Description

Technical Field

[0001] This invention relates to the field of offshore wind power equipment installation technology, specifically to a method and device for installing and positioning a support plate for an offshore wind power ATP (Airtight Platform). Background Technology

[0002] The horizontal installation quality of the offshore wind power ATP airtight platform directly affects the safety performance and functionality of the overall structure. The platform support plate welded to the column is the core support component to ensure the platform's levelness, and its installation and positioning must meet the high-precision tolerance requirement of ±2mm in both the horizontal and vertical directions.

[0003] Reference Figure 4 The diagram shows a traditional installation scenario for the support plates of an offshore wind power ATP (Automatic Train Protection) airtight platform, involving manual marking and total station positioning. Currently, the traditional installation method for support plates mainly relies on total station positioning, manual marking, and spot welding. In practice, construction workers first determine the approximate position of the support plates by marking lines, and then perform preliminary spot welding. If subsequent measurements reveal positional deviations, adjustments can only be made by repeatedly disassembling, reassembling, and re-spotting. This method has significant drawbacks: First, manual marking inevitably introduces visual errors, and even with the aid of auxiliary equipment such as levels, it is difficult to accurately control the spatial position of the support plates. Second, there is a lack of targeted and precise adjustment methods, making it impossible to efficiently correct deviations once they occur. Third, the construction quality depends on the skill level of the personnel; differences in error caused by different operators further exacerbate the cumulative error of multiple support plates, making it difficult to maintain the same horizontal line at each support point.

[0004] The aforementioned problems directly lead to the inefficiency and high rework rate of traditional installation methods, which not only increases construction time and costs but also wastes materials. Furthermore, insufficient installation accuracy may affect subsequent platform assembly and even create structural safety hazards. Summary of the Invention

[0005] This invention aims to solve the problems of insufficient accuracy, cumbersome operation, and low efficiency in the installation and positioning of support plates for traditional offshore wind power ATP airtight platforms, and provides an installation and positioning method and device that is accurate in positioning, convenient in operation, and cost-controllable.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0007] The first aspect of the present invention provides an installation and positioning device for a support plate of an offshore wind power ATP (Automatic Guided Platform) airtight platform, comprising:

[0008] A connecting base is used for detachable connection with the column of the offshore wind power ATP airtight platform.

[0009] An adjustment assembly includes multiple adjustment components, each of which is mounted on the connecting base and has one end that can abut against a support plate. By rotating the adjustment components, the support plate can be driven to move slightly in the horizontal and / or vertical directions, thereby achieving fine-tuning of the position of the support plate.

[0010] As a further improvement to the technical solution of the present invention, the connecting base includes a panel, a base plate, and an ear plate. The panel is used for spot welding and fixing to the column. The base plate is fixed to the outside of the panel. The ear plate is fixed to the base plate. The adjusting member is installed on the base plate and / or the ear plate.

[0011] As a further improvement to the technical solution of the present invention, the adjusting component is a screw and nut mating structure, the seat plate and the ear plate are provided with through holes, the nut is welded to one side of the through hole, the screw is threadedly connected to the nut, and one end of the screw extends out of the through hole to abut against the support plate.

[0012] As a further improvement to the technical solution of the present invention, the adjustment component includes a horizontal adjustment component and a vertical adjustment component. The horizontal adjustment component is provided in four sets and is symmetrically installed on the ear plates on the left and right sides of the support plate. The vertical adjustment component is provided in four sets and is installed on the base plates at the four corners of the bottom of the support plate.

[0013] As a further improvement to the technical solution of the present invention, the materials of the panel, the seat plate and the ear plate are Q235 steel, the thickness of the panel is 15mm, and the thickness of the seat plate and the ear plate is 10mm.

[0014] The second aspect of this invention provides a method for installing and positioning a support plate for an offshore wind power ATP (Automatic Tolerancing Platform), comprising the following steps:

[0015] Step S1: Fix the connecting base to the preset position of the column of the offshore wind power ATP airtight platform;

[0016] Step S2: Place the support plate on the adjusting member of the adjusting assembly, so that the adjusting member abuts against the support plate;

[0017] Step S3: Measure the actual installation coordinates of the support plate using a total station;

[0018] Step S4: Based on the measurement results, rotate the corresponding adjusting component to drive the support plate to make minor adjustments in the horizontal and / or vertical directions until the coordinates of the support plate meet the design requirements;

[0019] Step S5: Spot weld the finely adjusted support plate to the column to fix it, and complete the installation and positioning.

