Description
Technical field
The present invention relates to mining machinery manufacturing technology field, especially a kind of hydraulic pressure cutting type percussive drill for exploitated ore.
Background technology
The existing medium size installations for carrying out grooved bit eye on stone and concrete is mostly pneumatic and electronic two kinds;
Pneumatic drilling machine mostly is rotary impact type, and the use of pneumatic drilling machine needs supporting air compressor machine, and the motor power (output) of air compressor machine is generally 18.5KW ~ 22KW, also needs incidentally multiple accessory equipment simultaneously; Equipment cost height power drain is large.
Electronic rig mostly is rotary-cutting type without percussion, and efficiency is low.During as drill diameter 60mm hole, every drilling depth rice needs more than ten minute; It is high that this just causes cost, and effect is low.
So, the percussive drill not only complex structure of prior art, bulky, and or only possess rotary impact and do not possess cutting function, or only possessing cutting function and without impact function, function is more single, range of application is subject to larger restriction.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of hydraulic pressure and cuts percussive drill, and this cutting-impact rig can solve pneumatic percussion drill pick complex structure, bulky, does not possess cutting function, the problem that range of application is restricted.
In order to solve the problem, the technical solution used in the present invention is: this hydraulic pressure cutting type percussive drill, comprise housing, cage and middle cage before being connected with described housing two ends, impact main spindle is provided with in described housing, described impact main spindle one end is connected with the oil motor be fixed on described middle cage by adapter sleeve, the other end stretches out described front cage and is connected with drill rod connector, in described housing, described middle cage place is provided with spring base, adjacent described front cage is provided with spiral surface jacking block, the spiral surface slide block of band concave station is provided with between described spring base and described spiral surface jacking block, described spiral surface slide block is connected with described housing by the first feather key, the impact spring be sleeved on described impact main spindle is provided with between the concave station of described spiral surface slide block and described spring base, the freewheel clutch comprising clutch spring and clutch roller and formed is set between described helical jacking block and described impact main spindle.
Above-mentioned hydraulic pressure cuts in percussive drill technical scheme, and technical scheme can also be more specifically: be provided with the drill rod connector fixed cover with cooling water channel between described front cage and described drill rod connector; Sealing ring is provided with between described drill rod connector and described impact main spindle and between described impact main spindle and described front cage; Circlip for hole is provided with between impact main spindle and described spiral surface jacking block described in described clutch place.
Further: described oil motor is connected with described impact main spindle through the described adapter sleeve inserted in bearing, described impact main spindle is connected with described adapter sleeve by the second feather key.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, the present invention can make drill bit at work while the rotary cutting of limit also with low-frequency impact, the two kinds of mode of operations that there is cutting-impact He only have cutting can be selected at work as required, cutting-impact pattern is mainly used in the drilling of hard brittle rock, and cutting mode is mainly used in the drilling of crumbly rock and earth; Drill bit cutting edge to crisp admant material produce simultaneously cutting and percussion, make its quick separating, and taken away by the current be pressed into from drill bit, thus compare only have impact or only have the rig of cutting to have higher drilling efficiency and speed; In addition, because the present invention possesses impact and cutting function simultaneously, therefore range of application is wider, also can be used for the bore operation of various rock and earth.
2, the present invention adopts hydraulic transmission mode to provide power for rig, has the feature of compact conformation, small volume, is particularly suitable for the mining in narrow.Simultaneously from power, complete same operation only for the half of pneumatic drilling machine is to about 1/3rd, and compared with electronic rig, during same bore diameter 60mm hole, every meter need only three minutes, and drilling time is only 1/3 to five, and penetration rate greatly improves.
3, rig of the present invention makes drill bit also carry out low-frequency impact while the rotary cutting of limit at work, frequency of impact is low, and the amplitude of vibrations is little, therefore is particularly suitable for mechanical grip operation, help operation concerning artificial simultaneously, the labour intensity that workman helps can be reduced.
4, rig of the present invention sends into current by drill bit endoporus to cutting face, dust can be taken out of again while cooling drill bit; Both extended bit life, dust pollution working space can be prevented again to ensure that field operation workman's is healthy.
5, rig of the present invention uses drill bit to take core out of, for rock formation analysis by drill bit endoporus in operation process; Therefore rig of the present invention can be used for rock stratum drilling operation.
To have operating cost low in the present invention in sum, and operating speed is fast, and effect is high, volume is little, feature simple to operate, is one comparatively advanced in current domestic Medium and smaller mines rig.
