Description
Technical field:
Operation restraint device field when the utility model relates to tracking-driven elevator abnormal running, is specifically related to a kind of elevator abnormal running fender guard.
Background technology:
In modernization big city, elevator, as the vertical transportation transportation means in building, has become the requisite life production facilities of people's life and work.The safety of elevator is public concern day by day.
Elevator stopping device is one of important fender guard of elevator.Roughly be divided at present following a few class:
Drg: this is the main shutdown feature of elevator normal operation, is also the main shutdown feature when elevator generation irregular operating.
Safety tongs and velocity limiter rope gripper: this is to make when the operation of elevator generation supervelocity the device that forces elevator to stop by force.
In addition, make the protection device for over-speed ascending for elevator of over travel operation and the energy disperser on travel of elevator (lift) top.
But the elevator constantly occurring in recent years slips car accident tells us: work as misfunctioning of brake, braking force is less than rated value, elevator slips car but speed be no more than command speed, just may open the door and slip car, at this moment, misfunctioning of brake can not make elevator stop, and safety tongs is because elevator speed surpasses command speed out of reach service conditions, and up overspeed governor mainly makes to slip the elevator of car by standard and underspeeds.So elevator is in complete runaway condition, and the out of control movement of elevator under door opening state.To there is at door place, the Room accidents such as door folder people.
