Problems solved by technology
The existing elevator safety system can only prevent some accidents, for example, it can only prevent the elevator from overspeeding or accidental movement. In order to ensure the safety of the elevator, it is often necessary to install multiple sets of safety systems on the elevator. The overall structure is complicated, which is not conducive to reducing production costs and maintenance costs

The invention discloses a system for preventing falling, overspeed and accidental movement of an elevator. The system is characterized by comprising an accidental mobile device which rises or falls synchronously with a car, a double action safety gear, a two-way speed limiter and fixed guide rails extending vertically; the accidental mobile device and the two-way speed limiter comprise rope pulleys, and meanwhile steel wire ropes are connected between the rope pulleys; the double action safety gear is arranged between the accidental mobile device and the two-way speed limiter, so that the system has the functions of preventing falling, speeding up, and accidental movement when the car stops; compared with the prior art, the system has the advantages of multiple functions, and high safety and reliability; and a single safety device for achieving a certain function is not required, and the cost is reduced effectively.
Description
technical field [0001] The invention relates to the technical field of elevator equipment, in particular to an elevator anti-falling, overspeed and accidental movement protection system. Background technique [0002] In today's society, most high-rise buildings such as residential buildings and office buildings are equipped with elevators, and elevators have become an indispensable tool in most people's daily life, and the safety of elevators is becoming more and more important. The abnormal operation of the elevator usually includes speeding up, speeding down, and sudden falling or rising when the elevator door is opened. If effective preventive measures are not taken, it may cause serious safety accidents. The existing elevator safety system can only prevent some accidents, for example, it can only prevent the elevator from overspeeding or accidental movement. In order to ensure the safety of the elevator, it is often necessary to install multiple sets of safety systems on...
