It determines that measuring device placement reaches horizontal, the quarter indicated in semi circular surface protractor dial can be fallen according to suspension line on pointer
It spends line position and reads distributor chute tilt values.
The utility model has the beneficial effect that will calculate acquisition distributor chute inclination data indirectly in the past is changed to use angulation
The direct measurement angle of device, measurement operation intuitive and convenient, simple and fast, reliability and accuracy rate are high, can provide standard for blast fumance
True operating parameter.
Lean rod is made in four points of intercepted length=400mm stainless steel tube one, plays and resists distributor chute U-type groove body convex surface
The effect of backboard measures lean rod midpoint, then connecting rod is made in four points of intercepted length=6m stainless steel tube one, by connecting rod
One end is vertical with lean rod midpoint to being welded and fixed after positive positioning；One piece of stainless steel plate of thickness δ=5mm is taken, is with length=150mm
Radius draws semicircle in surface of steel plate, makes and intercepts semi circular surface with cutter behind the center of circle, and in the semi circular surface side mark amount cut down
Semi circular surface protractor dial is made in angle device scale, can directly read angle value, the other side of semi circular surface is without scale；Keep semicircle
The straight flange and disk of face protractor dial are parallel with lean rod, the center of circle and company by semi circular surface protractor dial without scale side
The other end of extension bar after positive positioning vertically to being welded and fixed, and one end of neighbouring semi circular surface protractor dial is solid in connecting rod
Determine level meter, reaches horizontal to determining device placement in measurement, avoid measured deviation；Intercepted length=50mm, diameter phi=
Pointer is made in one, round steel of 4mm, and one end and the mark center of circle of scale side on semi circular surface protractor dial is vertical right
It is welded and fixed after positive positioning, plays the role of suspension line pendant；Line pendant is suspended on pointer by self weight always in vertical configuration
State, and neighbouring semi circular surface protractor dial is swingable can fall the graduation mark position of instruction from protractor scale according to line
The angle distributor chute α numerical value is read in disk.
Before measurement, under blast furnace routine maintenance, Status of hugh wind, opening one manhole of furnace roof, which is used as, is put into furnace for protractor
Interior channel and observation is used, and the side backboard face that distributor chute is transferred to its U-type groove body is observed to the position of manhole；It uses
When the protractor, holds connecting rod and be put into the one end for being fixed with lean rod in furnace from furnace roof field observation manhole, be fixed with semicircle
Lean rod is resisted the backboard on distributor chute U-type groove body convex surface outside furnace by one end of face protractor dial, and with along distributor chute
The bus of length direction surface of revolution is overlapped, and determines that protractor placement reaches according to level meter display adjustment connecting rod upper and lower position
Level can read distributor chute according to the graduation mark position that suspension line pendant indicates in semi circular surface protractor dial on pointer
The angle α numerical value.
The utility model has the advantages that
