Description
виде двуплечего рычага рамной конструкции объемлющего мачту, с передней частью, оканчивающейс в плане треугольной режущей кромкой 15.the form of a two-shouldered lever frame frame enclosing the mast, with the front part, ending in a plan with a triangular cutting edge 15.
Устройство дл извлечени свай работает следующим образом. Опорна мачта 5 с убранной выдвижной частью 8 приводитс в вертикальное положение. Затем иож-рыхлитель 14 отвод т в рабочее положенпе, при котором режуща кромка 15 пожа 14 располагаетс ниже иодошвы мачты 5, после чего производ т откапывание верхней части извлекаемой сваи. Затем нолс-рыхлитель 14 откидываетс в транспортное положение и фиксируетс на мачте 5, котора опускаетс на грунт. Подвижна обойма 10 подъемного полиспаста с захватным устройством 11 опускаетс на оголовок сваи и закрепл етс на нем. Нат жением каната нодъемного полиспаста создаетс усилие, достаточное дл страгивани сваи. После извлечени сваи из грунта в пределах 1/5 ее длины включаетс полиспаст выдвижени внутренней части 8 мачты 5 и одновременно затормаживаетс подъемный полиспаст. При уменьщении сопротивлени грунта извлечеиию сван в процессе ее подъема включаетс подъемный полиспаст. Начина с этого момента , оба полиспаста работают как едина система. Благодар наличию в устройстве ножа-рыхлител цикл извлечени одной сваи сокращаетс на 3,36 мин, что соответствует увеличению производительности труда на 20%.The pile recovery apparatus operates as follows. The support mast 5 with the retractable part 8 retracted is brought into a vertical position. Then, the idler ripper 14 is retracted into the working position, in which the cutting edge 15 of the fire 14 is located below the iodosmay of the mast 5, after which the upper part of the extracted pile is excavated. Then, the knoll 14 ejects into the transport position and is fixed on the mast 5, which is lowered to the ground. The movable holder 10 of the lifting pulley with the gripping device 11 is lowered onto the pile head and secured to it. Tensioning the rope of the hoisting polyspast creates a force sufficient to break the pile. After the pile has been removed from the soil within 1/5 of its length, the chain hoist of the extension of the inner part 8 of the mast 5 is turned on and at the same time the hoist chain hoist is braked. When the soil resistance to extraction is reduced, the Svan, in the process of lifting it, turns on a lifting tackle. Starting from this point on, both of the tackles work as one system. Due to the presence of a knife-ripper in the device, the cycle of extracting one pile is reduced by 3.36 minutes, which corresponds to an increase in labor productivity by 20%.
