Left and right rocking cylinders 2b by connecting a bearing base 2h for swinging, a shaft base 2i to which the shaft 2e is attached, and one of the seating bases 2g and a left and right swinging cylinder 2b. Is composed of a handle 2j for moving the bearing base 2h during operation, and a hydraulic unit 2k for generating hydraulic pressure to operate the left and right swing cylinders 2b and the up and down swing cylinders 2c.

As shown in Fig. 5-1, the close-up position sensor 3 is a proximity limit switch which is attached to the upper surface of the traveling rail beam when the striker 3b attached to the lower end of the above-mentioned crane 12 comes close. (3a), a striker (3b) attached to the lower end of the crane (12) to operate the proximity limit switch (3a), and a confirmation lamp (3c) operated when the position is correct.

As shown in FIG. 5-2, the playing slag weight detector 4 weighs the slag 7 detected by the load cell 4a which detects the weight when the slag 7 is disposed in the slag port 6. It is made of a weight check indicator (4b) is installed in a place that is easy to check so that the operator can check.

In addition, the load cell 4a is provided between the shaft base 1i and the shock absorbing cylinder base 1j, as shown in Figs. 3 (3-1, 3-2).

As shown in Fig. 5-3, the trolley seating deck swinging panel 5 includes a rocking switch 5a for operating when the port trolley seating deck 2 swings, and a port trolley seating deck 2. It consists of a stop switch 5b which stops rocking, and 5c is a switch case.

Hereinafter, the operation of the present invention will be described in detail.

First, as shown in Fig. 6-1, the method of operating the loading dock seating deck 1, the loading dock position detector 3 and the playing slag weight detector 4 is carried out by the crane 12 carrying the finished ladle 11. If the striker 3b is matched with the proximity limit switch 3a attached to the overhead loading rail beam, the confirmation lamp 3c lights up.

At the same time, the hydraulic unit 1m which generated the hydraulic pressure to cause the slag port 6 to swing is stopped and the slag port 6 is stopped while the slag 7 is discharged. And, when the slag (7) discharging is completed, the weight of the slag (7) detected and excluded by the load cell (4a) appears in the weight digital display (b) the lower part number digital (B), and at the same time the upper number digital (A) slag The total slag weight in the port 6 is shown (where the shock absorbing cylinder 1k absorbs the shock and protects the device).

By the way, when the weight of the slag (7) discharged at this time comes out more than usual, the operator knows that the molten steel is mixed into the slag (7), and the slag port (6) is immediately taken out, and the slag (6) slag to the slag port (6) (7) is prevented from adhering and generating clumps (8).

On the other hand, when the crane 12 which has finished disposing the slag 7 moves and the striker 3b deviates from the proximity limit switch 3a (at this time, the confirmation lamp 3c goes out), it has been stopped. Baejang seating deck (1) will continue to swing again.

In addition, the operation sequence of rocking the mounting seat deck 1 is as shown in Figure 6 (6-1, 6-2), as follows.

First, the operation sequence for swinging the slag port 6 up and down is, as shown in Fig. 6-1, the hydraulic unit (1m) operation → the up and down movement cylinder (1c) up and down operation in the direction of the arrow (A) Up / down swing auxiliary bar (1f operation) → Then, the mounting table 1a is operated in the direction of the arrow → Therefore, the slag port 6 also swings in the direction of the arrow → At the same time, the contained slag 7 shake.

Second, the operation sequence for rocking the slag port 6 left and right is as shown in Fig. 6-2, the hydraulic unit (1m) operation → the left and right swing cylinder (1b) back and forth operation in the direction of the arrow (b) → bearing base (1h) Actuate in the direction of arrow (C) → Mounting stand (1a) Actuate in the direction of arrow (C) → Therefore, the slag port 6 also swings in the direction of the arrow (C) → At the same time, the contained slag 7 swings .

Therefore, the slag port 6 swings up and down and left and right repeatedly as described above, and prevents the slag 7 from sticking or the clogging 8 even if the discharging site is long.

And, the operation sequence for rocking the port bogie seating deck 2 is as follows, as shown in Fig. 7 (7-1, 7-2).

First, after starting the trolley | bogie 9, the oscillation switch 5a is operated.

First, the operation sequence for swinging the slag port 6 up and down is, as shown in Fig. 7-1, the hydraulic unit (2k) operation → up and down operation (2c) up and down operation in the direction of the arrow (D) (up and down, at the same time, Oscillation auxiliary bar (2f) actuation) → Then, actuate in the direction of arrow (d) in the mounting table (2a) → So, the slag port (6) also oscillates in the direction of the arrow (d) → At the same time, the contained slag (7) oscillates .

Second, the operation sequence for rocking the slag port 6 left and right is as shown in Fig. 7-2, the hydraulic unit (2k) operation → left and right swing cylinder (2b) back and forth operation in the direction of the arrow (e) → bearing base (2h) Operation in the direction of the arrow (bar) → Slag port (6) Swing in the direction of the arrow (bar) → At the same time, the contained slag (7) also swings.

And when the trolley | bogie 9 arrives at the slag yard length 10, the stop switch 5b is operated and the shaking of the port trolley mounting deck 2 is stopped.

Therefore, as described above, the slag port 6 repeatedly swings up and down and to the left and right, thereby preventing the slag 7 from sticking or generating the bump 8 during the movement of the trolley 9.

As mentioned above, although this invention was demonstrated by the limited embodiment and drawing, this invention is not limited by this, The person of ordinary skill in the art to which this invention belongs, Of course, various modifications and variations are possible within the scope of the claims to be described below.

According to the present invention, the slag port in which the slag is contained is allowed to swing until the slag yard is processed until the slag is processed, thereby preventing the slag from being entangled in the slag port or the occurrence of lumps, thereby reducing the processing time. Personnel and equipment inputs can achieve cost savings and worker accident prevention.
