VIBRATOR FOR DISCHARGE OF LOOSE LOADS FROM OPEN-TOP CARS Russian patent published in 2002 - IPC

FIELD: railway transport. SUBSTANCE: invention is designed for mechanization of discharge of loose loads from open-top cars. Proposed vibrator has carrying frame with support platforms connected by cross beam with weights concentrated at ends and provided with strikers by means of flexible elements to form double weight system. Single-shaft vibration exciters are fixed on support platform. Axes of unbalance shafts of exciters are arranged in parallel with and symmetrically relative to axis of beam. Platforms are provided with anvils whose centers of masses are located on axes. Axis of anvils coincides with line of action of driving force P(t) = 2Posinωt. (Po is amplitude of driving force). Vibrator has hanger 9 for suspending vibrator from crane hook. EFFECT: reduced energy consumption in process of unloading, reduced service expenses. 2 dwg
