Definitions

  • the subject of the present invention is a machine for tamping railway tracks, in particular a machine for tamping, leveling and straightening railway tracks, comprising at least one movable tamping aggregate relative to the chassis of the machine, provided with at least a pair of picks suspended from a frame of the tamping unit, adjustable in height with respect to this frame and articulated to execute movements of approach and spacing relative to each other on either side a cross member of the track, and a mechanism for driving these pickaxes, and means for causing the tamping aggregate to move relative to the chassis in such a way that when the machine progresses at a uniform speed , the stuffing operations can be executed step by step, from cross to cross, respectively from group of cross to group of cross.
  • German patent application DE-A-1 067 837 illustrates this state of the art perfectly.
  • the packing aggregate moves on guide rails in a reciprocating movement, by means of a motor, via a cable, pulleys and a clutch.
  • German patent application DE-A-1 928 619 describes a machine for both compacting the battast between the sleepers by means of a tamper-compactor unit which acts on the ballast between two sleepers and simultaneously tamping the ballast by means of a tamping tool with a single pick which acts on the outside of one of the sleepers between which the ballast is compacted.
  • the tamping aggregate with a single pick is suspended from a transverse axis in order to allow the execution of the closing movement, therefore the movement necessary for the tamping itself.
  • This machine is stopped during the tamping and compaction operation and there is therefore the disadvantage of conventional machines moving step by step.
  • the object of the invention is to simplify such machines, both with regard to the adjustment and control of the tamping aggregate and with regard to its construction.
  • the tamping machine is characterized in that the frame of the tamping aggregate is suspended pendulumly to the chassis of the machine, around a transverse axis, the movement of the tamping aggregate during the progression of the machine at a uniform speed, being a pendulum movement.
  • the packing aggregate can thus move like a pendulum in a vertical plane and relative to the chassis of the machine.
  • This arrangement has several advantages.
  • the exact rapid adjustment of the packing aggregate relative to the chassis of the machine by tilting this aggregate around a fixed axis relative to the chassis is substantially simpler to carry out than a displacement in translation of this aggregate on guide rails.
  • the friction of rotation around an axis can be kept much lower than the friction of a rolling aggregate on guide rails.
  • the acceleration and braking forces are much lower than the forces required to move the whole aggregate in a linear back-and-forth motion.
  • the size of the tamping aggregate in the upper part of the machine is substantially smaller, since it is not necessary to provide space for the translational drive of this aggregate.
  • the tamping tools are mounted on a support and this support is movable vertically on a frame itself mounted pendulumally on the chassis.
  • Two columns can advantageously be fixed to the frame for guiding the support during the vertical displacement of the latter, these columns being provided with guide rollers at their lower ends, which roll on the rails.
  • This ensures permanent guidance of the tamping aggregate, guidance which can be further facilitated by suspending its frame by means of a universal joint, which allows the latter to also move transversely relative to the machine, so that the frame with its packing aggregate can freely follow the movement of the guide rollers on the rails.
  • the control of the tilting of the frame with the tamping aggregate is advantageously carried out by means of a jack attached on the one hand to the chassis and on the other hand to one of the columns.
  • the device is advantageously automatically controlled, so that the uniform progression of the machine corresponding to the average working speed is controlled as a function of the minimum duration of a tamping cycle, or, which amounts to the same thing, as a function of the distance between two consecutive sleepers measured using a sleeper detector.
  • the roller clamps 8 are controlled automatically on the basis of measurements carried out by means of a reference system, respectively a measurement base, which is defined by reference points of the channel and delivers a reference quantity.
  • a reference point A on the not yet corrected part of the track and, in the case of a straight line as the basis of measurement, a reference point C in the corrected part of the way.
  • the reference points A and C are defined by means of measuring wheels 9 and 10 mounted on the chassis 2 of the machine and rolling on the rails 5.
  • Another measuring point in the corrected part of the track can be defined by means of a mobile crew attached behind the machine. Near the working place, a measuring point B is also defined, by means of a measuring wheel 11, which defines the shape of the rail immediately behind the leveling and straightening tools. The measured quantities are compared with the target quantity to control the roller clamps 8.
  • the tamping aggregate 12 and its suspension are shown in more detail in Figure 2.
  • This packing aggregate 12 has on each side of a track 5, a pair of tamping tools 14 adjustable relative to each other and provided with picks 16 sinking into the ballast on each side of a cross member 15.
  • the tamping tools 14 of the two pairs are articulated to an eccentric shaft common 18 rotating in a support 17, the tamping tools 14 of each pair being constituted by levers with two arms which cross around the eccentric shaft 18.
