At present, although there are many patents disclosed, such as CN102996150A, CN206766900U and CN206016840U, special mechanical devices are installed above the hydraulic support or the scraper conveyor to prevent large pieces of coal gangue rolling from causing impact damage to the personnel on the working face when the coal seam with a large dip angle is mined. But they do not have the function of preventing the impact of large pieces of coal gangue at the head of the scraper conveyor on the tail of the transfer machine and preventing them from flying out or overflowing the tail of the transfer machine

The invention discloses a gangue-blocking and anti-collision device for the head of a scraper conveyor on a fully mechanized mining face and a method for using the device. On the supporting structure of the overhead plate, including lifting system, guiding system and arresting system. The lifting system is located at the top and consists of an inner wire tube, a long screw, a ring washer, bolts and nuts and a shackle to adjust the height of the device; the guiding system is hingedly connected with the lifting system, and is mainly composed of a hanging groove at the end and a middle Suspension grooves and tooth grooves are composed of mining I-beams, which provide suspension fulcrums for the arresting system below the suspension and realize its horizontal movement; Or avoid the damage caused by coal gangue hitting or flying out. The device is simple in structure, easy to operate, can flexibly move with the advance of the working face, and has strong practicability.
Description
technical field [0001] The invention belongs to the field of mining machinery and equipment, and in particular relates to a gangue-blocking and anti-collision device for a scraper conveyor head in a fully mechanized mining face and a use method thereof. Background technique [0002] Coal is the food of industry and is mainly used in power generation, steel smelting, coal product processing and cement manufacturing in the electric power, steel, chemical and building materials industries. With the continuous deepening of my country's coal structural capacity reduction and the continuous advancement of clean coal utilization, the energy structure has been further optimized. In 2019, the national raw coal output was 3.846 billion tons, of which 76.8% came from Shanxi, Inner Mongolia, Shaanxi and Xinjiang; the total annual energy consumption totaled 4.860 billion tons of standard coal, and coal consumption was about 2.804 billion tons of The proportion of energy consumption reac...
