Bar, U-typed pawl, the supporting screw rod of creep measurement points seat；For " mouth " shape frame hub on jet chimney, creep measurement points seat is screwed in creep measurement points
On the supporting screw rod of seat, air-bubble leveling ruler is set on the side of " mouth " shape framework four, caliber adjusting screw rod is set in " mouth " shape framework surrounding,
The caliber adjusting screw rod is located on two symmetry axis of " mouth " shape framework；Entirely " mouth " shape framework is fixed by U-typed pawl
On pipeline.
The application method of the installation tool for jet chimney creep measurement points, including
Step 1, " mouth " shape frame hub on jet chimney,
Step 2, four creep measurement points seats are screwed on the supporting screw rod of creep measurement points seat,
Step 3, observation " mouth " shape frame upper side air-bubble leveling ruler, adjusting screw rod observation " mouth " shape frame upper side air-bubble leveling ruler,
" mouth " shape frame upper side frame is adjusted to level,
Step 4, regulation caliber adjusting screw rod, creep measurement points seat are pressed on jet chimney, and adjust U-typed pawl " mouth " shape
Framework is fixed perpendicular to jet chimney axis；
Step 5, creep measurement points seat and jet chimney welded.
This installation tool is applied to the pipeline of different tube diameters, efficiency high, can be applied to not by adjusting caliber adjusting screw rod
Creep measurement points with caliber is installed, and can install a section creep measurement points simultaneously, rapidly and efficiently, is repeated and is utilized.
