Breaker, hitting transmission member, Wariiwa tools and disruption methods

摘要

The present invention rock, by the piston to the rear end of the wedge member that the front end portion of the tapered shape is inserted between the plurality of pressing members which are inserted into drilled formed on the processing object such as a rock and concrete structures the task of the plurality of pressing members are moved radially outwardly of the drilling by giving impact to fracture around the drilling, the performed while preventing the occurrence of blank beating. The apparatus includes a piston inside the cylinder portion is disposed between the insertion space, by receiving in the rear end face of the impact by the piston while abutting the distal end face on the rear end surface of the loosely inserted to the wedge member into the insertion space in striking transmitting member for transmitting the impact by the piston in the wedge member, corresponding to the rear end face of the wedge member is a curved convex surface, the tapered tip end portion of the striking transmission member toward the leading end face of the striking transmission member shape the distal end surface of the striking transmission member has a rear end surface and the sliding contact can be concave curved surface of the wedge member together with the.FIELD 4
