Definitions

  • the present invention relates to an assembly comprising a rail and a press for rails constituting a running and guiding track of a railway vehicle.
  • a railway track which constitutes a running and guiding track for railway vehicles, typically comprises two rails arranged and fixed on sleepers and maintained at a constant spacing.
  • the railway track rests on ballast to support the sleepers, but also to distribute the loads on the ground.
  • the repeated passage of rail vehicles on these tracks requires regular maintenance of the rails.
  • Each rail comprises a succession of adjacent rail sections, placed end to end, and fixed two by two. They can therefore be welded together.
  • Press 1 illustrated on the figure 1 comprises a frame 3 on which two hooks 4, or C-shaped parts in the example illustrated, and an actuator 5 are movably mounted.
  • An actuator 5 is a device which transforms the energy supplied to it into a physical phenomenon which provides work, modifies the behavior or the state of a system.
  • a pneumatic or hydraulic cylinder generates a movement from mechanical energy transmitted by a gaseous or liquid fluid.
  • a hook 4 is an example of a hooking device, in the sense that it comes here under an element, such as a rail 2, to, once thus engaged under it, lock there if we pull on it transversely (along F) to the direction (E) of engagement of its hooked edge.
  • Press 1 illustrated on the figure 1 allows you to press a rail 2 only downwards, in the state in which it is found.
  • the two hooks 4 make it possible to maintain the position of the rail 2 relative to the press 1. They are arranged partly under the rail 2.
  • the actuator 5 exerts a force F on the rail 2, towards the ground on which the sleepers and the rail 2 are arranged.
  • the two hooks 4 are then, more precisely, placed under the shoe 6 of the rail 2, which shoe 6 serves to apply the rail 2 in a stable manner to the sleepers.
  • Each rail 2 comprises, in addition to a lower shoe 6, flared downwards in section, a thinner intermediate core 7 and an upper mushroom 8 flared in section upwards. Rail vehicles run on mushrooms 8 of rails 2.
  • Pressing downward with a press therefore typically requires that the hooks 4 (or more generally the hooking device) be placed under the shoe 6 of the rail 2. Arranging these elements under a rail 2 in the middle of the track can be made difficult by the presence of the ballast for example, but also of the sleepers 9 and the elements for fixing the rails on the sleepers. Furthermore, such a press 1 only allows downward pressing, and cannot be use to correct a downward deformation of a rail 2 (requiring upward pressing). For upward pressing, you must turn the press over and change its tools.
  • the aim of the invention is to propose an alternative press, usable on track, allowing the pressing of a rail upwards and/or downwards and allowing optimized positioning of the press and pressing points on the rail in relation to to the deformation of the rail upwards or downwards. It is also intended to avoid lifting the rail to pass the press tool under the rail when the lifting point is located above a sleeper, therefore not accessible.
  • Such a press makes it possible to correct a deformation of the rail which may be upwards or downwards. Indeed, with a hooking device and a minimum actuator, the press exerts a torque on the rail so as to reduce the deformation of the rail.
  • the proposed press does not require access under the rail to exert force on the rail, in order to reduce deformation.
  • the hooking device is adapted, when it is in the engaged state, to hold the rail at the level of the head and not under the shoe. With such a picking device, we can press the rail and act at the level of the deformation and not nearby, as in the state of the art, when access was limited.
  • said at least one hooking device is mounted freely tilting relative to the chassis around the second axis.
  • the tilting hooking device(s) i.e. pivoting around the second axis
  • the inclination of the hooking devices adapts to the inclination of the rail.
  • the free inclination of the hooking devices makes it possible to avoid impacting the rail which would ultimately cause breakage or fatigue defects.
  • said at least one picking device comprises a pair of jaws.
  • the jaws will hook the rail, on both sides of the rail, along the second axis. This is a guarantee of balance and efficiency. The positioning engaged is then very stable.
  • the press comprises several said actuators and the jaws of said pair of jaws can be mounted movable in translation on the chassis along the second axis and can be controlled by the control unit capable of coordinating the mobility of the pairs of jaws and the actuators .
