Description

Technical Field

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

[0002] Wind turbines are important new energy power generation equipment. Their basic structure is to install wind turbine mainframes through tower support, and convert wind energy into electrical energy at high altitude. The mainframe of wind turbines can rotate to adjust the windward side. In order to enable the mainframe to rotate, it is necessary to use bearings with flanges for connection. Usually, the diameter of the bearing flanges is relatively large. To ensure the stability of the mainframe, higher precision requirements are placed on the bearing flanges. The bearing flanges need to ensure that the roundness meets the standard and the stability of the flange connection is ensured. At present, the dynamic detection device for the ovality of the flange is usually used for detection before the installation of the wind turbine. However, after the flanges are connected, their accuracy will change as the service cycle increases. It is not convenient to detect the various accuracy indicators of the flanges in real time during the operation of the wind turbine. The inspection items involved are cumbersome and inefficient, and it is not convenient to test the clearance between the bearing flanges. As the service cycle increases, the flange deformation error gradually increases, and there are safety hazards. Flange bolts usually rely on manual inspections. Local bolt loosening can easily lead to flange deformation displacement. If not discovered in time, the flange accuracy deviation will be further increased. Summary of the invention

It can be installed on the wind turbine for real-time testing. The structure adopts a rotating detection part 4 to perform real-time testing on the axial offset error and radial offset error after the barrel flange 1011 in the wind turbine flange is connected to the flange bearing outer ring 102. The basic requirement that the flange bearing inner ring 103 and the barrel flange 1011 should be coaxial is used to indirectly reflect the roundness of the barrel flange 1011 and the flange bearing outer ring 102. The detection items can be effectively integrated. The radial and axial deviations can be detected at one time by detecting the sliding shaft 403 in conjunction with the detection fixing part 6, thereby improving the detection efficiency. At the same time, the structure is simple and reasonable, the problem response is more direct, and the problem can be repaired in time when it is found to ensure the normal operation of the wind turbine. The detection control part 5 can be used to adjust the alarm The trigger stroke, that is, the sensitivity, further improves the practicality of the present structure. No matter the axial or radial position of the detection slide shaft 403 and the detection ring 601 changes, the detection slide shaft 403 will be axially squeezed through the "V"-shaped groove on the inner side of the detection ring 601 or radially squeezed through the inclined surface of the "V"-shaped groove.

[0025] Embodiment 2, on the basis of embodiment 1, the detection fixture 6 comprises: a detection ring 601 and a rubber ring 602, the detection ring 601 is fixedly mounted inside the fan cylinder 101; a rubber ring 602 is fixedly mounted on the detection ring 601, and the rubber ring 602 is attached to the bottom of the flange bearing inner ring 103, which plays a role in dustproofing; a "V"-shaped groove is provided on the inner side of the detection ring 601; the clearance detection component 7 comprises: a propulsion hydraulic cylinder 701, a plug-in slider 702 and a guide shaft 703, the propulsion hydraulic cylinder 701 is fixedly mounted on the rotating mounting cylinder 401; a rubber ring 602 is fixedly mounted on the output shaft of the propulsion hydraulic cylinder 701 The plug-in slider 702; the end of the plug-in slider 702 is a sloped structure; the plug-in slider 702 is plugged into the inner side of the detection ring 601; the two sides of the plug-in slider 702 are respectively fixedly installed with guide shafts 703, and the two guide shafts 703 are respectively plugged into the rotating mounting cylinder 401; the clearance detection member 7 also includes: a brush sponge 704 and an electromagnet 705, the two sides of the plug-in slider 702 are respectively fixedly installed with brush sponges 704, and the brush sponges 704 are attached to the "V"-shaped groove on the inner side of the detection ring 601; the inside of the plug-in slider 702 is fixedly installed with an electromagnet 705; the electromagnet 705 is used to magnetically attract the detection ring 601, The brush sponge 704 is used to wipe and clean the detection ring 601. The clearance detection part 7 can assist in the active stress clearance test, improve the reliability of the connection between the flange bearing inner ring 103 and the flange bearing outer ring 102, and can apply stress for testing. The detection is more labor-saving and convenient, and there is no need to remove the flange bearing inner ring 103 and the flange bearing outer ring 102, so as to prevent the flange bearing inner ring 103 and the flange bearing outer ring 102 from being pressed and fitted with the roller due to the gravity of the main machine installed on the flange bearing inner ring 103, which is too heavy and the clearance range test is difficult to achieve manually. This structure can prevent After long-term use with the presence of clearance, the ovality gradually increases, causing a safety hazard. If there is wear clearance between the flange bearing inner ring 103 and the flange bearing outer ring 102, the cylinder flange 1011 and the flange bearing outer ring 102 will be pulled by the inserted slider 702, and displacement will occur between the flange bearing inner ring 103. At this time, the opposite detection slide shaft 403 will squeeze the detection ring 601, and the detection slide shaft 403 can squeeze the micro switch 504 to control the alarm, thereby realizing the clearance detection work. The three inserted sliders 702 can play a limiting role when inserted into the detection ring 601, thereby improving the stability of the structure when dealing with harsh environments.

