The lower end of the rack plate 113 is fixed to the roll 114 with a fixing plate 115, both sides are connected with a pin and a key and the key is assembled to the fixing plate 115 using a bolt.

The pinion shaft 119 penetrated in the center of the pinion 119a has a bevel gear 123 at the other end thereof, and has the other end while having a bevel gear engaged with the bevel gear 123 at a right angle. Edo bevel gear is configured to receive power transmission from the motor 126 through the shaft (122).

The bevel gear shaft 122 is connected to the bevel gear 125 perpendicular to the gear shaft 124 is installed at the shaft end, the gear shaft 124 is preferably assembled to the motor 126 by coupling.

The sensor bracket 128 is fixed to the upper portion of the rack plate 113 with a bolt.

Next, a description will be given of a stroker adjusting device unit for adjusting the height of the cutting device for removing the cutting snow by receiving the thickness value or the bending value measured from the bending measuring device unit.

A male thread is machined on the outer circumferential surface of the stroke adjustment rod 234 and a key groove is formed at the end of the shaft. A ball bearing is combined with the inside of the drive spur gear 237 and a female thread is machined therein. The ball bearings are bolted to the stationary plate.

7 is an operation flowchart of the bending state measuring unit of the cast steel according to the present invention, Figure 8 is an operation flowchart of the stroke control device according to the present invention.

As shown in FIG. 3, when the head portion 7 of the incoming cast steel is detected by the LIGHT BARRIER 133, the motor 126 rotates after the time designated by the timer, and the motor ( Bevel gear shaft 122 is rotated by the rotation of the gear shaft 124 connected to 126.

Then, when the bevel gear 123 connected to the bevel gear shaft 122 is rotated, the pinion 119a is rotated to engage the rack plate 113 engaged with it, the rack plate 113 When the roll 114 installed at the bottom reaches the upper surface of the cast piece 7 due to the fall of the electronic overcurrent (ELECTRONIC OVER CURRENT) is detected on the motor 126.                     

At this time, the motor 126 is immediately stopped, and the moving distance value of the sensing device by the motor rotation up to this time is measured by the PG (PULSE GENERATOR) 127 attached to the motor and transmitted to the stroker adjusting device.

If the rack plate 113 detects the falling stop limit switch 131 in a state where the slab does not detect the slab by continuing to descend, the motor 126 is stopped. The falling stop limit switch 131 is a sensor for preventing the damage of the rack plate 113 due to a malfunction of the light barrier 133.

Thereafter, the motor 126 again rotates in reverse, and the pinion 119a rotates in accordance with the rotation of the motor 126 so that the rack plate 113 rises.

When the slow limit switch 130 is detected by the sensor bracket 128 installed on the top of the lecks 113, the motor 126 rotates at a slow speed and stops when the stop limit switch 129 is detected.

The rack plate 113 is always waiting at the position of the stop limit switch 129, the bending detection of the tail portion of the cast is made due to the detection of the free signal (FREE SIGNAL) of the light berries 133, the operation sequence of the head portion Same as when detected.

Referring to the operation of the stroker adjustment unit as shown in Figure 5, through the above process, the bending measurement value of the slab (or the thickness value of the typical slab in the case where the bending is not large) from the slab bending measuring unit portion When receiving, the motor 226 is in a rotational movement, by the rotation of the pinion gear 219 connected to the motor 226, the rack plate 245 connected to one end of the guide rod 244 for adjusting the stroke The linear movement of the forward movement of the guide rod 244 for adjusting the stroke is also a straight forward movement.

At this time, the stroke control rod 234 is rotated by the rotational movement of the drive spur gear 237 engaged with the rakes 213 installed at the four side ends of the guide rod 244 for adjusting the stroke. Will be adjusted up and down.

The stroke control rod 234 is configured in such a way that two right screws and two left screws are installed, the movement distance of the stroker adjustment rod 234 installed at four places during the forward and backward linear movement of the guide rod 244 for adjusting the stroke The values always match and the up and down adjustments are made.

The travel distance value of the stroke adjustment rod 234 is counted by the PG 227 connected to the motor 226.

On the other hand, when the sensor bracket 228 installed on the stroke adjustment guide rod 234 detects the stop limit switch 229, the motor 226 is stopped.

When the cutting of the head portion of the cast piece 7 is completed, the motor 226 rotates in reverse, and when the sensor bracket 228 detects the slow limit switch 229, the motor 226 rotates at a slow speed. It stops when the stop limit switch 231 is detected.

On the other hand, the cutting tongue removal of the tail portion of the cast 7 is performed in the same manner as the cutting tongue removal of the head portion.

The apparatus for adjusting the stroke of the present invention as described above has a bending state measuring unit for measuring the thickness of the cast steel or the generated bending value, and uses the value measured therefrom to determine the position of the stroker in the stroker adjusting unit. When adjusting, the adjustment position is corrected to be the optimum position for removing the cutting tongue, and the bending value is measured on the cast steel under any conditions, and the cutting tongue can be removed with the stroke corrected to the optimum position. It provides the effect that can operate the equipment condition more stably by preventing.
