Description
Изобретение относитс к горнодобывающей промышленности и может быть использовано в конструкци х металлических крепей из спецпрофил , устанавливаемых в подземных горных выработках.The invention relates to the mining industry and can be used in metal support structures of special profiles installed in underground mines.
11ель изобретени - улучшение работы крепи в податливом режиме.11el of the invention - improved support of the support in the ductile mode.
На чертеже показаны элементы крепи, соединенные узлом податливости.The drawing shows the lining elements connected by a node of compliance.
Элементы крепи 1 и 2 соединены узлом подагливости, который включает две скобы 3 с блоками 4 и гайками 5, устанавливаемые в месте нахлестки соедин емых элеменThe lining elements 1 and 2 are connected by a knotty knot, which includes two brackets 3 with blocks 4 and nuts 5, which are installed in place of the overlap of the elements connected
тов крепи. Элементы крепи имеют в местах их соединени фигурные приливы 5 и 6, в одном из которых выполнено отверстие 7. Между днищами профилей и фигурными приливами размещен податливый материал 8, например, битум.Comrade. The lining elements have curved tides 5 and 6 at their joints, in one of which a hole 7 is made. A ductile material 8, for example, bitumen, is placed between the bottoms of the profiles and the curved tides.
При работе крепи в податливом режиме возникают силы трени между днищами спецпрофилей , днищами и фигурными приливами , а также в самом податливом материале. Величину сопротивлени узла регулируют изменением диаметра и длины выпускного отверсти и изменением свойств самого податливого материала.During the work of the lining in the ductile mode, forces of friction arise between the bottoms of special profiles, bottoms and figured tides, as well as in the most pliable material. The magnitude of the resistance of the node is controlled by changing the diameter and length of the outlet and changing the properties of the most pliable material.
