Definitions

the present invention relates to a machine for descaling and rectifying the wave wear of railroad tracks.
the rails for railway tracks Due to the heat treatments to which they are subjected during their manufacture, the rails for railway tracks, on leaving the factory, are covered with a layer of scale.
This layer of carbon is an electrical insulator for low voltage currents used for signaling and the transfer of information to the trains in circulation, through the rails of the track.
this descaling has been carried out by switching from sight to sight, that is to say, without signaling and at low speed, several trains of passengers or goods.
the tremors of these trains are sufficient to fragment the layer of carbon and gradually eliminate it.
the descaling thus carried out can be considered satisfactory when three consecutive trains pass on the concerned track without any interruption of the continuity of the low voltage current being detected.
the object of the present invention is therefore to provide a machine which makes it possible to carry out descaling on the track at a walking rate compatible with that of the installation or renewal sites, which ensures this descaling over a width of at least 40 mm and which prevents injury to the rails.
the invention is constituted by a machine of the type comprising a main chassis overlapping the two rows of a railway track and able to move over this track, said machine being provided with a plurality of disc grinders articulated to this chassis so that the disc each wheel rests by its periphery on the rail at an angle to the horizontal direction of said rail, characterized in that each wheel is mounted fixed relative to an arm articulated to a support so as to freely debate about a perpendicular axis has the longitudinal direction of the track, in that said support is itself mounted in a secondary chassis pivoting about an axis parallel to the longitudinal direction of the track and in that this assembly is mounted in the main chassis by means allowing the ascent and descent of the assembly relative to the track.
the articulated arm support has a stop limiting the downward movement of the arm so that the machine can be placed in a position above the track in which the grinding wheels do not rest on the rails when the secondary chassis is in its highest position relative to the main chassis.
the discs of the grinding wheels are of the type comprising a peripheral edge curved upwards so as to allow the machine to go back and forth without risk of punching the rail.
each disc slices and breaks the layer of scale in splinters in a first attack position where the edge of the disc in combination with the articulation of the arm carrying the grinding wheel comes to life with a slight movement of weaving or picking, and, in a second trailing position, provides the abrasion action of the grinding wheel to finish the treated width.
the discs of the grinding wheel are semi-rigid, as they must be able to absorb the forces caused by the jerking without risking attacking the rail itself and injuring it.
the grinding wheels of the machine according to the invention are articulated with free movement, they rest by their own weight on the rail and can adapt to all vertical deformations without risking cutting the rail.
the invention provides a machine comprising, for each rail file, a set of two grinding groups arranged one behind the other, each group consisting of two grinding wheels arranged on the one behind the other with a transverse offset, the two groups of the same assembly also being transversely offset between them.
the transverse offsets between the grinding wheels of the same group and between two groups of the same set are such that the working width at each pass is between 20 and 30 mm and is preferably 25 mm.
connection between the main chassis and the secondary chassis is therefore considerably simplified since, to obtain a working width of 40 mm, it suffices to provide two positions for adjusting the transverse offset of the two chassis by providing a slight overlap of the strips. worked.
a machine according to the invention comprises a chassis 1 symbolized by a rectangle mounted on two axles 2 with wheels 3 of the kind able to circulate on rails, or treads.
At least one axle 2 is motorized by being driven by a engine 4, preferably an electric motor powered by a generator comprising an internal combustion engine, this generator not shown being mounted on the chassis 1 or on a separate carriage so as to be able to travel on the rails at a reduced distance from the machine according to the invention.
a generator comprising an internal combustion engine
all four wheels are motorized, for example by means of a chain transmission 5 and cooperating toothed wheels 6.
means, not shown, forming a displacement or speed sensor of the machine are provided and an appropriate control device, the operation of which will be described later, receives the signals representative of the displacement or of the speed of the machine. .
the chassis 1 is formed by assembling longitudinal members la and cross members constituted by metal profiles, not shown for clarity of the drawing.
ascent and descent means are constituted in this embodiment of the invention by a set of connecting rods 8 articulated on the chassis 1 by means of axes 9, and articulated on the secondary chassis 7a to 7d by means of axes 10 integral with the secondary chassis 7a to 7d.
the connecting rods 8 and articulations 9, 10 are designed and arranged, so that the movement of ascent or descent of a secondary chassis 7 corresponds to the deformation of a deformable parallelogram of vertices 9, 10, 9, 10: thus, each secondary chassis 7 remains continuously parallel to itself during the upward or downward movement and remains substantially parallel to the rail file above which it is located.
the up and down control is carried out using an actuating means, such as an electric jack 11 of the ball screw type (FIG. 4).
the secondary chassis 7a to 7d are designated below in the present description by the expression “cradle up and down” and they are identified by the reference 7.
each up and down cradle 7 is mounted a pendulum cradle 12 (12a to 12d) pivoting about a geometric axis 13 materialized by two ends of the shaft 14 and 15 mounted in bearings 16 and 17 or the like.
