Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a furnace building tower equipment, and more particularly, to a furnace building tower equipment for building bricks in a furnace body such as a converter or an electric furnace.

[0002]

2. Description of the Related Art Heat-resistant bricks are built on the inner wall of a furnace body such as a converter or an electric furnace in order to protect the furnace body from the heat of molten metal. Although this brick has heat resistance, the temperature inside the furnace becomes extremely high, so the melting of the brick due to use of the furnace is severe, and it is usually replaced with a new brick once every 1 to 6 months. ing. This brick replacement is done by breaking down and removing old bricks and building new bricks on the inner wall of the furnace.

One of the furnace construction works for building this brick in the furnace body
As one method, conventionally, for example, as disclosed in FIG. 7 of Japanese Examined Patent Publication No. 4-18003 / 1989, a method is known in which an opening portion that is openably and closably provided in a furnace bottom portion of a furnace body is used. . This is composed of a moving carriage arranged below the furnace body having an opening at the bottom of the furnace and a number of frame units that are sequentially stacked on the moving carriage and inserted into the furnace through the opening. The frame unit is provided with a brick lifting device which is a combination of a fixed ladder called a fixed beam and a lifting ladder called a lifting beam, which are vertically installed at a predetermined interval from each other. By continuously moving up and down, bricks are lifted by sequentially jumping up and down the elevator ladder, fixed ladder, and elevator ladder. This eliminates the need for the operator to lift the brick loading device into the furnace mouth to the furnace mouth at the top of the furnace or to carry a large number of bricks to the furnace mouth during the furnace construction work. It is possible to reduce the number of workers and improve workability.

However, since the lifting device is of an assembling type as described above, an operator must stack the frame units in the furnace body in accordance with the progress of the brick building work. Although it is not as easy as bringing it in, there was a problem that the assembly work of the device for bringing this brick into the furnace was troublesome. Further, since the frame unit is a frame-type unit having no wall, there is a problem in safety because the load tends to collapse during lifting of bricks.

Therefore, as a means for solving this, the "furnace construction facility" of Japanese Patent Application Laid-Open No. 6-109374 filed by the applicant of the present application is known. In this product, a tower that can be easily expanded and contracted is installed on the moving carriage, the moving carriage is placed at the bottom of the furnace body, and then the tower is extended by the expansion and contraction mechanism to open the furnace from the opening at the bottom of the furnace body. After inserting the work stage and the operator's boarding stage suspended from the furnace opening on the upper part of the furnace body into the upper part of the tower selectively according to the height position of the furnace construction work, The elevating device at the top of the tower lifts the elevating platform on which the bricks are piled up along the cavity inside the tower where the bricks will not fall to the outside. Brick is laid on the inner wall of the body.

[0006]

However, in the above-mentioned conventional equipment, the work stage and the loading stage are selectively arranged above the furnace body depending on the height position of the furnace construction work. Since it was hung from the mouth and assembled to the upper part of the tower, it was improved compared to the conventional equipment, but it took time to assemble, replace, and remove these stages, and the whole furnace construction work was done. However, there is a problem that the working time of the item tends to be a little longer. Further, as described above, since the lifting device for the lifting platform, which is heavy in weight, is provided at the upper part of the tower, it is necessary to employ a tower having a large strength and a telescopic mechanism having a large output, which increases the equipment cost. There was a problem.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a furnace building tower equipment capable of improving the workability of the furnace building work and reducing the equipment cost.

[0008]

A method according to the above-mentioned object.
The furnace construction tower equipment described is a moving carriage disposed below a furnace body having an opening at the bottom of the furnace, and a movable carriage provided on the moving carriage and extendably inserted into the furnace body through the opening. A tower, an expansion and contraction mechanism of the tower, an elevating table for elevating and lowering a cavity in the tower to bring bricks for furnace construction into the furnace body, and provided around the lower side of the tower, An elevating device that elevates and lowers the elevating table, a work deck that is provided in the upper part of the tower, can be taken in and out of the furnace through an opening in the bottom of the furnace, and is provided in the upper part of the tower,
And a payout means for horizontally discharging the bricks from the elevating table. It should be noted that the vicinity of the lower side of the tower where the lifting device is provided here includes not only the lower side of the literal tower but also the vicinity of the tower installation portion of the mobile carriage.

According to a second aspect of the present invention, in the furnace construction tower facility according to the first aspect, there is provided a winch in which an elevating device for the elevating table is mounted near a tower installation portion of the movable carriage. And a fixed pulley disposed on the upper portion of the work deck. Further, the furnace building tower equipment according to claim 3 is the furnace building tower equipment according to claim 1 or 2, wherein:
It is configured to provide an assembly deck arranged on the outer peripheral side of the work deck.

