Abstract
Description
Technical Field
[0001] This invention relates to the field of logistics and transportation technology, specifically to a vehicle ferry device for transporting large cargo across a river and its installation method. Background Technology
[0002] Car ferries are widely used in the Yangtze River basin of my country, specifically for transporting vehicles. They are equipped with propellers and rudders at both ends, and have wide, straight decks with slings and ramps. However, due to the large longitudinal slope of the ferry terminal and the insufficient length of the ramps, a large angle is created between the hull, the ramps, and the terminal slope, limiting passage. This is especially true for transporting heavy equipment, as large vehicles are often very long, and crossing the ramps at this angle can cause the axles to become suspended or even the ramps to bend, posing a high risk. Currently, most oversized cargo crossings across the river are carried out using a combination of road and water transport, which is inefficient and has high transportation costs. Summary of the Invention
[0003] To address the shortcomings of existing technologies, the present invention aims to provide a vehicle ferry crossing device for transporting large cargo and its installation method, which fills the large angle between the hull, the gangplank, and the slope of the ferry terminal, allowing large cargo vehicles to pass smoothly.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] A large-item transport ferry crossing device includes a frame support, a steel structure transport platform and a hydraulic lifting cylinder, wherein the steel structure transport platform and the frame support are hinged at one end.
[0006] The frame support includes a bottom steel structure panel and steel structure baffles on both sides, and the steel structure baffles on both sides and the bottom structural panel are welded together.
[0007] The hydraulic lifting cylinder includes an external support cylinder and an internal support cylinder. The external support cylinder is fixed to the steel structure baffle, and the internal support cylinder is fixed at the top of the steel structure panel away from the hinge end. The output end is movably connected to the steel structure transport platform.
[0008] Preferably, the steel structure conveying platform is located between the two steel structure baffles, and when the steel structure conveying platform is at its maximum tilt angle, the top surface of the steel structure conveying platform and the steel structure baffle are on the same plane.
[0009] Preferably, the steel structure conveying platform is located on the upper side of the steel structure baffles on both sides, and when the steel structure conveying platform is at its minimum tilt angle, the bottom of the steel structure conveying platform is located at the top of the steel structure baffles.
[0010] Preferably, the steel structure conveying platform and the hydraulic folding device are connected by a rotary bearing, and the hydraulic folding device is folded in two sections, with a built-in telescopic cylinder and two bearings controlling the rotation angle, which is 90-180°; the other end is provided with a triangular ladder, and the steel structure conveying platform and the triangular ladder are hinged together, and the triangular ladder has a flip angle of 0-180°.
[0011] Preferably, the steel structure conveying platform includes at least two long steel box girders, which are detachably connected to each other. One end of each long steel box girder is hinged to a bottom steel structure panel, and an internal support cylinder is connected to the bottom of each long steel box girder.
[0012] Preferably, the steel structure baffle is configured as a triangular structure, and reinforcing ribs are provided between the steel structure baffle and the bottom steel structure panel.
[0013] Preferably, both the external support cylinder and the internal support cylinder include a cylinder body and cylinder liner, a piston rod and a support panel, wherein the piston rod is mounted on the cylinder body and cylinder liner, and the end of the piston rod is fixed with a support panel.
[0014] Preferably, the bottom steel structure panel is provided with a power unit, which is connected to an external support cylinder and an internal support cylinder, and controls the external support cylinder and the internal support cylinder to drive.
[0015] A method for installing a ferry crossing device for transporting large cargo includes the following steps:
[0016] S1. River-crossing device transportation: The entire river-crossing device is transported using a semi-trailer truck;
[0017] S2. Installation of the river crossing device: The ferry docks and lowers the gangplank. The semi-trailer truck loads the river crossing device and transfers it to the installation position. When the front end of the bottom steel structure panel is aligned with the front section of the gangplank, the truck stops reversing and the external hydraulic cylinders begin to lift until the frame support base plate leaves the truck bed and the vehicle drives away.
[0018] S3. Adjustment of the river crossing device: The external hydraulic cylinder lowers the river crossing device to the bottom steel structure panel and lands on the ground. The internal hydraulic cylinder begins to lower, placing the other end of the steel structure transport platform on the ferry deck. Then, the triangular ladder at one end of the steel structure transport platform is manually flipped and placed on the slope and the ferry deck. The hydraulic folding device at the other end of the steel structure transport platform uses the hydraulic system of the entire device to flip the folding device so that its bottom fits against the wharf slope, reducing the angle between the steel structure platform and the wharf slope and forming an integrated transport plane.
