A support device for the bottom of a roll-on / roll-off ship ramp Technical Field

[0001] This utility model relates to the field of roll-on / roll-off equipment, and in particular to a support device for the bottom of a ramp of a roll-on / roll-off ship. Background Technology

[0002] Ro-Ro ships are like multi-story indoor parking garages, with multiple decks capable of accommodating a large number of vehicles at once. Vehicles enter and exit the ship via ramps. Currently, in operation, the ramps are typically supported only by the drive mechanism that rotates and raises them. The load of vehicles on the ramps is almost entirely borne by the drive mechanism, which, over time, can negatively impact the lifespan of the drive mechanism and the entire ramp system. Therefore, a support device needs to be designed to assist the drive mechanism in supporting the bottom of the ramp during operation, effectively protecting the drive mechanism and extending the overall lifespan of the ramp system. Utility Model Content

[0003] In view of the above-mentioned shortcomings, this utility model provides a bottom support device for roll-on / roll-off ship ramps, which can replace the final support of the drive unit in the working state of the ramp, effectively protect the drive unit, is safe and reliable, greatly improves the service life of the entire ramp equipment, and can adapt to the passage and storage of vehicles of different heights, making it highly applicable.

[0004] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0005] A support device for the bottom of a roll-on / roll-off (Ro-Ro) vessel ramp, wherein a connecting rod is hinged to the Ro-Ro vessel ramp, the support device includes a base, a telescopic rod, and a pin, both of which are fixed and located on one side of the base. The base has a locking hole, and one end of the connecting rod is slidably disposed inside the base. The telescopic rod extends out and drives the pin to insert into the base through the locking hole and press the connecting rod, thereby locking the connecting rod to the base.

[0006] According to one aspect of the present invention, it also includes a guide rail, which is fixed inside the base and has a track groove, and one end of the connecting rod is slidably disposed in the track groove.

[0007] According to one aspect of the present invention, the base includes a first fixing plate and a second fixing plate, which are arranged in parallel and spaced apart, and each of the two plates has a locking hole. One end of the connecting rod is slidably disposed between the first fixing plate and the second fixing plate.

[0008] According to one aspect of this utility model, a limiting plate is provided at one end of the guide rail, and the limiting plate is fixed inside the base.

[0009] According to one aspect of this utility model, the pin is in the shape of a rectangular block, the lock hole is a rectangular hole, and the track groove is a U-shaped groove.

[0010] According to one aspect of the present invention, the base further includes an auxiliary plate, which is arranged parallel to and spaced apart on one side of the first fixed plate. The auxiliary plate has an auxiliary hole, which is aligned with the lock hole, and the pin is sleeved in the auxiliary hole.

[0011] According to one aspect of the present invention, the base further includes a plurality of reinforcing ribs, which are respectively fixed to the first fixing plate, the second fixing plate, and the auxiliary plate.

[0012] According to one aspect of this utility model, the number of lock holes is several, the lock holes are arranged regularly on the base, and the number of telescopic rods, pins, and lock holes is the same.

[0013] According to one aspect of this utility model, it also includes a first limit switch and a second limit switch, both of which are disposed on one side of the base, and the first limit switch and the second limit switch are respectively disposed at both ends of the pin.

[0014] According to one aspect of the present invention, a control system is also included, which is connected to the telescopic rod, the first limit switch, and the second limit switch respectively.

[0015] The advantages of this invention are as follows: When the ramp (driven by the drive device) is raised, one end of the connecting rod slides to a suitable position within the base, then extends out through the telescopic rod. The drive pin inserts into the base through the locking hole and presses against the connecting rod, thereby locking the connecting rod to the base. At this time, the connecting rod assists the drive device in supporting the bottom of the ramp. Thus, this device can replace the original drive device in providing final support during ramp operation, effectively protecting the drive device, ensuring safety and reliability, and greatly extending the service life of the entire ramp equipment. By providing two or more locking holes, this device can ensure support for the ramp at different working angles, adapting to ramps with different working angles and accommodating vehicles of different heights for passage and storage, making it highly versatile.

[0025] Example 1

[0026] As shown in Figures 1-5, a support device for the bottom of a roll-on / roll-off (Ro-Ro) ship ramp is installed on the ground or any structural surface. A drive device 2 is located at the dock surface and connected to the bottom of the Ro-Ro ramp 1. A connecting rod 3 is hinged to the Ro-Ro ramp 1, with the drive device 2 located on the side of the ramp 1. The bottom end of the connecting rod 3 is slidably disposed within a base 4. The support device includes a base 4, a telescopic rod 5, and a pin 6. The base 4 is fixed to the ground. The telescopic rod 5 and the pin 6 are both located on the same side of the base 4. The telescopic rod 5 is an electric cylinder, and its extended end is fixed to the pin 6. The bottom of the telescopic rod 5 is fixed to the ground via a mounting base of any structure. A locking hole 7 is provided on the side of the base 4, with the pin 6 aligned directly opposite the locking hole 7. The extension of the telescopic rod 5 drives the pin 6 to insert into the base 4 through the locking hole 7 and press against the bottom end of the connecting rod 3, thereby locking the connecting rod 3 to the base 4.

