Key exchange device for interlocking device of safety accident prevention key that is easy to operate

摘要

The present invention relates to a key exchange device of a safety key exchange box for exchanging a key for safety of a high-pressure generator for converting a breaker AC of a shut-off box into DC, and a safety accident prevention key for opening a door of a manhole in the electrostatic precipitator The key exchange device can easily and easily operate a plurality of keys simultaneously as a single key.;Generally, the key exchange apparatus unlocks a plurality of manhole door keys to unlock the plurality of manhole door keys, and then unlocks the keys of the manhole door to unlock them from the key exchange apparatus, or to couple each key to the key exchange apparatus, Since the key of the manhole door needs to be locked as a single key, it takes a long time to change the key, and the whole key must be turned each time, which requires cumbersome operation, which shortens the working time in the manhole door. There is a problem that a personnel accident or a large electric accident occurs due to failure to properly perform the electric work to be performed.;The present invention is a lever having a rack gear, a pinion gear, a lever plate, and a hinge pin installed between a single key and a plurality of keys, so that the pivoting rods of the lock bundle to which the mutual keys are coupled are interlocked, If this key is not combined, it is impossible to operate, thereby preventing a personnel accident or a large electric accident, and it is troublesome to turn a single key so that a plurality of keys are simultaneously rotated, The time for working in the manhole is lengthened so that the electric work can be done with care to prevent personnel accidents or large electric accidents.