[0020] As a further improvement to the technical solution of the present invention, in step S1, the connecting base is fixed to the column of the offshore wind power ATP airtight platform by spot welding through the panel, and the panel is symmetrically arranged on both sides of the column of the offshore wind power ATP airtight platform.

[0021] As a further improvement to the technical solution of the present invention, in step S4, the horizontal fine adjustment is achieved by rotating the horizontal adjustment pieces on the left and right sides, and the vertical fine adjustment is achieved by rotating the vertical adjustment pieces at the four corners of the bottom.

[0022] As a further improvement to the technical solution of the present invention, in step S4, the measurement and fine-tuning steps are repeated multiple times until the horizontal and vertical tolerances of the support plate do not exceed ±2mm.

[0023] As a further improvement to the technical solution of the present invention, after step S5 is completed, the installation positioning device is removed and can be reused.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] This invention provides a stable installation foundation for the adjustment components through a detachable connecting base, avoiding the problem of difficulty in retrieving the base after it is fixed to the column. At the same time, multiple sets of rotatable adjustment parts directly abut against the support plate, realizing small-amplitude and / or vertical precise driving of the support plate. This effectively solves the defects of traditional manual marking positioning with large errors and lack of precise adjustment methods. It can stably control the installation tolerance of the support plate within ±2mm. Moreover, the overall structure of the device is simple, and most of the components are standard or easy-to-process parts, resulting in low manufacturing cost. It is adaptable to the installation requirements of support plates of different specifications, laying the foundation for subsequent efficient positioning. By adopting the installation and positioning device for the support plate of the offshore wind power ATP airtight platform, the base is first fixed to ensure the stability of the installation benchmark. Then, combined with the precise measurement of the total station and the targeted fine-tuning of the adjustment components, the deviation can be corrected through multiple measurement-fine-tuning cycles. This avoids the tedious operation of repeated disassembly and assembly in traditional methods, greatly shortening the installation time. At the same time, it can strictly ensure that the horizontal and vertical tolerances of the support plate do not exceed ±2mm, effectively avoiding the cumulative error of multiple support plates. After installation, the device can be disassembled and reused, reducing material waste and rework costs, and ultimately improving the overall installation quality and construction efficiency of the offshore wind power ATP airtight platform.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Reference Figures 1 to 3 In a first aspect, the present invention provides an installation and positioning device for a support plate of an offshore wind power ATP (Automatic Guided Platform) airtight platform, comprising:

[0035] Connecting base 3, which is used for detachable connection with the column 1 of the offshore wind power ATP airtight platform;

[0036] The adjustment assembly includes multiple adjustment components 4, which are installed on the connecting base 3. One end of each adjustment component 4 can abut against the support plate 2. By rotating the adjustment component 4, the support plate 2 can be driven to move slightly in the horizontal and / or vertical directions, thereby achieving fine-tuning of the position of the support plate 2.

[0037] The installation and positioning device for the support plate of the offshore wind power ATP airtight platform of the present invention achieves precise positioning of the support plate 2 through the cooperation of the connecting base 3 and the adjustment component. The connecting base 3 is used to establish a detachable connection with the column 1 of the offshore wind power ATP airtight platform. It can be fixed to a preset position on the column by conventional detachable fixing methods such as spot welding and snap-fitting, providing a stable installation benchmark for the adjustment component. The adjustment component includes multiple adjusting parts 4 mounted on the connecting base 3. One end of the adjusting part 4 can form an abutment fit with the support plate 2 to be installed. When the position of the support plate 2 needs to be adjusted, by rotating the adjusting part 4, the relative movement between the adjusting part 4 and the connecting base 3 (such as threaded transmission, linear sliding, etc.) drives the support plate 2 to move slightly in any one or both directions simultaneously in the horizontal and vertical directions, thereby achieving fine-tuning of the position of the support plate 2 during the installation and positioning process, ensuring that it meets the design coordinate requirements. The device, with its detachable base 3, ensures benchmark stability during installation and avoids the problem of material waste caused by the inability to recycle traditional fixed bases. Simultaneously, the design of directly driving the support plate 2 using the adjusting component 4 effectively solves the shortcomings of traditional manual marking and positioning, which suffers from low accuracy and lack of precise adjustment methods. This enables precise, small-amplitude adjustments of the support plate 2 in multiple directions, laying the foundation for controlling the installation tolerances of the support plate 2 within the design requirements. Furthermore, the device has a simple overall structure, few components, and a flexible layout, making it adaptable to the installation needs of support plates for offshore wind power ATP airtight platforms of different specifications. It has a wide range of applications and low manufacturing and maintenance costs.

