The anti-shear protective device of elevator permanent-magnet hurted sb.'s feelings.
Background technology
It being continuously increased with the development of the city with modern key city population, high-rise building continues to bring out, and at a high speed
Elevator is the important tool of high-rise building vertical transport, is the essential vehicles of Modern Urban Living.Cut-off 2015
Shared 425.96 ten thousand, the elevator in the end of the year whole nation, under so big ownership, elevator safety accident also gradually increases, wherein being made because slipping ladder
Into security incident account for wherein very big proportion, huge threat is brought to the security of the lives and property of the people.
The safety guard for shearing accident in presently relevant data document in relation to anti-slip ladder and personnel is segmented into two classes,
One kind is not change the mechanical structure of elevator, and by setting independent detection device and control device, traction machine is controlled,
Prevent elevator from slipping ladder and accidental movement；The another kind of mechanical movement mainly opened or directly opened using gate by detecting car
Make the brake apparatus specially set or mechanical card resistance device work, prevent the car accidental movement in gate opening process.
First kind exemplary is patent（Application number CN201210219167.8）Disclosed in a kind of elevator safety protection
Method.When elevator stops at area, the sliding situation of lift car is monitored in real time.If it is judged that the brake force because of band-type brake device
Square deficiency causes car to slide, then slides speed by what the diphase winding of inverter short circuit motor carried out that dynamic brake slows down car
Degree, while force to close the door.Elevator is again started up after elevator door is closed, and leaves for the terminating layer along car glide direction, and elevator stops
Shutdown state is kept afterwards.The invention reduces the risk of car sliding under conditions of system hardware is not increased, and terraced protection is slipped in realization.
