Abstract
A high-low pressure seal drill rod for hydraulic flushing comprises a plurality of sections of rod bodies. Each rod body adopts a hollow structure and comprises a drilling section, a connector and a connecting seat, wherein the connector and the connecting seat are arranged at the two ends of the drilling section; the connector comprises a taper-thread joint and a seal section I; the outer wall of the taper-thread joint is provided with a taper thread; the taper-thread joint is connected to the drilling section through the seal section I; the connecting seat comprises a taper-thread seat with a taper-thread hole, and a seal section II which is matched with the seal section I to realize sealing; the seal section I comprises a groove formed in the rod body and a seal ring mounted in the groove; the seal section II is a smooth surface which has a smooth inner wall and is just in seal fit with the seal ring. The high-low pressure seal drill rod for hydraulic flushing is provided with the seal sections, can ensure that the joints of all sections of the drill rod are sealed closely and cannot leak water when high-pressure water is injected, and guarantees hydraulic pressure to a drill bit.
Description
Technical field
The utility model relates to a kind of mining drilling device, especially relates to a kind of water conservancy punching high-low pressure sealing drilling rod.
Background technology
In engineering geology and mineral reserve probing, be widely used drilling rod, especially in coal mining, need to punch in order to draw out methane, because hole is deep, therefore need to use drilling rod, but be the cooling water of pressure at 1MPa-40MPa for the convenient punching of cooling drill bit sometimes needs to pass into water under high pressure, and adopt existing drilling rod often to appear at the situation that junction leaks, so not only make to arrive the water shortage of drill bit, simultaneously hydraulic pressure also can step-down, and impact is used.
Utility model content
The purpose of this utility model is the problem of easily leaking in junction in the time passing into high-pressure cooling water for solving existing drilling rod, a kind of water conservancy punching high-low pressure sealing drilling rod is provided, the utility model is provided with seal section, can ensure in the time passing into water under high pressure, junction sealing between each section of drilling rod tightly there will not be the situation of leaking, ensure to arrive the hydraulic pressure of drill bit, ensured that cooling water arrives drill bit smoothly simultaneously, avoid because leak the accident causing, each section adopts taper thread to connect simultaneously, easy for installation, offer chip area, make chip removal more smooth and easy.
The utility model is the deficiency solving the problems of the technologies described above, and the technical scheme adopting is:
A kind of water conservancy punching high-low pressure sealing drilling rod, comprise that plural intersegmental part is the body of rod of hollow structure, comprise that the described body of rod comprises boring section, be positioned at connector and the Connection Block at boring section two ends, described connector comprises and on outer wall, is provided with the taper thread joint of taper thread and taper thread joint is connected to the seal section I in boring section, Connection Block comprises offering the taper thread seat in taper thread hole and coordinating with seal section I realizes the seal section II sealing, described seal section I comprises the groove being opened on the body of rod and is arranged on the sealing ring in groove, described seal section II be inner wall smooth and just and sealing ring form the smooth surface being sealed and matched.
In the described body of rod, offer the Cooling Holes connecting along its length.
On the described body of rod, offering chip area and chip area is U-shaped groove.
The beneficial effects of the utility model are: the utility model is provided with seal section, can ensure in the time passing into water under high pressure, junction sealing between each section of drilling rod tightly there will not be the situation of leaking, the hydraulic pressure that has ensured to arrive drill bit has ensured that cooling water arrives drill bit smoothly simultaneously, avoids because leak the accident causing, each section adopts taper thread to connect simultaneously, easy for installation, offer chip area, make chip removal more smooth and easy.
