2. Description of the Related Art Conventionally, an electrode plate transport device for electrolysis used for such a purpose has a plurality of hangers arranged in parallel with each other, and a hook rotatably attached to the hangers makes the electrode plate transportable. The board is configured to be suspended and transported.

[0003] In copper electrolysis, it is advantageous to change the distance between the poles of the electrode plates in the electrolytic cell depending on the process in order to perform efficient electrolysis. In addition, a variable hook spacing is used.

[0004] For example, Japanese Patent Laid-Open No.
As disclosed in Japanese Patent Publication No. 149984, beam members arranged in parallel with each other with hanging hooks are connected to each other by a link mechanism so as to be variable in mutual interval, and the interval is changed by a screw shaft. is there. Japanese Patent Application Laid-Open No. 3-56888 discloses an apparatus in which hangers arranged in parallel with each other with hanging hooks are connected by a link mechanism having a variable interval, and the interval is changed by an air cylinder. I have. And JP-A-3-56
In the apparatus disclosed in Japanese Patent Publication No. 688, the swing of the hanging hook is caused by parallel movement of a guide rail having a downward U-shaped cross section in which a guide roller provided on an arm attached to the upper part of the hanging hook is fitted. It is configured to do so.

[0005] However, since the above-mentioned conventional electrode plate transport device for electrolysis has been developed for use in a copper electrolysis plant, it cannot be used in a Ni electrolysis plant or the like where the environment is highly corrosive. That is, while stainless steel has sufficient corrosion resistance to copper electrolyte, Ni
The electrolyte does not have sufficient corrosion resistance unless it is titanium.

Therefore, in order to ensure smooth operation at all times by using a device as disclosed in Japanese Patent Application Laid-Open Nos. 1-149984 and 3-56688, a screw shaft, an air cylinder and the like are made of titanium. It is economically disadvantageous, for example, in that It is also conceivable to use plastic, but the air cylinder cannot be made of plastic. Also, JP-A-3-56
The rail having a downward U-shaped cross section for turning the hook of the apparatus disclosed in Japanese Patent No. 688 is not suitable for lubrication or the like for preventing corrosion.
It has many problems.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is arranged in parallel by mounting rollers provided at both ends on a frame formed by connecting a planar shape to a square shape. A plurality of beam members, a link plate having a long hole for variably connecting the intervals between the beam members, and moving the beam members located at both ends of the frame in a direction perpendicular to the direction in which the beam members extend. Two rack gears driven by the arranged motor, a hook rotatably provided at both ends of the beam member by vertically penetrating the beam member, and a portion of the hook projecting upward from the beam member. An electrode plate transport device for electrolysis, comprising a pair of guide rails having upper and lower opened shapes disposed so as to be movable in parallel by engaging guide pins erected on a connected plate.

The rack gear of the above configuration is formed of plastic in an environment having high corrosiveness.

[0010]

Since the electrode plate transport device for electrolysis of the present invention is constructed as described above, the two rack gears are operated so that the beam members located at both ends of the frame are made to have the length of the long hole of the link plate. If it is moved outward as much as possible, the mutual spacing of the hooks provided on the beam member is widened, and it is possible to cope with an electrolytic cell having a large distance between the poles. Conversely, if the two rack gears are fitted with a beam member as long as the length of the long hole of the link plate is allowed, the mutual distance between the hooks becomes small, and the electrode distance can be reduced.

The operation of opening and closing the hook when lifting or hanging the electrode plate can be performed by moving a pair of guide rails in parallel.

Since the beam member is moved by the rack gear, the beam member can be moved in a certain direction without a guide having a sliding portion for guiding the beam member in a certain direction.
Further, the rack gear can be made of plastic which does not corrode. In addition, since the guide rail for rotating the hook is open at the upper side, visual inspection can be easily performed, and lubrication can be easily performed to prevent the progress of corrosion and incomplete operation.
