Abstract

The invention relates to foundry. The purpose of the invention is to improve serviceability, simplify the control of the tilting process and improve reliability, as well as compensate for inaccuracies in the position of the hooks relative to the grip pins when gripping. The tilter contains a longitudinal traverse with a drive, a suspension for connection with a hook of the load-lifting mechanism and two vertical beams, and a transverse traverse at the lower end of each hinge. At each end of the transverse crosshead, hooks are installed to grip the trunnion trunnions. To be able to rotate them in a plane perpendicular to the centering axis, the hooks are attached to the traverse pivotally by means of the axles, and to be able to swing along the axis of turning they are fixed to the axis by means of fingers. On the underside, the hooks have a bevel for interacting with the trunnion trunnions. The tilter is hung on the hook of an overhead crane by means of a suspension. 2 hp ff, 6 ill.

Description

The invention relates to foundry, in particular, to auxiliary lifting mechanisms, intended for transporting and turning the flasks or casting molds.

The purpose of the invention is to improve serviceability, simplify control of the canting process and increase reliability, as well as compensate for the inaccuracy of the position of the hooks with respect to the axles of the supports when gripping.

FIG. 1 depicts a suspended tilting hanger with a flask suspended from hooks; in fig. 2 - the same view

from the side; in fig. 3 is a section A-A in FIG. 2; in fig. 4 is a view B in FIG. 3; in fig. 5 - the position of the transverse cross member with hooks when turning; Fig 6 - carriage, longitudinal section;

The tilting device includes a longitudinal yoke 1 with two vertical beams 2, which can be fixedly attached to the yoke 1 when canting the flasks of the same size. When tipping the flasks of various sizes, the upper ends of the beams 2 can be connected to the yoke 1 by means of carriages 3 that are mounted with the possibility of moving along traverse 1 along tracks 4 to grow

5. The rotary actuator includes an electric motor 6 with a gearbox 7, a lead screw 8 with right and left threads, which is connected with nuts 9 fixedly in the carriages 9. Driving elements are mounted in coaxially arranged shafts 10 in the form of sprockets 1 attached to the carriages mounted on shafts with the possibility of longitudinal movement along the keys 1 or the slotted sections of the shafts.

At the lower end of each beam 2 is articulated by the middle part of the transverse traverse 13. Here are the driven elements in the form of stars 14, which are rigidly connected to the transverse traverse 13 by means of shafts 15, whose necks are fixed with the possibility of rotation in the vertical beams 2. The driven stars 14 associated with drive sprockets 11 by means of drive chains 16, for example sleeve-roller. At each end of the transverse beam 13, hooks 17 are installed to grip the trunnions 18 of the flasks 19. To enable them to rotate in a plane perpendicular to the tilt axis, the hooks are attached to the yoke 13 pivotally via the axles 20, and for swinging along the tilting axis they are fixed on the axis 20 by means of fingers 21. On the underside, the hooks 17 have a one-sided bevel 22 for engagement with the flasks 18 pins.

The tilter is hinged on the hook of an overhead crane by means of a suspension 23. The tilter can be controlled using the pendant or from the cockpit of an overhead crane

Suspended tilter works as follows.

The tilter suspended on the hook of the crane is installed above the flask 19 and when lowering, bends 22 hooks 17 of the journals of the trunnions 18. When lowering further, the hooks deviate from the vertical position and seize the trunnion necks. The inaccuracy of the position of the hooks relative to the trunnions of the flasks along the axis of turning is compensated for by the hinged attachment of the hooks to the axles by means of fingers.

The actuator turns the actuator through the drive sprocket 11 and the drive chains 16 and transmits the rotation to the driven sprockets 14, which transmit the rotation to the transverse crossbars 13 through the shaft 15. In the course of the rotation, the hooks keep their vertical position on the axes 20 The flask 19 is here rotated together with the yoke 13, while being parallel to the traverse. In the process of turning, the flask can be stopped at any desired angle in the horizontal plane. This ensures reliable fixation of the flask by a self-locking drive, which is especially necessary when finishing the half-form.
