Description

Technical Field

[0001] This invention belongs to the field of boat transportation technology, and more specifically, relates to a boat transportation vehicle. This invention also relates to a boat transportation method. Background Technology

[0002] Unloading and recovering small boats, especially those with small boats, involves limitations such as the lack of dedicated sites, equipment, and vehicles, which increases the difficulty and risk of loading and unloading. Furthermore, during unloading on the shore and recovery to transport vehicles, factors such as shore slope, water flow velocity, and waves can prevent small boats from successfully completing the unloading and recovery operation. Therefore, an auxiliary device is needed for loading vehicles that can push the boat smoothly into the water during unloading and guide the bow section of the boat in advance during recovery.

[0003] Existing technology includes a device titled "A Fully Automated Rapid Cluster Deployment and Retrieval Platform for AUVs" (publication number 114506420A), which comprises a transmission system, an AUV conveyor, an AUV storage device, and a hoisting device. The transmission system is located at the bottom of the platform, the hoisting device is mounted at the top, and the AUV conveyor and storage device are installed inside the platform. The AUV conveyor is connected above the transmission system, and the AUV storage device is located above the conveyor. This invention modularizes and integrates the AUV cluster deployment and retrieval platform. The AUV conveyor uses gears to drive a conveyor belt in a rotary motion, facilitating the loading, deployment, and retrieval of AUVs by pausing at certain angles. The modular design allows for detachable support devices, enabling quick replacement of different AUVs for deployment and retrieval. The guide device employs a flexibly configurable modular design, allowing for AUV retrieval in different directions, and can also be arranged in an intermittent manner. However, this technology does not solve the technical problem of this application. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a boat transport vehicle with a simple structure that can provide the thrust required during the entry of the boat into the water and can also provide guidance to ensure accurate loading onto the transport vehicle when the boat is out of the water, thereby reducing the intensity of work and making it convenient and safe to use.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] This invention relates to a boat transport vehicle. The vehicle body has two parallel sliding tracks. A jacking device is located above and movably connected to the two sliding tracks. A winch is located at the front of the vehicle body. One end of the winch's connecting rope is connected to the head of the jacking device, and the other end of the connecting rope passes around a pulley located at the rear of the jacking device and is connected to the tail of the jacking device. The jacking device includes a moving platform and a tilting arm. One tilting arm is located on one side of the moving platform, and another tilting arm is located on the other side. When the winch winds up different ends of the connecting rope, the connecting rope is configured to move the moving platform relative to the sliding tracks on the vehicle body towards the front or rear of the vehicle body. The moving platform is connected to the tilting arm via a telescopic component. When the telescopic component extends or retracts, it is configured to tilt the tilting arm upwards or downwards relative to the moving platform.

[0007] The winch is a hydraulic winch, the telescopic component is a hydraulic cylinder, the connecting rope is a steel wire rope, and the winch and telescopic component are respectively connected to a hydraulic power source.

[0008] The moving platform of the jacking device is movably mounted in the track groove of the sliding track through the load-bearing wheels at the bottom, and a buffer pad is provided on the inner side of each tilting arm.

[0009] The lower part of the tilting arm is movably hinged to the connecting seat on the moving platform, one end of the telescopic component is movably hinged to the moving platform, and the other end of the telescopic component is movably hinged to the middle position of the tilting arm.

[0010] The hydraulic power source is connected to the winch via pipe I, and the hydraulic power is connected to the telescopic component via pipe II. Pipe I and pipe II are respectively connected to hydraulic valves, and the hydraulic valves are connected to the hydraulic power source.

[0011] The vessel transport vehicle is configured to switch between vessel unloading and vessel recovery states.

[0012] When the boat transport vehicle is operating in the boat unloading state, the vehicle body travels to the predetermined flood ramp. When the boat is in the stern floating state, the telescopic components are extended by controlling the extension of the telescopic components. The telescopic components control the tilting arm on the mobile platform to tilt upward and lift the bow of the boat. The winch is operated to pull the mobile platform to move to the rear of the vehicle body. The tilting arm acts on the front of the boat to push the boat backward in sync. As the draft of the bow of the boat increases, the boat is in a fully floating state. Due to inertia, the boat continues to move backward. At this time, the boat reversing function is activated simultaneously, so that the boat leaves the vehicle body and the boat unloading operation is completed.

