The invention relates to a double-flat-arm derrick torque monitoring device which comprises a rod body, suspension arms are symmetrically arranged on the left side and the right side of the rod body, a tackle is arranged on the suspension arms in a sliding mode, a crane scale, a laser range finder, a controller, a circular grating encoder and an NFC position recognizer are arranged on the tackle, and a gear on the circular grating encoder is matched with a rack on the suspension arm. The controller is in electric control connection with the laser range finder, the circular grating encoder and the NFC position recognizer, NFC position labels spaced by a first distance are arranged on the suspension arm, and the NFC position labels are located in the induction range of the NFC position recognizer. Compared with the prior art, the method has the advantages of real-time unbalanced torque difference display, over-limit alarm and the like.

    本发明涉及一种双平臂抱杆力矩监测装置,装置包括杆体,杆体左右两侧对称设置有吊臂,吊臂上滑动设置有滑车,滑车上设有吊秤、激光测距仪、控制器、圆光栅编码器和NFC位置识别器,圆光栅编码器上的齿轮与吊臂上的齿条匹配,控制器分别与激光测距仪、圆光栅编码器和NFC位置识别器电控连接,吊臂上设有相隔第一间距的NFC位置标签,NFC位置标签位于NFC位置识别器的感应范围内。与现有技术相比,本发明具有实时不平衡力矩差显示及超限告警等优点。