[0038] In some embodiments, the connecting base 3 includes a panel 31, a base plate 32, and an ear plate 33. The panel 31 is used for spot welding to the column. The base plate 32 is fixed to the outside of the panel 31. The ear plate 33 is fixed to the base plate 32. The adjusting member 4 is installed on the base plate 32 and / or the ear plate 33.

[0039] It should be noted that the specific structure of the connecting base 3 consists of a panel 31, a base plate 32, and an ear plate 33. The panel 31 serves as the connecting carrier between the connecting base 3 and the column, and is fixed to the column by spot welding. The spot welding strength is sufficient to ensure that the base does not shift during adjustment, while also facilitating removal after subsequent installation. The base plate 32 is fixed to the outside of the panel 31, and its fixing method can be welding. The position of the pre-set opening on the base plate 32 is based on the size of the support plate 2 to be installed. The size of the opening is sufficient to allow the adjusting component 4 to move normally without creating excessive gaps. The ear plate 33 is fixed to the base plate 32, and can also be fixed by welding. The adjusting component 4 is selectively installed on the base plate 32 or the ear plate 33 according to the adjustment requirements, forming adjustment support for the support plate 2 in different directions.

[0040] This invention, by dividing the connecting base 3 into a combined structure of panel 31, seat plate 32, and ear plate 33, allows for the design of the structure and dimensions of each component to meet different functional requirements, such as connection with the column, installation of the adjusting component 4, and support of the support plate 2, making the overall structure of the base more reasonable. The panel 31, fixed by spot welding, balances connection stability and detachability, avoiding permanent damage to the column and facilitating subsequent device recovery. The seat plate 32 has pre-drilled holes according to the dimensions of the support plate 2, ensuring precise installation of the adjusting component 4 and guaranteeing its stable operation. The ear plate 33, in conjunction with the seat plate 32, further expands the installation position of the adjusting component 4, better adapting to the adjustment needs of the support plate 2 in different directions and improving the overall adjustment reliability of the device.

[0041] In some embodiments, the adjusting member 4 is a mating structure of screw 41 and nut 42. The seat plate 32 and ear plate 33 are provided with through holes. The nut 42 is welded to one side of the through hole. The screw 41 is threadedly connected to the nut 42, and one end of the screw 41 extends out of the through hole to abut against the support plate 2.

[0042] Adjusting component 4 is a mating structure of screw 41 and nut 42, specifically implemented as follows: Through holes are made in the base plate 32 and ear plate 33, the inner diameter of the through holes is adapted to the outer diameter of screw 41, ensuring that screw 41 can pass smoothly through the through holes; nut 42 is welded to one side of the through hole, the welding position must ensure that the internal thread of nut 42 is coaxial with the through hole, so that screw 41 can form a stable threaded connection with nut 42; during assembly, screw 41 passes through the through hole and engages with nut 42 threadedly, and one end of screw 41 protrudes from the through hole. When support plate 2 is placed on the device, this protruding end abuts against the surface of support plate 2; when the position of support plate 2 needs to be adjusted, screw 41 is rotated, and the threaded transmission between screw 41 and nut 42 causes screw 41 to move axially, thereby pushing or pulling support plate 2 to move slightly in the corresponding direction, realizing fine-tuning of position.

