Description
Technical field
The utility model relates to a kind of hydraulic jack, especially hydraulic synchronous oil cylinder.
Background technique
At present, because can not warranty element oil cylinder synchronous working while adopting four elevating rams, easily there is shipping container rollover in lifting process in inland container transport vehicle loading and unloading container, cause accident, the domestic air bag lifting shipping containers that adopt more.Adopt air bag lifting structure, the lifting time is long, inefficiency; Because tractor braking mechanism adopts gas control form, once the gas leakage of air bag lifting structure can cause brake system malfunctioning, lead to serious traffic accident.
Summary of the invention
In order to overcome the in-problem deficiency of prior art, the utility model provides a kind of novel hydraulic synchronous oil cylinder, this hydraulic synchronous oil cylinder, as the control oil cylinder of controlling four elevating ram synchronous liftings, decline, can guarantee that the synchronous degree of elevating ram is between 2/1000ths to 3/1000ths.
The utility model solves the technological scheme that its technical problem adopts: hydraulic synchronous oil cylinder, by stud, nut, spring washer, outer-hexagonal plug screw, seal washer, cylinder bottom, O RunddichtringO, piston in combination sealing, piston, cylinder barrel, guide sleeve, axle seal ring, hexagon socket cap head screw, O RunddichtringO back-up ring, card key, card key protecting jacket, piston rod, dust ring, cylinder cap, combination seal packing ring, fittings body, hydraulic fluid port protective hat, fittings body, hydraulic fluid port protective hat forms, there is piston rod at center, there is cylinder bottom one end of piston rod, cylinder bottom one side has fittings body, combination seal packing ring, O RunddichtringO, hydraulic fluid port protective hat, cylinder bottom has spring washer up and down, nut, stud.There is O RunddichtringO cylinder bottom outside.There is piston cylinder bottom the inside, and there is piston in combination sealing piston outside, and there is the O RunddichtringO with O RunddichtringO back-up ring piston the inside, and there are card key protecting jacket, card key in piston both sides, and there is hexagon socket cap head screw the outside of card key protecting jacket.The other end of piston rod is with the cylinder cap of dust ring, and there are spring washer, nut, stud in cylinder cap outside.In the middle of piston rod, be evenly equipped with 3 guide sleeves, piston, there is axle seal ring guide sleeve the inside.Cylinder bottom, guide sleeve, cylinder cap have the outer-hexagonal plug screw with seal washer above.There is cylinder barrel the outside of guide sleeve, piston.Before guide sleeve, cylinder cap, there is the fittings body with combination seal packing ring, O RunddichtringO, hydraulic fluid port protective hat.
This hydraulic synchronous oil cylinder, as the control oil cylinder of controlling four elevating ram synchronous liftings, decline, can guarantee that the sync rates of elevating ram is between 2/1000ths to 3/1000ths.
The piston primary seal of synchronous fuel tank adopts Parker KR type Combined seal ring of piston, has good pressure holding function.Synchronized cylinder oil-feed oil duct, on piston rod, so simplifies the structure and has reduced leakage hidden danger.
The piston of this hydraulic synchronous oil cylinder, guide sleeve, cylinder cap, cylinder bottom adopt ironcasting, and because ironcasting has the characteristic of selflubricating, hydraulic synchronous oil cylinder does not have piston guide ring and piston rod guide ring.
The beneficial effects of the utility model are that this hydraulic synchronous oil cylinder, compares with isometric synchronized cylinder and have advantages of that volume is little, lightweight, synchronization accuracy is high.
