[0010] Beneficial Effects
[0011] The utility model provides a simple PCCP pipe cutting device, which has the following beneficial effects: the scheme uses an adjustable rolling support structure, which is composed of a frame structure with adjustable angle and a cutting machine. The angle of the frame can be adjusted according to the cutting requirements, and the whole device can be fitted to the outer wall of the pipe, making the cutting more labor-saving and ensuring the cutting accuracy of the pipe.

DETAILED DESCRIPTION
[0016] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
[0017] Example: See Figure 1-3 The utility model provides a technical solution: a simple PCCP pipe cutting device. This solution takes into account that it is difficult to directly cut the existing PCCP pipe by a cutting machine during construction, and direct manual cutting cannot guarantee the accuracy of pipe cutting, which affects the connection sealing of the pipe. Based on the above content, this case sets the following technical means;
[0018] Specifically, the device at least comprises: a cutting fixed plate 1, a cutting machine 2, two pairs of connecting blocks 3, a pair of angle adjustment plates 4, a pair of fixed brackets 5, two pairs of first rotating hinges 6, two pairs of adjustment rods 7, two pairs of second rotating hinges 8, two pairs of telescopic rods 9, two pairs of locking knobs 10, a plurality of embedding grooves 11 and a plurality of supporting rollers 12;
[0019] When it is necessary to cut the pipe, rotate the locking knob 10 to open it, adjust the telescopic length of the telescopic rod 9 inside the adjusting rod 7, and cooperate with the first rotating hinge seat 6 and the second rotating hinge seat 8 to adjust the bending angle of the angle adjustment plate 4 installed on the cutting fixing plate 1 through the connecting block 3, so that the angle of the combination of the three plates just fits the outer wall surface of the pipe. When the adjustment is completed, fix it through the locking knob 10, and make the equipment fit tightly to the outer wall of the pipe by holding the handle 15. Start the cutting machine to cut the pipe. At the same time, the support roller 12 installed in the embedding groove 11 drives the equipment to move on the outer wall of the pipe, which can effectively reduce the external force required by the staff for cutting. At the same time, the roller structure can ensure that the cutting is in a straight line to ensure the cutting accuracy.
[0020] In the specific implementation process, further, the cutting machine 2 is installed on the cutting fixing plate 1 through the fixing bolts 13.
[0021] In the specific implementation process, further, a pair of angle adjustment plates 4 are installed on two pairs of connection blocks 3 through two pairs of rotation shafts 14 .
[0022] In the specific implementation process, further, a pair of holding handles 15 are installed on the cutting fixing plate 1.
