Description

Technical Field

[0001] The present invention relates to the technical field of equipment for manufacturing wind turbine towers, and in particular to a wind turbine tower cutting device and a cutting method. Background Art

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

[0003] In the process of manufacturing wind turbine towers, in order to facilitate the subsequent welding and installation of tower door frames, it is necessary to complete the preliminary work of beveling the reserved area of ​​the tower panel door frame. However, when beveling the reserved area of ​​the panel door frame, due to the non-fixed shape of the door frame opening (most wind turbine tower door frames are runway-shaped elliptical structures, including some circular door frame opening structures), traditional cutting equipment cannot achieve intelligent beveling. Therefore, it is necessary to manually hold or control the cutting equipment according to a fixed track set in advance to process the bevel of the plate. On the one hand, this cutting method will cause fatigue to operators who work for a long time and is cumbersome and inconvenient to use. On the other hand, it cannot adapt to the processing of bevels of wind turbine towers of different sizes and has limitations.

[0010] The cutting mechanism includes a base, a telescopic guide rail, a sliding platform, a cutting arm, and a driving unit. The base is installed on the surface of the double-head push rod. There are two bases. A telescopic guide rail is fixedly installed between the two bases. The sliding platform is slidably installed on the surface of the telescopic guide rail. The cutting arm is installed on the surface of the sliding platform. The driving unit is installed inside the telescopic guide rail and the sliding platform.

[0011] The driving unit includes a rubber wheel, a second motor, and a slide groove. A plurality of rubber wheels are rotatably installed inside the sliding platform. The rubber wheels are divided into two groups and are symmetrically distributed on both sides of the rubber wheel. A second motor is fixedly installed on the outer wall of the sliding platform. The output end of the second motor horizontally penetrates into the sliding platform. The output end of the second motor is connected to the rubber wheel. A slide groove is penetrated through the side wall of the telescopic guide rail. The outer side of the rubber wheel is squeezed and contacted with the inside of the slide groove.

[0014] By providing a base structure placed on the top of two double-headed push rods, coordinating the lateral movement of the two bases, the telescopic guide rail between the bases is stretched synchronously, causing the length of the telescopic guide rail to change accordingly, thereby coordinating the movement of the sliding platform to drive the cutting arm to cut the straight surface of the reserved area of ​​the elliptical door frame of the plate, thereby ensuring the automation of the cutting and beveling processing of the equipment, so that it can match plates of different sizes, with a wide range of applications, good cutting effect, high efficiency, saving manpower, saving time, and more convenient operation.

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

[0017] By providing a connecting shell structure rotatably mounted 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 in contact with the inner wall of the reserved area of ​​the plate door frame can form an extrusion clamp for the plate and rotate synchronously. However, after the plate is grooved, the sandpaper track and the connecting shell in contact with the plate again can rotate to match the angle of the groove. While rotating, the slot under the sandpaper track will be restricted by the engagement of the plug 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, thereby achieving the dual functions of clamping and cleaning the plate at the same time, further improving the functionality of the device.

[0018] A cutting method for a wind power tower cutting device, the method comprising the following steps: 1) Place the plate to be processed on the surface of the storage table, let the two bases be distributed inside the plate, measure the radius length 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, and stretch them horizontally and vertically according to the measured data to form a relative push on the base and the horizontal guide rail, so that the horizontal guide rail slides along the longitudinal guide rail and the base slides along the horizontal guide rail; 2) When the double-headed push rod extends outward, the first motor starts synchronously to drive the double-headed push rod to rotate and squeeze the inner wall of the plate. When the base slides along the transverse guide rail, it drives the two bases to move synchronously, and 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 segment; 3) Start the cutting arm, which rotates with the sliding platform as the center and cuts the plate. After the arc segment 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 segment. Repeat the above steps to complete the bevel cutting of the plate. 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 resets and retracts accordingly. When the output end of the double-headed push rod extends outward, the sandpaper track will fit the inner wall of the plate. As the first motor drives the double-headed push rod to rotate, the sandpaper track that fits the plate will rotate synchronously. When the groove cutting of the inner wall of the plate is completed, the connecting shell that contacts the inner wall of the plate again will rotate around the end of the rotating shaft and be squeezed and fit to 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 plug plate will engage, making the sandpaper track unable to rotate. The first motor drives 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.

