Described reinforcement elements is made up of diagonal ligament beam and block.
For solving problems of the prior art, the present invention can also adopt following technical scheme to implement, and a kind of platform building method for slippage furnace shell in blast furnace restricted clearance, comprises the steps:
The first, above fire door, build the first platform, the second platform;
The second, by the first installation of slide track at distance ring-shaped edge 2m place, fire door both sides, its one end is welded with the first platform edges, and the other end stretches out first platform edges 2 ~ 3m, and is welded with the first platform surface by four groups of reinforcement unit;
3rd, by the second installation of slide track on the second platform, and strengthen unit and the second platform welding by four groups;
4th, furnace shell is placed on the second slideway by the first hanging device, then by traction type equipment, furnace shell is placed on the first slideway, find furnace shell and fire door position accurately;
5th, by the second hanging device, furnace shell is sling, after removing the first slideway, furnace shell is put into fire door, complete building of furnace shell slippage.
The invention has the beneficial effects as follows: the first, the present invention by arrange at table two groups of slideways make over the work of heavy, time-consuming furnace shell slippage become easily, quick.The second, the present invention reduces construction area, saves human input, reduces production cost, and there is quality guarantor's duration.3rd, the present invention is rational in infrastructure, build simple, easy to use, is applicable to promoting.

Embodiment
In order to make the present invention more easily be understood, below in conjunction with embodiment shown in the drawings, technical scheme of the present invention is described in detail.
As shown in Figure 1, the invention provides a kind of platform for slippage furnace shell in blast furnace restricted clearance, comprise fire door 1, first platform 2, second platform 3, on described fire door, 1 is provided with the first platform 2, described first platform 1 is connected with the second platform 2, described first platform 1 is provided with the first slideway 4, described second platform 3 is provided with the second slideway 5.
Described first slideway 4 is arranged on apart from ring-shaped edge 2m place, described fire door 1 both sides, and its one end and described first platform 2 edge conjunction, the other end stretches out described first platform 2 edge 2 ~ 3m.
Described first slideway logical 4 is crossed four groups of reinforcement elements 6 and is connected with described first platform 2.Described second slideway 5 is connected with described second platform 3 by four groups of reinforcement elements 6.Described reinforcement elements 6 is made up of diagonal ligament beam and block.One end that described first slideway 4 stretches out table 1 apart from described second slideway 5 between 1 ~ 2m.Described first slideway 4, second slideway 5 all adopts H profile steel assembly welding, and the first slideway 4 is used as final support furnace shell 10; Second slideway 5 as transition slideway, for by furnace shell 10 from outer platform slide transitional to blast furnace foundation overhead.
As shown in Figure 2, invention can also adopt following technical scheme to implement, and a kind of platform building method for slippage furnace shell in blast furnace restricted clearance, comprises the steps:
The first, on table 1, build the first platform 2, second platform 3;
The second, be arranged on by the first slideway 4 apart from ring-shaped edge 2m place, fire door 1 both sides, its one end is welded with the first platform 2 edge, and the other end stretches out first platform 2 edge 2 ~ 3m, and strengthens unit 6 and the first platform 2 surface-welding by four groups;
3rd, the second slideway 5 is arranged on the second platform 3, and strengthens unit 6 and the second platform welding by four groups;
