[0002] During the welding process of wind turbine anchor plates, although the structure of the wind turbine anchor plate flange is similar to that of an ordinary flange, its size is very large due to its special application field. Therefore, during the processing and manufacturing process, it can only be made into two semi-circular ring structures first, and then spliced ​​and welded into a whole.

[0003] In the existing wind turbine anchor plate flange welding processing, the document with publication number CN218135990U discloses a wind turbine anchor plate flange welding auxiliary mechanism, which places the flange body on the processing plate, and then pulls the positioning plate to use the elastic force of the spring to position the flange body on the fixed plate. This fixing method is not firm, and cannot ensure that the welds of the two wind turbine anchor plate flanges are aligned during welding, and the stability of the welding operation cannot be guaranteed; for example, the document with publication number CN213053362U discloses a wind turbine anchor plate flange auxiliary welding device. Although this mechanism can ensure that the two wind turbine anchor plate flanges are flush and the wind turbine anchor plate flange welds are aligned, there is obstruction at the weld, which affects welding. Therefore, it is necessary to provide a wind turbine anchor plate welding processing auxiliary structure that can ensure that the welds are aligned and the welds will not be obstructed.

[0028] Among them, a downward pressing component 400 for pressing the wind turbine anchor plate flange is fixedly installed on the supporting platform 300, an adjustable auxiliary positioning component 500 is installed inside the supporting platform 300, and a docking component 600 is installed under the placement frame 200. The docking component 600 pulls the two slides 202 to move closer to each other.

[0029] In this embodiment, the downward pressure assembly 400 includes an L-shaped bracket 401 fixedly set on the supporting platform 300, with a nut 402 embedded between the L-shapes, a stud 403 inserted into the nut 402 for threaded engagement, and a pressure plate 404 fixedly set at the bottom end of the stud 403. The stud 403 is moved downward along the nut 402 by rotating it until the pressure plate 404 contacts and presses the wind turbine anchor plate flange.

[0030] In this embodiment, the adjustable auxiliary positioning assembly 500 includes two axle pins 501 that are rotatably arranged inside the support platform 300 and are symmetrically distributed. A turntable 502 and a worm gear 503 distributed from top to bottom are fixedly sleeved on the outer walls of the two axle pins 501. Two worm gears 504 that are perpendicular to the axle pins 501 are rotatably arranged inside the support platform 300. The two worm gears 504 are respectively engaged with the two worm gears 503. When the worm gear 504 rotates, it drives the axle pins 501 to rotate through the worm gear 503, so that the turntable 502 rotates by a certain angle.

[0031] In this embodiment, the ends of the two worm gears 504 pass through the outside of the supporting platform 300 and are fixedly sleeved with gears 505. The two gears 505 are meshed with each other. When one of the worm gears 504 rotates, it drives the gear 505 connected to it to rotate. The gear 505 rotates the other worm gear 504 by cooperating with the other gear 505. The rotation directions of the two worm gears 504 are opposite.

[0032] In this embodiment, a number of screw holes 506 distributed in a linear array are provided on the turntable 502, and an auxiliary pin 507 is connected to the inner thread of one of the screw holes 506. The auxiliary pin 507 can be inserted into the flange hole of the wind turbine anchor plate flange. The auxiliary pin 507 cooperates with the positioning pin 700 to perform multi-point positioning of the flange.

[0033] In this embodiment, the top end of the stud 403 and the end of one of the worms 504 are fixedly connected to a handwheel 508 , and the setting of the handwheel 508 facilitates the rotation of the stud 403 and the worm 504 .

[0034] In this embodiment, the docking assembly 600 includes a connecting frame 601 fixedly connected to the bottom of the placement frame 200, a motor 602 is fixedly installed on the top of the connecting frame 601, a rotating plate 603 is fixedly connected to the output shaft of the motor 602, and connecting rods 604 are respectively hingedly installed between the two ends of the top of the rotating plate 603 and the two slides 202. The motor 602 drives the rotating plate 603 to rotate. When the rotating plate 603 rotates, it drives the connecting rod 604 and causes the connecting rod 604 to pull the slide 202, thereby realizing the movement of the slide 202 in the slide groove 201.

[0035] In this embodiment, the cross section of the slide 202 is an I-shaped slide. The slide 202 is engaged in the slide groove 201 and moves along the length direction of the slide groove 201. The slide 202 can move stably in the slide groove 201 so that the two flanges can be accurately docked.

[0036] How to use and working principle of this device:

[0037] When the device is in use, first place the two wind turbine anchor plate flanges that need to be welded on the bearing platform 300, match the flange holes on the wind turbine anchor plate flanges with the positioning pins 700, and then adjust one of the worm gears 504 to rotate. The worm gear 504 causes the other worm gear 504 to rotate along and in the opposite direction through two mutually meshing gears 505. When the worm gear 504 rotates, the shaft pin 501 is driven to rotate through the worm gear 503, so that the turntable 502 rotates along a certain angle. The two turntables 502 are opened synchronously, and a screw hole 506 on the turntable 502 is aligned with the flange hole on the wind turbine anchor plate flange. The auxiliary pin 507 is passed through the flange hole on the wind turbine anchor plate flange and screwed with the screw hole 506. The wind turbine anchor plate flange is positioned at multiple points by the positioning pins 700 and the auxiliary pins 507. After positioning, the stud 403 is rotated to move downward along the nut 402 until the pressure plate 404 contacts and presses the wind turbine anchor plate flange tightly.

[0038] After the wind turbine anchor plate flange is fixed, the motor 602 is turned on. The motor 602 drives the rotating plate 603 to rotate. When the rotating plate 603 rotates, it drives the two connecting rods 604 to pull the two slides 202 to move in the slide groove 201 respectively. The wind turbine anchor plate flanges on the supporting platform 300 on the two slides 202 are connected to the movement, which can ensure that the welds are aligned and will not be blocked.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
