Abstract
The utility model discloses a multifunctional drill rod with drilling, punching and fracturing functions. The drill rod is formed by a plurality of drill rod sections which are connected end to end; an annular step is arranged on the edge of the tail part of a front drill rod section, an annular bulge clamped with the annular step is arranged on the edge of the head part of a back drill rod section, and the annular bulge is higher than the annular step, so that space for accommodating a washer is formed after the annular bulge and the annular step are clamped. According to the multifunctional drill rod with the drilling, punching and fracturing functions, the annular step is arranged at the tail part of the front drill rod section, the annular bulge is arranged at the head part of the back drill rod section, and the front drill rod section and the back drill rod section are clamped through mutual matching of the annular step and the annular bulge, so that the front drill rod section and the back drill rod section are tightly connected through pressure of the drill rod during working; and meanwhile, the space for accommodating the washer is formed after the annular step and the annular bulge are matched, so that a bulged part of the head part of the back drill rod section and a recessed part of the tail part of the front drill rod section are tightly matched, and the integration of the drill rod after connection is enhanced to a certain extent.
Description
Technical field
The utility model relates to the drilling rod that field of coal mining is used, specifically a kind of brill, punching, pressure Multifunctional drill rod.
Background technology
Owing to often containing methane gas in coal seam, for guaranteeing production safety, before working seam, need gas wherein to extract out, be generally to adopt rig by coal bed drilling, extraction gas wherein then just can working seam.But only depend on gas automatically to discharge, its inefficiency, is difficult to meet need of production.In order to improve gas release efficiency, now water under high pressure is passed in bored hole, by coal bed fracturing, gas is discharged quickly.Existing operation process is more loaded down with trivial details, first boring, and then punching, last pressure break, use can not be used for pressure break due to used drilling rod time is repeatedly changed drilling rod and pressure break pipe in this process, and operating efficiency is extremely low.
Utility model content
For solving the problem of repeatedly changing drilling rod and pressure break pipe in prior art, the utility model provides a kind of brill, punching, pressure Multifunctional drill rod, once installs drilling rod additional, can realize the multiple working procedures such as brill, punching, pressure break.
The utility model is that the technical scheme that solves the problems of the technologies described above employing is: a kind of boring, punching, press Multifunctional drill rod, this drilling rod forms by multistage drilling rod is end to end, the middle part of last drill pipe section afterbody has round table-like depressed part, the middle part of a rear drill pipe section head has the protuberance matching with the depressed part of last drill pipe section afterbody, edge at last drill pipe section afterbody has circular step, there is the annular projection fastening with circular step at the edge of a rear drill pipe section head, and the height that the height of annular projection is greater than circular step has so that both cards screw rear formation the space that holds packing ring.
Described gasket rings is around the protuberance setting of a rear drill pipe section head.
Beneficial effect: the utility model is by arranging circular step in last drilling rod docking portion, a rear drill pipe section head arranges annular projection, both cooperatively interact and realize the clamping of front and back drill pipe section, pressure while utilizing like this drilling rod work closely connects both, simultaneously, after circular step and annular projection cooperation, also form a space that prevents packing ring, after can making, the protuberance of a drill pipe section head and the depressed part of last drill pipe section afterbody closely cooperate, play sealing function, can pass into water under high pressure in drilling rod time, there will not be leakage phenomenon.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Reference numeral: 1, a rear drill pipe section head, 101, protuberance, 102, annular projection, 2, last drill pipe section afterbody, 201 depressed parts, 202, circular step, 3, packing ring.
The specific embodiment
As shown in the figure, a kind of boring, punching, press Multifunctional drill rod, this drilling rod forms by multistage drilling rod is end to end, the middle part of last drill pipe section afterbody 2 has round table-like depressed part 201, the middle part of a rear drill pipe section head 1 has the protuberance 101 matching with the depressed part 201 of last drill pipe section afterbody 2, there is circular step 202 at the edge of last drill pipe section afterbody 2, there is the annular projection 102 fastening with circular step 202 at the edge of a rear drill pipe section head 1, and the height that the height of annular projection 102 is greater than circular step 202 has so that both cards screw rear formation the space that holds packing ring 3.
Described packing ring 3 arranges around the protuberance 101 of a rear drill pipe section head 1.
Claims (2)
1. a brill, punching, press Multifunctional drill rod, this drilling rod forms by multistage drilling rod is end to end, the middle part of last drill pipe section afterbody (2) has round table-like depressed part (201), the middle part of a rear drill pipe section head (1) has the protuberance (101) matching with the depressed part (201) of last drill pipe section afterbody (2), it is characterized in that: there is circular step (202) at the edge of last drill pipe section afterbody (2), there is the annular projection (102) fastening with circular step (202) at the edge of a rear drill pipe section head (1), and the height that the height of annular projection (102) is greater than circular step (202) has so that both cards screw rear formation the space that holds packing ring (3).
2. a kind of brill according to claim 1, punching, pressure Multifunctional drill rod, is characterized in that: described packing ring (3) arranges around the protuberance (101) of a rear drill pipe section head (1).
