Description

Technical Field

[0001] The present invention belongs to the technical field of wind power flange measuring tools, and particularly relates to a measuring device for detecting the diameter of a wind power flange. Background Art

[0002] A wind power flange is a structural member that connects each section of a tower barrel or the tower barrel and a hub, and between the hub and the blades. It is usually connected by bolts. A wind power flange is also called a wind tower flange. Briefly speaking, a wind power flange is a flange of a wind turbine generator. The manufacturing process of a wind power flange is raw material detection, cutting, sawing, heating, ring rolling forming, heat treatment, rough machining and finish machining;

[0003] Wind power flanges generally have a relatively large diameter. Manual measurement has problems such as inaccurate measurement, long measurement time, and cumbersome measurement operations. Moreover, the placement of the wind power flange during device measurement is likely to affect the detection data. The placement skew and misalignment of the wind power flange will cause large errors in the measured data. And in order to improve the measurement accuracy of the distance measuring device, the distance measuring device is often made to fit more closely to the inner and outer side walls of the wind power flange. However, due to the change in the roundness of the inner and outer walls of the wind power flange, the detection device will experience slight fluctuations, resulting in a reduction in the detection accuracy of the existing device.

[0035] As Figure 1As shown in FIGS. 1 - 14, the present invention provides a measuring device for detecting the diameter of a wind power flange, including a support base 1. At the center of the support base 1, a vertical lifting column 4 is rotatably arranged through a rotating mechanism 3. An elevating seat is arranged on the lifting column 4 through a lifting mechanism, and a sliding detection mechanism is arranged on the elevating seat. The sliding detection mechanism includes a sliding rotating rod 10, a combined extension rod 11, and a swing rod detection component. The sliding rotating rod 10 is rotatably arranged on the elevating seat. The combined extension rod 11 includes a sliding sleeve rod 21 and a telescopic sleeve rod 22. The sliding sleeve rod 21 is slidably arranged on the sliding rotating rod 10 through a first sliding component, and the telescopic sleeve rod 22 is slidably inserted into the interior of the sliding sleeve rod 21 through a second sliding component. The second sliding component includes a pressure sensor 30 and a buffer detection spring 31. A swing rod detection component is arranged on the telescopic sleeve rod 22. The swing rod detection component includes a first swing rod 19 and a second swing rod 20. Both the first swing rod 19 and the second swing rod 20 are slidably arranged on the telescopic sleeve rod 22, and distance detectors are arranged on both the first swing rod 19 and the second swing rod 20.

[0036] The support base 1 includes an inner ring and an outer ring arranged coaxially. Both the inner ring and the outer ring are cylindrical structures with open upper and lower ends arranged vertically. The inner ring is sleeved inside 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. 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. A support pad 5 is fixedly arranged on the lower end surface of the outer ring of the support base 1.

[0037] 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 base 1, and a driven gear ring 12 is fixedly arranged on the lower end surface of the bottom plate. A horizontal fixed plate 8 is fixedly designed inside the inner ring of the support base 1. A first motor 7 is fixedly arranged on the fixed plate 8. The output shaft of the first motor 7 is vertically upward, and a driving gear 9 is fixedly arranged on the output shaft of the first motor 7. The driving gear 9 is located inside the driven gear ring 12, and the driving gear 9 meshes with the driven gear ring 12.

[0038] When the first motor 7 operates, it drives the driving gear 9 to rotate. Since the driving gear 9 meshes 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.

[0039] The lifting mechanism includes a first linear motor slide rail 13 and a first linear motor slide block 14. A vertical first linear slide rail is fixedly arranged on the front vertical surface of the lifting column 4. The first linear motor slide block 14 is slidably arranged inside the first linear motor slide rail 13. The lifting seat is fixedly arranged on the first linear motor slide block 14. Through the mutual cooperation of the first linear motor slide rail 13 and the first linear motor slide block 14, the lifting seat is driven to lift on the lifting column 4.

[0040] A second motor 15 is fixedly arranged on the lifting seat. A limiting rotating block 16 is fixedly arranged on the output shaft of the second motor 15. The limiting rotating block 16 is of a cube structure. A fixing groove is arranged at one end of the sliding rotating rod 10. The limiting rotating block 16 is fixedly clamped inside the fixing groove of the sliding rotating rod 10. When the second motor 15 rotates, it drives the limiting rotating block 16 to rotate. Since the limiting rotating block 16 is fixedly connected to the sliding rotating rod 10, the sliding rotating rod 10 is driven to rotate. When the whole measuring device is in the working state, the sliding rotating rod 10 is in the horizontal state; when the measuring device is in the non-working state, the sliding rotating rod 10 is in the vertical state, and the sliding rotating rod 10 and the lifting column 4 are approximately on the same vertical line, so that the wind power flange can pass through the sliding rotating rod 10 and the lifting column 4 and be placed on the upper end of the support seat 1 or be detached from the support seat 1.

