Description

one

This invention relates to the steel industry.

A device for servicing a blast furnace slag furnace, containing its column, a rotational drive, a cantilever beam with guides, in which a carriage with a body of a working tool fixed to it, is located is known.

The known machine does not allow the mapping tools to be used when performing maintenance operations on the case, since the tool is rigidly connected to the carriage. The provided fixation of the machine with a hook to the bracket on the casing of the blast furnace does not provide the accuracy required for the slag tap hole because of the gap between the bracket and the hook.

Performing the rotation drive as a separate gearbox mounted on the column does not allow its use in the area of the slag tap.

The purpose of the invention is to carry out maintenance operations for the drip and case and reduce the size of the device.

In the proposed device, the carriage is hingedly connected to the water-cooled body of the air hammer, which provides mannula tools when servicing the case, and is equipped with a pressure cup

for rigid fixation of pneumatic impact when opening letkpp. In addition, the rotation drive is integrated into the column and provided with a clip-ring gripper, which allows the tool to be accurately fixed along the axis of the notch.

FIG. 1 shows a general view of a device for opening the slag tap of a blast furnace and servicing its case; in fig. 2 - view

along arrow A in FIG. one; in fig. 3 - connection of the body (in which the air hammer is placed) with the carriage; in fig. 4 - section B - B in FIG. 2; in fig. 5 - wedge ring grip in the plan.

The collar 1 is mounted with a cantilever bracket 2 with guides 3. Between the guides, there is a carriage 4 with rollers 5, which is connected by a valuable gear 6 with a driving sprocket 7 and a tensioning sprocket 8. A sliding drive 9 is fitted with a cantilever bracket 9. A coupling 10 connects the drive 9 with a leading sprocket 7. A pneumatic hammer 11 with a working tool 12 is hinged on the carriage.

NoMenien pneumatic hammer into the water-cooled body 13 (Fig. 3), connected to the carriage through the spherical hinge 14 with the pressure cup 15. The fixing device is equipped with a wedge-ring storon 16,

associated with the pneumatic cylinder 17 on the fixed part of the column. The pins 18 of the stopper are connected to the half-rings 19. The eccentric 20 is used to clamp the gripper, which is connected with the pneumatic cylinder 17 by the lever 21. The device rotates around the axis of the column 1 with the rotary drive integrated in the column (Fig. 4) until the working tool 12 is aligned with the axis slag tap In this position, it is fixed by the blade-ring stopper 16. The non-biasing drive 9 (Fig. 2) rotates the drive sprocket 7 through the clutch 10, which drives the valuable gear 6, and the carriage 4 moves with it. The drive 9 provides the carriage forwards at different speeds m idle and working stroke. At the moment of contact of the working tool 12 (Fig. 1) with a slag crust during punching or with a working mass during packing and destruction of the case, the hammer is activated 11. After the carriage returns to its original position, the device can be rotated back to an angle of 180 °, thereby the slag trench zone is emptied. When punching the slag notch presser cup 15 (Fig. 3), the sling is pressed to the water-cooled body 13. In this case, the working tool 12 is rigidly connected to the carriage 4. When the sheath is destroyed and its packing the presser glass is retracted from the water-cooled body using a thread, and the hinge 14 allows the operator to manipulate the tool with the handle. The hole is cut in the case when the hammer is disconnected 11. Object of the invention A device for servicing the slag tap of a blast furnace, containing a column with a rotary drive and a cantilever beam fixed on it with guides in which the carriage is located that, in order to carry out maintenance operations on the channel and casing and to reduce the overall dimensions of the device, the carriage is connected to the housing of the working tools drive by a ball joint, and the rotation drive is Olona built into it and is provided with a wedge-shaped annular stopper clamp shoes are connected with an eccentric clamp.
