BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure of a tower elevating mechanism of a tower facility, and more particularly, to a multi-stage tube-type cylinder in which a plurality of stages of tubular members are connected in a stretchable manner. The present invention relates to a mounting structure of a tower elevating mechanism of tower equipment which can be moved up and down freely.

2. Description of the Related Art Heat-resistant bricks are laid on the inner wall of a furnace such as a converter or an electric furnace in order to protect the furnace from the heat of molten metal. Although this brick has heat resistance, the temperature inside the furnace becomes extremely high, so the brick is severely eroded by the use of the furnace, and it is usually replaced with a new brick about once a month. . The replacement of this brick
This is done by breaking down old bricks, removing them, and laying new bricks on the inner wall of the furnace (furnace).

[0003] One of the furnace-building work for laying this brick in the furnace body
As one of the methods, a method using a furnace opening portion opened in the furnace upper part is known. In this work, prior to the work, a lowering device that brings bricks into the furnace from the furnace mouth is brought into the furnace body, and then the worker transports the bricks to the furnace mouth, and then the bricks that are carried are lowered. , It is sequentially lowered into the furnace body and carried out horizontally at a predetermined height position,
Thereafter, this is manually laid by an operator on the inner wall of the furnace body.

[0004] By the way, various auxiliary facilities required for melting metal, for example, are provided above the furnace opening, and it is extremely difficult to bring a large descending device into the furnace from the furnace opening. It is. Therefore, the lowering device is taken into the furnace body from the furnace mouth in a disassembled state, and means for assembling in the furnace body is employed.However, an operator transports the disassembled lowering device to the furnace mouth portion and raises the furnace. It took considerable effort to bring it into the body. Also, during the furnace construction work, the workers must carry the bricks to the furnace opening,
This work also required a great deal of labor.

[0005] Therefore, as a countermeasure, an opening that can be opened and closed is provided in the furnace bottom of the furnace body, and a lifting device for lifting bricks is inserted into the furnace body from the opening, and the bricks are removed from below the furnace body by the lifting device. There is known one that is carried into a furnace. Conventionally, as a method for carrying bricks into the furnace through such an opening at the bottom of the furnace, for example, the structure disclosed in FIG. 7 of Japanese Patent Publication No. 4-18003 is known.

[0006] This is a movable truck disposed below a furnace body having an opening at the bottom of the furnace, and a plurality of trucks sequentially stacked on the movable truck and inserted into the furnace through the opening. A frame unit is provided, and a fixed ladder called a fixed beam vertically suspended at a predetermined interval from each other inside the frame unit, and a brick lifting device combining a lifting ladder called an elevating beam are arranged, By continuously moving up and down the lift ladder, bricks are sequentially jumped up and down as a lift ladder, a fixed ladder, a lift ladder, and so on. This eliminates the need for the operator to lift the device for bringing bricks into the furnace to the furnace opening at the top of the furnace, or to carry many bricks to the furnace opening during furnace construction. Therefore, the number of workers can be reduced and workability can be improved.

[0007]

However, in the above-mentioned conventional furnace construction equipment, since the lifting device is assembled as described above, an operator moves the frame unit in the furnace as the brick laying operation progresses. However, there is a problem that the operation of assembling a device for bringing the bricks into the furnace is troublesome, although it is not as much as the case where the bricks are brought in from the furnace opening at the upper part of the furnace. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a mounting structure of a tower elevating mechanism of a tower facility capable of improving workability of a telescopic work of a tower having a lifting mechanism.

[0008]

According to the present invention, there is provided a semiconductor device comprising:
The installation structure of the tower elevating mechanism of the described tower equipment is
The transfer port of the transferred object is opened to the lower side, and a multi-stage tubular tower in which a plurality of tubular members are provided so as to be extendable and retractable in a tubular base portion mounted on a movable trolley, A plurality of multi-stage tube-type cylinders having a multi-stage tube-shaped rod equally arranged around the tower and connected to the cylindrical member; and A lifting platform that lifts the transported object loaded into the tower from the transport port to the top of the tower, and a lower end of the multi-stage tube-type cylinder is attached to the movable carriage to which the base is attached. It is mounted so as to be tiltable in a free direction via a spherical bearing.

