Problems solved by technology

[0002] In the known technology, when the round pipe is butt-welded on site, the round pipe to be butt-welded is mainly moved manually, and the butt-welding is carried out through human observation, so the coaxiality is difficult to guarantee, and the labor intensity of the workers is very high; Seam gap control is mainly achieved by clamping welding rods or steel strips, which is easy to loose and lacks accuracy, which may eventually result in substandard products and waste
In short, the whole butt welding process is difficult to operate, the overall accuracy is poor, and the requirements for workers' operation level are also very high

Embodiment Construction

[0021] As shown in Figure 1 and Figure 2, the positioning sleeve of the round pipe butt welding quick alignment and positioning device is a two-lobed split of the half positioning sleeve 1 of the third part and the half positioning sleeve 2 of the two third part The structure is cylindrical. The axial direction of the positioning sleeve has left and right symmetrical taper holes 3 and 4. There is a coaxial round hole 5 between the two taper holes. The round hole 5 connects the two taper holes 3 and 4 to form two left and right There are three stepped holes 8 evenly distributed on the outer circumference of the positioning sleeve, intersecting with the two tapered holes 3, 4 and the round hole 5; one side of the two and a half positioning sleeves 1, 2 The junction is articulated by a hinge 9; the clamping device 10 includes lugs respectively provided on the other junction of the two half positioning sleeves 1 and 2 and a screw nut mechanism connecting the lugs.

Abstract

The invention relates to a circular duct butt-welding rapid spotting and locating device and a circular duct butt-welding method. The circular duct butt-welding rapid spotting and locating device comprises a locating sleeve, a clamp device, and a tensioning device, the locating comprises a composite structure of two semi locating sleeve, bilaterally symmetrical tapered bores are arranged in the axial direction, a coaxial line circular hole is arranged between two tapered bores, thereby forming a left step rabbets and a right step rabbets, a plurality of radial step holes connected with the two tapered bores and the circular hole are arranged on the periphery of the locating sleeve; the joint part of the side of the two semi locating sleeves is hinged; the clamp device comprises two ear plates arranged on the two semi locating sleeve and a bolt and nut mechanism. The circular duct butt-welding method utilizes the structural characteristics of the tapered bore and the step rabbet of the device, and combines the groove shape of the circular duct which is required to be welded, by the help of the clamp device and the tensioning device, the rapid spotting, locating and tensioning of the circular duct butt-welding are realized, the problems that the accuracy of manual spotting, locating, and tensioning operation is poor, the labor intensity is strong, and the efficiency is low, etc. are solved, the requirements of axiality, the size of welding seam clearance, and no fault of the circular duct butt-welding are met.
