Abstract

Usage: in the process of turning over large structures, in particular metallurgical tanks. SUMMARY OF THE INVENTION: the device comprises a platform 1 with grippers mounted on the supports 2 of the base, and hydraulic cylinders 4 and 5 for turning the platform 1. A new device is the equipment of the platform 1 at the ends of two pairs of coaxial trunnions 3 mounted one above the other in the supports 2 and pivotally connected to the rods of the actuator hydraulic cylinders 4 and 5 with the possibility of alternately sequentially moving one pair of pins relative to another, which are mounted in grooves made in supports 2. 4 ill.

Description

Figure 1.

The invention relates to the mechanization of the process of turning over large structures, for example, metallurgical tanks, in the repair of products in metallurgy, mechanical engineering, and other industries.

The aim of the invention is to expand the operational capabilities and increase the reliability of the device.

. FIG. 1 shows a device for can. side view; figure 2 is the same, after the rotation of the platform by 90 °; Fig. 3 shows the same after turning the platform 180 ° from the initial position; . Fig. 4 is a view along arrow A in Fig. 1.

The device for tilting large-sized structures, mainly metallurgical containers, comprises a platform 1, supported by supports 2 of the base by means of supports 2 of pins 3 mounted in grooves, the ends of which are pivotally connected to the rods of two pairs of hydraulic cylinders 4 and 5. The pins 3 are mounted in. the grooves of the supports 2 by means of bushings 6 with flanges. On the platform 1, a container is installed, for example, an intermediate bucket 7, fixed with grippers 8.

The tipping device operates as follows.

On the platform 1, the crane installs an intermediate bucket 7 and is fixed by means of grippers 8. In the initial position, the hydraulic cylinder rods 4 are drawn in and the hydraulic cylinders 5 are extended. The hydraulic cylinders 5 are turned on for retraction of the rods, at

this platform 1 with an intermediate bucket 7 rotates 90 ° relative to a pair of pins connected to the rods of the hydraulic cylinders 43 (see figure 2). After that, the hydraulic cylinders 4 are turned on to extend the rods and the platform 1 rotates 90 ° relative to the pair of pins connected to the rods of the hydraulic cylinders 5. or 180 ° from the initial position (see Fig. 3). In this case, the vertical axis of the platform 1 and the bucket 7 as a result of two strokes of the hydraulic cylinders 4 and 5 is shifted in the horizontal plane by a step equal to the distance between the trunnions 3. Returning to the initial position is carried out in the reverse order, first the hydraulic cylinders 4. and then the hydraulic cylinders 5 .
