Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering, and in particular to a multi-functional working vessel for dredging inland canal beds. Background Technology

[0002] Traditional inland canal dredging projects are often limited by narrow waterways (generally less than 50 meters wide). If multiple vessels are used in coordinated operations, there is not only a high risk of collision, but also great inconvenience in turning and moving the vessels, resulting in a decrease in process efficiency of up to 40%. At present, there are some self-propelled cutter suction dredgers that have shown good dredging efficiency in open waters, but their large hull size and limited functional integration make them difficult to adapt to the complex working conditions of narrow inland river sections. Other engineering vessels that use alternative fuels or are equipped with automatic control systems have improved energy efficiency, but still require multi-vehicle formations to complete the entire process from drilling and blasting to excavation and transportation. Utility Model Content

[0003] This utility model provides a multi-functional work vessel for dredging inland canals. Its purpose is to solve the problem of the need for a highly integrated and multifunctional work vessel suitable for narrow inland canals in existing water conservancy projects, thereby solving the problems of poor space matching and single function of the vessel.

[0004] To achieve the above objectives, embodiments of this utility model provide a multi-functional vessel for dredging inland canals, comprising: hull, A support assembly is located at the front middle of the hull, and the support assembly limits the hull to a designated position by telescopic movement. A drilling assembly is installed on one side of the hull along the bow-stern line, and the drilling assembly is used to drill holes in the riverbed; An excavation assembly, mounted on the bow, is used to excavate the riverbed after blasting. A transport assembly, positioned along the bow-stern line on the other side of the hull, is used to transport the excavated soil to the riverbank.

[0005] Preferably, a limiting groove is provided at the bow of the vessel, and the digging assembly is fixed in the limiting groove. The digging assembly includes a chassis, which is fixed in the limiting groove. A slewing mechanism is provided on the chassis, and a bucket assembly and a digging cab are provided on the slewing mechanism.

[0006] Preferably, the upper end of the support component is connected to the hull, and the lower end of the support component can extend and retract vertically to penetrate into the riverbed.

[0007] Preferably, a slide rail parallel to the bow and stern line is provided on one side of the bow and stern line of the hull, and each of the drilling assemblies is slidably disposed on the slide rail. The drilling assembly also includes a push-pull assembly for pushing each drilling assembly to a preset position on the slide rail and maintaining the current position.

[0008] Preferably, the drilling assembly is an underwater drilling rig.

[0009] Preferably, the transport component includes a floating structure consisting of several floats flexibly connected end to end, with one end of the floating structure close to the excavation component and the other end fixed to the riverbank. The floating structure is equipped with a soil hopper and a conveyor belt. The soil hopper is closer to the hull than the conveyor belt, and the conveyor belt is used to transport the soil that slides out of the soil hopper to the riverbank.

[0010] Preferably, the float is a foam with an outer metal shell.

[0011] The above-mentioned solution of this utility model has the following beneficial effects: First, in this application, the drilling and excavation components are integrated on the hull, giving the hull a composite function. It can drill into the riverbed to achieve blasting, and the excavation component excavates the soil generated by the blasting and transports the soil to the riverbank for collection and treatment via the transport component. Compared with conventional work vessels, this application does not require a large amount of soil to be piled up in the hull, reducing the requirements on the hull's load-bearing capacity.

[0012] Secondly, the support components can anchor the hull, preventing it from moving during operations. At the same time, the support components can also indicate the water depth of the current working area through preset scales.

[0013] Third, the transport components can move along with the ship to transport the excavated soil, reducing the frequency of the ship's return trip and improving operational efficiency.

[0014] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0017] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0018] like Figure 1 Paper Figure 5 As shown, this application provides a multi-functional vessel for dredging inland canals, including a hull 100 that can float on the water. A support assembly 200, a drilling assembly 300, and an excavation assembly 400 are respectively installed on the hull 100. The support assembly 200 is located at the front-middle section of the hull 100 and is retractable, allowing it to penetrate into the riverbed and confine the hull 100 to a designated position, preventing it from deviating from the work area due to water flow. The drilling assembly 300 is located along the bow-stern line on one side of the hull 100 and is used to drill holes in the riverbed to provide blasting holes for subsequent explosive installation, thereby enabling underwater blasting. The aforementioned excavation assembly 400 is located at the bow. When underwater blasting is completed, the excavation assembly 400 excavates the underwater soil and transports the excavated soil to the riverbank via a transport assembly 500. The transport component 500 is positioned along the bow-stern line on the other side of the hull 100. Understandably, the drilling component 300 and the transport component 500 are located on opposite sides of the bow-stern line, respectively.