On the one hand, this equipment can realize the full-automatic groove processing of the plate, improve the convenience of cutting, on the other hand, this equipment can match the cutting of plates of different shapes and sizes, and has a simple structure, low cost and higher functionality; at the same time, the clamping mechanism arranged at the end of the positioning mechanism can further grind and clean the slope after completing the cutting of the plate, thereby further improving the functionality and role of this equipment, and fully ensuring the quality of the groove of the wind power tower after cutting.

[0020] 2) By providing a base structure placed on the top of two double-headed push rods, the telescopic guide rail located between the bases is stretched synchronously with the lateral movement of the two bases, causing the length of the telescopic guide rail to change accordingly, thereby coordinating the movement of the sliding platform to drive the cutting arm to cut the straight surface of the reserved area of ​​the elliptical door frame of the plate, thereby ensuring the automation of the cutting groove processing of the equipment, so that it can match plates of different sizes, with a wide range of applications, good cutting effect, high efficiency, saving manpower, saving time, and more convenient operation.

[0021] 3) By providing a connecting shell structure that is rotatably mounted to the end of the double-headed push rod output shaft, 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 panel door frame can form an extrusion clamp for the panel and rotate synchronously. However, after the panel is grooved, the sandpaper track and the connecting shell that are in contact with the panel again can rotate to match the angle of the groove.

[0032] Instructions for use: The operator places the plate 2 to be processed on the top of the storage table 1, and allows the two bases 303 to be distributed inside the plate 2. At the same time, it is necessary to measure the radius length of the arc segment 201 and the total length of the straight segment 202 in advance. Thereafter, the double-headed push rod 306 and the electric push rod 304 are controlled to operate, and the horizontal and vertical stretches are performed according to the data obtained from the survey. During the stretching process, the inside of the plate 2 will be squeezed, thereby forming a relative push on the base 303 and the horizontal guide rail 302, causing the horizontal guide rail 302 to slide along the longitudinal guide rail 301, and the base 303 to slide along the horizontal guide rail 302. During the process of the double-headed push rod 306 extending outward, the first motor 305 will start synchronously and drive the double-headed push rod 306 rotates and squeezes on the inner wall of the plate 2, so as to better push it relative to each other, and the base 303 will synchronously drive the two bases 401 to move during the sliding process along the transverse guide rail 302, so that the telescopic guide rail 402 located in the middle of the two bases 401 will be synchronously extended, and at this time, the second motor 4052 runs and drives the rubber wheel 4051 to rotate synchronously, and the rotating rubber wheel 4051 will move along the inside of the slide groove 4053, thereby driving the sliding platform 403 to move synchronously, so that the sliding platform 403 moves to the center of the arc segment 201, and starts the cutting arm 404, and the cutting arm 404 rotates with the sliding platform 403 as the center and cuts the plate 2 (the rotation radius of the cutting arm 404 is arc The radius of the surface segment 201), after completing the cutting of the arc surface segment 201, the second motor 4052 is started 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, and reciprocates to complete the bevel cutting work 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 be reset and retracted accordingly to prevent obstruction of the operation of the cutting arm 404; and 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.

When the inner wall of the plate 2 completes the groove cutting, the connecting shell 502 that contacts the inner wall of the plate 2 again will rotate around the end of the rotating shaft 501 and be squeezed and fitted to the inner wall of the plate 2. As the connecting shell 502 rotates, the sandpaper track 503 inside the connecting shell 502 will tilt synchronously and engage with the slot 504 and the plug plate 505, making the sandpaper track 503 unable to rotate. As the first motor 305 drives the double-headed push rod 306 to rotate and the base 303 moves again, the sandpaper track 503 will grind and clean the inner wall of the plate 2.