[0013] When the boat transport vehicle is operating in the boat recovery state, the vehicle body travels to the designated recovery ramp, and the winch is used to pull the mobile platform to the rear of the vehicle body. The boat enters the loading range of the vehicle body, so that the stern area of ​​the boat is above the buffer pad of the tilting arm of the mobile platform. By controlling the extension of the telescopic component, the telescopic component controls the tilting arm on the mobile platform to tilt upward and lift the stern of the boat, so that the boat is in a stern floating state. The winch is then used to pull the mobile platform to the front of the vehicle body, and the buffer pad of the tilting arm applies force to pull the boat to the front of the vehicle body. When the boat reaches the designated position, the vehicle body slowly drives off the water along the ramp and lands on the vehicle body's load-bearing structure. When the vehicle body is transferred on land, the tilting arm is lowered to lower the center of gravity of the boat and ensure stability.

[0014] The present invention also relates to a simple method for transporting boats that provides the thrust required during the entry of the boat into the water and guides the boat to be accurately loaded onto a transport vehicle when it leaves the water, thereby reducing the workload and making it convenient and safe to use.

[0015] The aforementioned boat transportation method includes boat unloading method and boat recovery method;

[0016] The unloading steps of the boat unloading method are as follows: the vehicle body travels to the predetermined flood ramp. When the boat is in a stern floating state, the telescopic component is extended by controlling the telescopic component to control the tilting arm on the moving platform to tilt upward and lift the bow of the boat. The winch is operated to pull the moving platform to the rear of the vehicle body. The tilting arm acts on the front of the boat to push the boat backward in sync. As the draft of the bow of the boat increases, the boat is in a fully floating state. Due to inertia, the boat continues to move backward. At this time, the boat reversing function is activated simultaneously to make the boat leave the vehicle body, thus completing the boat unloading operation.

[0017] The recovery steps of the boat recovery method are as follows: The vehicle body travels to the predetermined recovery ramp, and the winch is operated to pull the mobile platform to the rear of the vehicle body. The boat enters the loading range of the vehicle body, so that the stern area of ​​the boat reaches the position above the buffer pad of the tilting arm of the mobile platform. By controlling the extension of the telescopic component, the telescopic component controls the tilting arm on the mobile platform to tilt upward and lift the stern of the boat, so that the boat is in a stern floating state. The winch is operated to pull the mobile platform to the front of the vehicle body, and the buffer pad of the tilting arm applies force to pull the boat to the front of the vehicle body. When the boat reaches the designated position, the vehicle body slowly drives away from the water surface along the ramp and lands on the load-bearing structure of the vehicle body. When the vehicle body is transferred on land, the tilting arm is lowered to lower the center of gravity of the boat and ensure stability.

[0018] The working principle and beneficial effects of the technical solution adopted in this invention are as follows:

[0019] The boat transport vehicle of this invention features an onboard device that allows for smooth jacking of the boat into the water during unloading and pre-guides the bow section of the boat during recovery, thereby improving convenience and safety during actual boat operations. The boat transport vehicle and method of this invention provide the necessary jacking force during boat entry and guide the boat to the transport vehicle accurately during retrieval, reducing workload.

[0025] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of the present invention, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:

