[0002] The wind turbine hub is a key component of a wind turbine generator set. It is located at the top of the wind turbine tower and connects the blades and main shaft of the wind turbine. Its main function is to convert wind power into mechanical energy through the wind wheel, and transmit the mechanical energy to the generator for power generation. With the development of wind power generation technology, the design and manufacturing of wind turbine hubs are gradually developing towards higher efficiency, lightweight and strong durability. It is not only the key to the efficient operation of wind turbines, but also a key component for realizing the utilization of renewable energy and promoting global energy transformation.

In the process of drilling holes in the wind turbine hub, the wind turbine hub to be drilled is first fixed on the top of the placement table 10 so that the surface to be drilled is directly opposite to the bottom of the drilling component 7. After the wind turbine hub is fixed, the movable frame 1 2 can be controlled to start, drive the column 1 3 and the top frame 4 to move to a suitable position, and then the position of the drilling component 7 is further adjusted by moving the movable frame 2 5 left and right. Finally, the drilling component 7 can be driven to move downward by the movable frame 3 6, so as to perform drilling operations on the wind turbine hub; The drilling assembly 7 includes a fixed plate 701, which is fixedly mounted on one side of the mobile frame 3 6, a motor 1 702 is fixedly mounted on the top surface of the fixed plate 701, a drill bit 703 is arranged at the output end of the motor 1 702, a protective sleeve 713 is fixedly mounted inside the fixed plate 701, the drill bit 703 is rotatably mounted inside the protective sleeve 713, the output end of the motor 1 702 extends to the inside of the protective sleeve 713, and is fixedly connected to one end of the drill bit 703, a guide block 714 is fixedly mounted on the outer surface of the protective sleeve 713, and the guide block 714 is arranged in a conical shape, and the drilling assembly 7 is arranged for drilling holes in the wind turbine hub; L-shaped frames 707 are fixedly installed on both sides of the fixed plate 701, and a protective cover 708 is fixedly installed on the bottom end of the L-shaped frame 707. A motor 2 705 is arranged on one side of the motor 1 702, and the motor 2 705 is fixedly installed with the motor 1 702 through an external plate 704. A toothed disc 709 is rotatably installed inside the protective cover 708, and a circular disc 710 is fixedly installed on the inner wall of the toothed disc 709. A circular disc frame 720 is rotatably installed on the bottom surface of the circular disc 710, and a plurality of inclined grooves are opened through the top surface of the circular disc 710. 711, the interiors of the multiple inclined grooves 711 are movably connected with a clamping column 712, the inner wall of the disc frame 720 is fixedly installed with a multiple guide frame 716, the number of the multiple guide frames 716 corresponds to the number of the clamping columns 712, the interiors of the multiple guide frames 716 are movably connected with a movable plate 717, one end of the multiple movable plates 717 is fixedly installed with a pressure plate 719, the outer surface of the guide block 714 is fixedly installed with a circular blade 715, and one end of the clamping column 712 is fixedly installed on the top surface of the movable plate 717.

[0023] During operation, in the process of drilling a hole in the wind turbine hub, that is, when the moving frame 3 6 moves downward, by controlling the motor 1 702 and the motor 2 705 to rotate, when the motor 1 702 rotates, the drill bit 703 can be driven to rotate. When the drill bit 703 fits the outer surface of the wind turbine hub, the drilling operation of the wind turbine hub can be achieved. In addition, when the motor 2 705 rotates, the gear 1 706 can be driven to rotate. Since the gear 1 706 and the toothed disc 709 are meshed with each other, the toothed disc 709 can be driven to rotate, thereby driving the circular disc 710 to rotate. When the circular disc 710 rotates, it can be driven under the action of the clamping column 712 and the inclined groove 711. The four movable plates 717 are driven to move synchronously inside the guide frame 716, that is, the four pressure plates 719 are driven to move synchronously in the direction of the circular blade 715. As the drilling progresses, some long strips of debris will be guided by the guide block 714 to enter between the circular blade 715 and the pressure plate 719, and when the four pressure plates 719 are in contact with the outer surface of the circular blade 715, the long strips of debris will be cut off. When the gear 1 706 rotates in the opposite direction driven by the motor 2 705, it can drive the four pressure plates 719 away from the circular blade 715, so that the long strips of debris can enter between the circular blade 715 and the pressure plate 719.

