Detailed Description
The technical solution of the present utility model is further described below, but the scope of the claimed utility model is not limited to the above.
As shown in fig. 1 to 5.
The utility model provides a pipeline construction equipment that is geared to needs of job, include:
the outer surface of the pipeline is provided with two sliding cylinders 4 with through grooves for installing threaded blocks 6, and the two sliding cylinders 4 correspond to the two pipelines 1;
the sliding cylinders 4 correspond to the two threaded blocks 6, the two bolts 7 and the two arc-shaped pressing plates 2, the bolts 7 are screwed on the threaded blocks 6, the arc-shaped pressing plates 2 are arranged on the inner face of each sliding cylinder 4, the sliding cylinders 4 can slide on the arc-shaped pressing plates 2, and the bolts 7 are screwed through the threaded blocks 6 and then tightly push the arc-shaped pressing plates 2 to press the outer walls of the pipelines 1;
the limiting plates 3 which are axially and slidably arranged on the arc-shaped pressing plates 2 cannot be used by the sliding rods 21, the connecting rods 5 are arranged between the limiting plates, and the sliding cylinders 4 slide by taking the connecting rods 5 as a sliding basis.
The outside of the arc-shaped pressing plate 2 is rotatably provided with a supporting sleeve 22, the supporting sleeve 22 is eccentrically arranged, and the supporting sleeve 22 can drive the sliding cylinder 4 to slide on the connecting rod 5 after rotating.
The corresponding arc pressing plate 2 on each sliding cylinder 4 is correspondingly contacted with the pipeline 1, the bolt 7 is screwed on the threaded block 6, the bolt 7 drives the arc pressing plates 2 in the two sliding cylinders 4 to be clung to the pipeline 1 for friction, the supporting sleeve 22 on one side of the arc pressing plate 2 is rotated, when one supporting sleeve 22 is rotated, the arc pressing plate 2 of one sliding cylinder 4 is clung to the pipeline 1 for friction to provide a stress foundation for the limiting plate 3 without moving, the sliding cylinder 4 takes one pipeline 1 to approach the opposite sliding cylinder 4 on the basis of the connecting rod 5, then the supporting sleeve 22 on the other side of the arc pressing plate 2 is rotated, the sliding cylinder 4 takes the other pipeline 1 to approach the opposite sliding cylinder 4 on the basis of the connecting rod 5, and during welding, the axial force is generated by the friction force generated by the corresponding clung of the two arc pressing plates 2 oppositely arranged in the two sliding cylinders 4 and the two pipelines 1, so that the problem that the axial force is generated during welding cannot be offset during the welding of the two pipelines in an independent axial correspondence mode is solved, and the position stability during the welding of the two pipelines is improved.