[0010]

In the furnace construction tower equipment according to claims 1 to 3, a movable carriage is arranged below the furnace body, and the tower on the movable carriage is extended by a predetermined length by an expansion / contraction mechanism, and this is installed at the bottom of the furnace. The work deck can be moved to a predetermined furnace construction work position in the furnace body simply by inserting it from the opening into the furnace body, which improves the workability of the furnace construction work. In addition, a heavy lifting device is installed around the lower side of the tower, and this lifting device moves the lifting platform up and down in the cavity of the tower, and the bricks for building the furnace are sequentially loaded into the furnace body. Therefore, it is not necessary to move the heavy lifting device up and down together, and thus a tower having a relatively low rigidity and a telescopic mechanism having a relatively low output can be adopted.

Particularly, in the furnace construction tower equipment according to the second aspect, since the wire rope is pulled out or wound up from the winch attached to the vicinity of the tower installation portion of the moving carriage, the elevating platform is raised and lowered. The parts of the lifting device to be used are only lightweight wire ropes and pulleys, and the burden on the lifting mechanism is further reduced.

Further, in the blast tower equipment according to the third aspect of the present invention, for example, at the time of blasting work of the furnace top or furnace bottom having a relatively small furnace inner diameter, the work is performed on the work deck, while the furnace inner diameter is relatively small. When performing a furnace construction work in a large body part, since an assembly deck is arranged on the outer peripheral side of the work deck and the work is performed on it, the furnace construction work can be performed over the entire furnace body.

Next, the operation of the furnace building tower equipment 10 according to one embodiment of the present invention will be described. As shown in FIGS. 1, 2, and 4, the tow vehicle 18 is used to move the moving carriage 15 to the rail 1.
4, the tower 16 is arranged immediately below the opening 12 of the furnace bottom 11, the lower tower part 32 is raised by the telescopic cylinder 38 to open the entrance / exit 36, and the telescopic cylinder 38 is used to move each stage rod. 39 to 41 are selectively projected from the lower tier one by one, and each tier tower section 32 to
By raising 34, the tower 16 is extended, and the working deck 17 is raised to a predetermined furnace working position in the furnace body 13. Next, the forklift truck (not shown) places the pallet 26 on which the bricks 25 are stacked directly on the lift table 46 from the entrance 36 at the bottom of the tower 16.

When the tower 16 is extended, the lifting platform 46 is also raised. The embodiment is characterized by the raising operation of the elevating table 46. That is, as shown in FIG.
First, the wire rope 57 is pulled up with the pulley 50 as a fulcrum by the extension of the tower 16, and the lift table 46 is moved to the first position.
The limit switch 125 of. Based on this detection signal, the extension of the telescopic cylinder 38 is stopped, the drive motor 106 of the lifting device 66 is driven, and the wire rope 57 is led out from each drum 100 for, for example, 6 seconds, and the lifting platform 46 is moved to a predetermined length. Only lower it. Then, similarly, the tower 16 is again extended to pull up the elevating table 46, and when it abuts on the first limit switch 125, the extension of the tower 16 is stopped again and the drum 1 is held for 6 seconds.
The wire rope 57 is derived from 00. Hereinafter, this operation is repeated until the work deck 17 reaches a predetermined height.

After that, the telescopic arm 52 is projected from the inside of the working deck 17 manually or by a hydraulic cylinder (not shown), and the scaffold plate 55 is laid on the telescopic arm 52 to expand the scaffolding of the working deck 17. Further, in parallel with the work of expanding the scaffold, when the work deck 17 reaches a preset height, the wire rope 57 is led out from the drum 100, and the lift table 46 is brought into contact with the fourth limit switch 128. After that, the brick 25 is mounted on the lifting table 46 by a forklift truck (not shown) that is waiting below, and then the wire rope 57 is set on the drum 100 and the lifting table 46 is set on the first limit switch 125. It is wound up until it abuts, and based on the detection signal, the lift table stopper 12
4 is projected and the lifting table 46 is slightly lowered, so that the lifting table 46 is placed on the lifting table stopper 124, and the drum 10 is moved by the second limit switch 126.
The derivation of the wire rope 57 from 0 is stopped.

On the other hand, on the work deck 17, the pallets 26 loaded with the bricks 25 are discharged in a predetermined direction by the roller conveyors 51 and 67, and the worker performs a manual work or a furnace construction work using a predetermined brick stacking device. These operations are repeated until the work at the furnace construction work position is completed.

After that, the telescopic arm 52 and the lift base stopper 124 are removed, the tower 16 is extended while the wire rope 57 is being pulled out from the drum 100 and the winding operation is performed, and the working deck 17 is subjected to the next furnace construction work. The work deck 17 is raised to the position, the work deck 17 is supported by the telescopic arm 52 and the lift base 46 is supported by the lift base stopper 124 at that height position, and then the same furnace construction work is performed.

