Description

Technical Field

[0001] This invention relates to the technical field of equipment for manufacturing wind turbine towers, specifically to a wind turbine tower cutting device and cutting method. Background Technology

[0002] Wind energy is one of the important sources of clean energy, and wind power generation has been widely used around the world. In a wind power generation system, the wind turbine tower is an indispensable component. It supports the main body of the wind turbine and the turbine blades, playing a key role. The wind turbine tower is the tower of the wind power generation system. It mainly plays a supporting role in the wind turbine generator set, while also absorbing the vibration of the unit.

[0003] In the manufacturing process of wind turbine towers, in order to facilitate the subsequent welding and installation of the tower frame, it is necessary to complete the pre-work of beveling the reserved area of ​​the tower plate frame. However, when beveling the reserved area of ​​the plate frame, due to the non-fixed shape of the frame opening (most wind turbine tower frame openings are elliptical structures resembling racetracks, and some are circular frame opening structures), traditional cutting equipment cannot perform intelligent beveling. Therefore, it is necessary to manually hold the cutting equipment or control it to bevele the plate according to a pre-set fixed track. This cutting method will cause fatigue to the operators working for a long time and is cumbersome and inconvenient to use. In addition, it cannot adapt to the processing of beveling of wind turbine towers of different sizes, which has limitations.

[0004] The announcement number is CN214924810U, and the name is: Wind Turbine Tower Section Cutting Equipment. It includes a base plate with four support frames on top, a tilt adjustment assembly on top of the base plate, a cutting assembly on top of the base plate, and a fixing assembly inside the base plate. The tilt adjustment assembly includes two hinge seats and two metal strips. Both hinge seats are slidably connected to the top of the base plate, and the two metal strips are respectively hinged to the interior of the two hinge seats. This utility model facilitates ensuring cutting results, reduces cutting deviation, and facilitates subsequent welding while reducing the workload of workers.

[0005] While the aforementioned device can save manpower, it lacks a processing device in the later stages of cutting, which affects the cutting quality of the workpiece. Summary of the Invention

[0006] The purpose of this invention is to provide a wind turbine tower cutting device and method that has a more reasonable structural design, compact structure, small size, low processing and manufacturing cost, is easy to operate, can process bevels of wind turbine towers of different sizes, has a wide range of applications, good cutting effect, high cutting efficiency, and can clean the bevels of the cut wind turbine towers to ensure the processing quality of the bevels.

[0007] The present invention discloses a wind turbine tower cutting device, including a platform, a plate on the surface of the platform, the plate including an arc segment and a straight segment, the arc segment and the straight segment closing each other to form a door frame, a positioning mechanism in the middle of the platform, a cutting mechanism fixedly installed on the surface of the positioning mechanism, a drive unit fixedly installed inside the cutting mechanism, and clamping mechanisms fixedly installed at both ends of the positioning mechanism.

[0008] The positioning mechanism includes a longitudinal guide rail, a transverse guide rail, a base, an electric push rod, a first motor, and a double-headed push rod. There are two storage platforms, with a longitudinal guide rail positioned between them. One end of the longitudinal guide rail is fixedly installed on the inner wall of one side of the storage platform. A transverse guide rail is slidably installed on the surface of the longitudinal guide rail, and a base is slidably installed on the surface of the transverse guide rail. There are two bases, arranged side-by-side on the surface of the transverse guide rail. An electric push rod is horizontally installed on the side of one base, and its output end is horizontally connected to the other base. A first motor is vertically fixed at the end of each base, and its output end extends vertically through the surface of the base. A double-headed push rod is connected to the output end of the first motor, and a cutting mechanism is installed on the surface of the double-headed push rod. A clamping mechanism is installed at the output end of the double-headed push rod.

