DETAILED DESCRIPTION

[0010] Implementation example Figures 1 to 5As shown, the mobile assembled pile head breaking device of the present invention includes a cutting disc 1, a vertical base plate 2, a moving frame 3, a rotating column 4, a square plug rod 5, a driven gear 6, a driving gear 7, a driving motor 8, a first electric push rod 9, a limiting frame 11, a limiting slider 12, a positioning column 13, a screw 14, a pile head clamp 15 and a second electric push rod 16. The first electric push rod 9 is centrally arranged on the vertical base plate 2, the moving frame 3 is arranged on the rod end of the first electric push rod 9, the rotating column 4 is arranged on the front part of the moving frame 3 through a bearing 41, the rotating column 4 is axially provided with a square through groove 42, the square plug rod 5 is arranged in the square through groove 42, the cutting disc 1 is arranged at the bottom end of the square plug rod 5, the driven gear 6 is arranged on the outer ring of the rotating column 4, the driving motor 8 is arranged at the rear part of the moving frame 3 through a bracket 81, and the The driving gear 7 is arranged on the rotating shaft of the driving motor 8, and the driving gear 7 is meshed with the driven gear 6. The side wall of the rotating column 4 passes through the square plug rod 5 and is provided with a positioning groove 51. The limiting frame 11 is arranged on the side wall of the rotating column 4 and is connected to the positioning groove 51. The limiting slider 12 is arranged in the inner cavity of the limiting frame 11. The positioning column 13 is centrally arranged on the limiting slider 12 and is located in the positioning groove 51. The positioning column 13 is axially provided with a screw hole 131. The screw rod 14 penetrates the limiting frame 11 and the front end is screwed on the screw hole 131 of the positioning column 13. The pile head hoop 15 is respectively arranged on the upper and lower parts of the vertical substrate 2, and a partition 151 is arranged in the pile head hoop 15. The second electric push rod 16 is arranged on the partition 151, and the rod end is provided with an arc-shaped clamping plate 152 for clamping the pile head 10.

[0011] Preferably, the moving frame 3 further includes a guide rod 31 spaced apart at the rear end of the moving frame 3, and the vertical base plate 2 is provided with guide holes 21 on both sides of the first electric push rod 9, respectively, and the guide rod 31 is inserted into the guide hole 21. The guide rod makes it smoother for the first electric push rod to drive the moving frame, avoids jamming, and improves the stability of the moving frame when moving.

[0012] Preferably, the inner wall of the limit frame 11 is provided with a slide groove 111, and the limit slider 12 slides along the slide groove 111 in the inner cavity of the limit frame 11. The slide groove allows the limit slider to slide smoothly on the limit frame, thereby driving the positioning column to extend and retract in the positioning groove, ensuring the rapid disassembly and replacement of the cutting disc.

[0013] Preferably, the screw rod 14 penetrates into the limiting frame 11 through a bearing 141, and a nut 142 is provided on the outside of the limiting frame 11. The screw rod can be rotated conveniently by twisting the nut, thereby improving the efficiency of disassembly and replacement of the cutting blade.

[0014] When the pile head is broken and cut, first put the pile head clamps on the upper and lower parts of the vertical base plate into the pile head, start the second electric push rod to push the arc clamping plate against the pile head, so that the device is reliably fixed to the pile head. Then start the drive motor, which drives the rotating column and the square plug rod to rotate through the driving gear and the driven gear, so that the cutting disc rotates, and the first electric push rod pushes the moving frame to move the rotating cutting disc toward the pile head, so that the cutting disc performs the removal operation of the pile head on the pile foundation. When the cutting disc needs to be disassembled and replaced during the cutting process or later, the screw rod is rotated backward by turning the nut, thereby driving the positioning column to exit the positioning slot of the square plug rod and releasing the connection between the rotating column and the square plug rod. At this time, the square plug rod slides out of the square through slot of the rotating column, and the cutting disc can be quickly disassembled. When installing, insert the square plug rod connected to the cutting disc into the square through slot of the rotating column, align the positioning slot and reverse the nut, so that the screw rod drives the positioning column to advance into the positioning slot of the square plug rod, and re-lock the connection between the rotating column and the square plug rod to complete the installation of the cutting disc.

[0015] The device is fixed to the pile head by a pile head clamp, which ensures the stability of the device during the cutting operation and avoids damage to the cutting disc due to shaking; at the same time, in view of the frequent replacement of the cutting disc, the device sets a limit frame, a limit slider, a positioning column and corresponding locking and unlocking structures of the screw rod, so that the replacement operation of the cutting disc is faster and more convenient, and the operation is easy, which improves the efficiency of the pile head breaking operation and reduces the construction cost.