When the work for constructing the entire furnace body 13 is completed,
The tower 16 is contracted by the telescopic cylinder 38,
The working deck 17 is pulled out of the furnace through the opening 12 of the furnace body 13. At this time, contrary to the case where the tower 16 is raised, when the lift table 46 comes into contact with the third limit switch 127 due to the contraction of the tower 16, the contraction of the tower 16 is stopped and the wire rope 57 is attached to the drum 100, for example, 6 mm. Take up only for a second, and then shrink the tower 16 and lift the platform 4
When 6 comes into contact with the third limit switch 127, the operation of stopping the contraction of the tower 16 and winding the wire rope 57 for 6 seconds is repeated until the tower 16 is completely contracted. Finally, the wire rope 57 of the drum 100 is led out until the lifting table 46 comes into contact with the fourth limit switch 128, and the work is completed.

As described above, the tower 16 is lifted by the telescopic cylinder 38 and the lift table 46 is lifted by the lift device 66.
When the tower is expanded or contracted, for example, the expansion / contraction operation of the rods 39 to 41 of the telescopic cylinder 38 and the elevating / lowering of the elevating table 46 accompanied by the wire rope 57 being pulled out and wound by the elevating device 66 are performed. Compared with the case where the operation and the operation are performed at the same time, the lifting and lowering can be controlled more easily and the operation becomes reliable. However, it goes without saying that the lifting operation is not limited to this. Further, by simply extending the tower 16 by a predetermined length by the telescopic cylinder 38 and inserting it into the furnace body 13 through the opening 12 of the furnace bottom 11,
Since the work deck 17 can be moved to a predetermined furnace construction work position in the furnace body 13, workability of the furnace construction work is improved.

Further, since the lifting device 66 of the heavy lifting table 46 is provided on both sides of the tower 16 of the moving carriage 15, when the tower 16 is moved up and down, a heavy lifting device as in the conventional case is also lifted. Therefore, the tower 16 having a relatively small rigidity and the telescopic cylinder 38 having a relatively small output can be employed. Furthermore, since the wire rope 57 is pulled out or wound up from the lifting device 66, which is a winch attached near the tower installation part of the movable carriage 15, the lifting platform 46 is lifted and lowered, and thus the lifting device 66 that is lifted and lowered by the tower 16. Since only the lightweight wire rope 57 and the pulley 71 are provided, the load on the telescopic cylinder 38 is further reduced.

Further, for example, when the furnace top 121 or the furnace bottom 11 having a relatively small furnace inner diameter is constructed, the work deck 17 is used.
Work on the other hand, while the body 120 with a relatively large furnace inner diameter
When carrying out the internal furnace construction work, since the scaffold plate 55 is arranged on the outer peripheral side of the work deck 17 and the work is carried out on the scaffold plate 55, the entire furnace body 13 can be constructed. Since the scaffolding plate 55 is assembled on the basis of the two-stage rod type telescopic arm 52 radially accommodated in the working deck 17, even if the furnace body 13 is relatively large, The scaffolding plate 55 can be assembled according to the inner diameter of the scaffold.

The present invention is not limited to the above-mentioned embodiment. For example, in the embodiment, a converter is illustrated as the furnace body constructed by the furnace construction equipment of the present invention. The type of furnace is not limited as long as it is a furnace body in which bricks are built. Further, in the embodiment, the telescopic cylinder is adopted as the expansion and contraction mechanism of the tower, but the invention is not limited as long as the tower can be expanded and contracted like a general cylinder.

Further, in the embodiment, the elevating device is provided near the tower installation part of the moving carriage, but not limited to this, for example, it may be provided at an arbitrary position below the center in the height direction of the tower. May be. Furthermore, in the embodiment, the winch is shown as the lifting device, but the lifting device is not limited to this and may be another lifting device of cylinder type, for example.

In the embodiment, the assembly deck is provided on the outer peripheral side of the work deck, but without being limited to this, it is possible to secure other scaffolding even if the furnace body is small or large. If you don't have an assembly deck, you don't have to.

[0036]

According to the furnace construction facility of the first to third aspects of the invention, the tower on the moving carriage is extended by a predetermined length by the telescopic mechanism, and this is extended from the opening at the bottom of the furnace to the inside of the furnace. The work deck can be moved to a predetermined furnace-building work position in the furnace body simply by inserting it into the furnace. Therefore, the workability of the furnace-building work can be improved. In addition, since a heavy lifting device is installed around the lower side of the tower, it is not necessary to move the heavy lifting device together when the tower is lifted or lowered. A small expansion mechanism can be adopted, and the cost can be reduced.

Particularly, in the furnace construction tower equipment according to the second aspect, since the wire rope is led out or wound up from the winch attached near the tower installation portion of the moving carriage, the elevating platform is raised and lowered. Since only the lightweight wire ropes and pulleys are used as the lifting device that is lifted and lowered by the tower, the burden on the lifting mechanism can be further reduced.

Further, in the furnace building tower equipment according to the third aspect, since the working deck is provided with the assembly deck for expanding the scaffolding, the working deck is used during the work for building the furnace top or the furnace bottom having a small furnace inner diameter. When performing the above-mentioned work, and at the time of the furnace-building work in the body part having a relatively large furnace inner diameter, the assembly deck can be assembled and the work can be performed on it, whereby the furnace-building work can be performed over the entire furnace body.
