The steel trestle has openings for installing the hydraulic guide frame. The hydraulic guide frame includes a hydraulic jack, a support base, a first guide frame, a second guide frame, a connecting ring, and a connecting rod. The support base has a plurality of slide rails evenly distributed in a circular array. The bottom of the hydraulic jack has a slider, which is mounted on the slide rails. The support base is installed at the opening of the steel trestle. The connecting ring is located below the support base, and the second guide frame is located below the connecting ring. The connecting rod connects the connecting ring and the second guide frame.

[0006] Preferably, both the inner walls of the first guide frame and the second guide frame are provided with ball bearings.

[0007] Preferably, the top of the hydraulic jack is equipped with a horizontal support rod; the other end of the horizontal support rod is connected to an arc-shaped clamping plate; and the arc-shaped clamping plate is provided with an anti-slip pad.

[0008] Preferably, the connecting ring is welded to the bottom of the support base; a plurality of connecting rods arranged in a circumferential array are welded at one end to the bottom of the connecting ring and at the other end to the second guide frame.

[0009] The beneficial effects of this utility model are:

[0010] 1) This utility model uses a clamping structure constructed by a hydraulic jack, an arc-shaped clamping plate, and a slide rail to stably clamp and lower steel pipe piles, reducing swaying and offset during hoisting and lowering, and improving construction accuracy.

[0011] 2) The double-layer guide frame constructed by the first guide frame and the second guide frame of this utility model can efficiently guide the steel pipe pile to accurately enter the hole, improve the positioning accuracy, and thus improve the construction quality and efficiency of the entire project.

[0012] 3) This utility model integrates clamping and positioning functions into the same device. Through the clamping and lowering of the hydraulic jack and the positioning of the guide frame, the precise driving of steel pipe piles is achieved. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to embodiments. The description of the embodiments below is only for the purpose of helping to understand the present invention. It should be noted that, for those skilled in the art, several modifications can be made to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0019] As one example, such as Figures 1 to 4As shown: This steel pipe pile clamping and positioning structure includes a steel pipe pile 1, a hydraulic guide frame 2, and a steel trestle 3. The steel trestle 3 has openings for installing the hydraulic guide frame 2. The clamping and positioning functions are integrated into the same device. Through the clamping and lowering of the hydraulic jack 3 and the positioning of the guide frame, precise driving of the steel pipe pile 1 is achieved. The hydraulic guide frame 2 includes a hydraulic jack 4, a support base 6, a first guide frame 9, a second guide frame 10, a connecting ring 7, and a connecting rod 8. Ball bearings 11 are provided on the inner walls of both the first guide frame 9 and the second guide frame 10. The support base 6 has six slide rails 15 evenly distributed in a circular array. The bottom of the hydraulic jack 4 has a slider 5, which is mounted on the slide rails 15. A transverse support rod 13 is installed on the top of the hydraulic jack 4. The other end of the transverse support rod 13 is connected to an arc-shaped clamping plate 12. An anti-slip pad 14 is provided on the arc-shaped clamping plate 12. This embodiment utilizes a clamping structure constructed with a hydraulic jack 4, an arc-shaped clamping plate 12, and a slide rail 15 to stably clamp the steel pipe pile 1 and lower it, reducing swaying and offset during hoisting and lowering, and improving construction accuracy. A support base 6 is installed at the opening of the steel trestle 3; a connecting ring 7 is located below the support base 6, and a second guide frame 10 is located below the connecting ring 7. Connecting rods 8 connect the connecting ring 7 and the second guide frame 10. This embodiment, with its double-layered guide frame constructed from the first and second guide frames, efficiently guides the steel pipe pile accurately into the opening, improving positioning accuracy and thus enhancing the overall construction quality and efficiency. The connecting ring 7 is welded to the bottom of the support base 6; six connecting rods 8, arranged in a circular array, are welded at one end to the bottom of the connecting ring 7 and at the other end to the second guide frame 10.

[0020] The specific steps for installing the hydraulic guide frame and lowering the steel pipe piles are as follows:

[0021] S1. An opening is set on the steel trestle bridge 3 for lowering the steel pipe pile 1.

[0022] S2. Install the connecting ring 7 at the bottom of the support base 6, connect the connecting rod 8 to the connecting ring 7 and the second guide frame 10, and install the prepared guide frame at the opening of the steel trestle 3 and fix it.

[0023] S3. Install the hydraulic jack 4 with the slider 5 at the bottom onto the slide rail 15 of the support base 6.

[0024] S4. Use a crawler crane to lift the steel pipe pile 1 and lower it onto the hydraulic guide frame 2, ensuring its verticality.

[0025] S5. Move the hydraulic jack 4 forward after lifting so that the arc-shaped clamping plate 12 is close to the pipe wall, control the hydraulic jack 4 to descend, and the steel pipe pile 1 will descend accordingly.

[0026] S6. Then control the adjacent hydraulic jack 4 to lift and move forward to clamp the steel pipe pile 1. Then control the lowered hydraulic jack 4 to move backward and lift. Repeat the clamping, lowering, lifting and moving steps to make the steel pipe pile 1 steadily lower to the designated position, and then drive the steel pipe pile 1 into the soil.
