Definitions

  • the present invention has for an object the provision of an improved device for displacing a section of a railway track in its transverse plane and/or maintaining it there in fixed position, this device being characterized in that it comprises a tool-carrying frame adapted to cooperate with the track, two uprights, a connecting bar between these uprights, these four elements being hinged one to the other to form, through their points of articulation, a deformable quadrilateral, at least one shifting jack connecting two of the four cited elements and disposed to act obliquely on these four elements, in order to deform this quadrilateral, a supporting member for each upright and on which the upright is adapted to slide and, for each upright, a hoisting jack to make these two elements slide one with respect to the other.
  • FIGS. 1 to 3 show a front view of each of these three examples, in section transverse to the track, the same reference numbers indicating the elements which are placed symmetrically relative to the axis of the track;
  • FIG. 4 is a diagram of a hydraulic circuit usable for the three embodiments.
  • FIG. 5 is a detail view relative to a modification of FIG. 2.
  • FIG. 1 are two rails 1 connected by a sleeper 2 resting on the ballast 3.
  • a frame 4 and a connecting bar 5, both in the shape of horizontal girders, are hinged through their ends 6, 7 to two uprights 8 which are each provided with two guides 9 and 10 of rectangular section in each of which may slide, but not pivot, a supporting member 11.
  • a hydraulic or hoisting jack which is constituted by a cylinder 12, pivoted to uprights 8 by pin 13, and in which may slide a piston 14 with a rod 15 pivoted on a base 16 integral with supporting member 11.
  • the jack is free of any strain through its axis.
  • the bases 16 bear on the part of the ballast located between two sleepers but are beyond the same.
  • a third jack a so-called shifting jack, of the same kind as the preceding one is constituted by a cylinder 17 in which may slide a piston 18 with a rod 19. This jack is hinged on the one hand by pin 20 to the frame 4 and on the other hand by pin 21 to the bar 5.
  • the frame 4 supports a track gripper, with automatic centering relative to the axis of the track and which includes two hooks 22 pivoted by pins 23 on frame 4 and provided with noses 24 acting in opposite directions which may engage under the heads of the corresponding rails 1.
  • the automatic centering of the track relative to frame 4 is obtained by the bar 25, a so-called synchronism bar, which connects the two hooks 22 by the pivots 26 and 27 placed at a substantially equal distance from the two pivots 23, but located above and below one another.
  • a fourth jack a so-called gripper jack, of the same type as the preceding ones, horizontal and pivoting on pins 28 on each of the hooks 22.
  • In its cylinder 29 may slide a piston 30 with a rod 31.
  • FIG. 1 clearly shows that the track is thus fixed to the frame 4.
  • frame 4 and bar 5 are horizontal and the two uprights 8 are vertical so that the four hinges 6 and 7 are at the corners of a rectangle. This shape is maintained due to the immobilization of the shifting jack in the desired position.
  • the rigid frame thus obtained is supported by the two hoisting jacks 12, blocked in the correct position.
  • the track may be inclined transversely by any desired amount, in one direction or the other, by correctly modifying the length of each hoisting jack.
  • the device may also be employed for shifting alone. It is then highly desirable not to lift the track because it is then nearly impossible to lower it again in view of the stones which slip under the sleepers.
  • the bases 16 may be provided with cramps or be replaced by pickaxes which may due to the hoisting jacks be sunk into the ballast without causing the raising of the track.
  • the track may be propped, for example with ballast, or laid on the ground following the desired lay out, etc. according to the well known techniques of using hoisting-propping devices, hoistingshifting devices, etc.
  • FIG. 2 there is reproduced with the same references a part of the elements shown in FIG. 1.
  • the two cylinders 12 which directly form the aforementioned uprights 8 so that the aforesaid sliding members 11 are here constituted by the pistons 14 with their rods 15 on bases 16.
  • the shifting jack has its hinge 21 connected to one of the hinges 7 of the parallelogram. The operation of the whole is identical to that of the preceding embodiment. It must be emphasized that the rods 15 must be sufficiently strong to be able to absorb the bending stresses which they have to support.
