Description
Technical field
The present invention relates to coal mine equipment field, more particularly to a kind of mine explosion-suppression and intrinsic safety type enabling interlock.
Background technology
Switch interlocking mechanism is a kind of conventional mining equipment, for controlling the break-make of electrical equipment circuit under ore deposit, is being tieed up
When repairing, door lock is opened, and interlocking releases, and door can be opened, and in general disconnecting switch mechanically has with jerk latch buttons
Interlocking, i.e., must press latch buttons can just pull disconnecting switch, and when so pulling disconnecting switch, contactor is closed by jerk
Button power-off is locked, so as to realize electric blocking.
But if maintenance personal forgets to press jerk latch buttons, directly open door lock, then it can cause security incident,
Therefore must be provided with interlocking between jerk latch buttons and door lock, in the market many interlock complex designings,
Price is higher.
The content of the invention
The technical problem to be solved in the present invention is overcome the deficiencies in the prior art, there is provided a kind of scientific structure design is reasonable,
A kind of relatively low mine explosion-suppression and intrinsic safety type enabling interlock of price.
To realize that the present invention provides following technical scheme：A kind of mine explosion-suppression and intrinsic safety type enabling interlock, main bag
Substrate is included, is turned left on the substrate from the right side and is sequentially connected fanning strip, handle set, lock and badge block；In the handle set
Provided with Handle axis, handle copper sheathing is additionally provided between Handle axis and handle set, clamping block, the locking are connected below the handle set
The side insertion handle of block；The lock includes locking seat, stop pin is provided with the locking seat, the stop pin is through lock
Reservation, the front end of stop pin are provided with projection, and stage clip is cased with one end stop pin away from projection, and the projection is embedded in badge block
It is interior.
Preferably, the bottom of the clamping block is additionally provided with protective cover and leaf spring, the protective cover and leaf spring by screw,
Spring washer and packing ring are connected with clamping block bottom, and the leaf spring is provided with horizontal part and curved portions, horizontal position in the bottom of clamping block,
Curved portions one end and handle contact.
Preferably, the handle copper sheathing is provided with explosion suppresion surface with Handle axis contact position.
Preferably, the lock is in same horizontal line with clamping block.
Usefulness of the present invention：The present apparatus is simple in construction, and price is relatively low, saves cost, handle well for enterprise
Copper sheathing is provided with explosion suppresion surface with Handle axis contact position, and Handle axis security in rotation process is higher.
