Description

Technical Field

[0001] This utility model belongs to the field of oil drilling and production technology, and specifically relates to a device for fixing oil pipelines on offshore platforms. Background Technology

[0002] Offshore oil exploration and development operations are often accompanied by high-pressure, high-speed fluid impacts on process pipelines and equipment, pipeline vibrations, and displacement of the process ("process" refers to ground equipment and connected pipelines) caused by the swaying of floating platforms. Without pipeline stabilization, the process operations will face significant safety risks from fluid impacts, vibrations, and irregular platform swaying, easily leading to safety accidents such as process leaks and pipeline fatigue ruptures.

[0003] While welding can be used to secure pipelines, offshore oil exploration and development operations are typically temporary, and surface process pipelines laid on the drilling platform deck can only be temporarily welded. Temporary welding would have significant adverse effects on surface equipment and the platform structure, and is generally not recommended by operators.

[0004] Currently, temporary construction equipment and pipelines on offshore platforms are laid directly on the deck, with connected pipelines secured by wire ropes to prevent significant displacement and potential injury to personnel if the pipeline breaks at the joint. However, this method only limits displacement between pipelines to a certain extent and does not secure the pipelines to the platform deck, failing to effectively fix them and restrict process slippage. Existing solutions lack dedicated oil pipeline securing devices, relying primarily on traditional lashing. The contact between the lashing ropes and the pipelines leads to rope wear and, over time, rope breakage, increasing system risk. Utility Model Content

[0035] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0036] like Figure 1-5 As shown, this utility model provides a marine platform oil pipeline fixing device, including: a first fixing mechanism 110, a second fixing mechanism 120, a first pipeline fixing component 130 and a second pipeline fixing component.

[0037] In this embodiment, the first fixing mechanism 110 includes two first fixing arms 111 and a crossbeam 112. The two first fixing arms 111 are arranged in parallel and spaced apart, and the crossbeam 112 connects the two adjacent first fixing arms 111. Correspondingly, the second fixing mechanism 120 includes two second fixing arms 121. The second fixing arms 121 are arranged in a one-to-one correspondence with the first fixing arms 111, and the second fixing arms 121 are detachably connected to the first fixing arms 111. Both the first fixing arms 111 and the second fixing arms 121 have U-shaped structures, and the opening directions of the first fixing arms 111 and the second fixing arms 121 are opposite to each other.

[0038] The first pipeline fixing member 130 is detachably connected to the first fixing mechanism 110. The second pipeline fixing member 140 is detachably connected to the first pipeline fixing member 130 and together with the first pipeline fixing member 130, forms a pipeline clamp structure.

[0039] like Figure 2 As shown, the first fixing mechanism 110 and the second fixing mechanism 120 are arranged opposite each other to form a clamping structure, which can clamp the pipeline fixing device onto the plate-shaped fixing structure 200 of the offshore platform. By installing the pipeline 300 between the first pipeline fixing member 130 and the second pipeline fixing member 140, the pipeline can be fixed on the offshore platform.

[0040] In other embodiments, since the diameter of the pipeline 300 is large, or multiple pipelines 300 need to be fixed at the same time, the number of the first fixing arms 111 in the first fixing mechanism 110 can be increased, and the number of the crossbeams 112 and the second fixing arms 121 can also be increased accordingly.

[0041] As a preferred option, such as Figure 3As shown, the two arms in the U-shaped structure of the first fixed arm 111 have different lengths, and the two arms in the U-shaped structure of the second fixed arm 121 also have different lengths. The long arm 111a of the first fixed arm and the short arm 121a of the second fixed arm are arranged end-to-end opposite each other, as are the short arm 111b of the first fixed arm and the long arm 121b of the second fixed arm. The two ends of the crossbeam 112 are welded to the two long arms 111a of the first fixed arm, and the crossbeam 112 is perpendicular to the long arms 111a of the first fixed arm. The first pipeline fixing member 130 is set on the top of the crossbeam 112; bolt holes 111c are opened on the long arm 111a of the first fixed arm, and the two ends of the first fixing member 130 are respectively connected to the long arm 111a of the first fixed arm by bolts 131; the two ends of the second fixing member 140 are respectively connected to the first fixing member 130 by bolts 141. The axis of the pipeline clamp structure is parallel to the long support arm 111a of the first fixing arm. This arrangement allows the connection position of the crossbeam 121, as well as the connection positions of the first pipeline fixing member 130 and the second pipeline fixing member 140, to be closer to the middle position of the entire pipeline fixing device, thereby ensuring the stability of the pipeline fixing.

[0042] As a further preferred embodiment, the long support arm 111a of the first fixed arm and the short support arm 121a of the corresponding second fixed arm are connected by a connecting screw 101. A bolt hole 121c extends through the short support arm 121a along its length, while a bolt hole 111d is provided at the end of the short support arm of the first fixed arm. The bolt holes 121c and 111d are coaxially arranged. The connecting screw 101 passes through the bolt hole 121c and then connects to the long support arm 111a of the first fixed arm via the bolt hole 111d. By rotating the connecting screw 101, the distance between the first fixed arm 111a and the second fixed arm 121a can be adjusted, allowing the pipeline fixing device to be securely fastened to the plate-shaped fixing structure 200 of the offshore platform. Furthermore, because the distance between the first fixed arm 111a and the second fixed arm 121a can be adjusted using the connecting screw 101, the plate-shaped fixing structure 200 can be adapted to offshore platforms of different sizes (widths).

[0043] As a further preferred embodiment, the short support arm 111b of the first fixed arm and the long support arm 121a of the second fixed arm are of the same length. This makes the short support arm 111b of the first fixed arm and the long support arm 121a of the second fixed arm symmetrical at the bottom of the plate-shaped fixing structure 200 of the offshore platform, which can further ensure the connection stability between the pipeline fixing device and the plate-shaped fixing structure of the offshore platform and prevent lateral deviation.

[0044] A first tightening mechanism 150 is connected to the short support arm 111b of the first fixed arm. The first tightening mechanism includes a support disc 151 and a tightening screw 152. The short support arm 111b of the first fixed arm has a bolt hole 111e. One end of the tightening screw 152 passes through the bolt hole 111e of the short support arm 111b of the first fixed arm and is positioned towards the long support arm 111a of the first fixed arm. The support disc 151 is located between the short support arm 111b and the long support arm 111a of the first fixed arm and is fixedly connected to one end of the tightening screw 152.

[0045] Correspondingly, a second tightening mechanism 160 is connected to the long support arm 121b of the second fixed arm via bolt holes 121d. The structure of the second tightening mechanism 160 is the same as that of the first tightening mechanism 150, and the connection method between the second tightening mechanism 160 and the long support arm 121b of the second fixed arm is the same as the connection method between the first tightening mechanism 150 and the short support arm 111b of the first fixed arm.

[0046] By setting the first clamping mechanism 150 and the second clamping mechanism 160, the pipeline fixing device can clamp the plate-shaped fixing structure 200 of the offshore platform in the thickness direction, thereby further ensuring the fixing effect of the pipeline fixing device.

[0047] The offshore platform oil pipeline fixing device provided by this utility model solves the problems of easy wear and instability of traditional binding methods. The device is compact, easy to disassemble, lightweight, and easy to transport on site. It solves the problem of pipeline slippage caused by the movement of the offshore platform, avoiding the risk of leakage due to pipeline slippage, and has significant economic value.

[0048] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