[0041] The first sliding assembly includes a third motor 17 and a transmission lead screw 18. A first sliding groove is arranged on the sliding rotating rod 10. The first sliding groove is arranged along the length direction of the sliding rotating rod 10. The transmission lead screw 18 is rotatably arranged inside the first sliding groove. A third motor 17 is fixedly arranged at one end of the sliding rotating rod 10. The output shaft of the third motor 17 is fixedly connected to one end of the transmission lead screw 18. The third motor 17 drives the transmission lead screw 18 to rotate inside the sliding rotating rod 10.

[0042] The extending direction of the sliding sleeve rod 21 is parallel to the extending direction of the sliding rotating rod 10. A first sliding block 23 and a second sliding block 24 are fixedly arranged on the outer side surface of the sliding sleeve rod 21. The first sliding block 23 and the second sliding block 24 are arranged along the extending direction of the sliding sleeve rod 21. Both the first sliding block 23 and the second sliding block 24 are inserted into the first sliding groove of the sliding rotating rod 10. 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 both the first sliding block 23 and the second sliding block 24 are screwed to the transmission lead screw 18.

[0043] When the third motor 17 drives the transmission lead screw 18 to rotate, the third lead screw drives the first sliding block 23 and the second sliding block 24 to slide along the transmission lead screw 18. The first sliding block 23 and the second sliding block 24 drive the sliding sleeve rod 21 to slide on the sliding rotating rod 10.

[0044] The second sliding component further includes a fourth motor 25, a threaded rotating rod 28, a threaded sleeve block 29, and a connecting block 26. Both the sliding sleeve rod 21 and the telescopic sleeve rod 22 are linear rod-shaped structures. One end of the telescopic sleeve rod 22 is slidably inserted into the inner part of the end of the sliding sleeve rod 21 away from the sliding rotating rod 10. A second sliding groove is provided inside the sliding sleeve rod 21. The second sliding groove is a square hole-shaped structure. A threaded sleeve block 29 with a cube structure is slidably arranged inside the second sliding groove. 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 arranged inside the second sliding groove. The threaded rotating rod 28 is threadedly connected to the threaded sleeve block 29. A fourth motor 25 is fixedly arranged at the end of the sliding sleeve rod 21 close to the sliding rotating rod 10. The output shaft of the fourth motor 25 is fixedly connected to one end of the threaded rotating rod 28. A pressure sensor 30, a buffer detection spring 31, and a connecting block 26 are sequentially fixedly arranged at the end of the threaded sleeve block 29 close to the telescopic sleeve rod 22. The connecting block 26 is fixedly connected to the end of the telescopic sleeve rod 22 extending into the inner side of the sliding sleeve rod 21.

[0045] 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, it drives the threaded sleeve block 29 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 connecting block 26, thus realizing the sliding of the telescopic sleeve rod 22. When the telescopic sleeve rod 22 slides, the buffer detection spring 31 is compressed. The compression force of the buffer detection spring 31 is applied to the pressure sensor 30. The external force received by the telescopic sleeve rod 22 can be detected through the reading of the pressure sensor 30.

[0046] The model of the pressure sensor 30 is YPR-8. The piezoresistive sensor utilizes the piezoresistive effect. When the material is subjected to mechanical stress, its resistance value will change, so as to determine the magnitude of the pressure by measuring the change in the resistance value. The rotation of the threaded rotating rod 28 can adjust the extension amount of the threaded sleeve block 29, thereby controlling the sliding extension amount of the telescopic sleeve rod 22. While the device plays a protective role through the action of the pressure sensor 30 and the buffer detection spring 31, the centrifugal force of the rotating device is balanced by the pulling force of the buffer detection spring 31, and the roundness of the inner and outer diameters of the wind power flange can be observed through the fluctuation of the detection value of the pressure sensor 30, supplementing the detection data of the swing rod detection component, thereby improving the detection accuracy of the device.

