Detailed description of the invention
Introduce the technical solution of the utility model below in conjunction with the accompanying drawings.
This utility model HTGR Shaft bank built-in fitting welding auxiliary device includes inside at least three
Frock, as in Figure 2-4, internal frock 20 includes central canal 21, and on the outer wall of central canal 21, radial distribution has several
Dagger 22, in Fig. 2, on the outer wall of central canal 21, radial distribution has six support columns 22, and the quantity of support column 22 can basis
It is actually needed and is adjusted；Support column 22 is radially arranged along central canal 21, i.e. support column 22 radially extending along central canal 21,
Support column 22 is uniformly distributed on the outer wall of central canal 21.As it is shown on figure 3, support column 22 is provided with top away from one end of central canal 21
Silk 26, it is the arcuate structure identical with built-in fitting tube structure that the connection of this jackscrew 26 has gripper shoe 23, gripper shoe 23.
As shown in Figure 4, the quantity of internal frock 20 is three, in epimere shell ring 11, stage casing shell ring 12 and hypomere shell ring 13
An each internal frock 20, the gripper shoe 23 of the inside frock in epimere shell ring 11 and inwall of epimere shell ring 11 placed is fitted,
The gripper shoe 23 of the inside frock in stage casing shell ring 12 is fitted with the inwall of stage casing shell ring 12, the inside frock in hypomere shell ring 13
The inwall laminating of gripper shoe 23 and hypomere shell ring 13.The quantity of internal frock 20 is at least three so that epimere shell ring 11, in
Each at least internal frock 20 in section shell ring 12 and hypomere shell ring 13.
Preferably, as shown in Figure 2 and Figure 5, internal frock 20 also includes assisting support 33, and this auxiliary supports 33 and includes auxiliary
Support column 24, one end of this auxiliary support column 24 is fixed on central canal 21 outer wall, assists the other end of support column 24 to be provided with top
Silk 26, this jackscrew 26 connects auxiliary support plate 25, and auxiliary support plate 25 is identical with gripper shoe 23 structure.Auxiliary supports the number of 33
Amount is several.As shown in Figure 4, internal frock 20 also includes connecting plate 32, and the support column 22 of internal frock 20 is by this connection
Plate 32 connects, and so that three internal frocks 20 are connected as entirety, and the central canal 21 of these three internal frocks 20 is coaxial.
During use, as shown in Figure 4, the first step, in epimere shell ring 11, stage casing shell ring 12 and the hypomere shell ring 13 of built-in fitting
Place at least one internal frock 20 respectively, adjust the jackscrew 26 of internal frock 20, so that internal frock in epimere shell ring 11
Gripper shoe 23 is resisted against on the inwall of epimere shell ring 11, forms epimere shell ring 11 and supports；Internal frock in stage casing shell ring 12
Gripper shoe 23 is resisted against on the inwall of stage casing shell ring 12, forms stage casing shell ring 12 and supports；Internal frock in hypomere shell ring 13
Gripper shoe 23 is resisted against on the inwall of hypomere shell ring 13, forms hypomere shell ring 12 and supports.Epimere shell ring 11, stage casing shell ring 12 and
Hypomere shell ring 13 is all to be processed by welding procedure, after having welded, will internal frock 20 be positioned over epimere shell ring 11,
In stage casing shell ring 12 and hypomere shell ring 13, support so that epimere shell ring 11, stage casing shell ring 12 and hypomere shell ring 13 are formed.
Second step, adjusts jackscrew 26, to adjust gripper shoe 23 to epimere shell ring 11, stage casing shell ring 12 and hypomere shell ring 13
Support force, and then adjust epimere shell ring 11, stage casing shell ring 12 and the circularity of hypomere shell ring 13, make epimere shell ring 11, stage casing shell ring
12 and the circularity of hypomere shell ring 13 meet design requirement.Due to the supporting role of internal frock 20, epimere shell ring 11, stage casing shell ring
12 and hypomere shell ring 13 can keep adjust after circularity, be not susceptible to deformation.As shown in Figure 2 and Figure 4, in this step, example
As for epimere shell ring 11, when the region between two support columns 22 adjacent on epimere shell ring 11 is also required to adjust circularity,
Then auxiliary support column 24 can be fixed on the outer wall of central canal 21, auxiliary support plate 25 is resisted against and needs to adjust circularity
Region, screws the jackscrew 26 on auxiliary support column 24 to adjust epimere shell ring 11 circularity.Use in identical method also adjustable
The circularity in the region between two support columns 22 adjacent on section shell ring 12 and hypomere shell ring 13.
3rd step, is grouping welding, during group pair, on the one hand to epimere shell ring 11, stage casing shell ring 12 and hypomere shell ring 13
Epimere shell ring 11, stage casing shell ring 12 and the respective circularity of hypomere shell ring 13 to meet the requirements, on the other hand will by epimere shell ring 11,
Stage casing shell ring 12 and hypomere shell ring 13 adjust to coaxially.In this step, epimere shell ring is adjusted further by internal frock 20
11, stage casing shell ring 12 and the circularity of hypomere shell ring 13, due in second step to epimere shell ring 11, stage casing shell ring 12 and hypomere
The circularity of shell ring 13 has carried out adjusting and the supporting role of internal frock 20, so in this step, technical staff can be quick
The circularity of each shell ring is adjusted to meeting the requirements by ground, simultaneously because internal frock 20 to epimere shell ring 11, stage casing shell ring 12 and under
Section shell ring 13 support, epimere shell ring 11, stage casing shell ring 12 and hypomere shell ring 13 be not susceptible to deformation, technical staff can facilitate
Rapidly each shell ring is adjusted to coaxially, it is to avoid group to during repeatedly adjustment, saved the improvement time, shortened work
Phase.Internal frock 20 can also be greatly reduced the deformation after epimere shell ring 11, stage casing shell ring 12 and hypomere shell ring 13 assembly welding.Center
Pipe 21 is the structure of hollow, the inner space of central canal 21 be used for the instrument such as total powerstation release epimere shell ring 11, in
Section shell ring 12 and the centrage of hypomere shell ring 13.
As shown in Figure 4, it is preferable that at epimere shell ring 11, stage casing shell ring 12 and hypomere shell ring 13 groups to front, first by epimere cylinder
Inside frock 20 in joint 11, stage casing shell ring 12 and hypomere shell ring 13 is connected as entirety, and the central canal 21 of internal frock 20 is same
Axle, such as, can use connecting plate 32 to connect, the support column 22 of neighbouring two internal frocks 20 with by neighbouring
Two internal frocks 20 be connected as an entirety, use same method, three internal frocks 20 be connected as an entirety,
And the central canal 21 of these three internal frocks 20 is coaxial, during such welding, is conducive to epimere shell ring 11, stage casing shell ring 12
Adjust to coaxially with hypomere shell ring 13.
In the installation process of built-in fitting 15, during hoisting transportation built-in fitting 15 and built-in fitting 15 install after-pouring in place mix
During solidifying soil, internal frock 20 is all prevented from built-in fitting 15 and deforms.
