Description

Technical Field

[0001] This utility model belongs to the field of offshore wind turbine technology, specifically relating to a jacket positioning device and the jacket. Background Technology

[0002] With the rapid development of the offshore wind power industry, offshore wind turbine jackets, as an important basic structural form, have gradually been widely used. Jacket frames are mainly used to support and fix offshore wind power hydraulic lines, cables, and other pipelines to ensure their safe and reliable operation in the marine environment. As the development of offshore oil and gas resources continues to advance into the deep sea, jacket platforms, as an important offshore oil and gas extraction facility, are increasingly widely used. Jacket platforms are usually composed of jackets and superstructures. The jacket is the basic structure that supports the entire platform. It is buried in the seabed and fixed to the sea surface. Its stability is directly related to the safety and service life of the entire platform.

[0003] Existing jacket positioning devices and jackets are problematic in harsh offshore construction environments. Affected by waves, ocean currents, and other natural factors, jackets are prone to tilting and misalignment during installation, making it difficult to meet high-precision docking requirements. This is especially true in harsh environments such as water depths of hundreds of meters, where significant positioning deviations can prevent precise docking between newly built external platforms and existing platforms, affecting the sliding accuracy of subsequent facilities such as drilling rigs between old and new platforms. Many existing jacket positioning devices are highly specialized, often only suitable for specific pipe diameters. When different pipe diameters are required during construction, positioning frames must be redesigned and manufactured, significantly increasing costs, extending construction time, and reducing operational efficiency. Furthermore, they are clearly inadequate in situations involving water depths of hundreds of meters, harsh offshore construction conditions, the use of pipes of different diameters, and uneven ground environments. Therefore, designing a jacket positioning device and jacket to address these shortcomings is of paramount importance. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a jacket positioning device and the jacket. The device aims to solve the problem that the existing technology is used in harsh marine construction environments. Due to the influence of natural factors such as waves and ocean currents, the jacket is prone to tilting and deviating during installation. Especially in harsh environments such as water depths of hundreds of meters, the positioning deviation is large, which will lead to the inability of newly built external platforms and in-service platforms to dock accurately.

[0007] To solve the above-mentioned technical problems, this utility model provides a guide frame positioning device, which includes a base, a positioning structure at each of the four opposite corners of the upper surface of the base, a fine adjustment structure at the center of the lower surface of the positioning structure, a mounting plate at the center of the lower surface of the fine adjustment structure, and a support structure at the center of the lower surface of the mounting plate.

[0008] The four positioning structures include four positioning frames, which are respectively set at the four opposite corners of the upper end of the base. Each of the four positioning frames has a mounting groove at the center of its upper surface. Each of the four mounting grooves has a first hydraulic telescopic rod at the center of its front inner wall, the center of its rear inner wall, and the center of its two inner side walls.

[0009] When using the device of this technical solution, the positioning frame drives the clamping block through multiple hydraulic telescopic rods to perform horizontal positioning of the guide frame from different directions, improving accuracy. The fine adjustment structure composed of rotating ball and support rod can achieve fine adjustment of the guide frame in the vertical direction of small angles. Furthermore, the height can be independently adjusted according to the flatness of the ground through the second hydraulic telescopic rod. With the help of counterweight, the stability and adaptability of the device are enhanced.

[0010] Preferably, each of the sixteen first hydraulic telescopic rods has a clamping block at its output end, and each of the four positioning frames has a groove at the center of its lower end face near both sides. Each of the four positioning frames has a support column at one of the four opposite corners of its lower end face, and the sixteen support columns are respectively attached to the four opposite corners of the upper end face of the base.

[0011] Furthermore, the support structure includes four second hydraulic telescopic rods, which are respectively set at the four opposite corners of the lower end face of the mounting plate. Counterweights are provided at the center of the lower end face of the mounting plate on both sides, and the output ends of the four second hydraulic telescopic rods are fixedly connected to the base plate.

[0012] Furthermore, the fine-tuning structure includes eight first connecting frames, which are arranged horizontally in groups of four. The two groups of first connecting frames are respectively located at the center of the lower end face of the base and the center of the upper end face of the mounting plate. The four first connecting frames at the top are provided with a first rotating ball at the lower part of their inner center and the four first connecting frames at the bottom are provided with a first supporting rod between the two groups of first connecting frames.

[0013] Furthermore, four second connecting frames are arranged horizontally at the front and rear of the center of the lower end face of the base. Each of the eight second connecting frames has a second rotating ball rotatably connected to its center. Each of the eight second rotating balls has a second support rod at the center of its lower end face. The eight second support rods are respectively set at the front and rear of the center of the upper end face of the mounting plate.