[0027] In this embodiment, there is only one lock hole 7, which penetrates the side of the base 4. The number of telescopic rods 5, pins 6, and lock holes 7 are the same.

[0028] In this embodiment, the base 4 includes a first fixing plate 41 and a second fixing plate 42, which have the same structure and are arranged parallel to each other. They are fixed on the ground or the surface of any structural component, and the fixing method is arbitrary and can be welded. Lock holes 7 are respectively opened through the sides of the first fixing plate 41 and the second fixing plate 42. The bottom end of the connecting rod 3 is slidably disposed between the first fixing plate 41 and the second fixing plate 42.

[0029] In this embodiment, the base 4 also includes several stiffening plates 44. The stiffening plates 44 are of conventional structure, and are triangular or square plates. One end of the stiffening plate 44 is welded and fixed to the first fixing plate 41 or the second fixing plate 42, and the other end is fixed to the ground. In this way, the structural stability can be enhanced.

[0030] In this embodiment, the support device further includes a guide rail 8, which is fixed between the first fixing plate 41 and the second fixing plate 42. The guide rail 8 has a U-shaped groove 81, and the bottom end of the connecting rod 3 is slidably disposed in the groove 81. Thus, the bottom end of the connecting rod 3 can slide freely on the groove 81, and the guide rail 8, or the groove 81, can play a guiding and limiting role.

[0031] In this embodiment, a limiting plate 9 is provided at the end of the guide rail 8. The limiting plate 9 is inclined and fixed between the first fixing plate 41 and the second fixing plate 42. The limiting plate 9 can be welded to the two fixing plates or to the guide rail 8. In this way, the extreme position of the bottom end of the connecting rod 3 when sliding between the two fixing plates can be limited.

[0032] In this embodiment, the pin 6 is rectangular and the locking hole 7 is rectangular. The pin 6 and the locking hole 7 are structurally compatible. The bottom end of the connecting rod 3 is arc-shaped. The plate-shaped structure facilitates the rectangular pin 6 to better press against its end and facilitates the locking and fixing of the connecting rod 3 and the base 4. The arc-shaped structure facilitates the sliding of the bottom end of the connecting rod 3 on the track groove 81.

[0033] In this embodiment, a locking hole can also be provided at the bottom end of the connecting rod 3. The number and shape of the locking hole are adapted to the number and shape of the locking hole 7, and the two are used together. At this time, when the telescopic rod 5 drives the pin 6 to extend, it can drive the pin 6 to be inserted into the locking hole 7 and the locking hole in sequence, thereby locking the connecting rod 3 and the base 4 together, making the structure more stable. At this time, the bottom end of the connecting rod 3 can have any structural shape except for the arc-shaped structure at the bottom.

[0034] In practical applications, the roll-on / roll-off ship ramp 1 and drive device 2 are existing technologies and will not be described in detail.

[0035] The working principle of this embodiment is as follows: When the roll-on / roll-off ship needs to load and unload vehicles, the ramp 1 is driven by the drive device 2 and rotates and rises. At this time, the bottom end of the connecting rod 3 will slide on the track groove 81 in the base 4. After the bottom end of the connecting rod 3 slides to the appropriate position, it is extended by the telescopic rod 5. The drive pin 6 is inserted into the base 4 from the lock hole 7 and presses against the bottom end of the connecting rod 3, thereby locking the connecting rod 3 and the base 4. At this time, the connecting rod 3 can assist the drive device 2 in supporting the bottom of the ramp 1. At this time, vehicles can pass and be stored on the ramp 1.

[0036] The beneficial effects of this embodiment are as follows: This device can replace the original drive device 2 as the final support in the working state of the ramp 1, and can assist in supporting the ramp 1, thereby effectively protecting the drive device 2, ensuring safety and reliability, and greatly improving the service life of the entire ramp 1 equipment.

[0037] Example 2

[0038] The difference between this embodiment and implementation one is that the base 4 also includes an auxiliary plate 43. The auxiliary plate 43 is arranged parallel to and spaced on the side of the first fixed plate 41. The auxiliary plate 43 has auxiliary holes on its side. The auxiliary holes are aligned with the lock holes 7 and the number of the two is the same. The pin 6 is sleeved in the auxiliary holes.

[0039] In this embodiment, the auxiliary plate 43 is generally strip-shaped and can be consistent with the structural shape of the first fixing plate 41 or the second fixing plate 42.

