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.

Description

technical field [0001] The invention relates to a safety device of a vertical elevator, belonging to the technical field of elevator safety devices. Background technique [0002] From time to time, there are reports of elevators falling and hurting people in the media. More and more high-rise buildings are built, and elevators are an indispensable means of transportation every day. For high-rise building operators, special attention should be paid to the quality of elevators and the status of annual inspections of elevators. Although elevator accidents are very rare, once an accident occurs, human life is at stake, and even minor ones may cause physical disability. Most of the safety devices of existing vertical lift elevators are installed on the outside of the elevator, such as the bottom of the elevator box or the side wall of the elevator box. For the personnel standing inside the elevator, various safety devices cannot be seen or touched. I don't know, I don't know wh...
