Description
Technical field
The present invention relates to hydraulic means field, especially a kind of stage lift hydraulic station.
Background technology
Hoist cylinder is a kind of conventional machinery device, and extremely wide is applied among a variety of plant equipment.In some liters
Hoist cylinder is also a kind of conventional lowering or hoisting gear in falling unit, such as stage field.
In the practical application of lowering or hoisting gear, hoist cylinder is vertically arranged more, in actual use, especially by stopping
Only state is to due to carrying the weight of object and the effect of piston deadweight, cavity of resorption can discharge largely suddenly during descending motion
Pressure, the release suddenly of so substantial amounts of pressure can not only cause piston decline during vibration, be also possible to cause when serious
The pipe breakage being connected with hoist cylinder, so as to cause hurtling down for piston, its object stall carried is dropped, cause
Serious accident.
In addition, its structure of existing hoist cylinder is usually that its epicoele and cavity of resorption are connected with main line respectively, and in phase
The corresponding switch valve of installation in pipeline is answered, so as to which whether hydraulic oil turns on the epicoele and cavity of resorption of hoist cylinder in control piper,
So as to control the state of hoist cylinder.
But said structure is in actual use, the problem of certain be present, because main line and hoist cylinder are direct
Connection, and be only controlled by single switch valve, therefore, when switch valve needs to conserve or produce other emergent problems,
Then often it is difficult to operate, it is necessary to which hoist cylinder is shut down, disassembling pipe is handled afterwards, such mode of operation not only difficulty
Greatly, there is also certain danger.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide effective lockup piston, hoist cylinder is effectively controlled
Pressure, it is steady to decline, lift a kind of stage lift hydraulic station of hoist cylinder security.
The present invention is achieved by the following technical solutions：
A kind of stage lift hydraulic station, including level control unit, cooling unit, heating unit, filter element, power
Unit, oil module, detection unit, safe unit and hoist cylinder, the power unit connects with oil module integrally to be made
For exporting the main line of hydraulic oil, it is characterised in that：Controlled in the main line with a hoist cylinder control unit and an auxiliary
The other end of one end turned in parallel of unit processed, the hoist cylinder control unit and Auxiliary Control Element integrally makes a branch pipe
Road, the bye-pass and an oil pressure supplement sustained release unit and are connected, the epicoele of oil pressure sustained release unit and the hoist cylinder and
Cavity of resorption is respectively turned on.
Moreover, the hoist cylinder control unit includes a proportioning valve, one end and the main line of the proportioning valve are in series,
The other end of the proportioning valve is connected with Auxiliary Control Element.
Moreover, the Auxiliary Control Element includes an electromagnetic change-over valve, one end and the main line phase of the electromagnetic change-over valve
Series connection, the other end and proportioning valve of the electromagnetic change-over valve are connected with the bye-pass.
Moreover, overflow valve, choke valve and hydraulic control are installed in the oil circuit that the electromagnetic change-over valve is connected with bye-pass
Check valve.
Moreover, the oil pressure sustained release unit includes balanced valve, pressure relieving valve, Fill valve and the second overflow valve, the lifting oil
With a pipeline connection, the balanced valve has been installed in parallel between two pipeline respectively for the epicoele and cavity of resorption of cylinder.
Moreover, by being connected with the pressure relieving valve in the pipeline that the cavity of resorption with the hoist cylinder connects, with it is described
The Fill valve is connected with the pipeline of the epicoele connection of hoist cylinder, the pressure relieving valve is connected with Fill valve by corresponding branch pipe
There is an external fuel tank.
Moreover, an overflow valve is installed between the pipeline that the cavity of resorption is connected and the pipeline for being provided with pressure relieving valve.
Moreover, the pressure relieving valve and Fill valve are magnetic valve.
The advantages and positive effects of the present invention are：
1st, in this hydraulic station, level control unit, cooling unit, heating unit, filter element, power unit, fuel tank list
Member, detection unit, safe unit and hoist cylinder, a complete hydraulic station system is formed, controlled afterwards by hoist cylinder single
Member and Auxiliary Control Element are controlled to the working condition of hoist cylinder.
2nd, in this hydraulic station, the structure of adoption rate valve and electromagnetic change-over valve parallel connection substitutes original switch valve and hoist cylinder
The structure of series connection so that hoist cylinder does not connect directly with main line, but is turned on respectively through proportioning valve or electromagnetic change-over valve,
In course of normal operation, hydraulic oil imports proportioning valve by main line, then enters through proportioning valve in hoist cylinder, and operating personnel can lead to
Cross proportioning valve to be controlled hoist cylinder, but when problem or failure occur for proportioning valve, then can pass through electromagnetism connected in parallel
Switching valve turns on hoist cylinder, during comparative example valve is repaired or conserved again afterwards, does not then interfere with hoist cylinder
Work, without to main line carry out disassembling section, greatly improve convenience and security.
3rd, in this hydraulic station, overflow valve, the setting of choke valve and hydraulic control one-way valve is then used to slow down hoist cylinder in start and stop
During impact caused by inertia so that hoist cylinder operates steadily.
4th, in this hydraulic station, when rupture, which occurs, for pipeline causes piston to be dropped under Gravitative Loads, because balanced valve is with rising
The pipeline of drop oil cylinder is in parallel, therefore balanced valve can effectively lift and carry out locking to oil cylinder, when its load excessive, can also pass through
Control balanced valve is slowly opened, and prevents system pressure from infinitely raising caused safety problem.
5th, in this hydraulic station, the cavity of resorption of hoist cylinder is connected with external fuel tank by pressure relieving valve, when the piston of hoist cylinder
During whereabouts, due to the limitation of pressure relieving valve, the hydraulic oil discharged by cavity of resorption can only be discharged slowly, therefore can prevent lower intracavitary
Hydraulic oil largely quickly discharge, so as to effectively play the effect that the hydraulic oil of lower intracavitary slowly discharges, under preventing that piston is quick
Shake caused by falling, epicoele connect external fuel tank, epicoele vacuum caused by piston falling speed can be prevented too fast by Fill valve
The problem of, further improve the stability and security of device.
6th, in this hydraulic station, the second overflow valve is connected with pressure relieving valve plays level pressure overflow effect, is further ensured that device
The safety of operation and stably；Pressure relieving valve and Fill valve are easy to control using magnetic valve.
