Definitions

  • the invention relates to an electrically actuated mechanism for rail switchpoints.
  • An electrically actuated mechanism for rail switchpoints in which two internal operating rods, a coupling member and a slide form actuating, checking, and locking devices, is described already in DE-A-3 020 788.
  • the two internal operating rods of this mechanism are arranged side-by-side and parallel to each other.
  • the slide overlies the internal operating rods and is slidable in the same longitudinal direction as the said rods.
  • the coupling member is interposed between the two internal operating rods and the slide.
  • the coupling member is coupled to the slide by driving members which are resiliently collapsible within certain limits and automatically disconnectable when said limits are exceeded.
  • a locking clamp (Verschlul3klammer) is hinged to each operating rod.
  • These locking clamps have dove-tail-like heads with projections which cooperate with driving abutments of the coupling member).
  • the coupling member is disengageable, on completion of the switchpoint movements in one direction, from the one of said locking clamps and in the opposite direction from the other locking clamp.
  • IT-A-12485/83 describes an electrically actuated mechanism for rail switchpoints, of the type wherein the actuating, checking, and locking devices are arranged within the container enclosing the swtichpoint mechanism, and the two internal operating rods cf this mechanism are arranged side-by-side and parallel to each other, whilst an elastic coupling device which acts as a force limiter performing the function of friction, trailing, approach, and stabilizing the points, is integrated in the internal operating rods, and the said mechanism comprises a slide which overlies the internal operating rods and is slidable in the same longitudinal direction as the said rods by the action of an electrical motor which is alternately rotable in either direction, the elastic coupling device being connected to the overlying slide through driving members which. are resiliently collapsible within certain limits and automatically disconnectable when said limits are exceeded.
  • This invention aims to further improve the electrically actuated swtichpoint mechanisms while maintaining all the advantages thereof in respect oft he prior points mechanisms, particularly by providing an approach action, i.e., an action to force the closing blade with a predetermined presssure against the rail-stock, thus overcoming small obstacles that may be interposed between the blade and the rail stock, and permitting to ascertain the presence and the exact positioning of the rail-stock.
  • an approach action i.e., an action to force the closing blade with a predetermined presssure against the rail-stock
  • the switch-points mechanism according to the invention may be applied, similarly to the known Italian Railways switch-mechanisms, either to simple switch-points and to double-slip switch-points.
  • the assembling of said mechanism and its connection to the switch-points are not shown in the drawing since they are known and obvious to those skilled in the art.
  • the switch- points mechanism moves the switch-blades through external operating rods (not shown) which are connected by means of pivot pins to the corresponding internal operating rods T1 and T2 of the mechanism.
  • the position of each blade-tip is re-transmitted to the switch-mechanism through similar external checking rods (not shown) connected by means of pivot pins to the corresponding internal checking rods C1 and C2 of the mechanism.
  • the external operating rods and checking rods are connected to the switch-blades, preferably, by means of ball joints so as to permit a considerable ease of movement and eliminate stresses and friction losses which enhance wear and are detrimental to regularity.
  • the switch-points mechanism comprises a D.C. electrical motor (not shown) capable of rotating, alternately, in either direction. Two separate feeding conductors and one common return conductor are connected to said motor.
  • a pinion (not shown) that through a train of gears (not shown) moves a gearwheel 1 keyed on the shaft of a worm-screw 2 which meshes with a corresponding nut-screw of a slide 3 which is slidably mounted in suitable guides (not shown) to move in the same longitudinal direction as said worm-screw 2.
  • the slide 3 can effect longitudinal reciprocatory movements depending upon the direction of rotation of the worm-screw 2.
  • the system comprising the worm-screw 2 and respective nut-screw is of the balls or rollers type, or the like, whereby it has a high efficiency and enables the use of a motor of much smaller power and size as well as a reduced wear of the moving members due to the absence of sliding friction.
  • the slide 3 is arranged above the two internal operating rods T1 and T2 and is connected to these rods by means of an elastic coupling device comprising a coupling member 4 having, preferably, a square- section parallelepipedal outer contour and is accommodated in a suitable seat between the two rods T1 and T2.
  • Said coupling member 4, on the top side of which the slide 3 reciprocates slidingly, is formed with a cylindrical axial recess.
  • Two cylindrical sliders 5 (only one of which is exposed) are slidingly accommodated within said cylindrical recess and are positioned in the opposite end portions of said recess, a compression spring 6 being interposed therebetween.
  • a suitable shaped plate 7, 7' Accommodated in a longitudinal slot of each slider 5 is a suitable shaped plate 7, 7', which is thus pivotably mounted in the respective slider about the axis of a transverse pivot 8.
  • Each plate 7, 7' has formed therein a suitably shaped slot slidably receiving a guide roller 9 which is solidary with the body of the coupling member 4.
  • the rollers 9 are intended to prevent the pivotable plates 7, 7' from rotating abouttheiraxes 8 during the normal operation.