[0040] In this embodiment, the auxiliary plate 43 and the first fixed plate 41 are connected and fixed by a square stiffener 44, and a triangular stiffener 44 is fixed on the side of the auxiliary plate 43; thus, the structure is more stable.

[0041] In this embodiment, when the pin 6 retracts from the lock hole 7 to release the connecting rod 3, the front end of the pin 6 retracts into the auxiliary hole, that is, the pin 6 does not completely exit the auxiliary plate 43. This can prevent the pin 6 from falling or tipping over (because the pin 6 or the lock hole 7 is at a certain height from the ground) and also reduce the burden on the telescopic rod 5.

[0042] The beneficial effects of this embodiment are as follows: by setting the auxiliary plate 43 and auxiliary holes, it is easy for the block pin 6 to stand up and avoid falling or tipping over, and it is easy to guide the extension and retraction of the pin 6. The structural design is more standardized and reasonable, and the structure is more stable.

[0043] Example 3

[0044] The difference between this embodiment and Embodiment 1 is that the support device also includes a first limit switch and a second limit switch, both of which are located on the side of the first fixing plate 41 of the base 4. The first limit switch and the second limit switch are respectively located at both ends of the pin 6.

[0045] In this embodiment, the support device also includes a control system, which is connected to the telescopic rod 5, the first limit switch, and the second limit switch respectively. This control system can be the main control system on the dock or in the control room of the roll-on / roll-off ship, used to control the actions of each power component.

[0046] In this embodiment, the telescopic rod 5 is extended by the control system, driving the pin 6 to insert into the lock hole 7 (or driving the pin 6 to insert into the lock hole 7 and the locking hole in sequence). After being inserted to a certain position, the second limit switch detects the position of the pin 6 and transmits the signal to the control system. The control system then controls the telescopic rod 5 to stop moving, thus completing the locking and fixing of the connecting rod 3 and the base 4. The telescopic rod 5 is retracted by the control system, driving the pin 6 to retract from the lock hole 7 (or driving the pin 6 to retract from the locking hole and the lock hole 7 in sequence). After retracting to a certain position, the first limit switch detects the position of the pin 6 and transmits the signal to the control system. The control system then controls the telescopic rod 5 to stop moving, thus completing the release of the connecting rod 3.

[0047] The beneficial effects of this embodiment are as follows: by setting the first limit switch and the second limit switch, this device can clearly and control when the pin 6 is fully inserted or fully withdrawn, which is more automated, more precise and flexible, and more convenient to use.

[0048] Example 4

[0049] As shown in Figures 1-5, the difference between this embodiment and Embodiment 1 is that this embodiment provides a multi-position support device for the bottom of a roll-on / roll-off ship ramp. A connecting rod 3 is hinged on the roll-on / roll-off ship ramp 1. The support device includes a base 4. The support device also includes a telescopic rod 5 and a pin 6, which are fixed together. There are at least two sets of both. The base 4 is provided with at least two locking holes 7. One end of the connecting rod 3 is slidably disposed in the base 4. When one end of the connecting rod 3 slides to any locking hole 7, the telescopic rod 5 extends, driving the pin 6 to insert into the base 4 from the locking hole 7 and press against and compress the connecting rod 3, thereby locking and fixing the connecting rod 3 to the base 4.

[0050] In this embodiment, the multi-station support device is installed on the ground or any structural surface. At the dock, a drive device 2 is connected to the bottom of the roll-on / roll-off (Ro-Ro) ship ramp 1. A connecting rod 3 is hinged to the Ro-Ro ship ramp 1, located on the side of the drive device 2, with the two devices positioned at the left and right ends of the ramp 1 respectively. The bottom end of the connecting rod 3 is slidably disposed within the base 4. The support device includes a base 4, a telescopic rod 5, and a pin 6. The base 4 is fixed to the ground. The telescopic rod 5 and the pin 6 are both located on the same side of the base 4. The telescopic rod 5 is an electric cylinder, with its extended end fixed to the pin 6. The bottom of the telescopic rod 5 is fixed to the ground via a mounting seat of any structure. Two locking holes 7 are provided on the side of the base 4, making this a dual-station support device. The locking holes 7 penetrate the side of the base 4. The telescopic rod 5, pin 6, and locking holes 7 are of equal number and their positions are appropriately matched, with their positions aligned directly opposite each other. When the bottom end of the connecting rod 3 slides to any of the locking holes 7, the telescopic rod 5 extends through that point, driving the pin 6 to insert into the base 4 from the locking hole 7 and press against the bottom end of the connecting rod 3, thereby locking the connecting rod 3 and the base 4 together. In this way, the device can ensure that the ramp 1 can be supported even when it is in two different working positions, ultimately enabling the passage and storage of vehicles of different heights, thus having a wider range of applications.

