铸焊中部槽使用寿命短原因分析
|
摘要
重型刮板输送机是现代综采工作面最主要的运输设备,中部槽做为铸焊刮板输送机最关键部件的之一,其使用寿命一直是研究的重点。中部槽是由高强度耐磨钢板与铸造槽帮拼接而成的,具有结构简单、焊接方便等优点,被得到了广泛应用。由于各煤矿的采掘工作面地质条件的差异性,影响刮板输送机整体使用寿命,尤以影响对中部槽使用寿命最为突出,着重从中部槽中板上做出小的改进来提高中部槽的使用寿命。
Heavy scraper conveyor is the most important transportation equipment in modern comprehensive mining face.The central groove is one of the most important parts of the casting and welding scraper conveyor.Its service life has always been the focus of research.The central groove is made up of high-strength wear-resistant steel plates and casting troughs.It has simple structure and easy welding,and other advantages.It has been widely used.Due to the difference of the geological conditions of the mining face of each coal mine,the whole life of the scraper conveyor is affected,especially the life of the central trough is most prominent.Focuse on making small improvements from the central trough plate to improve the service life of the central trough.
