Description

[Detailed explanation of the idea] The present invention relates to improvements in saddles for heat exchangers and the like.

Long-bodied equipment such as heat exchangers and horizontal receivers, including condensers, which are widely used in chemical plants and oil refineries, are supported horizontally by fixing them to concrete foundations. on top of the base plate
This is accomplished by bolting a welded cross-section or H-shaped steel saddle support to the bottom of the device.

It depends on the layout of the plant, but in most cases 2
Books, or sometimes three or more, are arranged one above the other, also with intermediate saddles in between.

These devices must be inspected not only when there is an abnormality, but also periodically, and maintenance such as replacing gaskets, removing scale, and repairing valves is required.

Scaffolding needs to be erected for this work, but in the past, scaffolding was prepared by tying together scaffolding materials such as logs and steel pipe scaffolding to form a tower next to these devices.

Therefore, in order to create a strong and safe scaffold, it is necessary to carry out a very serious assembly process, which not only takes up the surrounding passageways, but also involves complicated work of fabricating, assembling, and disassembling the scaffolding.

Moreover, since the maintenance work for the heat exchanger changes all at once, for example, first by removing the channels and then by removing the tube bundles, the scaffolding must also be changed accordingly, making the above problem even more serious.

The solution proposed by the present inventor is to provide a means for fixing a working scaffold in advance at an appropriate location on the saddle of the heat exchanger, and to construct the scaffold around the saddle. .

The scaffold fixing means of the present invention, as shown in FIG. 1, provides an appropriate number of through holes 12 in the saddle supports 1 to 1, and fixes the scaffolding material 4 with a fixture 5 through these holes.

In Figure 1, 2 is a heat exchanger and 3 is a foundation concrete platform.

In detail, as shown in FIG. 2, U-bolts 14 are used as fixtures 5 to attach scaffolding material 4 such as steel pipes.

By adopting the configuration described above, the scaffolding becomes stable,
Work can be done safely.

In particular, a stable condition can be maintained even if part of the scaffolding is removed as work progresses.

(For example, even if you remove the part fixed to the upper intermediate saddle, the part fixed to the lower saddle will not be affected.

) Scaffolding can be easily assembled using fewer scaffolding materials than before, so the number of passages occupied by the scaffolding is reduced accordingly, and disassembly and removal is also easy.
