Description
Гидравлические стойки из стеклопластики дл креплени очистных забоев известны.Hydraulic posts made of fiberglass for fastening the working faces are known.
Отличие описываемой стойки заключаетс в применении в гидростойке нераст жимого баллона из эластичных полиамидов (капрона или нейлона). Такое выполнение стойки обеспечивает необходимую герметичность труб из стеклошпона, устран ет необходимость применени уплотнений в виде манжет, а также исключает трение выдвижной части стойки непосредственно по стеклошпону в услови х рабочего давлени .The distinction of the described rack consists in the use of an inextensible balloon made of elastic polyamides (nylon or nylon) in a hydrostatic stand. Such an embodiment of the rack provides the necessary tightness of glass sponge pipes, eliminates the need to use seals in the form of cuffs, and also eliminates friction of the sliding part of the rack directly over the glass spike under conditions of operating pressure.
На чертеже схематически изображена гидравлическа стойка из стеклопластики.The drawing schematically shows a hydraulic rack made of fiberglass.
Описываема стойка состоит из трубчатого основани 1, в котором помещен нераст жимый баллон 2, выполненный из эластичных полиамидов (капрона или нейлона) и выдвижной трубчатой части 3 стойки. Обе части стойки выполнены из стеклопластики.The described stand consists of a tubular base 1 in which an unstretchable cylinder 2 made of elastic polyamides (nylon or nylon) and a retractable tubular part 3 of the stand are placed. Both parts of the rack are made of fiberglass.
Верхний конец баллона закреплен на нижнем конце трубы выдвижной части, здесь же монтируютс клапаны и система 4 управлени стойкой.The upper end of the cylinder is fixed to the lower end of the tube of the sliding part, valves and the rack control system 4 are also mounted here.
При работе стойки выдвижна часть опускаетс вниз, баллон как бы выворачиваетс , при этом внутренн поверхность его вл етс направл ющей выдвижной части.When the stand is in operation, the sliding part is lowered down, the cylinder is turned inside out, and its inner surface is the sliding guide part.
Предмет изобретени Subject invention
Гидравлическа стойка из стеклопластики дл креплени очистных забоев, отличающа с тем, что, с целью обеспечени необходимой герметичности труб из стеклощпона, устранени необходимости применени уплотнений в виде манжет, исключени трени выдвижной части стойки непосредственно по стеклошпону в услови х рабочего давлени , в гидростойке применен нераст жимый баллон из эластичных полиамитов (капрона или нейлона).A hydraulic rack made of glass-reinforced plastics for fixing cleaning faces, characterized in that, in order to provide the necessary tightness of pipes made of glass case, eliminate the need to use seals in the form of cuffs, eliminate the friction of the sliding part of the rack directly on the glass spike under the conditions of working pressure, Pressure cylinder of elastic polyamite (nylon or nylon).
