Definitions

  • the present invention relates to a device for adjusting the intermediate distance of two end pieces of rails to be connected.
  • the intermediate distance between the two ends must first be adjusted in order to then allow the actual connection operation to be carried out, which can be carried out by welding or by fitting fishplates.
  • This adjustment operation can consist either in decreasing or increasing the intermediate distance between the two ends depending in particular on the outside temperature conditions which can cause the rails to expand or contract.
  • intermediate distance adjustment devices which comprise two frames capable of respectively enclosing the two rails, the intermediate distance of their ends of which must be adjusted, and jacks articulated to the two frames to bring the two closer or further away. frames and consequently respectively the reduction or the increase of the intermediate distance.
  • a device for adjusting the intermediate distance of two such rail ends is known from patent application GB-A-2 000 829.
  • This known device comprises means capable of causing the displacement of a movable frame relative to a fixed frame and means capable of making the rails integral with the frames.
  • the main object of the present invention is to provide a device for adjusting the intermediate distance of two end pieces of rails to be connected which can be adapted, without disassembly, both to an adjustment operation by increasing the intermediate distance and to a adjustment operation by decreasing the intermediate distance.
  • Another object of the invention is to provide an adjustment device capable of developing the power necessary for adjustment operations under the most severe conditions.
  • Another object of the invention is to provide a wagon movable on a railroad track and equipped with at least one and preferably with two handling devices able to each move an adjustment device according to the invention to allow simultaneous effecting of two intermediate distance adjustment operations on the two rows of rails of a railroad track.
  • the present invention provides a device for adjusting the intermediate distance of two end pieces of rails to be connected, characterized in that it comprises a single fixed frame capable of enclosing one of the two rails, two parallel bars one end of which is integral with the fixed frame, two movable frames capable of sliding independently over a limited distance on the parallel bars in the vicinity of their other end and capable of enclosing the other rail, jacks capable of causing the relative displacement of the movable frames on the parallel bars, immobilization means able to immobilize any of the movable frames on the parallel bars and allow the sliding of the other movable frame on the parallel bars when the jacks are actuated, the movable frame sliding and the fixed frame being clamped on their respective rails to reduce or increase the intermediate distance of the two ends depending on whether the sliding movable frame is the one closest or respectively farthest from the fixed frame.
  • the immobilization means consist of two spacers each affecting a U-shaped section and capable of covering each of one of the two parallel bars, that is to say between the movable frame furthest from the fixed frame and an end stop of the bar, ie between the movable frame closest to the fixed frame and an intermediate stop of the bar.
  • the fixed frame comprises a rail passage tunnel flaring at its two ends to allow two clamping corners to be placed between the two sides of the core of the rail to be clamped and the end of the tunnel which is the closest or the furthest from the movable frames, depending on whether it is necessary to decrease or respectively to increase the intermediate distance of the two rail ends.
  • each movable frame has a rail passage tunnel flared towards its end opposite to that closest to the other movable frame to allow two clamping corners to be placed between the two sides of the core of the rail to be tightened and the sliding mobile block tunnel.
  • FIG. 1 shows an adjustment device 10 according to the invention applied to a left rail 12 and a right rail 14, the intermediate distance of their ends of which must be adjusted before carrying out the connection operation properly.
  • the device 10 is constituted by a fixed frame 16 affecting, in view of the end, the general shape of a semicircle (cf. FIG. 2).
  • the fixed frame 16 comprises a central block 18 in the shape of a U open towards the bottom defining a passage tunnel for the rail 14.
  • This central block 18 is connected to a semi-circular external frame 20 by means of reinforcing pieces such as 22.
  • the frame 16 comprises two rings 24 and 26 respectively intended for the attachment of two parallel bars.
  • loops 28 and 30 intended to be placed parallel to the direction of the rails 12 and 14.
  • the ends of the bars 28 and 30 not subject to the fixed frame 16 are used for fixing rod 32 and 34 of circular section.
