Description

Technical Field

[0001] The present invention relates to the technical field of flange installation, and in particular to an auxiliary installation device and method for an offshore wind power flange. Background Art

[0002] Flange, also known as flange flange or flange, is a part that connects shafts to each other and is used to connect pipe ends. When flanges are used to connect two pipes, in order to ensure the accuracy of the docking between the flanges, it is necessary to ensure the concentricity of the two flanges to prevent deviation between the two pipes after docking.

[0003] However, the existing flange docking installation is mostly carried out by setting a fixing mechanism on the flange with a device similar to a crane on the hull, and then moving the flange by a lifting rope set on the fixing mechanism. However, the lifting rope is very likely to shake due to reasons such as sea breeze, which can easily pose a huge threat to the safety of the workers.

[0018] An offshore wind turbine flange auxiliary installation device, the use steps of the offshore wind turbine flange auxiliary installation device are as follows:

[0019] Step 1: First, weld the main body 1 and the wind power pipe on the base, then move the device to a suitable position, and then stand up the main body 2. At this time, start the two cylinders 2, and the two fixing blocks move closer to each other to fix the outer wall of the wind power pipe at the lower end;

[0020] Step 2: Pass the lower end of the support member through the lower end of the body placed on the two protrusions, and then start the motor 1 in the forward direction. The motor 1 drives the gear 2 to rotate, and then drives the two abutment plates to move out of the sleeve 2 through the rack 2 to fix the top of the wind power pipe above. As the motor 1 starts, the cylinder begins to rotate, and then drives the drive ring to rotate through the connecting frame 1. At this time, the gear 1 rotates, driving the rotating shaft 1 to rotate, and the multiple support plates are rotated out to support and fix the lower end of the body 1;

[0021] Step three, after the body one and the wind power pipe on the body one are fixed, move them to the top of the body two, move the body one toward the welded body two, until the body one moves into the detection range of the visual detector, and then the visual detector starts to detect. When the holes of the body one and the body two are aligned, the visual detector detects the image on the detection plate, and the welding machine is used to perform on-site welding on the connection between the upper end of the body two and the upper end of the wind power pipe. After the welding is completed, step four is implemented. When the visual detector does not detect the image on the detection plate, the controller controls the cylinder three to clamp the body two through the clamping plate, and then the motor two is started to rotate the body two until the holes of the body one and the body two are aligned. After alignment, the welding machine is used to perform on-site welding on the connection between the upper end of the body two and the upper end of the wind power pipe. After the welding is completed, the following step four is implemented;

[0022] Step 4: Start motor 1 in reverse, and multiple support plates and abutment plates are moved back to their original positions, and the main body 1 is no longer fixed. At this time, the main body 1 slides downward along the two limit frames 2 under the limiting action of the two limit frames 2 until the lower end surface of the main body 1 is in contact with the upper end surface of the main body 2, completing the fixed installation of the two main bodies 1 and 2.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The stable structure composed of the support parts, reinforcement parts and linkage parts of the device of the present invention can effectively resist the interference of external factors such as sea breeze and waves during the installation process. Even in harsh marine environments, it can ensure the smooth progress of the flange installation process, reducing the probability of installation accidents caused by external environmental factors. For example, the stable support structure can prevent the device from tipping over or displacing under the action of wind and waves, thereby avoiding a series of safety accidents caused by this, and providing a safer and more reliable working environment for offshore wind power flange installation operations. Compared with the traditional flange lifting method, the lifting rope is easily affected by the sea breeze and shakes, and the operator faces greater safety risks when docking the flange. The device of the present invention greatly reduces the exposure time and operation frequency of personnel in dangerous areas through an automated installation process. The operator only needs to start the device in a relatively safe position and monitor the installation process, effectively reducing the risk of casualties caused by accidents such as lifting rope shaking and flange slipping, and ensuring the life safety of construction personnel.

[0025] The design of the entire device of the present invention is highly automated, and the various components work together through a precise linkage mechanism. For example, during the installation process, it is only necessary to start motor one and cylinder two to automatically complete a series of operations such as fixing the main body one and its internal wind power pipe, unfolding the support parts, and positioning the reinforcement parts. There is no need for a lot of manual intervention and complex manual adjustment. The cooperation between the visual detection mechanism and the controller realizes real-time monitoring and automatic error correction of the installation process, which greatly shortens the adjustment time during the installation process. Compared with the traditional lifting method, the present device significantly improves the installation speed of offshore wind power flanges, can complete more installation tasks in a shorter time, effectively shortens the construction period of offshore wind power projects, and improves the overall economic benefits of the project. The support parts and reinforcement parts in the installation assembly cooperate with each other to provide extremely stable support and fixing conditions for flange installation. Multiple equidistantly distributed support plates can accurately unfold and support the lower end of the main body one under the action of the linkage parts. At the same time, the back plate of the reinforcement part can firmly resist the top of the wind power pipe. This all-round stability The support structure effectively prevents the flange from being displaced or shaken due to external forces during the installation process, further ensuring the accuracy of the flange installation, making the pipeline connection more stable and reliable, and improving the operational stability of the entire offshore wind power system. The offshore wind power flange auxiliary installation device of the present invention is equipped with a visual detection mechanism. Through the accurate recognition of the detection plate image by the visual detector, the relative position of the main body one and the main body two can be monitored in real time. Once a deviation is found in the hole position of the main body one and the main body two, the controller can quickly control the operation of the motor two and the cylinder three, and use the splint to accurately adjust the main body two to ensure that the concentricity of the two flanges is within a very small error range. This automated detection and adjustment mechanism greatly improves the accuracy of flange docking, effectively avoids errors that may be caused by manual measurement and adjustment, thereby further increasing the safety of operators during operation, thereby ensuring the quality of offshore wind power pipeline connections, reducing pipeline leakage, stress concentration and other problems caused by insufficient installation accuracy, extending the service life of offshore wind power facilities, and reducing subsequent maintenance costs.

