Abstract

The invention relates to the technical field of elevators, discloses a safety protection device for an elevator, and solves the current problem that the safety protection measures for the elevator sliding down or rolling down are single and the elevator cannot be effectively prevented from sliding down or rolling down. The device comprises an elevator shaft, wherein both ends of the two side wallsof the elevator shaft are provided with first moving grooves, both sides of the middle of the two side walls of the elevator shaft are symmetrically provided with friction grooves, blocking grooves are provided in the middle of both side walls of the elevator shaft, blocking mechanisms are installed in the middle of the two blocking grooves, three second moving grooves are provided at equal distances on the rear side wall of the elevator shaft, an elevator car is installed inside the elevator shaft, and a moving control mechanism is installed on the top of the elevator car. The elevator has various safety protection measures to prevent sliding down and rolling down, so as to ensure the safety of passengers when the elevator is sliding down or rolling down. At the same time, the safety protection measures of the elevator can effectively prevent the elevator from sliding down or rolling down after starting, so as to increase the safety performance of the elevator.

Description

technical field [0001] The invention belongs to the technical field of elevators, in particular to an elevator safety protection device. Background technique [0002] Elevator (vertical elevator) is a kind of transportation equipment that transports pedestrians or goods vertically; the elevator serves buildings on specified floors, and the vertical elevator has a car that runs between at least two columns of rigid guide rails with vertical or inclined angles less than 15 degrees. It is convenient for passengers to enter and exit or load and unload goods. According to the speed, it can be divided into low-speed elevators (less than 4 meters per second), fast elevators (4 to 12 meters per second) and high-speed elevators (above 12 meters per second). [0003] Although the current elevator safety design is becoming more and more perfect, the elevator sometimes has the problem of sliding or sliding due to various faults; for the elevator sliding and sliding, the existing elevato...
