Description

Technical Field

[0001] The invention relates to the technical field of wind power flange measurement, and in particular to an ovality detection tool for a wind power flange. Background Art

[0002] Wind turbine flanges are mainly used in the connection between wind turbine towers. By welding the flanges at the ends of wind turbine towers, subsequent assembly work is facilitated. In the manufacturing of wind turbine flanges, because wind turbine flanges play an important role in the installation stability of wind turbine towers, it is necessary to test their processing accuracy in the manufacturing of wind turbine flanges to avoid excessive errors such as ovality that affect subsequent assembly and safety. The end face accuracy of the flange will also directly affect the parameters such as ovality after the flange is installed. At present, the ovality detection of wind turbine flanges mostly uses manual inspection tools for related inspection work. Thanks to the flexible inspection, it is also widely used. However, for flanges with larger volumes, the inspection work is time-consuming and labor-intensive, and it is difficult to ensure measurement accuracy. The measurement data is mostly diameter measurement. At the same time, it is not convenient to axially press and position the flange. The axial deformation of the flange itself is not convenient for automatic control during inspection, which affects the measurement accuracy. It is also not convenient to conduct comprehensive verticality and aperture position inspections for the machining accuracy of the flange hole and the end face. Poor flange hole accuracy will directly affect the flange assembly quality. Summary of the invention

The verticality test piece 6 is used in conjunction with the end face adaptation detection piece 5 to perform adaptation detection on the end face of the flange, and the flange hole processing accuracy of the flange end face can be detected in real time. The structure uses the docking tapered column 603 to cooperate with the detection shaft 504, which can realize real-time insertion of the flange hole for detection. The tapered detection structure is used to move on the flange end face to measure the flatness of the flange end face. At the same time, the tapered structure can be used to test the diameter of the flange hole and the verticality of the opening in turn. The end face fitting cylinder 502 can be used to fit the flange end face in real time, and the subsequent measurement work has higher accuracy, which can effectively ensure the quality of flange hole detection, and multiple parameter detection work can be performed at one time.

At the same time, under the extrusion of the upper pull spring 604, the vertical detection frame 601 can drive the docking conical column 603 to insert into the bottom flange hole. If the value displayed on the detection axis 504 corresponding to the top of the docking conical column 603 is inconsistent with the value of the detection axis 504 itself inserted downward, it proves that the opening positions on both sides are offset and not vertical. The bottom docking conical column 603 is not fully inserted into the flange hole, which means that the verticality of the flange hole is not up to standard at this time. The conical structure of the docking conical column 603 and the detection axis 504 can be detached from the flange hole to achieve fitting on the flange end face detection. The structure is more reasonable and the end face flatness can be quickly displayed. ;

[0025] Embodiment 2, on the basis of embodiment 1, the magnetic pressing member 7 comprises: a magnetic traction block 701 and an electromagnet 702, the magnetic traction block 701 is fixedly mounted on the bottom of the fitting installation block 301; an electromagnet 702 is fixedly mounted on the bottom of the magnetic traction block 701; the electromagnet 702 is used for magnetic detection support disk 101; two rollers are rotatably mounted on the bottom of the magnetic traction block 701, and the two rollers at the bottom of the magnetic traction block 701 are attached to the detection support disk 101, and the magnetic pressing member 7 can assist in pulling the sliding cylinder 201 by magnetic attraction, and drive the pressing roller 302 on the fitting installation block 301 to press the flange, so that the measurement of the flange is more stable, because the larger diameter flange has a local poor fit after being placed on the flange support ring, so as to avoid the larger diameter flange from not being tightly fitted to the flange support ring axially, and the reliability of the detection data can be improved, because when the actual flange is installed, the flanges will maintain a planar fit under the connection of bolts, and the magnetic control adopted in this structure is also simpler and more convenient.

[0026] The working principle of this embodiment is as follows: first, the flange is hoisted on the flange support ring 106. It is sufficient to simply make it concentric without precise alignment. When hoisting the flange, the adjusting screw 402 is rotated to drive the adjustment frame 401 to move outward to facilitate the placement of the flange. After the flange is placed, the adjustment frame 401 is driven to move inward and reset. By starting the electromagnet 702 to magnetically detect the support plate 101 and supporting it with the roller at the bottom of the magnetic traction block 701, the automatic adapter 2 can be driven to move downward as a whole, driving the two moving rollers 306 and the two rollers on the fitting wheel frame 204 to be placed inside the flange. At the same time, the pressing roller 302 will also be driven to press the flange downward for flattening. Subsequently, the reverse screw 202 is rotated to drive the two sliding blocks 203 to expand outward at the same time. The flange is clamped in the center by using two moving rollers 306 and the two rollers on the fitting wheel frame 204. During the process, the adapter positioning disk 102 can be driven to adjust the initial position. Then the positioning bolts 105 can be tightened to position the adapter positioning disk 102. At this time, the position of the adapter positioning disk 102 is the center point of the two moving rollers 306 and the two rollers on the fitting wheel frame 204. Then the positioning pin 305 is pulled out, and the moving roller 306 is driven to rotate by driving the rotary motor 307, which drives the automatic adapter 2 to rotate around the flange as a whole. The propulsion sliding shaft 303 that loses its limit will push the moving roller 306 to fit the inner ring of the flange in real time under the pressure of its own sleeve spring. If the ellipticity of the inner ring of the flange deviates at this time, its diameter will change. At this time, the two moving rollers 306 are The change in the distance between the roller 306 and the two rollers on the fitting wheel frame 204 can drive the elastic reading disk 103 under the sliding cylinder 201 to deflect, and the reading on the elastic reading disk 103 can be observed at this time. The readings in various directions on the elastic reading disk 103 can be observed in real time to know the offset at this time, and the display is more comprehensive to reflect the elliptical degree of the wind turbine flange. By using the end face fitting tension spring 503, the end face fitting cylinder 502 can be driven to stick to the flange end face by pulling. By using the multi-directional adaptation of the end face adapter ball 501, the end face fitting cylinder 502 can be vertically attached to the flange end face. By rotating the adjusting screw rod 402 to control the retraction of the push adjustment frame 401, the detection shaft 504 can be driven to correspond to the center of the flange hole. As the two moving rollers 3 06 drives the fitting installation block 301 to move around the inner side of the flange, which can drive the detection shaft 504 to be inserted into the flange hole for detection. By utilizing its tapered structure, if the depth dimension of the detection shaft 504 inserted into the flange hole is too small or too large, it reflects the flange hole diameter deviation or the opening position of the flange hole on the flange. The opening position is biased inward or outward. At the same time, under the pressure of the upper pull spring 604, the vertical detection frame 601 can drive the docking tapered column 603 to insert into the bottom flange hole. If the value on the detection shaft 504 corresponding to the top of the docking tapered column 603 is inconsistent with the value of the detection shaft 504 inserted downward, it means that the verticality of the flange hole is not up to standard, which will cause the docking tapered column 603 to deviate when inserted into the flange hole, and it cannot correspond to the reference value.After the flange hole detection is completed by the docking conical column 603 and the detection shaft 504, with the driving of the fitting installation block 301, the conical structure of the docking conical column 603 and the detection shaft 504 can be disengaged from the flange hole to achieve the detection of the flange end surface. During the process, the scale on the detection shaft 504 can be manually observed in real time; after the ovality measurement is completed, the handles on the two push slide shafts 303 can be manually pulled back, and the positioning pins 305 can be inserted here for positioning, which is convenient for the subsequent flange measurement work.
