Abstract

The invention relates to the technical field of elevators, and discloses a safety protection device for an elevator, which solves the problem that the current safety protection measures for the elevator sliding or sliding car are single and cannot effectively prevent the elevator sliding or sliding car. , both ends of the two sides of the elevator shaft are provided with first moving grooves, both sides of the middle of the two sides of the elevator shaft are symmetrically provided with friction grooves, and the middle of the two sides of the elevator shaft are provided with blocking grooves. A blocking mechanism is installed in the middle of the blocking trough, and three second moving troughs are arranged equidistantly on the rear side wall of the elevator shaft. An elevator car is installed inside the elevator shaft, and a mobile control mechanism is installed on the top of the elevator car; the elevator has multiple A safety protection measure to prevent the elevator from slipping and slipping, so that the life safety of passengers can be guaranteed when the elevator slips or slips. 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...
