Tamping device for track tamping machine
The invention relates to a tamping device (W1) for a track tamping machine (A), comprising a plurality of tamping tool pairs (7, 8) which are arranged on a support (4) and are designed as rockers (13), said support being guided in a tamping device frame in a height-adjustable manner, the lower-end pick ends (10) of the tamping tool pairs for insertion into the ballast bed are driven opposite each other by means of a linear oscillating drive (2) and can be hydraulically fed relative to each other. In order to provide advantageous tamping properties, it is proposed that every at least two tamping devices (W1H, W1V) are arranged one behind the other along a tamping device longitudinal axis (L) parallel to the longitudinal direction of the track tamping machine, and that at least two, preferably four tamping devices, are arranged next to one another transversely to the tamping device longitudinal axis (L), according to the invention, two planes (1) spaced apart from each other at a rail-sleeper distance and arranged perpendicular to the longitudinal axis (L) of the tamping device on both sides of the associated support (4) support a working space (R) in which the rocker (13) and the tamping tool pair (7, 8) depict a movement trajectory during an oscillating feed movement (14) by means of the pick end (10), the linear oscillation drives (2) of the tamping device (W1) are arranged one on top of the other in an oscillation plane extending transversely to the plane (1) and are arranged at least approximately parallel to the longitudinal axis (L) of the tamping device at an angle to the working space (R), and wherein the linear oscillation drives (2) of the tamping device (W1) are arranged in the oscillation plane extending transversely to the plane (1).
在此建议一种用于轨道捣固机械(A)的捣固设备(W1)，其具有安置在支架(4)上的、设计为摇杆(13)的多个捣固工具对(7、8)，所述支架在捣固设备框架内可调节高度地导引，这些捣固工具对的用于插入碎石道床中的、下端的鹤嘴锄端部(10)通过线性振荡驱动器(2)被彼此相反地驱动并且能够相对彼此液压地进给。为了提供有利的捣固特性，在此建议，每至少两个捣固设备(W1H、W1V)沿着平行于轨道捣固机械纵向的捣固设备纵轴线(L)依次地布置，并且至少两个、优选四个捣固设备横向于捣固设备纵轴线(L)并排地布置，其中，针对每个捣固设备(W1)，两个以钢轨轨枕间距相互间隔的、在所属的支架(4)两侧垂直于捣固设备纵轴线(L)布置的平面(1)撑起作业空间(R)，所述摇杆(13)和捣固工具对(7、8)在所述作业空间内通过所述鹤嘴锄端部(10)在振荡地进给运动(14)过程中描绘出运动轨迹，该运动轨迹的包络线仅位于所述作业空间(R)中，并且其中，捣固设备(W1)的线性振荡驱动器(2)在横向于所述平面(1)延伸的振荡平面内彼此相叠地布置，并且至少几乎平行地相对于捣固设备纵轴线(L)倾斜地布置。
