Изобретение относитс к добыче угл с помощью очистных комплексов, включающий механизированные крепи, и может быть использовано при добыче .полезного ископаемого подземным способом.The invention relates to the extraction of coal with the help of refining complexes, including mechanized supports, and can be used in the extraction of minerals by the underground method.
Известна секци шахтной механизированной крепи, включающа основание, ограждение, гидростойку и силовой домкрат. В этой секции автоматизаци удержани ограждени у забо на одинаковом рассто нии достигаетс тем, что основание выполнено с продольным пазом, в котором установлен с возможностью перемещени валик,ук репленный на. ограждении П1,A known section of mine mechanized lining, including the base, fencing, hydraulic post and power jack. In this section, automating the retention of the fence at the same distance is achieved by the fact that the base is made with a longitudinal groove in which the roller is installed, which is movable on the base. fencing P1,
Недостатком известного устройства вл етс то, что в период разгрузки секции ограждение движетс в сторону обрушенных пород, что ведет либо к невозможности ее осадки, либо к деформации ее элементов.A disadvantage of the known device is that during the period of unloading the section, the fence moves towards the collapsed rocks, which leads either to the impossibility of its settlement, or to the deformation of its elements.
Наиболее близкой к предлагаемой по технической сущности и достигаемому результату вл етс секци механизированной крепи, включающа козырек с подвижной частью, шарнирно соединенные между собой перекрытие и основание, механизм компенсации положени козырька, гидростойку , гидродомкрат и гидравлические св зи 121.Closest to the proposed technical essence and the achieved result is the mechanized support section, which includes a visor with a movable part, the overlapping and the base hinged between each other, the mechanism for compensating the position of the visor, hydraulic post, hydraulic jack and hydraulic connections 121.
Недостатком известной конструкции вл етс чрезмерное нагружение элементов крепи при повороте козырька относительно перекрыти вследствие резкого изменени конфигурации кровли или концентрации нагрузки на забойную часть козырька, а также наличие множества рычагов и шарниров, делающее конструкцию громоздкой и трудоемкой в изготовлении.A disadvantage of the known construction is the excessive loading of the lining elements when the visor is rotated relatively to overlap due to an abrupt change in the roof configuration or concentration of the load on the downhole part of the visor, as well as the presence of multiple levers and hinges, which makes the design bulky and time consuming to manufacture.
Цель изобретени - упрощение конструкции и повышение надежности работы секции.The purpose of the invention is to simplify the design and increase the reliability of the section.
Поставленна цель достигаетс тем, что механизм компенсации положени козырька выполнен в виде двухThe goal is achieved by the fact that the mechanism for compensating the position of the visor is made in the form of two