[0019] S4, a freight truck used for transporting goods across the river.
[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0021] This heavy-duty transport ferry crossing device makes the angle formed by the ferry deck, gangplank, and dock slope gentler, allowing heavy-duty transport vehicles to smoothly complete the loading and unloading operations. It also has a built-in lifting function, and can be transferred using a semi-trailer flatbed truck. It can quickly enter or leave the site, improving the efficiency of relocation operations. This method of crossing the river greatly reduces the cost of crossing heavy-duty cargo. Attached Figure Description

[0035] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.
[0036] like Figure 1 and Figure 3 As shown, as a large-item transport ferry crossing device of the present invention, it is characterized by: including a frame support 1, a steel structure transport platform 2 and a hydraulic lifting cylinder 3, wherein the steel structure transport platform 2 and the frame support 1 are hinged at one end.
[0037] like Figure 4 As shown, the frame support 1 includes a bottom steel structure panel 11 and steel structure baffles 12 on both sides. The steel structure baffles 12 on both sides and the bottom structural panel 11 are welded together. The material is steel structure.
[0038] The hydraulic lifting cylinder 3 includes an external support cylinder 32 and an internal support cylinder 31. The external support cylinder 32 is fixed on the steel structure baffle 12, and the internal support cylinder 31 is fixed on the top of the steel structure panel 11 away from the hinge end. The output end is movably connected to the steel structure transport platform 2.
[0039] Specifically, the external support cylinder 32 is used to lift and lower the loading and transfer the river-crossing device to the ferry gangway position, while the internal support cylinder 31 adjusts the height of the steel structure conveying platform 2. By setting up two sets of support cylinders in different positions, the overall adjustment of the river-crossing device can be made more convenient and the usage effect can be better.
[0040] like Figure 1-4 As shown, when the steel structure conveying platform 2 is located between the two steel structure baffles 12, and the steel structure conveying platform 2 is at its maximum tilt angle, the top surface of the steel structure conveying platform 2 and the steel structure baffle 12 are on the same plane, which can protect both sides of the steel structure conveying platform 2. At the same time, it can enable the steel structure conveying platform 2 to withstand greater weight pressure.
[0041] When the steel structure conveyor platform 2 is located on the upper side of the steel structure baffles 12 on both sides, and the steel structure conveyor platform 2 is at its minimum tilt angle, the bottom of the steel structure conveyor platform 2 is located at the top of the steel structure baffles 12, which allows the steel structure conveyor platform 2 to have a larger adjustable tilt angle, making it suitable for environments with larger slopes and having a wider range of practical applications.
[0042] like Figure 4-5 As shown, the steel structure conveying platform 2 is equipped with a hydraulic folding device 7 at one end, which has a built-in telescopic cylinder. The hydraulic system of the entire device is used to flip the folding device 7 so that its bottom fits against the wharf slope, reducing the angle between the steel structure platform 2 and the wharf slope. During transfer, it is folded to fit against the gooseneck of the transport vehicle, shortening the overall transport length and facilitating transfer.
[0043] The other end of the steel structure conveying platform 2 is equipped with a triangular ladder 4. The steel structure conveying platform 2 and the triangular ladder 4 are hinged together, and the triangular ladder 4 has a flipping angle of 0-180°. It can be manually flipped to facilitate the transport vehicle to drive onto the steel structure conveying platform.
[0044] like Figure 4 As shown, the steel structure conveying platform 2 includes at least two long steel box beams 21, which are detachably connected. Each long steel box beam 21 is hinged to a bottom steel structure panel 11 at one end, and each long steel box beam 21 is connected to an internal support cylinder 31 at the bottom. The steel structure conveying platform 2 is formed by splicing multiple long steel box beams 21, and the width can be adjusted to a suitable value according to actual needs, resulting in better practical application. In addition, the setting of multiple long steel box beams 21 facilitates the handling operation of individual long steel box beams 21.
[0045] like Figure 1 As shown, the steel structure baffle 12 is set as a triangular structure, and there are reinforcing ribs between the steel structure baffle 12 and the bottom steel structure panel 11, which can make the position of the steel structure baffle 12 more stable and the actual application effect better.