[0051] In this embodiment, the base 4 includes a first fixing plate 41 and a second fixing plate 42, which have the same structure and are arranged parallel to each other. They are fixed on the ground or any structural surface, and the fixing method is arbitrary and can be welded. Two locking holes 7 are respectively opened through the two ends of the sides of the first fixing plate 41 and the second fixing plate 42. The bottom end of the connecting rod 3 is slidably disposed between the first fixing plate 41 and the second fixing plate 42.

[0052] In this embodiment, the base 4 also includes several stiffening plates 44. The stiffening plates 44 are of conventional structure, and are triangular or square plates. One end of the stiffening plate 44 is welded and fixed to the first fixing plate 41 or the second fixing plate 42, and the other end is fixed to the ground. In this way, the structural stability can be enhanced.

[0053] In this embodiment, the support device further includes a guide rail 8, which is fixed between the first fixing plate 41 and the second fixing plate 42. The guide rail 8 has a U-shaped groove 81, and the bottom end of the connecting rod 3 is slidably disposed in the groove 81. Thus, the bottom end of the connecting rod 3 can slide freely on the groove 81, and the guide rail 8, or the groove 81, can play a guiding and limiting role.

[0054] In this embodiment, a limiting plate 9 is provided at the end of the guide rail 8. The limiting plate 9 is inclined and fixed between the first fixing plate 41 and the second fixing plate 42. The limiting plate 9 can be welded to the two fixing plates or to the guide rail 8. In this way, the extreme position of the bottom end of the connecting rod 3 when sliding between the two fixing plates can be limited.

[0055] In this embodiment, the pin 6 is rectangular and the locking hole 7 is rectangular. The pin 6 and the locking hole 7 are structurally compatible. The bottom end of the connecting rod 3 is arc-shaped. The plate-shaped structure facilitates the rectangular pin 6 to better press against its end and facilitates the locking and fixing of the connecting rod 3 and the base 4. The arc-shaped structure facilitates the sliding of the bottom end of the connecting rod 3 on the track groove 81.

[0056] In this embodiment, a locking hole can also be provided at the bottom end of the connecting rod 3. The number and shape of the locking hole are adapted to the number and shape of the locking hole 7, and the two are used together. At this time, when the telescopic rod 5 drives the pin 6 to extend, it can drive the pin 6 to be inserted into the locking hole 7 and the locking hole in sequence, thereby locking the connecting rod 3 and the base 4 together, making the structure more stable. At this time, the bottom end of the connecting rod 3 can have any structural shape except for the arc-shaped structure at the bottom.

[0057] In practical applications, this device can be expanded to meet the needs of different workstations. For example, it can be modified into a support device for three workstations, with three locking holes 7 on the base 4. This allows the support device to adapt to ramps 1 at different angles, satisfying multi-workstation requirements.

[0058] In practical applications, the roll-on / roll-off ship ramp 1 and drive device 2 are existing technologies and will not be described in detail.

[0059] The working principle of this embodiment is as follows: When the roll-on / roll-off ship needs to load and unload vehicles, the ramp 1 is driven by the drive device 2 and rotates and rises. At this time, the bottom end of the connecting rod 3 will slide on the track groove 81 in the base 4. After the bottom end of the connecting rod 3 slides to a certain locking hole 7, the corresponding telescopic rod 5 extends out and drives the pin 6 to insert into the base 4 from the locking hole 7 and press against the bottom end of the connecting rod 3, thereby locking the connecting rod 3 and the base 4. When the ramp 1 needs to be adjusted to different angles, it is only necessary to let the bottom end of the connecting rod 3 slide to the corresponding locking hole 7 and then perform the above-mentioned locking operation.

[0060] The beneficial effects of this embodiment are as follows: Through the design of multiple lock holes 7 or multiple workstations, the roll-on / roll-off equipment with this device can set several working angles of the ramp 1 according to the different height requirements of vehicle loading, allowing different vehicles to pass and be stored, so that the roll-on / roll-off ship can load more types of vehicles; that is, this device has stronger applicability and a wider range of applications.

[0061] The advantages of this utility model are as follows:

[0062] It can replace the original drive unit 2 as the final support in the working state of ramp 1, and can assist in supporting ramp 1, thereby effectively protecting drive unit 2, making it safe and reliable, and greatly improving the service life of the entire ramp 1 equipment.

[0063] It can ensure that the ramp 1 is supported when it is in a working position at different angles, that is, it can adapt to ramp 1 at different working angles and to the passage and storage of vehicles at different heights, and has strong applicability.

[0064] The overall structure is simple, easy to disassemble and manufacture, low in cost, and convenient and flexible to use.

[0065] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
