Utility model content
The purpose of this utility model is easily leaked in junction when passing into high-pressure cooling water for solving existing drilling rod and cause the problem of sealing effectiveness difference due to alignment error, provides a kind of water conservancy punching sealing drilling rod.
The utility model is the deficiency solved the problems of the technologies described above, and the technical scheme adopted is:
A kind of water conservancy punching sealing drilling rod, comprise the body of rod that plural intersegmental part is hollow structure, the described body of rod comprises boring section, be positioned at connector and the Connection Block at boring section two ends, described connector comprises taper thread joint outer wall being provided with taper thread and the linkage section I be connected to by taper thread joint in boring section, Connection Block comprises the taper thread seat offering taper thread hole and the linkage section II coordinated with linkage section I, the other end of taper thread joint is provided with raised section and forms the section of being tightly connected I, the end of taper thread seat offers one section of unthreaded hole and forms the section of the being tightly connected II coordinated with the section of being tightly connected I, the described section of being tightly connected I comprises raised section, the sealing ring being opened in the groove on raised section and being arranged in groove, the described section of being tightly connected II be inner wall smooth and just and sealing ring form the smooth surface be sealed and matched.
Cooling Holes through is along its length offered in the described body of rod.
The described body of rod offers chip area and chip area is U-type groove.
The described section of being tightly connected I is provided with positioning section away from one end of taper thread joint, the described section of being tightly connected II offers the locating hole coordinated with positioning section, transition face between locating hole and the section of being tightly connected II is smooth surface, sealing when ensureing that locating hole coordinates with positioning section.
The described section of being tightly connected I is one section of raised section in cylindrical shape, and the described section of being tightly connected II is a hole in cylindrical shape.
The beneficial effects of the utility model are: the utility model is provided with seal section, can ensure when passing into water under high pressure, junction sealing between each section of drilling rod tightly there will not be the situation of leaking, this ensures that there the hydraulic pressure in drilling rod, and on drilling rod, be provided with locating hole and positioning section decreases alignment error, avoid drilling rod, seal section is arranged on the seam crossing away from two drilling rod outsides simultaneously, and the transition face between locating hole and the section of being tightly connected II is that smooth surface constitutes the step surface protecting sealing ring, effectively solve the problem owing to installing the seal failure tilting to cause, each section adopts taper thread to connect simultaneously, easy for installation, offer chip area, make chip removal more smooth and easy.
