Description

HOSPITALS FOR DISMANTLING PLATE COLD 1THORIOR OR DEPLOYING FUTTER FURNACE OVENS To stabilize the platform during operation of the device, there are four spacer beams 8, one end of the spacer beam is fixed on the platform, and the second is extended to the stop in the case 7 and fixed in this position. Positions denote .9 - top flange 10 - plate refrigerator, 11 - lining - skullcap, 12 - pulley block. A mechanical manipulator 2 is installed on the platform, in a particular case, a hydraulic excavator, on the boom of which there is a percussion mechanism (in particular, a pneumatic hammer) with a working body 4 having a conical tip. When the platform 1 enters the furnace through the thistle flange 9, the cargo cantilever fingers 5 and the spreading beams 8 are in the folded position in order to reduce the platform 1. In order to fix the platform 1 inside the furnace in the working position, the fingers 5 will be folded and hinged suspended from the housing 7

The device works as follows

The working body 4 is introduced into the gap between the cooler 10 and the case 7 or between adjacent licorice (Fig. 3). Under the action of the shock mechanism 3, the working body 4 is driven into the gap. The conical tip of the working body 4 with the mapol angle at the apex of the cone provides for the amplification of the blows, under the influence of which the separation of the refrigerator 10 and its dismantling take place. At the same time there is a breaking of the skull 11.

The movement of the impact mechanism 3 in space, its direction into the gap and its pressing are carried out with the help of a manipulator 2.

After dismantling one or two rows of refrigerators, the platform 1 with the manipulator 2 is moved down to the new working position to dismantle the next row. For this, the platform 1 is suspended to the chain pulley 12, the spacer rays 8 are pushed in, and the console cargo fingers 5 are disconnected from the belts 6. After that, the platform 1 is lowered to the desired level, then fixed again on the strips 6 and the next row of refrigerators are dismantled.

After the dismantling of the coolers 1O has been completed, the proposed device is removed from the furnace upward through the top flange or downward through the opening in the furnace and shoulders.

Thanks to the conical shape of the tip of the working body 4, it can also be entered

Experimental-industrial testing of the efficiency and high performance of the device for demo-storage of hoop files.

The device is supposed to be used for capital repairs of blast furnaces 1 and 2, which will allow to reduce the duration of repairs by 2-3 days and free up 4OO-600 man-shifts on one repair with the usual effect of 25-35 thousand, py5.

To dismantle one row of dwellings in traditional ways we spend ..: from an average of 8-10 hours, and only on demons; refrigerators spend 2–4 days with a kanremosh-2 discharge, and 5–6 days with a 1-bit overhaul — 5-6 days, which is a significant part of the total amount of the furnace being repaired. The proposed device in 1974 was tested in the repair of blast furnaces (No. 2 Zaporozhstal and No. 8 of the plant named after us. 1
