Definitions

  • the invention relates to a device for ironing a tool frame onto the rails of a track, with a sensing element scanning a rail, the flanged wheels having tool frames articulated by drives on the machine frame of a track-moving track construction machine and lockable in an inoperative position (cf. DE-A-2927729 and Preamble of claim 1).
  • a device for ironing or centering a tool frame of a track construction machine which is articulated on a machine frame by height adjustment drives.
  • the tool frame is automatically centered in relation to the center of the machine in its raised, inoperative position.
  • the single track device which is also articulated on the machine frame independently of the tool frame, essentially consists of a pair of levers which act as a sensing element and which are fastened to their own frame articulated on the machine frame in such a way that the levers can be pivoted in a vertical plane running in the transverse direction of the track.
  • the pivot axes of the levers or sensing elements are spaced horizontally from one another approximately in the track gauge of the track.
  • the levers are also coupled to one another via a synchronization rod in such a way that the movement of one lever by means of a swivel drive causes a movement of the other lever which is a mirror image thereof.
  • the free lower ends of the levers are designed as button stops for contact with the inside of the rail head.
  • the sensing elements are pivoted too high towards the center of the machine.
  • the swivel drive is acted upon and there is a synchronous spreading movement of the feelers towards the inside of the rail heads. Is If the single track device is not exactly centered over the middle of the track - for example because the machine is on a track curve - then it is inevitable that one of the probes first touches the assigned rail head.
  • the frame of the single track device is shifted in the direction of the center of the track until the other sensing element also bears against the rail head assigned to it and the device is thus centered precisely in relation to the center of the track.
  • the frame of the single track device then serves to steer the tool frame into the correct track-centered position while it is being lowered onto the track.
  • finger-like directional supports are attached to the tool frame, which are deflected by guide ramps arranged on the frame of the single track device until the flanged wheels of the tool frame engage the rails and the tool frame is thus slid in.
  • the structure of this single track device is relatively complicated and, when used in track ramp areas with uneven track heights, it can tend to malfunction.
  • the object of the invention is therefore to provide a single track device of the generic type, by means of which a trouble-free and reliable single track of the tool frame is ensured.
  • the feeler connected to the tool frame is arranged at least during the single track operation in the radial plane of at least one flanged wheel and is connected to a hydraulic control for interrupting the application of a transverse displacement drive articulated between the machine and tool frame and / or to deliver a acoustic or optical signal is trained.
  • a single-track device which is particularly simple in design, has the great advantage that the single-track operation can be carried out in a simple manner only with the aid of a transverse displacement drive due to the connection of the tool frame and feeler element.
  • the tool frame is thus moved until the correct position of the flanged wheels above the rails is finally displayed by a reaction of the sensing element and the operator stops the transverse movement or this is automatically interrupted by the sensing element. Subsequently, the tool frame only needs to be lowered onto the track. Since in most cases the cross-slide drive is already present for the work of the tool frame, only the arrangement of a feeler is required for the simplest embodiment of the single-track device according to the invention.
  • the development of the invention according to claim 2 has the advantage that an automatic alignment of the flanged wheel axis parallel to the track plane can be achieved already after the first part of the single track process by lowering the tool frame due to the slide bar resting on the track, in particular also in track sections with a transverse inclination.
  • As a second part of the single track process only an action on the transverse adjustment drive and thus a displacement of the slide rail in the transverse direction of the track is required, the exact position of the rails being able to be determined quickly and easily with the response of the sensing element.
  • the aforementioned first stage of the single track process as a result of the slide bar resting on both rails has the particular advantage that, prior to the final lowering of the flanged wheels, they are always spaced at the same height from the rail.
  • the configuration according to claim 3 ensures that the sensing element forming part of the slide bar responds reliably in the region of a rail head, so that a precise centering of the flanged wheels above the rail head can be achieved for trouble-free insertion of the tool frame.
