Lifting device for preventing deformation of reinforcement cage for slurry protection wall cast-in-situ bored pile construction
The invention relates to the technical field of slurry wall protection cast-in-situ bored pile construction, in particular to a hoisting device for preventing deformation of a reinforcement cage for slurry wall protection cast-in-situ bored pile construction. Comprising a moving platform, the moving platform is connected with a guide rail through an L-shaped support and a first rotating shaft, the guide rail is provided with an overturning mechanism used for being fixedly connected with a reinforcement cage, a top plate is provided with a clamping mechanism used for fastening a traction rope, and a second fixing block is provided with a first adjusting mechanism used for controlling the distance between symmetrical first limiting blocks. The T-shaped bearing rail is provided with a second adjusting mechanism used for controlling the distance between the first limiting block and the top plate. The reinforcement cage is subjected to multi-point radial limiting, local deformation of the reinforcement cage caused by uneven stress when the reinforcement cage is turned over is avoided, the reinforcement cage is subjected to radial limiting through the positioning rotating rollers, the reinforcement cage is prevented from colliding with the hole wall of a drilled hole in the hoisting and placing process, and the supporting mechanism limits the reinforcement cage in the axial direction and the radial direction, so that the hoisting efficiency is improved. And the steel reinforcement cage in the drill hole is prevented from deviating and colliding with the wall of the drill hole.
本发明涉及泥浆护壁钻孔灌注桩施工技术领域，尤其涉及一种泥浆护壁钻孔灌注桩施工用防钢筋笼形变的吊放装置。包括有移动平台，移动平台通过L形支架、第一转轴连接有导轨，导轨设置有用于固接钢筋笼的翻转机构，顶板设置有用于紧固牵引绳的夹紧机构，第二固定块设置有用于控制对称第一限位块之间距离的第一调节机构，T形承重轨设置有用于控制第一限位块和顶板之间距离的第二调节机构。通过对钢筋笼进行多点径向限位，避免在翻转钢筋笼时因受力不均匀引起的钢筋笼局部变形，定位转辊对钢筋笼进行径向限位，避免钢筋笼在吊放过程中与钻孔孔壁发生碰撞，支撑机构对钢筋笼的轴向及径向的限位，防止钻孔内钢筋笼的位置发生偏移与钻孔壁发生碰撞。
