Description

Technical Field

[0001] The utility model relates to the technical field of nuclear power, in particular to an assembling and mounting frame for supporting bearings of a nuclear power steam turbine generator. Background Art

[0002] The entire turbine generator shaft system of a power plant consists of 1 high-pressure rotor, 2 low-pressure rotors, a generator rotor, and an exciter rotor. There are 9 support bearings designed to support the rotor shaft system (the exciter rotor is a cantilever design, and the exciter rotor is supported by a separate 9 bearings). Every time the unit is overhauled, the 9 bearings of the turbine generator set need to be inspected. Due to the complex maintenance process of the bearing, especially to confirm the wear of the bearing and the metal inspection of the bearing, the bearing needs to be placed on the ground, or the upper and lower half bearings need to be assembled together and then placed on the ground. Since the lower bearing of this model is a spherical pad, it will fall over if the lower bearing is placed on the site alone. For this reason, sleepers or wooden blocks are often placed at the lower bearing of the bearing on site. When the upper and lower bearings are assembled and the inner diameter is measured, in addition to the sleepers below, a crane is also needed to hang the upper half bearing to prevent tipping.

[0003] Specifically, after the lower bearing of the turbine generator is hoisted out, four sleepers are used to pad under the bearing. The time-consuming use of a large number of sleepers has increased the maintenance cost and the potential fire hazard on site. At the same time, if the sleepers are not placed properly on site, there is a risk of the bearing tipping over, which increases the potential safety hazard on site. When measuring the inner diameter of the upper and lower halves of the bearing, the upper half of the bearing must be hoisted with a crane at all times to prevent the bearing from tipping over due to the center of the bearing being at the top after assembly, and to avoid the industrial safety risk of personal injury. For this reason, the crane will be occupied for a long time, affecting the work efficiency of the maintenance site. Utility Model Content
