Self-detection device for liner plate of hoisting container and detection method

A self-detection device for a liner plate of a hoisting container, comprising:

• a frame (5), a baffle-type hoist conveyor (2), a horizontal conveyor (16), a loading hopper assembly, an unloading hopper assembly, a liner plate assembly, and a hoisting container system that can move up and down, wherein the loading hopper assembly is fixedly mounted to an upper right end of the frame (5), the unloading hopper assembly (7) is fixedly mounted to a lower left end of the frame (5), the hoisting container system is arranged on an upper left portion of the frame (5) and above the unloading hopper assembly (7), and the liner plate assembly is provided inside the hoisting container system;
• a feed port of the baffle-type hoist conveyor (2) is connected to an unloading port of the unloading hopper (7), and a discharge port thereof is joined to a loading port of a loading hopper (1);
• and a feed port of the horizontal conveyor (16) is connected to an unloading port of the loading hopper (1), and a discharge port thereof is arranged at a feed port on an upper end of the hoisting container system, such that falling materials can directly impact the liner plate assembly inside the hoisting container system;
• the liner plate assembly comprises a liner plate backboard (12), a guide rail (40), a slide block (44), a liner plate (41), an impact force sensor (42), a bearing (23), and a tension-compression sensor (21), wherein the guide rail (40) is fixed on a front side of the liner plate backboard (12), the slide block (44) is arranged on the guide rail (40) and slidably connected to the guide rail (40), and the liner plate (41) is fixedly connected to the slide block (44);
• an upper end of the liner plate (41) is connected to an upper end of the liner plate backboard (12) via the tension-compression sensor (21);
• one end of the tension-compression sensor (21) is connected to the liner plate (41) with a stud bolt (43), and the other end thereof is fixedly mounted to the bearing (23) with a bolt (22);
• and one side of the impact force sensor (42) is fixed onto the liner plate backboard (12), and the other side thereof is in contact with a left plate surface of a hoisting container (11);
• and the bearing (23) comprises an upper bearing pair and a lower bearing pair, two bearings of the upper bearing pair are respectively disposed on two upper ends of the liner plate backboard (12), and the two bearings of the lower bearing pair are respectively disposed on two lower ends of the liner plate backboard (12);
• four guide grooves (24) corresponding to the bearings are symmetrically welded up and down onto the left plate surface of the hoisting container (11), such that the bearing (23) on the liner plate backboard (12) moves in the guide grooves (24);
• the tension-compression sensor (21) is used for measuring a friction force borne by the liner plate (41) when the material falls down to impact on the liner plate;
• and
• the impact force sensor (42) is used for measuring an impact force borne by the liner plate (41) when the material falls down to impact on the liner plate.