[0026] The design of the mobile assembly of the present invention makes the movement and positioning of the device on the offshore platform extremely convenient. The multiple mobile wheels at the lower end of the base are driven in coordination by motor three and motor four to achieve precise steering and position adjustment. When switching between different wind power pipeline installation positions, the device can be moved into place quickly and accurately, reducing time waste during equipment transfer. At the same time, the adjustment mechanism can flexibly adjust the height and angle of the installation assembly, so that it can quickly adapt to different installation scenarios and operation requirements, further improving the efficiency of the installation operation and avoiding installation delays caused by insufficient equipment adaptability.

The rotation of the driving ring 34 drives the rack 33 to move, thereby rotating the rotating shaft 31, thereby rotating the support plates 30 to the lower end of the body 1, thereby achieving the support function of the body 1;

[0045] The reinforcement member 4 includes a second gear 40, two symmetrically distributed second racks 41 meshing with the second gear 40, and a support plate 42 fixedly connected to one end of the second rack 41. The ends of the two second racks 41 close to the support plate 42 are L-shaped. A second rotating shaft 43 is fixedly connected to the inner wall of the second gear 40. One end of the second rotating shaft 43 is fixedly connected to the output shaft of the first motor 44. When the first motor 44 is started, it can drive the second gear 40 to rotate, so that the second rack 41 drives the support plate 42 to move out of the second sleeve 51, thereby reinforcing the top of the wind power pipe in the body 1;

[0046] And a moving component 7, which is used to move the installation component, and the moving component 7 is arranged at one end of the main body 1 and the main body 2 2.

[0047] The linkage member 5 includes a sleeve 1 50 fixedly mounted on the upper end of the driving ring 34, a sleeve 2 51 movably connected to the upper end of the sleeve 1 50, a cylinder 1 52 fixedly mounted on the lower end of the rotating shaft 2 43, a connecting frame 1 53 fixedly connected to the lower end of the cylinder 1 52, and a reinforcement frame 54. The lower end of the connecting frame 1 53 is fixedly connected to the upper end of the driving ring 34 to drive the driving ring 34 to rotate. The reinforcement frame 54 is slidably connected to the inner wall of the sleeve 2 51. The lower end of the reinforcement frame 54 is fixedly connected to a connecting column. The lower end of the connecting column is fixedly connected to a connecting frame 2 55. The side wall of the connecting frame 2 55 is slidably connected to the inner wall of the driving ring 34. The lower end of the connecting frame 2 55 is fixedly connected to a reinforcement plate 56. The plurality of support plates 30 movably Located at the upper end of the reinforcement plate 56, the linkage member 5 can form a linkage working mechanism between the support member 3 and the reinforcement member 4. During use, when it is necessary to fix the top of the wind power pipe, start the motor 1 44, and the output shaft of the motor 1 44 drives the rotating shaft 2 43 to rotate. Since the gear 2 40 is fixedly connected to the rotating shaft 2 43, the gear 2 40 rotates synchronously therewith, and the rotating gear 2 40 interacts with the two symmetrically distributed and meshing racks 2 41, so that the two racks 2 41 move relative to or opposite to each other along the radial direction of the gear 2 40 depending on the rotation direction of the motor 1 44. Because one end of the rack 2 41 is fixedly connected to the abutment plate 42, the abutment plate 42 moves out of the sleeve 2 51 as the rack 2 41 moves, gradually approaching the top of the wind power pipe until the abutment plate 42 fits tightly on the top of the wind power pipe to complete the fixing operation on the top of the wind power pipe.

The rotating shaft 1 31 causes the support plate 30 connected thereto to rotate around the axis of the shaft 1 31 and gradually rotate out from the initial retracted position to support and fix the lower end of the body 1. When the flange is installed, the device needs to be reset for the next use or movement of the device. At this time, the motor 1 44 is started in the reverse direction, and the motor 1 44 drives the shaft 2 43 to reverse, and the gear 2 40 also reverses, so that the rack 2 41 drives the support plate 42 to move into the sleeve 2 51 and return to the initial position. At the same time, the cylinder 1 52 rotates in the reverse direction, driving the connecting frame 1 53 to reverse, and the driving ring 34 also reverses.
