Description

[Detailed description of the invention] This invention involves placing a large number of manbos, such as steel materials such as bloom beam blanks or heat-resistant bricks, as spacers on the top surface of the slag when heating slag for light blooming in a blooming and soaking furnace. This invention relates to a spacer placement device between steel pieces.

When heating slabs for light blooming in a blooming soaking furnace,
In order to increase the heat transfer efficiency of each slab, it was necessary to arrange a large number of manbos as spacers between the slabs to provide appropriate gaps.

Therefore, conventionally, as shown in FIG. 1, a forklift type brick setting machine 51 is used to place heat-resistant bricks 53 as a mambo on the upper surface of a slab 52, and then a crane (not shown) is used to divide the slab 52 into equal parts. It was to be placed in a heat furnace (not shown). In FIG. 1, 51 is a forklift brick setting machine, 54 is a forklift, 55 is a brick set, 52 is a slab, and 56 is a rental vehicle.

The procedure for placing the heat-resistant bricks 53 on the upper surface of the slab 52 using the conventional forklift type brick setting machine 51 is as shown in Figures 2-a, b, c, d, and e. 57 is opened and closed using hydraulic pressure and a spring, and the second-stage heat-resistant bricks 58b are similarly locked in stages using hydraulic pressure and a spring, so that the heat-resistant bricks are successively placed on the slab.

That is, as shown in FIG. 2-a, the brick set 55 is first lowered and stopped on the slab 52. At this time, the first stage heat-resistant brick receiver 57 is in a closed state, but the second stage heat-resistant brick 58b is not yet locked. Next, as shown in Figure 2-b, after locking the second stage heat-resistant brick 58b, the first
The tier heat-resistant brick receiver 57 is opened, and the first tier heat-resistant brick 58b is placed on the slab 52.
Next, the brick set 55 is raised as shown in FIG. 2-c. Next, as shown in Figure 2-d, after the first stage heat-resistant brick receiver 57 is closed, the second
The lock of the step heat-resistant brick 58b is released. As a result, each of the heat-resistant bricks 58b, 58c, and 58d is successively lowered by one step. Next, the brick set 55 is lowered as shown in FIG. 2-e. Heat-resistant bricks are placed on the slab 52 by repeating these steps one after another.

As mentioned above, conventionally, heat-resistant bricks were placed on slabs using a forklift type brick setting machine, but when placing heat-resistant bricks on top of slabs loaded more than ten times on a rental vehicle platform, it took a long time. In addition to having to use a large-capacity forklift type brick setting machine, the placing position of the heat-resistant bricks must be visually confirmed, which makes the placing work inefficient, especially when it comes to the vertical and horizontal widths of the slab. Accordingly, it becomes difficult to place the heat-resistant bricks, and furthermore, the mechanism of the brick set for placing the heat-resistant bricks is complex and tends to malfunction, and maintenance costs are high.

The present invention eliminates the drawbacks of the conventional methods as described above, and makes it possible to easily adjust the placement position of the spacer placed on the slab, and improve the efficiency of the placement work through automation. The object of the present invention is to provide a spacer mounting device between steel pieces.

That is, in the present invention, a column is erected on a movable cart, and an arm that can move up and down, the tip of which protrudes horizontally from the column, and the rear end of which slides along the column. A support beam A is provided at the tip of the arm and is perpendicular to and horizontal to the arm, and a plurality of support beams B are suspended perpendicularly to and horizontally from the support beam A and are movable along the support beam A. and a plurality of spacer storage boxes, which are movable along the support beam B and have spacer extrusion means attached to the lower part thereof, are suspended from the support beam B. This is a spacer mounting device.

Hereinafter, embodiments of the present invention will be described based on the drawings. 3, 4, 5, 6, and 7 show embodiments of the present invention, in which the spacer mounting device 1 includes a cart portion 2,
It consists of a lift mechanism section 3 and a spacer storage section 4.

