The invention relates to ferrous metallurgy, in particular to equipment for the installation of refrigerators and refractory blocks.

The purpose of the invention is to expand the sizes of serviced furnaces, reduce the operational loads on the boom, reduce installation time and improve work safety.

Figure 1 shows the device, a general view; figure 2 - manipulator (dash-dotted line shows the working position); in FIG. 3, view A in FIG. 2 (the dotted line shows the position of the boom when the refrigerator is seized); Fig. 4 illustrates the installation of a refrigerator in a lodgment with its fixation with hydrocline; FIG. 5 shows the installation of a refrigerator on the furnace casing; Fig. 6 shows the unlocking of the refrigerator and the output of the patterns from the gaps between the refrigerators.

A device for mounting elements, a blast furnace, mainly refrigerators and refractory blocks, will consist of a running turntable 1 supported by rollers 2 on a monorail

3, mounted on the furnace shell. On the turntable 1 placed lifting hydraulic mechanisms

4, which, by means of carrier belts 5, are connected to a hanging platform 6 on which a telescopic boom 7 is installed, comprising stationary and retractable booms 8 and 9. The stationary boom 8 is supported by a trolley 11 through two hydraulic cylinders 10 and is able to move along the rail 12 The stationary boom 8 is hingedly mounted in the support 13 with the possibility of rotation in the vertical and horizontal planes.

The sliding boom 9 has at its end a head 14, to which the gripper 15 is fastened, on which the hydrolin 16 is mounted with the possibility of adjustment, the vertical template 17, the horizontal template 18, and also the pusher 19.

Site 6 is equipped with a power supply. viznaya guide 20, on which the stop 21 is located and at the end - barge 22 with adjustable stop 23. Guide 20 is fixed to the platform by latch 24. On guide 20 a trolley 25 is installed with a bed 26 and a drive 27 of its vertical movement. On the sides of the rail 20, there are two telescopic walkways 28 for accommodating

installers who perform the exact installation and fastening of the cold to the furnace casing. Platform 6 is provided with lodgments 29, in which backup coolers 30 are installed. The device is controlled from the console 31 mounted on the fixed boom 8.

The device works as follows.

In order to install refrigerators of the first row, U-shaped metal sheets are welded to the furnace casing, they tamp the end surfaces of the refrigerator. Before installation of the next row of refrigerators, the stop 23 of the shoe 22 is installed so that when it stops at the end of the refrigerator of an installed row, the axis of the guide 20 is aligned in the same plane with the axis of the refrigerator of the row to be installed.

Ridroclin 16 is installed according to the size between the axes of the holes for the fasteners of the refrigerator. Vertical and horizontal patterns 17 and 18 of the grip 15 are set so as to ensure the alignment of the axes of the hydro-lines 16 and the holes for the fasteners of the refrigerator.

The boom 8 is lowered so that the pattern 18 ups into the shoe 22. The boom 9 is pulled out, while the mold 18, interacting with the shoe 22, pushes the guide 20 by the amount required for this furnace size,

The manipulation mechanisms of rotation and lifting of the platform 6 and the extension of the boom 9, the shoe 22 is placed on the upper surface of the described metal sheets. When this stop 23 is included in the gap between the sheets, simulating the gap between the refrigerator. After that, the guide 20 is fixed with respect to the pad 6 by the clamp 24. At the same time, the operational loads are perceived by the cart 25 and a part of them is transmitted through the guide 20 to the furnace casing, which reduces the loads on the telescopic boom 7 and pad 6.

Raise the boom 8 so that the template 18 is at the stop 21. Reset the boom 9 to its original position.and remove the cart 25 from the bed 26, turn it together with the cart 11 onto the rail 12 until the vertical template 17 stops against the end surface of the refrigerator 30, installed in the ciu- oNd of the lodgements 29. After that, lift station 9 up to the stop of the horizontal template 18 at the lower end of the holo. Dilnika 30, Pull out the boom 9 until it seizes the grip 15 in the refrigerator. At the same time, Tidroclin 16 is inserted into two holes for the heads of the refrigerator mounting bolts. By turning on the hydraulic glands drive 16, the storage bottle 30 is fixed on the grip 15.

The presence of backup refrigerators 30 at the site eliminates the dependence of the operation of attaching the refrigerator to the vat 15 from the operation of delivering it from the storage location, which reduces downtime, and installing the refrigerator 30 in the cradle 29 simplifies its attachment to the gripper 15, makes this operation safe and in general, also reduces installation time.

Next, the boom 8 is rotated until its axis is aligned with the axis of the guide 20. The boom 9 is pulled out and placed on the bed 26 of the carriage 25, at the same time the rods of the hydraulic cylinders 10 are retracted. place and fasten with two bolts to the furnace casing. At the same time, templates 17 and 18 provide the necessary design gaps between adjacent refrigerators and, thus, eliminate the manual operation of installing refrigerators in the design position, reducing the repair time of the furnace and increasing the safety of work.

Turning on the hydroclinic drive

1 and the pad 6 suspended from it at an angle necessary for the installation of the next refrigerator, and all the described operations are repeated. This eliminates the need to bypass the chains, there are no dead zones, which also shortens the repair time.

After installation of the first row of refrigerators, the platform 6 is raised by hydraulic mechanisms 4 to the height required for the installation of the next row. When installing this and Btex of subsequent rows, the end surfaces of the previous series of refrigerators serve as the base for the installation.

Similarly to the described, installation of refractory blocks can be carried out.

The application of the invention allows to expand the size of the furnaces being serviced, reduce the operational loads on the boom and the platform, reduce the time for installation of refrigerators and increase the safety of work.