[0009]

In the mounting structure of the tower elevating mechanism of the tower equipment according to the present invention, when the multi-stage tube type cylinder is driven, the rod of each stage is taken out and the cylindrical member of each stage is raised and lowered. For example, when a force is applied to the multi-stage tube type cylinder from the lateral direction for some reason such as when the tower expands and contracts, the multi-stage tube type cylinder tilts laterally around the spherical bearing. For this reason, no bending moment is applied to each multi-stage tube type cylinder, which can prevent buckling of the multi-stage tube type cylinder and uneven wear of the cylinder mounting portion.

When the tower is extended to a predetermined height, the object to be conveyed is carried into the elevating table in the tower from the conveying port, and then the elevating table is raised by the elevating device to move the object to the upper part of the tower. Lift up. As described above, the multi-stage tubular tower in which a plurality of stages of tubular members are telescopically connected to each other is lifted and lowered by the multi-stage tube type cylinder. Improvement can be achieved.

In order to prevent contact with the left and right inner walls of the lower end of the tower 34, cutouts 103 are formed in the left and right inner walls near the corners of the lower ends of the towers 32 to 34, respectively, as shown in FIG. A guide roller 104 is provided in the section 103.

In FIG. 1, reference numeral 105 denotes a receiving tube for the brick 25, reference numeral 106 denotes a cable bearer, reference numeral 107 denotes an upper part of the furnace,
Reference numeral 8 denotes a furnace opening opened in the furnace upper part 107; 109, a furnace central part; 110, a crane; and 111, a forklift truck.

Next, the operation of the furnace building equipment 10 to which the mounting structure of the tower elevating mechanism of the tower equipment according to one embodiment of the present invention is applied will be described. The work stage 17 and the boarding stage 18 are separated from the tower 16 in advance and stored on both sides of the tower 16 of the movable trolley 15 as shown by a chain line in FIG. At this time, the dispensing device 49 is manually or electrically driven and the outrigger 5 is operated so that the work stage 17 does not obstruct the passage of the opening 12.
2 is rotated upward by the cylinder 45a. During the furnace-building operation of the furnace bottom 11 of the furnace body 13, first, the receiving tube 105 of the brick 25 is mounted in the opening 12, and the moving stage 18 is moved so that the boarding stage 18 is located immediately below the opening 12 of the furnace bottom 11. The carriage 15 is moved below the furnace body 13, the boarding stage 18 is lifted by the crane 110 from above the furnace port 108 of the furnace upper part 107, and the movable carriage 15 is moved to move the tower 1.
6 is positioned immediately below the opening 12 of the furnace bottom 11, the suspended stage 18 is lowered, and the stage 18 is assembled to the upper portion of the tower 16 with bolts.

Next, as shown in FIGS. 5 and 9, when both telescopic cylinders 38 are simultaneously driven, the respective lower rods 39 protrude, and the lower tower portion 32 of the tower 16 rises together with the other tower portions 33 and 34. The boarding stage 18 passes through the opening 12 and rises into the furnace bottom 11. At this time, since the steel ball 42f is interposed between the upper connection seat 42b and the lower connection seat 42c of the connection portion 42B that connects the lower tower portion 32 and the lower rod 39, the tower 16 that is moving up and down swings. Even if the tower 16 is subjected to a slight tilting force, the steel ball 4
The upper connection seat 42b rotates about 2f, and the lower rod 3
9 has no bending moment, so that the lower rod 39 always has a strong force.
The lower rods 39 are projected with the same height. For this reason, it is possible to prevent the tower 16 from being obstructed from rising due to the tower 16 rising in the inclined state. Since the upper connection seat 42b and the lower connection seat 42c are connected by the connection plate 42g, the upper connection seat 42b does not seem to rotate at first glance, but as shown in FIG. 16, the lower connection seat 42c and the connection plate 42g Since the bolts 42h that connect the upper connection seat 42b are only loosely inserted into the holes 42i formed in the lower connection seat 42c, they do not hinder the rotation of the upper connection seat 42b.