A traveling motor 6 is disposed on the truck 5 of the truck section 2, and the power from the traveling motor 6 is transmitted to the wheels 7 through a sprocket wheel (not shown) and a chain (not shown). It's summery. Limit switches 8a and 8b are provided at the front and rear ends of the truck 5 to ensure safe forward and backward movement of the spacer mounting device 1. The arm 9 of the lift mechanism section 3 is attached to the trolley 5.
An arm drive motor 10 is provided to move the arm up and down. A column 11 of the lift mechanism section 3 is erected on the truck 5.

The tower column 11 of the lift mechanism section 3 is provided with an arm 9 whose front end projects horizontally from the tower column 11 and whose rear end slides along the tower column 11 and is vertically movable. A support beam 12 is provided at the tip of the arm 9, perpendicular to the arm 9 and horizontally. A pulley 13 is disposed at the head of the column 11, and a rope 14 provided between the arm 9 and the arm drive motor 10 is hung on the pulley 13, and is driven by the winch action of the arm drive motor 10. This allows the arm 9 to move up and down. Limit switches 15a and 15b are provided at the head and legs of the column 11 to limit the vertical movement of the arm 9.

The five support beams 16 of the spacer storage section 4 are connected to the support beams 12 of the lift mechanism section 3 via rollers 17.
Each of them is suspended horizontally and perpendicular to the support beam 12, and each of them is movable along the support beam 12 and can be fixed to the support beam 12 via a stopper 18. A spacer storage box 19 is suspended from both ends of each of the five support beams 16 via rollers 20, and the spacer storage box 19 is connected to the support beam 16.
It is now possible to move freely along the However, its range of movement is limited by a stopper pin 21 provided on the support beam 16. The spacer storage box 19 is provided with a touch sensor 25 that operates a limit switch 24 when the rod 23 comes into contact with the slab 22. An opening is provided on one side of the lower part of the spacer storage box 19, and an air cylinder 26 is provided on the opposite side. The spacer is pushed out from the opening by the operation of the air cylinder 26.

Incidentally, as the spacer Mumbo stored in the spacer storage box 19, a steel material such as a bloom beam blank or a heat-resistant brick is used.

Next, a method of using the spacer mounting device shown in the embodiment will be explained. The usage procedure is performed in the following order.

When the slabs 22 stacked in the rental car 27 are transported to an area near the blooming soaking furnace (at this time, the spacer mounting device 1 is evacuated),
Arm drive motor 10 of spacer mounting device 1
is driven to lower the arm 9 and hold it at an arbitrary position.

The support beam 16 is moved in accordance with the length of the slab 22 (in the direction perpendicular to the plane of the paper in FIG. 3), the support beam 16 is fixed to the support beam 12 via the stopper 18, and the support beam 16 is moved in accordance with the width of the slab 22. The spacer storage box 19 is moved along the support beam 16 to adjust the position of the spacer storage box 19.

The spacer is stored in the spacer storage box 19.

The arm drive motor 10 is driven to raise the arm 9.

The truck 5 is run and placed adjacent to a rented vehicle 27 in which slabs 22 are stacked.

The arm 9 is lowered, and when the touch sensor 25 of the spacer storage box 19 comes into contact with the slab 22, the lowering is stopped.

The air cylinder 26 is operated to push out the spacer from the opening of the spacer storage box 19 and place the spacer on the slab 22.

Raise arm 9.

The trolley 5 is evacuated.

The slab 22 is placed into a bloom soaking furnace using a crane (not shown).

The above procedure is repeated to place a spacer on each flag 22.

Note that the above procedure is automatically performed by remote control.

The present invention has the above-mentioned structure, and since the position of the spacer storage box is easy to adjust, it is possible to arrange the spacers according to the length and width of the slab, and the work of placing the spacers can be done in a short time. As a result, work efficiency is improved, and furthermore, the spacer placement work is accurate and malfunction does not occur.
