Description

Technical Field

[0001] The present invention relates to the technical field of wind turbine blade grinding, and in particular to a wind turbine blade grinding device that is easy to position and install, and a use method thereof. Background Art

[0002] Wind turbine blades refer to the core components of wind turbines that convert natural wind energy into electrical energy for wind turbines. Their function is to convert wind energy into mechanical energy, which in turn drives the generator to generate electricity. The material and manufacturing process of the blades also have an important impact on the performance and life of the wind turbine. The blades need to have sufficient strength and rigidity to withstand the impact and torsion of wind; at the same time, the surface smoothness and balance of the blades also need to be guaranteed to reduce wind resistance and vibration, and improve the stability and life of the generator. Therefore, the fineness of the surface polishing needs to be ensured during the processing of wind turbine blades, for example:

[0003] Publication No. CN205520837U discloses a wind turbine blade grinding device that has both the mobility of a mobile platform and the flexible operation of mechanical equipment, and can complete tasks that require both large-scale positioning and flexible operation. The existence of the mobile platform enhances the flexibility and operating range of the device, giving it an almost unlimited operating space;

[0004] Publication No. CN117067037A discloses a rapid positioning device for a wind turbine blade grinder and a method for using the same. By setting a processing box, dust and airflow are transferred to the inside of the processing box. Some impurities will fall into the dust collecting box as the airflow is reduced, and the remaining impurities will be purified and discharged by the processing box, which not only solves the problem of collecting dust, but also can purify the remaining gas.

[0005] However, the above-mentioned grinding device for wind turbine blades still has the following problems during actual use: although the blades are ground by a movable grinding mechanism, the actual wind turbine blades are relatively large in size, and the lateral span and longitudinal length cannot be adapted to the existing grinding device. The grinding device cannot be effectively fixed, and thus, it is easy for the curved wind turbine blades to be offset and misaligned. At the same time, the blades are usually in a horizontally lying state during processing, and the vertically arranged grinding mechanism and dust removal mechanism cannot be effectively adapted, thereby reducing the efficiency and precision of the grinding of the wind turbine blades.

[0006] Therefore, we proposed a wind turbine blade grinding device and a method of use that are easy to position and install, in order to solve the problem that although the existing grinding mechanism can grind the blades through a mobile mechanism, the actual wind turbine blades are relatively large in size, and the horizontal span and vertical length cannot be adapted to the existing grinding device. The grinding device cannot be effectively fixed, and thus, it is easy for the curved wind turbine blades to be offset and misaligned. At the same time, the blades are usually in a horizontally lying state during processing, and the vertically arranged grinding mechanism and dust removal mechanism cannot be effectively adapted, thereby reducing the efficiency and precision of grinding the wind turbine blades.

[0020] A method for using a wind turbine blade grinding device that is easy to position and install, comprising the following steps:

[0021] S1: First, the grinding platform and the bearing bracket are moved through the bottom positioning base and the symmetrically arranged moving guide wheels, and then adjusted according to wind turbine blades of different specifications and the positions to be polished. Then, when the grinding platform needs to be positioned and installed to the required position, the motor is connected to the bidirectional threaded rod inside the positioning base, so that the rotating bidirectional threaded rod drives the positioning tooth plates threaded on the front and rear sides of the outer wall to move inward synchronously, and then the front and rear positioning tooth plates are engaged with the outer wall of the positioning gear in the middle of the positioning shaft, so that the positioning gear and the positioning shaft cannot rotate, and the positioning shaft locks the moving guide wheel outside the positioning base to limit the position, so that the non-rotating moving guide wheel fixes the position of the bearing bracket and the grinding platform, thereby preventing displacement during the subsequent grinding process;

