Rail work wheel and forced vibration device for tightening railroad base base

摘要

PROBLEM TO BE SOLVED: To provide a road/rail working vehicle for compacting a railroad roadbed, which can reliably compact a railroad roadbed part to enough depth.;SOLUTION: A road/rail working vehicle 1 for compacting a railroad roadbed has a road/rail dump 10 and forced vibration equipment 20 mounted thereon. The forced vibration equipment 20 comprises a frame 30 fixed to a loading platform 11 of the road/rail dump 10, a unit supporting part 40 supported by the frame 30, and a forced vibration unit 50 supported by the unit supporting part 40 in a state of being movable to a retracted position 50A and a rising position 50B. The forced vibration unit 50 comprises a vibration stake 51, an electrically-driven vibration part 70 giving vibration to vibration stake 51, and a vertical sliding mechanism 80 which forces vibration stake 51 into the axial direction in the vibrational state. In comparison with using a general vibration machine, the long vibration stake 51 can be press-fitted into the deep position and the compaction of a railroad roadbed part 120 can be performed reliably.;COPYRIGHT: (C)2012,JPO&INPIT
