Description

Technical Field

[0001] This utility model relates to the field of pipeline fixing technology, and in particular to a pipeline fixing clamp for offshore platforms. Background Technology

[0002] In the operation of offshore platforms, pipeline systems undertake critical tasks such as oil and gas transportation, seawater treatment, and power transmission, and their safe and stable operation is of paramount importance. However, the complexity of the offshore environment presents many severe challenges to pipeline anchoring.

[0003] Offshore platforms are constantly exposed to harsh environments characterized by strong winds, waves, currents, and significant temperature fluctuations. Vibrations caused by strong winds and waves exert continuous dynamic loads on pipelines, leading to constant relative displacement and friction between the pipelines and the fixing clamps. Simultaneously, the high salt spray and high humidity of the marine climate are highly corrosive, gradually eroding the metal components of the pipeline fixing structure and reducing its structural strength and clamping performance. Furthermore, the compact spatial layout of offshore platforms and limited pipeline installation space make precise installation and subsequent maintenance difficult using traditional fixing methods. Moreover, the diverse pipeline specifications on platforms and the poor versatility of traditional fixing clamps make it difficult to meet the fixing requirements of pipelines of different diameters. The combined effect of these factors results in insufficient pipeline fixing stability, making them highly susceptible to loosening, displacement, and even detachment. This seriously threatens the safe operation of offshore platforms, potentially leading to major safety accidents such as leaks and explosions, causing enormous economic losses and environmental damage.

[0004] For example, in patent "201821015075.7, A Lightweight Pipe Clamp for Offshore Oil Platforms," ​​the pipe clamp adopts a clamp-on structure with a semi-circular clamping groove. In practical applications, this structure has a large contact area with the pipe fitting, resulting in poor corrosion resistance in the corrosive marine environment, and the clamping force is easily reduced due to corrosion. Furthermore, the semi-circular clamping groove can only accommodate pipe fittings with specific outer diameters. For pipes of different diameters, different specifications of pipe clamps need to be replaced, lacking flexibility and versatility, and failing to effectively solve the complex problems faced by pipeline fixing on offshore platforms. Therefore, the development of a pipe fixing clamp that can adapt to the complex marine environment, is stable and reliable, and has strong versatility is urgently needed. Utility Model Content

Combined with the height adjustment function of the adjustment unit, this improves the convenience of installation and maintenance, and allows for adaptation to pipes of different specifications, enhancing the clamp's versatility and practicality.

[0020] Please see Figure 1 This utility model provides a pipeline fixing clamp for offshore platforms. The application of clamps in pipeline laying on offshore platforms is extremely necessary due to the stringent requirements for pipeline fixation imposed by the unique marine environment. Offshore platforms are constantly exposed to complex conditions such as wave impact, strong wind vibration, and high salt spray corrosion. Without stable fixation, pipelines are highly susceptible to loosening, displacement, or even detachment under continuous dynamic loads, which can lead not only to production accidents such as oil and gas leaks and power outages, but also to environmental pollution and safety risks. As the connecting hub between the pipeline and the platform structure, the clamp can offset the influence of external loads through stable clamping force, ensuring that the pipeline maintains its predetermined position and attitude under various harsh conditions. It is fundamental to ensuring the safe operation of the pipeline system on offshore platforms.

[0021] From a practical application perspective, the use of clamps in pipeline laying on offshore platforms is an inevitable choice to improve the reliability and economy of the project. Offshore platforms have dense pipeline layouts involving pipes of different specifications and materials. The standardized design of clamps allows for the adaptation and fixing of various types of pipes, reducing the cost of replacing parts due to pipe differences. At the same time, given the limited working space on the platform, the convenient installation and maintenance characteristics of clamps can reduce construction difficulty and subsequent maintenance workload. Furthermore, the corrosion resistance and fatigue resistance of high-quality clamps can extend the service life of the pipeline fixing system, reducing downtime and maintenance losses caused by fixing failures, thus providing assurance for the operation of the offshore platform from a full life-cycle perspective.

