Description
Technical field
The present invention relates to a kind of down-the-hole air hammer, is dived more particularly to a kind of highly reliable easy care deep hole operation
Hole impactor, belong to mining machinery technical field.
Background technology
The quick down-the-hole air hammer of Vehicles Collected from Market is mainly used in mine blasting, water well earth source, hill excavating and offshore filling engineering etc.,
Efficiency requirements more and more higher of the market to product.
The impactor of conventional type realizes that the impact of impactor is done work mainly by the distribution effect of inner casing and piston, with routine
Exemplified by A series, piston in addition to a middle through hole, itself without other holes exist among piston, piston move up and down according to
Inner cylinder coordinates with outside piston air flue, so that piston forms reciprocating motion, the gases at high pressure of piston movement between front and rear room
Enter the front and rear room of piston by the cavity between inner casing and outer tube.
Surveyed in addition, the non-return valve of conventional impactor is typically mounted in top connection, need to such as change non-return valve and spring portion
Part, top connection can only be removed, and be acted on using the top connection of process kind by revolving force, close, dismounting difficulty is coordinated with outer tube；This
Outside, the regulating the qi flowing in the channels plug of conventional impactor is single part, adjusted tolerance and need to take out and changed, and equally wasted time and energy；Furthermore often
Impactor is advised without pressure limiting device, once user's makes
With hypertonia, impactor piston spoilage is added significantly to, causes larger economic loss and duration to influence.
The content of the invention
The problem to be solved in the present invention is to provide a kind of simple and compact for structure, is easy to safeguard, improved gas efficiency,
And interior plenum system also to water well operation when obstruction have a certain degree of highly reliable easy care deep hole avoided
Operation down-the-hole air hammer.
In order to solve the above problems, the present invention uses following technical scheme：
Deep hole operation down-the-hole air hammer, including top connection, outer tube and drill bit, central aeration pipe distribution dress is installed in outer tube
Put and piston, central aeration pipe air distributing device connect top connection with piston, be provided with top connection non-return valve positioner and
Multigroup pressure limiting device for being used to control operating pressure, the end of central aeration pipe air distributing device is provided with for letting cinder control air quantity
Throughput self-checking device, gases at high pressure realize the high-frequency high-speed of piston by top connection and central aeration pipe air distributing device
Reciprocal acting motion.
It is further optimization of the present invention to such scheme below：
Non-return valve positioner includes being arranged on long-channel in top connection, close to the position of taper thread end face in long-channel
Non-return valve is provided with, the position corresponding with non-return valve end is provided with cooperation step in long-channel, coordinates and is provided with step
The obturating cup seat coordinated with non-return valve.
Further optimization：The other end of non-return valve is arranged with check valve spring, and extend into spring base, is set on spring base

When in use, as shown in Fig. 6, Fig. 7, Fig. 8, Fig. 9, gases at high pressure enter center to the throughput self-checking device
During breather pipe 5, when gas pressure exceedes setting value, it need not now increase delivery of bailing air, gases at high pressure compression seal valve 601 is complete
Enter entirely in Packing spring seat 603, gas is crossed gas passage 51 from strip completely and discharged, with being continuously increased for drilling well rice number, punching
The actual use pressure for hitting device gradually reduces；When being reduced to certain phase, it is less than the thrust of spring 602 at this stage using pressure
When, spring 602 promotes the displacement certain distance of sealing valve 601, now exposes the first round, gases at high pressure are shunted by the first round
Portion gas carries out deslagging；When pressure is again lowered to certain phase, spring 602 continues to press on the displacement of sealing valve 601, according to
Displacement exposes second row, the 3rd round etc., increases the gas passing area of mud hole indirectly, reaches the mesh for increasing tolerance
's.
In use, after gases at high pressure enter top connection 1, gases at high pressure compress the spring 3 of non-return valve 2, open for normal operation
Non-return valve 2 is opened, gases at high pressure are entered in central aeration pipe 5 by multiple gas passages 106 of crossing of spring base 4 afterwards, are passed through simultaneously
Pressure limiting device 16 carries out automatic Regulation, and the position that throughput self-checking device 6 adjusts sealing valve 601 by the pressure of gas is entered
Row deslagging, while gases at high pressure cross gas passage 51 into the first distribution duct on piston 7 by the strip of central aeration pipe 5
71st, in the second distribution duct 72；When piston 7 is descending, when strip crosses gas passage 51 and is located at 7 upper end of piston, strip crosses gas passage 51
Being connected with the second distribution duct 72, gases at high pressure enter cup 9 by the second distribution duct 72, so as to promote piston 7 up, when
Piston 7 is up, and when strip crosses gas passage 51 and is located at 7 middle part of piston, gases at high pressure pass through the first distribution duct 71 and enter rear chamber 10
It is interior, so as to promote piston 7 descending, move in circles, using piston 7 positioned at the diverse location in outer tube 8, realize that gases at high pressure lead to
Cross the first distribution duct 71, the second distribution duct 72 and enter the cup 9 and rear chamber 10 of piston distribution, realize the high-frequency high-speed of piston
Reciprocal acting motion.
When need it is strong blow operation when, impactor lift-off hole is low, and drill bit 11 is fallen, and piston 7 follows drill bit 11 to drop down onto to blow position by force
Put, now, strip is crossed gas passage 51 and is located in rear chamber 10, and gases at high pressure cross gas passage 51 by strip and are directly entered rear chamber 10,
Central passage 73 is entered by the first distribution duct 71 of piston 7 afterwards, is expelled directly out outside impactor, realization blows function by force.
The present invention can be matched somebody with somebody by changing four parts such as guide sleeve 13, outer tube 8, snap ring 14, lower contact 15
With the drill bit of different connection form, such as DHD series, QL series, SD series, Mission series, have good accessory general
Property and operability, realize a kind of gas distribution structure adapted plurality of specifications drill bit, expand use range.
For the present invention using piston from distribution principle, the design of no inner casing need not dismounting by new type check valve positioner
Top connection is the replaceable corresponding annex such as non-return valve and spring, and need not tear machine open by throughput self-checking device changes regulating the qi flowing in the channels plug
Automatically adjusting for delivery of bailing air can be achieved, with releasing pressure automatically impactor can be ensured in rational work pressure by pressure limiting device
Worked under power, it is compact-sized simple, be easy to safeguard, improved gas efficiency, and interior plenum system also to water well operation when resistance
Be plugged with it is a certain degree of avoid, expand use range, add the service life of impactor.
