Tool and method for installing novel inserting opening of hydraulic pipeline

The invention discloses a tool and a method for installing a novel inserting opening of a hydraulic pipeline. The method comprises the following steps of (1) welding a sleeve at the installation position of a branch pipeline according to a technical document, placing a drill head of a magnetic drill at the inner part of the sleeve, providing a hole on a main pipeline, then removing the sleeve, and polishing the hole; (2) stretching a magnetic bar to the inner part of the main pipeline through the hole, and extracting iron fillings which are generated during the hole processing; (3) placing a bearing hydraulic connector which is processed and prepared at the position of the hole of the main pipeline, assembling and welding; and (4) placing the branch pipeline in an inserting hole of the bearing hydraulic connector, and welding. According to the method for installing the novel inserting opening of the hydraulic pipeline, disclosed by the invention, the branch pipeline and the hydraulic connector adopt bearing type welding, the requirement on the technical level of an operator is greatly reduced, and the construction quality is increased; the construction can be carried out in smaller space, and the requirement on the construction environment is greatly reduced; and by adopting the construction method, the welding work amount is reduced, the number of long flaw detection welded junctions is reduced, the construction period is saved, and the method is economic and practical.
