Description

Technical Field

[0001] The utility model relates to the technical field of offshore wind power, and particularly relates to a structure of an offshore wind power construction auxiliary platform. Background Technique

[0002] The offshore wind power construction auxiliary platform is mainly used for operations such as the construction of the fan foundation, the installation and maintenance of the wind power tower barrel, tower frame, nacelle, hub, and blade. With the continuous development of offshore wind power technology, the performance requirements for the operation platform are also getting higher and higher. Among them, the lifting speed, as one of the important indicators to measure the platform performance, has received extensive attention.

[0003] However, the existing operation platforms generally have the following problems in terms of lifting speed: 1. Insufficient efficiency of the lifting system: For the traditional stepping lifting system, its lifting speed is usually about 12m / h, which cannot meet the requirements of modern offshore wind power operations for high efficiency; 2. Problems with the hydraulic system: The slow lifting speed of the aerial work platform may be caused by reasons such as the aging, leakage, and blockage of the hydraulic system. For example, the hydraulic oil may deteriorate or contain impurities after long-term use, resulting in a reduction in the flow rate of the hydraulic system; the blockage of the hydraulic pipeline or hydraulic valve may also affect the lifting speed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a structure of an offshore wind power construction auxiliary platform, and a combined lifting system can be used to realize the rapid lifting of the operation platform and improve its lifting efficiency.

[0005] In order to solve the above technical problems, the utility model provides the following technical solution: A structure of an offshore wind power construction auxiliary platform, including an operation platform that can perform lifting movement on a pile column. The operation platform is connected to the pile column through a combined lifting mechanism for lifting the operation platform. The combined lifting mechanism includes a long-distance adjustment component and a short-distance adjustment component. The long-distance adjustment component and the short-distance adjustment component cooperate with each other through a linkage mechanism to improve the efficiency of the conversion process, avoid problems such as long time consumption caused by converting to driving the short-distance adjustment component after the driving of the long-distance adjustment component ends, and improve the efficiency of the conversion process;

[0006] The long-distance adjustment assembly includes a first hinge rod and a second hinge rod that are hinged to each other. The first hinge rod and the second hinge rod form an X-shaped structure, and their hinge point is located at the center of the X-shaped structure. The sides of the first hinge rod and the second hinge rod close to the operation platform are respectively located in positioning bins installed on the operation platform. Electric sliding rails are provided in the positioning bins. The bottom end of the first hinge rod is slidably connected to the electric sliding rail through a slider. The bottom end of the second hinge rod is rotatably installed in the positioning bin through a rotating shaft. A fixed platform is installed on the pile column above the operation platform. The top ends of the first hinge rod and the second hinge rod are respectively hinged to the bottom of the fixed platform. When the electric sliding rail drives the slider to displace, the included angle formed by the first hinge rod and the second hinge rod can quickly become larger or smaller, thereby realizing the rapid lifting and lowering of the operation platform. When the slider moves towards the position close to the second hinge rod, the included angle becomes smaller, and the fixed platform quickly rises under the action of the first hinge rod and the second hinge rod. When the slider moves away from the position of the second hinge rod, the included angle becomes larger, and the fixed platform quickly descends under the action of the first hinge rod and the second hinge rod.

[0007] Further, the short-distance adjustment assembly is installed on the fixed platform. The short-distance adjustment assembly includes a plurality of frames circumferentially distributed around the pile column. A plurality of rolling wheels for abutting against the pile column are installed on the frames. After the long-distance adjustment assembly adjusts the lifting range of the operation platform in a large range, the height of the operation platform can be finely adjusted through the rolling wheels to ensure that the height of the operation platform can reach the specified position.

[0008] Further, a sliding groove is installed on the frame. The rolling wheel is connected to the frame through an adjustment frame. The adjustment frame is slidably arranged on the sliding groove on the frame. A driving motor for driving the rolling wheel to rotate is provided on the adjustment frame. By setting the adjustment frame, the distance between two adjacent rolling wheels can be adjusted, so as to cope with the problem that the part of the pile column above the fixed platform is too short.

[0009] Further, a locking block is installed on the adjustment frame. A plurality of positioning holes are arranged at intervals on the frame. The position of the displaced adjustment frame and rolling wheel is locked by the cooperation of the locking block and the positioning holes to ensure the stability of the rolling wheel during the rolling process of abutting against the pile column.

[0010] Further, the linkage mechanism includes a driving gear installed in the fixed platform. An upper gear rack meshing with it is installed above the driving gear. A lower gear rack meshing with it is installed below the driving gear. The driving gear is driven by a built-in motor. The bottom of the frame extends into the fixed platform and is fixedly connected to the upper gear rack. A clamping member for clamping the pile column is provided below the lower gear rack close to the pile column side.