[0043] The screw 41 and nut 42 are used as the adjusting component 4. By utilizing the high precision characteristics of the threaded transmission, the support plate 2 can be precisely adjusted in small ranges, effectively solving the problem of insufficient precision in traditional adjustment methods and ensuring that the installation tolerance of the support plate 2 meets the design requirements. The nut 42 is welded to one side of the through hole, which can prevent the nut 42 from loosening or shifting during the adjustment process, ensuring the stability of the adjusting component 4 and thus improving the reliability of fine adjustment. At the same time, the screw 41 and nut 42 are conventional standard parts, which are easy to obtain and have low cost, which can reduce the overall manufacturing cost of the device. Moreover, the threaded structure is not easily damaged, which is convenient for long-term repeated use and extends the service life of the device.

[0044] In some embodiments, the adjustment assembly includes a horizontal adjustment member and a vertical adjustment member. The horizontal adjustment member is provided in four sets and is symmetrically installed on the ear plates 33 on the left and right sides of the support plate 2. The vertical adjustment member is provided in four sets and is installed on the seat plates 32 at the four bottom corners of the support plate 2.

[0045] It should be noted that four sets of horizontal adjustment components are symmetrically installed on the ear plates 33 on the left and right sides of the support plate 2. The end of the screw 41 of each set of horizontal adjustment components abuts against the side surface of the support plate 2. When the screw 41 of the left horizontal adjustment component is turned, the support plate 2 can be pushed to the right. When the screw 41 of the right horizontal adjustment component is turned, the support plate 2 can be pushed to the left. The horizontal position of the support plate 2 can be finely adjusted by the cooperation of the adjustment components on the left and right sides. Four sets of vertical adjustment components are installed on the base plates 32 at the four corners of the bottom of the support plate 2. The end of the screw 41 of each set of vertical adjustment components abuts against the lower surface of the support plate 2. When the screw 41 of the vertical adjustment component in a certain corner is turned, the support plate 2 in that corner can be pushed upward. When the screw 41 of the opposite corner is turned, the levelness of the support plate 2 can be adjusted. The vertical height adjustment and levelness calibration of the support plate 2 can be achieved by the cooperation of the four sets of vertical adjustment components.

[0046] Four sets of horizontal adjustment components are symmetrically installed on both sides of the support plate 2, providing adjustment force from two dimensions in the horizontal direction of the support plate 2. This avoids tilting of the support plate 2 caused by unilateral adjustment and ensures the stability and accuracy of horizontal adjustment. Four sets of vertical adjustment components are installed at the four corners of the bottom of the support plate 2, allowing for individual height adjustment of the four support points of the support plate 2. This not only enables adjustment of the overall vertical height but also allows for targeted calibration of the levelness of the support plate 2, effectively solving the problem of maintaining the same horizontal line among multiple support points in traditional installation methods and avoiding the generation of cumulative errors. The clear division of labor and close cooperation between the horizontal and vertical adjustment components enable comprehensive adjustment of the support plate 2 in multiple dimensions, further improving the installation positioning accuracy.

[0047] In some embodiments, the panel 31, the base plate 32, and the ear plate 33 are made of Q235 steel, the panel 31 has a thickness of 15mm, and the base plate 32 and the ear plate 33 have a thickness of 10mm.

[0048] It should be noted that the panel 31, the base plate 32, and the ear plate 33 are all made of Q235 steel. This material has good strength and toughness, and can withstand the weight of the support plate 2 and the force during the adjustment process, meeting the stress requirements of offshore wind power on-site construction. Among them, the thickness of the panel 31 is set to 15mm. The thicker thickness can enhance the connection stability between the panel 31 and the column and avoid deformation of the panel 31 due to excessive force after spot welding. The thickness of the base plate 32 and the ear plate 33 is set to 10mm. While ensuring sufficient strength to support the adjustment component 4 and the support plate 2, it avoids excessive thickness of the components, which would increase the overall weight of the device and facilitate on-site transportation and installation.