Further, when the tower 16 is extended or the work stage 17 is moved by the outrigger 52 described later,
3 when the telescopic cylinder 38 is fixed.
When a force is applied from the side in the lateral direction, the telescopic cylinder 38 rotates laterally around the spherical bearing as shown by the chain line in FIG. 4 to eliminate the inconvenience when the telescopic cylinder 38 is fixed. . That is, the telescopic cylinder 38
When a force is applied from the side in the lateral direction, the upper seat 38b provided at the lower end of the telescopic cylinder 38 draws a curve along the saucer-shaped upper surface of the lower seat 38f provided at the attachment 38d of the movable carriage 15. As a result, the telescopic cylinder 38 rotates in the direction of the force. For this reason, no bending moment is applied to the telescopic cylinder 38, and therefore, the buckling of the telescopic cylinder 38 and the telescopic cylinder 38
Uneven wear of the mounting portion 38d can be prevented.

Further, when the tower 16 is extended, as shown in FIG.
The entrances 36 and 37 provided in the lower part of 6 open. As described above, the lower tower portion 32 rises without driving the middle tower portion 33 and the upper tower portion 34 by driving the telescopic cylinder 38 because the cross-sectional area is large when the load applied to the rods 39 to 41 is large. This is because the characteristic of the telescopic cylinder 38 that expands and contracts sequentially from the rod is used. That is, as shown in FIG. 5, a heavy-weight boarding stage 18 is mounted on the tower 16, and the tower sections 32-34 are connected to the rods 39-41, respectively, so that the telescopic cylinder 38 is driven. First, the lower rod 39 having the largest cross-sectional area first protrudes while pushing up the other rods 40 and 41, and the lower tower portion 32 connected to the lower rod 39 with this projection.
Rises together with the other tower portions 33 and 34.

As described above, the entrances 36 and 37 opened in the base 31 are always opened when the lower tower 32 raised first by the telescopic cylinder 38 rises. Irrespective of the part of the furnace body 13 such as the part 109 and the furnace upper part 107, when the tower 16 is extended and the furnace construction work is performed, the entrances and exits 36 and 37 are always opened, and the pallet 26 is opened from these entrances and exits 37 and 37. Can be put in and out.

Next, a pallet 26 on which the bricks 25 are placed
3 is carried into the carry-in conveyor 28 by the forklift truck 111, and is conveyed from the entrance 36 onto the roller conveyor 90 of the elevator 46 waiting at the lower part of the tower 16 as shown in FIG. Next, by the rotation of the motor 67 of the lifting device 66, the wire 74 is wound around the drum 71 and
6 rises up the hollow portion 35 in the tower 16 and rises to the elevator 65 of the work deck 63 as shown in FIG. At this time, even if the elevator 46 swings when the elevator 46 passes from the base unit 31 to the lower tower unit 32, FIGS.
The guide plate 102 protruding from the elevating table 46 shown in FIG.
The guide roller 104 provided at the lower end of the lower tower section 32 shown in FIG. 5 prevents the lifting table 46 from contacting the inner wall of the lower tower section 32, thereby preventing the lifting tower 46 from being raised and lowered. As shown in FIG. 12, when the elevator 46 rises to the elevator port 65, the stopper 83 is driven to project the rod 84, and the elevator 46 is supported from below.

Next, as shown in FIG. 17, a worker on the work deck 63 manually picks up the bricks 25 on the pallet 26 by manually operating the balancer 63c, and sequentially lays the bricks 25 on the inner wall of the furnace bottom 11. At this time, since the receiving cylinder 105 is attached to the opening 12 of the furnace bottom 11, it is possible to prevent the bricks 25 from sliding down the inner wall of the furnace bottom 11 inclined downward and dropping from the opening 12. The receiving cylinder 105 attached to the opening 12 is removed as needed after the bricks 25 are laid on the furnace bottom 11. At the time of furnace construction work of the furnace central part 109, first, the boarding stage 18 is temporarily removed from the tower 16 and the crane 110 is used to remove the boarding stage 18 from the tower 16 so that
8 and lifted above the furnace body 13, which is temporarily placed on the upper side of the furnace body 13. Next, the movable carriage 15 is moved to move the work stage 1 immediately below the opening 12 of the furnace bottom 11.
The work stage 17 is lifted by the crane 110 and lifted from the opening 12 into the furnace body 13.

