The utility model discloses during the use earlier with one of them cohesion device be fixed in the pipeline that has been fixed, with another pipeline hoist that needs the butt joint, put down butt joint end along the inboard two right-angle sides of angle bar, utilize the angle bar to carry out preliminary centering, will treat to take over the pipeline cohesion with another cohesion device, have uneven department to finely tune through guiding mechanism.
The more optimal design: after the locking chain is tensioned, the central plane of the locking chain is vertical to the surface of the angle iron. Therefore, the locking chain is ensured to be vertical to the surface of the pipeline, and the centering accuracy is facilitated.
The distance between the two sets of holding devices is 15-25 cm. The smaller the pitch, the easier the adjustment, but the position of the weld is left.
The adjusting mechanism is composed of a nut and a bolt, the nut is fixed on the edge of the angle iron, and when the bolt is screwed into the nut, the bottom surface of the bolt enters the inner tangent circle of the angle iron. So that the bolt can adjust its position against the pipe to be joined.
The central line of the nut and the central line of the angle iron form an acute angle.
The included angle between the central line of the nut and the central line of the angle iron is 45 degrees.
The width of the angle iron is more than 0.2 times of the diameter of the installed pipeline. The larger the width of the angle iron is, the stronger the centering capacity on the pipeline is, but the weight of the angle iron is increased, which is not beneficial to carrying the tool.
The length of the angle iron is 2-5 times of the diameter of the installed pipeline. The longer the length, the more stable the pipe.
The locking chain is a circular ring chain for hoisting.
The utility model discloses simple structure, convenient to use, pipeline combination seam adjustment accuracy is high, and is efficient, and the range of application is wide, can not harm the pipeline mother metal and can not cause the mother metal to warp, only needs one set of used repeatedly when the piping erection of various different specifications of preparation.

Detailed Description
The embodiments illustrated herein will enable those skilled in the art to more fully understand the present invention, without limiting it in any way, when the present invention is described in detail below with reference to the accompanying drawings.
As shown in fig. 1-4, a pipeline combination joint adjusting and aligning tool comprises angle iron 1, a holding device and an adjusting mechanism, wherein the holding device comprises a locking screw 2, a locking nut 3, a steel plate 4, a locking chain 5 and a hook 6, and all the components are made of Q235B material. The steel sheet middle part system has the hole that can pass locking screw, and the couple is fixed in locking screw's afterbody, and locking chain is the round link chain for the jack-up, and locking chain's one end is fixed in the surface on a right angle limit of angle bar, and the surface on another right angle limit of steel sheet vertical fixation in angle bar, locking screw are fixed in on the steel sheet through lock nut, and on locking chain's the other end was fixed in the couple, the taut back of locking chain, locking chain central plane and angle bar surface vertical. The two sets of the holding devices are respectively a holding device I and a holding device II which are fixed at an upper interval and a lower interval, and the distance between the two sets of the holding devices is 15-25 cm. The upper end of the clasping device I is used for fixing a pipeline to be connected, and the upper edge and the lower edge of the outer edges of the angle irons at the two sides of the clasping device I are respectively fixed with four adjusting mechanisms.
