Abstract

The invention relates to a mounting device for a push head, in particular to a mounting device for a push head for the maintenance of a large and medium-size water-turbine generator set, and solves the problems, for example, the man-made deviation is caused during the mounting of the push head of the traditional large and medium-size water-turbine generator set, the efficiency is low, and the defects are more. The mounting device comprises a high-pressure electric oil pump, a multipass joint, a main pipeline, a plurality of branch pipelines, a plurality of lifting tools and a plurality of fixing brackets, wherein the lifting tools are arranged in a circle with the multipass joint in the center; the upper end of each lifting tool is respectively fixed with one corresponding fixing bracket; an oil outlet of the high-pressure electric oil pump is connected with an oil inlet of the multipass joint through the main pipeline; each oil outlet of the multipass joint is connected with the oil inlet of the corresponding lifting tool through one branch pipeline. The mounting device is used for mounting the push head of the large and medium-size water-turbine generator set.

Description

technical field [0001] The invention relates to a thrust head installation device, in particular to a thrust head installation device for large and medium-sized hydroelectric generating sets. Background technique [0002] Generally known large and medium-sized hydro-generator thrust head is installed, and the method is that after the thrust head is connected to the mirror plate, it falls on the thrust tile, and the rotating parts such as the rotor fall on the brake brake, and then the connecting bolt is passed through on the upper side of the flange. , tighten the bolts with a pneumatic wrench, and lift the thrust head up. The installation process requires the cooperation of multiple people. The bolts are fastened in four symmetrical directions of the flange. Due to the different technical proficiency of the workers and the difference in construction experience, human errors often occur during installation, and repeated installation is required. At the same time, when the b...
