Automatic Tensioning Machine For Multi-Size Prestressed Piles SolidWorks 3D Model

An automatic tensioning machine for adapting multi-size prestressed pipe piles, comprising a pipe pile mold assembly, a tensioning device, a lifting platform, a lifting platform horizontal displacement device, a pipe diameter detecting device, and a connecting and locking device for docking the tensioning device to a plate head tie rod, the tensioning device adjusting a height by a drive of the lifting platform, and the lifting platform adjusting the distance between the tensioning device and the pipe pile mold assembly by a drive of the lifting platform horizontal displacement device, the connecting and locking device comprising a conical connecting head fixedly connected to the plate head tie rod and a locking sleeve device fixedly connected to the tensioning rod, the locking sleeve device comprising a locking sleeve and a locking sleeve device fixedly connected to the tensioning rod. The connecting and locking device includes a conical connector fixedly connected to the tension rod of the plate head and a locking sleeve device fixedly connected to the tension rod of the tensioning device, the conical connector is necked down at the inner side to form a tensioning step, and the locking sleeve device includes a locking sleeve and a plurality of locking pins, which can be conveniently and accurately docked between the tensioning device and the tubular piling membrane assembly through the coordination of the locking pins and the tensioning step. The tensioning machine can be adapted to the tensioning of pipe piles of various specifications, and it can fully realize automation, liberate manual labor, and greatly improve the production efficiency. n The automatic tensioning machine adapted to multiple specifications of prestressed pipe piles, including n1 Pipe pile mold assembly n2 pipe diameter detection device n3 tensioning device n4 locking nut device n5 Locking sleeve device n6 Guide bar sensor assembly n7 Lift table n8 Horizontal displacement device of lifting table n Pre-tensioned prestressed concrete pipe pile precast concrete foundation pile, separate interpretation is; 1, “pre-tensioned prestressing” is in the pouring of concrete before the tensioning of prestressing tendons, and will be tensioned prestressing tendons temporarily anchored in the pedestal or steel mold, and then pouring the concrete, the concrete maintenance to reach not less than 75% of the value of the design strength of the concrete to ensure that the prestressing tendons and the concrete are sufficiently strong to ensure that the concrete is not less than the design strength value of the concrete, and to ensure that the prestressing tendons are sufficiently strong. To ensure that the prestressing tendons and concrete have sufficient bond, relax the prestressing tendons, with the help of concrete and prestressing tendons of the bond, the construction process of prestressing the concrete. 2. “Concrete Pipe Pile” A circular pipe-type pile with concrete as the structural strength.
