Part 33a and the second connector 33b, adjusts centre distance between sand-blasting gun 35 (including the first pipette tips 35a and the second pipette tips 35b),
According to sandblasting machine to pipeline derusting by sandblasting width to required between sand-blasting gun (including the first pipette tips 35a and the second pipette tips 35b)
Centre distance is adjusted, to reach efficient derusting by sandblasting demand.
Adapt to different tube diameters：According to sandblasting pipeline different tube diameters sandblasting demand, adjust sand-blasting gun first pipette tips 35a and 35b
The final distance moving radially.Leading screw 215 is driven to rotate by rotating rotary handle 219, worm drive result makes spacing regulation
Block 29 is mobile in leading screw 215, and the final distance that sand-blasting gun (including the first pipette tips 35a and the second pipette tips 35b) is moved radially is entered
Row is spacing, makes sand-blasting gun (including the first pipette tips 35a and and the second pipette tips 35b) can just fit tube wall it is ensured that sandblasting works
Steel sand can not reveal at tube wall, meanwhile, sand-blasting gun (include the first pipette tips 35a and the second pipette tips 35b) and tube wall are in pipeline
Axial friction is moderate.
Control system is controlled to the source of the gas direction entering cylinder 28, and after sandblasting machine is in place, source of the gas connects pusher cylinder
28 piston cylinder moves to close to pipeline outer wall direction, and its result is：The slide block 210 being connected with cylinder 28 drives the amplitude of oscillation to adjust machine
Structure 3 moves together, until limited regulating block 29 mechanical position limitation of slide block 210.Now, sand-blasting gun (includes the first pipette tips 35a and the
Two pipette tips 35b) just laminating tube wall be it is ensured that the steel sand of sandblasting work can not be revealed at tube wall, meanwhile, sand-blasting gun (inclusion the
One pipette tips 35a and and the second pipette tips 35b) moderate in pipeline axial friction with tube wall.
After the completion of in place, control system sends action command to oscillating motor, and oscillating motor drives oscillation actuating mechanism to enter
Row swings, and oscillation actuating mechanism is connected with the pedestal 13 swinging mounting seat 1 in double end sand-blasting gun adjusting means.By linearly sliding
Dynamic bearing 11 slides on feed rod 214a and 214b, thus driving double end sand-blasting gun adjusting means to carry out swinging derusting by sandblasting work
Make.
After the completion of derusting by sandblasting work, control system is controlled to the source of the gas direction entering cylinder 28, and source of the gas is connected and pushed away
The piston cylinder of cylinder 28 of taking offence moves to away from pipeline outer wall direction, and its result is：The slide block 210 being connected with cylinder 28 drives the amplitude of oscillation
Governor motion 3 moves together, until cylinder 28 reaches end travel position, now, sand-blasting gun (includes the first pipette tips 35a and the
Two pipette tips 35b) away from pipeline outer wall, it is easy to the shift operation of abrasive blasting rust-cleaning machine.
