Among three pieces of fixed blocks, strip-shaped hole corresponding position is equipped with bolt hole on the movable bearing support side and fixed block, and corresponding
Bolt hole and strip-shaped hole between pass through adjustable bolt connect；Circular through hole, the survey are equipped at the center of the movable bearing support
The lower end of amount pointer is inserted in the circular through hole.
It is equipped with internal screw thread in circular through hole at the movable bearing support center, measurement pointer lower end is equipped with matching outer
Screw thread, and measure pointer lower end and be screwed in circular through hole.
Gap≤10mm between the movable bearing support and bottom plate.
Large tunnel installs the auxiliary method of adjustment of concentricity adjustment auxiliary device, it is characterised in that it includes following step
It is rapid:
1) prepare several large tunnel installation concentricities and adjust auxiliary device；
2) both ends on the outside of the cylinder of each section of wind-tunnel respectively set a large tunnel installation concentricity adjustment auxiliary dress
It sets, all large tunnel installation concentricity adjustment auxiliary devices are respectively positioned in the same angle of cylinder, and measurement can intervisibility；
3) position that pointer is measured on all large tunnel installation concentricity adjustment auxiliary devices is adjusted, so that all measurements
The kernel of section of pointer top and section cylinder corresponding position keeps identical relative position；
4) close up all sections, the top of each measurement pointer is made to be located along the same line.
The position that pointer top is measured described in step 3) is upper and lower to realize by adjustable bolt and pulling and pushing for measurement pointer
Left-right and front-back is adjusted.
The beneficial effects of the present invention are: the device will be led to outside cylinder outside the wind-tunnel inner barrel measurement point of internal not intervisibility
Portion measures, and solves the problems, such as obstructed optionally lower axis, absolute altitude, the bad measurement of concentricity.Pass through strip-shaped hole, adjustable bolt
And the adjustment of scalable measurement pointer, precise positioning measurement point guarantee tubular axis, absolute altitude, concentricity accuracy.
