It may include a chain portion 2600 for moving the position of the impeller-shaft support assembly 1000 by being positioned.

The lifting body portion 2100 may have a rod shape extending in the longitudinal direction.

The first lifting connection part 2200 may be formed to extend downward from a lower surface of one end of the lifting body part 2100.

For example, a hole through which the chain part 2600 can be caught may be formed in the first lifting connection part 2200.

The second lifting connection part 2300 may be formed to extend downward from the lower surface of the other end of the lifting body part 2100.

For example, a hole through which the chain part 2600 can be caught may be formed in the second lifting connection part 2300.

The third lifting connection part 2400 may be formed to extend upward from an upper surface of the middle portion of the lifting body part 2100.

For example, a hole through which the intermediate part 2500 can be caught may be formed in the third lifting connection part 2400.

The intermediate part 2500 is formed in a ring shape and is connected to the third lifting connection part 2400 and the crane, so that the third lifting connection part 2400 and the crane may be connected to each other.

The reason for using the intermediate part 2500 may be to utilize the lifting assembly 2000 regardless of the shape of various cranes.

In the lifting assembly 2000, a fourth lifting connection part 2700 and the lifting body part 2100 extending from one end of the lifting body part 2100 to face the first lifting connection part 2200 are tilted to one side. In order to prevent this, it may further include a balance chain part 2800 connected to the fourth lifting connection part 2700 and the crane.

In addition, the lifting assembly 2000 is a chain block part that is connected to the balance chain part 2800 to prevent the lifting body part 2100 from tilting to one side to adjust the length of the balance chain part 2800 (2900) may be further included.

The fourth lifting connection part 2700 may be formed to extend upward from an upper surface of the other end of the lifting body part 2100.

For example, a hole through which the balance chain part 2800 may be connected may be formed in the fourth lifting connection part 2700.

One end of the balance chain part 2800 may be connected to the crane, and the other end of the balance chain part 2800 may be connected to the fourth lifting connection part 2700.

Hereinafter, a process of transporting the impeller-shaft support assembly 1000 by the lifting assembly 2000 will be described in detail.

7 and 8 are views for explaining a process of transporting the impeller-shaft support assembly by the lifting assembly according to an embodiment of the present invention.

Referring to FIG. 7A, an operator may connect one chain part 2600 to the first lifting connection part 2200 and a shaft 1110 disposed on the other side of the impeller 1120.

Similarly, the operator may connect the other chain portion 2600 to the second lifting connection portion 2300 and the shaft 1110 disposed on one side of the impeller 1120.

At this time, the chain portion 2600 may not be taut.

Referring to FIG. 7B, the operator may position the lifting assembly 2000 in an upward direction to separate the impeller-shaft support assembly 1000 from the ground.

In this case, the lifting body 2100 and the impeller-shaft support assembly 1000 may be inclined in one direction.

In the present invention, the impeller-shaft support assembly 1000 may be inclined due to the weight of the temporary fixing parts 1271 and 1272, but is not limited thereto, and the structural change of the impeller-shaft support assembly 1000 Accordingly, the lifting body 2100 may be inclined to one side due to other causes.

Although not shown here, the shaft 1110 may have a shape such that the chain portion 2600 does not slip on the shaft 1110.

At this time, the balance chain portion 2800 may not be taut.

In this case, the tension of the balance chain portion 2800 may not act on one end of the lifting body portion 2100.

Referring to FIG. 8, an operator may wind the balance chain part 2800 by operating the chain block part 2900. (The balance chain portion 2800 may be wound inside the chain block portion 2900.)

Until the tension of the balance chain part 2800 is applied to one end of the lifting body part 2100 so that the lifting body part 2100 becomes horizontal, the chain block part 2900 is the balance chain part ( 2800) can be wound.

Through this method, the operator can stably position the impeller-shaft support assembly 1000.
