Abstract
Изобретение относитс к горному делу и может быть использовано дл креплени выработок. Цель - снижение трудоемкости установки зат жки на спецпрофиле рам (СР) креста. Продольные 1 и поперечные 2 стержни (С) зат жек соединены между собой. Концы С 1 изогнуты по форме внутренней поверхности одной из стенок и днища СР. На зат жке одним концом жестко закреплен прутковый фиксатор 6, другой конец которого изогнут. При установке зат жки ее надевают на СР. При этом изогнутые концы С 1 вход т внутрь СР, а изогнутый конец фиксатора 6 охватывает фланец СР. Последнюю вместе с зат жкой поднимают стрелой крепеустановщика и ввод т концы С 1 ранее установленной зат жки внутрь возводимого СР. 3 ил.The invention relates to mining and can be used for fastening workings. The goal is to reduce the laboriousness of installing the fixture on the special profile of frames (CP) of the cross. Longitudinal 1 and transverse 2 rods (C) are connected to each other. The ends C 1 are curved to the shape of the inner surface of one of the walls and the bottom of the CP. A bar clamp 6 is rigidly fastened on the end with one end, the other end of which is bent. When installing the plug, it is worn on the CP. In this case, the curved ends C 1 enter inside the CP, and the curved end of the retainer 6 covers the flange CP. The latter, together with the puff, is raised by the boom of the fastener and the ends C 1 of the previously installed puff are inserted inside the erected CP. 3 il.

.Изобретение относитс к горной промышленности, в частности к креплению горных выработок рамной крепью нз спехщрофил .The invention relates to the mining industry, in particular to the fastening of mine workings with frame support in the case of special industrial structures.
Цапь изобретени - снижение трудоемкости установки зат жки на спецпрофиле рам крепи и повышение ее несущей способности.The invented foot is a reduction in the laboriousness of installing the fixture on the special profile of lining frames and increasing its carrying capacity.
На фиг.1 изображена зат жка, общий вид; на фиг.2 - зат жка на рамах крепи из спецпрофил ;на фиг.З - схема установки зат жки в выработке крепеустановщиком.Figure 1 shows a puff, general view; Fig. 2 shows a puff on the frames of lining from a special profile; Fig. 3 is a schematic of the installation of a puff in the working of a fastener.
Зат жка состоит из продольных 1 и поперечных 2 стержней, соединенных между собой, например, с помощью сварки о Концы 3 продольных стержней изогнуты по форме внутренней поверхности одной из стенок 4 и днища 5 спецпрофилей рам крепи. На одном конце зат жки к продольному стержню жестко прикреплен прутковый фиксатор 6. Другой конец фиксатора вьшол- нен изогнутым с возможностью охвата фланца 7 спецпрофил рамы крепи.The hole consists of longitudinal 1 and transverse 2 rods interconnected, for example, by welding. The ends of the 3 longitudinal rods are bent according to the shape of the inner surface of one of the walls 4 and the bottom 5 of the special profiles of the support frames. At one end of the fastener, a rod-shaped clamp 6 is rigidly attached to the longitudinal rod. The other end of the clamp is made curved to cover the flange 7 of the special profile of the support frame.
Процесс креплени межрамного пространства заключаетс в следующем.The interframe mounting process is as follows.
На устанавливаемый элемент рамы крепи предварительно надевают зат жку так, что ее изогнутые концы вход т внутрь устанавливаемого элеменThe support element to be mounted on the frame element is pre-worn so that its curved ends enter inside the installed element.

та, а загнутый конец фиксатора охватывает фланец спецпрофил . Устанавливаемый элемент рамы крепи вместе с консолью, размещенной на нем зат жкой ,помещают в гнезда стрелы 8 крепеустановпщка 9 и поднимают его к кровле выработки. При размещении крепи концы ранее установленной за- 10 т жки ввод т внутрь спецпрофил этого элемента крепи.that, and the bent end of a clamp covers a special profile flange. The installed frame element of the support, together with the console, placed on it by an anchor, is placed in the seats of the boom 8 of the mounting set 9 and raised to the roof of the excavation. When placing the lugs, the ends of the previously installed charge are inserted into the special profile of this element.
