Problems solved by technology

The problem with this method is that when the diameter of the pipe is large, two people must operate at the same time to complete the work of drawing the line, which is a waste of manpower, and cutting according to the drawn line is often impossible to ensure that it is even, which affects the connection of the last new pipe section , sealing effect
Moreover, in industrial production, in some special cases, it is necessary to install and weld some parts inside the pipeline, but if there is a problem with the internal parts of the pipeline, it needs to be removed or cut off and reinstalled with new parts. In the current situation, the internal parts of the pipeline There is no way to cut it down. Once there is a problem with the internal parts of the pipe, the pipe can only be discarded and replaced with a new one, causing great waste

Abstract

The invention relates to a cutting device and more particularly relates to a cutting device in a pipeline. The cutting device comprises a driving motor, a speed changing box, a transmission shaft, a disc, fixed rods, sliding rods, strong magnets and cutting saw discs. The cutting device is characterized in that the transmission shaft is connected with the driving motor by the speed changing box; the tail end of the transmission shaft is fixedly connected together with the disc; and three fixed rods are welded on the outer wall of the disc in array distribution, and are internally provided with the sliding rods in a telescopic sliding manner. The cutting device has the advantages that in the cutting process, the strong magnet I and the strong magnet II act on the pipe wall all the time by the cutting saw discs at the tail ends of the sliding rods, and the pipelines with different diameters can be cut, so that the adaptability is strong.

Description

technical field [0001] The invention relates to a cutting device, in particular to a cutting device in a pipeline. Background technique [0002] At present, the commonly used cutting method for pipes is generally manual cutting with a hacksaw. When cutting a pipe with a larger diameter, first surround the outer wall of the pipe with a circle, then draw a line along the circle with a pen, and then follow the drawn line. line for cutting. The problem with this method is that when the diameter of the pipe is large, two people must operate at the same time to complete the work of drawing the line, which is a waste of manpower, and cutting according to the drawn line is often impossible to ensure that it is even, which affects the connection of the last new pipe section , Sealing effect. Moreover, in industrial production, in some special cases, it is necessary to install and weld some parts inside the pipeline, but if there is a problem with the internal parts of the pipeline,...
