Description

Technical Field

[0001] This utility model relates to the field of marine engineering technology, and in particular to a flipping device for a flexible hose protective cover made of fiberglass. Background Technology

[0002] Steel grating covers are currently widely used for the structural protection of underwater oil and gas facilities. However, these covers have two major problems: first, they are heavy and require the addition of anode blocks for corrosion protection, resulting in high installation and maintenance costs; second, the metal material is prone to corrosion, leading to unstable performance over long-term use and requiring regular replacement.

[0003] Fiberglass reinforced materials are lightweight, high-strength, and extremely resistant to marine corrosion. Fiberglass hose protective covers, derived from this material, are gradually replacing steel grating covers for protecting underwater oil and gas facilities. However, this structure also has some drawbacks: firstly, its light weight makes it susceptible to hydrodynamic effects when passing through splash zones; secondly, the material is relatively brittle, making its edges prone to stress concentration damage during transport before entering the water.

Therefore, features defined with "first," "second," "third," etc., may explicitly or implicitly include one or more of that feature. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0020] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0021] Please refer to Figure 1 This application constructs a flipping device 100 for a fiberglass hose protective cover 200. The fiberglass hose protective cover 200 can be fixedly installed in the flipping device 100. Then, using a crane or other working equipment, one side of the flipping device 100 with the fiberglass hose protective cover 200 installed is lifted, causing the flipping device 100 to flip until the side of the flipping device 100 that is perpendicular to the ground (which can be understood as a deck) is flipped 90° (see reference). Figure 2 Then, continue to lift the device 100 off the ground, and move it above the sea surface for a quick vertical entry into the water, thereby effectively suppressing the impact of waves on the fiberglass hose protective cover 200 during entry into the water.

[0022] Understandably, this tilting device 100 can avoid the influence of weather windows, smoothly pass through the splash zone, thereby obtaining a wider installation window and improving the efficiency of offshore construction. Specifically, when there are no good weather windows, when the wave height is greater than 0.5m, the impact and undulation of the waves will reduce the projected area of ​​the structure on the water surface, causing severe overload of the crane hook. The splash zone refers to the outer surface of a structure or pipe that is periodically surrounded by water or outside the water due to the action of waves and tides; it can also be understood as the boundary between seawater and air. This tilting device 100 is designed to allow the fiberglass hose protective cover 200 to be vertically inserted into the water under conditions where there are no good weather windows, reducing the projected area of ​​the hose and thus smoothly passing through the splash zone. Of course, when there are good weather windows, this tilting device 100 can be used as a counterweight frame for the horizontal installation of the fiberglass hose protective cover 200, thereby achieving rapid water entry.

[0023] Please see Figure 1 The flipping device 100 of the fiberglass hose protective cover 200 mainly includes a main frame 1 and straps 2 for fixing the fiberglass hose protective cover 200 to the main frame 1. Flipping lifting points 3 and arc-shaped components 4 are respectively provided on opposite sides of the main frame 1. The flipping lifting points 3 are fixedly connected to one side of the main frame 1 to provide a foundation for the flipping operation of the flipping device 100. The arc-shaped components 4 are fixedly connected to the other side of the main frame 1 to act as a support point against the ground when the flipping device 100 is performing the flipping operation, and the arc-shaped structure assists in completing the flipping operation.

[0024] Understandably, see also Figure 2 The crane can connect to the flipping lifting point 3 through its rigging to lift one side of the flipping device 100 upward. At this time, the entire flipping device 100 will rotate from 0° to 90° along the outer arc side of the arc part 4 with the arc part 4 as the rotation base point until it is perpendicular to the ground. Then it will continue to be lifted to leave the ground and complete the flipping operation.

[0025] The following example illustrates the specific structure of the flipping device 100 of the fiberglass hose protective cover 200.

[0026] For reference Figure 3The main frame 1 may include a support base 11 and lateral railings 12 surrounding the perimeter of the support base 11. The support base 11 can support the weight of the fiberglass hose protective cover 200 before the overturning operation and provide the necessary rigidity during the overturning operation. The lateral railings 12 on each side can prevent the fiberglass hose protective cover 200 from detaching from the main frame 1, and at least one lateral railing 12 can support the weight of the fiberglass hose protective cover 200 during the overturning operation. Straps 2 can be attached to and locked to the lateral railings 12 to secure the fiberglass hose protective cover 200 to the support base 11.

[0027] The main frame 1 can be constructed from cylinders and flat steel. The cylinders form the main structure of the overall frame (for example, the outer frame of the support base 11 and the side railings 12 are constructed from cylinders), while the flat steel forms the inner circumferential structure of the support base 11. The horizontal spacing between the flat steel sections can be no more than 1 meter. The size of the main frame 1 can be adapted to the size of the fiberglass flexible hose protective cover 200 that needs protection. It should be further noted that using flat steel sections in the main frame 1 reduces the spacing within the frame, thus allowing for the adaptation of fiberglass flexible hose protective covers 200 of various sizes.