[0009] The positioning mechanism matches the size of the sheet metal, moving the cutting mechanism to the appropriate position for cutting. Simultaneously, the continuously operating positioning mechanism drives the clamping mechanism to grind and clean the bevel of the cut sheet metal. By placing the positioning mechanism in the middle of the sheet metal, its extension allows for lateral and longitudinal movement, moving the cutting mechanism to the designated position within the pre-reserved area of ​​the sheet metal frame. The drive unit controls the movement and rotation of the cutting mechanism, enabling beveling of the pre-reserved area of ​​the traditional wind turbine tower sheet metal frame, replacing manual hand-held cutting. This equipment achieves fully automatic beveling, improving cutting convenience. Furthermore, it is simple in structure, low in cost, and highly functional, capable of cutting sheets of different shapes and sizes. The clamping mechanism at the end of the positioning mechanism further grinds and cleans the bevel after cutting, further enhancing the equipment's functionality and ensuring the quality of the beveled wind turbine tower.

[0010] The cutting mechanism includes a base, a telescopic guide rail, a sliding platform, a cutting arm, and a drive unit. The surface of the double-headed push rod is equipped with a base, and there are two bases. A telescopic guide rail is fixedly installed between the two bases. The surface of the telescopic guide rail is slidably mounted with a sliding platform, and the surface of the sliding platform is equipped with a cutting arm. The drive unit is installed inside the telescopic guide rail and the sliding platform.

[0011] The drive unit includes rubber wheels, a second motor, and a slide groove. Multiple rubber wheels are rotatably installed inside the sliding platform. The rubber wheels are divided into two groups and symmetrically distributed on both sides of the inside of the rubber wheels. The second motor is fixedly installed on the outer wall of the sliding platform. The output end of the second motor extends horizontally into the inside of the sliding platform and is connected to the rubber wheels. A slide groove is opened through the side wall of the telescopic guide rail. The outer side of the rubber wheel presses against the inside of the slide groove. The outer walls of the rubber wheels in the same group are connected to a belt for transmission.

[0012] A rubber sleeve is fixedly installed on the inner wall of the chute, and the rubber sleeve and the outer wall of the rubber wheel are in contact by compression.

[0013] Each base has a rotatable adapter mounted on its bottom surface, and the bottom surface of the adapter is rotatably mounted on the surface of the double-headed push rod.

[0014] The equipment features a base structure that rests on top of two double-headed push rods. The lateral movement of these two bases simultaneously stretches the telescopic guide rail located between the bases, causing a corresponding change in the length of the guide rail. This, in conjunction with the movement of the sliding platform, drives the cutting arm to cut the straight surface of the pre-reserved area of ​​the elliptical door frame, ensuring automated beveling. This allows the equipment to accommodate plates of different sizes, offering a wide range of applications, excellent cutting results, high efficiency, labor savings, time savings, and more convenient operation.

[0015] The clamping mechanism includes a rotating shaft, a connecting shell, a sandpaper track, a slot, and an insert plate. The output shaft of the double-headed push rod is fixedly connected to the rotating shaft, and the connecting shell is rotatably installed at the other end of the rotating shaft. The sandpaper track is rotatably installed inside the connecting shell. Multiple slots are evenly arranged on the side wall of the sandpaper track. An insert plate is provided on the bottom surface of the rotating shaft. The insert plate extends into the interior of the connecting shell and can be engaged with the interior of the slot.

[0016] A spring is fixedly connected between the insert plate and the rotating shaft, and a torsion spring is fixedly connected between the interlayer of the connecting shell and the rotating shaft.

[0017] By setting a connecting shell structure that is rotatably installed to the end of the output shaft of the double-headed push rod, when the output end of the double-headed push rod extends outward and rotates, the sandpaper track that contacts the inner wall of the reserved area of ​​the plate frame can form a squeezing and clamping of the plate and rotate synchronously. However, after the plate is beveled, the sandpaper track and the connecting shell that are in contact with the plate again can match the angle of the bevel and rotate. At the same time, the slot located below the sandpaper track will be restricted by the locking of the insert plate, so that the sandpaper track cannot rotate and cooperate with the relative movement of the double-headed push rod to grind and clean the plate. Thus, the dual function of clamping and cleaning the plate is achieved at the same time, further improving the functionality of the equipment.

