Description
Technical field
The invention belongs to pipeline internal corrosion patch technology fields, and in particular to sand blasting unit in a kind of pipeline-weld, mainly
At pipeline-weld, blasting treatment is carried out to face of weld inside pipeline, is prepared for interior anti-corrosion.
Background technique
Now, pipeline becomes oil and gas industry as a kind of economic, efficient and safe material mode of movement
Lifeline, therefore more stringent requirements are proposed to the integrality of pipeline corrosion protection layer, especially pipeline internal corrosion layer and welded seam area
Inner surface erosion resistant coating, but the method for all using wire brush to polish for the pre-treatment of weld seam inner surface now, there is polishing
Unevenly, the disadvantages of technical grade Sa2.5 (40~100 μm of anchor line) is not achieved in surface roughness, polishing dust drifts.
Summary of the invention
In order to overcome the shortcomings of above-mentioned technology, the purpose of the present invention is to provide sand blasting unit in a kind of pipeline-weld, tools
Have the characteristics that scientific and reasonable, controllable precise, manipulation are convenient.
To achieve the goals above, the technical solution of the present invention is as follows: sand blasting unit in a kind of pipeline-weld, includes sandblasting
Vehicle and recovery vehicle, the both ends of sandblasting vehicle are equipped with air bag, and the edge of air bag is equipped with support wheel group, and sandblasting vehicle inside center is equipped with sandblasting
Disk, the two sides of sandblasting disk are respectively equipped with small flexible protective cover and shell, and the rear end of shell is equipped with protective cover flexible greatly, sandblasting vehicle
Front end is equipped with front cover shell, is equipped with camera, connection seat, power outlet and data socket on front cover shell, the bottom of recovery vehicle is set
There are blower, feed bin and recover.
Air bag inflation/deflation simultaneously.
The support wheel group has six groups.
The revolving speed of the sandblasting disk is 20000rpm.
Beneficial effects of the present invention: sandblasting disk is closed by two air bags, prevents sand material and dust recycling；Camera can
To guarantee that butt welding is sewn on optimum position processing to weld seam precise positioning；Using high speed sandblasting disk, guarantee sand stockline speed, it can be with
Weld seam and two side areas are uniformly hit.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is arrangement schematic diagram of the sandblasting vehicle of the present invention at pipeline internal weld seams.
Fig. 3 is sandblasting Chinese herbaceous peony end view of the present invention.
Specific embodiment
Structural principle and working principle of the invention are described further with reference to the accompanying drawing.
Referring to figure 1, figure 2 and figure 3, sand blasting unit in a kind of pipeline-weld, includes sandblasting vehicle and recovery vehicle, sandblasting vehicle
Both ends are equipped with air bag (2,3), and the edge of air bag (2,3) is equipped with support wheel group 7, and sandblasting vehicle inside center is equipped with sandblasting disk 1, sandblasting
The two sides of disk 1 are respectively equipped with small flexible protective cover 12 and shell 14, and the rear end of shell 14 is equipped with protective cover 15 flexible greatly, sandblasting vehicle
Front end be equipped with front cover shell 9, camera 8, connection seat 19, power outlet 17 and data socket 18 are installed on front cover shell 9, recycled
The bottom of vehicle is equipped with blower 4, feed bin 5 and recover 6.
The air bag 2 and 3 inflation/deflation simultaneously.
The support wheel group 7 has six groups.
The revolving speed of the sandblasting disk 1 is 20000rpm.
Functional parameter of the invention is as follows:
The technical principle of the covering device can be adapted for DN300 millimeters or more of pipeline；The revolving speed of sandblasting disk is
20000rpm；Sand material is 35 times Ke Xunhuanliyong in feed bin；Inner surface of pipeline after blasting treatment can reach technical grade Sa2.5 (gold
Belong to nearly white grade), depth of abrasion pattern is 52 μm~95 μm.
The working principle of the invention:
Interior sand blasting unit enters pipeline 11, by 8 tack weld 13 of camera, sandblasting disk 1 is made to be directed at the center of weld seam 13,
Air bag (2,3) is inflated simultaneously, the inner wall area of 13 liang of side ducts 11 of weld seam is closed, 1 high speed rotation of sandblasting disk is (in Fig. 1 at this time
Curved arrow), recovery vehicle upper fan 4 starts, and the sand material in feed bin 5 is sent into sandblasting disk 1, sandblasting disk 1 is by sand material high speed peening
To weld seam 13 and two side areas 16, flexible protective cover 12 small at the same time, sandblasting disk 1, shell 14 and protective cover 15 flexible greatly are whole
Body does the reciprocating motion (four-headed arrow in Fig. 2) centered on weld seam 13, and to the end of sandblasting, air bag (2,3) is deflated simultaneously, a whole set of
Device moves ahead (arrow in Fig. 1), while recover 6 starts, and all sand material and dust are recovered to feed bin 5.
