Abstract
The utility model discloses a high wind pressure downhole air hammer which comprises a cylinder body (5), a joint (1), an inverted valve, an air distributing seat (4), a piston (7) and a drill head (10).The cylinder body (5) is provided with a positioning retainer ring (6) corresponding to the piston (7) inside. The inverted valve is of a tapered inverted valve (3). The joint (1) is provided with antifriction alloy (2). The drill head (10) is installed on the cylinder body (5) through a snap ring (9). The drill head (10) is linked with the cylinder body (5) through a spline. The utility model relates to a high wind pressure downhole air hammer which has fast cutting rate, long service life, simple and reliable structure and convenient operation.
Description
Technical field
The utility model relates to a kind of impactor, particularly relate to be applied to dig up mine, the high blast down-the-hole air hammer of some blasting workss of power station, harbour, speedway, urban construction.
Background technology
High blast down-the-hole air hammer is widely used in digging up mine, some blasting workss of power station, harbour, speedway, urban construction, the piling of building site, sink wells etc.Its basic structure is to be provided with joint, non retern valve, distribution seat, piston and drill bit in cylinder body, adopts the outer shell distribution.Large increase along with present rig and air compressor machine technology, the wind pressure of work ratio wind pressure of work several years ago that offers impactor has now improved greatly, had only several blast (7～10) in the past, at least all have more than 14 now, generally be about 20 blast, reach more than 40 blast in addition, occur the air compressor machine of 70 blast abroad even all, therefore, adopt the outer shell distribution, be to have many air slots, make the inboard wall of cylinder block attenuation, can not satisfy the duty of this high blast at inboard wall of cylinder block, exist cutting rate slow, application life is short, and is simple and reliable for structure, inconvenient operation.
The utility model content
It is fast that technical problem to be solved in the utility model provides a kind of cutting rate, and long service life is simple and reliable for structure, easy to operate high blast down-the-hole air hammer.
In order to solve the problems of the technologies described above, the high blast down-the-hole air hammer that the utility model provides comprises cylinder body, joint, non retern valve, distribution seat, piston and drill bit, is provided with the positioning retainer ring corresponding with described piston in described cylinder body.
Described non retern valve is the taper non retern valve.On described joint, be provided with antifriction alloy.Described drill bit is installed on the described cylinder body by snap ring, and described drill bit and described cylinder body adopt splined.
Adopt the high blast down-the-hole air hammer of technique scheme,, reduced the quantity of cylinder body grooving, the cylinder body life-span is prolonged owing in cylinder body, be provided with the positioning retainer ring corresponding with piston.Non retern valve is the taper non retern valve, makes distribution more unimpeded.On joint, be provided with antifriction alloy, the application life of the cylinder body that extended.Drill bit is installed on the described cylinder body by snap ring, and described drill bit and described cylinder body adopt splined, carry-over moment.This high blast down-the-hole air hammer is widely used in digging up mine, some blasting workss of power station, harbour, speedway, urban construction, the piling of building site, sink wells etc.Be a kind of engineering machinery of high-efficiency low energy consumption, topmost characteristics are that cutting rate is fast, and long service life is simple and reliable for structure, easy to operate.
In sum, the utility model is that a kind of cutting rate is fast, and long service life is simple and reliable for structure, easy to operate high blast down-the-hole air hammer.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to accompanying drawing, joint 1, taper non retern valve 3, distribution seat 4, piston 7, nylon tube 8 and drill bit 10 are installed in cylinder body 5, in cylinder body 5, be provided with the positioning retainer ring 6 corresponding with piston 7, on joint 1, be provided with antifriction alloy 2, drill bit 10 is installed on the cylinder body 5 by snap ring 9, and drill bit 10 adopts splined with cylinder body 5.
Referring to accompanying drawing, owing in cylinder body 5, be provided with the positioning retainer ring 6 corresponding, reduced the quantity of cylinder body 5 groovings with piston 7,5 life-spans of cylinder body are prolonged.Non retern valve is a taper non retern valve 3, makes distribution more unimpeded.On joint 1, be provided with antifriction alloy 2, the application life of the cylinder body 5 that extended.Drill bit 10 is installed on the cylinder body 5 by snap ring 9, and drill bit 10 can not be fallen any more when work, and drill bit 10 adopts splined, carry-over moment with cylinder body 5.
Referring to accompanying drawing, its operating principle is:
Gas enters impactor from joint 1 interstitial hole, wash taper non retern valve 3 open and enter the impactor back cavity, circle hole by distribution seat 4 tops enters in the middle of the impactor again, then by positioning retainer ring 6, enter the impactor ante-chamber from the groove of piston 7, owing to lived owing to the card drill sleeve is airtight foremost, when ante-chamber gas reaches some, just force piston 7 upwards to improve, bring up to certain altitude, when reaching the height of nylon tube 8 of drill bit 10 when piston 7, gas is just discharged by drill bit 10 from nylon tube 8, this moment because, piston 7 is in certain altitude, and ante-chamber pressure is less than back cavity pressure, piston 7 is just laid at a high speed thus, hit drill bit 10, drill bit 10 is owing to severe impact smashes rock, simultaneously, because drilling rod drives impactor and rotates in a circumferential direction, so drill bit 10 also rotates in a circumferential direction by the certificate of turning round of spline transmission, thereby will axially grind towards broken large rock mass, by gases at high pressure the rock disintegrating slag is blown out again.
