Description

Technical Field

[0002] Wind turbine flange is a structural part that connects the tower sections or the tower and the hub, the hub and the blades, and is usually connected by bolts. Wind turbine flange is also called wind tower flange. Wind turbine flange is simply the flange of wind turbine generator set. The production process of wind turbine flange is raw material testing, cutting, sawing, heating, ring rolling, heat treatment, rough processing and fine processing; Wind turbine flanges generally have a relatively large diameter. Manual measurement has the problems of inaccurate measurement, long measurement time, and cumbersome measurement operation. In addition, the placement of the wind turbine flange during device measurement is likely to affect the detection data. The skewed and misaligned placement of the wind turbine flange will cause large errors in the measured data. In order to improve the measurement accuracy of the distance measuring device, the distance measuring device will often be made to fit the inner and outer walls of the wind turbine flange more closely.

[0019] The support seat 1 includes an inner ring and an outer ring arranged coaxially, and both the inner ring and the outer ring are vertically arranged cylindrical structures with open ends, and the inner ring is sleeved on the inner side of the outer ring. A plurality of support connecting plates 2 arranged in a circular array are fixedly arranged between the inner ring and the outer ring, and the support connecting plates 2 are arranged along the radial direction of the inner ring and the outer ring, and the inner ring and the outer ring are fixedly connected through the support connecting plates 2.

[0020] The rotating mechanism 3 includes a fixed plate 8, a first motor 7, a driving gear 9, a driven gear ring 12, and a bottom plate. A bottom plate is fixedly arranged at the lower end of the lifting column 4. The bottom plate is a horizontally arranged circular plate-shaped structure. The bottom plate is rotatably arranged inside the inner ring of the support seat 1, and a driven gear ring 12 is fixedly arranged on the lower end surface of the bottom plate.

The driving gear 9 is located on the inner side of the driven gear ring 12, and the driving gear 9 is meshed with the driven gear ring 12.

[0021] When the first motor 7 is running, it drives the driving gear 9 to rotate. Since the driving gear 9 is meshed with the driven gear ring 12, the driven gear ring 12 is driven to rotate. The driven gear ring 12 drives the bottom plate to rotate, and the bottom plate drives the lifting column 4 to rotate horizontally.

[0022] The lifting mechanism includes a first linear motor slide rail 13 and a first linear motor slider 14. A vertical first linear slide rail is fixedly arranged on the front vertical surface of the lifting column 4, and the first linear motor slider 14 is slidably arranged inside the first linear motor slide rail 13. The lifting seat is fixedly arranged on the first linear motor slider 14.

[0023] A second motor 15 is fixedly arranged on the lifting seat, and a limit swivel block 16 is fixedly arranged on the output shaft of the second motor 15, and the limit swivel block 16 is a cubic structure. A fixing groove is arranged at one end of the sliding transfer rod 10, and the limit swivel block 16 is fixedly engaged in the fixing groove of the sliding transfer rod 10. When the second motor 15 rotates, the limit swivel block 16 is driven to rotate, and since the limit swivel block 16 is fixedly connected to the sliding transfer rod 10, the sliding transfer rod 10 is driven to rotate. When the measuring device is in a working state as a whole, the sliding transfer rod 10 is in a horizontal state; when the measuring device is not in a working state, the sliding transfer rod 10 is in a vertical state, and the sliding transfer rod 10 and the lifting column 4 are approximately in a vertical line, so that the wind power flange can pass through the sliding transfer rod 10 and the lifting column 4 and be placed on the upper end of the support seat 1 or detached from the support seat 1.

[0024] The first sliding assembly includes a third motor 17 and a transmission screw 18. A first sliding groove is provided on the sliding transfer rod 10, and the first sliding groove is provided along the length direction of the sliding transfer rod 10. The transmission screw 18 is rotatably provided inside the first sliding groove, and the third motor 17 is fixedly provided at one end of the sliding transfer rod 10, and the output shaft of the third motor 17 is fixedly connected to one end of the transmission screw 18. The transmission screw 18 is driven to rotate inside the sliding transfer rod 10 by the third motor 17.

[0025] The extension direction of the sliding sleeve 21 is parallel to the extension direction of the sliding transfer rod 10. A first sliding block 23 and a second sliding block 24 are fixedly arranged on the outer side of the sliding sleeve 21, and the first sliding block 23 and the second sliding block 24 are arranged along the extension direction of the sliding sleeve 21. The first sliding block 23 and the second sliding block 24 are both inserted into the first sliding groove of the sliding transfer rod 10, and the outer walls of the first sliding block 23 and the second sliding block 24 are in sliding contact with the inner wall of the first sliding groove, and the first sliding block 23 and the second sliding block 24 are both screwed to the transmission screw 18.

