Pipeline outside ring seam automatic sand blasting device, the hunting range of more excellent is fork 22 is 100～300mm; The width of road wheel 35 is 30～80mm; The axial spacing of road wheel 35 on pipeline is 500～1000mm, and the hoop rectilineal interval is 300～600mm; The area coverage of dust cover 13 is 5 * 10 ⁴～7 * 10 ⁴Mm ²Spray gun 11 is 150～200mm apart from pipe surface; The screw thread of leading screw 25, nut 24 is T20 * 4～T30 * 6mm; The regulated quantity of regulating wheel 34 is 0～150mm.

Pipeline outside ring seam automatic sand blasting device, the hunting range of more excellent is fork 22 is 100～250mm; The width of road wheel 35 is 60mm; The axial spacing of road wheel 35 on pipeline is 700mm, and the hoop rectilineal interval is 500mm; The area coverage of dust cover 13 is 6 * 10 ⁴Mm ²Spray gun 11 is 160～180mm apart from pipe surface; The screw thread of leading screw 25, nut 24 is T24 * 5mm; The regulated quantity of regulating wheel 34 is 0～120mm.

The pipeline outside ring seam is as follows with the course of work of automatic sand blasting device: a rubber strip is wrapped on the pipeline 4 apart from the about 800mm of weld seam place, the pipeline outside ring seam is positioned on the pipeline 4 with the automatic sand blasting device, make sprocket wheel 32 be in rubber strip directly over, the vertical weld seams that point to of spray gun 11; Chain 33 passes through sprocket wheel 32, regulating wheel 34 on rubber strip, again with chain 33 two ends pintle hook locks; Depress regulating wheel 34, chain 33 is tightened; Blast tube, recovery tube are connected on respectively on spray gun 11, the suction nozzle 12; Regulate dust cover 13 and be close to tube wall, cover the sandblast district; Press " work " button, creep, swing, sandblast, recovery work simultaneously, inchworm motor 31 drives sprocket wheels 32, chain 33 and road wheel 35 and rotates, and drives whole device and creeps along pipeline 4; Swing motor 21 drives leading screws 25 rotations, and by nut 24 rotatablely moving of leading screw 25 is converted into rectilinear motion, and nut 24 moves on one side and when touching limit switch 26,

The commutation of swing motor 21, nut 24 are moved limit switch 26 to another side again until touching commutation, circulation and so forth; Fork 22 with nut 24 is connected as a single entity drives the spray gun assembly swing on roller 23; Suction nozzle 12 reclaims the sand grains in the dust cover 13, iron rust and dust.Spray gun assembly 1 moves on pipeline 4 with the zigzag track under the effect of wobble component 2 and walking assembly 3.Rust cleaning is unclamped regulating wheel 34 after finishing, and opens the pintle hook lock of chain 33, repeats said process, can descend the rust cleaning work of one weld seam.

The utility model beneficial effect compared with prior art is as follows:

1, the pipeline outside ring seam reduces the labour intensity of constructing with the automatic sand blasting device, increases safety of construction, and is simple in structure, easy to operate.

2, satisfy in the construction health, safety, environmental protection requirement.

3, rust cleaning quality height satisfies the anticorrosive construction requirement.