[0018] By providing a sliding groove structure through the side of the telescopic guide rail, the rotation of the rubber wheel is driven by a second motor, causing the rubber wheel to move horizontally along the inside of the sliding groove, thereby synchronously driving the sliding platform and the cutting arm to move synchronously, thus ensuring the perfect operation of the equipment.

[0019] By incorporating a rubber sleeve structure that presses against the rubber wheel, the pressing contact between the rubber sleeve and the rubber wheel provides greater friction when the rubber wheel rotates, ensuring the stable movement of the sliding platform and thus guaranteeing the integrity of the equipment's operation.

[0020] A cutting method for a wind turbine tower cutting device, the method comprising the following steps:

[0021] 1) Place the workpiece to be processed on the surface of the platform, with the two bases distributed inside the workpiece. Measure the radius of the arc segment and the total length of the straight segment. Control the operation of the double-headed push rod and the electric push rod to extend laterally and longitudinally according to the measured data, forming a relative push on the base and the transverse guide rail, causing the transverse guide rail to slide along the longitudinal guide rail and the base to slide along the transverse guide rail.

[0022] 2) During the outward extension of the double-headed push rod, the first motor starts synchronously and drives the double-headed push rod to rotate and press against the inner wall of the plate. When the base slides along the transverse guide rail, it drives the two bases to move synchronously. The telescopic guide rail extends synchronously. At this time, the second motor runs and drives the rubber wheel to rotate synchronously. The rotating rubber wheel will move along the inside of the slide groove, driving the sliding platform to move synchronously, so that the sliding platform moves to the center of the arc section.

[0023] 3) Start the cutting arm. The cutting arm rotates around the sliding platform and cuts the plate. After the arc section is cut, the second motor starts again and drives the sliding platform and the cutting arm to move synchronously. The cutting arm cuts the straight section. Repeat the above steps to complete the beveling of the plate.

[0024] 4) When the cutting arm cuts along the inner wall of the plate and moves to the output end of the double-headed push rod, and contacts the inner wall of the plate, the double-headed push rod will retract and retract accordingly. When the output end of the double-headed push rod extends outward, the sandpaper track will adhere to the inner wall of the plate. As the first motor drives the double-headed push rod to rotate, the sandpaper track that is in contact with the plate will rotate synchronously. After the inner wall of the plate is beveled, the connecting shell that contacts the inner wall of the plate again will rotate around the end of the rotating shaft and press against the inner wall of the plate. As the connecting shell rotates, the sandpaper track inside the connecting shell will tilt synchronously, and the slot and the insert plate will engage, preventing the sandpaper track from rotating. The first motor will drive the double-headed push rod to rotate and the base to move again, and the sandpaper track will grind and clean the inner wall of the plate.

[0025] Beneficial effects of this invention:

[0026] 1) The positioning mechanism matches the size of the plate and moves the cutting mechanism to the appropriate position to cut the plate. Simultaneously, the continuously operating positioning mechanism drives the clamping mechanism to grind and clean the bevel of the cut plate. By placing the positioning mechanism in the middle of the plate, its extension allows for lateral and longitudinal movement, driving the cutting mechanism to move and position it at the designated location within the pre-reserved area of ​​the plate's door frame. The drive unit controls the movement and rotation of the cutting mechanism, enabling beveling of the pre-reserved area of ​​the door frame of traditional wind turbine tower plates, replacing manual hand-held cutting. This equipment achieves fully automatic beveling of plates, improving cutting convenience. Furthermore, it is simple in structure, low in cost, and highly functional while matching plates of different shapes and sizes. The clamping mechanism at the end of the positioning mechanism further grinds and cleans the bevel after cutting, further enhancing the equipment's functionality and ensuring the quality of the beveled wind turbine tower plate.

