Description

Technical Field

[0001] This utility model relates to the technical field of hoisting equipment for wind turbine installation, and in particular to a wind turbine installation frame machine. Background Technology

[0002] The main equipment of a wind power generation system is the wind turbine, which effectively converts wind energy into electrical energy. The wind turbine mainly includes a base tower, a nacelle, a hub, and multiple blades. The nacelle is rotatably mounted on top of the base tower, circumferentially around its circumference. The hub is cantilevered at the front end of the nacelle and is rotatably mounted around its central axis. The blades are connected to the hub via flanges and secured with bolts. The flange connection end of the hub has positioning holes, and the flange connection end of the blades has threaded positioning rods that pass through the positioning holes and are secured with bolts. Multiple blades are evenly spaced around the hub circumferentially. Generally, the hub's rotatable mounting around the central axis is used to adjust the blades' windward direction during power generation, and the blades' rotatable mounting around the central axis is used to adjust their windward angle.

[0003] Currently, there are two main methods for assembling wind turbines: the first is to assemble multiple blades on the ground to form a wind turbine, and then use a crane to lift and install the wind turbine onto the nacelle (which is located at the top of the foundation tower); the second is to install the hub onto the nacelle (which is located at the top of the foundation tower), and then use a crane to lift and install the blades one by one onto the hub. The first assembly method, where the blades and hub are joined on the ground, allows for good control of the assembly angle. However, due to the large size of the blades, the installation requires a large area and high terrain, and the entire rotor needs to be hoisted, placing high demands on the crane and boom. The second assembly method, in order to reduce wind load disturbances during the individual high-altitude hoisting and installation of blades, typically involves manipulating the boom to align the blade spanwise with the wind direction during hoisting and installation (reducing the cross-sectional area of ​​the blades under wind load and preventing blade tipping or excessive swaying). Simultaneously, the hub and nacelle are rotated for angle adaptation during assembly. However, in the existing technology, the tilt angle and relative height of the blades during hoisting and assembly cannot be finely adjusted. Precise insertion and positioning of the blades and hub are difficult to achieve in dead angles during boom swing or hub rotation, resulting in technical problems that make blade hoisting and assembly inconvenient.

[0004] In view of this, it is necessary to propose a wind power installation rack to solve or at least alleviate some of the above-mentioned defects. Utility Model Content

[0005] The main objective of this invention is to provide a wind power installation frame that aims to solve or at least partially solve the aforementioned technical problems.

[0006] To achieve the above objectives, this utility model provides a wind turbine installation frame, including a hook, slings, and a frame. The frame is suspended from the hook by the slings. The frame includes a frame body, a sling, extension rollers, and a sling adjustment mechanism. The frame body is frame-shaped, with extension rollers at both ends along its length. The extension rollers are located on the lower side of the frame body and are fixedly connected to it. Both sides of the extension rollers extend outward and outward to the width sidewall of the frame body. The sling adjustment mechanism and the sling are arranged correspondingly to the extension rollers. The first end of the sling adjustment mechanism is fixedly mounted on the frame body, and the second end of the sling is connected to the first end of the sling. The second end of the sling passes around the corresponding extension roller from the bottom of the frame body and is connected to the other side of the frame body. The first end of the sling moves upward or downward relative to the first end through the lifting or winding movement of the second end of the sling adjustment mechanism.

[0007] Furthermore, the extension roller includes a fixed mounting frame and a tensioning roller. The fixed mounting frame is located on the lower side of the frame and is fixedly connected to the frame. The two tensioning rollers are located opposite each other at the two ends of the fixed mounting frame in the width direction. The tensioning rollers are at least partially located outside the width direction side wall of the frame. The tensioning rollers are rotatably mounted on the fixed mounting frame. The second end of the sling is arranged to pass around the corresponding two tensioning rollers sequentially from the bottom of the frame.

[0008] Furthermore, the tensioning roller has a recessed roller groove in the middle, and the sling is housed in the roller groove.

[0009] Furthermore, the wind turbine installation frame also includes a locking and safety mechanism, which includes a fixed locking frame and a locking abutment head. The first end of the fixed locking frame is fixedly connected to the frame body, and the second end of the fixed locking frame is arranged to be cantilevered outward in the lateral direction. The fixed locking frame is provided with a locking through hole between the frame bodies for cooperating with the sling. The locking abutment head is fixedly installed at the first end of the sling and is located above the fixed locking frame. The transverse cross section of the locking abutment head is larger than the cross section of the locking through hole.

