The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0018] Embodiment 1 See also Figure 1-Figure 19 The present invention provides a technical solution: a wind turbine brake disc spray protection device, comprising a workbench 1, and a first conveyor group 8 and a second conveyor group 10 installed on the outer wall of the workbench 1, a brake disc 9 is placed on the surface of the first conveyor group 8, an electric slide rail 2 is fixedly connected to the outer wall of the workbench 1, an electric slider 3 is slidably connected to the outer wall of the electric slide rail 2, a connecting frame 4 is fixedly connected to the outer wall of the top of the electric slider 3, a lifting plate 5 is slidably connected to the outer wall of one side of the connecting frame 4, and a lifting plate 5 adapted to the lifting plate 5 is provided on the outer wall of the connecting frame 4 Hydraulic cylinder 7, a drying chamber 12 adapted for the brake disc 9 is provided on the position of the workbench 1 above the second conveyor group 10, a spraying assembly 6 for spraying the brake disc 9 is provided on the side of the lifting plate 5 close to the workbench 1, the spraying assembly 6 includes a grabbing block 601, an injection groove 642 is provided on the inner wall of the grabbing block 601, and a main nozzle 643 adapted for the injection groove 642 is provided on the side of the grabbing block 601 close to the brake disc 9; a support assembly 11 for limiting the brake disc 9 is provided on the outer wall of the second conveyor group 10.

[0019] When in use, the brake disc 9 is first conveyed to the bottom of the lifting plate 5 through the first conveyor group 8, and then the hydraulic cylinder 7 is started to push the lifting plate 5 to move downward on the surface of the connecting frame 4, so that the grab block 601 moves to the surface of the brake disc 9, and the brake disc 9 can be grabbed. After that, the hydraulic cylinder 7 pulls the lifting plate 5 to move upward on the surface of the connecting frame 4, so that the brake disc 9 is separated from the first conveyor group 8 and drives it to rotate, and then the spraying material is injected into the inside of the injection groove 642 through the external pipeline, so that the spraying material is sprayed from the main nozzle 643 to the surface of the brake disc 9. When one side of the brake disc 9 is sprayed, the spraying assembly 6 will drive the brake disc 9 to rotate. After the two sides of the brake disc 9 are sprayed, the electric slider 3 slides on the surface of the electric slide rail 2 to move the connecting frame 4 to the top of the second conveyor unit 10, and then the hydraulic cylinder 7 pushes the lifting plate 5 to move downward on the surface of the connecting frame 4, so that the grab block 601 moves to the top of the support assembly 11, so that the support assembly 11 can limit the support of the brake disc 9 to prevent the sprayed surface of the brake disc 9 from touching the second conveyor unit 10, and finally the second conveyor unit 10 drives the movement of the support assembly 11 to transport the brake disc 9 into the drying chamber 12 for drying.

[0020] See also Figure 3 , Figure 4 , Figure 5 and Fig.14 The spraying assembly 6 also includes a servo motor 602, a recovery mechanism, a grabbing and flipping mechanism, and an auxiliary spraying mechanism. The servo motor 602 is installed inside the grab block 601. A connecting shaft 603 is rotatably connected to the outer wall of one end of the servo motor 602. A connecting rod 604 is rotatably connected to the outer wall of one end of the connecting shaft 603. A rotating column 608 is rotatably connected to the outer wall of one end of the connecting rod 604. The outer wall of the rotating column 608 is rotatably connected to the grab block 601. An air chamber 609 is provided on the inner wall of the rotating column 608. The connecting rod 60 4 is provided with an extrusion plate 610 adapted to the air bin 609, the inner wall of the rotating column 608 is provided with a through groove 611 adapted to the air bin 609, the inner wall of the through groove 611 is slidably connected with a push rod 612, a slider 613 is fixedly connected to the outer wall of one end of the push rod 612, a first limit block 614 is fixedly connected to the outer wall of one end of the slider 613, a sliding groove 615 adapted to the slider 613 is provided on the outer wall of the bottom end of the rotating column 608, and a fixing spring 616 adapted to the push rod 612 is provided on the inner wall of the rotating column 608.

