Description

• j i.

The invention relates to a tilting lifting mechanism with a pulley block for tilting a pouring ladle with a load hook engaging in a side flap of the pouring ladle.

There are known tilting lifts for ladles that are either attached to an auxiliary trolley that is independent of the main trolley is movable, or which are arranged on the frame of the main trolley. When tilting the ladle, the load hook must be brought into engagement in a side tab of the ladle, whereupon by actuation of the tilting lifting mechanism the tilting is carried out. When the load hook is attached to its own independently movable auxiliary trolley is, a horizontal movement or adjustment is possible, but the design effort is for a separate auxiliary trolley relatively large. If, on the other hand, the hook is attached to the frame of the main trolley, the can be adjusted horizontally Hook is not known, but the hook must be operated by an operator man can be brought into the engagement position.

The invention aims to avoid the disadvantages outlined and difficulties and has the task of creating a tilting hoist that is attached to the main trolley However, in contrast to previous solutions, the load hook is horizontally adjustable and automatically moves into the engagement position.

This object is achieved in that the Load hook arranged on a lever rotatably mounted on the bottom block and under the action of a counterweight in the Engagement position of the hook can be swung out.

The lever is advantageously designed as an angle lever, the load hook being articulated to an arm and the counterweight attached to the other arm.

According to a preferred embodiment of the invention, the counterweight is suspended from a winch separate from the pulley system, wherein the weight of the counterweight is compensated by a standstill motor.

It is advantageous if a slot-shaped recess for a single-rope suspension is provided in the counterweight is.

The axes of the rollers of the bottles are expediently rotated by 90 relative to the axis of the drum of the cable winch.

The load hook 3 is articulated to a rocker arm 5; the rocker arm 5 is pivotably mounted on the bottom block 6 with the bolt 7. The second arm 8 of the rocker arm 5 has a counterweight 9 charged; the counterweight 9 being suspended from the control cable 11 around a bolt 10. There is another one in counterweight 9 Slit-shaped recess 12 is provided in which the control cable 11 is movable. The lower block 6 hangs with the rope 13 on the upper block 14, the axes of the rollers both, the lower as also the upper bottle 15 and 16 by 90 ° relative to the axis of the drum 17 of the winch are twisted, which has the advantage of a particularly flat design.

The function of the device according to the invention is as follows:

When the load hook 3 is to be brought into the engagement position shown in phantom in the drawing, the moment of the standstill motor 21 is weakened so that the counterweight 9 moves downwards and the angle lever swings out by 90, the load hook 3 as a result of it articulated fastening | supply swings hanging vertically and reaches into the engagement position overall].
