Abstract

The machine replaces track superstructure in parts of preassembled track sections (10). By the fitting of a gantry (1) on bogies (2), of which, during work, one travels along the old track superstructure and the second along the newly laid superstructure, a space is formed under the gantry (1) for the pulling-up and laying of track sections (10) and spreading and levelling of gravel (11), by means of clamps (4) and vertically moving spreader (7). The clamps (4) and spreader (7) are fixed to a bearer (3) which is slide fitted in the gantry (1) parallel with the axis of the machine. The clamps (4) are fixed to the bearer (3) by means of a channel (5) for lateral movement of the clamps (4) in relation to the bearer (3). The spreader (7) is fixed to a bearer (3), together with an operating cabin (8), by means of a swivelling base (9). The travel of the machine along the length of the laid superstructure (10) is for brushing gravel (11) back towards the rails by means of side blades (6).<IMAGE>

Description

(57) The machine replaces the track superstructure in sections - track fields (10). By placing the portal (1) on the railway undercarriages (2), one of which travels on the old railway superstructure and the other on the new superstructure, a space is created in front of the portal (1) for pulling and laying track fields (10) and spreading and straightening gravel (11), using clamps (4) and vertically displaceable spreaders (7). The clamps (4) and the ripper (7) are mounted on a beam (3) which is slidably mounted in the portal (1) parallel to the machine axis. The clamps (4) are fastened to the beam (3) by means of a transverse displacement guide (5) of the clamps (4) relative to the beam (3). The spreader (7) is connected to the beam (3) together with the operator's cab (8) via a turntable (9). The machine travels by the length of the laid track field (10) is to push the ballast (11) back into the track by means of side coulters (6).

Permanent restoration machines

Technical field

The invention solves a railway track restoration machine which replaces several mechanisms hitherto needed for this restoration - the replacement of rails and sleepers.

BACKGROUND OF THE INVENTION

The previously known railway line renewal mechanisms are economical for the renewal of longer track sections. There are two main uses. The recovery train operates continuously by removing old rails from the sleepers and loading those sleepers onto their special wagons. Loosen the ballast bed, level the new sleepers and store the new rails. Reconditioning train is a bulky device and requires long rails to be distributed and stored along the track as well as collection of old rails. In the event of a failure, the defect must be rectified in order to terminate the lockout. · The other way is to use the recovery current, which restores the track by parts - track fields. The regeneration current consists essentially of a treadmill, a gravel spreader, a compactor, a treadmill,. barking machines, railway wagons or bogies for the supply of new, and the removal of excavated track fields and locomotives. The track ripper pulls out the track field and puts it on a railway car or bogie, gravel spreader: adjusts ballast bed and compactor is compacted (not always done) and the chopping machine pulls the gravel back into the basket. Renewal current is very long, training is required from Z / i to gravel and mechanisms are difficult to complete in the event of failure of one of the mechanisms · When bogies are used to feed and move track fields, wheelbase and bogie collection along track by special mechanisms ·

SUMMARY OF THE INVENTION

The aforementioned drawbacks are eliminated by a traction recovery machine according to the invention, which is based on the use of a single machine for mining (tearing) old track fields and loading them on the bogies, rolling up and leveling gravel at the torn track field and storing a new track field. rail field · The ballast is rolled up and settled while moving the old rail field from the machine while moving the new rail field to the machine, when the spreader is lowered into the ballast · After the new rail field is stored pulls the gravel with the side plows back into the track.

This cycle is repeated. When a new track field is laid, this is shaped into a corresponding arc and its precise position is controlled laterally. Thus, the track restoration machine replaces the track field ripper, gravel spreader, track field depositor and the slipping machine. When restoring short sections of the track, the track restoration machine can also be used as a towing vehicle for the supply and removal of track fields. The track restoration machine uses bogies to move the track fields, on which the track fields have been moved, thus eliminating the distribution and collection of bogies. Mechanisms are eliminated and only half of the bogies are needed · Using a trackside recovery machine will reduce the workforce for longer, reduce fuel consumption, eliminate dangerous and time-consuming railing and training mechanisms, and in the event of a failure, ^T the machine replaced with the tracks and thus not prolong the lockout.

DETAILED DESCRIPTION OF THE INVENTION

The track restoration machine consists of a gantry 1 formed of a longitudinal and legs supported on the bogies. A beam 4 is slidably mounted on the gantry 1, provided with the wheel field clamps 4 guided by lines. .11 and the cab 8 by means of a common turntable 2 P ^ro work in both directions · Chassis (or two bogies) £ are provided with side plowshare £ chucks are relative to the beam. ^ Sliding in transverse direction using 2 * guides

Industrial applicability

The track restoration machine according to the invention is advantageous for the restoration of shorter track sections limited by the length of the lock, but can be used for longer sections as well as for the construction of new tracks. that is, for laying new track fields on pre-prepared gravel beds. An important advantage of the track restoration machine is the shaping of the arch and the lateral control of the placement of the new track field, but also the possibility to work in both directions.