  • the rods 32 and 34 are located in the respective extension of the bars 28 and 30 and are parallel to each other.
  • the rods 32 and 34 constitute sliding bars, the sliding distance of which is limited by end stops 36 and 38 and by intermediate stops 40 and 42.
  • the device further comprises two movable frames 44 and 46 able to slide on the rods 32 and 34 between the stops 36 and 40 and 38 and 42.
  • the movable frames 44 and 46 are identical and have the general shape of a semicircle similar to the general shape of the fixed frame 16.
  • the movable frames 44 and 46 each define a passage tunnel 48 and a passage tunnel 50 respectively for the rail 12.
  • the frames 44 and 46 can be moved relatively relative to each other by means of two double-acting hydraulic cylinders 52 and 54 whose bodies are fixed to the movable frame 44 and whose respective rods 56 and 58 pass through the frames 44 and 46 and are subject to the frame 46.
  • the jacks 52 and 54 are arranged parallel to the rods 32 and 34 and consequently to the parallel bars 28 and 30 to allow the relative movement of the frames 44 and 46 by sliding on the rods 32 and 34.
  • the device 10 also includes immobilization means capable of immobilizing any one of the movable frames 44 and 46 on the rods 32 and 34 and thus allowing the sliding of the other movable frame under the action of the jacks 36 and 38.
  • These immobilization means are constituted by two spacers 60 and 62 each affecting a U-shaped section and capable of covering the two rods 32 and 34 respectively.
  • the spacers 60 and 62 can be placed either between the frame 44, which is the farthest of the fixed frame 16, and the end stops 36 and 38 (cf. upper part of Figure 1), that is to say between the frame 46, which is closest to the fixed frame 16, and the intermediate stops 40 and 42 (cf. . lower part of Figure 1).
  • the intermediate stops 40 and 42 cf. . lower part of Figure 1
  • the central block 18 of the fixed frame 16 defines a rail passage tunnel which widens towards its two ends to allow two clamping corners to be put in place between the two sides of the rail core 14 and the end of the tunnel which is the closest or the furthest from the movable frames 44 and 46 depending on whether it is respectively necessary to decrease or increase the intermediate distance of the two ends.
  • tunnels 48 and 50 of the movable frames 44 and 46 are flared towards their end opposite to that closest to the other movable frame to allow two clamping corners to be placed between the two sides of the web of the rail 12 to be clamped and the tunnel of the sliding mobile unit.
  • two clamping corners such 64 are placed between the two sides of the web of the rail 14 and the tunnel of the frame 18, towards the end of the tunnel which is closest to the movable frames 44 and 46 and, likewise, two clamping corners 66 are placed between the two sides of the web of the rail 12 and the tunnel 50 of the movable frame 46.
  • the jacks 52 and 54 are then actuated so as to cause the displacement of the movable frame 46 in the direction of the fixed frame 16.
  • This displacement causes blocking corners 66 and 64 between the rails 12 and 14 and the frames 46 and 16 and consequently the approximation of the ends of the rails 12 and 14 in the direction of the arrows F.
  • two clamping corners 68 are placed between the two sides of the web of the rail 14 and the tunnel of the fixed frame 16 towards the end of the tunnel which is furthest from the movable frames 44 and 46 and two clamping corners 70 are placed between the two sides of the web of the rail 12 and the tunnel 48 of the movable frame 44.
  • This displacement causes the corners 68 and 70 to be blocked and consequently the two ends to be separated in the direction of the arrows G.
  • Figure 2 shows how one of the two corners 68 is interposed between the U-shaped block 18 and one of the sides of the web of the rail 14.
  • the jacks 52 and 54 must be retracted to bring the movable frame which has slid back against the movable frame which had been immobilized by the spacers 60 and 62.
  • the invention provides that the two spacers 60 and 62 are each provided with two end flanges capable of securing each spacer with the movable immobilized frame and the intermediate stop or the end stop of the corresponding rod .
