Description

I

The invention relates to load handling devices, especially designated for transshipment of specialized containers and containers, equipped with load handling grips in the form of openings.

A load gripping device is known, comprising a traverse, a carrier frame associated with it, on which the gripping bodies are mounted, and a mechanism for fixing them in the open position flj.

However, this device is complex in design and not reliable enough in operation.

The closest proposed load gripping device comprises an upper frame with a device for connecting it to a lifting mechanism, a lower frame connected to it, on which the gripping hooks are hinged, and a mechanism for fixing the relative position of the upper and lower frames 2j.

A disadvantage of this device is the complexity of its design due to the presence of transmission arms and hinge links connecting the hooks to the locking mechanism.

The purpose of the invention is to simplify the design to ensure the operation of the device in cramped conditions.

This goal is achieved by the fact that vertical stands are rigidly fixed on the upper frame, each of which has a protrusion for interacting with the outer surface of the hook.

In this case, the outer surface of each hook can be made with

5 bevelled.

FIG. I schematically depicts the proposed device, a general view {in FIG. 2 - gripping hook and stand.

The device consists of an upper section 1 with a device for attaching it to the load-lifting mechanism of the bottom frame 2. A mechanism 4 of coupling 3 of their relative position is installed between the upper and lower frames. On the frame 1 there are rigidly fixed vertical supports 4, each of which has a protrusion 5. On the frame 2 on the axles 6 there are fixed hooks 7 having bevels 8. The hooks interact and with holes 9 in the container or pallet 10.

The device works as follows;

When the container (pallet) is grabbed, the 10th upper frame I and the lower frame 2 are at the minimum distance from each fugue, and the hooks 7 occupy a vertical (inoperative) position. In this position, the device is lowered by the fta container. When the device is lifted, the locking mechanism triggers. 3. Racks 4, Mbyiniy, slide upward with their protrusions 5 along the bevels 8 hooks 7, leading them to the outside. The hooks 7 enter with the ego into the holes 9 of the container 10, seizing it.

After the container is lowered together with the gripping device to the desired location of frame I and 2, fic-jj approach each other.

The CHyibTCH is in this position by the locking mechanism 3, the uprights 4 are lowered downwards and removed from the interaction with the hooks 7, which occupy the non-operating position. The device is thus freed from the container.

Claims (2)

1. Load-carrying device, comprising an upper frame with a device for connecting it to a lifting mechanism, a lower frame connected to it, on which the gripping hooks are hinged, and a mechanism for fixing the relative position of the upper and the lower frame, distinguished by the fact that, in order to ensure the operation of the device in cramped conditions, vertical posts are rigidly fixed on the upper frame, each of which has a protrusion for interacting with the outer surface of the hook. 2. The device according to claim 1 of tl and is eu with the fact that the outer surface of each hook is made with a bevel. Sources of information- taken into account poi expertise 1.
