Definitions

  • the invention relates to a device for grinding rails of a track, with an aggregate frame that can be supported by support rollers with axes of rotation on both rails, to which a grinding aggregate is assigned with a grinding member that is adjustable in the area of a rail and attached to a supporting frame, the supporting frame together with the grinding member by a Swivel drive is mounted on the unit frame so as to be pivotable about a swivel axis, and with a drive motor fastened to the unit frame at a distance from the support frame.
  • Devices of this type are used for grinding in accordance with the profile, in particular of the running surfaces and running edges of railroad tracks, in order to eliminate unevenness on the rail head which occurs as a result of wear or after welding work.
  • a device for grinding rails of a track which has a unit frame that can be moved on support rollers. This is connected in the area of one of the rails to a support frame, on which a grinding wheel is arranged as a grinding element and is adjustable in angle to the longitudinal direction of the rail by means of a lever device serving as a pivot drive.
  • the motor or the drive unit for the grinding element is located on the side of the unit frame facing away from it and is connected to the grinding element by means of a flexible shaft. With this device, only the running surfaces of the rails can be ground.
  • EP 0 110 246 B1 describes a device with a unit frame that can be moved on the rails via support rollers, on which a support frame is arranged in the area of one of the rails, and is designed to be tiltable about a pivot axis aligned in the longitudinal direction of the track by means of a spindle drive articulated on the unit frame in the manner of a cantilever .
  • a belt sanding unit with its motor attached to the support frame is equipped with a height-adjustable pressure roller and can also be pivoted about a vertical axis to the support frame.
  • the object of the present invention is to create a generic device for grinding rails, with which both the tread and the inner edges of the rails can be processed with a minimum of operational effort.
  • This object is achieved with a device of the type mentioned above in that the distance between the support frame or the pivoting axis running in the longitudinal direction of the track and a support roller opposite the grinding unit in the transverse direction of the track is designed to be reducible by a length compensation unit, this length compensation unit being a pressure element for generating an against the Distance reduction effective contact pressure of the grinding unit to an inner rail head flank of the rail to be ground.
  • Such a device now makes it possible, for the first time, to apply the contact pressure of the grinding member, which is required for grinding the inner flanks of a rail, largely automatically or automatically, neither the muscle strength of an operator nor any complex control mechanisms being required.
  • a transverse pivoting of the grinding member also simultaneously shortens the unit frame in the transverse direction of the track, which optimally involves tightening the pressure member to generate the contact pressure. In addition to an increase in the quality of work, this also considerably simplifies the operating effort and relieves the workforce.
  • the arrangement according to claim 2 ensures the greatest possible transverse adjustment of the support frame or reduction in distance of the grinding member to the opposite rail. This leads to a gradual build-up of the required contact pressure as part of the displacement of the swivel axis in the direction of the inside of the rail head.
  • the support rollers are advantageously used at the same time as - guiding the grinding element at the correct distance on the rail head - rollers, this distance also being maintained during the pivoting of the support frame about the pivot axis running in the longitudinal direction of the track . This also helps to prevent copying or reinforcement of short-wave rail unevenness with the grinding element.
  • the device 1 shown in FIGS. 1 to 4 for grinding rails 2, 3 of a track 4 has an aggregate frame 5 extending in the transverse direction of the track and a support frame 6 running in the longitudinal direction of the track, which in the area of the one rail 3 to be ground with the Unit frame is connected.
  • the unit frame 5 consists of two Frame parts 7,8 together, which are each assigned to a rail 2 or 3.
  • the frame part 7 opposite the support frame 6 and distanced from it consists of two angle brackets 9 aligned parallel to the rail 2 and two support rollers 10 which are fastened at the ends between them and designed as double track roller wheels with axes of rotation 11 and which can be rolled on the rail 2.
  • the frame part 8 has two cross members 12 which are spaced apart from one another in the longitudinal direction of the track and which are stably connected at one end by means of a vertical plate 13 arranged between the rails 2, 3.
  • the two frame parts 7, 8 are connected to one another via a length compensation unit 14, which allows the two frame parts 7, 8 to be adjusted relative to one another in the transverse direction of the track.
  • the length compensation unit 14 is formed from two supports 15 which run in the transverse direction of the track and are fastened to the plate 13 and are each mounted telescopically displaceably in a guide tube 16 connected to the angle supports 9.
  • a pressure element 17 in the form of a helical spring 18 arranged on each support 15 between the guide tube 16 and plate 13 spreads the two frame parts 7, 8 against one another in the transverse direction of the track, a stop 48 (FIG. 3) located inside the guide tubes 16 limiting and separating this movement apart Separation of the frame parts 7.8 prevented.
  • the support frame 6 essentially consists of a longitudinal beam 20, which has a cranked section 19 distant from the rail 3 and has a cranked section 19 in its longitudinal center, which rotates in the bearing area 22 in the region of its two ends in each case about a pivot axis 21 running in the longitudinal direction of the track and parallel to the track plane is stored.
  • These bearing blocks 22 are in turn fastened at each end to the cross beams 12 of the assembly frame 5 or frame part 8.
  • Support rollers 23 are mounted on the outermost ends of the longitudinal member 20 of the support frame 6 projecting over the cross member 12, which are designed as trackless rollers 25 with their axes of rotation 24 perpendicular to the pivot axis 21 and for supporting the support frame 6 and assembly frame 5 on the Serve rail 3.
