[0033] After the anchor rod body 11 is installed, the operation position needs to be installed, as shown in the figure Figure 1 -attached Figure 4 As shown in the figure, two groups of adjusting rods 12 are welded on the two sides of the bottom frame 1, the adjusting rod 12 is provided with a thread, the bottom frame 1 is provided with an operation plate 2, and the operation plate 2 is connected with the adjusting rod 12 by a nut, according to the construction site environment and the size of the pile to be installed, first, the lower nut is rotated to the corresponding position, then the installation hole on the operation plate 2 is aligned with the four adjusting rods 12, the bottom of the operation plate 2 is slid to the position where the fixed nut is contacted, then the upper fixed nut is tightened, so that the operation plate 2 is adjusted to the corresponding height position, the center of the operation plate 2 is provided with an arc-shaped slot 15 through which the pile passes, the arc-shaped slot 15 corresponds to the center position of the round hole 14, and the front end of the operation plate 2 is provided with a baffle 3. The bottom of the fixed plate 21 is connected to the pad 13, the fixed plate 21 is provided with two clamping blocks 29 at the bottom, and the two clamping blocks 29 are clamped with the bottom frame 1.

[0034] After the operation plate 2 is installed, two groups of hydraulic rods 4 are installed on the operation plate 2, the upper part of the hydraulic rod 4 is fixed on the operation plate 2, and the end of the hydraulic rod 4 penetrating through the operation plate 2 is connected with a clamping assembly 5, the back of the operation plate 2 is provided with a fixed plate 21, and a strip-shaped slot 23 is arranged on the fixed plate 21, the top of the hydraulic rod 4 is connected with a hydraulic pipe 22, one end of the two hydraulic pipes 22 penetrating through the strip-shaped slot 23 is connected with an input pipe 24, and one end of the input pipe 24 is connected with a hydraulic control box 25.

[0035] When the hydraulic rod 4 moves downward, the wedge-shaped clamp 61 and the wedge-shaped groove 51 cooperate with each other, so that the upper part of the pile is clamped by the clamping assembly 5 and the lower part is clamped by the wedge-shaped clamp 61. When the pile is further clamped, the clamping assembly 5 disengages and the wedge-shaped clamp 61 remains on the outside of the pile, which helps to limit the lower part of the pile and avoid the displacement caused by the upper pile pressing on the lower pile.

[0036] For the clamping assembly 5 clamped outside the pile body, as shown in Appendix 6 Figure 8 As shown, the device includes a fixing block 52 installed at the output end of the hydraulic rod 4. Support plates 53 are provided on both sides of the fixing block 52. The support plates 53 are made of elastic material, and a clamping plate 54 connects the two support plates 53. Wedge-shaped grooves 51 are formed at both ends of the clamping plate 54. An installation groove 55 is installed on the back of the fixing block 52, and a hole is formed on the fixing block 52. An electric actuator 56 is installed at the installation groove 55, and the output end of the electric actuator 56 passes through the hole.

Protective blocks 59 are provided on both sides of the deformation transition groove 58, and the protective blocks 59 are installed on the clamping plate 54.

[0037] After the lifting equipment lifts the pile, the baffle 3 is opened, and the pile is placed in the center of the arc-shaped groove 15. At this time, the electric actuator 56 is pulled back, so that the clamping plate 54 is attached to the surface of the pile. The two symmetrical clamping plates 54 clamp the pile. Then, the hydraulic control box 25 controls and adjusts the output of hydraulic oil, thereby controlling the lifting and lowering process of the hydraulic rod 4. After the pile is pressed into the hole in the soil, the lifting equipment lifts a new pile. When the hydraulic rod 4 drives the clamping plate 54 to press the clamped pile into the corresponding position in the hole, the wedge-shaped clamping block 61 just cooperates with the wedge-shaped groove 51, thereby pushing the wedge-shaped clamping block 61 outward a certain distance.

When the wedge-shaped clamping block 61 is pushed and adjusted, and when the clamping plate 54 needs to be separated from the pile body and clamp the newly hoisted pile body, at this time, the clamping plate 54 is loosened along the clamping position of the pile body by pushing forward through the electric push rod 56. Since the deformed transition groove 58 is arranged in the middle section of the clamping plate 54, when the clamping plate 54 is opened outward from the bent state, the middle part is prevented from pushing the pile body. When the new pile body is clamped and conveyed to the lower pile body position through the hydraulic rod 4, the welding equipment is used to weld the splicing surfaces of the two pile bodies, so that the two pile bodies form an integral whole. Since the wedge-shaped clamping block 61 is pushed into the surface of the pile body by the wedge-shaped groove 51 on the clamping plate 54, after the wedge-shaped clamping block 61 is determined in position, the same clamping position is maintained, which is beneficial to the limiting during the subsequent pile welding.
