Embodiment 1

[0047] A ring-shaped hanging platform for hot blast furnace shell installation

[0048] see now Figure 1 ~ Figure 3 , figure 1 It is the elevation view of the annular platform of the embodiment of the present invention, figure 2 It is a schematic diagram of the hanging ear structure of the embodiment of the present invention, image 3 It is the plan view of the annular platform of the embodiment of the present invention. As shown in the figure, the hanging lug 4 of the annular hanging platform installed on the hot blast furnace shell is made of steel plate, and is in the shape of an arc, 200mm long, 80mm wide, and 6mm thick, and is welded and fixed along the circumference of the annular furnace shell On the outer wall of the annular furnace shell, the hanging lug is 1.2m away from the upper opening of the first belt furnace shell, and the circumferential distance between the hanging lugs is 1.5m.

[0049] The tripod 5 is made of ∠50×5mm angle steel, with a width of 1m an...

Embodiment 2

[0054] An installation method of a ring-shaped hanging platform for installation on the outer wall of a hot blast stove shell

[0055] An installation method for an annular hanging platform installed on the outer wall of a hot blast stove shell, characterized in that it includes the following steps:

[0056] a. After the first belt furnace shell 1 is assembled and welded on the ground, the prefabricated hanging lug 4 is welded and fixed on the outer wall of the furnace shell along the circumference of the furnace shell. The distance between the hanging lug and the upper opening of the first belt furnace shell 1 is 1.2m. The spacing is 1.5m.

[0057] b. Insert the hooks of the prefabricated tripod 5 into the hanging lugs 4, arrange them along the circumference of the first belt furnace shell 1 with a distance of 1.5m, and weld and fix the lower end legs on the furnace shell.

[0058] c. Lay steel springboards 8 above the two adjacent tripods 5, and tie the ends of the tripods ...

Embodiment 3

[0066] An installation method of a ring-shaped hanging platform for installation on the inner wall of a hot blast stove shell

[0067] In this embodiment, except that the hanging lug 4 is welded and fixed on the inner wall of the annular furnace shell, the tripod 5 is arranged along the circumference of the inner wall of the first belt furnace shell 1, and cooperates with the railing 6, the safety net 7, the steel springboard 8 and the steel ladder 9 in the annular furnace shell. Except that the ring-shaped hanging platform is set on the inner wall, all the others are the same as in Embodiment 2.

Abstract

The invention discloses an annular hanging platform for mounting a stove shell of a hot-blast stove. The annular hanging platform comprises a first belt stove shell (1), a second belt stove shell (3), hanging lugs (4), tripods (5), a railing (6), a safety net (7), a steel jumping plate (8) and a steel ladder stand (9), and is characterized in that the first belt stove shell (1) and the second belt stove shell (3) are annular stove shells spliced by multiple circular arc steel plates and having the same diameter; the hanging lugs (4) are produced by steel plates, shaped like circular arc omegas and fixedly welded on the outer walls of the annular stove shells along the peripheries of the annular stove shells; the tripods (5) are right triangle brackets made of angle steels; the steel jumping plate (8) is laid on the adjacent two tripods (5); and the steel ladder stand (9) is formed by welding steps (10) between two parallel longitudinal beams (11). The annular hanging platform has the advantages of simple structure, easy machining, convenience for mounting and dismounting, repeated use, quickened construction progress and shortened construction period.

Description

technical field [0001] The invention relates to a hot blast stove installation platform, in particular to a ring-shaped hanging platform for installing a hot blast stove shell and an installation and removal method. Background technique [0002] With the rapid development of my country's economy, blast furnace ironmaking technology has progressed very fast, and the hot blast stoves that provide heat sources are developing in the direction of large-scale, diversified and high-efficiency. During the installation process of the hot blast stove shell, it needs to be assembled from bottom to top ring by ring. At this time, a construction operation platform needs to be built. There are two kinds of conventional construction platforms: full-scale scaffolding platform and hanging chain platform. The scaffolding platform of the whole hall is erected layer by layer from bottom to top. Using this method of construction requires the use of a large amount of materials, which is costly a...
