Description

This invention relates to the mechanization of unloading operations with bulk and bulk cargoes. Known gripping devices for lifting and unloading kubel, containing lines, equipped with rings for attachment to the hook of the lifting mechanism and grips, made in the form of loops and interacting with the hooks kubel. However, the known devices require manual labor to perekrepleniya slings when opening kubel, which reduces the effectiveness of such devices. The purpose of the invention is to provide an automatic release of the device from the tube after it is unloaded. This is achieved by the fact that, in the proposed device, on the loop of each sling there is a pivoting, spring-loaded lever, which interacts at one end with the hook of the kubel, and the other with the L-shaped anchoring fixed on the link of the sling. To prevent premature slipping of the loops from the hooks on the cheeks of the latter, it is advisable to strengthen the pivoting spring-loaded dogs. FIG. 1 shows the described device with a cable, general view; in fig. 2 - the same, side view; in fig. 3 — swivel hook with self-disengaging device; in fig. 4 is a view along arrow A in FIG. 3; in fig. 5 is a section along BB in FIG. 3. The Kubel, for lifting and unloading of which the proposed device is intended, comprises hingedly mounted on a frame with racks / two half bows 2 and 3, directed openly partly to one another, hooks 4 connected by fingers 5 and facing one another, and hooks 6, welded to the sides of the half-bow 2 and 5. Swivel paws 7, attached to the hooks with their fingers 8, help the springs 9 to prevent the front 10 and side 11 chains of the slings from falling out. Chains 11 are made longer than chains 10. At the end of each of the lines, a self-engaging device is installed, for which the ears 12, welded to the last link 13 of the line, have a pivot arm 15 attached to the finger 14, which is pressed to the limiter 17 by the spring 16. The lever 15 communicates at one end with the hook of the kubel, and the other with the L-shaped stop 19 fixed on the penultimate link 18 of the sling, which cocks the lever 15 and holds it in this position until the sling hooks with the hook and rises. The device works as follows. When lifting the kubel, the side chains // sag and hold on the hooks, and the end chains 10 tighten and, pressing against the upper part of the hook mouth, release the rotatable spring loaded dog 7.

To unload the kubel, it is preliminarily lowered onto the unloading platform, the chains are loosened and come out of the hook groove under the action of its own weight and the pivot arm 15. When re-lifting, the side chains 11 open the half-heads 2 and 3, unloading the kubel. When tensioning the side and end hooks, the pivoting dogs 7 are folded back, releasing the hook mouth, after which the floor of the bucket 2 and 3, freely turning on the fingers, are closed, and the chains, similarly to the end hook, come out of the hook groove.

The subject matter of the invention 1. A pick-up device for lifting and unloading a kubel comprising slings provided with rings for hanging on a hook of a load-lifting mechanism and grip made in the form of loops and cooperating with a hook of a kubel, characterized in that with the aim of automatically releasing the device after unloading it from the kubel, on the loop of each sling, the rotary spring-loaded lever, which at one end interacts with the hook of the kubel, and the other with the L-shaped anchoring fixed on the link of the sling, strengthened.

2. A device according to claim 1, characterized in that in order to prevent premature slipping of the loops from the hooks, rotatable spring-loaded dog dogs are fixed on the cheeks of the latter.
