Description

Technical Field

[0001] This utility model belongs to the field of offshore pipeline connection platform operation technology. Specifically, this utility model is a platform support for offshore pipeline connection. Background Technology

[0002] The ocean contains a great deal of natural resources. When carrying out marine resource development, production operations or scientific research activities, an offshore platform is needed to provide the necessary offshore platform for production operations. At the same time, pipelines are installed on the offshore platform to transport materials.

[0003] A patent specification published on February 11, 2025, with patent number 202420836879.2, discloses a platform support for offshore pipeline connections, including a fixing part and an adjusting part. Two lugs are fixed to the bottom of the adjusting seat, and a connecting rod is fixed between the two lugs. The end of the connecting rod is rotatably connected to a support plate, and a worm wheel meshing with a worm gear is coaxially keyed at the center of the connecting rod. On one hand, the two clamping plates can clamp and fix the offshore platform pipeline. The base, adjusting seat, and side plates provide stable support and fixation for the clamping plates and pipeline, facilitating stable pipeline installation. On the other hand, rotating the worm gear drives the worm wheel to rotate, which in turn causes the adjusting seat to rotate. This design allows adjustment of the angle of the adjusting seat, which in turn adjusts the angle of the fixing part. By changing the angle of the fixing part, pipelines with different inclination angles can be installed. This design meets the installation requirements of pipelines with different inclination angles.

[0004] In existing technologies, due to the very large size of pipelines used in offshore platform operations, the installation of separate semi-ring structures is extremely inconvenient. Utility Model Content

[0008] The bracket is provided with a support plate on the side near the offshore platform, and the support plate is provided with a pin that passes through one end of the upper fixed arc.

[0009] The other end of the upper fixed arc is provided with a locking device that cooperates with the bracket.

[0010] The locking device includes a threaded shaft hinged to the top of the bracket and a threaded sleeve fitted onto the end of the threaded shaft, and the end of the upper fixing arc is provided with a clamping plate located between the bracket and the threaded sleeve.

[0011] A handwheel is provided at the end of the threaded sleeve away from the bracket.

[0012] The support system consists of a vertical frame fixed to the offshore platform, a horizontal frame with a support bracket on the side of the vertical frame, and a diagonal brace between the horizontal frame and the vertical frame.

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution, and to facilitate its implementation.

[0021] Please see Figure 1-3A platform support for offshore pipeline connection includes a support 1 installed on an offshore platform. The support 1 has a fixing structure for fixing the pipeline, which consists of a bracket 2 for supporting the pipeline and an upper fixing arc 3 that fastens to the top of the pipeline. When installing the pipeline on the offshore platform, the pipeline is placed on the bracket 2, and multiple sets of brackets 2 are evenly arranged along the edge of the offshore platform. The bracket 2 supports the pipeline, and the upper fixing arc 3 is used to fix the pipeline to the bracket 2. The pipeline can be clamped between the upper fixing arc 3 and the bracket 2, thereby achieving the purpose of fixing the pipeline on the offshore platform. The installation is simple and convenient for fixing pipelines on the offshore platform. In addition to supporting the bracket 2 and the pipeline, the support 1 also provides a platform for workers to stand on to fix the pipeline. The support 1 provides a standing platform for workers to operate and install the pipeline, which can prevent workers from falling and reduce accidents.

[0022] The bracket 2 is provided with an arc-shaped groove that connects to the upper fixed arc 3 to form a circle. The pipe is placed in the arc-shaped groove, which, together with the upper fixed arc 3, forms a circular structure that wraps around the outside of the pipe. This reduces the gap between the pipe and the upper fixed arc 3 and the bracket 2, thereby reducing the range of motion of the pipe after installation and lowering the risk of the equipment falling off due to excessive shaking.

[0023] The bracket 2 is provided with a support plate 4 on the side near the offshore platform. The support plate 4 is provided with a pin 5 that passes through one end of the upper fixed arc 3. The upper fixed arc 3 is hinged to the bracket 2 through the pin 5 and the support plate 4, so that the upper fixed arc 3 can be rotated open or rotated closed, which can complete the placement and fixation of the pipeline.

[0024] The other end of the upper fixed arc 3 is provided with a locking device that cooperates with the bracket 2; the upper fixed arc 3 and the bracket 2 are fixed together by the locking device, which is easy to operate. At the same time, after the pipe is installed, the upper fixed arc 3 and the bracket 2 are locked to prevent the pipe from pushing open the upper fixed arc 3 from the inside and causing the pipe to fall off.

[0025] The locking device includes a threaded shaft 6 hinged to the top of the bracket 2 and a threaded sleeve 7 fitted onto the end of the threaded shaft 6. The end of the upper fixing arc 3 is provided with a clamping plate located between the bracket 2 and the threaded sleeve 7. The upper fixing arc 3 is Ω-shaped. By rotating the threaded shaft 6, it is inserted into the end of the upper fixing arc 3. By tightening the threaded sleeve 7, the threaded sleeve 7 descends and presses against the end of the upper fixing arc 3, thereby achieving the purpose of fixing the upper fixing arc 3 onto the bracket 2. The overall operation is simple.

[0026] A handwheel 8 is provided at the end of the threaded sleeve 7 away from the bracket 2; this makes it convenient for staff to tighten the threaded sleeve 7.

[0027] The support frame 1 is divided into a vertical frame 11 fixed on the offshore platform, and a horizontal frame 12 supporting the support bracket 2 is provided on the side of the vertical frame 11. A diagonal brace 13 is provided between the horizontal frame 12 and the vertical frame 11. Through multiple steel frames connected at different angles, a support frame fixed on the offshore platform is formed, which ensures the strength of the support and reduces the risk of structural breakage under long-term use.

[0028] A connecting frame 14 is provided between the vertical frames 11, and a cover plate 15 is provided on the top of the horizontal frame 12. After the cover plate 15 is placed, the staff can stand on the cover plate 15 to work, providing the staff with a platform for standing and facilitating their work.

[0029] Working principle: First, open the upper fixing arc 3 so that it is unscrewed. Then, the worker places the pipe on the bracket 2, rotates the upper fixing arc 3 to cover the pipe, and then rotates the threaded shaft 6 so that the threaded shaft 6 is inserted into the inner side of the end of the upper fixing arc 3. The upper fixing arc 3 is made of two Ω-shaped iron frames welded together. There is a gap in the middle of the upper fixing arc 3. Insert the threaded shaft 6 into the gap inside the upper fixing arc 3. The gap width inside the upper fixing arc 3 should be smaller than the diameter of the threaded sleeve 7. By tightening the threaded sleeve 7, the upper fixing arc 3 can be fixed on the bracket 2, completing the installation of the entire pipe.

[0030] The technical effect of this utility model is as follows: When installing pipelines on an offshore platform, the pipelines are placed on brackets 2, and multiple sets of brackets 2 are evenly arranged along the edge of the offshore platform. The brackets 2 are used to support the pipelines, and the upper fixing arc 3 is used to fix the pipelines on the brackets 2, thereby achieving the purpose of fixing the pipelines on the offshore platform. Moreover, the installation is simple and convenient for installing and fixing pipelines on the offshore platform.

[0031] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
