Detailed Description
The utility model is described in further detail below with reference to the accompanying examples.
As shown in fig. 1, 2, 3, an online measuring device of tundish nozzle centering deviation in this embodiment, including scale 2, 2 initiating terminals of scale set up locating piece 1, 1 tip of locating piece has inside sunken arc wall, the minimum of arc wall is "zero-bit" of scale 2, the arc wall is laminated with 5 lateral walls of mouth of a river mutually, to the 5 radians of mouth of a river of the tundish of different models, the arc wall of the corresponding radian of customization, during the measurement, mouth of a river 5 can be hugged closely to the arc wall, can protect 2 initiating terminals of scale again. Trapezoidal measuring block 3 is established to the cover on scale 2, and measuring block 3's two parallel planes and scale 2 central line mutually perpendicular, measuring block 3 can remove along scale 2, and measuring block 3 removes to the initiating terminal from scale 2's end for 3 sides of measuring block are pasted in 6 edges of crystallizer copper pipe, and then measure the mouth of a river 5 around pouring and the four walls distance change of crystallizer copper pipe 6. The end of scale 2 sets up handle 4, portable on the one hand, and on the other hand prevents that measuring block 3 from following scale 2 landing.
A positioning hole is formed in the center of the measuring block 3, and a positioning bolt 7 penetrates through the positioning hole. When measuring 3 when a plane pastes in 6 edges of crystallizer copper pipe, screw up positioning bolt 7 and positioning bolt 7 top tight scale 2 for measuring 3 is fixed in on scale 2, and when scale 2 removed, measuring 3 also can not shift, moves scale 2 to spacious bright department record data, has guaranteed the accuracy of data.
