Description

Technical Field

[0001] This invention relates to the field of marine equipment technology, and specifically to a marine vehicle limit system. Background Technology

[0002] During roll-on / roll-off (Ro-Ro) shipping, cars are primarily secured to the deck using lashing straps at the front and rear. Because there's only one lashing point, the car is easily moved, collided, or even capsized by the ship's movement during transport. Therefore, a vehicle restraint system is urgently needed to solve the problem of vehicle displacement during transport. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a marine vehicle limiting system that restricts the movement of a vehicle during transport by limiting the front and rear tires on the vehicle deck, thereby ensuring transportation safety, reducing operating costs, and is simple to operate and economical.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A marine vehicle restraint system includes a vehicle deck, a front wheel restraint, and a rear wheel restraint. The front wheel restraint and the rear wheel restraint are both placed on the vehicle deck and are in close anti-slip contact with the vehicle deck. The contact surfaces of the front wheel restraint and the rear wheel restraint with the vehicle tires are curved. The front wheel restraint has a foldable structure, and the structures of the front wheel restraint and the rear wheel restraint may be the same or different.

[0005] Furthermore, the side plate in contact with the front wheel in the front wheel limiter is a flexible elastic side plate, and the bottom plate in contact with the vehicle deck in the front wheel limiter is a foldable bottom plate.

[0006] Furthermore, the front wheel limiter is a frame structure, including an L-shaped plate that flips down 180°, one end of the base plate is rotatably connected to the vertical plate of the L-shaped plate, and the upper and lower ends of the flexible elastic side plate are respectively connected to the free end of the horizontal plate of the L-shaped plate and the free end of the base plate.

[0007] Furthermore, the base plate includes at least two folded segments connected in sequence by rotation. The rotational connection structure between the base plate and the vertical plate of the L-shaped plate is a 0~90° rotation from the horizontal upward. Outward from the rotational connection structure, the rotation directions of two adjacent rotational connection structures are opposite, and the rotational connection structure between two adjacent folded segments is a 0~180° rotational structure. At the connection end of two adjacent folded segments, a limiting block and a limiting plate with an inner concave surface adapted to the outer contour surface of the limiting block are respectively provided. The inner concave surface of the limiting plate faces the limiting block.

[0008] Furthermore, the front wheel limiting structure also includes a foldable support assembly disposed inside its frame. When the foldable support assembly is unfolded, there are at least two support points distributed sequentially along the length of the base plate between its lower part and the inner wall of the innermost fold section. At the outermost support point, the foldable support assembly is rotatably connected to the base plate from 0 to 180°. The other support points are non-connection support points. There is at least one non-connection support point or rotatably connected support point between the foldable support assembly and the inner wall of the vertical plate of the L-shaped plate, as well as between the foldable support assembly and the flexible elastic side plate.

[0009] Furthermore, the support points between the foldable support assembly and the inner wall of the vertical plate of the L-shaped plate, as well as between the foldable support assembly and the flexible elastic side plate, are all non-connection support points.

[0010] Furthermore, the support assembly includes a first support rod, a second support rod, and a third support rod. One end of the second support rod and the third support rod are rotatably connected to the middle of the first support rod. When the foldable support assembly is unfolded, the other end of the second support rod abuts against the innermost folded section near the L-shaped plate, and the free end of the third support rod abuts against the inner side of the flexible elastic sidewall. One end of the first support rod is rotatably connected to the innermost folded inner side, and the other end abuts against the inner side of the vertical plate of the L-shaped plate. A pull rope is connected to the second support rod, and a rope hole is provided on the horizontal plate of the L-shaped plate. The other end of the pull rope passes through the rope hole.

[0011] Furthermore, the rear wheel limiter includes an inverted V-shaped housing, wherein the outer surface of the side arm in contact with the vehicle tire in the inverted V-shaped housing is a concave arc surface, and the thickness D of the contact end face of the two arms of the inverted V-shaped housing with the deck is ≥2d, where d is the arm thickness of the upper equal-thickness section of the side arm.

