Before cleaning, the steel pipe 100 is greasy, and the steel pipe 100 is pushed by the existing guide wheel 60, so that the steel pipe 100 sometimes slips and the steel pipe 100 cannot be guided well. Therefore, the present application reforms the guide wheels 60 to divide the guide wheels 60 into two groups, and as shown in fig. 10, lifts one of the guide wheels 60 by the movable arm 64 so that the steel pipe 100 passes through the two groups of steel pipes 100

The two sets of guide wheels 60 press the steel pipe 100 one above the other, and after the movable arm 64 is fastened (the rotary joint of the movable arm 64 is fixed), the sufficient pressure between the guide wheels 60 and the steel pipe 100 can be maintained to push the steel pipe 100, and the steel pipe 100 with different sizes can be adapted by lifting the set of guide wheels 60. In addition, the guide strips 63 are arranged on the outer surfaces of the movable rollers 62, and when the movable rollers 62 push the steel pipe 100, the guide strips 63 made of the water absorbing material can absorb grease on the steel pipe 100, so that the steel pipe 100 is not easy to slip, the steel pipe 100 is guided, and the subsequent brushing efficiency is prevented from being influenced.

Example four:

an internal rotation brushing method is applied to an internal rotation brushing structure in the first embodiment or a pipe cleaning machine in the second embodiment or the third embodiment, and comprises the following steps:

when the steel pipe 100 needs to be brushed, the driving motor 11 in the outer body 10 is started to drive the driving gear 12 to rotate, and then the driven wheel 21 and the brushing shaft sleeve 20 connected with the driven wheel 21 are driven to rotate through the driving gear 12;

the embedded ring 31 of the washing ring 30 is driven to rotate while the brushing shaft sleeve 20 rotates, and the embedded ring 31 is rotatably connected with the water guide ring 32, so that the water guide ring 32 is kept still, water flow is introduced into the water guide cavity 34 of the water guide ring 32, so that the water flow enters an opening formed in the sealing ring 35 between the embedded ring 31 and the water guide ring 32 along the water guide cavity 34, the water flow enters the water spray holes 37 through the opening, and the water flow sprays water to two sides of the brushing cavity 22 in the brushing shaft sleeve 20 through the water spray holes 37;

then, the steel pipe 100 is pushed into the brushing cavity 22 of the brushing shaft sleeve 20, so that the steel pipe 100 is in contact with the brush 24, then the brush 24 rotates around the circumferential outer wall of the steel pipe 100 to brush under the driving of the rotation in the brushing shaft sleeve 20, meanwhile, the water spray holes 37 spray water flow to the brush 24 and the outer wall of the steel pipe 100, the brush 24 is washed, the cleanness of the brush 24 is kept, and the brush 24 has enough water flow to dissolve and wash attachments on the steel pipe 100 when the steel pipe 100 is brushed.

In the above steps, when the brush 24 contacts the steel pipe 100, the brush 24 is pressed to bend along the length direction of the steel pipe 100, and then the brush 24 and the steel pipe 100 are driven by the rotation of the brushing shaft sleeve 20 to rub each other, so that the movable ball 28 on the brush 24 rotates, and further the bending direction of the brush 24 is changed to be curved along the circumferential surface of the steel pipe 100, and finally, when the brush 24 brushes the steel pipe 100, the stress strength at the joint of the brush 24 is reduced.

Although the invention has been described with respect to illustrative embodiments thereof so that those skilled in the art can understand the invention, it is to be understood that the invention is not limited to the disclosed embodiments, but rather, is intended to cover all modifications and variations within the spirit and scope of the invention as defined and defined by the appended claims.