[0024] Through the above, the long strips of debris drilled out by the drill bit 703 during drilling can be effectively and automatically cut off, thereby achieving the purpose of being able to cut off the debris, so that during the drilling process, the outer surface of the drill bit 703 will not accumulate a lot of long strips of debris, and the problem of too many long strips of debris gathering on the outer surface of the drill bit 703 during the drilling process will be avoided, thereby improving the subsequent drilling effect and drilling accuracy, and avoiding the problem of the drill bit 703 being damaged due to too many entangled long strips of debris, thereby providing good protection for the drill bit 703.

[0025] The cooling assembly 11 includes a circular cylinder 1101 . There are two circular cylinders 1101 . The two circular cylinders 1101 are symmetrically arranged on both sides of the fixing plate 701 . The cooling assembly 11 is used to cool the drill bit 703 .

[0026] The inside of the circular cylinder 1101 is movably connected with a plug disc 1102, the outer surface of the circular cylinder 1101 is fixedly connected with a delivery pipe 1105, the outer surface of the delivery pipe 1105 is fixedly installed with a one-way valve 1106, one end of the one-way valve 1106 is fixedly connected to a fixing frame 1108, one side surface of the two fixing frames 1108 is obliquely installed with a nozzle 1109, the two nozzles 1109 are respectively installed on the bottom surfaces of two symmetrical movable plates 717, one side surface of the two circular cylinders 1101 is fixedly connected with a connecting pipe 1103, the outer surface of the connecting pipe 1103 is fixedly installed with a one-way valve 1104, the other end of the connecting pipe 1103 extends to the interior of the mixing box 9, a connecting rod 1107 is fixedly connected between the plug disc 1102 and the corresponding movable plate 717, the inner opening of the column 3 A clamping groove 1111 is provided, and a clamping rod 1112 is movably clamped inside the clamping groove 1111. A circular cylinder 1110 is provided inside the column 13, and a plug disc 1117 is movably clamped inside the circular cylinder 1110. A column 1118 is fixedly installed on the top surface of the plug disc 1117, and one end of the column 1118 is fixedly connected to the bottom surface of the clamping rod 1112. The outer surface of the circular cylinder 1110 is respectively fixedly connected with a liquid inlet pipe 1113 and a liquid outlet pipe 1115, and the outer surfaces of the liquid inlet pipe 1113 and the liquid outlet pipe 1115 are respectively installed with a one-way valve 3 1114 and a one-way valve 4 1116, one end of the liquid inlet pipe 1113 extends to the interior of the coolant tank 8, and one end of the liquid outlet pipe 1115 extends to the interior of the mixing tank 9, wherein the circular cylinder 1101 is fixedly installed on one end of the clamping rod 1112.

[0027] During operation, before drilling, it is necessary to calibrate the operating status of the drilling assembly 7, that is, to conduct a trial run. During the trial run, when the drilling assembly 7 as a whole moves up and down driven by the movable frame 3 6 for debugging, it can drive the circular cylinder 1101 to move up and down synchronously, and then drive the clamping rod 1112 to move downward inside the clamping groove 1111. When the clamping rod 1112 moves downward, it can drive the column 2 1118 to move downward, thereby driving the plug disc 2 1117 to move downward. When the clamping rod 1112 moves upward, it can drive the column 2 1118 to move upward, and can synchronously drive the plug disc 2 1117 to move upward inside the circular cylinder 2 1110. As the plug disc 2 1117 moves up and down inside the circular cylinder 2 1110, the coolant inside the coolant tank 8 can be sucked into the interior of the circular cylinder 2 1110 through the liquid inlet pipe 1113, and then discharged into the mixing box 9 through the liquid outlet pipe 1115. The interior of the mixing box 9 allows the coolant to gather and be stored in the mixing box 9. During the drilling process, since the movable plate 717 can move back and forth during the drilling process, it can drive the plug plate 1102 to move back and forth in the circular cylinder 1101, so that the coolant in the mixing box 9 is sucked into the interior of the circular cylinder 1101 through the connecting pipe 1103, and then discharged into the interior of the fixed frame 1108 through the delivery pipe 1105, and finally sprayed toward the drill bit 703 through the nozzle 1109, thereby effectively cooling the drill bit 703 and improving the drilling effect. It is also possible to cool the drilled long strips of debris. The hardness of the high-temperature debris will be significantly improved after cooling, ensuring that the long strips of debris can be more easily cut by the pressure plate 719 and the circular blade 715, thereby improving the cutting effect of the pressure plate 719 and the circular blade 715 on the long strips of debris.

