Old pile dismantling device for pile foundation underpinning construction
The invention discloses an old pile dismantling device for pile foundation underpinning construction, and relates to the technical field of pile foundation underpinning construction, and the old pile dismantling device is characterized by comprising a main frame body, and the main frame body is provided with a hanging ring used for tying a steel wire rope and a balancing weight; two groups of cutting mechanisms capable of synchronously and relatively moving and a lifting mechanism for controlling the cutting mechanisms to lift are symmetrically arranged on one side, opposite to the balancing weight, of the main frame body; after the two sets of cutting mechanisms are close to each other and move by a specified distance, the lifting mechanism lifts the cutting mechanisms. According to the device, the lifting mechanism is controlled to lift the cutting mechanism after an old pile foundation is cut to a certain degree through hoisting of a crane and cooperation of the cutting mechanism and the lifting mechanism, then a pile body is snapped, meanwhile, the cutting mechanism is used for bearing the pile body, and therefore the pile body can be directly hoisted to the ground, and the working efficiency is improved.
本发明公开了一种桩基托换施工用旧桩拆除装置，涉及桩基托换施工技术领域，其技术方案要点是包括主架体，所述主架体上设置有用于系扣钢丝绳的吊环以及配重块；所述主架体相对配重块的一侧对称设置有两组可同步相对移动的切割机构以及用于控制切割机构升降的升降机构；两组切割机构在相互靠近移动指定距离后，升降机构对切割机构进行抬升。本装置通过吊车吊接使用，并利用切割机构与升降机构的配合，使其在对旧桩基切割至一定程度后控制升降机构对切割机构进行抬升，进而将桩体拉断，同时利用切割机构对桩体进行承托，从而可直接将其吊运至地面，提高了工作效率。