[0026] As attached Figure 1 - Appendix Figure 3As shown, this invention relates to a boat transport vehicle. Two parallel sliding tracks 7 are installed on the vehicle body 11. A jacking device is located above and movably connected to the two sliding tracks 7. A winch 1 is arranged at the front of the vehicle body 11. One end of the connecting rope 2 of the winch 1 is connected to the head of the jacking device, and the other end of the connecting rope 2 passes around a pulley 4 located at the rear of the jacking device and is connected to the tail of the jacking device. The jacking device includes a moving platform 8 and a tilting arm 5. One tilting arm 5 is arranged on one side of the moving platform 8, and another tilting arm 5 is arranged on the other side. When the winch 1 winds up different ends of the connecting rope 2, the connecting rope 2 is configured to drive the moving platform 8 to move relative to the sliding tracks 7 on the vehicle body 11 towards the front or rear of the vehicle body 11. The moving platform 8 is connected to the tilting arm 5 via a telescopic component 3. When the telescopic component 5 extends or retracts, the telescopic component 3 is configured to drive the tilting arm 5 to tilt upwards or downwards relative to the moving platform 8. This invention addresses the shortcomings of existing technologies by proposing an improved technical solution. The vehicle of this invention is used in two states for boats: boat unloading and boat recovery. The device of this invention allows switching between these two states to meet different boat requirements. When the boat transport vehicle is operating in the boat unloading state, the vehicle body 11 travels to a predetermined ramp. When the boat 16 is in a stern-floating state, the telescopic component 3 extends, controlling the tilting arm 5 on the moving platform 8 to tilt upwards and lift the bow of the boat 16. The winch 1 pulls the moving platform 8 to the rear of the vehicle body 11, while the tilting arm 5 pushes the boat 16 backwards from its front. As the draft of the bow of the boat 16 increases, the boat 16 is in a fully floating state. Due to inertia, the boat 16 continues to move backwards. At this time, the boat 16's reversing function is activated, allowing the boat to leave the vehicle body 11, completing the boat unloading operation. When the boat transport vehicle is operating in the boat recovery state, the vehicle body 11 travels to the designated recovery ramp, and the winch 1 pulls the mobile platform 8 to move to the rear of the vehicle body 11. The boat 16 enters the loading range of the vehicle body 11, so that the stern area of ​​the boat 16 reaches the position above the buffer pad 6 of the tilting arm 5 of the mobile platform 8. By controlling the extension of the telescopic component 3, the telescopic component 3 controls the tilting arm 5 on the mobile platform 8 to tilt upward and lift the stern of the boat 16, so that the boat 16 is in a stern floating state. The winch 16 pulls the mobile platform 16 to move to the front of the vehicle body 11, and the buffer pad 6 of the tilting arm 5 applies force to pull the boat 16 to move to the front of the vehicle body 11. When the boat 16 reaches the designated position, the vehicle body 11 slowly drives away from the water along the ramp, so that 16 lands on the load-bearing structure of the vehicle body 11. When the vehicle body 11 is transferred on land, the tilting arm 5 is lowered to lower the center of gravity of the boat 16 and ensure stability. In this way, by installing a vehicle-mounted device on the vehicle body, the boat can be pushed smoothly into the water during unloading, and the bow section of the boat can be guided in advance during recovery, thereby improving the convenience and safety of the boat in actual operation.The boat transport vehicle of the present invention can provide the thrust required during the boat's entry into the water, and also provide guidance to ensure accurate loading onto the transport vehicle when the boat is out of the water, thereby reducing the intensity of the operation.

[0027] The winch 1 is a hydraulic winch, the telescopic component 3 is a hydraulic cylinder, and the connecting rope 2 is a steel wire rope. The winch 1 and the telescopic component 3 are respectively connected to a hydraulic power source 9. In this structure, the hydraulic power source provides hydraulic power to both the winch and the telescopic component, enabling the winch to release and retract the connecting rope during operation. The telescopic cylinder can extend and retract, driving the tilting arm to tilt.

[0028] The moving platform 8 of the jacking device is movably mounted in the track groove of the sliding track 7 via load-bearing wheels 12 at its bottom. Each tilting arm 5 has a buffer pad 6 installed on its inner side. This structure ensures that the moving platform moves along the sliding track and does not derail. The buffer pads are made of rubber and have a flexible structure, preventing damage to the vessel upon contact.

[0029] The lower part of the tilting arm 5 is hinged to the connecting seat 13 on the moving platform 8. One end of the telescopic component 3 is hinged to the moving platform 8, and the other end of the telescopic component 3 is hinged to the middle position of the tilting arm 5. With this structure, when the telescopic component extends or retracts, it causes the tilting arm to tilt in different directions relative to the moving platform, thus allowing it to move away from the boat or fit snugly against the side of the boat. In this way, when the moving platform moves, it can reliably apply force to the boat, driving the boat to move.

[0030] The hydraulic power source 9 is connected to the winch 1 via pipe I 14, and to the telescopic component 3 via pipe II 15. Pipes I 14 and II 15 are respectively connected to hydraulic valve 10, which in turn is connected to the hydraulic power source 9. With this structure, when the winch is working, it can drive different ends of the connecting rope to wind up, thus moving the mobile platform in different directions along the sliding track.

