The lower flanges of the H-beams or I-beams 12 are provided with first and second inversion driving units 20a, 20b.

As shown in FIGS. 3 and 4, the first inversion driving unit 20a includes a block 37 fixed to one edge of the lower flange and a motor installed at one side of the block 37 to be driven by hydraulic or pneumatic pressure. And a worm gear 27 including a worm screw 25 that rotates by the rotational force transmitted from the motor 14 and a worm gear 27 that rotates by the linear rotation of the worm screw 25. ) And a first roller block (29) installed on the side of the worm gear (27).

The block 37 includes a first clamp block 35 installed on the upper surface of the lower flange by a first screw 38 and first and second vertical plates 48a fixed to the first clamp block 35 so as to face each other. , 48b). Each of the first and second vertical plates 48a, 48b is fixed to the edge of the first clamp block 35 by a second screw 39.

The drive unit is installed in the first vertical plate 48a. That is, the motor 14 of the drive part is installed in the first vertical plate 48a of the block 37 by the third screw 36. The motor 14 is driven and rotated by the hydraulic or pneumatic pressure discharged from the nozzle 33 connected to the hydraulic or pneumatic unit (not shown). Accordingly, the rotational force of the motor 14 is transmitted to the worm screw 25.

The worm screw 25 receives a rotational force to the motor 14. To this end, one side of the worm screw 25 is connected to the rotating shaft of the motor 14 through the housing 34. First and second oil seals 60 and 61 are installed at edges of the worm screw 25, and a roller bearing 65 is installed between the first oil seal 60 and the housing 34. In addition, a second oil seal 61, a first ball bearing 64, and a fastening nut 63 are installed at the other end of the worm screw 25 and surrounded by the flange 66.

In addition, the worm gear 27 is installed on the side surface of the first roller block 29 by the fourth and fifth screws 43 and 44.

Accordingly, the first roller block 29 is rotated by the rotational force transmitted from the drive shaft 22. The central portion of the first roller block 29 is formed with a triangular groove having a predetermined depth, and a groove having a predetermined depth is formed at an inclined portion of the groove. The first sealing belt 24a is applied to the groove. Here, the reason for forming the groove in the first roller block 29 and the inclined form is to improve the frictional force with the first sealing belt 24a.

As described above, when the motor 14 rotates by the hydraulic pressure or the pneumatic pressure, the first reverse driving unit 20a transmits the rotational force of the motor 14 to the worm screw 25 so that the worm screw 25 rotates. As the worm screw 25 rotates, the worm gear 27 engaged with the worm screw 25 at right angles rotates, and as the worm gear 27 rotates, the drive shaft 22 rotates so that the first roller block is rotated. Rotate (29). That is, the motor 14 rotates the first roller block 29 through the worm screw 25, the worm gear 27, and the drive shaft 22.

As shown in FIG. 5, the second inversion driving unit 20b includes a block 67 fixed to the other end edge of the lower flange and a second roller block 69 inserted into the drive shaft 22 and installed in the block 67. ).

The second roller block 69 is provided between the third and fourth vertical plates 78a and 78b of the block 37. At this time, a fourth ball bearing 57 is installed between one side edge of the second roller block 69 and the third vertical plate 78a, and an opposite side edge of the second roller block 69 and the fourth vertical plate ( The fifth ball bearing 56 is installed between the 78b). The second roller block 69 is fixed to the drive shaft 22 by at least two or more ninth screws 51.

Accordingly, the second roller block 69 is rotated by the rotational force transmitted from the drive shaft 22. In the center of the second roller block 69, a triangular groove having a predetermined depth is formed, and a groove having a predetermined depth is formed in the inclined portion of the groove. The second sealing belt 24b is placed on the groove. Here, the reason for forming the groove in the second roller block 69 and to be inclined is to improve the frictional force with the second sealing belt 24b.

In addition, a balance block 68 is provided in the second inversion driving unit 20b to balance the weight with the first inversion driving unit 20a.

When the motor 14 rotates by the hydraulic or pneumatic pressure of the second inversion driving unit 20b, the motor 14 rotates the drive shaft 22 as the worm screw 25 and the worm gear 27 rotate. As a result, the second roller block 69 provided at the other end of the drive shaft 22 is rotated.

As such, the first and second inversion driving units 20a and 20b are transported along the lower flange of the H-beam or I-beam 12 according to the length of the workpiece 18. At this time, the maximum transfer distance of the first and second inversion driving units 20a and 20b is about 1/4 of the total length of the H-beam or I-beam 12.