[0026] When the third motor 17 drives the transmission screw 18 to rotate, the third screw drives the first sliding block 23 and the second sliding block 24 to slide along the transmission screw 18 , and the first sliding block 23 and the second sliding block 24 drive the sliding sleeve 21 to slide on the sliding rotating rod 10 .

[0027] The second sliding assembly also includes a fourth motor 25, a threaded rotating rod 28, a threaded sleeve block 29, and an abutting connecting block 26. The sliding sleeve 21 and the telescopic sleeve 22 are both linear rod structures, and one end of the telescopic sleeve 22 is slidably inserted into the end of the sliding sleeve 21 away from the sliding rotating rod 10. A second sliding groove is provided inside the sliding sleeve 21, and the second sliding groove is a square hole-shaped structure. A threaded sleeve block 29 with a cubic structure is slidably provided inside the second sliding groove, and the outer wall of the threaded sleeve block 29 maintains sliding contact with the inner wall of the second sliding groove. A threaded rotating rod 28 is rotatably provided inside the second sliding groove, and the threaded rotating rod 28 is screwed to the threaded sleeve block 29. A fourth motor 25 is fixedly provided at one end of the sliding sleeve 21 close to the sliding rotating rod 10, and the output shaft of the fourth motor 25 is fixedly connected to one end of the threaded rotating rod 28.

The abutting connecting block 26 is fixedly connected to one end of the telescopic sleeve rod 22 extending into the inner side of the sliding sleeve rod 21 .

[0028] When the fourth motor 25 rotates, it drives the threaded rotating rod 28 to rotate. Since the threaded rotating rod 28 is threadedly connected to the threaded sleeve block 29, the threaded sleeve block 29 is driven to slide inside the second sliding groove of the sliding sleeve rod 21. When the sliding sleeve block slides, it drives the telescopic sleeve rod 22 to slide inside the sliding sleeve rod 21 through the pressure sensor 30, the buffer detection spring 31, and the abutment connecting block 26, thereby realizing the sliding of the telescopic sleeve rod 22. When the telescopic sleeve rod 22 slides, the buffer detection spring 31 is compressed, and the compression force of the buffer detection spring 31 is applied to the pressure sensor 30. The external force on the telescopic sleeve rod 22 can be detected by the reading of the pressure sensor 30.

[0029] The model of the pressure sensor 30 is YPR-8. The piezoresistive sensor uses the piezoresistive effect. When the material is subjected to mechanical stress, its resistance value will change, so the pressure can be determined by measuring the change in resistance value. The rotation of the threaded rotating rod 28 can adjust the extension of the threaded sleeve block 29 to control the sliding extension of the telescopic sleeve rod 22. The pressure sensor 30 and the buffer detection spring 31 can protect the device while balancing the centrifugal force of the device rotation through the tension of the buffer detection spring 31. The roundness of the inner and outer diameters of the wind turbine flange can be observed through the detection value fluctuation of the pressure sensor 30, and the detection data of the swing rod detection component can be supplemented, thereby improving the detection accuracy of the device.

[0030] A second linear motor rail 27 is fixedly provided on the lower end surface of the telescopic sleeve 22, and the second linear motor rail 27 is extended along the length direction of the telescopic sleeve 22.

[0036] The present invention provides a method for using a measuring device for detecting the diameter of a wind turbine flange, comprising the following steps: Step 1, first, connect the hydraulic pump to each hydraulic connecting plate 6 on the support seat 1, and then connect the power to each motor of the device; control the sliding rod 10, the sliding sleeve rod 21, and the telescopic sleeve rod 22 to be in a horizontal state, control the first swing rod 19 and the detection rotating block 43 to be in a vertical state, and detect the second distance detector 46 on the rotating block 43 vertically downward toward the supporting surface at the upper end of the support seat 1, and drive the lifting column 4 to rotate through the first motor 7, and the lifting column 4 drives the sliding detection mechanism to rotate as a whole, thereby driving the first swing rod 19 to rotate horizontally, and the second distance detector 46 on the first swing rod 19 detects the flatness of the supporting surface at the upper end of the support seat 1.

[0037] Step 2, start the first linear motor slider 14 and the second motor 15, lower the lifting seat through the operation of the first linear motor slider 14, and drive the sliding rod 10 to rotate through the second motor 15, so that the sliding rod 10 remains vertical, so that the sliding sleeve 21 and the telescopic sleeve 22 both remain vertical; then start the fifth motor 39 and the sixth motor 42, so that the first swing arm 19 and the second swing arm 20 rotate and fit tightly to one side of the telescopic sleeve 22, so that the sliding rod 10, the sliding sleeve 21, the telescopic sleeve 22, the first swing arm 19, and the second swing arm 20 all rotate to a vertical state, and the sliding detection mechanism as a whole is in a vertical storage state, which is convenient for lifting the large wind turbine flange and placing it on the support seat 1, preventing the large wind turbine flange from colliding with the components of the measuring device during the lifting process.