[0010] Furthermore, the locking support head includes locking blocks and locking bolts. The two locking blocks are spliced ​​together to clamp the sling and are fixedly connected by the locking bolts.

[0011] Furthermore, the belt adjustment mechanism includes a hydraulic lifting cylinder and a pulling plate. The hydraulic lifting cylinder is fixedly installed on the top surface of the frame along the height direction of the frame. The fixed end of the hydraulic lifting cylinder is fixedly connected to the frame. The lifting movable end of the hydraulic lifting cylinder is fixedly connected to the first end of the pulling plate. The second end of the pulling plate cantilevered outward and connected to the first end of the sling.

[0012] Furthermore, the belt adjustment mechanism includes a winch fixedly mounted on the top surface of the frame, with the first end of the winch fixedly connected to the frame and the winding end of the winch connected to the first end of the sling.

[0013] Furthermore, slings are connected to the four corners of the hanger, and the hanger is suspended from the hook by the four slings.

[0014] Furthermore, the frame includes a rectangular frame, reinforcing ribs, and connecting hooks. Multiple reinforcing ribs are arranged at intervals along the length of the rectangular frame. Connecting hooks are provided on both sides of the rectangular frame, and the connecting hooks are arranged near the corners of the rectangular frame.

[0015] Furthermore, multiple connecting hooks are arranged at intervals along the length of the rectangular frame.

[0016] This utility model also provides a wind power system, including a foundation tower, a nacelle, a hub, and blades. The nacelle is rotatably mounted on the top of the foundation tower around its circumference. The front end of the nacelle is cantilevered outward and has a hub arranged thereon. The hub is rotatably mounted around the central axis of the installation. The blades are connected to the hub via flanges and fixed with fastening bolts. The flange connection end of the hub has a positioning hole. The flange connection end of the blade is fixed with a threaded positioning rod, which passes through the positioning hole. Multiple blades are evenly spaced on the hub along its circumference. The blades are hoisted and assembled onto the hub using the aforementioned wind power installation frame.

[0017] Compared with the prior art, the wind turbine mounting frame provided by this utility model has the following beneficial effects:

[0018] The wind turbine installation frame provided by this utility model includes a hook, slings, and a frame. The frame is suspended from the hook by the slings. When assembling the blades one by one, the boom of the crane can hang the hook and lift the frame under the action of the slings. The frame includes a frame body, slings, extension rollers, and a belt adjustment mechanism. The extension rollers are located on the lower side of the frame body and are fixedly connected to the frame body. The two sides of the extension rollers extend outward and out of the wide side wall of the frame body. The belt adjustment mechanism, slings, and tension rollers are arranged correspondingly. Slings are arranged at both ends of the length of the frame body, and the slings are extended outside the frame body by the tensioning action of the extension rollers, which helps to avoid the belt adjustment mechanism. When the first end of the drive sling rises or falls, interference occurs between the sling and the frame. Simultaneously, the second end of the sling adjustment mechanism moves up or down relative to the first end, or rewinds, causing the first end of the sling to move upward or downward. The movement of the slings at both ends of the frame allows for fine-tuning of the lifting tilt and pitch angles of the suspended blades. Fine-tuning the lifting tilt angle during blade installation further reduces interference from crosswinds. During blade installation, fine-tuning the lifting tilt and pitch angles can avoid dead angles in the blade-hub assembly, facilitating blade lifting and assembly and improving the ease of operation.

[0029] The purpose, features, and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0030] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0033] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0034] Research has revealed that high-altitude hoisting and assembly of blades is a common method for assembling and installing wind turbines. Specifically, the first wind turbine blade is horizontally hoisted and installed at the hub. Then, the hub is rotated to hoist and assemble the second blade, and so on, until the third blade is hoisted and assembled. During the hoisting process, manipulating the boom to align the blade's spanwise direction with the windward direction effectively avoids interference from lateral winds caused by the large surface area of ​​the blade's windward side. However, existing methods do not consider further reducing wind load interference by adjusting the hoisting angle of the blade root (tip). During assembly, manipulating the boom minimizes wind load interference on the blade, and adjusting the rotation angle of the nacelle and hub to match the threaded positioning rod at the blade root position is employed. However, because the blades are assembled piece by piece, dead angles exist during the assembly and mating of the blades with the hub, making it difficult to position the blades and align them with the positioning holes on the hub, resulting in assembly inconvenience.

