Method for measuring wear in the lining of a container provided with a pivoted axle and an opening, and a container

Claim 1

A method for measuring wear in the lining of a container provided with a pivoted axle and an opening, in which method fixing of the coordinate systems (16, 17) set for a measuring device (1) and the container (6) is performed by the measuring device (1) emitting and receiving optical radiation, said fixing comprising mathematically combining the coordinate systems (16, 17) of the measuring device (1) and the container (6) by measuring the position of specific fixing points (P1, P2, P3) in the coordinate system (16) of the measuring device (1) and by measuring angle data (α 1 , α 2 ) on the inclined position of the container (6), and after the fixing the lining (10) on the inner surface of the container (6) is measured by directing optical radiation to the lining (10) and receiving the radiation reflected from the lining (10), characterized in that the fixing is performed by measuring the position of the fixing points (P1, P2, P3) mounted in connection with the container in the coordinate system (16) of the measuring device (1) in a situation where the container opening faces away from the measuring device while the measuring device is directed towards the bottom of the container, whereafter the container (6) is rotated around its pivoted axle (11) to a position in which the opening (9) of the container (6) faces the measuring device (1), and that the fixing is performed utilizing the angle difference between angle data (α 1 ) obtained during the measurement of the fixing points (P1, P2, P3) and angle data (α 2 ) obtained after the rotation of the container, said angle difference being obtained by angle measurement known per se, measuring the inclination of the container (6).
