Definitions

  • the present invention relates to a vacuum cleaner train for cleaning tracks, in particular for metropolitan networks. It relates more particularly to a vacuum train comprising a suction and blowing hood, covering the cleaning area, and equipped on the one hand with a high speed air blowing device intended to take off the dust and waste from the surface to be cleaned and arranged transversely to the direction of travel of the train, and on the other hand of two suction devices arranged respectively one upstream and the other downstream of the blowing device and intended to capture the dust and waste raised by the blowing device.
  • a suction train of this type is known in particular from document FR-A-2 074 564.
  • the suction or suction devices are equipped with flexible deflectors, profiled in the form of convergent-divergent; this particular embodiment aims to improve the capture of dust and waste by the suction cups by avoiding a sudden dispersion of this dust and this waste under the action of the blowing ramp, outside the suction action zone and blowing.
  • the aim set by the applicant is to provide an improved vacuum cleaner train which overcomes the aforementioned drawbacks in that it allows optimal cleaning of all track configurations and in that it can be suitable for small and medium networks. .
  • the vacuum train of the invention is a vacuum train with blowing and suction hood which in a manner known by document FR.A.2.074.564 comprises a blowing device mounted transversely and two suction devices arranged for one in downstream and for the other upstream of the blowing device.
  • the hood has several blowing and suction zones; in addition, the suction train of the invention comprises means for transverse adaptation of the blowing and suction flows, capable of selecting and channeling said flows towards the minus a predetermined area.
  • transverse adaptation means it is possible to concentrate the blowing and suction flows on a particular area of the track and consequently to obtain perfect cleaning of this particular area.
  • the blowing and suction hood comprising a blowing ramp connected to a blowing fan and two suction ramps arranged respectively downstream and upstream of the ramp blowing, and each connected to a suction fan, said ramps are partitioned into three independent compartments, transversely delimiting three working zones;
  • the hood comprises three flexible ducts for connection to the three blowing and suction fans and it also comprises means for positioning said ducts, capable of placing the three ducts in the position of connection with a given compartment.
  • the transverse suction means of the blowing and suction flows consist of the positioning means capable of carrying out the displacement and the synchronous connection of the three connecting conduits with one of the compartments of the blowing ramps and suction.
  • This first version of the vacuum train is also suitable for cleaning tracks that have a central pit, located between the rails, in particular the anti-suicide pits located in the stations.
  • the three connection conduits are positioned on the central compartment of the supply and suction booms.
  • the blowing and suction hood comprises a set of blowing nozzles juxtaposed transversely and two sets of suction nozzles arranged upstream and downstream of the blowing nozzles, and each nozzle is equipped with sealing means.
  • the suction train comprises control means able to control in synchronization the means for closing off certain blowing and suction nozzles so as to channel the blowing and suction flows towards a given zone.
  • the transverse adaptation of the blowing and suction flows consists of the means for shutting off the blowing and suction nozzles as well as in the means for controlling these shutter means.
  • the suction train of the invention comprises means for transverse deflection of the blowing and suction flows.
  • transverse deflection means The purpose of these transverse deflection means is to direct the blowing and suction flows towards the outside of the hood overlap zone and to allow good cleaning of the track beyond the rails. Particularly in the case of a track which is overhung by a platform nose, the transverse deflection of the blowing flow makes it possible to create a swirling movement of the air in the cavity located under the platform nose. This swirling movement makes it possible to raise the dust and waste located in this cavity normally not accessible by the suction train. The deflection of the suction flows makes it possible to collect the dust and the waste carried in this vortex movement.
  • the means for transverse deflection of the flows may consist of deflectors, mounted at the end of the side blowing and suction nozzles and directed obliquely towards the outside of the hood.
  • These can be deflectors which are fixedly mounted on the sides of the hood.
  • the corresponding nozzle comprising a flexible conduit
  • the deflector is orientable by rotation about a horizontal and longitudinal axis
  • the suction train comprises means for controlling the deflectors in rotation.
  • the driver of the suction train can control, without stopping the latter, the transverse deviation of the blowing and suction flows when he enters a station which includes platform noses.
