Definitions

  • the present invention relates to a turnout base plate fastening structure.
  • a turnout has a structure in which a steel base plate 22 is fixed on a sleeper 21, a stock rail 23 is fixed on the base plate 22, and a tongue rail 24 provided adjacent to the stock rail 23 is adapted to slide rightward or leftward by means of a shunt (not shown) on the base plate 22.
  • a variety of rail fastening devices in the turnout for a rail track can be used, and two methods described below are commonly employed.
  • One method is a washer method in which a washer is fixed on the base plate such that its right and left positions are adjustable by means of a bolt and a base portion of the rail is pressed by an end of the washer, to thereby fasten the rail to the base plate.
  • a rail brace 31 having a substantially L-shaped side surface is fixed on a base plate 33 such that its right and left positions are adjustable by means of a bolt 32, and an upper end portion of the rail brace 31 and an L-shaped curved portion 37 of the rail brace 31 are adapted to abut against an upper side portion 35 or chin portion 36 of a stock rail 34 and an upper surface of the base portion 38 of the rail 34, respectively, to thereby fasten the rail 34 to the base plate 33, thus preventing the tilting of the rail 34 (see Japanese Utility Model Publication No. Hei 7-32563.)
  • the base plate in order to fix the rail 34 shown in FIG. 9 on the base plate 33 and prevent unnatural force from being generated, it is preferable to place the base plate on the sleeper such that the fixed rail 34, positioned in a rail fixing recess 39 on the base plate 33, and a fixing recess 40 of the rail brace 31 are parallel with each other or one is slightly inclined with respect to the other (the fixing recess 40 is inclined with respect to the rail fixing recess 39).
  • the turnout comprises, as major components, a point section 41, a lead section 42, a crossing section 43, and a guard section 44, as shown in FIG. 10.
  • rails 46 are mounted on sleepers 45 with a successively varying positional relationship.
  • the rails 46 and the sleepers 45 are not at right angles with each other, and the crossing angle is also successively changing.
  • the length of the sleeper also must be changed according to where it is positioned.
  • FIGS. 12A and 12B an anchor 62 or 63 protruding from a lower portion of a base plate fastening device 61 is inserted into a PC sleeper 64 and secured thereto.
  • the PC sleepers are preferable in an ordinary rail section using a great number of sleepers having the same configuration because they are manufactured at low cost.
  • many steel rods 65 or piano wires 66 for reinforcement are embedded in the PC sleeper 64.
  • At least the preferred embodiments of the present invention are directed to solving the above-described problem of the prior art, and an object of the preferred embodiments of the present invention is to provide a turnout base plate fastening structure which reduces the number of types of base plate, PC sleepers, or steel sleepers.
  • a turnout base plate fastening structure in which the base plate is fixed on a sleeper by a base plate fastening device and a rail is fastened to the base plate by a rail fastening device, and the base plate has a rail fastening device fixing recess, characterised in that each of the end faces of the base plate in a longitudinal direction thereof is formed as a curved surface formed by a circular arc of a circle made with a centre of the base plate as a centre of the circle, and a surface of the base plate fastening device is formed such that it abuts against the curved surface of the base plate and is a curved surface corresponding to the curved surface of the base plate.
  • base plates having the same configuration capable of maintaining the positional relationship between the rail in the longitudinal direction thereof and the rail fastening device fixing recess are prepared for.
  • the base plate fastening devices are placed at different positions in the longitudinal direction of the sleepers but at the same positions in the lateral (width) direction thereof such that centres of the devices match corresponding centres of the sleepers.
  • the curved surfaces formed by the circular arc of the circle (circular-arc surfaces) at both ends of the base plate are rotated by a predetermined angle along the circular-arc surfaces of the base plate fastening devices.
  • the rail is fastened by the rail fastening device to be fixed on the base plate.
  • the rail fastening device is fixed in the rail fastening device fixing recess.
  • the base plate is fastened on the sleeper by the base plate fastening device.
  • the base plate fastening devices are placed at different positions in the longitudinal direction of the sleepers but at the same positions in the lateral (width) direction thereof such that centres of the devices match corresponding centres of the sleepers, angles at which the base plates are to be fastened are not limited, irrespective of the type of turnout. Therefore, any kind of PC sleepers can be used for all kinds of turnouts. That is, the PC sleepers can be used with the turnout. In addition, since the base plates having the same configuration are used, this is very cost-effective. Further, the present invention is not limited to PC sleepers but is applicable to steel sleepers, resinous sleepers, or slab plates.
