Description

Пре|дмеро;м изобретени   вл етс  устройство дл  расширени  резиновых шлангов перед укладкой в них электрических проводов, позвол юш;ее облегчить работу ло протаскиванию провода через шланг.The invention is a device for expanding rubber hoses before laying electrical wires in them, allowing us to facilitate the work of pulling the wire through the hose.

Особенностью такого устройства  вл етс  возможность расширен1и  шланга o HOiepeMeHiHO по всей дл,ине, что достигаетс  выполнением шланга в виде трубы е двойными станками, между которыми создаетс  разреженное пространство. Во внутреннюю полость трубы, сообщающуюс  с пространст|вом между стенками через отверсти  по внутретней станке, вводитс  шлак), который прит гива сь к после(, расшир ето .The peculiarity of such a device is the possibility of expanding the hose o HOiepeMeHiHO over the whole for, which is achieved by making the hose in the form of a pipe e with double machines between which a rarefied space is created. Slag is introduced into the internal cavity of the pipe, which communicates with the space between the walls through the holes through the internal machine tool, which attracts after (expanding).

Пре/длагаемое устройство (см. чертеж) выполнено в виде укладываемой на кро«,штейны / цилиндрической трзбы 2 с двоимыми стенками. Внутренн   стелка трубы по всей поверхности имеет отверст1и  3. Диаметр виутренней полости трубы несколько больше диаметра резинового шл 1кга 4. Шланг вводитс  в трубу и с обеих сторон закрываетс  пробками 5 и 6, раст лйвающими концы шланга и прижимающими их к внутренней стенке трубы. Пространство .между сте/нками трубы сообщаетс  трубопроволом 7 через кран 8 с вакуумной системой, состо щей из ресивера .9, и сое1динанного с ним трубопровода 10 вакуумиого насоса (на чертеже не показан).The proposed device (see drawing) is made in the form of a matte / cylindrical connection 2 with double walls. The inner tube of the pipe has a hole through the entire surface. The diameter of the inner cavity of the pipe is slightly larger than the diameter of the rubber tube 1kg 4. The hose is inserted into the pipe and is closed on both sides by plugs 5 and 6, which stretch the ends of the hose and press them to the inner wall of the pipe. The space between the pipes is connected by pipeline 7 through valve 8 with a vacuum system consisting of a receiver .9 and a pipeline 10 of a vacuum pump connected to it (not shown).

При открытии крала 5 в простр:анстве меледу стенками трубы создаетс  разрежение, вследствие чего резиновый щланг всей своей поверхностью прит гиваетс  к внутренней сте/нке трубы. Тем самым ш.ланг расшир етс  и обеспечивает возможность свободного введени  в него скрученного провода. Пере/д водом провода пробки 5 vi 6 вынимают.When the valve 5 is opened, a vacuum is created in the space of the meleda by the walls of the pipe, as a result of which the rubber hose attracts its entire surface to the inner pipe wall. In this way, the shanlang expands and allows the twisted wire to be freely introduced into it. Reed / d water wires plugs 5 vi 6 removed.

При наличии в шланге 110зрежде)ний (отверстий) он не раст гиваетс  и оказываетс  (непригодным дл  укладкги в нем провода.If there are injuries (holes) in the hose 110, it is not stretched and turns out to be (unsuitable for laying wires in it.

После укладки в шланг скручашвого провода закрываетс  кран 8 и открьиваета  кран 11, в результате чего шланг возвр1ащаетс  в исходное положение и при этом плотио обхватывает провод.After putting the twisted wire into the hose, the valve 8 is closed and the valve 11 is turned off, as a result of which the hose returns to its original position and at the same time the flesh clasps the wire.

Такнм образо;м, предлагаемое устройство позвол ет упростить укладку электрическ-их провддюв в резиновые шланги, обеспечивает их сохранность IH одвовремеино используетс  дл  опр е|Делени  водонепрокицаемости шлангов.So, the proposed device allows to simplify the installation of electrical conduits into rubber hoses, ensures their safety. IH is used at once to determine the water resistance of hoses.
