Description
Technical field
The present invention relates to a kind of hidden hole drilling power head buffer units, are suitable for rock drilling machinery down-the-hole drill.
Background technology
Down-the-hole drill is widely used in the broken rock and soils such as mine, water power field, and power head is the key that down-the-hole drill portion
Part, performance and service life influence rock drilling drilling efficiency very big.Due to when hidden hole drilling works, what down-the-hole air hammer generated
Impact vibration acts through drilling rod and is transmitted on dynamic head main spindle, and the influence to parts such as power head internal bearings, gears is very
Greatly, so increasing a buffer unit between power head and impactor, impact of the impactor to power head can effectively be slowed down
Effect of vibration increases service efficiency and the service life of power head.
Invention content
The present invention solves the deficiencies in the prior art and a kind of can effectively mitigate impact of the down-the-hole air hammer to power head
Effect of vibration protects screw thread, improves the hidden hole drilling power head buffer unit of the service life of hidden hole drilling power head.
A kind of hidden hole drilling power head buffer unit, including splined shaft described in threaded connector, splined shaft and spline housing are installed
In spline housing, the splined shaft is mounted on by spline housing on threaded connector, the threaded connector and dynamic head main spindle
It connects, a circle groove, the threaded connector is machined on one end outside that the dynamic head main spindle is connect with threaded connector
Upper surface connect with dynamic head main spindle by flange, the flange is that at least two halves are assembled, and the upper end of the flange is set
After having the flange collar with the groove match, the flange to be connect with threaded connector, the flange collar is mounted in the groove.
The flange, threaded connector and spline housing are connected by bolt, the spring washer on bolt.
The flange, threaded connector and spline housing also pass through the elastic cylinder pin connection between adjacent bolt.
The threaded connector is threadedly coupled to by API on dynamic head main spindle.
Further include that the first cushion pad, the second cushion pad, sleeve, piston rod seals, the first O-ring seal and second are O-shaped
Sealing ring, part of the splined shaft in spline housing are equipped with the first buffering between threaded connector in the movement direction
The second cushion pad is installed between pad and spline housing, it is O-shaped to be equipped with first between the spline housing and threaded connector joint face
Sealing ring seals, and the sealing of the second O-ring seal, the screw thread are equipped on the threaded connector and dynamic head main spindle joint face
The middle part of connector and splined shaft is equipped with stomata, and the stomata of the threaded connector and splined shaft passes through sleeve connection, the set
Cylinder connects with piston rod seals sealing, the splined shaft is equipped on threaded connector and splined shaft joint face with spline housing outlet
Dustband is installed, the spline housing is equipped with grease nipple, is filled in the space between the splined shaft and spline housing in junction
Butter.
Due to using the above structure, passing through the effect of flange so that when power head inverts, threaded connector and power head master
Axis will not loosen, and in the power head course of work, compressed gas passes through the piston rod seals and the described first O-shaped sealing
Circle, the second O-ring seal are sealed, and the impact vibration that impactor generates acts through the first cushion pad and is eased, spline
The second cushion pad between axis and spline housing can mitigate collision effect when shadoof, and two cushion pads can mitigate when unloading bar
Damage to screw thread.
In conclusion a kind of hidden hole drilling power head buffer unit provided by the invention, not only has vibration damping, buffering, protection
The effect of screw thread also has certain guiding role, and has locking functions between dynamic head main spindle.

Specific implementation mode
The present invention will be further described in conjunction with the embodiment in attached drawing below：
Referring to Fig. 1 and Fig. 2, threaded connector 1 is threadedly coupled to by API on dynamic head main spindle 16,7 bottom of spline housing dress
Enter the second cushion pad 11, splined shaft 8 is inserted in spline housing 7, sleeve 12 is placed in splined shaft 8 and threaded connector 1, sleeve 12
It is upper that piston rod seals 14 are housed, dustband 10 and grease nipple 6, spline housing 7 and 1 end face of threaded connector are housed on spline housing 7
Between be equipped with the first O-ring seal 3, between threaded connector and dynamic head main spindle 16 be equipped with the second O-ring seal 15, spline housing 7,
Threaded connector 1 is linked together with flange 2 by bolt 4, spring washer 5, elastic cylindrical pin 9, splined shaft 8 be threadedly coupled
The first cushion pad 13 is lined between first 1.When power head works, compressed gas is carried out by O-ring with piston rod seals close
Envelope, load torque is transmitted to threaded connector by spline pair, bolt, elastic cylindrical pin, and then is transferred to power head.
