Drawings
FIG. 1 is a front view of the present invention;
fig. 2 is a left side view of the present invention.
The components in the figure: the device comprises a top column 1, an arc plate 2, a main frame 3, a connecting plate 4, a butt-joint connecting plate 5, a long adjusting block 6 and a short adjusting block 7.
Detailed Description
The present invention will be described in detail with reference to the embodiments shown in the drawings.
The utility model relates to an outer ware of keeping to needs of pipeline, including fore-set 1, arc board 2, main frame 3, connecting plate 4, keep to the mouth connecting plate 5, long adjusting block 6 and short adjusting block 7. The main frame 3 is composed of four semicircles. The main frame 3 is the main body of the external orifice aligning device of the pipeline and plays a role of connecting other structures. The two-end connector is composed of four semicircular structures, and two ends of two semicircles are connected with a connecting plate 4 and a butt-joint connecting plate 5 respectively through threads to form a double-layer semicircular structure during assembly. The connecting plate 4 and the butt-joint connecting plate 5 are of inserting structures, and pin shafts are respectively inserted to form a whole circle to form a main frame 3; the long adjusting block 6 and the short adjusting block 7 are main stress structures of the external orifice aligning device of the pipeline, and the long adjusting block 6 and the short adjusting block 7 are alternately fixed on the main rack 3 in a screw connection mode; threaded holes matched with the jacking columns 1 are drilled in the long adjusting block 6 and the short adjusting block 7, and the jacking columns 1 are respectively installed on the long adjusting block 6 and the short adjusting block 7 through threaded connection; finally, the arc plates 2 are respectively mounted on the top pillars 1. The top column 1 mainly plays a role in fixing a pipeline and aligning a pipe orifice; the arc plate 2 mainly has the function of matching the outer diameter of the pipeline; the long adjusting block 6 and the short adjusting block 7 mainly serve to connect the jack-posts 1. When the jack is aligned, the long adjusting block 6 and the short adjusting block 7 are subjected to bending stress in the radial direction by the jack 1. Therefore, the material of the long adjusting block 6 and the short adjusting block 7 needs to have higher yield strength, so as to realize smooth opening alignment. The mouthpiece is made of aviation alloy aluminum 7075 serving as a main material, the high-strength heat-treatable alloy is adopted, the tensile strength of heat treatment T6 is 560MPa, the elongation is 7%, the yield strength is 361MPa, the hardness is HB150, and the mechanical performance index of the mouthpiece is far higher than that of common low-alloy steel; the material density is 2.8 g/cm 3; easy processing and good wear resistance; the corrosion resistance and the oxidation resistance are good; the length of the cantilever of the adjusting block is increased, and the requirements of argon arc backing welding on site are met.
During construction, the pin shaft between the connecting plate 4 and the butt-joint connecting plate 5 at one end of the external pipe butt-joint device is opened, the external pipe butt-joint device is sleeved at the pipe orifice of the pipe, and then the pin shaft is installed back to the original position. The even clockwise rotation fore-set 1 of mouth ware one end is followed to the circumference outside the pipeline, makes arc plate 2 press from both sides on the pipeline, and the other end also makes arc plate 2 press on newly trading the pipeline along the even clockwise rotation fore-set 1 of circumference, makes the crater of two pipelines adjust the back well, welds again. After the mouth is welded, the mouth aligning device is disassembled into two halves, the two halves are moved to a new connecting pipe for mouth aligning, four auxiliary arc top caps are arranged on the fixed original pipe part, and the arc plates of the fixed part are prevented from being pushed to be deviated when the new pipe is aligned.
