Description

(54) INSTALLATION FOR LAYING METALLURGIC BUCKETS

The aim of the invention is to reduce the size of the installation.

This goal is achieved by the fact that the installation is equipped with a fixed on the axis of the template of the carbon dioxide, which, when centering the interaction, acts with two levers acting on the proximity sensors, while the ends of the levers in contact with the stop are located one above the other.

Nafig 1 shows a general view of the installation; in fig. 2 - section along the AA.

The installation contains a meta-design 1, on which the frame 2 moves by means of the drive 3. A drive platform 4 with mechanisms 5 for supplying lining materials is suspended from the frame. Under the rotating platform, the template 6 is located in the bucket 7 with it.

Metal structures can be made in mobile and stationary versions. In the mobile version of the metal structure, it has a mechanism of 8 longitudinal quarter-shifting In the case of a stationary version of the Research Institute of Metal Structures, the ladle is supplied to the unit on a track with a Longitudinal movement mechanism (in Fig. I, a truck with a longitudinal movement mechanism, not shown) ... h.

The frame 2 is moved but the metalwork in the direction perpendicular to the movement of the metalwork or trolley with a ladle. B. The frame is built in DISK-BREW feeder 9 with drive) 10, turntable .11 with drive 12. The turn of the frame .13 is attached to the turntable, to which a rotating drive platform 4 is suspended on racks 14. The current collector is integrated between the round frame and the disk feeder. 16. The lining material delivery mechanism consists of a sanding head 17 mounted on a swinging arm with a drive and a conveyor 18 fixed to the frame 19. The angle of inclination of the sanding head and extending the sand face to the direction The frames vary depending on the diameter of the forging and the angle of its wall.

Two levers 20 and 21 (Fig. 2) of the axis of the hinges 2-2 of which Oi and 02 (Fig. 1) are located on the same straight, passing through the axis of the platform, are attached to the lower plane of the driving platform 4. Both levers are interconnected by springs 23 and 23, set. Levers in the initial position along one straight line passing through the axes of the hinges. The end of the outer part of the levers is embedded in the form of a fork, on which the roll of the plate 25 (Fig. 2).

The position of the plates on the fork is adjustable. Internal kotstsy levers bent downwards and located one above the other. To the bottom, the plane of the metalwork site along the axis of the installation, perpendicular

in the direction relative to the movement of the steel structure and the ladle, two position sensors 26 are applied, which are affected by the plates 25 of the levers.

On the top plane of the template 6 by its

5, a cylindrical stop 27 is fixed in which the inner parts of the levers 20 and 21 abut against the installation and the bucket.

On the lower plane of the upper platform of the metalwork along the axis of the installation, perpendicular to the direction of the relative movement of the metalwork and the bucket, the sensor is a position sensor 28 (Fig. 1), which is affected by the plate 29 mounted on the round frame 13 along the same axis

5 setups.

Installation by installation is done from the remote control 30.

The installation works as follows. The ladle prepared for stuffing the lining is placed on the air or we or carts.

The actuator 12 of the turntable 11 is turned on, and the frame 13 vranlaets until the plate 29 acts on the position sensor 28. In this position, the levers 20 and 21 of the centering device will be

5 are arranged perpendicular to the direction of the relative movement of the metal structure and the ladle. The position sensor 28 turns on the indicator lamp on the pump 30 and gives a discharge signal to the control circuit of the relative longitudinal transfer mechanism.

0 Megzen metalwork or trolleys with a ladle, after which this mechanism is switched on from the console.

When approaching the bucket, the movement mechanism switches to the med5 speed and the stop 27 fixed on the template 6 presses the levers 20 and 21. If the axis of relative movement of the frame 2 does not coincide with the axis of the cylindrical stop 27, then one of the levers 20 or 21 deviates by a larger angle and acts on one of the sensors.26, which turns on its indicator lamp on the console, turns on the mechanism of relative change; metal structures or carts and turns on the drive 3 nepeMenieHHH frames 2 in the direction of decreasing Hieinui of the angle of inclination of this lever.

When the angle of deflection of the lever decreases, it ceases to act on the sensor, the sensor signal disappears, the metal structure or the carriage turns on the movement in

In the same direction and the indicator lamp goes out on the remote. Cylindrical, the stop 27 pushes the levers again and, if the installation axis does not coincide with the template axis, the process is repeated.

5 At the simultaneous generation of signals from both sensors 26, both indicator lamps on the console light up and both movements are switched off in two mutually perpendicular p

directions. Centering is complete.

Possible centering and in manual mode. In the manual mode, the movement mechanisms are activated manually according to the indications of indicator lamps on the console.

Impact of the levers 20 and 21 on the cylindrical stop 27 can be on both sides.

Further include actuators of sand burrs 17, conveyors 18, disk feeder 9, rotation of platform 4 and workshop supply system, refractory mass to the installation. Lining of the walls of the ladle is being completed. After the packing is finished, the mechanisms are turned off in reverse order, the carpet is removed from under the installation, and the template 6 is removed.