[0022] S2: After the grinding platform is positioned and installed, the bidirectional threaded rod arranged inside the positioning base drives the transmission shaft meshing and connected above to rotate through the bevel gear group in the middle during the rotation process, and then the transmission shaft drives the guide shaft arranged below the dust removal flip frame to rotate through the bevel gear group at the upper end, and then the dust removal flip frame is driven by the guide shaft to flip inward in the storage guide groove provided inside the supporting bracket, so that the dust removal flip frame drives the dust removal suction plate connected above by the reset spring to be arranged in an inclined state, so as to be more closely fitted to the top of the wind turbine blade, and then the dust is adsorbed during the subsequent grinding process;

[0023] S3: When adjusting the grinding range of the wind turbine blade, the guide threaded rod in the movable guide groove inside the grinding platform is connected to the servo motor, so that the rotating guide threaded rod drives the adjustment platform connected to the outer wall thread to move in the left and right directions, and at the same time, the guide slide needle penetrating the rear of the adjustment platform limits it, thereby preventing deviation during the adjustment process from affecting the grinding accuracy;

[0024] Furthermore, the driving member drives the driving gear above the adjustment platform to rotate, so that it drives the meshing driven gear and the lifting threaded rod in the middle to rotate, and the bottom end of the lifting sleeve threadedly connected to the lifting threaded rod is fixedly connected to the top surface of the grinder, so that the grinding machine can limit the rotation of the lifting sleeve, and then the lifting sleeve drives the grinder to adjust in the up and down direction, so as to adapt to the grinding of wind turbine blades of different models and specifications;

[0025] S4: When the grinder is grinding the wind turbine blade, the dust removal flip frame and the dust removal suction plate which are distributed in an inclined manner on the left and right sides are attached to the top of the wind turbine blade, and then the dust removal suction device arranged on the top of the supporting bracket is operated to suck the dust through the dust removal suction channel opened by the dust removal suction plate through the through-connected suction hose, so as to prevent the dust from grinding from spreading in the air and affecting the working environment;

[0026] Furthermore, when the sander moves in the left and right directions, the sander contacts the dust removal suction plate in the moving direction, so that the dust removal suction plate that is in contact squeezes the return spring inside the dust removal turning frame, and then the dust removal suction plate moves toward the inside of the dust removal turning frame to prevent affecting the movement and sanding work of the sander.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: the wind turbine blade grinding device and the use method that are easy to position and install, the positioning base and the movable guide wheel assist the grinding platform to move and lock the positioning installation, and the adjustment platform that can be lifted up and down and moved left and right drives the grinder to adapt to the wind turbine blade, and the dust removal flip frame and the dust removal suction plate are flipped and moved to adsorb dust in the subsequent grinding process, and the specific contents are as follows:

[0028] 1. The driving motor drives the bidirectional threaded rod to rotate, so that the threaded positioning tooth plate moves inward synchronously to engage with the positioning gear, thereby preventing the positioning gear and the positioning shaft from rotating, and the positioning shaft locks the movable guide wheel outside the positioning base to limit the position, so that the movable guide wheel that cannot rotate fixes the position of the bearing bracket and the grinding platform, thereby preventing deviation during the subsequent grinding process;

[0029] 2. The bidirectional threaded rod bevel gear group drives the transmission shaft and the guide shaft to rotate, and then the dust removal flip frame flips through the rotation of the guide shaft, and then flips inward in the storage guide groove opened inside the support bracket, so that the dust removal flip frame drives the dust removal suction plate connected to the upper part by the reset spring to be set in an inclined state, so as to fit more closely to the upper part of the wind turbine blade, and then absorb the dust in the subsequent grinding process;

[0030] 3. The guide threaded rod of the grinding platform drives the adjustment platform connected with the outer wall thread to move in the left and right directions, and then the driving gear rotates to engage the driven gear and the lifting threaded rod in the middle to rotate, and the bottom end of the lifting sleeve threadedly connected with the lifting threaded rod is fixedly connected to the top surface of the grinder, so that the grinding machine can limit the rotation of the lifting sleeve, and then the lifting sleeve drives the grinding machine to adjust in the up and down directions, so as to adapt to the grinding of wind turbine blades of different models and specifications;

[0031] 4. The dust removal flip frame and the dust removal suction plate distributed in an inclined manner are attached to the top of the wind turbine blades, and then the dust removal suction device arranged above the supporting bracket is operated to suck the dust through the dust removal suction channel opened on the dust removal suction plate through the through-connected suction hose to prevent the dust from grinding from spreading in the air and affecting the working environment.

