Description

one

The invention relates to equipment used to service aluminum electrolysis cells.

The known machine for changing the baked anodes of aluminum electrolysis cells, which is a gantry crane, on the right and left sides of which is mounted a device for exchanging the anodes, made in the form of a vertical rotary column, bearing on itself a carriage with a telescopic horizontal bar, equipped with a fork gripping the anode, and provided with mechanical actuators for rotating the column, raising and lowering the carriage with the rod and horizontal movement of the rod. In addition, the machine has a winch yKocnHv with a winch, as well as a device for contacting the connecting leads of anodes with an anode busbar, made in the form of a fixed beam and a carriage moving along it, on the console of which a column is vertically mounted with a key connected to mechanical drives.

The proposed machine is characterized in that the device for moving the anodes is made in the form of a trolley mounted on a crane with the possibility of moving it from one side of the electrolyzer to the other and equipped with a rotary drive platform on which a guide column with an electrically mounted column is mounted.

a drive carriage carrying an anode gripper on it; the carriage is located inside the column, and a key for releasing and tightening the contact clips is installed outside the column and provided with a mechanism for moving it along the column.

This simplifies the design of the machine, improves its performance and reliability.

FIG. 1 shows the proposed machine, side view; in fig. 2 the same, front view; in fig. 3 is a device for rearranging anodes, front view; in fig. 4 - the same, side view; in fig. 5 - the same, top view.

The machine contains a portal 1 with a drive 2 moving along the rails 3 along a row of electrolyzers, a device for swapping the anodes 4 and a key 5 for releasing and tightening the contact clamps. On the portal frame

wheels 6, buffer 7, current collector 8, control cab 9, cabinets with electrical equipment 10.

The device for moving anodes contains a trolley 11 with a drive 12 of movement

along I-beams 13 of the portal, laid across the longitudinal axis of the electrolyzer. On the frame 14 of the trolley, a rotary platform 15 is installed on which the lifting and turning mechanisms are located, as well as a turntable 16. The turn mechanism includes an electric motor with an integrated brake 17, connected by a gear coupling with a worm gear 18, and gear 19 is fitted on the low-speed shaft. coupling with a gear wheel rigidly connected with a movable ring of the bearing circle. The cable drum 20 of the lifting mechanism at one end rests on the low-speed shaft of the crane gearbox, 21, and the other is mounted in a rolling bearing.

The motor 22 is coupled to the gearbox 21, having a brake coupling half and an electromagnetic brake 23 at the second end of the high-speed shaft. A torsion strength limiter 24 and a balancing block 25 are attached to the platform in the lower part. inside which, on rollers 27, carriage 28 moves, carrying two blocks 29 and gripper 30 on itself. Rope 31 comes off drum 20 and bends around blocks 29, as well as equalizer block 25. On column 26, it is mounted from its outer side to Key 32, equipped with a mechanical drive 33 for vertical feed. Installing the key on the anode swapping column allows the movement of the carriage 11 to aim the key on the head of the main clamp.

The machine works as follows.

The mechanisms are controlled from the cab 9. The machine spreads along the rails and stops at the replaceable cinder 34 or anode 35 installed on the outside of the electrolyzer serviced by the size of the machine on the floor of the workshop. The trolley 11 is moved from one side of the electrolyzer to the other in the transport gap between the electrolyzers or in the middle passage. After stopping the machine at the electrolyzer by turning on the mechanism for lifting and moving the cart, the grip 30 is inserted under the flange

butt 34 ends. The head of the key 32 is aimed at the main clamp bolt, unwinding its butt 34 is released. By means of the mechanism for lifting and moving the carriage, the calcine is removed from the electrolyzer and transferred to the extreme position on the machine, after which it is rotated 180 °, installed on the floor of the workshop or in a special pallet. The gripper 30 is released from the calcine and hooks the new anode, the carriage moves to the electrolyzer and sets the anode in place of the removed calcine. The key 32 tightens the clamp, after which the gripper 30 is released from the anode and the carriage moves to its original position. So, move to the next electrolyzer, the machine will change the anodes.
