Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine demoulding, in particular to a wind turbine base rapid demoulding device. Background Art

[0002] A wind turbine is an electric device that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. Wind turbines are divided into four types according to the capacity of the wind turbine: large, medium, small and micro. In the production process of small wind turbines, the wind turbine base components need to be cast and formed through a casting mold, and then the demolding device demolds the formed wind turbine base to separate the cast and formed wind turbine base from the mold. When the demolding device of some wind turbine bases is used, first, the casting raw material is injected into the mold cavity formed between the arc templates in the mold, and then static molding is performed, thereby realizing the preliminary casting and molding of the wind turbine base. Then, the power element drives the formed wind turbine base to slide vertically along the arc template under the action of the screw drive, thereby realizing the demolding operation of the wind turbine base. However, during the demolding process of the cast and formed wind turbine base, because its own outer arc surface is in close contact with the arc template, in order to avoid demolding wear interference between the two due to mutual contact and movement, it is necessary to reduce the demolding speed of the wind turbine base. This method reduces the preparation efficiency of the wind turbine base, and there is room for improvement. Utility Model Content

The lower end of the driving shaft and the outer bottom of the threaded barrel 51 are both provided with a gear 553, and the gears 553 are meshed and connected. A motor 552 is provided on the upper side of the fixed seat 551, and the input end of the motor 552 is connected to the output end of the single-chip microcomputer 2.

The transmission assembly 56 includes a rotating shaft 561, a rotating ring 562, an outer gear ring 563, a gear 564, a threaded barrel 565, a stud 566 and a bevel gear 567. The rotating shaft 561 is rotatably connected to the bottom wall of the casting outer mold shell 1 through a bearing. The inner wall of the casting outer mold shell 1 is rotatably connected with uniformly distributed threaded barrels 565 through a bearing. The interior of the threaded barrel 565 is threadedly connected with studs 566. The other end of the stud 566 is fixedly connected to the adjacent casting template 4. The middle part of the outer side of the threaded barrel 565 and the upper end of the rotating shaft 561 are provided with bevel gears 567. The two adjacent bevel gears 567 are meshed and connected. The bottom wall of the casting outer mold shell 1 is rotatably connected to the bottom wall of the casting outer mold shell 1 through a bearing. The bearing is rotatably connected with a rotating ring 562, and an outer gear ring 563 is arranged on the outer side of the rotating ring 562. A gear 2 564 is arranged at the lower end of the rotating shaft 561, and the gear 2 564 is meshed with the outer gear ring 563. A pulley 57 is arranged at the middle and lower end of the rotating shaft 561 on the far right. When demoulding the cast small wind turbine wind power base, the single chip computer 2 starts the motor 552 so that its output shaft drives the driving shaft to rotate forward. The driving shaft is meshed with the gears 553 to reverse the threaded barrel 1 51. The threaded barrel 1 51 is threadedly connected so that the stud 1 52 drives the top seat 53 to move up. The telescopic end of the limiting telescopic rod 54 extends out with the top seat 53, thereby avoiding the self-rotation phenomenon in the vertical movement of the top seat 53. During the upward movement of the top seat 53,The threaded barrel 1 51 is driven by a belt between a pulley 57 and a belt 58 so that the rightmost shaft 561 rotates. The two pulleys 57 have different diameters to avoid interference with the belt drive. The rightmost shaft 561 is meshed with the outer gear ring 563 through the gear 2 564 at the lower end so that the remaining shafts 561 rotate synchronously. The shaft 561 is meshed with the bevel gears 567 so that the threaded barrel 2 565 rotates synchronously. The threaded barrel 2 565 is threadedly connected so that the stud 2 566 drives the casting template 4 to move toward the end away from the center of the casting outer mold shell 1, so that the casting template 4 is automatically separated from the outer side of the cast wind turbine base. In this process, the telescopic end of the telescopic rod 3 moves adaptively with the casting template 4. When the top seat 53 moves up to a certain extent, the top seat 53 contacts the contact seat 7. As the top seat 53 continues to move up, the demoulding seat 10 drives the wind turbine base cast in the mold to move up quickly vertically through the contact seat 7, so as to demould the cast wind turbine base. The demoulding seat 10 is prevented from rotating during the vertical movement of the demoulding seat 10 by guiding the telescopic rod 11. During this process, the casting template 4 is away from the cast wind turbine base, and there is no contact obstruction between the two. The wind turbine base rapid demoulding device uses a transmission element to separate the casting template 4 from the cast wind turbine base when demoulding, so that the demoulding upward speed of the wind turbine base is not affected by the contact interference of the casting template 4, effectively improving the demoulding speed of the wind turbine base, and is easy to use.

[0023] The working principle of a wind turbine base rapid demolding device provided by the utility model is as follows: when the device is used to cast and mold the wind turbine base of a small wind turbine, firstly, the casting raw material is filled into the mold cavity formed between the casting template 4 and the demolding seat 10 through the external conveying original part. After the casting raw material is filled, it is cooled and molded statically, thereby realizing the preliminary molding of the wind turbine base. Then, the single chip computer 2 starts the motor 552 so that its output shaft drives the driving shaft to rotate forwardly. The driving shaft is meshed and connected through the gears 553, so that the threaded barrel 51 is reversed. The threaded barrel 51 is connected from the threaded barrel 51 through the threaded connection. The stud 1 52 drives the top seat 53 to move upward, and the telescopic end of the limiting telescopic rod 54 extends out with the top seat 53, thereby preventing the top seat 53 from rotating during the vertical movement. During the upward movement of the top seat 53, the threaded cylinder 1 51 is driven by the belt between the pulley 57 and the belt 58 to rotate the rightmost shaft 561. The two pulleys 57 have different diameters to avoid interference with the belt transmission. The rightmost shaft 561 is meshed and connected with the outer gear ring 563 through the gear 2 564 at the lower end, so that the remaining shafts 561 rotate synchronously. The shafts 561 are connected by the bevel gear 5 The meshing connection between 67 makes the threaded barrel 2 565 rotate synchronously, and the threaded barrel 2 565 is threadedly connected so that the stud 2 566 drives the casting template 4 to move to the end away from the center of the casting outer mold shell 1, so that the casting template 4 is automatically separated from the outer side of the cast wind turbine base. In this process, the telescopic end of the telescopic rod 3 moves with the casting template 4 adaptively. When the top seat 53 moves up to a certain extent, the top seat 53 contacts the contact seat 7. As the top seat 53 continues to move up, the contact seat 7 allows the demolding seat 10 to drive the cast wind turbine base in the mold to be quickly separated. Move vertically upward to demould the cast-molded wind turbine base, and the self-rotation of the demoulding base 10 during the vertical movement is avoided by the guiding telescopic rod 11. During this process, the casting template 4 is away from the cast-molded wind turbine base, and there is no contact obstruction between the two. During the upward movement of the cast-molded wind turbine base, the elastic contraction of the spring 9 and the friction or hydraulic resistance of the elastic elements and the bearing elements inside the damper 8 can release the external vibration interference force received by the cast-molded wind turbine base during the upward movement as heat energy, thereby improving the demoulding stability of the cast-molded wind turbine base.

[0024] It is worth noting that the single chip microcomputer 2 disclosed in the above embodiment can adopt COP8CBE9, the motor 552 can adopt Y90S-2, and the single chip microcomputer 2 controls the operation of the motor 552 using methods commonly used in the prior art.
