Definitions

  • The.invention relates to a device for regulating the substructure of ballast on railway tracks.
  • the digging is generally done with a continuous chain cutter that extends transversely to the track, is placed underneath the substructure of the sleepers, and conveys the metalling to the purposely provided riddles where the minute parts are separated from the utilizable metalling, while conveyor belts attend to the distribution of the screened metalling to underneath the sleepers, and to the ejection of the non-utilizable metalling.
  • each claw equipped chain is powered by drive means placed on the end of the bar.
  • the regulating bar is able to rotate around its own axis, transversely to the track, and to be locked at a suitable inclination with respect to the railway track on which the screened metalling is to be distributed, while each of the aforementioned support arms is able, through oil hydraulic mechanism, to lengthen until it has coupled with the said bar, and to shorten once the latter has been removed at the end of the operation.
  • the renewal of the railway ballast is achieved in the way that it is carefully screened, redintegrated and redistributed underneath the substructure of the sleepers.
  • the essential object of the invention is, therefore, to overcome the aforementioned difficulties in a way that complies with the safety and railway standards, through a device with which it is possible to regulate the substructure of the ballast, at the time the latter is being renewed and, contemporaneously, to achieve a degree of finish that is sufficiently high to permit rolling stock to transit, at a decent speed, over the said section of the track that has just been subjected to maintenance but which does not require additional follow-up apparatus since, using extremely simple methods, the machine utilizes the device in question for this purpose.
  • the device according to the invention coupled to a riddling machine provided with a main digging channel for removing the metalling from the ballast and conveying it to a screening/dist- ributing group for the realization of a fresh substructure of ballast, characterized by the fact that it comprises: an endless chain, equipped with a plurality of claws, this sliding partially in the inside of a guide channel that is placed, over a given distance, transversely to the rails, underneath the substructure of the sleepers and downstream of the said digging channel with respect to the movement direction of the machine, the said guide channel having, bilaterally and symmetrically with respect to the vertical plane defined longitudinally by the movement direction, two sections that slope on to a vertical plane and converge in a horizontal plane towards the axis of the machine, the said sections being provided, in the region of the verticality at the extremity of the sleepers, with an aperture for the discharge on to the latter of ,part of the metalling conveyed by the chain, the said device comprising,
  • the said conveyor is of a length at least equal to the gauge of the track and it slides with a movement direction that- is in harmony with the one followed by the chain.
  • the advantage the said device offers consists in the fact that the ballast is levelled and that the excess metalling is distributed on to the lateral extremities of the sleepers, thereby creating a renewed ballast over which rolling stock is able to pass at an adequate speed.
  • a riddling-levelling machine hauled by a locomotive that is not depicted in Figure 1 but is positioned to the extreme left thereof.
  • the machine has a frame (3), sustained at the rear by a bogie (4), that is provided with a digging channel (5) carrying a non-illustrated chain, the front section (5') of which extends transversely to the track, destined to remove the metalling from the ballast (M) to be renewed and to channel it above a non-illustrated conveyor belt which, in turn, takes it to a riddle.
  • the device in question placed downstream of the said channel (5) and of the said hopper (7), which comprises an endless chain (10), equipped with a plurality of claws (11) for laying hold of and conveying the metalling, so placed that it slides partially inside a guide channel (12) under the action of a motor (13).
  • the said guide channel has a horizontal section (20), placed transversely to the rails underneath the substructure (P) of the sleepers, of a width greater than the length of the latter, and at a height that is generally above that of the digging channel (5) but can be varied by a pair of hydraulic cylinders (14) fixed by the body to the frame of the machine, with the rod on the lateral sections of the guide chain.
  • each channel is provided with a metalling discharge trap-door (15), the area of which is less than that of the channel itself, wherein the extent of the opening can be varied by means of a shutter; the two channels meet in the region of their terminal part close to the vertex (V) and discharge the remainder of the metalling into an underneath hopper (16) whose lower part opens on to a horizontal conveyor belt (17) that extends transversely above the track and is of a length at least equal to the gauge of the railway.
  • the said conveyor belt (17) is movable in the two directions, operated by a motor (18), similarly to the chain (10).
  • the operation of the device forming the subject of the invention is very simple: placed at a level higher than that of the digging channel (5), it flattens the unevenness in the fresh ballast formed by the hopper upstream of the device itself.
  • the said unevenness is due to the metalling in the new ballast being distributed in a different fashion.
  • the dual object is achieved of levelling the ballast substructure and of anchoring the sleepers (this being indispensable, particularly on bends).
  • the first of the said blades namely the one numbered (22), extends in a virtually vertical plane parallel to the axis x-x and has the twin task of preventing the material carried by the chain from continuing to move transversely without being charged along the sloping guide (12') or (12") and of restraining the metalling on the adjacent bank (in cases when there is a double track), stopping it from sliding along the line where there is the most gradient, coming into contact with the chain and thus being carried along by this.
  • the second of the said blades namely the one numbered (23), has the task, differently from the first blade numbered (22) which can be closed or disengaged, of restraining the metalling laterally outside the area along which the channel (20) passes.
  • the device is symmetrical with respect to the longitudinal axis x-x since the chain (10) can rotate clockwise, and the conveyor belt (17), consequently, in the reverse direction thereto.
  • the invention can also adopt forms that differ from what has been described above and, in particular, numerous modifications of a practical nature may be made without in any way deviating from the framework of protection afforded to the invention.
