Description

Известны защитные щитки дл  электросварщиков с приспособлением дл  иодвода свежего воздуха, в которых ручка, выиолиенна  и виде иолого патрубка, используетс  в качестве подвод щей воздушной магистрали.Protective shields for electric welders with a device for iodine of fresh air are known, in which a handle, shaped and shaped as a chute, is used as a supply air line.

Описываемый защитный щиток снабжен вентил ционным ириспособление1М , действующим на принципе отсоса и выполненным в виде монтируемого ка внешней стороне щитка изогнутого патрубка, один конец которого снабжен раструбом, а другой конец подключен к всасываюп;ей магистрали.The described protective shield is provided with a ventilation device 1M, which operates on the principle of suction and is made as an outer side of the shield mounted curved pipe, one end of which is fitted with a socket and the other end is connected to the suction side.

При работе электросварщика с защитным щитком предложенной конструкции раструб патрубка находитс  посто нно вблизи зоны горени  дуги и обеспечивает отсос газов и пыли, образующихс  ири сварке. Это улучшает услови  работы сварщика и уменьшает загр знение воздуха , что особенно важно при работе в закрытых сосудах.When an electric welder works with a protective shield of the proposed design, the socket of the nozzle is constantly close to the arc burning zone and ensures the suction of gases and dust generated by welding. This improves the working conditions of the welder and reduces air pollution, which is especially important when working in closed vessels.

На чертеже изображен предложенный щиток в трех проекци х.The drawing shows the proposed shield in three projections.

Вентил ционное приспособление состоит из полого патрубка /, один конец которого жестко соединен с раструбом 2, а другой конец с помощью гиокого щланга 3 с выт жным устройством. Полый патрубок J, служащий одновременно ручкой дл  держани  щитка, выполн етс  из легкого сплава, например, дюралюмини , и крепитс  к внешней стороне щитка 4 обычной конструкции посредством хомутов 5 и 6. Конец патрубка, вход щий в раструб на 50 мм, с торца заглушен, и на боковой его поверхности высверлены отверсти  8 диаметром 4 мм. Диаметр патрубка 25 мм. Диаметр раструба 80 мм, его высота 100 мм. Количество отверстий на боковой поверхности конца патрубка, вход щего в раструб, 3-4 на 1 см.The ventilation device consists of a hollow pipe /, one end of which is rigidly connected to the socket 2, and the other end by means of a hypochial hose 3 with an exhaust device. The hollow nozzle J, which serves simultaneously as a handle for holding the shield, is made of a light alloy, for example, duralumin, and is attached to the outer side of the shield 4 of a conventional construction with clamps 5 and 6. The end of the nozzle, which is 50 mm in the socket, is plugged from the end , and 8 holes with a diameter of 4 mm are drilled on its lateral surface. The diameter of the nozzle is 25 mm. The diameter of the socket is 80 mm, its height is 100 mm. The number of holes on the side surface of the end of the nozzle entering the socket is 3-4 x 1 cm.
