Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described further.
As shown in Figure 1 to 4, the integration of the present embodiment is bored and is cut boring rod set, comprises drill pipe body 1, sealing of hole assembly 2 and spurt hole assembly 3; The connection male 11 that described drill pipe body 1 comprises through hole and the two ends pairing axially run through be connected female 12, described through hole is pyramidal structure in one end of drilling rod; Sealing of hole assembly is positioned in through hole, comprise taper sealing of hole plug 21, pressure spring 22 and pressure regulation plug 23, the end face that taper sealing of hole plug 21 is larger is connected with pressure spring 22 1 end face, the other end of pressure spring connects pressure regulation plug 23, described sealing of hole plug mates with the pyramidal structure of through hole, for shutoff through hole, pressure regulation plug is for increasing the pressure of hydraulic fluid to pressure spring; Described spurt hole assembly 3 is arranged in drill pipe body, comprises jet through hole 311, and jet through hole is vertical with the through hole of drill pipe body and be positioned at the rear of sealing of hole plug.Preferably, be provided with jump ring in the through hole of described drill pipe body, jump ring is for limiting sealing of hole assembly.
Concrete, the pressure regulation plug of above-mentioned sealing of hole assembly comprises cylindricality cock body 232 and cone connection 231, the end face of cylindricality cock body and cone connection contacts with each other and links together, wherein cone connection is used for being connected with pressure spring, and cylindricality cock body is by stopping that hydraulic fluid makes the pressure of pressure spring generation to sealing of hole plug.Cylindricality cock body and cone connection are preferably integrated formed structure.In order to increase the pressure of hydraulic fluid to spring, the other end of described cylindricality cock body comprises groove 233, described groove is for increasing the resistance to hydraulic fluid.
In a device, through hole cuts with hydraulic fluid for carrying brill, the connection male 11 of different drilling rod be connected female 12 and can interconnect, longer drilling rod can be formed.Wherein, jackrod structure is pipe-like, and there are connection male and female in two ends, and connection male and female can preferably be threaded; Through hole is similar to funnel structure in the pyramidal structure of one end of drilling rod, for coordinating with sealing of hole assembly the switching carrying out mode of operation; Hydraulic fluid usually adopts water in engineer applied, also can adopt other hydraulic fluids, and its object is mainly lowered the temperature for drilling rod boring procedure and under high pressure isolated coal seam, and hydraulic fluid is preferably water here.
As shown in Figure 2, described sealing of hole assembly 2 comprises conical sealing of hole plug 21 and pressure spring 22, freely be positioned in through hole after the larger end face of conical sealing of hole plug 21 is connected with pressure spring 22 1 end face, the diameter of the larger end face of described sealing of hole plug 21 is greater than the minimum diameter of described through hole pyramidal structure, and described pressure spring 22 is for acting on according to the pressure of described hydraulic fluid on sealing of hole plug 21 to make drilling rod 1 change between boring and cutting two functions; Above-mentioned transfer process mainly because when the pressure increase of hydraulic fluid is that pressure spring is subject to the blastic deformation of hydraulic fluid, produces the pressure to sealing of hole plug, make the through hole of drilling rod be blocked, and then forces hydraulic fluid to isolate coal seam from jet pack ejection.But due to pressure spring to accept area less, easily cause sealing of hole plug not easily to secure when shutoff drilling rod through hole.
As shown in Figure 3, the spurt hole assembly 3 of the present embodiment comprises the jet through hole 311 be arranged at along through hole described in the radial UNICOM of drilling rod 1 and space outerpace in drilling rod 1 main body, and the position of described jet through hole 311 meets the height that its distance to drilling rod pyramidal structure place end face is greater than taper sealing of hole plug 21.Its operating principle is as follows: taper sealing of hole plug is consistent with the external diameter of pressure spring, and be less than the through hole internal diameter of drilling rod, sealing of hole assembly is put into drilling rod through hole and can be free to slide, when fluid pressure is less, it is also less to the pressure of pressure spring and sealing of hole plug, the blocking dynamics of sealing of hole plug to through-hole passage is less, therefore most of liquid flows to drill bit to ensure that boring is normally carried out from the gap of sealing of hole plug and through hole, when fluid pressure increase to a certain degree such as to 8MPa-10MPa time, pressure spring and sealing of hole plug are subject to the huge pressure of liquid and almost the shutoff through hole of drilling rod (does not now block drilling rod through hole completely, some liquid flows through to cool drill bit from the gap between sealing of hole plug and drilling rod), a large amount of highly pressurised liquid is spouting from the spurt hole assembly of drilling rod, namely the high-pressure spray ejected can be used for isolating coal seam.So, after adopting this drilling rod, by the conversion regulating the pressure of supply hydraulic fluid can realize boring and cutting function, and target drill need not be changed, greatly save the duration.
As shown in Figures 1 and 3, spurt hole assembly 3 is preferably removable sinking bolt arrangement, specifically comprise on drilling rod 1 along the sinking bolt thread hole 32 that drilling rod 1 radial direction is arranged and corresponding sinking bolt 31, described sinking bolt 31 comprises jet through hole 311, and described jet through hole 311 axis overlaps with sinking bolt shaft 31 line.The spurt hole assembly of above-mentioned sinking bolt arrangement is the preferred version of the present embodiment, because jet through hole needs to bear very high pressure usually, therefore be hold one of flimsy parts, adopt the jet through hole structure of this sinking bolt that the flimsy jet through hole of appearance and drilling rod can be made to separate, can be made up by the sinking bolt changing spurt hole assembly when jet through hole breaks down, can use cost be reduced, economize on resources.
Further, above-mentioned jet through hole 311 is designed to the little horn mouth shape of import large outlet, to improve the effect of isolating jet further.Because cutting coal seam depends on the high-pressure energy of hydraulic fluid, but because jet through hole shape is different, the extent of damage differs greatly when high-pressure energy sprays from jet through hole, when usual horn mouth airflow design can must ensure that liquid sprays very well, the loss of its high-pressure energy is less, therefore in the preferred version of the present embodiment, adopt the jet through hole of the horn mouth shape that import large outlet is little to design.
The effect of the present embodiment is analyzed below for a concrete engineering:
Adopt the integration of the present embodiment to bore and cut drilling rod boring rod set due to without the need to repeating upper and lower drilling rod, therefore reduce the drilling construction time and can be expressed as follows: T=(L1/L2) × t1 × S1 × S2+T1; Wherein, T1=(L1/V) × 2 × S1 × S2, therefore T=(L1/L2) × t1 × S1 × S2+ (L1/V) × 2 × S1 × S2, in formula, each character implication is as follows: T saves time (min), L1 single hole length (m), L2 run of steel (m), the t1 upper and lower bar time (every root) (min), S1 each drilling holes at the drilling yard number (individual), the drill site number (individual) that S2 needs waterpower to cut, V fltting speed (pushing away empty speed) (m/min).
For a certain engineering, assuming that its drilling depth requires L1=36m, run of steel L2=0.8m, upper lower beam time t1=1min, each drilling holes at the drilling yard number S1=10, needs the drill site number S2=181 cut in water, fltting speed (pushing away empty speed) V=10m/min, then save time T=(36/0.8) × 1 × 10 × 181+36/10 × 2 × 10 × 181=94482min, i.e. about 65.61 days of T=.Drawn by result of calculation, for the engineering being similar to above-mentioned drill site parameter, 65.61 days approximately in advance duration of a project will be made after adopting the drilling rod of the present embodiment, greatly improve engineering efficiency, reduce engineering cost.
