[0002] PCTC ships are roll-on / roll-off ships specially designed for the sea transport of cars and trucks. With its unique roll-on / roll-off method, this type of ship can efficiently load and unload vehicles without the need for lifting equipment, meeting the needs of large-scale vehicle transportation of automobile manufacturers, dealers and leasing companies. PCTC ships are not only widely used in various links of the automobile industry, such as transportation from the production site to the sales site, but also play an important role in global trade.

[0003] When encountering wind and waves or other severe weather conditions, a ship may take a natural reaction, which is to tilt to adapt to the sea conditions and maintain stability. This tilt is a strategy adopted by the ship to balance the impact of wind and waves and reduce bumps. When the wind and waves are strong, the ship may adjust the hull posture according to the direction and intensity of the wind and waves to form a certain angle with the waves, thereby reducing the direct impact of the waves on the hull and improving the stability and safety of the ship.

[0004] In actual use, when encountering wind and waves or other severe weather conditions, the PCTC ship may tilt in order to cope with the sea conditions and maintain stability. This tilt will cause a series of problems for vehicles and cargo on the internal deck, such as displacement, shaking and unstable center of gravity; vehicles may slide to one side or pile up due to gravity, bulk cargo may fall off from fixed positions, and the center of gravity of the hull may also shift, thereby exacerbating the instability of the ship.

[0025] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0027] The following is combined with Figure 1-5 This application is described in further detail.

[0028] The present application embodiment discloses a PCTC ship movable deck leveling device. Figure 1 , Figure 2A PCTC ship movable deck leveling device includes a support frame 1, a support deck 11 is arranged inside the support frame 1, one side of the support deck 11 is hinged to the support frame 1 through a rotating shaft 5, so that the support deck 11 can rotate inside the support frame 1. When the hull tilts, the angle of the support deck 11 inside the support frame 1 can be adjusted to adjust the support deck 11 to a horizontal state. The length direction of the support deck 11 is from the side where the support deck 11 is hinged to the support frame 1 to the side where the support deck 11 is opposite to the hinge.

[0029] A lifting assembly 2 is provided below the supporting deck 11, and the supporting deck 11 is connected to the lifting assembly 2 on the side thereof which is away from the hinged connection with the supporting frame 1. The supporting deck 11 is pushed by the lifting assembly 2 to be flipped around the hinged position of the supporting deck 11 and the supporting frame 1 as the axis.

[0030] The support frame 1 is a rectangular frame structure, and the support deck 11 is a rectangular plate body relatively adapted to the support frame 1. Anti-skid grooves 12 are arranged above the support deck 11, and the anti-skid grooves 12 significantly increase the friction between the deck and personnel and cargo by increasing the roughness of the deck surface.

[0031] Reference Figure 3 , Figure 4 A support plate 3 is disposed below the support deck 11. A plurality of support plates 3 are disposed below the support deck 11. The length direction of the support plate 3 is arranged along the length direction of the support deck 11. The plurality of support plates 3 are arranged equidistantly along the width direction of the support deck 11. The vertical section of the support plate 3 is an I-shaped structure, which improves the support capacity of the support plate 3.

[0032] Edge guards 31 are vertically arranged on both sides of the support deck 11 along the width direction, and the edge guards 31 are fixedly connected to the support deck 11, and are located at the gap between the support frame 1 and the support deck 11. The edge guards 31 ensure that there is no excessive gap between the deck and the support frame during the process of the deck being raised or lowered, which may not only affect the stability and flatness of the deck, but also become a safety hazard, such as pinching people or goods.

[0033] An auxiliary vertical plate 6 is vertically arranged at the position of the inner side wall of the support frame 1 relative to the edge guard plate 31. The auxiliary vertical plate 6 is fixedly connected to the support frame 1, and the auxiliary vertical plate 6 is arranged opposite to the edge guard plate 31. The auxiliary vertical plate 6 supports the edge guard plate 31 to descend vertically when the auxiliary vertical plate 6 corresponds to the edge guard plate 31 on both sides of the support frame.

[0034] Reference Figure 4 , Figure 5The lifting assembly 2 includes a hydraulic cylinder 21 located below the support deck 11. The position of the hydraulic cylinder 21 is fixed. The hydraulic cylinder 21 is arranged along the length direction of the support deck 11. Two hydraulic cylinders 21 are arranged opposite to each other, and the two hydraulic cylinders 21 are arranged in a horizontal direction. A connecting block 22 is fixedly connected to the hydraulic rod of the hydraulic cylinder 21. A synchronous bracket 4 is arranged between the two opposite connecting blocks 22. The cross-section of the synchronous bracket 4 is a cross-shaped structure. The synchronous bracket 4 includes a first synchronous plate and a second synchronous plate that are relatively vertically arranged. The first synchronous plate is arranged vertically, and the second synchronous plate is arranged horizontally. The first synchronous plate is fixedly connected to the second synchronous plate. The two ends of the synchronous bracket 4 are respectively fixedly connected to the hydraulic rods of the two hydraulic cylinders 21. The core function of the synchronous bracket 4 is to ensure that the two groups of connecting blocks 22 can maintain synchronization when performing relative movement. The cross-shaped design enables the bracket to provide stable support and synchronization effects in both horizontal and vertical directions.

[0035] A push rod 23 is hingedly provided on the connection block 22 , and the length direction of the push rod 23 is arranged along the width direction of the support deck 11 .

[0036] A lifting rod 24 is hingedly provided at one end of the hydraulic rod of the push rod 23 away from the hydraulic cylinder 21. A plurality of lifting rods 24 are provided along the direction of the push rod 23, and two opposite lifting rods 24 form a group. A plurality of groups are equidistantly provided along the length direction of the push rod 23. A lifting base 25 is hingedly provided at one end of the lifting rod 24 away from the push rod 23. The lifting base 25 is a rod body provided along the width direction of the support deck 11, and the lifting base 25 is fixedly connected to the support plate 3.

[0037] Through the extension and retraction of the hydraulic rod of the hydraulic cylinder 21, the hydraulic rod drives the push rod 23 to move in the horizontal direction through the connecting block 22, and the push rod 23 drives the lifting base 25 to flip through the lifting rod 24 hinged thereto, so that the lifting base 25 drives the support deck 11 to rotate along the hinge position between the support deck 11 and the support frame 1, thereby adjusting the angle between the support deck 11 and the support frame 1, so that the support deck 11 can always maintain a horizontal state.

[0038] When the PCTC ship movable deck leveling device is used, when the ship encounters wind and waves or other severe weather conditions that cause it to tilt, the hydraulic rod of the hydraulic cylinder 21 is controlled to extend and retract to drive the movement of the push rod 23 and the lifting rod 24. The movement of the push rod 23 and the lifting rod 24 will drive the position and angle of the support plate 3 to change, so that the support deck 11 rotates relative to the support frame 1. The synchronous bracket 4 ensures that the two groups of connecting blocks 22 can maintain synchronization during relative movement, ensuring the stability and accuracy of the adjustment of the support deck 11, and the auxiliary vertical plate 6 supports the vertical descent of the edge guard plate 31 on both sides of the support frame 1; through this adjustment, the displacement, shaking and unstable center of gravity of vehicles and cargo on the deck due to the tilt of the ship can be effectively reduced, thereby improving the stability and safety of the ship under severe weather conditions.
