Abstract
The utility model belongs to nuclear power plant reactor service technique field, and in particular to a kind of reactor protection tube assembly position adjustment workbench.The utility model includes flat board body, angle steel, supporting leg, and the vertical plane of angle steel is fixedly connected with the outer wall of protection pipe component inspection well, and the horizontal plane top of angle steel is fixedly connected with flat board body, and side of the flat board body away from protection pipe component inspection well is provided with supporting leg.The utility model can effectively shorten the overhaul critical path time that the adjustment of protection pipe module position takes, and shorten the overhaul duration, and reduce overhaul collective radioactive dose.
Description
Technical field
The utility model belongs to nuclear power plant reactor service technique field, and in particular to a kind of reactor protection tube assembly position
Put adjustment workbench.
Background technology
During the unit of power station 1,2 reloads circulation pattern transition to long period, to meet that the use of New-type fuel will
Ask, it is necessary to carry out position adjustment to reactor protection tube assembly before fuel assembly is all replaced by fuel assembly.Protection pipe group
The target of part position adjustment is protection tube assembly convex shoulder levels backing plate and bourdon tube lower bolster, is related to and largely uses alloy
Bistrique polishing weld to fix bolt, old plate are removed, the work such as new plate installation and welding.The scheme that original Russian power station uses be
Reactor shaft directly lifts protection tube assembly, carries out transformation operation, and such a scheme total lever factor is 170.4h, collective dose
Reach 417.48man.mSv, anti-foreign matter+shielding dismounting number reaches 75 times.
The content of the invention
The technical problem that the utility model solves：
In view of the shortcomings of the prior art, it is flat to provide a kind of reactor protection tube assembly position adjustment work for the utility model
Platform, the transformation duration is effectively shortened, reduces personnel's radioactive dose.
The technical solution adopted in the utility model：
A kind of reactor protection tube assembly position adjustment workbench, including flat board body, angle steel, supporting leg, angle steel hang down
Face directly and be fixedly connected with the outer wall of protection pipe component inspection well, the horizontal plane top of angle steel is fixedly connected with flat board body, flat board
Side of the body away from protection pipe component inspection well is provided with supporting leg, and supporting leg bottom is bolted with delta-ring, can be passed through
Regulating bolt controls the length of each supporting leg, the final levelness for ensureing flat board.
The flat board body includes some blocks of steel plates, and some blocks of steel plates form flat board around protection pipe component inspection well and put down
Face.
The steel plate has a supporting leg.
The steel plate uses anti-skid design stainless-steel sheet.
The flat board body upper part can install guardrail as needed.
The beneficial effects of the utility model：
A kind of reactor protection tube assembly position adjustment workbench provided by the utility model, effectively shortens protection
The overhaul critical path time that tube assembly position adjustment takes, shortens the overhaul duration, and reduce overhaul collective radioactive dose.
Brief description of the drawings

Fig. 2 is flat board body construction schematic diagram；
In figure：1- flat boards body, 2- angle steel, 3- bolts, 4- supporting legs, 5- protection pipe component inspections well, 6- steel plates.
Embodiment
A kind of reactor protection tube assembly position provided by the utility model is adjusted with specific embodiment below in conjunction with the accompanying drawings
Full employment platform is described in further detail.
As shown in figure 1, a kind of reactor protection tube assembly position adjustment workbench provided by the utility model, including it is flat
Plate body 1, angle steel 2, bolt 3, supporting leg 4, the vertical plane of angle steel 2 are fixed by the outer wall of bolt and protection pipe component inspection well 5
Connection, the horizontal plane top of angle steel 2 are fixedly connected by bolt 3 with flat board body 1, and flat board body 1 is away from protection tube assembly inspection
The side for looking into well 5 is provided with supporting leg 4, the bottom of supporting leg 4 is bolted with delta-ring, can be controlled by regulating bolt each
The length of supporting leg 4, the final levelness for ensureing flat board
Workbench is integrally ridden upon between protection pipe shield components bucket and protection pipe component inspection well 5, wherein with protection
Gap between tube assembly inspection shaft 5 is designed as 10mm, between three plates adjacent with in-pile component inspection shaft and the inspection borehole wall
Gap be 50mm, this three side is not provided with guardrail, in addition while close to hanging basket inspection shaft position side on set 1.2 meters of high shields
Column.
As shown in Fig. 2 flat board body 1 includes 8 blocks of steel plates, 6,8 blocks of steel plates 6 forms flat board around protection pipe component inspection well 5
Plane.Every block of steel plate 6 has a supporting leg 4.Steel plate 6 is using anti-skid design stainless-steel sheet thick 5mm.
