Description

Изобретение относитс к горному делу, а именно к зат жкам дл крепей горизонтальных i наклонных горных выработок.The invention relates to mining, in particular to puffs for the supports of horizontal i inclined mine workings.

Известны зат жки дл крепей горных выработок, состо щиеив стеклопластика или перекрыти , выполненного из рулонного материала , расположенного на рамах Ij и J2JKnown tightening for support of mine workings, consisting in fiberglass or overlap, made of roll material, located on the frames Ij and J2J

Недостатками этих конструкций вл етс необходимость выполнени трудоемких ручных операций при нат жении зат жек вдоль выработки и закреплени их на элементах крепи.The disadvantages of these structures is the need to perform time-consuming manual operations when pulling the cables along the production and fixing them on the support elements.

Целью изобретени вл етс снижение трудоемкости возведени крепи и сокращение времени креплени выработок.The aim of the invention is to reduce the laboriousness of the erection of the lining and reduce the time of fixing workings.

Это достигаетс тем, что один конец перекрыти снабжен манжетами дл креплени его на рамах крепи, а второй - эластичными стержн ми.This is achieved by the fact that one end of the overlap is provided with cuffs for fastening it onto the support frames, and the other end with elastic rods.

На фиг. 1 изображен общий вид зат жки с крепью; на фиг. 2 даны отдельные узлы зат жки (А -А, Б -Б и В -В).FIG. 1 shows a general view of the fastener with fastening; in fig. 2 gives separate knot knots (A-A, B-B and B-B).

Зат жка состоит из перекрыти I из рулоииого материала, манжет 2 и эластичиых стержней 3. Манжеты 2 выполнены из рулонного материала и закреплены, например , прокладками 4 с зажимами 5. Эластичные стержни 3 могут быть закреплены на конце перекрыти любым способом, например , манжетами из рулонного материала. Технологи монтажа предлагаемой зат жки на рамах крепи и ее работа заключаетс в следующем.The gland consists of an overlap I of the roll material, cuffs 2 and elastic rods 3. The cuffs 2 are made of rolled material and secured, for example, with gaskets 4 with clips 5. The elastic rods 3 can be fixed at the end of the overlap in any way, for example, with cuffs roll material. The mounting technique of the proposed fixture on the support frames and its operation is as follows.

Зат жка может моитироватьс либо на отдельных рамах крепи (например, металлических ), либо служить составной частью секционных крепей. Моитаж проводитс как непосредственно в шахте, так и на поверхности (на заводе). При монтаже крепи перекрытие I из рулонного материала зат жки с помощью манжет 2, нат гиваетс , например , на две рамы крепи 6 и фиксируютс на них. Один конец перекрыти 1 зат жки с эластичным стержнем 3 свободен.Insertion may be motivated either on separate support frames (for example, metal), or to serve as an integral part of sectional supports. Moitage is carried out both directly in the mine and on the surface (at the factory). When mounting the support, the overlap I of the web material of the tightening with the help of the cuffs 2 is tightened, for example, onto two frames of the support 6 and fixed to them. One end of the overlap of 1 puff with elastic rod 3 is free.

behind the previous one so that the free side of the previous one with the elastic rod at the end went to the new frame and fixed the tightening with the help of this elastic rod. The remaining frames are similarly molded. Zatka works as follows. After the mounting of the frame, the supports are wedged and tightened. With the appearance of rock pressure, the puff enters into work and is held tight by cuffs and elastic rods, which are pressed into the puffs of the following frames and at the same time compressed themselves, creating a single working system. The proposed fastener design makes it possible to use it widely: it does not sag, and at the same time it is convenient for installation, etc. The use of the fastener of this design allows to mechanize the installation process of the arch and provides wide perspectives for the creation of sectional supports mounted on the surface of a mine or at the factory . Claims for support of mine workings, consisting of a slab made of roll material located on the frames, characterized in that, in order to reduce the labor intensity of fixing and shorten the time of mine workings, fitted with cuffs for fastening The frames are supported, and the second - by elastic rods.
