Description

Technical Field

[0001] The present invention relates to the technical field of wind turbine blade grinding, and in particular to an adaptive and adjustable wind turbine blade grinding device and a method thereof. Background Art

[0002] Wind turbine blades are important components of wind turbine generators. Wind power is used to rotate the blades to generate electricity. During the production process, wind turbine blades need to be polished to reduce their wind resistance. During the polishing process, both sides of the wind turbine blades need to be polished to ensure their working efficiency. Special polishing equipment is needed during the polishing process. However, the existing polishing equipment still has certain usage defects during use. When the elastic parts inside the existing polishing equipment contract, the elastic parts apply a greater force to the wind turbine blades, and the lower position of the wind turbine blades is polished. When the elastic parts are reset, the force applied to the wind turbine blades is smaller, resulting in uneven force application to the wind turbine blades, poor polishing effect, and excessive polishing of the higher positions of the wind turbine blades.

[0003] The patent with the authorization announcement number CN117359447A discloses an intelligent processing equipment for wind turbine blades and a wind turbine blade processing process. By setting a fitting groove matching the wind turbine blade, when the fitting rod is in the fitting groove, multiple movable rods and rotating rods can be located at different heights and matched with the shape of the wind turbine blade, so that the grinding belt fits the surface of the wind turbine blade when it is against the wind turbine blade. Since the fitting rod, movable rod and rotating rod can adjust the height according to the shape of the fitting groove, the force at different positions of the grinding belt is consistent, and the force applied by the grinding belt to different positions of the wind turbine blade is consistent, and the irregular surface of the wind turbine blade is polished more evenly, and the higher height positions of the wind turbine blade are prevented from being over-polished, and the grinding quality is better. In addition, the shape of the grinding belt can change with the curved surface of the wind turbine blade, and the contact area between the grinding belt and the wind turbine blade is large, and the grinding efficiency of the wind turbine blade is high.

[0004] The patent authorization announcement number CN213889455U discloses a wind turbine blade grinding device. An axial moving mechanism and a grinding head are provided on the base. The axial moving mechanism includes an X-axis moving component, a Y-axis moving component and a Z-axis moving component. The grinding head is fixed on the axial moving mechanism. An infrared scanning imaging module and a display are also provided on the base. The infrared scanning imaging module is used to scan the defective area profile of the blade surface and automatically form a curved surface grinding path, so that the grinding equipment is adsorbed on the blade surface through the base. First, the center layer of the defective area on the blade surface is ground and surveyed to confirm the number of layers. Then, the defective area profile is infrared scanned to form a grinding path, and then the staggered layers are automatically ground according to the layer specifications and number of layers of the defective area.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1: This example Figure 1-Figure 3 and Figure 8 As shown, in order to solve the problem that existing grinding equipment requires external equipment to flip the blades, the process of automatically flipping the wind turbine blades by the grinding equipment is disclosed, so that the grinding equipment can improve the grinding efficiency. The specific content is as follows: The base 1 and the support frame 2 are arranged on the upper end of the base 1; a driving structure 3 is provided on the outer side of the support frame 2, and a grinding structure 4 is provided at the lower end of the driving structure 3, a support plate 5 is provided on the upper end of the base 1, and two groups of flip plates 6 are rotatably installed on the upper end of the support plate 5, and a placement slot 7 is opened inside the flip plate 6; the upper end of the base 1 is provided with a limiting structure for controlling the flipping of the flip plate 6, a limiting structure hydraulic push rod 14 and an arc limiting rod 15, and the hydraulic push rod 14 is rotatably installed between the base 1 and the flip plate 6, and the arc limiting rod 15 is fixedly installed on the upper end of the support plate 5, and at the same time, the arc limiting rod 15 is slidably connected with the two groups of flip plates 6, the center of the arc limiting rod 15 and the center of the rotation position of the two groups of flip plates 6 are within the same straight line, and the two groups of flip plates 6 are rotatably connected, and the upper end surfaces of the two groups of flip plates 6 are not in the same horizontal plane.

[0022] When using the adaptive adjustable wind turbine blade grinding device, first place the device at the position where the work needs to be done. After the grinding device is placed at the required position, the wind turbine blade can be ground. During the grinding process, the wind turbine blade to be ground needs to be placed at the upper end of the placement slot 7. Figure 1, then the upper end of the wind turbine blade can be polished by the polishing structure 4, and during the polishing process, the polishing structure 4 can be driven by the driving structure 3 to move to realize polishing of different positions of the blade, and after the polishing of the wind turbine blade is completed, the wind turbine blade can be flipped by the docking and flipping between the two sets of flip plates 6, and the unpolished side is located at the upper end. In this process, two sets of hydraulic push rods 14 need to work, and the operation of the two sets of hydraulic push rods 14 will cause the two sets of flip plates 6 to rotate and approach each other, and the rotation angle of the flip plate 6 without blades needs to be greater than the flip plate 6 with blades placed, to prevent the blades inside the flip plate 6 from falling out, and the operation of the hydraulic push rod 14 will cause the two sets of flip plates 6 to rotate. After docking, the flip plate 6 on which the blades are placed can continue to rotate so that the flip plate 6 rotates to the upper end of the other set of flip plates 6, and at the same time, the hydraulic push rod 14 will continue to cooperate with the movement of the flip plate 6, so that the half-polished blade can fall to the outside of the other set of flip plates 6, thereby completing the flipping process of the blade by the grinding equipment. During the flipping process, the two sets of flip plates 6 can be limited by the arc-shaped limit rod 15 to ensure the accuracy of the flipping and docking of the two sets of flip plates 6, and after the flipping is completed, the support frame 2 will drive the driving structure 3 and the grinding structure 4 to move to the upper end of the wind turbine blade, and continue to grind the blade, thereby completing the flipping and grinding process of the blade by the grinding equipment, effectively improving the efficiency of the wind turbine blade grinding.