[0026] The working principle of this embodiment is as follows: the distance between the micro switch 504 and the detection sliding shaft 403 is adjusted by sliding the detection distance adjustment shaft 503, and the positioning work can be performed by tightening the positioning bolt 502. After the wind turbine main engine is connected to the flange bearing inner ring 103 through the flange bolt, when the wind turbine is running and adjusting the windward side, it drives the rotating installation cylinder 401 to rotate. At this time, the rotating installation cylinder 401 will drive the detection sliding shaft 403 to slide in the "V"-shaped groove on the inner side of the detection ring 601. At this time, if the rollers between the flange bearing inner ring 103 and the flange bearing outer ring 102 are severely worn, the flange bearing inner ring 103 and the flange bearing outer ring 102 are no longer in a concentric position relationship, or the flange bearing outer ring 102 and the cylinder flange 1011 have elliptical deformation, the detection ring 60 1 will also be squeezed to produce an elliptical deformation. The detection slide shaft 403 will fit the detection ring 601 under the action of the spring. No matter the axial or radial position of the detection slide shaft 403 and the detection ring 601 changes, the detection slide shaft 403 will be axially squeezed through the "V"-shaped groove inside the detection ring 601 or radially squeezed through the inclined surface of the "V"-shaped groove. The detection slide shaft 403 can be retracted to touch the micro switch 504. At this time, the micro switch 504 can control the alarm control light 204 to light up and give an alarm prompt, which is convenient for the staff to know. The detection slide shaft 403 during the rotation process can fit the detection of each point on the inner side of the detection ring 601. The thrust hydraulic cylinder 701 relative to the detection control part 5 is used to drive the insertion slide 702 to move. During the process, the electromagnet 70 5-way electromagnetic suction detection ring 601, at this time, when the plug-in slider 702 moves, the fan barrel 101 can be pulled to move. If there is wear clearance between the flange bearing inner ring 103 and the flange bearing outer ring 102, the barrel flange 1011 and the flange bearing outer ring 102 on the fan barrel 101 will be pulled by the plug-in slider 702 and displaced between the flange bearing inner ring 103. At this time, the opposite detection slide shaft 403 will squeeze the detection ring 601. If the clearance is too large, the detection slide shaft 403 can squeeze the micro switch 504 to control the alarm to realize the clearance detection work. When the rotating installation cylinder 401 is driven to rotate by the main machine, it can drive the plug-in slider 702 to rotate to switch different detection positions. The staff can perform detection work regularly and at the same time, During the rotation process, the detection ring 601 can be wiped by the brush sponge 704, and the detection ring 601 can be inserted by driving the three plug-in sliders 702, but it can play a limiting role when the detection ring 601 is not frictionally fitted. It is used for reinforcement work in bad weather. The liquid replenishing bolt 203 is rotated to open the liquid-passing installation tube 201 for the first use of oil filling. When the wind turbine main engine drives the flange bearing inner ring 103 to rotate, the rotating detection part 4 can squeeze the pressing block 305 to squeeze the pressing plate 304 downward, compress the support spring 306, and press down the airbag 302. The air pressure is introduced into the liquid-passing installation tube 201 through the hose to test the sealing effect of each bolt connection on the flange bearing outer ring 102 in real time. Once the bolt is loose,The oil will penetrate into the outer ring 102 of the flange bearing. At this time, the amount of oil in the liquid-through installation tube 201 will decrease, and the tightness of the bolt connection can be known in time.
