Said invention possesses characteristics of simple structure, practicality, large impact power, high drilling efficiency and low cost, etc..
Description
The present invention relates to a kind ofly be used for that underground firm hard formation creeps into and the hydraulic in-the-hole hammer of battering ram pipe construction, belong to and creep into field of mechanical technique.
Existing at present comprehensive drilling construction and the higher pneumatic down hole hammer of efficient of can be used for, be subjected to self to limit and be difficult to deep hole and be rich in the water stratum construct, and the energy consumption height, noise is big, coordinative composition of equipments is expensive, though very high its capacity usage ratio of its ballistic work also has only below 10%.
And common hydraulic in-the-hole hammer, promptly the impact rotating drilling tool only utilizes the liquid water hammer, and capacity usage ratio is low, thereby can not export large impact energy, is difficult to produce in creeping into the volume detritus comprehensively.
The object of the present invention is to provide a kind of capacity usage ratio height, ballistic work is big, coordinative composition of equipments is simple and can be used for the hydraulic in-the-hole hammer of the exportable HI high impact merit of deep well drilling construction.
Technical solution of the present invention is: comprise shell 1, go up valve 2, block stamp 3, heart valve 4 and lower contact 5, it is characterized in that, last valve 2 adopts to insert mutually with block stamp 3 and cooperates, can produce the energy storage stroke in the backhaul stage, heart valve 4 reaches upward with block stamp 3, and valve 2 mates mutually, control current by pass 11 produces the standard-sized sheet full-shut position, and the bottom of block stamp 3 endoporus and heart valve 4 fitting faces is provided with radially drain hole 13.Make the block stamp backhaul effectively utilize the liquid energy, make cavity of resorption be in low back pressure state during stroke, improved capacity usage ratio.
The face of cylinder, last valve 2 top forms slipper seal with shell 1 and cooperates.
Reducing step 16 forms linear sealing under the heart valve 4 lower end conical surfaces and the block stamp endoporus.
Description of drawings:
Fig. 1 is a structural representation of the present invention
Among the figure 1, shell 2, go up valve 3, block stamp 4, heart valve 5, lower contact 6, uuper valve chamber 7, go up end play 8 between valve and block stamp, the topping bar 11, current by pass 12, go up valve bottom dead centre 13, reducing step under reducing step 16, the block stamp endoporus on drain hole 14, heart valve endoporus 15, the block stamp endoporus radially of block stamp through hole 9, cavity of resorption 10, block stamp.
Describe the present invention in detail below in conjunction with accompanying drawing:
Go up the face of cylinder, valve 2 top and shell 1 among the figure for slipper seal cooperates, last valve 2 adopts mutually with block stamp 3 that insertion cooperates, and heart valve 4 and block stamp 3 reach upward that valve 2 mates mutually, and heart valve 4 external cylindrical surfaces have longitudinal balance groove and block stamp 3 endoporus formation slipper seal.Heart valve 4 axially-movable strokes are subjected to reducing step 15 restrictions on block stamp 3 endoporus.Reducing step 16 forms linear sealing under the heart valve 4 lower end conical surfaces and the block stamp endoporus, and heart valve endoporus 14 diameters are the 5--500 millimeter.The bottom of block stamp 3 endoporus and heart valve 4 fitting faces is provided with radially drain hole 13.Block stamp 3 is that slipper seal cooperates with the endoporus of shell 1 and lower contact 5, is spline or polygonal inside and outside hole axial sliding fit between lower contact 5 and the shell 1.Its operating principle is as follows: go up valve 2 and block stamp 3 usually and be in bottom dead centre (shown in Figure 1).Arrive uuper valve chamber 6 when flushing liquor is sent into hydraulic in-the-hole hammer by drilling tool, the end play through between last valve and block stamp 7 enters block stamp through hole 8 again; When caring valve endoporus 14, because area of passage reduces to produce pressure differential and shifts heart valve onto bottom dead centre (as shown in the figure), make cavity of resorption 9 sealings set up pressure, will go up valve and shift top dead-centre onto, block stamp 3 also begins upwards to do accelerated motion simultaneously; Cavity of resorption 9 and uuper valve chamber 6 are disconnected, cavity of resorption 9 pressure reduce very soon, last valve 2 moves downward under action of pressure until its lower surface and contacts with step 10 on the block stamp, this moment, block stamp 3 entered the decelerating phase under the effect of piston pressure difference up and down, and the two common speed that goes upward to of slowing down is zero; Meanwhile heart valve 4 is because aneroid stream passes through, and the closing force that is produced by pressure differential disappears, and it does relative motion with block stamp under the self inertia effect, opened cavity of resorption current by pass 11.Block stamp 3 is done accelerated motion downwards with last valve 2 beginnings, and the current by pass 11 that the liquid of cavity of resorption 9 is opened by heart valve discharges, and this moment, the backhaul end stroke of block stamp began; Stop motion when last valve 2 arrives bottom dead centre 12, block stamp 3 still continues to do accelerated motion downwards, and this moment, upper cavity pressure reduced the downward active area of block stamp, and the block stamp acceleration reduces; When block stamp 3 continues motion beginning and 2 disengagements of last valve, end play 7 between block stamp and last valve is progressively opened, uuper valve chamber 6 is communicated with cavity of resorption 9, water under high pressure is pushed into heart valve 2 bottom dead centre sealing cavity of resorption 9 during by block stamp through hole 8 once more, block stamp 3 begins to enter the deceleration stroke and does upwards accelerated motion until impacting under lower contact 5 effects of back in area difference, moves upward under action of pressure and returns to top dead-centre and wait for the up once more of block stamp and go up valve this moment ... the impulse period second time of block stamp begins.Carry out and so forth.
Advantage of the present invention is:
Because 3 of last valve 2 and block stamps adopt mutual plug-in type fit structure, effectively the backhaul energy are converted into the stroke energy.Avoid the harmful impact of block stamp backhaul to hydraulic in-the-hole hammer; Heart valve 4 is with block stamp 3 and go up valve 2 and mate mutually, and control current by pass 11 produces the standard-sized sheet full-shut positions, makes the block stamp backhaul can effectively utilize the liquid energy, cavity of resorption is in hangs down the back pressure state, has improved capacity usage ratio.So that the present invention has is simple in structure, practical, ballistic work is big, drilling efficiency height, characteristics such as expense is low, and coordinative composition of equipments is simple.
