Method and device for the positioning of operating units of a coal filling cart at the filling openings of a coke oven

摘要

The invention relates to a method of positioning service equipment of a coal-charging larry cart at charging ports of a coke oven, wherein a rail-guided larry cart is moved on the roof of a coke oven and is positioned at locations known by a machine control system and corresponding to charging ports in the oven roof in order to charge the oven chambers, and wherein then at least one piece of service equipment of the coal-charging larry cart is guided to the charging ports by horizontal biaxial positioning movements. According to the invention, an optical measurement method is used after each positioning of the larry cart to detect the coordinates of at least one marking that is applied to the oven roof and that has a fixed relationship with the center axis of a charging port within a measurement field that is predefined by the measurement method and to compare them with reference values that are stored in the machine control system for the marking. The deviations between the measured coordinates and the coordinates stored in the machine control system are determined for both axial directions. Differential values are then taken into account as correction values during the positioning movement of the piece of service equipment. The subject matter of the invention is furthermore formed by an apparatus for carrying out the described method.

1. A method of positioning a piece of service equipment of a coal-charging larry cart at charging ports of a coke oven, the method comprising the steps of:
moving a rail-guided larry cart in one direction on the roof of a coke oven and positioning it at locations known by a machine control system and corresponding to charging ports in the oven roof in order to charge the oven chambers; thereafter positioning the piece of service equipment of the coal-charging larry cart to the respective charging port by horizontal positioning movements in the one direction and in another direction; after each positioning of the larry cart, optically determining the coordinates of at least one marking that is applied to the oven roof at an offset and at a fixed spacing from the center of the respective charging port within a measurement field that is predefined by the measurement method and comparing the optically determined coordinates with reference values that are stored for this marking in the machine control system; and determining bidirectional deviations between the determined coordinates and the coordinates stored in the machine control system while taking the reference values into account during the bidirectional positioning movement of the piece of service equipment.
