Description
Technical field
The invention belongs to drilling equipment technical fields, are related to a kind of drilling machine big column firm sliding rail oil cylinder, oil piping system
And pillar.
Background technique
Coal mine crawler type all-hydraulic tunnel drilling rig, when it carries out construction drill, it usually needs hydraulic cylinder comes up and down
Its crawler belt car body and host are consolidated, external force when drilling machine gravity and work is born.Since coal mine down-hole tunnel size is limited, in portion
Divide under mine, heading sizes height is within 2m.Currently, be on the second firm oil cylinder adjunction extension bar top to upper plate.
Due to two-stage hydraulic cylinder because its is compact-sized, stroke longer than single stage oil cylinder can be achieved in given installation space, from
And it is widely used in the case where installation space anxiety;At least one hydraulic fluid port in existing two-level oil cylinder's oil feeding line
On the piston rod, hydraulic fluid port setting is on the piston rod since piston is movement rod piece, it will the sebific duct movement for driving connection hydraulic fluid port is held
Easily sebific duct is allowed to be worn, even drag and pull oil leak, and sebific duct length increases very much, arrangement inconvenience.
In existing invention the second firm oil cylinder be usually on the piston rod face adjunction extension bar top to upper plate.Oil cylinder into
Oil outlet concentrates design generally by design external oil pipe, focuses on external oil clot and designs two hydraulic fluid ports;Secondary cylinder is wherein
One hydraulic fluid port is usually to design on the piston rod.It is with piston rod movement that hydraulic fluid port is caused in cylinder efficient.
Existing second firm oil cylinder stroke falls short of, and one can not reach top, need face adjunction extension bar on the piston rod,
Handling are inconvenient, not solid and reliable enough;Existing second firm oil cylinder port designs the invention on cylinder body, and cylinder barrel outer wall is set
Oil pipe is counted, sliding rail stroke is shorter when cylinder body cannot be integrally used as to sliding rail carrying work package or being used as sliding rail;It will
The oil cylinder of hydraulic fluid port design on the piston rod can be used as sliding rail carrying work package, but piston rod is movement parts, will drive hydraulic fluid port
Oil pipe take exercises, oil pipe will receive abrasion, drag and pull oil leak, and the length of oil pipe to reach piston rod stretching extreme position
Length, when piston rod is withdrawn completely, oil pipe pipeline arrangement is inconvenient.