[0011] Further, the upper gear bar and the lower gear bar are parallel to each other. In the working state of the long-distance adjustment assembly, the lower gear bar is closer to the pile column than the upper gear bar, and the clamping member on the lower gear bar can clamp the pile column. When the long-distance adjustment assembly is switched to the short-distance adjustment assembly, the driving gear rotates to move the lower gear bar away from the pile column and the upper gear bar closer to the pile column, so that the rolling wheels on the frame body abut against the pile column for micro adjustment.

[0012] Further, the clamping member is in the shape of a long strip-like arc structure and can cooperate with the surface of the pile column for clamping.

[0013] Further, two sets of long-distance adjustment assemblies are provided and are respectively located on opposite sides of the pile column. Four sets of short-distance adjustment assemblies are provided and are circumferentially and equidistantly distributed outside the pile column to improve the support effect on the pile column.

[0014] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0015] 1. The present utility model has the capabilities of efficient conversion and rapid lifting. Through the innovative combined lifting mechanism, the efficient collaborative work of the long-distance and short-distance adjustment assemblies is realized, significantly improving the conversion efficiency of the operation platform at different height adjustment stages. The long-distance adjustment assembly adopts an X-shaped articulated rod structure combined with an electric slide rail, which can greatly change the height of the operation platform in a short time, meet the requirement of rapid lifting, and reduce the time-consuming problem that may exist in the traditional conversion process.

[0016] 2. The introduction of the short-distance adjustment assembly in the present utility model, especially through the design of the frame body and rolling wheels distributed around the pile column, provides the operation platform with the ability of fine height adjustment, ensuring that the operation platform can accurately reach the designated position. This design not only enhances the flexibility of platform operation but also can effectively meet the installation or maintenance requirements under various complex sea conditions, improving the operation accuracy and safety.

[0017] 3. Through the design of the adjustment frame, sliding groove, driving motor, and the cooperation of the lock block and positioning hole in the present utility model, the platform can not only be flexibly adjusted to adapt to pile columns of different diameters but also greatly enhance the stability during the operation. The cooperation of the lock block and positioning hole ensures the stable rolling of the rolling wheels when abutting against the pile column, preventing slipping, improving the safety performance of the overall system. At the same time, the arc design of the clamping member optimizes the contact surface with the pile column, further enhancing the clamping stability, reducing the potential risks during the operation, and ensuring the continuity and reliability of the operation.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a structure of an offshore wind power construction auxiliary platform, including an operation platform 1 that can perform lifting movement on a pile column 101. The operation platform 1 is connected to the pile column 101 through a combined lifting mechanism for lifting the operation platform 1. The combined lifting mechanism includes a long-distance adjustment component 2 and a short-distance adjustment component 3. The long-distance adjustment component 2 and the short-distance adjustment component 3 cooperate with each other through a linkage mechanism 4 to improve the efficiency of the conversion process, avoid problems such as long time consumption caused by converting to driving the short-distance adjustment component 3 after the driving of the long-distance adjustment component 2 ends, and improve the efficiency of the conversion process;

[0026] The long-distance adjustment assembly 2 includes a first hinge rod 5 and a second hinge rod 6 that are hinged to each other. The first hinge rod 5 and the second hinge rod 6 form an X-shaped structure, and their hinge point is located at the center of the X-shaped structure. The sides of the first hinge rod 5 and the second hinge rod 6 close to the working platform 1 are respectively located in the positioning bins 7 installed on the working platform 1. An electric slide rail 8 is provided in the positioning bin 7. The bottom end of the first hinge rod 5 is slidably connected to the electric slide rail 8 through a slider 9. The bottom end of the second hinge rod 6 is rotatably installed in the positioning bin 7 through a rotating shaft. A fixed platform 10 is installed on the pile column 101 above the working platform 1. The top ends of the first hinge rod 5 and the second hinge rod 6 are respectively hinged to the bottom of the fixed platform 10. When the electric slide rail 8 drives the slider 9 to displace, the included angle formed by the first hinge rod 5 and the second hinge rod 6 can quickly become larger or smaller, so as to realize the rapid lifting of the working platform 1. When the slider 9 moves towards the position close to the second hinge rod 6, the included angle becomes smaller, and the fixed platform 10 quickly rises under the action of the first hinge rod 5 and the second hinge rod 6. When the slider 9 moves away from the position of the second hinge rod 6, the included angle becomes larger, and the fixed platform 10 quickly descends under the action of the first hinge rod 5 and the second hinge rod 6.

