Abstract

A machine (1) for compacting the ballast bedding of a track (2) consists of a machine frame (4) supported on rail bogies and a height-adjustable stabilization unit (9) connected to it. This can be displaced by vibrators (15) in vibrations running horizontally and perpendicular to the longitudinal direction of the machine, and can be moved on the track by means of flanged wheels (11). The spacing of the flanged rollers (11) from one another, which is perpendicular to the longitudinal direction of the machine, can be changed by means of a spreading drive (13). This is designed as a multi-position cylinder comprising a first and a second cylinder tube (22, 23) arranged one behind the other in the axial direction, each with a first and a second, double-acting piston rod (24, 25). This is connected in an articulated manner to an adjacent axis (26) of one of the flanged rollers (11) opposite one another with respect to the axial direction. <IMAGE>

Description

  • The invention relates to a machine for compacting the ballast bedding of a track with a machine frame supported on rail bogies and a height-adjustable stabilization unit connected to it, which can be displaced by vibrators in vibrations running horizontally and perpendicular to the longitudinal direction of the machine and can be moved by track rollers, the spacing of which is perpendicular to the longitudinal direction of the machine is changeable by means of an expansion drive.
  • A track stabilizer coupled to a tamping machine is known from US Pat. No. 4,046,079. This is equipped with a height-adjustable stabilization unit between its rail bogies. This can be moved on the track via flanged wheels and can be positively engaged with the track with the help of roller pivots that can be swiveled to the side. In connection with vibrators, horizontal vibrations perpendicular to the machine longitudinal direction are transmitted to the track under the influence of a static load. The mentioned flanged wheels of the stabilization unit are pressed against the inside of the rail head with the help of spreading drives while switching off the track play.
  • The object of the present invention is to create a machine of the type described in the introduction, the stabilizing unit of which can also be used in switches.
  • This object is achieved in the machine described in the introduction in that the expansion drive is formed as a multi-position cylinder from a first and a second cylinder tube arranged one behind the other in the axial direction, each with a first and a second, double-acting piston rod, each with an adjacent axis one of the flanged rollers lying opposite one another with respect to the axial direction is connected in an articulated manner.
  • With such a design of the spreading drive, there is the advantageous possibility of changing the track width of the flanged rollers in relation to the operating conditions by means of different positions of the piston rods to change quickly and easily. There are now three different track gauges to choose from, the middle one of which enables the stabilization unit to be used freely in switches, avoiding the risk of derailment or wrong-way driving. With the smallest track width, placing the stabilization unit on the track for work is considerably simplified. The third position, which is not fixed in the track gauge, is intended for normal work in the track area.
  • Further advantageous refinements of the machine according to the invention result from the subclaims.
  • The invention is described in more detail below with reference to an embodiment shown in the drawing.
  • Show it:
    • 1 is a side view of a machine for compacting the ballast bedding of a track with stabilizing units that can be set into horizontal vibrations,
    • 2 shows an enlarged cross section through the machine according to section line II in FIG. 1 with a view of a stabilizing unit having an expansion drive,
    • 3, 4 and 5 each show a schematic representation of the expansion drive in different piston positions, and
    • Fig. 6 is a schematic representation of a switch.
  • The machine 1 shown in FIG. 1 and generally also referred to as a track stabilizer for compacting the ballast bed of a track 2 consists of a machine frame 4 supported on rail bogies 3, to which an energy unit 5 with a travel drive 6 and driving cabins 7 are assigned. Between the two rail carriages 3 arranged at the ends and below the machine frame 4, two stabilizing units 9 which are height-adjustable by drives 8 are provided. A reference system 10 serves to control the lowering of the track.
  • As can be seen in FIG. 2, the stabilization unit 9 rests on rails 12 of the track 2 by means of (four in total) flanged wheels 11. In each case two flanged rollers 11 lying opposite one another in the cross-machine direction are connected to a hydraulic spreading drive 13. Two vibrators 15 designed as eccentric drives are mounted in a unit housing 14 connected to the drives 8. These are designed to generate vibrations running in the cross-machine direction and parallel to the axes of rotation 16 of the flanged rollers 11. Between the two wheel flange rollers 11, each assigned to a rail 12, so-called roller tongs 17 are mounted on the unit housing 14 so as to be pivotable about an axis 18 running in the machine longitudinal direction. This pivoting takes place by means of a hydraulic drive 19. At the lower end of each roller tongs 17, a roller table 21 rotatable about an axis 20 is provided.
  • Each expansion drive 13 is composed of two cylinder tubes 22, 23 arranged one behind the other in the axial direction, each with a first and a second piston rod 24, 25, forming a common structural unit or a so-called multi-position cylinder. Each of the two piston rods 24, 25 is connected in an articulated manner to an adjacent axis 26 and fastened to a flange roller 11. While the axis 26 shown in FIG. 2 on the right half of the image is mounted in a bearing 27 in the direction of the axis of rotation 16, the axis 26 visible on the left half of the image is rigidly connected to the bearing 27.
  • As can be seen from FIGS. 3 to 5, the stroke length of the two piston rods 24, 25 is of different lengths. The stroke length of the first piston rod 24 is 15 mm and that of the second piston rod 45 mm. 3, the piston rods 24, 25 are retracted, so that the smallest possible track width of 1420 mm results for the flange rollers 11. This track width is provided for placing the stabilization unit 9 on the rails 12 (single iron).
  • 4, the second piston rod 25 having a longer piston stroke is retracted, while the opposite first piston rod 24 is extended. This results in a standard track width of 1435 mm. As will be described in more detail in relation to FIG. 6, this position is suitable for use in switch sections.
  • 5, both piston rods 24, 25 are extended, the track dimension resulting from the existing track gauge and the elasticity of the rail fastening. This means that the flanged wheels 11 regardless of possible track width errors u. The like. Are constantly pressed against the inside head flanks of the rails 12.
  • Before reaching a switch 28 shown in FIG. 6, both roller tongs 17 of each stabilization unit 9 are pivoted downwards, ie. H. engaged with the rails 12. Assuming that the machine 1 is moved in the direction shown by the arrow 29, the right roller tongs 17 of both stabilizing units 9 are swiveled up immediately before a switch tongue 30 or an outer strand 31 of a branch track 32 is reached. At the same time, the spreading drives 13 acted on such that the piston rods 25 are retracted with the longer stroke (see position Fig. 4). This results in a transmission of the horizontal vibrations via the still present positive connection between the stabilizing unit 9 and the left rail 12, while the right flanged rollers 11 are spaced apart from the inner edge of the right rail 12 in the normal way of tracking. Immediately after the switch tongue 30, the right roller tongs 17 can in turn be brought into engagement with the right rail 12, at the same time the left piston rods 25, which have a longer piston stroke, are also extended (see position FIG. 5). Immediately before reaching the centerpiece 33, the process just described is repeated for working through the points by pivoting the right roller tongs 17 up and retracting the piston rods 25 of the expansion drives 13.
