Device for measuring the deviation from the direction of movement between the two elements movable system connected at one point consists of a arm (R) tightly coupled to the drawing element (A) perpendicular to the direction of motion, the center of which passes through the point (O) to connect the two elements. the wire sensors (S1, S2) of the track located at the end of a stiff beam (R) at the same distance r from the point (O) and coupling of the measuring point (X), which is located at a distance r to the tensile element (B). Data on the change of the distance L1; L2 of the wire sensors (S1, S2) of track record device (D) intended for recording and transformation of the measured data. State of danger when set misalignment angle announce the warning device (V). Determining the deviation from a straight line movement misalignment angle can be obtained by calculation on the principle Tales circle distance measuring L1; L2. When the system moves directly measured the distance L1; L2 equal, therefore misalignment angle between the arm (R) and the runway has a value of 90 ø. In this situation, there is no deviation. When every other movement system arises deviation from the direction of motion, measure distances L1; L2 are different and the angle of misalignment () has a value of 90 ø. |
