Traction driving passenger elevator with power failure protection function

Abstract

The invention discloses a traction driving passenger elevator with a power failure protection function. The traction driving passenger elevator comprises an elevator car, wherein an elevator cavity is formed in the elevator car; an elevator is arranged in the elevator cavity in a sliding manner; a top plate is fixedly arranged at the upper side of the elevator; a traction machine is fixedly arranged on the top surface of the top plate; a traction cavity is formed in the front side surface of the traction machine; a main shaft is rotationally arranged on the rear wall of the traction cavity; a traction wheel is fixedly arranged on the periphery of the main shaft; a traction rope is fixedly arranged on the top surface of the elevator; a support plate is fixedly arranged on the rear wall of the elevator cavity; a positioner is fixedly arranged on the left side surface of the support plate; two brake cranked levers which are in bilateral symmetry are rotationally arranged in the traction cavity; a first clamping block is fixedly arranged on the top surface of the elevator; a fixing plate is fixedly arranged on the rear wall of the elevator cavity; and a second clamping block is arranged on the top surface of the elevator in a sliding manner. According to the traction driving passenger elevator, emergency braking can be conducted on the elevator during a power failure, so that the elevator is prevented from falling, the elevator can be rapidly positioned and supported, and the elevator is prevented from continuously falling, so as to ensure that passengers safely leave the elevator.

Description

technical field [0001] The invention relates to the technical field of elevator power failure protection, in particular to a traction-driven passenger elevator with power failure protection function. Background technique [0002] Elevators are necessary transportation equipment for high-rise buildings. When a power failure occurs, the elevator will fail to operate. If braking measures are not taken in time, the elevator may fall, which cannot guarantee the safety of passengers in the elevator. When the elevator breaks down, it may cause the elevator to slide at an overspeed, causing injury or even death to the passengers in the elevator; [0003] Moreover, when the elevator is fixed at a higher position, if the passengers in the elevator are evacuated, the elevator will definitely vibrate, which will lead to the risk of the elevator falling twice. Larger vibrations may cause discomfort or injury to passengers. Contents of the invention [0004] The object of the present ...