  • the control unit will thus make it possible to synchronize the actions of the pairs of jaws and the actuators on the rail, so as to exert the force desired by the operator to correct the deformation of a rail.
  • said at least one picking device may successively comprise a first, a second and a third picking device and said at least one actuator may successively comprise a first and a second actuator , said picking devices and said actuators being arranged along the first axis so that the second picking device and the second actuator are disposed between the first and third picking devices.
  • a change in pressing direction does not then require changing elements of the press: the hooking devices as well as the actuators are controlled by a control unit and each of them is activated depending on the direction of pressing of the desired rail by the operator.
  • the press is even more versatile, without complications.
  • the distances separating along the first axis respectively the first hooking device and the first actuator and the second hooking device and the second actuator may be less than the distances separating the actuators between them and at the distances separating the picking devices from each other.
  • said second picking device and said second actuator can be arranged substantially halfway between said first and third picking devices.
  • said at least one press actuator may further comprise a third actuator, so that the second hooking device is disposed between the first and third actuators.
  • Such a configuration of the press thus makes it possible to balance the forces applied by the actuators, and therefore to press the area of the rail, presenting the deformation upwards or downwards, uniformly.
  • said at least one hooking device may comprise an interior rim having an upper bearing surface for support on it from below the head of the rail.
  • the hooking devices having such a rim then ensures retention of the rail at the level of the core, under the head.
  • Such hooking devices therefore do not require access under the rail presenting a deformation, and can thus be used even near a sleeper for example.
  • said rim may include a groove along the third axis.
  • Such a groove may prove necessary when pressing is carried out at a weld.
  • only the weld surface of the head is ground, so there is a weld bead under the head, along the core.
  • the groove sized so as to be adapted to any weld bead, makes it possible to optimize the contact of the hooking devices, particularly when the pairs of jaws are closed around the head of the rail.
  • the groove can be through and central, in the rim.
  • the rim may also include a free (upper) wall, rounded convex.
  • the rail 2 a cross section of which at its longitudinal axis 11 is visible on the Figure 5 , comprises a pad 6, a core 7 and a mushroom 8 connecting the mushroom 8 to the pad 6.
  • the mushroom 8 is the upper part of the rail 2 on which the wheels of the railway vehicle rest.
  • the shoe 6 is the lower part of the rail 2 which rests on sleepers which are pieces placed across the track making it possible to maintain the inclination and spacing of the rails 2.
  • a press 1 as presented aims to reduce deformation of such a rail 2, either upwards or downwards. These deformations are illustrated on the figures 3 and 4 .
  • An upward deformation is characterized by the appearance of a convex zone 14, convex upwards, the highest point 15 of which tends to move away from the ground. This type of deformation is likely to appear at the junction of two portions of rail 2.
  • a downward deformation is characterized by the appearance of a hollowed out zone 16 towards the bottom, the lower point 17 of which tends to approach the ground. This type of deformation can appear both in the full portion of rail 2, and at the level of a junction of successive portions of rail 2.
  • the press 1, usable in full track, comprises a chassis 3.
  • the chassis 3 is elongated along the first axis 11, also called elongation axis.
  • At least one hooking device 18 of the rail 2 is mounted on this chassis 3.
  • picking device a device capable of occupying an engaged state under an upper part 8 of the rail 2 along the second transverse axis 12 to the first axis 11 , so as to be caught under this part in the manner of a hook 4 or an L-shaped tab.
  • the hooking device 18 is adapted, in the engaged state, to hook the rail 2 at the level of soul 7, just under mushroom 8.
  • Press 1 illustrated on the figure 2 comprises a hooking device 18 comprising a first, a second and a third pair of jaws 20a, 20b, 20c adapted so that in the engaged state, the jaws 20 hook the rail 2, on either side of the rail 2, along the second axis 12.
  • a hooking device 18, with a only pair of jaws 20, or even just one of the two hooks 4 like those of the figure 1 could have been expected.
  • FIG. 5C An example of a pair of jaws 20, in the respectively engaged states ( Figure 5C ) and not engaged ( Figure 5B ) is illustrated on the Figure 5 .
