Description of the embodiments

The present utility model is further illustrated in the following drawings and detailed description, which are to be understood as being merely illustrative of the utility model and not limiting the scope of the utility model.

As shown in the figure, the tank body safety supporting device comprises a ring piston ring 1, a jack 2, a first upright post 3, a second upright post 4, a base plate 5, a stress plate 6 and a rib plate 7, wherein the ring piston ring 1 is horizontally fixed on a tank body 8 in a surrounding manner, the rib plate 7 is vertically fixed on the outer side of the ring piston ring 1, the stress plate 6 is horizontally fixed on the lower plane of the ring piston ring 1 and the rib plate 7, the first upright post 3 and the second upright post 4 are vertically arranged below the stress plate 6 side by side, the jack 2 is arranged between the stress plate and the first upright post 3, and the base plate 5 is arranged between the stress plate and the second upright post 4.

Taking VCM TK-601 ethylene tank maintenance of XX chemical plant as an example, the maintenance content is to dismantle the cold insulation material of the ethylene tank bottom and then replace, after the tank body and the tank bottom are cut and separated, a ring of [25a ring piston ring 1 is added on the outer wall plate of the tank body 8, a stress plate 6 is welded below the ring piston ring 1, 20 stand column supporting points are arranged in a ring as acting force support of a jack (the stand column is made of H-shaped steel), 20 jacks 2 are placed on the stand column one 3 to synchronously lift the stress plate 6 upwards, so that the tank body 8 starts to lift upwards from the ground, the lifting height measurement statistics is stopped once every five minutes, and whether the mechanical and tank bodies have abnormality or deformation is confirmed, the lifting height is synchronous and the lifting can be continued after no abnormality, when the lifting distance reaches 150mm (the regulated height), a stand column two 4 is filled with a backing plate 5, the backing plate 5 is connected with the backing plate 5 integrally by a mounting bolt, the jack is lowered, the backing plate 5 is removed, then a backing plate 135mm is also mounted below the jack, the jack is placed on the stand column one, the backing plate 135mm is lifted upwards, the lifting plate is always, the lifting cost is kept gradually high by the lifting distance of the stand column is kept by the method, and the lifting cost is kept by the stand column is high, and the lifting cost is always and the lifting cost is kept by the stand column is kept by the lifting height.

In order to prevent uneven stress of the stress plate 6 when the jack is lifted up and deviation of lifting distance of each jack, the utility model vertically welds two rib plates 7 at the outer side of the ring piston ring 1, and the vertical directions respectively correspond to the axes of the upright post I3 and the upright post II 4, so that the stress plate 6 can stably lift after being stressed.
