Abstract

The utility model relates to a rapid pipe buttwelding and aligning device which can ensure pipe quality and is convenient to transport and use. The rapid pipe buttwelding and aligning device comprises a bottom plate, a clamp set, a screw rod and a hand wheel; the clamp set comprises a left K-shaped clamp and a right K-shaped clamp which are respectively provided with a K-shaped opening in the same height position; the left K-shaped clamp is arranged on the bottom plate, the bottom of the right K-shaped clamp is arranged in a sliding hole, and both the left K-shaped clamp and the right K-shaped clamp are provided with threaded holes in the in the same height position; the left-section threads of the screw rod serve as right threads which correspond to the right thread hole in the left K-shaped clamp, and the right-section threads of the screw rod serve as left threads which correspond to the left thread hole in the right K-shaped clamp; and the hand wheel is arranged at the left end of the screw rod. The rapid pipe buttwelding and aligning device which is used for welding pipes, in particular for pipes on the drilling site has the advantages of ensuring the consistent coaxiality of welded pipes, light weight, small volume, convenient transportation and low cost.

Description

Pipe welding rapid abutting joint alignment device

Technical field

The utility model relates to a kind of butt joint alignment device that is used for the pipe welding.

Background technology

The pipe butt joint is a kind of construction operation of frequent application; In the drilling engineering operation, when lock of tool drilling takes place,, need the butt joint milling shoe and mill pipe in order to remove lock of tool drilling.The pipe butt joint need be carried out centering, and in the workshop, the normal pneumatic alignment device of special use that uses carries out centering.The pneumatic alignment device weight of prior art is bigger, and being unsuitable in the open air, situ of drilling well uses.And the range estimation centering, error is bigger, and the concentricity of welding back pipe is poor, influences construction quality.

Summary of the invention

Technical problem to be solved is, provides a kind of and guarantees that quality is convenient to carry the pipe welding rapid abutting joint alignment device of use.

Solve the technical scheme of its technical problem, comprise base plate, Jia group, screw mandrel and handwheel; Two parallel chutes are arranged on the base plate; Jia group has two groups, two K Xing Jia about every Zu of Jia group comprises, K shape mouth is arranged on the equal height of K Xing Jia , the K shape mouth of two K Xing Jia is relative, left side K clamp is contained on the base plate and maintains static, and right K clamp is contained in its bottom in the chute of base plate and can slides in chute, on the equal height of two K Xing Jia screwed hole is arranged, on the K Xing Jia of a left side right-hand thread hole is arranged, on the right K Xing Jia left-hand thread hole is arranged; Two sections screw threads are arranged on the screw mandrel, screw mandrel left side section screw thread be with left K Xing Jia on the corresponding right-hand thread section in right-hand thread hole, the right section of screw mandrel screw thread be with right K Xing Jia on the corresponding left-hand thread section in left-hand thread hole, screw mandrel left side section screw thread combines with right-hand thread hole on the left K Xing Jia , and the right section screw thread of screw mandrel combines with left-hand thread hole on the right K Xing Jia ; Handwheel is contained in the left end of screw mandrel.

When carrying out weld job, move the butt joint alignment device to the on-the-spot pad place that needs welding pipe, shake handwheel the axis of two tubes is aligned, can weld with the end that two Zus of Jia groups are respectively clamped a pipe.

Beneficial effect: the utility model is applied to the pipe welding, and particularly the pipe at situ of drilling well welds.Beneficial effect is can guarantee the axis concentricity unanimity of welding pipe, the assurance welding quality; Be applicable to the welding of various diameter pipes, in light weight, volume is little, convenient in carrying, low cost of manufacture.

Description of drawings:

Fig. 1 is a structure chart of the present utility model.Among Fig. 1,1 is base plate, and 2 are Jia group, and 3 be screw mandrel, and 4 be handwheel, and 5 be chute, and 6 be left K Xing Jia , and 7 is right K clamp, and 8 is K shape mouth, and 9 is the left section screw thread of screw mandrel, and 10 is the screw mandrel right side section screw thread.

The specific embodiment

The specific embodiment is as follows, comprises base plate 1, Jia group 2, screw mandrel 3 and handwheel 4; Two parallel chutes 5 are arranged on the base plate 1; Jia group has two groups, two K Xing Jia about every Zu of Jia group comprises, K shape mouth 8 is arranged on the equal height of K Xing Jia , the K shape mouth 8 of two K Xing Jia is relative, left side K clamp 6 is contained on the base plate 1 and maintains static, and right K clamp 7 is contained in chute 5 interior can the slips of base plate 1 in chute 5 bottom it, on the equal height of two K Xing Jia screwed hole is arranged, on the left side K Xing Jia 6 the right-hand thread hole is arranged, on the right K Xing Jia 7 the left-hand thread hole is arranged; Two sections screw threads are arranged on the screw mandrel 3, screw mandrel left side section screw thread 9 be with left K Xing Jia 6 on the corresponding right-hand thread section in right-hand thread hole, the right section of screw mandrel screw thread 10 be with right K Xing Jia 7 on the corresponding left-hand thread section in left-hand thread hole, screw mandrel left side section screw thread 9 combines with right-hand thread hole on the left K Xing Jia 6, and the right section screw thread 10 of screw mandrel combines with left-hand thread hole on the right K Xing Jia 7; Handwheel 4 is contained in the left end of screw mandrel 3.
