Description

[Detailed Description of the Invention] The present invention relates to a mobile cooling bed that connects the rolling process and the finishing process of steel materials, and particularly relates to a divided mobile cooling bed that improves the effective utilization of the floor surface during cooling.

In the manufacturing process of long steel, as shown in Figure 1, steel material a that has been rolled into a shape by rolling line b is sent to finishing line f where it is cut, straightened, cooled, etc. A moving cooling bed d is arranged between the entry table C at the end and the delivery table of the finishing line to connect both lines.

This moving cooling bed transports materials using various transport methods such as a walking beam type and a chain conveyor type, and since there is a difference between the working efficiency of a rolling line and that of a finishing line, It is provided to buffer this and connect both processes, and in the case of large-scale equipment, it can reach up to 30 m in width and 50 m in length.

As mentioned above, since this cooling bed connects two work processes with different material transfer speeds, empty areas with no material placed on the cooling bed occur due to the difference in processing capacity of each line.

However, with conventional moving floors, the entire large floor surface performs the same transfer operation as one, so operation continues with empty areas created, and the effective occupancy rate of the floor surface during work operations is low. It was low.

The purpose of the present invention is to eliminate these drawbacks of the conventional walking beam type cooling bed, and to provide a divided type moving cooling bed that makes effective use of the floor surface.

Originally, the walking beam transfer mechanism used a combination of a lift mechanism and a dowel rubber mechanism to make a movable frame perform a rectangular movement, and by making the movable frame cooperate with a fixed frame, it could intermittently move the material on the fixed frame. It is meant to be moved.

The movable frame is composed of an elevating frame included in the lift mechanism and a horizontal movement frame included in the traverse mechanism.

As shown in FIG. 2, the lift mechanism 1 includes a swinging lever 12, a drive device for the swinging lever 12, a lifting frame 11 connected to the upper end of the swinging lever 12, and both ends of the lifting frame 11. Inclined body 1 provided at the bottom and having a sloped surface
3, and a roller 14 that rotatably abuts on the inclined body 13.

The traverse mechanism 2 also includes a horizontally moving frame 21 placed on the lifting frame 11 via rotatable rollers.
, a lever mechanism 22 that is connected to the horizontally moving frame 21 and swings within a certain range in order to move the horizontally moving frame horizontally, and a driving device for the lever mechanism 22.

In the present invention, the cooling bed is divided into two at the middle part in the transfer direction, and both the lifting frame 11 and the horizontal movement frame 21 are divided at the middle dividing point, and the downstream side (finishing line side) and the horizontal moving frame 21 are divided into two parts. The upstream side (rolling line side) A is separate from the upstream side (rolling line side) so that independent transfer movements or pauses can be performed without relation to each other.

Further, only the horizontal movement frame 21 has its separated parts extended, an overlapping part is provided as shown in FIG. The downstream side B is also integrated so that it can perform an integrated operation similar to a conventional moving bed.

In the moving cooling bed of the present invention, it is possible to selectively divide the bed into two parts in the middle or operate the whole bed as one unit.

As shown in Fig. 4a, if material a is placed only on the downstream side B and there is an empty area on the upstream side A, the cooling bed is divided by removing pin 3 at the intermediate dividing point. .

Next, as shown in FIG. 4b, the lower end of the swinging lever 12 on the upstream side is moved to the left by a drive device such as an electric motor or a hydraulic cylinder, and the lifting frame 11 connected to the upper end of the swinging lever 12 is moved to the downstream side. Push towards B.

At this time, the inclined body 13 provided on the lower surface of the elevating frame 11
Due to the cooperative action of the inclined surface and the rollers 14, the elevating frame 11 moves toward the downstream side B and simultaneously rises, lifting the horizontally moving frame 21.

In the state shown in FIG. 4a, the upper surface of the horizontally movable frame 21 is located slightly below the upper surface of the fixed frame 4, so the material a is supported on the fixed frame 4.
In the state shown in figure b, the horizontally moving frame 21 is the fixed frame 4.
is lifted above to support material a.

In addition, since the horizontally moving frame 21 is placed on the elevating frame 11 via rollers, the horizontally moving frame 21
1 remains unchanged between FIG. 4a and FIG. 4b.

Next, as shown in FIG. 4C, the lever mechanism 22 on the upstream side A
By moving the lower end of the lever mechanism 22 upward by the drive device, the horizontal movement frame 21 connected to the upper end of the lever mechanism 22 is moved a certain distance toward the downstream side B while carrying the material a.

Next, as shown in FIG. 4d, move the lower end of the swing lever 12 to the right.

Then, the elevating frame 11 descends and returns to the upstream side A.

The horizontally moving frame 21 only moves downward, but does not move horizontally.

At this point, the top surface of the horizontally moving frame 21 is positioned below the top surface of the fixed frame 4, so that the material a is again supported on the fixed frame 4, but in a more downstream position than in FIG. 4a. It is being advanced towards side B.

Finally, as shown in FIG. 4e, by moving the lower end of the lever mechanism 22 downward, the horizontal movement frame 21 is moved to the upstream side A.
Return to the direction.

In this way, the elevating frame 11 and the horizontally moving frame 2
1 cycle of rectangular movement of the movable frame is completed.

During this operation, the lift mechanism 1' and the traverse mechanism 2' on the downstream side B remain inactive from beginning to end, so by repeating the operations shown in Figures 4a to 4e, the material a is successively moved to the floor surface on the upstream side A. Finally, the entire floor surface is filled with material a, as shown in Fig. 4f.

At this point, the horizontally moving frame on the upstream side A and the horizontally moving frame on the downstream side B are connected by pins 3, and the entire cooling bed is operated in conjunction.

As a result, there is no longer any empty area on the cooling bed surface, and the space becomes occupied with a high effective occupancy rate.

Note that the operation of connecting and disconnecting the cooling bed may be performed from a separated position using a mechanical clutch or the like instead of using a pin.

According to the split-type mobile cooling bed of the present invention, the effective occupation rate of the floor surface in a large cooling bed can be significantly improved, thereby improving the operability of the line and greatly contributing to cost reduction.
