Abstract

Универсальный погрузчик-экскаватор относится к области строительных, дорожных и сельскохозяйственных машин, предназначенных для проведения погрузочно-разгрузочных работ. Универсальный погрузчик-экскаватор включает самоходное шасси с кабиной оператора, стрелу с надставкой, гидроцилиндр подъёма стрелы, гидроцилиндр изменения угла между стрелой и надставкой, рабочий орган. Новым является то, что стрела и надставка выполнены телескопическими и снабжены гидроприводом телескопирования, при этом надставка размещена на концевом телескопическом звене стрелы, а на раме погрузчика установлен фиксатор поворотной колонны для работы фронтальным способом. Для изменения угла между стрелой и надставкой установлен гидроцилиндр поворота надставки стрелы, корпус которого шарнирно соединён со стрелой, а шток шарнирно соединён с надставкой стрелы. Кабина оператора имеет гидропривод поворота в положение "вперёд" или "назад" для выполнения погрузочных работ фронтальным способом или способом поворотной стрелы. Такое выполнение позволяет объединить в одном устройстве возможности погрузчика, работающего фронтальным способом с возможностями погрузчика, работающего экскаваторным способом.Universal loader-excavator belongs to the field of construction, road and agricultural machinery designed for loading and unloading. The universal excavator loader includes a self-propelled chassis with an operator's cab, a boom with an extension, a hydraulic cylinder for lifting the boom, a hydraulic cylinder for changing the angle between the boom and an extension, a working body. New is that the boom and extension are made telescopic and equipped with a telescoping hydraulic drive, while the extension is placed on the end telescopic link of the boom, and the locking pivot column is mounted on the loader frame for frontal operation. To change the angle between the boom and the extension, the hydraulic cylinder of the boom extension is installed, the body of which is pivotally connected to the boom, and the rod is pivotally connected to the boom extension. The operator's cabin has a hydraulic actuator turning to the “forward” or “backward” position for loading operations using the frontal method or the swiveling boom method. This embodiment allows combining the capabilities of a front-end loader with the capabilities of an excavator-powered loader in one device.
