Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a cutting device for laying water conservancy pipelines. Background Art

[0002] Water conservancy projects are projects built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Water is a valuable resource indispensable to human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flows, prevent floods and waterlogging disasters, and regulate and distribute water to meet the needs of people's lives and production for water resources. Water conservancy projects need to build dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways and other different types of hydraulic structures to achieve their goals. Water conservancy projects require the laying of pipelines. The laying of pipelines has different requirements for length, and the pipelines need to be cut to the appropriate length before laying and installing.

[0003] For example, announcement number CN215698388U discloses a cutting device for laying pipes in water conservancy projects, the cutting device for laying pipes in water conservancy projects comprises a box body and a cutting mechanism, the cutting mechanism comprises a sliding rod, one side of the first fixed block is fixedly connected to one side of the operating table, the outer side of the sliding rod is slidably connected to the inside of the sliding block, the top of the sliding block is fixedly connected to the bottom of the fixing frame, the inside of the fixing frame is fixedly connected to the bottom of the cylinder, and the output end of the motor is fixedly connected to the cutting blade. The cutting device for laying pipes in water conservancy projects provided by the utility model solves the problems that the existing pipe cutting device is cumbersome to operate during use, has low cutting size accuracy, has poor cutting effect when cutting pipes of different specifications, and has certain risks in the cutting process, such as splashing of pipe fragments, and the singleness of the device makes the device unable to be adjusted, which is not conducive to pipe cutting.

[0004] However, although this kind of cutting device for laying water conservancy pipelines can perform good cutting operations on the pipeline surface when in use, the polishing effect of the cut end face of the pipeline after cutting the pipeline is not high, so that burrs will appear on the end face of the pipeline, which reduces the comfort of the hands of the installers when manually carrying the pipeline, reduces the accuracy of the position when the pipeline is butt-jointed and installed, and affects the fit between the pipelines.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a cutting device for laying water conservancy pipelines is proposed. Utility Model Content