[0049] Q235 steel is a commonly used steel in the industrial field. It is readily available and inexpensive, which can reduce the material cost of the equipment. At the same time, its good weldability facilitates the fixed connection between the panel 31, the base plate 32, and the ear plate 33, ensuring that the connection of each component is firm. The panel 31 adopts a 15mm thickness design, which effectively improves the load-bearing capacity of the connection between the base and the column, avoids the deformation of the base during installation and adjustment, and ensures the stability of the installation benchmark. The base plate 32 and the ear plate 33 adopt a 10mm thickness design, which achieves lightweighting while meeting the strength requirements, reduces the labor intensity of equipment handling and installation, and improves construction convenience. In addition, Q235 steel has a certain degree of corrosion resistance, which can adapt to the humid and salt spray environment of offshore wind power sites, extending the service life of the equipment.

[0050] The second aspect of this invention provides a method for installing and positioning a support plate for an offshore wind power ATP (Automatic Tolerancing Platform), comprising the following steps:

[0051] Step S1: Fix the connecting base 3 to the preset position of the column 1 of the offshore wind power ATP airtight platform;

[0052] Step S2: Place the support plate 2 on the adjusting member 4 of the adjusting assembly, so that the adjusting member 4 abuts against the support plate 2;

[0053] Step S3: Measure the actual installation coordinates of the support plate 2 using a total station;

[0054] Step S4: Based on the measurement results, rotate the corresponding adjusting component 4 to drive the support plate 2 to make minor adjustments in the horizontal and / or vertical directions until the coordinates of the support plate 2 meet the design requirements;

[0055] Step S5: Spot weld the finely adjusted support plate 2 to the column to complete the installation and positioning.

[0056] The specific implementation steps are as follows: First, fix the connecting base 3 to the preset position of the column 1 of the offshore wind power ATP airtight platform, and establish a stable installation benchmark through the detachable connection (such as spot welding) between the panel 31 and the column; Second, place the support plate 2 to be installed on the adjusting component 4 of the adjusting assembly, so that the end of the adjusting component 4 fully abuts against the surface of the support plate 2, ensuring that the adjusting component 4 can effectively drive the support plate 2 to move; Third, use a total station to measure the actual installation coordinates of the support plate 2 and obtain the deviation data between it and the design coordinates in the horizontal and vertical directions; Fourth, according to the measured deviation data, rotate the corresponding adjusting component 4 in a targeted manner, and drive the support plate 2 to make fine adjustments in the horizontal or vertical direction through the movement of the adjusting component 4. If the requirements are not met in one fine adjustment, the measurement and fine adjustment steps can be repeated until the coordinates of the support plate 2 meet the design requirements; Fifth, fix the support plate 2, which has been adjusted to the position, to the column by spot welding to complete the installation and positioning of the support plate 2.

[0057] This invention establishes a stable benchmark by first fixing the base 3, avoiding the problem of benchmark deviation in traditional installations. Combined with the precise measurement of a total station and the targeted fine-tuning of the adjustment components, it can acquire and quickly correct the positional deviation of the support plate 2 in real time, effectively replacing the tedious operations of repeated disassembly, re-welding, and re-installation in traditional methods, significantly shortening installation time. Through multiple cycles of measurement and fine-tuning, the tolerances of the support plate 2 in the horizontal and vertical directions can be strictly controlled within the design requirements, avoiding the cumulative error of multiple support plates 2 and improving the overall installation quality of the offshore wind power ATP airtight platform. Simultaneously, the method has a clear process and simple operation steps, reducing reliance on the technical skills of construction personnel, which helps ensure consistent construction quality. Furthermore, the device can be disassembled and recycled after installation, reducing material waste and construction costs.

