REPAIR APPARATUS FOR COKE OVEN

摘要

A repair apparatus for a coke oven, comprising a traveling carriage (3) put across rails laid down on the coke oven and traveling in the direction of the furnace group of the coke oven. A transverse carriage (4) moving in a direction orthogonal to the traveling direction is installed on the traveling carriage (3). A work device (5) for repairing a furnace wall on the inside of the coke oven is mounted on the transverse carriage (4). The work device (5) is characterized by comprising a guide post (31) vertically installed on the transverse carriage (4) and having a lower end part connected, through a pivot shaft (42), to a support part formed on the transverse carriage, a lance (32) lifting along the guide post (31), and a derricking device (45) swinging the lance (32) inserted through an insert hole into a coke oven carbonization chamber in a furnace length direction by swinging the guide post (31) about the pivot shaft (42) between a forward tilted attitude and a backward tilted attitude.
