Embodiment 1

[0035] This embodiment discloses a working platform for replacing the taphole of a converter, see figure 1 , which includes a platform body 2 and a support member, wherein:

[0036] The platform body 2 is set horizontally, and the platform body 2 is provided with a working through hole;

[0037] The supporting member includes an extension plate 4, a connecting plate 5, a brace plate 6 and a positioning plate. The extension plate 4 is arranged vertically. The lower end of the extension plate 4 is fixed on the end of the platform body 2 away from the converter platform 1, and the upper end of the extension plate 4 extends upwards. To the connecting plate 5 and fixedly connected with the connecting plate 5, the connecting plate 5 is arranged horizontally;

[0038] The positioning plate has a first positioning groove 36 with a cross-sectional shape of fan ring, the first positioning groove 36 is in clearance with the upper end of the converter platform 1, and the connecting plate...

Embodiment 2

[0042]On the basis of Embodiment 1, this embodiment also includes a first reinforcement member 71 and a second reinforcement member 72, the first end of the first reinforcement member 71 is connected to the platform body 2, and the opposite end of the first end of the reinforcement member is fixed On the extension board 4 , the first end of the second reinforcement member 72 is fixed to the extension board 4 , and the opposite end of the first end of the second reinforcement member 72 is fixed to the connecting board 5 .

[0043] This embodiment further includes a third reinforcement member 73 , the first end of the third reinforcement member 73 is fixed to the positioning plate, and the opposite end of the first end of the third reinforcement member 73 is fixed to the diagonal bracing plate 6 .

[0044] The extension plate 4, the connecting plate 5, and the slanting plate 6 have a large span, and the three parts and their joints are subject to relatively large shear stress. Th...

Embodiment 3

[0047] On the basis of Embodiment 1 or 2, the bottom of the platform body 2 has a second positioning groove 26 with an annular cross-sectional shape, and the second positioning groove 26 is in clearance fit with the upper end of the converter platform 1 . The bottom of the platform body 2 is provided with a second positioning groove 26 to be stuck on the upper end of the converter platform 1, so that the fixing of the platform body 2 is more stable, preventing the platform body 2 from moving radially along the converter platform 1, and further ensuring the safety of the operators. Personal safety.

Abstract

The invention discloses a platform used for changing a tap hole of a converter. The platform comprises a platform body and a supporting component; the platform body is horizontally arranged; an operation through hole is formed in the platform body; the supporting component comprises an extension plate, a connection plate, an oblique supporting plate and a positioning plate; the extension plate isvertically arranged; the lower end of the extension plate is fixed on one end, which is far away from the converter platform, of the platform body; the upper end of the extension plate extends upwardsto the connection plate and is fixedly connected with the connection plate; the connection plate is horizontally arranged; the positioning plate is provided with a first positioning groove with a fan-shaped cross section; the first positioning groove is in clearance fit with the upper end of the converter platform; and the connection plate is fixedly connected with the positioning plate through the oblique supporting plate. The platform has the beneficial effects that operation is safe; a crown block in a converter workshop is not occupied or not occupied continuously; assembly and disassembly of the converter platform are convenient; the platform is fixed stably and is not prone to overturning or moving after being assembled; and the platform is stable during an assembly or disassembly process, does not overturn or horizontally move, and only moves in the vertical direction.

Description

technical field [0001] The invention relates to the technical field of steelmaking, in particular to a platform for replacing a tap hole of a converter. Background technique [0002] The converter taphole needs to be replaced regularly, and the replacement of the taphole is done on a platform as high as 8.5m, which is very dangerous. When replacing the tap hole, the scrap steel bucket hoisted by the crane is used as the working platform, and the operator stands on the edge of the scrap steel bucket to perform operations such as filling refractory materials, correcting, welding and fixing the tapping hole liner. Occupying the crane during the operation not only affects the production efficiency of the workshop, but also lowers the safety factor of the scrap steel bucket hoisted by the crane as an operation platform. Contents of the invention [0003] The purpose of the present invention is to provide a converter replacement tapping hole platform, which is used to solve the...
