为了增强煤矿立井提升容器的稳定性,常采用四角罐道的结构形式来代替端罐道中断部位。目前四角罐道的设计参照端罐道方法,但由于四角罐道与端罐道的结构形式和约束条件存在较大差异,参照端罐道设计方法计算得到的四角罐道作用力是否可靠存在疑问。为了解决这一问题,本文通过对四角罐道作用力的现场测试,得到了四角罐道在加卸载工况中的加速度时程曲线。通过分析时程曲线,确定了四角罐道的作用力,并探明了其特征及影响因素。进一步进行回归分析后,考虑到提升终端荷载水平,建立了煤矿立井四角罐道水平力及竖向力的计算方法。基于现场测试结果建立的四角罐道作用力计算方法具有可靠性,对于提升四角罐道的稳定性、安全性以及经济性具有参考意义。
In order to enhance the stability of the coal mine shaft lifting vessel, the structural form of four-corner guide rails is often used to replace the interrupted part of the end tank passage. However, the current design method of four-corner guide rails is based on the design method of the end tank passage. However, due to the great differences in the structural forms and constraints between four-corner guide rails and the end tank passage, the reliability of the force of four-corner guide rails calculated by referring to the design method of the end tank passage is doubtful. In order to solve this problem, the acceleration time history curve of the four-corner guide rails under loading and unloading conditions is obtained through the field test of the force of the four-corner guide rails. By analyzing the time-history curve, the force of the four-corner guide rails is determined, and its characteristics and influencing factors are proved. After further regression analysis, the calculation method of horizontal force and vertical force of four-corner guide rails of coal mine shaft is established considering the lifting terminal load level. The calculation method based on the field test results is reliable and has important significance for improving the stability, safety and economy of the four-corner guide rails.
