[0016] See also Figure 1-Figure 4 The utility model provides the following technical solutions: it includes a main support frame 1, an auxiliary support frame 11 is provided on one side of the main support frame 1, a positioning ring 2 is provided on the inner side of the main support frame 1, an adjusting rod 21 is fixedly connected to the top of the positioning ring 2, the adjusting rod 21 slides inside the main support frame 1, a homonymous ring 3 is provided on the inner side of the auxiliary support frame 11, an auxiliary ring 31 is slidably connected to one side of the homonymous ring 3, a driving rod 32 is fixedly connected to the top of the homonymous ring 3, the driving rod 32 slides inside the auxiliary support frame 11, the adjusting rod 21 and the driving rod 32 are both fixedly connected to the top of an extension block 4, the two extension blocks 4 are respectively slidably connected with a connecting block 5 and a rotating rod 51, and the connecting block 5 is rotatably connected to the rotating rod 51.
[0017] In this embodiment: the main support frame 1 is used to support and connect various components, so as to complete the positioning and supporting work of the pipeline connection during the welding process through the cooperation of other components. The auxiliary support frame 11 provided on one side of the main support frame 1 is used to be placed on the outside of the pipeline to be welded. The main support frame 1 is placed on the outside of the welded pipeline. A positioning ring 2 is provided on the inside of the main support frame 1. When the main support frame 1 is placed on the outside of the welded pipeline, the positioning ring 2 will move vertically downward by its own gravity, so that the positioning ring 2 will contact the welded pipeline. The top of the main support frame 1 is provided with an auxiliary support frame 11 on one side of the main support frame 1. The top of the auxiliary ring 31 fixed to the top of the top of the top of the top of the top ring 3 is also fixed with an extension block 4. The inside of the two extension blocks 4 are respectively slid with a connecting block 5 and a rotating rod 51. Due to the connection between the connecting block 5 and the rotating rod 51, when the extension block 4 fixed to the top of the adjusting rod 21 produces a vertical displacement, it will drive the top of the top ring 31 to move synchronously. The ring 3 moves synchronously, so that the centers of the isochronous ring 3 and the positioning ring 2 are kept on the same horizontal line. At this time, the staff can fix the adjusting rod 21 so that the adjusting rod 21 can no longer move in the vertical direction, thereby ensuring that the center of the isochronous ring 3 continues to be kept on the same horizontal line with the center of the positioning ring 2, and the center of the positioning ring 2 corresponds to the pipeline, so that when the staff places the pipeline to be welded on the inner side of the isochronous ring 3, the position of the pipeline to be welded will correspond to the already welded pipeline, the connecting block 5 and the rotating rod 51 can rotate relative to each other, so that the staff can rotate the connecting block 5 or the rotating rod 51 so that when the elbow is placed on the inner side of the isochronous ring 3, the elbow can be connected to the pipeline, and the auxiliary ring 31 sliding on one side of the isochronous ring 3 is used to block and limit the bottom of the pipeline, so that when the staff places the pipeline on the inner side of the isochronous ring 3, the auxiliary ring 31 can be slid to make the auxiliary ring 31 reach the bottom of the pipeline, thereby supporting the pipeline, avoiding the pipeline from being offset during the welding process of the pipeline by the staff, thereby ensuring the welding effect of the pipeline.
[0018] A limiting block 12 is slidably connected to one side of the main support frame 1, and the limiting block 12 is engaged with the adjusting rod 21. The main support frame 1 and the auxiliary support frame 11 are both rotatably connected with supporting diagonal rods 13 on the outside; the limiting block 12 sliding on one side of the main support frame 1 is used to engage and limit the adjusting rod 21, so that when the positioning ring 2 slides vertically to contact the outside of the pipeline, the staff can slide the limiting block 12 to the inside of the adjusting rod 21 to engage and fix the adjusting rod 21 to avoid unnecessary displacement of the adjusting rod 21, thereby ensuring the effect of pipeline welding, and the supporting diagonal rods 13 rotating on the outside of the main support frame 1 and the auxiliary support frame 11 are used to provide support for the main support frame 1 and the supporting diagonal rods 13, so that the main support frame 1 and the auxiliary support frame 11 can be stably located on the outside of the pipeline.
[0019] A plurality of alignment grooves 22 are provided inside the adjusting rod 21, and the limit block 12 can slide inside the adjusting rod 21 through any of the alignment grooves 22; the alignment grooves 22 provided inside the adjusting rod 21 are used to make way for the insertion of the limit block 12, and there are a plurality of alignment grooves 22, so that when the positioning ring 2 drives the adjusting rod 21 to move vertically until it contacts the top of the pipe, the staff can insert the limit block 12 into the main supporting frame 1 and the alignment grooves 22 corresponding to the position, thereby locking and fixing the position of the adjusting rod 21, and thus completing the fixing of the adjusting rod 21.
[0020] A guide groove 33 is provided on one side of the isotropic ring 3, and the auxiliary ring 31 is slidably connected to the isotropic ring 3 through the guide groove 33; the guide groove 33 provided on one side of the isotropic ring 3 is used to guide the sliding of the auxiliary ring 31, so that the auxiliary ring 31 can slide to the bottom of the pipe to be welded when sliding, thereby completing the support and fixation work during pipe welding.
[0021] A clearance groove 41 is provided inside the extension block 4, and the connecting block 5 and the rotating rod 51 slide inside the two extension blocks 4 respectively through the clearance groove 41; the clearance groove 41 provided inside the extension block 4 is used to make way for the sliding of the connecting block 5, so that when the staff places the main support frame 1 on the outside of the welded pipe, the distance between the main support frame 1 and the auxiliary support frame 11 can be changed by sliding the auxiliary support frame 11, and then the Shudie auxiliary support frame 11 can be located outside the position where the pipe needs to be welded, thereby completing the support work for the pipe welding.
[0022] The working principle and use process of the utility model are as follows: when the staff needs to perform overhead welding on the pipeline, the staff can first place the main support frame 1 on the outside of the welded pipeline. At this time, the positioning ring 2 will move vertically downward by its own gravity, so that the positioning ring 2 will contact the top of the welded pipeline. The positioning ring 2 will drive the adjustment rod 21 to move synchronously during the vertical movement, and the adjustment rod 21 will drive the connecting block 5 and the rotating rod 51 to move synchronously through the extension block 4 during the movement. Due to the connection between the connecting block 5 and the rotating rod 51, the heights of the two extension blocks 4 are the same, so that the same-position rings The height of 3 remains the same as that of the positioning ring 2. At this time, the staff can adjust the auxiliary support frame 11 to the pipeline connection installation position. Since the height of the isotropic ring 3 is the same as that of the positioning ring 2, the centers of the positioning ring 2 and the isotropic ring 3 remain on the same horizontal line. At this time, the staff can place the pipeline on the inner side of the isotropic ring 3, and then slide the auxiliary ring 31 so that the auxiliary ring 31 is located below the pipeline. At this time, the auxiliary ring 31 will support the pipeline to avoid unnecessary displacement of the pipeline during the welding installation process. Then the staff can complete the welding work of the pipeline with the support of the auxiliary ring 31.
