At the ring-shaped edge 2m of both sides, its one end is connected with described first platform edges, the other end stretch out described first platform edges 2～
3m。
Described reinforcement elements is made up of bearing diagonal beam and block.
For solving problems of the prior art, the present invention can also adopt the following technical scheme that and implement, a kind of for
In blast furnace restricted clearance, the platform building method of sliding furnace shell, comprises the steps:
First, above fire door, build the first platform, the second platform；
Second, by the first installation of slide track at the ring-shaped edge 2m of fire door both sides, its one end is welded with the first platform edges, another
End stretches out the first platform edges 2～3m, and is welded with the first platform surface by four groups of reinforcement units；
3rd, by the second installation of slide track on the second platform, and by four groups of reinforcement units and the second platform welding；
4th, furnace shell is placed on the second slideway by the first hanging device, then by pulling equipment, furnace shell is placed on first
On 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 furnace shell
Building of sliding.
The invention has the beneficial effects as follows: first, the present invention makes over heavy, expense by arranging two groups of slideways at table
Time the work of furnace shell sliding become light, quick.Second, the present invention reduces construction area, saves manpower and throws
Entering, reduce production cost, there is quality guarantor's duration.3rd, present configuration is reasonable, it is simple to build, user
Just, it is suitable for promoting.

Detailed description of the invention
It is understood to make the present invention be easier to, below in conjunction with the embodiment shown in the drawings skill to the present invention
Art scheme is described in detail.
As it is shown in figure 1, the present invention provides a kind of for the platform of sliding furnace shell in blast furnace restricted clearance, including fire door 1, first
Platform the 2, second platform 3, on described fire door, 1 is provided with the first platform 2, and described first platform 1 connects 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 at described fire door 1 both sides ring-shaped edge 2m, its one end and described first platform 2 edge
Connecting, the other end stretches out described first platform 2 edge 2～3m.
Described first slideway leads to 4 four groups of reinforcement elements 6 excessively and is connected with described first platform 2.Described second slideway 5 is by four groups
Reinforcement elements 6 is connected with described second platform 3.Described reinforcement elements 6 is made up of bearing diagonal beam and block.Described
One slideway 4 stretches out one end of table 1 apart from described second slideway 5 about between 1～2m.Described first slideway 4,
Two slideways 5 all use H profile steel assembly welding, and the first slideway 4 supports used by furnace shell 10 as final；
Second slideway 5 as transition slideway, for by furnace shell 10 from outer platform slide transitional to blast furnace foundation overhead.
As in figure 2 it is shown, invention can also adopt the following technical scheme that and implement, a kind of for sliding in blast furnace restricted clearance
Move the platform building method of furnace shell, comprise the steps:
The first, on table 1, build first platform the 2, second platform 3；
Second, the first slideway 4 is arranged at the ring-shaped edge 2m of fire door 1 both sides, its one end is welded with the first platform 2 edge,
The other end stretches out the first platform 2 edge 2～3m, and by four groups of reinforcement units 6 and the first platform 2 surface soldered；
