Description

The invention relates to metallurgy, in particular, to the repair of the lining of metallurgical ladles.

A machine for lining metallurgical ladles is known, comprising a portal carrying a hollow rod, at the end of which a support plate is fastened with a rotation mechanism of a sanding head, forming a formwork and a packing radius measuring mechanism [G].

However, in this machine, when packing a conical lining, the drive control of the mechanism for changing the packing radius, i.e. radial displacement of the sanding head, is made by the operator visually.

It is also known a device for automatic lining of fork bays, comprising a frame, a movable ₂₀ vertical rod with a lining device and a segment pattern, a mechanism for radial movement of the lining device and a follower.

The installation contains a portal 1 with a drive 2 of its movement. Portal 1 is supported by platform 3 on supports 4 slip. In the opening of the platform 3, a vertical telescopic bar is installed, consisting of an outer 5 and an inner 6 bar. On top of the portal 1 is mounted platform 3 displacement actuator 7, on which the actuator 8 polispastnoy system 9. The rods 5 and 6 carry sochlenen- nye ³⁵ between a vertical chute 10 which serve for guiding; lining mass. An overpass 11 with a bunker 12 for lining weight and a disk feeder ⁴⁰ 13 is installed on the poruale 1, and on the platform 3 a “conveyor-. ter 14 connecting the feeder 13 with troughs 10. On the inner rod 6 through the support-turntable 15 is fixed frame 16, the rotary drive 17 Torah Ko ⁴⁵ housed in the flange rod 6, the guides 18 of the frame 16 is installed lining device configured as a carriage 19, carrying a sandblasting head 20 with a drive 21, a transport ⁵⁰ porter 22 and a segment pattern 23.

Drive 24 radial movement of the truck 19 is placed on the frame 16.

An integral part of the installation is a tracking device intended for automatic control. In the process of packing the drive 24 of the movement of the trolley 19 with the sand-bed gear 916084 4

dexterous 20, required to obtain a given bucket lining profile.

On the inner rod 6, the ruler 25 is hingedly mounted, corresponding to 5 inclinations of the working surface of the footers. A bucket, for example, a conical profile, provided with a roller holder 26, pivotally mounted on its upper part and connected to the vertical on the “0” guide 27, mounted on the platform 3. The Copy Line 25 is kinematically connected to the control mechanism of the radial movement of the “Airfoil Device” by an end of the clock roller 28 connected to a spring-loaded rail 29 mounted on the guide 30 and connected via gear 31 to the selsyn 32. The control mechanism of the radial displacement of the lining device is attached en to the lower plane of the platform 3. Selsin 32 is an integral element of the electric control system for the drive 24 of the carriage 25 of the trolley 19. This system also includes the selsyn 33 mounted on the frame 16 and through gear rack and pinion associated with the mechanism of radial movement of the carriage 19.

30 The lower end of the copier ruler 25 is connected with the radial correction mechanism of the path of movement of the lining device, designed to automatically control the drive 24 to move the trolley 19 with the sanding head 20 necessary to perform the specified bucket cross-sectional contour (elliptical, oval).

The radial correction mechanism includes a lever 34 pivotally mounted on the flange of the inner rod 6, one arm of which is pivotally connected to the ruler 25, the other θ is provided with a roller 35 interacting with. adjustable copier 36 mounted on the upper part of the frame 16 of the lining device. Adjustment of the copier 36 is made by screw mechanisms 37 located along the perimeter of the copier and fixed on the frame 16 of the lining device.

The installation works as follows

In the initial position, the telescopic rod is in the folded state with the lining device raised to the upper position. Por916084 4

The talent 1 with the aid of the drive 2 travels to the bucket 38 prepared for repair. The telescopic rod with a lining device is lowered by the drive 8 into the bucket 38 and centering with 5 using the drive 7 movement of the platform 3 ι drive 2 of the portal 1 movement. at a distance of 20-40 mm from the bottom of the bucket. Drive 24 move "0 of the trolley 19 with the sandblasting head 20 and the segment pattern 23 sets the gaps between the last and the wall of the bucket 38, equal to the thickness of the butt-bottom in the lower part of the bucket. Include 15 drives 17 rotation of the lining device, sand-measuring head 20, conveyors 22 and 14, disk feeder 13.

Lining mass from the hopper 12 20

supplied by the Feeder 13 to the conveyor 14 and further along the grooves 10 is sent to the conveyor belt 22, feeding it into the sand-jet head 20, from which the flow of compacted mass 25 packs is ejected into the gap between the bucket wall 38 and the segment pattern 23.

After filling the first layer of the lining, include a drive 8 lifting rod with a lining device,

Copy ruler 25 for lifting the lining device makes a plane-parallel movement due to its articulation with the roller holder 26 moving along the vertical guide _35. At the same time, the ruler, interacting with the roller 28 of the control mechanism for the radial movement of the lining device, moves the spring-loaded rail _40, 29 which rotates at a certain angle gear 31 on the shaft 32 of the synchro, a mismatch occurs in the electrical control system of radial movement futero- novel developing lips ₄₅ oystva, whereby the control pulse is supplied to the actuator 24 which moves the carriage 19 with the head 20 to peskometnoy until the toothed rack ₅ svya- θ zannaya the trolley 19 does not turn synchro gear shaft 33 by a corresponding angle and, most, restore balance in the control system. Thus produced aetomati ^m cal drive control 24. The gland liner elliptical and open furrows buckets tracker provides a mechanism by radial

Correction movement of the lining device, acting as follows:

The adjustable copier 36 with a plate of screw mechanisms 37 is given a shape similar to the contour of the middle cross section of the bucket, while the large copy of the copier must be aligned with the axis of rotation of the rotor of the sanding head

20. Before packing by turning the lining unit c. using the actuator 17 orient the position of the copier 36. relative to the roller 35 ·

During the rotation of the lining device by the actuator 17, the copier 36 rotates with it, acting through the roller 35 of the two arms of the lever 34 to the copier. ruler 25, by changing its angle of inclination, thereby introducing a correction into the trajectory of movement of the lining device, as a result of which a given contour is obtained in the cross section of the bucket lining.

Thus, due to the articulation of a vertical copying ruler with a horizontal adjustable cam, a total control pulse is obtained to automatically regulate the drive of the radial movement of the lining device, which provides the specified bucket lining formula.

At the end of the packing of the lining of the bucket walls, the installation mechanisms are disconnected in the following sequence: a disk feeder 13, conveyors 14 and 22, a drive 21 of a shot-measuring head 20 and a drive 17 of rotation of the lining device. After that, the actuator 8 telescopic rod together with the lining device is lifted to the extreme upper position, and the actuator 2 sets off the installation to its original position. Ladle 38 is transported by a crank for drying the lining. Installation is ready to repair the lining of the next bucket.