[0027] 2) By setting up a base structure that rests on top of two double-headed push rods, and coordinating the lateral movement of the two bases, the telescopic guide rail located between the bases is stretched synchronously, causing the length of the telescopic guide rail to change accordingly. This, in conjunction with the movement of the sliding platform, drives the cutting arm to cut the straight surface of the reserved area of ​​the elliptical door frame, ensuring the automation of the cutting bevel processing of this equipment. This allows it to match plates of different sizes, has a wide range of applications, good cutting effect, high efficiency, saves manpower and time, and makes operation more convenient.

[0028] 3) By using a connecting shell structure that is rotatably mounted to the output shaft end of the double-headed push rod, when the output end of the double-headed push rod extends outward and rotates, the sandpaper track in contact with the inner wall of the reserved area of ​​the plate frame can form a squeezing and clamping effect on the plate and rotate synchronously. However, after the plate is beveled, the sandpaper track and the connecting shell that are in contact with the plate again can match the angle of the bevel and rotate. At the same time, the slot located below the sandpaper track will be restricted by the engagement of the insert plate, causing the sandpaper track to be unable to rotate and cooperate with the relative movement of the double-headed push rod to grind and clean the plate, thereby simultaneously achieving the grinding and cleaning of the plate. The dual function of clamping and cleaning the plates further enhances the functionality of this equipment. A sliding groove structure is installed through the side of the telescopic guide rail, and a second motor drives the rotation of the rubber wheel, causing the rubber wheel to move horizontally along the inside of the groove. This synchronously drives the sliding platform and the cutting arm, ensuring the smooth operation of the equipment. A rubber sleeve structure is provided that presses against the rubber wheel. This pressing contact between the sleeve and the wheel provides greater friction when the wheel rotates, ensuring the stable movement of the sliding platform and guaranteeing the smooth operation of the equipment.

[0044] Each base 401 has a rotatable adapter 6 mounted on its bottom surface, and the bottom surface of the adapter 6 is rotatably mounted on the surface of the double-headed push rod 306.

[0045] The clamping mechanism 5 includes a rotating shaft 501, a connecting shell 502, a sandpaper track 503, a slot 504, and an insert plate 505.

An insert plate 505 is provided on the bottom surface of the rotating shaft 501. The insert plate 505 extends into the interior of the connecting shell 502 and can be engaged inside the slot 504.

[0046] A spring 506 is fixedly connected between the insert plate 505 and the rotating shaft 501, and a torsion spring 507 is fixedly connected between the interlayer of the connecting shell 502 and the rotating shaft 501.

[0047] Instructions for use: The operator places the workpiece 2 to be processed on top of the platform 1, with the two bases 303 positioned inside the workpiece 2. Simultaneously, the radius of the curved section 201 and the total length of the straight section 202 need to be measured beforehand. Then, the operator controls the double-headed push rod 306 and the electric push rod 304 to extend laterally and longitudinally according to the measured data. During this extension, the push rod will compress the interior of the workpiece 2, creating a relative push on the bases 303 and the transverse guide rail 302. This causes the transverse guide rail 302 to slide along the longitudinal guide rail 301, and the bases 303 to slide along the transverse guide rail 302. As the double-headed push rod 306 extends outward, the first motor 305 will start simultaneously and drive the double-headed push rod. 306 rotates and presses against the inner wall of plate 2, thereby better pushing relative to each other. As the base 303 slides along the transverse guide rail 302, it simultaneously drives the two bases 401 to move, causing the telescopic guide rail 402 located in the middle of the two bases 401 to extend synchronously. At this time, the second motor 4052 runs and drives the rubber wheel 4051 to rotate synchronously. The rotating rubber wheel 4051 moves along the inside of the slide groove 4053, thereby driving the sliding platform 403 to move synchronously. The sliding platform 403 moves to the center of the arc segment 201 and starts the cutting arm 404. The cutting arm 404 rotates around the sliding platform 403 and cuts the plate 2 (the rotation radius of the cutting arm 404 is the radius of the arc). After the radius of the arc segment 201 is cut, the second motor 4052 starts again and drives the sliding platform 403 and the cutting arm 404 to move synchronously. During the movement, the cutting arm 404 cuts the straight segment 202. This process is repeated to complete the beveling of the plate 2. When the cutting arm 404 cuts along the inner wall of the plate 2 and moves to the contact surface between the output end of the double-headed push rod 306 and the inner wall of the plate 2, the double-headed push rod 306 needs to perform a corresponding reset extension to prevent obstruction of the cutting arm 404. When the output end of the double-headed push rod 306 extends outward, the sandpaper track 503 located inside the connecting shell 502 at the end of the double-headed push rod 306 will contact the inner wall of the plate 2. As the first motor 305 drives the double-headed push rod 306 to rotate, the sandpaper track 503 that is in contact with the plate 2 will rotate synchronously. After the inner wall of the plate 2 has completed the beveling cut, the connecting shell 502 that is in contact with the inner wall of the plate 2 again will rotate around the end of the rotating shaft 501 and press against the inner wall of the plate 2. As the connecting shell 502 rotates, the sandpaper track 503 located inside the connecting shell 502 will tilt synchronously and engage with the slot 504 and the insert plate 505, so that the sandpaper track 503 cannot rotate. With the first motor 305 driving the double-headed push rod 306 to rotate again and the base 303 moving, the sandpaper track 503 will grind and clean the inner wall of the plate 2.