[0038] Step three, then slowly lower the large wind turbine flange through the lifting equipment. When the large wind turbine flange is about to approach the supporting surface at the upper end of the support seat 1, start the hydraulic pump to lift up the supporting base block 33 in the hydraulic chamber 35 closest to the inner ring on each hydraulic connecting plate 6, and open the solenoid valve tube 36 in the hydraulic chamber 35, so that each supporting base block 33 rises from the inside to the outside in turn, thereby pushing the suspended large wind turbine flange to better complete the centering placement; the setting of the detection airbag 34 can better protect the edge of the large wind turbine flange and prevent damage by knocking. At the same time, the state of the large wind turbine flange centering is judged by detecting the compression amount of the airbag 34, so that the large wind turbine flange is smoothly lowered and placed, thereby reducing the detection error of subsequent devices.

[0039] Step four, then start the first linear motor slider 14 and the second motor 15 again, so that the sliding rod 10 rises and rotates to a horizontal state, and then start the third motor 17 to rotate the transmission screw 18, thereby pushing the combined extension rod 11 to slide out from the end of the sliding rod 10 away from the lifting column 4, and then start the second linear motor slider 37 and the third linear motor slider 41 on the second linear motor slide rail 27, so that the first swing arm 19 and the second swing arm 20 are located above the inner and outer sides of the wind turbine flange; then lower the sliding rod 10, so that the first swing arm 19 and the second swing arm 20 are located on the inner and outer sides of the wind turbine flange.

[0040] Step five, control the abutment roller 38 on the first swing arm 19 to roll in contact with the outer cylindrical surface of the wind turbine flange through the second linear motor slider 37, and control the abutment roller 38 on the second swing arm 20 to disengage from the inner cylindrical surface of the wind turbine flange through the third linear motor slider 41.

[0041] Step six, start the second distance detector 46, and start the first motor 7 to drive the lifting column 4 to rotate. When the lifting column 4 rotates, it drives the entire slip detection mechanism to rotate horizontally. At this time, the detection rotating block 43 rotates to a horizontal state, and the second distance detector 46 on the detection rotating block 43 faces the outer cylindrical surface of the wind turbine flange. When the first swing arm 19 rotates horizontally with the lifting column 4, the abutting roller 38 on the first swing arm 19 rolls on the outer cylindrical surface of the wind turbine flange, and the distance between the outer cylindrical surface of the wind turbine flange and the first swing arm 19 is detected by the second distance detector 46. When the outer diameter roundness of the wind turbine flange is uneven, the telescopic sleeve 22 will jump under the drive of the first swing arm 19 and the second swing arm 20, so that the buffer detection spring 31 jumps, and the reading on the pressure sensor 30 also jumps, so as to detect the roundness of the outer cylindrical surface of the wind turbine flange.

[0042] Step seven, control the abutment roller 38 on the first swing arm 19 to disengage from the outer cylindrical surface of the wind turbine flange through the second linear motor slider 37, and control the abutment roller 38 on the second swing arm 20 to roll in contact with the inner cylindrical surface of the wind turbine flange through the third linear motor slider 41.

[0043] Step eight, start the second distance detector 46, and start the first motor 7 to drive the lifting column 4 to rotate. When the lifting column 4 rotates, it drives the entire slip detection mechanism to rotate horizontally. At this time, the first distance detector 40 on the second swing rod 20 faces the inner cylindrical surface of the wind turbine flange; when the second swing rod 20 rotates horizontally with the lifting column 4, the abutting roller 38 on the second swing rod 20 rolls on the inner cylindrical surface of the wind turbine flange, and the distance between the inner cylindrical surface of the wind turbine flange and the second swing rod 20 is detected by the first distance detector 40. When the inner diameter roundness of the wind turbine flange is uneven, the telescopic sleeve 22 will jump under the drive of the first swing rod 19 and the second swing rod 20, so that the buffer detection spring 31 jumps, and the reading on the pressure sensor 30 also jumps, so as to detect the roundness of the inner cylindrical surface of the wind turbine flange. The pressure sensor 30 and the buffer detection spring 31 enable the device to play a protective role. At the same time, the centrifugal force of the overall rotation of the slip detection mechanism is balanced through the tension of the buffer detection spring 31. The roundness of the inner and outer diameters of the wind turbine flange can be observed through the detection value fluctuations of the pressure sensor 30, and the detection data of the rocker detection component can be supplemented, thereby improving the detection accuracy of the device.

[0044] Step nine, when the first swing arm 19 moves to the upper end of the wind turbine flange, the detection rotating block 43 is rotated to a vertical state, and the second distance detector 46 on the detection rotating block 43 is vertically downward toward the upper end surface of the wind turbine flange. When the lifting column 4 drives the first swing arm 19 to rotate, the second distance detector 46 on the first swing arm 19 detects the upper end surface of the wind turbine flange, thereby detecting the flatness of the upper end surface of the wind turbine flange.
