plate 12-2 is positioned at the side end of the pipeline repairing position, and therefore, a conveying medium in the pipeline cannot leak to the, and then will not influence the adjustment work of the second arc 12-2, after this apparatus is pushed to the pipeline needing to be repaired under the end, connect the electric telescopic rod 2 with the storage battery 44 through the wire again, and start the output terminal extension or retraction of four electric telescopic rods 2 at the same time, so the distance between the counterweight plate 1 and the ground changes, so the distance between the second arc 12-2 and the pipeline also changes, and then can adjust the distance between the inner arc of the second arc 12-2 and the pipeline by controlling the electric telescopic rod 2, thus can make the axial lead of the second arc 12-2 and the axial lead of the pipeline adjust to be identical effectively, then put the first arc 12-1 back to the original position, make the first arc 12-1 and the second arc 12-2 make up a complete cylinder 12, then sliding the threaded rod 17 into the U-shaped opening 19, screwing the locking nut 18, so that the joint of the first arc-shaped plate 12-1 and the second arc-shaped plate 12-2 is tightly attached, then selecting an arc-shaped steel plate 39 matched with the external radian of the pipeline according to the external radian of the pipeline to be repaired, fixing the arc-shaped steel plate 39 on the arc-shaped groove on the top surface of the fixing plate 38 through the locking bolt 41, then starting the motor 4, driving the reducer 5 to rotate through the motor 4, so that the output shaft of the reducer 5 can drive the lead screw 8 to rotate, driving the lead screw nut 9 to move left and right when the lead screw nut 9 moves left and right, synchronously driving the cylinder 12 to move to the damaged part of the pipeline through the motor 4, then respectively starting the first motor 24 and the hot air blower 28, driving the gear 26 to rotate through the first reducer 25 after the first motor 24 is started, the gear 26 rotates along the inner arc surface of the inner gear 22, because the mounting plate 23 is fixedly connected with the first T-shaped sliding block 21, the gear 26 can synchronously drive the mounting plate 23 to rotate around the pipeline, thus when the inner arc surface of the arc-shaped steel plate 39 is opposite to the damaged part of the pipeline, the operation of the first motor 24 is stopped, and the output end of the hydraulic cylinder 27 is controlled to extend through the hydraulic station 45, so that the inner arc surface of the arc-shaped steel plate 39 is attached to the damaged part of the pipeline, and thus the rubber pad 40 in the mounting groove 43 on the inner arc surface of the arc-shaped steel plate 39 can press the damaged part of the pipeline, thereby achieving the purpose of preventing the leakage of the conveying medium, because of the arrangement of the square spring cylinder 34, the spring 36 arranged in the square spring cylinder can effectively buffer the force of the hydraulic cylinder 27 pushing against the pipeline, thereby effectively playing a protection role, and the hot air blown out by the hot air blower 28 can sequentially, thus, the drying work of the leakage medium at the contact part of the arc-shaped steel plate 39 and the pipeline can be effectively accelerated, the welding work between the arc-shaped steel plate 39 and the pipeline can be accelerated, when the leakage of the conveying medium at the pipeline damage part is prevented, and after the leakage medium at the contact part of the arc-shaped steel plate 39 and the pipeline is dried, the welding work between the arc-shaped steel plate 39 and the pipeline can be executed, according to the auxiliary device for welding and repairing the large-scale pipeline, the arc-shaped steel plate 39 can be pressed to the pipeline damage part through the electric telescopic rod 2, the motor 4, the first motor 24 and the hydraulic cylinder 27, the manual pressing is not needed, the labor capacity of workers is saved, meanwhile, the condition that the conveying medium is leaked to the bodies of the workers is effectively prevented, the personal safety of the workers is guaranteed, and the leakage liquid material at the welding part can be quickly dried through the, thereby improving the working efficiency. After the welding operation between the arc-shaped steel plate 39 and the pipeline is finished, the locking bolt 41 is unscrewed, and the fixing plate 38 is separated from the arc-shaped steel plate 39, so that the auxiliary operation of welding and repairing the damaged part of the pipeline can be completed.
