Description

Technical Field

[0001] The utility model belongs to the technical field of punching equipment, and in particular relates to a wind turbine blade punching device. Background Art

[0002] Wind power generation is the process of converting the kinetic energy of wind into mechanical energy, and then converting mechanical energy into electrical energy. The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then increase the speed of rotation through a speed increaser to drive the generator to generate electricity. According to current windmill technology, power generation can begin at a breeze speed of about three meters per second. Wind power generation is becoming a trend in the world because wind power generation does not require the use of fuel and does not produce radiation or air pollution. The device required for wind power generation is called a wind turbine. This type of wind turbine can be roughly divided into three parts: the wind rotor, the generator and the tower. The wind rotor is also called a wind turbine blade. The wind turbine blade is connected to the motor rotor through a connection hole drilled at the root.

[0004] This application fixes the wind turbine blades through four circumferentially arranged threaded columns, but the wind turbine blades are set horizontally when being fixed. Due to the weight of the other end, they are prone to tilting, affecting the drilling effect. At the same time, during long-term use, the vibration of the drilling can easily cause the threaded columns to loosen, resulting in unstable fixation and tilting of the blades, which needs to be improved.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the utility model clearer and more understandable, the technical solution of the utility model will be further described in detail below with reference to the accompanying drawings.

[0018] like Figure 1 , Figure 2 , Figure 3 As shown, a wind turbine blade punching device provided by the utility model includes a base 1, a punching unit 2 and an anti-tilt positioning unit 3, the punching unit 2 and the anti-tilt positioning unit 3 are both arranged on the base 1, the anti-tilt positioning unit 3 includes a column 14, a second hydraulic extruder 15 and a support seat 16, the column 14 is fixedly installed at the center of the base 1, a plurality of second hydraulic extruders 15 are equidistantly installed in a circle on the side of the column 14, the support seats 16 are fixedly connected to the telescopic ends of the second hydraulic extruders 15 one by one, and the punching unit 2 is used to punch holes in the wind turbine blades.

[0019] When drilling holes, the wind turbine blade is set in a vertical shape and placed on the support seat 16, and then the second hydraulic squeezer 15 is started to drive the support seat 16 to move outward, so that the wind turbine blade can be fixed, and then the wind turbine blade can be drilled by the drilling unit 2. Since the wind turbine blade is set vertically, the dead weight of the other end will not cause the wind turbine blade to tilt, making the drilling more accurate.

[0020] The support seat 16 includes an arc panel 161 and an arc flange 162 . The arc panel 161 is fixedly connected to the telescopic end of the second hydraulic extruder 15 , and the arc flange 162 is integrally formed at the bottom edge of the arc panel 161 .

[0021] The curved panel 161 can better fit the inner wall of the wind turbine blade. When fixing the wind turbine blade, there are more stress points and the wind turbine blade is more stable. The curved flange 162 is used to support the wind turbine blade. When fixed, the end face of the wind turbine blade can fit with the upper surface of the curved flange 162, thereby supporting the wind turbine blade as a whole.

[0022] The punching unit 2 includes a punching component and a rotation positioning mechanism, the rotation positioning mechanism includes a support column 4, a rotating seat 5, a rotating ring 6 and a driving component, the support column 4 is fixedly connected to the base 1 and is arranged in a circular shape around the column 14, the rotating seat 5 is fixedly connected to the top of the support column 4 in a circular ring shape, the rotating ring 6 is movably embedded in the rotating seat 5, the driving component is used to drive the rotating ring 6 to rotate along the circumferential direction of the rotating seat 5, and the punching component is fixedly connected to the rotating ring 6.

[0023] When the driving assembly drives the rotating ring 6 to move, the rotating ring 6 can rotate along the circumferential direction of the rotating seat 5. Since the column 14 is arranged at the center of the base 1, the rotating ring 6 is arranged in a circle with the column as the center, so it can drive the punching assembly to move in a circle around the wind turbine blade, thereby realizing precise punching in multiple positions.

[0024] The punching assembly includes a hydraulic telescopic column 11, a first hydraulic squeezer 12 and a drill 13. The hydraulic telescopic column 11 is fixedly connected to the rotating ring 6, the first hydraulic squeezer 12 is fixedly connected to the telescopic end of the hydraulic telescopic column 11, and the drill 13 is fixedly connected to the movable end of the first hydraulic squeezer 12.

[0025] The hydraulic telescopic column 11 can drive the first hydraulic squeezer 12 to perform telescopic movement, thereby making the drill 13 close to the wind turbine blade in the horizontal direction. The hydraulic telescopic column 12 can drive the drill 13 to perform lifting movement in the vertical direction, so that it is close to the wind turbine blade for drilling.

[0026] The driving assembly includes a fixed seat 7, a motor 8 and a gear 9. The fixed seat 7 is fixedly connected to the support column 4, the motor 8 is fixedly installed on the fixed seat 7, and the gear 9 is installed on the output shaft of the motor 8 and passes through the rotating seat 5 to engage with the rotating ring 6.

[0027] After the motor 8 is started, it can directly drive the gear 9 to rotate. Since the gear 9 passes through the rotating seat 5 and meshes with the rotating ring 6, the rotating ring 6 can be driven to move when the gear 9 rotates, thereby causing the punching assembly to move synchronously.

[0028] In summary, the working process of the utility model is as follows: first, visually measure the size of the root of the wind turbine blade, and then start the second hydraulic squeezer 15 to open the support seat 16, and then put the wind turbine blade on the support seat 16 in a vertical state, so that the end of the wind turbine blade contacts the upper surface of the arc flange 162, and then start the second hydraulic squeezer 15 again to make the support seat 16 continue to open outward to fix the wind turbine blade, and then start the hydraulic telescopic column 11 and the first hydraulic squeezer 12 to drive the puncher 13 to approach the wind turbine blade for drilling. After completion, the hydraulic telescopic column 11 and the hydraulic squeezer 12 drive the puncher 13 back to its original position, and then start the motor 8 to drive the rotating ring 6 to rotate, so that the puncher 13 moves to the next predetermined position for drilling, and then repeat the operation until the drilling is completed.
