[0059] With reference to Figure 5 and Figure 6 The number of the positioning plug rods 33 is two, the sleeve 341, the butt joint spring 342, the positioning plug rod 33 and the detection module 343 are one-to-one correspondingly arranged, the sleeve 341 is sleeved on the outside of the positioning plug rod 33, the butt joint spring 342 is welded between the inner end wall of the sleeve 341 and the end wall of the positioning plug rod 33, the extension direction of the butt joint spring 342 is parallel to the length direction of the positioning plug rod 33, and each end wall of each sleeve 341 is also vertically welded with an extension tube, the two extension tubes are threadedly sleeved with a bidirectional screw rod 1431, each end of the bidirectional screw rod 1431 corresponds to an extension tube, the bidirectional screw rod 1431 is rotationally connected in the cover plate 311, and the cover plate 311 is embedded with a motor for driving the bidirectional screw rod 1431 to rotate, the rotation of the bidirectional screw rod 1431 can be controlled according to the outer diameter of the steel pipe pile 4, so as to adjust the distance between the two positioning plug rods 33, so that the positioning plug rod 33 can be inserted into the lifting hole 41 of the steel pipe pile 4.

[0060] With reference to Figure 5 and Figure 6 The detection module 343 can be a distance measuring sensor for detecting the distance between the end wall of the positioning plug rod 33 close to the sleeve 341 and the inner end wall of the sleeve 341, i.e. the length of the butt joint spring 342, the detection module 343 is electrically connected to the controller, and the rotating piece 345 is controlled by the controller, and the controller can be a PLC controller, the detection data is transmitted to the controller by the detection module 343, the controller compares the detection data with the pre-stored data, and the pre-stored data is the length of the butt joint spring 342 when the butt joint spring 342 is not deformed.

If the detection data of the detection module 343 is equal to the pre-stored length of the abutting spring 342 during the rotation of the positioning rod 33, it means that the positioning rod 33 is inserted into the lifting hole 41 during the rotation. At this time, the controller will control the rotating part 345 to stop rotating, so as to realize the automatic positioning and insertion of the positioning rod 33 and the lifting hole 41.