[0021] When in use, when the grab block 601 moves to the surface of the brake disc 9, the first limit block 614 will enter the inside of the connection port on the surface of the brake disc 9. At this time, the external power supply is connected, the servo motor 602 is started, and the connecting shaft 603 is driven to rotate counterclockwise. When the connecting shaft 603 rotates, the connecting rod 604 is driven to rotate synchronously, thereby driving the extrusion plate 610 to slide inside the air chamber 609 and squeeze the air inside the air chamber 609, so that the air inside the air chamber 609 is squeezed into the inside of the through groove 611, thereby pushing the push rod 612 to slide inside the through groove 611 and squeeze the fixed spring 616, and the push rod 612 is When the through groove 611 slides inside, it will push the slider 613 to slide on the surface of the slide groove 615, which can push the multiple groups of first limit blocks 614 to slide outward, thereby squeezing the connecting port on the surface of the brake disc 9, thereby fixing the brake disc 9, and pulling the lifting plate 5 upward on the surface of the connecting frame 4 through the hydraulic cylinder 7, so that the brake disc 9 is separated from the first conveyor group 8, and then the servo motor 602 continues to drive the connecting shaft 603 to rotate counterclockwise. When the connecting shaft 603 rotates, it drives the rotating column 608 to rotate synchronously through the connecting rod 604, thereby driving the brake disc 9 to rotate and cooperate with the main nozzle 643 to complete the spraying operation.

[0022] See also Figure 4 , Figure 5 , Figure 6 , Fig.13 , Fig.14 , Fig.15 , Fig.16 and Fig.17The spraying assembly 6 also includes an empty chamber 605 provided on the inner wall of the connecting rod 604, and an air inlet groove 617 provided on the inner wall of the push rod 612. A blocking block 606 adapted to the empty chamber 605 is provided on the outer wall of one end of the connecting shaft 603. An air inlet 607 adapted to the empty chamber 605 is provided on the outer wall of the connecting rod 604. A connecting groove 618 adapted to the air inlet groove 617 is provided on the inner wall of the slider 613. A first limit spring 619 is fixedly connected to the inner wall of the connecting groove 618. A first baffle 620 is fixedly connected to the outer wall of one end of the first limit spring 619. A first groove 621 is provided on the outer periphery of the first baffle 620 along the circumferential direction. A first baffle 620 adapted to the first baffle 620 is provided on the inner wall of one end of the slide groove 615. A connecting sleeve 622, a through hole 623 is provided on the outer wall of one end of the connecting sleeve 622, an air inlet channel 624 adapted to the connecting sleeve 622 is arranged on the inner wall of the rotating column 608, a connecting spring 625 is fixedly connected to the inner wall of one end of the air inlet channel 624, a connecting plate 626 is fixedly connected to the outer wall of one end of the connecting spring 625, a limiting rod 627 passes through the surface of the connecting plate 626, a first connecting hole 628 adapted to the limiting rod 627 is provided on the inner wall of the grab block 601, a second connecting hole 629 adapted to the limiting rod 627 is provided on the outer wall of the connecting rod 604, an exhaust groove 630 adapted to the air inlet 607 is provided on the inner wall of the rotating column 608, and one end of the exhaust groove 630 is connected to the air inlet channel 624.

[0023] When the extrusion plate 610 squeezes the air inside the air chamber 609, one end of the limiting rod 627 is connected to the first connecting hole 628, thereby limiting the rotation column 608, ensuring that the extrusion plate 610 can completely push the air inside the air chamber 609 into the through groove 611, and at the same time, the connecting shaft 603 will drive the blocking block 606 to rotate synchronously inside the empty chamber 605, so that the blocking block 606 limits the air inlet 607. When the first limiting block 614 fixes the brake disc 9, the connecting sleeve 622 will slide into the connecting groove 61 8 and push the first baffle 620, so that the first baffle 620 slides inside the connecting groove 618 and squeezes the first limiting spring 619, thereby releasing the limit of the first groove 621. At this time, the air inside the through groove 611 enters the inside of the connecting groove 618 through the air inlet groove 617, and then passes through the first groove 621 and the through hole 623 on the surface of the first baffle 620 to enter the inside of the connecting sleeve 622, and finally enters the inside of the air inlet channel 624 and squeezes the surface of the connecting plate 626, thereby pushing the connecting plate 626 to The air inlet channel 624 slides inside and squeezes the connecting spring 625. The movement of the connecting plate 626 can drive the limiting rod 627 to slide inside the grab block 601, so that one end of the limiting rod 627 slides out of the first connecting hole 628 to release the limit on the rotating column 608. At the same time, the other end of the limiting rod 627 slides into the second connecting hole 629, so that the connecting rod 604 limits the rotating column 608. When the servo motor 602 drives the connecting shaft 603 to rotate clockwise, it will drive the blocking block 606 to rotate synchronously. The air in the through groove 611 can be drawn back into the air bin 609 by rotating the extrusion plate 610 in the clockwise direction inside the air bin 609. At the same time, the fixed spring 616 can push the push rod 612 to reset, so that the first limit block 614 can release the limit on the brake disc 9.