  • each pivotable plate 7, 7' is provided with a recess 10, 10' and protrudes from the top side of said coupling member whereon said slide 3 reciprocates slidingly.
  • Thrust rollers 11, 11' mounted at the ends of the slide 3 and disposed transversely to the path of movement thereof will abut against said recesses 10, 10'.
  • the operating rods T1, T2 are displaced in either direction by the slide 3 by means of the coupling member4 which, for this purpose, comprises end portions 12,12' co-operating with driving abutments 13, 13' integral with the operating rods T1, T2, and with abutment projections 14, 14' of drive members 15, 15' for the operation of approach (facing the points), which are pivotably mounted on the operating rods T1, T2.
  • the coupling member4 which, for this purpose, comprises end portions 12,12' co-operating with driving abutments 13, 13' integral with the operating rods T1, T2, and with abutment projections 14, 14' of drive members 15, 15' for the operation of approach (facing the points), which are pivotably mounted on the operating rods T1, T2.
  • the front end portion 12 of the coupling member 4 co-operates with a stationary driving abutment 13 of the operating rod T2 and with a pivotable approach drive member 15 of the other operating rod T1.
  • To rear end portion 12'of the coupling member4 co-operates with a stationary driving abutment 13' of the operating rod T1 and with a pivotable drive member 15' of the other operating rod T2.
  • the two operating rods T1, T2 will present, alternately, one a pivotable approach drive member 15, 15' and the other a stationary driving abutment 13, 13'.
  • the approach drive members 15, 15' are pivotable about pins 16, 16' secured to the respective operating rods T1, T2 and are formed with two opposite abutment projections 14,14' receiving the thrusts of the end portions 12,12'of the coupling member4.
  • the pivotable approach drive members 15,15' are formed with guide projections 17,17' slidable on the side walls 19, 19' of the guide and support baseplate of the operating rods T1, T2 and which, on completion of the switch-points movement in either direction, are received alternately into recesses 18, 18' formed in the side walls 19, 19'.
  • 15' is a cylindrical recess containing a push-rod 20, 20' having a chisel-shaped tip protruding out of the head portion of the respective approach drive member and is pushed by a cup-shaped spring 21 against a respective roller22, 22' which is fixed to the respective operating rod T1, T2.
  • the switch-points mechanism according to the invention is provided with a points lock of the transverse lock type operatively similar to that of the Italian Railways switch-points mechanism used heretofore and, therefore, it has all the advantages thereof as to strength, reliability and safety.
  • the locking action is obtained by means of a transverse locking member 23 provided with teeth 25, 26 which engage suitable notches 27, 28 of either one or the other of the internal operating rods T1, T2 and checking rods C1, C2 connected to the points in the closed position thereof, thus locking them in said position.
  • the inclined flat of the rod T2 abuts against a similar inclined flat of the tooth 25 of the locking member 23 and pushes the latter laterally so that the tooth 26 will engage the notch 27 in the rod T1 in the closure position thereof, so as to lock it.
  • the switch-points mechanism is also provided with a check device which is similar to that of the heretofore known Italian Railways switch-point mechanisms, and the description thereof may, therefore, be omitted.
  • This check device supplies, via suitable relays, the signals of positioning and locking of the points in the two positions thereof to a central control station.
  • Said check device comprises a system of electrical knife contacts mounted on two shafts which are driven to the two end positions by said operating rods. The exact closed position of said contacts in either end position, is the confirmation of the exact positioning of the operating rods and transverse lock 23 and, therefore, of the exact positioning of the switch blades in either position, and of their firm locking.
  • the check circuit only closes if the contacts of both shafts are in their proper positions.
  • the switch-point mechanism moreover, comprises a limit-switch device the construction of which is apparent to those skilled in the art. Such a device is intended to open, upon completion of a switchpoint operation, the feed circuit to the motor and to pre-set the same for the successive reverse operation.
  • Said limit switch device comprises two sets of knife- contacts (not shown) controlled by the slide 3 which, at the end of its movement, establishes the required electrical contacts for the function mentioned above, on either one or the other set of contacts.
  • the dimensions, construction and method of mounting of the switch-points mechanism according to the invention are, preferably, such as to permit its perfect interchange abilitywith the knonn Italian Railways P.64 switch-points mechanism without modifying the existing external members (foundation slabs, tierods, etc.).
  • the stroke of the switch-blades may be maintained at 150 mm.
  • the sequence of operations for throwing over the points are as follows: movement of the spaced apart blade towards the stock-rail, removal of the point lock, throwing over of both blades, stopping of a blade in the close-by-position, pursuance of the movement of the spaced apart blade and new application of the point lock.
  • the operating rod T1 is related to the spaced part blade and the operating rod T2 is related to the close-by blade that is rigidly locked by the transverse locking member 23 by means of the respective tooth 25 engaged in the notch 28 of said rod T2.
