Buried pipe cutting device and cutting method thereof

Abstract

The invention discloses a buried pipe cutting device and a cutting method thereof. The buried pipe cutting device comprises a driving motor. The outer wall of the driving motor is provided with supporting cylinders, rolling wheels and air injection assemblies. An output shaft of the driving motor is provided with a mounting plate, and the mounting plate is provided with a plurality of cutting cylinders. The ends of piston rods of the cutting cylinders are provided with cutting knives. The cutting method includes the following steps that a controller controls the air injection assemblies to move along a buried pipe; after the buried pipe arrives at a position, the buried pipe cutting device is stopped, the controller controls piston rods of the supporting cylinders to be stretched out, supporting blocks on the piston rods act on the inner wall of the buried pipe, the driving motor is strutted up, and the buried pipe cutting device is fixedly supported at the center of the buried pipe; the controller controls the piston rods of the cutting cylinders to be stretched out, and the cutting knives extend to be tightly pressed onto the inner side wall of the buried pipe; and the driving motor rotates, and the cutting knives cut the buried pipe from the inner wall of the buried pipe.

Description

technical field [0001] The invention relates to a cutting device and a cutting method thereof, in particular to a buried pipe cutting device and a cutting method thereof. Background technique [0002] In municipal engineering, it is usually necessary to bury the pipeline underground. When the buried pipeline needs to be cut, it is often necessary to excavate the filling above it, and the buried pipeline can only be cut after it is exposed to the external environment. It is very troublesome, especially when the buried pipe passes through the above-ground engineering structure, it causes great difficulty in cutting the buried pipe, and the cutting cost is very high. Contents of the invention [0003] The first technical problem to be solved by the present invention is to provide a buried pipe cutting device according to the current state of the art, which can cut buried pipes without filling and digging, with low cutting cost, high efficiency and simple operation .
