Abstract
The cylinder lifting device of the steam turbine comprises a profile steel cross beam, connecting steel plates, square plugs and jacks, wherein the connecting steel plates are arranged on two sides of the profile steel cross beam, the two square plugs are arranged on the connecting steel plates, and the jacks are arranged at two ends of the profile steel cross beam. During the use, arrange the shaped steel crossbeam in cat claw top, hang 4 connecting steel plates on the crossbeam again, take out the original cuboid locating piece of equipment from the constant head tank again, insert the constant head tank with the square plug of cuboid of this device, and both ends pass the square hole of connecting steel plate, so long as jack-up crossbeam, the crossbeam pulls up square plug through 4 connecting steel plates, and square plug just grabs through the cat and lifts up the cylinder body.
Description
Technical Field
The utility model belongs to a mechanical tool is a steam turbine lifts jar device.
Background
The basic structure of steam turbine bearing frame and cylinder body, the cylinder passes through cat claw and cat claw locating pin location on big bearing frame, little bearing frame, and whole cylinder 70 t's weight all presses on two bearing frames, and the sliding pin system of unit sets up in the bottom of big bearing frame, and regular need is overhauld, overhauls every time and all need hang the cylinder and just can implement to overhaul the sliding pin system, and the spare part that the cylinder inside and bottom set up, the pipeline is very many, falls to spend the cylinder time and energy. The construction period is long and the maintenance cost is high.
The prior art has the following defects: the cylinder body and the cylinder body auxiliary equipment are disassembled and assembled in 4 days, the construction period is long, the labor intensity is high, the maintenance cost is high, and the production efficiency of the unit is reduced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a steam turbine lifts jar device need not demolish any auxiliary assembly inside and outside the cylinder body, can easily lift up 2 ~ 3mm in cylinder body front end, takes the bearing frame out.
The technical scheme of the utility model:
the cylinder lifting device of the steam turbine comprises a profile steel cross beam, connecting steel plates, square plugs and jacks, wherein the connecting steel plates are arranged on two sides of the profile steel cross beam, the two square plugs are arranged on the connecting steel plates, and the jacks are arranged at two ends of the profile steel cross beam.
During the use, arrange the shaped steel crossbeam in cat claw top, hang 4 connecting steel plates on the crossbeam again, take out the original cuboid locating piece of equipment from the constant head tank again, insert the constant head tank with the square plug of cuboid of this device, and both ends pass the square hole of connecting steel plate, so long as jack-up crossbeam, the crossbeam pulls up square plug through 4 connecting steel plates, and square plug just grabs through the cat and lifts up the cylinder body.
The technical effects of the utility model are that: the construction process is simplified; the construction quality is ensured; the labor intensity is reduced, the construction period is shortened, and the production efficiency is improved.
