FIELD: railroad bed compaction. SUBSTANCE: aim is to increase reliability of working organ. Working organ of sleeper tamping machine has longitudinal beam 2 mounted on frame 1 of sleeper tamping machine, on which vibration plate 4 is suspended with compacting wedges 5 and 6, beam turning drive that has front cantilever 17 and rear cantilever 18 mounted on columns 21 with capability of vertical motion and turning, and telescopic tie-rod 23 hinged to longitudinal beam. Working organ has guiding rod 9 mounted telescopically with one end in pit 10 in end part of longitudinal beam 2 with capability for longitudinal motion by force cylinder 11. Longitudinal axes of cylinder 11 and beam 2 are parallel. EFFECT: increased reliability of working organ. 5 dwg |
