Definitions

• the invention relates to a machine according to the features cited in claim 1 or 2 in the preamble and a method.
• US 4 249 467 discloses a machine for transporting track switches and their storage on a ballast bed. At each end of a switch carrier bearing the switch carrier two rail bogies and a crawler track are connected to the switch carrier.
• the object of the present invention is now to provide a machine of the generic type, with the consideration of different site conditions more versatile work assignments are possible.
• FIG. 1 and 2 are each a half of a machine for transporting and laying a track switch in side view
• Fig. 3 and 4 each have a cross section along the section line III and IV in Fig. 1 and 2
• Fig. 5 a Top view of a part of the machine
• Fig. 6 shows a further embodiment.
• a machine 1 shown in FIGS. 1 and 2 has an elongated, beam-shaped switch carrier 3 for transporting a track switch 2. This is made up of a middle support section 4 supporting the track switch 2 and two end support sections 6 each connected thereto by a support joint 5. These are each mounted on a chassis support 9 connected to two track gears 7 and a crawler chassis 8 positioned centrally therebetween.
• the crawler undercarriage 8 is rotatable about a chassis axle 11 by a rotary drive 10 and equipped with a traction drive 13 which can be supplied by an engine 12.
• Each rail chassis 7 is vertically adjustable by a drive 14 along a pivot axis 15 relative to the chassis carrier 9. Between rail and crawler undercarriage 7, 8 each a height-adjustable Hubstempel 36 is attached to Fahrtechnikstr ger 9.
• cable winches 16 are arranged in a carrier longitudinal direction or longitudinal axis 20 one behind the other on the central carrier section 4, these being connected in pairs via a cable 19 to a fastening device 17 in the form of a transverse yoke 18.
• Each transverse yoke 18 has (see Fig. 4) in the middle of an opening 21 for receiving a center carrier portion 4 connected to the center and extending therefrom centering pin 22.
• Fixing hooks 23 connected to the transverse yoke 18 are with a hook 25 in a direction normal to the beam longitudinal direction 20 transverse direction under a rail 24 of the track switch 2 slidably.
• the end-side support section 6 is mounted so as to be pivotable about a pivot axis 26 extending in its longitudinal direction on a pivot support 27 connected to the chassis strut 9.
• a pivot drive 28 with the support portion 6 and the pivot support 27 is provided for pivoting a pivot drive 28 with the support portion 6 and the pivot support 27 is provided.
• the pivot axis 26 is positioned centrally with respect to a chassis axis 29 of the crawler chassis 8.
• a pivoting angle ⁇ (see Fig. 4) is limited on the one hand by the - indicated in dash-dotted lines - transport position and on the other hand by the laying position of the end-side support portion 6.
• the carrier joint 5 has (in the laying position) a carrier axis 30 parallel to the chassis axis 11 (FIG. 1, 2). The distance between the carrier axis 30 and chassis axle 11 is greater than the distance to the pivot axis 15th
• the carrier joint 5 can be distanced by a telescopic drive 31 mounted in the end-side carrier section 6 relative to the chassis axle 11 in the carrier longitudinal direction 20.
• the end-side support section 6 is extended in the direction from the support axis 30 to the chassis axle 11 beyond this by a counterweight section 32. This can be distanced from the pivot axis 26 by a drive 33 for improved action as a counterweight.
• the machine 1 is moved at raised rail bogies 7 with the help of 90 ° twisted crawler tracks 8 in the transverse direction until the switch carrier 3 comes to rest on the track 2.
• the rotary drives 10 - and the associated pivoting of the end-side support sections 6 - are parallel to this position at any time ments of the central support section 4 to the exact centering over the track switch 2 possible.
• the fastening devices 17 and transverse yokes 18 are lowered, the hooks 25 are pushed and anchored under the rails 24.
• the track switch 2 is raised by means of the winches 16 until the centering pins 22 automatically dive into the openings 21 of each transverse yoke 18 and these are pressed against a lower side of the central support section 4.
• the track switch 2 Under the action of the winches 16, the track switch 2 is placed on a ballast bed 35, wherein at any time by the rotary actuators 10 a precise position adjustment is feasible. Once the track switch 2 rests on the ballast bed 35, there is a release of the hook 25, the transverse displacement of the transverse yoke 18 and its lifting for the introduction of the centering pin 22nd
• the machine 1 can be discontinued by lifting the rail chassis 7 on the two pivoted by 90 ° crawler tracks 8 and moved by the drives 13 in the transverse direction until the Unloading position is reached.
• the correct positioning of the track switch 2 can be substantially facilitated, in particular in cramped tunnel conditions, with a corresponding action on the rotary drives 10. '5.
• the lifting ram 36 are pressed against the end-side support portion 6 (Fig. 2). This allows the - in the direction of travel - rail chassis 7 without the use of ramps easily be placed on the track 34.
• activation of the drive 14 is a lowering of the rail chassis 7 and an associated increase in the crawler chassis. 8
• both unimpeded pick-up transport on a regular track and problem-free storage of the track switch 2 in its installed position is possible in a particularly advantageous manner, wherein - for the change from transport to installation function - no costly retooling and no additional auxiliary equipment required are.
• winches 16 is achieved by the centering pins 22 a very simple, rapid and effective connection between the switch carrier 3 and 2 track for their safe transport in an inclined position.
• the track switch 2 can be lowered immediately, completely avoiding dangerous and difficult conversion work due to the heavy load.
• precise position corrections for a precise turnout installation are possible at any time during the Abse nk- movement.
• a problem-free transverse transport from track 34 to the installation point is ensured while avoiding swinging movements that stress the switch and are dangerous due to the heavy load.
• an extension of the end-side carrier section 6 can optionally be carried out with the aid of the drive 31.
• the counterweight portion 32 could be spaced by the drive 33 to increase the counterweight of the chassis axle 11.
• the support joint 5 can also be designed as a universal joint for an all-round mobility of the interconnected support sections 4, 6.
