Abstract
The utility model discloses a kind of hydraulic jack range controlling mechanism, it includes fuel tank, hydraulic pump, effusion meter, reversal valve and oil cylinder；The entrance of described hydraulic pump connects fuel tank by pipeline, exports and is followed by rodless cavity to oil cylinder through effusion meter and solenoid directional control valve by pipeline after first, and the rod chamber of oil cylinder is followed by oil sump tank by pipeline through solenoid directional control valve.Controlling electromagnetic reversing switch by effusion meter when this structure hydraulic oil cylinder stroke controlling organization works, when flow arrives setting value time, oil cylinder performs stagnation action, can realize Stroke Control, has convenient accurate, the feature of low cost of hydraulic jack stroke adjustment.
Description
Technical field
This utility model relates to hydraulic jack, is specifically related to a kind of using oil cylinder as hydraulic jack stroke during executive component
Controlling organization.
Background technology
Hydraulic jack is, in hydraulic means, hydraulic energy is converted to mechanical energy, it is achieved the executive component of straight reciprocating motion,
Hydraulicdriven advantage is that stable movement, bearing capacity greatly, easily realize stepless time adjustment, are easily achieved overload protection.Existing
The structure that the commonly used mechanical type of hydraulic jack range controlling mechanism is spacing and travel control switch controls, there is Stroke Control
Adjusting defect the most convenient, coarse, make hydraulic jack stroke arbitrarily not adjust, this just constrains hydraulic system in intellectuality
Use on field.And the high-precision hydraulic servo system of costliness, not only executive component must use servo-cylinder, for ensureing essence
Degree needs various sensors to carry out signals collecting and amplification, and System self-test is, and then control motor and carry out differing from benefit and form one
Closed loop, its structure is extremely complex, and cost is high.
Summary of the invention
The purpose of this utility model is to provide convenient accurate, the hydraulic jack stroke control of low cost of a kind of oil cylinder stroke regulation
Mechanism processed.
For realizing object above, this utility model one hydraulic jack range controlling mechanism includes fuel tank, hydraulic pump, flow
Meter, reversal valve and oil cylinder；The entrance of described hydraulic pump connects fuel tank by pipeline, export by pipeline first after through effusion meter and electricity
Magnetic reversal valve is followed by the rodless cavity to oil cylinder, and the rod chamber of oil cylinder is followed by oil sump tank by pipeline through solenoid directional control valve.
Electromagnetic reversing switch is controlled by effusion meter during the work of this utility model one hydraulic jack range controlling mechanism, when
Time flow arrives setting value, oil cylinder performs stagnation action, can realize Stroke Control.
The hydraulic jack range controlling mechanism of said structure uses and utilizes effusion meter and solenoid directional control valve to adjust oil easily
Cylinder stroke, more convenient compared with mechanical operation, it is more accurate that relatively travel switch adjusts mode, and relatively electrohydraudic servomechanism has carried out very great Cheng
The simplification of degree, although degree of accuracy can not be compared with it, but can simply reach the effect of electrichydraulic control oil cylinder stroke, Ke Yiying
For the various intelligent hydraulic drive design that required precision is the harshest.
Accompanying drawing explanation
Fig. 1 is this utility model one hydraulic jack range controlling mechanism structural representation.
Reference: fuel tank 1, hydraulic pump 2, effusion meter 3, reversal valve 4, oil cylinder 5, rod chamber 6, rodless cavity 7.
Detailed description of the invention
With detailed description of the invention, this utility model one hydraulic jack range controlling mechanism is made into one below in conjunction with the accompanying drawings
Step describes in detail.
The hydraulic jack range controlling mechanism of this utility model one shown in Fig. 1 includes fuel tank 1, hydraulic pump 2, effusion meter 3, changes
To valve 4 and oil cylinder 5；The entrance of described hydraulic pump 2 connects fuel tank 1 by pipeline, export by pipeline first after through effusion meter 3 and electricity
Magnetic reversal valve 4 is followed by the rodless cavity 7 to oil cylinder 5, and the rod chamber 6 of oil cylinder 5 is followed by oil sump tank 1 by pipeline through solenoid directional control valve 4.
Electromagnetic reversing switch is controlled by effusion meter during the work of this utility model one hydraulic jack range controlling mechanism, when
Time flow arrives setting value, oil cylinder performs stagnation action, can realize Stroke Control.Its operation principle see Fig. 1: hydraulic oil from
Fuel tank 1 flows out and pressurizes through hydraulic pump 2, and through effusion meter 3, this effusion meter can set flow value, then orders when arriving flow value
Make solenoid directional control valve 4 action, thus control the stroke of oil cylinder 5.
Concrete operations: when reversal valve is leftward position shown in Fig. 1, for oil cylinder rodless cavity oil-feed, now oil cylinder is for stretching out
Action；When flow arrives setting value, reversal valve action is to position in shown in Fig. 1, then oil cylinder is stagnated, now the stretching of cylinder piston rod
Go out distance and be the stroke after oil cylinder adjusts；When manually reversal valve being pushed into right positions shown in Fig. 1, rod chamber oil-feed, nothing
The oil return of bar chamber, oil cylinder is retracted.After hand-reset, i.e. recirculate, thus realize utilizing effusion meter to control oil cylinder stroke.
Claims (1)