[0019] In this application, by rationally arranging the support assembly 200, drilling assembly 300, and excavation assembly 400 on the hull 100, the hull 100 integrates multiple functions such as positioning, drilling, and excavation, reducing the number of vessels in inland canals and allowing for flexible scheduling of the work vessels. Simultaneously, the transport assembly 500 transports the excavated soil from the excavation assembly 400 to the riverbank in real time, preventing soil accumulation within the hull 100, reducing the number of times the work vessel needs to return, and improving operational efficiency.

[0020] Specifically, a limiting groove 110 is provided at the bow, and the excavation assembly 400 is fixed within the limiting groove 110. The excavation assembly 400 includes a chassis 410, which is fixed within the limiting groove 110. A slewing mechanism 420 is provided on the chassis 410, and a bucket assembly 430 and an excavation operator's cab are provided on the slewing mechanism 420.

[0021] In another embodiment of this application, the excavation component 400 is an excavator, and it is understood that the excavator satisfies the aforementioned limitations on the excavation component 400. The excavator can be moved into the limiting groove 110 by hoisting and fixed in the limiting groove 110 using existing methods, such as using a detachable abutment member installed in the limiting groove 110 to abut the excavator's tracks in the forward-backward direction (i.e., the bow-stern line direction) to prevent the excavator from moving forward or backward. For safety, abutment members can also be provided in the left-right direction (i.e., perpendicular to the bow-stern line direction).

[0022] The digging assembly 400 has a rotation function due to the slewing mechanism 420. Therefore, when the bucket assembly 430 is digging, it can expand the working range of the digging assembly 400 by rotating, and transfer the excavated soil to the transport assembly 500 by rotating.

[0023] Furthermore, the upper end of the aforementioned support component 200 is connected to the hull 100, and the lower end of the support component 200 can extend and retract vertically to penetrate into the riverbed. The support assembly 200 includes outriggers and an outrigger control assembly. The outriggers are controlled by the outrigger control assembly to extend, retract, or raise and lower. The outrigger control assembly can use a gear or rack structure to raise and lower the outriggers, or it can use a telescopic hydraulic cylinder to control the raising and lowering of the outriggers. In this application, the outriggers and outrigger lifting device disclosed in patent CN103161401A are used as the support assembly 200; alternatively, the liftable outrigger mechanism disclosed in patent CN104058340B can also be used. Since this part is prior art and has been maturely applied in underwater environments, it will not be described in detail here.

[0024] Preferably, the outriggers may also be provided with graduations.

[0025] A slide rail 120 is also provided on one side of the hull 100. The length direction of the slide rail 120 is parallel to the bow and stern lines of the hull 100. The aforementioned drilling assembly 300 is slidably mounted on the slide rail 120. Multiple drilling assemblies 300 are provided on the slide rail 120, and the spacing between the blast holes is adjusted by the different positions of the drilling assemblies 300 on the slide rail 120.

[0026] Preferably, two slide rails 120 are provided, and the two slide rails 120 are arranged in parallel. A slide block 310 is provided on both slide rails 120, and the drilling assembly 300 is installed on each slide block 310 in a corresponding manner, so as to facilitate the drilling assembly 300 to adjust the spacing of the blast holes along the length direction of the slide rail 120.

[0027] Preferably, a push-pull assembly is also provided on the slide rail 120 for pushing each drilling assembly 300 to a preset position and maintaining the preset position. The push-pull assembly includes a telescopic cylinder, which is disposed between the two slide rails 120. One end of the telescopic cylinder is fixed to the hull 100 by a hinge seat, and the other end is fixedly connected to the slide block 310 that fixes the drilling assembly 300 by another hinge seat. When the telescopic cylinder extends or retracts, it pushes or pulls the slide block 310 along the length direction of the slide rail 120, thereby adjusting the position of the slide block 310 on the slide rail 120.

[0028] Preferably, in this application, the drilling assembly 300 is an underwater drilling rig.

