Description

BACKGROUND OF THE INVENTION 1. Apparatus for returning and method thereof

The present invention relates to a return device and method, and more particularly, to a return device and method capable of efficiently returning a heavy object deviated from the installation position to an accurate position.

In general, a cast iron manufactured in a steel mill performance factory is cut by a torch cutting machine (TCM), and then is drawn out to a roller table. The cast iron withdrawn to the roller table is transferred to a marking device by a transfer facility capable of transferring the cast steel in a direction crossing the roller table, and when a unique number is printed in the marking device, it is transferred to a subsequent process through a subsequent roller table.

Such a transfer facility may include a track table installed to extend in a direction crossing the roller table, and a cross transfer car that is movable along the top of the track table. The track table includes a track forming a moving path of the moving vehicle and a guide supporting the track, and the track may be installed so that at least a portion of the track is engaged with the guide so as to be movable on the guide in the moving direction of the moving vehicle.

However, a malfunction occurs due to various causes such as an operation system error, and a phenomenon in which the cast pieces cut by the cutting device are abnormally drawn out to the roller table often occurs. In this case, the cast iron pulled out to the roller table collides with the cast iron or the track seated in the moving vehicle, and an accident occurs in which the track is separated from the guide. When the track deviates from the guide in this way, it is necessary to stop the transfer of the cast and return the track quickly. However, since the track is a long and heavy weight, it is difficult to handle, and in particular, there is a problem in that it is difficult to engage the track in the correct position of the guide. Accordingly, since it takes a relatively long time to return the track, there is a problem that productivity is deteriorated because the casting process is not performed smoothly. In addition, since the operator is involved in all processes of returning the track, there is a problem that the operator is exposed to danger.

In the case where the cast piece S conveyed by the first roller table groups 110 and 110a is seated on the moving vehicle 240, the track 220 is raised in the same manner as described above, so that the first roller table group 110 The cast piece (S) seated on the 110a) may be seated on the moving vehicle 240. And even when the cast iron (S) is transferred using the moving car 240, the track 220 maintains an elevated state, and the upper surface of the track 220 or the upper surface of the moving car 240 is a roller table ( 111 to 118, 111a to 118a, 121 to 128) may be disposed at a higher position than the upper surface.

When the transfer of the cast piece (S) is completed by the moving car 240, the track 220 is lowered in the same manner as described above, so that the cast piece (S) on the upper part of the moving car 240 is transferred to the second roller table group 120. Can settle in.

In this way, the track 220 is seated on the guide 210 and may rise or fall while moving forward or backward in the second direction Y. However, as shown in Figure 1, when the track 220 is raised, when the cut slab S1 abnormally enters the first transfer unit 100, the abnormally entered slab S1 moves. (240) A phenomenon occurs in which the track 220 is separated from the guide 210 by colliding with the cast piece S or the track 220 seated on the upper part. The return device 300 is for returning the track 220 deviated from the guide 210 in this way, and combines a retractor 500 (see FIG. 9) provided on the upper part of the transfer facility, for example, a crane and a track 220 Can be used to make.

6 is an exploded perspective view showing a track support part of a track return device according to an embodiment of the present invention.

Referring to FIG. 6, the return device 300 is a track support part 300 connected to the track 220 so that it is fastened and detached from the retractor 500 provided on the top of the track 220, and at least a part thereof is rotatable. It may include.

The track support 300 may include a track support 310 and a fixing member 320 for connecting the track support 310 to the track 220.

The track support 310 may be formed in an approximately'T' shape, and the track support rod 312 extends in one direction, and the track support rod 312 extends in a direction crossing the track support rod 312. It may include a fastening rod 314 to be connected. At this time, the track support rod 312 can support the first track body 222 and the second track body 224 at the same time, the track support rod 312 is the first direction (X) or the track 220 It may be arranged so as to extend in the width direction of the track 220 while crossing the extending direction, for example, crossing the track 220.

The track support 310 should be able to sufficiently support the track 220 when returning the track 220. The track support 310 may be connected to the bottom of the track 220 so as to support the track 220 at the bottom of the track 220. Therefore, the length of the track support rod 312 connected to the track 220 is preferably formed to be at least longer than the length in the width direction of the track 220 (see FIG. 5B).

