Definitions
- the invention relates to a continuously (non-stop) track-traveling machine for stuffing the cross sleepers of a track with a machine frame supported on bogies arranged at a distance from one another and a tool carrier connected to it via a longitudinal displacement drive and arranged between two bogies for a height-adjustable lifting / leveling unit and at least one height-adjustable tamping unit with tamping tools that can be distributed and vibrated in pairs and submerged in the ballast by means of auxiliary and vibration drives, and a second machine frame of a vehicle connected to the machine frame, on which a plow arrangement which is actuated and height-adjustable via drives is mounted between two chassis.
- a continuously (non-stop) track tamping, leveling and straightening machine of this type is connected - according to DE-OS 38 19 717 by the same applicant or patent owner - in the working direction subsequently to two further machine frames arranged one behind the other and supported on bogies.
- the central machine frame which directly adjoins the tamping machine, is equipped with a height-adjustable center and side plow arranged between two trolleys and the third machine frame with track stabilizers arranged between two trolleys and a sweeping device.
- At the front, projecting end of the track tamping machine there is also a small, adjustable plow plate that can be swiveled to the side per rail.
- each with a driving cabin and in the area of the tamping units with an operator's cabin - machine cluster can be cyclically supported with a gradual advance of the tamping unit, with the same machine cluster also ballast bed profiling with subsequent ballast bed compaction can be carried out by the track stabilizers.
- Another variant of the machine assembly according to this reference is that the continuous track tamping, leveling and straightening machine is only assigned to the plow arrangement with a sweeping device in the working direction, which is provided on the second machine frame and is height-adjustable via a drive.
- this machine assembly requires a prior passage with the plow arrangement for the ballast profiling or the delivery of ballast for the tamping zones before the actual tamping process.
- driving cabs are provided at the end of the two interconnected machine frames, the machine structure extending all the way up to the driving cabin height.
- the object of the invention is to provide a continuously (non-stop) track-moving machine for tamping the transverse sleepers of a track of the type described at the outset, with which better and more economical track tamping and processing of the ballast bedding can be carried out or improved uses can be achieved.
- the invention consists in that in a continuously (non-stop) track-traveling machine of the type described in the introduction, the track tamping machine with its machine frame end, which is at the front in the working direction, is directly connected or articulated at the end to the second machine frame of the vehicle, which is supported by at least one chassis is designed to be coupled.
- continuous processing or profiling of the ballast bed can be achieved in conjunction with an immediately following continuous tamping of the evenly ballastable track as part of a single, common continuous (non-stop) machine passage.
- a track resulting from the uniform track bulkheading can be produced in a particularly economical manner with relatively little human effort and less machine use, and track that is permanently and permanently tamped in a single work passage.
- the driver's cabin located at the front end of the tamping machine provides an uninterrupted, continuous traffic view of the upstream track or a view for precise observation and operation of the plow arrangement for use of the middle plow adapted to the different ballast conditions and / or Side plows guaranteed.
- the advantage of the transmission of high pulling and pushing forces between the tamping machine and the upstream plow vehicle means that it can also be easily integrated into a train set for a quick transfer.
- a preferred further development of the invention consists in the fact that the track tamping machine connected to the upstream second machine frame with the height-adjustable plow arrangement and a plow arrangement which can be acted upon by drives has at its rear machine frame end - in the working direction - with a third machine frame supported by at least one chassis of another vehicle is articulated to be connected or coupled at the end, on which a sweeping device which is height-adjustable via a drive and is preferably connected to a transverse conveyor belt which can be acted upon by a drive is arranged.
- This training with an upstream and downstream vehicle, each connected to devices for ballast bed profiling or reversal, enables rapid ballast transport both immediately before the tamping process and immediately afterwards for even track bulkheading, particularly for the tamping zones, for a qualitatively uniform track underfilling and permanent track position. This also eliminates the need to use a ballast plow after the tamping machine has been used.
- the two machine frames equipped with the plow arrangement or with the sweeping device are designed as trailer vehicles provided with only one chassis.
- Trailer vehicles of this type with a plow arrangement and sweeping device with a particularly simple design, enable advantageous power transmission, in particular to the upstream or downstream vehicle, for the transmission of sufficiently high thrust or tensile forces for continuous and problem-free distribution or reversal of ballast.
- the articulation at the end of the tamping machine enables simple retrofitting of continuously moving tamping machines that are already in use.
- the upstream and, if appropriate, downstream machine frame has a preferably central, projecting support, which is connected to the tamping machine in the region of the respective end-side chassis of the tamping machine via a joint which is preferably effective on all sides.
- a joint which is preferably effective on all sides.
- the two vehicles with the front second machine frame connected to the plow arrangement and the rear third machine frame connected to the sweeping device are located directly in the area of a driving machine arranged at the front or at the rear end of the track tamping machine. or operator's cabin can be articulated or coupled to the middle first machine frame, the two vehicles with the second and third machine frames being designed without a cabin and without a high machine structure or essentially only up to the machine frame level slightly above the associated undercarriage .
- This design of the upstream or downstream vehicle which is the simplest in terms of construction, enables both a continuous unobstructed view of the traffic on the adjacent track and a largely unrestricted view of the upstream plow arrangement, in particular in connection with the immediately adjacent driving or operating cabins of the central tamping machine or the downstream sweeping device or its control and simple operation.
- another particularly advantageous embodiment of the invention is that the one with its own Travel drive and the machine frame equipped with the drive, braking, energy supply and control devices and equipped with two tamping units arranged between two mutually spaced undercarriages and a lifting and straightening unit which is arranged immediately upstream of them in the working direction and is continuously (non-stop) movable as a tamping machine.
- Leveling and straightening machine and as a control vehicle with buffer couplings provided on both ends of the machine frame and that also at least one of the two vehicles - for optionally quickly detachable connection to one another or to one or the other end of the machine frame of the tamping machine - in each case at both ends its machine frame is equipped with buffer couplings.
- a track tamping, leveling and straightening machine designed in this way as a regulating vehicle is particularly suitable - even while avoiding any disruptive influence on the working units arranged between the bogies - for such end-articulation of vehicles with further working units.
- the arrangement of buffer couplings both at the end of the tamping machine and on the additional machine frame enables a connection or uncoupling that can be carried out quickly and if necessary, and despite the upstream and downstream vehicle, an unrestricted integration of the tamping machine into a train set for a quick and safe transfer run is possible .

Furthermore, a and straightening drives 21, 22 height-adjustable and side-adjustable lifting-straightening unit 23 - which can be lowered and moved on the track 6 via two spaced-apart spur gear pairs designed as straightening tools - attached to the displaceable tool carrier 14. This also has lifting rollers 24 and hooks 25 which can be placed on the rails 5. For the longitudinal displacement of the tool carrier 14 together with the tamping unit 19 and the lifting-straightening unit 23, in addition to the drive 18, a travel drive 26 acting on the support and guide undercarriage 16 is provided.
