Description

The steel pipe inside and outside wall is thrown the shot peening device automatically

The utility model relates to a kind of anticorrosion rust cleaning technology, and especially the steel pipe inside and outside wall is thrown the shot peening device automatically.

At present technique known is: the derusting by sandblasting that the metal surface preliminary treatment is adopted is the simple manual labor based on manually-operated, by manually pickaback the sand-blasting gun head facing to scope of operation work, and then by labor cleaning's blown sands, the negative effect of these technology is conspicuous, exists problems such as the working environment of workers is poor, serious harm health, labor strength height, efficiency is low, the surface quality roughness is inhomogeneous.

The purpose of this utility model provides a kind of brand-new steel pipe inside and outside wall and throws the shot peening device automatically, utilize intelligent automation control (automatically the turnover pipe, automatically tube, sandblast automatically, sand removal automatically, carry sand automatically), not only greatly improved efficiency, also greatly reduced simultaneously people's labour intensity, because I and II dedusting control, create clean working environment, guaranteed people's physical and mental health.

The purpose of this utility model is achieved in that it is by being loaded with synchronous fortune pipe dolly A and B, closed sand blasting room, flower stand cantilever and inlet flange, inwall outer wall sand-blasting gun, inside pipe wall blast valve, the go-cart of strike-ofing of rolling tire, carrying sand machine, I and II dedusting, air compression system, inwall, outer wall pressure sand jar, distribution control centre etc. and partly form.The trolley travelling track is installed on the concrete basis, dolly A, B place in orbit synchronously, move toward anti-during work, vehicle-mountedly roll tire A and B is placed on respectively on synchronous dolly A and the B, the spacing fine setting is installed in vehicle-mounted rolling on the tire A, spacing coarse adjustment two ends are fixed on synchronous dolly A and the B, utilize big pipe box tubule to reach the adjustment purpose; Coarse adjustment link supports wheel is fixed on the middle part of coarse adjustment; Inlet flange is fixed on the flower stand suspended wall, the flower stand suspended wall is fixed on the suspended wall column, the suspended wall column is embedded in the concrete, inwall gun stand, inwall blowhead all are fixed on the flower stand suspended wall, the inwall sand pocket is fixed on the suspended wall, the inwall spray gun is fixed on the inwall gun stand, and the outer wall spray gun is fixed on the outer wall gun stand, and the outer wall gun stand is fixed on the support on sand blasting room doorway; Strike-off the go-cart track near synchronous trolley track inner underside, and be fixed on the concrete basis, the go-cart of strike-ofing moves on the go-cart track of strike-ofing; Inside and outside wall pressure sand jar links to each other with the sealing sand blasting room by inside and outside wall sand pocket passage, and institute is dynamic to wait electrical equipment to guide distribution center into by power cable and control cable with control.

Automatically round-trip synchronization dolly A, B and the vehicle-mounted tire that rolls are responsible for acknowledgement of consignment and are rotated steel pipe, and the adjustable passive tire that rolls is adjusted fine setting, coarse adjustment to be fit to the length of steel pipe to be fit to the diameter of steel pipe; Dolly link supports wheel can prevent that the connecting rod sag is excessive; Detachable inlet flange is to be fit to the diameter of steel pipe; Closed sand blasting room can prevent the pollution of the environment, and adjustable inside and outside wall gun stand is to be fit to the diameter of steel pipe, and adjustable flower stand suspended wall is fixed with inwall gun stand, sand pocket and the head of blowing sand simultaneously to be fit to the diameter of steel pipe on the suspended wall; Cleaning collection sand is responsible in the automatic reciprocating go-cart of strike-ofing; Dedusting fan provides exhausting wind-force; Cyclone dust collectors are responsible for primary dust removing, and the spray atomizing is as two-stage dust removal; Carry the sand machine and be responsible for carrying sand; Distribution control centre provides power and control for all consumers; Air compressor machine provides compressed air; The pressure sand jar provides the pressure sand gas mixture for lance head.

In when operation, at first adjust, the one, according to steel pipe length to be eliminated rust, adjust spacing fine setting and spacing coarse adjustment connecting rod, make pipe range and dolly A, B and vehicle-mounted to roll tire supporting; The 2nd, adjust according to diameter of steel tube to be eliminated rust: the distance and the angle of position, inwall outer wall sand-blasting gun and inside and outside tube wall of rolling height, the inwall blowhead of size, the flower stand cantilever of width, the inlet flange of tire; The 3rd, the speed of service of adjusting synchronous dolly A, B makes the rust cleaning effect reach specification requirement; The 4th, the speed of adjusting the go-cart of strike-ofing makes it supporting with the sand amount.Above-mentioned adjustment finishes just can carry out derusting by sandblasting, and its rust cleaning process is: the one, start ancillary equipment such as air compressor machine, primary dust removing blower fan, two-stage dust removal water pump, pressure sand jar power; The 2nd, start the synchronous dolly that is loaded with steel pipe, its speed is mixed up by frequency converter; The 3rd, start the vehicle-mounted tire (but forward and backward control) that rolls; The 4th, when dolly enters sand blasting room, remind automatically to start the inside and outside wall sand-blasting gun; The 5th, start inwall blowhead (opening the source of the gas valve); The 6th, start the go-cart of strike-ofing, its speed is mixed up by frequency converter; The 7th, start the sand machine of carrying.Synchronously trolley travelling is controlled it by travel switch and is returned automatically to the sand blasting room end, is back to be fit to the lifting position and to stop automatically, thereby finishes the rust cleaning process of a steel pipe.Strike-off go-cart with automatic reciprocating work constantly, constantly push collect the sand in the collection sand road to sandpit, sand is proposed recycling by carrying the sand machine.

Because adopt such scheme, anticorrosion rust cleaning even surface roughness is good.
