Elevator anti-shear protection device and control method thereof

Abstract

The invention discloses an elevator anti-shear protection device and a control method thereof. The elevator anti-shear protection device comprises a c-shaped stop dog (3), a spiral arm barrier unit (4), a base a(6), an elevator cab door upper top baffle 8b1, a spiral arm unit (9), a pressure braking device (10), a slide block (11), a supporting frame unit (12), a mortise lock unit (15), a mortise lock circuit unit (16), a blocking unit (17), an elevator using the elevator anti-shear protection device, an elevator master controller and a control method of the anti-shear protection device. When the elevator provided with the anti-shear protection device runs between flat beds, the elevator cab door cannot be opened by accident, passengers cannot step out from the elevator cab door of the elevator and enter gaps of the elevator cab door and an elevator shaft to produce a shear accident; and the ineffectiveness of a friction brake of the elevator and the drop of the elevator caused by the rope breakage of the elevator can be completely solved in the time period when the elevator is parked at the flat bed and the passengers come in and get out from the elevator, and the shear accident of the passenger caused by accidental ascending of the elevator can be solved.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator anti-shear protection device and a control method thereof. Background technique [0002] As more and more high-rise buildings are built, the elevator has become a necessary means of transportation for people to travel; currently, the elevator keeps stopping at a certain position, relying on the friction braking of the traction machine brake, elevator safety gear and other equipment to stop the car Movement; the failure of the above-mentioned friction brake occasionally occurs. If the accident occurs when passengers enter and exit the elevator on the leveling floor of the elevator, the consequences will be unimaginable; the failure of the current elevator door opening and closing control system also occurs. The door of the car is accidentally opened, and the passenger accidentally steps into the gap between the door of the elevator car and the elevator shaft in opera...

Problems solved by technology

[0002] As more and more high-rise buildings are built, the elevator has become a necessary means of transportation for people to travel; currently, the elevator keeps stopping at a certain position, relying on the friction braking of the traction machine brake, elevator safety gear and other equipment to stop the car Movement; the failure of the above-mentioned friction brake occasionally occurs. If the accident occurs when passengers enter and exit the elevator on the leveling floor of the elevator, the consequences will be unimaginable; the failure of the current elevator door opening and closing control system also occurs. The door of the car is accidentally opened, and the passenger accidentally steps into the gap between the door of the elevator car and the elevator shaft in operation. The elevator is still running, and the lives of the passengers are in danger; Effectively protect the lives of passengers; today's news media have successively reported that the above-mentioned elevator safety accidents have recently occurred, all of which ended in casualties of passengers. The above-mentioned elevator safety accidents are always threatening the lives of passengers, and it is a problem that people are eager to solve as soon as possible
