Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy project construction, and in particular relates to a water conservancy project pipeline cutting machine. Background Art

[0002] The main work content of water conservancy projects is to regulate and control the natural surface water and groundwater. By building various water conservancy projects such as dams, river banks, spillways and channels, the functions of controlling water flow, flood control, irrigation and power generation are achieved. In the construction process of water conservancy projects, pipelines are needed. Through pipeline construction, surface water and groundwater are regulated and controlled. During the pipeline construction process, cutting is required to meet the construction and installation requirements.

[0003] Existing water conservancy project pipe cutting machines can fix and cut water conservancy project pipes by setting a cutting component to prevent the pipes from moving during the cutting process. By setting a supporting component, the box body can be supported to improve the stability of the box body. In this embodiment, by combining the cutting component and the supporting component, the water conservancy project pipe can be fixed and cut, which saves time and effort, has high cutting efficiency, and is more suitable for promotion and use.

[0004] During the construction of water conservancy projects, there are various requirements for pipe cutting. For example, when two perpendicular pipes are connected, one of the pipes needs to be cut with an arc-shaped connection. When two inclined pipes are connected, one of the pipes needs to be bevel-cut. However, existing water conservancy project pipe cutting machines can only complete straight-face cutting of pipes and cannot meet the diverse cutting requirements of pipes, resulting in poor progress in pipe construction, which in turn affects the construction progress of water conservancy projects.

The connecting assembly 650 not only ensures that the clamping and moving wheel 640 can move arbitrarily in the second installation groove 620 by stretching, so that the clamping and moving wheel 640 can effectively clamp and fix pipes of different diameters, but also ensures that the connection relationship between two adjacent clamping and moving wheels 640 is always maintained, thereby ensuring that the multiple clamping and moving wheels 640 are stably connected to each other, which is convenient for the multiple clamping and moving wheels 640 to push the pipe horizontally at the same time in the later stage, thereby changing the cutting path of the pipe; When the driving component 660 drives the connecting component 650 connected to it to rotate, the connecting component 650 drives the clamping and moving wheels 640 on both sides thereof to rotate on the mounting bracket 630. Similarly, the multiple clamping and moving wheels 640 on one side of the connecting plate three 610 can rotate at the same time.
