DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scaffold installed in a beverage tank for storing beer, soft drinks, and the like when working inside the tank, and is particularly effective when used in a conical tank. .

[0002]

2. Description of the Related Art FIGS. 30 to 32 show conventional scaffolds installed in a beverage tank for storing beer, soft drinks, and the like when working inside the beverage tank. As shown in FIG. 30, the beverage tank 1 includes an upper straight body 2, a lower straight body 3, and a conical portion 4, and is connected by a horizontal joint 5.

On the other hand, as shown in FIGS.
00 is a bracket 101, a single tube 102, and a scaffold plate 1
03, lashing 104, and handrail 105, the member is carried into the beverage tank 1 using a ladder 110 provided in the manhole 4a below the conical portion 4 of the beverage tank 1, and assembled inside the beverage tank 1. I have to.

1 is a framework scaffold, and 112 is a rolling tower.

[0005]

A scaffold 1 as described above.
00 is installed inside the beverage tank 1,
There were the following problems.

Since the above-mentioned member is carried in from the manhole 4a of the conical portion 4 of the beverage tank 1, the short single tube 1
Since 02 must be used, the number of parts becomes very large, and assembling and disassembly take a lot of trouble.

Work (for example, buffing work) on the inner peripheral surface portion (several tens) of the beverage tank 1 that comes into contact with the single pipe 102
Therefore, when the scaffold 100 is dismantled, the above work must be performed while dismantling the scaffold 100, and the work efficiency is extremely poor.

The inner peripheral surface of the beverage tank 1 that comes into contact with the single pipe 102 is damaged by the contact with the single pipe 102, and therefore must be repaired when the scaffold 100 is disassembled. I had to.

When the rotary table 20 is rotated, the supporting columns 30 and 40 move smoothly with respect to the inner peripheral surface of the conical portion 4 via the rollers 36 and 46, so that the above-described operation can be easily performed on the above-mentioned portions. Can be applied to

After completing various operations on the inner peripheral surface of the beverage tank 1 in this way, the beverage tank 1 is disassembled in the reverse order and carried out from the inside of the tank 1. At the time of carrying out, the portion that has contacted the inner peripheral surface of the beverage tank 1 is
Since only the rollers 36 and 46 are used, there is no possibility that the inner peripheral surface of the beverage tank 1 is damaged.
Only dismantling work can be performed without performing repair work.

Therefore, according to such a scaffold for a beverage tank, the following effects can be obtained. Assembly and disassembly can be performed efficiently. Since there is no work impossible part due to the presence of the scaffold, work efficiency can be greatly improved. Since the inner peripheral surface of the beverage tank 1 is not damaged, it is not necessary to repair the scaffold when dismantling the scaffold, and the working efficiency can be greatly improved.
