摘要
针对胶轮式钻机在井下转场搬迁出现紧急情况时需要制动的安全问题,分析制动系统的工作原理,采用冗余设计理念,从静液压闭式系统和机械式湿式制动器两方面着手,设计了一种全液压湿式制动系统,使制动系统能够满足井下恶劣工况的使用要求.同时针对驻车制动压力不稳定的问题,进行分析计算,优选蓄能器组,达到安全驻车的目的.试验结果表明:整个系统驻车力矩高,解除压力稳定,行车制动性能安全可靠,反应迅速,刹车距离小于 8 m,有效解决了钻机搬迁时的紧急制动的安全问题.
Abstract
In view of the safety problem that rubber-tyred drilling rig need emergency braking during relocation in underground coal mines,the working principle of the brake system is analyzed,and the redundant design concept is adopted,a full hydraulic wet brake system is designed from the aspects of hydrostatic closed brake system and mechanical wet brake,which makes the brake system meet the requirement of the harsh working condition underground.At the same time,aiming at the problem of the instability of the parking brake pressure,the analysis and calculation are carried out,and the accumulator group is optimized to achieve the goal of safe parking.The test results show that the whole system has the advantages of high parking torque,stable release pressure,safe and reliable braking performance,quick response,and braking distance less than 8 m,which effectively solves the safety problem of emergency braking in the rig relocation.
