一、设计方案在TQ—16型塔式起重机上安装一套单参数矩力限制器(图1),只要臂杆的顶尖安装一个悬臂梁式传感器与提升钢丝绳的死端相连接,利用应变式悬臂梁式传感器检测提升钢丝绳的张力,就能检测出起重机的力矩。如果起重机的工作力矩达到了额定力矩的90％,传感器输出一个信号给显示仪表,在显示仪表表头显示出实际力矩数,同时给预警讯响器输入信号使讯响器发出灯光和声响预警讯号,提醒操作人员注意。当工作力矩达到额定力矩的105％时,传感器继续给显示仪表和讯响器输入信号,使它们显示
First, the design of the TQ-16 tower crane mounted on a single parameter torque limiter (Figure 1), as long as the top of the boom to install a cantilever sensor and the dead end of the hoisting rope is connected, the use of strain-type The cantilever sensor detects the tension of the hoisting ropes to detect the crane’s torque. If the working torque of the crane reaches 90% of the rated torque, the sensor outputs a signal to the display meter, which shows the actual torque number on the display meter meter. At the same time, the pre-alarm signal is input to make the alarm emit light and sound early warning signal to remind Operator attention. When the working torque reaches 105% of the rated torque, the sensor continues to input signals to the display meter and sounder so that they display
