Definitions

  • the present invention relates to a portal for re--moving and laying railway tracks, particularly points.
  • the portal which' is the subject of the present invention is of the type having a crossbeam with ends which are vertically slidable along respective pillars.
  • This replacement operation should be carried out quickly so as to limit the consequences of interruption to the railway and, if possible, to prevent any shutdowns of the tracks adjacent that undergoing maintenance.
  • the track sections to be replaced are raised by means of portals which are movable on auxiliary rails located at the sides of the track undergoing maintenance. This procedure is particularly complicated and requires a large amount of time, as well as resulting in considerable interference with the running of trains on the tracks adjacent that undergoing maintenance.
  • the replacement operation is even lengthier and more difficult at present, and requires the use of a very large work force. Indeed, it is not possible to lay the auxiliary rails alongside the track section including the points, and the points must be raised from the ballast by batteries of jacks to such an extent as to allow the laying of auxiliary rails underneath them in alignment with the railway track and the insertion of a plurality of bogies between the points and the auxiliary rails, on which the points are then rested and by means of which they are carried away.
  • the problem behind the present invention is that of devising a portal of the type specified, which has structural and functional characteristics such as to satisfy the said requirement.
  • each of the pillars has its own means of individual advancement on the ground, for example, tracks or tyred wheels.
  • the crossbeam comprises a central section and end sections which can be withdrawn individually from the central section, the central section being provided with its own retractable support means.
  • a portal according to the invention is generally indicated 1.
  • the portal 1 is used for the removal and laying of sections of railway track, particularly points. The operation of the portal 1 will be described below with reference to the removal of worn points 2A and the laying of new points 2B to replace them along a railway line 3.
  • the portal 1 is of the type in which a horizontal crossbeam 4 has ends slidable vertically along respective lateral pillars, both indicated 5, under the action of respective vertical hydraulic cylinders, both indicated 6.
  • each pillar 5 has its own means 7 of advancement over the ground, such that they are self-propelled.
  • These means 7 each comprise a track 8 rotated by a respective hydraulic motor 9 which is connected to it by a chain transmission with chains 10, 11.
  • the tracks 8 are of such a length and width as to give the portal the stability necessary to allow it to move safely over the ground and, in particular, to allow it to move on the ballast, travelling safely over the sleepers and any rails which may be in its path.
  • the crossbeam 4 includes a central section 12 and end sections, each indicated 13.
  • Each of the end sections 13 can be extended individually from the central section 12, with which it is engaged telescopically, by means of a respective horizontal hydraulic cylinder 14.
  • the central section 12 of the crossbeam 4 is provided with its own retractable support means, generally indicated 15. More particularly, the retractable support means 15 comprise a railway bogie 16 on which the central section 12 of the crossbeam 4 is mounted with the interpositioning of a turntable 17.
  • the railway bogie 16 has wheels 18 mounted at the ends of legs 19 which are hinged to the bogie 16 and are angularly displaceable under the action of hydraulic cylinders 20 between a lowered operative position and a retracted withdrawn non-operative position.
  • a bolt 21 is located in correspondence with the turntable 17 to lock the central section 12 of the crossbeam 4 angularly relative to the bogie 16, either in alignment with the direction of advance of the bogie or perpendicularly thereto.
  • a seat 22 for an operator On the central section 12 of the crossbeam 4 is mounted a seat 22 for an operator, a first motor 23, to advantage a diesel engine, for driving a hydraulic pump 24 which supplies pressurised oil to the hydraulic cylinders, a control box 25 for the hydraulics, and a group of manually-operable directional valves 26 located in front of the seat 22 for use by the operator in controlling the hydraulic cylinders.
  • Rigid and flexible tubing known in itself and hence not shown connects the pump, the hydraulic cylinders, the hydraulic control box, and the directional valves.
  • Grippers 27 of a conventional self-closing type for gripping the heads of the rails are suspended by chains 28 from the central section 12 of the crossbeam 4.
  • the operation of the portal 1 is described below with reference to an initial moment (see Figure 3) when the portal 1, having been driven along the railway line 3, reaches the point where it is to be used.
  • the bogie 16 has its wheels lowered into engagement with the track
  • the crossbeam 4 is supported by the bogie 16 in alignment with the direction of the bogie itself and hence with the track
  • the pillars 5 are vertical and extend above the crossbeam 4 itself
  • the tracks are raised to a medium height and are non-operative.
  • the portal 1 lies completely within the clearance prescribed for trains and can therefore be moved freely along the railway.
  • the operator increases the width of the portal 1 by extending the end sections 13 of the crossbeam 4 from the central section 12 thereof by means of the horizontal cylinders 14.
  • the width of the track may be taken to be the maximum distance between the rails alone at the particular point, excluding the sleepers. Indeed, at the point where the portal is located, a limited number of sleepers (four or five) may have already been removed.
  • the operator effects a horizontal displacement of the central section 12 by reaction against the end sections 13 which are fixed relative to the ground by the pillars (see Figure 8).
  • the amount of the horizontal movement of the central section 12 is chosen to bring the grippers 27 into a position which is substantially centered relative to the track so that the track can be gripped efficiently.
  • the portal 1 acts in cooperation with other portals (see Figure 11) similar to the portal 1,which are distributed regularly along the points so as to ensure their safe and stable support.
  • the three portals 1 are, as described previously, brought astride the points 2A to be removed so as to be positioned at their ends and intermediately.
  • the points 2A are lifted and removed from their seatings by virtue of the combined action of the three portals, each of which is manoeuvred by a respective operator as described previously.
  • the points are carried to and placed on a service bogie 29 waiting on the line 3.
  • the three portals are then brought astride new points 2B which are resting on another service bogie 30 which is waiting on the line 3 on the opposite side from the bogie 29. Acting always in cooperation, the three portals lift the points 2B from the bogie 30 and carry them to the seating on the ballast where they are lowered.
  • the operators ensure the correct alignment of the points with the line 3 by moving the central sect--ions 12 of the respective portals appropriately.
  • each portal is brought back to its initial condition by repeating the operations described above with reference to Figures 3 to 10 in reverse.
  • a further advantage of the portal according to the invention lies in the fact that it allows a drastic reduction in the work force which is decreased substantially to the very small number of operators necessary to drive the portals used in the operation.
  • the portal according to the invention further allows a considerable improvement in the working conditions for the work force to be achieved from the point of view of accidents.
  • the tracks may be replaced by a series of tyred wheels.
