Embodiment 1

[0020] Embodiment 1: as figure 1 When the connecting tool is applied to the butt joint of large-diameter steel pipes, the tool only needs to be assembled on the fixed cylindrical steel pipe at first, and then the free cylindrical steel pipe and the fixed cylindrical steel pipe are docked and fixed when the welding operation is required. It is mainly used as an auxiliary tool for welding or kit construction after the ends of large-diameter steel pipes are accurately butt-jointed. And it can be applied to some emergency fields, such as alignment welding after pipeline rupture. When this tool is applied to the workshop to implement the butt joint of two equal-diameter or different-diameter steel pipes, it can also achieve fast and accurate butt joint effects. The tool mainly includes four main components including a fixed lock piece, a movable lock piece and two locking devices. The fixed lock, the movable lock and the locking device are independently assembled components. For ...

Embodiment 2

[0026] Embodiment 2: On the basis of Embodiment 1, the form of the sliding sleeve can be changed. The sliding sleeve adopted in embodiment 1 is a closed cylinder sliding sleeve, while the sliding sleeve used in this embodiment has a semi-closed sliding sleeve with cracks on the circumferential side. When the semi-closed sliding sleeve is used, upwardly protruding flanges are respectively provided on the two ends of the crack, and connecting holes are respectively arranged on the flanges, and connecting bolts run through the connecting holes.

Embodiment 3

[0027] Embodiment 3: On the basis of Embodiment 1, arc-shaped spacers are fixed on the bottom surface of some or all of the chain links of the fixed chain or movable chain, and each arc-shaped spacer is approximately consistent with the arc of the side wall of the cylindrical tube.

Abstract

The invention provides a large-diameter steel pipe butt-joint auxiliary connection tool, which comprises a fixed lock piece, a moving lock piece and a locking device. A fixed chain of the fixed lock piece surrounds the end of a fixed cylindrical steel pipe, the two ends of the fixed chain are locked to form a ring-shaped fixed chain through the locking device, the moving lock piece is fixed at thecenter of the circumferential surface of a cylindrical sliding sleeve in a ring sleeving mode, each moving connecting shaft plate is fixedly connected together with a corresponding pair of chain shafts, a moving vertical plate is further vertically fixed at the outer end of each moving connecting shaft plate, the moving vertical plates are provided with perforated holes and connected together with bolts in a sleeving mode, and by tightening the bolts and corresponding nuts, the fixed lock piece and the moving lock piece get close to each other until the position cannot be no longer closed. According to the large-diameter steel pipe butt-joint auxiliary connection tool, an adjustment mode is simple, compaction is firm and reliable, a reliable guarantee is provided for rapid fixing of the fixed lock piece and the moving lock piece, and the site construction efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of construction auxiliary tools for steel structure machinery, and in particular relates to an auxiliary connection tool capable of adjusting large-diameter steel pipes to achieve precise docking. Background technique [0002] Steel pipe butt jointing is a common construction process in construction engineering. The conventional butt joint process of nozzle welding is to set a limit plate on the pipe wall on one side of the joint, and lift the butt steel pipe on the other side to close to the limit plate. Then weld the nozzle to the seam. For example, a steel pipe butt straightening mechanism whose publication number is CN 209551017 U includes a first steel pipe and a second steel pipe with the same pipe diameter, at least one set of auxiliary straightening components and a steel liner; the steel liner is in the shape of a short tube, and the outer The diameter matches the inner diameter of the first steel ...
