Description

Technical Field

[0001] This utility model relates to the field of vehicle ferry technology, specifically a large vehicle ferry roll-on / roll-off loading vehicle. Background Technology

[0002] Large cargo transport vehicles serve as a vital support for economic development, not only meeting the transportation needs of construction materials for large-scale engineering projects but also ensuring the smooth implementation of key national projects. With "dual-use" as the core, efficient ferry solutions for large cargo transportation have been developed that are available at any time, can be moved at any time, and can be mobilized at any time, making them a backbone force in transportation support for "normal production, emergency response, and wartime combat".

[0003] Due to the limitations of existing bridges in transporting large items across the river, car ferries can serve as a relatively stable and safe mode of transportation. They can directly transport large items to suitable locations on the other side, avoiding the weight and width restrictions of bridges, reducing the risk of damage to goods and bridges, and ensuring the safety of transporting large items.

[0004] However, due to the long downhill slope at the ferry terminal, the ferry gangway, once lowered, forms a large angle with the slope. Large cargo transport vehicles are often long and have many axles, which can cause some axles to be suspended in the air during passage. The weight of the cargo can then crush the gangway, leading to accidents. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a large vehicle ferry roll-on / roll-off loading tool.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A large vehicle ferry roll-on / roll-off loading vehicle includes a crossbeam, one end of which is provided with a main folding flap, and the other end of which is hinged to a traveling beam. The end of the traveling beam away from the crossbeam is hinged to a secondary folding flap. A support frame conforming to the terrain of the ferry terminal is installed at the bottom of the traveling beam, and a support plate conforming to the deck surface of the ferry is installed at the bottom of the side of the crossbeam away from the traveling beam.

[0008] Preferably, a limiting cylinder for adjusting the angle between the crossbeam and the traveling beam is connected between the side of the crossbeam closest to the traveling beam and the support frame.

[0009] Preferably, the main folding flap is connected to the crossbeam via a first link and a second link. The first link and the second link are configured as two links with the same structure, one above the other, and are respectively hinged to the crossbeam and the main folding flap.

[0010] Preferably, a traction pin is installed at the bottom of the end of the main folding flap away from the crossbeam.

[0011] Preferably, the bottom of the traveling beam near the crossbeam is provided with traveling wheels that are raised and lowered by power supplied by a hydraulic power pump station.

[0012] Preferably, a first hydraulic cylinder for controlling the lifting and lowering of the main folding flap is connected between the crossbeam and the main folding flap, and a second hydraulic cylinder for controlling the lifting and lowering of the secondary folding flap is connected between the traveling beam and the secondary folding flap.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model uses a gentle bridge formed by a secondary folding flap, a traveling beam, a cross beam, and a main folding flap to fill the angle between the wharf's uphill and downhill slopes and the ferry's gangway, allowing oversized cargo transport vehicles to safely board and disembark. At the same time, the support plate is always in planar contact with the ferry's deck surface, resulting in a large stress-bearing area, protecting the ferry's deck surface, ensuring the safety of oversized trucks boarding and disembarking, and solving the problem of large transport vehicles weighing over 100 tons crossing rivers.

[0031] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0032] like Figure 1 As shown, this utility model discloses a large vehicle ferry roll-on / roll-off (Ro-Ro) vehicle, which includes a crossbeam 1, a traveling beam 2, a main folding flap 3, and a secondary folding flap 4. The crossbeam 1 is hinged to one end of the traveling beam 2, the main folding flap 3 is connected to the other end of the crossbeam 1, and the secondary folding flap 4 is hinged to the end of the traveling beam 2 away from the crossbeam 1. The secondary folding flap 4, the traveling beam 2, the crossbeam 1, and the main folding flap 3 form a gentle steel structure bridge, which allows large, extra-long, and extra-heavy vehicles to pass over it.

[0033] like Figure 2As shown, the bottom of the traveling beam 2 is equipped with traveling wheels 5 and support frame 6. The traveling wheels 5 are powered by a hydraulic power pump station to move up and down. The structure of the support frame 6 is adapted to the terrain of the ferry terminal 16, so that all parts of the traveling beam 2 are evenly supported. The traveling wheels 5 and support frame 6 are used for the transfer and erection of the work vehicle between the wharf shoreline and the ferry 15. The side of the cross beam 1 closest to the traveling beam 2 is connected to the support frame 6 with a limit cylinder 7. The angle between the cross beam 1 and the traveling beam 2 is controlled by the limit cylinder 7. During the transfer and erection process, the angle will be adjusted to make it smooth and improve the vehicle's passability. The bottom of the side of the cross beam 1 away from the traveling beam 2 is equipped with a support plate 8. The support plate 8 is in contact with the deck surface of the ferry 15. The support plate 8 and the deck surface of the ferry 15 are matched to distribute the load stress.

