Summary of the invention
Goal of the invention of the present invention is to provide a kind of large tunnel traverse measuring device and Installation and Debugging method thereof, makes that the flow field detection in the wind tunnel test is convenient, effectively improves detection efficiency.
The present invention is based on same inventive concept, have two independent technique schemes:
1, a kind of large tunnel traverse measuring device, comprise the traverse measurement rake, it is characterized in that: also have movably machine frame, two transmissions are supported leading screw and are fixed by chuck and machine frame respectively, traverse measurement rake is contained in transmission and supports on the leading screw, and can support leading screw along transmission and move up and down.
The machine frame bottom is provided with adjustable lower margin pole.
Also have connection seat and base, the bottom of connection seat is positioned at base, and angular contact articulated bearing is housed; The upper/lower terminal that leading screw is supported in transmission is contained in the connection seat.
Measure on the rake drive unit is housed, drive unit comprises motor, worm screw, worm gear screw, and worm screw is by motor-driven, and worm gear screw and transmission are supported leading screw and constituted screw pair, realize measuring rake moving up and down along screw mandrel by this screw pair.
2, a kind of Installation and Debugging method of aforementioned large tunnel traverse measuring device is characterized in that:
(1) the upper, middle and lower section of utilizing level meter that leading screw is supported in transmission is measured, and by the adjusting to chuck, makes two leading screws parallel;
(2) on the horizontal steel plate of machine frame, place level meter, utilize level meter and the lower margin bottom machine frame to prop up pole pair two leading screws and carry out vertical adjusting;
(3) top board and the base plate that leading screw and wind-tunnel is supported in transmission by upper and lower connection seat fixed, and be last, removes mobile machine frame.
The bottom of connection seat is positioned at base, and angular contact articulated bearing is housed.
When fixed conveyor supports leading screw, unclamp the radial location screw on the connection seat earlier, connection seat can be moved up and down, then, the base plate and the top board of base and wind-tunnel are fixed, last, screw the axial location nut on the connection seat, simultaneously, hold out against the radial location screw on the second line of a couplet joint chair.
The beneficial effect that the present invention has:
The present invention supports leading screw by machine frame movably to transmission and installs and locate, and measures rake and can support under the driving of drive unit that leading screw is upper and lower to be moved along transmission, carries out flow field survey.The present invention can effectively reduce artificial moving and fixation measuring rake number of times, has guaranteed to measure the precision and the accuracy of rake, reduces labour intensity, reduces the frequency of wind-tunnel open and close in the chamber; It is convenient that the leading screw dismounting is supported in machine frame and transmission, improved the efficient in conversion pressure measurement rake measurement cross section.
The present invention can effectively improve the rigidity and the intensity of pressure measurement rake, at normal pressure 130m/s, can safe operation the wind speed of supercharging 90m/s under, simultaneously owing to adopt spherical hinge structure in the connection seat, guaranteed transmission support leading screw be connected with test section hole wall stablize firm.
