Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

By figure 1 to 3, the utility model discloses a horizontally dull and stereotyped 1, wheel 2 is installed to dull and stereotyped 1 below, an annular cover 3 is all installed at both ends about dull and stereotyped 1, wheel 2 can drive dull and stereotyped 1 and the 3 side-to-side motion of annular cover, 3 coaxial and the axis of two annular covers is along controlling the direction, two annular covers 3 can the antiport, equal circumference equipartition has a plurality of radial bolts 4 on every annular cover 3's the lateral wall, bolt 4's head all stretches out annular cover 3 outer and every bolt 4's head and all installs a abrasive disc 5, through the distribution circle diameter of a plurality of abrasive discs 5 on the adjustable same annular cover 3 of adjusting bolt 4.

The grinding sheet 5 is arc-shaped and has a convex surface facing outwards, and the arc-shaped is coaxial with the annular sleeve 3.

The outer end of each bolt 4 is coaxially fixed with a guide pillar 6, the inner side of the grinding disc 5 is connected with a sleeve 7, the sleeve 7 is sleeved on the guide pillar 6 in a sliding mode and can rotate relative to the guide pillar 6, and a pressure spring 8 is installed between the grinding disc 5 and the outer end of the guide pillar 6.

An annular groove 9 is formed in the outer wall of the guide post 6, a radial screw 10 is installed on the side wall of the sleeve 7, the inner end of the screw 10 extends into the annular groove 9, and the sleeve 7 can be axially limited through the screw 10 and the annular groove 9.

Each annular sleeve 3 is coaxially and fixedly connected with a first gear 11, each first gear 11 is meshed with a second gear 12, each second gear 12 is driven by a grinding motor, and the rotation directions of the two grinding motors are opposite; the two grinding motors drive the annular sleeves 3 to rotate through the first gear 11 and the second gear 12 of the same group respectively, so that the two annular sleeves 3 are opposite in rotation direction.

A third gear 13 is fixed on the wheel axle of one group of wheels 2, a fourth gear 14 is meshed above the third gear 13, and the fourth gear 14 is driven by a walking motor so as to drive the wheels 2 to walk; of course, the power of one of the grinding motors can also be transmitted to the wheels 2 by reversing through bevel gears.

The mandrel of the annular sleeve 3 at the right end is of a hollow structure, and power lines of the three motors penetrate out of the mandrel and are connected with a power supply; this ensures that the power cord does not interfere with the rotation of the annular sleeve 3.

Each wheel 2 is connected with the wheel shaft in a sliding way and can be fixed through a locking screw 10, so that the span of the wheel 2 can be adjusted to adapt to pipelines with different pipe diameters.

The utility model discloses when specifically using, at first adjust a plurality of bolts 4, the distribution circle diameter of a plurality of abrasive discs 5 on each ring cover 3 all equals or slightly is greater than the internal diameter of the pipeline of waiting to derust, abrasive disc 5 and bolt 4's swing joint can make abrasive disc 5 not rotate along with bolt 4, then place this device in the pipeline, then a plurality of abrasive discs 5 press the pipeline inner wall under the effect of pressure spring 8, then the switch of closed three motor starts three motor, the motor of two ring covers 3 drives two ring covers 3 counter-rotation through first gear 11 and second gear 12, a plurality of abrasive discs 5 on two ring covers 3 polish the rust cleaning to the pipeline inner wall; the two annular sleeves 3 are opposite in rotation direction, so that the torque borne by the flat plate 1 is balanced, and the flat plate cannot twist back and forth; when two annular cover 3 rotated, the motor of wheel 2 drove wheel 2 through third gear 13 and fourth gear 14 and rotates and make this device advance along the pipeline, and the inner wall that will really manage is polished and is accomplished, then the motor of reverse start wheel 2, make this device withdraw from the pipeline can.

The utility model has the advantages that the stress of the whole device is balanced by the reverse rotation of the two annular sleeves 3, and the device can not be twisted in the polishing process, so that the relative motion between the abrasive disc 5 and the inner wall of the pipeline is ensured, the rust removal work is smoothly carried out, and meanwhile, the two groups of abrasive discs 5 on the two annular sleeves 3 carry out forward and reverse two times of polishing on the inner wall of the pipeline, so that the rust removal is more comprehensive, and the rust removal effect is better; in addition, the device can remove rust on the inner walls of pipelines with different pipe diameters, and has strong adaptability.
