VACUUM CLEANER TRAIN FOR CLEANING TRACKS, PARTICULARLY FOR UNDERGROUND RAILWAY NETWORKS

摘要

The present invention relates to a vacuum cleanertrain which comprises a blowing device mounted trans-versely and two suction devices disposed downstreamand upstream of the blowing device, as well as meansfor transversely adapting the blowing and suctionflows, adapted to effect a non-homogeneous distributionof said flows transversely with respect to the directionof the train.According to one version, the suction and blowingdevices comprise pipes partitioned into three compart-ments, three supple conduits for connection to thecorresponding fans and means for positioning the con-duits on one or the other compartment.According to another version, these devices com-prise nozzles equipped with obturation means and meansfor controlling the obturation means in synchronization.Moreover, the endpiece of the nozzles may be orientablelaterally for cleaning overhanging platforms.
