The anti-deformation tool used in hydrogenation reactor cylinder inboard wall weld deposit process at present, need to be welded and fixed with hydrogenation reactor cylindrical shell, its defect is: one, material needs to select the Cr-Mo heat resisting steel material identical with hydrogenation reactor cylindrical shell; Two, need to carry out the pre-heat treatment to welding position before welding, need after having welded to carry out stress-removal process; Three, the weld seam between anti-deformation tool and hydrogenation reactor cylindrical shell also needs polish round and smooth and carry out Surface testing; Four, when anti-deformation tool is removed, must be polished in the welding position with hydrogenation reactor cylindrical shell clean and do Surface testing.As can be seen here, the anti-deformation tool used in current hydrogenation reactor cylindrical shell weld deposit process, material selection requirement is high, use procedure is loaded down with trivial details, use cost is high.
Summary of the invention
The object of the invention is: provide a kind of easy to use, can the low hydrogenation reactor cylindrical shell built-up welding of Reusability, use cost time the anti-deformation tool that uses.
For achieving the above object, the technical solution used in the present invention is: the anti-deformation tool used during the built-up welding of hydrogenation reactor cylindrical shell, comprise at least two and hold round assembly, each assembly that holds round all is fixedly set in outside hydrogenation reactor cylindrical shell, and have at least two to hold round assembly to be fixedly set in the upper of hydrogenation reactor cylindrical shell respectively, lower two ends, each structure holding round assembly comprises: a pair mutually involutory semi-circular shape holds round ring, a pair semi-circular shape holds round ring mutual involutory rear formation annular and holds round ring, a pair semi-circular shape holds round on ring and is provided with locking device, a pair involutory semi-circular shape can be held round ring and be locked on hydrogenation reactor cylindrical shell by locking device.
Further, the anti-deformation tool used during aforesaid hydrogenation reactor cylindrical shell built-up welding, wherein, the structure of described locking device comprises: the upper and lower both sides holding round ring two ends in each semi-circular shape are fixedly installed locking connecting plate respectively, every block locking connecting plate all offers locking screw keyhole, and a pair mutually involutory semi-circular shape holds round the locking connecting plate one_to_one corresponding on ring and is provided with clamping screw in the locking screw keyhole on often corresponding a pair locking connecting plate.
Further, the anti-deformation tool used during aforesaid hydrogenation reactor cylindrical shell built-up welding, wherein, is welded to each other fixing between a pair locking connecting plate after clamping screw locking.
Further, the anti-deformation tool used during aforesaid hydrogenation reactor cylindrical shell built-up welding, wherein, described locking connecting plate is rectangular slab.
Further, the anti-deformation tool used during aforesaid hydrogenation reactor cylindrical shell built-up welding, wherein, comprises two and holds round assembly, and two hold round the upper/lower terminal that assembly is fixedly set in hydrogenation reactor cylindrical shell respectively.
Advantage of the present invention is: effectively can prevent hydrogenation reactor cylindrical shell in weld deposit process due to the effect such as high temperature and welding stress and produce distortion, thus ensure that the ovality of hydrogenation reactor cylindrical shell, decreasing the potential safety hazard of hydrogenation reactor cylindrical shell; In whole use procedure, hold round assembly and do not weld with hydrogenation reactor cylindrical shell, it is installed, uses and remove all very convenient, simple, quick.
Accompanying drawing explanation
The anti-deformation tool structural representation in a state of use that Fig. 1 uses when being hydrogenation reactor cylindrical shell built-up welding of the present invention.
Fig. 2 is the structural representation that Fig. 1 overlooks direction.
Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, the present invention is described in further detail.
As shown in Figure 1 and Figure 2, the anti-deformation tool used during the built-up welding of hydrogenation reactor cylindrical shell, comprise at least two and hold round assembly 1, each assembly 1 that holds round all is fixedly set in outer and have at least two the to hold round upper/lower terminal that assembly 1 is fixedly set in hydrogenation reactor cylindrical shell 2 respectively of hydrogenation reactor cylindrical shell 2.In the present embodiment, the anti-deformation tool used during the built-up welding of hydrogenation reactor cylindrical shell comprises two and holds round assembly 1, in actual use procedure, can arrange the suitable quantity holding round assembly 1 according to the height of hydrogenation reactor cylindrical shell 2.Each structure holding round assembly 1 comprises: a pair mutually involutory semi-circular shape holds round ring 11, a pair semi-circular shape holds round ring 11 mutual involutory rear formation annular and holds round ring, a pair semi-circular shape holds round on ring 11 and is provided with locking device, and a pair involutory semi-circular shape can be held round ring 11 and be locked on hydrogenation reactor cylindrical shell 2 by locking device.In the present embodiment, the structure of described locking device comprises: the upper and lower both sides holding round ring 11 two ends in each semi-circular shape are fixedly installed locking connecting plate 12 respectively, described locking connecting plate 12 is rectangular slab, every block locking connecting plate 12 all offers locking screw keyhole, and a pair mutually involutory semi-circular shape holds round locking connecting plate 12 one_to_one corresponding on ring 11 and is provided with clamping screw 121 in the locking screw keyhole on often corresponding a pair locking connecting plate 12.In order to prevent hydrogenation reactor cylindrical shell 2 further in weld deposit process, a pair semi-circular shape holds round ring 11 and mutually throws off due to high temperature and welding stress effect, is welded to each other fixing between a pair locking connecting plate 12 after the bolt 121 that is locked locking.Usually, wait hydrogenation reactor cylindrical shell 2 built-up welding to complete and after carrying out bulk heat treatmet, then the assembly 1 that holds round on hydrogenation reactor cylindrical shell 2 is removed.When dismounting holds round assembly 1, as long as cut open by the weld seam between a pair locking connecting plate 12, then unclamp all clamping screws 121, the semi-circular shape on such hydrogenation reactor cylindrical shell 2 holds round ring 11 and just can remove, very convenient.