Next, as shown in FIG.
Is moved to position the tower 16 immediately below the opening 12 in the furnace bottom 11, and the suspended work stage 17 is lowered to assemble it on the upper portion of the tower 16. Subsequently, the temporarily placed boarding stage 18 is lowered into the furnace body 13 by the crane 110, and is assembled on the work stage 17. Thereafter, as shown in FIGS. 7 and 8, the dispensing device 49 and the outrigger 52 are rotated downward, and then the cylinder 5
4a, the rod 54b is projected so that each outrigger 52
The leg 54 is extended and pressed against the inner wall of the furnace body 13 to support the work stage 17 in the furnace body 13. Further, the rod 50b of the cylinder 50a of the dispensing device 49 is protruded to push out the slide deck 50c, and then the scaffold plate 55 is assembled between each dispensing device 49 and the outrigger 52.

Next, as shown in FIGS. 1 and 9, the middle rod 40 and the upper rod 4 are moved by the telescopic cylinder 38.
The work stage 17 is raised to a predetermined position in the furnace central part 109 by raising the middle tower part 33 and the upper tower part 34 by protruding 1. At this time, similarly to the case where the lower rod 39 is raised, even if the tower 16 that is being raised is laterally swayed, as shown in FIG. 16, the upper and lower connecting seats 42b and 42c of the connecting portion 42B of the middle rod 40 as shown in FIG. By the steel ball 42f interposed therebetween, the upper connection seat 42b rotates about the steel ball 42f, and the same effect is obtained. When the tower 16 contracts when the tower 16 contracts, the tower 16 can be prevented from descending by acting in the same manner except that the rods 39 to 41 are sequentially retracted. Also, even if some resistance that hinders the contraction of the tower 16 occurs when the tower 16 contracts, the upper connection seat 42b on the tower 16 side and the lower connection seat 42c on the telescopic cylinder 38 side are connected by the connection plate 42g. Therefore, the tower 16 can be forcibly contracted when each of the rods 39 to 41 is retracted.

Thereafter, the motor 67 of the lifting device 66 is rotated to raise the lifting table 46 to the lifting port 47 of the lower plate 43 of the work stage 17, and then the motor 8 of the lifting table 46 is rotated.

Is adjusted to the carrying direction of the selected dispensing device 49. Then, the pallet 2 is moved by the roller conveyor 90.
6 is carried out from the elevating platform 46 to the selected payout device 49 in the horizontal direction. Because of this, turntable 8
With the small power of rotating the brick 8, the unloading direction of the brick 25 can be directed not only in one direction but also in many directions by the number of the dispensing devices 49. When the lift 46 is lifted, the lift 46 is attached to the base 31, the lower tower 32,
When passing between the middle tower section 33 and the upper tower section 34, the lower end of the guide plate 102 on the elevator 46 and the lower ends of the tower sections 32 to 34, as in the case of the furnace construction work of the furnace bottom section 11. The lifting table 4 is moved by a guide roller 104 provided in the section.
6 can be prevented from coming into contact with the inner walls of each of the tower portions 32-34 during ascent.

Next, as shown in FIG.
The bricks 25 on the pallet 26 are clamped and picked up by the drive of 7, and the bricks 25 are sequentially stacked on the inner wall of the furnace central portion 109 from a lower position. At this time, when the bricks 25 on the pallet 26 run out, the pallet 26 is returned to the elevator 46 and lowered in the hollow portion 35. When the bricks 25 reach the lower part of the tower 16, as shown in FIG. The pallet 26 is unloaded from the outlet 37 of the tower 16 onto the first unloading conveyor 29 by the roller conveyor 90, and is then discharged to the outside via the recovery lifter 27 and the second unloading conveyor 30 as shown in FIG. A new pallet 26 on which the bricks 25 are placed is transferred to the entrance 3 by the carry-in conveyor 28.
From 6, it is placed on the lifting platform 46, and then the lifting platform 46 is raised and lifted up to the lower plate 43. Then, the turntable 88 is rotated so that the unloading direction of the pallet 26 is adjusted to the transport direction of the next selected discharging device 49, and the pallet 26 is unloaded in the horizontal direction toward the discharging device 49, and similarly constructed. The work of laying the bricks 25 by the furnace equipment 57 is performed. These operations are repeatedly performed until the brick 25 is laid on the entire inner wall of the furnace central portion 109.