[0024] See also Figure 3 and Figure 7The recovery mechanism includes a transmission block 631 arranged on the outer wall of the connecting shaft 603, and a recovery box 637 arranged on the inner wall of the grab block 601. The outer wall of the transmission block 631 is rotatably connected with a transmission belt 632. The transmission block 631 is provided with a fan blade 633 at a position above the recovery box 637. The fan blade 633 is provided with a connection block 634 adapted to the transmission belt 632 on the side away from the recovery box 637. The inner wall of the grab block 601 is provided with a suction channel 635, and the suction channel 635 is provided with a suction channel 636. 5 is arranged above the recycling box 637, a suction port 636 adapted to the suction channel 635 is arranged on the outer wall of the bottom end of the grab block 601, an exhaust port 638 is opened between the recycling box 637 and the fan blade 633, a filter screen 639 is arranged on the inner wall of the exhaust port 638, an exhaust channel 640 adapted to the fan blade 633 is arranged on the inner wall of the grab block 601, and an exhaust port 641 adapted to the exhaust channel 640 is arranged on the outer wall of the bottom end of the grab block 601 on the side away from the suction port 636.

[0025] When the connecting shaft 603 rotates, it will drive the transmission block 631 to rotate synchronously, thereby driving the connecting block 634 to rotate synchronously through the transmission belt 632. Since the size of the dynamic transmission block 631 is larger than the size of the connecting block 634, the rotation speed of the connecting block 634 is faster than that of the transmission block 631, thereby driving the fan blade 633 to rotate at a high speed, so that the fan blade 633 draws air into the inside of the recovery box 637 through the exhaust port 638, thereby reducing the air pressure inside the recovery box 637, thereby generating a suction force, so that the air in the direction of the brake disc 9 The paint remaining after spraying is sucked into the recovery box 637 through the suction port 636 and the suction channel 635. After the paint and air are sucked into the recovery box 637, they enter the exhaust channel 640 through the exhaust port 638. During this process, the filter 639 filters the paint, thereby intercepting the paint into the recovery box 637. The air entering the exhaust channel 640 is blown toward the surface of the unpainted position of the brake disc 9 through the exhaust port 641, thereby cleaning the dust on the surface of the brake disc 9.

[0026] See also Figure 1 , Figure 7 , Figure 8 , Fig. 9 and Fig.10The grabbing and flipping mechanism includes a piston chamber 650 opened on the inner wall of the grabbing block 601, and electric push rods 644 installed on both sides of the grabbing block 601. A fixing block 645 is fixedly connected to the outer wall of the bottom end of the electric push rod 644. A connecting column 646 is rotatably connected to the inner wall of the fixing block 645. A grabbing ring 647 is fixedly connected to the outer wall of one end of the connecting column 646. A cavity 648 is opened on the inner wall of the fixing block 645. A fin 646 adapted to the cavity 648 is provided on the outer wall of the connecting column 646. 9. An electric cylinder 651 is installed on the inner wall of the piston chamber 650, and a piston plate 652 is fixedly connected to the outer wall of one end of the electric cylinder 651. An air injection groove 653 adapted to the piston chamber 650 is provided on the inner wall of the grab block 601, and a telescopic tube 654 adapted to the air injection groove 653 is provided on the outer wall of the grab block 601, and one end of the telescopic tube 654 is connected to the fixed block 645. A cylinder 655 is fixedly connected to the inner wall of the grab ring 647, and a fixed plate 656 is fixedly connected to the outer wall of one end of the cylinder 655.

[0027] During use, after one side of the brake disc 9 is sprayed, the cylinder 655 is started to push the fixing plate 656 to squeeze the brake disc 9, thereby fixing the brake disc 9, and then the electric push rod 644 is started to push the fixing block 645 and the grab ring 647 to move downward, so that the grab ring 647 is separated from the grab block 601, and then the electric cylinder 651 is started to push the piston plate 652 to slide inside the piston chamber 650, thereby squeezing the air inside the piston chamber 650 into the inside of the air injection groove 653, and then passing into the inside of the cavity 648 through the telescopic tube 654, thereby applying a thrust to the surface of the fin 649, causing the fin 649 to rotate inside the cavity 648, and driving the connecting column 646 to rotate. When the connecting column 646 rotates, it will drive the grab ring 647 to rotate synchronously, thereby realizing the turning over of the brake disc 9, and finally the electric push rod 644 contracts, pulling the grab ring 647 to reset, and the brake disc 9 can be fixed and sprayed again.

