Description

Inner and outer container sleeving tool for double-layer tank

Technical Field

The utility model relates to assembly of a double-layer tank, in particular to a tool for sleeving an inner container and an outer container of the double-layer tank.

Background

A double tank comprising: the outer container phi 6400 multiplied by 14, the inner container phi 5800 multiplied by 26, the inner surface of the outer container is provided with 5 rings of inner reinforcing ring T-shaped steel (the thickness is 18 mm); the weight of the container is about 50 tons, the inner surface and the outer surface are finally connected through 12 glass fiber reinforced plastic radial supports, the sheathing process is the most difficult in the whole assembly process, and special tools are required to be designed.

The problems are that:

outer vessel barrel dimensions (excluding closure): ID6372 multiplied by 14 multiplied by 6842, because the wall thickness is thinner, the inner wall is reinforced by 5 rings of reinforcing rings; inner container dimensions (including head): ID5800×35/34/26× 8544, weighing 50 tons, and having a piping system attached to the outer wall; after the reinforcing ring is welded in the outer container, the gap between the inner cylinder and the reinforcing ring is about 91mm under the condition that the inner cylinder and the outer cylinder are concentric. The difficulty is that the inner container and the accessory cannot contact the outer container reinforcing ring when the inner and outer containers are sleeved, otherwise the parts of the inner container are damaged, or the T-shaped reinforcing ring of the outer container is deformed. The existing sleeving tool usually controls the direction of the inner container to enter the outer container by manually holding the inner container after lifting the inner container in a row, which leads to inaccurate control and damage to components. There are also factories that use concentric shafts that cover the inner container and then cover the inner container in the outer container, and then control the movement of the shaft to cover the inner container in the outer container.

In view of the design of the tooling to take into account operability, safety and load carrying capacity, it is desirable to provide a safe and effective nesting tooling.
