Description

Technical Field

[0001] The utility model relates to the technical field of pipe piles, in particular to a prestressed pipe pile cutting device. Background Art

[0002] Prestressed pipe piles are mainly composed of cylindrical pile bodies, end plates and steel hoop. Prestressed pipe piles have high vertical load bearing capacity and are often used in low pile caps for industrial and civil buildings. During the construction process, operators first drive multiple prestressed pipe piles into the ground soil, and then cut the prestressed pipe piles according to the use requirements to make the prestressed pipe piles of appropriate length. Currently, operators are required to use handheld cutting machines to cut multiple prestressed pipe piles in turn, but the operation process is cumbersome and the operator's hands are easily injured;

[0003] In the prior art, the Chinese utility model with publication number: CN218192845U discloses a prestressed pipe pile cutting device, which includes a circular cover plate, a mounting tube, a clamping strip, a driving assembly and a cutting assembly; the circular cover plate is coaxially connected to the mounting tube, and the circular cover plate is in abutment with the top wall of the prestressed pipe pile; the number of the clamping strips is at least three, and the clamping strips are slidably connected to the mounting tube; the driving assembly is used to move the clamping strips along the radial direction of the mounting tube; and the cutting assembly is used to cut the prestressed pipe pile. The designed prestressed pipe pile cutting device provides power for the clamping strips to move radially along the mounting tube through the driving assembly, and the cutting of the prestressed pipe pile is achieved through the cutting assembly. The entire cutting device is fixed to the prestressed pipe pile through the cooperation of the clamping strip and the mounting tube, thereby reducing the possibility of the entire cutting device tilting to one side of the cutting assembly, so that the plane where the blade of the cutter is located is perpendicular to the axis of the prestressed pipe pile, thereby improving the cutting efficiency;

[0004] There are still some problems in the above technical solution. When the cutting device completes cutting the pipe pile when the tightening strip is located above the cutting surface, since the cutting device is installed at the upper end of the pipe pile, it loses the support of the bottom pipe pile, causing the cutting device to cause the top pipe pile to fall due to the shift of the center of gravity, which may injure the staff. The stability of the cutting device during cutting needs to be further improved. Therefore, we need to propose a prestressed pipe pile cutting device. Utility Model Content
