  . . .

The invention relates to ferrous metallurgy, in particular to the mechanization of the installation of refractory blocks of lining of a blast furnace for major repairs, chimneys and similar structures.

The aim of the invention is to expand the operational capabilities of the device and increase the performance of the device.

FIG. 1 schematically shows the proposed device fei blast furnace; FIG. 2 shows a device for mounting the refractory blocks of the blast furnace lining, a general view, in FIG. 3 shows section A-A in FIG. 2; in fig. 4 shows a section BB in FIG. 2

The device contains an annular monorail 1 attached under the spring repair platform 2 (overlapping) inside the envelope of the multi-link hinge belts 3, two electric hoists 4 with movement mechanisms by driving carriages 5, which are pivotally connected by rods 6 to the intermediate carriage 7.

The hooks 8 of the electric hoists 4 are suspended from a yoke 9, which is located on the chord of the annular monorail 1 at a distance from the center of the suspended repair platform 2, more than half the length of the refractory lining block; This distance is fixed by rods 6 connecting the carriages 5 of the electric hoists 4 to the intermediate carriage 7. Traverse 9 has a mechanism 10 for moving the mobile cargo boom 11. The traverse 9 is made in the form of a beam of a box-section with two rollers 12 , between which are the supporting shelves of the movable cargo boom 11 .. The movable cargo boom 11 has the ability to extend in both directions the yoke 9 At the end of the mobile cargo boom 11 a fixed block 13 of the cargo polyspast is built in, and zu outside the sectional crosspiece 9 to the mobile truck, the boom 11 lift mechanism 14 is attached hook suspension. 15 cargo polyspast.

With the implementation of the multi-light technology of repairing the blast furnace, the suspension repair platform 2 is located below the suspension repair platform 2.

Through the roller table 17, inside the blast furnace 18, refractory blocks 19 are fed.

The device works as follows.

5 way.

After filing the refractory block 19 on the roller table k7 inside the shaft of the blast furnace 18, the hook suspension 15 of the cargo polyspast is lowered

10 through the opening in the suspension repair platform 16 and the refractory block 19 is hooked onto the hook suspension 15. The lifting mechanism 14 lifts the refractory block 19 to

15 levels of mounted row. Manipulir installed on. an annular monorail 1 under the overhead repair platform 2 by the mechanisms of movement of the carriages 5 of the electric hoists 4,

20 interconnected by the rods 6 and the intermediate carriage 7, and the movement mechanism 10 of the movable cargo boom 11, which moves along the rollers 12, are refractory

25, the block 19 is guided inside the dimension of the multi-link hinge tapes 3 to the necessary place around the circumference of the furnace and is set in the design position.

3Q Upon completion of the installation of the refractory blocks 19 of one row of lining, the yoke 9 with the movable cargo boom 11 is lifted by the electric hoist 4 to mount the blocks of the next row.

The line connecting the hooks of hooks 8 of two electric hoists 4 and coinciding with the longitudinal axis of the crosshead 9 is located along the chord of the ring m / noro and is separated from the axis of the blast furnace 18 at a distance greater than half the length of the refractory block 19. The length of the cross member 9 is slightly less than neither the light between the two diametrically opposed belts 3. These features, despite the fact that the length of the movable cargo boom 11 is substantially longer than the length of the traverse 9 and the clear distance between the opposite belts 3, make it possible to carry out t devices in plan and deliver the refractory block 19 with a supply roller conveyor 17 at any place okra Shost furnace.

55 This is possible because at the approach of the rear extended end of the cargo boom 11 to the hinge belt 3, the opposite (working) part

.31

The boom, on which the neodvigging unit 13 is mounted, is in the sector between the hinge belts 3, the extension of the cargo boom 11 to the side of the working end is provided. a passage of the back of the device past the hinge belt 3. Then, the movable boom 11 shifts again toward the rear end, ensuring the passage of the front end with the refractory

block 19 past the nearest cargo belt 3, etc.

The use of the proposed device for the installation of refractory blocks 5 of the lining of a blast furnace allows for the transportation of refractory blocks to any place of masonry and acceptance of refractory blocks anywhere in the blast furnace shaft, and the same 10 increase in productivity.
