    专利说明:

    The invention relates to a Stopfaggregat for Unterstopfen thresholds of a track, with a height adjustable mounted on an aggregate frame pimple carrier, on each of which by a hydraulic, a cylinder axis and connected to a vibratory feeder Beistellantrieb are mounted to each other pivotable tamping. Stopfaggregate to Unterstopfen thresholds of a track are already widely known, such. For example, by US 4,240,352, AT 339,358, EP 0 331 956 or US 4 068 595. The vibrations of the vibration exciter acting on the tamping picks can be generated either by an eccentric shaft or by hydraulic pulses in a linear drive which at the same time also provides the auxiliary movements the tamping pick performs.
    The object of the present invention is now to provide a tamping unit of the type mentioned, with which an improved vibration of the tamping pick is possible.
    This object is achieved with a tamping unit of the generic type by the features cited in the characterizing part of the main claim.
    Such a vibration exciter on a hydraulic basis has the advantage that functionally a clear separation between the vibration generation on the one hand and the Beistellbewegung for stuffing tamping on the other hand he is targetable. In addition, a simplified control effort for vibration generation is possible.
    Further advantages of the invention will become apparent from the dependent claims and the drawing description.
    In the following the invention will be described in more detail with reference to embodiments shown in the drawing. 2 shows a simplified view of a vibration exciter with a hydraulic circuit diagram, and FIG. 5 shows a further variant of a side drive.
    An illustrated in Fig. 1 Stopfaggregat 1 for Unterstopfen sleepers of a track has two tamping pickles 2, which are each with the aid of a Beistellantriebes 3 for a ballast compaction, movable like a pair of pliers. Each tamping pick 2 is mounted pivotably about a pivot axis 4 on a pommel carrier 6, which is height-adjustable relative to an aggregate frame 5. Each a cylinder axis 7 having Beistellantrieb 3 is assigned a hydraulically based vibration exciter 8 for generating a Beistellbewegung the tamping 2 superimposed vibrations. The Beistellantrieb 3 is pivotally mounted about a bearing axis 9 on the pimple carrier 6.
    A shown in Fig. 2 cross-section of the Beistellantriebes 3 shows a cylinder axis 7 to the coaxially arranged inner cylinder 10 of the vibrator 8, which also serves in this particular embodiment of the invention as - composed of hydraulic cylinder and cylinder piston - Beistellantrieb 3. The inner cylinder 10 (or the auxiliary drive 3) is slidably mounted in an outer cylinder 12 via sliding surfaces 11 in the axial direction 7.
    Between two in the direction of the cylinder axis 7 (axial direction) spaced sliding surfaces 11 an annular recess 13 in the outer cylinder 12 is provided. A spacer ring 15 dividing this annular recess 13 into two fluid channels 14, which are spaced apart from one another in relation to the axial direction 7, is connected to the inner cylinder 10. The two fluid channels 14 are alternately hydraulically actuated by supply lines 16 for vibratory excitation of the inner cylinder 10 (i.e., the auxiliary drive 3) (the supply lines required for the auxiliary movement of the auxiliary drive 3 are not shown for the sake of simplicity).
    With the indicated bearing axis 9 of the outer cylinder 12 of the vibration exciter 8 is directly (and thus the Beistellantrieb 3 indirectly) hinged to the pimple carrier 6. The alternating admission of the two each connected to the supply lines 16 fluid channels 14 carried by a phase-shifted by 180 ° double-piston pump 17th
    A vibration amplitude of the tamping pick 2 is defined by a stroke volume H of the double-piston pump 17 and the volume of the two fluid channels 14. A change in the stroke volume H is possible by adjusting the Exzenterweges on the double piston pump 17. The vibration frequency of Stopfpickel 2 corresponds to the stroke frequency of the Doppei piston pump 17 (or speed n of an eccentric shaft). The vibration frequency can be adjusted by changing the eccentric shaft speed from 0 to 60 Hz. Stroke and return stroke of the inner cylinder 10 (or Beistellantriebes 3) is effected by the 180 ° phase-shifted double-piston pump 17. The oscillation amplitude of the tamping 2 as a function of impact force is adjustable by a proportional pressure relief valve 18. By this optionally also the stuffing picking vibration can be interrupted without having to switch off the drive of the double piston pump 17.
    In the embodiment variant of a "combination cylinder" shown here, the functions "stuffing tip provision" and "stuffing pitch vibration" can be combined in a compact design as well as in compliance with industry standard installation dimensions of auxiliary cylinders in tamping units.
    The outer cylinder 12 of the vibration exciter 8 has in the region of the sliding surface 11 of the spacer ring 15 an outlet opening 19 for emerging from the two fluid channels 14 leak oil, which is supplemented via a feed line 20. Thus, the intensively heating oil can be continuously renewed by the vibrations.
    As can be seen in a variant represented by FIG. 3, the two mutually facing fluid channels 14 of the two vibration exciters 8 on the one hand and the two fluid channels 14 facing away from each other can be acted upon by a common supply line 16 on the other hand. This creates a pressure balance between the vibratory drives. Thus, the vibration amplitude is proportional to the load pressure (vibration resistance). As a result, a so-called asynchronous plugging is produced (with the effect that a higher amplitude is established on the side with lower vibration resistance).
    According to an embodiment variant shown in FIG. 4, one of the two supply lines 16 of the vibration exciter 8 can be acted upon by the double piston pump 17 and the other each by a hydraulic accumulator 21. This designed as a diaphragm or piston accumulator hydraulic spring is defined by the gas filling and preload pressure.
    In principle, of course, any known type of generation of a pulsating fluid flow for the vibration exciter 8 can be used. It could e.g. Instead of the piston pump, a preferably directly attached to the vibration exciter 8 Proportional valve are provided.
    According to the variant shown in FIG. 5, the spacer ring 15 is connected to the outer cylinder 12, while the fluid channel 14 is provided in the inner cylinder 10 or Beistellantrieb 3.
