Definitions

  • the present invention relates to a device for operating 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 switch 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 shaft and movement 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.
  • Document FR-A-2 338 832 discloses a steerable switch operating device comprising two operating rods each extended by a cam facing each other between which is an anchor with two rollers pivoting about a fixed axis.
  • the cams are extended by a rod and a piston, which is housed in a cylinder, the bottom of which is linked to a common operating fork set in motion by motor means.
  • a spring is located in each cylinder, between the bottom of the cylinder and the piston.
  • the object of the present invention is to propose a switching switching device, modular, capable of adapting to all the functions: heelable or not, and whatever the operating stroke of the blades; much simpler than the internal wedging system by lyre and drive roller, or external by casing-bearing locks, or than the German hookable systems with special pinions and racks with locking bar and notch; finally more robust and safer than all existing systems.
  • the subject of the present invention is therefore a device for operating a switch consisting of two movable blades: a right needle blade and a left needle blade, one of the blades being open and the other pressed against their respective counter-rail, at least the plated blade being locked, device comprising a straight operating bar, linked perpendicularly to the right needle blade in the vicinity of its tip, a left operating bar, linked perpendicular to the blade left needle near its tip, motor means for axially driving said operating bars, characterized in that it comprises a carriage driven in axial translation by said motor means, said carriage being axially movable between a right locking plate and a left locking plate, parallel to each other and to the axes of said operating bars, said plates being held by a frame, the right operating bar being located between the right locking plate and said carriage being housed, at least in part, in a right longitudinal groove of said carriage, the left operating bar being located between the left locking plate and said carriage being housed, at least in part, in a left longitudinal groove of said carriage
  • one of the two locking plates comprises two said vertical locking grooves.
  • the two right and left locking plates each have two said locking grooves.
  • said motor means are reversible.
  • the term “reversible” means that the motor, whatever it is, not being powered, can be driven as a receiver, for example by force on an operating bar. not locked and linked to a needle blade undergoing a hooking effort.
  • the device is characterized in that it comprises a carriage axially movable between a locking plate and a fixed guide wall, integral with a frame, said operating bar being located between the locking plate and the carriage being housed, at least in part, in a longitudinal groove of the carriage, said operating bar being provided with two floating pins, cylindrical, vertical, perpendicular to said longitudinal groove and housed, each, in a notch made in the bar, the locking plate comprising two vertical grooves with oblique lateral walls moving away from the bottom of the groove towards its opening and whose depth is, at most, equal to the half-diameter of a floating pin , and in that the distance of the separation separating said locking plate from said carriage extends over three distinct dimensions comprising, at each end of the carriage t, a first spacing of dimension X
  • each floating pin advantageously comprises, at each of its ends, a rolling roller cooperating, outside said grooves, by rolling, with said locking plate.
  • the plate or plates of locking comprises, in the immediate downstream vicinity of a said groove, considered with respect to the direction of movement of the carriage towards said groove, an anti-overtravel stop of the floating pin.
  • each floating pin is held axially by a collar integral with the pin, of a diameter greater than that of the pin, penetrating, on the one hand, into a longitudinal groove of the locking plate associated with the pin considered and d on the other hand, in an enlarged portion of said slot for housing the pin in a maneuvering bar.
  • the drive means comprise a ball screw with nut connected to the carriage, the ball screw being rotated by a gear motor by means of a torque limiter.
  • FIG. 1A there is shown schematically, to the left of the operating device, a switch.
  • This switch comprises a right needle blade 1, a left needle blade 2, a direct track cross-rail 3 and a deflected track cross-rail 4.
  • the switch is in position corresponding to traffic from, or going to, the deviated lane.
  • FIG. 1E the switch is in position corresponding to traffic on the direct lane.
  • the transition from one to the other position is made by the displacement of the two blades of right and left needles, the right blade 1, open, becoming plated and the left blade 2, plated, becoming open.
  • a traffic in the direction of the arrow F1 is said to take the point switch
  • a traffic in the direction of the arrow F2 is said to take the heel switch
  • a traffic in the direction of the arrow F3 is said to take the switch in tailgating.
  • the switch is said to be hookable if the passage of the switch in the direction of the arrow F3 does not destroy anything, the latter passing from the deviated track position to the direct track position under the axle pressure on the right blade 1 open.
  • This kind of operation is possible with the operating device shown in Figures 1A to 1E and its operation is shown in Figures 2A to 2C.
  • FIG. 1E it is the direction represented by the arrow F2 which is said to take the switch in tailgating and the direction F3 which is said to take the switch in heel.
  • the switch operating device comprises a straight operating bar 5 linked to the right needle blade 1 perpendicular to it and in the vicinity of its end and a left operating bar 6 linked to the left needle blade 2 perpendicular to it and in the vicinity of its end.
  • These two operating bars can be moved axially by motor means, not shown in these figures, by means of a carriage 7, driven in axial translation by these motor means, and floating pins 8, 9, 10 and 11 .
  • each operating bar is provided with two of these pins.
  • the carriage 7 is moved in axial translation between a right locking plate 12 and a left locking plate 13 rigidly fixed in a frame not shown.
  • the right operating bar 5 is located between the right locking plate 12 and the carriage 7 and at least partially housed in a right longitudinal groove 14 (see Figures 6 and 8) in which it can slide.
  • the left operating bar 6 is located between the left locking plate 13 and the carriage 7 and at least partially housed in a left longitudinal groove 15 ( Figures 5 and 8) in which it can slide.
  • Each floating pin 8 to 11, cylindrical, is arranged vertically, that is to say perpendicular to the longitudinal grooves 14 and 15 of the carriage 7, in a notch, respectively 16 to 19, of the operating bar.
