VIBRATORY PILE DRIVER Russian patent published in 2020 - IPC E02D7/18 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, particularly, to working elements for immersion of pile elements in various types of soils. Vibratory pile driver consists of hydraulic motor and two shafts rotating in opposite sides by means of gear wheels. Hydraulic motor is installed in the housing and drives it in reciprocal motion through the belt drive and unbalance pairs on the shafts. Body itself, on which a head piece for fixation of pile elements is installed in lower part, is fixed with the help of pads in U-shaped frame of vibratory pile driver. Hydraulic motor is connected with hydraulic line of transport-process machine through controlled throttle, providing differentiated supply of operating liquid depending on controller control signal, converting information transmitted simultaneously from the range finder and tachometer arranged on the vibratory pile driver frame.

EFFECT: technical result consists in improvement of quality of immersion of pile elements in different types of soil, enabling control of operation of hydraulic motor.
