FIELD: construction. ^ SUBSTANCE: accessory for compaction of loose mediums, in particular ballast of rail track, according to the first version, comprises bearing beam and vibration tool fixed on it. Vibration tool represents rod with lower end in the form of compaction trowel, above which there is a ramming plate fixed on rod, besides rod of vibration tool has possibility to make vibratory oscillations from vibration exciter. Rod of vibration tool is installed on axis, which is arranged higher than ramming plate and is transverse relative to rod. Axis is fixed on bearing beam with the possibility of displacement along vertical line, and rod has possibility of rotation relative to axis and/or bearing beam. Accessory for compaction of loose mediums, in particular ballast of rail track, according to the second version, comprises bearing beam and vibration tool fixed on it, which represents rod with lower end in the form of compaction trowel, above which ramming plate is installed. Rod of vibration tool has the possibility to make vibratory oscillations from vibration exciter. Rod of vibration tool is installed on axis arranged higher than ramming plate and transverse relative to rod, which is fixed on bearing beam. Additional element, lower part of which performs function of additional ramming plate, is installed on rod with the possibility of displacement along it. Vibration exciter is fixed on additional element, and rod has the possibility of rotation relative to axis and/or bearing beam. ^ EFFECT: intensification of vibration action at ballast due to reduction of effect of vibration tool oscillations amplitude quenching. ^ 7 cl, 7 dwg |