In addition, the fastening rod 314 is configured for direct connection with the retractor 500, and a fastener 316 may be formed at an end of the fastening rod 314 for connection with the retractor 500. At this time, the retractor 500 may include a retractor wire 520 to which the hook 510 is connected, and the fastening rod 314 may be connected to the hook 510. In addition, the fastening rod 314 is preferably connected to the center in the longitudinal direction of the track support rod 312 so that the track 220 can be stably traction using the retractor 500, and the track support rod 312 and It can be formed as a single structure. At this time, the fastening rod 314 has a length that can be easily connected to the hook 510 of the retractor 500, for example, at least a portion thereof is formed to be longer than the length that can be exposed to the top of the traveling rail 230 or the height of the track 220 As a result, at least a portion may be formed to have a length that can be exposed to the outside of the track 220. Here, an example in which one fastening rod 314 is connected to the track support rod 312 will be described, but if it does not affect the running rail 230, one or more, for example, two or more Three fastening rods 314 may be connected.

The track support 310 may be rotatably connected to the bottom of the track 220 using the fixing member 320. The fixing member 320 may include a bracket 322 in which an insertion hole 323 for inserting the track support rod 312 is formed, and a bolt 324 for fixing the bracket 322 to the track 220. have. At this time, the insertion hole 323 may be formed to have a diameter larger than the diameter of the track support rod 312 so that the track support rod 312 can rotate within the insertion hole 323. In this case, since the track support rod 312 can be separated from the insertion hole 323, a separation preventing member 326 may be connected to the end of the track support rod 312 in order to prevent the separation of the track support rod 312. have. In addition, when the hook 510 of the retractor 500 is connected to the track support 310, the operator directly or using a separate jig rotates the track support 310 to raise the fastening rod 314 in the vertical direction. Should be placed. In this case, since the track support rod 312 is rotatably connected to the fixing member 320, the track support 310 rotates within the insertion hole 323 of the fixing member 320 so that the fastening rod 314 is arranged. There is a problem that is difficult to maintain. Therefore, the track support rod 312 and the fixing member can adjust or limit the rotation range of the track support rod 312 so that the fastening rod 314 can maintain a good connection with the hook 510 of the retractor 500. You can also connect (320). For example, a rotation range adjustment member (not shown) such as an uneven structure may be formed on the outer circumferential surface of the track support rod 312 and the insertion hole 323 of the bracket 322 so that the track support rod 312 can rotate only within a certain angle.

I can.

Since the track support 310 is rotatably connected to the track 220, the track support 310 is rotated by the load of the fastening rod 314, so that the fastening rod 314 is exposed to the lower part of the track 220. I can. In this case, since the fastening rod 314 may cause a problem such as colliding with other facilities, the mounting frame 330 is installed on the track 220 so that the fastening rod 314 is mounted on the mounting frame 330. I can. The seating frame 330 may be installed in at least one of front and rear with respect to the moving direction of the moving vehicle 240. In this case, the seating frame 330 may be installed to be spaced apart from the track support rod 312, and a distance between the seating frame 330 and the track support rod 312 may be shorter than the length of the fastening rod 314.

When the track 220 is separated from the protrusion 214b of the guide roll 214 through this configuration, the track support 310 and the retractor 500 may be connected. That is, by rotating the track support 310 installed on the track 220 to raise the fastening rod 314, it is possible to connect the hook 510 of the retractor 500 to the fastening rod 314. Then, by operating the retractor 500 to raise the track 220, the track 220 is moved in the horizontal direction using the retractor 500 to move the guide grooves 222b and 224b of the track 220 to the guide roll ( It may be disposed on the protrusion 214b of 214). In this case, the guide grooves 222b and 224b and the protrusions 214b may be arranged side by side. Thereafter, the track 220 is lowered using the retractor 500 so that the guide grooves 222b and 224b and the protrusion 214b are engaged, so that the position of the track 220 can be returned to the original position.

A plurality of such return devices 300 may be provided in the length direction of the track 220. The track 220 is formed to extend in the moving direction of the moving vehicle 240 and may be supported by the guide 210 at a plurality of points. Accordingly, by providing a plurality of return devices 300, when the track 220 deviates from the specific guide 210, the track 220 can be efficiently returned to the original position at the corresponding position. For example, after dividing the track 220 into three sections in the moving direction of the moving vehicle 240, two return devices 300 are installed adjacent to each other for each section to install a total of six return devices 300. I can.

Meanwhile, in order to stably return the track 220, the retractor 500 and at least two or more return devices 300 may be connected using a separate fastening part 400.
