Abstract
The utility model discloses a fast pipeline opening alignment device, which comprises a clamping body and a fastening screw bolt, wherein the clamping body is a hollow sleeve pipe, in addition, a cut penetrating through the upper and lower end parts of the sleeve pipe is formed in the pipe wall of the sleeve pipe in the length direction of the sleeve pipe, at least one groove opening is formed in the pipe wall of the sleeve pipe in the circumferential direction of the sleeve pipe, fixing plates are respectively and fixedly arranged on the outer side wall of the pipe wall of the sleeve pipe at two sides of the cut, and the two fixing plates are connected with a screw nut through the fastening screw bolt. The fast pipeline opening alignment device has the advantages that in the use process, the screw bolt is tightly screwed so that the screw bolt receives stress from the fixing plates until the inner side surface of the clamping body completely and tightly presses two pipelines to be welded, on the one hand, the coaxiality of the two pipelines is ensured, on the other hand, bridging spot welding and cutting work procedures are omitted, the work procedures are simplified, and the work efficiency is improved; in addition, a welding seam between the butt welding pipelines is mostly shielded by the clamping body, the local sealing is realized on the welding seam, the welding is carried out from a groove hole formed in the clamping body to the welding seam, and the welding quality is improved.
Description
Technical field
The utility model belongs to pipeline welding technical field, relates in particular to a kind of pipeline Quick aligning device.
Background technology
At present, stainless steel pipes, in the time carrying out butt welding, in order to ensure welding quality, often needs to rush argon protection.Existing welding process is, before rushing argon, need the weld seam spot welding of putting up a bridge to docking pipeline, play the effect of fixing two docking pipelines, then weld seam is wound around and makes its sealing with adhesive tape, then rushing argon, after rushing argon and completing, carry out welding, after welding completes, need spot welding to put up a bridge and cut off; There is more defect in this welding method: 1, docking pipeline is in the time of counterpart, and normally manual operation, easily causes mismatch when welding; 2, use rubber belt sealing then to rush argon, the more difficult control of the stability of protection and quality; 3, complex operation, the fixed of two docking pipelines realized by bridging spot welding, and finally also bridging will be cut off, and affects operating efficiency, and the final mass of welding is also difficult to ensure.
Summary of the invention
In order to solve problems of the prior art, the purpose of this utility model is to provide a kind of pipeline Quick aligning device, can fix two docking pipelines by rapid coaxial line, and carry out partially sealed, thereby reach good welding quality.
In order to realize foregoing invention object, the utility model adopts technical scheme as described below:
A kind of pipeline Quick aligning device, comprise clamping body and fastening bolt, described clamping body is a hollow sleeve, and on sleeve pipe tube wall, be provided with along its length the otch at the upper and lower both ends of consistent sleeve-penetrating, on sleeve pipe tube wall along its circumferential at least one notch that offers, on the lateral wall of the sleeve pipe tube wall of described otch both sides, be installed with respectively fixed head, two fixed heads connect by fastening screw screw bolt and nut.
Further, described clamping body is made up of two curved splints, one end of two curved splints is hinged, on the lateral wall of two curved splint other ends, be equipped with fixed head, two fixed heads connect by fastening screw screw bolt and nut, and described two curved splints splicing besieged city one is for clamping the through hole of pipeline; In described two curved splints, have at least on the sidewall of and all offer circumferential slotted eye.
Further, on described two fixed heads, all offer the hole for wearing fastening bolt, wherein on the lateral surface of a fixed head, be welded with nut, and the central axis of nut with this fixed head on the central axes in hole; Described fastening bolt is made up of the double-screw bolt of one end and the nut-welding of the other end, and the central axis of nut and the central axis of double-screw bolt mutually vertical.
Owing to adopting technique scheme, the utlity model has following superiority:
Pipeline Quick aligning device of the present utility model in use, tight a bolt, make it stressed in fixed head, until the medial surface of clamping body compresses two pipelines that need welding completely, ensure on the one hand the axiality of two pipelines, exempt on the other hand bridging spot welding and excision operation, simplified operation and improved operating efficiency; In addition, the weld seam major part between butt welded pipeline is held body and blocks, and butt welded seam has been realized partially sealed, and the slotted eye from clamping body, to weld seam welding, has improved welding quality.
