The hydro -cylinder install the free rotation hand (hold) outward, the pillar lag is installed outward to the hydro -cylinder, the hydro -cylinder bottom is provided with the base, is provided with air duct and reset spring in the cylinder of living. Three way valve surface be provided with twice annulars slot, the utility model discloses can be effectual prevent that the three way valve from can follow departure in the disk seat, cylinder from the splice fracture that prevents to live, it is all more convenient to make that liquid, tapping are annotated to the pillar, the pillar is retrieved.
Description
Technical field
The present invention relates to the outside injection type hydraulic pillar in mine support field, the hydraulic prop of a kind of top cover energy Universal rotary.
Background technology
At present, the outside injection type hydraulic pillar that underground coal mine uses, mainly it is made up of top cover, live cylinder, handle body, triple-use valve, valve seat, oil cylinder, piston, base, back-moving spring, sealing member, guide ring, connection steel wire etc..In using at the scene, there are the following problems: 1) uses in tunnel, and as top board tilts (this is the natural phenomena of ocurrence of coal seam), pillar can not vertical top base plate, can only vertically install, this results in four pawls of stud overcap, and two with strength, two the most with strength, causes pillar unstable, unfavorable to safety.2) valve seat of existing pillar is welded to live on post, and cylinder of living is three joint butt welding, and pillar, when more than 2.2m, often has cylinder alive to rupture from weld, causes hidden danger.3) triple-use valve can fly out from valve seat, causes casualty accident.4) at coal-face, in order to reach the straight requirement of pillar, workman's posts bottom that usually pounds with a hammer is looked for directly, causes and is deformed bottom oil cylinder, causes post alive can not be reduced to down the fault at the end.5) require now that triple-use valve is parallel with work surface, if triple-use valve installation site is bad, make setting prop fluid injection, prop drawing tapping inconvenient.
Summary of the invention
In order to overcome existing outside injection type hydraulic pillar top cover do not adapt to top board tilt problem, triple-use valve can fly out from valve seat hurt sb.'s feelings, live cylinder from problems such as weld fractures,
The present invention provides the hydraulic prop of a kind of top cover energy Universal rotary, to achieve these goals, the technical scheme is that Universal rotary top cover hydraulic prop, including cylinder of living, it is characterized in that: cylinder one end of living is provided with bulb coupling sleeve, Universal rotary ball is installed in bulb coupling sleeve, Universal rotary ball is provided with top cover or arch shaped trays, it is provided with oil cylinder below cylinder alive, outside cylinder alive, connection valve seat is installed, couple valve seat and triple-use valve is installed, triple-use valve surface configuration has ring-shaped groove, couple valve seat and be provided with anticreep knob, anticreep knob coordinates with the ring-shaped groove on triple-use valve surface.
It is provided with outside described oil cylinder and rotates freely hands handle, pillar protective jacket is installed outside oil cylinder, bottom oil cylinder, be provided with base, in cylinder of living, be provided with airway and back-moving spring.
Described triple-use valve surface configuration has twice ring-shaped groove.
The present invention can effectively prevent triple-use valve from can fly out from valve seat, prevents cylinder alive from rupturing from weld, makes pillar fluid injection, tapping, pillar reclaim the most convenient.
