Method and device for the suspension of an air duct system

摘要

The invention relates to a method and a device for the continuous suspension of an air duct system in a tunnel or underground. A suspension rope is continuously delivered from a rope magazine to the air duct running out of a duct magazine, which suspension rope is fastened above the advancing air duct system to the roof or to the inner support of the gallery to be ventilated, so that the air duct can be suspended on this rope if need be by means of hangers. To compensate for different heights between the top side of the air duct and the fastening points for the rope, the rope magazine can be vertically adjustable in the form of a rope pulley or a guide pulley or can be under spring tension directed upwards.
