FOOT PUSHER FOR PRESS-FIT SOIL NON-MOVING TYPE PIPE-BODY BURYING MACHINE

摘要

PURPOSE:To conduct operation automatically by installing a positioning lever to a movable carriage, in which front and rear section movable trucks are connected by hydraulic cylinders, and receiving reaction generated at the time of the operation of the expansion and contraction of the hydraulic cylinders by grooved rails. CONSTITUTION:When a pipe body 3 is pushed against and mounted to the front end of a front section movable truck 5 and the piston rod of a hydraulic cylinder 10 is elongated in the direction of the inside of soil, the front section movable truck 5 is moved in the direction of the inside of soil. Reaction generated at the time of movement is received by grooved rails 4, with which the noses of positioning levers 8' are engaged, while the movable truck 5 is ridden across protrusions 4' among the grooves of the grooved rails 4 against the force of push pressure and shifted. The pipe body 3 is pushed into soil and stopped, and the front end of the front section movable truck 5 and the pipe body 3 are separated. Accordingly, front and rear movable trucks 5, 12 are moved before and behind by the operation of the expansion and contraction of the hydraulic cylinder, and the movable trucks can be shifted without human working.