  • an electric insulator is interposed between the base plate fastening device and the base plate such that the electric insulator abuts against the base plate fastening device and the base plate, the electric insulator having projections provided at portions with which the base plate fastening device is in contact for preventing the base plate fastening device from being released, a surface of the electric insulator being formed such that it abuts against the curved surface of the base plate and is a curved surface corresponding to the curved surface of the base plate , and a further surface of the electric insulator being formed such that it abuts against the curved surface of the base plate fastening device and is a curved surface corresponding to the curved surface of the base plate fastening device.
  • the projections provided at the electric insulator prevent the base plate fastening device from being released, which reliably avoids the release of the device.
  • a turnout base plate fastening structure in which the base plate is fixed on a sleeper by a base plate fastening device and a rail is fastened to the base plate by a rail fastening device, and the base plate has a rail fastening device fixing recess, characterized in that an electric insulator is interposed between the base plate fastening device and the base plate such that the electric insulator abuts against the base plate fastening device and the base plate, side end portions of the base plate are capped with members protruding from both ends of the electric insulator, a surface of the electric insulator is formed such that it abuts against the base plate fastening device and is a curved surface formed by a circular arc of a circle made with a centre of the base plate as a centre of the circle, and a surface of the base plate fastening device is formed such that it abuts against the curved surface of the electric insulator and is a curved
  • the side end portions of the base plate are capped with the members protruding from both ends of the electric insulator.
  • the electric insulators are integral with the base plate and the circular-arc surfaces of the electric insulators abutting against the base plate fastening devices are rotated at a predetermined angle along the circular-arc surfaces of the base plate fastening devices, to thereby position the base plate on the sleeper.
  • the base plate further has a rail fixing recess.
  • the rail is fixed in the rail fixing recess, to improve fixation of the rail.
  • PC sleepers 1 are placed in a track bed at appropriate intervals and parallel with each other (at right angles to a rail).
  • a base plate 2 placed on the sleeper 1 is a base plate 2 fixed by means of a base plate fastening device 3 with a plate 2' interposed between them.
  • the base plate fastening device 3 is adapted to press the base plate 2 downward by an elastic force of a wire spring clip 5 inserted through a hole formed in a member 4 fixed on the PC sleeper 1 by an anchor 62 or 63 shown in FIG. 12, to thereby fix the base plate 2 on the PC sleeper 1.
  • an electric insulator 6 is interposed such that it abuts against both of them. The electric insulator 6 may be dispensed with as necessary.
  • Reference numeral 7 denotes a stock rail and reference numeral 8 denotes a tongue rail.
  • a rail base 7a of the stock rail 7 is in a rail fixing recess 9 and the stock rail 7 is fixed on the base plate 2 by a rail fastening device 10.
  • the rail fastening device 10 is a brace-type elastic fastening device without using a screw or a spike, in which a clip engagement member 11 having an inversely U-shaped configuration is fixed on the base plate 2 by welding.
  • a rail brace 12 has holes penetrating through a rear portion thereof, into which the clip engagement member 11 is fitted, and a wire spring clip 13 having a substantially spiral configuration seen in a plan view is placed on the rail brace 12 such that it is elastically deformed and an end portion thereof is inserted into the clip engagement member 11, to thereby fasten the rail brace 12 and the rail 7 by an elastic force of the wire spring clip 13.
  • a protrusion 12a of the rail brace 12 is fixed in a rail brace fixing recess (rail fastening device fixing recess) 14.
  • end faces 2a and 2b of the base plate 2 in the longitudinal direction thereof are formed as being curved surfaces formed by a circular arc of a circle made with a centre 15 of the base plate 2 as a centre of the circle and a radius r (referred to as "circular-arc surfaces").
  • Inner surfaces 6a of the electric insulators 6 are formed such that they abut against the circular-arc surfaces 2a and 2b, respectively, at both ends of the base plate 2 and are circular-arc surfaces corresponding to the circular-arc surfaces 2a and 2b.
  • outer surfaces 6b of the electric insulators 6 are formed as being circular-arc surfaces.
  • Surfaces 4a of members 4 of the base plate fastening devices 3 are formed such that they abut against the outer surfaces 6b of the electric insulators 6 and are circular-arc surfaces corresponding to the outer surfaces 6b.

Still further, the projections provided at the electric insulators for preventing the base plate fastening device from being released reliably avoids the release of the device. Moreover, since the rail is fixed in the rail fixing recess, fixation of the rail is improved.
