Abstract

Изобретение относитс к горной пром-сти. Цель - повышение надежности закреплени анкера и снижение его металлоемкости. Анкер дл креплени горных выработок включает штангу /Ш/ 1 с упором 2 на глубинном конце, р ды свободно установленных по длине Ш 1 распорных элементов и упорную втулку 3. Распорные элементы имеют вид состыкованных основани ми парных усеченных конусов /УС/ 4 и 5 с одинаковыми вершинами. Диаметр основани УС 4 меньше диаметра основани УС 5. В р ду распорных элементов УС 5 на глубинном конце Ш 1 повернуты вершинами к ее упору 2, а в р ду на противоположном конце Ш 1 - в обратную сторону. Между р дами разнонаправленных парных УС 4 и 5 установлена упорна втулка 3. Последн жестко прикреплена своими концами к внутренней поверхности крайних в р ду УС 6 и 7 с большим основанием. В торцах втулки 3 выполнены прорези. В пространстве между смежными УС 5 и УС 4 могут быть установлены эластичные прокладки 9. При установке анкера его ввод т в скважину с оставлением зазора между опорной плиткой 11 и поверхностью кровли на половину высоты УС 5. Затем этот зазор устран ют путем зат гивани нат жной гайки 12. При этом УС 5, 6 и 7 распираютс и внедр ютс в стенку скважины. При наличии эластичных прокладок 9 они подвергаютс сжатию и прижимаютс к стенкам скважины, что усиливает распор анкера. 1 з.п. ф-лы. 2 ил.The invention relates to the mining industry. The goal is to increase the reliability of fixing the anchor and reducing its metal consumption. The anchor for fastening the mine workings includes a bar / W / 1 with a stop 2 at the depth end, a row of spacer elements 1 freely installed along the length W 1 and a stop sleeve 3. The spacers have the form of paired truncated cones / DC / 4 and 5 sec. the same vertices. The base diameter of US 4 is smaller than the base diameter of US 5. In the row of spacer elements, US 5 on the deep end of W 1 are turned to its anvil 2, and in the row on the opposite end of W 1 in the opposite direction. Between the rows of multidirectional paired WC 4 and 5, a thrust sleeve 3 is installed. The latter is rigidly attached with its ends to the inner surface of the outermost in the row of USA 6 and 7 with a large base. In the ends of the sleeve 3 is made slots. Elastic pads 9 can be installed in the space between adjacent US 5 and US 4. When the anchor is installed, it is inserted into the well, leaving a gap between the support tile 11 and the roof surface half the height of the US 5. Then this gap is removed by tightening the tension nuts 12. At the same time, CA 5, 6, and 7 are retracted and inserted into the borehole wall. In the presence of elastic pads 9, they are compressed and pressed against the walls of the well, which increases the anchor thrust. 1 hp f-ly. 2 Il.

Claims

Claim

1. Anchor for attaching mine workings, including a rod with an emphasis, a number of spacer elements freely set along the length of the rod from paired truncated cones joined by the bases with identical vertices and thrust bushings, characterized in that. what. in order to increase the reliability of fixing the anchor and reduce its metal consumption, the emphasis is placed on the deep end of the rod, and the diameter of the base of one of the pair of truncated cones is less than the diameter of the base of the other, while in the row, which is located on the deep end of the rod, the truncated cones with a large base are turned by the vertices to its stop, and in a row at the opposite end of the rod - turned vertices in the opposite direction, and the thrust sleeve is placed between the oads of multidirectional paired truncated cones and rigidly attached with its ntsami to the inner surface in the outer row of truncated cones with the larger base, and the ends of the sleeve slits.

2. Anchor pop. 1. characterized in that it is equipped with elastic gaskets located in a space bounded by adjacent truncated cones with a large base and a truncated cone with a small base installed between them.
