Description

The invention relates to metallurgical equipment and naflavleno for further development of the lifting machine of the vacuum cleaner, which is intended for transferring, weighing and vertical movement of the ladle with liquid steel in the process of evacuation. The lifting and transporting machine works as part of a vacuum complex with a fixed vacuum chamber. The known design of the steel truck, which is designed to transport the bucket and repair, install the suction inlet nozzle of the vacuum chamber. The steel train consists of a frame supported by the driving wheels, the bucket is mounted . The frame is also fitted with a hydraulic jack with a pumping station, which lifts and lowers the repair table with the ij mounted on it. The known design of the vacuum lifting machine is taken as a prototype, which consists of a frame. the support wheels, which are supported by bearings, are equipped with equal shoulder rotations in Koropijix: gi, which interact only with platform and amp; and the bucket support ring, and the other with a rack pusher placed in the guide frames. The rail plunger, which simultaneously serves as a counterload, interacts with the gears of the drive 2. Technological possibilities of the design are limited to transportation by lifting and swinging the bucket with metal. The purpose of the invention is to expand the technological capabilities of the lifting and transporting machine of the vacuum tank by ensuring that another operation is performed, for example: repair, installation and maintenance of the suction port of the vacuum chamber. This goal is achieved by the fact that the rack pusher is equipped with a turntable, on which the caisson is movably mounted. FIG. 1 shows a general view of the device; .on FIG. 2 - the same, top view. The hoisting and lifting machine consists of a frame 1 supported by driving and non-driving wheels 2 combined in a balance bar. The drive of the traveling wheels 2 of a known design is made in the form of vertical gearboxes mounted on the console part of the shafts of the traveling wheels, electric motors and brakes. On frame 1, from one storzha from the transverse axis, a support block 3 is installed with supports for a bucket 4 and a platform 5, placed in frame guides 6, and on the other a rack plunger 7 placed in guide 8 frames 1 and a rack pusher drive 9. In the middle part of the frame 1, on both sides, are mounted. Supports 10 with rolling bearings, in which the pivot pins have two equal-arm levers 11. The levers 11 are connected by one ends to the platform 5 by means of t g 12, and the others by a rack pusher 7 through balancing beams 13 and grams 14. The support ring 3 with the bucket supports 4 is freely supported by three legs on the frame 1 and is mounted above the platform. The horseshoe-shaped platform 5 is provided with guide rollers 15, with which the station is placed in the guides 6 of the frame 1 ,. (not shown on the drawing), which serve to determine the weight of the ladle with metal. Platform 5 provides for vertical movement of the bucket 4 mounted on the support ring 3. Ti 12, 14 are spherical supports and allow the translational movement of the platform 5 and the rack pusher 7 to transform the KOHUt levers 11 into a curved motion of the levers 11. The levers 11 with trunnions in the middle the parts serve to transfer forces from the rack rail actuator 9 to the platform 5 and move it in the guides, 6. The rack plunger 7 with two oppositely located Toothed rails 16 is placed in the guides 8 of the frame 1. In the lower part the rack pusher 7 is provided with supports, an I balance beam 13 is installed on the axle. On the axles of the balance beam 13 on axles with spherical sliding bearings, 14 h are mounted, which interact with the ends of the levers 11. Each gear rack 16 engages a gear with two gears 17 mounted in bearings of rotary forks 18 for self-alignment gear tooth on rack tooth Rotary forks 18 are installed in pairs in cases of rack gears 19, mounted on frame 1. Gears 17 are connected to drive 9. In upper part of rack and pinion gears The cartridge 7 is installed, on the rotary platform 20, the caisson 21 with elastic elements 22 (e.g., springs). A repair platform 23 is installed in the upper part of the frame 1, which, together with the caisson 21, serves to repair, install and service the suction nozzle 24 of the vacuum chamber 25. The elastic elements 22 serve to limit the pressing force of the caisson 21 with the suction inlet 24 to the vacuum chamber 25. In the caisson 21 there are openings for inspecting and repairing the suction inlet. The machine can operate in two modes: overhead transport and repair. In the lifting-transport mode, the machine operates as follows. The metal bucket 4 filled with liquid metals is installed by the workshop crane on the supports of the operative ring 3. The plate 5 is at the same time in its lowest position. The rail plunger 7 is in the extreme upper position and the guides 8 of the frame 1 and is prevented by the actuated actuator 9 from moving. After installing the bucket 4 with metal on the displacement drive machine, the machine is transferred under a vacuum chamber. When the drive 9 of the rack pusher 7 is turned on, the engines transmit gears through gears to the gears 17 which engage with the toothed racks 16 of the rack pushers 7. The torque of the gears 17 to the tooth; The rails 16 are transformed into a pushing or bore force on the pusher 7, evenly distributed between the levers 11 and the balance beam 13. The translational movement of the rack pusher 7 through the tg 12, 14 with spherical hinges at the ends converts the rotary movement of the ends of the levers 11 and a translational platform 5 moving in vertical guides 6. Having reached the extreme upper position, the support ring 3 with the bucket 4 mounted on it is brought into the lowering mode. Having performed ZO-4O swings at a given speed with a stroke at which the nozzle 24 of the vacuum chamber 25 remains in the metal, the bucket 4 on the support ring 3 is lowered into the lowest position and is brought into the zone of the shed of the crane for transfer to the next technological operation.

In the repair mode, the vacuum handling machine operates as follows.

After finishing the evacuation cycle and transporting the ladle with the evacuated steel to the casting: the lifting machine is transported under the vacuum chamber 25 and stops when the axis of the caisson 21 is aligned with the axis of the suction inlet 24 of the vacuum chamber 25. By means of the actuator 9, the slider pusher 7 moves up, and the caisson .21 enters the suction nozzle 24. Then, an inspection is carried out and the current minor repairs to the suction nozzle 24 through the window lining of the caisson 21. At the suction nozzle 24, the caisson 21 nimaets rack tappet 7 of the nozzle and the nozzle is detached from the vacuum chamber, which are interconnected by bolts otkidn1mi. The machine disconnects the nozzle 24 to the crane's zone of action, which instead of the old one into the caisson sets the HOBI suction seal. The machine then moves back and stops under the vacuum chamber when the ifeccoHa axis is aligned with the wasp hole and the vacuum chamber. The rack pusher 7 moves upward and presses the caisson 21 with the suction nozzle 24 installed in it to the vacuum chamber 25 with the force necessary to ensure the vacuum density of the joint. Then the bolts are tightened. After the installation of the suction pipe 24 has been completed, the rack pusher 7 is lowered and the machine performs the following process step.

As a result of the execution of the rack pusher in the upper part in the form of a rotatable platform, on which the caisson is movably mounted, we lift

The metal1 of the same machine remains the same, since the additional weight of the keo owl KOMneRctq yet4 :: fl allows us to weigh the weight of the cart load of the hopcatep.

The area of the workshop is reduced, which is loaded with the technical equipment of the vacuum equipment using the repair trolley.

Simplified by the control of technical equipment, the equipment of the vacuum cleaner, since there are only two machines due to the interlocks, which complicates the management of the vacuum cleaner.

The economic effect with the introduction of the proposal will be about 50.