[0022] Please see Figure 1 and Figure 2 In this embodiment, the pipe fixing clamp includes a mounting base 100 and a first clamping arm 240 and a second clamping arm 250 symmetrically arranged on both sides of the mounting base 100. The first clamping arm 240 and the second clamping arm 250 are respectively hinged to the mounting base 100 through a first hinge assembly 210 and a second hinge assembly 220 symmetrically arranged. A pipe placement space is provided between the first clamping arm 240 and the second clamping arm 250. Each of the first clamping arm 240 and the second clamping arm 250 has an arc-shaped first clamping surface 261 on its opposite side. The two adjacent ends of the first clamping surface 261 are respectively provided with a second clamping surface 262 and a third clamping surface 263. A protruding tightening contact 264 is provided at the connection between the first clamping surface 261 and the second clamping surface 262. The pipe enters the placement space and contacts the tightening contact 264, causing the placement space to contract and clamping the pipe into the placement space.

[0023] When using this pipe clamp, its operation revolves around the logic of pipe insertion, clamping triggering, and final secure holding. The specific usage is as follows: When it is necessary to fix the pipe, the first clamping arm 240 and the second clamping arm 250 are first pried open to both sides by external force, so that they rotate outward around their respective hinge points (the connection positions of the first hinge assembly 210 and the second hinge assembly 220 with the mounting base 100), or the first clamping arm 240 and the second clamping arm 250 are in their initial (open) state. At this time, the opening of the placement space between the first clamping arm 240 and the second clamping arm 250 is opened to the maximum state, forming a space for the pipe to enter, so as to facilitate the placement of the pipe.

[0024] Subsequently, the pipe to be fixed is aligned with the placement space and inserted. As the pipe gradually enters, its outer surface first contacts the tightening contact 264 at the connection between the first clamping surface 261 and the second clamping surface 262. This protruding structure is key to triggering the clamping action. The pressure of the pipe on the tightening contact 264 generates a reverse force, which is transmitted through the first clamping arm 240 and the second clamping arm 250 to the first hinge assembly 210 and the second hinge assembly 220, forcing the two clamping arms to rotate inward around the hinge point, thereby contracting the originally open placement space.

[0025] Please see Figure 2 and Figure 3 During this process, the arc-shaped first clamping surfaces 261 on opposite sides of the first clamping arm 240 and the second clamping arm 250 gradually conform to the outer surface of the pipe, forming the main circumferential clamping force. Simultaneously, the second clamping surfaces 262 and the third clamping surfaces 263 at both ends of the first clamping surface 261 assist in conforming to the pipe from both sides, further enhancing the contact area and friction. Finally, when the placement space shrinks to match the outer contour of the pipe, the pipe is firmly clamped between the clamping arms, achieving stable fixation.

[0026] The entire process utilizes the action of the pipe itself being inserted to trigger the clamping mechanism, eliminating the need for additional tightening operations. This simplifies the usage process and ensures that the pipe is not easily loosened within the installation space through the cooperation of multiple clamping surfaces.

[0027] For further details, please see Figure 2 and Figure 3 The first clamping arm 240 includes a first clamping plate 241 and a second clamping plate 242 arranged at intervals, and the first clamping plate 241 and the second clamping plate 242 are fixedly connected; the first clamping plate 241 and the second clamping plate 242 are each provided with a first clamping surface 261, a second clamping surface 262 and a third clamping surface 263.

[0028] Furthermore, the second clamping arm 250 includes a third clamping plate 251 and a fourth clamping plate 252 arranged at intervals, the third clamping plate 251 and the fourth clamping plate 252 being fixedly connected; the third clamping plate 251 and the fourth clamping plate 252 are each provided with a first clamping surface 261, a second clamping surface 262 and a third clamping surface 263.

[0029] For further details, please see Figure 3 The second clamping surface 262 and the third clamping surface 263 are both provided as anti-slip surfaces, and the protective surface is provided as a plurality of anti-slip teeth.

