REFRACTORY DISMANTLING MACHINE OF MIXER CAR AND REFRACTORY IMPROVING METHOD OF MIXER CAR

摘要

PROBLEM TO BE SOLVED: To perform a whole monolithic refractory improvement of a mixer car in a short time, reduce the usage of the monolithic refractory, and elongate the service life of the monolithic refractory compared with that by conventional emergency measures.;SOLUTION: This refractory dismantling machine comprises a moving member movable in the longitudinal direction of the mixer car 1, a support member mounted on the moving member, a disk-shaped rotary device 14 attached to the tip of the support member, rotating around a central shaft by a rotation drive body, and axially vibrating by a vibrator, a positioning mechanism fitted with multiple fracture-type cutting edges 31 attached to the front surface of the disk-shaped rotary device to axially advance and retreat, disposed with the rotatably fitted cutting edges and the disk-shaped rotary device inside the mixer car, pushing them to the inner surface of the mixer car, and turning and moving in the circumferential direction and/or longitudinal direction, and a control device fixedly retaining the position during excavation or the pushing force of the disk-shaped rotary device.;COPYRIGHT: (C)2003,JPO