[0033] A spring 506 is fixedly connected between the plug plate 505 and the rotating shaft 501. When the groove angle of the plate 2 is large, the connecting shell 502 that contacts the inner wall of the plate 2 again will rotate around the end of the rotating shaft 501 and be pressed against the inner wall of the plate 2, and the sandpaper track 503 located inside the connecting shell 502 will be synchronously tilted to a large extent and engage with the plug plate 505 through the slot 504.

[0041] A spring 506 is fixedly connected between the plug plate 505 and the rotating shaft 501 , and a torsion spring 507 is fixedly connected between the connecting shell 502 and the interlayer of the rotating shaft 501 .

[0042] Instructions for use: The operator places the plate 2 to be processed on the top of the storage table 1, and allows the two bases 303 to be distributed inside the plate 2. At the same time, it is necessary to measure the radius length of the arc segment 201 and the total length of the straight segment 202 in advance. Thereafter, the double-headed push rod 306 and the electric push rod 304 are controlled to operate, and the horizontal and vertical stretches are performed according to the data obtained from the survey. During the stretching process, the inside of the plate 2 will be squeezed, thereby forming a relative push on the base 303 and the horizontal guide rail 302, causing the horizontal guide rail 302 to slide along the longitudinal guide rail 301, and the base 303 to slide along the horizontal guide rail 302. During the process of the double-headed push rod 306 extending outward, the first motor 305 will start synchronously and drive the double-headed push rod 306 rotates and squeezes on the inner wall of the plate 2, so as to better push it relative to each other, and the base 303 will synchronously drive the two bases 401 to move during the sliding process along the transverse guide rail 302, so that the telescopic guide rail 402 located in the middle of the two bases 401 will be synchronously extended, and at this time, the second motor 4052 runs and drives the rubber wheel 4051 to rotate synchronously, and the rotating rubber wheel 4051 will move along the inside of the slide groove 4053, thereby driving the sliding platform 403 to move synchronously, so that the sliding platform 403 moves to the center of the arc segment 201, and starts the cutting arm 404, and the cutting arm 404 rotates with the sliding platform 403 as the center and cuts the plate 2 (the rotation radius of the cutting arm 404 is arc The radius of the surface segment 201), after completing the cutting of the arc surface segment 201, the second motor 4052 is started 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, and reciprocates to complete the bevel cutting work 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 be reset and retracted accordingly to prevent obstruction of the operation of the cutting arm 404; and 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. When 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. When the inner wall of the plate 2 completes the groove cutting, the connecting shell 502 that contacts the inner wall of the plate 2 again will rotate around the end of the rotating shaft 501 and be squeezed and fitted to the inner wall of the plate 2. As the connecting shell 502 rotates, the sandpaper track 503 inside the connecting shell 502 will tilt synchronously and engage with the slot 504 and the plug plate 505, making the sandpaper track 503 unable to rotate. As the first motor 305 drives the double-headed push rod 306 to rotate and the base 303 moves again, the sandpaper track 503 will grind and clean the inner wall of the plate 2.

[0043] A spring 506 is fixedly connected between the plug plate 505 and the rotating shaft 501. When the groove angle of the plate 2 is large, the connecting shell 502 that contacts the inner wall of the plate 2 again will rotate around the end of the rotating shaft 501 and be pressed against the inner wall of the plate 2, and the sandpaper track 503 located inside the connecting shell 502 will be synchronously tilted to a large extent and engage with the plug plate 505 through the slot 504. The squeezed plug plate 505 can also drive the spring 506 to bend, thereby causing a small synchronous tilt. A torsion spring 507 is fixedly connected between the interlayer of the connecting shell 502 and the rotating shaft 501, and the torsion spring 507 is used to drive the connecting shell 502 to reset and rotate.

[0044] By providing a rubber sleeve 4055 structure that is in squeeze contact with the rubber wheel 4051, the squeeze contact between the rubber sleeve 4055 and the rubber wheel 4051 can provide greater friction when the rubber wheel 4051 rotates to ensure stable movement of the sliding platform 403, thereby ensuring the integrity of the operation of the equipment.
