At one end, a bolt hole 282 penetrating the body 281 is formed, and a long hole 283 formed along the longitudinal direction of the body 281 is formed at a predetermined distance from the bolt hole 282. It is characterized by.

On the other hand, the bolt holes on both sides of the secondary band 252-2b and the reinforcement plate 252-10 of the foot brake 252 to correspond to the bolt hole 282 and the long hole 283 of the fastening member 280 ( (Not shown).

As a fastening method, after the bolt hole 282 of the fastening member 280 is matched with the bolt hole of the secondary band 252-2b, a fastening member 280 is centered on the bolt by inserting a bolt (not shown). Tighten enough to rotate about the axis.

Next, the fastening member 280 is rotated so that the long hole 283 matches the bolt hole formed on the reinforcing plate 252-10, and then the bolt is also inserted to tightly tighten the bolt so as not to turn.

Finally, when the bolt inserted into the secondary band 252b is completely tightened through the bolt hole 282 of the fastening member 280, the secondary band 252b and the reinforcing plate 252-10 due to the fastening member 280 ) Is to form a solid connection relationship.

In particular, the long hole 283 in the fastening member 280 becomes a main shape to match the bolt hole of the reinforcing plate 252-10.

That is, a bolt hole is formed in the secondary band 252b in a flat state, but when the fastening is performed, the secondary band 252b is bent and fastened to surround the main shaft 230, and thus the bolt hole and the reinforcement plate formed in the secondary band 252b are formed. It is to eliminate the error for the minute difference in distance from the bolt hole formed in (252-10).

Preferably, when the bolt is fastened using a washer to the long hole 283, a more robust fastening relationship can be obtained.

In addition, the corner portion of the body 281 is caused by fastening in a state where the fastening member 280 is rotated by chamfering the corner portion of the body 281 in which the bolt hole 282 of the fastening member 280 is formed in a circular shape. The primary band 282a is prevented from being passed to the side.

This will be effective to prevent this, because the operator may be injured by the edge portion of the fastening member 280.

Accordingly, when the primary band 252a made of synthetic resin is worn out, the operation for replacing it can be performed very easily.

Due to the combination as described above, the welding operation performed as a means for fixing between the secondary band 252b and the flange 252-3 is not an essential operation, so assembling and disassembly are easy, so the efficiency of operation is doubled. You can expect.

In addition, if the hand brake 251 is grafted in the same manner, assembly and disassembly may be more efficient.

However, in order for the band 252-2 of the flat shape to wrap around the main shaft 230, it must be kept in a circularly dried state, and the reinforcing plate 252-10 and the band 252-2 in contact with the band 252-2 in a circular state are in contact with each other. Since one surface of the two pivot pins 252-8 should also be formed to be curved, for convenience of operation, the band 252-2 and the reinforcing plate 252-10 and the band 252-2 and the second pivot pin ( In order to assemble 252-8), since the band 252-2 must be continuously rolled in a circular shape, the structure of the band 252-2 can be changed and manufactured as follows.

16 is a front schematic view of a band according to another embodiment in a clutch structure of an index wall-integrated water gate device comprising a hydraulic water gate driven by the present invention hydraulically and a hydraulic water gate of a double watertight structure, and FIG. 17 is driven by the present invention hydraulically. It is a plan view of a band according to another embodiment in a lifting device of an integrated hydrostatic water gate device consisting of a hydraulic water gate and a hydraulic water gate of a double watertight structure.

16 to 17, the secondary band 252-2b is directly on one surface of the secondary band 252-2b which is in direct contact with the reinforcing plate 252-10 and the second pivot pin 252-8. ) To form a T-shaped projection (252-2c) along the longitudinal direction, also on one surface of the reinforcing plate (252-10) and the second pivot pin (252-8) contacting the secondary band (252-2b) A long groove (not shown) corresponding to the T-shaped protrusion 252-2c is formed to form a T-shaped protrusion 252-2c formed in the secondary band 252-2b before assembly of the fastening member 280. When inserted into the long groove formed in the reinforcing plate 252-10 and the second rotating pin 252-8, the band 252-2, the reinforcing plate 252-10, and the second rotating pin 252-8 Is fixed as if they are in contact with each other, so that the bolting operation due to the fastening member 280 can be more easily performed.

In addition, the T-shaped protrusion 252-2c also serves as a rib to prevent the band 252-2 from being twisted to the left and right to deform.

The present invention is composed of a hydraulic water gate and an automatic water gate with an integrated water gate, so the construction of the hydraulic water gate is less expensive because the hydraulic water gate is additionally installed without breaking the existing water gate device with an integrated automatic water gate. The watertight effect due to the installed sluice is excellent, and there is also a remarkable effect of preventing backflow due to the automatic sluice.
