Description
Technical field
The utility model is related to a kind of hydraulic means, and in particular to be applied to the landing leg hydraulic cylinder of underground drill rig.
Background technology
Rig, one kind is widely used in mine locating, railway, highway, bridge, water conservancy and hydropower, tunnel, well, anchor pole, engineering geology
The heavy mechanical equipment of the drilling operation of exploration, ground source heat drilling, coal bed gas probing, rigs against outburst etc..Excavator, also known as excavation
Machinery, is that a kind of scraper bowl excavation is higher or lower than the material for holding machine side, and load haulage vehicle or unload to the earthwork of rickyard
Machinery.In above-mentioned engineering machinery, the landing leg hydraulic cylinder of stable performance safety is to ensure that the machineries such as rig, excavator carry out stabilization
The basic building of operation.The quality of landing leg hydraulic cylinder directly affects the normal work of whole machine.If landing leg hydraulic cylinder breaks down,
When can not carry out normal supporting role, it is necessary to leg hydraulic cylinder overhaul.Because the dismounting of hydraulic cylinder is more difficult, often
Rule repair method is first to be checked from the outward appearance of landing leg hydraulic cylinder, sees the situation for whetheing there is oil leak, if not having oil leak situation, then
The order write down from easy to difficult considers, analysis landing leg hydraulic cylinder failure that may be present.Hydraulic lock is changed first, is then looked at
Former failture evacuation is no after changing hydraulic lock.It is probably hydraulic cylinder itself in analysis reason if the failure of landing leg hydraulic cylinder is still suffered from
Failure, that is, need to open and inspect landing leg hydraulic cylinder.When generally proceeding to this step, it is found that cylinder body there occurs that evagination becomes
Shape, while the piston packing on piston is damaged, it is impossible to which cylinder body is divided into two independent sealed chambers.Work as piston packing
When not being damaged, effective work area that hydraulic cylinder bears external applied load is piston cross-section area A1, when piston packing is damaged
Afterwards, the whole chamber of hydraulic cylinder is connected, and hydraulic cylinder bears effective work area of external applied load by original piston cross-section area
A1It is changed into rod areas A2.In the presence of same external applied load F, the closing of hydraulic lock causes the pressure in landing leg hydraulic cylinder
Sharply increase, P when not being damaged by piston packing1=F/A1, it is changed into the P after piston packing is damaged2=F/A2, by
This understands F=P1A1=P2A2, i.e. P2=P1(A1/A2), the conventional structure design according to hydraulic cylinder understands, P2=2~5P1.It can be seen that
After the sealing property failure of piston seal, during hydraulic cylinder supporting identical load, the operating pressure in hydraulic cylinder will increase several times, from
And deform hydraulic cylinder body inwall footpath convex.When the deformation of hydraulic cylinder body is when elastic deformation is changed into plastic deformation, meeting
There is the phenomenon that supporting leg shrinks under external and effect, be unfavorable for being smoothed out for engineer operation, or even also affect operation
The life security of field worker.Therefore the sealing property failure of piston packing is found early, can avoid damaging hydraulic pressure in time
Cylinder cylinder body, beneficial to being smoothed out for engineer operation, protects workman's life security.