[0047] A second linear motor slide rail 27 is fixedly arranged on the lower end surface of the telescopic sleeve rod 22, and the second linear motor slide rail 27 extends along the length direction of the telescopic sleeve rod 22. A second linear motor slider 37 and a third linear motor slider 41 are slidably arranged inside the second linear motor slide rail 27. A first hinge seat is fixedly arranged at the lower end of the second linear motor slider 37, and a second hinge seat is fixedly arranged at the lower end of the third linear motor slider 41. The first hinge seat is driven to slide by the mutual cooperation of the second linear motor slider 37 and the second linear motor slide rail 27, and the second hinge seat is driven to slide by the mutual cooperation of the third linear motor slider 41 and the second linear motor slide rail 27.

A fifth motor 39 is fixedly arranged on the second hinge seat, and the output shaft of the fifth motor 39 is fixedly connected to the rotating shaft of the second swing rod 20. The second swing rod 20 is driven to rotate inside the second hinge seat by the fifth motor 39. A sixth motor 42 is fixedly arranged on the first hinge seat, and the output shaft of the sixth motor 42 is fixedly connected to the rotating shaft of the first swing rod 19. The first swing rod 19 is driven to rotate inside the first hinge seat by the sixth motor 42.

[0049] On the lower ends of the end faces on the sides where the first swing rod 19 and the second swing rod 20 are close to each other, two symmetrically arranged abutting rollers 38 are rotatably provided respectively. On the lower end of the end face of the second swing rod 20 on the side close to the first swing rod 19, a first distance detector 40 is fixedly provided. At the lower end of the first swing rod 19, a rotating groove is provided, and a detection rotating block 43 is rotatably provided inside the rotating groove. On the inner wall of the rotating groove, a seventh motor 44 is fixedly provided, and the output shaft of the seventh motor 44 is fixedly connected to the rotating shaft of the detection rotating block 43. The detection rotating block 43 is driven by the seventh motor 44 to rotate inside the rotating groove. On the lower end face of the detection rotating block 43, a second distance detector 46 is fixedly provided. On the front side face of the detection rotating block 43, an ∩-shaped third hinge seat is fixedly provided, and a flat plate level detector 45 is rotatably provided inside the third hinge seat through a connecting rotating shaft 47. A torsion spring 48 is provided between the connecting rotating shaft 47 and the third hinge seat. When the detection rotating block 43 rotates to the horizontal state, the flat plate level detector 45 is squeezed to fit against the lower end face of the first swing rod 19. At this time, the torsion spring 48 is in a compressed state, and at this time, the flat plate level detector 45 is in a horizontal state. Through the horizontal flat plate level detector 45, it can be detected whether the first swing rod 19 is in a vertical state. When the detection rotating block 43 rotates to the vertical state, the flat plate level detector 45 rotates 90° under the action of the resilience of the torsion spring 48. At this time, the flat plate level detector 45 is perpendicular to the front side face of the detection rotating block 43, and at this time, the flat plate level detector 45 is in a horizontal state. Through the horizontal flat plate level detector 45, it can be detected whether the first swing rod 19 is in a vertical state.

[0050] Both the first distance detector 40 and the second distance detector 46 are infrared distance detectors, with the model number TCW1, and adopt the reflection measurement method.

The hydraulically connected plates 6 are arranged along the radial direction of the inner ring, and the plurality of hydraulically connected plates 6 and the plurality of support connecting plates 2 are arranged alternately. On the upper end face of each hydraulically connected plate 6, a plurality of equally spaced hydraulic chambers 35 are provided, and the plurality of hydraulic chambers 35 are arranged along the radial direction of the inner ring. Adjacent hydraulic chambers 35 are connected by solenoid valve pipes 36. The hydraulic chamber 35 closest to the inner ring on each hydraulically connected plate 6 is connected to a hydraulic pump.

[0052] Inside each hydraulic chamber 35, a support base block 33 is slidably provided respectively, and the support base block 33 slides along the vertical direction. The support base block 33 is located in the vertical plane of the radial direction of the inner ring. At the upper end of the support base block 33, an arc-shaped abutting top block 32 is fixedly provided, and the height of the abutting top block 32 gradually decreases along the direction close to the inner ring. On both sides of the abutting top block 32, two symmetrically arranged detection air bags 34 are fixedly provided.

[0053] A method for using a measuring device for detecting the diameter of a wind power flange provided by the present invention comprises the following steps:

[0054] Step 1: First, connect a hydraulic pump to each hydraulic connecting plate 6 on the support base 1, and then connect a power supply to each motor of the device; control the sliding rotating 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, the second distance detector 46 on the detection rotating block 43 is vertically downward towards the support surface at the upper end of the support base 1, drive the lifting column 4 to rotate through the first motor 7, the lifting column 4 drives the entire sliding detection mechanism to rotate, 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 support surface at the upper end of the support base 1.

