Definitions

  • the invention relates to a railway, tramway or the like turnout, of so-called English type according to the preamble of claim 1.
  • An English type turnout of this type is known from EP-1024988 ( WO99/020512 ).
  • This document discloses an English-type turnout in which the switch stand is provided in the form of a tie and is mounted in the railway line instead of a tie.
  • the turnout is of trailable type and has means that alternately change it from trailable to non-trailable. All mechanical parts for driving and locking/unlocking the switch points in the various thrown positions (so called point locking devices), as well as other control devices are held within the tie-like switch stand.
  • the English-type turnout comprises four points and is used when two tracks cross each other.
  • the two tracks have one pair of rails each, which cooperate with first and second pairs of points, one point of each of said first and second pairs of points being located in the middle of the turnout and cooperating with one of the innermost rails, whereas the other two points of the two pairs of points are located at the opposed outer areas of the turnout and cooperate with the outermost rail.
  • point displacement is applied to the two outer points of the two pairs of points only.
  • Each of the outer points is connected to an inner point by means of a rigid connecting rod.
  • the thrown position of the points is alternately assumed by one outer point of one of the two pairs of points and by the inner point of the other pair of points, which also determines which ones of the two points of the one and the other pairs have to be connected together.
  • the outer points pull along the inner points during their displacement and also, when lock devices are provided for locking the outer points in their thrown position against the associated outer rail, they also lock the inner point associated therewith, which has reached its thrown position against the associated inner rail.
  • the connecting rods are located below the tracks, in channel formed in the borrow for accommodating said rods, which is not protected at present.
  • these rods are an important and critical feature for proper operation of the turnout and, should one of these get broken, the corresponding inner point would be free to assume any position relative to the associated rail, as it would be disengaged from the point locking means and the point displacing means.
  • a first object of the present invention consists in making a turnout as described hereinbefore safer for railway traffic, particularly against any damage.
  • the invention solves this problem by providing a turnout as defined in the preamble of claim 1, which further comprises the characteristics of the characterizing part of claim 1.
  • a stand that accommodates the rods, which stand has exactly the same size as a tie, and which stand replaces a tie, allows the rods to be protected from any damage or obstacle to their free sliding motion, such as buildup of borrow, or any part of material falling into the rod channel and hence interfering with free rod motion.
  • the turnout has point lock/unlock means for locking/unlocking the points in and from their thrown positions also for the central points.
  • point lock/unlock means for locking/unlocking the points in and from their thrown positions also for the central points.
  • These means are provided in the central area of the switch stand and are shared by the two central points, sliders being provided for driving said central points, and cooperating with means for locking/unlocking the latter in and from the point thrown position, which means allow or prevent translation of said sliders, when one of the two central points reaches the closed or thrown position or when the turnout is operated to displace the points into the other closed or thrown position, respectively.
  • the lock/unlock means for the central points are also connected to means for transferring a point displacement drive generated by a motor, whereby the central points are pulled or pushed by the outer points not only through the connecting rods, but also through the common lock/unlock means, which are directly controlled by the driving motor, like the outer points.
  • first switch stand and the second stand for the connecting rods are formed with a modular construction.
  • the latter is particularly formed as described and shown in EP 1594732 .
  • the lock/unlock means for locking/unlocking the central points in and from the closed position are also modular and formed like said means for locking/unlocking the frog of a turnout, as described in EP 1594732 .
  • a further object of the invention is to provide a turnout of so-called English type with a construction in which the locking/unlocking, i.e. point locking and displacement features for the central points are independent from those for the outer points, to prevent any damage or malfunction of the lock/unlock means for the outer points and/or the connecting rods that connect them to the corresponding central point, from causing failure of the central points to be locked in position or connected to the displacing means.
  • the invention solves this problem by the characteristics of claim 1.
  • lock/unlock means for the central points that are shared by the two central points and independent of those of the outer points, and that are also dynamically connected to the motorized point displacing means, affords control and monitoring of the central points independent of the outer points, and also, in addition to the rigid connecting rods between the inner, i.e. central and the outer points, provides a double safety feature for the outer points and the inner points which always ensures the possibility of displacing all the points and locking them in the closed position even when one of the lock/unlock means or the transfer of the point displacing drive is damaged, regardless of whether this involves said means for the inner points or those for the outer points.
