Description

A thrust head installation device for maintenance of large and medium-sized hydroelectric generating units

technical field

The utility model relates to a thrust head installation device, in particular to a thrust head installation device for overhauling large and medium-sized hydraulic generator sets.

Background technique

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 bolts are tightened, iron filings will fall and be caught on the flange joint surface, which will cause the failure of the entire installation work. The above-mentioned process is inefficient and has many disadvantages, so it needs to be improved thoroughly.

Utility model content

The utility model aims to solve the problems of human error, low efficiency and many disadvantages in the installation of the thrust head of the existing large and medium-sized hydroelectric generating units, and further proposes a thrust head installation device for large and medium-sized hydro-generating units during maintenance.

The technical scheme adopted by the utility model to solve the above problems is: the utility model comprises a high-pressure electric oil pump, a multi-way joint, a main pipeline, a plurality of branch pipelines, a plurality of lifting tools and a plurality of fixing frames, and the plurality of lifting tools are circular setting, the multi-way joint is arranged in the center of the circle, and a fixing frame is respectively fixedly installed on the upper end of each lifting tool, and the oil outlet of the high-pressure electric oil pump is connected with the oil inlet of the multi-way joint through the main pipe, and the multi-way Each oil outlet of the joint is respectively connected with a corresponding oil inlet of a lifting tool through a branch pipeline.

The beneficial effect of the utility model is: during the installation process, the lifting of the thrust head is very stable and rises at a uniform speed, and at the same time, it can also realize automatic level adjustment during the lifting process, so that the bolts and holes can be aligned, and the connecting bolts can be inserted accurately. pass through the flange screw holes, and keep the bolts in a tight state, tighten the nuts, and insert them in place at one time, saving time and effort; the utility model avoids the iron filings entering the flange joint surface, has no damage to the equipment, and avoids the problem of rework , the whole installation work is successful at one time; the utility model changes the installation process of the thrust head, improves the installation efficiency of the thrust head, and reduces the risk of failure during the installation process.
