Definitions

  • the invention relates to a switch machine, according to the preamble of claim 1, for railway and tramway switches or the like, having a housing case for its operating units of the same size as a tie and adapted to be installed like a tie.
  • Switch machines of this type are known, for example from EP1594732B1 , and widely used and generally comprise a metal case, e.g. formed by iron casting or structural steelwork, with sheet bending, welding, etc.
  • Prior art switch machines of this type usually have a protective coating, consisting of plain paint.
  • Such switch machines have the drawback of having railway ballast interface surface characteristics that cause ballast to tend to move due to the vibrations induced by running trains.
  • the ballast may be significantly displaced and create gaps below and around the switch machine, thereby affecting rail stability and support, and requiring earthing up of the ballast.
  • the present invention has the purpose of obviating the above drawbacks of prior art switch machines with a switch machine as described above, whose outer surface further has a covering on at least part of the case, which covering consists of a material, comprising an epoxy resin, having railway ballast interface surface characteristics similar to concrete.
  • said surface characteristics are roughness, friction coefficient and hardness.
  • said material has a hardness ranging from 60 to 100 Shore, preferably from 70 to 85 Shore, particularly of 75 Shore.
  • said epoxy resin is filled with ceramic beads.
  • said material has a thickness ranging from 2 to 10 mm, preferably from 4 to 8 mm, preferably of 6 mm.
  • the covering with the above mentioned properties imparts concrete-like ballast interface characteristics and overcomes the above mentioned ballast displacement problems.
  • the covering ensures an excellent protection of the switch machine, so that the expected life of the switch machine may be increased to 30 years.
  • the covering may be applied to the outer surface of the case in any manner whatever.
  • said material is applied to said outer covering surface by manual and/or automatic spreading.
  • said material is applied to said outer surface of the case by embedment, i.e. by placing said case in a negative mold that has an inner mold surface mating with said outer surface of the case, said negative mold being previously filled with said material in a fluid phase.
  • Such second application method is particularly advantageous in many applications, in which the construction of molds is economically supported by great numbers of uses thereof.
  • FIGS 1 to 4 show the switch machine 1, which comprises a switch point shifting actuator, particularly a hydraulic cylinder 2.
  • the actuator 2 displaces the points, using actuation drive means, between two limit positions, one of which positions is called normal position and the other of said two positions is called reverse position, and in which positions each of the two points is thrown or open relative to the closest rail, in alternation with the other point.
  • the shifting stroke of the points between said two positions having a predetermined length matches a given actuation stroke of the actuator 2.
  • Lock/unlock means are further provided for locking/unlocking said points in one of said limit positions, referred to as switch point lock means, which switch point lock means are driven into their unlocking state by said actuator 2, through an initial actuation overstroke, whose end coincides with the point unlocked state, and with the time at which said point shifting actuation stroke starts, whereas the end of the point shifting actuation stroke, in which one of the points is moved from an open position to a thrown position relative to the closest rail and the other point is moved from a thrown position to an open position relative to the closest rail, coincides with the time at which a final actuation overstroke, through which said actuator 2 drives said point locking means into their locking state.
  • the switch machine 1 and at least the actuator 2 and said actuation drive means and at least said switch point lock means have a modular construction.
  • Said switch point lock means consist of two point pulling and locking modules 30 and 31, which are located at the opposite ends of said hydraulic cylinder 2.
  • Each point pulling and locking module has its own case or frame, which case or frame has means for fastening it in predetermined positions, cooperating with coincident fastener means, in predetermined positions on the tie-like box module 100 in which the switch machine 1 is housed.
  • the tie-like box module 100 consists of a C or ⁇ -shaped section, open at its top as a channel and closed by one or more covers.
  • the tie-like box module 100 has lateral longitudinal fins 101 having holes in predetermined positions for receiving cover elements and/or lateral flanges for fastening operating modules such as the point pulling and locking modules 30 and 31.
  • the point pulling and locking modules 30 and 31 also have holes at predetermined positions coinciding with the holes of the tie-like box module 100 and are mounted in a predetermined position with reference to the tie-like box module using fastener means.
