Abstract

The invention discloses a linear drive device, a safety tongs device and a control method of an elevator system. The linear drive device comprises a magnetic conductive device and a magnet, wherein the magnetic conductive device at least comprises a first side part and a second side part; the magnetic conductive device is equipped with a sealed magnetic cavity; the magnet is positioned between thefirst side part and the second side part; the magnet at least comprises a first end and a second end; the direction of a magnetic pole at the first end is reverse to that of a magnetic pole at the second end; the first end corresponds to the first side part; the second end corresponds to the second side part; a winding coil is arranged on the magnetic conductive device; the winding direction of the winding coil is perpendicular to a direction, formed from the first end of the magnet to the second end of the magnet, in a magnetic cavity; and the magnetic conductive device is movably matched with the magnet. The linear drive device can solve the problems that a long stroke and large-torque drive are needed when electric type safety tongs return, and has good torque stability.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a linear drive device, a safety gear device and a control method for an elevator system. Background technique [0002] With the continuous acceleration of the urbanization process in our country, more and more high-rise buildings are equipped with elevator equipment, so the safety of elevator equipment is closely related to people's lives; the traditional elevator safety gear is driven by a mechanical speed limiter, but with the functional electronics With the development of safety technology, the electronic speed limiter gradually shows better functions and performance characteristics, but the matching electric safety gear products are not perfect. [0003] The existing electric safety gear reset design mostly adopts electromagnet technology; and as we all know, electromagnets are generally used in the structural range of small spacing, and the general spacing is less than 20 ...
