Definitions

  • the present invention relates to a device for removing iron-containing waste from a railway, comprising a vehicle which can be driven over rails of the railway, which vehicle has a number of endless parallel magnetic belt units, each unit composed of an endless conveyor belt guided and driven over guide rollers, magnets being placed at some points along each belt, which conveyor belts lie with a bottom end near the ballast of the railway and lie with the other end higher up above a collection container.
  • the invention relates to a device for removing grinding material residues lying in the form of pieces or lumps in the ballast of the railway.
  • Such grinding material residues are produced after grinding of the rail, and are still often removed by hand.
  • This removal by hand is a labour-intensive operation, which is carried out by persons walking along the rail track and picking up the lumps and throwing them into a container travelling over the tracks.
  • US Patent Specification US-A-2006/0045684 discloses a device for removing metal objects from a railway.
  • This device comprises a vehicle which can be driven over the tracks, which vehicle has a number of parallel adjacent endless magnetic belt units. These magnetic belts lie with their bottom end near the ballast of the railway and end with the top end above a collection container for the metal-containing objects.
  • the device has a lift mechanism, by means of which magnetic belt units can be raised slightly, so that the bottom end of the magnetic conveyor belts can be lifted up slightly from the working position. This lift serves to make the magnetic belts more accessible when said belts have to be replaced. Since this known device is confined to railways, it cannot quickly and easily be used in different places.
  • the object of the present invention then is to provide a device which can automatically and reliably pick up and remove metal objects and grinding material residues, which device can easily be employed on any desired stretch of railway.
  • the vehicle Owing to the fact that the vehicle is a rail/road vehicle, said vehicle can be placed on the rail at any railway crossing in order to reach a stretch of the railway to be cleaned.
  • said magnetic belt units By pulling the frame to which the magnetic belt units are connected onto the loading platform, said magnetic belt units are taken into the transport position on the loading platform. In this transport position the total length of the device is considerably reduced, so that the device is suitable for road transport. Furthermore, the metal-containing materials removed from the railway can be taken to a waste processing plant by the same vehicle.
  • each of the magnetic belt units is connected to the frame so as to be rotatable over some distance in a vertical plane, so that each unit can move from the working position, in which a belt part of the magnetic belt runs directly above the railway sleepers, to a non-working position, in which the abovementioned belt part is raised slightly.
  • This construction has the advantage that the device is easily able to pass over railway crossings and points and other infrastructural objects, while the frame remains in the working position, and the clearing process can proceed.
  • magnetic belt units disposed parallel to each other are present, which magnetic belt units are fixed on the frame so as to be movable in a direction crosswise to the direction of movement of the rail/road vehicle.
  • magnetic belts are fixed on the frame so as to be movable in a direction crosswise to the direction of movement of the rail/road vehicle.
  • the rail/road vehicle has an additional air compressor, which supplies two pairs of jet nozzles which, viewed in the direction of travel of the vehicle, are situated in front of the bottom parts of the magnetic belts, each pair of jet nozzles blowing air against the opposite sides of a rail.
  • the object of said jet nozzles is to blow adhering iron-containing material off the rails, so that this material is taken within the reach of the magnetic conveyor belt units.
  • This jet cleaning of the rails is particularly important for keeping the electric separation joints of the rails (ES joints) clean.
  • the device according to the invention is composed of a rail/road vehicle 1 which is know per se, of which only a rail wheel 2 and a road wheel 3 and the loading platform 4 are shown.
  • the vehicle is placed on a railway comprising tracks 5 with two rails 5a and 5b.
  • a frame 6 is connected to the loading platform of the rail/road vehicle, which frame bears four magnetic belt units 7a, 7b, 7c and 7d (see Figure 4 ), which magnetic belt units lie two by two on either side of each rail, and can therefore substantially cover the entire area between and beside the rails.
  • each magnetic belt unit is composed of an endless belt 8 made of a suitable synthetic material, which belt is guided over a number of guide rollers 9, 10, 11 and 12.
  • the guide wheels are disposed in such a way that a straight belt part 8' is formed near the bottom end of the belt between the guide wheels 10 and 11.
  • This belt part 8' is intended to move in its working position some distance above the ballast bed of the railway. In practice, this belt part runs directly above the upper side of the railway sleepers (not shown).
  • the belt 8 is driven in the direction of the arrow V, which means that the belt 8 moves over the belt part 8' in a direction opposite to the direction of travel of the vehicle 1.
  • the guide wheel 11 is also a magnetic wheel, while magnets 13' are placed along the top belt part of the belt 8 connected to said wheel, so that the iron-containing material is retained on the belt until said material has reached the upper side of the magnetic belt and falls into a collection container 14 provided here.
  • the frame 6 is composed of a flat box-shaped framework 15, having on the upper side a gantry 16 positioned at right angles to it and on the lower side two bearing legs 17, each bearing on the end a supporting wheel 18.
  • the supporting wheels 18 are in the form of a railway wheel and in the working position of the frame shown in Figures 1 and 3 each run over a rail 5a and 5b.
  • the device is also provided with an additional air compressor (not shown), which is connected by means of lines to two pairs of jet nozzles.
  • Each pair of jet nozzles is composed of two jet nozzles 22, 23, and 22', 23' respectively which, viewed in the direction of travel of the device, are situated in front of the belt parts 8' of the magnetic belts, on either side of the rail.
  • the jet nozzles in this way blow compressed air against the opposite sides of the rail concerned, with the result that adhering dirt and iron-containing material is cleaned off the rail. This material is blown off the rail, so that it comes within the reach of the magnetic belts.
  • each pair of jet nozzles is fixed to an extending arm 20, which on the end is provided with a railway wheel 21, which in the extended working position runs over the rail.
  • Said jet nozzles can, for example, also be connected to the magnetic belt units or to the frame 6.
  • Fig. 1 shows the device in its working position, which means that the rail/road vehicle is travelling with the railway wheels over the rails 5a and 5b, the frame 6 with the supporting wheels 18 is also running over the rails, and the magnetic belt units with their belt part 8' are running close to the ballast bed to be cleaned.
  • the magnetic belt units and the flat framework 15 of the frame 6 lie substantially in the same plane.
  • the magnetic belt units 7a - 7d must be raised slightly so that they do not come into contact with the level crossing plates.
  • each magnetic belt unit 7a - 7d is rotatably connected in a vertical plane to the frame 6 by means of a pivot pin 25.
  • each unit is provided with an upwardly projecting arm 26, which is connected by means of a hydraulic cylinder 27 to the gantry 16. Retracting the hydraulic cylinder makes it possible to rotate the magnetic belt unit about the pivot pin (25) relative to the frame 6, from the working position shown in Fig. 1 to the raised position of Fig. 2 .
  • the frame 6 stays in the working position here, the railway wheels 18 running on the rails.
  • the frame 6 with the magnetic belt units fitted on it can be pulled onto the loading platform of the rail/road vehicle.
  • the frame first performs a tilting movement, until the flat framework 15 is lying substantially horizontally, after which said frame is pulled by means of suitable guides onto the platform until it assumes the position shown in Figure 3 .
  • the collection container 14 is, of course, pushed forward first.
  • the magnetic belt units are fixed on the frame so as to be movable in the direction crosswise to the direction of travel of the vehicle. This means that these magnetic belt units can be moved closer up against each other in the conveyor belt, so that the total width of the device is reduced and meets the road transport requirements.