  • the invention also has the object to provide a turnout of the English type that has a efficient and cost-effective construction and allows easy replacement of the operating units.
  • the modular construction helps to maintain low fabrication costs and speeds up and facilitates maintenance, replacement of damaged parts and repair of these parts.
  • Figure 1 shows a prior art turnout of so-called English type, which is provided at crossings and has four points.
  • Such turnout is described in greater detail in EP 1024987 and EP 1219521 which disclose particular embodiments thereof and shall be deemed to be part hereof for all technically compatible parts, concerning the construction of means and devices that can be used in combination with the guiding principle of the present invention.
  • two tracks are provided with the rails B1, B1' and B2, B2' cooperating with the points A1, A1' and A2, A2' respectively.
  • a switch stand 1 having a shape and a size substantially corresponding to those of a rail tie houses the means for displacing the points A1, A1' and A2, A2'.
  • the rails B1, B1', B2, B2' are secured to the tie-like switch stand 1.
  • the four points A1, A1', A2, A2' cooperate in pairs with the rails B1, B1', B2, B2' of a track and are operated together.
  • the switch stand as described in the above documents uses a single drive for the four points A1, A1', A2, A2' whereas, the outermost points A1, A2' only are provided with means for removably locking them in the thrown position against the associated rail B1, B2'.
  • the inner points A1', A2 are locked in the thrown position by a rigid connection 55, e.g. a connecting rod for connection to the outer point A1, A2', which assumes the thrown position with the innermost one A2, A1'.
  • two tracks cross each other and have a pair of rails B1, B1', B2, B2' cooperating with a first and a second pair of points A1, A1' and A2, A2' respectively.
  • a point A2, A1' respectively of each of said first and second pairs of points is located in the central area of the turnout and the other two points A1, A2' of the two pairs of points are located at the opposed outer areas of the turnout.
  • the mechanical connecting rods connect each of the points A2 and A1' in the central area of the turnout, belonging to the first and second pairs of points respectively with one of the outer points A1 and A2' of the other pair of points, which outer point assumes the closed position with the corresponding point in the central area of the stand.
  • the points are alternately moved to the closed position, i.e. to the thrown position of said point A1, A2, A1', A2' against an associated rail B1, B1', B2, B2', one of the two points of each of said two pairs are driven by common means for combined point displacement.
  • the closed position also known as thrown position, is simultaneously reached by the two points A1, A2; A1', A2', one of which is a point of the first pair of points A1, A1', while the other is a point of the second pair of points A2, A2'.
  • One of the points in said closed position is always a point A1, A2' located in the outer area of the turnout, whereas the other point A2, A1' is a point located in the inner area of the turnout.
  • Prior art turnouts further have lock/unlock means which only directly operate on the drive means for the outer points of said two pairs of points. These means are located at the rail associated with the corresponding outer point and lock the outer points A1, A2' in their respective closed position. The inner points are moved and locked in their closed position by the connecting rods 55 only, which rigidly connect each of them to a corresponding outer point, i.e. the one that assumes the closed position with the inner point with which it is connected.
  • Figures 2 to 25 show an English turnout of the present invention. Concerning construction, this turnout has substantially the same functional parts and substantially the same configuration as the prior art turnout. However, as shown in the figures, in accordance with a first advantageous characteristic, a housing stand is also provided for the connecting rods 55.
  • the connecting rods 55 are fastened to the ends of their respective points A1, A2, A1', A2', whereas such ends of the points are aligned with the central longitudinal axis of a railway tie.
  • the housing stand 1' is provided as a replacement of the tie and acts both as a tie and as a housing compartment, similar to the switch stand 1, which acts both as a tie and as a housing for the point displacing means and the other operating units required for operation of the turnout.
  • the ends of the points are also advantageously provided at a distance from the central longitudinal axis of the switch stand 1 that houses the point displacing means and the other operating units of the turnout that is equal to the center-to-center distance of the ties, whereby the switch stand 1 and the housing stand 1' for the connecting rods 55 replace two parallel adjacent ties.
  • the fastening position of the connecting rods may also not be at the ends of the points, as the connecting rods may be also fastened to the points at an intermediate location on the side of the switch stand 1 opposite to the point ends.
