An elevator fall protection device

Abstract

The invention discloses an elevator fall protection device, which comprises a storage battery, slide rails, a generator, a car and a pulley. The outside of the car is provided with slide rails. Welded with fixed rod. In the present invention, the first gear meshed with the second gear is fixed at one end of the first rotating shaft, and the first brake pad and the second brake pad matched with the pulley and the second rotating shaft are respectively fixed at the output end of the electric telescopic rod. and the second gear is connected to the input end of the generator through a pulley mechanism, not only the second rotating shaft can be used to drive the generator to generate electricity, but also the first brake pad and the second brake pad can be used to brake at the same time , increase the braking area, improve the braking effect, generate electricity during the movement of the car, use a separate power supply for power supply during the fall, improve the stability of protection, and improve the effect of fall protection.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator fall protection device. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails perpendicular to the horizontal plane or with an inclination angle of less than 15° from the plumb line. Running continuously on the crawler belt, commonly known as escalators or moving walks, serving fixed lifting equipment for specified floors, vertical lifts have a car that runs between at least two vertical or rigid guide rails with an inclination angle of less than 15°, The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use the elevator as a general term for the vertical transportation in the building regardless of its driving mode. During the use of the elevator, the elevator ...
