Detailed Description
In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
The detailed structure of the present invention will be further described with reference to the accompanying drawings and the detailed description.
Referring to fig. 1, a marine tank body cylinder roundness correction tool mainly includes a first hoop 1 and a second hoop 2. The inner diameters of the first embracing ring 1 and the second embracing ring 2 are both standard semi-circular arc surfaces, and after the first embracing ring 1 and the second embracing ring 2 are folded from two sides, the inner surfaces of the first embracing ring 1 and the second embracing ring 2 form a 365-degree complete circular arc.
The two flat gaskets 3 are respectively welded on the inner and outer surfaces of the end part of the left side of the second holding ring 2, the upper part of each flat gasket 3 is provided with a gasket hole 3a, and the circle center of each gasket hole 3a, the right side end part of the second holding ring 2, and the circle center space after the first holding ring 1 and the second holding ring 2 are folded are all located on the same straight line.
The mounting hole 1a is opened on the left end of the first embracing ring 1, and when the first embracing ring 1 and the second embracing ring 2 are closed from two sides, the bolt 4 respectively penetrates through the two gasket holes 3a and the mounting hole 1a from one side, so that the left end of the first embracing ring 1 is fixed on the left end of the second embracing ring 2.
The first embracing hoop abutting protrusion 1a is arranged on the outer side of the right end part of the first embracing hoop 1, and the upper surface of the first embracing hoop abutting protrusion is a horizontal first embracing hoop abutting surface 1 aa. The second embracing hoop top tight bulge 2a is in a reverse 7-shaped shape and is arranged at the right side end part of the second embracing hoop 2, the lower part of the second embracing hoop is provided with a linear extension arm 2ab, and the extension arm 2ab is vertical to a straight line formed by connecting the circle center of the gasket hole 3a, the right side end part of the second embracing hoop 2, the closed circle center of the first embracing hoop 1 and the closed circle center of the second embracing hoop 2. The second embracing top tight face 2aa is arranged on the right side of the second embracing top tight bulge 2a, the surface of the second embracing top tight face 2aa is perpendicular to the extension wall 2ab and is parallel to the first embracing top tight face 1 aa.
