Summary of the invention

The purpose of this utility model be to provide a kind of simple and practical, can lift by crane fast to be arranged in State of Blast Furnace very useful in the suspender of lifting furnace shell and cooling stave.

To achieve these goals, the technical solution of the utility model is: a kind of State of Blast Furnace that is arranged in is very useful in the suspender of lifting furnace shell and cooling stave, its difference is: it includes cross beam, connects secondary beam, annular single track, electric block, cross beam is connected on the platform girder of blast furnace furnace roof, cross beam is connected with the connection secondary beam, cross beam be connected secondary beam below be connected with annular single track, the annular single track be steel I-beam and its diameter less than furnace throat band furnace shell diameter, electric block cooperates and is installed on the annular single track and can moves along annular single track track.

Described annular single track takes bolt to be connected with cross beam, annular single track be connected secondary beam and take welding process to connect.

Described cross beam be connected secondary beam and take welding fixing.

Described electric block is 10 tons a electric block, and its erecting bed number is no less than 2.

The utility model utilizes original furnace shell frame that one group of cross beam is set, annular single track is installed under cross beam, on annular single track, electric block is installed, electric block can be rotated on annular single track to be moved, utilizing electric block to carry out lifting work, so both avoid the use loop wheel machine, can conveniently adjust the lifting angle again; Whole apparatus structure is simple and practical, and is with low cost.

Embodiment

In order to understand the utility model better, below in conjunction with embodiment and accompanying drawing the technical solution of the utility model is described further, referring to Fig. 1 to Fig. 6:

Very useful by a kind of State of Blast Furnace that is arranged in that the utility model is implemented in the suspender of lifting furnace shell and cooling stave, it includes cross beam 2, cross beam 2 adopts the material of HM600 * 300 * 12 * 20, for firm welding to prevent because of lifting causes displacement, cross beam 2 is welded on original State of Blast Furnace roof panel girder 1.Cross beam 2 is the groined type shape, is welded with the identical connection secondary beam 5 of material between four flanks, and the below that connects secondary beam 5 and cross beam 2 is connected with annular single track 4.Connect secondary beam 5 and be that square is outer to be cut in annular single track 4 and to be attached thereto, effective tie point with annular single track 4 increases to 12 like this, eight of annular single track 4 and cross beam 2 add four that are connected secondary beam 5 and annular single track 4, thereby improved the reliability that annular single track 4 connects, make stressed more evenly, structure is more stable.Each beam assembly unit joint mode of connection all adopts welding process to connect with reference to shaped steel joint standard.

Annular single track 4 adopts the ring-like single track of I40b, and it is connected the employing bolt hole with cross beam 2 be φ 23.5mm, φ 22 Bolt Connection, annular single track 4 be connected secondary beam 5 and take the welding process connection.Annular single track 4 is according to the design of furnace throat band furnace shell 3 diameter, and its diameter must be less than furnace throat band furnace shell 3 diameters.Cooperate on the annular single track 4 10 tons electric block 6 is installed, electric block 6 can move along annular single track 4 tracks, to adjust the lifting angle, the erecting bed number of electric block 6 is no less than 2, selects for use one or two electric blocks 6 to cooperate wireline to lift according to monolithic furnace shell 8 hoisting capacities and monolithic physical dimension size.Cooling stave 9 need use cooling stave ejector 10 when installing, cooling stave ejector 10 is positioned on the hanging scaffold 11, after the electric block lifting of earlier hanging scaffold 11 usefulness being used in pairs promotes fixedly decoupling device in place, with electric hoist cooling stave 9 is winched to specified location, use cooling stave ejector 10 ejection cooling staves 9 then, cooling stave 9 is against on the blast furnace furnace wall.The hanger structure that the utility model provides is simple, and simple operation is with low cost, and lifting is reliable, can satisfy and can't use the construction requirement that lifts by crane furnace shell 8 or cooling stave 9 under the loop wheel machine situation.

Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalence of being done according to the utility model claim changes, and still belongs to protection domain of the present utility model.
