The invention provides a precise metering structure for an overload device, and relates to the technical field of hoisting overload, the precise metering structure comprises a support, a hinged shaft is mounted on the support, a cradle is rotatably mounted on the hinged shaft, the cradle is located below the support, a rotating shaft is mounted on the cradle, and a load power take-off pulley is rotatably connected to the rotating shaft; a cylindrical pressing type sensor is installed on the support through a threaded hole, and the sensing end of the cylindrical pressing type sensor is connected with the hinged shaft. The metering structure has the advantages that the load power take-off pulley is installed on the lower portion, the wrap angle of the steel wire rope can be changed, reverse bending of the steel wire rope is reduced, the service life of the steel wire rope is prolonged, the load power take-off pulley can rotate and move in the axial direction through the sliding bearing, and the load power take-off effect is improved. By installing the cylindrical pressing type sensor, the metering accuracy of the overload device can be improved, the using effect of the overload device is improved, and the overall using effect is good.
本发明提出了一种用于超负荷装置的精准计量结构,涉及吊装超负荷技术领域,包括支座,支座上安装有铰轴,铰轴上转动安装有摇架,摇架位于支座的下方,摇架上安装有转轴,转轴上转动连接有负荷取力滑轮,支座上通过螺纹孔安装有圆柱压式传感器,圆柱压式传感器的传感端与铰轴连接。该计量结构的有益效果是:该装置通过将负荷取力滑轮安装到下方,能够改变钢丝绳的包角,进而减小了钢丝绳的反向曲折,提高钢丝绳的使用寿命,通过滑动轴承能够让负荷取力滑轮进行转轴向移动,进而抵消因钢丝绳卷筒出绳角变化带来的转轴向力,通过安装圆柱压式传感器,能够提高超负荷装置的计量准确性,提高超负荷装置的使用效果,整体使用效果好。
