[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] This embodiment provides a connection device between an offshore platform module and a drilling vessel platform. Considering static, seismic, and typhoon conditions, the offshore platform module and the drilling vessel may sway under wave forces. Without measures to release this power, the connection between the trestle and the trestle will be damaged. Therefore, corresponding design measures are needed to ensure the trestle maintains its strength and lifespan under the influence of wind and wave forces on the offshore platform module and the drilling vessel platform. Figures 1-10As shown, the system includes a trestle frame 1, a trestle sliding device, and a sliding end mounting platform 2. Both the trestle frame 1 and the sliding end mounting platform 2 can be welded from channel steel, steel plates, and angle steel. The sliding end mounting platform 2 is mounted on the offshore platform module; in this embodiment, it is located on the top deck of the upper module of the offshore platform. One end of the trestle frame 1 is detachably connected to the drilling vessel platform, and the other end of the trestle frame 1 is mounted on the sliding end mounting platform 2. The trestle sliding device is located below the trestle frame 1 and contacts the upper surface of the sliding end mounting platform 2. Under the influence of wind and wave forces on the offshore platform module and the drilling vessel, the trestle sliding device can adaptably slide.

[0029] Optionally, the trestle sliding device includes a reinforcing housing 3 and multiple sliding members 4. The reinforcing housing 3 is located at the bottom of the trestle frame 1, and the multiple sliding members 4 are located on the lower surface of the reinforcing housing 3. The surface of each sliding member 4 that contacts the upper surface of the sliding end mounting platform 2 is an arc surface. The reinforcing housing 3 serves as the support for the trestle, ensuring the strength of the trestle in place. The arc surface facilitates the sliding of the sliding members 4, thereby facilitating the overall release of wind or wave impacts from the trestle. The arc surface is smooth and coated with grease.

[0030] Optionally, the reinforced housing 3 is rectangular, and the axis of the sliding member 4 is parallel to the width direction of the reinforced housing 3. This application does not specifically limit the number of sliding members 4. Optionally, the sliding member 4 is cylindrical.

[0031] Optionally, the reinforced housing 3 is provided with a reinforcement section at one end of the sliding end mounting platform 2. The reinforcement section includes fixed stiffeners 5 and reinforcing stiffeners 6. The fixed stiffeners 5 are located on both sides of the reinforced housing 3 along its length. Multiple reinforcing stiffeners 6 are distributed on the fixed stiffeners 5 along the length of the reinforced housing 3. The upper end of each reinforcing stiffener 6 is connected to the outer surface of the fixed stiffener 5, and the lower end of each reinforcing stiffener 6 extends beyond the bottom surface of the reinforced housing 3, contacting the upper surface of the sliding end mounting platform 2. The lower end of the reinforcing stiffener 6 may be rounded.

[0032] Optionally, the lower end of the reinforcing rib 6 is flush with the lower end of the sliding member 4.

[0033] Optionally, the end of the trestle frame 1 connected to the drilling vessel platform is provided with a connecting lug 7. The drilling vessel platform is provided with corresponding positioning posts 8, two of which are spaced apart. The connecting lug 7 extends between the two positioning posts 8. Both the connecting lug 7 and the positioning posts 8 have corresponding mounting holes. The connecting lug 7 and the positioning posts 8 are connected by a fixing sleeve 9, which passes through the mounting holes of both the positioning posts 8 and the connecting lug 7. Reinforcing ring plates 10 are provided on both sides of the fixing sleeve 9 extending beyond the positioning posts 8. The outer diameter of the reinforcing ring plate 10 is larger than the diameter of the mounting hole, and the reinforcing ring plate 10 is threadedly connected to the fixing sleeve 9. The connection structure of the positioning posts and the connecting lug is a common existing technology and will not be described in detail here. The detachable connection between the trestle frame 1 and the drilling vessel platform can also be achieved through the use of lugs and pins, depending on the actual on-site processing conditions.

[0034] Optionally, the sliding end erection platform 2 is provided with one or more horizontally inclined reinforcing beams 11 at one end for connecting the trestle frame 1.

[0035] The working process of this embodiment is as follows: the surface of the sliding part 4 is coated with grease, and the end of the trestle with the trestle sliding device is placed on the sliding end of the platform 2. The connecting lug 7 of the other end is connected to the positioning column 8 of the drilling ship platform through the fixing sleeve 9 and the reinforcing ring plate 10. When disassembling, the fixing sleeve 9 and the reinforcing ring plate 10 are removed, and the trestle can be retracted for easy disassembly and assembly at any time. The trestle can include a pedestrian trestle and a pipeline and cable trestle to ensure the passage of pipelines, cables and personnel.

[0036] In summary, in this embodiment, one end of the trestle frame is detachably connected to the drilling vessel platform, and the other end of the trestle frame is erected on the sliding end platform. The trestle frame contacts the upper surface of the sliding end platform through the trestle sliding device. Under the action of wind and wave forces on the offshore platform modules and the drilling vessel, the trestle sliding device can slide adaptively. By reserving a sliding area, the stability of the device is ensured. It has the characteristics of simple structure and good stability.
