DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Circular blade transfer jig of the present invention includes a base body member 10 having a connecting ring 14 connected to the crane. The base body member 10 has a first side portion 11 and a second side portion 12 spaced apart so that the standing circular blade 1 is inserted.

The first side portion 11 and the second side portion 12 are formed at positions corresponding to each other, that is, straight through-holes 10a. The pin through hole 10a is provided with a locking portion 21 protruding to an outer circumferential surface at one end thereof, and a fixing pin member 20 through which the fixing hole 22 is drilled at the other end thereof.

The fixed pin member 20 penetrates through the first side portion 11 and the second side portion 12, and has a circular blade 1 inserted between the first side portion 11 and the second side portion 12. Penetrates.

The circular blade (1) is an example of a large circular blade (1) mounted on a cutting machine for cutting the front and rear ends of the section steel manufactured through a rolling process, and includes other uses in addition to the section steel cutter.

At the rotation center of the circular blade 1, a mounting hole 1a for rotatably mounting the circular blade 1 is formed in a semi-circular blade cover (not shown), and is spaced apart from the mounting hole 1a. The dragon hole 1b is drilled.

The fixing pin member 20 penetrates the feed hole 1b of the circular blade 1.

In addition, the present invention includes a locking pin member 30 that is inserted into the fixing hole 22 of the fixing pin member 20. The locking pin member 30 is provided on one side of the first side portion 11 and the second side portion 12 of the base body member 10, and among the first side portion 11 and the second side portion 12. It is inserted into the fixing hole 22 on the other end side of the fixing pin member 20 protruding to one side.

In addition, the base body member 10 is mounted on one side of the first side portion 11 and the second side portion 12, and pin guide hole 13a through which the locking pin member 30 penetrates up and down. The drilled pin guide portion 13 is included.

The pin guide 13 may move the locking pin member 30 up and down at a predetermined position so that the locking pin member 30 can be easily coupled to the fixing hole 22 of the fixing pin member 20. To be.

The present invention further includes a locking handle member 40 connected to the locking pin member 30, and one end of the locking handle member 40 is located at an upper side of the pin guide part 13. It is connected to the portion of the member 30, the other end of the locking handle member 40 is connected to the portion of the locking pin member 30 located on the lower side of the pin guide portion (13).

The locking handle member 40 is caught by the pin guide portion 13 so that the locking pin member 30 does not fall out of the pin guide portion 13 and is formed to be gripped by the user so that the locking pin member 30 ) Can be easily inserted into and withdrawn from the fixing hole 22.

The circular blade 1 is inserted between the first side portion 11 and the second side portion 12 during transport as shown in FIG. 2. In addition, the fixing pin member 20 has the first side portion 11, the second side portion 12, such that the other end side on which the fixing hole 22 is formed protrudes to the side where the pin guide portion 13 is provided. It penetrates the circular blade 1. In addition, the locking pin member 30 passes through the fixing hole 22 of the fixing pin member 20 to support the fixing pin member 20 so as not to be released from an external impact.

That is, the fixing pin member 20 is externally transferred during the circular blade 1 by the locking pin member 30 penetrated through the locking portion 21 formed at one end side and the fixing hole 22 formed at the other end side. It is firmly fixed without being hit by the impact.

Therefore, it is possible to prevent the accident that the circular blade 1 falls while the fixing pin member 20 is removed during the circular blade (1) transfer.

On the other hand, the present invention is a circular blade transfer jig is provided between the first side portion 11 and the second side portion 12, the first pressing plate member 50 and the second pressing plate member capable of mutually adjusting the gap. 60;