[0028] See also Figure 3 Several stop frames 5 can be installed on the side railing 12, and the straps 2 can be threaded through the lug holes of the fiberglass flexible hose protective cover 200 (see reference). Figure 1 Furthermore, the two ends of the strap 2 are respectively wrapped around two different stop frames 5 and connected and secured. The stop frames 5 can prevent the strap 2 from slipping and loosening during the flipping operation, and can support the strap 2 to provide sufficient tension so that the fiberglass hose protective cover 200 is bound to the main frame 1, ensuring the safety of construction.

[0029] Several horizontal lifting points 6 can also be installed on the side railing 12 for the routine transport of the fiberglass hose protective cover 200. The crane can connect its rigging to the horizontal lifting points 6 to horizontally lift the tilting device 100.

[0030] In this embodiment, as Figure 3As shown, the flipping lifting point 3 and the arc-shaped component 4 are respectively arranged on both sides of the main frame 1 along its length. Several stop frames 5 are symmetrically arranged on both sides of the main frame 1 along its width, and several stop frames 5 are also arranged on the side of the main frame 1 facing the same direction as the flipping lifting point 3. This flipping device 100 is equipped with multiple straps 2, one portion of which passes through the lifting lug holes of the fiberglass flexible hose protective cover 200, and its two ends are respectively tied to two side rails 12 in the width direction of the main frame 1; another portion of the straps 2 passes through the lifting lug holes of the fiberglass flexible hose protective cover 200, and its two ends are tied to the side rails 12 on the same side as the flipping lifting point 3. Furthermore, several horizontal lifting points 6 are symmetrically arranged on both sides of the main frame 1 along its width.

[0031] For ease of explanation, the two sides along the length of the main frame 1 are referred to as the first side and the second side, respectively. The side with the flipping lifting point 3 is defined as the first side, and the side with the arc-shaped component 4 is defined as the second side.

[0032] The flip-up lifting point 3 is fixedly connected to the side railing 12 on the first side and is located on the side of the side railing 12 facing away from the second side. In this embodiment, there are two flip-up lifting points 3.

[0033] In addition, such as Figure 3 As shown, a triangular structure is also formed on the first side of the main frame 1 to strengthen the structural strength at the first side position. In this embodiment, triangular structures are formed at the top of the side railing 12 on the first side and between the side railing 12 on the first side and the supporting base 11.

[0034] See also Figure 3 The arc-shaped component 4 protrudes from the main frame 1. Meanwhile, the side railing 12 on the second side is also provided with an extension column 13 extending in a direction away from the first side. One end of the arc-shaped component 4 is connected to the support base 11 on the structure on the second side, preferably vertically connected to the side of the structure away from the first side, and the other end of the arc-shaped component 4 is connected to the extension column 13, forming a fan-shaped structure together.

[0035] The arc-shaped component 4 is designed as a quarter-circular arc to reduce resistance during the flipping operation, making it easier for the flipping device 100, which is equipped with a fiberglass hose protective cover 200, to flip. During the flipping operation, the arc-shaped component 4 is in contact with the ground, bears the entire weight of the operation, and assists the flipping device 100 in completing the transition from 0° to 90°.

[0036] In this embodiment, there are two arc-shaped components 4, which respectively form two fan-shaped structures.

[0037] See also Figure 3On the second side of the main frame 1, a load-bearing side plate 14 is also provided for supporting the fiberglass hose protective cover 200 during the overturning operation. A rubber component (not shown) is provided on the same side as the first side of the load-bearing side plate 14. During the overturning process, the weight of the fiberglass hose protective cover 200 will gradually increase on the load-bearing side plate 14. The rubber component can provide cushioning to prevent the fiberglass hose protective cover 200 from being damaged by concentrated stress and thus from brittle damage.

[0038] A reinforcing rib 15 is also provided between the load-bearing side plate 14 and the lateral railing 12 on the second side. The reinforcing rib 15 serves as a structural strength enhancement component between the load-bearing side plate 14 and the lateral railing 12 on the second side, which can improve the stability and safety of the tilting device 100 during the tilting process.

[0039] In summary, this application provides a quick-access water-immersion flipping device 100 for a fiberglass hose protective cover 200, which can also be used as an overlapping flipping device 100 for other fiberglass protective covers. This flipping device 100 offers multiple advantages: it not only prevents the fiberglass hose protective cover 200 from making hard contact with the ground, but also improves construction efficiency and effectively suppresses the impact of hydrodynamic impact in the splash zone; the water-immersion installation method of the protective cover can be flexibly selected according to actual construction needs (such as weather conditions). The design of the arc-shaped component 4 not only improves flipping efficiency but also avoids stress concentration between the fiberglass hose protective cover 200 and the ground, significantly reducing the risk of edge damage. Therefore, this flipping device 100 enables rapid operation during the offshore installation phase, playing a positive role in improving installation efficiency and reducing costs.

[0040] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