[0035] Please refer to the appendix. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 This utility model provides a wind turbine installation frame 100, including a hook 10, a sling 20, and a frame 30. The frame 30 is suspended from the hook 10 by the sling 20. The frame 30 includes a frame body 31, a sling 32, extension rollers 33, and a sling adjustment mechanism 34. The frame body 31 is frame-shaped, and extension rollers 33 are respectively provided at both ends of the frame body 31 along its length. The extension rollers 33 are located on the lower side of the frame body 31 and are fixedly connected to the frame body 31. The two sides of the extension rollers 33 extend outward and extend into the frame body 31. Outside the wide side wall, the belt adjustment mechanism 34 and the sling 32 are respectively arranged in correspondence with the extension roller 33. The first end of the belt adjustment mechanism 34 is fixed on the frame 31, and the second end of the belt adjustment mechanism 34 is connected to the first end of the sling 32. The second end of the sling passes around the corresponding extension roller 33 from the bottom of the frame 31 and is connected to the other side of the frame 31. The first end of the sling 32 moves up or down relative to the first end through the lifting or winding movement of the second end of the belt adjustment mechanism 34.

[0036] The wind turbine installation frame 100 provided by this utility model includes a hook 10, a sling 20, and a frame 30. The frame 30 is suspended from the hook 10 by the sling 20. When the blades are hoisted and assembled one by one, the boom of the crane can hang the hook 10 and lift the frame 30 under the action of the sling 20. The frame 30 includes a frame body 31, a sling 32, a tension roller 33, and a belt adjustment mechanism 34. The tension roller 33 is located on the lower side of the frame body 31 and is fixedly connected to the frame body 31. The two sides of the tension roller 33 extend outward and extend beyond the width side wall of the frame body 31. The belt adjustment mechanism 34, the sling 32, and the tension roller 332 are arranged correspondingly. The sling 32 is arranged at both ends of the length direction of the frame body 31, and the sling 32 is tensioned by the tension roller 33. Extending beyond the frame 31 helps avoid interference between the belt and the frame 31 when the belt adjustment mechanism 34 drives the first end of the sling 32 to rise or fall. Simultaneously, the second end of the belt adjustment mechanism 34 moves up or down relative to the first end, or retracts, causing the first end of the sling 32 to move upward or downward. The movement of the slings 32 at both ends of the frame 31 can drive the fine-tuning of the suspended blades to adjust the lifting tilt angle and lifting pitch angle. Fine-tuning the lifting tilt angle during blade lifting can further reduce the interference of crosswinds. During blade installation, fine-tuning the lifting tilt angle and lifting pitch angle can be used to avoid dead angles in the blade and hub insertion assembly, facilitating blade lifting and assembly and improving the ease of operation for blade lifting and assembly.

[0037] Please refer to this again. Figure 6 and Figure 7 Understandably, in this invention, the frame 31 has belts at both ends along its length. Each belt is adjusted and controlled by a corresponding belt adjustment mechanism 34. By simultaneously adjusting the belts at both ends, the lifting tilt angle of the blade (the angle from the leading edge to the trailing edge) can be finely adjusted. By adjusting the belt at one end, the lifting pitch angle of the blade (the angle from the blade tip to the blade root) can be finely adjusted. Optionally, the belt adjustment mechanism 34 can be a lifting adjustment mechanism or a winding mechanism, as long as the belt adjustment mechanism 34 drives the first end of the belt to rise or fall relative to the frame 31.

[0038] Furthermore, the extension roller 33 includes a fixed mounting frame 331 and tension rollers 332. The fixed mounting frame 331 is located on the lower side of the frame 31 and is fixedly connected to the frame 31. The two tension rollers 332 are arranged opposite each other at the two ends of the fixed mounting frame 331 in the width direction. The tension rollers 332 are at least partially located outside the width direction sidewall of the frame 31. The tension rollers 332 are rotatably mounted on the fixed mounting frame 331. The second end of the sling is arranged from the bottom of the frame 31 and passes around the corresponding two tension rollers 332 in sequence. In this utility model, the tension rollers 332 are arranged below the frame 31 and protrude from the width direction sidewall of the frame 31 through the fixed mounting frame 331, which can effectively tension the sling 32 to the outside of the frame 31 and avoid friction between the sling 32 and the frame 31 when it moves. At the same time, the symmetrical arrangement of the two tension rollers 332 can improve the stability during hoisting and assembly.

