A hollow piston of the hydraulic oil cylinder is arranged with an inner slide-way, two ends of the inner slide-way are fixedly connected with the piston, a hollow push rod is arranged in the inner slide-way, the hollow push rod and the piston wall are arranged with a plurality of oil holes, the push rod and the hydraulic oil cylinder barrel are fixed on the upper end cover, an oil inlet is arranged on the piston lower end, and an oil outlet is arranged on the cylinder barrel bottom part; the hydraulic anchor rod drilling machine has simple and beautiful outer part, light volume, small external damage probability, as well as long service life, which can realize height compensation with high stability, and can realize safe production.

Description

The fluid pressure type jumbolter

Technical field

The utility model relates to the rig of usefulness such as mine, building, especially relates to a kind of fluid pressure type jumbolter that is used for engineering support.

Background technology

Existing pneumatic type, fluid pressure type jumbolter, because it is its volume is little, in light weight and be widely used, but, these jumbolters, especially fluid pressure type jumbolter, in order to compensate adjustable height, enhanced stability has been set up such as ancillary facilities such as slideway, compensating cylinders in its outside, cause the jumbolter outside in disorder, not attractive in appearance, and the poor working environment of jumbolter itself, be easy to save bit by bit dust or reel, make the outside damage of rig, shorten its application life; In addition,, only rely on leading truck, can't make rig keep stability, thereby increased user's work difficulty because drilling cramp needs rotation at a high speed.

Summary of the invention

The purpose of this utility model is the defective that overcomes above-mentioned prior art, and a kind of specious, light, long service life, fluid pressure type jumbolter that stability is high are provided.

The technical solution of the utility model is:

A kind of fluid pressure type jumbolter, by hydraulic motor, hydraulic jack, base, drilling cramp, upper end cover and the handgrip of establishing thereon constitute, and are provided with inner slide in the hollow piston of hydraulic jack, all fixedly connected with piston in the two ends of described inner slide, hollow push rod is located in the inner slide, is equipped with several oilholes on itself and the piston wall, and the cylinder barrel of push rod and hydraulic jack all is fixed on the upper end cover, inlet nozzle is located at the lower end of piston, and oil outlet is located at the bottom of cylinder barrel;

The cross section of described inner slide, push rod and piston cross section special-shaped.

Fluid pressure type jumbolter of the present utility model, have the following advantages: the altimetric compensation function that 1) can realize rig: this structure is provided with inner slide in hollow piston, push rod is located in the inner slide, and be equipped with several oilholes on the piston wall, when hydraulic jumbolter is worked, hydraulic oil is through inlet nozzle, enter the cavity of piston, after the oilhole on the inner slide, hollow push rod flows into, along with the continuous increase of pressure, hollow push rod rises along inner slide, and hydraulic oil promotes to move on the upper end cover, and drive the drilling cramp rising, thereby realize altimetric compensation; 2) can strengthen the stability of rig: when this structure has overcome the drilling cramp height rotation of domestic and international jumbolter, only depend on leading truck two to cause rig can't keep good stability, this mechanism becomes abnormity with the cross section of that slideway, hollow push rod with the Cross section Design of piston, thereby make the rig can be because of the rotation of drilling cramp along with rotation, increased its stability, also avoid the decentraction phenomenon of jumbolter, also greatly reduced user's work difficulty simultaneously, realized safety in production; 3) can reach purpose dustproof, that increase the service life: this mechanism places slideway in the oil cylinder, push rod is fixedlyed connected with upper end cover with cylinder barrel, slideway and piston are fixed on the base, thereby make it outside succinct, and can reduce accumulating of dust, reduction is to the infringement probability of rig, thereby prolongs its application life; The processing simple in structure, easy of this fluid pressure type jumbolter, size are little.

Description of drawings

Fig. 1 is the structural representation of the utility model fluid pressure type jumbolter.

The specific embodiment

As shown in Figure 1, this fluid pressure type jumbolter, by hydraulic motor 1, hydraulic jack, base 2, drilling cramp 10, upper end cover 3 and the handgrip of establishing thereon 4 constitute, and hydraulic jack comprises cylinder barrel 9 and hollow piston 5, inner slide 7 is located in the hollow piston 5, its two ends all are fixed on the inwall of piston 5, the inner slide 7 and the cross section of establishing hollow push rod 6 within it all with piston 5 abnormity, rotate to prevent rig, increase its stability, the wall of push rod 6 and inner slide 7 is provided with several oilholes 8, and push rod 6 all is fixed on the upper end cover 3 with cylinder barrel 9, and this structure can realize the altimetric compensation function; Piston 5 is provided with fairlead 13, Yx RunddichtringO 14, O RunddichtringO 17, dust ring 15, Supporting ring 16 etc. with the contact surface of cylinder barrel 9, with play guiding, prevent dust, the purpose of supporting, leakproof; Inlet nozzle 12 is located at the lower end of piston 5, and oil outlet 11 is located at the lower end of cylinder barrel 9, and inlet nozzle 12 all is connected on the oil duct through reversal valve with oil outlet 11.

During jumbolter work, hydraulic oil through inlet nozzle 12, enters the cavity of piston 5 by oil duct, reversal valve, after the oilhole 8 on the inner slide 7, hollow push rod 6 flows into cavity A, along with the increase of pressure, hydraulic oil promotes to move on the upper end cover 3, drives on the fixedly connected with it cylinder barrel 9 and moves, thereby driving drilling cramp 10 raises, realize altimetric compensation, at this moment, push rod 6 rises along inner slide 7 with upper end cover 3, because its cross section is different with the cross section of piston 5, thereby increase stability; After jumbolter is finished once boring work, switch reversal valve, make hydraulic oil enter cavity B between cylinder barrel 9 and the piston 5, owing to the pressure effect by oil outlet 11, promote to move on the piston 5, cavity A internal pressure is increased, and the hydraulic oil in it is then entered in the hollow push rod 6 by oilhole 8, flows out through inner slide 7, oil outlet 11, along with cavity A internal pressure reduces, make upper end cover 3, hollow push rod 6 move down, move down, recover reset condition thereby drive drilling cramp 10.
