Embodiment 1

[0023] Such as figure 1 A kind of safety elevator shown comprises car 3, hoistway 7, anti-falling device and controller, and described car 3 is positioned in hoistway 7, and the top of described car 3 is connected with rope 1; The falling device is fixedly arranged in the grooves on both sides of the car 3; the falling preventing device includes a cylinder 4, a deceleration plate 5, a friction layer 2, an upper magnetic plate 9 and a lower magnetic plate 11, and the deceleration plate 5 is fixedly arranged on The piston rod extension end of the cylinder 4, the friction layer 2 is arranged on the inner wall of the lifting passage 7, the speed reduction plate 5 is fixedly arranged on the piston rod extension end of the cylinder 4, and the speed reduction plate 5 is parallel to the friction layer 2 Setting, the cylinder 4 is electrically connected to the controller, and the cylinder 4 receives the command signal sent by the controller and executes the action; the upper magnetic p...

Embodiment 2

[0030] This embodiment makes some improvements to Embodiment 1. A buffer layer 12 is provided at the bottom of the lifting passage 7, and the buffer layer 12 is located at the bottom of the lower magnetic plate 11. After the deceleration of the frictional force of the upper magnetic plate 9 and the lower magnetic plate 11, the car 3 has not stopped moving and can be further decelerated through the buffer layer 12; a communication device is provided in the car 3 to facilitate failure In the car 3, an oxygen supply device is arranged to prevent anoxic condition in the car when an unexpected situation occurs.

Abstract

The invention provides a safe elevator which comprises a car, a lifting passage, an anti-falling device and a controller, wherein the anti-falling device comprises air cylinders fixed in grooves on two side surfaces of the car, speed brakes fixed at the extending ends of piston rods of the air cylinders, friction layers arranged on the inner walls of the lifting passage, and an upper magnetic plate and a lower magnetic plate which are fixed at the top end and the bottom end of the car respectively; and the air cylinders are electrically connected with the controller. The safe elevator provided by the invention comprises friction deceleration, magnetic deceleration and buffering deceleration, and adopts a corresponding deceleration measure according to the speed and height of the car when the car goes wrong, so that the safety performance of the elevator is greatly improved.

Description

technical field [0001] The invention belongs to the field of elevators, in particular to a safety elevator. 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. As a means of transportation in high-rise buildings, elevators have brought great convenience to people's lives, but at the same time, taking elevators also contains great risks. Elevators fall every year, causing casualties; most elevators currently use mechanical anti-fall protection devices, but the safety factor of mechanical protection devices is low and requires frequent manual maintenance, which not only brings trouble to use, but also causes Waste of resources. Contents of the invention [0003] In view of this, the present invention aims to propose a safety elevator to improve the safety factor of the elevator and ensure the safety of the passengers. [00...
