Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade maintenance technology, and in particular to a wind turbine blade maintenance device. Background Technology

[0002] Wind turbines use wind power to rotate windmill blades, and then use speed increasers to increase the rotation speed. Wind turbine blades are generally quite large and are usually installed at relatively high positions. Therefore, in order to ensure the normal operation of the wind power generation system, the condition of the wind turbine blades needs to be inspected before installation.

[0003] A search revealed that Chinese Patent Publication No. CN220487775U discloses a maintenance and repair device for wind turbine blades. The device includes a maintenance platform with limit rods at both ends of its inner wall. A stepper motor is mounted at one end of the platform, and a lead screw is attached to the output shaft of the stepper motor, passing through the inner wall of the platform. The end of the lead screw is rotatably connected to the inner wall of the platform. Two moving rods are threaded onto the external part of the lead screw, and each moving rod has a side that is slidably connected to the limit rod. Two sliding grooves are formed on the top of the maintenance platform. This device, through the stepper motor, allows users to use the motor to drive a first and second clamping device to clamp the fan blades, achieving initial fixation. Furthermore, the rotating mechanism causes a screw to move a soft top downwards, further pressing the fan blades in place, achieving secondary fixation. This effectively improves stability and prevents the blades from falling off during maintenance.

[0004] However, in the existing technology, the maintenance device for wind turbine blades usually uses a clamping frame that can hold the blade around its perimeter. However, each clamping frame requires an individual rotation of the knob on its top to move the clamping plate on the clamping frame so that the clamping plate clamps the outer surface of the blade. This process is cumbersome and involves a lot of repetitive work, which makes the maintenance of the blades inconvenient and reduces the efficiency of maintenance. A solution is proposed to solve the problems mentioned in the background technology. Utility Model Content

However, each clamping frame requires an individual rotation of a knob to move the clamping plate on the frame, thus clamping the plate onto the outer surface of the blade. This process is cumbersome and involves a lot of repetitive work, making blade maintenance inconvenient and reducing maintenance efficiency.

[0015] As a further description of the above technical solution: the bidirectional lead screw can drive the clamping frames on both sides to move after rotation, so that they can be brought together or dispersed.

[0016] Preferably, a support frame is fixedly connected to one side of the inspection platform, a motor is fixedly connected to one side of the support frame, and a second lead screw is rotatably connected to one side of the support frame.

[0017] As a further description of the above technical solution: the support frame can be used to install the motor and the No. 2 lead screw.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 6As shown, one embodiment of this utility model includes a maintenance platform 1. Two fixed frames 3 are fixedly connected to the upper ends of the maintenance platform 1. Two clamping frames 12 are slidably connected to the upper ends of the fixed frames 3. Mounting frames 14 are vertically fixedly connected to the upper ends of both clamping frames 12. Clamping plates 13 are slidably connected inside the two mounting frames 14. A lead screw 19 is rotatably connected to the middle of each of the two mounting frames 14. The outer surfaces of the two lead screws 19 are threadedly connected to the middle of the two clamping plates 13. An adjustment mechanism is provided inside each of the two clamping frames 12. The adjustment mechanism includes a synchronous pulley 21. A first bevel gear 17 is fixedly connected to one side, and a second bevel gear 18 is fixedly connected to the lower end of a first lead screw 19. The outer surface of the second bevel gear 18 meshes with the outer surface of the first bevel gear 17. A second synchronous pulley 22 is rotatably connected to the lower part of the clamping frame 12. A transmission belt 20 is connected between the first synchronous pulley 21 and the second synchronous pulley 22. A hexagonal prism 23 is rotatably connected inside the fixing frame 3. The outer surface of the hexagonal prism 23 is slidably connected to the middle part of the second synchronous pulley 22. A first knob 15 is rotatably connected to one side of the fixing frame 3. One end of the first knob 15 passes through one end of the fixing frame 3 and is fixedly connected to one end of the hexagonal prism 23.

