Research and Implementation of a Novel Elevator Speed Limiter Test Device

Abstract

According to the requirements of GB/T 7588.1—2020^[1],the operating speed and tensile force of the elevator speed limiter need to be measured.Under the actual operating conditions,the operating speed and tensile force of the speed limiter are generated simultaneously,and the process is generally completed within 2 seconds.The traditional test method is to measure these two parameters separately,which is time-consuming and inefficient.In particular,it cannot fully reflect the force condition of the speed limiter rope under the actual operation condition.Aiming at above problems,in this paper,a new type of elevator speed limiter test device is designed.By constructing a torque dynamic compensation model,the action process of the speed limiter is amplified and the torque compensation is carried out,which accurately reproduces the real working conditions and greatly improves the test efficiency and reliability of the results.
