Gas turbine rotor disk stacking device

Abstract

The gas turbine rotor disk stacking device includes a bottom plate, a rear half shaft arranged at the center of the bottom plate, and two uprights arranged on both sides of the rear half shaft. The two ends are connected to the top of the column respectively, and an inverted jack is provided under the beam support, and a middle guard plate with two ends set on the columns on both sides is set under the jack, and a through hole is opened in the center of the middle guard plate. The rod passes through the through hole, and its top is connected with the upper top plate. The outer ring of the through hole is provided with adjustment bolts for adjusting the levelness of the upper top plate; there are 15 tie rods on the rear half shaft, and the tie rod holes of the rotor discs to be stacked Pass through the pull rod at the corresponding position, place the rotor disc on the rear half shaft, the bottom of the ejector rod is in contact with the center hole of the rotor disc, and drive the jack to apply force to the top plate to make the ejector rod move downward, so that the corresponding The discs adjacent to the rotor are sequentially fixed on the rear half shaft through the interference fit of the concave notch and the convex notch on the discs.

Description

technical field [0001] The invention relates to the field of gas turbine auxiliary equipment, in particular to a gas turbine rotor disk stacking device. Background technique [0002] Gas turbine compressor discs, such as figure 1 and figure 2 As shown, its structure has the following characteristics: (1) There are 15 tie rod holes on each level of wheel disc, and the pitch circles are the same. (2) The center holes of the discs at all levels have a convex stop on the steam inlet side and a concave stop on the steam outlet side. In the prior art, the gas turbine rotor discs are generally assembled horizontally when stacked, but when assembled horizontally, the discs are prone to bending deformation due to gravity. Therefore, there is an urgent need for a stacking device, which can not only meet the technical requirements of ultra-high verticality (0.01mm) and parallelism (0.01mm) after assembly of the wheels at all levels, but also greatly reduce the cost of tooling and f...