[0055] 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, drive the sliding rotating rod 10 to rotate through the second motor 15, so that the sliding rotating rod 10 remains vertical, and thus the sliding sleeve rod 21 and the telescopic sleeve rod 22 both remain vertical; then start the fifth motor 39 and the sixth motor 42, so that the first swing rod 19 and the second swing rod 20 rotate and closely adhere to one side of the telescopic sleeve rod 22, so that the sliding rotating rod 10, the sliding sleeve rod 21, the telescopic sleeve rod 22, the first swing rod 19, and the second swing rod 20 all rotate to a vertical state, and the entire sliding detection mechanism is in a vertically retracted state, which is convenient for lifting and placing a large wind power flange on the support base 1, preventing the large wind power flange from colliding with the components of the measuring device during the hoisting process.

[0056] Step 3: Then slowly lower the large wind power flange through a lifting device. When the large wind power flange is about to approach the support surface at the upper end of the support base 1, start the hydraulic pump, so that the support base blocks 33 in the hydraulic chamber 35 closest to the inner ring on each hydraulic connecting plate 6 are jacked up, and open the solenoid valve pipe 36 in the hydraulic chamber 35, so that the support base blocks 33 are sequentially lifted from the inside to the outside, thereby promoting the better centering placement of the hoisted large wind power flange; the setting of the detection airbag 34 can better protect the edge of the large wind power flange, prevent it from being chipped and damaged, and at the same time judge the state of the large wind power flange's centering completion through the compression amount of the detection airbag 34, so as to smoothly lower and place the large wind power flange, thereby reducing the detection error of the subsequent device.

[0057] Step 4: Subsequently, start the first linear motor slider 14 and the second motor 15 again, so that the sliding rotating rod 10 rises and rotates to a horizontal state. Then start the third motor 17, so that the transmission lead screw 18 rotates, thereby pushing the combined extension rod 11 to slide out from the end of the sliding rotating rod 10 away from the lifting column 4. 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 rod 19 and the second swing rod 20 are located above the inner and outer sides of the wind power flange. Then lower the sliding rotating rod 10, so that the first swing rod 19 and the second swing rod 20 are located on the inner and outer sides of the wind power flange.

[0058] Step 5: Control the contact roller 38 on the first swing rod 19 to rollingly contact the outer cylindrical surface of the wind power flange through the second linear motor slider 37, and control the contact roller 38 on the second swing rod 20 to disengage from the inner cylindrical surface of the wind power flange through the third linear motor slider 41.

[0059] Step 6: 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 sliding 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 power flange. When the first swing rod 19 rotates horizontally with the lifting column 4, the contact roller 38 on the first swing rod 19 rolls on the outer cylindrical surface of the wind power flange, and the distance between the outer cylindrical surface of the wind power flange and the first swing rod 19 is detected through the second distance detector 46. When the outer diameter roundness of the wind power flange is uneven, the telescopic sleeve rod 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, thereby detecting the roundness of the outer cylindrical surface of the wind power flange.

[0060] Step 7: Control the contact roller 38 on the first swing rod 19 to disengage from the outer cylindrical surface of the wind power flange through the second linear motor slider 37, and control the contact roller 38 on the second swing rod 20 to rollingly contact the inner cylindrical surface of the wind power flange through the third linear motor slider 41.

[0061] 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 sliding 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 power 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 power flange, and the distance between the inner cylindrical surface of the wind power flange and the second swing rod 20 is detected by the first distance detector 40. When the inner diameter roundness of the wind power flange is uneven, the telescopic sleeve rod 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, thereby detecting the roundness of the inner cylindrical surface of the wind power flange. The functions of the pressure sensor 30 and the buffer detection spring 31 not only protect the device, but also balance the centrifugal force of the overall rotation of the sliding detection mechanism through the tension of the buffer detection spring 31, and can observe the roundness of the inner and outer diameters of the wind power flange through the detected value fluctuation of the pressure sensor 30, supplementing the detection data of the swing rod detection component, thereby improving the detection accuracy of the device.

[0062] Step Nine: When the first swing rod 19 moves to the upper end of the wind power flange, rotate the detection rotating block 43 to the vertical state. The second distance detector 46 on the detection rotating block 43 faces vertically downward towards the upper end surface of the wind power flange. When the lifting column 4 drives the first swing rod 19 to rotate, the second distance detector 46 on the first swing rod 19 detects the upper end surface of the wind power flange, thereby detecting the flatness of the upper end surface of the wind power flange.
