[0019] In addition, the drawings are only schematic and are non-limiting. Identical reference signs refer to like or similar elements throughout the drawings and specification. It should be noted that the terminology used in the disclosure is not intended to limit the scope of the present application and should be interpreted broadly. The terminology specifically disclosed and defined herein should be interpreted in the same way as the terminology used in the art.

[0020] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an overly literal or overly formal sense unless expressly so defined herein.

[0021] In this embodiment, a pile head cutting device for construction is disclosed, Fig. 1 The entire cross-sectional structure of the pile head cutting device for construction is shown. Fig. 2 The planar structure of the pile head cutting device for construction is shown. Fig. 3 The cross-sectional structure of the rectangular frame is shown.

[0022] Please refer to Figs. 1 to 3 The pile head cutting device for construction comprises an annular frame, a track assembly, a cutting assembly and a dust suppression assembly arranged on the annular frame. The track assembly is fixed to the annular frame by bolts 24, providing a closed-loop motion path for the cutting assembly. The cutting assembly is connected to the track through double spherical pulleys, and a driving motor 26 drives a cutting saw blade 28 to perform circular cutting. The water supply pipe 23 of the dust suppression assembly is welded to the end of the support 20 of the cutting assembly, and the spray head 27 is aligned with the cutting point to provide water pressure through the pressure device 22 to suppress dust. The dust suppression assembly is rigidly connected to the cutting assembly to ensure that the spray head 27 always moves synchronously with the saw blade, thereby suppressing dust dispersion from the source.

[0023] Further, the annular frame is composed of at least three rectangular frame units welded together. Each rectangular frame unit includes three vertical rods, i.e. a first vertical rod 1, a second vertical rod 2 and a third vertical rod 3, and four horizontal rods, i.e. a first horizontal rod 4, a second horizontal rod 5, a third horizontal rod 6 and a fourth horizontal rod 7. All vertical rods are perpendicular to the ground and parallel to each other, and all horizontal rods are horizontally welded to the ends of the vertical rods and parallel to each other. Adjacent rectangular frame units are connected into an annular whole through at least four annular rods, i.e. a first annular rod 10, a second annular rod 11, a third annular rod 12 and a fourth annular rod 13. The first diagonal rod 8 and the second diagonal rod 9 are diagonally welded at the bottom of the frame to significantly enhance the torsional stiffness.

[0024] Further, the first adjusting screw 15 and the second adjusting screw 16 are arranged in the inner recesses of the first vertical rod 1 and the second vertical rod 2, and the ends of the adjusting screws are provided with adjusting nuts. By rotating the nuts, the extension amount of each vertical rod can be independently controlled to adapt to uneven ground and adjust the overall levelness of the frame. The third adjusting screw 17 is arranged in the recess of the first horizontal rod 4, and the end of the third adjusting screw 17 is provided with a jacking bolt 24. The entire device is fixed to the pile body 32 through the third adjusting screw 17 to ensure the cutting distance while avoiding displacement of the device. When the device is sleeved on the pile body 32, the screw is jacked against the pile body by tightening the bolt 24 to ensure uniform spacing and stable fixation between the device and the pile body 32.

[0025] Further, the track assembly includes two horizontal first annular tracks 30 and second annular tracks 31, and a vertical annular track, i.e. a third annular track 14. The first annular track 30 and the second annular track 31 are fixed to the fourth horizontal rod 7 of each rectangular frame unit by the bolt 24, and the third annular track 14 is fixed to the third vertical rod 3. The first annular track 30 and the second annular track 31 are used to bear the main weight of the cutting assembly and to guide the horizontal sliding of the cutting assembly, and the third annular track 14 is used to limit the vertical displacement of the cutting assembly. The fourth horizontal rod 7 extends beyond the annular frame to form an overhanging section, which serves as a lifting lug to facilitate transportation and provides additional support for the ends of the tracks.

[0026] Further, a recess is formed on one side of the annular frame, and a reinforcing frame 33 is welded to the top of the recess to fix the ends of the tracks and the annular rods. The reinforcing frame 33 is a I-shaped section steel, wherein the vertical direction of the I-shaped section steel is composed of two rod members. The ends of the recess are fixed as the end fixing members of the tracks through the reinforcing frame 33, and are rigidly connected with the first annular rod 10, the second annular rod 11, the third annular rod 12 and the fourth annular rod 13 to achieve overall stability. The width of the recess is greater than the diameter of the cutting saw blade 28 to ensure that the cutting saw blade 28 can be safely withdrawn after cutting is completed.

[0027] Furthermore, the cutting assembly includes a first double spherical pulley 18 and a second double spherical pulley 19 nested within a horizontal track, a single spherical pulley 29 nested within a third annular track 14, and a bracket 20 mounted on the first double spherical pulley 18 and the second double spherical pulley 19. The bracket 20 is L-shaped, and the pulleys are hinged to the L-shaped bracket 20 via bearings. A drive motor 26 is fixed to the bracket 20 via a detachable base 25, and a cutting saw blade 28 is mounted on its output shaft. When the handrail 21 welded to the bracket 20 is manually pushed, the spherical pulleys roll along the track, causing the cutting saw blade 28 to precisely cut along the circumference of the pile body 32.

[0028] Furthermore, in the dust suppression assembly, the water supply pipe 23 extends along the bracket 20, with the water inlet end connected to the pressure booster 22 and the end end fitted with a nozzle 27. The nozzle 27 sprays at an acute angle to the plane of rotation of the saw blade, directly covering the cutting dust point.

[0029] Furthermore, a first diagonal brace 8 and a second diagonal brace 9 are welded into each rectangular frame unit to form a triangular support structure, effectively dispersing the cutting vibration load. The welds between the diagonal braces and the horizontal and vertical braces are continuous and full, ensuring the structural integrity of the frame under dynamic loads.

[0030] During construction, the device is hoisted to position 32 on the pile body. The frame is leveled and adjusted to the ground slope by adjusting the first adjusting screw 15 and the second adjusting screw 16. The third adjusting screw 17 is tightened to ensure the device fits evenly against the pile body. The drive motor 26 is started to rotate the cutting saw blade 28, and the handrail 21 is manually and slowly pushed to move the cutting unit circumferentially along the track. Simultaneously, the pressurizer 22 is activated, and water mist is continuously sprayed from the nozzle 27 through the water supply pipe 23 to the cutting point. After completing one cut, the saw blade is returned to the recessed area, the device is disassembled, and the device is moved to the next pile position.

[0031] In summary, this device, through the coordination of an adjustable frame and a closed-loop track, eliminates cutting tilt caused by manual operation; the dual-track system constrains the cutting trajectory, ensuring the saw blade remains perpendicular to the pile body 32, guaranteeing the flatness of the cross-section; the dust suppression component and the cutting component are rigidly synchronized, suppressing dust generation instantly; the notch prevents the cutting saw blade 28 from jamming and improves pile replacement efficiency. Throughout the process, this invention uses the system's cutting mechanism to control the flatness of the cut surface, greatly reducing the uncertainties of human control, ensuring construction quality, and significantly reducing the construction difficulty coefficient, increasing construction safety, and maintaining levelness even on uneven ground. It is highly flexible, the system is stable and reliable, and standardized construction can be achieved. This greatly increases construction efficiency.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