When the work stage 17 is to be fixed again above the furnace body 13 in accordance with the progress of the stacking of the bricks 25, the leg portion 54 of the outrigger 52 is once retracted by the cylinder 54a, and then the telescopic cylinder 38
The work stage 17 is raised to a predetermined position by causing the middle rod 40 and the upper rod 41 to protrude, and then the legs 54 of the outrigger 52 are protruded again.
3 is pressed against the inner wall. During the furnace construction work of the furnace upper part 107,
The upper rod 41 is further protruded by the telescopic cylinder 38, and the upper tower 34 is raised until the boarding stage 18 reaches the furnace upper part 107. Next, the lifting device 6
6, the elevator 46 is raised to the elevator 65 of the work deck 63, and then the operator manually operates the balancer 63c in the same manner as in the above-described furnace-building operation of the furnace bottom 11. Then, the bricks 25 on the pallet 26 are sequentially laid on the inner wall of the furnace upper part 107.

As described above, the tower 16 is extended by the telescopic cylinder 38, and the brick 25 is
Is carried out while carrying the furnace into the furnace body 13, so that the portion of the furnace building equipment 10 inserted into the furnace body 13 and the bricks 25 can be easily brought into the furnace body 13 and the furnace building work can be performed. Workability can be improved. In addition, the loading of the bricks 25 into the furnace body 13 is performed by the lifting platform 46 that moves up and down in the hollow portion 35 of the tower 16, so that even if the bricks 25 collapse while the bricks 25 are being lifted, the bricks 25 remain in the tower 16. It does not fall out of the tower 16 merely by falling inside, thereby preventing accidents such as damage to peripheral devices and injuries to workers. Furnace building equipment 1 inserted into furnace body 13
Because the portion of the furnace 0 is divided, the portion of the furnace construction equipment 10 inserted into the furnace body 13 can be easily replaced by a furnace even if the furnace body 13 cannot have a sufficient height from the floor surface to the furnace bottom 11. It can be inserted into the body 13. Further, since the work stage 17 and the boarding stage 18 are selectively assembled on the upper part of the tower 16, the work by the worker and the work by the furnace construction equipment 57 are selected according to the part of the furnace body 13, and the furnace construction is performed. Work can be done.

The present invention is not limited to the above-described embodiment. For example, in the embodiment, the tower equipment of the present invention is used as a furnace construction equipment. Also applicable to Further, in the embodiment, the converter is exemplified as the furnace body to be built. However, the type of the furnace is not limited as long as the furnace body has a brick laid on an inner wall such as an electric furnace. Furthermore, in the embodiment, the work stage and the boarding stage have a structure that can be separated from the tower, but the work stage and the boarding stage are fixed to the tower if the furnace body has a sufficient height from the floor surface to the furnace bottom. It may be.

[Effects of the Invention] The mounting structure of the tower elevating mechanism of the tower equipment according to the present invention has a structure in which a multi-stage cylindrical tower in which a plurality of stages of tubular members are connected in a stretchable manner is moved up and down by a multi-stage tube type cylinder. In addition, the workability of the work of expanding and contracting the tower having the lifting mechanism can be improved. In addition, since the transported object is carried into the furnace by the elevating table which moves up and down in the hollow portion of the tower, the transported object falls in the tower even if the load collapses during the lifting of the transported object. Just do not fall out of the tower,
For this reason, accidents such as damage to peripheral devices and injuries to workers can be prevented. Further, since the lower end of the multi-stage tube type cylinder is provided so as to be tiltable in a free direction around the tower via a spherical bearing, for example, when the tower expands and contracts, a force from the lateral direction is applied to the multi-stage tube type cylinder. Even if it is applied, since the multi-stage tube type cylinder is tilted in the free direction around the spherical bearing, no bending moment is applied to each multi-stage tube type cylinder, which causes buckling of the multi-stage tube type cylinder and the mounting portion of the cylinder. Uneven wear can be prevented.