[0012] Furthermore, the lower part of the outer side of the side arm of the inverted V-shaped housing away from the car tire is an inclined surface that slopes toward the other side arm, with an angle α of 3~12° with the vertical direction, and the lower part of the inner side of the side arm is an inwardly concave arc surface.

[0013] Furthermore, the rear wheel limiter also includes a thrust plate disposed inside the housing. The thrust plate and the inner side of the arm in contact with the tire are connected upwardly via a hinge. The thrust plate is an arc-shaped piece. After it rotates upward, it fits tightly against the inner side of the arm on which it is located. When the rear wheel limiter is in use, the lower end face of the thrust plate abuts against the deck.

[0014] The marine vehicle limiting system of the present invention restricts the movement of the vehicle during transportation by limiting the front and rear tires of the vehicle on the vehicle deck, thereby ensuring transportation safety, reducing operating costs, and is simple to operate and economical.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1-6 As shown, a marine vehicle restraint system includes a vehicle deck 2, a front wheel restraint 6, and a rear wheel restraint 5. The front wheel restraint 6 and the rear wheel restraint 5 are both placed on the vehicle deck 2 and are in close anti-slip contact with the vehicle deck 2. The contact surfaces of the front wheel restraint 6 and the rear wheel restraint 5 with the vehicle tires are curved. The front wheel restraint 6 has a foldable structure, and the structures of the front wheel restraint 6 and the rear wheel restraint 5 may be the same or different.

[0024] Furthermore, the side plate in contact with the front wheel of the front wheel limiter 6 is a flexible elastic side plate, and the bottom plate in contact with the vehicle deck 2 of the front wheel limiter 6 is a foldable bottom plate. In some embodiments, the flexible elastic side plate is a plastic film 604.

[0025] Furthermore, the front wheel limiter 6 is a frame structure, including an L-shaped plate 603 that flips downward 180°. One end of the base plate is rotatably connected to the vertical plate of the L-shaped plate 603, and the upper and lower ends of the flexible elastic side plate are respectively connected to the free end of the horizontal plate of the L-shaped plate 603 and the free end of the base plate.

[0026] Furthermore, the base plate includes at least two folded segments connected in sequence by rotation. The rotational connection structure between the base plate and the vertical plate of the L-shaped plate 603 is a 0~90° rotation from the horizontal upward. Outward from the rotational connection structure, the rotational directions of two adjacent rotational connection structures are opposite, and the rotational connection structure between two adjacent folded segments is a 0~180° rotational structure. At the connection end of two adjacent folded segments, a limiting block and a limiting plate with an inner concave surface adapted to the outer contour surface of the limiting block are respectively provided. The inner concave surface of the limiting plate faces the limiting block.

[0027] In some embodiments, the base plate includes a first fold segment 601 and a second fold segment 602. One end of the first fold segment 601 is rotatably connected to the free end of the vertical plate of the L-shaped plate 603 via a hinge 605, and the other end of the first fold segment 601 is rotatably connected to one end of the second fold segment 602 via a hinge 605.

[0028] Furthermore, the front wheel limiting structure also includes a foldable support assembly disposed inside its frame. When the foldable support assembly is unfolded, there are at least two support points distributed sequentially along the length of the base plate between its lower part and the inner wall of the innermost fold section. At the outermost support point, the foldable support assembly is rotatably connected to the base plate from 0 to 180°. The other support points are non-connection support points. There is at least one non-connection support point or rotatably connected support point between the foldable support assembly and the inner wall of the vertical plate of the L-shaped plate 603 and between the foldable support assembly and the flexible elastic side plate.

[0029] Preferably, the support points between the foldable support assembly and the inner vertical wall of the L-shaped plate 603, as well as between the foldable support assembly and the flexible elastic side plate, are all non-connection support points.

