Each stationary blade seat is supported and placed by a group of first support frames 21 and a group of second support frames 31 (in the invention, 2 first support frames 21 and 2 second support frames 31 are used for supporting one stationary blade seat together). Therefore, a plurality of static blade seats can be stacked on the static blade seat placing frame at the same time, the static blade seats are prevented from being placed on a sleeper on site one by one, a large amount of equipment placing space is saved, and the static blade seat placing frame is favorable for on-site standardized management. In addition, the stationary blade seat is placed by the stationary blade seat placing frame in a suspension mode, and when maintenance personnel check and maintain the stationary blade seat, maintenance work can be carried out without lifting the equipment, so that a large amount of maintenance time is saved. The first side support 2 and the second side support 3 which are arranged on two sides of the base 1 form a frame structure, the stationary blade seat for placing is surrounded, the possibility that a person accidentally bumps the stationary blade can be effectively avoided, and the safety of precision equipment is protected.
It should be noted that, in the present invention, each static blade seat placing support is provided with 3 groups of first support frames 21 and 3 groups of second support frames 31, each group is provided with 2 support frames, so that three static blade seats can be placed on one static blade seat placing support at the same time, and two static blade seats can be completely placed on 6 static blade seats. Of course, the number of the first support frame 21 and the second support frame 31 may be adjusted according to actual requirements, and is not limited herein.
Alternatively, referring to fig. 2, the first support frame 21 is rotatably disposed on the first side bracket 2, and the second support frame 31 is rotatably disposed on the second side bracket 3.
In this embodiment, because quiet leaf seat is heavier, need hoist during the placement, need down to place from last promptly, in order to facilitate the placing of quiet leaf seat, first support frame 21 and the rotatable setting of drawing in of second support frame 31, draw in the rotatory first support frame 21 and the second support frame 31 on upper strata earlier like this, place quiet leaf seat on the first support frame 21 of lower floor and the second support frame 31 after, rotatory first support frame 21 and the second support frame 31 of expanding the upper strata again, place quiet leaf seat on the first support frame 21 of upper strata and the second support frame 31.
Further, referring to fig. 3, the first side bracket 2 is further provided with a first limiting baffle 22 for limiting the rotation of the first support bracket 21, and the maximum rotation angle of the first support bracket is 90 °; the second side bracket 3 is further provided with a second limiting baffle 32 for limiting the rotation of the second support frame 31, and the maximum rotation angle of the second support frame 31 is 90 °.
In this embodiment, the first limit baffle 22 and the second limit baffle 32 are provided, which is beneficial to quickly adjusting the first support frame 21 and the second support frame 31 to the support position, so that the placing work can be quickly and smoothly performed. It should be noted that the first limit stop 22 and the second limit stop 32 at the bottom layer may be directly fixedly disposed, not rotatably disposed, and is not limited herein.
Alternatively, in order to protect the seal surfaces of the vane seat (i.e., the contact surfaces of the vane seat and the first and second support frames 21 and 31), the contact surfaces of the first and second support frames 21 and 31 and the vane seat are each provided with a buffer layer, which may be made of teflon.
Optionally, in order to meet the inspection requirement of a maintenance worker on the stationary blade seat, the distance between two adjacent groups of first support frames 21 is 200-450 mm, and the distance between two adjacent groups of second support frames 31 is 200-450 mm. When placing on quiet blade seat puts the support simultaneously like this polylith quiet blade seat, have suitable space between the quiet blade seat of adjacent, supply the maintenance personal to inspect the quiet blade seat of placing.
Optionally, referring to fig. 1, the top of each of the first side bracket 2 and the second side bracket 3 is provided with a lifting point 4 for lifting. Therefore, after the static blade seat placing support is placed, the static blade seat placing support can be directly lifted and moved, and equipment can be conveniently operated.
The working process of the bracket for placing the stator blade seat of the nuclear power generator is briefly described below with reference to fig. 1-3:
firstly, the first support frame 21 and the group of second support frames 31 on the upper layer in the stator blade seat placing support are folded in a rotating mode, the first support frame 21 and the group of second support frames 31 on the bottommost layer are unfolded in a rotating mode, and a stator blade seat is placed on the first support frame 21 and the group of second support frames 31 on the bottommost layer in a lifting mode.
Then, the first support frame 21 and the group of second support frames 31 of the adjacent high-rise are rotated and unfolded, the next static blade base is hoisted and placed on the unfolded first support frame 21 and the group of second support frames 31, and the static blade base is hoisted and placed on the static blade base placing support block by block according to the steps.
In addition, after the stator blade seat on the stator blade seat placing support is placed, the whole stator blade seat placing support can be lifted and shifted through the lifting points 4, and a suitable position is placed.
According to the embodiment of the invention, through the matching of the plurality of groups of first support frames and the second support frames, the stacking of the plurality of static blade seats can be realized, the static blade seats are prevented from being placed on a sleeper on site one by one, a large amount of equipment placing space is saved, and the standardized management on site is facilitated. The static blade seat is placed by the static blade seat placing frame in a suspension mode, and when maintenance personnel check and maintain the static blade seat, maintenance work can be carried out without lifting the equipment, so that a large amount of maintenance time is saved. In addition, the first side support and the second side support arranged on the two sides of the base form a frame structure, the fixed blade base for placing is surrounded, the possibility that the fixed blade is accidentally damaged by personnel can be effectively avoided, and the safety of precision equipment is protected. The static blade seat placing support is simple in structure, stable and safe in support, convenient to maintain and control and convenient to popularize and apply on a large scale.
