Description

Known gripping device for barrel loads, suspended on the hook of a crane. It is made in the form of a sling with two spring-loaded hooks, thrown over the drum chimes.

This device requires the removal of snails manually. In addition, when a ratchet frame is lifted by a crane, the released ratchets often hook on the drums of the drums and disrupt the normal stowage of the drums.

In the proposed gripping device, hooks with their shanks are inserted into cylindrical bodies with springs mounted in them, interacting when lifting the load and removing it with fork-type pushers hinged in the hooks mouths. Thanks to the proposed device, the grippers are mechanized to uncouple the barrels after unloading, which frees the workers occupied in the installation and does not disturb it when the frame with the grippers is raised.

The drawing shows the capture device.

The hook / enters with its shank into the housing 2 closed on one side. In the case there is a spring 3, fixed at one end by the case, and on the other - with a thrust washer 4 and pin 5 mounted on the hook shank /. A pusher 7 is put on the hook pivotally on the axle 6. In the upper part of the body, a dog-stop 9 is mounted on the hinge 8, which when lifting the barrel drops over the protrusion 10 of the pusher. The bracket 1 is welded to the body, with which the self-gripping hook is hooked to the cable or rope 12.

If the hooks are hooked over the chime drum and the tension of the cable or rope threaded through the bracket 11, body 2, compressing the spring 3, will move along the hook shank. Simultaneously with the housing, the stop 9 will move and drop over the projection 10 of the pusher 7.

When lowering the barrels at the place of unloading and loosening the cable or rope, the spring 3, unclenched, will move the body 2 with the shank attached to it. Last, pushing the pusher 7, frees from the hitch the hook with chime