[0027] Further, the short-distance adjustment assembly 3 is installed on the fixed platform 10. The short-distance adjustment assembly 3 includes a plurality of frames 11 distributed circumferentially around the pile column 101. A plurality of rolling wheels 12 for abutting against the pile column 101 are installed on the frames 11. After the long-distance adjustment assembly 2 widely adjusts the lifting range of the working platform 1, the height of the working platform 1 can be finely adjusted through the rolling wheels 12 to ensure that the height of the working platform 1 can reach the designated position.

[0028] Further, a sliding groove is installed on the frame 11. The rolling wheel 12 is connected to the frame 11 through an adjusting frame 111. The adjusting frame 111 is slidably arranged on the sliding groove on the frame 11. A driving motor 13 for driving the rolling wheel 12 to rotate is provided on the adjusting frame 111. By arranging the adjusting frame 111, the distance between two adjacent rolling wheels 12 can be adjusted to cope with the problem that the part of the pile column 101 above the fixed platform 10 is too short.

[0029] Further, a locking block 14 is installed on the adjusting frame 111. A plurality of positioning holes are arranged at intervals on the frame 11. The position of the displaced adjusting frame 111 and the rolling wheel 12 is locked by the cooperation of the locking block 14 and the positioning holes to ensure the stability of the rolling wheel 12 during the rolling process of abutting against the pile column 101.

[0030] Further, the linkage mechanism 4 includes a driving gear 401 installed inside the fixed platform 10. Above the driving gear 401, an upper gear rack 402 meshing with it is installed. Below the driving gear 401, a lower gear rack 403 meshing with it is installed. The driving gear 401 is driven by a built-in motor. The bottom of the frame 11 extends into the fixed platform 10 and is fixedly connected to the upper gear rack 402. Below the lower gear rack 403 near one side of the pile column 101, a clamping member 404 for clamping the pile column 101 is provided.

[0031] Further, the upper gear rack 402 and the lower gear rack 403 are parallel to each other. In the working state of the long-distance adjustment component 2, the lower gear rack 403 is closer to the pile column 101 than the upper gear rack 402, and the clamping member 404 on the lower gear rack 403 can clamp the pile column 101. When the long-distance adjustment component 2 is switched to the short-distance adjustment component 3, the driving gear 401 rotates to respectively move the lower gear rack 403 away from the pile column 101 and the upper gear rack 402 closer to the pile column 101, so that the rolling wheels 12 on the frame 11 abut against the pile column 101 for micro adjustment.

[0032] Further, the clamping member 404 is in a long strip-shaped arc structure and can cooperate with the surface of the pile column 101 for clamping.

[0033] Further, two sets of long-distance adjustment components 2 are provided and are respectively located on opposite sides of the pile column 101. Four sets of short-distance adjustment components 3 are provided and are circumferentially and equidistantly distributed outside the pile column 101 to improve the support effect on the pile column 101.

[0034] Working principle: The working principle of this self-elevating offshore wind power operation platform is based on the coordinated operation of the combined lifting mechanism. First, the long-distance adjustment component 2 interacts with the electric slide rail 8 through an X-shaped hinged rod structure (composed of the first hinged rod 5 and the second hinged rod 6) to achieve the rapid and large-scale lifting of the operation platform 1. When the electric slide rail 8 pushes the slider 9 to move along the first hinged rod 5, the included angle between the hinged rods changes accordingly, driving the fixed platform 10 and the operation platform 1 to rise or fall rapidly. This process is particularly suitable for situations where it is necessary to quickly adjust to a roughly height range.

[0035] Subsequently, when fine adjustment of the height of the operation platform 1 is required, the short-distance adjustment component 3 intervenes in the work. This component includes a frame 11 and rolling wheels 12 distributed around the pile column 101. Through the cooperation of the adjusting frame 111 and the driving motor 13, not only can the contact point between the rolling wheels 12 and the pile column 101 be finely adjusted, but also the distance between adjacent rolling wheels 12 can be adjusted to adapt to pile columns 101 with different diameters or solve the problem of local shortness. The locking mechanism (lock block 14 and positioning hole) ensures the stability and safety after adjustment.

[0036] During the conversion of the long-distance and short-distance adjustment assembly 3, the linkage mechanism 4 plays a key role. The driving gear 401, through its cooperation with the upper and lower gear racks 403 and the clamping member 404 on the lower gear rack 403, ensures the smooth and efficient conversion. Especially when converting from long-distance adjustment to short-distance adjustment, the rotation of the driving gear 401 causes the lower gear rack 403 to move away from the pile column 101, while the upper gear rack 402 moves closer to the pile column 101, prompting the rolling wheels 12 on the frame 11 to closely fit the surface of the pile column 101, achieving precise height control.
