Description

Technical Field

[0001] This invention relates to the field of integrated transfer and tilting devices, and in particular to a crane-controlled integrated transfer and tilting device and method for wind turbine towers. Background Technology

[0002] Wind turbine towers are typically cylindrical structures, usually made of rolled and welded steel plates. They have a certain height, which varies from tens to hundreds of meters depending on the wind farm environment and the wind turbine model.

[0003] The diameter of the tower also changes with the increase in height. Generally, the bottom diameter is larger to provide more stable support, while the top diameter is relatively smaller to accommodate the installation of the wind turbine nacelle.

[0004] Before installation and use, the raw materials need to be bent and welded inside the factory to produce suitable wind turbine towers. However, the transfer and turning devices inside the factory have the following defects: during use, the length of the wind turbine towers varies, so a fixed-interval traveling device needs to be installed under the tower to support it during transfer. However, a single support device cannot rotate the wind turbine tower during subsequent welding, thus requiring a second transfer after the initial transfer, which greatly increases time and cost.

[0005] Secondly, the current tilting devices on the market can only restrict the bottom and cannot provide effective support for the sides of the wind turbine tower. As a result, the wind turbine tower will sway or rotate very slowly during the rotation process.

[0006] Therefore, to address the above situation, we propose a crane-controlled integrated device and method for transferring and reversing wind turbine towers. Summary of the Invention

[0007] The purpose of this invention is to provide a crane-controlled integrated device and method for transferring and rotating wind turbine towers, in order to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a crane-controlled wind turbine tower transfer and overturning integrated device and method, comprising a connecting frame, an mounting frame provided below the connecting frame, and through slots provided on both outer and inner sides of the mounting frame;

[0009] The mounting frame has movable support plates slidably installed at both ends of its inner side. The upper sides of the movable support plates are rotatably installed with wheels, and the outer circumferential surface of the wheels is fitted with a tower.

[0010] A passive bevel gear is fixedly installed between the rotating wheels;

[0011] Movable connecting blocks are fixedly installed at both ends of the inner side of the movable support plate, and the movable connecting blocks are slidably installed inside the through groove.

[0012] A cavity rod is rotatably mounted on the outer upper surface of the movable connecting block. A reciprocating screw is provided on the inner side of the cavity rod. A symmetrical limiting rod is provided on the circumferential surface of the reciprocating screw. The inner side of the limiting rod is in contact with the outer side of the tower.

[0013] Preferably, a main bevel gear is rotatably mounted on the inner side of the movable support plate, and a secondary bevel gear is rotatably mounted on the inner side of the movable support plate, wherein the secondary bevel gear and the main bevel gear mesh.

[0014] Preferably, a connecting shaft is fixedly installed through the right side to the left side of the secondary bevel gear, and L-shaped drive rods are provided at both ends of the connecting shaft. Connecting rods are rotatably installed at both ends of the inner side of the movable support plate. The two ends of the connecting rods are slidably connected to the L-shaped drive rods. A drive bevel gear is fixedly installed at the upper end of the connecting rod, and the drive bevel gear meshes with the driven bevel gear.

[0015] By adopting the above technical solution, the secondary bevel gear can drive the connecting shaft to rotate during rotation, and the connecting shaft can cause the L-shaped drive rods at both ends to rotate during rotation, thereby causing the subsequent rotating wheel to rotate.

[0016] Preferably, a symmetrical connecting plate is fixedly installed at the inner center of the mounting bracket, and a drive motor is fixedly installed at the inner center of the connecting plate. A sliding hole is opened through the outer side to the inner side of the movable support plate. The output shaft of the drive motor passes through the sliding hole and is located on the outer side of the movable support plate. The output shaft of the drive motor is slidably connected to the main bevel gear.

[0017] By adopting the above technical solution, the drive motor can make the main bevel gear rotate during use. After the main bevel gear moves with the moving support plate, the main bevel gear can rotate after the protrusions on the slider and the output shaft circumference match, and the movement of the main bevel gear will not be affected.

[0018] Preferably, slots are fixedly installed at both ends of the outer side of the mounting bracket, and a sliding rod is fixedly installed between the slots. The outer side of the movable connecting block is slidably installed on the circumferential surface of the sliding rod, and a rotating connector is fixedly installed on the upper outer side of the movable connecting block. The rotating connector is rotatably connected to the cavity rod.