  • the rods will substantially coincide with the central longitudinal axis of the tie, for the housing stand to be used both as a housing for the connecting rods 55 and as a tie.
  • the switch stand 1 is closer to the point ends than to the rod housing stand.
  • the connecting rods 55 are driven by rigid brackets below the bottom plane of the rails and at such a depth that said rods fall with their longitudinal axis and their displacement stroke within the cross section of the tie and hence of the housing stand 1'.
  • the brackets 155 for fastening the connecting rods to the points form downward vertical extensions at whose ends the connecting rod is connected.
  • the connecting rod may have angled ends radially extending from its longitudinal axis and having such a length as to maintain the rod section oriented horizontal or parallel to the displacement stroke thereof, in the cross section of the housing stand 1, obviously when the latter is being operated.
  • the rails are fastened to the box of the switch stand 1 and to the housing stand 1' in a similar manner.
  • fastening arrangements may be provided, including those described in EP 1024987 , EP 1219521 and EP1594732 .
  • the fastening arrangement as described in EP1594732 will be used in this example:
  • the stands 1, 1' have a vertical threaded pin 20 in their opposed end areas external to the corresponding outer rail A1, A2', the fastening base 121 of a rail locking element 21 being fitted on said pin.
  • the locking element 21 has a vertical extension 221 which is supported in a cantilever fashion towards the corresponding rail 4, 5.
  • the vertical extension 221 has a wedge shape, corresponding to the flared I shape of the rail.
  • Said extension may be adapted to be secured by one or more threaded pins against the corresponding rail, in a position in which it is wedged in the flared recesses of the I section of the rail. This provides accurate, self-centering and clearance-free positioning.
  • a similar fastening arrangement is also provided for the inner rails B2, B1', although in this case the fastening means are smaller for space requirement reasons.
  • the switch stand 1 houses a drive motor M which, through a drive 10 that converts the rotary motion of the motor into a linear motor, drives in a sliding fashion the point pulling rods, which pulling rods are provided in combination with point locking means.
  • the latter consist of point locking means which lock the points against displacement applied thereon, and are operated as soon as a point reaches its closed position, i.e. its thrown position against the corresponding rail. If the motion to displace the point away from its thrown position against the rail so that the other point/s, previously not thrown, can be moved into said position, is applied by the motor and the drive, the locking means are switched to the idle position thanks to an overrun that generally controls the point pulling rods.
  • the lock/unlock means generally consist of hook-like means or latches which are moved into an active or inactive locking state according to the position of the point with which they are connected relative to the rail.
  • the displacement of the hook-like means or latches is controlled by cams that are displaced with the pulling rods and act upon said hook-like or latch means by displacing them, according to the position of the point and the stroke being run, from a position of engagement with a hook-receiving or retaining seat to a position of disengagement from said seat.
  • the point locking devices and the latches may have any construction whatever, for instance as described in any one of EP 1024987 , EP 1219521 and EP1594732 or of other types.
  • dedicated point locking means 141, 142, 143 are also provided for the inner points.
  • a common dedicated point pulling rod is provided for the inner points A2, A1', which pulling rod has automatic point displacement locking means which are triggered every time that one of the points reaches its closed position, irrespective of which inner point has reached said position.
  • the inner points are both unlocked and translated together when the displacement thereof is controlled by the motor.
  • both the switch stand 1 and the housing stand 1' have a modular construction, and that substantially identical elements are used to form identical parts, or parts having identical functions.
  • the example of the turnout as shown in Figures 2 to 25 relates to a particular embodiment in which the switch stand 1 with its operating units and the housing stand 1' with the point tip connecting rods, have a modular construction.

  • Such drive module is highlighted in gray in Figure 7 and separately in Figure 9 .
  • Particularly the coupling joint fastened to the shaft of the motor M can be opened and allows separation of the drive of the motor M.
  • the drive module consists of a drive that converts the rotary motion of the motor M into a linear translational motion directed along the longitudinal axis of the box 100 and the point displacement axis.

  • EP 1024987 , EP 1219521 and EP1594732 describe a few embodiments of such drive in greater detail.
  • the threaded drive actuating rod has a terminal 112 for removable coupling to the remaining operating parts that pull the points along their stroke, whereas the drive 110 has the joint part 113 connected to the corresponding part on the shaft of the motor M.
