[0033] Working principle:

[0034] When the device is in use, the right end of the mobile frame 1 is first lifted by the handle 22, and pushed or pulled to the construction position on the temporary floating bridge, and then the right end of the mobile frame 1 is lowered until the grappling teeth 3 touch the ground, and then the drive box 5 is moved to the right part of the mobile frame 1, and the moving seat 4 at the bottom of the drive box 5 is fixed by the bolt 21, so that the center of gravity is shifted to the grappling teeth 3, the gripping force of the grappling teeth 3 is increased, and the stability of the device is improved; then the end of the diamond rope 9 away from the driving main wheel 6 is sleeved on the outside of the bridge pier (such as Figure 3 As shown), then, start the driving box 5, the driving box 5 drives the driving main wheel 6 to rotate counterclockwise, and the driving main wheel 6 drives the diamond rope 9 to rotate, so that the diamond rope 9 cuts the bridge pier. When just cutting, observe the shaking of the diamond rope 9. If the shaking is more obvious at the beginning, slide the counterweight 17 to the right to increase the downward pressure of the swing rod 16 on the lifting rod 13, so that the diamond rope 9 is more tightened, until the shaking is reduced to the minimum amplitude, and then fix the counterweight 17 by tightening the fastening button 18. As the cutting proceeds, the cutting part is closer and closer to the driving main wheel 6, and the diamond rope 9 begins to have a tendency to relax. At this time, the lifting rod 13 will slide down under the gravity of the swing rod 16 and the counterweight 17, so that the lifting wheel 12 moves downward, thereby tightening the diamond rope 9, and the swing rod 16 and the counterweight 17 can maintain a stable downward pressure on the lifting wheel 12, so that the diamond rope 9 maintains a stable tension, thereby ensuring that the diamond rope 9 maintains a stable cutting effect on the bridge pier.
