Description
Technical field
The utility model relates to post-irradiation examination field, particularly, relates to a kind of COD and advises assistant assembleing and fixing device.
Background technology
The fracture toughness change of reactor pressure vessel material is the important indicator of irradiation effect monitoring, is also the technical basis of safety assessment and life-span management.Current trend adopts CT sample fracture toughness test to determine the radiation embrittlement situation of RPV material.Because fracture toughness test is very high to the requirement of test macro precision, therefore must install COD rule additional on CT sample, the loaded line displacement of COD rule for measuring CT sample.
When carrying out the fracture toughness test of non-irradiated sample, be generally free-hand rule by COD and be installed on sample.For the fracture toughness test of sample after irradiation, due to the radioactivity of sample, testing equipment must be arranged on to be had in the hot cell of function of shielding, and uses mechanical arm to carry out various operation.Due to the limitation of Robot actions, simple rely on standard machinery hand in hot cell cannot realize being installed between COD rule with 0.5T-CT sample, therefore must develop special purpose device in hot cell and carry out auxiliary manipulator and complete being installed between COD rule with 0.5T-CT sample.
The domestic research about fracture toughness test is at present limited to non-irradiated sample substantially, does not have to advise assistant assembleing and fixing device for the COD used for reference.Outer core developed country of state has carried out the correlation test technical research in this field, but due to the difference of extensometer structure and mechanical arm, must develop the COD that applicable existing hot cell condition uses and advise assistant assembleing and fixing device.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of lifting work efficiency, and the COD reducing operating personnel's radioactive dose advises assistant assembleing and fixing device.This device coordinates mechanical arm conventional in hot cell can complete being installed between COD rule and sample smoothly.
The technical scheme in the invention for solving the above technical problem is:
A kind of COD advises assistant assembleing and fixing device, comprise loading frame, the top of loading frame is provided with sample and is installed groove, the bottom of loading frame is provided with COD and advises the groove that is installed, be installed groove and COD of sample advises and the loading frame that is installed between groove is provided with the passage that two of advising for accommodating COD advise arm, passage two leads to be installed groove and COD of sample advises the groove that is installed, thus the rule arm of COD rule stretches into sample from passage and is installed in groove, loading frame is also provided with pressure is inwardly carried out pushing up in the outsides from two rule arms pre-compressing device to the rule arm of two in passage.
Described pre-compressing device is two points of screw rods being arranged at passage both sides, loading frame is provided with the tapped through hole matched with screw rod, two screw rods are each passed through corresponding tapped through hole and stretch in passage, and screw rod is perpendicular to passage and to the rule arm formation extruding that the COD of homonymy advises in the process screwing in passage.
Described sample be installed groove and the passage of groove, COD rule that be installed is the groove of open front, the be installed bottom surface of groove, left side wall and right side wall of sample surrounds the cell body closed with specimen configuration matching size, and by bottom surface, test is supported, thus realize fixing sample; The be installed bottom surface of groove, left side wall and right side wall of COD rule surrounds the cell body of to advise physical dimension with COD and matching, and by bottom surface, COD rule are supported, thus realize fixing COD, passage runs through the be installed bottom surface of groove and COD rule of sample and to be installed the end face of groove, thus is communicated be installed groove and COD rule of sample and is installed groove.
Described being positioned at loading frame that COD rule are installed on front side of groove is provided with one and COD rule is pressed in COD rule and is installed the latch of groove, loading frame is provided with the jack of Fixed latches.
The sample groove that is installed has upper shed, is convenient to sample and enters sample from upper load and be installed in groove.
The outer end of two screw rods is all provided with operating grip, thus facilitates screwing of screw rod.
Be provided with a limited block for auxiliary pre-pressing in described passage, it is between two COD rule rule arms, when two COD rule rule arms are extruded into close to limited block, illustrates that two COD rule rule arms arrive restraining position.
Be provided with base bottom described loading frame, loading frame is fixedly arranged on this base, and base quality is comparatively large, guarantees device in operation stable and firmly.
During use, by mechanical arm, COD rule being loaded COD rule is installed in groove, then two screw rods are rotated by mechanical arm, the end of screw rod is screwed in passage, and then two screw rods inwardly extrude the rule arm of corresponding side respectively from the outside of two rule arms respectively, reduce COD and advise two distances of advising between arm, when the COD distances of advising between two rule arms are less than the bayonet socket width of sample, stop the screw-in of two screw rods; By mechanical arm, sample being loaded sample is installed in groove, and now, the end of two rule arms is sitting at the bayonet socket inside of sample; Two screw rods are screwed out by mechanical arm, two rule arms move laterally, and final two rule arms are by sample bumping post, continue to screw out screw rod until screw rod no longer contacts rule arm, bounces now between two rule arms are all born by sample, this completes COD rule and being installed of sample.
To sum up, the beneficial effects of the utility model are:
What complete that fracture toughness test must realize that sample and COD advise is installed, COD rule are a kind of accurate length varying value surveying instruments, in test for the displacement variable of test sample crackle mouth position, after irradiation, sample has strong radioactivity, can not hand operation, the mechanical arm in hot cell must be used.Only using mechanical arm to complete, sample and COD advise is installed, because the bounce that COD advises arm is very large, mechanical arm cannot apply so large power, and COD rule arm is most advanced and sophisticated very little with the operating space of sample bayonet socket link position, certain location must be had just to complete, use mechanical arm also cannot realize being installed.
And the utility model adopts mechanical arm and COD rule assistant assembleing and fixing device to match, complete being installed between COD rule with sample smoothly, solve the problem that is installed between COD rule with sample, improve work efficiency, decrease operating personnel's radioactive dose.
