Embodiment
As shown in Figure 1 and Figure 2, a kind of protective device for preventing elevator overspeed and accidental movement of the utility model, including speed limit
Device secondary protector 1, Additional electronic security pincers 2, terraced slowdown monitoring mechanism 3 and gate mechanism for monitoring 4.The Additional electronic security
Pincers 2 and terraced slowdown monitoring mechanism 3 are respectively provided with the elevator car, can be moved along guide rail with carriage.The Additional electronic security pincers 2 are used
In locking cage guide, the ladder slowdown monitoring mechanism 3 is pulley-type arrangement, can edge by spring compression on cage guide 10
Cage guide 10 moves up and down.Velocity sensor is provided with the ladder slowdown monitoring mechanism 3, the velocity sensor is with being arranged on
The master controller 5 of elevator car top is electrically connected, and the master controller 5 is also clamped with limiter of speed secondary protector 1, Additional electronic security
2 and gate mechanism for monitoring 4 be electrically connected, be provided with microswitch 6 on Additional electronic security pincers 2, the microswitch 6 is normal
Closed switch, and connect with elevator safety loop 7, pass through the action control microswitch of Additional electronic security pincers 2.
When the elevator governor 8 that the limiter of speed secondary protector 1 is used for elevator itself fails, secondary driving elevator limit
Fast device mechanical action, limiter of speed-safety tongs linkage work, 9 gripping elevator guide rails 10 of elevator safety gear.
The elevator governor secondary protector 1 is electrically connected with master controller 5, when failing for elevator safety gear, to
Master controller 5 sends overspeed signal.Master controller obtains the hypervelocity feedback of terraced slowdown monitoring mechanism 3, control additional electron peace at the same time
2 gripping elevator guide rails 10 of full pincers, act microswitch 6, disconnect safety return circuit 7.
The gate mechanism for monitoring 4 is electrically connected with master controller 5.Gate mechanism for monitoring 4 feeds back gate and opens, master controller
5 control Additional electronic securities clamp 2 gripping elevator guide rails 10, and triggering microswitch 6 acts, and disconnects safety return circuit 7.Gate monitoring machine
Structure 4 feeds back gate and closes, and clamping of 5 Additional electronic security processed of master controller control pincers, 2 release to cage guide 10, releases to fine motion
The action of switch 6, safety return circuit 7 are connected.
The operation principle of the utility model：
1st, used as elevator safety gear second protection.
Additional electronic security pincers 2 are electrically connected with master controller 5, the signal output part of elevator governor secondary protector 1
Also it is electrically connected with master controller 5.There are following three kinds of situations when elevator overspeed is run：
（1）Elevator limiter of speed-safety tongs linkage itself is effective：Limiter of speed, which gets rid of block, makes 8 mechanical action of elevator governor, elevator
Limiter of speed 8 and the linkage of elevator safety gear 9 work, stop elevator；
（2）Elevator itself elevator governor 8 fails, and elevator safety gear 9 is effective：Elevator governor 8 gets rid of block and is not acted upon, electricity
The limiter of speed secondary protector 1 of ladder works, and the mechanical stop of elevator governor 8, makes the linkage of elevator safety gear 9 work, stop
Elevator；
（3）Elevator itself elevator governor 8 fails, and elevator safety gear 9 fails：Elevator governor 8 gets rid of block and is not acted upon, electricity
