Gripping device for massive slices

The invention relates to a device according to the preamble of claim 1.

The invention is intended in particular for handling metal disks, for attaching them to machine tools or to store them before or after processing.

In machining workpieces, an overhead crane often massive metal disks with great thickness and large Diameter to be handled, e.g. B. disks with a diameter of up to 1 m and a thickness of 200 to 300 mm.

With discs drilled through in their center, it would be easy to pass rope loops through the central opening, to safely lift the pane. With massive panes one is practically forced to either the Slice through a rope loop with a kind of running knot to enclose without actual security on the circumference of the disc, or to clamp the disc with

the risk of damaging its side surfaces or of grabbing the disc by an electromagnet that magnetizes it. The problem is particularly delicate at the moment when the disk is gripped or put down, since the danger often arises or has to arise when the disk lies flat on supports so that it can finally be gripped by means of a fork carriage. At the moment of lifting, the rope loop surrounding the pulley with a horizontal loop is pulled vertically upwards by the hook of the overhead crane and therefore has a tendency to slide on the pulley, as the running knot can hardly have a self-locking effect in this position. In the same way, the disk assumes an intermediate position between the vertical transport position and the flat rest position, in which the rope loop runs the risk of sliding off and the disk runs the risk of falling violently onto its support. Such handling constitutes'^;

therefore at the same time a risk of accident for the staff and ρ a risk of damage to the rope slings or the Share yourself.

The object of the invention is to create a device of the type specified at the outset which avoids these disadvantages.

This problem is solved by the characterizing features of claim 1.

Advantageous further developments of the invention are the subject matter of claim 2.

The invention is described with reference to the drawing. It shows:

Fig. 1 is a side view of a device according to the invention, attached to a disc to be handled and ready to be lifted by a lifting device;

- 5 - Fig. 2 is a plan view of Fig. 1,

According to the drawing there is one to be used Disc 1 in waiting position on two pieces of wood 2, on which they were previously, for example by means of a fork carriage were filed. The gripping device mainly consists of a fork-shaped or Y-shaped part with a common one Legs from two parallel »by spacers 5 and 6 separate bars 4-. The rods 4 then diverge to form the legs 7 of the fork, which in turn are bent at their ends 8 by 90 ° with respect to the fork plane. An approach or a reinforcing rib 9 made of cut-to-size Sheet metal is welded to the outside of the curvature of the legs 7, 8. The width of the reinforcement rib 9 is greater at the curvature and decreases towards the end of the leg 7 and 8, respectively.

A slider 11 is between the rods 4 with little Play included that allows it to slide along the bars. The path of the slider is through the Spacers 5 and 6 limited. The slider has a central hole in which one in a hook 13 on one End curved rod 12 is used. The rod 12 is provided with a handle 15 at its other end Stop piece 16 used. The rod 12 slides freely in the sliding guide 11 and can in a certain Number of given positions can be locked by a pin 17, which simultaneously the sliding guide 11 and one or the other of a series of holes in the rod 12 traverses. The pin 17 is by means of a small Chain 18 held on slider 11.

The rods 4- are opposite at their forked legs 7 The ends are bent over at 20 and form a dispensing head for a lifting ring 21.

^· To raise the resting on its supports or pieces of wood 2 disc 1, the device is placed on the disc by the ends are brought 8 of the legs 7 in contact with the cylindrical surface of the disc. The hook 13 is then at a distance and is turned over. When the device is correctly centered on the disc by the free abutment of the ends 8, the slide 11 is displaced until the rod 12 contacts the disc. The pole

'■} is then set by the handle 15, namely loading

; plus alignment in order to fold the hook 13 towards the pane, and with respect to the longitudinal position in the slide, around the hook 13 in contact with the flat surface of the disc bring to. If necessary, the hook is then slightly

* neatly removed to make a hole in the rod with the pin 17

to be brought into congruence so that the rod can be locked in the slide ■. The device is then ready

to lift the pane.

If, for example, an overhead crane is used on the in the A rope loop 22 inserted into 21 is pulled the disc is first lifted by the hook 13, and the arrangement begins to straighten up. When the disc is completely suspended in the vertical on the rope loop, it rests on the bent ends 8 of the Leg, while the hook 13 makes any tilting impossible.

; During the manipulations, the handle 15 is also used for

Guiding the movements.

In the case of a reverse handling for placing the disc on a carrier, the arrangement contacts the carrier when it is lowered First floor with the most protruding part of the reinforcement ribs 9- When the rope loop is further lowered the whole tilts around the reinforcing ribs, whereby the arrangement gradually changes to that shown in FIG horizontal position can be transferred. During the

Tilting, the disc remains locked by the hook 13 and cannot yet emerge from the ends 8 of the legs.

The device can be attached to discs with different Adjust diameter and different thickness. In the figures is the position of the slider and the rod 12 with the hook 13 for a disc 24- with a smaller one Diameter and smaller thickness than that of the disc 1 shown in phantom.

Of course, the invention is not necessarily limited to the embodiment described as an example, but also includes the embodiments that only through details, design variants or through application equivalent means differ. The invention thus relates to the handling and mounting of wheels with very large dimensions in public works, on commercial vehicles or in aviation.

It could thus be observed that the sole frictional or clamping forces are generally sufficient to keep the slider in place during movements. But it could also be used to increase security a more inevitable fixation of the slider on the rods, e.g. B. by a simple device with "locking screw are provided.