  • the jaws 20 extend along the third axis 13 transverse to the first and second axes 11, 12.
  • the jaws 20 are arranged on either side of the first axis 11, preferably facing from each other for a better balance of forces.
  • the jaws 20 of the example of press 1 illustrated each have a general L shape: at one of their ends, the jaws 20 each comprise a lower inner rim 21a which extends transversely projecting along the second axis 12 by relative to the lateral upright 21b of the jaw which extends vertically, along the third axis 13.
  • This rim 21 has a shape adapted to be placed at the level of the core 7 under the mushroom 8.
  • the rim 21 comprises an upper free wall 22 coming into contact with the lower part 8a1, 8a2 of the mushroom 8, at the top of the core 7.
  • the pairs of jaws 20, in particular the first and third pairs of jaws 20a, 20c, can have a rim 21 with a rectilinear upper free wall 22.
  • the rim 21 of the second pair of jaws 20b can have an upper free wall 23 which will on the other hand be rounded, convex upwards, as illustrated in the Figure 7B .
  • Such a wall 23 proves particularly interesting when pressed upwards. Indeed, the shape thus rounded makes it possible to bring the contact points 24 of the edges 21 of the jaws 20 of the second pair of jaws 20b closer together on the rail 2, as illustrated in the figure 8 .
  • the contact points 24 of the rim 21 on the rail 2 when pressed upwards, are brought together. By bringing together these contact points 24, the shear stresses in the rail 2 when it is pressed upwards are, at the same time, reduced.
  • the pairs of jaws 20, in particular the second pair of jaws 20b may comprise a groove 25, centered, extending along the third axis 13.
  • This groove 25, passing through the free rim 21, ensures good closure of the pair of jaws 20 on the rail 2, despite the presence of a weld bead 26, when the pressing is carried out at a welded junction 27 between two successive portions of rail 2.
  • a weld bead 26 is generally ground. Under the mushroom 8, the weld is not ground, the weld bead 26 is therefore present which can hinder the closing of the jaws 20 on the rail 2.
  • This weld bead 26 has an extra thickness generally of the order of 2 mm relative to the rail.
  • the groove 25 provided may therefore have a width, along the first axis 11, of between 3 and 10 mm.
  • the pairs of jaws 20, making up the hooking devices 18, are movably mounted on the chassis 3, and arranged successively along the first axis 11.
  • each of the jaws 20 is tiltably mounted on the chassis 3, around the second axis 12.
  • Such an assembly allows the jaws 20 to have a pendulum movement 28, around the second axis 12, allowing them to follow the movement of the rail 2, in particular during downward pressing, in order to maintain contact linear under the rail head.
  • the capacity of the jaws 20 to be able to tilt allows each of the pairs of jaws 20 to be naturally centered under the mushroom 8 at the level of the core 7 of the rail 2.
  • each of the jaws 20 is mounted on the frame 3 movable in translation along the same second axis 12. More particularly, the pairs of jaws 20 are mounted movable in translation along a shaft 34 of the frame 3 s 'extending in a direction along the second axis 12. The pairs of jaws 20 are thus capable of easily reach their two states, engaged and not engaged, visible figure 5 .
  • the engaged state of the pairs of jaws 20 is adapted to avoid a movement of the rail 2 with respect to the press 1 downwards, that is to say along the third axis 13, towards the ground.
  • the jaws 20 could be movable in rotation along the first axis 11 or along the axis 13, to go from the unengaged state to the engaged state, and vice versa.
  • the stop 35 extends along the second axis 12, projecting relative to the rim 21 of the jaw 20.
  • Two coaxial stops 35 are intended to come into transverse support against each other when the pair of jaws 20 pass from the unengaged state to the engaged state. The presence of such stops 35 makes it possible to avoid excessive pressure on the core 7 of the rail 2 when the pair of jaws 20 passes to the engaged state.
  • a space, along the third axis 13, can be delimited between the upper end 8b of the head of the rail 2 and a lower end 36 of each of the stops 35.
