Anti-overloading type excavator weighing device
The invention relates to the technical field of excavator weighing, in particular to an anti-overloading type excavator weighing device which comprises a weighing device body, the weighing device body comprises a bearing part of a cylindrical structure, and a weighing structure supporting measurement of the magnitude of force applied to a bucket by a bucket rod and a connecting rod is formed; the bearing part comprises a force-sensitive circular ring, one side of the force-sensitive circular ring is fixedly connected with a resistance strain gauge, and the resistance strain gauge is electrically connected with a PCB; the weighing device further comprises an angle sensor fixedly connected to the middle of the connecting rod, and a measuring structure supporting measurement of the included angle between the connecting rod and the horizontal direction is formed; the weighing device is electrically connected with a central processing unit, a processing device supporting receiving and processing of electric signals of the weighing device is formed, and the problems that in the prior art, after sensors arranged on all parts of an excavator weighing device are gathered in the calculation process, a large number of measurement errors are introduced, and the overall measurement error is large are solved, and when the bucket is replaced, the bucket is inconvenient to replace, and the installation is tedious.
本发明涉及挖掘机称重技术领域，尤其涉及一种防过载式挖掘机称重装置，包括称重装置，所述称重装置包括筒状结构的承重部，形成支持分别测量斗杆和连杆对铲斗施加力的大小的称重结构；所述承重部包括力敏圆环，所述力敏圆环的一侧固定连接有电阻应变片，所述电阻应变片电性连接有PCB板；所述称重装置还包括被配置为固定连接于连杆中部的角度传感器，形成支持测量连杆与水平方向夹角的测量结构；所述称重装置电性连接有中央处理器，形成支持接收并处理称重装置的电信号的处理装置，解决现有技术中的挖掘机称重装置在各部件设置的传感器在计算过程中汇总之后，会引入大量的测量误差，导致整体测量误差极大，且更换铲斗时不便更换，安装繁琐的问题。
