[0020] like Figure 3As shown: two groups of second rails 2 are provided on both sides of the middle of the first rail 1, perpendicular to the first rail 1, and the two second rails 2 are arranged in parallel as a group. A group of clamping devices 5 are slidably provided on each second rail 2, and the clamping device 5 includes a clamping arm slide 501, a clamping arm 502, a hydraulic rod slide 503 and a hydraulic rod 504. A hydraulic rod slide 503 is movably provided on the second rail 2, and a clamping arm slide 501 is movably provided on the side of the second rail 2 where the hydraulic rod slide 503 is adjacent to the first rail 1. The bottom end of the clamping arm 502 is hinged to the clamping arm slide 501, the fixed end of the hydraulic rod 504 is hinged to the hydraulic rod slide 503, and the telescopic end of the hydraulic rod 504 is hinged to the middle part of the clamping arm 502.

[0021] like Figure 4 , Figure 5As shown: a cutting device 6 is provided on both sides of the first track 1 and reciprocates along the second track 2. The cutting device 6 includes a rope saw machine 601, a tensioning guide wheel 602 and a tensioning slide 603. The rope saw machine 601 is slidably provided on the two second tracks 2 on one side. The structure of the rope saw machine 601 is the same as that of the existing rope saw machine 601. Its driving wheel disc is located in the middle of the two second tracks 2 on one side. A tensioning slide 603 is slidably provided on the two second tracks 2 on the other side. A tensioning guide wheel 602 is fixed on the tensioning slide 603. The tensioning guide wheel 602 is located in the middle of the two second tracks 2 on the other side. The tensioning guide wheel 602 and the driving wheel disc of the rope saw machine 601 are located in the same vertical plane. The cutting rope 607 of the rope saw machine 601 passes around the driving wheel disc and the tensioning guide wheel 602 of the rope saw machine 601 respectively. The cutting rope 607 on the top is mounted on the rope saw machine 601. It is arranged on the topmost pipe pile to be cut, and the cutting rope 607 below is placed at the lower part of the pipe pile to be cut. The two first rails 1 are disconnected in the middle so that the cutting rope 607 below will not contact the first rail 1. A rack 604 is fixedly provided on the bottom surface between each group of two second rails 2 on both sides, and a driving gear 605 meshing with the rack 604 is respectively provided on the rope saw machine 601 and the tensioning slide 603. A tensioning motor 606 is fixedly provided on the rope saw machine 601 and the tensioning slide 603, and the output shaft of the tensioning motor 606 is transmission-connected with the driving gear 605. During the cutting process, the tensioning motor 606 drives the driving gear 605 to rotate, thereby pulling the rope saw machines 601 and the tensioning slide 603 on both sides to move in the direction away from the middle first rail 1, thereby keeping the cutting rope 607 taut during the cutting process.
[0022] like Figure 6 As shown: a dust suppression device 7 is fixedly installed on the clamping arm 502 of the clamping device 5, and the dust suppression device 7 includes a nozzle 701 and a nozzle 702.

A plurality of nozzles 702 are provided perpendicular to the nozzle 701 and are directed toward the pipe pile cutting position. The nozzle 702 is connected to the nozzle 701. During the cutting process, a large amount of concrete dust will be generated at the cutting position, and the friction between the diamond cutting rope 607 and the concrete will also generate a large amount of heat. Long-term work will cause the diamond cutting rope 607 to passivate; the nozzle 702 can spray water to the cutting position to reduce dust, and cool down the diamond cutting rope 607 to prevent the diamond cutting rope 607 from being passivated due to excessive temperature.
[0023] Working principle: The pipe pile cutting device described in the utility model can cut multiple pipe piles at the same time. When cutting is required, firstly, the clamping arms 502 on both sides of the clamping device 5 are erected vertically, and the pipe pile brackets 4 of corresponding sizes are installed on the pulley 3. The distance between the two pulleys 3 is adjusted to ensure that the single pulley 3 can stably carry the pipe piles stacked above it after the pipe piles are cut. Then, a crane is used to place the pipe piles on the pipe pile brackets 4 of the two pulleys 3 in sequence. Multiple layers of pipe piles can be stacked at the same time at one time, thereby improving the efficiency of a single cutting. After placement, the positions of the clamping arm slide 501 and the hydraulic rod slide 503 are adjusted so that the clamping arm 502 can fully contact the pipe pile as much as possible after being pressed down, and then the hydraulic rod 504 is controlled to extend so that the clamping arms 502 on both sides clamp the pipe piles, and then the cutting of the rope saw machine 601 is The rope 607 is sequentially wound around the driving wheel disc and the tensioning guide wheel 602 of the rope saw machine 601, the top of the cutting rope 607 is placed on the topmost pipe pile, and the top of the cutting rope 607 passes through the bottom of the bottommost pipe pile; then the tensioning motors 606 on both sides are controlled to tighten the cutting rope 607, and then the rope saw machine 601 is started to start cutting. During cutting, a high-pressure water source supplies water to the nozzle 701 and the nozzle 702 to cool the cutting rope 607 and reduce dust during cutting. As the cutting rope 607 continues to cut the pipe pile downwards, the tensioning motors 606 on both sides continuously pull the rope saw machine 601 and the tensioning guide wheel 602 away from both sides to ensure that the cutting rope 607 can maintain a certain tension until all the pipe piles are completely cut off, and the tensioning motor 606 is reversed to reset the rope saw machine 601 and the tensioning slide 603.
