A three-legged mast hoisting device comprises base plates, supporting legs, two sets of reinforcing rods, a cross beam, a support lifting device and an upper lifting sliding device, each supporting leg is of a two-section structure, an adjusting device and two sets of reinforcing rods are installed between each two sections of supporting legs, the lower ends of the two sets of supporting legs are installed at the upper ends of the base plates respectively, and the cross beam is connected with the support lifting device. The lower end of each set of reinforcing force rod and the upper end of a set of hydraulic oil cylinder A are fixedly installed together, and the lower end of the hydraulic oil cylinder A is installed on the base plate. The lower portions of the front ends and the rear ends of the two cross beams are installed together with the upper ends of the two supporting legs and the upper ends of the reinforcing rods respectively, and the upper ends of the two cross beams are each provided with a limiting pipe. The upper lifting sliding device is inserted into the two supporting pipes, and the two support lifting devices are hooked to the lower ends of the two cross beams respectively. The device is very convenient to transport and mount, can be matched with light mechanical operation, greatly improves the hoisting efficiency, reduces the construction cost of the cast-in-place pile, can realize accurate positioning and stable and slow hole entering, and avoids secondary hole cleaning.

    三脚式桅杆吊装装置,包括垫板、支腿、加强力杆、横梁、支架升降装置和上部升降滑动装置,每只支腿为两段式结构,每只两段支腿之间安装有调整装置,两套加强力杆、两套支腿的下端分别安装在多只垫板的上端,每套加强力杆的下端和一套液压油缸A的上端固定安装在一起,液压油缸A的下端安装在垫板上;两只横梁的前后端下部分别和两套支腿及加强力杆的上端安装在一起,两只横梁的上端分别安装有一根限位管;上部升降滑动装置插接在两只支撑管内,两套支架升降装置分别钩挂在两只横梁的下端。本发明运输和安装均很方便,能配合轻型机械作业,极大提高了吊装效率,降低了灌注桩施工成本,能实现准确定位、平稳缓慢入孔,避免了进行二次清孔。
