The invention discloses a power pipe cutting device for power construction, and belongs to the field of power construction equipment. The device comprises a base, a lifting support, an installation plate, a cutting device and an intermittent device. The lifting support is provided with a lifting sliding groove and a reversing tooth groove, a reversing rack is arranged in the reversing tooth groove, the installation plate is provided with a lifting sliding block matched with the lifting sliding groove, the lifting sliding block is slidably arranged in the lifting sliding groove, the cutting device comprises a cutting motor and a cutting blade, wherein the cutting motor is installed on the installation plate and used for driving the cutting blade to rotate, the intermittent device comprisesa first transmission gear, a second transmission gear, a transmission shaft and an incomplete gear, and the first transmission gear is coaxially arranged on an output shaft of the cutting motor in a driven mode. The device can be intermittently far away from and close to a pipe, cutting is not generated when the device is far away from the pipe, a grinding wheel sheet rotates to take away heat bymeans of airflow generated by high-speed rotation, and halt caused by excessive knife consumption is avoided.
Description
technical field [0001] The invention relates to the field of electric power construction equipment, in particular to a power pipe cutting device for electric power construction. Background technique [0002] At present, most of the cutting operations for pipes, especially stainless steel pipes, are done by grinding wheel saws. The cutting speed of the grinding wheel saw is relatively fast, the efficiency is high, and it can adapt to a variety of materials and is widely used. However, during use, the friction between the grinding wheel and the pipe generates a lot of heat, which often needs to be cooled by air cooling or coolant to prevent the service life of the grinding wheel from being reduced. In addition, for some pipe fittings with relatively hard materials, due to the large friction force during cutting, it is often easy to cause the friction force on the grinding wheel to be greater than the driving force, resulting in a decrease in speed or even stop rotation. The ...
