Description

one

The invention relates to lifting equipment, namely, crane gripping devices for sheets hinged on rods.

A crane gripper yctpoft for sheets hinged on rods is known, containing a frame with rigidly mounted copy hooks ij.

A disadvantage of the known device is the lack of reliability due to jamming of the rods when loading sheets into the container.

The purpose of the invention is to increase the reliability of work by eliminating jamming of the rods when loading sheets into the container.

This goal is achieved by the fact that axes that can be rotated manually and fixed in the required position, bearing vertically arranged supports for the sheets, are rotatably fixed on the frame.

FIG. 1 shows a crane device for sheets hung; on the rod, a general view; in fig. 2 - the same view

from the side; in fig. 3 - a fragment of the device during the release from the load.

The device contains a frame 1, an earring 2 suspended on a load-lifting mechanism. On either side of the frame 1 there are rigidly fixed copying hooks 3, one side of which is made on the inclined part 4. On the frame 1 axles 5 with handles 6 are fixed on which stops are fixed 7

to for sheets. The frame 1 is provided with a locking mechanism 8 for fixing the positions of the axles 5.

The device works as follows.

Claims (1)

When gripping the rods 9 with the sheets 1O, the axles 5 are rotated by the knobs 6 in such a way that the stops 7 are arranged horizontally. In this position, the axes 5 2Q are fixed by the mechanism 8. After this, the hooks 3 engage the rods 9 of the sheets 10 and transport them to the place of discharge. Before unloading the sheets 10 into the container, the axles 5 are turned in the opposite direction by the knobs 6 and the stops 7 occupy a vertical position, which is also fixed by the mechanism 8. In this case, as soon as the sheets 10 touch the bottom of the container, the rods 9 begin to slide along the inclined part 4 of the hooks 3 The sheets 10 touch the stops 7. In this position, the rods 9 do not touch either hooks 3 or the stops 7, which allows the bars to be removed manually. As soon as the device is removed from the sheet, the device is raised, while the stops 7, moving up along the sheets 1O, gradually return them to a position close to the vertical one. With a further rise of the device, the stops 7 come out of contact with sheets 1O, which under their own weight stick to the bottom of the container. 7 4 Claims of invention The crane gripping device for sheets hinged on the rods containing a frame with rigidly fixed copying cargo hooks, characterized in that, in order to increase the reliability of operation by eliminating jamming of the rods when loading the sheets into the container, the frame is rotated on the frame manually and fixation in the desired position of the axis, bearing a vertically arranged stops al-sheets.