[0046] like Figure 2 As shown, both the external support cylinder 32 and the internal support cylinder 31 include a cylinder body and cylinder liner 311, a piston rod 312 and a support panel 313. The piston rod 312 is mounted on the cylinder body and cylinder liner 311, and the support panel 313 is fixed to the end of the piston rod 312.
[0047] like Figure 4 As shown, a power unit 6 is provided on the bottom steel structure panel 11. The power unit 6 is connected to the external support cylinder 32 and the internal support cylinder 31, and controls the external support cylinder 32 and the internal support cylinder 31 to drive them.
[0048] When using, such as Figure 6As shown, the air ferry 15 docks and lowers the gangplank, and the semi-trailer 5 loads the river crossing device to the installation position. When the bottom steel structure panel 11 is aligned with the front end of the gangplank, the vehicle stops reversing, and the external support cylinder 32 begins to lift until the bottom steel structure panel 11 leaves the vehicle platform, and the vehicle drives out.
[0049] like Figure 8-9 As shown, the external support cylinder 32 lowers the river crossing device to the ground of the frame support 1, and the internal support cylinder 31 begins to descend, placing the other end of the bottom steel structure panel 11 onto the ferry deck. The hydraulic folding device 7 at one end of the steel structure transport platform 2 is flipped using the hydraulic system, so that its bottom fits against the wharf slope, reducing the angle between the steel structure transport platform 2 and the wharf. Then, the triangular ladder 4 at the contact end of the steel structure transport platform 2 and the ship plate is manually flipped down onto the slope and the ferry deck, making it easier for transport vehicles to drive onto the steel structure transport platform 2.
[0050] like Figure 7 As shown, the transport vehicle descends the slope from the dock, passes through the steel structure transport platform 2, and slowly drives onto the ferry deck. The transport vehicle then moves from the deck onto the ferry via the steel structure transport platform 2. During this process, as the weight of the ferry increases with the transport vehicle, the pressure on the water surface increases, which may cause the ship to sink. At this time, the internal support cylinder 31 can passively bear the force, and the piston rod 312 retracts, causing the steel structure transport platform 2 to descend, keeping the deck in constant contact with the steel structure transport platform 2 to ensure transport safety. Once the large transport vehicle has fully entered the ferry deck, the external support cylinder 32 lifts the entire river-crossing device, the transport vehicle is reversed for loading, the river-crossing device is transferred, the ferry deck is retracted, and loading is complete.
[0051] like Figure 10-11 As shown, by using this heavy-duty transport ferry crossing device, the angle formed by the ferry deck, gangplank, and dock ramp becomes gentler, allowing heavy-duty transport vehicles to smoothly complete loading and unloading operations. It also features a lifting function, enabling transfer using semi-trailer flatbed trucks, allowing for rapid entry and exit from the site and improving the efficiency of relocation operations. This method of crossing the river significantly reduces the cost of crossing heavy-duty cargo, and the passage width is much greater than that of tollbooth lanes, allowing even oversized cargo to cross the river in this way.
[0052] A method for installing a ferry crossing device for transporting large cargo includes the following steps:
[0053] S1. River crossing device transportation: The entire river crossing device will be transported using a semi-trailer truck.
[0054] S2. Placement of the river crossing device: The ferry docks and lowers the gangplank. The semi-trailer 5 loads the river crossing device and transfers it to the installation position. When the front end of the bottom steel structure panel 11 is aligned with the front section of the gangplank, the vehicle stops reversing and the external hydraulic cylinder 32 begins to lift until the bottom plate of the frame support 1 leaves the vehicle platform and the vehicle drives out.
[0055] S3. Adjustment of the river crossing device: The external hydraulic cylinder 32 lowers the river crossing device to the bottom steel structure panel and lands on the ground. The internal hydraulic cylinder 31 begins to lower, placing the other end of the steel structure transport platform 2 on the ferry deck. Then, the hydraulic folding device 7 at one end of the steel structure transport platform 2 is flipped using the hydraulic system so that its bottom fits against the wharf slope, reducing the angle between the steel structure transport platform 2 and the wharf. The triangular ladder 4 at the other end of the steel structure transport platform 2 is manually flipped and placed on the slope and the ferry deck.
[0056] S4, a freight truck used for transporting goods across the river.
[0057] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
