Problems solved by technology

[0002] If an accident occurs during the operation of the vertical elevator (such as the wire rope slips or breaks, etc.), the elevator car will fall at the speed of free fall, which will pose a threat to the safety of the passengers
Existing elevator technology has taken measures to prevent accidents, but accidents still occur in real life. The present invention provides a protection device for vertical lift elevators when they fall accidentally.

Embodiment Construction

[0018] For the safety device of the vertical lift elevator, one 4-speed measuring device and one 7-controller are installed in the 2-elevator car; 4 pieces of 5-steel plates are evenly distributed on the elevator shaft wall, and the 5-steel plate and the 5-steel plate are supported by the 6-steel plate. 1- The elevator shaft wall is fixed; 4 3-electromagnets are installed on the upper part of the 2-elevator car corresponding to the 5-steel plate; one 8-emergency button is installed on the control panel in the 2-elevator car.

[0019] The device operates as follows:

[0020] (1) Automatic control scheme

[0021] Such as figure 1 , figure 2 As shown, when the 4-speed measuring device senses that the downward speed of the 2-elevator car exceeds the design speed (when a fall accident occurs), the 4-speed measuring device sends a signal to the 7-controller, and the 7-controller activates the 3-electromagnet , the 3-electromagnet absorbs the 5-steel plate, and generates frictio...

Abstract

The invention provides a safety device of a vertical elevator; one 4- speed measuring device and one 7- controller are installed on a 2- elevator car; four 5- steel plates are uniformly distributed onan elevator shaft wall; the 5- steel plates and the 1- elevator shaft wall are fixed together by 6- steel plate support; four 3- electromagnets are installed at the position where the upper part of 2- elevator car corresponds to 5- steel plates; and one 8- emergency button is arranged on a control panel in the 2- elevator car. By using the adsorption force of the electromagnet, the falling forceof the elevator is delivered to the wall of the elevator shaft, so that the purposes of deceleration and parking are achieved. When accidentally falling, the elevator can slow down and stop.

Description

technical field [0001] The invention is used to prevent personal casualties and property loss accidents caused by the accidental fall of the vertical lift elevator. Background technique [0002] If an accident occurs during the operation of the vertical elevator (such as the wire rope slips or breaks, etc.), the elevator car will fall at the speed of free fall, which will pose a threat to the safety of the passengers. Existing elevator technology has taken measures to prevent accidents, but accidents still occur in real life. The present invention provides a protection device for vertical lift elevators when they fall accidentally. Contents of the invention [0003] The object of the present invention is to provide a safety device for a vertical lift elevator, which can slow down and stop the elevator when it falls accidentally, so as to prevent casualties and property damage accidents caused by the accidental fall of the elevator. [0004] Technical scheme of the present...
