Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
A converter transformer riser split kit, comprising: a transport pod and a transport deck. FIG. 1a is a front view of a transportation cover according to an embodiment of the present invention; fig. 1b is a bottom view of the transportation cover according to the embodiment of the present invention.
The transportation cover includes: the circular base plate 1, the transportation cover cylinder wall 2, the flange plate 3 and the hanging plate 4, wherein the size of the flange plate 3 is matched with the size of an upper flange of the valve a lifting seat middle section, the diameter of the circular base plate 1 and the transportation cover cylinder wall 2 is slightly smaller than that of the flange plate 3, and the height of the transportation cover cylinder wall 2 is matched with the height of a wire outlet device of the valve a lifting seat middle section, which is extended out of the middle section. The wall 2 of the transportation cover barrel is welded on the circular bottom plate 1 to form a circular cavity for accommodating a wire outlet device of the middle section of the lifting seat of the valve a; the flange 3 is welded on the transport cover cylinder wall 2, a pair of hanging plates 4 are welded at opposite positions on the circumferential edge of the flange 3, and the hanging plates 4 are flat plates with round holes in the middle, so that the transport cover is convenient to hang.
The circular bottom plate 1, the transportation cover cylinder wall 2, the flange 3 and the hanger plate 4 are welded together to form a transportation cover integral structure, and the flange 3 is a component of the transportation cover. Since special tools (such as a shrink band and plastic foam filling, which are common) are used for reliably fixing the wire outlet device and the valve side lead wire in the valve a lifting seat, no additional fixing structure needs to be added to the transportation cover. The transportation cover is connected with the upper flange of the middle section of the lifting seat of the valve a by the flange plate 3 through bolts. The main reason for using the transportation cover instead of the transportation cover plate is that the wire outlet device is higher than the valve a to lift the flange on the middle section of the seat.
The size of the circular transportation cover plate is matched with that of the upper section of the valve a lifting seat, the diameter of the circular transportation cover plate is slightly larger than that of the upper section of the valve a lifting seat, and bolt holes, the positions of which are matched with those of bolt holes of a lower flange of the upper section of the valve a lifting seat, are formed in the transportation cover plate; the transportation cover plate is provided with a sealing groove, and the diameter of the sealing groove is matched with that of the upper section of the lifting seat of the valve a, so that the sealing performance of the lifting seat of the upper section of the lifting seat of the valve a in the transportation process is ensured. A pair of hook-shaped handles are welded at opposite positions on the circumferential edge of the circular transportation cover plate. Fig. 2 is a schematic structural diagram of a transportation cover plate according to an embodiment of the present invention.
The transportation cover plate is made of a whole steel plate by adopting a machining method. Because the valve a only contains a current transformer in the lifting seat upper section part and does not have a wire outlet device, the valve a only needs to be connected with the bolt hole on the transportation cover plate through the lower flange bolt hole of the lifting seat upper section by the bolt. The sealing groove on the transportation cover plate is used for ensuring the sealing of the upper section of the valve a during the transportation process of the lifting seat, and two handles (two hooks) on the transportation cover plate are arranged for facilitating the carrying and the installation of an operator on the transportation cover plate.
In the embodiment of the invention, the material of the transportation cover and the transportation cover plate is preferably common carbon steel.
A method for disassembling a lifting seat of a converter transformer comprises the following steps:
step 1, dismantling accessories of the converter transformer after the test is completed, and only reserving a valve side lifting seat part, wherein the method comprises the following steps: valve a raises the seat and valve b raises the seat. Fig. 3 is a schematic structural view of the converter transformer body with the accessories removed. As can be seen from fig. 3, the upper section of the valve a lifting seat is significantly higher than the converter transformer body, beyond the transport height limit.
And 2, because the lifting seat at the valve side is arranged, the lifting seat of the valve a exceeds the limit of the transportation height during the transportation of the converter transformer, and at the moment, the upper section part of the lifting seat of the valve a needs to be detached.
And 3, because the outlet device in the lifting seat of the valve a extends out of the flange of the lifting seat of the middle section of the lifting seat of the valve a by a certain size, designing a transportation cover according to the size of the cylinder wall of the lifting seat and the size of the flange, installing the designed transportation cover on the middle section of the lifting seat of the valve a, fixing the outlet device in the lifting seat of the valve a and a valve side lead reliably, and avoiding damage in the transportation process. Fig. 4 is a schematic view of a transformer body with a transportation cover according to an embodiment of the present invention.
And 4, designing a transportation cover plate according to the structural characteristics of the dismantled upper section lifting seat lower flange, and processing a sealing groove on the transportation cover plate to ensure the sealing property of the upper section lifting seat in the transportation process.
And 5, connecting the detached valve a lifting seat upper section lifting seat with the bolt hole of the transportation cover plate through a lower flange bolt hole of the valve a lifting seat upper section lifting seat by using a bolt, and sealing the sealing groove of the transportation cover plate by using a sealing gasket to ensure the sealing property of the upper section lifting seat. Fig. 5 is a schematic view of the valve a lifting seat upper section of the embodiment of the invention with a transportation cover plate 5.
And 6, safely transporting the transformer body and the upper section of the valve a lifting seat to a construction site, and completing rapid assembly on the site.
The transportation cover plate and the transportation cover which need to be designed in the split transportation mode have simple structures and are convenient to process. The split transportation mode saves a large amount of time for dismantling the valve a lifting seat, the valve b lifting seat and installing the lifting seat on site, improves the installation efficiency, reduces the safety risk in the process of dismantling and installing the outlet device again, and reduces the transportation cost.
Finally, it is to be noted that: the above examples are only specific embodiments of the present invention, and are not intended to limit the technical solutions of the present invention, and the scope of the present invention is not limited thereto. Those skilled in the art will understand that: any person skilled in the art can modify or easily conceive the technical solutions described in the foregoing embodiments or equivalent substitutes for some technical features within the technical scope of the present disclosure; such modifications, changes or substitutions do not depart from the spirit and scope of the embodiments of the present invention, and they should be construed as being included therein.