  • end heads 130 that may also be removably fastened or possibly welded.
  • a portion of the cover of the tie-like box module 100 is formed by the upper cover of the modules, whereas the portions of the tie-like box module 100 that are open at their top as they are not filled by operating units are closed by a plurality of cover elements having the same size as said open or exposed parts.
  • cover elements are referenced 260, 261 and 262.
  • One end of the switch machine 1 is designed for connection with fluid supply lines and/or power lines for any electronic diagnostic system or the like.
  • Each of the point pulling and locking modules 30 and 31 has a pulling rod 144 which is dynamically connected to pulling sliders 145 that project out of an upper fastening plate 146.
  • the fastening plate 146 has lateral holes for fixation to the lateral longitudinal fins 101 of the tie-like box module 100 and also forms the closing cover of said tie-like box module 100 when the pulling and locking module is mounted to the tie-like box module itself.
  • the pulling sliders 145 have a positive geometry mating with the negative seat in the brackets for connection to the points.
  • the pulling rod 144 has a removable terminal for connection to the actuator 2 or to further actuation drive means.
  • Means are further provided for adjusting the actuation stroke exerted by the actuator 2, which operate to cause the actuator 2 to exert a first predetermined actuation force during the initial actuation overstroke to unlock said point switch lock means, a second predetermined actuation force during said point shifting actuation stroke and a third predetermined actuation stroke during the final actuation overstroke to lock the point lock means.
  • the actuator 2 may consist of any kind of motor, such as an electric motor and a kinematic drive chain, which kinematic drive chain may be of any type and consist, for instance, of a screw-and-nut or recirculating-ball assembly.
  • the actuation force exerted by the actuator 2 may be controlled by setting the force to be generated by the motor.
  • said kinematic drive chain may change the drive ratio according to the stroke that has been run: a first drive ratio is used for the initial actuation overstroke, a second drive ratio is used for the point shifting actuation stroke, and a third drive ratio is used for the final actuation overstroke.
  • the actuator 2 is a hydraulic actuator, particularly a hydraulic cylinder 2, which is connected to at least one delivery branch and at least one return branch of a closed hydraulic fluid circulation circuit.
  • the means for adjusting the actuation force exerted by the actuator 2 consist of means for setting the fluid delivery to the actuator 2, particularly comprising at least one adjustable flow pump.
  • the pump may be a positive-displacement pump controlled at a variable speed and having a predetermined fixed displacement.
  • positive-displacement pump is intended to designate a pump having a suction/compression chamber of predetermined volume, which changes fluid delivery according to the speed of actuation of a suction/compression member.
  • a particular positive-displacement pump is the piston or gear pump.
  • the volume of pressure fluid that can be delivered per unit of time is determined by the displacement and number of suction/compression strokes of the piston.
  • other types of pumps may be considered as positive-displacement pumps according to the definition as used herein, such as rotor pumps and/or pumps having suction/compression members based on the Wankel engine principle, in which the suction/compression chamber has a fixed and predetermined volume.
  • two or three or more pumps with different displacements may be provided, one or more of which are designed to be alternately and specially driven for actuating a particular operating step of the switch machine 1.
  • the use of multiple positive-displacement pumps is generally disclosed in EP 2192020 .
  • said force adjustment means consist of the actuator 2 itself.
  • the actuator 2 consists of a hydraulic cylinder 2 which comprises at least one pushing or pulling rod 20 adapted to be connected to one or both of said points and to be displaced from a minimum-extension position to a maximum-extension position.
  • the hydraulic cylinder 2 is a double acting cylinder, having two supply inlets, each of said supply inlets being adapted to be alternately connected to the delivery of the fluid circuit.
  • the rod 20 extends beyond both end walls of the hydraulic cylinder 20 and can be displaced from a position in which one part is in the minimum-extension state and the opposite part is in the maximum-extension state to a position in which the first part is in the maximum-extension state and the opposite part is in the minimum-extension state.
  • the ends of the rod 20 are removably connected to the pulling rods 144 of the point pulling and locking modules 30 and 31.
