Description
Technical field
The utility model relates to a kind of centring means, specifically is a kind of centring means for boiler's tube-plate.
Background technology
China is a manufacturing powerhouse, and Industrial Boiler has very important effect in industrial production.Yet large-sized boiler, particularly super large boiler are because its volume is big, weight is big, always occur in processing technology that the location is difficult, the difficult shortcoming such as processing that is unfavorable for of clamping, and specially its design often is tending towards complicated during frock clamp, on the contrary too much increase production cost.In the production of Industrial Boiler, particularly partly there is a large amount of holes need bore processing at the boiler body tube sheet of producing DZL, WNS series, but because its volume and weight are bigger, be not easy to use that drill jig clamps, locatees, processes, operation such as dismounting again.How to be felt relieved at tube sheet planar section centering by line teams and groups in the production, each hole site line that draws is again transferred to the boring processing of drilling machine place then.
In the routine operation, whole scratching process measures, determines that auxiliary magnet all uses tape measure.Because arch tube sheet convex part is made of different ellipses in the reality, the transition of itself and straight portion also is seamlessly transitting of its ellipse and straight line, and the boundary line of searching straight portion is difficult, causes inevitably introducing error in measuring process.The routine operation method is many in practical operation is in addition rule by a people, and a people measures check and correction, does change again, wastes man-hour, inefficiency.The forward and backward tube sheet center of circle skew that above reason causes causes smoke pipe assembling back integral inclination greatly, departs from center or distortion, even the problem of assembling difficulty happens occasionally.
Summary of the invention
At the problem that above-mentioned prior art exists, the utility model provides a kind of centring means for boiler's tube-plate, only needs a people just can determine the center of circle of boiler's tube-plate fast and accurately.

Further, left tangent arm and right tangent arm are provided with adjustment hole, and an end of left connecting rod and an end of right connecting rod are provided with connecting pin, and described connecting pin is connected with left connecting rod, right tangent arm the tangent arm in a left side respectively by adjustment hole with right connecting rod.
Further, also comprise handrail, fast pulley and universal wheel, handrail is fixed on the mount pad, and fast pulley and universal wheel are fixed on the bottom of mount pad.
Compared with prior art, the utility model is simple in structure, and is easy to use, utilized geometry principle design, only needs a people just can determine the center of circle of boiler's tube-plate fast and accurately.
