Description

Technical Field

[0001] The invention relates to the technical field of wind turbine flange shaping, and in particular to a wind turbine flange shaping device which is easy to fix. Background Art

[0002] Wind turbine flanges can be divided into tower flanges, tower base flanges, generator flanges and pitch frame flanges. The tower flange mainly connects the tower and the blade shaft, and bears the huge bending moment generated by the rotation of the blades; the tower base flange connects the tower base and the tower, and bears the wind turbine itself and the wind force; the generator flange connects the generator and the blade shaft, and bears the weight and rotational torque of the generator; the pitch frame flange connects the pitch frame and the blade shaft, and mainly controls the angle and speed of the blades.

[0003] When processing wind turbine flanges, after the workpiece is processed into a ring structure by a ring rolling machine, it needs to be shaped and finished. When finishing, the surface of the wind turbine flange needs to be polished first, and then the drilling process is performed.

[0004] The existing wind turbine flange shaping device includes a shaping mechanism and a rotating mechanism. The rotating mechanism is provided with a fixing mechanism. When the wind turbine flange is shaped, the wind turbine flange is fixed on the fixing mechanism. The rotating mechanism can drive the fixing mechanism and the flange to rotate, so as to facilitate the shaping mechanism to grind the rotating wind turbine flange. When grinding, grinding a certain thickness requires the wind turbine flange to rotate at least one circle, and the grinding efficiency is low. The position of the wind turbine flange is adjusted by the rotating mechanism, and the drill bit of the shaping mechanism drills holes in the designated positions of the wind turbine flange one by one. The drilling efficiency is low, resulting in low shaping efficiency of the wind turbine flange shaping device. Therefore, it is necessary to design a wind turbine flange shaping device with multiple drilling drill bits and grinding drill bits to improve the shaping efficiency of the wind turbine flange. In view of this, we propose a wind turbine flange shaping device that is easy to fix. Summary of the invention

The worm gear drive mode has a deceleration effect, which is convenient for the precise adjustment of the position of the quick connector 10, and after adjustment, the self-locking effect of the worm gear can be automatically fixed.

[0053] The present invention designs a planetary rotating mechanism 5 with at least two output ends, and the output end has a self-rotation state and a revolution state. The top end of the rotating column 8 is connected to the bottom end of the output end through a universal connecting mechanism 9, which indirectly enables at least two quick connectors 10 to also have a self-rotation state and a revolution state. When at least the quick connector 10 rotates, drill bits are installed on at least two quick connectors 10 to drill multiple holes of the wind power flange at the same time, thereby improving the grinding efficiency. When at least two quick connectors 10 revolve, grinding blocks are installed on the quick connectors 10, and multiple grinding blocks synchronously grind the surface of the wind power flange to improve the grinding efficiency. In addition, a diameter-changing mechanism 7 is designed to be suitable for wind power flanges of different sizes, thereby solving the technical problem of low shaping efficiency of the current wind power flange shaping device.

[0054] Working principle: When it is necessary to grind the inner and outer surfaces of the wind turbine flange, the adjusting handle 625 is rotated to rotate the adjusting tooth ring 624 and drive the three adjusting gears 623 to rotate, so that all the adjusting blocks 622 rotate synchronously. The two adjusting blocks 622 are arranged in a symmetrical structure, so that the narrow head end of the upper adjusting block 622 is engaged with the corresponding limiting arc groove 616, and the corresponding clamping rod 612 rotates relatively, and the upper clamping tooth block 614 is disengaged from the clamping tooth ring B584, and the wide head end of the lower adjusting block 622 has a gap corresponding to the limiting arc groove 616, and the lower adjusting block 622 is disengaged from the protrusion 615. The corresponding clamping rod 612 rotates relatively under the elastic force of the spring 613, so that the lower clamping tooth block 614 is engaged with the clamping tooth ring A572, so that the clamping tooth ring A572 cannot rotate;

[0055] The grinding blocks installed on the three quick connectors 10 refer to the grinding block positions and control the movable end of the lifting mechanism 3 to the appropriate lifting position through the external control mechanism;

[0056] The rotation of the output shaft of the second motor 714 through the external control mechanism hole can drive the worm 79 to rotate, causing the worm wheel 78 to rotate, so that the adjustment column 77 drives the mounting plate B711 and the three extended arc plates 712 to rotate relative to the mounting plate A71, and the movable arc groove 713 drives the movable ring block 70 to move along the movable straight groove 73, driving the three rotating columns 8 and the three quick connectors 10 to complete the synchronous diameter change control. When grinding the inner surface of the wind turbine flange, the grinding block is controlled to be close to the inner surface of the wind turbine flange, and when grinding the outer surface of the wind turbine flange, the grinding block is controlled to be close to the outer surface of the wind turbine flange;

[0057] The first motor 52 is controlled to rotate by an external control mechanism to drive the connecting shaft 592 and the sun gear 591 to rotate. When the fixing mechanism A6 is adjusted to fix the engaging gear ring A572, the sun gear 591 rotates to drive the three planetary gears 582 to perform planetary revolution around the sun gear 591, so that the mounting plate A71 and the mounting circular plate 581 rotate synchronously, the quick connector 10 revolves, and the grinding blocks installed on the three quick connectors 10 grind the inner and outer surfaces of the wind turbine flange at the same time; at this time, the planetary gear 582 still drives the rotating column 8 and the quick connector 10 to rotate, further improving the grinding effect;

[0058] When end surface grinding is required, the upper and lower end surfaces are ground, and the movable end of the lifting mechanism 3 is controlled to rise and fall through the external control mechanism, so that the grinding block contacts the wind turbine flange end. When the external control mechanism controls the first motor 52 to rotate so that the grinding block simultaneously grinds the wind turbine flange end surface, the output shaft of the second motor 714 through the external control mechanism hole continuously rotates, so that during the grinding process, the quick connector 10 is in a variable diameter state, which is convenient for the grinding block to fully grind the wind turbine flange end.

[0059] When it is necessary to drill a hole in the wind turbine flange, a drill bit is installed on the quick connector 10, and the adjustment handle 625 is adjusted so that the lower engaging tooth block 614 is disengaged from the engaging tooth ring A572, and the upper engaging tooth block 614 is engaged with the engaging tooth ring B584. At this time, the mounting circular plate 581 cannot rotate, and the rotation of the sun gear 591 drives the three planetary gears 582 to perform planetary rotation around the sun gear 591, so that the planetary gears 582 can drive the rotating column 8 to rotate relative to the movable ring block 70 through the universal connection mechanism 9, and the drill bit installed on the quick connector 10 synchronously drills holes in the three parts of the top of the wind turbine generator.
