Стрела экскаватора

Номер: RU0000187191U1

Полезная модель относится к машинам для земляных работ циклического действия, в частности, к рабочему оборудованию одноковшового экскаватора, и может быть использована для копания, забора и разрыхления грунта вдоль каких-либо сооружений. Техническая задача - обеспечение копания под углом к оси экскаватора с возможностью поворота верхней части стрелы на угол более 90°, что позволяет расширить технологические возможности экскаватора. Поставленная задача решается тем, что стрела экскаватора, выполненная из двух частей, корневой 1 и верхней 2, соединенных с возможностью копания под углом к оси экскаватора шарниром поворота верхней части 2 относительно корневой 1 в направлении поперечном оси стрелы, снабжена шарнирным механизмом поворота верхней части 2 стрелы на угол более 90°, состоящим из вала 3 и втулки 4, где вал 3 снабжен закрепленным на корневой части 1 стрелы приводом 5 от гидромотора-редуктора с тормозным механизмом и конической зубчатой передачей 6, а крутящий момент от вала 3 на верхнюю часть 1 стрелы передается через шлицевое соединение 7. Таким образом, заявляемая полезная модель позволяет обеспечить передачу крутящего момента от привода 5 с конической зубчатой передачей 6 на верхнюю часть 2 стрелы с возможностью ее поворота на угол более 90°, что приводит к расширению технологических возможностей экскаватора. 2 ил.

What is presented is a thawing system for thermally heating an undercarriage of a machine, with the machine having an engine and a track frame. This thawing system comprises a heating element and thawing line. The heating element is powered independently from the engine, produces thermal energy for the thawing system, and can be activated and/or stay activated when the engine is not active. The thawing line is connected to the heating element, adapted to spread thermal energy from the heating element throughout the undercarriage of the machine, and is isolated from the engine. The thawing line extends from the heating element to the undercarriage of the machine via a channel, which is in the machine. Thermal energy is produced and delivered to the undercarriage of the machine when the heating element is activated.
