[0030] In a preferred embodiment, the positioning notch 407 on the upward side of the positioning guide plate 405 is provided with a rounded corner.

[0031] In the preferred embodiment, a gap is provided between the bottom of the positioning guide plate 405 and the chassis 302 , and the gap is used for installing a sleeve when the upper reinforcement cage 2 and the lower reinforcement cage 2 are docked.

[0032] In the preferred embodiment, the limiting assembly 5 includes a limiting push rod 501 , a limiting rod 502 is provided at the front end of the limiting push rod 501 , the limiting push rod 501 is used to control the extension and contraction of the limiting rod 502 , and the limiting rod 502 is used to limit the sinking of the steel cage 2 .

[0033] In the preferred embodiment, the fixing assembly 6 includes a fixing bracket 601 , a magnetic joint 602 is provided on one side of the fixing bracket 601 , a positioning arc groove 603 is provided on the side of the magnetic joint 602 close to the pipe pile 1 , and the positioning arc groove 603 is arranged concentrically with the outer circle of the pipe pile 1 .

[0034] In a preferred embodiment, the positioning arc groove 603 and the closed positioning notch 407 on the positioning guide plate 405 are coaxially arranged.

[0035] The specific working method of a pile foundation reinforcement cage installation positioning device is as follows: first, the positioning device is moved to the pipe pile 1, and the magnetic attraction joint 602 is brought close to the pipe pile 1 so that the positioning arc groove 603 is in contact with the outer wall of the pipe pile 1. The switch of the magnetic attraction joint 602 is turned to make the magnetic attraction joint 602 attract the pipe pile 1. Then, the cutting column 303 is hammered into the soil to complete the fixing of the positioning device. Then, the positioning push rod 404 is remotely controlled to open the positioning guide plate 405 to both sides.

[0036] Then, the steel cage 2 is hoisted into the positioning slot 407 in the middle of the positioning guide plate 405 by the crane, and the positioning push rod 404 is tightened by remote control to close the positioning guide plate 405. After the positioning guide plate 405 is closed, its positioning slot 407 is concentric with the pipe pile 1 below. At this time, it is only necessary to slowly lower the steel cage 2. When it is lowered to the specified height, the limit push rod 501 is remotely controlled to extend the limit rod 502. The limit rod 502 can clamp the steel cage 2 to prevent the steel cage 2 from continuing to fall. If it is a multi-section steel cage 2, after the limit rod 502 is fixed, the crane continues to hoist the subsequent steel cage 2, and continues to repeat the positioning. Then, the docking device is manually installed at the interface of the two sections of the steel cage 2 to complete the docking. The subsequent limit rod 502 releases the steel cage 2 that has been docked. When the subsequent steel cage 2 drops to the specified height, the limit rod 502 continues to clamp the steel cage 2 to complete the subsequent docking.
