Abstract
The invention relates to the field of hydraulic oil cylinder systems driven by multiple cylinders, in particular to a hydraulic oil cylinder system with multiple oil cylinders ascending and descending synchronously for an automobile shear type lifter and a two-column automobile lifter.
Description
Affiliated technical field
This patent relates to a kind of mode of operation of lifting machine hydraulic actuating cylinder.
Background technology
Automobile is to certain height by vehicle lifting with the effect of lifting machine, uphill process is that Hydraulic Pump is by under electric motor driven effect, drive the reciprocating motion of the pistons of hydraulic oil in oil pipe promotes hydraulic actuating cylinder, the mechanical energy of Hydraulic Pump is changed into the potential energy that in hydraulic actuating cylinder, piston promotes.
Summary of the invention
Because auto hoist requires after vehicle lifting, in the middle of vehicle, to leave certain space for automotive servicing operation, therefore auto hoist often requires two of left and right platform or bracket separated often on physical construction, by two covers or the above hydraulic ram of two covers, is acted on rising and the decline of lifting machine simultaneously.But because the left and right of the load on lifting machine after vehicle support is uneven, the hydraulic cylinder force that causes two platforms or bracket to use is uneven, synchronous and the level that can affect two platforms or bracket, therefore, auto hoist must guarantee horizontal accuracy the right and left synchronization lifting of two platforms or bracket.
Accompanying drawing explanation
Fig. 1 is the mode of operation of this patent hydraulic actuating cylinder.
In figure 1, master cylinder, 2 auxiliary oil cylinders, 3, fuel path switch 3,4, fuel path switch 4,5, check valve, 6, by pass valve, 7, electromagnetic valve, 8, flow regulating valve, 9, oil pump, 10, motor, 11, strainer valve, 12, oil groove.
Z1: total oil circuit, Z2: master cylinder oil inlet, Z3: secondary cylinder oil inlet, Z4: master cylinder oil outlet
A1: strong sectional area under master cylinder, A2: auxiliary oil cylinder cavity of resorption sectional area, A3: master cylinder epicoele sectional area.
The specific embodiment
For making auto hoist synchronization lifting, this patent is achieved through the following technical solutions (see figure 1): hydraulic circuit is comprised of main hydraulic ram cylinder component, secondary hydraulic piston cylinder assembly, hydraulic pressure auxiliary member, control cock, Hydraulic Pump etc.
This patent hydraulic circuit principle and specific descriptions are as follows:
Before work, open fuel path switch 4, hydraulic oil is entered to auxiliary oil cylinder cavity of resorption from Z1 through 4 to Z3 under the driving of Hydraulic Pump, through Z4, enter master cylinder epicoele simultaneously, fill with hydraulic oil.
During work, close fuel path switch 4, open fuel path switch 3, hydraulic oil is entered to master cylinder cavity of resorption from Z1 through 3 to Z2 under the driving of Hydraulic Pump.
Master cylinder is different with pair oil cylinder cylinder diameter.Allow master cylinder cavity of resorption sectional area A1=auxiliary oil cylinder cavity of resorption sectional area A2+ main oil cylinder piston rod area A4, that is: make the sectional area A2 of the sectional area A3=auxiliary oil cylinder cavity of resorption hydraulic oil of master cylinder epicoele hydraulic oil.
When oil pump promotes master cylinder and upwards moves, main oil cylinder piston upward movement also promotes auxiliary oil cylinder piston while upward movement with the hydraulic oil pass through in its epicoele of capacity, to reach the synchronous upward movement of major-minor oil cylinder; Equally, during lifting machine decline work, secondary cylinder piston promotes master cylinder piston downwards and oppositely and synchronously moves downward.
This programme be major and minor oil cylinder respectively and left and right lifting vehicle, by master cylinder and auxiliary oil cylinder, formed the connection mode of series connection, and strictly control the diameter of main oil cylinder piston bar, make the synchronously motion up or down of two oil cylinders, to reach lifting machine the right and left synchronization lifting vehicle.
Claims (1)
1. adopt major and minor oil cylinder to be connected in series with oil pipe, when master cylinder is subject to hydraulic-driven operation, master cylinder epicoele hydraulic oil promotes secondary cylinder piston by oil pipe to secondary cylinder cavity of resorption, takes master cylinder epicoele identical with the hydraulic oil sectional area of secondary cylinder cavity of resorption, makes master cylinder and secondary cylinder synchronized operation.