  • a grinding unit 26 Arranged within the cranked section 19 of the support frame 6 is a grinding unit 26, which is equipped with a grinding member 31 in the form of a rotating cup wheel 61 and is connected by means of a parallelogram linkage 27 to a holder 29 formed from support plates 28, which is fastened to the support frame 6.
  • an adjustment drive 30, which is mounted in the holder 29 and is connected to the parallelogram linkage 27, the grinding unit 26 or the grinding member 31 can be adjusted in its distance from the rail 3 in order to regulate the removal depth.
  • the grinding unit 26 which has a hydraulic motor, is positioned such that a point of contact 47 of the grinding member 31 with the rail 3 lies on a connecting line 49, which is determined by two roller contact points 60, each formed by a contact of the rollers 25 with the rail 3 to be machined is, the axis of rotation 62 of the cup wheel 61 perpendicular to the connecting line 49 or a longitudinal axis of the rail 3 (Fig. 3).
  • two hydraulic swivel drives 32 are provided, which are each articulated on the cross members 12 of the assembly frame 5 and on the side member 20.
  • a drive motor 33 with a hydraulic pump 34 which supplies power to the swivel drives 32 and the grinding unit 26, is arranged at a distance from the support frame 6 on a console 35 connected to the plate 13 of the assembly frame 5, while operating elements 36 for said swivel drives 32 and a feed regulator 37 for the remote control of the adjustment drive 30 on a bracket 38 of the assembly frame 5.
  • Power is supplied by hydraulic hoses 63.
  • actuation of the swivel drives 32 causes the grinding member 31 to roll in the transverse direction of the track around the head 39 of the rail 3 (see dash-dotted outline lines), the - During the entire pivoting movement on the connecting line 49 mentioned - rollers 25 always keep the grinding member 31 at the same distance from the rail head 39.
  • a supporting wheel-like guide roller 40 is fastened to the support frame 6 next to each roller 25, which can be rotated about an axis 41 which is inclined approximately 45 ° at an angle to the axis of rotation 24 of the roller 25 and runs perpendicular to the pivot axis 21.
  • the guide roller 40 is equipped with a flange 42 provided for contact with the rail head 39 or an outer rail head edge 43.
  • the pivot axis 21 of the support frame 6 is arranged in such a way that, when the frame parts 7, 8 are at a maximum distance from one another - as shown in FIGS. 1 to 3 - they are positioned on the outside of the rail 3 and both vertically and horizontally from the upper, outer rail head edge 44 is distanced. In this position, the horizontal running surface 45 of the rail is processed.
  • the swiveling axis 21 is inevitably displaced in the direction of the opposite support rollers 10 and thus the compression element 17 of the length compensation unit 14 is compressed Distance reduction between the pivot axis and support rollers counteracts and in this way generates a contact pressure with which the grinding member 31 is pressed laterally against the rail head 39.
  • the device 50 shown in FIG. 5 for rail grinding has an aggregate frame 5 formed from only one part, to which a support frame 6 is rotatably connected in the region of the rail 3 about a pivot axis 21 running in the longitudinal direction of the track.
  • the unit frame is mounted on the rail 2 via a double-track rim support roller 10 and on the rail 3 via two further support rollers 23 fastened to the unit frame 5 and designed as castors 25 and can be moved in the longitudinal direction of the track, the rollers 25 each having one - for contacting the Rail head inner flank 46 of the rail 3 provided - flange 51 are equipped.
  • the opposite end of the support frame 6 of the unit frame 5 is as formed in the cross-track direction carrier 15 on which the support roller 10 is mounted coaxially and at the same time is displaceable in the longitudinal direction of the carrier.
  • the length compensation unit 14 formed in this way has a helical spring 18 serving as a pressure element 17, the contact pressure of which is directed such that all three support rollers are pressed onto the rails 2, 3 to switch off the track play.
  • the support frame 6, which is formed with a cranked section 19, is connected via a parallelogram linkage 27 to a grinding unit 26, the grinding member 31 of which is adjustable perpendicular to the rail head 39.
  • a pivot drive 32 which is articulated both on the support frame 6 and on the assembly frame 5, is used to pivot the support frame 6 together with the grinding unit 26 about the pivot axis 21 (see the position shown in double-dashed lines).
  • the support frame 6 is also equipped with a driver element 52 which engages with the rail head 39 during the transverse pivoting of the grinding unit 26 and causes a transverse displacement of the support frame 6 and thus also of the unit frame 5 in the direction of the rail 2 or the support roller 10.
  • the helical spring 18 is compressed and exerts a contact pressure of the grinding element 31 directed against the inner rail head flank 46 of the rail 3.
  • the unit frame 5 consists of two frame parts 56, 57, which are connected to one another in a joint 54 via intermediate members 55, of which the frame part 56, which is further distanced from the supporting frame 6, is mounted on the rail 2 by means of support rollers 10 and serves to support the drive motor 33.

  • the four intermediate members 55, which form the length compensation unit 14, are pivotally connected to one another in the form of a parallelogram lying in a horizontal plane so as to be rotatable about vertically arranged axes 58 and are preloaded via a spring 59 running in the longitudinal direction of the track.
  • the spring 59 is pulled apart and then acts as a pressure element which, via the intermediate members 55 or the frame part 57, exerts a contact pressure of the grinding unit 26 against the inner rail head flank 46 of the rail 3.
  • grinding units with rotating grinding wheels or slip rings as well as belt grinding units can equally be used without any problems.