[0048] A spring 506 is fixedly connected between the insert plate 505 and the rotating shaft 501. When the bevel angle of the plate 2 is large, the connecting shell 502, which is in contact with the inner wall of the plate 2 again, will rotate around the end of the rotating shaft 501 and press against the inner wall of the plate 2. The sandpaper track 503 located inside the connecting shell 502 will tilt synchronously and engage with the insert plate 505 through the slot 504. The compressed insert plate 505 can also drive the spring 506 to bend, thus causing a small synchronous tilt. A torsion spring 507 is fixedly connected between the connecting shell 502 and the rotating shaft 501. The torsion spring 507 drives the connecting shell 502 to reset and rotate.

[0054] A rubber sleeve 4055 is fixedly installed on the inner wall of the slide groove 4053, and the rubber sleeve 4055 and the outer wall of the rubber wheel 4051 are in contact by compression.

[0055] Each base 401 has a rotatable adapter 6 mounted on its bottom surface, and the bottom surface of the adapter 6 is rotatably mounted on the surface of the double-headed push rod 306.

[0056] The clamping mechanism 5 includes a rotating shaft 501, a connecting shell 502, a sandpaper track 503, a slot 504, and an insert plate 505. The output shaft end of the double-headed push rod 306 is fixedly connected to the rotating shaft 501. The connecting shell 502 is rotatably installed at the other end of the rotating shaft 501. The sandpaper track 503 is rotatably installed inside the connecting shell 502. Multiple slots 504 are evenly arranged on the side wall of the sandpaper track 503. An insert plate 505 is provided on the bottom surface of the rotating shaft 501. The insert plate 505 extends into the interior of the connecting shell 502 and can be engaged inside the slot 504.

[0057] A spring 506 is fixedly connected between the insert plate 505 and the rotating shaft 501, and a torsion spring 507 is fixedly connected between the interlayer of the connecting shell 502 and the rotating shaft 501.

