Description

Technical Field

[0001] This utility model belongs to the field of offshore platform equipment, specifically relating to an auxiliary support for an offshore chain stop device. Background Technology

[0002] Offshore platforms are structures used for various activities in the ocean, mainly including oil and gas exploration and extraction, renewable energy development, scientific research, and other marine activities. The main types of offshore platforms include fixed platforms and floating platforms. Fixed platforms are constructed of steel or concrete and are fixed to the seabed, suitable for shallow water areas. Floating platforms use buoyancy to stay on the water surface and are suitable for deep water areas.

[0003] A marine chain stop device is a piece of equipment used on offshore platforms, ships, or other marine structures to prevent chains or ropes from slipping or losing tension under stress. This device has important applications in marine engineering, offshore oil and gas extraction, and offshore wind power. It is commonly used on floating platforms. However, due to seawater fluctuations, the device is prone to swaying. It is typically fixed to the platform by telescopic and adjustable outriggers. Because the outriggers are low and the telescopic length is large when encountering large waves, the bottom support of the marine chain stop device can easily impact the platform surface during return to its original position, causing damage to both the device and the platform surface.

The ball head is fixedly installed at the bottom of the connecting rod, and the ball groove is formed on the upper surface of the base. The ball head and the ball groove cooperate with each other.

[0009] In a preferred embodiment of the present invention, the limiting structure includes a limiting groove and two semi-circular arc seats. The limiting groove is formed on the top of the ball groove, and the two arc seats are installed in the limiting groove with their openings facing each other.

[0010] In a preferred embodiment of the present invention, a retaining ring is installed in the limiting groove at the top of the arc seat, and the retaining ring is engaged with the inner wall of the limiting groove.

[0011] In a preferred embodiment of the present invention, the lubrication structure includes a lubricating nozzle, which is installed in a through hole opened in the side wall of the base.

[0012] In a preferred embodiment of this utility model, the connecting rod is connected to the marine chain stop device via a mounting base fixedly installed at the bottom of the marine chain stop device, and the external thread on the outer side of the connecting rod engages with the internal thread of the central hole of the mounting base.

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0019] Please see Figures 1 to 3 The embodiments of this utility model include:

[0020] An auxiliary support for a marine chain stop device includes a support body, the support body including a connecting rod 3 and a base 4. The connecting rod 3 is connected to the marine chain stop device 1 by a mounting seat 2 fixedly installed at the bottom of the marine chain stop device 1. The external thread on the outer side of the connecting rod 3 is engaged with the internal thread of the center hole of the mounting seat 2, so that the auxiliary support is installed on the marine chain stop device 1.

[0021] The connecting rod 3 is connected to the base 4, and a follow-up rotating structure is provided between the connecting rod 3 and the base 4. This can prevent the bottom of the marine chain stop device 1 from colliding with the surface of the marine platform when encountering large waves, ensuring the safety of the marine chain stop device 1 and the marine platform, and reducing the number of maintenance times and costs.

[0022] The follow-up angle structure includes an adjustment structure for the connecting rod 3 to change angle, a limiting structure for connecting with the adjustment structure, and a lubrication structure to ensure smooth adjustment of the adjustment structure. The adjustment structure is located at the connection between the connecting rod 3 and the base 4, and the limiting structure and the lubrication structure are both located on the base 4.

[0023] The adjustment structure includes a ball head 5 and a ball groove 6. The ball head 5 is fixedly installed at the bottom of the connecting rod 3. The ball groove 6 is formed on the upper surface of the base 4. The ball head 5 cooperates with the ball groove 6. The ball head 5 rotates in the ball groove 6 to adapt to the upper surface of the offshore platform. When the bottom surface of the base 4 contacts the upper surface of the offshore platform, the angle can be quickly adjusted so that the bottom surface of the base 4 can quickly and completely adhere to the upper surface of the offshore platform.

[0024] The limiting structure includes a limiting groove 7 and two semi-circular arc seats 8. The limiting groove 7 is opened on the top of the ball groove 6, and the two arc seats 8 are installed in the limiting groove 7 with their openings facing each other. The arc seats 8 are used to limit the ball head 5 and prevent it from leaving the ball groove 6.

[0025] The semi-circular arc seat 8 design helps absorb vibrations, reduce impact forces in the mechanical system, and protect the integrity of the structure.

[0026] A retaining ring 9 is installed in the limiting groove 7 at the top of the arc seat 8. The retaining ring 9 is inserted into the inner wall of the limiting groove 7 and is used to limit the arc seat 8 to prevent it from falling out of the ball groove 6.

[0027] The lubrication structure includes a lubricating nozzle 10, which is installed in a through hole 11 on the side wall of the base 4. The lubricating nozzle 10 lubricates the ball head 5 through the through hole 11, reducing the friction between the ball head 5 and the ball groove 6 during rotation, making its rotation smoother.

[0028] Unlike existing technologies, this utility model provides an auxiliary support for a marine chain stop device. This auxiliary support has a follow-up rotation structure, which can prevent the bottom of the marine chain stop device from colliding with the surface of the offshore platform when encountering large waves, ensuring the safety of the marine chain stop device and the offshore platform, and reducing the number of maintenance times and costs.
