To provide a core-regulating apparatus capable of surely sticking a movable part of a connector in a dust collecting device for making a dust collecting hood of a machine of a coke oven communicate with a stationary duct on the ground to a connection hole of the stationary duct even if the deviation of a core is produced between the connector and the connection hole of the stationary duct, neither leaking a dust gas to the outside, nor reducing dust collecting ability by suction of open air from the connection hole and lowering the installation cost.
A base part of a fixing part 8 of each connector of plural connectors is connected to a dust collecting hood 7 of a machine side of a coke oven by a double hinge type quadrilateral mechanism. A guide roller 13 attached to each a movable part 9 of each connector is guided by a guide frame 16 fixed to a stationary duct connection hole 25 and the center of the movable part 9 of the connector is corrected so as to correspond to the center of the connection hole. The movable part 9 of the connector is stuck fast to the connection hole 25 of the stationary duct to prevent the leakage of a dust gas to the outside and reduction in duct collecting ability.
