[0046] Example 2

[0047] Further explanation in conjunction with Example 1, such as Figures 3-6 As shown in Figures 8 and 10, this embodiment also includes a pile foundation locking mechanism 23 located at the bottom of the telescopic insert section 211, which is used to further enhance the connection stability with the pile foundation 1.

[0048] Furthermore, the pile foundation locking mechanism 23 includes a base plate 230 disposed at the bottom end of the telescopic insert section 211. The base plate 230 closes the opening at the bottom of the telescopic insert section 211. The base plate 230 is provided with a plurality of first through slots 231. In this embodiment, the number of first through slots 231 is six. Each first through slot 231 has a straight guide slot 232 at its bottom. The outer end of the straight guide slot 232 is open, and the top is provided with a second through slot 234 corresponding to the through slot 231. An L-shaped locking frame 235 is slidably disposed in the second through slot 234. The L-shaped locking frame 235 is specifically inverted L-shaped. Limiting slots 238 are provided on the opposite inner wall surfaces of the second through slot 234. Limiting blocks 236 are provided on both sides of the top front end of the L-shaped locking frame 235.

[0049] Meanwhile, a rotary bearing 239 is provided on the top of the base plate 230, and a turntable 2310 is rotatably mounted in the rotary bearing 239. The turntable 2310 is provided with a plurality of moving drive slots 2311 corresponding to the first through slot 231.

Inside the telescopic insert section 211, there is a support base 2313 located above the turntable 2310. A second drive device 2314 is provided on the top of the support base 2313. The output shaft of the second drive device 2314 passes through the support base 2313 and is equipped with a drive gear 2315. The drive gear 2315 meshes with the internal gear ring 2312, so that the drive gear 2315 can drive the internal gear ring 2312 and the turntable 2310 to rotate through the drive of the second drive device 2314.

[0050] In addition, the top of the L-shaped locking frame 235 is provided with a second through rod 237 passing through the corresponding second through slot 234, the first through slot 231 and the movement driving slot 2311. Through the connection relationship between the second through rod 237 and the movement driving slot 2311, and the connection relationship between the second through rod 237 and the straight guide slot 232, the L-shaped locking frame 235 can move outward or inward when the rotating disc 2310 is reversed, so that when facing the hollow pile, the L-shaped locking frame 235 can be expanded outward to abut against the inner wall of the hollow pile, thereby achieving the clamping effect.

[0051] It should be noted that before the telescopic plug core section 211 is inserted into the hollow pile, the L-shaped locking frame 235 needs to be moved inward to the outer diameter range of the telescopic plug core section 211.

[0052] Further, the number of L-shaped locking frames 235 are positioned corresponding to the sliding grooves 2102. When the telescopic plug core section 211 is located in the fixed plug sleeve section 210, the L-shaped locking frame 235 can be completely moved into the corresponding sliding groove 2102, so that when facing the solid pile, the L-shaped locking frame 235 can be moved into the corresponding sliding groove 2102 before the solid pile is inserted into the fixed plug sleeve section 210. After the solid pile is inserted into the fixed plug sleeve section 210, the L-shaped locking frame 235 is moved inward to achieve clamping and fixing of the solid pile.

[0053] In this way, the installation strength can be further improved, and the size precision requirement between the pile foundation butt joint part 21 and the pile foundation 1 can be appropriately reduced, and the compensation is achieved through the L-shaped locking frame 235.