[0028] Furthermore, since the two fixing frames 1108 are fixedly mounted on the bottom surfaces of the two symmetrical movable plates 717, the movable plates 717 can drive the fixing frames 1108 to move synchronously during their back-and-forth movement, so that the positions of the fixing frames 1108 are no longer fixed, thereby increasing the coverage area of ​​the coolant and further improving the cooling effect of the coolant.

The feeding component 12 includes a storage box 1201. A leakage pipe 1202 is fixedly connected to the bottom surface of the storage box 1201. A discharge pipe 1203 is fixedly connected to one side of the leakage pipe 1202. One end of the discharge pipe 1203 extends to the interior of the mixing box 9. A sealing plate 1204 is movably inserted into the interior of the leakage pipe 1202.

[0030] During operation, when the clamping rod 1112 moves up and down, it can also drive the tooth plate 13 to move synchronously inside the clamping groove 1111, thereby driving the gear 2 16 and the rotating shaft 15 to rotate bidirectionally inside the mounting frame 14, thereby driving the connecting shaft 2 17 to move synchronously. When the winding roller 18 rotates, the winding rope 19 can be wound up. During the winding process of the winding rope 19, since the winding rope 19 is also wound around the winding roller 2 1210 at the same time, it can drive the connecting shaft 1209 to rotate, thereby driving the turntable 1206 to rotate. That is, when the connecting shaft 2 17 rotates bidirectionally, it can drive the winding roller 2 1210 to rotate synchronously. Rotation, thereby driving the connecting shaft 1209 to rotate synchronously, so that the turntable 1206 can drive the sealing plate 1204 to move up and down inside the leakage pipe 1202 under the action of the connecting rod 2 1205. During the movement, the discharge pipe 1203 can be blocked and opened. In this process, the hardener inside the storage box 1201 can be intermittently discharged into the interior of the mixing box 9, mixed with the coolant entering the mixing box 9, and discharged at the same time as the coolant. When the hardener contacts the long strips of debris, the hardness of the long strips of debris can be further improved, thereby further improving the cutting effect of the pressure plate 719 and the circular blade 715 on the long strips of debris.

[0031] Two guide rails 1 20 and 21 are fixedly installed inside the coolant tank 8 and the mixing tank 9 respectively, a spring 22 is fixedly connected between the two guide rails 21, the outer surfaces of the guide rails 1 20 and 21 are movably connected with a clamping frame 23, a support 24 is fixedly installed on the top of the clamping frame 23, a connecting plate 26 is arranged above the guide rails 1 20 and 21, a connecting plate 1 25 is movably connected between the connecting plate 26 and the support 24, the connecting plate 26 inside the mixing tank 9 is fixedly sleeved on the outer surface of the winding rope 19, the connecting plate 26 inside the coolant tank 8 is fixedly connected to one end of the winding rope 19, extension rods 27 are fixedly installed on the two side surfaces of the clamping frame 23, a dial plate 28 is fixedly installed on one end of the extension rod 27, and a plurality of through holes 29 are opened inside the dial plate 28.

[0032] During operation, when the winding rope 19 is wound, it can drive the connecting plate 26 inside the coolant tank 8 and the mixing box 9 to move upward synchronously. During the movement, the angle between the connecting plate 1 25 and the guide rails 1 20 and 21 can be increased, thereby driving the clamping frame 23 to move inside the guide rails 1 20 and 21, and then the extension rod 27 and the paddle plate 28 can move synchronously, causing the paddle plate 28 to paddle the liquid inside the coolant tank 8 and the mixing box 9. On the one hand, the coolant inside the coolant tank 8 can be mixed more completely, and on the other hand, the coolant and the hardener inside the mixing box 9 can be completely mixed. The setting of the spring 22 can keep the winding rope 19 in a taut state at all times. When the paddle plate 28 inside the mixing box 9 is paddled, the hardener is intermittently added to the mixing box 9, thereby further improving the mixing effect of the coolant and the hardener inside the mixing box 9.

