TAMPING UNIT FOR TRACK TAMPING MACHINES FOR TAMPING TWO IMMEDIATELY ADJACENT SLEEPERS

摘要

A tamping unit (7) for track tamping machines for tampingtwo immediately adjacent sleepers of a track is provided withtwo pairs, mounted one following the other in the longitudinaldirection of the machine on a vertically adjustable toolcarrier (14,15), of outer and inner tamping tools (10-13)respectively connected to an eccentric shaft (17,26) by way ofa squeeze drive (18,25). One of the outer tamping tools (13)arranged on either side of the inner tamping tools (10,11) -with respect to the longitudinal direction of the machine - isdesigned so as to be independently vertically adjustablerelative to the other tamping tools (10,11,12) by means of aseparate vertical adjustment drive (20). This independentlyvertically adjustable outer tamping tool (13) is mounted on aseparate, second tool carrier (15) and is connected by way ofthe squeeze drive (18) to a separate eccentric shaft (17).The associated tool carrier (15) is mounted for verticaladjustment on a vertical guide (19) and is connected for thevertical adjustment to the separate vertical adjustment drive(20).
