| 摘要 |
The invention relates to a length-variable connection of an intake pipe (8) with a dust channel (9) of a ventilation system in an underground section to a transfer or bridge conveyor (7), which is placed between a stationary duct line (10) and an advance working machine (1) and which is displaceably supported on an advancing mechanism or a frame. The connection comprises a spiral duct (12) suspended from a carrier cable (15). The carrier cable (15) is fixed between two bearing parts (14, 21) of the advancing mechanism or of the frame (13) and the advancing machine (1), said bearing parts being able to be displaced in the same direction, and is guided over at least two deflection rollers (17, 18). |
