Definitions

  • the invention relates to a continuously advancing railway work machine, comprising a main chassis provided with running members on the track and an auxiliary chassis supporting working members such as ballast tamping and lifting groups.
  • a main chassis provided with running members on the track and an auxiliary chassis supporting working members such as ballast tamping and lifting groups.
  • auxiliary chassis supporting working members such as ballast tamping and lifting groups.
  • the latter chassis being mobile and being able to move in translation along the main chassis under the action of drive means so as to advance, during the works, step by step relative to the track while the machine progresses continuously.
  • a machine of this kind is characterized, in operation, by a continuous advancement of the main chassis on which is superimposed a discontinuous advancement of the movable chassis supporting the working members.
  • the latter must in fact, in the case in particular of a track-stuffing machine, start, brake and stop at each work cycle, on a relatively short travel path determined for example by an interval of 50 to 60 cm. between, the sleepers of the track.
  • a tamping machine designed according to this principle makes it possible to obtain a significant increase in the working yield compared to tamping machines in which the working members are fixed relative to the main chassis and therefore require, for their movement from cross to cross, the acceleration and braking of the whole machine.
  • the accelerations and decelerations of the mobile chassis supporting the working members which appear at each work cycle are reflected, taking into account the significant weight of this mobile chassis, by longitudinal inertia reactions, which have repercussions on the main chassis of the tamping machine. and printing to the conductors located in the cabins significant tremors at the beginning and at the end of the displacement phase.
  • the resulting discomfort is all the more noticeable when one seeks to further increase the yield of the tamping machine by increasing the speed of movement of the mobile chassis.
  • Another effect of these inertia reactions is manifested in a loss of adhesion of the main chassis rolling on the rails at the moment when they appear. This in practice requires giving the main chassis the highest possible traction load and therefore leads to higher costs in terms of driving the machine.
  • the present invention proposes to provide a machine for continuous advancement, of the type described above, for which the inertia reactions generated by the discontinuous movements of the working members are eliminated, so that the increase in work efficiency is no longer limited by increasing discomfort of the personnel of conduct.
  • a machine of the type under consideration further comprises a mobile counterweight, which is coupled to the drive means of the mobile chassis so as to execute translational movements parallel to those of the mobile chassis but in the opposite direction. , the respective amounts of movement of the counterweight and of the mobile chassis including its working members being equal and opposite. In other words, the momentum vectors of these mobile elements are antiparallel.
  • the efficiency of the machine can therefore be increased by reducing the step-by-step advancement time of the mobile chassis and its working members.
  • the respective centers of gravity of the counterweight and of the mobile chassis, including the working members, should move on parallel lines as close together as possible, in order to minimize the torques on the main chassis.
  • the counterweight will be given a mass equal to the total mass of the mobile chassis and of the members that it supports, its translation speed being equal in module to that of the mobile chassis.
  • the counterweight In order to reduce the total mass of the machine, it is also possible to give the counterweight a mass less than the total mass of the mobile chassis and of the members that it supports; its translation speed must then be higher in module than that of the mobile chassis, the speed modules being in the inverse mass ratio.
  • Counterweight and movable frame can be operated in translation by a common motor means and be coupled together by a mechanical coupling means.
  • this coupling means can be constituted by a chain driven by a common motor and forming a closed loop with two strands parallel to the direction of movement of the movable frame and the counterweight, each of the latter being mechanically coupled to a respective one of said strands.
  • the counterweight and the movable chassis can also be actuated in translation by separate motor means and be coupled by synchronization means.
  • These motor means are advantageously hydraulic actuating members, coupled by electro-hydraulic synchronization means.
  • the machine represented in FIG. 1 comprises a main chassis 1 comprising a platform 51 and two strong longitudinal members 37, and resting on track 2, constituted by rails 3 and crosspieces 4 on a ballast bed 5, by l 'intermediate bogies 6, 7.
  • the wheels 8 of the bogie 7 are coupled to a drive motor 9 making it possible to advance the machine during the working periods in the direction indicated by the arrow 10.
  • the machine also comprises, at the front, a driving cabin 11 and an energy group 12 supplying in particular the motor 9 and working parts.
