Description
Technical field
The present invention relates to coal mine machinery field, and in particular to a kind of airborne advance support hydraulic control system of development machine is improved
Structure.
Background technology
Under extension during crossheading, made during top plate is normal using " once cutting the row of two row's supporting two " double endless form
Industry, gib use the airborne advance support of development machine, and application type is bolting with wire mesh type, and the use of the equipment realizes machinery
Change supporting operation, reduce operation intensity, improve drivage efficiency, the safety of Anchor Care operating personnel has been obtained effective guarantee.
The development machine support system of Shandong Milky Way scientific ＆ technical corporation, details are shown in its company official website http://
Www.sdthkj.com/chanpinshijie/vuzssb/186.html, product description http://www.doc88.com/
P-5485991129388.html, mainly including upper frame, body frame, fold cylinder 31, lift cylinders 32, shoring 33, balanced valve, two
Triple valve, high-pressure oil pipe, flow divider-combiner, multiple directional control valve 34 etc. form, and system oil-way figure is shown in Fig. 1, and its principle is timberer
When making, by the hydraulic power unit fuel feeding of development machine, promote two position three-way valve make hydraulic oil by flow divider-combiner enter balanced valve and
Support cylinder, folding ram, hoist cylinder, open support upper frame and rise, promote hoist cylinder to raise body frame, pass through multichannel
Reversal valve enter three group oil cylinders coordinated manipulation make upper frame, body frame be adjusted to required for height, angle and reach required branch
Stop after support force.
At present the problem of is, the spoil that two position three-way valve is easily tumbled during development machine cutting operation in use
Smash, and each hydraulic package pipeline caliber specification species of the product is more, pipeline quantity is more, and component number of fitting parts is more, and cost is high.
The content of the invention
The invention provides a kind of airborne advance support hydraulic control system improved structure of development machine, and system architecture is stable,
It is less likely to be damaged.
A kind of airborne advance support hydraulic control system improved structure of development machine, including driving oil way system and advanced branch
Hydraulic system is protected, the advance support hydraulic system includes upper frame, body frame, folds cylinder, lift cylinders and shoring, the lift cylinders
Including left lift cylinders and right lift cylinders, in addition to high-pressure ball valve, Highpressure Tee and tetrad valve group, driving oil way system leads to successively
Cross high-pressure ball valve, Highpressure Tee and quadruple valve group and respectively enter folding cylinder, left lift cylinders, right lift cylinders and shoring, regulation top
The height of frame and body frame.
The advantage of the invention is that：Replaced by using high-pressure ball valve, Highpressure Tee and tetrad valve group in original structure
Two position three-way valve, flow divider-combiner and multiple directional control valve, one can prevent from damaging, secondly cost can be reduced, thirdly can be with
The stability of raising system.
Brief description of the drawings
Fig. 1 is the schematic diagram of the existing advance support oil piping system referred in background of invention；
Fig. 2 is the system oil-way schematic diagram in the embodiment of the present invention 1.
Embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
Part of the embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
With reference to accompanying drawing 1, a kind of airborne advance support hydraulic control system improved structure of development machine of the present invention, including development machine
Oil piping system 1 and advance support hydraulic system 2, the advance support hydraulic system 1 include upper frame (not shown), body frame
(not shown), folding cylinder 11, lift cylinders and shoring 12, the lift cylinders include left lift cylinders 13 and right lift cylinders 14,
Also include high-pressure ball valve 15, Highpressure Tee and tetrad valve group 16, driving oil way system passes sequentially through high-pressure ball valve 15, high pressure three
Logical and tetrad valve group 16, which respectively enters, folds cylinder 11, left lift cylinders 13, right lift cylinders 14 and shoring 15, so as to adjust upper frame and
The height of body frame.
In actual production, by the way that high-pressure ball valve, Highpressure Tee and tetrad valve group, improved hydraulic operation is replaced
System pipeline quantity is reduced and caliber is unified, and convenient with changing after conduit failure, a hydraulic package quantity subtracts after complete equipment transformation
It is few, it is convenient to fix；Device systems function-stable, factory-designed all kinds of technical parameter requirements can be reached, realized improved
Function is guaranteed both quality and quantity；Part core hydraulic package realize that oneself making transformation greatly saved that the complete equipment comes into operation into
This.
It should be noted that herein, such as first and second or the like relational terms are used merely to a reality
Body or operation make a distinction with another entity or operation, and not necessarily require or imply and deposited between these entities or operation
In any this actual relation or order.Moreover, term " comprising ", "comprising" or its any other variant are intended to
Nonexcludability includes, so that process, method, article or equipment including a series of elements not only will including those
Element, but also the other element including being not expressly set out, or it is this process, method, article or equipment also to include
Intrinsic key element.In the absence of more restrictions, the key element limited by sentence "including a ...", it is not excluded that
Other identical element also be present in process, method, article or equipment including the key element.
