1. A coke-oven repairing apparatus comprising: a traveling carriage which travels in the direction of coke oven battery with the carriage straddled on rails placed on the top of a coke oven; a traversing carriage provided on said traveling carriage, which moves in the direction orthogonal to the direction of coke oven battery; and a working device for making repairs on the oven walls within the coke oven which is mounted on said traversing carriage, said working device includes:
a guide post which stands on said traversing carriage, and is also coupled, at its lower end portion, to a supporting portion provided on the traversing carriage through a pivot shaft;
a lance which ascends or descends along the guide post; and
a lance oscillating means which oscillates said guide post between a forward-tilted posture and a backward-tilted posture using said pivot shaft as the fulcrum to tilt said lance inserted in a coke-oven carbonizing chamber through a charging-hole, within the carbonizing chamber,
wherein the lance oscillating means include:
an extendable device which extends and contracts and is coupled to the guide post and the traversing carriage; and
a control device which sets a fulcrum of the lance to near the center of the charging-hole and also to near the depthwise center of the charging-hole, and interlocks a driving of the extendable device and a driving of the traversing carriage for maximizing the oscillating angle of the lance inserted in the carbonizing chamber, within a range which prevents the lance from contacting with the charging hole.
