The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described further.
As shown in Figure 1 to 4, the integrated brill of the present embodiment cuts boring rod set, comprises drilling rod main body 1, sealing of hole assembly 2 and spurt hole assembly 3; The connection male 11 that described drilling rod main body 1 comprises the through hole that axially runs through and two ends pairing 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 faces, 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 the pressure to pressure spring for increasing hydraulic fluid; Described spurt hole assembly 3 is arranged in drilling rod main body, comprises jet flow through hole 311, and the through hole of jet flow through hole and drilling rod main body is vertical and be positioned at the rear of sealing of hole plug.Preferably, in the through hole of described drilling rod main body, be provided with jump ring, jump ring is used for limiting sealing of hole assembly.
Concrete, the pressure regulation plug of above-mentioned sealing of hole assembly comprises cylindricality cock body 232 and taper connection portion 231, the end face of cylindricality cock body and taper connection portion is in contact with one another and links together, wherein taper connection portion is for being connected with pressure spring, and cylindricality cock body makes pressure spring produce the pressure to sealing of hole plug by stopping hydraulic fluid.Cylindricality cock body and taper connection quality award from the ministry are elected integrated formed structure as.In order to increase the pressure of hydraulic fluid to spring, on the other end of described cylindricality cock body, comprise groove 233, described groove is for increasing the resistance to hydraulic fluid.
In device, through hole cuts with hydraulic fluid for delivery of brill, the connection male 11 of different drilling rods be connected female 12 and can interconnect, can form longer drilling rod.Wherein, jackrod structure is pipe-like, and there are the male of connection and female in two ends, and connection male and female can be preferably and 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 of carrying out mode of operation; Hydraulic fluid conventionally adopts water in engineering application, also can adopt other hydraulic fluids, and its object is mainly lower the temperature and under high pressure isolate coal seam for drilling rod boring procedure, and hydraulic fluid is preferably water here.
