Abstract
Description
Technical Field
[0001] This utility model belongs to the field of offshore wind power engineering, and in particular relates to a jacket positioning device. Background Technology
[0002] Jacket structures are one of the fundamental components used in offshore wind power facilities. They are fixed to the seabed and provide a stable support structure for the wind turbine.
[0003] During offshore wind power construction, the harsh working environment and short effective working time mean that the jacket structure is typically fixed to the seabed using piles and other structures, which are then secured to the piles. However, due to the influence of seawater waves, the seabed structure is difficult to inspect. If multiple individual piles are driven into the seabed, it takes a long time to confirm their positions. If multiple piles are combined into a single unit before being driven into the seabed, uneven stress distribution can occur, making pile construction more difficult. Utility Model Content
[0004] In view of this, the present invention aims to provide a guide frame positioning device to facilitate the determination of the location of the ground piles and improve construction efficiency.
[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0006] A catheter stent positioning device, comprising
[0007] The positioning frame includes multiple positioning rings and connecting beams, with each end of the connecting beam fixedly connected to a positioning ring.
[0008] Multiple ground piles, each ground pile including an anchoring section and a guide section, the ground pile having a insertion hole along its own axis, the anchoring section being able to be inserted into a positioning ring, and the guide section having a roller on its outer side;
[0009] The bottom of the guide frame extends vertically downward to form a plug-in part corresponding to the ground pile. A hanging ring is provided on the side of the plug-in part, and a gap is left between the hanging ring and the plug-in part. The plug-in part can be inserted into the plug-in hole. The side wall of the guide part can be placed in the gap between the hanging ring and the plug-in part. One end of the rope is fixed to the hanging ring, and the other end can be placed on the side of the guide frame after passing around the roller.
[0010] Furthermore, a space is left between the guide section and the roller for the wire to pass through, and the hanging ring can be placed directly above the space for the wire to pass through.
[0011] Furthermore, the bottom of the jacket and the top of the pile are respectively provided with corresponding flanges, and the jacket and the pile are fixedly connected by the flanges.
[0012] Furthermore, the hanging ring is fixed to the lower surface of the flange at the bottom of the guide frame, and the flange of the ground pile has a groove corresponding to the hanging ring.
[0013] Furthermore, the rope can pass through the slot.
[0014] Furthermore, a limiting edge is provided between the anchoring section and the guide section, and the limiting edge can abut against the upper surface of the positioning ring.
[0015] Furthermore, a positioning spike extends vertically downward from the lower surface of the connecting beam.
[0016] Furthermore, the inner hole of the positioning ring is □-shaped, and the outer circumferential cross-section of the anchoring section is □-shaped.
[0017] Furthermore, the perimeter of the outer cross section of the anchoring section gradually increases from the bottom end to the guide section.
[0018] Compared with the prior art, the catheter stent positioning device of this utility model has the following advantages:
[0019] This utility model uses a positioning frame and ground piles in combination. The positioning frame is first placed on the seabed to determine the position of each ground pile. Then, the ground piles are driven into the seabed through the positioning ring. This allows for quick positioning of the ground piles while avoiding impact on other ground piles during the driving process, thereby improving both project efficiency and project quality.
[0020] By using a positioning spike installed below the connecting beam, the positioning frame can be inserted into the mud and other marine deposits on the seabed to pre-position the positioning frame.
[0021] The cable is positioned using a slot on the flange. While the cable pulls the guide frame down and fixes it, it can also be initially positioned by the cable, making it easier for the insertion part of the guide frame to enter the insertion hole. Attached Figure Description

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0032] The positioning device for the guide frame 3 of this utility model includes a positioning frame 1 that can be fixed relative to seabed mud or other marine deposits. In this embodiment, the positioning frame 1 is square-shaped and includes four positioning rings 11 and four connecting beams 12. The end of each connecting beam 12 is fixedly connected to a positioning ring 11. In other embodiments, in order to maintain the rigidity of the positioning frame 1 or the number of guide frames 3, three or more positioning rings 11 can be provided and connected by connecting beams 12. The connecting beams 12 and the positioning rings 11 can be integrally formed by prefabrication or by welding. Each positioning ring 11 corresponds to a ground pile 2. The ground pile 2 can pass through the positioning ring 11 and be driven into the seabed to complete the fixation. Those skilled in the art should know how to drive the ground pile 2 into the seabed, which will not be described in detail here. The lower surface of the connecting beam 12 also extends downwards to form a positioning spike 13. During construction, the positioning frame 1 can penetrate the mud and marine deposits on the seabed or get stuck in the rock crevices by its own weight and the positioning spike 13, thus completing the initial fixation of the positioning frame 1 and avoiding the impact of underwater currents and other factors that could cause the positioning frame 1 to deviate from its predetermined position.
