Description
Technical field
The invention belongs to shear field, and in particular to a kind of spentnuclear fuel associated component underwater hydraulic shearing dress
Put.
Background technology
Spentnuclear fuel associated component includes C＆P systems, Neutron source assembly, burnable poison assembly and resistance plug group
Part.After every first operation circulation of unit, there are 66 weary burnable poison assemblies and 2 primary neutron source components,
It is stored in Spent Fuel Pool in fuel assembly or private adapter, occupies more than 100 spentnuclear fuel compartment
Frame.As the Spent Fuel Pool useful space can use the reduction year by year of screen work quantity, useless associated component is frequently moved
Position, is received for fresh fuel, and RCCA is checked and overhaul discharge pond positioning is affected greatly, based on weary
Cost and lack of water pond Optimum utilization are transported after fuel, in time by useless associated component cluster shear treatment, is stored classifiedly
Advantageously account for the not enough problem of Nuclear Power Station's Exhausted Fuels storage screen work storage capacity.
Spentnuclear fuel associated component underwater hydraulic shear constitution mainly realizes that single rod chipless is sheared safely under water.
Because the reason for radiation protection, shear constitution needs 4 meters of deep completions under water during work, and people is in sink deck
Bank remote operation.Shear constitution must shear cluster against spentnuclear fuel associated component suspension bracket base plate, prevent
Clip to silver and plug with molten metal cadmium pellet or boron glass pipe, discharge radgas.24 rods on component suspension bracket base plate
, in circumferential diverging arrangement, gap is smaller between cluster for beam, and minimum spacing is that 15mm and 24 cluster needs
All shearings.Control rod cluster need to shear position diameter about 9.7mm, and resistance stopper beam need to shear section diameter
About 7mm, material is all stainless steel 304.In shear history, cutter and its clamping device must not damage spring knife
Fragment is produced, or damages component boron glass pipe etc..This process needs larger shearing force, general pneumatic execution
Element is difficult to provide so big shearing force under the conditions of such small size, therefore is realized using hydraulic system
The shearing of spentnuclear fuel associated component cluster.To ensure the water quality of reactor pit, in whole processing procedure not
There must be other liquid leakages to pollute pond, therefore the hydraulic pressure with hydraulic oil as working media of routine should not be used to fill
Put.
It is put two kinds of forms, i.e. vertical display and level nothing but and puts during shearing spentnuclear fuel associated component.Examine
If it is poor to consider cutter its force mechanism form of crossing feed, therefore by spentnuclear fuel associated component horizontal positioned, cutter
Move up and down realization shearing.Either lateral shear or vertical shearing will overcome component cluster circumferentially to launch
Arrangement, cluster spacing is small, and cutter is difficult to enter, shears the difficulties such as residual root influence feed.
The content of the invention
It is an object of the invention to propose a kind of spentnuclear fuel associated component underwater hydraulic shear, screen work is improved
Space availability ratio, lifts operating efficiency.
Technical scheme is as follows：A kind of spentnuclear fuel associated component underwater hydraulic shear, including cut
Crop, hydraulic cylinder, fixed stock, wherein hydraulic cylinder are bolted on fixed stock, and cutting head connects
It is connected on hydraulic cylinder；Cutting head includes ledger-plate, body, cutting blade, guide post, wherein transition disc, mistake
Scale upper end is connected on hydraulic cylinder, and lower end is connected with body, and crossing in scale has through hole；Body is rectangle,
Circular arc being provided with thereon and being oriented to groove, guide post is installed on body circular arc and is oriented in groove, and guide post is cylindrical,
Guide post upper end is connected with hydraulic cylinder piston rod, and cutting blade is arranged on guide post lower end, cutting blade by bolt
It is rectangle, cutting blade is located at the top of ledger-plate；Ledger-plate is arranged on body lower part, stationary knife by bolt
Piece cutter head setting thickness is less than spentnuclear fuel associated component cluster spacing.
The cutting head is bolted on hydraulic cylinder.
The scale upper end of crossing is bolt-connected on hydraulic cylinder.
The guide post upper end is connected by male and female header structure with hydraulic cylinder piston rod.
The cutting blade and ledger-plate form cutting edge positional distance and are less than 25mm with ledger-plate front position.
A step surface is contained in the body upper end, and step surface spacing between ledger-plate is related more than spentnuclear fuel
Component height, this spacing can cause that body avoids the spentnuclear fuel associated component cluster residual position sheared.
Remarkable result of the invention is：Can realize that spentnuclear fuel associated component cluster is sheared, it is ensured that cut through
The safety of spentnuclear fuel associated component in journey, reduces spentnuclear fuel associated component and takes screen work space and useless relevant group
Part moves the work of position, lifts operating efficiency.
