The connecting frame 10 is provided with four and is evenly fixed between the two end blocks 9. The connecting frame 10 is connected to a rust removal block 11 through an adjustment mechanism. A rust removal brush 12 is provided on the inner end of the rust removal block 11. A plurality of dust suction ports 13 are provided on the inner side wall of the rust removal block 11. The left end of the rust removal block 11 is connected to an extension The telescopic hose 7 is connected to the multiple dust suction ports 13 on the same rust removal block 11. The dust suction device 6 is installed at the top of the base 1 and is located on the left side of the bracket body 2 on the left. The four telescopic hoses 7 pass through the bracket body 2 on the left and are connected to the dust suction device 6. The two end blocks 9 and the bracket body 2 on the right are both provided with circular hollows and the axes coincide. A rotating mechanism for driving the steel pipe to rotate is provided on the base 1. The rotating mechanism includes a transmission frame 14. A telescopic cylinder 15 is installed downward on the top of the transmission frame 14. The output end of the telescopic cylinder 15 passes downward through the transmission frame 14 and is fixed with a lifting block 16. The lifting block 16 is rotatably connected to a transmission wheel 17. A second motor 18 is installed on the lifting block 16. The output end of the second motor 18 is fixed to the transmission wheel 17. Two rollers 19 are symmetrically provided on the transmission frame 14 directly below the transmission wheel 17. The rollers 19 are rotatably connected to the transmission frame 14. A support shaft 20 is rotatably connected to the bracket body 2 on the left side, and the axis of the support shaft 20 coincides with the circular hollow axis on the end block 9.

[0025] When the device is in use, first pass the building steel pipe through the circular hollow part of the end block 9 and the bracket body 2, and place the steel pipe in the middle of the rust removal component 8 so that it contacts the rust removal brush 12. The support shaft 20 is inserted into one end of the steel pipe and contacts it. At this time, the steel pipe is placed on the two rollers 19, and the telescopic cylinder 15 is started to drive the lifting block 16, the second motor 18 and the transmission wheel 17 to move downward until the transmission wheel 17 contacts the steel pipe. The second motor 18 is started to drive the transmission wheel 17 to rotate, and the transmission wheel 17 contacts the steel pipe. The steel pipe is driven to rotate by friction, and when the steel pipe rotates, it moves relative to the rust removal brush 12, so that the rust removal brush 12 rubs against the surface of the steel pipe, and the rust falls off the steel pipe. At the same time, the dust suction device 6 is started, and the dust suction device 6 absorbs the rust that has fallen off the steel pipe at the dust suction port 13 through the telescopic hose 7. The first motor 3 is started to drive the reciprocating screw rod 4 to rotate, and the upper end block 9 of the threaded reciprocating screw rod 4 moves back and forth along the guide rod 5, so that the rust removal component 8 moves back and forth, and the rust removal component 8 fully removes rust from the steel pipe.

[0026] In actual use, it was found that after long-term use, the rust removal brush 12 would produce friction loss, which would cause the rust removal brush 12 to be unable to contact the steel pipe. In order to solve the above problem, in this embodiment, the adjustment mechanism includes a sliding groove 21, and the sliding groove 21 is provided with a plurality of evenly opened on the connecting frame 10. The rust removal block 11 is adapted to and slidably connected to the sliding groove 21, and an adjusting threaded rod 22 is threadedly connected to the connecting frame 10, and one end of the adjusting threaded rod 22 is rotatably connected to the rust removal block 11.

[0027] It is found in actual use that the steel pipe may contact the end block 9 and cause wear. In order to avoid the above problem, in this embodiment, a plurality of rolling balls 23 are rotatably connected to the inner wall of the circular hollow position of the end block 9.

[0028] In actual use, it is found that some debris will fall when the steel pipe is derusted, which is not easy to clean. In order to solve the above problem, in this embodiment, the top of the base 1 is located directly below the rust removal component 8 and is slidably connected to a collection tank 24.

[0029] It was found in actual use that the device may slip during operation. In order to avoid the above problem, in this embodiment, a plurality of bracket feet 25 are installed at the bottom end of the base 1, and the bottom ends of the bracket feet are provided with anti-slip grooves.
