STAND FOR DYNAMIC AND TECHNOLOGICAL TESTS OF SPRINKLING MACHINES Russian patent published in 1999 - IPC

FIELD: mechanical engineering. SUBSTANCE: stand is designed to test sprinkling machines, accelerated tests of volumetric structures of girders with water-feeding pipe-line, of mobile bearing trolley, immobile support, sprinkling apparatuses, driving units and automatic equipment of sprinkling machines. Stand includes circular vessel 4 and rotary frame 6 with bearing trolley 7. Circular vessel 4 is aligned with track of bearing trolley 7 and is manufactured in the form of set of arc sections 11-19 installed with alternation in the following sequence: testing technological platform 11, natural ditch 12 of track in earth of testing ground, simulation obstacle 13 with arrangement of rods in ditch at different depths, simulation obstacles 14, 15 with stretching and compressing effects acting along rotary frame 6 with reference to immobile support 5, simulation obstacle 16 protruding above ground interconnected with crossing ladders. EFFECT: enhanced technical and operational reliability of sprinkling machines thanks to approximation of testing conditions to real ones by way of simulation of wide spectrum of real conditions of operation. 16 cl, 13 dwg
