Novel elevator falling protection device

Abstract

The invention provides a novel elevator falling protection device. The device comprises a plurality of first braking mechanisms, running guide rails, a second braking mechanism and a control mechanism, wherein each first braking mechanism comprises two braking boxes, a rotating shaft and a running wheel; a separating plate, a moving block, a braking block, a forward-pushing block and a plurality of blocking blocks are mounted in each braking box; a mounting chamber is formed in each braking box; each mounting chamber is divided into a first chamber body and a second chamber body through the separating plates in the direction vertical to the axial direction of the corresponding rotating shaft; each second chamber body is positioned at one side, far away from the corresponding running wheel, of the corresponding separating plate; the car is movably mounted on the running guide rails through the running wheels; the running guide rails are provided with hanging plates at positions corresponding to a landing door of an elevator; the second braking mechanism comprises a plurality of speed reduction hanging hooks and a driving device; the control mechanism comprises a control device, a light receiver, a plurality of light emitters and a rotating speed sensor. With the adoption of the device, people in a car can be effectively protected in case of fast falling of the car, and the car can be stopped at a position in which the rescuing can be carried out conveniently.

Description

technical field [0001] The invention relates to the technical field of elevator safety, in particular to a novel elevator fall protection device. 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 recent ...

AI Technical Summary

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.
