矿井提升正向着大吨位、高速度和自动化方向发展。如竖井提升容器有效载重已达80吨,提升速度已达20米/秒。所以,正确分析罐道与罐耳在提升过程中的作用力,改进其结构和安装水平也是有重要意义的。 目前使用的罐道有木罐道、钢绳罐道和钢罐道。木罐道有其明显的优缺点,但使用条件有限;钢绳罐道在井筒深度二千米以上就难以使用。钢罐道能适应大吨位、高速度的需要,但制造、安装技术水平要求高。近年来开始采用型钢组合罐道,同时,在提升容器上安装橡胶滚轮罐耳。不久前,加拿大又提出圆环形断面的钢罐道。
Mine upgrading is toward large tonnage, high speed and automation direction. As shaft hoist container effective load has reached 80 tons, lifting speed has reached 20 meters / second. Therefore, it is of great significance to correctly analyze the forces acting on cans and cans during the lifting process to improve their structure and installation level. The current use of the cans are wooden cans, steel cans and steel cans Road Road. Mutianyu has its obvious advantages and disadvantages, but the conditions of use are limited; it can be difficult to use it in the well depth of more than two thousand meters. Steel cans to adapt to large tonnage, high-speed needs, but manufacturing, installation of high technical requirements. In recent years, the use of steel composite cans began, at the same time, to enhance the container to install rubber roller cans. Not long ago, Canada also proposed a circular section of the steel can road.