[0019] Preferably, a first motor is fixedly installed at the upper end of the cavity rod, the output shaft of the first motor is fixedly connected to the upper end of the reciprocating screw on the inner side, and a slider is rotatably installed on the circumferential surface of the reciprocating screw, and the inner side of the slider is rotatably connected to one end of the limiting rod.

[0020] Preferably, the outer and inner sides of the connecting frame are provided with traveling teeth, a drive winch is provided below the connecting frame, a driver is fixedly installed at the upper corner of the drive winch, and a traveling gear is fixedly installed on the output shaft of the driver, and the traveling gear and the traveling teeth mesh.

[0021] Preferably, a steel cable is provided at the lower inner end of the drive winch, and a lifting block is fixedly installed at the lower end of the steel cable. The lifting block is slidably installed inside the slot. Traveling frames are fixedly installed at both ends of the connecting frame, and track teeth are provided at the lower end of the traveling frame. The two traveling frames are fixedly connected to each other.

[0022] Preferably, a second motor is fixedly installed on the outer side of the connecting plate, a first rotating rod is fixedly installed on the output shaft of the second motor, a second rotating rod is rotatably installed on the other end of the first rotating rod, and the other end of the second rotating rod is rotatably connected to the inner side of the movable support plate.

[0023] A crane-controlled integrated method for the transfer and tilting of wind turbine towers includes:

[0024] Preferably, in step one: the tower is placed above the mounting frame and fits against the outer side of the impeller;

[0025] Step 2: Start the drive motor. The output shaft of the drive motor drives the main bevel gear to rotate, the main bevel gear drives the secondary bevel gear to rotate, the secondary bevel gear drives the connecting shaft to rotate, and the connecting shaft drives the L-shaped drive rod to rotate.

[0026] Step 3: The L-shaped drive rod rotates the connecting rod, which in turn rotates the drive bevel gear. The drive bevel gear then rotates the driven bevel gear, which in turn rotates the rotating wheel, which in turn rotates the tower.

[0027] Step 4: The lifting block and the slot slide together, driving the drive winch. The drive winch moves the steel cable upward, the traveling frame moves along the track teeth, the traveling frame moves the connecting rod, the connecting rod moves the drive winch, the drive winch moves the steel cable, and the steel cable moves the mounting frame synchronously.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] 1. In the present invention, during use, the second motor is started, and the output shaft of the second motor causes the first and second rotating rods to rotate, thereby changing the distance between the front and rear moving support plates. After the distance is changed, the rotating wheel above it also changes, thus enabling rotation for wind turbine towers of different lengths. Moreover, after movement, the drive motor is started, and the drive motor, with the cooperation of the main bevel gear, the secondary bevel gear and other structures, enables the rotating wheel to rotate. During the rotation of the rotating wheel, the tower can rotate synchronously, thus eliminating the need for secondary transfer during subsequent welding or inspection.

[0030] 2. In this invention, the moving support plate can move synchronously with the cavity rod during its movement. When the cavity rod moves, the limiting rod can restrict the two sides of the tower, thereby forming a restriction and support on both sides of the tower, preventing the tower from swaying during rotation and increasing the rotation frequency.

[0031] 3. With the cooperation of the traveling frame and the lifting block, the mounting frame can be directly engaged with the slot on the outer side of the mounting frame. This allows the mounting frame to be moved directly during transportation, thus enabling the entire tower and structure to be transported together, avoiding the need for subsequent secondary transportation.

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] Please see Figures 1 to 12 The present invention provides a technical solution:

[0052] A crane-controlled integrated device for transferring and tilting wind turbine towers includes two track teeth 1. A traveling frame 2 is positioned above the track teeth 1, and a gear is mounted at the lower end of the traveling frame 2. The gear engages with the track teeth 1 and is driven by a motor or other drive device to allow the traveling frame 2 to move horizontally. The inner sides of the two traveling frames 2 are fixedly connected using a steel plate or frame structure. Figure 2 As shown.

