Abstract
Изобретение относитс к строительным машинам, а именно к одноковшовым экскаваторам и погрузчикам. Цель изобретени - расширение эксплуатационных возможностей путем снижени удельного давлени на грунт. Машина имеет опоры 1, которые выполнены из эластичных емкостей. Емкости соединены с пневмосистемой, выполненной из расположенных под поворотной платформой и закрепленных-к раме машины кольцевых трубопроводов 11 и 12, которые соответственно имеют впускной 14 и выпускной 18 клапаны. Штоки 15 и 19 клапанов 14 и 18 соединены нажимными кольцами 16 и 20. На поворотной платформе закреплены гидротолкатели 21 и 22. При работе опоры 1 с помощью гидроцилиндров 7 опускаютс на грунт. Затем срабатывает гидротолкатель 21, впускные клапаны 14 открываютс и сжатый воздух поступает в емкости, которые вл ютс опорами. Дл передвижени машины сжатый воздух стравливаетс из емкостей, опоры 1 поднимаютс гидроцилиндрами 7 и машина переходит на новую позицию. Затем цикл повтор етс . 9 ил. fcThe invention relates to building machines, namely single-bucket excavators and loaders. The purpose of the invention is to expand the operational capabilities by reducing the specific pressure on the soil. The machine has supports 1, which are made of elastic containers. The tanks are connected to a pneumatic system, made up of annular pipes 11 and 12 fixed under the turntable and fixed to the machine frame, which have inlet 14 and outlet 18 valves respectively. The rods 15 and 19 of the valves 14 and 18 are connected by pressure rings 16 and 20. Hydropushers 21 and 22 are fixed on the turntable. When the support 1 is in operation, the hydraulic cylinders 7 are lowered to the ground. The hydropusher 21 is then activated, the inlet valves 14 open and the compressed air flows into the tanks which are the supports. To move the machine, compressed air is vented from the tanks, the supports 1 are raised by hydraulic cylinders 7 and the machine moves to a new position. Then the cycle is repeated. 9 il. fc
