Abstract
Изобретение относитс к механизированным креп м очистных забоев угольных шахт, а именно к креп м дл крутых пластов средней и выше средней мощности. Цель - снижение трудоемкости передвижки. Дл этого в механизированных креп х дл крутых пластов межсекционные св зи имеют вид подпружиненных роликоопор, установленных на направл ющих 12. Направл ющие 12 св заны с гидростойками вышерасположенной секции посредством втулок 6 и кронштейнов 5. Роликоопоры установлены с возможностью перемещени вдоль оси направл ющих 12 в направлении подвигани . При разгрузке одной из секций крепи усилие по ее удержанию через кронштейны 5 и втулки 6 передаетс на подпружиненные роликоопоры, установленные на направл ющих 12. По направл ющим 12 секци скатываетс под действием собственной массы к забою. 3 ил.The invention relates to mechanized fortifications of coal mines, and in particular to supports for steep seams of average and above average power. The goal is to reduce the complexity of shifting. For this, in mechanized supports for steep seams, intersectional links have the form of spring-loaded roller supports mounted on guides 12. Guides 12 are connected to the hydraulic legs of the upstream section by means of sleeves 6 and brackets 5. direction of progress. When unloading one of the securing sections, the force to hold it through the brackets 5 and the sleeves 6 is transferred to spring-loaded roller supports mounted on the guides 12. The section 12 rolls along the guides 12 under the action of its own weight to the face. 3 il.
