[0022] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Please refer to Figures 1 to 3 , the present invention provides a technical solution: a high-strain method foundation pile detection guiding device, including a frame 1, two symmetrically distributed guide rods 2 fixedly installed inside the frame 1. A guiding frame 3 is slidably sleeved on the two guide rods 2 together. A hammer head 4 is fixedly installed at the bottom of the guiding frame 3 through a plurality of first bolts 5. An installation opening 102 is provided at the top of the frame 1. A pressing block 8 is arranged inside the installation opening 102. The pressing block 8 is integrally T-shaped. The pressing block 8 is connected to the inner wall of the installation opening 102 through a second bolt 9. A top screw hole 103 is provided on the inner wall of the installation opening 102. A through hole is provided on the pressing block 8. The lower end of the second bolt 9 passes through the through hole and is threadedly inserted into the top screw hole 103. An insertion opening 801 is provided at the bottom of the pressing block 8. The upper end of the guide rod 2 is inserted into the insertion opening 801, so that the connection between the pressing block 8 and the guide rod 2 is tighter.

[0024] The guide rod 2 is used to linearly guide the guiding frame 3, and further to linearly guide the hammer head 4. When serious wear occurs between the guiding frame 3 and the guide rod 2, first loosen the plurality of first bolts 5 to separate the guiding frame 3 from the hammer head 4. Then, the pressing block 8 can be disassembled, and the guiding frame 3 can be separated from the two guide rods 2 to replace the guiding frame 3 to ensure normal use. The localized replacement method effectively saves economic costs.

[0025] Furthermore, a bottom screw hole 101 is provided at a position near the bottom of the frame 1. A stud 7 is fixedly connected to the lower end of the guide rod 2. The lower end of the stud 7 is threadedly inserted into the bottom screw hole 101.

[0026] When it is necessary to separate the guide rod 2 from the frame 1, turn the guide rod 2 to remove the stud 7 at the lower end of the guide rod 2 from the bottom screw hole 101 to achieve the disassembly purpose. At this time, the guide rod 2 can be replaced.

[0027] The guide rod 2 is of a cylindrical structure and is vertically distributed. Corresponding guiding openings are provided on the guiding frame 3. This structure can effectively reduce the friction with the guiding frame 3 and improve the service life.

[0028] A hook 6 is fixedly connected to the center position at the top of the hammer head 4. By connecting the hook 6 to an external traction component, the hammer head 4 is lifted to a certain height and then released. After releasing the hammer head 4, due to the action of gravity, the hammer head 4 will fall from a high place and contact the foundation pile to generate an impact force.

[0029] On both sides of the frame 1, side brackets 10 are fixedly connected. The bottom of the side brackets 10 is flush with the bottom of the frame 1. The provision of the side brackets 10 can provide additional support to prevent the frame 1 from tilting or shaking during use, thereby improving the stability and safety of the device. A strip-shaped opening is provided on the side brackets 10, and fasteners can also be passed through the strip-shaped opening to connect the side brackets 10 to other external components.

[0030] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
