[0031] Reference Figure 1-2The utility model provides an auxiliary assembly tool for pipe flange elbows, which is designed to simplify and optimize the welding assembly and installation process between the pipe and the flange, or between the pipe and the elbow, to ensure the convenience of connection. The specific structure includes a pipe support 1, two support frames 3 and two connecting devices. Among them: the pipe support 1 is used to support the pipe to be assembled so as to achieve the position limitation of the pipe to be assembled; the two support frames 3 are respectively fixed on both sides of the pipe support 1 along the length direction of the pipe support 1; the two connecting devices are arranged in a one-to-one correspondence with the two support frames 3, and the connecting device is installed on the support frame 3, and the connecting device includes a support plate 4, a rotating plate 5, a clamping mechanism and a connecting plate 9. The support plate 4 and the rotating plate 5 are arranged in the horizontal direction. At least one support plate 4 can be fixedly slidably connected to the support frame 3 along the length direction of the pipe support member 1. The rotating plate 5 is fixedly rotatably connected above the support plate 4, that is, the rotating plate 5 can be fixedly connected above the support plate 4. The rotating plate 5 can rotate circumferentially along the rotation axis in the vertical direction. A clamping mechanism and a connecting plate 9 are installed on the rotating plate 5.

[0032] When welding and assembling the pipeline and the flange, place the pipeline to be assembled on the pipeline support 1, fix the flange to be assembled on the connecting plate 9 by fasteners, rotate the rotating plate 5 to make the flange to be assembled perpendicular to the pipeline to be assembled, then slide the support plate 4 to clamp the pipeline to be installed between the two connecting plates 9, and fix the support plate 4 to the support frame 3. At this time, the flange to be assembled and the pipeline to be assembled are abutted, and then welding and assembling can be carried out. Then, the fixation between the flange and the connecting plate 9 and between the support plate 4 and the support frame 3 is released, and the pipeline and the flange are removed for repair welding.

[0033] Similarly, when welding and assembling the pipe and the elbow, the pipe to be assembled is placed on the pipe support 1, and the elbow to be assembled is clamped by the clamping mechanism. The rotating plate 5 is rotated to make one end of the elbow to be assembled perpendicular to the pipe to be assembled. Then, the pipe to be installed is clamped between the two connecting plates 9 by sliding the support plate 4, and the support plate 4 is fixed to the support frame 3. At this time, one end of the elbow to be assembled is abutted against the pipe to be assembled, and then welding and assembling can be carried out. Then, the fixation between the flange and the connecting plate 9 and the support plate 4 and the support frame 3 is released, and the elbow and the flange are removed for repair welding.

A positioning hole 12 is arranged on the support plate 4, and the lower end of the fixing rod 7 passes through the rotating plate 5 and is detachably connected to the positioning hole 12.

[0039] When switching between the welding pairing between the pipe and the flange and the welding pairing between the pipe and the elbow, it is only necessary to lift up the rotating plate 5 so that the lower end of the fixing rod 7 is disengaged from the positioning hole 12, and then rotate 180 degrees around the rotation axis of the rotating component 11, and lower the rotating plate 5 again so that the lower end of the fixing rod 7 is embedded in the positioning rod. At this time, the switching process of different pair installations is completed.

[0040] Preferably, at least one of the support plates 4 extends downward along its width edge to form a sliding plate 13, and a sliding groove 14 is arranged on the support frame 3 arranged opposite to the sliding plate 13.
