ПРИКРЕПЛЕНИЕ ТКАНЕВОЙ ОБОЛОЧКИ К КАБЕЛЮ СВЯЗИ

Изобретение относится к способу прикрепления тканевой оболочки к обычному кабелю связи. Технический результат изобретения заключается в облегчении вставки тканевой оболочки в кабельный канал и надежности закрепления кабеля. Для достижения технического результата устройство для ввода в кабельный канал содержит кабель и тканевую оболочку, проходящую в продольном направлении вдоль кабеля. Оболочка закреплена вокруг кабеля посредством дополняющих друг друга соединителей, которые проходят снаружи относительно краев оболочки. Указанные соединители могут иметь форму, соответствующую многим конфигурациям, включая, среди прочих, крючок и прорезь, шар и гнездо, крючок и петлю, а также зубцы механической застежки. 3 н. и 7 з.п. ф-лы, 6 ил.

УСТРОЙСТВО ДЛЯ ПРЕДУПРЕЖДЕНИЯ ПОВРЕЖДЕНИЯ КАБЕЛЕЙ ПРИ ПРОКЛАДКЕ КАБЕЛЬНЫХ ЛИНИЙ

В заявке описано устройство, решающее задачу предупреждения повреждения кабелей в процессе прокладки кабельных линий. Нагрузка, которую может при натяжении выдержать тот или иной кабель, зависит от типа кабеля и количества одновременно протягиваемых кабелей. В изобретении предлагается расположенная между прокладываемым кабелем и тянущим тросом магнитная муфта, которая расцепляется при натяжении кабеля с определенным усилием (которое не должно превышать допустимое усилие, заданное изготовителем кабеля). 10 з.п. ф-лы, 3 ил.

СПОСОБ РАЗМЕЩЕНИЯ КАБЕЛЯ ПОД ПЛИТОЙ

Изобретение относится к электротехнике, в частности к способу размещения вслепую кабеля под плитой 14, например плитой, закрывающей бункер для хранения ядовитых отходов, между двумя отверстиями 24, 34. Кабель 28 опускают через одно из отверстий 24 и пушку 38 через другое отверстие 34. Мишень 42 и пушку 38 поворачивают в направлении друг друга и затем выстреливают из пушки снаряд, такой как гарпун 40, в направлении мишени после прикрепления к гарпуну 40 пенькового каната 44. После подъема мишени 42 над плитой 14 и отсоединения гарпуна присоединяют кабель к другому концу пенькового каната и протягивают пеньковый канат через отверстие 24, пока не поместят кабель на место. Техническим результатом предложенного способа является создание способа, обеспечивающего размещение троса под плитой между двумя отверстиями в плите, расположенными на определенном расстоянии друг от друга, вслепую, без вмешательства человека под плитой. 13 з.п. ф-лы, 4 ил.

Cable conduit

A cable conduit of thermoplastics material has internal ribs of serpentine longitudinal shape to allow cables to slide easily over the internal surface. The conduit has an internal radius r set at a given angle of rotation a. In a linearly arranged cable conduit with a cable to be fed contact faces of rib contact width b arise at contact points between sliding ribs and cable jacket of the cable to be fed. The sliding ribs extend in waveshape and form reversal zones between sections with constant angle of rotation a. The rib contact width b, the number of sliding ribs equidistantly distributed over the circumference of the conduit inner wall, the tube inside radius r, and the length LK of the rib contact sections between reversal zones satisfy the equation Ar = 0.16 b<2>z LK. The angle g, measured in radians, of the gliding ribs' lead as measured on the conduit inner wall, satisfies the equation g = ra/LK. ...