[0030] Specifically, the double-layer clamping plate structure of the first clamping arm 240 and the second clamping arm 250 moves synchronously with the pipeline as it enters the installation space during use. The clamping plates, spaced apart, apply clamping force to the pipeline from different radial positions. This design not only distributes the load, preventing localized deformation of the pipeline, but also enhances the rigidity of the clamping arms, making them less prone to bending in the vibration environment of offshore platforms. Furthermore, it adapts to minor unevenness on the pipeline surface, improving overall fit. The first clamping surface 261, the second clamping surface 262, and the third clamping surface 263 on each clamping plate work together, with the arc-shaped main surface providing a circumferential force and the auxiliary surfaces on both sides forming triangular supports to restrict axial sliding of the pipeline, achieving adaptive fixing of pipelines of different diameters.

[0031] The anti-slip teeth on the second clamping surface 262 and the third clamping surface 263 mechanically engage with the pipe surface during clamping. This creates tiny indentations on metal pipes and increases the coefficient of friction on non-metallic pipes. This design effectively prevents the pipe from sliding under dynamic loads such as wave impact and platform sway. Even if the clamps become slightly loose due to long-term use, the anti-slip teeth can still maintain sufficient friction to slow down the loosening process. When the pipe is subjected to external force attempting to detach, the anti-slip teeth also create a self-locking effect, further ensuring clamping stability and meeting the stringent requirements of complex marine environments.

[0032] For further details, please see Figure 1 The mounting base 100 includes a first connecting portion 110 and a second connecting portion 120 disposed on the first connecting portion 110; the second connecting portion 120 includes a first wall edge 141 and a second connecting wall plate 140 disposed at intervals on the first connecting portion 110; the first wall edge 141 includes a first wall edge 141 and a second wall edge 142 and a third wall edge 143 disposed at both ends of the first wall edge 141 in an expanded manner, and the second wall edge 142 and the third wall edge 143 are respectively provided with a fourth wall edge 144 and a fifth wall edge 145 in a converging manner, and the fourth wall edge 144 and the fifth wall edge 145 are connected by a sixth wall edge 146.

[0033] Specifically, in use, the layered structure of the first connecting part 110 and the second connecting part 120 allows the first connecting part 110 to be directly fixed to the ground or other platform components, serving as the basic load-bearing structure of the entire clamp and transferring the weight and force of all components above to the support body. The second connecting part 120, relying on the first connecting part 110, builds a frame for installing the hinge components. The spaced first wall edge 141 and second connecting wall plate 140 form a stable installation space, allowing the first hinge component 210 and the second hinge component 220 to be precisely assembled within it. The purpose of this layered design is to optimize the load transmission path, gradually dispersing the force generated during pipe clamping, preventing damage to local structures due to excessive force, and providing an independent and stable installation reference for the hinge components, ensuring their precise and reliable operation.

[0034] The spacing between the first wall edge 141 and the second connecting wall plate 140 in the second connecting part 120 provides space for the hinge components (such as the first pressure arm 211 and the second pressure arm 221) during use, allowing these components to rotate flexibly between the two wall plates to meet the opening and closing requirements of the clamping arms. Its function is twofold: firstly, the symmetrical structure of the double wall plates provides double-sided support for the hinge components, enhancing the stability of the connection and preventing unilateral tilting of the components under stress; secondly, the spacing facilitates the installation, adjustment, and maintenance of the hinge components, providing sufficient room for operation even in the confined working environment of an offshore platform, thus improving the practicality of the clamp.

[0035] In use, the design of the walls along the first wall edge 141 serves as a reference. The expanding second wall edges 142 and 143 at both ends form large openings, facilitating the smooth external insertion and initial positioning of the hinge assembly. The converging fourth wall edges 144 and 145 on the second and third wall edges 142 and 143 constrain the range of motion of the hinge assembly during operation, preventing structural misalignment due to excessive swaying. Finally, a closed structure is formed by the connection of the sixth wall edge 146, further enhancing overall rigidity. This design ensures convenient installation of the hinge assembly, provides a hinge point for precise control of its movement trajectory, ensures balanced force during pipe clamping, and improves the stability of the clamp under dynamic loads.

