Publication number: 20220388810Abstract: An elevator health state online monitoring method includes: acquiring parameters such as a position, a three-axis acceleration, an inclination angle, and a noise of a car in a running state of an elevator, left and right brake temperatures of a traction machine, and an environment temperature. Parameter measuring devices are installed on a top of the car and at the brake side of the traction machine. The parameters are collected to a cloud database through a wireless network after being acquired, and a judgment result is given through background automatic analysis. The method is mainly used for monitoring whether key mechanical parts of the elevator are abnormal or not, including guide rail deformation, guide shoe abrasion, car sliding, brake abrasion, adhesion, and the like. This way the health state of the elevator can be automatically monitored, and early warning can be carried out in time when abnormity is found.Type: ApplicationFiled: April 11, 2022Publication date: December 8, 2022Applicant: CHANGSHU INSTITUTE OF TECHNOLOGYInventors: Yang GE, Benlian XU, Jiancong QIN, Lingyun MA, Jianxin DING, Fusheng ZHANG, Jiaxin MA, Yong REN, Laipeng YAO

Patent number: 10399822Abstract: A hydraulic elevating platform having no guide rails and an elevating method. A hydraulic power pack drives three parallel hydraulic cylinders to work synchronously, thereby implementing the rising and falling of an elevating platform; when the elevating platform reaches a predetermined floor, an upper electric pushrod pushes a pedal assembly out, and then the pedal assembly drives a pedal to rise by means of a pedal elevating system until the pedal is flush with the surface of a loading table of the elevating platform; outward-swinging doors between the elevating platform and a floor open to form pedal guardrails; then sliding doors open and a man can step onto a stair via the pedal assembly. An eccentric loading adjusting means eliminates eccentric loading to achieve balance about the center of gravity, thereby eliminating the eccentric loading of the platform. The elevating platform is simple in structure, safe, reliable, and easy to maintain.Type: GrantFiled: December 29, 2015Date of Patent: September 3, 2019Assignee: Dongnan Elevator Co., Ltd.Inventors: Zhencai Zhu, Guohua Cao, Jiancong Qin, Panda Wang, Weihong Peng, Lingyun Ma, Yiping Ma, Ming Gao, Jianrong Yang, Lei Wei
