Definitions

  • the present invention relates to a device for motorizing a switch.
  • the heelability consists of the possibility for a switch taken in the heel, that is to say in the direction where the two tracks meet in one, to allow the passage, without destruction, to a traffic coming from the corresponding track not to the orientation of the switch, the movement of the switch then being under the thrust due to the axle.
  • a switch is said to be peaked when the direction of traffic goes from the single lane to the differentiated lanes.
  • a switch includes two movable blades, called the right needle blade and the left needle blade. The terms right and left correspond to the location of the needle blades by looking at the switch on the side of the point. One of the blades is said to be open and the other pressed against their respective counter-rail.
  • French switches are not tailable, on the other hand the switches of the German railways are hookable.
  • French turnouts taken only in the heel as well as those that are taken in tip only at a speed equal to or less than 40 km / h have a motorization system comprising an internal timing of the motor in both positions, by a lyre system and drive roller.
  • the French system also uses a direct external locking system, for each blade, using "casing-pad" locks. These systems have only one operating bar actuating the two blades of right and left needles.
  • German switches are hookable.
  • a known device for an internally locked operating mechanism comprises an output shaft, provided with two special pinions each meshing with a rack of an operating bar.
  • One of the operating bars is linked to the right needle blade and the other to the left needle blade.
  • the plated blade is locked by means of a penetrating locking bar, at the end of rotation of the output and movement shaft of the operating bars, in a notch made in the operating bar of the plated blade.
  • the mechanism is reversible by tailgating, by action on the open blade, not locked but maintained by the force of a torque limiter.
  • this control is carried out by controllers attached to the blades themselves in the case of switches crossed only in the heel.
  • this lock includes the presence and locking controllers of the plated blade.
  • a known system consists in ensuring the operation and locking of the blades by two bars each fixed to a blade, the two blades being joined together by a spreader bar and the control of the position of the blades being ensured. by means of two other bars which bring the position information into a controller which may or may not be integrated into the motor.
  • the object of the present invention is to propose a motorization device making it possible to carry out all the intrinsically safe functions by a device comprising only two bars and ensuring greater security than the current French system by "casing-pad" locks with controllers.
  • the proposed system is also simpler and less expensive than this system or the foreign four-bar system.
  • the invention applies to the case of two locked blades and for a non-tailable switch.
  • the invention thus relates to a device for motorizing a switch consisting of two movable blades: a right needle blade and a left needle blade, the two said blades being connected, near their end, tip side , by a spreader bar, the right needle blade being linked in the vicinity of its point to a right operating rod, the left needle blade being linked in the vicinity of its point to a left operating rod, device comprising motor means for longitudinal drive of a right control bar and a left control bar linked respectively and in their extension to the right operating rod and to the left operating rod, said motor means and control rods being arranged in a casing subject to a fixed position , characterized in that it comprises, located in said casing, a movable assembly comprising a central body comprised between a right longitudinal slide and a left longitudinal slide, the two slides meshing on a common pinion mounted in free rotation in said central body, the travel of the two slides, relative to said central body, being limited by stops, said drive motor means acting on said body this ntral of said movable
  • each floating pin has at each of its ends a rolling roller cooperating, outside said grooves, by rolling, with its adjacent locking plate.
  • each locking plate comprises, in the immediate downstream vicinity of a said groove, considered with respect to the direction of movement of the movable assembly towards said groove, an anti-overtravel stop of said floating pin.
  • the drive means comprise a ball screw cooperating with a nut secured to said central body of said movable assembly, the ball screw being driven in rotation by a gear motor by means of a torque limiter.
  • the means for detecting the rotation of said common pinion comprise a ring integral in rotation with said common pinion, said ring being traversed by said ball screw and its opening being sufficiently large relative to the diameter of the screw to allow it a certain degree. of rotation with the pinion.
  • said ring comprises a lateral lever cooperating, via a slide, with a rod parallel to said screw and to the control bars, said rod being fixed at each of its ends to the end of a rocker which is articulated in rotation at its other end to said casing, one of the two rockers comprising a cam cooperating with at least one switch located in a fixed position, said slide sliding freely on said rod and being forked by the end said lateral lever.
  • the upper part of the ring comprises a cam which cooperates with at least one contact fixed on a nut cage of the nut of the ball screw, said cage being integral with said body central, the information of said contact being transferred to a fixed terminal block secured to said casing by means of a sheet of conductors protected by a fixed lower gutter, linked to the casing and an upper gutter sliding with the concavity turned downwards, secured of said central body.
