摘要
针对大圆形轨双桥架式起重机旋转半径大、室外作业、桅柱及旋转传动装置受多种力作用等特点,介绍一种特种起重机的结构设计。通过采用新的结构,并对其进行力学分析和反复试验,该机桥架最大振幅约2.1 cm,振动较小,摆动幅度低,整机工作平稳,安全可靠。
Considering the characteristics of double-bridge cranes along large round track such as the big rotation radius,outdoor operation,and mast and rotary mechanism affected by many kinds of forces,this paper introduces structural design of the special crane.Mechanics analysis and repeated tests show that the vibration of the special crane with new structure is small with the maximum amplitude of about 2.1 centimeter,and the whole crane features stable,safe and reliable performance.
