Its purpose is in order to provide a simple structure, can avoid welding the pipeline under pressure weld bond positioner of frock on by weld workpiece. The utility model discloses pipeline under pressure weld bond positioner includes a pair of semicircle shaped plate, triangle ear and wedge angle iron, and a pair of semi -circular ring board can be in the same place through the bolt fastening, forms the ring form, and the triangle ear is provided with a plurality ofly, fixes on two semicircle shaped plates, along the ring periphery round evenly distributed that two semi -circular plate -types become, is provided with the groove that is used for squeezing into the wedge angle iron from one side on the triangle ear, the cutting has the wedge breach on the semi -circular ring board, and the triangle ear is fixed with the semicircle shaped plate on the wedge breach through the welding, semi -circular plate thickness is not less than pipeline under pressure thickness and is not less than 5mm.
Description
Technical field
The utility model relates to pipeline welding field, is specifically related to a kind of pressure pipeline weld bond positioner.
Background technology
In pressure pipeline installation process, weld bond place requires that unfitness of butt joint is not more than 10% of wall thickness, and is less than 2mm.When diameter of steel tube is larger, align with the artificial aligning that is difficult to, be also just difficult to ensure technological requirement.
In the past, operative employee welded several angle irons in the side of weld bond near weld bond place, squeezed into wedge shape angle iron at opposite side, and the inward flange by several wedge shape angle irons fixes two circular welded pieces.But this way has a defect, welding conditions sometimes requirement must not on welded piece striking and welding other irrelevant parts, especially pressure vessel or boiler tubing and special substance are as more must not arbitrarily welding tooling or other irrelevant parts on non-ferrous metal, otherwise can cause deterioration or the change of material.
Utility model content
The technical problems to be solved in the utility model is to provide the pressure pipeline weld bond positioner that a kind of structure is simple, can avoid welding tooling on welded part.
The utility model pressure pipeline weld bond positioner, comprise a pair semicircular plate, triangle ear and wedge shape angle iron, described a pair semi-round annular plate can be bolted on together, formed circular, described triangle ear is provided with multiple, be fixed on two semicircular plates, the annulus circle outer Monday formed along two semicircular plates is uniformly distributed, and described triangle ear is provided with the groove for squeezing into wedge shape angle iron from side.
The utility model pressure pipeline weld bond positioner, wherein said semi-round annular plate is cut with wedge-shaped indentation, and described triangle ear is fixed with semicircular plate by being welded in wedge-shaped indentation.
The utility model pressure pipeline weld bond positioner, wherein said semicircular plate thickness is not less than pressure pipeline thickness and is not less than 5mm.
The utility model pressure pipeline weld bond positioner difference from prior art is that this device of the utility model pressure pipeline weld bond positioner uses two semi-round annular plate to be bolted on the pipe welding port place needing welding, with wedge shape angle iron from triangle ear through evenly squeezing into, the most advanced and sophisticated position of wedge shape angle iron is made to be pressed on another workpiece, by beating tighter and tighter in wedge shape angle iron, two workpiece are firmly fixed together, because wedge shape angle iron is uniformly distributed along the circumference, just can workpiece to be fixed in one in the heart after evenly squeezing into, unfitness of butt joint can meet technological requirement completely.
The utility model pressure pipeline weld bond positioning device structure is simple, accurately can realize location, also avoid and weld other frocks on welded part.
Below in conjunction with accompanying drawing, pressure pipeline weld bond positioner of the present utility model is described further.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model pressure pipeline weld bond positioner;
Fig. 2 is the using state figure of the utility model pressure pipeline weld bond positioner.
Detailed description of the invention
As shown in Figure 1, the utility model pressure pipeline weld bond positioner comprises a pair semicircular plate 1, triangle ear 2 and wedge shape angle iron 3, two semi-round annular plate can be fixed together by bolt 4, formed circular, triangle ear 2 is provided with multiple, semi-round annular plate cuts out wedge-shaped indentation, triangle ear 2 is fixed with semicircular plate 1 by being welded in wedge-shaped indentation, the annulus circle outer Monday that triangle ear 2 is formed along two semicircular plates is uniformly distributed, and triangle ear 2 is provided with the groove for squeezing into wedge shape angle iron 3 from side.Semicircular plate thickness is not less than pressure pipeline thickness and is not less than 5mm.
According to the size of caliber, the number of fixed triangle ear is different with the size of caliber, below Φ 57mm, two; Φ 76mm ~ Φ 159mm can with three; Φ 194mm ~ Φ 325mm with four, can be uniformly distributed along the circumference, and in a word, diameter is larger, and fixed triangle ear used is more; Large-diameter pipeline or equipment, be advisable with the spacing 150 ~ 200mm of triangle ear.
As shown in Figure 2, during use, two semi-round annular plate 1 are fixed on by bolt 4 the duct work weld bond place that needs welding, distance pipe welding port edge 20 ~ 30mm, with wedge shape angle iron 3 from side triangle ear 2 through evenly squeezing into, the most advanced and sophisticated adjacent margins of wedge shape angle iron 3 is made to be pressed on another workpiece 5, beat tighter and tighter by wedge shape angle iron, just two workpiece firmly can be fixed together, because wedge shape angle iron is uniformly distributed along the circumference, just can workpiece to be fixed in one in the heart after evenly squeezing into, unfitness of butt joint can meet technological requirement completely, realizes location.
This device can avoid welding tooling on welded part, this frock is fixed by bolts on the workpiece of side, in fixed triangle ear, squeeze into wedge shape angle iron, as long as frock intensity is enough indeformable, the inward flange of several wedge shape angle irons just can be leaned on to fix two welded pieces.
Above-described embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