[0053] A connecting frame 3 is fixedly installed between the upper inner sides of the two left and right traveling frames 2. The outer and inner sides of the connecting frame 3 are recessed, and a traveling tooth 301 is formed on its inner bottom surface. A drive winch 302 is located below the connecting frame 3, and a driver 303 is fixedly installed at each of the four corners of the drive winch 302. A traveling gear 304 is fixedly installed on the output shaft of the driver 303, and the traveling gear 304 meshes with the traveling tooth 301. During use, when the driver 303 is started, its output shaft rotates the traveling gear 304, thereby increasing or decreasing the distance between the left and right drive winches 302. Figure 3 As shown.

[0054] A steel cable 305 is provided inside the drive winch 302, and a lifting block 306 is fixedly installed at the lower end of the steel cable 305. The drive winch 302 can be started to retract or lower the steel cable 305, thereby allowing the lifting block 306 to move up and down. A mounting frame 4 is provided below the connecting frame 3. The mounting frame 4 has a rectangular structure, and slots 401 are fixedly installed on the outer side of each of the four corners. The lifting block 306 and the slots 401 are slidably engaged together. Therefore, when the lifting block 306 moves up and down, it can move the mounting frame 4 synchronously.

[0055] Then, symmetrical through slots 402 are provided on both outer and inner sides of the mounting bracket 4. Movable connecting blocks 404 are slidably installed inside the through slots 402. It should be noted that circular sliding rods 403 are fixedly installed between the slots 401 on the left and right sides. Rotary connecting heads 405 are fixedly installed on the upper outer surface of the movable connecting blocks 404. A cavity rod 406 is rotatably installed on the inner side of the upper end of the rotary connecting head 405. It should be noted that the position where the rotary connecting head 405 and the cavity rod 406 are rotatably connected is equipped with a damping device. Therefore, during use, manual or other device assistance is required to make the cavity rod 406 rotate, thus ensuring that the cavity rod 406 will not rotate on its own.

[0056] Secondly, a first motor 407 is fixedly installed on the top of the hollow rod 406. A reciprocating screw 408 is fixedly installed on the output shaft of the first motor 407. The reciprocating screw 408 is rotatably installed inside the hollow rod 406. Two symmetrical sliders 409 are threadedly mounted on the circumferential surface of the reciprocating screw 408. A limiting rod 410 is rotatably mounted on the outer side of the sliders 409 using a damping structure. Therefore, by adjusting the rotation angle of the limiting rod 410 during use, the two sides of the tower 6 above the mounting frame 4 can be restricted and supported. Figure 1 As shown, during use, when the first motor 407 is started, the output shaft of the first motor 407 will rotate the reciprocating screw 408, thereby adjusting the distance between the two sliders 409, and thus adjusting the distance between the upper and lower limiting rods 410.

[0057] Secondly, two symmetrical connecting plates 5 are fixedly installed at the inner center of the mounting bracket 4. A dual-shaft drive motor 501 is fixedly installed at the inner center of the connecting plate 5. Symmetrical pins protrude outwards from the circumferential surface of the output shaft of the drive motor 501. Figure 11 As shown.

[0058] Then, symmetrical movable support plates 505 are slidably installed at both ends of the inner side of the mounting bracket 4. Movable connecting blocks 404 are fixedly installed at both ends of the inner side of two adjacent movable support plates 505. The movable connecting blocks 404 keep the two adjacent movable support plates 505 in a fixed connection state. When the movable support plates 505 move, they can slide the movable connecting blocks 404 on the circumferential surface of the slide rod 403, thereby moving the rotating connector 405 and the cavity rod 406 synchronously, thereby adjusting the distance between the front and rear cavity rods 406.