Then, when the grinding platform (1) needs to be positioned and installed at the required position, the motor is connected to the bidirectional threaded rod (12) inside the positioning base (4), so that the rotating bidirectional threaded rod (12) drives the positioning tooth plates (13) threadedly connected to the front and rear sides of the outer wall to move inward synchronously, and then the front and rear side positioning tooth plates (13) are engaged with the outer wall of the positioning gear (14) in the middle of the positioning shaft (5), so that the positioning gear (14) and the positioning shaft (5) cannot rotate, and the positioning shaft (5) locks the moving guide wheel (11) outside the positioning base (4) to limit the position, so that the non-rotating moving guide wheel (11) fixes the position of the bearing bracket (2) and the grinding platform (1), thereby preventing deviation during the subsequent grinding process; S2: After the grinding platform (1) is positioned and installed, the bidirectional threaded rod (12) disposed inside the positioning base (4) drives the transmission shaft (26) meshingly connected above to rotate through the bevel gear group (27) in the middle during the rotation process, and then the transmission shaft (26) drives the guide shaft (10) disposed below the dust removal turning frame (9) to rotate through the bevel gear group (27) at the upper end, and then the dust removal turning frame (9) is driven by the guide shaft (10) to turn inward in the storage guide groove (3) provided inside the supporting bracket (2), so that the dust removal turning frame (9) drives the dust removal suction plate (22) connected above by the return spring (23) to be arranged in an inclined state, so as to be more closely fitted to the top of the wind turbine blade, thereby adsorbing dust in the subsequent grinding process; S3: When adjusting the grinding range of the wind turbine blade, the guide threaded rod (7) in the movable guide groove (6) inside the grinding platform (1) is connected to the servo motor, so that the rotating guide threaded rod (7) drives the adjustment platform (15) connected to the outer wall thread to move in the left and right directions, and at the same time, the guide sliding rod (8) connected through the rear of the adjustment platform (15) limits the position thereof, thereby preventing the deviation from affecting the grinding accuracy during the adjustment process; Furthermore, the driving member drives the driving gear (16) above the adjustment platform (15) to rotate, thereby driving the meshing driven gear (17) and the lifting threaded rod (18) in the middle to rotate, and the bottom end of the lifting sleeve (19) threadedly connected to the lifting threaded rod (18) is fixedly connected to the top surface of the grinder (20), so that the grinding machine (20) can limit the rotation of the lifting sleeve (19), thereby allowing the lifting sleeve (19) to drive the grinding machine (20) to adjust in the up and down direction, so as to adapt to the grinding of wind turbine blades of different models and specifications; S4: During the process of the grinder (20) grinding the wind turbine blade, the dust removal flip frame (9) and the dust removal suction plate (22) arranged in an inclined manner on the left and right sides are attached to the top of the wind turbine blade, and then the dust removal suction device (21) arranged above the supporting bracket (2) is operated to suck the dust through the dust removal suction channel (24) opened by the dust removal suction plate (22) through the through-connected suction hose (25), so as to prevent the dust from grinding from spreading in the air and affecting the working environment; Furthermore, when the sander (20) moves in the left-right direction, the sander (20) contacts the dust suction plate (22) in the moving direction, so that the dust suction plate (22) that is in contact squeezes the return spring (23) inside the dust removal flip frame (9), and then the dust suction plate (22) moves toward the inside of the dust removal flip frame (9) to prevent the movement and sanding work of the sander (20) from being affected.