[0058] Instructions for use: The operator places the workpiece 2 to be processed on top of the platform 1, with the two bases 303 positioned inside the workpiece 2. Simultaneously, the radius of the curved section 201 and the total length of the straight section 202 need to be measured beforehand. Then, the operator controls the double-headed push rod 306 and the electric push rod 304 to extend laterally and longitudinally according to the measured data. During this extension, the push rod will compress the interior of the workpiece 2, creating a relative push on the bases 303 and the transverse guide rail 302. This causes the transverse guide rail 302 to slide along the longitudinal guide rail 301, and the bases 303 to slide along the transverse guide rail 302. As the double-headed push rod 306 extends outward, the first motor 305 will start simultaneously and drive the double-headed push rod. 306 rotates and presses against the inner wall of plate 2, thereby better pushing relative to each other. As the base 303 slides along the transverse guide rail 302, it simultaneously drives the two bases 401 to move, causing the telescopic guide rail 402 located in the middle of the two bases 401 to extend synchronously. At this time, the second motor 4052 runs and drives the rubber wheel 4051 to rotate synchronously. The rotating rubber wheel 4051 moves along the inside of the slide groove 4053, thereby driving the sliding platform 403 to move synchronously. The sliding platform 403 moves to the center of the arc segment 201 and starts the cutting arm 404. The cutting arm 404 rotates around the sliding platform 403 and cuts the plate 2 (the rotation radius of the cutting arm 404 is the radius of the arc). After the radius of the arc segment 201 is cut, the second motor 4052 starts again and drives the sliding platform 403 and the cutting arm 404 to move synchronously. During the movement, the cutting arm 404 cuts the straight segment 202. This process is repeated to complete the beveling of the plate 2. When the cutting arm 404 cuts along the inner wall of the plate 2 and moves to the contact surface between the output end of the double-headed push rod 306 and the inner wall of the plate 2, the double-headed push rod 306 needs to perform a corresponding reset extension to prevent obstruction of the cutting arm 404. When the output end of the double-headed push rod 306 extends outward, the sandpaper track 503 located inside the connecting shell 502 at the end of the double-headed push rod 306 will contact the inner wall of the plate 2. As the first motor 305 drives the double-headed push rod 306 to rotate, the sandpaper track 503 that is in contact with the plate 2 will rotate synchronously. After the inner wall of the plate 2 has completed the beveling cut, the connecting shell 502 that is in contact with the inner wall of the plate 2 again will rotate around the end of the rotating shaft 501 and press against the inner wall of the plate 2. As the connecting shell 502 rotates, the sandpaper track 503 located inside the connecting shell 502 will tilt synchronously and engage with the slot 504 and the insert plate 505, so that the sandpaper track 503 cannot rotate. With the first motor 305 driving the double-headed push rod 306 to rotate again and the base 303 moving, the sandpaper track 503 will grind and clean the inner wall of the plate 2.

[0059] A spring 506 is fixedly connected between the insert plate 505 and the rotating shaft 501. When the bevel angle of the plate 2 is large, the connecting shell 502, which is in contact with the inner wall of the plate 2 again, will rotate around the end of the rotating shaft 501 and press against the inner wall of the plate 2. The sandpaper track 503 located inside the connecting shell 502 will tilt synchronously and engage with the insert plate 505 through the slot 504. The compressed insert plate 505 can also drive the spring 506 to bend, thus causing a small synchronous tilt. A torsion spring 507 is fixedly connected between the connecting shell 502 and the rotating shaft 501. The torsion spring 507 drives the connecting shell 502 to reset and rotate.

[0060] By setting a rubber sleeve 4055 structure that presses against the rubber wheel 4051, the rubber sleeve 4055 and the rubber wheel 4051 can provide greater friction when the rubber wheel 4051 rotates, thus ensuring the stable movement of the sliding platform 403 and ensuring the integrity of the equipment operation.

Measure the radius length of the arc segment (201) and the total length of the straight segment (202). Control the double-headed push rod (306) and the electric push rod (304) to run, and extend laterally and longitudinally according to the measured data to form a relative push on the base (303) and the transverse guide rail (302), causing the transverse guide rail (302) to slide along the longitudinal guide rail (301) and the base (303) to slide along the transverse guide rail (302); 2) During the outward extension of the double-headed push rod (306), the first motor (305) starts synchronously and drives the double-headed push rod (306) to rotate and press against the inner wall of the plate (2). When the base (303) slides along the transverse guide rail (302), it drives the two bases (401) to move synchronously. The telescopic guide rail (402) extends synchronously. At this time, the second motor (4052) runs and drives the rubber wheel (4051) to rotate synchronously. The rotating rubber wheel (4051) will move along the inside of the slide groove (4053), driving the sliding platform (403) to move synchronously, so that the sliding platform (403) moves to the center of the arc section (201). 3) Start the cutting arm (404).