  • the displacement of the rod 20 drives the initial actuation overstroke, the point shifting actuation stroke and the final actuation overstroke, as shown in Figures 10a to 10d .
  • the hydraulic cylinder 2 is so designed that, given a pressure of the fluid, it exerts said first predetermined actuation force along the length of displacement of the rod 20 that corresponds to the initial actuation overstroke, said second predetermined actuation force along the length of displacement of the rod 20 that corresponds to the point shifting actuation stroke, and said third predetermined actuation force along the length of displacement of the rod 20 that corresponds to the final actuation overstroke.
  • the hydraulic cylinder 2 comprises an outer cylinder 21 and an inner cylinder 22, the outside diameter of the inner cylinder 22 being substantially equal to the inside diameter of the outer cylinder 21, the height of the inner cylinder 22 being smaller than the height of the outer cylinder 21 and the inner cylinder 22 being disposed coaxially inside the outer cylinder 21.
  • the inner cylinder 22 is displaceable in a fluid-tight manner in the outer cylinder 21 between two end positions defined by the inner extension of the outer cylinder 21.
  • a piston 23 is further provided in the inner cylinder, which is connected to the rod 20 and is displaceable between two end positions defined by the inner extension of the inner cylinder 22.
  • the rod 20 is adapted to extend through openings formed in the head surfaces of the inner cylinder 22 and the head surfaces of the outer cylinder 21.
  • the piston 23 has a fluid-tight connection with the inner cylinder 22 which in turn has a fluid-tight connection with the outer cylinder 21.
  • the piston 23 is coupled to the rod 20 in a central position thereof, to define two opposite parts of the rod 20, which extend through the heads 322 and 323 of the inner cylinder 22 and are guided in a fluid-tight manner in the heads 320 and 321 of the outer cylinder 21.
  • the passage from the inner cylinder to the delivery or return of the actuator 2 may occur in various manners.
  • such passage particularly occurs through radial fluid supply/discharge openings or passages 37, 38, at the two heads 320 and 321 of the outer cylinder respectively.
  • the cylinder has two fluid supply/discharge openings 37 formed in the first head 320, and two fluid supply/discharge openings 38 formed in the second head 321, to be used if multiple actuators are connected in parallel, so that, for instance, during fluid supply, the fluid coming from an upstream actuator in the supply line enters a first opening and exits a second opening to supply a downstream actuator in the supply line.
  • the pressure fluid is delivered to all the actuators.
  • the same principle applies to the fluid outlet of the cylinder.
  • a single fluid supply/discharge opening 37 and single fluid supply/discharge opening 38 may be also alternatively provided, with the provision of T-fittings to create parallel supply branches for each actuator 2.
  • the fluid supply/discharge openings 37 communicate with a radial opening 132 in the head 320, which is designed to communicate with the interior of the outer cylinder 22 through an annular slot 33 between the through rod 20 and the head 320.
  • An annular slot 34 is also provided between the head 322 and the rod 34, to put the chamber of the outer cylinder 21 in communication with the chamber of the inner cylinder 22.
  • the cylinder has the same structural parts in the opposite part, at the head 321.
  • the head 322 abuts against the corresponding head 320 and the piston 23 is at the head 322.
  • the supply fluid flows through the radial opening 132 and through the annular slot 33 thereby causing a pressure increase.
  • the fluid exerts a force on the head surface 322 of the inner cylinder 22 facing toward the chamber of the outer cylinder 21, which force is greater than the force exerted on the piston 23 through the annular slot 34, as the head surface 322 of the inner cylinder 22 facing toward the chamber of the outer cylinder 21 is much larger than the surface of the piston 23 available to the fluid through the annular slot 34.
  • the fluid starts to fill the chamber of the outer cylinder 21, thereby pushing the inner cylinder 22 and hence the piston 23 toward the opposite head 321.
  • the inner cylinder 22 and the piston 23 are held in joined relation as they move by the limit stop abutment for the piston 23 on the head 322.
