Abstract
A plough to be applied to a machine for rehabilitating a railway track, for performing the operation consisting in displacing the ballast to be renewed. Lateral ejectors are applied to the lower portion of the plough and actuated alternatively for breaking the compact ballast and push the gravel so as to gradually accumulate same on the sides and afford and easy forward travel of the plough for making a relatively deep cutting into which the new ties can be laid without requiring a subsequent sinking thereof. The lateral ejectors are actuated two at a time, one to the right and the other to the left, for compensating side stress. A possible mechanism for actuating the lateral ejectors comprises rockers having unequal arms and actuated by a hydraulic cylinder.
Claims13
A plow for laterally displacing compacted ballast of railway road beds, comprising:
- a vehicle having means for propelling said vehicle along the road bed, a V-shaped plow mounted on said vehicle and having an apex and plow blades which extend at an angle rearwardly and laterally outwardly from the apex of said plow, each of said blades having spaced apertures in lower portions thereof,
- a plurality of ejectors disposed in said apertures and movable transversely of the direction of movement of said vehicle between a retracted position and an extended position in which they project laterally outwardly from said blades, and power means for intermittently moving said ejectors laterally between said retracted position and said extended position as said plow is moved forwardly by said vehicle.
