Description
Изобретение относитс к строительству и, в частности, к навесному оборудо ванию к стреловым кранам йл извлечени свай и вл етс усовершенствованием известного навесного оборудовани .The invention relates to the construction and, in particular, to attachments to jib cranes for removing piles and is an improvement of the known attachments.
Известно навесное оборудование к стреловому крану по основному авт.св. № 580271, используемое дл извлечени свай, которое включает смонтированные на стреле крана на оси головные блоки и П-образную раму с рабочим органом вибрадионного типа, закрепленную на стреле крана посредством съемных хомутов, охватывающих ее стойки и шарнирно соединенных с осью головных блоков стрелы. П-образна рама св зана с поворотной частью крана через телескопическую распорку , котора со стойками рамы и с по воротной частью крана св зана посредством плоских шарниров. Шарнирное соединение съемных хомутов с осью головных блоков стрелы крана кинематически также представл ет собой плоский шарнир. Основные стойки рамы снабжены опорамиKnown attachments to the boom crane on the main auth.St. No. 580271, used for removing piles, which includes head blocks mounted on the crane boom on the axle and a U-shaped frame with a vibrating-type working element, mounted on the crane boom by means of removable clamps covering its uprights and pivotally connected to the axis of the boom head blocks. The U-shaped frame is connected to the rotating part of the crane through a telescopic strut, which with the frame legs and to the portal part of the crane is connected by means of flat hinges. The hinged connection of the detachable yokes with the axis of the head blocks of the boom of the crane is kinematically also a flat hinge. Main frame legs are supported
выполненными в виде гидроцилиндров, полости которых соединены маслопроводом.made in the form of hydraulic cylinders, the cavities of which are connected by the oil pipe.
В св зи с наличием шарниров П-образ на рама не может быть наклонена в полости свайного р да, поэтому при извлечении свай, наклоненных в полости свайного р да, требуемое дл извлечени таких свай усилие должно быть увеличено.Due to the presence of hinges, the U-image on the frame cannot be tilted in the cavity of the pile row, therefore when extracting the piles inclined in the cavity of the pile row, the force required to extract such piles must be increased.
Целью изобретени вл етс повышение эффективности извлечени свай, наклоненных в полости свайного р да.The aim of the invention is to increase the efficiency of recovery of piles inclined in the pile cavity.
11оставленна цель достигаетс тем, что съемные хомуты объединены траверсой , а их шарнирное соединение с осью головных блоков стрелы выполнено посредством смонтированного на оси головных блоков стрелы кронштейна и шарового шарнира , обойм;а которр.го жестко закреплена на траверсе.The goal is achieved by the fact that the removable clamps are combined with a cross bar, and their hinge connection with the axis of the boom head blocks is made by means of a bracket mounted on the axis of the head blocks of the boom and a ball joint, which are fixed to the cross beam.
