Abstract

A water inputting and returning pipe joint of a double-layer drill rod comprises an inner pipe and an outer pipe, wherein the inner pipe and the outer pipe are sleeved internally and externally and are connected in a fastening manner. A first joint and a second joint are formed in the inner pipe and the outer pipe respectively in the side direction. The water inputting and returning pipe joint is characterized in that a first fastening flange and a sealing connecting part which are connected in a sealing manner are sequentially arranged at the top end of the inner pipe from bottom to top, and the first fastening flange is connected with the top end of the inner pipe in a fastening manner; and the sealing connecting part is formed by head-to-tail connection of at least two first connecting parts in sequence, and first mounting holes communicated with bolt holes in the first fastening flange are correspondingly formed in the first connecting parts. Compared with the prior art, the water inputting and returning pipe joint of the double-layer drill rod is simple in structure and convenient to clean.

Description

technical field [0001] The invention relates to a water inlet and return pipe joint, in particular to a water inlet and return pipe joint suitable for double-layer drill pipes, and belongs to the field of mechanical technology. Background technique [0002] The connection between the casings of the traditional drilling rig is the same as described in the Chinese utility model patent "Multifunctional Drilling Rig" (authorized announcement number CN2304747Y) with the patent number ZL97227008.6: the drill pipe connected to the power head is equipped with a head Casing joint with clamping block, casing with casing drill bit at the tail, drill pipe, casing and output bushing of power head are connected together through drilling tool triple joint, the lower part of power head is installed with jaw lifter, The sleeve pipe is matched with the central hole of the claw lifting plate, and the claws of the claw lifting plate are matched with the internal thread of the sleeve joint, and ...
