Abstract

Изобретение относитс к механи.- зированным креп м очистных забоев и вл етс усовершенствованием секции механизированной крепи (СМК) по авт. св. № 1102976. Цель - повышение надежности работы СМК на т желых кровл х . Дл этого в верхней части пере крыти 1 с внешней стороны выполнены упоры 19. Последние взаимодействуют со скосами 18 на наружных проушинах 17 наставки 8. Наставка 8 закреплена на перекрытии 1 ос ми 10 на опорах 11, имеющих гнезда с пазами. Центр пазов размещен ниже осей 10, а в гнездах пальцами закреплена ось, устанавливаема через пазы и соеди- н. юща гидропатрон 16 с перекрытием 1. Это обеспечивает достаточный ход гидропатрона 16 и его несущую способность , что снижает сжатие гидропатрона нежестко, В результате этого исключаетс опрокидьтание козьфька 2 и наставки 8 на забой. Разгрузка креплени наставки 8 на перекрытии 1 обеспечиваетс проушинами 17, опирающимис скосами 18 на упоры 19, 3 ил. К)The invention relates to mechanized support for working faces and is an improvement of the mechanized support section (QMS) according to the author. St. No. 1102976. The goal is to increase the reliability of the QMS on heavy roofs. To do this, in the upper part of the overlap 1, stops 19 are provided on the outer side. The latter interact with the bevels 18 on the outer lugs 17 of the attachment 8. The attachment 8 is fixed on the overlap of 1 axis 10 on the supports 11 having slots with slots. The center of the grooves is located below the axes 10, and in the sockets with fingers, an axis is fixed, which is installed through the slots and connectors. Overlapping hydropatron 16 overlap 1. This ensures a sufficient travel of hydropatron 16 and its carrying capacity, which reduces the compression of hydropatron loosely. As a result, the tilting of goat 2 and set-up 8 on the bottom face are excluded. The unloading of the attachment of the attachment 8 to the overlap 1 is provided by the lugs 17 supported by the bevels 18 on the stops 19, 3 or more. TO)

Claims

The invention relates to the mining industry, namely to mechanized lids for clearing faces, and is an improvement of the known section of mechanized lining described in ed. St. No. П02976. The aim of the invention is to increase the reliability of the support section on heavy roofs. Figure 1 shows the mechanized support section, side view; figure 2 - section aa in figure 1; on fig.Z - section bb in fig.

2. The mechanized lining section contains a front cover 1, a goat guard 2 with supports 3, a sliding wiper blade cleaver 4 and a hydraulic jack 5, a pressure beam 6 with movable locks 7. A cover 8 is rigidly fixed on the overlap 1, on which is hinged a visor 2, made in the form of hollow boxes with supports 3, having an edge with an inclined groove 9 located at an angle to the vertical. The visor 2 is connected to the visor 2 boxes, interconnected in the front part and having a clearance N. between the upper sheet of the visor N. The visor 2 is connected to the cleaver 4 by a hydraulic jack 5 placed between the visor boxes. The scooper 4 lies on the beam 6, which covers the ribs of the Poles 3, and the lugs of the beam with the ribs of the supports are connected with movable clamps 7 with the ability to move them along the grooves 9. The cradle 8 is fixed on the overlap 1 of the axle 10 on the poles 11, having slots 12 with grooves 13, open to the face, the center of which is located below the axes 10, and in the nest 12 with fingers 14, an axis 15 is fixed, installed through the grooves 13 and connecting the hydropath by 16 overlapping. The attachment 8 has outer lugs 17 with bevels 18 at the rear ends. 232 resting on stops 19 mounted on the floor. Section mechanized lining works as follows. When stabbing the roof at the bottom, spreading along the length of the lava, in most cases, to tens of meters, in order to prevent the block of rocks from falling into the working space under the lining, the lining sections move with the raised grinder 4. Retaining the block from collapsing and preventing the cap from tipping over 2 on the bottom is made by sampling the gap H between the pin and the top sheet of the visor 2 by spreading the hydraulic cartridge 16 into the beam 6. By deflecting the hydraulic cartridge 16 from the vertical by an angle oi not exceeding 45 obtained by attaching the axis 15 Drops in nests 1 2, placed below the axes 10; securing the adapter 8, provides sufficient running of the hydraulic cartridge and its carrying capacity, which reduces the opatron's guide very tightly, which prevents tilting of the visor 2 and of the adapter 8 on the bottom, and relieves the mounting of the adapter on the ceiling, which is provided with external lugs 17, supported by bevels 18 on the backs 19. The claims; Section mechanized lining auth. St. No. 1102976, characterized in that, in order to increase the reliability of its operation on heavy roofs, the overlapping of the section in the upper part is performed on the outside with stops, and on the inside below the axis of attachment of the attachment with slots having slots on the bottom side In this case, the linkage of the set-up with the hydraulic cartridge is made in the form of an axis mounted in the slots of the ceiling, and the guide is made with eyelets having bevels for interacting with the stops of the ceiling.