[0029] Based on existing underwater drilling rigs, they typically include a mast 321. A turntable 326 is fixedly connected to the upper middle part of the mast 321, and a rod clamp 325 is installed in the lower middle part. The turntable 326 is driven by a drill string 324. Driven by the turntable 326, the drill string 324 drills a hole. The rod clamp 325 works with the turntable 326 to keep the drill string 324 vertical. A pulley frame 322 is installed at the top of the mast 321. The pulley frame 322 includes at least one pulley, and a steel cable 323 is installed on the pulley. One end of the steel cable 323 is equipped with a connecting hook, and the other end is connected to a cable winding device for winding and unwinding the steel cable 323. The connecting hook is used to connect the drill rod, thereby increasing or decreasing the length of the drill string 324.

[0030] The aforementioned transport component 500 includes a floating structure comprising a plurality of floats 510 flexibly connected end to end, with one end of the floating structure close to the excavation component 400 and the other end fixed to the riverbank.

[0031] In this application, the floats 510 are flexibly connected, allowing relative displacement between adjacent floats 510 and ensuring that the floating structure can adaptively adjust its shape with horizontal movement. The flexible connection can be achieved using steel wire ropes, with both ends of the steel wire ropes connected to adjacent floats 510.

[0032] In this embodiment, the flexible connection is achieved using a connecting piece 511. Specifically, the connecting piece 511 has through holes at both ends, and the surface of the float 510 has a shaft that can be inserted into the through holes. The shaft rotates with the through holes, thereby enabling the floating structure to self-adjust. Preferably, the float 510 is rectangular, and several floats 510 are connected sequentially along the length of the float 510, with connecting pieces 511 connected to both ends of the width of each float 510.

[0033] The floating structure can be connected to the hull 100 through a flexible connection, ensuring that the floating structure can move together with the hull 100. The floating body 510 of the floating structure is close to the position of the excavation component 400 on the hull 100, and the other end of the floating structure is fixed to the riverbank.

[0034] The floating structure is also equipped with an earthwork hopper 520 and a conveyor belt 530. The earthwork hopper 520 is closer to the hull 100 than the conveyor belt 530. The conveyor belt 530 is used to transport the earthwork in the earthwork hopper 520 to the riverbank.

[0035] In this application, each float 510 is provided with a conveyor belt 530, and the ends of each conveyor belt 530 are adjacent to each other. The aforementioned earthmoving funnel 520 is fixed to the float 510 near the hull 100 by a bracket. The earthmoving funnel 520 is used to receive the earth excavated by the excavation component 400, wherein the conveyor belt 530 near the earthmoving funnel 520 is located at the lower end of the earthmoving funnel 520 to receive the earth that slides out of the earthmoving funnel 520 outlet.

[0036] Because there are gaps between the various floats 510 and between the conveyor belts 530, the soil may fall off during transportation due to excessive gaps in the conveyor belts 530. To address this, the length of the connecting piece 511 can be reduced to minimize soil falling. Of course, some soil falling off is unavoidable.

[0037] Preferably, the float 510 has a foam core and is wrapped with a metal shell.

[0038] The conveyor belt 530 on the floating structure is powered by the mains electricity from the shore, and the drive of the conveyor belt 530 can be achieved using existing technology. The drilling assembly 300 and the support assembly 200 on the hull 100 are powered by the hull 100's own power supply system. Based on the general setup of the hull 100, a cockpit can also be installed on the hull 100 to control the navigation of the hull 100.

[0039] In this application, by utilizing various existing components such as the excavation assembly 400, support assembly 200, and drilling assembly 300, the layout of the hull 100 is rearranged, enabling the hull 100 to integrate excavation, positioning, and drilling functions, thereby improving the integration level of the vessel and reducing the number of vessels traveling in the river. Secondly, a transport assembly 500 is designed to float on the water, facilitating the timely transport of excavated soil to the shore by the excavation assembly 400 during the excavation process. This reduces the load requirements of the hull 100 and the number of times the hull 100 needs to return to unload soil, thus improving efficiency. Furthermore, compared to existing technologies, the support assembly 200 in this application is used to fix the hull 100 in a designated position, preventing the hull 100 from moving with the water flow during the excavation process, rather than serving to support the hull 100.
