It includes a clutch operating portion for selectively coupling the first clutch 830 and the second clutch 840 by forward or backward by using the air supplied from the first clutch 830.

The clutch actuator includes an air cylinder 862 having a cylinder rod cap 860.

A first discharge line 864 is installed at the rear end of the air cylinder 862, and a first auxiliary valve 866 is installed at the first discharge line 864. The first discharge line 864 and the air supply line 820 are connected by a first auxiliary line 868, and a second auxiliary valve 870 is installed in the first auxiliary line 868.

In this case, the first auxiliary line 870 is connected to the rear end of the air valve 822 along the air supply path on the air supply line 820.

Therefore, when the air valve 820 and the second auxiliary valve 870 are turned on while the first auxiliary valve 866 is turned off, air can be supplied to the rear end of the air cylinder 862.

In addition, a second discharge line 872 is installed at the front end of the air cylinder 862, and a third auxiliary valve 874 is installed at the second discharge line 872, and the second discharge line 872 and the air are provided. The supply line 820 is connected by the second auxiliary line 876, and the fourth auxiliary valve 878 is installed in the second auxiliary line 876.

In this case, the second auxiliary line 876 is connected to the front end of the air valve 822 along the air supply path on the air supply line 820.

Therefore, when the fourth auxiliary valve 878 is turned on while the third auxiliary valve 874 is turned off, air can be supplied to the front end of the air cylinder 862.

On the other hand, the first clutch 830 is installed on the drive shaft 812 of the air motor 810 as described above. In this case, the first clutch 830 is installed on the drive shaft 812 to rotate forward or backward on the drive shaft 812 while rotating together with the drive shaft 812.

Accordingly, the first clutch 830 advances on the drive shaft 812 while rotating together with the drive shaft 812, thereby engaging the second clutch 840 installed in the leveler reducer.

However, the first clutch 830 and the second clutch 840 should be formed in a shape that is engaged with each other for power transmission. Therefore, the first clutch 830 may not be easily coupled to the second clutch 840 while rotating.

Thus, in the exemplary embodiment of the present invention, the first roller 834 is installed at the teeth 832 of the first clutch 830, and the second clutch 840 at the portion at which the teeth 832 are coupled is provided. The first roller 834 forms a centering groove 842 to which the first roller 834 is coupled.

According to this configuration, even when the teeth 832 of the first clutch 830 is in contact with the teeth 844 of the second clutch 840, the first clutch 830 is smoothed by the first roller 834. As it rotates, it is engaged with the second clutch 840.

In this case, the air motor 810 is operated by the air supplied through the air supply line 820 to rotate the drive shaft 812 and the first clutch 830.

In addition, the air supplied through the air supply line 820 and the first auxiliary line 868 causes the cylinder rod cap 860 of the air cylinder 862 to advance, thereby supporting the supporter 890 and the first clutch. 830 is advanced toward the second clutch 840.

Accordingly, the first clutch 830 is coupled to the second clutch 840 according to the rotation and the forward operation of the first clutch 830, and then the rotational force of the drive shaft 812 is the first clutch 830. Since it is transmitted to the second clutch 840 through, it is possible to withdraw the leveler bar using the air motor 810.

When the leveler bar is drawn out of the coke oven according to the above action, the operator turns off the air valve 822, the second auxiliary valve 870 and the third auxiliary valve 874, while the first auxiliary valve 866 is turned off. And the fourth auxiliary valve 878 are turned on.

In this case, since the driving of the air motor 810 is stopped, the rotation of the driving shaft 812 and the first clutch 830 is stopped, and the cylinder rod is supplied by the air supplied through the second auxiliary line 876. Cap 860 is reversed.

Therefore, since the first clutch 830 is also reversed, the engagement of the first and second clutches 830 and 840 is released.

In the above description, the air valve 822 is turned off when the first and second clutches 830 and 840 are released. However, the air valve 822 is not necessarily turned off.

That is, it is also possible to reverse the first clutch 830 while rotating the drive shaft 812.

In addition, although the air valve 822 and the first to fourth auxiliary valves 866, 870, 874, 878 have been described as being manually operated by an operator, the valves may be configured to be automatically operated.

Although the present invention has been described in detail through specific embodiments, it is apparent that the present invention is not limited thereto and may be modified or improved by those skilled in the art within the technical spirit of the present invention.

As described above, the leveler system according to the exemplary embodiment of the present invention enables a quick emergency action by the worker alone, thereby reducing unnecessary time waiting for the support personnel to arrive.

Therefore, there is an effect that can prevent the complex equipment troubles caused by the delay of the action time.
