Background

An elevator is a permanent transport device serving a number of specific floors in a building, the cars of which travel in at least two rigid tracks perpendicular to the horizontal or inclined at an angle of less than 15 ° to the vertical. There are also steps, where the tread plates are mounted on a track for continuous operation, commonly known as escalators or moving walkways. A fixed elevator apparatus serving a predetermined floor. The vertical lift elevator has a car that runs between at least two vertical rows of rigid guide rails or guide rails with an angle of inclination of less than 15 °. The size and the structural form of the car are convenient for passengers to access or load and unload goods. It is customary to use elevators as a generic term for vertical transport means in buildings, irrespective of their drive mode. The elevator can be divided into a low-speed elevator (below 4 m/s), a fast elevator (4-12 m/s) and a high-speed elevator (above 12 m/s) according to the speed, two ends of a traction rope are respectively connected with a lift car and a counterweight and wound on a traction sheave and a guide pulley, a traction motor drives the traction sheave to rotate after changing the speed through a speed reducer, and the lift car and the counterweight can move up and down by virtue of the traction force generated by friction between the traction rope and the traction sheave, so that the purpose of transportation is achieved.

The existing car anti-falling device generally realizes the anti-falling of an elevator by limiting the sliding of the car anti-falling device on a rail, for example, the elevator anti-falling device with the publication number of CN206437736U realizes the emergency stop of the elevator through a backstop, a buffer hydraulic press and a guide wheel, but because the elevator falling process is short, the situation that the elevator falls to the ground and the backstop and the hydraulic press do not work is easy to occur, so that the casualties of people in the elevator are easy to cause, and therefore, a vertical lift elevator anti-falling mechanism is provided to solve the problems.