[0014] Furthermore, each of the four positioning frames has a guide frame at its center, and a ladder is located on the front side wall of one of the guide frames.

Detailed Implementation

[0025] This specific embodiment is a catheter stent positioning device and the catheter stent, the structural schematic diagram of which is shown below. Figures 1-6 As shown, the device includes a base 1, with positioning structures 2 at the four opposite corners of the upper surface of the base 1, a fine-tuning structure 4 at the center of the lower surface of the positioning structure 2, a mounting plate 9 at the center of the lower surface of the fine-tuning structure 4, and a support structure 3 at the center of the lower surface of the mounting plate 9.

[0026] First, in this embodiment, the specific structures of the four positioning structures 2 are as follows:

[0027] The four positioning structures 2 include four positioning frames 201, which are respectively set at the four opposite corners of the upper end of the base 1. Each of the four positioning frames 201 has a mounting groove 206 at the center of the upper end face. Each of the four mounting grooves 206 has a first hydraulic telescopic rod 204 at the center of the front inner wall, the center of the rear inner wall, and the center of the two inner side walls.

[0028] Furthermore, each of the sixteen first hydraulic telescopic rods 204 has a clamping block 205 at its output end, and each of the four positioning frames 201 has a groove 203 at the center of its lower end face near both sides. Each of the four positioning frames 201 also has a support column 202 at one of the four opposite corners of its lower end face. The sixteen support columns 202 are respectively attached to the four opposite corners of the upper end face of the base 1. When positioning the guide frame 5 is required, the sixteen first hydraulic telescopic rods 204 will extend or retract synchronously or individually according to the actual situation. This can be achieved by adjusting the extension or retraction length of the first hydraulic telescopic rods 204. The clamping block 205 moves, thus clamping the guide frame 5 placed at the center of the positioning frame 201 from multiple different directions. This allows for precise positioning of the guide frame 5 on the horizontal plane. The groove 203 reduces the weight of the positioning frame 201 without affecting its structural strength, ensuring the functional stability of the positioning frame 201. The support column 202 bears the weight of the positioning frame 201 and smoothly transfers it to the base 1, ensuring the stability and reliability of the positioning frame 201 during positioning, ultimately achieving precise positioning operation.

[0029] Then, the support structure 3 includes four second hydraulic telescopic rods 301, which are respectively set at the four diagonal corners of the lower end face of the mounting plate 9. Counterweights 303 are provided at the center of the lower end face of the mounting plate 9 on both sides. The output ends of the four second hydraulic telescopic rods 301 are fixedly connected to a base plate 302. By controlling the telescopic length of the second hydraulic telescopic rods 301, the overall height of the device can be adjusted, thereby adjusting the overall height and level of the guide frame 5 to adapt to different installation environments and working requirements. When the ground at the installation site is uneven or there are special requirements for the height of the guide frame 5, [the following can be done]. By adjusting the second hydraulic telescopic rod 301, the guide frame 5 can reach the required height and horizontal position. When the second hydraulic telescopic rod 301 extends or retracts, causing the base plate 302 to descend or rise, the base plate 302 can contact the ground or other supporting surfaces, transferring the entire weight of the device to the ground and providing a reliable support point. At the same time, it ensures the overall stability of the device. The counterweight 303 increases the weight at the bottom of the device, lowers the center of gravity of the device, and enhances the overall stability and anti-overturning ability of the device when facing external forces or vibrations generated during equipment operation, preventing the device from shaking or tipping over.

[0030] Furthermore, the fine-tuning structure 4 includes eight first connecting frames 401. The eight first connecting frames 401 are arranged horizontally in groups of four. The two groups of first connecting frames 401 are respectively located at the center of the lower end face of the base 1 and the center of the upper end face of the mounting plate 9. The four first connecting frames 401 at the upper end and the four first connecting frames 401 at the lower end are each provided with a first rotating ball 402. The two groups of first connecting frames 401 are each provided with a first support rod 403.

[0031] The base 1 has four second connecting frames 404 arranged horizontally at the front and rear of its lower end face. Each of the eight second connecting frames 404 has a second rotating ball 405 rotatably connected to its center. Each of the eight second rotating balls 405 has a second support rod 406 at the center of its lower end face. The eight second support rods 406 are respectively located at the front and rear of the center of the upper end face of the mounting plate 9. During the installation of the guide frame 5, due to high installation accuracy requirements or external factors, the guide frame 5 may experience slight positional or angular deviations. At this time, the fine-tuning structure 4 comes into play. Based on the rotatable characteristics of the first rotating ball 402, the two sets of first connecting frames 404... 01 can rotate at a small angle relative to the first rotating ball 402 as the axis, while the first support rod 403 transmits and coordinates the movements of the two sets of first connecting frames 401 in this process, realizing the initial angle fine adjustment of the guide frame 5 in the vertical direction. At the same time, the second connecting frame 404 and the internal second rotating ball 405 and second support rod 406 play an auxiliary fine adjustment role. Through the rotation of the eight second rotating balls 405 and the support and adjustment functions of the second support rod 406, in coordination with the adjustment action of the first connecting frame 401, the position and angle of the guide frame 5 are further precisely adjusted, so that the guide frame 5 reaches a more accurate installation position.