[0023] Example 2: This example Figure 1-Figure 7 As shown, in order to solve the problem of limited grinding accuracy of existing grinding equipment, the specific grinding process of the grinding equipment is disclosed, and the grinding equipment can achieve the effect of accurately completing grinding. The specific contents are as follows: The upper end of the base 1 is provided with a power structure for controlling the movement of the support frame 2. The driving structure includes a driving motor 8, and the driving motor 8 is fixedly mounted on the upper end of the base 1, and the output end of the driving motor 8 is fixedly mounted with an output shaft 9, and the output shaft 9 is rotatably connected to the base 1, and the outer side of the output shaft 9 is fixedly mounted with a main bevel gear 10, and the outer side of the main bevel gear 10 is meshed with a slave bevel gear 11, and a threaded rod 12 is fixedly mounted on the outer side of the slave bevel gear 11, and the threaded rod 12 is rotatably mounted on the upper end of the base 1, and the threaded rod 12 is threadedly connected to the lower end of the support frame 2, the guide rod 13 fixedly mounted on the upper end of the base 1 is slidably connected to the support frame 2, and a roller is provided inside the lower end of the support frame 2, and the support frame 2 A docking slide bar 25 is fixedly installed on the outside, a fixed frame 19 is fixedly installed on the upper end of the base 1, and a lifting block 20 is slidably installed inside the fixed frame 19, and a sliding block 24 is rotatably installed on the lower end of the lifting block 20, and the sliding block 24 is slidably installed on the upper end of the base 1, and a lower air cavity 21 is fixedly installed on the upper end of the fixed frame 19, and a lower piston rod 22 is slidably installed inside the lower air cavity 21, and the lower piston rod 22 is fixedly connected to the lifting block 20, and an upper air cavity 16 is fixedly installed on the outside of the support plate 5, and an upper piston rod 17 is slidably installed inside the upper air cavity 16, and a clamping block 18 is fixedly installed on the end of the upper piston rod 17 away from the upper air cavity 16, and the clamping block 18 is engaged with the outer side of the flip plate 6.

[0024] When the adaptive adjustable wind turbine blade grinding device is used, the blade needs to be flipped by rotating between the two sets of flip plates 6, and after flipping, the position of the grinding structure 4 needs to be changed by moving the support frame 2. In this process, the driving motor 8 needs to work and drive the output shaft 9 to rotate, and the output shaft 9 will drive the slave bevel gear 11 to rotate through the main bevel gear 10 installed on its outside, and the rotation of the slave bevel gear 11 will cause the threaded rod 12 to rotate and drive the support frame 2 to move, and the lower end of the support frame 2 is rollingly connected to the base 1 through a roller, and the support frame 2 moves stably under the limit of the guide rod 13; according to Figure 4-Figure 5The movement of the sliding block 24 will push the lifting block 20 to move upward, and the lifting block 20 will push the lower piston rod 22 to move upward inside the lower air chamber 21 during the upward movement of the lifting block 20. At this time, the gas in the lower air chamber 21 can be transported to the interior of the upper air chamber 16 through the air pipe 23, and the gas inside the upper air chamber 16 will push the upper piston rod 17 to move. At this time, the upper piston rod 17 can drive the card block 18 to move and make the card block 18 engage with the flip plate 6, thereby limiting the flip plate 6 to the upper end of the support plate 5, avoiding deviation in the rotation of the support plate 5, and ensuring the accuracy of the blade grinding of the grinding equipment.

[0025] Example 3: This example Figure 1 and Figure 8-Figure 9 As shown, in order to solve the problem that existing grinding equipment can automatically separate wind turbine blades, the process of automatically ejecting the blades from the inside of the equipment is disclosed, so that the grinding equipment can be quickly separated from the wind turbine blades. The specific content is as follows: The upper end of the base 1 is provided with a jacking structure for controlling the lifting and lowering of the wind turbine blades. The jacking structure includes a hydraulic cylinder 26, and the hydraulic cylinder 26 is fixedly installed on the upper end of the base 1, and a lifting plate 27 is fixedly installed on the upper end of the hydraulic cylinder 26, and a jacking block 28 is fixedly installed on the upper end of the lifting plate 27, and a ejector 29 is fixedly installed on the upper end of the jacking block 28, and the jacking block 28 is located inside the flip plate 6.

[0026] When using the adaptive adjustable wind turbine blade grinding device, the wind turbine blade needs to be placed inside the placement slot 7 for grinding, and after the grinding is completed, the wind turbine blade needs to be taken out from the placement slot 7. Figure 9 At this time, the hydraulic cylinder 26 will push the lifting plate 27 upward, and the lifting plate 27 will move vertically upward under the action of the outer rod limiter. At this time, the lifting plate 27 can drive the jacking block 28 to move upward synchronously, and in the process of the jacking block 28 moving upward, the ejector 29 will eject the wind turbine blade inside the placement slot 7, thereby completing the automatic ejection process of the grinding equipment for the wind turbine blade, making it easier to remove the wind turbine blade from the inside of the equipment, ensuring the efficiency of the grinding equipment for the wind turbine blade grinding process, and increasing the overall practicality.
