Definitions

  • the invention relates to a tamping machine for tamping sleepers of a track, with working machine parts that can be moved on rail chassis, are arranged one behind the other in the longitudinal direction of the machine and are 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 straightening Machine frame having a unit, with both the supply part and the working part being self-propelled, with the supply part being able to move continuously in tamping operation and the working part being moveable discontinuously, for which purpose the supply part and 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 monitoring vehicle independently of the forward movement of the work vehicle, in particular constantly and continuously, along the track at an approximately constant speed, so that the devices for monitoring, operation and control arranged in the control and monitoring vehicle of the devices and tools as well as the operator is not influenced by the possibly step-by-step forward movement of the work vehicle and the impacts, stresses, etc. exerted on the machine by the tools or devices.
  • Drive slip can make exact positioning of the working part difficult.
  • Another tamping machine that can be continuously moved during work is, for example, by U.S. 6,705,232 known.
  • the advantage of the 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 must then be accelerated again. This increases the working speed of the machine compared to cyclically working machines and also reduces the accelerations acting on the machine operator.
  • the cyclic advance from threshold area to threshold area is limited to the satellite that carries the working units and is arranged under the tamping machine and 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 a maintenance measure. This is done using tamping tools, so-called tamping picks, which dip into the ballast next to the sleepers and compact the ballast under the sleeper using a linear closing movement that is superimposed by a compaction vibration.
  • the track is lifted and straightened by a lifting and straightening device into a predetermined target position and held in this position during the tamping.
  • the position of the track is measured during the tamping by means of measuring wagons and control devices and is kept on target by comparison with the target values of a track position computer.
  • tamping machines that are specialized in tamping points, with divisible tamping units that can be adjusted transversely to the longitudinal direction of the machine in terms of their working position - so-called split-head units, with additional lifting devices for the branching line, with swiveling compacting picks, with the tamping units being able to rotate about a vertical axis in the transverse center of the machine and the like, and there are tamping machines that are primarily built for line tamping.
  • Known satellite frames ( U.S. 6,705,232 ) run on the rails by means of a chassis, which is equipped with brakes and a drive acting on the wheels.
  • the disadvantage of the known designs is that the working satellite is guided in a main engine. The larger the satellite, as in the case of multi-sleeper tamping machines, the larger and heavier the main engine enclosing the working satellites.
  • chord pitch of the working chords which scan the actual track geometry and which are stretched between a front, a middle and a rear measuring carriage that can be moved on the track, is variable during work. That is, the front and rear measurement carriages, between which the measurement chord is stretched, are connected to the outer continuously moving main machine frame, while the measurement carriage, which carries the sensors for scanning the track geometry in relation to the chords, is located on the satellite whose location changes cyclically with respect to the main machine frame.
  • chord ratios changes the track geometry error reduction ratio when the machine is operating in the compensation mode.
  • the error reduction ratio depends on the ratio of the long chord segment to the short chord segment. The larger this ratio is, the more track errors are reduced. In conventional continuous tamping machines, this ratio changes disadvantageously during the tamping process - namely, the ratio becomes smaller with increasing duration of the tamping process.
  • Another disadvantage is the additional cost of material and weight, due to the size of the outer continuously moving front machine part.
  • 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 outset with which better results can be achieved with regard to the desired track geometry to be produced.
  • the invention solves the task 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 is connected, 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.
  • This hydraulic drive can be used both to accelerate the working part and to brake when performing the cyclic advance.
  • the course of the start-up ramp and the braking ramp can be precisely specified using proportional control valves and corresponding control electronics.
  • the hydraulic cylinder is preferably depressurized and thus 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, whereby the supply part can be moved continuously and the working part can be moved discontinuously during tamping operation.
  • the tamping machine is equipped with at least one hydraulic drive/brake cylinder in addition to the travel drives, which in particular transmits acceleration and braking forces, and thus shorter ones Cycle times allowed, which are limited downwards by a 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 is always possible with a corresponding control device.
  • the working part and the supply part can each be moved independently of one another on a track with their own traction 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 driver's cabin at the front.
  • the supply part of the machine carries the heavy components, in particular the diesel engine, the diesel tanks, hydraulic tank, transfer case and possibly other integrated work units that can be operated in continuous mode such as dynamic stabilizing units, gravel plows, gravel sweeping system, steep conveyor belt and silo etc. and a driver's cab 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 omitted, as a result of which a large amount of weight can be saved.
  • the measuring carriage assigned to the working part constant distances between the measuring carriages can also always be realized, which increases the precision and accuracy of the correction of the track geometry. Namely, during the stuffing, the error reduction ratio remains constant and large. This achieves 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, the continuous advance speed and cyclic advance speeds can be automatically coordinated with one another. This also allows collisions between the supply and working parts to be avoided.
  • the at least one hydraulic drive/brake cylinder to support the discontinuous travel drive of the working part in
