Description

Technical Field

[0001] The invention relates to the technical field of cutting devices, and in particular to a pipeline cutting device for water conservancy projects. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging disasters, and regulate and distribute water to meet the needs of people's life 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. With the development of society, the application of pipe cutting equipment for water conservancy projects has become more and more extensive.

[0003] Most of the pipe cutting equipment for water conservancy projects on the market cannot feed materials automatically and require manual operation, resulting in low work efficiency and poor practicality. In addition, they cannot perform fixed limits on pipes of different diameters, which has large limitations and is inconvenient to use. At the same time, they cannot absorb and clean the generated debris, affecting the environment around the device. To this end, technical personnel in this field have conducted research and improvements, such as a pipe cutting equipment for water conservancy projects with application number CN202122114791.9. This technical solution can limit the position of pipe bodies of different diameters through the limiting pulley by setting a telescopic tube, a spring, a limiting pulley, a second electric cylinder, a motor and a driving roller, and by setting a second electric cylinder and a motor, the driving roller can drive the pipe body to automatically feed. However, the device still has many defects:

[0004] 1) The cutting length in this device is not easy to control, which affects the cutting accuracy;

[0005] 2) The pipe in the device cannot rotate, and it is difficult to cut water conservancy pipes with larger diameters;

[0006] 3) The device cannot accept and transfer the cut pipes, making unloading inconvenient.