  • a switch is partially shown which comprises a right needle blade 1 and a left needle blade 2.
  • the switch shown corresponds to a path deviated to the right and it is in position corresponding to the passage of the single lane towards the deviated lane on the right taken in this direction, that is to say in point or in the opposite direction, that is to say in heel.
  • the left needle blade 2 is therefore pressed against the straight counter-rail 3 and the right needle blade 1 is therefore open, that is to say spaced from the counter-rail 4 initiating the deflected path to the right.
  • the needle blades 1 and 2 are connected by a spacer bar 5 provided with a device 6 for adjusting the spacing.
  • a right operating rod 7 is linked perpendicular to the right needle blade 1 in the vicinity of its tip and similarly, a left operating rod 8 is linked perpendicular to the left needle blade 2 in the vicinity of its tip.

  • the control rods 9 and 10 are fixed to the operating rods 7 and 8 in their extension by means of yokes 11 and 12 allowing adjustment the length of the transmission.
  • the operating bars are part of the motorization device 100 specific to the invention.
  • the entire motorization device 100 is located in a casing 13 fixed securely on two crosspieces 14 and 15 extending beyond the track.
  • the operating device firstly comprises motor means allowing the longitudinal, that is to say axial, drive, of the right and left control rods 9 and 10 by means of a mobile assembly 16.
  • These motor means comprise a geared motor 17 which rotates, by means of a belt 18 and a torque limiter 19, a ball screw 20 fixed axially and which cooperates with a nut 21 secured to a central body 22 of the moving crew 16.
  • the nut 21 of the ball screw 20 is housed in a nut cage 23 secured to the central body 22.
  • the mobile assembly 16 therefore comprises a central body 22, driven longitudinally as has just been said, between a right longitudinal slide 24 and a left longitudinal slide 25. These two slides mesh on a common pinion 26 which is mounted in free rotation in the central body 22.
  • the pinion 26 is integral with a member, shown in these simplified figures 1, 3, 4, 5 and 6, in the form of a sector 27 provided with '' a notch 28 which cooperates with an electrical contact 29 for controlling anomaly, thus making it possible to detect a possible rotation of the pinion 26 indicative of a defect: part rupture, twisted part, fastening having play, in any one parts ensuring the chain of operation of the needle blades 1 and 2.
  • This fault detection system, linked to the rotation of the common pinion 26 is described in more detail in relation to FIGS. 7 to 12 illustrating two concrete examples of embodiment .
  • This moving element 16 as seen in FIGS. 1, 3, 4 and 6, is arranged in the fixed casing 13, between a right locking plate 30 and a left locking plate 31 fixed in the casing 13. These plates locking are parallel to each other and to the control bars 9 and 10. Furthermore, the right control bar 9 is located between the right locking plate 30 and said equipment mobile 16 while being housed in the right longitudinal slide 24. In the same way, the left control bar 10 is located between the left locking plate 31 and the mobile assembly 16 while being housed in the left longitudinal slide 25.
  • the bar right control 9 has two notches 32 and 33 in which are housed respectively drive and locking pins 34 and 35. These pins are cylindrical and mounted "floating" and with a vertical axis between the right locking plate 30 and the slide longitudinal right 24.
  • the left control bar 10 also has two notches 36 and 37 in which are housed respectively drive and locking pins 38 and 39 mounted in the same way between the left locking plate 31 and the left longitudinal slide 25.
  • each pin 34, 35, 38 and 39 is immobilized in the direction of the axis of its control bar and therefore necessarily moves with it.
  • the right locking plate 30 has two vertical locking grooves 40 and 41 with oblique side walls moving away from the bottom of the groove towards its opening facing the right control bar 9.
  • the left locking plate 31 includes two locking grooves 42 and 43 vertical and with oblique lateral walls deviating towards its opening facing the left control bar 10.
  • the depth of the grooves 40 to 43 is at most equal to D 2 , D being the diameter of a floating pawn.
  • the width of the mobile assembly 16 constituted in fact by the distance separating the external sides of the two slides 24 and 25 between the locking plates 30 and 31 is stepped over three distinct widths comprising, at each end of the moving element, a first stage 44, 44A whose width is equal to the distance L separating the two locking plates 30, 31 minus twice the diameter D of a floating pin.
