Description

Technical Field

[0001] This invention belongs to the field of marine engineering technology, and specifically relates to a vehicle collision avoidance system for roll-on / roll-off ships. Background Technology

[0002] Ro-Ro ships are vessels specifically designed for transporting cars, trucks, trailers, and other vehicles. To prevent vehicles, especially large vehicles (such as trailers), from shifting and hitting the ship's bulkheads / structure or other vehicles due to loosening or failure of lashing caused by the ship's rolling motion, particularly during inclement weather, and to maintain the diversity of vehicles loaded on the deck of a Ro-Ro ship, it is essential to ensure that there are no obstructions on the deck space for loaded vehicles, allowing them free and unimpeded passage. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a vehicle anti-collision system for roll-on / roll-off ships, which can effectively prevent loaded vehicles from shifting during navigation and causing damage to the ship's structure or other vehicles, resulting in significant property losses.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A vehicle collision avoidance system for roll-on / roll-off ships is characterized by comprising a deck, a crash barrier, multiple lifting cylinders, and a crash avoidance system housing. A crash barrier receiving opening is provided on the deck, located at the end of the vehicle. The crash avoidance system housing is a hollow structure with an open upper surface, positioned directly below the crash barrier receiving opening, and its upper end is fixedly connected to the lower surface of the deck. Multiple crash barrier support plates are symmetrically fixed inside the crash avoidance system housing, perpendicular to the deck. A downwardly recessed crash barrier receiving groove is provided on the upper surface of each support plate. The crash barrier and the support plate are hinged together at 90° rotation. Multiple lifting cylinders are symmetrically spaced within the crash barrier receiving groove. The closed end of each lifting cylinder is hinged to the lower end of the inner wall of the crash avoidance system housing away from the hinged end of the crash barrier. The outer end of the cylinder shaft is hinged to the lower surface of the crash barrier.

[0006] Furthermore, the anti-collision system also includes a locking cylinder. Two first limiting support plates are symmetrically fixed at intervals on the inner side wall of the anti-collision system housing away from the hinge end of the anti-collision guardrail. Plate holes are opened on the first limiting support plates. The closed end of the locking cylinder and the outer end of the cylinder shaft are both connected to a short pipe through the locking cylinder eye plate. The short pipe passes through the plate hole and is slidably connected to the first limiting support plate. A locking pin is fixed at the end of the short pipe away from the locking cylinder. Two second limiting support plates are symmetrically arranged at intervals on the lower end surface of the anti-collision guardrail. Locking holes are provided at the lower part of the second limiting support plates. When the anti-collision guardrail is located in the anti-collision guardrail storage groove, the two second limiting support plates are located on both sides of the length direction of the locking cylinder. The locking pin extends into the locking hole under the push of the locking cylinder.

[0007] Furthermore, end plates are provided on both ends of the short tube along the central axis, and a fixing eye plate is fixed on the outer wall of the end plate near the locking cylinder. The locking cylinder eye plate and the fixing eye plate are fixedly connected by a pin.

[0008] Furthermore, a rotating hinge is provided on the side of the guardrail parallel to the guardrail support plate, and the rotating hinge is rotatably connected to the guardrail support plate through a pivot pin.

[0009] Furthermore, two cylinder eye plates are spaced apart on the lower inner wall of the anti-collision system storage box away from the hinged end of the anti-collision guardrail. The closed end of the lifting cylinder is hinged to the anti-collision system storage box through the cylinder eye plates. Two guardrail eye plates are fixedly arranged at intervals on the lower end surface of the anti-collision guardrail. The outer end of the cylinder shaft of the lifting cylinder is hinged to the anti-collision guardrail through the guardrail eye plates.

[0010] Furthermore, there are two lifting cylinders and two guardrail support plates. The two guardrail support plates are symmetrically spaced apart along the length of the guardrail receiving opening. The locking cylinder is located between the two guardrail support plates. Both lifting cylinders are located on the outside of the two guardrail support plates and are symmetrically arranged.

[0011] Furthermore, the crash barrier includes an outer side plate and an inner side plate arranged in parallel vertical directions, as well as a plurality of horizontal plates located between the outer side plate and the inner side plate. The height of the outer side plate is greater than the height of the inner side plate, and the height of the outer side plate is less than the width of the crash barrier receiving opening. The guardrail eye plate is fixedly located at the lower part of the inner side plate.

[0012] Furthermore, the width of the crash barrier support plate is the same as the width of the crash barrier system housing box. At the position opposite to the crash barrier housing opening and the crash barrier support plate, a groove extending outward from the lower end of the outer side plate of the housing is provided near the hinge side of the crash barrier and the crash barrier support plate.

[0013] Furthermore, the collision avoidance system also includes a control module and a power module. The control module includes a control valve group and a control box. The control module is a hydraulic pump station for the ship's passageway equipment. The hydraulic pump station is electrically connected to the control valve group. The control box is electrically connected to the control valve group. The control valve group is electrically connected to the locking cylinder and the lifting cylinder.

[0014] This invention relates to a vehicle collision avoidance system for roll-on / roll-off (Ro-Ro) ships. The collision guardrail is a closed structure welded from multiple steel plates, with strength equivalent to the deck. When stored, it allows normal vehicle passage and is considered part of the deck. In its stored state, the collision guardrail is supported by a support structure, transferring the vehicle's load. When a vehicle is loaded, the lifting cylinder is operated to raise the collision guardrail, which rotates around a hinge from a horizontal storage state to a vertical working state. This allows the collision guardrail to prevent vehicle displacement, thus providing a positioning function. When the collision guardrail reaches its vertical working state, it must be able to withstand vehicle impacts. Simply relying on the lifting cylinder for strength support is insufficient; a specially designed limiting support plate is required. This includes a first limiting support plate and a second limiting support plate. The first limiting support plate is welded to the ship's hull structure. The second limit support plate is used to support the locking cylinder; it is welded to the anti-collision structure. When the anti-collision structure is in the vertical working state, the locking hole on the second support plate faces downward. The locking cylinder is activated, and the locking pin extends and inserts into the locking hole. The support structure is used to withstand vehicle impacts and ensure that the anti-collision structure does not become unstable. It also protects the lifting cylinder. The anti-collision guardrail is opened and closed remotely by a control box located in the cargo compartment. Each flap can be opened individually or all flaps can be opened simultaneously. The control box can also indicate the opening status of the flap, and the system can be stopped via an emergency button in case of emergency. The power source for the crash barrier comes from the hydraulic pump station of the ship's roll-on / roll-off equipment, so there is no need to add an additional pump set, effectively saving installation costs. The valve block is equipped with an electromagnetic reversing valve, which can normally be controlled via the button in the control box. When the control box fails, the flap can also be operated in an emergency via the valve block. When the rear tires of the loaded vehicle hit the crash barrier, the vehicle will stop in time and be fixed and tied to restrict the vehicle's forward and backward displacement. This crash barrier structure has a certain strength to withstand the impact of vehicle collisions. When not in use, it can be stored below the deck, with its upper surface flush with the deck, as part of the deck, and can withstand the load during vehicle movement, enabling the versatility of loaded vehicles.
