A flap opening-and-closing casing assembly that can remotely control volume of air supplied into the coke oven even at a place distanced far from a coke oven, and can accurately control volume of air required in the coke oven by adjusting opening and closing amounts of flaps using a numerically controllable motor is provided. A flap opening-and-closing casing assembly comprises: a power transmission part operated by a motor and a speed reducer, wherein a first pinion gear and a second pinion gear(75a) are respectively connected to an upper portion of a first pinion drive shaft(3) and a lower portion of a second pinion drive shaft(7) interlocked with a drive shaft, and right rack gears(76,76a) and left rack gears(77,77a) are interlocked with each other to open or close both right flaps and left flaps by moving the flap 1(30) and the flap 1a(30a) respectively when the right rack gears and the left rack gears are operated side to side; and an air supply box body(B) having a rectangular shape and comprising a flap member having left flaps including a flap 1(30), a flap 2(31), a flap 3(32) and flap 4(33) and right flaps including a flap 1a(30a), a flap 2a(31a), a flap 3a(32a) and a flap 4a(33a). |
