HYDRAULIC JACK LIFTING POWER BOOSTER

FIELD: mechanics; hydraulics. ^ SUBSTANCE: said invention relates to control over three-dimensional position of a construction, as well as to control over stress condition thereof. Hydraulic jack lifting power reciprocating booster comprises a through flared nozzle filled with plastic actuating medium, a distributing plate made of malleable iron and reinforced with periodic-profile steel rods with a steel ring connected thereto and encircling the steel nozzle outlet with taper of 2-a = 100...80. The nozzle is connected, by means of three poles, to the top support plate, to which the hydraulic jack plunger is suspended, and is mounted onto slidable distributing plate. Hydraulic jack flange is supported by plastic actuating medium in the upper nozzle opening and is connected, by means of oil piping, to pumping unit operating in static or surging mode, as well as to control console. ^ EFFECT: higher lifting power and extended plunger stroke of hydraulic jack. ^ 1 dwg
