Support meanss, it is to avoid reactor pressure vessel automatic checkout equipment is blocked to kingbolt screwed hole and seal groove, holds pressure
The inspection of device and kingbolt screwed hole, the cleaning inspection of seal groove can be carried out with the same period, shorten the unit maintenance time, improve economical
Benefit.
In order to solve the above technical problems, a kind of flange support of reactor pressure vessel automatic checkout equipment of the utility model
Device, the device includes flange switching part, four leads, four guide legs, and flange switching part is spliced into an annulus
Seat；Four leads are fixed positioned at the upper end of flange switching part, lead quartering annulus seat；Four guide legs, which are fixed, to be located at
The lower end of flange switching part.
It is fixed with the inside of described guide legs and holds out against cylinder and withstanding tight block, withstanding tight block, which is fixed on, holds out against cylinder inside.
Lead and guide legs are located at the upper and lower side of the same position of annulus seat.
Lead is circumferentially fixed feet, and feet is fixed on annulus seat.
Location-plate is installed, guide cylinder is coordinated by the abutment sleeve being connected on location-plate on annulus seat.
Flange switching part top is fixed with fence.
Advantageous effects of the present utility model are：By using the support meanss, it is to avoid inspection equipment is to screw thread
Blocking for hole and seal groove, has reached the effect for shortening the unit maintenance time, increasing economic efficiency；The support meanss are used first
When, shorten the unit maintenance time 24 hours, increase about 0.2397 hundred million degree of generated energy, create economic benefit more than 10,000,000 yuan.
