when the steel pipe 100 needs to be drilled, the base shaft 10 is firstly penetrated into a channel of the steel pipe 100, after the position of a joint 22 in the butt joint seat 20 is aligned with the position of the steel pipe 100 to be drilled, the lifting motor 12 in the base shaft 10 is started to push the steel pipe to lift and move outwards, in the process, the negative pressure cylinder 21 in the butt joint seat 20 extends out of the negative pressure pipe 13 in the base shaft 10, the negative pressure cylinder 21 is communicated with the negative pressure pipe 13, and then after the joint 22 of the butt joint seat 20 is tightly contacted with the inner wall of the steel pipe 100, the lifting motor 12 is stopped;

then, a hydraulic cylinder 40 arranged outside the steel pipe 100 is started to drive a drill point 42 to move downwards to be in contact with the outer wall of the steel pipe 100, meanwhile, a driving motor 41 is started to drive the drill point 42 to rotate to be used for drilling the position, needing to be drilled, of the steel pipe 100, after the drill point 42 completes drilling the steel pipe 100, the drill point 42 can be poked into a channel of the steel pipe 100, the drill point 42 penetrates into a connector 22 at the moment, so that the debris falls into the negative pressure cylinder 21 through the connector 22, the debris in the negative pressure cylinder 21 is sucked through negative pressure generated by a negative pressure pipe 13 in the base shaft 10, and the debris enters the negative pressure pipe 13 to be collected and discharged;

after the drill point 42 is separated from the steel pipe 100 through the hydraulic cylinder 40, the telescopic motor 31 of the machining seat 30 is started to drive the embedded body 32 to slide along the side sliding port 23 of the negative pressure cylinder 21 and enter the negative pressure cylinder 21, at the moment, the chip removal port 38 of the embedded body 32 is communicated with the negative pressure cylinder 21, then the rotary motor 35 and the telescopic electric pole 36 are started to enable the grinding head 37 to be in contact with the hole in the inner wall of the steel pipe 100, burrs in the hole are ground and removed, the ground chips fall into the opening 33 of the embedded body 32, and the chips in the opening 33 are sucked into the negative pressure pipe 13 through the chip removal port 38 through the negative pressure of the negative pressure cylinder 21 and are collected and discharged.

In the above steps, while the base shaft 10 penetrates the channel of the steel pipe 100, the steel pipe 100 penetrates the dust removal ring 70, and then when the hydraulic cylinder 40 drives the drill point 42 to move downwards, the steel pipe 100 contacts the outer wall of the steel pipe 100 after penetrating the through hole 71 of the dust removal ring 70, and then when the drill point 42 drills the steel pipe 100, the annular groove 72 of the dust removal ring 70 blocks the chips generated by drilling from splashing, and meanwhile, the dust suction pipe 73 below the annular groove 72 sucks the chips in the annular groove 72, so that the chips generated during drilling cannot splash to the peripheral equipment of the steel pipe 100.

Although the illustrative embodiments of the present invention have been described above to enable those skilled in the art to understand the present invention, the present invention is not limited to the scope of the embodiments, and it is apparent to those skilled in the art that all the inventive concepts using the present invention are protected as long as they can be changed within the spirit and scope of the present invention as defined and defined by the appended claims.