[0058] In some embodiments, in step S1, the connecting base 3 is spot-welded to the column 1 of the offshore wind power ATP airtight platform via a panel 31, and the panel 31 is symmetrically arranged on both sides of the column 1. It should be noted that the connecting base 3 is spot-welded to the column via the panel 31, and the panel 31 is symmetrically arranged on both sides of the column. During the fixing process, the installation area of ​​the panel 31 is first marked on the column according to the design position. Then, the two panels 31 are respectively attached to the marked areas on both sides of the column, and spot welding is used to connect the panel 31 to the column. The number and distribution of spot welds are determined to ensure that the panel 31 does not shift or deform during adjustment, while controlling the spot weld strength to ensure that the panel 31 and the entire connecting base 3 can be easily removed after subsequent installation. The panels 31 are symmetrically arranged on both sides of the column, which makes the force on the connecting base 3 on the column more balanced, avoiding the tilting of the base caused by fixing on one side, thus ensuring that the installation benchmark of the adjustment component is in a horizontal state, laying the foundation for the precise adjustment of the support plate 2 later. The spot welding fixing method not only simplifies the fixing operation and reduces the construction difficulty compared with full welding, but also avoids excessive damage to the surface of the column and protects the structural integrity of the column. At the same time, the strength of spot welding is controllable, which can meet the stability requirements of the base during installation and adjustment, and facilitates the subsequent disassembly and recycling of the device, improving the reuse rate of the device and reducing construction costs.

[0059] In some embodiments, in step S4, the horizontal fine-tuning is achieved by rotating the horizontal adjustment components on the left and right sides, and the vertical fine-tuning is achieved by rotating the vertical adjustment components at the four bottom corners. It should be noted that the fine-tuning method of the support plate 2 is specifically as follows: horizontal fine-tuning is achieved by rotating the horizontal adjustment components on the left and right sides, and vertical fine-tuning is achieved by rotating the vertical adjustment components at the four bottom corners. When the total station measurement shows a horizontal deviation in support plate 2, if support plate 2 is biased to the left, rotate the screw 41 of the right horizontal adjustment component to push support plate 2 to the right. If it is biased to the right, rotate the screw 41 of the left horizontal adjustment component to push support plate 2 to the left until the horizontal deviation is eliminated. When the measurement shows a vertical deviation or insufficient levelness, if the actual height of a corner is lower than the design height, rotate the screw 41 of the vertical adjustment component in that corner to push support plate 2 upward. If the height of a corner is too high, rotate the corresponding screw 41 in the opposite direction. Adjust the height of support plate 2 by cooperating with the screws 41 in other corners until both the vertical deviation and levelness meet the requirements. By assigning different adjustment components to the horizontal and vertical fine-tuning directions, the fine-tuning operation becomes clearly targeted, avoiding blind adjustment and reducing the difficulty of operation. Even construction workers with average technical skills can quickly master the adjustment method, which helps improve construction efficiency. Horizontal adjustment is achieved through the cooperation of the horizontal adjustment components on the left and right sides, which can accurately control the horizontal displacement of the support plate 2 and avoid over-adjustment. Vertical adjustment is achieved through the cooperation of the four vertical adjustment components at the bottom corners, which can not only adjust the overall height of the support plate 2, but also calibrate the local levelness, effectively solving the problem of difficulty in balancing height and levelness in traditional adjustment methods, and further improving the installation and positioning accuracy of the support plate 2.

[0060] In some embodiments, in step S4, the measurement and fine-tuning steps are repeated multiple times until the horizontal and vertical tolerances of the support plate 2 do not exceed ±2mm. It should be noted that the precision control method for fine-tuning specifically involves repeatedly measuring and fine-tuning until the horizontal and vertical tolerances of the support plate 2 do not exceed ±2mm. During the fine-tuning process, the initial actual coordinates of the support plate 2 are first measured using a total station to obtain the deviation value and perform the first fine-tuning. After the fine-tuning is completed, the current coordinates of the support plate 2 are measured again using a total station to determine if the deviation is within ±2mm. If the deviation exceeds the range, a second fine-tuning is performed based on the new deviation value. This measurement and fine-tuning cycle is repeated, and the deviation is verified using a total station after each fine-tuning until the final measurement results show that the horizontal and vertical tolerances of the support plate 2 do not exceed ±2mm, at which point the fine-tuning stops. Through repeated measurements and fine-tuning cycles, the positional deviation of support plate 2 can be gradually reduced, avoiding the accumulation of errors that may occur in a single fine-tuning. This ensures that the final installation accuracy of support plate 2 strictly meets the design requirement of ±2mm tolerance, effectively avoiding subsequent platform assembly problems caused by insufficient accuracy, and improving the structural safety and performance of the offshore wind power ATP airtight platform. At the same time, multiple measurements by the total station can monitor the fine-tuning effect in real time, providing construction personnel with accurate adjustment basis, avoiding the time waste caused by blind fine-tuning, and achieving a balance between precision and efficiency while ensuring accuracy.