[0034] In this embodiment, when adjusting the clamping mechanism to clamp the blade, the hexagonal prism 23 can be rotated by turning the first knob 15. Subsequently, the hexagonal prism 23 will drive the second synchronous wheel 22 below the clamping frame 12 on both sides to rotate. At this time, the second synchronous wheel 22 will drive the first synchronous wheel 21 above to rotate through the transmission belt 20, which in turn drives the first bevel gear 17 fixedly connected to it to rotate. At this time, the second bevel gear 18 meshing with it can rotate and drive the first lead screw 19 to rotate. The rotating first lead screw 19 can drive the clamping plate 13 to slide on the mounting frame 14 for clamping the blade. In this way, when the device controls the clamping plate 13 to perform clamping work, it only needs to turn the first knob 15 to drive the clamping plates 13 on both sides to move simultaneously for clamping the blade. This method can effectively reduce repetitive labor during blade maintenance and improve the efficiency of wind turbine blade maintenance.

[0035] Example 2, as Figures 1 to 3As shown, a bidirectional lead screw 11 is rotatably connected to one side of the upper end of the fixed frame 3. The outer surface of the bidirectional lead screw 11 is threadedly connected to one side of the clamping frame 12. A second knob 16 is fixedly connected to one end of the bidirectional lead screw 11. A support frame 9 is vertically fixedly connected to the rear side of the maintenance platform 1. A motor 8 is fixedly connected to one side of the support frame 9. A second lead screw 6 is rotatably connected to one side of the support frame 9. The output end of the motor 8 is fixedly connected to one end of the second lead screw 6. A sliding block 7 is slidably connected to one side of the support frame 9. The middle part of the sliding block 7 is threadedly connected to the outer surface of the second lead screw 6. A lighting mechanism 4 is rotatably connected to one side of the sliding block 7. Support legs 2 are fixedly connected to all four sides of the maintenance platform 1.

[0036] In this embodiment, when adjusting the spacing between the two clamping frames 12, the bidirectional lead screw 11 can be rotated by turning the second knob 16. The rotating bidirectional lead screw 11 will cause the two clamping frames 12 to move on the fixed frame 3. When the fixed frame 3 moves, the second synchronous wheel 22 installed below the fixed frame 3 can slide on the hexagonal prism 23. At this time, it can be achieved that adjusting the position of the two clamping frames 12 will not affect the smooth operation of the clamping plates 13. By setting the lighting mechanism 4 above the maintenance table 1, the lighting can be used according to the actual situation during maintenance work. The height of the lighting mechanism 4 can be adjusted according to the needs. This can be done by starting the motor 8, which drives the second lead screw 6 to rotate. The rotating lead screw 6 drives the sliding block 7 to move on the support frame 9, and after moving, it drives the lighting mechanism 4 installed on one side to rise and fall. At this time, the height of the lighting mechanism 4 can be adjusted. In this way, the height of the lighting mechanism 4 and the position of the clamping frame 12 can be adjusted in a timely manner according to the actual usage needs, making the device more adaptable to different usage needs and improving the applicability of the device.

[0037] Working Principle: When using the device, the wind turbine blades to be inspected can be placed on the inspection platform 1. The blades can then be clamped by adjusting the clamping plate 13. While adjusting the clamping mechanism, rotating the first knob 15 rotates the hexagonal prism 23. The hexagonal prism 23 then rotates the second synchronous pulleys 22 below the clamping frames 12 on both sides. These second synchronous pulleys 22, via the transmission belt 20, rotate the first synchronous pulley 21 above, which in turn drives the first bevel gear 17, which is fixedly connected to it, to rotate. The meshing second bevel gear 18 then rotates, driving the first lead screw 19 to rotate. The rotating lead screw 19 drives the clamping plate 13 to slide on the mounting frame 14, thus clamping the blades. This method allows the device to control the clamping plate 13 by simply rotating the first knob 15. 5 can drive the clamping plates 13 on both sides to move simultaneously for clamping the blades. This method can effectively reduce repetitive labor during blade maintenance and improve the efficiency of wind turbine blade maintenance. By setting a lighting mechanism 4 above the maintenance platform 1, the height of the lighting mechanism 4 can be adjusted according to actual usage needs during maintenance. When adjusting, the motor 8 can be started, which can drive the second lead screw 6 to rotate. The rotating second lead screw 6 can drive the sliding block 7 to move on the support frame 9, and after moving, it can drive the lighting mechanism 4 installed on one side to rise and fall. At this time, the height of the lighting mechanism 4 can be adjusted. Through this method, the height of the lighting mechanism 4 and the position of the clamping frame 12 can be adjusted in time according to actual usage needs, making the device more adaptable to different usage needs and improving the applicability of the device.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
