In the situation that explosion-proof switch is controlled high concentration, in order to facilitate test and maintenance, the general method that control switch is set that adopts of this class switch, control switch can operate on flameproof enclosure, and the prime at isolating switch, parallel with isolating switch, isolating switch only is responsible for the whether charged of major loop like this, and the power supply of control loop is controlled by control switch separately; Thus, in maintenance and when test, can only allow the control loop of the low pressure that is easy to break down get electric work, the high pressure major loop is in off-position, has increased fail safe and operability.
But realize the above-mentioned functions design, often contain an isolating switch, will increase a locking source with the Qianmen in product, traditional linkage mode be between the door-opening mechanism at isolator operation handle and Qianmen, between the door-opening mechanism at control switch handle and Qianmen, deadlock lever to be set all and realize, therefore, structure will be more loaded down with trivial details during a plurality of isolating switch.
Summary of the invention
The purpose of this utility model is to provide a kind of compound mine explosion-proof switch door opening electrical outage locking device, and linkage mode is fairly simple and effective.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of compound mine explosion-proof switch door opening electrical outage locking device comprises deadlock lever and Breech block, and described deadlock lever comprises deadlock lever A and deadlock lever B, deadlock lever A and deadlock lever B vertical locking mutually.
compare with prior art, Mineral Product Flame-Proof Switch door opening electrical outage locking device of the present utility model, in the situation that explosion-proof switch is controlled high concentration, utilize two deadlock levers of mutually vertical locking to coordinate, the door opening electrical outage locking of realization to Breech block on the Qianmen, be the door-opening mechanism at Qianmen only need and the isolator operation handle between deadlock lever is set, just can realize the door opening electrical outage locking of Qianmen and two power transmission operating grips, guarantee first disjunction control switch, the cutting-off controlling ring current, again isolating switch is got to stop position and make the major loop outage, then the order that just can open the door, therefore, when a plurality of isolating switch, the linkage mode of locking device can be fairly simple and effective.
