Abstract

The invention discloses an elevator speed measuring device. The operating speed and the operating direction of an elevator can be reflected by the rotating speed and the rotating direction of a lift car sheave, multiple induction blocks can rotate along with the rotation of the lift car sheave while the lift car sheave rotates, pulse signals for reflecting the rotation of the induction blocks can be sensed by a first speed measuring probe and a second speed measuring probe, the pulse signals can be transmitted to an elevator main control panel, the actual operation speed and the actual operating direction of the elevator can be obtained due to the calculation of the elevator main control panel, the monitoring for the excessive speed and the reversion of the elevator and the fault of a coder can be realized, the operation safety of the elevator can be increased, and the elevator accident can be prevented from happening.

Description

[0001] technical field [0002] The invention relates to an elevator speed measuring device. [0003] Background technique [0004] In the prior art, the elevator uses an encoder to measure the actual running speed. Since there is no comparison and reference, the elevator running speed obtained only through the encoder cannot be identified accurately, which may cause safety accidents. [0005] Contents of the invention [0006] The purpose of the present invention is to provide an elevator speed measuring device, which can obtain the actual running speed value and running direction of the elevator through the pulse signal obtained by the first speed measuring probe and the second speed measuring probe inductive block, so as to realize the accurate monitoring of the overspeed and reverse of the elevator , It can also be compared with the measured value of the encoder to feedback whether the encoder is wrong, increasing the safety of elevator operation. [0007] In order ...
