Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to metallurgical equipment technical field, concretely relates to a kind of electrolytic plate hoisting device. BACKGROUND
[0002] In the wet metallurgical electrolysis process, the plate as the core carrier of electrolytic reaction, need to be extracted from electrolytic cell periodically to strip the deposited elemental metal, and re-inserted into empty plate to maintain continuous production. The traditional hoisting device generally uses the operation mode of one-time extraction of whole-slot plate, that is, all the plates in the electrolytic cell are lifted at the same time by the lifting tool. However, this mode has the following serious defects: after the whole-slot plate is extracted, the electrolytic cell is in a completely empty slot state, which causes the interruption of the electrolytic current path, and each interruption causes at least production stoppage, seriously damaging the continuity of production. To avoid the above risk of disconnection, some enterprises try to realize partial hoisting by reducing the number of hooks, but this method requires repeated operation, and after each "old extraction-new insertion" operation, the hoisting device needs to be repositioned to the next station; the whole plate needs to be cycled several times.

[0005] Further, at least two groups of driving assemblies and corresponding hook groups are provided on each side of the lifting frame.
[0006] Further, a guide seat for moving and guiding the moving rack is fixedly installed on the lifting frame.