  • the support 17 is suspended from a frame 20 on which it is vertically movable by means of a hydraulic cylinder 19, the frame 20, as well as the upper end of the hydraulic cylinder 19, being capable of tilting around the transverse axis 13 perpendicular to the longitudinal direction of the track, in the direction of the double arrow, in a vertical plane.
  • the frame 20 has a cross member 21 to which the hydraulic cylinder 19 is fixed, while the support 17 is fixed to the lower end of the piston rod 23 of the cylinder 19.
  • each column 24 and 25 oriented parallel to the piston rod 23 and which are fixed to the cross member 21 of the frame 20.
  • the lower ends of these columns are provided with guide rollers 26 and 27 rolling on the rail 5 and whose yokes can slide axially on the columns 24 and 25, during the tilting of the frame 20, by compressing springs.
  • the support 17 slides on the column 24 by means of a guide sleeve 28, while on the other side it has a guide profile 29 which can slide on a conjugate profile 30 of the column 25.
  • the upper ends opposite the picks 16, tamping tools 14 of each pair of tamping tools, are connected to the joints 31 with the lower ends of two double-acting hydraulic cylinders 32, the upper ends of which are articulated at the points of joints 33 within a range 37 of the support 17.
  • By actuating the hydraulic cylinder 32 it is possible to move apart or bring one closer to the other the tamping tools 14 in a pair.
  • the tamping tools 14 are pivoted on eccentric surfaces, so that the rotation of the shaft 18 has the effect of driving the picks 16 in an oscillating movement.
  • a hydraulic cylinder 34 articulated on the one hand at a point 35 to the frame 2 and on the other hand at a point. 36 to column 25 and the piston rod of which, during its extension, causes the tilting assembly to tilt with the packing aggregate 12 around the axis 13, in the position shown, partially, in phantom in the figure 2, the guide rollers 26 and 27 rolling on the rail 5 during this tilting.
  • the tamping aggregate 12 with its tamping tools 14 is raised above the level of the rails 5 by means of the jack 19.
  • the transverse axis 13 is not mounted directly on the chassis but on a shaft 40 mounted longitudinally on the machine between two bearings 41. In this way the frame 20 with the tamping aggregate 12 can oscillate in a plane transverse to the track and freely follow the movement of the guide rollers 26 and 27 on the rails, and thus center and adjust itself laterally.
  • the transverse shaft 13 could in principle also be fixed directly to the chassis 2.
  • the control and adjustment system installed for this purpose on the machine 1 essentially comprises, according to FIG. 3, a sleeper detector 50 constituted for example by an electromagnetic proximity detector reacting to the metal fixing of the rail, a device for measurement of the speed and of the distance traveled 51 constituted by a pulse counter which measures the pulses generated by a pulse generator 52 mounted on a wheel axle, respectively the frequency of these pulses, an electronic memory 53, a comparison 54, an adjustment device 55 and an adjustment member 56, for example hydraulic, by means of which the speed of advance v of the machine is adjusted.
  • the measuring members 50 and 51 deliver values for measuring the distance between two consecutive sleepers, these values being temporarily stored in memory 53.
  • the reference magnitude is deduced at all times from the speed of progression for which the time interval, during which the machine moves the distance of two sleepers, corresponds to the duration of a tamping cycle.
  • Temporary storage of the quantity measured in memory 53 is necessary, because the sleeper detector 50 is placed in front of the jamming aggregate 12, the control signal, calculated on the basis of the measurement, not to be applied to the tamping aggregate 12, only when the tamping tools have reached the place where the measurement was made, that is to say the crosspiece 15 to be tamped.
  • the setpoint quantity and the measured quantity of the speed of advance of the machine are compared in comparator 54 and the difference delivered by this comparator controls the adjusting member 56 through the adjusting device 55, and thereby the speed of advance of the machine.
  • the memory 53 also receives, at each end of a tamping cycle, a signal generated by a detector 57 signaling the end of the cycle.
  • a cycle is defined for example by the space of time between two consecutive elevations of the packing aggregate 12, that is to say between the instant at which the aggregate 12 reaches its elevated position shown in dotted lines in the figure. 3 and the instant at which the tamping aggregate, after having finished tamping a cross member 15, again reaches its upper position.
  • the detector 57 reacts each time the tamping aggregate 12 reaches its highest position.
  • the memory 53 on the basis of the measures described above, delivers on its output 58 an initialization signal, each time that the stuffing aggregate 12 has to start a new stuffing cycle, and that the detector 57 has announced the end of previous jam cycle. Simultaneously, the value stored in memory 53 is erased.
  • FIG. 3 Another sleeper detector 59 is shown very diagrammatically in FIG. 3, operating as a position detector and installed in such a way that it can check immediately, before the start of a tamping cycle, respectively the lowering of the tamping aggregate 12, if the crosspiece 15 to be tamped occupies the correct, expected position, relative to the tamping aggregate 12, so that during the lowering of the aggregate, the tamping tools penetrate with certainty into the ballast on each side of this crosspiece.