the geometrical axis 13 In order to orient each pendulum cradle 12 in order to be able to follow the contour of the section of the rail 14, provision is made for the geometrical axis 13 to be situated substantially in the vertical plane of symmetry of the rail file to be treated: it will therefore suffice to slightly tilt the pendulum cradles 12 at a certain angle to treat not only the upper table but also the upper fillets of the outline of the rail file.
each pendulum cradle 12 at least one machining module 20 adjustable in transverse movement is mounted inside the pendulum cradle 2 and preferably a pair of machining modules 20.
the machining modules 20 are pivotally mounted around axes 21 integral with the pendulum cradles 12, so as to pivot between two positions determined by high 22 and low 23 stops.
a spring or elastic means 24 is advantageously provided for applying the machining module 20 on the rail with a predetermined force when the module 20 is inclined at a significant angle with the vertical corresponding to the machining of the lateral leaves of the rail.
a machining module 20 comprises an arm or a receiving table 19 and an electric motor 25 for driving a grinding wheel 26 in the form of a curved disc.
This wheel is for example of a composition as described in the French patent application 90.12294 published under No. 2,667,607 in the name of the applicant Company.
the grinding wheel 26 is inclined relative to the rail and has an entirely convex shape, so as to press on the rail during machining with a pressing pressure of between 50 and 700 bars without nicking or injuring it ( Figures 4 and 5).
This pressing pressure corresponds during the machining of the horizontal table of the rail to the application of the weight of the machining module on the lever arm articulated at 21 on the pendulum cradle 12.
the weight of the machining module is between 100N and 200N.
the bearing pressure of the grinding wheel 25 resulting from the weight of the machining module decreases: to keep a constant bearing pressure, when machining the lateral leaves, we put while in service, the elastic support means constituted by the spring 24.
the reception table or reception arm 19 of the machining module 20 is mounted inside the up-and-down cradle 7 according to a Cardan assembly corresponding to the pivotings around the geometric axis 13 parallel to the rail to be machined and around axis 21 orthogonal to the rail to be machined or descaled.
the external width of the pendulum cradle 12 is less than the width of the up-and-down cradle 7, so as to allow complete rotation of the pendulum cradle 12 carrying the machining modules 20 inside the cradle and-drop 7: this arrangement allows the replacement of grinding wheels 26 without any disassembly of the machine according to the invention.
the machine according to the invention is moved in the direction of arrow 30 (FIGS. 4 and 5) which corresponds to the attack of the grinding wheels at an angle between 10 ° and 60 °.
the grinding wheels 26 cause during advancement a significant embrittlement and a rupture of the scale layer, similar to the effect of a picking.
this compliance effect is characteristic of the present invention.
the width of the strip worked by each grinding wheel corresponds to approximately 7 mm.
the first attack pass makes it possible to descale a rail strip greater than 25 mm.
This slow attack pass is followed by a finishing pass or rapid pass in the direction opposite to the arrow 30 (FIGS. 4 and 5): the grinding wheels 26 remaining inclined in the same position are then in the trailing position, which allows the machine to be driven at a speed between 2 and 5 km / h without any risk of injuring the rails.
the control device acts on the jacks 1 to lift the cradles up and down 7 so as to raise the grindstones 26 by means of the stops 23 and to avoid any chattering of the grinding wheels 26 on the rails and any injury thereof.
the invention also allows the machining and grinding of rails deformed by wave wear.
the machine preferably moves in the opposite direction to the arrow 30, so as to place the grinding wheels 26 in the trailing position.
the secondary chassis or lower-and-lower cradles are lowered into a position corresponding to the support of the high stops 22 on the reception tables 19 of the machining modules 20.
a control is thus obtained of the working depth of the grinding wheels 26, so that the working plane of the grinding wheels 26 remains constantly parallel to the bearing plane of the wheels 3 on the corresponding rails.
the amplitude of vertical displacement corresponding to the deformation of the parallelograms 9-10-9-10 under the action of the jacks 11, is of the order of 20 mm and the height adjustment precision of the order of one tenth of millimeter.
the machine according to the invention has a width of the order of 2m, a width of the order of 3m and a total weight of the order of 6,000 N: this size and this reduced weight allowing easy storage and handling constitute an additional advantage of the invention compared to heavy and bulky equipment of the prior art.
the invention described with reference to a particular embodiment is in no way limited thereto, but on the contrary covers any modification of structure and any variant of execution, in which the descaling or rectification wheels are mounted floating in two degrees of freedom in rotation and a degree of freedom in vertical translation, so as to be able to freely follow the contour of the rail during the considered treatment.
the invention also relates to a device and a method for cleaning the treads of railway tracks for urban transport on tires, similar to the aforementioned device and methods.
the grinding wheels are also mounted floating relative to the treads which they clean, the advantages of the present invention are fully transposable to the corresponding device and method.
