[0002] A pipeline refers to a device formed by connecting pipes, pipe connectors, valves, etc. for transporting gases, liquids, or fluids with solid particles. Usually, after the fluid is pressurized by a blower, compressor, pump, boiler, etc., it flows from the high-pressure part of the pipeline to the low-pressure part, or it can also be transported by the pressure or gravity of the fluid itself. Pipelines have a wide range of uses and are mainly used in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations.

[0003] These pipelines are formed by welding a series of standard pipelines. A series of preparatory processes are required during welding, and grinding the paint and rust on the inner and outer walls of the pipeline ports is a very important process.

[0004] Currently, pipeline rust removal mainly includes laser rust removal, shot blasting machine rust removal, and grinder rust removal. The first two rust removal methods are not suitable for construction site operations. When using a grinder to remove rust from large-diameter pipelines, it is impossible to remove rust from the inner side of the welding parts of the pipeline or pipe fittings, the effect is not ideal, which affects the welding quality, and at the same time, the efficiency is low and it causes great harm to human health.

The grinding unit includes an "L"-shaped fixed rod 1. A sliding rod 2 is slidably arranged on the vertical part of the fixed rod 1, and the vertical part of the sliding rod 2 slides within the vertical part of the fixed rod 1. One driving gear 3 is rotatably arranged at one end of the horizontal parts of the fixed rod 1 and the sliding rod 2 respectively. A rust removal roller 4 is coaxially fixed on the side of the driving gear 3 facing away from the fixed rod 1;

[0033] One adjusting rod 5 is rotatably arranged on the horizontal parts of the fixed rod 1 and the sliding rod 2 respectively. The other end of the adjusting rod 5 is the traveling unit, and a fastening clip 6 is used for fixing the state of the traveling unit.

[0034] One connecting rod 7 is rotatably arranged on each driving gear 3. One ends of the two connecting rods 7 are rotatably connected to each other. An intermediate gear 8 is rotatably arranged at the connecting end of the two connecting rods 7. The intermediate gear 8 meshes with the two driving gears 3 respectively;

[0035] A grinding motor 9 is fixedly arranged on the horizontal part of the sliding rod 2, and the motor shaft of the grinding motor 9 is coaxially fixed with the driving gear 3 rotatably arranged on the sliding rod 2.

[0036] The traveling unit includes two support rods. Each support rod is fixedly connected to one end of one of the adjusting rods 5 respectively. A traveling motor 11 is fixedly arranged at one end of each support rod away from the adjusting rod 5. A traveling roller 12 is coaxially fixed on the motor shaft of the traveling motor 11 respectively.

[0037] The fastening clip 6 includes two clamping arms 13 whose middles are rotatably connected to each other. One end of each clamping arm 13 is fixed to one end of the adjusting rod 5, and a torsion spring is arranged on the rotating shaft of the two clamping arms 13.

[0038] The adjusting rod 5 includes two rectangular long rods. One ends of the two rectangular long rods are rotatably connected to each other through a rotating shaft 17. The rotating shaft 17 can ensure that when the clamping arm 13 is moved, the adjusting rod 5 will not affect the use of the fastening clip 6.

[0039] The outside of the rust removal roller 4 is detachably covered with rust removal steel wires 14.

[0042] When the present invention is in use, loosen the locking bolt 15, and the position of the sliding rod 2 can be dragged back and forth. The axle distance between the two driving gears 3 changes. Adjust the center axle distance between the two wire rust-removing rollers to the wall thickness length of the straight pipe section through the connecting rod 7. Then rotate the locking bolt 15 to fix it. Then press one end of the clamping arm 13 to make its torsion spring contract and coil. The two support rods expand outwards so that the two traveling rollers 12 can be respectively located on both sides of the pipe wall. Loosen the clamping arm 13, and the traveling rollers 12 will apply pressure and clamp on the pipe walls of the straight pipe 19 and the bent pipe 20. Connect the power supply to this device through the power cord, start the grinding motor 9 and the traveling motor 11 respectively. The rust-removing rollers 4 and the traveling rollers 12 rotate respectively, and this device starts automatic rust removal.

[0043] When there is no pipe rack at the construction site, just place the straight pipe 19 on the ground 21 and place a support 22 under one end of the straight pipe 19 to be polished to make the polished end of the straight pipe 19 leave the ground, then the polishing of the pipe can be completed without being affected by the construction environment.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