  • each pin is immobilized in the direction of the axis of its operating bar and therefore moves with it, by its notch, and laterally held between the carriage and its locking plate.
  • the right locking plate 12 has a vertical locking groove 20 with oblique side walls which move away from the bottom of the groove until it opens.
  • the left locking plate 13 has a vertical locking groove 21 with oblique walls.
  • the width of the carriage 7 is stepped over three distinct widths comprising at each end a first stage 22, 22A whose width is equal to the distance L separating the two locking plates 12 and 13 minus twice the diameter D of a pawn floating 8 to 11.
  • This first stage is followed on each side, approaching towards the middle of the carriage of a second stage 23, 23A of width between L-2D and LD and finally of a central stage 24 whose width is greater than that of second stage and at most equal to L.
  • the depth of gorges 20 and 21 is at most equal to D 2 .
  • the distance separating two notches such as 16 and 17 from the same operating bar is at least equal to the length of the central stage 24 plus the length of the two second stages 23 and 23A but at most equal to the length of the central stage 24 plus the length of a second stage 23 or 23A plus the length of a first stage 22 or 22A, so that, as can be seen in FIG. 1A, the two floating pins 10 and 11 always remain between the carriage and the corresponding locking plate.
  • the floating pin 10 is housed both in its notch 18 of the left operating bar 6 and in the locking groove 21 of the left locking plate 13 and cannot come out of it because the second stage 23A carriage prevents it.
  • the left operating bar 6 is therefore blocked in both directions, the axial force, possibly, exerted on it transforming, via the floating pin 10, into transverse and longitudinal forces on the locking plate 13 held by the frame, but in no longitudinal effort on the carriage 7.
  • the first stage 22A When the first stage 22A is located in front of the pin 10, it can come out of the groove 21; at this moment, the inclined flank 25 for passage from the first stage 22 to the second stage 23 comes to bear on the floating pin 11 and therefore also on the left operating bar 6 by means of the notch 19, thus driving the bar 6; the pin 10 is then forced to leave the groove 21 thanks to the inclined wall of the groove 21.
  • the straight operating bar 5 is also driven by the pin 9 and the inclined flank 26 (FIG. 1B).
  • Figure 1C Axial displacement of the carriage 7, bars 5 and 6 assembly.
  • FIG. 1D The pin 9 arrives opposite the groove 20, a stop 45, not shown in these figures but which we see in Figure 6, prevents the pin 9 to go further and it is housed in the groove 20, which allows the carriage 7 to continue its race, the stage 23 having just covered the floating pin 9.
  • FIG. 1E the right operating bar is blocked and the switch has changed position giving access to the direct route.
  • FIGS. 1A to 1E only one bar is blocked: the left operating bar 6 in FIG. 1A and the right operating bar 5 in FIG. 1E.
  • FIGS. 3A to 3E are identical to FIGS. 1A to 1E but relate to a non-hookable switch for which the two needle blades, both the open blade and the plated blade are blocked and in the two positions of the switch.
  • the right locking plate 12 carries two locking grooves: 20 and 28.
  • the left locking plate 13 carries two locking grooves: 21 and 29.
  • the two needle blades are interconnected by a spacer bar 70A.
  • FIGS. 4A to 4E show a variant representing a switching operation device in which the two right and left needle blades 1 and 2 are linked and moved by a single operating bar 30.
  • the switching then only comprises only one locking plate 31 and is not heeling, the locking plate 31 comprising two locking grooves 32 and 33.
  • the carriage 7 is only provided with rollers 34 and 35 for rolling and guiding the carriage which bear against the frame 36.
  • the depth of the grooves 32 and 33 is also at most equal to half the diameter D of the floating pins 10 and 11.
  • the spacing between the locking plate 31 and the carriage 7 is three-stage: at each end a first spacing X1 equal at least to diameter D of the pins; then a second spacing D 2 ⁇ X2 ⁇ D; finally, in the center of the carriage, this spacing less than X2.
  • the passage from the spacing from X1 to X2se is made by inclined walls 70 and 80.
  • Such a case can apply, for example, to the sidings of sidings for crossings on single lanes with two-way traffic.
  • FIGS. 5 to 8 give a practical embodiment of the device according to the invention in the case of a device with two operating bars 5 and 6.
  • Figure 5 is a simplified general view from above. We recognize the right operating bar 5, the left operating bar 6, the right and left locking plates 12 and 13 held by a frame 36 between sleepers 37 and 38. In the example shown, Figure 5, the plates each have two locking grooves 20, 28 and 21, 29 respectively.
  • the operating bars 5 and 6 come out on both sides of the frame 36 so that the device can be placed either on one side or the other of the track or even between the two rails .
  • the carriage 7 is driven axially by a ball screw 39 driven in rotation by means of a toothed belt 40, a torque limiter 41 and a geared motor 42.
  • the ball screw 39 actuates the carriage 7 by means of its nut in two parts 43 and 44 (FIG. 8) secured to the carriage 7.
  • Figure 6 shows an exploded perspective view of carriage 7 or more exactly one part of the carriage 7, the upper part carrying the two-part nut 43, 44 having been cut, the right operating bar 5, the left operating bar 6 as well as the two locking plates 12 and 13 and the four floating pawns 8, 9, 10 and 11.
  • the locking groove 21 carries, downstream relative to the direction of advance of the carriage towards this groove, an anti-overtravel stop 45 of the pin 10 forcing it to enter the groove 21.
  • the other grooves, not shown in this figure, also each carry such an anit-overtravel stop.
  • each floating pin is held axially, that is to say vertically, by a flange 46, 46A which penetrates, on the one hand, into a longitudinal groove 47, 47A of its associated locking plate and on the other hand, in an enlarged portion 48, 48A of the notches 16 to 19 for housing the pins in the operating bars 5 and 6.
