Description
Technical field
The utility model relates to engineering jacking equipment field, particularly relates to a kind of hydraulic jack efficiently.
Background technology
Hydraulic jack is a kind of weight-lifting equipment by hydraulic oil, the rigid top of jack inside being lifted part plunger upward movement jack-up weight.Operationally, hydraulic oil enters jack body along hydraulic port to existing hydraulic jack, by hydraulic cavities progressively mineralization pressure by piston jack-up, make piston upwards carry out jacking campaign, weight jack-up the most at last.
According to prior art: the propulsive effort of hydraulic jack is provided by hydraulic efficiency pressure system, when hydraulic efficiency pressure system is run, by hydraulic oil, in hydraulic cavities, progressively mineralization pressure is by piston jack-up, and the kinematic velocity making piston slowly, reduces the work efficiency of jack.
According to prior art: there will be the phenomenon that the situations such as internal cavity damages, internal part installation is not in place cause leakage of oil when hydraulic jack withstands on operation, cause that jack speed is uneven, thrust is not enough, make the jacking speed of piston undesirable, affect the normal operation of equipment; After hydraulic jack has withstood on jacking work, must ensure constant oil pressure, maintaining the support to weight, is very large test to hydraulic efficiency pressure system, and hydraulic jack need keep higher oil pressure to ensure the continued support of jack pair weight for a long time, there is certain danger.
According to prior art: hydraulic jack operationally there will be internal part generation mechanical vibration and piston and die cavity inwall and the noise that situation produces such as occurs to rub, and causes noise pollution to surrounding environment.
Summary of the invention
According to above technical matters, the utility model provides, a kind of hydraulic jack efficiently, comprises jack body, hydraulic port, piston, die cavity, hydraulic cavities, is characterized in that: also comprise base plate, air cylinder, pressure liftable post, gas pressure regulator, adapter plate, airflow line, sound isolating layer, atmospheric pressure cavity, described gas pressure regulator is arranged on the bottom of jack body by adapter plate, described jack body lower end is provided with base plate, described base plate interior is provided with airflow line, described airflow line one end is admission port, the other end is air extractor duct, described gas pressure regulator is connected with airflow line by admission port, described jack body interior is provided with piston, jack body is divided into the die cavity on top and the hydraulic cavities of bottom by described piston, described base plate upper end is provided with air cylinder, and described air cylinder inside is provided with pressure liftable post, and the upper end of described pressure liftable post is connected with piston, atmospheric pressure cavity is formed bottom the lower end of described pressure liftable post and air cylinder, described atmospheric pressure cavity is communicated with airflow line by air extractor duct, described hydraulic port and hydraulic chamber into communication, is provided with sound isolating layer inside described jack body.
The beneficial effects of the utility model are: the utility model has set up actuating device of atmospheric pressure on existing hydraulically powered basis, gas pressure regulator carries out dipping and heaving by controlling gas intensity to pressure liftable post, make hydraulic oil and pressure liftable post act on piston simultaneously and carry out dipping and heaving, improve the speed that piston carries out dipping and heaving in jack, add the work efficiency of jack; The pressure liftable post that the utility model is set up, jack occur leakage of oil cause piston velocity uneven, push away hypodynamic situation time, can by the rising or falling speed of adjustable pressure lifting column, ensure the stationarity of piston lifting, avoid because of after hydraulic system failure, cause the operational failure of jack jacking weight, occur construction risk; The sound isolating layer that the utility model is set up, by being arranged on inside die cavity, making noise just carry out weakening process from sound source, decreasing the noise spread out of by device interior, avoid producing noise pollution to surrounding environment.