  • These include a pair of lifting-shifting groups 13 (one per row of rails 3) and a pair of tamping groups 14 (also one per row of rails; alternatively, as shown, only one group can be provided. tamping, able to move transversely from one file of rails to another).
  • Each lifting-shifting group 13 comprises a chassis 15 which can slide vertically along a column 16 under the action of a jack 17 to raise a file of rails gripped by two pairs of horizontal discs 18 carried by the chassis 15, and pivot horizontally around this column under the action of another jack to cause the line of rails to transversely slide through vertical discs 19 also carried by the chassis 15.
  • Each tamping group 14 comprises a frame 20 which can slide vertically along a column 21 under the action of a jack 22 and carrying a pair of vibrating tamping tools 23, actuated by jacks 24, which can penetrate into the ballast 5 on either side of a cross 4.
  • the working members 13, 14 are fixed below a mobile chassis 25, which can move by driving them along the main chassis 1, where it is supported by four vertical rollers 26 and guided by four horizontal rollers 27.
  • four other vertical rollers 28 take up the forces. directed upwards which the movable frame can undergo 25.
  • the rollers 26, 27, 28 cooperate with two lateral beams 29 belonging to the main chassis 1 and extending below the beams 37.
  • the movable frame 25 is coupled by a drive 30 to the lower strand 31a of an endless chain 31 which extends horizontally in the median plane of the main frame 1 between two idler gears 32, 33 with fixed horizontal axes 34, 35 compared to the main chassis.
  • One of these pinions is provided with a hydraulic gear motor group 36 for rotational drive.
  • the lift-shift operations of track 2 intended to eliminate the misalignments which it may have, are controlled by a leveling assembly with which the machine is equipped, which comprises a wire 43 stretched between the tops of two vertical rods 44, 45 widely spaced, resting on the track by wheels 46, 47. Between them is disposed a track feeler carriage 48 supporting a vertical rod 49 at the top of which is placed a displacement sensor 50 which, depending on the position it takes relative to the wire 43, controls the leveling-shifting groups 13 in leveling.
  • a leveling assembly with which the machine is equipped, which comprises a wire 43 stretched between the tops of two vertical rods 44, 45 widely spaced, resting on the track by wheels 46, 47. Between them is disposed a track feeler carriage 48 supporting a vertical rod 49 at the top of which is placed a displacement sensor 50 which, depending on the position it takes relative to the wire 43, controls the leveling-shifting groups 13 in leveling.
  • Another similar assembly provides lateral control relating to track alignment corrections.
  • a mass 38 forming a counterweight with respect to the movable frame 25 and its working members 13, 14.
  • This counterweight can be move in translation, supported by four vertical rollers 39, and guided by four horizontal rollers 40, following a rectilinear path parallel to the path of movement of the movable frame 25. It is for this purpose provided with a driver 42 engaged with the upper strand 31b of the chain 31.
  • the counterweight 38 including its annexes, has a mass equal to the working assembly 25, 13, 14 and its annexes. The distances traveled by these mobile elements are constantly equal, with equal speeds but in opposite directions thanks to the synchronization of their movements operated by the chain 31.
  • two independent translational drive systems can be provided, one for the movable frame 25 and the other for the counterweight 38, each of them comprising for example an endless chain actuated by a hydraulic motor as well as described above, or a horizontal hydraulic cylinder connected to the main chassis.
  • the synchronization of the opposite movements is then no longer carried out mechanically, but electro-hydraulically:
  • two potentiometric sensors can be provided for this purpose measuring the distance traveled respectively by the movable chassis and by the counterweight, which, according to a speed control law common, vary the flow of the two hydraulic translation motors or cylinders by means of an electro-hydraulic valve with proportional action.
  • the amount of compensating movement, equal to and opposite to that of the movable chassis is carried out using a counterweight of smaller mass than that of the movable chassis, but animated by 'a speed greater than that of the latter, the ratio between the masses being equal to the inverse ratio of the respective speeds.
  • This embodiment has the advantage of reducing the weights involved. However, it requires different strokes for the mobile chassis and for the counterweight.
  • the synchronization systems must ensure here a different speed ratio from the unit corresponding for example to a ratio of pinions, displacements of drive motors or different sections of hydraulic cylinders.