  • the arrangement cited in claim 5 advantageously ensures a limitation of the transverse sliding movement of the slide bar, the tool frame being fixed precisely and immovably in the desired position by latching the rail head on the vertical stop - in cooperation with the blocking of the transverse sliding drives triggered by the sensing element.
  • the design of the device according to claim 9 has the advantage that the slide bar is firmly connected to the tool frame while avoiding a structurally somewhat more complex pivotable linkage, the flanged wheels being located above the bearing surface during the scanning process of the slide bar.
  • a mobile track construction machine 1 shown in FIG. 1 has a bridge-shaped machine frame 4 which is mounted on a track 3 at the end via rail carriages 2.
  • Two height and side adjustable tamping units 5, a lifting and straightening unit 6 having lifting and straightening drives and a leveling and straightening reference system 7 controlling these units are arranged on this for carrying out the track construction work.
  • An energy center 8 serves to supply all the drives arranged on the track-laying machine 1.
  • a measuring trolley 9 that can be rolled off the track is provided, which is connected to the machine frame 4 between the rail carriages 2, which are spaced far apart from one another, by means of drives that can be adjusted in height and crosswise, and is equipped with a single track device 10 for centering during the single track process.
  • a central control device 46 is arranged in a work cabin.
  • the single track device 10 shown in FIGS. 2 and 3 consists of two - in their lower scanning position - each above a rail and parts arranged in mirror image to one another, of which for the sake of simplicity only the part located above the left rail is shown.
  • This part of the single track device 10 has a support frame 11 which is fixedly connected to a tool frame 12 of the measuring carriage 9.
  • the tool frame 12 is in turn articulated or adjustable to the machine frame 4 of the track-laying machine 1 by means of height adjustment drives 13 and transverse adjustment drives 14 and is further provided with flange wheels 15 which are provided for resting on rails 16 of the track 3.
  • a swivel frame 17 extending transversely to the longitudinal direction of the machine is articulated on the support frame 11 via a parallelogram linkage formed by two levers 18 and is adjustable to this by means of a swivel drive 19 likewise arranged on the support frame 11 and designed as a spring-loaded cylinder, in a swivel plane which extends perpendicular to the track plane and in the cross-machine direction (see the swiveled-up position indicated by dash-dotted lines on the left side of FIG. 2). In its lower end position or scanning position for carrying out the single-track operation, the swivel frame 17 bears firmly against a vertical stop 20 of the support frame 11 to limit its swivel movement.
  • the lower end region of the swivel frame 17, which runs essentially parallel to the track plane or to the axis 50 of the flanged wheel 15, is designed as a slide bar 21 which consists of two bar sections 22 which are offset in height from one another, the lower bar section 22 having a vertical stop 23 for contact with the Has side surface of a rail head 24 of the rail 16.
  • the length of the strip sections 22 results from the arrow height of the circular arc described by the track with a minimal arc radius as a function of the length of the circular chord formed by the spaced-apart rail carriages 2.
  • the slide bar 21 For resting on the rail head 24 is the slide bar 21 with a bearing surface 25 provided from electrical insulation material 26.
  • a sensing element 27 is arranged in the middle with respect to the two strip sections 22 extending transversely to the machine longitudinal direction, which is designed as a rocker arm 28 likewise coated with electrical insulation material 26, which actuates a limit switch 29 in its upper end position.
  • the latter is connected via a line 30 to a hydraulic control 51 for controlling the application of the transverse adjustment drive 14.
  • the hydraulic control 51 is composed of a 4/3-way valve 52 with a zero circulation position and two flow positions and a 4/2-way valve 53 with a zero rotation position and a flow position.
  • the limit switch 29 is also connected to an optical and / or acoustic signal device 54.
  • the measuring carriage 9 Before the single track process, the measuring carriage 9 is in its inoperative position which is raised or raised from the track 3.
