Abstract
The utility model discloses an opening-to-opening centralizer for welding of pipelines, which comprises a handle, a screw rod, a bulb, an upper support, bolts, slips, a ball seat, a pull ring and a lower support. The opening-to-opening centralizer for welding of the pipelines is characterized in that: the upper support thereof is oblong; two V-shaped hanging slots are respectively formed on two ends; a threaded hole is formed in the centre; the handle is installed at the upper end of the screw rod; the bulb is at the lower end of the screw rod; the screw rod is screwed into the threaded hole in the centre of the upper support; the slips clamp the bulb and are connected with the ball seat by four bolts; an oblong hollow groove is arranged in the centre of the lower support which is an omega-shaped structure so as to reduce the weight of the lower support; hinging holes are arranged at the lower parts of the two ends; the hinging holes are connected with the oblong pull ring; and the upper part of the pull ring is hung in the hanging slot of the upper support. The opening-to-opening centralizer for welding of the pipelines is novel in design, easy to manufacture, low-cost, convenient for operation, time-saving, force-saving, safe, reliable, and capable of implementing welding and location of the pipelines, aligning the openings quickly, satisfying the construction demand of the site pipelines, and increasing the construction quality and the economic benefit.
Description
Technical field
The utility model relates to the pipeline construction weld bond and aligns specific purpose tool, particularly is a kind of pipeline welding counterpart centralizer.
Background technology
When the replacing of carrying out pipeline or new tubing, pipeline joins end to end at present, and weld bond is a lot.Because these operations are all open-air in the Gobi desert, the lofty injustice in job site, the port to be welded of two pipelines can not level, vertically over against.For two pipelines that caliber is identical, make the mouth of pipe align welding, we must take the pipeline bed hedgehopping that the position is relatively low, and the way that perhaps that the position is higher relatively pipeline reduces makes the pipe end alignment.This has just increased the construction working amount, has also increased labor strength, has prolonged the engineering time.When welding, also need manual work to set upright sometimes and align weld bond, colored both hands or the clothing that also injures the personnel of setting upright easily of weldering that strong electro-welding arc is also burnt easily and set upright personnel's eyes, descends slowly and lightly during welding.Thereby prior art can not solve the problems of the technologies described above.
Summary of the invention
The purpose of the utility model is exactly to above-mentioned weak point, has designed a kind of pipeline welding counterpart centralizer.
Above-mentioned purpose is realized by following technical proposals.
The utility model comprises: handle, leading screw, bulb, upward support, bolt, slips, ball seat, draw ring, support down.Be supported for rectangular build on it, respectively be provided with " V " type hanging groove above the two ends, the center is provided with screwed hole; Handle is installed in the upper end of leading screw; Bulb is positioned at the lower end of leading screw, and screwed hole screws in leading screw from last centre of support, and slips blocks bulb and by four bolts slips connected with ball seat; The following centre of support of " Ω " type structure is provided with the rectangle groove, and to alleviate the weight that supports down, the bottom, two ends is provided with fraising, and fraising is connecting the rectangle draw ring, and draw ring top hangs in the hanging groove that supports.
Slips in the above-mentioned pipeline welding counterpart centralizer is a two halves round flange structure, respectively is provided with the through hole of two bolts, and the center is the segment through hole that two semicircles are formed.
Ball seat in the above-mentioned pipeline welding counterpart centralizer is cylinder and rectangular stack, is hollow-core construction in the middle of the bottom, and the bottom surface is curved, and central upper portion is provided with more than half ball chamber, is provided with four tapped blind holes outside the ball chamber.
The beneficial effect of the utility model is: novel in design, make easily, with low cost, easy to operate, time saving and energy saving, safe and reliable, realize that pipeline welding location, counterpart speed are fast, and can satisfy on-the-spot pipeline construction needs, improve construction quality and economic benefit.

At first, pipeline welding counterpart centralizer support 11 down places treating under the weld bond 14 of two pipelines 13.
Secondly, support 5 component assemblies such as grade, be placed on weld bond 14 tops of pipeline 13, ball seat 8 cambered surfaces and pipeline 13 tops are coincide being installed in going up on the leading screw 2.
The 3rd, buckle draw ring 9.
The 4th, through handle 1 rotating threaded shaft 2, adjustment pipeline 13 aligns up to weld bond 14, until clamping.Can carry out welding operation then.