[0061] In some embodiments, after step S5 is completed, the installation positioning device is removed and can be reused. It should be noted that the device is handled after installation, specifically after step S5, i.e., after the support plate 2 is spot-welded to the column, the installation positioning device is removed and can be reused. During removal, firstly, the weld points between the panel 31 connecting the base 3 and the column are broken using tools, separating the panel 31 from the column. Then, the adjusting parts 4 on the base plate 32 and ear plate 33 are disassembled sequentially. The adjusting parts of the connecting base 3 and the adjusting components are collected separately. The disassembled parts are cleaned to remove surface dust, rust, and other impurities. The threads of the screws 41 and nuts 42 are checked for integrity, and the panel 31, base plate 32, and ear plate 33 are checked for deformation. Damaged or severely worn parts are replaced, while intact parts are kept for future use in the installation and positioning of other offshore wind power ATP airtight platform support plates. After installation, the device can be dismantled and reused, which can significantly reduce the one-time investment cost of the device and avoid the problem of material waste caused by the inability to recycle traditional special positioning tools after use, which is in line with the construction concept of energy conservation and environmental protection. Cleaning and inspecting the dismantled device components can promptly identify and replace damaged parts, ensuring the reliability and adjustment accuracy of the device in subsequent use and extending the overall service life of the device. In addition, the reuse of the device eliminates the need to remake positioning components before each installation, shortens the construction preparation time, further improves the overall construction efficiency, and reduces the construction cost of offshore wind power ATP airtight platforms.

[0062] To provide a clearer understanding of the invention, the invention is further described below:

[0063] The offshore wind power ATP airtight platform support plate installation and positioning device proposed in this invention includes a connecting base 3 and an adjustment component, the specific structure of which is as follows:

[0064] Connecting base 3: Used to establish a detachable connection with the column 1 of the offshore wind power ATP airtight platform, providing an installation base for the adjustment components. The connecting base 3 consists of a panel 31, a base plate 32, and ear plates 33. The panel 31 is made of Q235 steel with a thickness of 15mm and is symmetrically fixed to both sides of the column by spot welding, ensuring connection stability and facilitating subsequent disassembly and recycling. The base plate 32 is also made of Q235 steel with a thickness of 10mm. It is fixed to the outside of the panel 31 and has pre-set opening positions according to the dimensions of the support plate 2 to ensure smooth movement of the adjustment components 4. The ear plates 33 are 10mm thick and welded to the base plate 32 at the bottom, forming the mounting carrier for the adjustment components 4.

[0065] Adjustment Components: Their core function is to enable multi-dimensional fine-tuning of the support plate 2. They include multiple adjustment components 4, each employing a screw 41 and nut 42 mating structure. Nuts 42 are welded to one side of the through holes on both the base plate 32 and the ear plate 33. Screws 41 are threadedly connected to nuts 42, with one end of the screw 41 extending out of the through hole to abut against the support plate 2. The adjustment components are divided into horizontal and vertical adjustment components. Four sets of horizontal adjustment components are symmetrically installed on the ear plates 33 on the left and right sides of the support plate 2 to adjust its horizontal position. Four sets of vertical adjustment components are installed on the base plates 32 at the four corners of the bottom of the support plate 2 to adjust its vertical height. M16 screws are preferred to ensure force stability and adjustment accuracy during the adjustment process.

[0066] This invention also provides a method for installing and positioning a support plate for an offshore wind power ATP (Automatic Train Protection) airtight platform, using the aforementioned installation and positioning device, with the following specific steps:

[0067] S1: Fixing the base 3. The panel 31 is symmetrically fixed to the preset position of the column 1 of the offshore wind power ATP airtight platform by spot welding. The spot welding strength is sufficient to ensure the stability of the base and avoid displacement of the base during subsequent adjustment.

