Description
Description MOVABLE DETECTION DEVICE FOR MIDDLE CHUTES AND APPLICATION THEREOF
Technical Field The present invention relates to a mobile central chute detection apparatus and an application of the mobile central chute detection apparatus, which belongs to the technical field of coal mining equipment.
Background Chutes are main body of a scraper conveyer and an operating track of a coal cutter. Coal and scraper chain slide in the chutes, and the chutes coordinate with hydraulic supports to accomplish chute pushing and support moving process. Chutes are one of important components of the downhole coal mining equipment. Owing to the harsh downhole working environment, the central chutes are subjected to shocks and vibrations at different degrees; in addition, since the chute sills may be out of level, the chutes may have offsets in horizontal and vertical directions; consequently, a groove profile between two chutes may be not in the same direction, thereby the scraper chain may suffer increased operating resistance when it slides in the chutes. The chutes and scrapers may be worn severely and cause shocks to the driving system as time passes, resulting in shortened service life of the scraper conveyer; moreover, it is difficult to ensure that all chutes are in the same line after accomplishing chute pushing and support moving process, and the above problem may be encountered if the level of curvature is too high. More seriously, if a dumbbell pin that connects two chutes falls out or is broken when the scraper conveyer operates, the downhole coal mining equipment cannot operate normally or even may be damaged, resulting in immeasurable consequences. Therefore, it is necessary to detect the positions of the central chutes.
At present, most central chute position detection apparatuses employ fixed sensors. However, since there are hundreds of central chutes on a scraper conveyer, a large number of sensors are required if conventional fixed sensors are used; in addition, since the circuit layout is limited owing to the harsh downhole environment, the sensors may be damaged frequently if there is no effective protective measure; moreover, the chute structure will be changed if the circuits are embedded in the chutes of the scraper conveyer.
