(54) ПЕРЕКРЫТИЕ СЕКЦИИ ШАХТНОЙ МЕХАНИЗИРОВАННОЙ КРЕПИ жимает подпорную плиту 5 к нарушенной кровле, предотвраща  ее обру11Гё1пте; й также за счет сил горного давлени , действующих на плиту 5 через упругий элемент 6, передает значительное усилие, на завальную консоль козырька 3, котора  поджимает к кровле и ее забойнуюконсоль. Во врем  распора секции крепи происходит самоустановка по профилю кровли как забойной к(5Нсоли козырька 3, так и подпорной плиты 5. Перекрытие секции шахтной механизированной крепи такой конструкции позвол ет обеспечить наиболее полное контактирование с кровлей при приспособлении к ее профилю и активный подпор во врем  разгрузки и передвижки секции, надежно в.работе и просто по конструкции. Формула изобретени  Перекрытие шахтной механизированной кретти, включающеешаркирно закрепленный козырек, подпорную плиту, св занную одww концом с къзырьком посредством шарнирного соединени , и упругий элемент, отличающеес  тем, что, с целью улучшени  приспосабливаемости перекрыти  к кровле выработки и обеспечени  активного подпора во врем  перёдвижки секции, подпорна  плита размещена с завальной стороны перекрыти , а ее свободный конец взаимодействует через упругий элемент с козырьком, который выполнен фигурным с завальной и забойной консол ми, при этом шарнирное соединение подпорной плиты размещено в средней части козырька.

(54) THE OVERLAPPING SECTION OF THE MINE MECHANIZED STRIP presses the retaining plate 5 to the broken roof, preventing it from turning; Also, due to the rock pressure forces acting on the slab 5, through the elastic element 6, a considerable force is transmitted to the burial console of the visor 3, which presses to the roof and its bottomhole console. During the installation of the lining section, self-installation occurs along the roof profile both downhole to (5H shade visor 3 and retaining plate 5. Overlapping of the shaft mechanized lining section of this design allows for the most complete contact with the roof when adapted to its profile and active backwater during unloading and shifting of the section, reliably in the work and simply in construction. Formula of invention The overlap of the mine mechanized cretti, including a hinged visor, a retaining plate connected to one end m with a pin by means of a hinge joint, and an elastic element, characterized in that, in order to improve the adaptability of the overlap to the roof of the excavation and to provide an active backwater during the movement of the section, the retaining plate is placed on the bulkhead to overlap, and its free end interacts through the elastic element with a visor, which is made figured with zavalnoy and downhole console, while the hinged connection of the retaining plate is placed in the middle part of the visor.
