Rail stabilizing device and rail power stabilizing vehicle
The invention discloses a track stabilizing device and a track power stabilizing vehicle. The track stabilizing device comprises a vibration exciter, and the vibration exciter comprises a box body, a first group of vibration exciting assemblies and a second group of vibration exciting assemblies, wherein the first group of vibration exciting assemblies and the second group of vibration exciting assemblies are arranged in parallel; each of the first group of excitation assemblies and the second group of excitation assemblies comprises a driving shaft, a left driven shaft and a right driven shaft which are arranged in parallel, and the driving shafts, the left driven shafts and the right driven shafts are vertically and rotatably arranged on the box body; the driving shaft is sleeved with a driving eccentric wheel, the left driven shaft is sleeved with a left driven eccentric wheel, and the right driven shaft is sleeved with a right driven eccentric wheel. When the driving shaft rotates, the driving eccentric wheel, the left driven eccentric wheel and the right driven eccentric wheel generate horizontal excitation force, and longitudinal excitation force generated by the first excitation assembly can counteract longitudinal excitation force generated by the second excitation assembly. It is guaranteed that the vibration exciter only generates horizontal exciting force on the steel rail, the internal structure of the vibration exciter is compact, and the gravity center of the structure is lowered, so that railway ballasts are effectively compacted, and the stability of a ballast bed is improved.
本发明公开了一种轨道稳定装置及轨道动力稳定车，轨道稳定装置包括激振器，激振器包括箱体、相互平行设置的第一组激振组件和第二组激振组件；第一组激振组件和第二组激振组件均包括相互平行设置的主动轴、左从动轴和右从动轴，主动轴、左从动轴和右从动轴均竖直并可转动设置于箱体上；主动轴套设有主动偏心轮，左从动轴套设有左从动偏心轮，右从动轴套设有右从动偏心轮；主动轴转动时，主动偏心轮、左从动偏心轮和右从动偏心轮产生水平激振力，且第一组激振组件产生的纵向激振力能够抵消第二组激振组件产生的纵向激振力。保证激振器对钢轨仅产生水平激振力，及保证激振器内部结构紧凑和结构重心降低，从而有效密实道砟，提高道床稳定性。