[0032] Finally, each of the four positioning frames 201 has a guide frame 5 at its center. A ladder 6 is located on the front side wall of one of the guide frames 5. Multiple crossbars 7 are arranged vertically and horizontally between the four guide frames 5. A platform 8 is located at the center of the upper surface of the four guide frames 5. The ladder 6 provides a convenient and safe passage for workers. When performing daily inspections, maintenance, or troubleshooting of the guide frames 5, workers can easily go up and down the guide frames 5 using the ladder 6. The multiple crossbars 7 arranged between the guide frames 5 enhance the connection strength and overall stability between the four guide frames 5. This allows the structure of the guide frames 5 to effectively disperse stress when subjected to various external forces and loads, avoiding local stress concentration that could lead to structural damage. The platform 8 provides a usable working surface for the device. Various equipment and tools related to the operation and maintenance of the guide frames 5 can be placed on the platform 8. It also allows workers to perform some operations that need to be performed at height, improving the convenience and efficiency of the work.

[0033] When using the device of this technical solution, by activating the sixteen first hydraulic telescopic rods 204 according to the size of the guide frame 5 and the actual positioning requirements, the clamping blocks 205 are moved by controlling the extension and retraction of the first hydraulic telescopic rods 204, and clamping the guide frame 5 from the front, back and sides simultaneously, quickly fixing the guide frame 5 at the center position of the four positioning frames 201, realizing the initial horizontal positioning of the guide frame 5. Check whether the ground is flat. If the ground is uneven, adjust the length of the four second hydraulic telescopic rods 301 respectively. According to the actual measurement data or observation on site, the second hydraulic telescopic rods 301 at different positions are lengthened or shortened. If the ground in a certain area is low, the second hydraulic telescopic rod 301 at the corresponding position is lengthened so that the base plate 302 lowers to contact the ground. If the ground is high, the second hydraulic telescopic rod 301 at that position is shortened. Finally, all four base plates 302 are tightly attached to the ground, ensuring that the entire device is in a horizontal state, thereby providing a stable support foundation for the guide frame 5.

[0034] During this process, the counterweights 303 on both sides of the lower end face of the mounting plate 9 play a role in ensuring the overall stability of the device by using gravity, preventing the device from shaking or tipping over during the adjustment process. After the initial positioning and support adjustment, it is found that there is a slight angular deviation in the vertical direction of the guide frame 5. At this time, the four first connecting frames 401 of the upper group and the four first connecting frames 401 of the lower group will rotate relative to each other. Relying on the characteristic that the first rotating ball 402 can rotate flexibly, the two groups of first connecting frames 401 can rotate around the first rotating ball 402 at a slight angle. During this process, the first support rod 403 plays the role of connecting and coordinating the actions of the two groups of first connecting frames 401. In this way, the vertical angle of the guide frame 5 can be finely adjusted to achieve a more accurate vertical angle. In addition to the fine adjustment of the vertical angle, the eight second connecting frames 404 and their related components set on the lower end face of the base 1 work together, and the eight second rotating balls 405 can rotate flexibly inside the second connecting frames 404.

[0035] When a slight, barely perceptible positional deviation is found in the horizontal or vertical direction of the jacket frame 5, the rotation of the second rotating ball 405 drives the second support rod 406 to adjust its position and angle. The second support rod 406 transmits the adjustment force to the mounting plate 9 and related structures to further fine-tune the position of the jacket frame 5, ensuring that the jacket frame 5 can be accurately installed at the target position and angle. After the jacket frame 5 is accurately positioned and installed, multiple crossbars 7 are arranged vertically and horizontally between the four jacket frames 5 to play a connecting and reinforcing role, enhancing the stability of the jacket frame 5 as a whole structure, enabling the jacket frame 5 to withstand greater external forces and loads. During daily work, if the staff needs to inspect, maintain, or repair the jacket frame 5, they can safely and conveniently go up and down the jacket frame 5 through the ladder 6 set on the side wall of the jacket frame 5 near the front. The staff can place various tools and equipment on the platform 8 and carry out various operations based on the working surface provided by the platform 8. Moreover, the platform 8 itself remains stable due to the support of the jacket frame 5.

[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
