Description

Изобретение относится к возведению оснований и фундаментов, преимущественно к устройствам для отламывания концов железобетонных свай, возвышающихся над грунтом.The invention relates to the construction of bases and foundations, mainly to devices for breaking off the ends of reinforced concrete piles towering above the ground.

Известно устройство для отламывания оголовка предварительно напряженных железобетонных Свай, включающее установленный на рукояти экскаватора посредством приводного поворотного рычага рабочий орган в виде установленных один над другим вилообразных рычагов, одни концы которых соединены между собой шкворнем, а другие — силовым цилиндром, и П-образную вилку, один конец которой шарнирно соединен с поворотным приводным рычагом [1]·A device is known for breaking off the head of prestressed concrete piles, including a working body mounted on the handle of an excavator by means of a rotary drive lever in the form of forked levers mounted one above the other, one ends of which are connected by a kingpin, and the other by a power cylinder, and a U-shaped fork, one end of which is pivotally connected to a rotary drive lever [1] ·

Однако излом свай может происходить в любой плоскости между двумя опорами, что ведет к неодинаковой высоте отламывания оголовков свай и требует дополнительных затрат ручного труда для выравнивания всех свай под одну проектную отметку, а периферийное расположение шарнирного соединения П-образной вилки с поворотным рычагом относительно центра тяжести устройства затрудняет поворот его при наведении на сваю. Все это отрицательно влияет на производительность устройства. Известно устройство для отламывания оголовков железобетонных свай, включающее установленные один наД другим вило5 образные рычаги, одни концы которых соединены между собой шкворнем, а другие — силовым цилиндром, упоры, закрепленные посредством горизонтальных осей на вило. образных рычагах [2].However, kinks of piles can occur in any plane between two supports, which leads to uneven heights of breaking off the pile heads and requires additional manual labor to align all piles to the same design mark, and the peripheral location of the articulated joint of the U-shaped fork with the pivot arm relative to the center of gravity device makes it difficult to rotate it when you hover over the pile. All this negatively affects the performance of the device. A device is known for breaking off the heads of reinforced concrete piles, including fork-shaped levers mounted one on top of the other, one end of which is connected by a kingpin, and the other by a power cylinder, stops fixed by means of horizontal axes on the fork. shaped levers [2].

¹⁰ На нижнем_х вилообразном рычаге ус тановлены регулируемые клиновые ножи, расположенные на одной геометрической оси с осью шкворня, а на верхнем вилообразном рычаге установлен упор, служа15 щий для передачи усилия от силового цилиндра на сваю, создающего изгибающий момент относительно плоскости зажима. ¹⁰ On the lower _x -shaped lever, adjustable wedge knives are installed, located on the same geometric axis as the axis of the pin, and on the upper fork-shaped lever, an emphasis is used to transfer force from the power cylinder to the pile, creating a bending moment relative to the clamp plane.

Регулируемые клиновые ножи, опр£деляющие плоскость излома, расположены в нижнем рычаге, а упор, передающий уси²⁰ лие на сваю — в верхнем. Этим самым применение известного устройства ограничивается минимальной длиной оголовков свай, близкой к расстоянию между клиновыми ножами и упором, и обработка свай с указанной длиной оголовков требует дополнительных затрат ручного труда.Adjustable wedge knives that define the fracture plane are located in the lower lever, and the emphasis, which transfers the force of ²⁰ to the pile, is in the upper. Thus, the use of the known device is limited to the minimum length of the pile heads close to the distance between the wedge knives and the stop, and processing piles with the specified length of the heads requires additional manual labor.
