INDICATOR OF ULTIMATE INERTIA LOADS Russian patent published in 1995 - IPC

FIELD: measurement technology. SUBSTANCE: indicator has case 1 with rest, inertia body 2 pressed by spring 3 against rest and device to register ultimate loads. Bearing surface of inertial body is manufactured in the form of triangular collar. Annular groove is made in support of case over diameter of collar as well as n radial holes evenly arranged over circumference. Registering device of ultimate loads is produced in the form of rods-latches with lateral grooves spring-loaded relative to case 1, protruding above surface of case in initial condition and put into holes of support. In recessed condition rods-latches are held by ring collar pressed against support of inertia body which enters groove of rod-latch when it is raised from protruding into recessed position and releases it when inertia body breaks away from support. For provision of hemispherical diagram of sensitivity radius of ring collar is equal to distance from bearing surface to center of gravity of inertia body. For production of spherical diagram of sensitivity pickup is manufactured in the form of unit of two adjacent indicators. Limit switches shorting to frame or breaking control circuit with movement of rods-latches from initial position into operating one and back are built in into support of case to ensure remote control over condition of indicators while rods-latches move in support of case. EFFECT: improved authenticity of measurements. 4 cl, 4 dwg
