Escalator vibration reduction system and escalator vibration reduction method

Abstract

The invention relates to an escalator vibration reduction system and an escalator vibration reduction method. The escalator vibration reduction system comprises a guide rail, steps, a driving unit and a speed regulation unit. The two ends of the guide rail are provided with bearing supporting bases and driving shafts rotationally arranged on the bearing supporting bases; the plurality of steps are connected together through step chains to form a conveying chain ring, the conveying chain ring is wound on the two driving shafts along the guide rail, and guide wheels of the steps are in sliding fit with the guide rail; the driving unit is in transmission connection with the driving shafts, and vibration sensors are arranged on the driving unit, the guide rail and the two driving shafts; and the speed regulation unit is used for controlling the running speed of the driving unit, and each vibration sensor is electrically connected with the speed regulation unit. The vibration condition of all components is detected in real time, and the speed regulation unit regulates the running speed of the driving unit when the vibration of some components is abnormal, so that the resonance condition of an escalator is effectively avoided, the use safety is improved, and meanwhile, the service life is also prolonged.

Description

technical field [0001] The invention relates to the technical field of escalator devices, in particular to an escalator vibration reduction system and an escalator vibration reduction method. Background technique [0002] With the development of society, escalators or moving walks are widely used in various public places. When the escalator is running, the steps slide along the guide rail under the action of the drive unit, and passengers stand on the steps and move forward synchronously with the steps. Due to various reasons such as the use environment and manufacturing precision, there will be vibration during the operation of the escalator. Vibration will affect the comfort of passengers on the escalator, cause noise, and affect the service life of the escalator. In particular, when resonance occurs, there will be a great potential safety hazard. Contents of the invention [0003] Aiming at the problem that if the resonance occurs during the operation of the escalato...
