Abstract
Pipe welding fixing device is used in butt welding of pipe to pipe to ensure that the pipeline will not be misplaced in welding. The top half of the arc pipe and the bottom half of the arc pipe butt form a round pipe. A top dormer is open in the wall of the top half of the arc pipe, and a bottom dormer is open in the wall of the bottom half of the arc pipe. A top leading panel is welded on the outer wall of the edge of the top half of the arc pipe, and a bottom leading panel is welded on the outer wall of the edge of the bottom half of the arc pipe. The top and bottom leading panels are rectangular iron panels. A top bolt hole is arranged at the top leading panel, and a bottom hole is arranged at the bottom leading panel. The top leading panel is opposed to the bottom leading panel. Bolts are fixed in the top and bottom bolt holes. The effect is that both ends of the pipes are opposed to each other, caught in the pipe welding fixture. Ends of the pipes will be welded opposed to each other accurately, and dislocation of pipe welding is limited within an allowable area to improve the welding quality.
Description
Technical field
The utility model relates to oil-gas field surface engineering construction technique field, and pipeline butt joint welding in particularly a kind of surface duct work progress is a kind of pipeline welding fixture that can not influence welding quality when guaranteeing pipeline welding because of dislocation.
Background technology
At present, surface duct welding general employing mechanical hoisting or artificial lifting are the pipe ends alignment of needs welding.Because pipeline quality is very big, when butt joint, be difficult to move, be difficult to guarantee that butt joint is neat, when welding the docking port dislocation bigger, influence welding quality, cause pipeline to destroy too early, influence ordinary production, even may jeopardize personal safety.For the error that reduces to produce in the welding process, design a kind of device and the pipeline at docking port two ends is fixed on just seems necessary in the qualified error range by force.
The utility model content
The purpose of this utility model is: a kind of pipeline welding fixture is provided, and soldered pipe ends is relative, be clipped in the pipeline welding fixture, and adjust the screw spacing, the dislocation of pipeline docking site is reduced gradually until reaching meet welding requirements.
The technical solution adopted in the utility model is: the pipeline welding fixture, mainly form by first arc tube, last corbel back slab, upper bolt hole, second arc tube, following bolt hole, following corbel back slab and bolt, it is characterized in that: first arc tube is relative with second arc tube to become a round tube, have the skylight on the wall of first arc tube, on the wall of second arc tube, having skylight down; On the edge of first arc tube outer wall, be welded with corbel back slab, on the edge of second arc tube outer wall, be welded with corbel back slab down.Last corbel back slab and following corbel back slab are rectangle iron plates; On last corbel back slab upper bolt hole is arranged, on the corbel back slab following bolt hole is being arranged down, last corbel back slab is relative with following corbel back slab, is fixed with bolt in upper bolt hole and following bolt hole.Can be fixed on two pipe ends of needs welding in the pipeline welding fixture.Bolt on then, adjust the error at two pipe joint places gradually, till satisfying welding requirements.Two last skylight of aligning, place and following skylights that pipe end need weld.By last skylight and following skylight pipeline is welded.Unclamp screw rotating pipe weld fixture apparatus, and then bolt on, do not have the position of welding to weld by last skylight and following skylight to pipeline, until finishing pipeline welding.
For first arc tube and second arc tube are linked together, in an opposite end of first arc tube and second arc tube bearing pin is arranged, bearing pin links together an opposite end of first arc tube and second arc tube.First arc tube 1 can relatively rotate by bearing pin with second arc tube like this, realizes that first arc tube and second arc tube open or close.
After described first arc tube was relative with second arc tube, its internal diameter was identical with soldered outer diameter tube.First arc tube and second arc tube adopt carbon steel or stainless steel to make.
The beneficial effects of the utility model: the utility model pipeline welding fixture, soldered pipe ends is relative, be clipped in the pipeline welding fixture.The pipeline welding end is accurately relative, and pipeline welding position offset error limits in allowed limits, can improve welding quality.

Fig. 2 is the utility model pipeline welding fixture closed condition structural representation.
Among the figure, first arc tube of 1-, the last skylight of 2-, the last corbel back slab of 3-, 4-upper bolt hole, second arc tube of 5-, bolt hole under the 6-, corbel back slab under the 7-, skylight under the 8-, 9-bearing pin.
The specific embodiment
Embodiment 1: be applicable to that with one external diameter is that the pipeline welding fixture of the pipeline butt welding of 500mm is an example, is described in further detail the utility model.
Consult Fig. 1.The utility model pipeline welding fixture is made up of first arc tube 1, last corbel back slab 3, upper bolt hole 4, second arc tube 5, following bolt hole 6, following corbel back slab 7, bearing pin 9 and bolt.First arc tube 1 and second arc tube 5 be relative round tube that to become an internal diameter be 500mm, length is 1000mm.Having a length on the wall of first arc tube 1 is 500mm, and arc length is the last skylight 2 of 500mm, and opening one on the wall of second arc tube 5, length is arranged is 500mm, and arc length is the following skylight 8 of 500mm.
On an edge outer wall of first arc tube 1, be welded with corbel back slab 3, on an edge outer wall of second arc tube 5, be welded with corbel back slab 7 down.Last corbel back slab 3 and following corbel back slab 7 are rectangle iron plates; Two upper bolt holes 4 are arranged on last corbel back slab 3, down on the corbel back slab 7 two following bolts hole 6 are being arranged, last corbel back slab 3 is relative with following corbel back slab 7, is fixed with bolt in upper bolt hole 4 and following bolt hole 6.
There is a bearing pin 9 another opposite end at first arc tube 1 and second arc tube 5, and bearing pin 9 links together an opposite end of first arc tube 1 and second arc tube 5.
