制动器在起重机起升机构中,其工作状态的正常与否是起重机能否安全、可靠运行的决定性因素之一。文中对制动器在线监测的功能、不足点以及改进方案进行分析,介绍新型制动器在线监测模拟,给出了在线监测的制动力矩曲线。与广大起重机设计、制造、使用者进行探讨,以谋求制动器长期、稳定的运行状态,确保起重机安全。
Brake lifting mechanism in the crane, the working status of the crane is normal or not safe and reliable operation of one of the decisive factors. In this paper, the function, shortage and improvement scheme of on-line brake monitoring are analyzed. The new brake on-line monitoring simulation is introduced and the on-line monitoring braking torque curve is given. With the majority of cranes design, manufacture, users to explore in order to seek long-term, stable operation of the brake to ensure crane safety.
