MULTI-POINT SIMULTANEOUS RUPTURE DEVICE

PURPOSE:To rupture simultaneously and automatically the multi-point by holding the linking condition with a pair of rupture claws as an expanding condition by the spacer provided to the piston shaft of the hydraulic cylinder, shrinking instantaneously the piston shaft and detaching the rupture claw. CONSTITUTION:The arm of a sampling steel tower and the loading device are linked with a linking cylinder 12 which has a linking member 11 to have a pair of rupture claws 10 and accommodating part to be able to accommodate the pair of the rupture claws 10 at the front part and fits a hydraulic cylinder 13 at the rear part. The rupture claws 10 are attached, freely oscillatably to the linking member 11 so that the tip pat can take the expanding condition and the shrinking condition, the accommodating pat 12A of the linking cylinder 12 is constituted so that the rupture claws 10 can be detached in the shrinking condition and detained in the expanding condition. By a spacer 14 provided at a piston shaft 13A of the hydraulic cylinder 13, from the condition to link and hold the tip part of the rupture claws 10 in the expanding condition, the piston shaft 13A is shrinked instantaneously, and then, the rupture claws 10 can be instantaneously detached.
