Abstract
The utility model relates to an aligning device of a large-caliber pipeline, comprising a spiral jack. The aligning device is characterized in that two ends of the spiral jack are respectively connected with a section of connecting pipe or connecting rod; and an arc surface plate is arranged at the end part of the connecting pipe or the connecting rod. The aligning device has the advantages that the manual operation is convenient, a base material is not damaged and the cost is low.
Description
Technical field:
The utility model relates to a kind of large diameter pipeline contra-aperture device, belongs to the aid field of pipeline counterpart welding.
Background technology:
At present, large diameter pipelines such as industrial gas pipeline, dust removal by ventilation pipeline (can at the pipeline of pipe interior counterpart operation), conventional construction method is to carry out counterpart at inner-walls of duct border spot welding chock or spot welding crowbar, counterpart finishes and re-uses gas welding and slice off chock and with sanding machine overlap is polished, this construction method not only efficient is slower, and consume a large amount of grinding wheel wastes greatly, be exactly that the spot welding chock can injure mother metal in addition.
Summary of the invention:
The purpose of this utility model is the principle according to internal clamp, and a kind of manually-operated of being convenient to is provided, and does not hinder mother metal, large diameter pipeline contra-aperture device with low cost.
The purpose of this utility model realizes in the following manner:
The utility model comprises screw jack, it is characterized in that: be connected with one section tube connector or connecting rod respectively at the two ends of screw jack, the end of tube connector or connecting rod is provided with cambered plate.
The utility model has the advantages that: be convenient to manually-operated, do not hinder mother metal, with low cost.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is a user mode reference diagram of the present utility model.
The specific embodiment:
With reference to accompanying drawing, the utility model comprises screw jack 1, and screw jack 1 adopts the 16t screw jack, is connected with one section seamless steel pipe 2 respectively at the two ends of screw jack 1, is provided with cambered plate 3 in the end of seamless steel pipe 2.The length of seamless steel pipe 2 determines that according to the butt joint pipe diameter bending radius of cambered plate 3 is identical with the radius of butt joint pipeline 4.
During application, the large diameter pipeline group is made the support of overlap joint or rail mounted of the 20# channel-section steel to the bottom, as long as pipe is controlled the gap end well like this, set up jointly having required with regard to basic symbols, vertically be placed on place, pipeline slit with this device then, strut jack, summit of pipeline and base point are welded, it is right just to have finished this group of 2; Then near the some position that point welds, the less angle of this device rotation is backed down 2 points at diagonal angle, make the some position of backing down now all echo group to requiring with putting weld gap between the fixing point that welds, misalignment etc., spot welding is fixed; Rotate this device successively, fixing a plurality of spot welding points position, the density of fixing point is decided with actual conditions; Withdraw from this device at last, the welding weld bond.
