力矩限制器是履带式起重机中非常重要的安全监控装置,能对起重设备的作业进行实时监控和记录,自动实现过载保护和过仰保护,确保起重机在安全范围内作业,在危险工况或者过载时进行报警,同时切断危险方向的动作,以保证起重设备及人员的安全。说明力矩限制器的主要工作原理,并以履带式起重机的塔臂超起工况为计算工况,进行结构分析,介绍由载荷信息计算实际载荷的方法。对力矩限制器在实际使用中存在的因角度不准而造成工作幅度计算不准确、显示的载荷读数与实际载荷不符,以及同一个载荷变幅向上和变幅向下时显示载荷不同等问题进行分析并提出解决办法。
Torque limiter is a very important safety monitoring device in crawler cranes. It can monitor and record the operation of lifting equipment in real time, automatically realize overload protection and oversoft protection, ensure the crane can work safely. In dangerous working condition or Alarm when overload, at the same time cut off the dangerous direction of action, in order to ensure the safety of lifting equipment and personnel. The main working principle of the torque limiter is described. The structural analysis is carried out based on the overturning condition of the tower crane of the crawler crane, and the method of calculating the actual load from the load information is introduced. In the actual use of the torque limiter due to inaccurate angles caused by inaccurate calculation of the working range, the load readings displayed and the actual load does not match, and the same load amplitude up and down load display when the load is different Analyze and propose solutions.
