Machine for uninterrupted insertion of electric overhead contact wire - Maskin för att kontinuerlig förlägga en kon-tactträd av en elektrisk luftledning 5

The invention relates to a machine for positioning an overhead wire and / or carrier cable for a rail, and maintaining a certain tension at the inserted overhead line, which includes a runner-supported machine-10 frame, a rotatable axis longitudinally adjustable, a crane boom having a rotatable pivoting roller and a tensile tensioner located in the drive direction between the wire drum and the pivoting roller, having a brake actuator 15 which provides a tensile pull when the machine is in a continuous forward motion.

EP 0 416 136 B1 already discloses one such type of machine 20, whereby the overhead line cable and the guide wire of the railway track are laid together without interruption and kept under tension for the duration of the installation. The driving wire and the carrying cable are then wound from the respective wire drum placed on the machine frame and, after passing through the tensioning device, are brought to the correct height and lateral position by means of their respective adjustable pivoting rollers. Both traction tensioners are always equipped with a braking system which adjusts the traction tension of the inserted overhead line according to the number of tracks, so that the machine runs continuously along the track. Each wire drum is mounted on its own support frame 4, movable and movable in the longitudinal direction of the drum shaft - together with a corresponding tensile tensioning device, whereby this drum shaft extends substantially horizontally and transversely of the machine 35.

Another machine for positioning a rail overhead line is described in US 4,213,596. The contact wire is stored in a wire drum that can be affected by the braking force and is mounted, with the shaft running in the transverse direction of the machine or horizontally, on the machine frame movable on the rail. The following machine frame has height- and laterally-adjustable controls to position the wire at the desired position during installation.

It is an object of the present invention to provide a kind of machine which can also easily dismantle drums in which the driving wire is wound onto the drum in a plane approximately symmetrical to the drum axis.

This object is achieved by the machine described initially, with the wire drum and its drum axis adapted to run vertically and the tensioning device and / or the wire drum being arranged to be moved by the drive device in the longitudinal direction of the machine.

With this structure, the positioning of the wire drum is already prepared for disassembly at the installation site in relation to its plane of symmetry. In connection with the movable position of the draw-25 tensioner and the tach or wire drum, a straight-line unlocking of the contact wire is ensured, avoiding bending, independent of the opening speed.

The invention will now be explained in more detail with reference to the drawings, in which Fig. 1 is a side elevational view of a machine for uninterrupted insertion of an overhead line of wire and a wire drum for dismantling the wire, Fig. 2 is a top plan view of the machine; wire drum arrow III of Figure 2, the.

The machine 1 shown in Figures 1 and 2, which is uninterrupted i for insertion of the overhead contact wire 2 and / or the carrier cable 3, has a machine frame 6 supported on the rails 5 on the rail 5. 7 or a work cabin 8 with control arrangements 9. A rotatable swivel crane 13 adjacent to the work cabin 8 is provided with a height-adjustable work platform 14 which is horizontally pivotable. The two drive-10 actuators 10 mounted on the machine frame 6, running rails 4, drive the actuators 11 and the hydraulic pump 12 for powering the other actuators of the machine 1 still to be described.

The wire drum 15 on which the driving wire 2 or the carrier 15 rope 3 to be placed is rolled is rotatable about the drum shaft 16 and can be axially displaced on the machine frame 6, as can be more clearly seen with reference to FIG. Separated from the wire drum 15 in the longitudinal direction of the machine or mounted 20 in the traction direction of the contact wire 2 (see arrow 44), a tensioning device 26 is disposed, followed by a rotatable pivoting roller 17. It is located by the actuator 19 at a freely adjustable is connected to it by a hinge 20 which acts in all directions.

As specifically shown in detail in FIG. 3, the thread drum 15 is secured to the drum clamp 22 by means of bearing supports 21 disposed within the support frame 23 and pivotable about a pivot axis 24 extending horizontally in the machine transverse 30 direction. The actuator 25 allows a common rotation of the drum holder 22 and the wire drum 15 from a workstation where the drum shaft 16 extends vertically to another position where the drum shaft 16 is arranged horizontally. This station 35, shown by dotted dashes, is provided for replacing the wire drum 15. For this purpose, the second bearing bracket 21, together with the rotating device 27 of the wear drum tree 15, is disposed on a sliding rail 108342 and is designed to be displaced longitudinally by the drum shaft 16 by the drive 29 and relative to the drum holder 22. Thus, t the two bearing brackets 21 can be spaced apart for insertion or removal of the wire drum 15. The rotation device 27 is provided with a torque support 30.

The support frame 23, together with the spool drum 15 and the drum holder 22, is now positioned to be moved vertically along the guides 31 in the machine core 10. To effect this height adjustment perpendicular to the longitudinal direction of the machine, there are actuators 32 that are pivotally mounted on a support 33 and a support body 23 connected to the machine frame 6. The drive wire 2 (not shown in Figure 3) is roll-15 loaded onto the wire drum 15 so that is already in the correct position corresponding to the set end position with respect to the vertical plane of symmetry. The vertical positioning or retrofitting of the wire drum 15 ensures that when pulling the drive wire 2 out of the drum, it is always guided horizontally to the tensioning device 26 (see Figure 1), thereby avoiding as much as possible twisting of the wire.

The tensioning device 26 essentially comprises two groove-type pivoting rollers 34 having relatively large diameters disposed in succession in the longitudinal direction of the machine and interconnected by a transmission chain 35, whereby the second pivoting roller 34 may be actuated by the brake-30 apparatus 36. under tension by means of a tensioner 37. Both swivel castors. : 34 are mounted on the pivot body 38, which is built on horizontal guides 39 perpendicular to the machine longitudinally, and movable by means of actuators 40 in the transverse direction of the machine and further parallel to the axis 41 directed in the longitudinal direction of the machine; 108342 5 with respect to the conductors 39. The pivoting roller 34 coupled to the braking device 36 is further provided with a brake disc 42 which acts in conjunction with the emergency brake 43 which, in the event of a failure of the braking device 36, prevents the uncontrolled pull-out of the contact wire 2. The transverse displacement of the pivot body 38 ensures that the drive wire 2 pulled from the yarn drum 15 is guided exactly in line with the grooves in the pivot rolls 34, thereby preventing the wire from slipping off the roll.

Alternatively, it would also be possible for the spool drum 15 to be disposed unmoved on the machine frame 6, whereby the tensioning device 26, which is parallel to the transverse displacement, is positioned so that it can also be positioned vertically. Otherwise, however, the tension-tension 15 device 26 could be fixedly fixed to the machine frame 6, while the wire drum 15 is constructed to be movable in both height and transverse directions.

The working mode 20 of the tensioning device 26 or the braking device 36 for providing a proper tensioning tension while the machine 1 is in an uninterrupted forward movement when the track air duct is in place and the tension applied to the inserted air duct is operation of the pivotally mounted pivoting roller 17.
