Description

A known machine for servicing aluminum electrolytic cells with baked anodes, comprising a gantry crane with the mechanism of its movement along the rails and two stubs with winches.

Oredlozdeiiya machine differs from that known in that on the right and left sides of the gantry crane, identical devices are used for swapping anodes and "contacting the cooling-free Rods of the anodes with an anodopop bus-bar. This allows servicing both sides of the electrolysis cells, mechanizing the operations of rearranging the anodes, and contacting the current lead rods of the anodes with the back bus bar. The interrupting device can be made in the form of a vertical pivot column, laying it on itself has a carriage with a teleoconical horizontal bar equipped with a fork at the end to grip the anode, and also have mechanical drives to rotate the column and raise and lower the carriage with the bar and horizontal remesh.mesh, epi bar. The device for contacting the current-carrying rods of the anodes with the anode bus-bar can be made in the form of an unconnected beam and a movable carriage, on the console of which a column is vertically installed with a mechanical key connected to a mechanical N-drive mn.

FIG. 1 shows the kinematic scheme of the prepositional engine; in fig. 2 - left side of the machine, front view; in fig. 3 - the same, top view; la fig. 4 - right part of the car, front view; la fig. 5 - the same, top view.

The machine consists of a portal “wound”, a mechanism for the horizontal feeding of the alode, a carriage, a coloppa with a turning mechanism, a mechanism for the ajder; a1;

movement

All components of the machine are mounted on the portal crane 1. With the help of two idle 2 and two front-wheel 3 wheels the crane is mounted on rails 4, lrolol enlyh along each row of electrolyzers 5.

The machine is filled in two parts - the left and the left, which serve the left and right sides of one p Yes cell, respectively.

Mechanisms of the left and right parts of the machine

are identical to each other and perform the same functions.

The mechanism 6 for moving the machine consists of an electric motor with an adjustable rotational speed, a brake, a two-stage gearbox. The control panels for the machine and the seat 7 of the operator are mounted on the left and front parts of the machine. The mechanism 8 of the horizontal nodal anode is mounted on the beam 9 and consists of an electric motor, a brake, a worm gearbox, a torque limiting clutch and a chain 10. The value of 10 through the POWDER is connected to the immovable horizontal bar II and can move it along the rollers 12 relative to the beam. A fork 13 is fastened at the end of the rod, the pickup serves to hold the anode 14. The beam 9 is fixedly mounted on the side to the roller carriage 15. The carriage can vertically move along the vertical column 16 using the lifting mechanism 17, which is fixed on the column and consists of a vertical gearbox with an electric motor, an electromagnetic friction clutch 18 of the torque limit, a screw 19 and a nut 20, which is connected to the carriage. The column can be rotated 90 ° about its axis by the mechanism 21 of the turn. The mechanism consists of a worm gearbox with an electric motor, a sleeve MOiMCHTa 22, a screw 23 and a nut 24. The winch 25 is mounted on the top of the crane and contains an electric motor, two worm gearboxes, a drum 26, blocks 27, a rope 28, a dowel 29 and pick-up device 30. The winch with a lance serves to move new anodes from the outside of the machine to the zone of action of the rod. The device for charging and releasing the contacts consists of a mechanical key, a key lifting mechanism and a horizontal feed mechanism. The mechanical key 31 includes a vertical gearbox with an electric motor, an electromagnetic friction coupling 32. Of the limiting moment, two bevel gears 33, a hinged coupling 34, podruhl 35 and a leash 36. The rotational movement of the head of the key is transferred to the nut (or bolt ) clamping the electrolyzer, which presses the aluminum rod 37 of the anode 14 to the busbar 38. The leash 36, which is frictionally connected to the axis of the head of the key, serves to rotate the chuck of the clamp into the corresponding polonenie; The key lifting mechanism 39 consists of an electric motor with a worm gearbox, axle shaft 40, screw 41 and nut 42. The mechanical key is mounted on the bracket 43 and together with it can move vertically with the screw 41 and the guide. The mechanical key guide and key lifting mechanism are mounted on the carriage 44. The carriage can be moved horizontally on its rollers 45 along the fixed beam 46. With the help of the mechanism 47 of the horizontal key supply, which consists of an electric motor, a brake, a worm gear. limit torque couplings and chain 48. The mechanism 47 is mounted on the top of the gantry crane. The chain 48 is connected via a lead to the carriage 44. Depending on the need for servicing the left or the left side of the electrolyzer, the operator switches to the appropriate machine control panel. The car drives up to the electrolyzer, in the stower it is necessary to change the worked anodes. On the outer side of the serviced electrolyzer, outside the dimensions of the machine, new anodes are pre-installed on the floor of the workshop, one of which is suspended by the vertical end of the aluminum rod on the boom 29. The head 35 is adjusted to the bolt (nut) of the contact clamp due to the vertical and horizontal movements. At the same time, the operating speed of the machine is adjusted by changing the revolutions of the electric motor (movement drive bar. Mechanism 21 turns the column turns 90 together with the carriage, bar boom. The fork is inserted into the slot of the anode to be replaced. After opening: the push clip (i.e. releasing the aluminum / aluminum rod 37 of the anode) 11 removes the burned anode from the working area of the electrolyser. By rotating the colony 16 to 90 the anode is moved out of the electrolyzer and landed on the shop floor grating. After that the bar moves to the bottom The position and the new anode are borne by 29 and placed on the floor opposite the fork of the rod. The wire is inserted into a new anode, the IKOTOI-like 11 is turned, turned 90 and fed to the place of the extracted one, where it is adjusted in height and then fixed on the tire 38. Next, the machine moves to the next anode and the whole process, the replacement of the anodes is repeated again. New and burnt anodes are placed and removed from the floor of the workshop with a bridge crane or a. Loader. Invention 1. Machine for servicing Aluminum electrolysis cells with bored anodes. including a gantry crane with a mechanism for moving it to the rails and two barbs with winches, characterized in that, in order to service both longitudinal sides of electrolysis, mechanization of anodes permutation operations and contact of the anode lead current rods, on the character and the left side Portal crane mounted identical devices for non-installation of anodes and contact of the current-carrying rods of the anodes with the anode busbar.

These carriers carry a carriage with a telescopic horizontal bar, equipped at the end with a fork for gripping the anode, and equipped with mechanical drives to rotate the column, pickup and lower the carriage with the bar and horizontal spacing. 3. A machine, characterized in that the device for contacting the current-carrying rods of the anodes with the anode busbar is designed as a fixed beam and mixed, made of a carriage along it, and the console of which is vertically installed a column with a mechanical key connected to the -mechanical drives.
