Quick positioning device for cast-in-situ bored pile reinforcement cage

The utility model provides a rapid positioning device for a cast-in-situ bored pile reinforcement cage. The rapid positioning device comprises a supporting mechanism, a telescopic mechanism arranged on the supporting mechanism in an inverted mode and a positioning mechanism assembled at the end of the telescopic mechanism. A clamping mechanism used for positioning the circle center of a drill hole is arranged on the supporting mechanism in a relative sliding mode. The positioning mechanism vertically extends to a set position along the circle center of the drill hole, and reinforcement cage position adjusting pieces capable of synchronously stretching out and drawing back are arranged on the positioning mechanism in a crossed mode. According to the description, the circle center of a drilled hole is positioned through the clamping mechanism on the supporting device, the positioning mechanism extends into the reinforcement cage under the action of the telescopic mechanism, the center position of the reinforcem
