A device for decelerating elevators

Abstract

The invention provides a device for reducing the falling speed of an elevator. The device comprises guide rollers and speed reducers, wherein each speed reducer comprises a connecting shaft, a mounting housing, a pushing component, a plurality of first elastic components, a plurality of centrifuging components, a first balancing component, a compressing component and a second elastic component; each connecting shaft is mounted on the corresponding mounting housing and connected to the corresponding guide roller; each pushing component is movably mounted in the corresponding mounting housing; first ends, corresponding to the pushing components, of the first elastic components, are mounted on the connecting shafts and uniformly distributed at the outer sides of the connecting shafts; the centrifuging components are mounted at second ends of the first elastic components; each first balancing component is rotatably mounted in the corresponding mounting housing; the first end of each first balancing component is mounted at a position, corresponding to the corresponding guide roller, of the corresponding compressing component; the second end of each first balancing component is movably connected to the corresponding pushing component; one side, far away from the corresponding connecting shaft, of the second end of each first balancing component, is mounted on the corresponding mounting housing through the corresponding second elastic component. With the adoption of the device, the speed of the elevator which runs at an abnormal speed can be reduced, and the speed reducing effect is improved as the elevator runs more over the normal speed.

Description

technical field [0001] The invention relates to the technical field of elevator safety, in particular to a device for decelerating elevator falling. Background technique [0002] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, which is used for multi-storey buildings to take people or carry goods. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. A vertical elevator has a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. 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 elevator as a general term for vertical transportation in buildings regardless of its driving mode. For the elevator of vertical lift, there have been many accidents in rece...

Problems solved by technology

For elevators that lift vertically, there have been many accidents in recent years, most of which fell to the ground suddenly, causing heavy casualties and bringing great pain to people. There are not many safety protection methods for elevators.
