AI Technical Summary
Existing methods for detecting elevator slip are inefficient and inaccurate, and traditional contact measuring devices are easily damaged and complex to install, making it difficult to meet the requirements for high-precision detection.
A non-contact speed measuring instrument and a rotation angle measuring device are used to calculate the slippage of the rope sheave by measuring the instantaneous speed of the traction rope and the total rotation angle of the traction sheave. The device is externally installed to avoid wear.
It improves the accuracy and precision of measurements, facilitates the layout and installation of the device, reduces maintenance costs, and adapts to the testing needs of different types of traction sheaves.