  • the lower end 36 can be formed by a substantially flat wall extending in a plane formed by the first and second axes 11, 12.
  • At least one actuator 5 is adapted to act on the rail 2 in order to apply a force F oriented along said third axis 13 transverse to said first and second axes 11, 12.
  • this said “at least one” actuator 5 comprises a first, a second and a third actuators 5a, 5b, 5c, mounted successively on the chassis 3 of the press 1, along the first axis 11.
  • actuators 5 which can be pneumatic or hydraulic cylinders, are adapted to exert a force F on the rail 2 oriented along the third axis 13.
  • the actuators 5 are mounted so as to be able to exert a force F with the press 1 blocked on the rail 2 by its hooking device(s) 18, here at least one said pair of jaws 20.
  • the distance L1 is equal to the distance L2.
  • the distance L1 or L2 can be between 50 cm and 60 cm.
  • the distance between the first or third actuator 5a, 5c and the second hooking device 18b, respectively the distance between the first or third hooking device 18a, 18c and the second actuator 5b is between 40 cm and 75 cm.
  • the mounting of the pairs of jaws 20 and the actuators 5 on the frame 3 of the press 1 can be done so that the distances respectively separating the first hooking device 18a and the first actuator 5a, the second hooking device 18b and the second actuator 5b and the third hooking device 18c and the third actuator 5c are less than the distances separating the actuators 5 from each other and the hooking devices 18 from each other.
  • the first, second and third pair of jaws 20b, 20c are then respectively contiguous to the first, second and third actuators 5a, 5b, 5c.
  • the first pair of jaws 20a and the first actuator 5a are mounted on the chassis 3 close to each other. They can be a few centimeters or ten centimeters apart.
  • This assembly makes it possible in particular to have a compact press suitable for pressing upwards or downwards, with a single press.
  • the press 1 makes it possible to correct defects in a rail 2 presenting a vertical deformation either upwards (as visible on the Figure 3 ), or downwards (as visible as the Figure 4 ) according to third axis 13.
  • the deformations are deformations along the third axis 13, which are in the cases illustrated, at the level of the junction 27 by welding two portions of rail 2, creating a zone raised upwards ( Figure 3 ) otherwise called convex zone 14, or recessed downwards ( Figure 4 ) otherwise called dug area 16.
  • the upward or downward deformation can be quantified by an angle 30 of deformation formed between the level of the ground on which the rails 2 are placed and a deformed zone 14, 16 of the rail 2, the angle having as its apex either the highest point 15 or the lower point 17 of the deformation.
  • This angle 30 of deformation is indicated respectively on the figures 3 and 4 representing upward and downward deformations respectively.
  • the angle 30 of deformation is formed by one of the welded rail portions 2, and the axis 31 passing through the highest point 15 and extending parallel to the first axis 11.
  • the angle 30 of deformation is formed by one of the welded rail portions 2, and the axis 32 here representing the ground level, extending parallel to the first axis 11.
  • the latter preferably comprises a control unit 33 .
  • the control unit 33 will then make it possible to exert a force F on the rail 2 via the retractable mobile part 29 of the actuator 5, and to control the pairs of jaws 20 so that they are positioned at the engaged state.
  • the control unit 33 can for example be an automaton, comprising a user interface. By this means, operators can indicate to the automaton the type of pressing desired, upwards or downwards, as well as the force F to be exerted to reduce the deformation to at least a minimum accepted by the European standard NF EN 14587 -1 & 2.
  • the automaton 33 can also be coupled to one or more sensors 41 (lasers, magnetics or ultrasounds for example), capable of monitoring the deformation of the rail.

  • the sensors are positioned approximately 10 cm from the locking devices 18 or the actuators 5 concerned.
  • THE first and third sensors 41a, 41c are not necessarily placed 50 cm on either side of the weld, which is the measurement basis of the European standard NF EN 14587-1 & 2 for welds (typically at 50 cm of the second actuator 5b or hooking device 18b requested), the measurements provided by the sensors could need to be extrapolated so as to have an indication and sufficient precision for the operator to be able to quantify his successive pressing operations.
