    摘要: The present invention discloses a self-detection device for a liner plate of a hoisting container and a detection method. The device mainly includes: a frame, a baffle-type hoist conveyor, a horizontal conveyor, a loading hopper assembly, an unloading hopper assembly, a liner plate assembly, and a hoisting container system. The loading hopper assembly is fixedly mounted to an upper right end of the frame, the unloading hopper assembly is fixedly mounted to a lower left end of the frame, the hoisting container system is arranged on an upper left portion of the frame and above the unloading hopper assembly, and the liner plate assembly is provided inside the hoisting container system. A feed port of the baffle-type hoist conveyor is connected to an unloading port of the unloading hopper, and a discharge port thereof is joined to a loading port of a loading hopper; and a feed port of the horizontal conveyor is connected to an unloading port of the loading hopper, and a discharge port thereof is arranged at a feed port on an upper end of the hoisting container system. The self-detection liner plate can simulate an impact, friction, and wear behavior on a liner plate of a hoisting container in an actual loading process; and can measure in real time an impact force and friction force bored by the liner plate when a material falls down to impact on the liner plate. In addition, the self-detection liner plate enables continuous loading of materials.