  • FIG. 3 shows also with the same references a part of the elements of FIG. 1.
  • the aforesaid bar 5 is here a girder disposed on the front of a vehicle which serves as a support for the device.
  • the two hoisting jacks serve as extensible uprights and are set up as traction jacks so that their cylinder 12 is hinged on pins 7 on bar 5 so that their rod 15 is pivoted at pins 6 on frame 4.
  • the shifting jack is hinged through its cylinder on bar 5 and through its rod on frame 4. Its operation, so that of the gripper jack, is unchanged. It is noted that these three jacks are free of any parasite bending stress.
  • the four hinges 6 and 7 are located in the drawing at the angles of a symmetrical trapezium with bases parallel to the plane of the track, and it is quite obvious that one may still displace at will the section of track along its plane by suitably actuating the jacks.
  • the two parallel sides of the trapezium are of constant length while the oblique sides are of variable length according to the amount of extension of the hoisting jacks.
  • FIG. 4 one has shown with their references the four jacks which form part of the hydraulic circuit.
  • the said jacks are fed from a common supply of oil under pressure, which comprises a tank 32 in which a pump 33 sucks up oil through the duct 34 and discharges it into the duct 35 under a pressure limited by the safety valve 36 which sends back the excess oil through the duct 37 into the tank 32.
  • Duct 35 feeds four identical distributors 38 from which the oil may escape by the collector duct 39 which returns it to tank 32.
  • Each of these distributors 38 is connected on the one hand by a duct 40 to the large chamber 41 and on the other hand by a duct 42 to the annular chamber 43, provided between the cylinder and piston of each of the similar four jacks.
  • the arrangement of the jack-distributors being identical for the four groups, it is sufiicient to describe the operation of one of them.
  • each jack In the position shown, each jack is blocked by the oil which it contains and which cannot escape from chambers 41 and 43 by any of the ducts 40 and 42 themselves obviously cut off from any communication by the slide 44. All the flow discharged by the pump flows through ducts 36 and 37 into tank 32. If one of the slides 44 is pivoted through one eighth of a revolution in a counter-clockwise direction, communication is established between ducts 35 and 40 and between ducts 42 and 39 so that chamber 41 is under pressure and chamber 43 is under discharge. The jack thusly controlled lengthen-s until its movement is stopped by returning the slide 44 to its original position.
  • Each of the slides 44 is integral with a control handle 45 which is placed to provide an available control for the operator who wishes to actuate one or the other of the jacks.
  • a control handle 45 which is placed to provide an available control for the operator who wishes to actuate one or the other of the jacks.
  • a device for displacing a section of railway track comprising a tool-carrying frame means adapted to cooperate with the track, two upright means, a connecting bar means between said upright means, pivot means connecting said frame and upright and bar means to form a deformable quadrilateral, and at least one shifting jack connecting two of said frame and upright and bar means and disposed to act obliquely. on the thusly connected means to deform said quadrilateral, each said upright means including a supporting member and a hoisting jack for the raising and lowering of the upright means.
  • a device wherein said pivot means are arranged such that the four sides of said quadrilateral have a constant length.
  • a device wherein said pivot means are arranged such that two sides of said quadrilateral are formed by the frame means and the connecting bar means and are of constant length, the other two sides being of variable length.
  • a device wherein the sides of variable length are formed by the hoisting jacks.
  • each of the upright means is constituted by the cylinder of its hoisting jack of which the piston-rod constitutes the corresponding supporting member.
  • connecting bar means constitutes a support on which bear the hoisting jacks.
  • a device wherein the supporting members are adapted to bear against the frame of a railway vehicle.
  • each hoisting jack includes a cylinder-piston and rod combination, said cylinder including a hinge near the connection of the rod and the piston, the axis of said hinge intersecting the axis of the cylinder.
  • a device wherein the hoisting jacks include cylinders and the connecting bar means is hinged on the cylinders of the hoisting jacks towards the middle of the length of said cylinders.
  • a device according to claim 1, wherein the jacks are disposed in a common pressure-fluid circuit.
