in the figure, 1-fixed block, 2-hoop, 3-block, 4-first fastening screw, 5-second fastening screw, 6-pressing plate, 7-third fastening screw.

Detailed Description

The present invention is further explained with reference to the drawings and the detailed description, but the scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution of the present invention and the inventive concept within the technical scope of the present invention.

As shown in fig. 1, a pipeline welding butt joint device comprises a fixing block 1, two sides of the fixing block 1 are respectively hinged with arc-shaped hoops 2, free ends of the two hoops 2 are fixedly connected with a stop block 3, two threaded through holes are symmetrically formed in the left side and the right side of the stop block 3, one threaded through hole is in threaded connection with a first fastening screw rod 4, the other threaded through hole is in threaded connection with a second fastening screw rod 5, and the first fastening screw rod 4 and the second fastening screw rod 5 are the same in length; the hoop 2 is also sleeved with a pressing plate 6, the pressing plate 6 is H-shaped, and two ends of the pressing plate 6 are connected through a pin shaft to form a cavity for accommodating the hoop 2; the middle part of the fixed block 1 is also provided with a thread through hole in a penetrating way, the thread through hole is internally connected with a third fastening screw 7, and the third fastening screw 7 extends downwards and is abutted against the middle part of the pressing plate 6.

As a preferred embodiment of the present invention, as shown in fig. 2-a (top view) and fig. 2-b (side view), the bottom of the middle of the pressing plate 6 is an arc surface, and the radian of the arc surface is the same as that of the surface of the pipeline to be aligned; the purpose is at the in-process of rotating the tight clamp plate 6 of the tight threaded rod 7 in downward top of third, makes 6 bottom surfaces of clamp plate with treat that the pipeline contact is stable to mouthful, can not take place to sideslip the skew, guarantees to mouthful precision. In addition, two sides of the pressure plate 6 are provided with two flanges extending outwards, so that the contact area is increased, and the placement stability is further improved.
