SPLIT TOOL MECHANICAL VIBRATOR

摘要

A tamping vehicle (10) uses a split tool mechanical vibrator (14) having corresponding front and back vibrator units (28F, 28B) powered by a single motor (30). Sprockets (34) and a synchronous sprocket belt (36) drive front and back units (28F, 28B) to vibrate 180 degrees out of phase. A lubricant carrying belt (70) carries oil to the top of a housing for lubricating and cooling various moving parts. Squeeze cylinders (64) are used to move tamping tools (58) to squeezed in positions by rotating the tamping tools (58) about the same axes as rotation of vibration inducing shafts (32, 40). Independently liftable gauge and field side tamping assemblies allow use at railroad switches and other locations where narrow width tamping is needed. A tamping tool (58) provides easy connection to a tamping tool holder (48) in such a way that two tamping tools (58) may be mounted to one tool holder (48).
