Description

Pipeline butt welding positioning tool fixture
Technical field
The utility model is related to a kind of positioning tool fixture, more particularly to a kind of two pipeline butt welding when two pipelines are carried out pair Connect the tooling fixture of positioning.
Background technology
In pipe laying installation, the precision of the butt junction location of two connecting pipes can directly influence the butt welding of pipe welding port Quality, and the efficiency of pipeline docking construction.In constructing at the scene, the counterpart positioning for two pipelines being welded to connect is typically to use Manpower adds the instruments such as crowbar, and positioning is adjusted to two pipe joints, to reach the coincidence of two pipe centerlines, butt-joint clearance Uniform purpose.Wall thickness is larger when running into, and during the bigger pressure piping of every meter of substance, manpower adds the adjustment of the instruments such as crowbar Positioning can run into very big difficulty.Particularly run into that crossing ellipsization degree is overproof, and the situation that pipe wall thickness is larger, above-mentioned side can not be used Method corrects ovality, and now just deviation caused by crossing ellipsization degree need to be defined by pipe centerline, with docking on tube groove Lower four face allotments in left and right are uniform, and traditional docking calculation can not meet this requirement.
The content of the invention
The utility model provides a kind of pipeline butt welding positioning tool fixture, and it is tired to solve wall thickness pressure piping butt welding positioning Difficult technical problem.
The utility model is that solve above technical problem by the following technical programs:
A kind of pipeline butt welding positioning tool fixture, including the butt welding upper tube road mouth of pipe and the butt welding down tube road mouth of pipe, to burn-oning Left half clip and right half clip are provided with the pipeline mouth of pipe, left wedge-shaped location-plate is respectively arranged with the lateral surface of left half clip With preceding wedge-shaped location-plate, right wedge-shaped location-plate and rear wedge-shaped location-plate are respectively arranged with the lateral surface of right half clip, on a left side The lower end of wedge-shaped location-plate is fixedly installed left location nut, and prelocalization spiral shell is fixedly installed in the lower end of preceding wedge-shaped location-plate Mother, right location nut is fixedly installed in the lower end of right wedge-shaped location-plate, after being fixedly installed in the lower end of rear wedge-shaped location-plate Location nut, is bolted with left positioning adjustment bolt in left location nut, and the left front end movable top for positioning adjustment bolt is connected on pre- On the butt welding down tube road mouth of pipe below welding line, prelocalization adjustment bolt, prelocalization adjustment spiral shell are bolted with prelocalization nut The front end movable top of bolt is connected on the butt welding down tube road mouth of pipe below pre- welding line, and right positioning is bolted with right location nut and is adjusted Whole bolt, the front end movable top of right positioning adjustment bolt is connected on the butt welding down tube road mouth of pipe below pre- welding line, in rear positioning Adjustment bolt is positioned after being bolted with nut, the rear front end movable top for positioning adjustment bolt is connected under the butt welding below pre- welding line On the pipeline mouth of pipe.
Left wedge-shaped location-plate, preceding wedge-shaped location-plate, right wedge-shaped location-plate and rear wedge-shaped location-plate are in butt welding upper tube deferent On mouth at equal intervals radian set;Left half clip is respectively by left clamp connection bolt and right clamp connection spiral shell with right half clip Tether what is be connected together.
The utility model devises a simple and practical pipeline butt clamp, is positioned by the adjustment for adjusting four direction Bolt, quickly pipe welding port gap can be adjusted uniformly, it is easy to operate, improve butt welding quality.

Fig. 3 is the structural representation of wedge-shaped location-plate of the present utility model.
Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings:
A kind of pipeline butt welding positioning tool fixture, including the butt welding upper tube road mouth of pipe 1 and the butt welding down tube road mouth of pipe 2, in butt welding The clip 3 of a left side half and right half clip 4 are provided with the upper tube road mouth of pipe 1, left wedge shape is respectively arranged with the lateral surface of left half clip 3 Location-plate 7 and preceding wedge-shaped location-plate 8, are respectively arranged with right wedge-shaped location-plate 9 on the lateral surface of right half clip 4 and rear wedge shape is fixed Position plate 10, is fixedly installed left location nut 11 in the lower end of left wedge-shaped location-plate 7, is fixed in the lower end of preceding wedge-shaped location-plate 8 Prelocalization nut 13 is provided with, right location nut 15 is fixedly installed in the lower end of right wedge-shaped location-plate 9, in rear wedge-shaped location-plate 10 lower end is fixedly installed rear location nut 17, and left positioning adjustment bolt 12, left positioning are bolted with left location nut 11 The front end movable top of adjustment bolt 12 is connected on the butt welding down tube road mouth of pipe 2 of the pre- lower section of welding line 19, in prelocalization nut 13 Prelocalization adjustment bolt 14 is bolted with, the front end movable top of prelocalization adjustment bolt 14 is connected under the butt welding of the pre- lower section of welding line 19 On the pipeline mouth of pipe 2, right positioning adjustment bolt 16, the front end activity of right positioning adjustment bolt 16 are bolted with right location nut 15 Apical grafting positions adjustment bolt on the butt welding down tube road mouth of pipe 2 below pre- welding line 19 after being bolted with rear location nut 17 18, the rear front end movable top for positioning adjustment bolt 18 is connected on the butt welding down tube road mouth of pipe 2 of the pre- lower section of welding line 19.
