Abstract

The invention relates to an elevator technology, in particular to an anti-slip protection device for an elevator, and solves the problem that a slip accident is caused because the moment of a brake is inappropriately adjusted in the mounting process of the elevator, or maintenance personnel neglect to maintain the brake in the using process of the elevator. The device comprises a rope gripper, a brake verification switch arranged on the elevator brake, and a main control unit, and is characterized in that a locking hook connecting rod stretches out of one end of the rope gripper; a trigger ejector rod is arranged at the upper end of the locking hook connecting rod; a trigger pull rod is perpendicular to the trigger ejector rod; one end of the trigger pull rod is matched with a magnet ejector rod at the end of an electromagnet; and the electromagnet is controlled by the main control unit. By the device, the phenomenon that a car moves when the elevator is in a stop state is avoided; a door opening signal is cut off, and a forcible door closing signal is given in case of an anomaly; and the car can be prevented from continuously moving when the elevator slips, a car door can be forcibly closed, passengers are prevented from leaving the car, and the running safety of the elevator is greatly improved.

Description

technical field [0001] The invention relates to elevator technology, in particular to an elevator anti-rolling protection device for a traction elevator. Background technique [0002] The elevator is a kind of equipment that requires a high safety factor. The design and manufacture of the elevator cannot lack the protection device. The existing elevator protection device involves all aspects of the elevator, and the safety protection design is carried out from one aspect of the elevator. For example, the patent announcement number is CN201713175U An elevator protection device, including a traction machine, a traction rope, a speed limiter, a machine room control cabinet, a car, a car guide rail and a car door, a car buffer is installed on the ground directly below the car, and a An inflatable bag is installed on the upper surface, and the inflation valve of the inflatable bag is controlled by pulling the traction rope, and the other end of the traction rope is connected with...
