摘　　要：针对超深矿井提升机研制的超高压煤矿矿井液压制动系统,尚存在提高制动响应方面难题,提出了一种新型电机械制动技术,实现了制动系统的高响应;采用电机械设计理论,基于“电机-传动机构-驻车机构-制动踏面”结构,完成了制动器中主要零件的结构设计以及参数设定,并通过模态分析验证了结构的合理性;开发了PLC控制系统,提升了制动机械化和自动化的程度。实验表明:制动间隙消除时间有效控制在0.3 s内,且短时间内可到达目标制动正压力33 kN,符合煤矿矿井提升机制动要求。In view of the difficulties in improving the braking response of the hydraulic braking system developed by the ultra-deep mine hoist, a new electro-mechanical braking technology is proposed to realize the high response of the braking system. Based on the electro-mechanical design theory and the structure of "motor-transmission mechanism-parking mechanism-brake tread", the structural design and parameter setting of the main parts of the brake are completed, and the rationality of the structure is verified by modal analysis. PLC control system is developed to improve the degree of braking mechanization and automation. The experiment shows that the braking clearance elimination time is effectively controlled within 0.3 s, and the target braking positive pressure can be reached within a short time of 33 kN, which meets the dynamic requirements of the lifting mechanism of coal mine.
