The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Be depicted as first embodiment of a kind of multifunctional high pressure churning segmentation reaming bit of the present invention like Fig. 1,2, comprise drill body 1, front end nozzle 2, side nozzle 3, dwang 4, dwang axis of rotation 5, first high-pressure channel 6, second high-pressure channel 7, joint 8, high-pressure channel control device 9; Said front end nozzle 2 is positioned at the non-central position of the front end of drill body 1; Said front end nozzle 2 is connected with first high-pressure channel 6 that is arranged on drill body 1 inside; Said dwang 4 can be arranged on the side of drill body 1 rotatably around dwang axis of rotation 5; Said side nozzle 3 is arranged on the outer end of dwang 4, and said side nozzle 3 is communicated with second high-pressure channel 7; Said second high-pressure channel 7 is made up of the pipeline in the inner a part of pipeline of drill body, high-pressure hose and the dwang, and is formed a fluid flow passage; Said first high-pressure channel 6, second high-pressure channel 7 are communicated with joint 8 respectively; Said high-pressure channel control device 9 is used for controlling the unlatching of first high-pressure channel 6, second high-pressure channel 7 or cuts out, and the passage that promptly is used for selecting fluid to circulate is first high-pressure channel 6 or second high-pressure channel 7; When beginning to hole, the unlatching of said high-pressure channel control device 9 controls first high-pressure channel 6, second high-pressure channel 7 is closed, and promptly fluid can enter into front end nozzle 2 through first high-pressure channel 6; The fluid pressure of this moment is less; When multifunctional high pressure churning segmentation reaming bit that the present invention program's first implements enters in the hole of just being bored; Control high-pressure channel control device 9; Second high-pressure channel 7 is opened; Be that fluid can enter into side nozzle 3 through second high-pressure channel 7, high-pressure fluid can carry out reaming, and the fluid pressure of this moment is big.In entire work process, said multifunctional high pressure churning segmentation reaming bit is in the rotation always.Embodiment of the invention scheme has comprised front end nozzle 2 and side nozzle 3; Front end nozzle 2 can spray the work that cutting realizes boring to the soil body of chisel edge; Side nozzle 3 is arranged on the dwang 4; Said dwang 4 can make side nozzle 3 away from drill body 1 around 5 rotations of the dwang axis of rotation on the drill body 1, to satisfy the needs of segmentation reaming.First embodiment of the present invention scheme has these two kinds of same drill bits of functional utilization and realizes, in construction, has simplified and has pulled out drilling rod time of bit change more, has improved construction efficiency greatly.
Like second embodiment of accompanying drawing 3, the of the present invention a kind of high-pressure rotary-spray segmentation reaming bit shown in 4, comprise drill body 11, front end nozzle 12, side nozzle 13, dwang 14, dwang axis of rotation 15, main channel pipe 16, spring 17, unidirectional baffle plate 18, subchannel 19, bar shaped tooth bar 20, gear 21, joint 22; Said front end nozzle 12 has 3, is separately positioned on the front end of drill body 7, and one of them front end nozzle 12 is arranged on the centre bit of the front end of drill body 7, and other two front end nozzles 12 are arranged on the sidepiece of the front end of drill body 7; Said main channel pipe 16 is arranged on the inside of drill main body 11; Be provided with spring 7 between the front end of said main channel pipe 16 and the drill body 7; The set inside of said main channel pipe has main channel (not indicating); Said main channel pipe is communicated with 3 front end nozzles 12 respectively; Said unidirectional baffle plate 18 is inner in the main channel; The outer setting of said main channel pipe 16 has bar shaped tooth bar 20; 2 dwangs 14 are arranged among the present invention program; Each dwang 14 can be rotatably set on the sidepiece of drill body 11 through dwang axis of rotation 15; Said side nozzle 13 is arranged on the outer end of dwang 14; Said side nozzle 13 is communicated with subchannel 19; Said subchannel 19 is made up of the pipeline in the inner a part of pipeline of drill body, high-pressure hose and the dwang, and is formed a fluid flow passage; The outer setting of the rotating part of said dwang has gear 21; Said gear 21 cooperates installation with bar shaped tooth bar 20; Said main channel is communicated with joint respectively with subchannel 19.
The use of the present invention program's second embodiment: during boring, the unidirectional baffle plate 18 in the main channel pipe 16 in opened condition, front end nozzle 12 can spray the work that cutting realizes boring to the soil body of chisel edge; When the needs reaming; Improve the pressure of fluid, original balance of main channel pipe 16 is broken, and high-pressure fluid promotes main channel pipe 16 motion forward; Simultaneously; Unidirectional baffle plate 18 gradually to closed condition conversion, the high-pressure fluid main channel is managed 16 thrust and can be come also greatly more like this, directly ends unidirectional baffle plate 18 and closes fully; Bar shaped tooth bar 20 is along with main channel pipe 16 motion forward always in this process, the motion of bar shaped tooth bar 20, and the rotation of driven gear 21, thus realize that dwang 14 more and more departs from drill main body 11; At this moment, can carry out the segmentation reaming.Second embodiment of the present invention scheme has boring, these two kinds of functions of reaming, in construction, has simplified and has pulled out drilling rod time of bit change more, has improved construction efficiency greatly; Simultaneously; Because the pressure that the rotation of dwang 14 is produced by high-pressure fluid produces main channel pipe 16 and moves; Drive dwang 14 by the bar shaped tooth bar on the main channel pipe 16 20 again and cog, dwang is rotated, thereby the rotation meeting of dwang 14 is highly stable; Like this can with dwang 14 do long, the high-pressure fluid that sprays through the side nozzle on the dwang 14 13 can carry out the reaming bigger than prior art; And the anglec of rotation of control dwang 14 can be carried out the reaming of different radii.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
