Description

Technical Field

[0002] The cutting device for construction steel pipes is a device specially used for cutting steel pipes. It has various types and characteristics to meet the cutting needs in different scenarios. When selecting a cutting device for construction steel pipes, factors such as cutting frequency, accuracy, steel pipe type (such as material, diameter, thickness) and working environment (such as flammable and explosive places) should be considered according to actual needs.

[0003] After checking the announcement number: CN214023767U, an efficient construction steel pipe cutting device is disclosed. This technology discloses "including a bottom plate, two dovetail slide grooves are symmetrically arranged on the top surface of the bottom plate, dovetail sliders are arranged in the two dovetail slide grooves and are slidably connected with them, and the top surface of the dovetail slider extends out of the dovetail slide groove and is fixedly connected with a support rod and other technical effects, which can adjust the distance between two adjacent sleeves according to the length of the steel pipe cut according to the work needs, and can also adjust the distance between two adjacent cutting discs according to the length of the steel pipe cut according to the work needs, and then start the first motor and the second motor to operate simultaneously, so that the steel pipe rotates and slowly approaches the rotating cutting disc for cutting, so that the cutting is faster, and the steel pipe can be effectively cut into multiple sections at one time, and steel pipes of different lengths can be cut according to the work needs.
