Technical Field
The utility model relates to cutting equipment, in particular to a cutting device for a large-diameter pipe body.
Background
On the construction site, when the ductile cast iron pipe with the diameter of 600-1600mm needs a short pipe, construction personnel are required to use a manual electric tool to carry out on-site cutting, the operation site environment is complex, time and labor are wasted when the cast pipe is cut, potential safety hazards are easily caused to operating personnel, and the cutting surfaces are uneven. Inconvenience is brought to installation and quality.
The manual cutting of 1.2 meters diameter pipe needs more than 4 man-hours, consumes physical power moreover, because the strength and the progress of operator control cutting machine are uneven, the cutting piece often blocks and burns out the motor, cuts a pipe and burns out 4 angle buffing machines sometimes. Due to the uneven edges of the tube that are manually cut, it is also necessary to repair the edges with an angle grinder.
When the tube is manually cut, although glasses and a mask are worn, iron foam and dust sometimes cause damage to eyes and a respiratory system, and particularly, when a cutting piece is broken, the damage to an operator is larger.
Professional cutting machines are very expensive and therefore require a low cost tool.
