The upper racks (3) are respectively in mesh connection through a spherical surface and spherical hinge regulator (4). The platform (2) is formed by circular rings in radial connection. The supporting leg sets (1) are only disposed at the center and two sides of the platform (2). The tool rack for assembling and conveying nuclear power containment vessel domes is advantageous in that deformation of domes during assembling and conveying can be effectively controlled; assembling and conveying can be simplified; dismounting is convenient and cost is saved.
Description
Technical field
The utility model relates to the nuclear power field, particularly a kind of Nuclear Safety shell cover head assembly unit and transport frock support.
Background technology
The generation Ⅲ nuclear power technology of at present extensive use is that non-active compressed water reactor nuclear power technical security is high, and operation cost is low.It can utilize modular technology in process of construction, the bull Implement Construction of going forward side by side has greatly shortened the nuclear power generating sets construction period.From put into operation, load former expect begin generating, the fastest needs 36 months, the saving of construction cost aspect is with the obvious advantage.Cover head (dome) assembly unit and transportation are important steps in the building course of whole generation Ⅲ nuclear power station.40 meters of general cover head (dome) diameters, 760 tons of high 11.5 meters, gross weights, by 4 kinds of specifications, 64 blocks of arc plates are spliced.Owing to will dock assembly welding with the Fourth Ring cylindrical shell after its lifting, therefore need to be strict with the Deformation control of cover head (dome).This just requires special installation to guarantee that cover head (dome) keeps Stability Analysis of Structures in assembly unit and transportation, do not deform.
Summary of the invention
In order to guarantee that Nuclear Safety shell cover head (dome) keeps Stability Analysis of Structures in assembly unit and transportation, do not deform, the utility model provides a kind of Nuclear Safety shell cover head assembly unit and transport frock support.
The purpose of this utility model is to reach by following measures: a kind of Nuclear Safety shell cover head assembly unit and transport frock support are provided, it is characterized in that, described Nuclear Safety shell cover head assembly unit and transport frock support comprise: some supporting legs, platform, some upper bracket and some sphere ball pivot adjusters; Described supporting leg is installed on the platform base plane, and is fixedly connected with platform, and the distribution of supporting leg can reserve transit passage for flat bed transport vehicle, can effectively utilize the original built-in fitting in place again, no longer newly increases installation of embedded parts; Be installed on the platform after the netted connection of described upper bracket, support designs according to cover head (dome) splicing situation, cover head (dome) is spliced by the arc plate of four circle different sizes, therefore the design of support is comprised of four annular elements, one circle arc plate of each unit supports cover head (dome), the end floor beam angle is decided with the sphere setting-out of cover head (dome) on the unit, fixes with the oblique pull angle steel between four ring elements of support, all connects with bolt between all shaped steel; Described ball pivot adjuster is installed on the upper end floor beam of the every unit of support, its requirement that distributes is that four to six ball pivot adjusters are arranged under every block of arc plate of cover head (dome), the bulb of adjuster is wanted support top end socket (dome) arc plate inwall, realizes accurately regulating the location.
Wherein, described platform is the basis by rice word beam, and the annular i beam that connects eight circle different-diameters has formed whole circular platform, and the basis of support is seated in the upper cover plate of landing beam, and supporting leg is connected with the lower cover of landing beam, and all types of attachment are bolt and connect.
Beneficial effect: the utility model can effectively be controlled the distortion in cover head (dome) assembly unit and the transportation, for cover head (dome) provides powerful guarantee with effective docking of cylindrical shell, saved a large amount of time for the assembly unit of on-the-spot cover head (dome) in addition; Be easy to transportation, bolted form easy accessibility can reuse the saving cost in addition.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
Referring to figs. 1 through 5, in the present embodiment, the cover head assembly unit of this Nuclear Safety shell and transport frock support are comprised of supporting leg, platform, upper bracket and sphere ball pivot adjuster.Supporting leg: supporting leg has supported the weight of all frocks of platform top and cover head (dome) and penetration piece thereof, and the distribution of supporting leg is also for transporting the passage that provides necessary that enters of operating mode flat car in addition.
(a) platform: be in the structure between supporting leg and the upper bracket.It is main the connection and primary structure member in cover head (dome) the assembly unit process.In the transportation operating mode, flat car admission passage lifting platform and upper component thereof reach the purpose of removing the supporting leg smooth transport.
(b) upper bracket: suit the upper bracket of cover head (dome) cambered surface design, adopt netted connection, make assembly unit process and transportation safer, stable.Bolt fastening structure form between support, can reuse transportation and easy accessibility, has saved great amount of cost.
(c) sphere ball pivot adjuster: because cover head (dome) is by 4 kinds of specifications, 64 blocks of arc plates are spliced.The setting of sphere ball pivot adjuster, both can regulate because the position height that the support foozle produces is poor, guaranteeing has four contact points to contact fully below every block of arc plate, also can by the sphere enlarge active surface without corner angle, prevent from causing scraping of mother metal to undermine distortion.The setting in 338 ball pivot joints also can be played the effect of flexible modulation when the arc plate docks.
Splicing: the supporting leg with tooling bracket is installed in on-the-spot original footing position first, is fixedly connected with supporting leg after the platform and integrally splicing, secondly splices from inside to outside upper bracket.After tooling bracket manufacturing and splicing were finished, enchashment field one basic point utilized total powerstation and transit that the sphere ball pivot is carried out height and diametric(al) location, after adjusting work is finished, can carry out the splicing assembly welding work of cover head (dome) arc plate.
Transportation: four dollies utilize the passage between the supporting leg to enter platform below assigned address, utilize the common lifting platform of self hydraulic system,, remove the connecting bolt between supporting leg and platform, thereby make the two separation dismounting supporting leg when be critical stressed.Simultaneously pressure release of flat car is placed on the flat car platform.Together with support, cover head (dome) is transported to the appointment Hoisting Position.
Above content is the further description of the present invention being done in conjunction with optimal technical scheme, can not assert that the implementation of invention only limits to these explanations.Concerning the general technical staff of the technical field of the invention, under the prerequisite that does not break away from design of the present invention, can also make simple deduction and replacement, all should be considered as protection scope of the present invention.