  • the suction train of the invention comprises a set of four blowing nozzles arranged transversely, two central nozzles and two lateral nozzles framing the two central nozzles, as well as two sets of six suction nozzles, one set being located upstream and the other downstream of the set of blowing nozzles; moreover in each set of suction nozzles, four are exactly opposite the four blowing nozzles and two are beyond these first four arranged opposite the side nozzles; the extreme lateral suction nozzles are provided with movable deflectors in rotation, while the two intermediate lateral suction nozzles are provided with fixed deflectors.
  • the suction train also includes sealing flaps, extending laterally the blowing and suction hood and arranged so as to form with the edge of the platform a box, arranged on the side of the train and substantially waterproof.
  • the sealing flaps consist, for example, of a horizontal flap extending over the entire length of the hood, terminated at its ends by two vertical flaps, said flaps being fixed cantilevered on the frame of the hood.
  • a vacuum train is a train on which are mounted all the equipment necessary for cleaning the track by suction.
  • a vacuum train carries a blowing installation, a suction installation and a filtration and collection facility for dust and residual waste.
  • FIG. 5 shows a partial view of the blowing and suction installations which are mounted on the frame 1 of the train.
  • the blowing installation comprises a fan not shown in FIG. 5 which propels the air at high speed into a manifold 2, giving either in a blowing ramp arranged transversely with respect to the direction of travel of the train, or in different nozzles blowing 4 juxtaposed to each other along a transverse axis relative to the movement of the train.
  • the suction installation preferably comprises two fans, each one being connected either to a suction manifold arranged upstream or downstream of the blowing manifold, or to juxtaposed suction nozzles to each other transversely opposite the blowing nozzles.
  • the high speed air jet blown by the blowing ramp or the blowing nozzles is used to remove the waste and dust which are on the ballast to allow the suction by the boom or the suction nozzles arranged at immediate proximity to the boom or blowing nozzles.
  • blowing and suction ramps or nozzles constitute the blowing and suction hood 5 which overhangs the track to be cleaned.
  • blowing and suction ramps are partitioned into three juxtaposed compartments, a central compartment 6 and two lateral compartments 7 and 8, as clearly shown in Figure 1.
  • Each of these compartments 6, 7, 8 is fixed and overhangs a precise longitudinal zone of the track 9.
  • the lateral compartments 7, 8 have slightly flared end edges 10, 11 so that the lower part of the corresponding compartment is close walls 12, 13 surrounding track 9.
  • Each of the compartments 6, 7 and 8 has in its upper part an opening 14, 15, 16.
  • a flexible duct 17, terminated by a blocking end piece 18, makes it possible to ensure the connection of one of the compartments with either the supply manifold if it is a compartment of the supply manifold, or with the suction fan in the case of a suction ramp compartment.
  • a slide 19 in which the end piece 18 for blocking the flexible conduit 17 can slide.
  • the end piece 18 is integral with two sets of jacks, a first set of jacks horizontal axis making it possible to move the end piece in the slide 19 and a second set of jacks having a vertical axis making it possible to block the end piece on the slide when the free end 20 of the conduit 17 is found placed opposite one of the openings 14, 15, 16.
  • the suction train according to this first version also includes an automatic system for controlling the cylinders of horizontal and vertical axes allowing the train driver to select the compartments which will be operational, namely the central compartment 6, the lateral compartment 7 on the left on Figure 1, the right side compartment 8 in Figure 1.
  • the automatic control system makes it possible to synchronize the positioning of the three flexible conduits 17, corresponding to the three compartments aligned in the longitudinal direction, namely the central blowing compartment and the two suction compartments arranged upstream and downstream of this blowing compartment.
  • the suction and blowing powers are reduced in proportion and the dimensions of the suction and blowing fans are also reduced, whereby the suction train according to this first version is small and of lower cost and is perfectly suited for small and medium-sized networks.
  • FIG. 2 there is shown schematically the arrangement of these nozzles, namely a set 21 of four blowing nozzles 22, 23, 24 and 25 respectively from left to right in Figure 2, the set 21 corresponding to an alignment of the four nozzles 22 to 25 transversely to the direction of travel of the train, and two sets 59 and 60 of six suction nozzles.