[0034] like Figure 1 As shown, the main folding flap 3 is connected to the crossbeam 1 via the first link 9 and the second link 10. The first link 9 and the second link 10 are two links with the same structure, one above the other. The first link 9 and the second link 10 are hinged to the crossbeam 1 and the main folding flap 3, respectively. A first hydraulic cylinder 11 is connected between the crossbeam 1 and the main folding flap 3. The first hydraulic cylinder 11 is used to control the lifting and lowering of the main folding flap 3. A second hydraulic cylinder 12 is connected between the traveling beam 2 and the auxiliary folding flap 4. The second hydraulic cylinder 12 is used to control the lifting and lowering of the auxiliary folding flap 4. The hydraulic system of the entire tooling vehicle is powered by a hydraulic power pump station. A traction pin 13 is installed at the bottom of the end of the main folding flap 3 away from the crossbeam 1. The traction pin 13 is hooked onto the traction seat of the traction vehicle 14, thereby cooperating with the traveling wheels 5 to realize the movement of the entire tooling.

[0035] The application steps for this tooling vehicle are as follows:

[0036] like Figure 3-5 As shown, the entire tooling vehicle is stationary on the ground. The first hydraulic cylinder 11 extends, and the main folding flap 3 slowly rises, so that the height of its bottom traction pin 13 is consistent with the height of the saddle of the tractor 14. At this time, the tractor 14 slowly reverses, so that its rear saddle engages with the traction pin 13. After completing the above steps, the first hydraulic cylinder 11 retracts, the main folding flap 3 lowers, and at the same time, the support plate 8 slowly lifts off the ground, and the traveling wheel 5 rises, so that the entire support frame 6 is lifted off the ground. At this time, the extension and retraction length of the limit cylinder 7 is adjusted so that the cross beam 1 and the traveling beam 2 form a suitable angle. After completing this step, the tooling vehicle is lifted off the ground by the tractor 14 and the traveling wheel 5, and is towed by the tractor 14, freely traveling on the road.

[0037] like Figure 6 As shown, the ferry 15 is docked at the ferry terminal 16, and the gangplank 17 is lowered. At this time, a large depression is formed between the three, as shown in the image. Figure 7As shown, the tractor 14 pulls the work vehicle toward the ferry 15. The tractor 14 is a three-axle vehicle with a small wheelbase, which can safely pass through the recessed area between the ferry terminal 16, the gangway 17 and the ferry 15.

[0038] like Figure 8 As shown, when the tractor 14 travels until the support plate 8 completely crosses the side of the ferry 15, the limit cylinder 7 is depressurized, and the height of the traveling wheel 5 decreases, so that the support frame 6 is in contact with the ground of the ferry terminal 16. The first cylinder 11 extends, the main folding flap 3 slowly tilts upward, and the support plate 8 slowly descends to be in contact with the deck surface of the ferry 15 until the traction pin 13 and the saddle of the tractor 14 are no longer under force. At this time, the retaining ring of the saddle is pulled out to disengage the traction pin 13 from the saddle, and the tractor 14 drives away from the bottom of the main folding flap 3. The first cylinder 11 retracts until the main folding flap 3 falls on the deck of the ferry 15 and is in contact with the deck surface. At the same time, the second cylinder 12 retracts until the auxiliary folding flap 4 falls on the ground of the ferry terminal 16 and is in contact with it.

[0039] like Figure 9 As shown, after completing the above steps, the secondary folding flap 4, the traveling beam 2, the cross beam 1 and the main folding flap 3 form a new channel. This channel fills the recessed area between the ferry terminal 16, the gangway 17 and the ferry boat 15, making it more level.

[0040] like Figure 10 As shown, oversized transport vehicles arrive from ferry terminal 16, travel over this auxiliary device, and can safely reach ferry 15. Figure 11 As shown, oversized transport vehicles can safely pass through the ferry terminal 16 by traveling on this work vehicle from the ferry 15. After the oversized transport vehicles have passed, this work vehicle can be lifted off the ground by the same steps as the work vehicle setup described above, supported by the tractor 14 and the traveling wheels 5, and can move freely on the road surface. It can then be towed by the tractor 14 to reverse away from the ferry 15 and head towards the shore.

[0041] It is simple to operate, convenient and efficient to use, and fills the huge depression between the car ferry 15, the gangway 17 and the car ferry terminal 16, so that large transport vehicles weighing more than 100 tons can pass smoothly via the car ferry.

[0042] The technical scope of this utility model 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 utility model, and all such modifications and variations should fall within the protection scope of this utility model.
