Description

The invention relates to mechanical engineering, in particular, to equipment for the assembly and welding of large-sized units in electric furnaces, and can be used in other parts of the industry.

The purpose of the invention is to increase productivity, reduce the occupied area and expand technological capabilities.

Figure 1 schematically depicts ... the proposed tilter; Fig. 2 shows a kinematic diagram of a drive for moving the frame of the turn-off device; in Fig.3-8 - the scheme of operation of the turn-off device.

The tilter contains guides 2 with rail 3 and additional guides 4 mounted on the base 1, on which are mounted with the possibility of reciprocating movement of the column 5 with guides 6, executed in the form of a loop of cycloid and stops 7 with cycloid bearing surfaces.

The tilter is also equipped with a load-carrying swivel frame 8c with a drive 9 for its movement. The actuator 9 is equipped with an output gear 10 installed with the ability to interact with the rail 3. The frame 8 is equipped with wheels 1 1 installed with the ability to interact with guide rails -2, rollers 12 installed with the possibility of interaction with guides 6 hundred-g ek 5, and rollers 13, installed with the possibility of interacting with the cycloidal support surface of the stops 7; On the frame 8, there are pivotally mounted earrings 14 and 15 of equal length;

The length of the rod 16 is equal to the distance between the axles of the hinge fixing of the earrings 14 and 15 on the frame B. Output, the turn 10 is installed on the axis of the hinge fixing of the earring 14 on the frame 8, and the wheels 11 are mounted on this earring symmetrically relative to the gear 10. The rollers 12 are mounted on the axis of the swivel joint gi 16 with the shackle 15, and the rollers 13 mounted on the rod from the axis of the swivel joint of the gigant 16 with the stud 14 equal to 2L /, where L is the distance between the axes

t gi.

The actuator 9 contains an electric motor 17, connected via a worm 18 and a cylindrical 19 transmission with

gear 10. Frame 8 can be equipped with a faceplate (figure 1 is conventionally shown) with a drive roller 20 for transmitting rotation. In this case, the roller shaft through a bevel gear 2 and a clutch 22 with an electromagnetic drive 23, as well as a cylindrical 19 and a worm gear 18 is connected to the electric motor 17.

On the basis, tension sprockets 24 are mounted, covered by chains 25, the ends of which are fixed on the axles of wheels 11. Racks 5 are connected to chains 25 and are equipped with electromagnetic shoe brakes 26. The tilter is equipped with a tensioning mechanism of chains 24 screws 27. Base, 1 is made with a mirror, and frame 8 is with windows.

Tilter works as follows.

The tied product is placed on the carrying frame 8 and secured. When the drive 9 is turned on, the frame 8 moves, interacting the gears 10 with the rails 3, resting the wheels 11 on the guides 2 and the rollers 12 on the guides 6 of the racks 5, while the frame 8 chains 25 moves to the opposite side of the rack 5 along additional directions 4, turning around the hinges of the earrings 14 and 15 tons 16 with the rollers 13. The latter, interacting with the stops 7, do not allow the product to spontaneously tilt the frame 8c into an unstable equilibrium position. The product can be turned, if necessary, by 180 into the base 1 strut and assembly and welding works are performed through the windows of the frame 8. The relative positioning of the guide lines 6 and the tension of the chains 25 are adjusted by moving the screws 27 along the base slots 1. Life Stars 24.

If it is necessary to rotate the product at different angles of inclination to the horizontal plane, a faceplate is installed on the load-carrying frame 8, the gears are connected to the roller shaft 20. When the drive 9 is turned on, the electric motor 17 (Fig. 3) transmits torque through the gears 18 and 19 on the gear 10, which set the frame 8, faceplate and product in the desired position. Includes an electromagnetic actuator 23, which

Secondly, the clutch 12 of the gear 10 stops the movement of the frame and the twisting moment through the gears 18, 19 and 21 is transmitted to the shaft of the roller 20, which rotates the faceplate with the product. The required rotational speed of the product is provided by adjusting the rotational speed of the motor .17. Simultaneously with the inclusion of the electromagnetic JQ drive 23, the electromagnetic shoe brakes 26 of the uprights 5 are activated, creating a clutch of the latter with the direction. And to prevent spontaneous movement of the load carrying (5 frame 8. Installing racks 5 with guides 6 with the ability to move when moving pai-iM and the size of rollers 12 and rollers 13 per ton 16 allows you to increase productivity 20 and reduce the production area occupied tilter when turning the product on 180, to improve the working conditions of the mechanisms, which will increase the service life of the guides. 25

In addition, equipping the turner with a faceplate, and the actuator 9 with a coupling for sequential switching on either the shepherd 10 or the roller 20 for rotating the faceplate is expanded by its JQ technology. opportunities.