[0030] In some embodiments, the support assembly includes a first support rod 609, a second support rod 610, and a third support rod 611. One end of the second support rod 610 and the third support rod 611 are rotatably connected to the middle of the first support rod 609. When the foldable support assembly is unfolded, the other end of the second support rod 610 abuts against the side of the innermost folded section near the L-shaped plate 603. The free end of the third support rod abuts against the inner side of the flexible elastic sidewall. One end of the first support rod is rotatably connected to the innermost folded inner side, and the other end abuts against the inner side of the vertical plate of the L-shaped plate 603.

[0031] A pull rope 608 is connected to the second support rod 609. A rope hole 606 is provided on the transverse plate of the L-shaped plate 603. The other end of the pull rope 608 passes through the rope hole 606 and is connected to a pull ring 607.

[0032] Furthermore, a stop ball 612 is connected to the pull rope located on the outside of the L-shaped plate.

[0033] A limiting block 615 is provided on the upper end surface of the first fold 601 near the second fold 602, and a limiting plate 613 with an inner concave surface that matches the outer contour surface of the limiting block 615 is provided on the upper end surface of the second fold 602 near the first fold 601, with the inner concave surface of the limiting plate 613 facing the first fold 601.

[0034] The front wheel limiter 6 is stored on the side rack. When in use, it is opened after removing and loosening the pull ring 607. The ball stop is located at the upper edge of the rope hole. The first support rod 609, the second support rod 610 and the third support rod 611, the first fold 601, the second fold 602 and the plastic film 604 are opened in sequence. The free end of the second support rod 610 rests on the side wall of the L-shaped plate 603. The free end of the third support rod 611 abuts against the upper surface of the second fold 602. The free end of the first support rod 609 is at an angle to the plastic film 604 but does not connect with it. The limiting block 615 abuts against the limiting plate 613 on the second fold 602.

[0035] Furthermore, the rear wheel limiter 5 includes an inverted V-shaped housing 501. The outer side of the side arm in the inverted V-shaped housing 501 that contacts the car tire is a concave arc surface. The thickness D of the contact end face of the two arms of the inverted V-shaped housing 501 with the deck 2 is ≥2d, where d is the arm thickness of the upper equal-thickness section of the side arm.

[0036] Furthermore, the lower part of the outer side of the side arm of the inverted V-shaped housing 501 away from the car tire is an inclined surface that slopes toward the other side arm, with an angle α of 3~12° with the vertical direction, and the lower part of the inner side of the side arm is a concave arc surface.

[0037] Furthermore, the rear wheel limiter 5 also includes a thrust plate 502 disposed inside the housing. The thrust plate 502 and the middle of the inner side of the arm that contacts the tire are rotatably connected upwards via a hinge 503. The thrust plate 502 is an arc-shaped piece. After it rotates upwards, it fits tightly against the inner side of the arm on which it is located. When the rear wheel limiter 5 is in use, the lower end face of the thrust plate 502 abuts against the deck.

[0038] The rear wheel limiter 5 is stacked and stored on the outside of the side walkway. When in use, it is taken out from top to bottom. After it is taken out, the thrust plate 502 automatically droops down and opens.

[0039] The method of using the vehicle limiting system described in this invention is as follows: Remove the front wheel limiter 6 and place it on the vehicle deck 2. After releasing the pull rope, the front wheel limiter 6 unfolds, with the plastic film 604 facing towards the front wheels of the parking space on the vehicle deck 2. When the vehicle stops, the front wheels gradually adhere to the plastic film 604, decelerating until it stops. The plastic film 604 deforms and adheres tightly to the front wheels. The force on the plastic film 604 is transmitted to the deck 2 through the support rod and the folded section. After the vehicle stops, engage the handbrake. After the driver gets out of the vehicle, remove the rear wheel limiter 5 from the side and unfold it, placing it at the rear wheels. Move the rear wheel limiter 5 to fit against the rear wheels, leaving a small gap.

[0040] Those skilled in the art should understand that the above description is merely a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
