Steel pipe cutting positioning device

Abstract

The invention relates to a steel pipe cutting positioning device. The steel pipe cutting positioning device comprises a tensioning pull rod, a movable sleeve, a positioning sleeve, a bearing, a retaining plate, a protection pipe, a cutting torch mounting accessory, multiple groups of positioning support sheets, multiple groups of fixing sheets and the like. The corresponding fixing sheets are welded to one end of the tensioning pull rod, the movable sleeve sleeves the tensioning pull rod, the corresponding fixing sheets are welded onto the movable sleeve, the positioning sleeve sleeves the tensioning pull rod close to the movable sleeve, the corresponding fixing sheets are welded to one end, close to the movable sleeve, of the positioning sleeve, the retaining plate is welded on the positioning sleeve and close to the fixing sheets, the protection pipe sleeves the middle of the positioning sleeve, the bearing is mounted at the other end of the positioning sleeve and sleeved with the cutting torch mounting accessory, the positioning support sheets in all the groups are identical in number, the fixing sheets are movably connected with the corresponding positioning support sheets, and first positioning support sheets, fourth positioning support sheets and second fixing sheets are respectively clamped on two sides of first fixing sheets, second positioning support sheets, third positioning support sheets and third fixing sheets connected with two ends thereof. The steel pipe cutting positioning device is mainly used for effective positioning when steel pipes are cut.

Description

technical field [0001] The invention relates to a positioning device used in steel pipe cutting. Background technique [0002] When cutting steel pipes, due to the influence of manual line drawing errors and the technical level of gas welders, it is often necessary to cut and repair repeatedly, which not only affects the efficiency, but also makes it difficult to guarantee the quality. The use of automatic and semi-automatic cutting equipment can improve cutting quality and efficiency. At present Commonly used automatic and semi-automatic cutting equipment (magnetic automatic cutting machine, chain automatic pipe cutting machine, positioning block type pipe cutting machine, track chain compound automatic pipe cutting machine, etc.) need to be positioned on the outer wall of the pipeline, which is relatively heavy and expensive High, not suitable for small construction teams with strong mobility. Contents of the invention [0003] In view of the above-mentioned defects in ...
