Disclosure of Invention
The invention aims to provide an auxiliary device for centering a drill rod of an advanced drilling machine, which is used for pre-adjusting centering before the installation of the drill rod, realizing safe, rapid and accurate centering and ensuring subsequent safe and smooth drilling.
In order to achieve the purpose, the invention is realized by the following technical scheme:
A centering auxiliary device for a drill rod of an advanced drilling machine comprises a sleeve and a base, wherein the sleeve is mounted on a rotary blowout preventer at the tail part of a drill rod sleeve, the base is mounted at the drill rod tail of a rock drill, a reflecting plate is arranged on the side, close to the rotary blowout preventer, of the sleeve, a matt plate is arranged on the other side of the sleeve, a round hole is formed in the center of the matt plate, and a laser transmitter is arranged on the base; the centering adjustment process is completed through the light action among the laser emitter, the sub-light plate and the reflecting plate.
Furthermore, the round hole arranged at the sleeve connecting end is matched and connected with the cylinder arranged at the rotating blowout device connecting end, and the inner side of the round hole of the sleeve is provided with a sawtooth-shaped elastic device.
Further, the surface of the reflecting plate is coated with a reflecting coating which can be used for reflecting laser.
Further, the matt board is made of acrylic boards, the matt board has 50% of light transmittance, and the diameter of a circular hole formed in the center of the matt board is 10 mm.
Further, the laser emitter is fixed on the base through four socket head cap screws.
Furthermore, a circular hole structure arranged on the base is sleeved into a rock drill shank.
Compared with the prior art, the invention has the following advantages:
according to the auxiliary device for centering the drill rod of the advanced drilling machine, before the drill rod is installed, laser is used for adjusting centering, and detachable non-contact laser is used for replacing the drill rod to perform centering adjustment, so that safe, rapid and accurate hole alignment is realized; and then, installing a drill rod for trial drilling, and laying a foundation for subsequent safe and smooth drilling.
The invention ensures that the drill rod of the advanced drilling machine is concentric with the guide pipe as much as possible, and prevents the problems of orifice sealing failure and guide pipe damage caused by other rods.
