Description

/////////// Figure 1

The invention relates to a handling equipment, and in particular to mechanisms for fixing elements of the load handling device.

The purpose of the invention is to increase the reliability of operation.

FIG. 1 shows the locking mechanism used to hold the transoms of windows of industrial buildings, a general view; in fig. 2 — fixation mechanism at the moment of hovering the suspension with a figured notch on the finger; in fig. 3 - the same, at the moment when the finger enters the shaped neckline; in fig. 4 - the same, at the moment of fixation of the elements of the load gripping device;:;:, a.

.: cops 1 and 2 of the locking mechanism of the load gripping device are hinged on axles x 3 and 4. On axis 4, hingedly mounted suspension 5 with figured notch 6. On suspension 5 by means of axis 7 fixed 8, which overlaps cutout of suspension 6, limiters 9 and 10, made with the protrusion 11 and spring-loaded spring 12.

On the suspension 5, the lever 14 is also pivotally fixed by means of an axis 13, the rotation of which is limited by an emphasis 15 and a spring 16, having a notch 17 which is covered by a flap 18 pivotally mounted on an axis 19.

The valve 18 is installed with the possibility of limited rotation using the limiter 20 and is spring-loaded spring 21.

On the element 2 of the load gripping device, the finger 22 is rigidly attached.

The fixation mechanism works as follows.

In the initial position (Fig. 2), the plate 8 overlaps the shaped notch 6 of the suspension 5. When the elements 1 and 2 move each other towards each other, the finger 22, acting on the projecting part of the plate 8, rotates the latter, while the protrusion 11 enters the notch 17 of the lever 14, and the plate 8 itself is placed in the figured notch of the suspension 5 with the possibility of interaction with the finger 22. In such a position of the plate 8, part of the figured notch of the suspension remains open.

When the direction of movement of elements 1 and 2 is changed, the finger 22 enters the open part of the notch 6 of the suspension 5, interacts with the plate 8, turns it, while the protrusion 11 of the plate 8 moves back the shutter 18 which, by the action of the spring 16, overlaps the notch 17 of the lever 14, and engages lever 14.

In this position, the elements 1 and 2 of the load-carrying device are fixed with each other.

During the subsequent movement of the elements 1 and 2 towards each other, the finger 22 extends beyond the figured notch of the suspension 5, and the plate 8 rotates under the action of the spring 12. The plate protrusion interacts with the flap that is held from the rotation by the stop 20, the lever 17 passes through, and the plate 8 overlaps the suspension neckline. Items 1 and 2 are disconnected.
