A multi-adaptive workload change detection device and detection method

Abstract

The present invention relates to a multi-adaptive workload change detection device and detection method, wherein the detection device includes a hydraulic jack whose extension direction is consistent with the tensioning direction of the tensioning wheel and is fixedly arranged, and a tensioning wheel rigidly connected to the piston of the hydraulic jack, and the oil inlet of the hydraulic jack is connected to the hydraulic oil supply cylinder through a pipeline, and a pressure sensor and / or a pressure gauge is installed on the pipeline. The present invention converts the change of the actual load of the machine into a hydraulic system pressure change that is easy to collect through the tensioning wheel mechanism, avoiding the disadvantages of the mechanical structure when collecting by the traditional torque sensor, and improving the practicality of the detection device; the hydraulic system pressure and the tensioning wheel speed can be collected at the same time through the pressure sensor and the Hall sensor, which is convenient for the real-time display of the change curve through the host computer; the oil circuit is divided into two parts by the stop valve, which reduces the volume of the compressed oil body, makes the pressure change more obvious, and ensures the accuracy of load detection.