[0033] Each pile 2 includes an anchoring section 21 and a guide section 22, and a limiting edge 29 is provided between the anchoring section 21 and the guide section 22. When the pile 2 passes through the positioning ring 11, the limiting edge 29 can abut against the upper surface of the positioning ring 11. The pile 2 has an insertion hole 23 along its own axial direction, and the anchoring section 21 can be inserted into the positioning ring 11. At the same time, in order to facilitate the insertion of the anchoring section 21 into the positioning ring 11, the perimeter of the outer cross section of the anchoring section 21 gradually increases from the bottom end to the guide section 22, so that the anchoring section 21 has a structure that is thinner at the bottom and thicker at the top, and the cross section at the bottom end of the anchoring section 21 is smaller than the cross section of the inner hole of the positioning ring 11. The guide section 22 has rollers 25 on the outer side of the frame surrounding the positioning frame 1. Through the cooperation of the positioning ring 11 and the limiting edge 29, the rollers 25 are prevented from contacting the seabed soil, thus avoiding any impact on their rotation. This also facilitates later control of the guide frame 3's ropes passing through the rollers 25. To ensure that the rollers 25 are positioned outside the positioning frame 1 during installation, the inner hole of the positioning ring 11 has a □-shaped cross-section, and the outer wall of the anchoring section 21 also has a □-shaped cross-section, preventing the ground piles 2 from rotating during driving into the seabed. The outer wall of the guide section 22 has connecting lugs 24, and the rollers 25 are rotatably connected to the connecting lugs 24. A cable passage space 26 is left between the rollers 25 and the side wall of the guide section 22.
[0034] The bottom of the guide frame 3 extends vertically downward to form a connector 31 corresponding to the ground pile 2. A hanging ring 33 is provided on the side of the connector 31, with a gap between the hanging ring 33 and the connector 31. The connector 31 can be inserted into the connector hole 23. The side wall of the guide portion can be placed within the gap between the hanging ring 33 and the connector 31. One end of the rope is fixed to the hanging ring 33, and the other end can pass around the roller 25 and be placed on the side of the guide frame 3, extending upwards to facilitate the movement of the rope by construction personnel and machinery, allowing the guide frame 3 to fall to the predetermined position. Specifically, the top of the connector 31 is provided with a first flange 32, and the hanging ring 33 is fixed to the lower surface of the first flange 32 by welding or other means. The top of the ground pile 2 is provided with a second flange 27, and a slot 28 is opened on the second flange 27, with the slot 28 positioned directly above the roller 25, allowing the rope to pass vertically through the second flange 27, then through the cable passage space 26, and around the roller 25. Meanwhile, as the guide frame 3 gradually descends, the hanging ring 33 can pass through the slot 28 and be positioned directly above the cable passage space 26. At this time, the first flange 32 and the second flange 27 are connected to each other and can be connected by bolts, etc.
[0035] In the construction process of the positioning device for the guide frame 3 described in this utility model, the positioning frame 1 is first hoisted and lowered into the sea, and the positioning frame 1 is fixed in the predetermined position by the positioning spike 13. Then, multiple ground piles 2 are driven into the seabed through the positioning ring 11 to complete the fixing of the ground piles 2. After that, the guide frame 3 is installed horizontally or vertically, and the insertion part 31 of the guide frame 3 is inserted into the insertion hole 23 of the ground pile 2. Mud can then be poured in to complete the fixing of the guide frame 3. In this embodiment, optionally, a rope is threaded through the roller 25 of the ground pile 2, and one end of the rope is then fixed to the hanging ring 33 of the guide frame 3 by binding or other means. The other end is connected to the engineering machinery (such as a tugboat) so that the engineering machinery applies tension to the guide frame 3 through the rope. Then, the guide frame 3 is lifted by a crane and moved to a predetermined position so that the rope between the guide frame 3 and the ground pile 2 remains vertical. By pulling the rope and controlling the crane, the guide frame 3 is lowered until the insertion part 31 is inserted into the guide section 22. The guide frame 3 continues to fall to complete the positioning of the guide frame 3, and then the guide frame 3 is fixed by grouting or other means. Those skilled in the art should know how the guide frame 3 is fixed, and it will not be described in detail here. After installation, the rope can be cut at a preset position or the rope can be separated from the ring.
[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
