SU470185A1 - Device for transposing anode pins of aluminium electrolyzer - Google Patents

Description

Suspension 15 is pressed to the extreme lowest position by spring 21. With suspension 15, rod 22 is connected, passing through the hole in rod 3 and connected to latch I. Base 12 for transfer through cup 13 of steep pin to its anode pin. The gripping tabs 17 transfer the axial force to the pin and hold the pin removed from the anode in the gripping organ. To limit the vertical stir, the gripping legs relative to the hinge 15 serve as protrusions on the legs, covering the side faces of the suspension.

The latch 11 includes an electromagnet 23, the bark of which is connected to the stop 24 by means of a bar 25, two tons of 26 and two pairs of springs 27 and 28. The stop 24 moves together with the core of the electromagnet 23 in the horizontal plane and can fit under the collar of the sleeve 29 fixed at the top of the rod 22.

The gripping member 1 mounted on the rod 3, by moving the crane bridge of the cargo carriage together with the rod 3, adjusts along the axis of the anode pin and lowers onto its head until it stops. When the bald face of the anode pin coincides with the inlet groove of the glass, the bar further lowers and the gripping organ is put on the head of the anode pin until it stops. When the glass is put on the head of the anode pin, the tabs 17 are moved apart by the head of the anode pin and enter into its slot under the influence of the springs 19.

When lifting the rod 3, the legs 17 together with the suspension 15 lower relative to the glass 13 and the anode pin is wedged in the gripping organ. At this time, the stop 24 with the bark of the electromagnet 23 is in the initial position and does not interfere with the vertical movement of the rod 22 and the associated suspensions 15 and gripping legs 17.

Thus, when the rod 3 is rotated and raised, the torque and axial force are transmitted to the anode pin. The limit switches 10 and the stops 9 mounted on the gearbox 4 limit the angle of rotation of the rod 3, since the design of the steel-aluminum anode pin installed in the body of the anode allows it to rotate only at a certain angle.

After removing the anode pin from the anode or cassette, transferring it and placing it in a cassette or anode, the anode pin is lowered to the anode pin to release it from the gripping organ 1. At the same time, the rod 3 with the gripping body 1 continues to descend, and the suspension 15, located inside the gripping body, together with the tabs 17 and the stem 22, are raised relative to the base 12 by the amount of the axial stroke. To remove the gripping organ from the head of the anode pin is included

Electromagnet 23. When this stop 24, mounted on the bark of the electromagnet 23, will go under the collar of the sleeve 29 mounted on the rod 22.

When the gripping organ is raised, the stop 24 holds the rod 22, and with it the node 15 with the gripping legs 17 in the extreme upper position, which allows the legs 17 to move apart and release the head of the anode pin.

After the electromagnet 23 is turned off, the stop 24 with the bark will not be able under the action of the springs 27 and 28 to come out from under the collar of the sleeve 29, which is exerted by the force of the spring 21. With the subsequent lowering of the gripping body on the head of the anode pin up to the stop, the sleeve of the sleeve 29 slightly raises and releases the stop 24, which under the action of springs 27 and 28 will take its

the initial position together with the electromagnet core 23. The gripping organ engages with the anode pin.

When transferring the anode pin and when it is randomly supported, the anode pin does not

disconnects from the gripping body, since the stop 24, which is in its initial position together with the electromagnet core, cannot fix the rod 22 with the suspension 15 and the gripping tabs 17. If the electromagnet 23 is accidentally pressed when the anode pin is suspended, the emphasis 24 stops up collar of the sleeve 29. So that at this moment the electromagnet 23 winding does not burn and that its measles completely vt zero into the coil, the bar 25 moves along the fixed at this moment tam 26 by the magnitude of the core stroke and compresses the safety springs 27. a wadded organ of the suspension 15 ensures reliable operation of the device when the anode pins are swapped.

The design and arrangement of the electromagnetic lock simplifies the supply of current to the electromagnet 23, which in this case is carried out by a flexible cable, and increases the service life of the gripping tabs 17, since they can be made of durable heat-treated magnetic steel.

In addition, the design of the gripping body 1 with the suspension 15 and the removed electromagnetic lock ensures that the gripping body is pushed all the way onto the anode pin head, which increases

device performance and provides a clear zapamaniya paws 17 in the grooves on the head of the anode pin.