[0039] Furthermore, a recessed roller groove is arranged in the middle of the tension roller 332, and the sling is accommodated in the roller groove. Understandably, in this invention, the sling is at least partially accommodated in the roller groove, and the roller groove limits the sling to prevent it from sliding out of the tension roller 332 along its length. Optionally, the width of the sling is 5-25 cm.

[0040] Please refer to this again. Figure 2 Furthermore, the wind turbine mounting frame 100 also includes a locking safety mechanism 40, which includes a fixed locking frame 41 and a locking abutment head 42. The first end of the fixed locking frame 41 is fixedly connected to the frame body 31, and the second end of the fixed locking frame 41 is arranged to be cantilevered outward in the lateral direction. The fixed locking frame is provided with a locking through hole for cooperating with the sling between the frame bodies 31. The locking abutment head 42 is fixedly provided at the first end of the sling 32 and is located above the fixed locking frame. The transverse cross section of the locking abutment head is larger than the cross section of the locking through hole.

[0041] Furthermore, the locking support head 42 includes a locking block and a locking bolt. The two locking blocks are spliced ​​together to clamp the sling and are fixedly connected by the locking bolt.

[0042] Understandably, by arranging the locking safety mechanism 40, the locking through hole of the locking safety mechanism 40 can both limit the swing of the belt in the length direction to prevent the belt from falling off the tension roller 332, and at the same time, provide temporary support by the locking safety mechanism 40 when the first end of the belt falls off, further improving safety. In this utility model, the lower limit constraint by arranging the locking safety mechanism 40 does not affect the degree of freedom for fine adjustment when the belt rises.

[0043] Furthermore, the belt adjustment mechanism 34 includes a hydraulic lifting cylinder 341 and a pulling plate 342. The hydraulic lifting cylinder 341 is fixedly mounted on the top surface of the frame 31 along the height direction of the frame 31. The fixed end of the hydraulic lifting cylinder 341 is fixedly connected to the frame 31, and the lifting movable end of the hydraulic lifting cylinder 341 is fixedly connected to the first end of the pulling plate 342. The second end of the pulling plate 342 protrudes outward and is connected to the first end of the sling 32. Preferably, the hydraulic lifting cylinder 341 is arranged at the end of the frame 31 and close to the wide edge, aligned with the locking safety mechanism 40. The first end of the pulling rod is fixedly mounted on the top of the hydraulic lifting cylinder 341, and the second end of the pulling rod protrudes slightly outward and is provided with the belt.

[0044] Furthermore, the belt adjustment mechanism 34 includes a winch fixedly mounted on the top surface of the frame 31. The first end of the winch is fixedly connected to the frame 31, and the winding end of the winch is connected to the first end of the sling 32. Preferably, the winch is located at the middle of the frame 31 in the end direction, and the winding end of the winch is arranged towards the locking safety mechanism 40.

[0045] Furthermore, slings 20 are connected to the four corner positions of the suspender 30, and the suspender 30 is suspended from the hook 10 by the four slings 20. In this utility model, the arrangement of four slings 20 helps to maintain stability during hoisting.

[0046] Furthermore, the frame 31 includes a rectangular frame, reinforcing ribs, and connecting hooks. Multiple reinforcing ribs are arranged at intervals along the length of the rectangular frame. Connecting hooks are provided on both sides of the rectangular frame, and the connecting hooks are arranged near the corners of the rectangular frame.

[0047] Furthermore, multiple connecting hooks are arranged at intervals along the length of the rectangular frame. The multiple connecting hooks facilitate adjustment of the lifting distance of the hook 10.

[0048] This utility model also provides a wind power system, including a foundation tower, a nacelle, a hub, and blades. The nacelle is rotatably mounted on the top of the foundation tower around its circumference. The front end of the nacelle is cantilevered outward and has a hub arranged thereon. The hub is rotatably mounted around the central axis of the installation. The blades are connected to the hub via flanges and fixed with fastening bolts. The flange connection end of the hub has a positioning hole. The flange connection end of the blade is fixed with a threaded positioning rod, which passes through the positioning hole. Multiple blades are evenly spaced on the hub along its circumference. The blades are hoisted and assembled onto the hub using the aforementioned wind power installation frame 100.

[0049] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