  • the sleeper detector 59 arranged in the anterior zone of the packing aggregate 12 or immediately before, on the machine, the triggering of a new tamping cycle is delayed or, if this cycle has already started, interrupted before the tamping aggregate is lowered.
  • the installation can, for example, be arranged so that the output signal from the sleeper detector 59 and the initialization signal on line 58 are applied to the inputs of a door and, so that a signal does not appears on line 61, for the triggering of the next stuffing cycle, only if the two signals are present simultaneously on the inputs of door 60.
  • a tamping cycle can naturally also start with the lowering of the tamping aggregate already tilted forward; in this case, the end of cycle signal is generated by a detector reacting when the tamping aggregate takes its tilted forward position, and the sleeper detector functioning as a position detector is located in the area where the lowering of the tamping aggregate, so that the presence of the crosspiece to be stuffed is announced, with a view to triggering the new tamping cycle, when this crosspiece is under the tamping tools.
  • the speed of advance of the machine is adapted at all times to the distance between two consecutive sleepers, this distance can vary without further. If it becomes smaller, respectively greater, the speed of advance v decreases, respectively increases.
  • a tamping cycle comprises the following phases, as indicated in FIG. 4: on the appearance of the trigger signal on the output line 61, the control cylinder 34 (FIG. 2) is actuated and the frame 20, with the tamping aggregate 12 is rapidly tilted during the interval b (FIG. 4) in its advanced position, in which it is at least approximately above the next cross member 15 to be stuffed.
  • the hydraulic cylinder 19 lowers the packing aggregate 12 during the time interval c, the picks 16 then entering the ballast on each side of the cross member concerned.
  • the picks 16 are again moved aside and the tamping aggregate 12 is again raised by means of the hydraulic cylinder 19 during the time interval e (FIG. 4), on whereby the new jam cycle is triggered.
  • the dead time is reduced to very little.
  • the tilting of the tamping aggregate 12 around a fixed cardanic suspension with a practically fixed transverse axis 13 is easier to control and with less important means than a displacement in translation of the tamping aggregate on rails guide. Since, due to the tilting, practically only the lower picks 16 of the tamping aggregate 12 have to make a complete displacement relative to the frame 2, displacement corresponding to the distance between two consecutive sleepers, the forces required res at the acceleration of the tamping aggregate are less than the forces necessary for the acceleration of the entire device in translation relative to the chassis 2, because the corresponding moment of inertia of the assembly is smaller, not to mention that the rolling friction forces on guide rails are eliminated.
  • the control of the machine during a tamping cycle can be carried out in another way than that described above.
  • the displacement phases of the tamping aggregate can be controlled as a function of a predetermined average working speed of the machine 1. It is naturally in principle possible to control all or part of the displacement phases described by hand , by an operator placed in a cabin located on the machine 1 and allowing observation of the packing aggregate.
  • the tamping aggregate 12 ′ comprises two pairs of tamping tools 14a and 14b mounted one behind the other on a common support 17 ′, these two tamping tools being produced identically, as described in relation to FIG. 2.
  • the two eccentric shafts 18a and 18b are driven by a common motor 44 by means of a belt 43.
  • the support 17 is again suspended pendulumally in a vertical longitudinal plane of the machine, as indicated by the arrows in a circular arc, by means of two hydraulic cylinders 19a and 19b whose lower ends are attached at two points of articulation 42a and 42b to the support 17 'and whose upper ends are articulated respectively to two transverse axes 13a and 13b on the chassis 2.
  • the parallelogram-shaped structure constituted by the support 17 ', the two hydraulic cylinders 19a and 19b and the part of the chassis 2 l they are attached ensures horizontal support, parallel to the track, of the support 17 ′, so that the two pairs of tamping tools 14a and 14b are always at the same height.
  • FIG. 6 A variant of this embodiment is shown diagrammatically in FIG. 6.
  • two pairs of tamping tools 14a and 14b are provided, each mounted on their own support 17a and 17b at the ends 47a and 47b of a rocker 45 of which the midpoint is attached to the end of the piston rod of a hydraulic cylinder 19 'provided for lifting the rocker 45 and the upper end of which is suspended pendulumly from the transverse axis 13 on the chassis.
  • a parallelogram articulation constituted on the one hand by the jack 19 and the rocker 45 and on the other hand by two arms 48 and 49 articulated together, shown in dotted lines.
  • the invention is not limited to the exemplary embodiments described, numerous variants being possible, both with regard to the execution of the tamping aggregate, its oscillating suspension and the control of the tamping cycles.