[0059] Secondly, a main bevel gear 507 is rotatably mounted on the inner side of two adjacent movable support plates 505, and a secondary bevel gear 508 is rotatably mounted on the inner side. The main bevel gear 507 and the secondary bevel gear 508 mesh. Furthermore, a circular sliding hole 506 is formed at the midpoint between the outer and inner sides of the movable support plate 505. The output shaft of the drive motor 501 passes through the sliding hole 506 and is located on the outer side of the movable support plate 505. Additionally, a connecting hole matching the drive motor 501 is formed between the inner and outer sides of the main bevel gear 507. Moreover, a U-shaped groove with a recessed structure is formed on the inner wall of the connecting hole. Figure 10As shown, during use, the output shaft of the drive motor 501 passes through the main bevel gear 507 and the movable support plate 505. Furthermore, during rotation, the output shaft of the drive motor 501 can rotate the main bevel gear 507. When the main bevel gear 507 moves, it moves along with the movable support plate 505, and the output shaft of the drive motor 501 does not obstruct it. Figure 10 As shown

[0060] Then, a connecting shaft 509 is fixedly installed through the left and right sides of the secondary bevel gear 508. Four L-shaped drive rods 510 are arranged in a ring array at both ends of the connecting shaft 509. A connecting rod 511 is slidably installed on the upper end of the L-shaped drive rod 510. The connecting rod 511 is rotatably installed on the inner ends of the movable support plate 505. A drive bevel gear 512 is fixedly installed on the top of the connecting rod 511. Then, a rotating wheel 514 is rotatably installed on the upper end of the movable support plate 505. The front and rear rotating wheels 514 are fixedly connected by a cylinder. A driven bevel gear 513 is fixedly installed on the circumference of the cylinder. The driven bevel gear 513 meshes with the drive bevel gear 512.

[0061] During use, the drive motor 501 drives the main bevel gear 507 to rotate synchronously. The main bevel gear 507 drives the secondary bevel gear 508 to rotate synchronously. The secondary bevel gear 508 drives the connecting shaft 509 to rotate. The connecting shaft 509 drives the L-shaped drive rod 510 to rotate synchronously and slide. When the L-shaped drive rod 510 rotates, it drives the connecting rod 511 to rotate synchronously. When the connecting rod 511 rotates, it drives the drive bevel gear 512 to rotate. The drive bevel gear 512 drives the driven bevel gear 513 to rotate. The driven bevel gear 513 drives the cylinder to rotate. The cylinder drives the rotating wheel 514 to rotate. The rotating wheel 514 drives the tower 6 to rotate synchronously.

[0062] Secondly, four second motors 503 are fixedly installed on the outer sides of both connecting plates 5, which are rectangular in structure. A first rotating rod 502 is fixedly installed on the output shaft of each second motor 503. A second rotating rod 504 is rotatably installed on the outer end of each first rotating rod 502, and the outer end of each second rotating rod 504 is rotatably connected to the inner side of the movable support plate 505. Figure 9 As shown.

[0063] When in use, the second motor 503 is started. The output shaft of the second motor 503 drives the first rotating rod 502 to rotate. When the first rotating rod 502 rotates, it drives the second rotating rod 504 to rotate synchronously. When the second rotating rod 504 rotates, it can move the movable support plate 505, thereby adjusting the distance between the two movable support plates 505, so as to be suitable for towers 6 of different lengths.

[0064] Working principle: First, the tower 6 is placed on top of the mounting bracket 4 and then attached to the rotating wheel 514.

[0065] Rotate the cavity rod 406 to adjust the angle of the limiting rod 410, and then let the limiting rod 410 restrict the outer side of the tower 6.

[0066] Secondly, the drive motor 501 is started. The output shaft of the drive motor 501 drives the main bevel gear 507 to rotate synchronously. The main bevel gear 507 drives the secondary bevel gear 508 to rotate synchronously. The secondary bevel gear 508 drives the connecting shaft 509 to rotate. The connecting shaft 509 drives the L-shaped drive rod 510 to rotate synchronously and slide. When the L-shaped drive rod 510 rotates, it can drive the connecting rod 511 to rotate synchronously.

[0067] When the connecting rod 511 rotates, it drives the driving bevel gear 512 to rotate. The driving bevel gear 512 drives the passive bevel gear 513 to rotate. The passive bevel gear 513 drives the cylinder to rotate. The cylinder drives the rotating wheel 514 to rotate. The rotating wheel 514 drives the tower 6 to rotate synchronously.

[0068] Then, the lifting block 306 and the slot 401 are combined, and the drive winch 302 is started. The drive winch 302 carries the steel cable 305 to retrieve the tower, so that the mounting frame 4 can carry the tower 6 for transfer operations.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
