Track-levelling tamping machine with tamping and stabilising aggregate

摘要

Movable track-tamping, levelling and straightening machine (1) with a chassis frame (6) and a tamping aggregate (13) which has vibratable tamping tools (22) which can be displaced in relation to one another in pairs, and with a track-lifting and straightening aggregate (14) arranged in front of the tamping aggregate (13). Also provided is an arrangement (9) for tool control and a levelling reference system (10) as well as a track-stabilising aggregate (36) which, via its own track-movable wheel sets, can be brought positively into engagement with both rails of the track. Its tool frame can be set in horizontal oscillation via vibrators (40) and can be acted upon with vertical loading forces via cylinder/piston drives (37). The tamping and track-lifting and straightening aggregates (13, 14) are arranged with the associated drives as a working unit (15) on their own common tool support frame (16). In this case, the tool support frame (16) can with one end be supported on the track via an individual bogie (17) which is designed as a support and guide member and serves as a free leading axle and is with its other end connected for support to the chassis frame (6) in an articulated manner, the track-stabilising aggregate (36) being arranged between the working unit (15) and the next machine bogie (2) arranged downstream in the working direction of the machine.