[0031] The aforementioned boat transport vehicle is configured to switch between boat unloading and boat recovery states. When the boat transport vehicle is operating in the boat unloading state, the vehicle body 11 travels to the predetermined flood ramp. When the boat 16 is in a stern-floating state, the telescopic component 3 is extended, and the telescopic component 3 controls the tilting arm 5 on the moving platform 8 to tilt upward and lift the bow of the boat 16. The winch 1 is operated to pull the moving platform 8 to the rear of the vehicle body 11, and the tilting arm 5 acts on the front of the boat 16 to push the boat 16 backward in sync. As the draft of the bow of the boat 16 increases, the boat 16 is in a fully floating state. Due to inertia, the boat 16 continues to move backward. At this time, the boat 16 reversing function is activated simultaneously, allowing the boat to leave the vehicle body 11, completing the unloading operation of the boat 16. When the boat transport vehicle is operating in the boat recovery state, the vehicle body 11 travels to the designated recovery ramp, and the winch 1 pulls the mobile platform 8 to the rear of the vehicle body 11. The boat 16 enters the loading range of the vehicle body 11, so that the stern area of ​​the boat 16 reaches the position above the buffer pad 6 of the tilting arm 5 of the mobile platform 8. By controlling the extension of the telescopic component 3, the telescopic component 3 controls the tilting arm 5 on the mobile platform 8 to tilt upward and lift the stern of the boat 16, so that the boat 16 is in a stern-floating state. The winch 16 pulls the mobile platform 16 to the front of the vehicle body 11, and the buffer pad 6 of the tilting arm 5 applies force to pull the boat 16 to the front of the vehicle body 11. When the boat 16 reaches the designated position, the vehicle body 11 slowly drives away from the water along the ramp, so that 16 lands on the load-bearing structure of the vehicle body 11. When the vehicle body 11 is transferred on land, the tilting arm 5 is lowered to lower the center of gravity of the boat 16 and ensure stability. In this way, the unloading and recovery of the boat can be reliably achieved with a high degree of automation.

[0032] The present invention also relates to a simple method for transporting boats that provides the thrust required during the entry of the boat into the water and guides the boat to be accurately loaded onto a transport vehicle when it leaves the water, thereby reducing the workload and making it convenient and safe to use.

[0033] The aforementioned boat transportation method includes boat unloading method and boat recovery method;

[0034] The unloading steps of the boat unloading method are as follows: The vehicle body 11 travels to the predetermined flood ramp. When the boat 16 is in a stern floating state, the telescopic component 3 is extended by controlling the telescopic component 3 to control the tilting arm 5 on the mobile platform 8 to tilt upward and lift the bow of the boat 16. The winch 1 is operated to pull the mobile platform 8 to move to the rear of the vehicle body 11. The tilting arm 5 acts on the front of the boat 16 to push the boat 16 backward in sync. As the draft of the bow of the boat 16 increases, the boat 16 is in a fully floating state. The boat 16 continues to move backward due to inertia. At this time, the boat 16 reverse function is activated simultaneously to make the boat leave the vehicle body 11, thus completing the unloading operation of the boat 16. The recovery steps of the boat recovery method are as follows: The vehicle body 11 travels to the predetermined recovery ramp, and the winch 1 pulls the mobile platform 8 to the rear of the vehicle body 11. The boat 16 enters the loading range of the vehicle body 11, so that the stern area of ​​the boat 16 reaches the position above the buffer pad 6 of the tilting arm 5 of the mobile platform 8. By controlling the extension of the telescopic component 3, the telescopic component 3 controls the tilting arm 5 on the mobile platform 8 to tilt upward and lift the stern of the boat 16, so that the boat 16 is in a stern floating state. The winch 16 pulls the mobile platform 16 to the front of the vehicle body 11, and the buffer pad 6 of the tilting arm 5 applies force to pull the boat 16 to the front of the vehicle body 11. When the boat 16 reaches the designated position, the vehicle body 11 slowly drives away from the water along the ramp, so that 16 lands on the load-bearing structure of the vehicle body 11. When the vehicle body 11 is transferred on land, the tilting arm 5 is lowered to lower the center of gravity of the boat 16 and ensure stability.