[0033] Specifically, the working process or working principle of the positioning and drilling device for the wind turbine hub is as follows: when in use, in the process of drilling the wind turbine hub, the wind turbine hub that needs to be drilled is first fixed on the top of the placement table 10, so that the surface that needs to be drilled is directly opposite to the bottom of the drilling component 7. After the wind turbine hub is fixed, it can be started by controlling the movable frame 2 to drive the column 1 3 and the top frame 4 to move to the appropriate position, and then the position of the drilling component 7 is further adjusted by moving the movable frame 2 5 left and right, and finally the drilling component 7 can be driven downward by the movable frame 3 6 to perform drilling operations on the wind turbine hub.

[0034] During the process of drilling a hole in the wind turbine hub, when the motor 2 705 rotates, it can drive the gear 1 706 to rotate. Since the gear 1 706 and the toothed disc 709 are meshed with each other, the toothed disc 709 can be driven to rotate, thereby driving the circular disc 710 to rotate. When the circular disc 710 rotates, it can drive the four movable plates 717 to move synchronously inside the guide frame 716 under the action of the clamping column 712 and the inclined groove 711, that is, it drives the four pressure plates 719 to move synchronously in the direction of the circular blade 715. As the drilling progresses, some long strips of debris will be guided by the guide block 714 to enter between the circular blade 715 and the pressure plate 719, and when the four pressure plates 719 are in contact with the outer surface of the circular blade 715, the long strips of debris will be cut off.

[0035] During the trial operation, when the drilling assembly 7 as a whole moves up and down for debugging driven by the movable frame three 6, it can drive the circular cylinder one 1101 to move up and down synchronously, and then drive the clamping rod 1112 to move downward inside the clamping groove 1111, and can suck the coolant inside the coolant tank 8 into the interior of the circular cylinder two 1110 through the liquid inlet pipe 1113, and then discharge it into the interior of the mixing box 9 through the liquid outlet pipe 1115, so that the coolant can gather and be stored inside the mixing box 9. During the drilling process, since the movable plate 717 can move back and forth during the drilling process, the coolant inside the mixing box 9 is sucked into the interior of the circular cylinder one 1101 through the connecting pipe 1103, and then discharged into the interior of the fixed frame 1108 through the delivery pipe 1105, and finally sprayed toward the drill bit 703 through the nozzle 1109, so that the drill bit 703 can be effectively cooled, thereby improving the drilling effect.

[0036] When the clamping rod 1112 moves up and down, it can also drive the tooth plate 13 to move synchronously inside the clamping groove 1111, thereby driving the gear 2 16 and the rotating shaft 15 to rotate bidirectionally inside the mounting frame 14, thereby driving the connecting shaft 2 17 to move synchronously. When the winding roller 18 rotates, the winding rope 19 can be wound up. During the winding process of the winding rope 19, since the winding rope 19 is also wound around the winding roller 2 1210 at the same time, it can drive the connecting shaft 1209 to rotate, thereby driving the turntable 1206 to rotate. That is, when the connecting shaft 2 17 rotates bidirectionally, it can drive the winding roller 2 1210 to rotate synchronously. , thereby driving the connecting shaft 1209 to rotate synchronously, so that the turntable 1206 can drive the sealing plate 1204 to move up and down inside the leakage pipe 1202 under the action of the connecting rod 2 1205. During the movement, the discharge pipe 1203 can be blocked and opened. In this process, the hardener inside the storage box 1201 can be intermittently discharged into the interior of the mixing box 9, mixed with the coolant entering the mixing box 9, and discharged at the same time as the coolant. When the hardener contacts the long strips of debris, the hardness of the long strips of debris can be further improved, thereby further improving the cutting effect of the pressure plate 719 and the circular blade 715 on the long strips of debris.

[0037] It should be noted that motor 1 702 and motor 2 705 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
