hydraulic rods 601 in the support and limiting mechanism 6 drive the two connecting rods 602 and multiple U-shaped rods to rotate. The limiting plate 603 descends and, in conjunction with the corresponding side locking strip 604, engages with one end of multiple first arc-shaped support plates 401, thereby supporting the extended folding arc plate 302. During the unfolding process, the plastic folding sealing sleeve 303 is continuously stretched. When the extended folding arc plate 302 is folded later, the plastic folding sealing sleeve 303 is compressed, achieving all-round protection for the first arc-shaped support plate 401. The extension plate mechanisms 3 on both sides can be controlled independently through the independent drive mechanism 70, allowing for simultaneous unfolding and simultaneous folding and retraction. In Embodiment 2, when the extension plate mechanism 3 on one side is deployed, the support limiting mechanism 6 on the other side is released from its limit. The two drive motor assemblies 714 drive the drive sprocket assembly 711 to rotate, which in turn drives the transmission chain 713 to move, thereby pulling multiple limiting sprocket assemblies 712 to rotate. The limiting sprocket assemblies 712 at both ends drive the two extension shafts 717 to rotate, which in turn drives the two second transmission gears 718 to rotate, thereby driving the extension support mechanisms 4 on both sides to extend and retract simultaneously. Ultimately, the extension plate mechanism 3 on both sides is deployed on one side and retracted on the other side. The support limiting mechanism 6 on the deployed side is locked in place. This is suitable for frequent cargo handling and can achieve rapid loading and unloading on both loading and unloading platforms without the need for barge turning.

[0032] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
