[0013] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments.
[0014] Referring to Figures 1 to 4 A kind of connecting structure of converter shell and support ring, including converter shell 1 and support ring 2, the lower part of support ring 2 is equipped with multiple trunnion ring one 201, the outside of converter shell 1 is equipped with adjusting mechanism, adjusting mechanism is equipped with multiple trunnion ring two 401, the position of trunnion ring two 401 is adjusted by adjusting mechanism to facilitate trunnion ring one 201 mutual cooperation installation, adjusting mechanism includes: stepped ring 101, the outside of converter shell 1 is integrally formed and fixedly connected with stepped ring 101.
[0015] Preferably: the step ring 101 is annular, with a short inner side and a high outer side. The outer side of the step ring 101 is also provided with a smooth surface 102, and the outer surface of the smooth surface 102 is semi-circular. The outer clearance of the step ring 101 is fitted with a sliding sleeve connected to the connecting shell 4. The inner and outer sides of the step ring 101 are wrapped inside the connecting shell 4. A plurality of ear shaft rings 401 are fixedly installed on the upper part of the connecting shell 4. Since the outer sliding sleeve of the step ring 101 is fitted with the connecting shell 4, it can be held by hand or with an existing rotary tool. The edge of the shell 4 is slidably connected to the shell 4, so that the ear shaft ring 2 401 on the connecting shell 4 and the ear shaft ring 1 201 are on the same axis with each other, and then the ear shaft ring 2 401 and the ear shaft ring 1 201 are connected to each other through the chain plate 3 and the bolt 301, thereby solving the problem that the ear shaft ring 2 401 of the converter shell 1 and the ear shaft ring 2 401 are not in the same straight line during lifting. By providing a smooth surface 102, the sliding friction between the connecting shell 4 and the step ring 101 can be greatly reduced.
[0016] Preferably, there are eight ear shaft rings 401 and ear shaft rings 201 in total, wherein the eight ear shaft rings 401 form a pair of two and are arrayed on the connecting shell 4, and the eight ear shaft rings 201 form a pair of two and are arrayed on the support ring 2, and a chain plate 3 is placed between each pair of ear shaft rings 401 and each pair of ear shaft rings 201, and the chain plate 3 and the pair of ear shaft rings 401 and the pair of ear shaft rings 201 are fixed together by bolts 301.