[0036] For further details, please see Figure 2 and Figure 3 The first hinge assembly 210 includes a first pressure arm 211, a first connecting arm 212, and a second connecting arm 213. The first pressure arm 211 is disposed between the first wall side 141 and the second connecting wall plate 140, the first clamping plate 241 and the second clamping plate 242, and the first clamping arm 240 and the second connecting part 120 are hingedly connected.

[0037] Furthermore, the second hinge assembly 220 includes a second pressure arm 221, a third connecting arm 222, and a fourth connecting arm 223; the second pressure arm 221 is disposed between the first wall side 141 and the second connecting wall plate 140, the third clamping plate 251 and the fourth clamping plate 252, and the second clamping arm 250 and the second connecting part 120 are hingedly connected.

[0038] Furthermore, both the first pressure arm 211 and the second pressure arm 221 are bent, and the ends of the first pressure arm 211 and the second pressure arm 221 are respectively hinged to a first connecting rod 231 and a second connecting rod 232, and the first connecting rod 231 and the second connecting rod 232 are connected by a third connecting rod 233.

[0039] Furthermore, the first connecting arm 212, the second connecting arm 213, the third connecting arm 222, and the fourth connecting arm 223 are respectively disposed on both sides of the second connecting portion 120.

[0040] The first hinge assembly 210 and the second hinge assembly 220 achieve a flexible connection between the clamping arm and the mounting base 100 through the combination of the pressure arm and the connecting arm. In use, the first pressure arm 211 is positioned between the first wall edge 141, the second connecting wall plate 140, the first clamping plate 241, and the second clamping plate 242, while the second pressure arm 221 is positioned between the corresponding wall plate and the clamping plate. The hinge structure links the clamping arm with the second connecting part 120. The connecting arms are located on both sides of the second connecting part 120, balancing the force and providing space for the pressure arm to rotate, ensuring smooth opening and closing of the clamping arm, allowing for continuous pipe insertion and clamping actions, and enhancing the overall structural stability under dynamic loads.

[0041] Specifically, the bent first pressure arm 211, second pressure arm 221, and connecting rod assembly are key to the synchronicity of clamping. During use, the bent design of the pressure arms amplifies the leverage effect, increasing clamping force at the pipe contact contraction point 264. The first connecting rod 231 and second connecting rod 232 at their ends are connected by a third connecting rod 233, synchronizing the movement of the clamping arms on both sides and preventing unilateral deviation. When operating the third connecting rod 233 or the clamping arm, the connecting rod transmission causes the pressure arms to rotate in a coordinated manner, ensuring uniform contraction or opening of the placement space. Combined with the symmetrical layout of the multiple connecting arms, this further enhances the reliability and accuracy of the clamp for pipe clamping in complex marine environments.

[0042] For further details, please see Figure 1 It also includes an adjustment part 300 for adjusting the installation height of the clamp. The adjustment part 300 includes a top plate 320 and a support leg 310 disposed at the bottom of the top plate 320. The top plate 320 is also provided with a support plate 340 that can be displaced by a screw 330. The mounting base 100 can be detachably disposed on the top of the support plate 340.

[0043] The top plate 320 of the adjustment unit 300 serves as a load-bearing foundation, with its bottom support legs 310 directly contacting the mounting surface to provide stable support for the entire clamp. The height design of the support legs 310 can accommodate minor unevenness of the mounting surface, ensuring that the top plate 320 is level. A support plate 340 on the top plate 320, displaced via a screw 330, can be precisely adjusted in position by rotating the screw 330, thereby driving the mounting base 100 and the entire clamp to move up and down, achieving flexible adjustment of the installation height. This design allows the clamp to quickly adapt to pipeline laying requirements at different heights or in complex installation environments on offshore platforms. When the pipeline's position changes due to thermal expansion and contraction, platform settlement, or other factors, the clamping state remains stable by adjusting the height. Simultaneously, the detachable mounting base 100 facilitates maintenance or replacement of the adjustment unit 300 when needed, improving the clamp's environmental adaptability and service life.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