  • the operatin occurs in the direction of the arrow F.
  • the end portion 12 of the coupling member 4 engages the abutment projection 14 of the approach drive member 15 which is pivoted on the rod T1 of the spaced apart blade and is spaced from the stationary drive member 13 of the rod T2 of the close-by blade.
  • the overlap permits the opened blade to effect limited displacements without affecting the locking of the closed blade.
  • the switch-points mechanism according to the invention has the advantage to take up, due to the elastic coupling device between the slide 3 and operating rods T1, T2, any displacement of the rod for the opened blade due to shocks or vibrations by moving its back to its original point-locking position.
  • the slide 3 Upon the opposite operating manoeuvre, the slide 3 is moved in the direction opposite to that of the arrow F and causes movements which are similar but contrary to those described above.
  • the switch-points mechanism according to the invention may be operated also manually by means of a handle to be coupled with a suitable clutch (not shown), which also opens an electrical contact in the operating circuit, thus preventing any simultaneous electrical operation.
  • the thrust of the slide 3 is taken up by the cup-shaped spring 21 which, thus, exerts an approach action, i.e. an action to force the respective blade against the rail-stock.
  • an approach action i.e. an action to force the respective blade against the rail-stock.
  • the blade of the rod T1 would override, whereby the notches of the respective operating rods and checking rods would not be in line with the transverse locking member 23 and the latter would be prevented from effecting its point-locking stroke and actuating of the check device. Therefore, the action of the spring 21 makes the closing blade exert a pre-established pressure against the rail-stock, thus overcoming small obstacles which might be interposed between the blade and rail-stock and permitting to ascertain the presence and exact positioning of the rail-stock.
  • the elastic coupling between the slide 3 and operating rods T1, T2 aims to prevent any damage to the motor and members of the kinematic chain in case of an obstacle or strong resistance opposing to the movement of the blades.
  • the pins 11 and 11' will pursue exerting a corresponding push against the shaped plates 7 or 7'.
  • Said plates 7 or 7' therefore, displace their sliders 5 or 5' against the action of the spring 6 until the guide rollers 9 or 9' will reach the end of the slot wherein they slide, where a suitable shaping of the slot causes a downward rotation of the respective plates 7 or 7' about their pivots 8 or 8'.
  • the slide 3 is thus disconnected from the operating rods T1, T2 and may terminate its stroke so as to actuate the limit-switch device to cut off the power supply to the motor and pre-set the circuit for the reverse operation.
  • the restoration of the normal condition of the switch-points mechanism is obtained automatically by effecting the reverse operation.
  • the backward movement of the slide 3 permits the shaped plates 7 or 7', pushed upwards by suitable springs (not shown), to resume their original normal angular position, whereby restoring the elastic connection between the slide 3 and operating rods T1, T2.
  • the switch-points according to the invention is of the forcing-open type, whereby should said switch- points be engaged by a train from the heel and in a wrong position, the displacement of the blade assembly would be obtained with no damage to the members, either internal or external, of the switch-points mechanism.
  • the trailing action occurs as follows: the axle of the vehicle which engages the heel of the points in a wrong position will force the open blade and force it toward its respective rail-stock. Since the rod T1 of the now open blade is connected to the slide 3 through the elastic coupling device, the slide 3 is urged to move in the same direction as the open blade and respective operating rod T1.
  • connection between the slide 3 and worm-screw 2 is made irreversible by means of a stabilizing device (not shown) whereby the slide 3 cannot be driven by the rod T1.
  • the pin 11' solidary with the slide 3, which is unmovable in its position exerts a reactive force on the plate 7' which, through the slider 5', causes a compression of the spring 6.
  • the guide roller 9' therefore, moves along the slot of the plate 7' until it reaches the end of said slot where, as stated above, a suitable shaping urges the plate 7' downwards by pivoting it about its pivot 8.
  • the coupling member 4 is disengaged from the slide 3 and may slide, under the pushing action of the rod T2, as far as to actuated the limit-switch device and cut off the power supply to the motor.
  • the operating rod T1 connected to the coupling member 4 is, in turn, disconnected from the slide 3 and the switch-points frame may resume its operational movement with no damage to the components.
  • the slide 3 moves back and brings the shaped plate back to its original position and re-establishes the elastic coupling between the slide 3 and rod T1. Therefore, the capability of trailing the points affords the re-establishment of the normal operating conditions by means of a successive operative command, with no need of a local intervention.
  • the switchpoints mechanism according to the invention may be made uncapable of trailing either optionally under command or permanently.
  • the uncapability under command is effected by means of an electromagnet which is arranged within the container of the switchpoints mechanism and which, when not energized, latches the point-lock 23.
  • the permanent uncapability is obtained by means of a mechanical device, which, however, permits the rod connected to the open blade to move to such an extent as to cause the loss of the electrical positional check of the switchpoints, but not the loss of the point-lock capability.
