Abstract

,The invention discloses a steel pipe cutting device and method. The steel pipe cutting device comprises a supporting frame used for horizontally erecting a steel pipe in an overhead mode and a rotary cutting frame used for fixing a cutting machine, the rotary cutting frame comprises at least two double-layer frame bodies which are detachably connected the inner rings of the at least two double-layer frame bodies are spliced to form a sleeve opening for rotationally sleeving a steel pipe, the outer rings of the at least two double-layer frame bodies are connected to the outer sides of the inner rings through fixing rods, and one of the outer rings is provided with a fixing base allowing the cutting machine to be installed. The rotary cutting frame is directly arranged on the steel pipe in a sleeving mode to fix the cutting gun, the rotary cutting frame is rotated to cut the steel pipe, and the technical problem that in the prior art, steel pipe cutting is conducted under the complex site working condition and the narrow site is solved. The device is convenient to operate, neat in notch section, high in cutting speed, straight in section, small in size of the rotary cutting frame, convenient to move, suitable for complex environments, low in site requirement and suitable for operation in the complex environments.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a steel pipe cutting device and method. Background technique [0002] In the field of shield tunneling construction, circulating water pipes, sewage pipes, mud pipes, etc. used in shield tunneling construction are generally connected by flanges or hoops. Water pipes and mud pipes have been cycled and used many times, and the flanges or pressure grooves at both ends of the pipeline will be deformed. It is difficult or even impossible to connect the two pipelines. It is necessary to cut off the damaged flanges or pressure grooves at both ends of the pipeline, and re Weld flange or groove. The general cutting method at the construction site is oxyacetylene cutting, which is prone to uneven cutting, and cannot efficiently weld flanges or use a grooving machine to make grooves, and the grooving and welding flanges have high requirements for the flatness of the section cutting, an...
