Technical Field

[0002] The coke dry quenching lifting hook is usually an important component of the coke dry quenching system. The coke dry quenching lifting hook can usually lift and transport the coke pot during the coke dry quenching process. The coke dry quenching lifting hook can be used in cooperation with the hook system of the hoist, and thus can achieve precise and stable lifting of the coke pot. When the coke dry quenching lifting hook is in use, it is usually necessary to identify the state of the lifting hook, and thus an identification camera will be used.

[0003] The identification cameras of the prior art are usually installed at the 30° position of the coke dry quenching lifting hook, and there is no temperature difference between the coke dry quenching lifting hook and the background.

Furthermore, it is not convenient to form a temperature difference between the background device and the coke dry quenching lifting hook to accurately judge the state of the lifting hook through the temperature region.

A bearing plate 7 is arranged on the side of the coke pot 3, which is beneficial to support the infrared thermal imaging camera 5 and facilitate the installation of the infrared thermal imaging camera 5. An infrared thermal imaging camera 5 is arranged on the side of the bearing plate 7. The infrared thermal imaging camera 5 is an infrared thermal imaging camera, which is beneficial to being free from the interference of environments such as sunlight and flames, and has a higher recognition accuracy. At the same time, the radiation rate on the surface of the background plate 66 is very low, and it can reflect the infrared radiation emitted from the surface of the coke pot 3 to the infrared thermal imaging camera 5. The background plate 66 of the background of the dry coke quenching lifting hook 4 in the thermal image is about 200 °C high temperature, and then is infrared received by the infrared thermal imaging camera 5.

[0025] Further, an auxiliary mechanism 6 for providing a background for the state recognition of the dry coke quenching lifting hook 4 is arranged on the side of the wall 2. The auxiliary mechanism 6 includes a keel frame 61 and a background plate 66. The keel frame 61 is beneficial to support the positioning plate 62. The number of both the keel frame 61 and the background plate 66 is 10. The background plate 66 is a stainless steel plate. The background plate 66 is beneficial to reflect the external temperature of the coke pot 3, and then form a temperature difference with the dry coke quenching lifting hook 4. During use, due to the influence of the high temperature of the internal coke lumps, the outer wall temperature of the coke pot 3 is about 200 °C to 300 °C. The high-temperature infrared thermal radiation on the outer wall is emitted to the background plate 66, and then after reflection, it reaches the lens of the infrared thermal imaging camera 5. Then, after the infrared thermal imaging camera 5 receives the thermal radiation, it forms an image. In the imaging picture, the dry coke quenching lifting hook 4 appears as a low-temperature contour, and a high-temperature contour appears in the background of the dry coke quenching lifting hook 4. The state of the dry coke quenching lifting hook 4 is judged through the intelligent neural recognition system.

The square plate 87 is conducive to supporting the fixing rod. The side of the sliding plate 83 is fixedly connected to the positioning column 84. A reinforcing column 85 is fixedly connected to the side of the sliding plate 83, which is conducive to defining the relative position between the fixing frame 82 and the fixing column 81, facilitating the increase of the stability of the limit of the fixing column 81. A second sliding groove matching the reinforcing column 85 is formed on the side of the fixing frame 82.

The outer wall of the fixing rod is slidably inserted into the sliding plate 83. A spring 86 is sleeved on the outer wall of the fixing rod. The elastic force of the spring 86 is conducive to pushing the sliding plate 83 to move, facilitating the sliding plate 83 and the positioning column 84 to return to their original positions after movement, facilitating the repeated operation of the positioning column 84. One end of the spring 86 is in contact with the square plate 87, and the other end of the spring 86 is in contact with the sliding plate 83.
