SU14572A1 - Crane attachment for emptying the bucket - Google Patents

Description

The invention relates to devices for emptying a bucket formed by two articulated pivots.

In the proposed bucket defrosting device, it is intended to achieve by using a bracket fixedly attached to the boom, with hooks fixed to it and equipped with counterweights, which pick up the bucket under the action of the associated rod and automatically open it.

The schematic drawing shows a crane with the proposed fixture, with the top showing a raised empty bucket, and the bottom showing a filled bucket ready for lifting.

A bracket 4 is attached to the boom of the crane, at its top, on which the hooks 7, 7 are turned pivotally at points 6, 6 facing each other and made in the form of a crank lever, with counterweights 8, 8. To the ends 9, 9 of one of the knees 7, 7 are attached, through the blocks 10 and 11, which are thrown with flexible rods 12 and 13, which at point 14 are connected into one rod, which is thrown over the block 15 and fixed on the lever 16,

The bucket 17 consists of two, hinged at point 18, flaps, which are engaged with each other by turning on the axis 19 of the latch 20, fastened by means of a rod 21 to one of the brackets 22, 22, which are hingedly attached at points 23 to each of the wings bucket 17. The bucket 17 is held in a closed state due to the pressure produced by the end of the rod 21 on the shoulder of the latch 20. On the hinge 18 there is a reinforced cross member 25 equipped with an arc 26, by means of which the bucket 17 is suspended from the crane hook 27.

For convenience of filling the bucket 17, the brackets 22, 22 are retracted to the position 1, 1, after being filled, they are shifted to the position 2, 2 and the hook 26 is grabbed by the hook 27. 7, 7 to position 3, 3 and using the hoisting rope 5 of the crane, raise the bucket 17 to a height sufficient to catch the hooks 7, 7 of the brackets 22, 22 of the bucket 17. Then brake the crane and, lifting the lever 16 up, relax g 12 and 13, thanks to which the hook 7, 7, the action of counterweights 8, 8, will begin to draw closer and pick up the bucket 17 by the brackets 22, 22. In this

time the brake is turned off, and the krail rope 5 will begin to lower the filled bucket 17; the latter hangs on a hook x T, 7 and by the action of weight will turn brackets 22, 22, one of which sweat is not rod 21. Bar 21 acts on the shoulder of the harness, Christmas trees 20, thanks to which the latter rotates on axis 19 and disengages the flaps, which, turning on axis 18, the bucket l7 will be opened for emptying. After that, the bucket 17 is lifted by means of a lifting rope 5; tension tg 12,13, using the lever 16, release the brackets 22, 22 from the hooks; 7 ,, 7 and lower the bucket 17 for filling.

The subject of the patent. Adaptation to the crane for emptying the bucket formed

two articulations connected with each other, characterized by the use of arms suspended from bracket 4 attached to the boom of the crane at its top, two reversible to each other and made each in the form of a crank arm, hooks 7, 7c. with counterweights 8, 8 deviating each other from a friend when tensioning a flexible rod 14 connected to them and converging when loosening it, which hooks serve to lift the raised bucket 17 by the brackets 22-22, pivotally attached to each of its gauges so that during the subsequent lowering of the lifting rope vtomaticheski disengage from each other by deflection aligners binding of latch 20 and thereby dotsustit dehiscence ladle.
