The invention relates to the technical field of hoisting mechanisms, in particular to a crane load detection device. A crane load detection device comprises a supporting frame, a guide wheel, a steel cable, a winding shaft and a driving mechanism. The driving mechanism comprises a driving motor, a variable-speed transmission mechanism, an acceleration sensing mechanism and a variable-speed control mechanism; the driving motor drives the winding shaft to rotate through the variable-speed transmission mechanism, so that the other end of the steel cable pulls the heavy object to ascend and descend. The acceleration sensing mechanism is used for detecting the acceleration of ascending or descending of the lifted weight and controlling the variable speed control mechanism to be started when the acceleration of ascending or descending of the weight exceeds a preset value, and the acceleration of ascending or descending of the object is adjusted by changing the rotating speed of the variable speed transmission mechanism driving the winding shaft to rotate when the variable speed control mechanism is started. And the pulling force borne by the steel cable is adjusted, so that the pulling force borne by the steel cable does not exceed the preset size, and the safety of the device is guaranteed.
本发明涉及起重机构技术领域,具体涉及一种起重机载荷检测装置。一种起重机载荷检测装置包括支撑架、引导轮、钢缆、绕线轴和驱动机构。驱动机构包括驱动电机、变速传动机构、加速感应机构和变速操纵机构;驱动电机通过变速传动机构驱动绕线轴转动,使钢缆的另一端拉动重物升降。加速感应机构用于检测吊起的重物上升或下降的加速度,且在重物上升或下降的加速度超出预设值时控制变速操纵机构启动,变速操纵机构启动时通过改变变速传动机构带动绕线轴转动的转速来调节物体上升或下降时的加速度,进而调节钢缆受到的拉力,使钢缆受到的拉力不超过预设大小,保证装置的安全性。
