Lift car anti-sliding control circuit

The utility model discloses a lift car anti-sliding control circuit which comprises a control system and a rope clamp. The control system is connected with the rope clamp through a wire and comprises a speed limiter ascending overspeed control loop and a rope clamp control loop. The speed limiter ascending overspeed control loop is in parallel connection with the rope clamp control loop, and the rope clamp control loop comprises a flat layer inductive switch, a hall door limiting switch and a lift door limiting switch. The hall door limiting switch is in series connection with the flat layer inductive switch after being in parallel connection with the lift door limiting switch, and the rope clamp is connected with a rope clamp movement feedback module and transmits movement feedback signals to the rope clamp movement feedback module. Original facilities of an elevator are utilized for the lift car anti-sliding control circuit, the rope clamp control loop in parallel connection is added, the modification based on an original structure of the elevator is small, the lift car anti-sliding control circuit is convenient to implement, causalities caused by elevator sliding can be avoided, and system safety is improved.