  • the pressure fluid starts to move the piston 23 in the inner cylinder 22 toward the head 323, thereby progressively filling the chamber of the inner cylinder 22 by flowing through the annular slot 34.
  • the fluid contained in the cylinder when such movement starts is simultaneously ejected from the return camber through the radial opening 132 that is also provided in the head 321.
  • the synchronous overstroke of the inner cylinder 22 and the piston 23 corresponds to the steps of Figures 9a, 9b and 9c , which show the passage from a first position in which the piston 23 is at the head 322 and the inner cylinder 22 is at the head 320 to a second position in which the piston 23 is still at the head 322 but the inner cylinder 22 abuts against its limit stop on the head 321 of the outer cylinder 21, thereby completing its movement.
  • the rod 20 has had, in this construction example, a total displacement of 50 mm.
  • the displacement of the piston 23 to the position as shown in Figure 9d corresponds to a switch point displacement of 115 mm, i.e. a total displacement of the stem 20 of 165 mm.
  • the hydraulic cylinder 2 is mounted in the switch machine 1 in joined relation with the tie-like box module 100 by means of two coupling elements 24 attached at the ends of the hydraulic cylinder 2 and adapted to be fixed to the bottom of the switch machine 1.
  • the hydraulic cylinder 2 also comprises a plurality of bars, preferably four, which couple together the two coupling elements 24 and prevent any relative translational and rotational movement of the two coupling elements 24, thereby ensuring firm fixation of the hydraulic cylinder to the switch machine 1 also during the operating steps thereof.
  • two or three or more hydraulic cylinders are provided, one or more of which are designed to be alternately and specially driven for actuating a particular operating step of the switch machine 1.
  • FIGS 10a to 10d are detail views of the switch point lock means, which comprise a pair of hammers 28 and 29 supported to swing in the horizontal plane to and from the side wall 316 of the case of the tie-like box module 100 and a slider 27 driven by the pulling rod 144.

  • One of the two opposed lugs 128, 129 cooperates with an associated latching recess 516, 616, formed in the corresponding vertical wall 316 of the point pulling and locking modules 30 and 31, for primary and secondary switch point locking actions.
  • the other of the two opposed lugs 228, 229 of the two hammers 28 and 29 cooperates with an associated abutment surface 227, 327 on the slider 27 to cause the slider 27 to pull or push the hammers 29 and 29 for coupling.
  • the slider 27 has a roller 39 on the side facing toward the hammers 29, 29, which adheres against a cam surface formed on an extension of said hammers 28, 29 and controls displacement thereof.

  • the T-shaped hammers 28, 29 are pivoted about a vertical axis at the end of the base stem 328, 329, which extends to a certain extent beyond the fulcrum in such a manner that the roller 39 cooperating with the cam track on said end portion of the base stem 329 beyond the fulcrum, may cause the hammers to swing toward the slider 27 and to a condition of disengagement thereof from the latching recesses 516, 616 in the side wall 316 of the tie-like box module 100.
  • the shape of the cam track on the base stems 328 and 329 of the hammers 28 and 29, formed by the side surfaces of said base stems facing toward the slider 27, the overall length of the two opposed lugs 128, 228 and 129, 229 and the inclination of the end sides are selected in such a manner that, when the hammers 28, 29 are in either engagement position, with the wall 316 or the slider 27, the other end surface of the opposed lug extends in a position of non-interference with the slider 27 or the wall 316.

  • the slider 27 may move to a certain extent in the direction of arrow D until the lug 229 of the hammer 29 cooperates with the abutment surface 327 of the slider 27. In this condition the slider 27 starts to exert a pulling force on the point operating rod on which the hammers 28 and 29 are pivotally fixed.
  • the roller 39 rolls along the cam-like edge of the base stem 328 of the hammer 28 and the cam-like edge of the base stem 329 of the hammer 29, and reaches an intermediate position therebetween, i.e. a position in which it adheres to the end portions of both base stems of the hammers 28, 29, thereby causing them to simultaneously swing to disengagement of the two hammers 28 and 29 from the recesses 516, 616 in the wall 316.
