Description
Technical field
The utility model relates to presurized water reactor technical field, is specifically related to a kind of presurized water reactor in-pile component detector of lifting device.
Background technology
As shown in Figure 1, 2, presurized water reactor formula nuclear reactor in-pile component suspender, its manufacturing accuracy is high, after completing, assembling needs the significant dimensions of workpiece to detect, because workpiece is huge, and use have particular/special requirement, need to make the special instruments of inspection it is detected, also do not have at present specific pick-up unit.
In-pile component suspender 1 install for reactor and cold-refueling during lift compacting part and the hanging basket parts of in-pile component.While installation first, adjust tripod pull bar 2, use special lifting appliance, make workpiece self-equilibrating, ensure that W facial plane degree, must be taking W face as benchmark when each cold-refueling lifting within 0.5mm.When reactor cold-refueling, suspender hangs out compacting part 3 in pressure vessel, is then held in place together on the compacting part storage rack 4 of refuelling pool storage area.In the time of pressure vessel inservice inspection, this suspender also needs the hanging basket parts 5 of unstowing after reactor core assembly to hang out in pressure vessel, is then held in place together on the hanging basket parts storage rack 6 of refuelling pool storage area.Suspender is according to different action needs, and depended on pressure container guidepost, pool wall guidepost 7 or compacting part storage rack guidepost lead respectively.During reactor operation, on this hanger storage and compacting part storage rack.So the orienting sleeve size of suspender need to be reviewed, ensure with this precision lifting.3 lifting columns are processed according to in-pile component suspender processing template, when lifting, need to connect in-pile component, and size is important.
Summary of the invention
For above-mentioned technical matters, the utility model provides a kind of presurized water reactor in-pile component detector of lifting device, and the detection that completes suspender that it can simple and fast detects good stability, and precision is high, can increase work efficiency.
Realize the technical solution of the utility model as follows:
Presurized water reactor in-pile component detector of lifting device, comprise the base with horizontal supporting face, on base, on horizontal supporting face, distribute and be provided with three detection rest pads, three upper surfaces of detecting rest pad have respectively the carrying plane in same level, be provided with in the both sides of base horizontal supporting face and there is the detection cover that detects through hole, on base horizontal supporting face, be provided with three simulated blocks with rotary jack, the flatness of the carrying plane of described detection piece and the end face of simulated block is less than 0.1mm.
Adopt such scheme, adjusted in assembly yard, made to detect the carrying plane of piece and the flatness of simulated block end face is less than 0.1mm, ensured like this flatness of whole device, then base has been fixed; When the driving in-pile component suspender of slinging, slowly move to pick-up unit top, make the guidepost on suspender aim at the detection through hole that detection puts, driving starts slow decreasing, until being seated one to one, the back-up block on suspender bottom detects on rest pad, now by the handwheel of lifting column on operation suspender, lifting column bottom is entered in simulated block socket, and make it rotate, lock, now just complete the testing process of suspender, and by detecting W facial plane degree, to confirm the overall assembly precision of suspender; The utility model can simple and fast the detection that completes suspender, detect good stability, precision is high, can increase work efficiency.
Further, described rotary jack is arranged at the middle part of simulated block, is provided with two-layer spacing layer in rotary jack, in each spacing layer, is arranged and is formed by multiple limited blocks interval, and the distance between two-layer limited block equates and remains on same axis.Like this lifting column bottom can precession between two-layer limited block, play the effect that lifting column bottom is detected.
Further, the distance between the spacing layer in described both sides is between 20mm-30mm.The one, can insert for lifting column lower end, the 2nd, can provide certain space for the rotation of lifting column lower end.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Referring to Fig. 3-5, presurized water reactor in-pile component detector of lifting device, comprise the base 2 with horizontal supporting face 1, on base, on horizontal supporting face, distribute and be provided with three detection rest pads 3, three upper surfaces of detecting rest pad have respectively the carrying plane 4 in same level, be provided with in the both sides of base horizontal supporting face and there is the detection cover 6 that detects through hole 5, on base horizontal supporting face, be provided with three simulated blocks 8 with rotary jack 7, the flatness that detects the carrying plane of piece and the end face of simulated block is less than 0.1mm.Certain rest pad, detection here overlapped, the quantity of simulated block can arrange according to the quantity of corresponding component on suspender, not says to be exactly only to arrange two, three.
Rotary jack is arranged at the middle part of simulated block, is provided with two-layer spacing layer in rotary jack, in each spacing layer, is arranged and is formed by multiple limited blocks 9 intervals, and the distance 10 between two-layer limited block equates and remains on same axis.Distance between the spacing layer in both sides is between 20mm-30mm.In concrete enforcement, limited block coboundary in the spacing layer in upper strata is arranged to inclined-plane 11, being convenient to like this lifting column lower end enters in rotary jack, the angle forming between this inclined-plane and simulated block sagittal plane can be 50 °-70 °, can form guiding smoothly to lifting column lower end like this, and can be due to angle too small, after lifting column withstands on inclined-plane, cannot realize guide effect, or angle is excessive, causes lifting column lower end not enter smoothly in rotary jack.
In addition, in order to make this device adapt to the testing requirement of different size suspender, on base, offer strip through-hole, above-mentioned rest pad, detect on cover, simulated block and be fixed with and insert limited block in corresponding strip through-hole, and be fixedly installed latch segment at rest pad, detection cover, simulated block perisporium, after rest pad, detection cover, simulated block move into place in corresponding strip through-hole, by adopting clamping screw or screw through latch segment, rest pad, detection cover, simulated block to be locked in to fixed position, thereby can to meet the testing requirement to different size suspender.
Referring to Fig. 6, this pick-up unit also comprises a sleeve 12, before detection, before suspender lifting column declines, owing to having certain gap between lifting column 13 and supporting annular distance 14, it is between lifting column and supporting annular distance, in order to limit rocking in lifting column decline process that sleeve inserts in this gap, effectively ensure with this precision that lifting column declines, be convenient to detect the processing dimension of lifting column.The outer wall of sleeve pipe can be fixed with outside piece, by lock-screw or bolt, outside piece is locked on sustained ring 15, and sleeve just can not decline in the lump in the time that lifting column declines like this.
