[0030] like Figures 1 to 5 As shown, a pipe cutting machine for water conservancy construction includes: a first fixing clamp 1, a second fixing clamp 2 is provided at the first end of the first fixing clamp 1, a groove 103 is provided at one end of the opposite surface of the first fixing clamp 1 and the second fixing clamp 2, a fixing block 101 is provided at the second end of the first fixing clamp 1 and the second fixing clamp 2, and the first end is the contact end of the first fixing clamp 1 and the second fixing clamp 2; a clamping assembly 4 is arranged inside the first fixing clamp 1 and the second fixing clamp 2, and is used to clamp the pipe; a limiting assembly 5 is arranged outside the clamping assembly 4, and is used to fix the position of the clamping assembly 4; a cutting assembly 3 is arranged outside the first fixing clamp 1, and is used to cut the pipe. Specifically, when it is necessary to cut the pipe, the pipe is first clamped by the clamping assembly 4 end, and the position of the clamping assembly 4 is fixed by the limiting assembly 5 while the clamping assembly 4 clamps the pipe, so as to ensure that the clamping assembly 4 is clamped stably during use, so that the first fixing clamp 1 and the second fixing clamp 2 are connected to the pipe, so as to provide support during cutting, and ensure that the plane of the pipe cut is perpendicular to the pipe axis.

[0031] like Figures 1 to 5 As shown, both sides of the first fixing clamp 1 and the second fixing clamp 2 are provided with receiving grooves, and the first fixing clamp 1 is provided with a fixing groove 102 at one end relative to the second fixing clamp 2, and the fixing groove 102 is communicated with the receiving groove, and the receiving groove on the side of the second fixing clamp 2 is provided with bolts 201, and the bolts 201 are connected to the first fixing clamp 1. Specifically, when the first fixing clamp 1 and the second fixing clamp 2 are connected, the pipeline is placed in the receiving groove between the first fixing clamp 1 and the second fixing clamp 2, and the first fixing clamp 1 and the second fixing clamp 2 are connected by screws. During the process of cutting the pipeline, the first fixing clamp 1 and the second fixing clamp 2 provide support for the cutting assembly 3 to ensure that the port plane after cutting can meet the connection requirements.

[0032] like Figures 1 to 5As shown, the clamping assembly 4 includes a connecting rod 401, and there are multiple connecting rods 401. One end of the multiple connecting rods 401 points to the center of the groove 103, and the connecting rod 401 moves relative to the first fixing clamp 1 and the second fixing clamp 2. A contact block 402 is provided at one end of the opposite surface of the connecting rod 401, and a spring 403 is sleeved on the outer side of the connecting rod 401. Specifically, a contact pad is provided between the contact block 402 and the pipeline, and the outer side of the contact pad is coated with rubber to increase the friction between the pipeline and the contact pad. The contact pad has a certain width, so as to ensure that the axis line of the connecting rod 401 is perpendicular to the axis line of the pipeline when fixed. The telescopic connecting rod 401 cooperates with the contact block 402 to be able to adjust the diameter of the pipeline according to the diameter of the pipeline when the pipeline is cut. Automatic adjustment is performed. When cutting, the pipe is first placed between the first fixing clamp 1 and the receiving groove, and then the first fixing clamp 1 and the second fixing clamp 2 are connected by bolts 201. During the connection process of the first fixing clamp 1 and the second fixing clamp 2, the contact block 402 contacts the pipe. As the first fixing clamp 1 and the second fixing clamp 2 gradually fit together, the contact block 402 drives the connecting rod 401 to move relative to the first fixing clamp 1 and the second fixing clamp 2 under the push of the pipe. While moving, the spring 403 provides a pulling force to the connecting rod 401, so that the contact block 402 can be close to the surface of the pipe, avoiding a gap between the contact block 402 and the pipe, which causes the first fixing clamp 1 and the second fixing clamp 2 to shake.

[0033] like Figures 1 to 5 As shown, the limit assembly 5 includes a connecting bar 501 and a sliding member 6. The connecting bar 501 is in an arc shape, and there are multiple connecting bars 501. Both ends of the connecting bar 501 are provided with sliding grooves 503. The sliding grooves 503 are provided with guide rods 504 inside, and the guide rods 504 are connected to the connecting rod 401. The sliding member 6 is connected to the connecting bar 501. The sliding member 6 slides inside the first fixing clamp 1 and the second fixing clamp 2. The sliding member 6 is provided with a control rod 502 inside, and one end of the control rod 502 passes through the fixing block 101, and the control rod 50 2 is connected to the fixing block 101. Specifically, the connecting bar 501 connects the multiple connecting rods 401 inside the first fixing clamp 1 and the second fixing clamp 2 through the cooperation of the guide rod 504 and the sliding groove 503, so that the multiple connecting rods 401 can be adjusted in position synchronously, and at the same time, the pipeline is ensured to be located in the center of the accommodating groove to avoid the pipeline from being biased to one side. The control rod 502 cooperates with the sliding member 6 to fix the position of the connecting bar 501 relative to the first fixing clamp 1 and the second fixing clamp 2 to avoid the connecting rod 401 from being moved due to force after the pipeline is clamped.

[0034] like Figures 1 to 5As shown, the sliding member 6 includes a sliding column 601, and the sliding column 601 slides on the outside of the control rod 502. An extrusion block 602 is arranged inside the sliding column 601. There are multiple extrusion blocks 602, and the extrusion blocks 602 slide inside the sliding column 601. Specifically, the control rod 502 is an elliptical column. When the largest diameter side of the control rod 502 fits with the extrusion block 602, the control rod 502 squeezes the extrusion block 602 to extend out from the inside of the sliding column 601. While extending, the extrusion block 602 is connected to the first fixing clamp 1 and the second fixing clamp 1. When the side with the smallest diameter of the control rod 502 contacts the extrusion block 602, the extrusion of the extrusion block 602 is released, so that the two ends of the extrusion block 602 are separated from the first fixing clamp 1 and the second fixing clamp 2. When the sliding column 601 and the connecting strip 501 can move relative to the first fixing clamp 1 and the second fixing clamp 2, the position of the connecting rod 401 is adjusted according to the size of the pipeline.

[0035] like Figures 1 to 5 As shown, the cutting assembly 3 includes an arc bar 301, and there are multiple arc bars 301, and the arc bars 301 correspond to the first fixing clamp 1 and the second fixing clamp 2. The arc bars 301 are in an arc shape, and the centers of the multiple arc bars 301 overlap. The arc bars 301 are each provided with a connecting groove 304, and an arc block 302 is provided inside the connecting groove 304 on one side. A sliding rod 303 is provided inside the arc block 302, and the sliding rod 303 moves relative to the arc block 302. A cutter 305 is provided at one end of the sliding rod 303. Specifically, the cutter 305 includes a motor and a cutting blade. The cutter 305 is a conventional , no further elaboration is given here. A handle is also provided on the outside of the cutter 305. When the first fixing clamp 1 and the second fixing clamp 2 are connected, the arc strip 301 fits together to form a whole circle. The cutter 305 is connected to the arc block 302 through the arc block 302. The arc block 302 and the sliding rod 303 are connected through screws. When cutting the pipe, the position of the cutter 305 relative to the pipe is first controlled by the handle, and then the arc block 302 is pushed to move along the arc strip 301. While the arc block 302 moves, the cutter 305 is driven by the sliding rod 303 to rotate and cut along the pipe.
