[0018] Figure 3 This is a circuit schematic diagram of the utility model. DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-Figure 3 As shown, a tailings brick quality inspection device based on mechanical and thermal imaging analysis includes a mounting platform 1, a sealed space is provided on the upper part of the mounting platform 1, a mechanical loading structure 3 is fixedly provided on the top of the sealed space, the mechanical loading structure 3 includes a loader 301, a hydraulic device 302, and a pressure cap 303 arranged in sequence from top to bottom, the loader 301 is fixed on the top of the sealed space, the loader 301 is electrically connected to the hydraulic device 302, the hydraulic device 302 is connected to the pressure cap 303, an infrared thermal imager 304 and a camera 305 are provided at the side position of the mechanical loading structure 3 in the sealed space, and the infrared thermal imager 304, the camera 305 and the loader 301 are electrically connected to the controller respectively.

[0021] A material weighing structure 2 is provided on the left side of the sealed space, and the material weighing structure 2 includes a base, a mechanical sensor 201 and a pad 202. The base is fixedly installed on the left side of the sealed space, and a touch screen 203 and a control button 205 are provided on the base. The touch screen 203 and the control button 205 are electrically connected to the controller. The pad 202 is placed on the top of the base, and four mechanical sensors 201 are evenly distributed between the pad 202 and the base, which can ensure the flatness of the weighing platform surface to the greatest extent. The mechanical sensor 201 is electrically connected to the controller. During quality inspection, the weight of the tailings brick is obtained by the mechanical sensor 201, and the average weight data is displayed on the touch screen 203, thereby achieving the effect of facilitating the operator to obtain data.

[0022] The pad 202 is engraved with a standard scale 204, which can measure the size of the tailings brick and verify the flatness of the brick body.

[0023] A stress sensor 306 is disposed at the bottom of the pressure cap 303 , and the stress sensor 306 is electrically connected to the controller.

[0024] The bottom of the mounting platform 1 is provided with an anti-skid pad 4 to improve the gripping ability and prevent sliding.

[0025] Since the uniaxial compression test may produce some tailings brick debris, the right bottom of the sealed space is set as a landslide 101, and the bottom of the landslide 101 is hinged with an acrylic plate 102. The sealed space is opened or closed by opening or closing the acrylic plate 102, so as to facilitate the placement and processing of the semi-finished tailings bricks before and after quality inspection and accurately observe the operation of the internal machinery of the device. At the same time, the touch screen 203 can also be used as the device control end, playing the role of controlling and displaying the quality inspection process and quality inspection status.

[0026] The working process of the utility model is as follows: when quality inspection of the semi-finished tailings brick is carried out, the power is turned on, the tailings brick is placed on the pad 202, the four mechanical sensors 201 average the detected information, and display the weight on the touch screen 203, and at the same time, the high-precision standard scale 204 engraved on the pad 202 can also be used to complete a relatively accurate size measurement. Then open the acrylic plate 102, place the weighed tailings brick in a standard manner directly under the pressure cap 303, close the acrylic plate 102, turn on the on / off key and the down key of the control button 205, and transmit the signal to the loader 301 to perform the compression loading operation. After receiving the control signal of the loader 301, the hydraulic device 302 slowly descends with the pressure cap 303 to compress the tailings brick. At the same time, the infrared thermal imager 304 senses the ambient heat for thermal imaging, thereby judging the stress concentration phenomenon during the compression process of the brick body; because the brick body is deformed during the compression process, the camera 305 irradiates the surface of the brick body with ordinary white light or natural light, and through high-speed shooting, data image processing of the displacement and strain of the white light or natural light on the brick body, the flatness and apparent performance of the tailings brick are judged; during the compression process, the pressure cap 303 will move according to the preset maximum downward displacement. Among them, the stress sensor 306 can detect in this process, sense the peak value of the brick body stress by setting the shutdown parameters, and gradually stop the compression operation. At the same time, the operator can also pause and restore the compression process at any time through the control button 205. The above operations standardize the quality inspection process and improve the quality inspection accuracy, so that the quality inspection has quality and records.
