Safety device for vertical elevator

Abstract

The invention provides a safety device for a vertical elevator and belongs to the technical field of safety devices for elevators. A lower safety device comprises two pulley blocks, damping springs, a pedal, a ratchet wheel, a rope wheel, a handle, a jack, a jack shaft, a spring piece, a rocker handle, an upper safety device comprises a plurality of elastic lifting devices, and each elastic lifting device comprises two boxes, shafts, a rubber sleeve, two box connecting seats and steel sheet springs. The upper safety device can be used simultaneously with the lower safety device; when the damping springs quickly release elasticity to enable the pedal to rise, a passenger in the elevator quickly grasps the rubber sleeve and tries hard to hang the body up to reduce inertia when the elevator falls down. After the safety device is mounted, the passenger in the elevator can see and touch; the safety device is an ornament just like a life jacket in a cabin at ordinary times, and once the elevator falls down, probability of disabling can be greatly lowered; the safety device is used for protecting life safety of the passenger in the elevator.