[0068] S2: Placement of support plate 2. Place the support plate 2 to be installed on the end of the screw 41 of the vertical adjustment component, so that the bottom of the support plate 2 is fully in contact with the four sets of vertical adjustment components, and at the same time ensure that the end of the screw 41 of the horizontal adjustment component is in contact with the left and right sides of the support plate 2, in preparation for subsequent fine adjustment.

[0069] S3: Coordinate Measurement. Accurately measure the actual installation coordinates of support plate 2 using a total station, and record the deviations of its horizontal and vertical directions from the design coordinates.

[0070] S4: Precision Fine-tuning. Based on the deviation data measured by the total station, adjust the corresponding adjustment components accordingly: horizontal deviations are corrected by tightening or loosening the horizontal adjustment components on the left and right sides, and vertical deviations are calibrated by adjusting the vertical adjustment components at the four corners of the bottom. During the fine-tuning process, the measurement and adjustment steps can be repeated multiple times until the horizontal and vertical tolerances of the support plate 2 do not exceed ±2mm, meeting the design requirements.

[0071] S5: Fixing and Removing. Spot weld the finely adjusted support plate 2 to the column to secure it, completing the installation and positioning. After the welding of support plate 2 to the column is completed, remove the connecting base 3 and the adjusting assembly. This device can be recycled and reused for subsequent installation work.

[0072] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0073] In this embodiment, the parameters of each component of the installation positioning device are as follows: the size of the panel 31 is adapted to the diameter of the column, typically with a width of 125mm and a length of 330mm; the diameter of the opening of the base plate 32 is slightly larger than the outer diameter of the M16 screw 41 to ensure that the screw 41 can be rotated smoothly; the position of the through hole of the ear plate 33 corresponds to the side position of the support plate 2 to ensure that the horizontal adjustment component can effectively act on the support plate 2.

[0074] During installation and positioning, in step S1, when spot welding the fixing, attention must be paid to the fit between panel 31 and the column to avoid gaps that could cause the base to tilt. In step S2, the support plate 2 must be placed horizontally to avoid excessive initial placement deviations that would increase the difficulty of fine-tuning. In step S3, the total station measurement requires multiple calibrations to ensure the accuracy of the measurement data. In step S4, fine-tuning adopts a "small-amplitude, multiple adjustments" method, with each rotation of screw 41 not exceeding a certain angle. To avoid over-adjustment, fine-tune and measure again to confirm the deviation until it meets the tolerance requirements; the spot welding fixation in step S5 requires setting weld points at the four corners and the middle of the support plate 2 to ensure the connection stability between the support plate 2 and the column 1 of the offshore wind power ATP airtight platform. The device should be removed after the welding has cooled down to avoid affecting the welding quality during the removal process.

[0075] In this embodiment, the screws 41 and nuts 42 of the adjusting component are treated with rust prevention to adapt to the humid and salty spray environment of offshore wind power and extend the service life of the device. After the device is removed, the screws 41 and nuts 42 can be cleaned and maintained for easy use next time.

[0076] The technical solution of the present invention has the following advantages over the prior art:

[0077] Significantly improved positioning accuracy: Small-scale movement adjustment is achieved through the threaded engagement of screws and nuts. Combined with the multi-dimensional layout of four sets of horizontal adjustment components and four sets of vertical adjustment components, positional deviations can be accurately corrected, ensuring that the horizontal and vertical tolerances of the support plate are controlled within ±2mm, effectively avoiding cumulative errors.

[0078] The operation process is simplified and efficient: no complicated auxiliary tools are required, and fine-tuning can be completed simply by turning the screws. This replaces the traditional method of repeated disassembly and re-welding, which greatly shortens the installation time and improves construction efficiency.

[0079] Significant cost control results: The device is made of Q235 standard steel, and the parts have a simple structure. They can be made from standard parts or through simple processing, resulting in low manufacturing costs. At the same time, the device can be disassembled, recycled, and reused, reducing material waste, and the precise positioning reduces rework costs.

[0080] High adaptability: The opening position of the base plate can be flexibly adjusted according to the support plate of different specifications, which is suitable for the installation of support plates of various models of offshore wind power ATP airtight platforms, and has strong versatility.

[0081] The technical solutions provided by the embodiments of the present invention have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of the present invention. The descriptions of the embodiments above are only for helping to understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
