Background technology
At present, MW class wind turbine is the advanced technology of China from outer introduction, and this is the engineering of an environmental protection, is following trend.The major product that wind-powered electricity generation subsidiary factory of motor company makes is a 1.5MW permanent magnet direct-driving aerogenerator stator, and stator core adopts the segmental punching closed assembly to form, and in order to guarantee the globality behind the closed assembly, it is very important that the control of the quality of stator support just seems.Yet the stator support of large-size machine is a huge object, and existing detection frock is difficult to detect and control to the right alignment of many bulk especially stator support φ 4140 with φ 1270 more, and then has influenced the quality of stator support.In order better to control the quality of stator support; Necessary method and the frock of finding out a kind of energy measurement stator support φ 4140 and the right alignment of φ 1270 supports such as large-size stator such as class such as grade, whether qualified the frock that requires to design become one of support foundation to the detection of support.Therefore need further to improve.
Summary of the invention
The object of the invention exactly in order to overcome the deficiency that existing stator support detects frock, proposes a kind of right alignment that can satisfy the large-size stator support of measuring and detects aerogenerator stator support right alignment detection method and the device that requires.
The technical solution adopted for the present invention to solve the technical problems is: aerogenerator stator support right alignment detection method; Utilize dial gauge that aerogenerator stator support right alignment is detected; The measuring seat main body that a center mounting hole with stator support matches is installed on the center mounting hole at stator support; In measuring seat v main body one rotatable gage beam is installed, gage beam leans on the cylindrical of stator support to be inserted with a sounding rod, and sounding rod is distributed with dial gauge up and down; Through the wheel measuring arm, aerogenerator stator support right alignment is detected by being installed in the dial gauge that sounding rod distributes up and down.
Aerogenerator stator support axiality detection device according to above-mentioned measuring method provided is: a kind of aerogenerator stator support axiality detection device comprises measuring seat main body, turning axle, gage beam, counterweight reinforcement, sounding rod and dial gauge.Wherein, the measuring seat main body is divided into locating flange and measuring seat sleeve two parts, and locating flange and measuring seat sleeve connect as one through reinforcement; On the measuring seat sleeve midline position of measuring seat main body, embed turning axle; Rotating shaft terminal is equipped with taper roll bearing, and the bottom of turning axle is blocked with round nut, prevents that turning axle from skidding off in rotary course; The top of turning axle is connected with gage beam; The counterweight reinforcement is being fixed in the upper end of gage beam, and the end of gage beam has also been installed three dial gauges with high-head knurling screw fixation measuring bar on the sounding rod.
The present invention is directed to the detection of the stator support of present large-scale wind driven generator, the quality of control support, thereby the quality of assurance stator.This right alignment detects frock can satisfy the control of MW class stator to right alignment.
