Wind resistance induction type elevator safety braking controller

Abstract

The invention discloses a wind resistance induction type elevator safety braking controller. The wind resistance induction type elevator safety braking controller comprises a shell fixedly connected with an elevator car. A guide rail guide groove matched with a guide rail is formed in the shell. The shell is further connected with a displacement induction mechanism. A linkage mechanism matched with the displacement induction mechanism is installed on the shell. The shell is further matched with braking slide blocks in a sliding manner, wherein the braking slide blocks are connected with the linkage mechanism and are used for braking. The displacement induction mechanism is used for inducing the operation speed of an elevator and is connected with the linkage mechanism. A pair of braking guide grooves which are perpendicular to the guide rail guide groove and communicate with the guide rail guide groove are formed in the shell. The braking guide grooves are symmetrically distributed inthe two ends of the guide rail guide groove and are matched with the braking slide blocks. The braking guide grooves are used for guiding the braking slide blocks to make the braking slide blocks slide in the direction perpendicular to the guide rail guide groove.

Description

[0001] This invention is a divisional application of the invention patent with the application date of February 05, 2017, the application number: 2017100647301, and the invention title of "wind resistance sensing device based on aerodynamics". technical field [0002] The invention relates to a wind resistance sensing device. Background technique [0003] At present, known elevator fall arresters are mainly triggered in two ways. One is to use weightlessness to sense, and when the elevator slides rapidly, the counterweight is in a state of weightlessness to trigger; Sensing, such as velocity sensing. [0004] The invention provides an elevator fall arrester triggered by wind resistance, which is different from the trigger principle of the existing fall arrester. Contents of the invention [0005] The purpose of the present invention is to provide a windage induction type fall arrester which is different from the triggering principle of the existing fall arrester. When the...

[0005] The purpose of the present invention is to provide a windage induction type fall arrester which is different from the triggering principle of the existing fall arrester. When the elevator slides down rapidly, a large windage is generated and the work of the windage trigger mechanism is used. The windage induction type fall arrester can solve the problem of weightlessness The one-way problem of induction, and can solve the stability problem of electronic induction equipment
