Abstract
Изобретение относитс к строительству и может быть использовано при производстве свайных работ. Цель изобретени - повышение качества отделени оголовков свай. Устройство содержит верхний 3 и нижний 4 захваты, соединенные между собой опорно-поворотным кругом, зажимные рычаги 5 и 6, фиксирующие устройство на свае, а также силовые гидроцилиндры 7, обеспечивающие резку арматуры и скручивание сваи, кинематически св занные с внешней 1 и внутренней 2 обоймами круга. Резка арматуры осуществл етс ножами 12,13, установленными во фланце 11, соединенном с внутренней обоймой 2 круга, и перемещаемыми посредством клиньев 14,15, соединенных с внешней обоймой 2 при относительном вращении обойм, посредством цилиндров 7, зажимными рычагами 5 и 6. Устройство навешиваетс на сваю краном или экскаватором за петли 8. 7 ил.The invention relates to construction and can be used in the manufacture of piling. The purpose of the invention is to improve the quality of the separation of pile tips. The device contains the upper 3 and lower 4 clamps, interconnected by a turntable, clamping levers 5 and 6, fixing the device on the pile, as well as power hydraulic cylinders 7, providing cutting of reinforcement and twisting of the pile, kinematically connected with external 1 and internal 2 circle holders. The rebar is cut by knives 12,13 installed in a flange 11 connected to the inner race 2 circles and moved by means of wedges 14,15 connected to the outer race 2 with relative rotation of the sleeves, by means of cylinders 7, clamping levers 5 and 6. Device is mounted on a pile with a crane or an excavator behind hinges 8. 7 Il.