  • This first stage is followed on each side, approaching the middle of the moving assembly, a second stage 45, 45A of width between L-2D and LD, and finally a central stage 46 of width greater than that of the second stage and at most equal to L.
  • the passage from the first stage to the second stage takes place by an oblique wall.
  • the distance between two notches of a control bar, for example the notches 32 and 35 is at least equal to the length of the central stage 46 plus the length of the two second stages 45 and 45A, but at most equal to the length of central stage 46 plus the length of a second stage 45 or 45A plus the length of a first stage 44 or 44A, so that, as can be seen in the figures, the floating pieces always remain located between the moving element 16 and the locking plates 30 and 31.
  • Limit switches 47 and 48 are actuated respectively at the end of the travel to the right and at the end of the travel to the left by the central body 22 of the moving element 16. The actuation of these contacts stops the drive means d training of this central body.
  • contacts 49, 50, 51 and 52 actuated by the slides 24 and 25 carry out position and locking control, in both directions, of the needle blades 1 and 2.
  • the left needle 2 is pressed and the right needle 1 is open, they are perfectly locked.
  • the floating pin 35 is housed both in its notch 33 of the bar 9 and in the groove 41 of the right locking plate 30 and cannot come out of it, because the second stage 45A of the mobile assembly 16 blocks it. It is the same for the floating pin 39.
  • the two control bars 9 and 10 are therefore locked in both directions by the pins 35 and 39, partially introduced into the grooves 41 and 43 of the locking plates.
  • the geared motor 17 is started, which causes the ball screw 20 to rotate and therefore drive the central body 22 of the moving assembly to the right. 16.
  • the displacement of the central body 22 also causes, via the pinion 26, the simultaneous displacement of the slides 24 and 25 until the inclined flanks 53 and 54 (FIG. 5) of the slides 24 and 25 come to bear against the drive and locking pins 34 and 38. From that moment, as no link is defective, the mechanical link chain has no break and the two needle blades 1 and 2 are rigidly connected by a spreader bar 5, the continuation of the movement leads, via of these pins 34 and 38, the movement to the right of the right and left control bars 9 and 10, and therefore of the blades 1 and 2, without any possible rotation of the pinion 26.
  • the contacts 49 and 50 are actuated indicating the correct positioning and locking of the control bars 9 and 10 by the pins 34 and 38 blocked in the grooves 40 and 42 of the locking plates 30 and 31.
  • the right needle blade 1 is then pressed against the counter-rail 4 and the left needle blade 2 is then open, that is to say in the opposite position to that shown in FIG. 1.
  • the anomaly control contact 29 has not not moved.
  • the switch however, has worked, and is locked by means of the left control bar 10 and the spreader bar 5.
  • the fault is in any case signaled by the contact 29 and whatever the fault is on any part of the chain, including the fixing of the casing 13 on the cross members 14 and 15.
  • the sector 27 is oriented towards the side of the part of the frame, or of the faulty operating chain, which can facilitate its search, in the case in particular where this defect is hardly visible: loosening of a part. for example.
  • Figures 7, 8 and 9 give a practical embodiment of the main parts of the device in the case of a first example of realization of the fault detection device cooperating with the anomaly control contact 29. In reality first, these are two contacts 29 because, for safety reasons, a contact is placed on each positive and negative wire of the electrical circuit.
  • central body 22 which has an I-shaped section.
  • the right and left longitudinal slides 24 and 25 are in fact, for reasons of practical realization, each made in two half-slides: 24A, 24B for the right slide 24, and 25A, 25B for the left slide 25.
  • Each half-slide therefore includes a rack portion meshing with the common pinion 26 integrated in the central body 22.
  • the ball screw 20 axially drives the central body 22 by means of a nut 21 mounted in a nut cage 23 secured to the central body 22.
  • the nut 21 is mounted in the cage 23 by means of an elastic ring 57.
  • an anti-overtravel stop 58 which has the purpose of forcing the floating pin 35 to penetrate into its locking groove 41.
  • Such a stop 58 is also arranged downstream of each locking groove.
  • each half-slide 24A, 24B, 25A and 25B has a recess 66 in which penetrates a lug 67 carried by the central body 22.
  • the central body 22 therefore carries four pins 67.
  • the fault detection means firstly comprise a ring 68 secured to the common pinion 26.
  • This ring has an opening large enough to allow it a certain degree of rotation, integrally with the pinion, despite the passage of the ball screw 20 in the ring.
