Description
Technical field
The present invention relates to hanging device field, particularly relate to and a kind ofly forge the suspender of AP1000 main nuclear power pipeline in cold section and hot arc solution heat treatment process and fast hoisting method.
Background technology
Forging AP1000 main nuclear power pipeline is first production in the world, cold section that wherein forges AP1000 main nuclear power pipeline is irregular pipe fitting with hot arc, surface strength under the condition of high temperature is very low, the lifting position of profiling tongs is difficult to control the center of gravity predetermined, pipeline is laid particular stress on, cause local to occur severe nick, cause pipeline to be scrapped.Technology for Heating Processing requires that heat treatment fire door opens to the handling of pipe fitting one integral piece and submerges in water and must control in 3 minutes in addition, and the time is very short, requires supporting suspender to mount rapidly and handling, and can not reduce the surface quality of pipeline.Existing suspender cannot meet AP1000 main nuclear power pipeline heat treatment related request: 1) high temperature come out of the stove and submerge water to forging entirety within 3 minutes; 2) hot stage main pipeline does not allow the metallic contact with other material; 3) consider unpredictable problem on deformation, any position of main pipeline, has not allowed any cut, to prevent because distortion causes surplus not enough.
Summary of the invention
The object of this invention is to provide a kind of suspender and fast hoisting method of forging AP1000 main nuclear power pipeline, for the requirement to handling in forging AP1000 main nuclear power pipeline solution heat treatment process, reach in heat treatment process and improve pipeline and to come out of the stove speed, and strictly control pipeline surface quality and deflection object.
For achieving the above object, the present invention is achieved through the following technical solutions:
The suspender of forging AP1000 main nuclear power pipeline, comprise hanging beam, yoke plate and profiling suspension hook, be arranged with spacing tooth plate at the top at the two ends of hanging beam, profiling suspension hook is hung below the middle part of hanging beam by chain, and two yoke plates are hung below the spacing tooth plate at hanging beam two ends respectively by chain symmetry; Described yoke plate is arc and two ends are porose, and the length of yoke plate is 0.75 ~ 0.8 of the girth of lifting place pipeline, and the coupler body of yoke plate both sides and profiling suspension hook installs traction steel wire respectively.The top of described spacing tooth plate is provided with 6 ~ 10 grooves perpendicular to its length direction along its length.
The quick handling method of forging AP1000 main nuclear power pipeline, when Nuclear piping carries out solution treatment, concrete handling is carried out in the steps below:
1) before shove charge, according to the concrete size of pipeline, the chain sling length of predetermined yoke plate and the concrete hanging position of profiling suspension hook;
2) covered with the sheet steel of pipeline with material the contact site of profiling suspension hook and both sides yoke plate and pipeline, when avoiding coming out of the stove, main nuclear power pipeline directly contacts with suspension hook, yoke plate;
3) respectively traction steel wire is installed in yoke plate both sides and profiling suspension hook rear portion, when determining to come out of the stove, operates the personnel positions of traction steel wire simultaneously;
4) after shove charge, first lift by crane in advance pipeline, according to lifting by crane result in advance, determine overhead traveling crane and spreader position, traction steel wire operator erect-position, each post personnel all prepare at assigned address;
5), when coming out of the stove, each post personnel, by predetermined scheme operation, make pipeline come out of the stove by predetermined scheme fast hoisting and proceed in pond within 3 minutes, complete solution treatment.
Compared with prior art, the invention has the beneficial effects as follows:
The inventive method is applicable to the solid solution stage of cold section of AP1000 nuclear power Nuclear power plant main pipeline and hot arc, ensure that entering the water time from oven door opening to workpiece is no more than 3 minutes, the technological requirement of all pipe surface quality and deflection can be met, the operating standard that the present invention can be used as the solution heat treatment of nuclear power forging steel pipe is promoted, and has the advantage of convenient and reliable operation.
