Background technology
The requirement of strength that improves constantly column of variation of the structure of building and height constantly increases, and promptly requires the rotary drilling rig drilling diameter to increase, the hole depth lengthening, so it is also more and more common to run into the situation of hard formation in the drilling process.The working method of rotary drilling rig is low to the drilling efficiency of hard rock at present, especially be difficult to creep into for competent bed, the main solution of reply present situation is earlier with vibrating hammer the mode of creeping into again to be smashed in the rock stratum, phenomenons such as the very low and hole that occurs easily collapsing of efficient.A new drilling technology scheme was proposed before the applicant, be to adopt impact grinding+brill tooth cutting way, the impact force that tube bores the top impactor when both having utilized hard rock to impact the work of tube drill bit directly acts on rock it is smashed, the work of creeping into is finished in the utilization brill tooth cutting simultaneously mode of cracked rock, appeal two functions in boring first revolution work period, are once realized by the impact tube and continuous periodic duty, high efficiency and with low cost, and need in the technical program could drive its work to continual hydraulic oil or the Compressed Gas of providing of drilling tool.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, can delivery hydraulic pressure oil in drilling process or the telescopic drill rod of Compressed Gas.
The utility model telescopic drill rod, comprise the internal segment drilling rod, described internal segment drilling rod successively is socketed with some acromere drilling rods outward, the upper end of internal segment drilling rod is provided with and is used for the last connector that is connected with elevator, the lower end is provided with and is used for the following connector that is connected with drilling tool, wherein said going up between connector and the following connector is provided with at least one appendix or at least two hydraulic tubes, described appendix or hydraulic tube are positioned at the internal segment drilling rod, its upper end is connected with the connecting hole offered on the last connector, offer and appendix or the corresponding gas-liquid through hole of hydraulic tube quantity in the connector under described, described appendix or hydraulic tube are connected with the inner of gas-liquid through hole respectively, and the outer end of described gas-liquid through hole is used for being connected with the work gas-liquid mouth of drilling tool.
The utility model telescopic drill rod, wherein said connecting hole upper end also is provided with the gas-liquid flexible pipe, and the lower end of described gas-liquid flexible pipe is connected with appendix or hydraulic tube by connecting hole, and the upper end of gas-liquid flexible pipe is connected with the gas-liquid pumping plant.
The utility model telescopic drill rod, wherein said appendix or hydraulic tube are rigid pipe, are connected by joint between described gas-liquid flexible pipe and appendix or the hydraulic tube.
The utility model telescopic drill rod, wherein said appendix or hydraulic tube are flexible pipe, and described gas-liquid flexible pipe and appendix or hydraulic tube are connected as a single entity.
The utility model telescopic drill rod, the bottom of wherein said internal segment drilling rod is provided with damping device.
The utility model telescopic drill rod difference from prior art is to be provided with the hydraulic tube of delivery hydraulic pressure oil or to carry compressed-air actuated appendix in the internal segment drilling rod of the utility model telescopic drill rod, by hydraulic tube in the drilling rod or appendix hydraulic oil or compressed air delivery are arrived in the drilling tool of drilling rod lower end, drive the work that drilling tool is finished impact grinding+brill tooth cutting.
Below in conjunction with accompanying drawing telescopic drill rod of the present utility model is described further.
Description of drawings
