Embodiment 1

[0023] The embodiment of the present invention provides a bracket for placing the stator blade seat of a nuclear power generator, which is suitable for placing the stator blade seat. See figure 1 , the vane seat placement bracket may include:

[0024] The base 1 is arranged on the first side bracket 2 and the second side bracket 3 on both sides of the base 1, multiple groups of first support frames 21 are arranged on the first side bracket 2 in sequence, and multiple groups are arranged on the second side in sequence The second supporting frame 31 on the side frame 3 .

[0025] join image 3 , each set of first support frames 21 may include: at least two first support frames 21 arranged side by side and jointly used to support one end of the vane seat; each set of second support frames 31 may include: at least two side by side The second support frame 31 is provided and used to support the other end of the vane seat.

[0026] In this embodiment, the vane seat is arc-shaped,...

Abstract

The invention discloses a nuclear power generator stationary blade seat storage support. The nuclear power generator stationary blade seat storage support comprises a base, a first side edge support,a second side edge support, first support frames and second support frames. By means of the nuclear power generator stationary blade seat storage support, multiple stationary blade seats can be stacked through cooperation between the multiple first support frames and the multiple second support frames; the problem that the stationary blade seats are put on site sleepers one by one; plenty of equipment storage spaces are saved; and standardized management over the site can be conducted conveniently. The stationary blade seats are put on the stationary blade seat storage support; when the stationary blade seats are checked and maintained by maintenance personnel, the maintenance personnel can perform maintenance work without hoisting equipment; and a great amount of maintenance time is saved. In addition, the first side edge support and the second side edge support arranged at the two sides of the base form a frame structure; the placed stationary blade seats are surrounded; the possibility that the stationary blade seats are touched to be damaged by the personnel by accident can be effectively avoided; and safety of the precision equipment is protected. The stationary blade seat storage support is simple in structure, steady and safe to support and convenient to maintain, operate and control and can be applied and popularized on a large scale conveniently.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant maintenance, in particular to a bracket for placing a static blade seat of a nuclear power generator. Background technique [0002] The biggest difference between the QFSN-1100-4 1100MW nuclear power generator and other generator sets is that the front end adopts the axial flow multi-stage compression fan design (8 stages in total), and the corresponding position is designed with stator blades (6 pieces in total in one circle) , The cooling system of the generator adopts the cooling method of multi-stage axial flow and stator blade seat, and the cooling effect is good. [0003] However, the vane seat of this nuclear power generator is not equipped with a vane seat placement bracket, and the vane seat is placed directly on the sleepers, resulting in an excessively large maintenance site; and because the vane seat is a precision device, this placement method The vane cannot be protected...
