Description

Technical Field

[0001] This utility model belongs to the field of welding technology, specifically relating to a blast furnace shell longitudinal seam assembly adjustment device. Background Technology

[0002] The blast furnace shell is constructed by welding together multiple massive, curved steel plates into a cylindrical strip. When fabricating a single-strip shell, the first step is to assemble and weld the multiple longitudinal seams of each curved steel plate. The quality of the longitudinal seam assembly directly determines the stress level of the weld and the roundness of the shell after welding. Traditional methods use wedges to push the seams locally, which is time-consuming, labor-intensive, and inefficient. Furthermore, it is difficult to achieve uniform control of the gaps along the entire long seam, easily resulting in excessively large or small gaps in certain areas, thus affecting the welding quality.

[0035] The main body 2 is hung on the middle of the insert 10 via the hook 4, and the upper part of the insert 10 extends out from the opening.

[0036] A second sliding groove 18 is provided on the main body 1, located between two openings 3; a second slider 19 is provided in the second sliding groove 18, and a fifth screw hole 20 is provided on the upper part of the second slider, and a third bolt 21 is provided in the fifth screw hole 20. A third bearing 22 is provided at the end of the third bolt 21, that is, the end of the third bolt 21 is fixedly connected to the inner ring of the third bearing 22, and a washer 23 is welded to the end of the third bearing 22 near the insert side.

[0037] This invention achieves the longitudinal seam assembly of the furnace shell as follows: A pair of hanging plates 2 are welded at the same horizontal level (9 degrees) to the two furnace shells to be assembled, and multiple pairs of hanging plates 2 are welded along the longitudinal seam. Insert plates 10 are inserted into the hanging plates 2 and connected with screws 15. The main body 1 is hung on the insert plates 10, that is, the hanging ears 4 are placed in the middle of the insert plates 10, with the upper part of the insert plates 10 protruding from the opening. Then, by adjusting the position of the first slider 6 and tightening the first bolt 8, the washer 23 located on the first bearing 16 can be pressed onto the insert plate 10. By tightening the two first bolts 8, the left and right furnace shells 9 can be brought closer together. Next, the second bolt 12 is adjusted so that the washer 23 located on the second bearing 17 presses onto the hanging ears 4. By adjusting the tightness of the two second bolts 12, the left and right furnace shells 9 can be aligned front to back. That is, when the second bolt 12 is tightened, tension is created between the hanging ears 4 and the hanging plates 2, thereby aligning the left and right furnace shells 9 front to back. Because the furnace shell 9 is relatively high, there may be instances where two furnace shells 9 intersect or are too close together at a certain point. In such cases, loosening the first bolt 8 and tightening the third bolt 21 will cause the washer 23 on the third bearing 22 to press against the insert 10, thus pushing the two furnace shells 9 apart and ensuring that the width of the longitudinal seam between them meets the welding requirements. After the longitudinal seam welding is completed, loosen the first bolt 8, the second bolt 12, and the third bolt 21, remove the main body 1, and loosen the screw 15 to remove the insert 10. Except for the hanging plate 2, the other components of this device can be reused multiple times.
