The invention relates to a lifting appliance suitable for bored pile reinforcement cages with different diameters. The lifting appliance comprises a cross beam, a sliding device, a lifting lug, a shackle, a steel wire rope, a limiting device and a stiffening plate. The cross beam is formed by welding H-shaped steel into a whole; the sliding device is hung on a lower flange plate of the cross beam through a bearing and slides; the lifting lugs are fixed with the cross beam through welding; the shackle connects and fixes the steel wire rope and the lifting lug; the upper-end steel wire rope is used for connecting hoisting equipment with the cross beam, and the lower-end steel wire rope is used for connecting the sliding device with the drilled pile reinforcement cage; the limiting device is mounted at the end part of the cross beam to prevent the sliding device from derailing; the stiffening plates are arranged on the upper flange and the lower flange of the cross beam and used for enhancing the stability of the double-section steel. The lifting appliance can be suitable for lifting reinforcement cages with different pile diameters, and can be reused; extra operation is not needed, the sliding device can automatically slide under the action of horizontal force until the steel wire rope is vertical, and operation is simple; the invention is formed by welding common profile steel and steel plates, has a simple structure and saves cost.

    本发明涉及一种适用于不同直径的钻孔桩钢筋笼吊具,包括十字梁、滑动装置、吊耳、卸扣、钢丝绳、限位装置、加劲板。十字梁由H型钢焊接为整体;滑动装置通过轴承挂在十字梁下翼缘板,并实行滑动;吊耳通过焊接与十字梁固定;卸扣将钢丝绳和吊耳连接固定;上端钢丝绳用于连接起重设备与十字梁,下端钢丝绳用于连接滑动装置与钻孔桩钢筋笼;限位装置安装在十字梁端部,防止滑动装置脱轨;加劲板设置在十字梁的上下翼缘,用于增强双拼型钢的稳定性。本吊具可适用于不同桩径的钢筋笼吊装,并实现重复利用;无需额外操作,滑动装置在水平力作用下可实现自动滑动,直至钢丝绳垂直,操作简单;由常见的型钢和钢板焊接而成,结构简单,节省成本。