  • a lateral lever 69 On the upper part of the ring is fixed a lateral lever 69, the end of which ends in a portion folded vertically and comprising a notch 70 into which a slide 71 enters.
  • the slide 71 is mounted in free, axial and rotational sliding , on a rod 72 arranged parallel to the axis of the screw 20.
  • this rod 72 At each of its ends, this rod 72 is fixed to the end of a rocker, respectively 73 and 74, of which another end is articulated in rotation at casing 13.
  • the rocker 73 forms a cam which cooperates with the abnormality control contacts 29.
  • the cam rocker 73 cooperates with the contacts 29 in the two directions of rocking of the rod 72, that is to say in the two directions of rotation of the ring 68.
  • the rockers 73 and 74 are provided with springs 75 and 76 exerting a slight force so as to swing the rod 72, and to actuate the contacts 29 by the rocker-cam 73 in the event of failure to fix the lever 69 on the ring 68. This provides security ensuring signaling a fault on the fault detection device.
  • Two springs 75 and 76 are placed and not just one, always for safety and redundancy.
  • FIGS 10, 11 and 12 show a preferred embodiment of the invention with regard to the fault detection device, the other parts being identical.
  • the left locking plate 31 has been omitted for reasons of space in the drawing.
  • the common pinion 26 is always integral with the ring 68, but on this is directly fixed a cam 81 which cooperates directly with the contacts 29 fixed this time no longer at a fixed station on the casing 13, but on the cage 23 of the ball screw nut, by means of a fixing bracket 82.
  • a fixing bracket 82 As the contacts 29 are fixed on the nut cage 23 secured to the central body 22, therefore on a moving part, the information of these contacts is attached to a fixed terminal 83 secured to the casing 13 by a fixing plate 84.
  • the electrical connection between the contacts 29 and the fixed terminal 83 is produced by a sheet of conductors 85 protected by a fixed lower gutter 86 fixed to the plate 84 and a sliding upper gutter 87 linked to the central body 22 by the bracket 82.
  • the upper gutter 87 has of course its concavity turned downwards.
  • the ring 68 carries an arrow 88 and the nut cage 23 a control zone 89 (see FIGS. 7 and 8) which allow these adjustments to be made.
  • the zone 89 has a certain width range corresponding to a correct adjustment without stressing the fault contacts 29.
  • the assembly constitutes an intrinsically safe motor-controller device ensuring all the operating and locking functions of the needle blades as well as the control of the effective position of the blades and the indication of a fault.
  • the system also makes it possible to ensure two functions by the same member: the operating movement and the locking by the same part: the floating pins. There is thus necessarily locking if the movement has been carried out until the correct positioning. This is not the case in current systems where it is possible to properly actuate the needle blades without locking them, in the case where a part is broken for example.
  • control bars 9 and 10 are blocked in both directions, and an axial force possibly exerted on them is transformed, via the floating pins into transverse and longitudinal forces on the locking plates 30 and 31 easily held firmly in the housing 13, but in no axial force on the moving element 16.
  • the system is therefore extremely robust.
  • the locking plate 30 is supported for example on a spacer 90 which is dimensioned according to the maximum forces expected, just as the locking plate 31 is supported on the edge 91 of the casing.
  • the plates 30 and 31 are fixed against these supports 90 and 91.
  • the anomaly control contacts 29 consist either of contacts which, once actuated, do not return by themselves, but which must be returned to the rest position manually, or contacts which return from them - even when they are no longer pressed, but which actuate a relay which must be reset manually. In all cases, the fault indication persists until manual intervention has been carried out.
  • the invention makes it possible to carry out all the intrinsically safe functions by a motor controller with only two control bars.
  • the principle consists in introducing between two different and sufficient operating and locking chains, each to ensure safety, an element (mobile equipment 16 with "differential" and pinion rotation detection device 26) which checks at each operation the good condition of all the elements and assemblies constituting the two chains formed by: - the floating pins which ensure the operation and the locking, - the control bars 9 and 10, - the operating rods 7 and 8, - the spreader bar 5, - length settings 6, 11 and 12, the axes 92 and fixings 93 of the rods 7 and 8 and of the spreader bar 5 to the blades 1 and 2, as well as the fixing axes 94 of the rods 7 and 8 to bars 9 and 10.
  • the device is also capable of verifying the fixing itself of the casing 13 and of the crosspieces 14 and 15.
