The invention relates to load gripping devices.

The aim of the invention is to improve the reliability of the device.

FIG. 1 shows a schematic view of a gripping device with a container, side view; in fig. 2 - stand with locking mechanism in the initial position; in fig. 3 shows section A-A in FIG. 2; in fig. 4 shows a section BB in FIG. 2; in fig. 5 - stand with a locking mechanism at the exit of the hollow element of the container.

The pickup device contains a supporting frame 1 (Fig. 1) with vertical posts 2, in which windows 3 and 4 are made (Fig. 2). and windows 5 are perpendicular thereto, and windows 3 and 4 are located on opposite sides of vertical posts 2. In each window 3 on axis 6 there is a sprung / th /. Private element 8 with fixation i, containing the lower arm 9, located in window 4, sub-loaded with the help of 10 and connected by a rod 11 in the form of a rigid rod with a spring-loaded spring 2 by a stopper 13i which communicates with the upper arm 14. The latter is placed in window 5 and is connected by an additional rod 15 to the gripping element 8. Moreover, the lower end gi 11 pivotally connected with the lower lever 9, and the upper end is equipped with a T-shaped hook 16 and placed in the river slot 17 of the stopper 13. The stopper 13 is complete with a longitudinal slot 18 along which it moves in the transverse groove 17 of the hook 16 Additional ha 15 (FIG. 4) with one end rigidly connected with the upper arm 14, and the other, made with the opening 19 in the form of a flat closed frame, covers the connecting axis 20 fixed to the gripping element 8. Moreover, the additional cable 15 has an H-shaped section, and

the end with the opening 19 is placed in the longitudinal slot 21.

 To limit the angle of rotation of the stopper 13, a side stop 22 is provided, and for the gripping element an 8 stop is provided 23. The device cooperates with a container 24 having hollow elements 25 with side openings 26 and 27. The gripping device for containers with hollow elements works as follows.

The device is hung on the load-lifting mechanism, is led over the container 24, has a stand 2 above the hollow elements 25, and lower it. In this case, the locking mechanisms located in the racks of the device, under the action of the springs, are in the initial stress-balanced state. The gripping element 8 is pressed by the spring 7 against the stop 23. The spring 12 presses the stopper 13 against the side stop 22 and fixes the spring 10 by means of the rod 11, fixing it in the horizontal direction. horizontal position of the lower arm 9. The upper arm 14 rests on the bottom of the window 5, and is limited on the top by a stopper 13. I An additional 15 hectares connected to the upper arm 14, the connecting axis 20 of the gripping element 8 is freely below.

Upon further movement of the device down the legs 2 enter the hollow elements 25 and the lower lever 9, abutting

the wall of the container is rotated around an axis, stretching the spring 10. T ha 11, the lower end of which is pivotally connected to the lower lever 9, rises and its upper T-shaped hook 16 moves upwards along the transverse groove 17 of the stopper 13. As it advances down the device, the bottom tag 9 enters the side opening 26

container and under the action of the spring 10 occupies its original position. The gripping element 8, retaining the container wall, rotates around axis 6 and stretches the spring 7. In this case, the 31 connecting axis 20 of the gripping element 8 freely moves in the covered contour of the closed frame 19 of additional 15 g. the gripping element 8 falls from the side opening 27 of the container, the spring 7 returns the element to its original position until it stops 23. When the device is lifted, the gripping element 8 abuts against the upper edge of the opening of the wall of the container 24 and lifts it upwards. After moving the container 24 with the load to the place of its storage, the device is lowered down, the container is placed on the supporting surface, and the pillars 2 under the action of their own weight of the device continue to fall down. As the rack moves down, the gripping element 8 rests on the lower edge of the hole 27 and, turning around axis 6, expands the spring 7. Then the upper lever 14 abuts the top of the flat element 25 of the container and, moving up in the windows 5, depresses the stopper 13 , drag spring 12. At the same time, the upper lever 14 continues to turn the gripping element 8 by means of additional pulling. 9 When the upper lever 14 reaches the extreme upper position, the stopper 13 under the action of the spring 12 returns to its original position until the side stop 22. The upper The lever 14, resting on the stopper 13, fixes the gripping element 8 in the rotated inoperative position by means of additional pulling rod 15. The device is lifted up to unlatch. The pillars 2 move in the hollow elements 25 of the container 24. When the lever 9 reaches the upper edge of the side opening 26, it rotates AND, by means of a pull, 1 1 retracts the stopper 13 to the extreme rear position. The upper arm 14 and the gripping element 8 under the action of the spring 7 return to the initial position (Fig. 5). After the lower arm 9 leaves the hollow element of the container, the spring 12 rotates the stopper 13 until it stops 22. The locking mechanisms return to their original tension-balanced state and are ready to repeat the gripping cycle.