An auxiliary nozzle 658 adapted to the auxiliary injection groove 657 is arranged on the outer wall of one side of the grabbing ring 647. A second baffle 660 is fixedly connected to the outer wall of one end of the second limiting spring 659. A second groove 661 is arranged on the outer periphery of the second baffle 660 along the circumferential direction. A connecting sleeve 662 adapted to the injection groove 642 is arranged on the outer wall of the bottom end of the grabbing block 601. A receiving groove 663 adapted to the connecting sleeve 662 is arranged on the outer wall of the grabbing ring 647, and a top rod 664 adapted to the second baffle 660 is arranged on the inner wall of the receiving groove 663.

[0029] When spraying one side of the brake disc 9, the connecting sleeve 662 will enter the interior of the receiving groove 663, and the push rod 664 inside the receiving groove 663 will pass through the connecting sleeve 662 and enter the interior of the injection groove 642, so that the push rod 664 pushes the second baffle plate 660 to slide upward inside the injection groove 642 and stretch the second limit spring 659, so that the second baffle plate 660 fits with the inner wall of the injection groove 642, and the second groove 661 can be limited to prevent the paint from flowing out of the injection groove 642, and the brake disc 9 is turned over. After the surface is sprayed, the push rod 664 will slide out of the interior of the injection groove 642. At this time, the second limit spring 659 is forced to pull the second baffle 660 to reset, so that the limit on the second groove 661 can be released. When the grab ring 647 is closed with the grab block 601 again, the connecting sleeve 662 will be stuck in the interior of the auxiliary injection groove 657. When the reverse side of the brake disc 9 is sprayed, the paint will enter the interior of the auxiliary injection groove 657 from the injection groove 642 and be sprayed out from the auxiliary nozzle 658, so that the side of the brake disc 9 can be sprayed.

[0030] See also Fig.11 and Fig.12 The support assembly 11 includes a support column 1101 installed on the outer wall of the second conveyor unit 10, a second limit block 1102 is slidably connected to the inner wall of the top end of the support column 1101, an arc-shaped spring sheet 1103 adapted to the second limit block 1102 is arranged on the inner wall of the top end of the support column 1101, a pressing column 1104 is slidably connected to the inner wall of the support column 1101, and the top end of the pressing column 1104 extends out of the surface of the support column 1101, and the pressing column 1104 extends out of the support column A pressing block 1105 adapted to the second limit block 1102 is arranged on the outer wall at one end of the surface 1101, a limiting disc 1106 is fixedly connected to the outer wall at the bottom end of the pressing column 1104, a grab hook 1107 adapted to the limiting disc 1106 is arranged on the inner wall of the support column 1101, a spring sheet 1108 adapted to the grab hook 1107 is arranged on the inner wall of the support column 1101, and a return spring 1109 adapted to the limiting disc 1106 is arranged on the inner wall of the support column 1101.

[0031] When in use, after the brake disc 9 is sprayed, it is transported to the top of the support column 1101, and the pressing block 1105 passes through the connecting port on the surface of the brake disc 9 through the downward pressure of the grab block 601. The pressing block 1105 continues to move downward to press the pressing column 1104. The pressing column 1104 slides downward under the force and squeezes the return spring 1109. When the pressing column 1104 moves downward, the pressing block 1105 will squeeze the surface of the second limit block 1102, thereby pushing the second limit block 1102 to slide outward and stretch the arc-shaped spring sheet 1103, which can squeeze the connecting port on the surface of the brake disc 9, thereby fixing the brake disc 9. At the same time, the limiting disc 1106 will squeeze the grab block 601. The surface of hook 1107 causes the grab hook 1107 to rotate and squeeze the spring sheet 1108. After the limiting disc 1106 passes through the surface of the grab hook 1107, the force of the spring sheet 1108 pushes the grab hook 1107 to reset, thereby limiting the limiting disc 1106. When the brake disc 9 needs to be removed, it is only necessary to press one end of the grab hook 1107 to release the limit on the limiting disc 1106. At this time, the force of the reset spring 1109 pushes the pressing column 1104 to reset, thereby releasing the pressing block 1105 from pressing the second limiting block 1102, so that the arc-shaped spring sheet 1103 is forced to pull the second limiting block 1102 to reset and release the fixation of the brake disc 9.
