Abstract
Abstract A measuring apparatus for determining the position of a roller apron of a continuous casting installation comprising at least one partially curved roller apron, wherein calibrated plumb bobs or lines can be applied to coordinate-measuring points of the roller apron for projecting the position of the measuring points in the x-axis or z-axis into a substantially horizontal measuring plane. Along the roller apron there are applied at a number of such coordinate-measuring points the calibrated plumb bobs or lines at the reference distance in the y-axis between the momentary or related measuring point and the measuring plane.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
120 words
A measuring apparatus for determining the position of a roller apron of a continuous casting installation, comprising: at least one partially curved roller apron; means for supporting said roller apron with respect to a base defining a substantially horizontal measuring plane; said apron containing a number of coordinate-measuring points at which there are means for mounting plumb lines for projecting the position of the measuring points in the x-axis or z-axis into said substantially horizontal measuring plane; said plumb lines constituting calibrated plumb lines which are applied along the roller apron at said number of the coordinate-measuring points and each have a length in the y-axis corresponding to the desired distance between the related measuring point and the measuring plane.
Claim 2
Dependent Claim
120 words
A measuring apparatus for determining the position of a roller apron of a continuous casting installation, comprising: at least one partially curved roller apron; means for supporting said roller apron with respect to a base defining a substantially horizontal measuring plane; said apron containing a number of coordinate-measuring points at which there are means for mounting plumb lines for projecting the position of the measuring points in the x-axis or z-axis into said substantially horizontal measuring plane; said plumb lines constituting calibrated plumb lines which are applied along the roller apron at said number of the coordinate-measuring points and each have a length in the y-axis corresponding to the desired distance between the related measuring point and the measuring plane.
Claim 3
Dependent Claim
45 words
The measuring apparatus as defined in claim 1, further including: means on said base defining a measuring channel arranged laterally of the roller apron; said measuring plane being disposed below the roller apron in said measuring channel; and said plumb lines penetrating said measuring plane.
Claim 4
Dependent Claim
39 words
The measuring apparatus as defined in claim 2, further including: means defining closed vertical channels having open upper and lower ends; said plumb lines being arranged in said closed vertical channels between the coordinate-measuring points and the measuring channel.
Claim 5
Dependent Claim
24 words
The measuring apparatus as defined in claim 1, wherein: each of said plumb lines has a plumb line wire formed of INVAR (iron-nickel alloy).
Claim 6
Dependent Claim
25 words
The measuring apparatus as defined in claim 1, further including: means on said base defining measuring channels arranged to each side of the roller apron.
Claim 7
Dependent Claim
29 words
The measuring apparatus as defined in claim 5, further including: transverse channel means on said base for interconnecting the measuring channels arranged to both sides of the roller apron.
Claim 8
Dependent Claim
47 words
The measuring apparatus as defined in claim 1, further including: each plumb line having a reference position in the x-axis or the z-axis respectively; and setting sleeves anchored in said base for marking the reference position of each plumb line in the x-axis or the z-axis, respectively.
Claim 9
Dependent Claim
22 words
The measuring apparatus as defined in claim 1, wherein said mounting means comprises: rustproof pins mounted in bores at the coordinate-measuring points.
Claim 10
Dependent Claim
40 words
The measuring apparatus as defined in claim 1, further including: inductive measuring transmitters provided for said plumb lines to sense the positions thereof; and a monitoring device connected to said inductive measuring transmitters for giving an indication of said positions.
Claim 11
Dependent Claim
18 words
The measuring apparatus as defined in claim 1, further including: vibration damping means provided for said plumb lines.
Claim 12
Dependent Claim
115 words
A measuring apparatus for determining the position of a strand guide of a continuous casting installation, comprising: at least one strand guide; means for supporting said strand guide with respect to a base defining a substantially horizontal measuring plane; said strand guide containing coordinate-measuring points at which there are means for mounting plumb lines for projecting the position of the measuring points along a substantially vertical axis into said substantially horizontal measuring plane; said plumb lines constituting calibrated plumb lines which are applied along the strand guide at least at given ones of the coordinate-measuring points and each have a length corresponding to the desired distance between the related measuring point and the measuring plane.
Claim 13
Dependent Claim
115 words
A measuring apparatus for determining the position of a strand guide of a continuous casting installation, comprising: at least one strand guide; means for supporting said strand guide with respect to a base defining a substantially horizontal measuring plane; said strand guide containing coordinate-measuring points at which there are means for mounting plumb lines for projecting the position of the measuring points along a substantially vertical axis into said substantially horizontal measuring plane; said plumb lines constituting calibrated plumb lines which are applied along the strand guide at least at given ones of the coordinate-measuring points and each have a length corresponding to the desired distance between the related measuring point and the measuring plane.
