Abstract
Изобретение относитс к горной промышленности. Целью изобретени вл етс повышение эксплуатационной надежности анкера. Анкер содержит набор гильз 4 и консульных втулок 3, свободно надетых на гибкий несущий элемент, например канат (К) 1. Глубинный конец К заделан в главной конусной втулке 2. На К 1 размещены стакан 6 с внутренней резьбой, тарельчата пружина 8 и выпуклые шайбы 9. Выступающий конец К 1 заделан в хвостовике, представл ющем собой втулку 10. На последнюю навинчена гайка 12. На К 1 жестко установлена промежуточна втулка 13 с наружной резьбой с возможностью взаимодействи со стаканом 6. При установке анкера его ввод т в скважину в сборе. Затем вращают стакан 6. Он перемещаетс к устью скважины. При этом перемещаютс втулка 2 и конусные втулки 3 к устью скважины, а гильзы 4 - в радиальном направлении. Гильзы 4 распираютс в скважине. После этого вращением гайки 12 создают нат жение К 1. Дл извлечени анкера операции по его установке выполн ют в обратном пор дке. Промежуточна втулка 13 исключает вли ние на анкер поперечных нагрузок. Обеспечиваетс также возможность регулировани воздействующих на хвостовик анкера изгибающих нагрузок. 2 ил.The invention relates to the mining industry. The aim of the invention is to increase the operational reliability of the anchor. The anchor contains a set of sleeves 4 and consul sleeves 3, loosely mounted on a flexible carrier, for example a rope (K) 1. The depth end K is embedded in the main taper sleeve 2. On K 1 there is a glass 6 with an internal thread, a spring 8 and convex washers 9. The protruding end of K 1 is embedded in the shank, which is the sleeve 10. The nut 12 is screwed onto the last one. On K 1, the intermediate sleeve 13 with external thread is rigidly mounted with the possibility of interacting with the cup 6. When installing the anchor, it is inserted into the well assembly . The canal 6 is then rotated. It moves to the wellhead. When this moves the sleeve 2 and the tapered sleeve 3 to the wellhead, and the sleeve 4 in the radial direction. The sleeves 4 extend in the well. Thereafter, the rotation of the nut 12 creates a tension K 1. To remove the anchor, the operations for its installation are performed in the reverse order. The intermediate sleeve 13 eliminates the effect of lateral loads on the anchor. It is also possible to control the bending loads acting on the anchor shank. 2 Il.
