Abstract
A kind of combined down-hole hammer sealing locknut structure, including pore damping adjustment device, connects nozzle, pressing plate, sealing gasket, bolt, spring washer, round nut, impacter top connection, location tapered sleeve, and impacter top connection is locked to locating cone by round nut and puts；Connect nozzle by using pressing plate, sealing gasket, bolt and spring washer circle to be pressed in impacter top connection；Connect on nozzle equipped with pore damping adjustment device, it is possible to adjust air inflow size；Impacter top connection with connect nozzle and locating cone inner room is taper-face contact, due to thrust effect and the coupling mechanism force effect of round nut of gland, elastic deformation occurring between the contact surface of two pairs of conical surface pairs, laminating is closely, bigger frictional force can be produced, thus the effect of sealing locknut can be played.
Description
Technical field
This utility model relates to a kind of combined down-hole hammer sealing locknut structure, it is adaptable on combined down-hole hammer.
Background technology
In large diameter bored pile is constructed, when running into air slaking severely-weathered, middle or even mild wind bedrock formation, if still
Using conventional engineering method and drilling tool will meet difficulty, often drilling depth is slow, the most at all cannot drilling depth, not only construction cost height, and
And construction quality is difficult to ensure that.DTH drilling is considered as to tackle the method that hard formation is the most reasonable and advanced at present.Down-hole hammer
Integral type down-hole hammer and combined down-hole hammer can be divided into by structure, owing to integral type down-hole hammer manufacturing cost is high, rush during work
Hitting vibration big, noise is high, and combined down-hole hammer is simple to manufacture, and during work, impact shock is little, and noise is low, and use cost is low, institute
It is a kind of preferably large diameter bored pile construction equipment with combined down-hole hammer.Combined down-hole hammer is owing to being by multiple punchings
Hit device to be used in combination, so the sealing locknut effect of its impacter is to the service efficiency of combined down-hole hammer and life-span shadow
Ring the biggest.
Generally in combined down-hole hammer, the sealing of impacter generally uses O sealing, and locking general employing double nut is locked
Tight or join the mode welding spacing clamp.The mode of double nut locking is carried out owing to only leaning on the end contact of nut to produce frictional force
Locking, contact area is little, and anti-loosing effect is bad.Impacter mounting bracket is joined the spacing clamp of weldering, though being possible to prevent impacter
Get loose, but operation inconvenience, join weldering error greatly, affect the installation accuracy of impacter.
Utility model content
This utility model overcomes the deficiencies in the prior art to provide a kind of sealing property reliable, and anti-loosing effect is good, structure letter
Single, it is possible to effectively to prevent the loosening of the leakage of combined down-hole hammer in use compressed gas and impacter, come off, improve
The combined down-hole hammer sealing locknut structure of the service efficiency of combined down-hole hammer.
The combined down-hole hammer sealing locknut structure that this utility model provides, including pore damping adjustment device, connects nozzle, pressure
Plate and impacter top connection, the inlet port of described impacter top connection be inserted in the tapered sleeve of location after again by nut check, institute
It is provided with in stating the air inlet of impacter top connection and connects nozzle, the longitudinal section of the inlet port inlet channel of described impacter top connection
For inverted trapezoidal, described in connect the lateral surface of nozzle and the mating shapes of inlet channel.
The described nozzle that connects is fixed on nut by pressing plate.
It is provided with sealing gasket between described pressing plate and nut joint face.
Described pressing plate is connected by bolt, spring washer with nut.
Inside the tapered sleeve of described location, the longitudinal section of hollow parts is trapezoidal, and described impacter top connection is connected with location tapered sleeve
The mating shapes of hollow parts inside the lateral surface at place and location tapered sleeve.
Described connect on nozzle equipped with pore damping adjustment device.
Use technique scheme combined down-hole hammer sealing locknut structure, compared with prior art, due to connect nozzle and
Impacter top connection junction uses the conical surface to connect, and contact area is big, and closely, friction anti-loosing effect is good in contact surface laminating, seals
Reliably；Additionally being also adopted by taper-face contact location between impacter top connection and location tapered sleeve, centering precision is high, and boring is difficult to partially
Tiltedly.
Accompanying drawing explanation
Fig. 1 is the structural representation that this utility model is arranged on combined down-hole hammer.
Fig. 2 is the partial enlarged drawing in Fig. 1 at I.
Label in figure: 1-combined down-hole hammer, 2-pore damping adjustment device, 3-connects nozzle, 4-bolt, 5-spring washer,
6-pressing plate, 7-sealing gasket, 8-round nut, 9-positions tapered sleeve, 10-impacter top connection.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment with the utility model is described in further detail.
See Fig. 1 and Fig. 2, impacter top connection 10 is penetrated in the tapered sleeve 9 of location, will connect on impacter with round nut 8
10 lockings, by the internal taper hole connecing nozzle 3 and loading impacter top connection 10, sealing gasket 7 and pressing plate 6 are set to connect on nozzle 3 successively, use
Sealing gasket 7 and pressing plate 6 are connected on round nut 8 by bolt 4 and spring washer 5, will connect nozzle 3 simultaneously and compress downwards, then by pore
Damping adjustment device 2 loading connects in nozzle, is used for regulating air inflow.When combined down-hole hammer 1 works, compressed gas is through connecing nozzle
3 enter impacter top connection 10, tight with the taper-face contact of impacter top connection 10 internal taper hole owing to connecing nozzle 3, form the conical surface close
Envelope, gas fully enters inside impacter, drives impacter acting；Impacter top connection 10 male cone (strobilus masculinus) passes through with location tapered sleeve 9
The coupling mechanism force effect of round nut 8, the conical surface is tightly combined, and contact area is big, produces the biggest frictional resistance, it is possible to plays sealing and makees
With with prevent impacter loose or dislocation.
These are only preferred embodiment of the present utility model, and limit this never in any form, for this area
For technical staff, this utility model can have various change and modification.All within spirit of the present utility model and principle, institute
Any change of work, equivalent, modification, improvement etc., within should be included in protection domain of the present utility model.Therefore, originally
The protection domain of utility model should be as the criterion with the protection domain of claims.
