Definitions

  • the invention relates to a tamping machine for tamping sleepers on a track, with a machine frame that can be moved on rails and extends in the longitudinal direction of the tamping machine, and a satellite (3) that is arranged between the rails and can be moved on the track between the rails via a chassis and a travel drive, which is guide-connected via a satellite longitudinal guide to the machine frame and which has a height-adjustable tamping unit with respect to the satellite and a track lifting straightening unit between the chassis and the satellite longitudinal guide.
  • Tamping machines of this type work continuously with stuffing/working satellites, here satellites for short.
  • the tamping machine travels at a constant speed during work, while the integrated satellite with tamping units, lifting and straightening device and measuring carriage moves discontinuously from tamping area to tamping area and straightens the track and tamps the sleepers.
  • Such a tamping machine that runs continuously during work is known, for example, from US Pat. No. 6,705,232.
  • the advantage of this type of tamping machine is that the main machine with a significantly larger 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 the accelerations acting on the machinist are also reduced.
  • the cyclic advance from threshold area to threshold area is limited to the satellite carrying the working units, which is designed to be longitudinally displaceable relative to the main frame of the machine. Nevertheless, the satellite mass is around 1/4 to 1/3 of the total machine mass.
  • Such a machine can also be found in AT401943B.
  • 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 movements of a tamping unit include the vertical immersion of the tamping tines into the ballast, the side movement in which the tamping tine ends are closed to one another and the superimposed dynamic vibration which causes the actual compaction of the ballast grains.
  • hydraulic cylinders for the adjustment movement, which are connected via connecting rods to a vibration shaft with eccentricity and which superimpose the vibratory oscillation on the adjustment movement (AT 369455 B).
  • These vibration shafts and connecting rods are mounted on roller bearings that regularly require expensive maintenance.
  • Other known solutions use a combined linear vibration generation and auxiliary movement via hydraulic cylinders.
  • Tamping work is a costly operational hindrance, which is why it is important for the tamping machines to work as efficiently as possible.
  • the working speed is particularly important when tamping the line. Higher working speeds or line performance also require shorter cycle times, which i. In general, this can only be achieved by moving the satellite from one tamping area to the next more quickly, with the associated greater energy requirement for accelerating or decelerating the tamping satellite.
  • the satellite frame rests on a chassis, which is equipped with block or disc brakes and a drive that drives the wheels works, is connected.
  • the disadvantage of such conventional friction brakes is that a large part of the kinetic energy is released unused into the environment in the form of heat.
  • the invention is therefore based on the object of avoiding the disadvantages mentioned and of enabling an increase in energy efficiency.
  • the invention solves the problem in that the satellite is assigned a hydraulic recuperation brake that counteracts the travel drive.
  • the kinetic energy when braking the satellite is converted into hydraulic energy and preferably stored with the help of hydraulic accumulators.
  • This stored potential energy can subsequently be reused, either by feeding the energy into a hydraulic network, by using it to reverse the cylinder or for the traction drive, or the like brake hydraulically.
  • the recuperation brake can brake the satellite via at least one brake cylinder, which acts on the satellite at one end and on the machine frame at the other end.
  • the travel drive and the recuperation brake comprise at least one common double-acting cylinder, the first cylinder chamber of which is assigned to the travel drive and the second cylinder chamber of the recuperation brake.
  • At least one control valve can be provided for setting a course of a braking ramp of the satellite, which controls or regulates a hydraulic fluid outflow from the cylinder space assigned to the recuperation brake.
  • At least one hydraulic accumulator is preferably provided for storing energy recuperated with the recuperation brake.
  • the recuperation brake can be connected via a valve to a hydraulic on-board network, in particular the travel drive.
  • the recuperation brake can be connected via a valve to a hydraulic vehicle electrical system for the purpose of supporting the hydraulic drive of the tamping units and/or lifting and straightening units.
  • At least one hydraulically operated brake cylinder is provided between the satellite and the machine frame, with the brake cylinder being connected directly to the machine frame and satellite or, if arranged between the front end of the satellite and machine frame, also exclusively rigidly connected to one of the two frames.
  • the stroke of the brake cylinder is less than a maximum displacement path of the satellite, and the return of the brake cylinder to the starting position (during the tamping process) takes place hydraulically, preferably with the previously stored braking energy.
  • the energy should be stored in a very short time and then be available for other hydraulic movement functions within the cycle time.
  • the invention can also be used to achieve high working speeds with short braking times and with the associated high braking forces that are required which enable an effective and precise delay of the satellite's right-of-way movement.
  • Gases are used to store energy in hydraulic accumulators, which are separated from the pressure fluid by a separating element (diaphragm, bladder or piston). The energy can be stored and released again in a very short time.
  • the course of the braking ramp, and thus the charging process of the hydraulic accumulator, can be specified using proportional control valves or servo valves in conjunction with the appropriate control electronics.
  • the back pressure in the bladder accumulator is used to decelerate the satellite, which is charged by the moving mass during braking.
  • the stored hydraulic power is available to the drive train for the next acceleration process and/or other hydraulic movement functions--for example, auxiliary movement or lifting movement of the tamping unit, which run cyclically before the next satellite braking process.
  • the main advantages of the invention are the increase in energy efficiency, the increase in working speed and the reduction in the required drive power.
  • a further advantage consists in being able to position the satellites more precisely in relation to the immersion position of the tamping units above the sleepers by means of the controllable braking effect.
  • Show it 1 shows a schematic representation of a continuously operating tamping machine 1 with satellites 3 and brake cylinder 4 in a side view, FIG.
  • the satellite 3 is connected directly to the machine frame 14 and satellite 3 via at least one brake cylinder 4 assigned to a recuperation brake B, with a travel drive F accelerating the satellite 3 within an intended displacement range A between the rail chassis 9 and the brake cylinder 4 accelerating the satellite 3 within the displacement range A delayed.
  • the piston rod of the brake cylinder 4 located in the pressureless floating position can gradually move back into the starting position.
  • the brake cylinder 4 can also be rigidly connected exclusively to one of the two frames 14, 3, provided that this is arranged between the front end of the satellite 3 and the machine frame 14. In the latter embodiment, the stroke of the brake cylinder 4 is less than a maximum displacement path A of the satellite.

If necessary, energy stored in the hydraulic accumulator 22 can also be applied to the brake cylinder for pushing the satellite 3 back via the control valve 21 .
