随着煤炭工业的迅速发展,矿井运量日益增大,大倾角、长距离的带式输送机越来越普及。普通天倾角输送机上运角度为18°～28°,下运倾角为16°～25°。而有些矿井为了减少巷道开拓量和设备投资,并加快工程进度,又将巷道倾角加大,甚至超出了普通大倾角输送机设计所能达到的最大角度。为了满足这些矿井的需要,提高大倾角输送机设计水平势在必行。该文以河南众信机械制造有限公司为某煤业有限公司设计制造的主井32°大倾角带式输送机为例
With the rapid development of the coal industry, the volume of mine shafts has been increasing day by day. Belt conveyors with large inclination and long distance have become more and more popular. Ordinary day angle conveyor conveyor angle of 18 ° ~ 28 °, the lower transport angle of 16 ° ~ 25 °. In order to reduce the amount of roadway development and equipment investment and speed up the construction progress, some mines will further increase the inclination angle of the roadway even beyond the maximum angle that can be achieved by the design of ordinary large-angle conveyor. In order to meet the needs of these mines, it is imperative to improve the design of large-angle conveyors. In this paper, Henan Zhongxin Machinery Manufacturing Co., Ltd. is a 32 ° inclined angle belt conveyor designed and manufactured by a coal company as an example
