Description
Technical field
The utility model is related to coal mine equipment field more particularly to a kind of mine explosion-suppression and intrinsic safety type enabling interlocks.
Background technology
Switch interlocking mechanism is a kind of common 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 emergency stop latch buttons
Interlocking, i.e., must press latch buttons can just pull disconnecting switch, and when pulling disconnecting switch in this way, contactor is closed by emergency stop
Button power-off is locked, so as to fulfill electric blocking.
But if maintenance personal forgets to press emergency stop latch buttons, directly open door lock, then it can cause safety accident,
Therefore it must be provided with interlocking between emergency stop latch buttons and door lock, many interlocks design currently on the market is complicated,
Higher price.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of the prior art and provide a kind of scientific structure design to close
Reason, a kind of relatively low mine explosion-suppression and intrinsic safety type enabling interlock of price.
To realize that the utility model provides following technical scheme：A kind of mine explosion-suppression and intrinsic safety type enabling interlock, it is main
To include substrate, turn left on the substrate from the right side and be sequentially connected fanning strip, handle set, lock and badge block；The handle
Handle axis is equipped in seat, handle copper sheathing is additionally provided between Handle axis and handle set, clamping block is connected below the handle set, it is described
The side insertion handle of clamping block；The lock includes locking seat, is equipped with locking pin in the locking seat, the locking pin passes through
Locking seat is worn, the front end of locking pin is equipped with convex block, and compression spring is cased on one end locking pin far from convex block, and the convex block is embedded in badge
In block.
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 washer are connect with clamping block bottom, and the leaf spring is equipped with horizontal part and curved portion, horizontal position in the bottom of clamping block,
Curved portion one end and handle contact.
Preferably, the handle copper sheathing is equipped with explosion suppresion surface with Handle axis contact position.
Preferably, the lock is in same horizontal line with clamping block.
The usefulness of the utility model：The present apparatus is simple in structure, and price is relatively low, saves cost for enterprise well,
Handle copper sheathing is equipped with explosion suppresion surface, Handle axis safety higher in rotation process with Handle axis contact position.
