Вібраційна трамбівка

Abstract

A vibratory rammer comprises a support plate with cavity former, with rod vibration guide placed inside, the support plate is fixed on casing by means of guides with stoppers. The device comprises inertial mass with a rod vibration guide in the lower part, this is spring-supported with a power spring and is connected through the inner cavity to the upper section of the movable inertial mass with respect to the upper traverse that by means of guides and the spring is fixed to the support plate with cavity former. The movable inertial mass comprises power rams, inner working cavities are hydraulically connected to the drive hydro-system to which a pulse control valve is connected, this is adjusted for periodical opening-closing of connection of the pressure hydro-line of the hydro-system. The mass is intended for supply of working liquid and its connection to sink.
