Description
Technical field
The utility model relates to a kind of geological drilling rig chassis support leveling device used, particularly geological drilling rig chassis hydraulic leg installed.
Background technology
The chassis of geological drilling rig is generally all provided with at 4 angles that supporting leg supports and leveling, and when supporting leg stretches out, can adjust chassis and ground and form different angles, and by hydraulic pressure or mechanical mechanism locking.The conventional supporting leg of current geological drilling rig has hydraulic pressure and two types of machineries, and mechanical lag generally adopts screw mechanism, by the rotating screw mechanism of manually exerting oneself, not only consuming time but also require great effort when use; Hydraulic leg adopts hydraulic jack, by the stretching motion leveling support chassis of hydraulic cylinder piston, time saving and energy saving.Hydraulic leg adopts hydraulic lock to lock conventionally; but time one length still has hydraulic fluid leak unavoidably; cause chassis to move up and down; hydraulic cylinder piston is exposed to outside for a long time as supporting leg simultaneously; collide with unavoidably; sealing and the application life of hydraulic leg oil cylinder are affected, even if there is the protection of rubber telescopic also still safe not.For this reason, some producers are put in hydraulic jack and piston in one cubic steel pipe and protect, and bearing pin is housed and carries out mechanical interlocking, but lack micro-adjusting mechanism, and chassis lifting can only be adjusted by back cushion piece, adjust very inconveniently also to expend time in.
Utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of hydraulic locking cylinder reliable, adjusts the time saving and energy saving geological drilling rig chassis hydraulic leg of chassis lifting.
Problem described in the utility model realizes with following technical proposals:
A kind of geological drilling rig chassis hydraulic leg, it comprises hydraulic cylinder, the upper and lower cavity hydraulic fluid port of hydraulic cylinder is connected with hydraulic lock by oil pipe, special feature is, described hydraulic cylinder setting within the outer tube, boatswain chair is fixed at outer tube top, boatswain chair connecting fluid cylinder pressure top, the outer wall of outer tube is provided with chassis junction plate, is provided with inner tube in outer tube, and inner tube is connected with the piston rod of hydraulic cylinder, uniform row's pin shaft hole on inner tubal wall, the outer tube lower end thread bush that is spirally connected, thread bush is provided with radial direction through hole, and bearing pin is fixed inner tube and outer tube through radial direction through hole and pin shaft hole.
Above-mentioned geological drilling rig chassis hydraulic leg, described inner tube lower end connects ball hinged support.
Above-mentioned geological drilling rig chassis hydraulic leg, the affixed guide pipe in inwall bottom of described outer tube, guide pipe inwall and outer wall of inner tube are slidably matched.
Above-mentioned geological drilling rig chassis hydraulic leg, described chassis junction plate is provided with bolt hole.
Above-mentioned geological drilling rig chassis hydraulic leg, described boatswain chair and hydraulic cylinder upper end are hinged, described piston rod end and inner tube upper articulation.
The geological drilling rig chassis hydraulic leg that the utility model provides, hydraulic jack is loaded in a circular outer pipe, hydraulic jack top is connected with boatswain chair, bottom is connected with inner tube, inner tube bottom is connected with ball hinged support, uniform pin shaft hole in inner tube, the bottom of the outer tube thread bush that is spirally connected, is drilled with a radial direction through hole on thread bush.Reach the spot while needing leveling at rig, hydraulic cylinder piston rod stretches out, inner tube is also stretched out thereupon, the firm ground connection of ball hinged support, rotation thread bush, thread bush through hole is alignd with interior steel pipe through hole, insert bearing pin, inner tube and outer tube link into an integrated entity by bearing pin like this, and outer tube is fixed by chassis junction plate and chassis rigidity, cylinder piston rod also can not stretch again, reaches the object of mechanical interlocking; Hydraulic lock is housed on outer tube, and hydraulic lock is pinned oil cylinder piston and can not be retracted, and so just forms hydraulic machinery locking mechanism, can guarantee the long-time position stability in chassis, guarantees the normal work of rig.In the time of lifting rig whole, owing to being welded with boatswain chair above outer tube, can conveniently lift, and balance is also very good.The beneficial effects of the utility model are: adjust chassis time saving and energy saving; Locking mechanism guarantees the long-time held stationary in chassis; Convenient when lifting base plate; Simple with chassis connection; Micro-adjusting mechanism is easy to operate; Very reliable to oil cylinder piston protection.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1.
In figure, each list of reference numerals is: 1, boatswain chair, 2, outer tube, 3, hydraulic cylinder, 4, hydraulic lock, 5, piston rod, 6, chassis junction plate, 7, inner tube, 8, pin shaft hole, 9, guide pipe, 10, thread bush, 10-1, radial direction through hole, 11, bearing pin, 12, ball hinged support.
The specific embodiment
Referring to Fig. 1, Fig. 2, the utility model comprises hydraulic cylinder 3, outer tube 2, inner tube 7 and ball hinged support 12, and outer tube inner tube is all cylindrical shape, and within the outer tube, outer tube can play the function of protection piston rod in hydraulic cylinder setting.Boatswain chair 1 is welded on outer tube 2 tops, boatswain chair and hydraulic jack upper articulation, hydraulic lock 4 is fixed on the outer wall place of outer tube 2, be connected with the upper and lower cavity hydraulic fluid port of hydraulic jack by oil pipe, piston rod 5 ends and the inner tube 7 of hydraulic jack are hinged, uniform row's pin shaft hole 8 on inner tubal wall, the outer tube lower end thread bush 10 that is spirally connected, thread bush is provided with radial direction through hole 10-1, and bearing pin is fixed inner tube and outer tube through radial direction through hole 10-1 and pin shaft hole 8.Connect ball hinged support 12 in inner tube 7 lower ends.At the affixed guide pipe 9 in the inwall bottom of outer tube 2, guide pipe inwall and outer wall of inner tube are slidably matched, and the movement that guide pipe is inner tube provides guiding.The outer wall of outer tube is provided with the chassis junction plate 6 for connecting borer chassis, and chassis junction plate is provided with bolt hole, can make supporting leg be connected fast with chassis by bolt.
