Description
Technical field
This utility model relates to a kind of hydraulic jack, particularly to a kind of development machine guide hydraulic oil cylinder.
Background technology
Hydraulic energy is changed into mechanical energy by hydraulic jack, do the hydraulic actuator of straight reciprocating motion, its simple in construction, reliable operation, when realizing moving back and forth with it, deceleration device can be removed from, and in have drive gap, stable movement, is therefore used widely in the hydraulic system of various machineries.Development machine is the machine for digging straight underground passage, in development machine work process, advancing hydraulic pressure oil cylinder thereon can bear lateral load, and in the case of high side carries, the piston rod of microcosmic upper cylinder is easily to lopsidedness, when causing piston rod to move back and forth, and the frictional force between guide cover is relatively big, shock loading is big, and long-time piston rod or guide cover can produce defect, ultimately resulting in the fracture of piston rod, service life is short.
Utility model content
The purpose of this utility model is that a kind of reasonable in design of offer, good sealing effect, service life length development machine guide hydraulic oil cylinder.
nullTo achieve these goals，The technical solution adopted in the utility model is such that development machine guide hydraulic oil cylinder of the present utility model，Including cylinder body、Piston and piston rod，Cylinder body two ends are respectively arranged with protecgulum and bonnet，Piston is fixed on piston rod one end，Piston is arranged in cylinder body，The piston rod other end passes bonnet，Circumferentially arranged on described outside piston side face have O-ring seals，Oil outlet it is provided with on piston，It is provided with guide pad on piston rod outer wall，Oil supplying hole it is provided with on piston rod，Oil supplying hole is arranged on outside cylinder body，Oil supply gallery it is provided with in piston rod，Oil supply gallery one end connects with oil supplying hole，The other end connects with oil outlet，Described inboard wall of cylinder block is provided with the gathering sill slided for guide pad，Oil-in it is provided with on outer wall of cylinder block，Oil circuit it is provided with in cylinder side wall，Oil guiding hole it is provided with on oil circuit，Oil guiding hole communicates with gathering sill，It is provided with sealing device on described bonnet，Sealing device and plunger rod contacts.
As preferably, being provided with annular groove described outside piston week, described O-ring seals is two, and two O-ring seals are arranged in annular groove by pad.
As preferably, described bonnet inwall is provided with cannelure, and described sealing device includes that T-shaped sealing ring, T-shaped sealing ring are fixed in cannelure by two briquettings.
Compared with prior art, the utility model has the advantage of: this utility model reasonable in design, at inboard wall of cylinder block, gathering sill is set, guide pad is set on piston rod, guide pad can slide in gathering sill, in order to resist the lateral load suffered by piston rod, cylinder body arranges the oil circuit of band oil guiding hole, Castor Oil piston rod, greatly extends the service life of hydraulic jack；O-ring seals and sealing device, good sealing effect it is respectively provided with on piston and bonnet.
Accompanying drawing explanation
