Patent number: 11305946Abstract: The present invention discloses a drive system of a scraper conveyor and a control method. The drive system includes a nose sprocket, a tail sprocket, a nose sprocket drive mechanism, and a tail sprocket drive mechanism, where the nose sprocket drive mechanism is a hydraulic motor I, and the tail sprocket drive mechanism is a hydraulic motor II; and a hydraulic system that drives the hydraulic motor I and a hydraulic system that drives the hydraulic motor II include same hydraulic elements, and both include a three-position four-way solenoid directional valve, a two-position two-way solenoid directional valve, a two-position three-way solenoid directional valve, an accumulator, and an oil supplement valve group. The present invention is applicable to rapid starting and stopping of the scraper conveyor in a heavy load status while adjusting chain tension in real time, thereby resolving a power imbalance problem in a dual-drive system, and has a simple structure and a long service life.Type: GrantFiled: April 10, 2020Date of Patent: April 19, 2022Assignees: China University of Mining and Technology, JIANGSU TIANMING MACHINERY GROUP CO., LTD.Inventors: Gang Shen, Zhencai Zhu, Kaiyu Dai, Yu Tang, Xiang Li, Yuxing Peng, Hao Lu, Guohua Cao, Gongbo Zhou, Wei Li, Fan Jiang

Patent number: 10819128Abstract: A device for enabling autonomous powering of a monitoring node of a scraper conveyor chain includes a bottom baffle, a friction wheel drive device, a limiting device, a generator, an energy storage battery, a cable entry device, and dampers. The bottom baffle is connected to a bottom portion of a scraper of a scraper conveyor. The friction wheel drive device comprises a ball, a friction wheel, a drive shaft connected to the generator, and a shaft coupler. The friction wheel is disposed on the drive shaft, and an outer edge of the friction wheel is in contact with a surface of the ball. The limiting device is a ball housing that is connected to the bottom baffle, and is used for limiting the ball within the ball housing. The energy storage battery is connected to the generator, and is used to store electrical energy generated from the generator. The dampers are disposed on the drive shaft.Type: GrantFiled: November 26, 2018Date of Patent: October 27, 2020Assignees: China University of Mining and Technology, JIANGSU TIANMING MACHINERY GROUPInventors: Gongbo Zhou, Zhencai Zhu, Yaobin Lv, Benliang Hao, Wei Li, Pengpeng Chen, Guohua Cao, Junhua Yi, Yuxing Peng, Gang Shen