  • the swivel frame 17 When the respective swivel drives 19 are acted upon, the swivel frame 17 is first pivoted into its lower end or scanning position until it abuts the stop 20. In this position, the feeler element 27 arranged on the slide bar 21 is located below the flanged wheel 15 in its radial plane 55 running perpendicular to the axis 50.
  • the tool frame 12 is then lowered by means of the height adjustment drives 13 until the slide bar 21 rests on the rail head 24.
  • the transverse adjustment drives 14 When the transverse adjustment drives 14 are now acted upon, the tool frame 12 and thus the associated single-track device 10 or the slide bar 21 in the transverse direction of the machine are moved or scanned.
  • the flanged wheel 15 is in the desired position above the rail 16 or the radial plane 55 mentioned is approximately identical to the rail symmetry plane.
  • the rocker arm 28 is operated simultaneously and pressed with its free end against the limit switch 29.
  • the pulse triggered in this way causes an electromagnetic displacement of the valve 53 into the zero position, as a result of which the transverse adjustment drive 14 is blocked and the scanning movement is ended.
  • the operator is shown the correct position of the flanged wheels 15 above the rails by an optical and / or acoustic signal.
  • the height adjustment drives 13 can be used to finally lower the tool frame 12 or measuring carriage 9 into the working position until the flanged wheels 15 rest on the rails 16.
  • the valve 53 is displaced into the flow position under the action of a return spring, so that the transverse adjustment drive 14 can be used unhindered for the lateral spreading of the measuring carriage 9 on one of the two rails in the course of the work of the machine 1.
  • a track construction machine 31 has a machine frame 32, to which - via height adjustment drives 33 and a transverse adjustment drive 34 - a tool frame 35 is articulated in a height-adjustable and transverse manner.
  • This is equipped with working tools (not shown here in more detail), for example lifting rollers for lifting and straightening the track, and is connected to a slide bar 36 which extends in the form of a bar 37 over both rails 38 of a track 39.
  • sensing elements 40 are arranged at a distance from one another in the track width.
  • the two end sections 41 of the bar 37 are (as indicated by the left arrow) with respect to the middle part of the height lying between the sensing elements 40 arranged offset and thereby form step-shaped stops 42, which are provided for contact with a rail head 43.
  • the length of these end sections 41 corresponds to the largest required lateral deflection of the tool frame 35 from the center of the machine in track arches (depending on the distance between the trolleys of the track-building machine 31).
  • the tool frame 35 is equipped with flange wheels 44, which are each mounted on the tool frame 35 so as to be vertically displaceable in corresponding vertical guides by means of their own adjustment drive 45. In its upper end position, the flanged wheels 44 are located above the feeler elements 40 arranged on the slide bar 36 and also above the bearing surface of the slide bar 36.
  • the single track or centering process begins with the lowering of the tool frame 35 using the height adjustment drives 33 until the slide bar 36 rests on both rail heads 43 (see the position shown in FIG. 4).
  • the transverse adjustment drive 34 there is then a displacement of the tool frame 35 in the transverse direction of the machine, which is terminated when the rail heads 43 engage on the stops 42 and / or the associated actuation of the pushbuttons 40 by a switch-off signal emanating from them to the transverse adjustment drive 34.
  • the flanged wheels 44 are now centered exactly above the rails 38 and are lowered by acting on the adjustment drives 45 until they engage the rail heads 43.
  • a sensing element 56 shown in FIG. 5 is attached as an inductive proximity switch for contactless scanning of the rail 16 on the support frame 11 in the center with respect to the radial plane 55 of the flange wheel 15.
  • the single track process is initiated by swiveling the swivel frame 17 down into the scanning position. After lowering the single track device 10 together with the associated tool frame and support of the slide bar 21 on both rails 16 of the track, there is a transverse displacement of the entire unit until the pushbutton 56 in its position exactly above the rail 16 blocks the transverse adjustment drive and / or triggers an acoustic or optical signal.
