The cooperation of dead bolt, it is ensured that the modular feeding switch in flame proof shell can be just opened when the certain safe distance of main circuit is exited in disengaging
Open Qianmen.When the chopper in modular feeding switch is in "on" position, (permutator connects control loop, quiet spring needle
Seat and spring needle stand closure of moving), the immovable modular feeding switch of propulsion drawing-out mechanism.When chopper is in separating brake (
Quiet spring needle stand is separated with spring needle stand of moving, and permutator disconnects control loop), propulsion drawing-out mechanism effect propulsive mechanism drives
Modular feeding switch departs from main circuit, only could clash into locking when modular feeding switch departs from main circuit certain distance
Locking key in mechanism, makes locking key move into lock housing, while dead bolt is also moved into lock housing, Qianmen can be opened；If modular
Feeding switch depart from main circuit for be not up to this apart from when, modular feeding switch cannot clash into locking key, and locking key is also just without normal direction
Move in lock housing, outside lock housing, Qianmen is still in lock-out state with flame proof shell to dead bolt.
Switch in flame proof shell is combined by the conversion equipment in interlocking mechanism will permutator and Tai Zhen mechanisms group
Be integrated coordinated type, reduces the shared spatial volume in flame proof shell of switching mechanism, reduces outside flame proof shell so as to reach
Volume makes its modular purpose, while achieving the purpose of the efficient disjunction of feeding switch by conversion equipment, improves work effect
Rate, it is ensured that worker safety, cost-effective.And Tai Zhen mechanisms are using eccentric control tripping spring needle stand and quiet spring needle stand
Switch movement travel, simple structure are safe and reliable.Housing and setting latch plate between spring needle stand of moving in Tai Zhen mechanisms, makes
Spring needle stand of only must moving is in and quits work under (i.e. separating brake) state, and latch plate could be released with moving on spring needle stand of moving
Modular feeding switch is blocked, propulsion drawing-out mechanism could act on modular feed by the screw rod of propulsive mechanism and open
Close, modular feeding switch is moved, it is to avoid under working, artificial compulsory withdrawal causes electrically feeding switch
Accident dangerous or sound spring needle stand is damaged.Therefore under the setting of latch plate ensure that feeding switch in working order,
Propulsion drawing-out mechanism can not be with screw rod interconnection function.
Propulsion drawing-out mechanism allows the modular that staff is opposite in flame proof shell by the outside of flame proof shell
Feeding switch is advanced and is exited effect, it is ensured that staff's personal safety.By the spanner rotating shaft on push-pull bar, complete
Into the connection or disconnection of modular feeding switch and main circuit, though exit or progradation in break down adhesion cause quick-fried
Fried, its feeding switch is also in explosion-proof chamber body, is hedged off from the outer world, and gives full play to the effect of flame proof shell, it is ensured that worker safety.
One end on push-pull bar on the outside of Qianmen is provided with annular stop platform, and steel bushing inwall forms step with copper sheathing end door
Face, is provided with spring between annular stop platform and step surface, push-pull bar is slidably matched with copper sheathing inwall along the axis of steel bushing.Pass through
The setting of spring can ensure that the spanner being placed in flame proof shell keeps certain distance with rotating shaft, during connection, only need to pass through in outside
Propulsion push-pull bar, you can complete the connection of spanner and rotating shaft, while ensureing safe, simple and fast.In steel bushing and push-pull bar
The part for exposing Qianmen is provided with protection cap bag, prevents erosion of the external environment to steel bushing and push-pull bar.
Latch-up protection mechanism is additionally provided with blocking mechanism, prevents flame proof shell from closing Qianmen without modular feeding switch
Maloperation.When main chamber is without module feeding switch, backplate is rotated so that backplate is acted on locking key, compression locking key is (so that dead bolt
Return in lock housing) unlocking, prevent maloperation.
