Description
Technical field
The present invention relates to assist field, and in particular to high-effect hydraulic jack.
Background technology
At present, the lifting implement of onboard, there is spiral and two kinds of jack of fluid pressure type, be it is manually operated, it is time-consuming
Arduously, working condition is poor and security is low.With small and medium-sized cars such as cars, progressively Jin Ren families, traditional hand jack are got over
To be more out of favour, and it can not be moved rapidly in unloaded stage, pressure bearing head, operating efficiency is low, and labor intensity is big.
The content of the invention
In order to solve the above problems, the present invention provides one kind and can quickly moved in the unloaded stage, saves the time, improves work
Make efficiency, and bearing capacity is big, safe and reliable high-effect hydraulic jack.
High-effect hydraulic jack of the present invention, including big cylinder plug and pumping cylinder, the big cylinder plug are arranged in vat cylinder barrel,
The bottom of the vat cylinder barrel is connected by stop valve with fuel tank, and a small cylinder plug is provided with the big cylinder plug, described big
Cylinder plug inner chamber is connected by the first check valve with fuel tank, while is connected by pressing oil check valve with pumping cylinder, is set in the pumping cylinder
A piston is equipped with, the piston is connected by connecting rod with depression bar, and pumping cylinder is connected by oil sucting one-way valve with fuel tank.
Preferably, the cross-sectional area of vat plunger cavity and small cylinder plug is equal.
Preferably, small cylinder plug is connected by the second check valve with the inner chamber of big cylinder plug.
The present invention can be moved quickly in the unloaded stage, save the time, improve operating efficiency, and bearing capacity is big, safely may be used
Lean on.
Brief description of the drawings
Fig. 1 is the structural representation of high-effect hydraulic jack.
Reference：1- fuel tanks, 2- stop valves, the check valves of 3- first, the check valves of 4- second, 5- vat cylinder barrels, 6- vats
Plunger, the small cylinder plugs of 7-, 8- depression bars, 9- pistons, 10- pumping cylinders, 11- force feed check valves, 12- oil sucting one-way valves, 13- first work
Oil pocket, the working oil chambers of 14- second.
Embodiment
High-effect hydraulic jack of the present invention, including big cylinder plug 6 and pumping cylinder 10, the big cylinder plug 6 are arranged at vat cylinder
In cylinder 5, the bottom of the vat cylinder barrel 5 is connected by stop valve 2 with fuel tank 1, and a small cylinder post is provided with the big cylinder plug 6
Plug 7, the big inner chamber of cylinder plug 6 is connected by the first check valve 3 with fuel tank 1, while by pressing oil check valve 11 and pumping cylinder 10
It is connected, a piston 9 is provided with the pumping cylinder 10, the piston 9 is connected by connecting rod with depression bar 8, and pumping cylinder 10 passes through oil suction
Check valve 12 is connected with fuel tank 1.The cross-sectional area of the big inner chamber of cylinder plug 6 and small cylinder plug 7 is equal.Small cylinder plug 7 passes through second
Check valve 4 is connected with the inner chamber of big cylinder plug 6.
The cross-sectional area of the big inner chamber of cylinder plug 6 and small cylinder plug 7 is equal, therefore big cylinder plug 6 is made quickly in idle stroke section
Rise.And at the same time, the bottom of big cylinder plug 6 and the swept volume of the second working oil chamber 14 expand, and form vacuum, in air
In the presence of pressure, liquid is pushed the first check valve 3 open and flowed into plunger case 7 in fuel tank 1.And when the top contact of big cylinder plug 6 arrives
After load, the first working oil chamber intracavitary oil liquid pressure rises, and liquid pushes the second check valve 4 open, divides two-way while enter the first work
Make in oil pocket and vat cylinder barrel 5, check valve 1l is closed by pressure oil.When needing plunger to stop, stopping depression bar motion, vat cylinder barrel
Fluid in 5 closes force feed check valve 11, and big cylinder plug 6 is motionless with regard to self-locking.When needing the big cylinder plug 6 to return downwards, open
Stop valve 2, under gravity, the fluid in vat cylinder barrel 5 directly flow back to fuel tank 1, and the oil in the chamber of the first working oil chamber 13
Liquid flows back to fuel tank after pushing the second check valve 4 open, and now big cylinder plug 6 resets.
