Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a flange welding auxiliary device for a gas pipeline, including: drive screw 1, traveling nut 2, rotatory handle 3, support kicking block 4, connecting rod 5, backup pad 6, drive screw 1 around both sides open respectively and have the external screw thread, and the screw thread opposite direction of both sides, traveling nut 2 be provided with two, two traveling nut 2 connect respectively in drive screw 1's both sides, 3 rigid couplings of rotatory handle in drive screw 1's outer end, connecting rod 5 two be a set of, the inner of two connecting rods 5 of a set of is respectively through selling axle bed swing joint on two traveling nut 2, and the outer end is respectively through selling axle bed swing joint in the inboard that supports kicking block 4, and the upper and lower bilateral symmetry that moves nut 2 is provided with two sets of connecting rods 5, 6 terminal rigid couplings of backup pad in the outer end that supports kicking block 4, the contained angle between backup pad 6 and the support kicking block 4 is the right angle.
Furthermore, a sliding groove is formed in the supporting plate 6, a moving block 7 is arranged in the sliding groove in a sliding mode, a positioning bolt 8 is fixedly connected to the moving block 7, and a positioning nut 9 is connected to the positioning bolt 8 through threads.
Further, the inner side of the supporting top block 4 is uniformly provided with strip-shaped grooves 10 for improving friction.
The working principle is as follows: the utility model provides a gas pipeline's flange piece welding auxiliary device, during the use, carry out position control with two movable blocks 7 earlier, pass the installation through-hole at both ends about the flange connection piece with two positioning bolt 8 again, use set nut 9 tentatively fixed the flange connection piece, stretch into the pipe fitting port with driving screw 1 again, extrude the inboard of backup pad 6 until the port of pipe fitting, twist and move driving screw 1, two traveling nut 2 are close to each other this moment, under the transmission of connecting rod 5, two intervals that support kicking block 4 progressively increase, thereby extrude the inside of pipe fitting, along with the increase of pressure, the device is fixed to the port of pipe fitting, it can be fixed the port of pipe fitting with the flange connection piece to twist set nut 9 once more.
