Definitions

  • the invention relates to a method and a Stopfaggregat for undercutting a track according to the cited in the preamble of claims 1 and 5 features.
  • EP 1 653 003 A1 is a generic Stopfaggregat known, wherein To stuff a track tamping pick in pairs to each other to be moved. This additional movement for ballast compaction is carried out with the aid of a hydraulically actuated auxiliary cylinder. The linear addition movement is hydraulically superimposed with a vibration to allow easier penetration into the ballast and improved compaction.
  • the object of the present invention is to provide a method and a tamping unit of the type mentioned, with which an improvement of the hydraulic vibration generation is possible.
  • an optimization of the parameters required for vibration generation is possible independent of the additional movement of the tamping picks.
  • An improvement, in particular with regard to the energy balance, can be achieved if the vibration piston is effective as a spring-mass system. With such an energy storage of the high hydraulic energy consumption required per se for the generation of vibrations is significantly reduced. Another resulting advantage can be seen in a lower noise emission.
  • Fig. 1 a simplified side view of a tamping machine with a Stopfaggregat for undercutting a track
  • Fig. 2 an enlarged view of a Beistellantriebe tamping unit
  • Fig. 3 to 6 depending on a variant of an inventive Beistellantriebes.
  • the apparent tamping machine 1 has a machine frame 4 which can be moved by rail carriages 2 on a track 3. Between the two rail bogies 2 a height adjustable by a drive 5 Stopfaggregat 6 for Unterstopfen thresholds 7 is arranged.
  • tamping unit 6 has in a Beistellterrorism 8 in pairs about a pivot axis 9 to each other movable, connected at a lower end 10 with stuffing pickles 11 Tamping 12 on. These are connected at an upper end 13 each with a hydraulic Beistellantrieb 14, which are designed both for carrying out the linear Beistell Gay 8 and one of these superimposed vibration. Both stuffing lever 12 and the Beistellantriebe 14 are mounted on a height adjustable by the drive 5 relative to an aggregate frame 15 carrier 16.
  • Beistellantriebe 14 shown in detail each have one along an axis 17 of a Beistellzylinders 18 movable Beistellkolben 19 and a Beistellkolbenstange 20 connected thereto.
  • these are hydraulically moved from left to right in order to execute the linear auxiliary movement movement 8 (see in this regard the hydraulic lines 21 with a valve 22 or a pressure limiting valve 23.
  • a vibration piston 24 designed to generate the vibrations is arranged in addition to the auxiliary piston 19 provided for the auxiliary movement 8. This is in accordance with the two variants 3 and 4 each disposed between the side piston 19 and a cylinder bottom 25 of the Beistellantriebes 14.
  • a piston rod 26 connected to the vibrating piston 24 is arranged in a cylinder ring 27 fixed to the cylinder bottom 25 for displacement along the axis 17 of the auxiliary cylinder 18.
  • the vibrating piston 24 contacting energy storage 29, preferably mechanical springs 30, arranged for the exercise of parallel to the axis 17 effective forces.
  • a formed by the cylinder bottom 25, the cylinder ring 27 and the piston rod 26 of the vibrating piston 24 oil chamber 31 is acted upon by a hydraulic line 32 for generating a first oscillating motion 33 with high pressure.
  • a hydraulic line 32 for generating a first oscillating motion 33 with high pressure.
  • an end position damping 34 is arranged on the vibrating piston 24 and / or on the Beistellkolben 19 .
  • the Beistellkolben 19 is offset together with the Beistellkolbenstange 20 by corresponding position of the valve 22 and actuation of a Beistell- and vibration piston 19, 24 limited oil chamber 44 in motion, which leads to each other in pairs opposite tamping 11 in the context of Beistellterrorism 8 (s. Fig. 2 ).
  • the constant amplitude oscillation superimposed on this linear addition movement is generated by the vibration piston 24 which can be moved independently of the supply piston 19.
  • the cushioning 34 prevents vibrating and Beistellkolben 24, 19 have abrupt contact.
  • the valve 35 When the valve 35 is reset, a connection to a storage container is established. In this position, a floating position is possible. As a result, the spring 30 can now reset the vibrating piston 24 (with a movement in the direction of the cylinder bottom 25) and the hydraulic oil is discharged into the storage container.
  • the task of the energy store 29 is thus taken over by the mechanical spring 30 (alternatively, the energy store 29 can also be formed by a bubble store or the like).
  • the vibration piston 24 and the springs 30 thus form a power conservation system 36 in the form of a spring-mass system. Ideally, the system 36 is operated near the resonant frequency of the spring - mass oscillator. With the pressure relief valve 23 a Beistelldruck for the Beistellieri and thus a dynamic counter cushion is constructed.
  • the vibrating piston 24 is connected by the mechanical springs 30 with a piston surface 37 of the Beistellkolbens 19.
  • the springs 30 could also be omitted. However, this would require a higher hydraulic pressure to produce the vibration and thereby degrade the efficiency.
  • the Beistellkolben 19 and the Beistellkolbenstange associated with this 20 has a preferably coaxial with the axis 17 extending bore 38 for carrying out a first oscillatory movement 33 of the vibrating piston 24 generating vibration pulse (see also Fig. 5 . 6 ).
  • the vibration is generated by the valve 35, wherein the two pistons 19, 24 are moved apart.
  • the Beistellterrorism the Beistellkolbens 19 is activated by the valve 22 and in an oil chamber 45 (limited by the vibrating piston 24 and the cylinder bottom 25) executed.
  • the second (the first opposite) swinging motion is in turn activated by the energy conservation system 36 composed of vibrating piston 24 and springs 30.
  • the vibrating piston 24 is formed in each case as an opening 40 for carrying the Beistellkolbenstange 20 having ring 41.
  • the connected to the vibrating piston 24 mechanical springs 30 are on a piston rod side piston surface 42 of the side piston 19 (s. Fig. 5 ) or attached to a piston rod-side cylinder bottom 43 of the Beistellantriebes 14 (s. Fig. 6 ).
  • the vibration generation is carried out as in the embodiment according to Fig. 4 in a by vibrating and Beistellkolben 24, 19 limited, the springs 30 containing oil chamber 44th
  • control or regulation of the present invention is carried out by simple and robust sensors and the necessary variables for the control or control are determined by means of model predictive system (observer). From known, easily measured physical quantities or manipulated variables, the unmeasured magnitudes of an observed reference system are determined.
