SU590239A1 - Multijaw grapple for handling ferromagnetic materials - Google Patents

Description

The image relates to a blast and a hoisting machine, and it concerns grab mechanisms with electromagnets used to process ferromagnetic materials, such as scrap metal, chips, etc.

The maxillary grapples are known to be an electromagnet moving relative to dorlus.

However, the known design is complicated and does not guarantee the direction of movement of the electromagnet, but rather preserves the necessary direction of the axis of the magnetic flux, which leads to a decrease in the gripping capacity of the grapple.

Closest to the invention. is a grapple containing a housing and a .BEDGE connecting to it and the jaw. movable electric magnit 2.

However, this device also does not provide the necessary directionality of the movement of the electromagnet.

The purpose of the invention is to increase the scooping ability of the grapple with the need to ensure that the movement of the electromagnet and the synchronous 1c connection between it and the jaw are imbalanced.

For this purpose, the electromagnet is connected to the housing by means of a multi-stage telescopic rod, and to the jawbone by a polysilastic system.

FIG. I depicts a grab with an iB electromagnet of closed lolization, general view; in fig. .zhe, in the opened lolo .Zhe1N «and.

The grab consists of a housing, 1, a hydraulic pumping station, casting hydraulic cylinders 2, and a lifting electromagnet 3. The housing is composed of a jaw 4 and a lolispastny system 5 with a block of blocks 6 and 7 fixed to the corrus and respectively, jaw x . Worm and Corlus are rigidly connected between

a "multi-stage telescopic rod 8.

When deployed, a drift electromagnet suspended on the ropes of the polyopast system, 5, due to the approaching of blocks 6 & 7, is lowered to the level of the lower edge: open jaws. In this position, the grab with the electromagnet is lowered to the upper level of the ferromagnetic load, subject to gripping. At the same time electromagnet 3 and

body 1 due to the telescopic connection maintain coaxiality and parallelism relative to each other, which contributes to the required most effective directionality of the axis of the magnetic lotto of the electromagnet and an increase in the volume of the captured load. Behind

The effect of the magnetic field of the electromagnet, the value of the particle of the ferromagnetic rod being gripped, is related to the electromagnetic magnet at the loading and lifting time of the grapple. When closing the grab, the jaws 4, buried in the material, capture additional volume.

Thus, due to the action of the electromagnet and the jaws of the grapple, the volume of the ferromagnetic load is greatly increased.
