Emergent stopping device of car

Abstract

The invention provides an emergent stopping device of a car. The device comprises a plurality of braking mechanisms, a car, running guide rails, car doors and a control mechanism, wherein each braking mechanism comprises two braking boxes, a rolling shaft and a roller; the car is movably mounted on the running guide rail through the rollers; the a first mounting chamber and a second mounting chamber are arranged in each braking box; a braking block, a first electromagnetic absorbing component, a first electromagnetic absorbing body, a second electromagnetic absorbing body and a second electromagnetic absorbing component are mounted on each braking box; a buckling component is mounted on each second electromagnetic absorbing component; a buckling hole fitting the corresponding buckling component is formed in each braking box; a plurality of engaging holes are formed in the running guide rails; the cars are movably mounted on the car; a driving device, which is in drive connection with the car doors and can drive the car doors to move, is mounted on the car; the control mechanism comprises a control device and a rotating speed sensor. With the adoption of the device, people in the car can be effectively protected in case of car falling, and moreover, the car can be prevented from secondary falling after stopping falling.

Description

technical field [0001] The invention relates to the technical field of elevator safety, in particular to a car emergency stop 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 years, most ...
