Definitions

  • the invention relates to a tamping machine for tamping under sleepers of a track, with working machine parts that can be moved on rail carriages and are arranged one behind the other in the machine's longitudinal direction and coupled to one another, a supply part with a machine frame and a working part with one, at least one, height-adjustable tamping unit, and a track lifting direction.
  • Machine frame having an aggregate, both the supply part and the working part being self-propelled, the supply part being able to be moved continuously in the tamping operation and the working part being discontinuously movable, for which purpose the supply part and the working part are connected to one another via flexible supply lines, in particular for hydraulics, pneumatics and electrics, and travel drives from Supply part and working part can be controlled accordingly.
  • a control device makes it possible to move the control and control vehicle along the track at an approximately constant speed, regardless of the forward movement of the work vehicle, in particular constantly and continuously, so that the devices for monitoring, operation and control arranged in the control and control vehicle of the devices and tools as well as the operator is not influenced by the possibly gradual forward movement of the work vehicle and the impacts, stresses, etc. exerted on the machine by the tools or devices.
  • the traction slip can make it difficult to position the working part precisely.
  • the AT 378 387 B and the DE 34 09 849 A1 concern tamping machines with a machine concept in which the supply part is self-propelled and in which the working part is positively guided, i.e. not self-propelled.
  • the working part is positioned relative to the supply part via a piston-cylinder unit which is arranged between the working part and the supply part.
  • Another tamping machine that can be moved continuously during work is, for example US 6,705,232 known.
  • the advantage of continuously working tamping machines is that the entire machine, with its large mass, does not have to be stopped at every threshold to be tamped and then accelerated again. This increases the working speed of the machine compared to cyclically working machines and also reduces the accelerations affecting the machinist.
  • the cyclical right-of-way from threshold area to threshold area is limited to the satellite carrying the working units and arranged under the tamping machine, which is designed to be longitudinally displaceable relative to the main frame of the machine.
  • Such a machine is also from the AT401943B and the DE 3409849 A1 known.
  • Tamping units fix the position of a track during maintenance work. This is done using so-called tamping tools Tamping picks that dip into the ballast next to the sleepers and compact the ballast below the sleeper via a linear closing movement that is superimposed by a compaction vibration.
  • the track is lifted and straightened into a predetermined target position by a lifting and straightening device and held in this position during tamping.
  • the position of the track during tamping is measured using measuring cars and control devices and is kept at target by comparing it with target values from a track position computer.
  • tamping machines that are specialized in tamping switches, with divisible tamping units that can be adjusted transversely to the machine's longitudinal direction with regard to their working position - so-called splithead units, with additional lifting devices for the branching strand, with swiveling compaction picks, with the tamping units being able to rotate about a vertical axis in the transverse center of the machine etc. and there are tamping machines that are preferably built for line tamping. There are also single-sleeper and multi-sleeper tamping machines. Multi-sleeper tamping machines stuff several sleepers at once in one work cycle.
  • chord pitch of the working chords which scan the actual track geometry and are stretched between a front, a middle and a rear measuring car that can be moved along the track, can be changed during work.
  • the front and rear measuring carriages, between which the measuring chord is stretched are connected to the outer, continuously moving main machine frame, while the measuring car, which carries the sensors for scanning the track geometry in relation to the chords, is located on the satellite, the position of which changes cyclically with respect to the main machine frame.
  • the track geometry error reduction ratio changes when the machine operates in compensation mode.
  • the error reduction ratio depends on the ratio of the long chord section to the short chord section. The larger this ratio is, the more track errors are reduced. In conventional continuous tamping machines, this ratio changes disadvantageously during the tamping process - the ratio becomes smaller as the duration of the tamping process increases.
  • Another disadvantage is the additional cost of material and weight due to the size of the outer, continuously moving front machine part. Overall, the total necessary mass and drive power of the machine are large.
  • the invention is therefore based on the object of avoiding the disadvantages mentioned above and of creating a tamping machine of the type described at the beginning, with which better results can be achieved with regard to the target track geometry to be produced.
  • the invention solves the problem in that the working part is connected to the supply part to support the discontinuous travel drive of the working part via at least one hydraulic drive/brake cylinder, which is equipped with a position sensor for detecting the respective piston position in the cylinder.
  • the working part is connected to the supply part to support the discontinuous travel drive of the working part via at least one hydraulic drive/brake cylinder.
  • the hydraulic cylinders can be equipped with a position sensor that transmits the respective piston position in the cylinder to a machine control system.
  • This hydraulic drive can be used both for accelerating the working part and for braking when executing cyclic right-of-way.
  • the course of the approach ramp and the braking ramp can be precisely specified using proportional control valves and corresponding control electronics.
  • the hydraulic cylinder is preferably depressurized and therefore switched to floating.
  • the hydraulic drive/brake cylinder is provided in addition to the travel drives of the supply and working parts. Both the supply part and the working part are self-propelled, with the supply part being able to move continuously in tamping mode and the working part being able to move discontinuously.
  • the tamping machine is equipped with at least one hydraulic drive/brake cylinder in addition to the travel drives in particular transmits acceleration and braking forces, and thus allows shorter cycle times, which are limited downwards by drive slip of the cyclically moving working part. Because the hydraulic drive/brake cylinder is equipped with a position sensor for detecting the respective piston position in the cylinder, precise positioning of the working part with respect to the supply part or at a working position with a corresponding control device is always possible.
  • the working part and the supply part can each be moved independently of one another on a track with their own travel drive.
  • the working part carries at least one tamping unit that can be lowered and raised as well as a track lifting and straightening unit, a work cabin and a driving cabin at the front.
  • the supply part of the machine carries the heavy components, in particular the diesel engine, the diesel tanks, hydraulic tank, distribution gearbox and possibly integrated other work units that can be operated in continuous mode such as dynamic stabilization units, gravel plows, gravel sweeping system, steep conveyor belt and silo etc. and a driving cabin at the rear .
  • a large part of the mass of an outer machine frame surrounding the satellite which is otherwise necessary in known continuously operating machines, can be eliminated, whereby a large amount of weight can be saved.
  • measuring cars assigned to the working part constant distances between the measuring cars can always be achieved, which increases the precision and accuracy of correcting the track geometry. Namely, during tamping, the error reduction ratio remains constant and large. This results in better error correction by the machine. Overall, the overall mass of such a machine is reduced compared to the prior art, which in turn results in lower manufacturing and operating costs and a smaller ecological footprint.
  • the distance sensor which measures the distance between the supply and working parts, can be used to automatically coordinate the continuous advance speed and cyclic advance speeds. This also allows collisions between the supply and working parts to be avoided.
  • the at least one hydraulic drive/brake cylinder can be controlled to support the discontinuous travel drive of the working part depending on the distance between the working part and the supply part and the absolute position data, in particular GPS data of the tamping machine.
  • Heavy machine components namely drive motor, fuel tank, hydraulic tank and transfer gearbox are preferably provided on the supply part.
  • the working part can be equipped with measuring carriages connected by tendons, a front, a middle and a rear measuring carriage, the tendons having a fixed chord pitch ratio between the measuring carriages (16, 11, 17) and constant chord lengths.
  • At least one of the drives of the working part and the supply part is in particular equipped with a travel drive. If necessary, two or more drives can also be equipped with a travel drive if this is necessary due to braking or acceleration forces.
  • the working part and supply part can be coupled with an automatic central quick coupling.
