Description

  The present invention relates to a construction apparatus for constructing a kneaded material made of, for example, powder and liquid, and a construction method using the construction apparatus.

  Hereinafter, a conventional construction apparatus will be described with reference to FIGS. 9 to 12, taking as an example a case where the kneaded material is composed of an irregular refractory and water.

  FIG. 9 is a cross-sectional view of the continuous kneading and discharging machine S disclosed in Patent Documents 1 and 2. The continuous kneading and discharging machine S is composed of a conveying machine A, a kneading machine B, and a discharging machine C.

  The carrier A has a structure in which a rotating shaft 30 and a plurality of plate-like members 31 fixed thereto are accommodated in a container 34 having a supply port 32 and a water injection hole 33. The amorphous refractory supplied from the supply port 32 and the water supplied from the water injection hole 33 are conveyed to the kneader B while being mixed by the plate-like member 31.

  The kneader B has a structure in which a rotating shaft 35 and a plurality of stirring rods 36 fixed thereto are accommodated in a truncated cone-shaped container 37 that expands in the downstream direction. The amorphous refractory and water supplied from the transporter A are further kneaded by the stirring rod 36 with projection onto the inner surface of the container 37, and are transferred to the discharger C as a kneaded product.

  The discharger C has a projection disk 39 that is rotated by a rotary shaft 38. The kneaded material supplied from the kneading machine B is discharged from the discharge port 40 by the centrifugal force generated by the rotation of the projection disk 39, and is applied to the work surface. The rotary shaft 38 has a quick setting agent supply hole 41 communicating with the inside of the projection disk 39, and the quick setting agent is added to the kneaded material from the quick setting agent supply hole 41 as required.

  FIG. 10 is a plan view of the discharger C. FIG. The discharge machine C includes a projection disk 39, a plurality of blade plates 42 fixed to the projection disk 39 and extending radially from the center of the projection disk 39, and an endless flat belt 43 wound around the projection disk 39. A plurality of pulleys 44 for guiding the endless flat belt 43, a mounting plate 45 on which the pulley 44 is pivotally mounted, and a projection plate 46 fixed to the mounting plate 45 at the position of the discharge port 40 are provided.

  An endless flat belt 43 wound around the projection disk 39 is folded back by a pair of pulleys 44 located at both ends of the discharge port 40. The kneaded material supplied from the kneading machine B in FIG. 9 is distributed between the blade plates 42 and moves together with the endless flat belt 43 while being pressed against the inner surface of the endless flat belt 43 by centrifugal force. Flying from the endless flat belt 43 at the position, the discharge direction is determined by the projection plate 46, and discharged from the discharge port 40.

  FIG. 11 shows a construction apparatus provided with the continuous kneading release machine S of FIG. A base 50 is bridged over the upper opening of the ladle T that is the construction target. A ring-shaped rotating frame 51 is provided on the back side of the base 50, and a pair of vertical rails 52 extend downward from the rotating frame 51. A pair of horizontal rails 53 extending horizontally are supported by the vertical rails 52, and a frame body 54 is supported by the horizontal rails 53. A continuous kneading and discharging machine S is held on the frame body 54. The continuous kneading and discharging machine S is held so that the rotating shaft of the discharging machine C faces the horizontal direction.

  According to this construction apparatus, the continuous kneading and discharging machine S can move up and down along the vertical rail 52, can move horizontally along the horizontal rail 53, and can rotate in the horizontal plane by the rotating frame 51. Further, the discharge machine C itself can turn the discharge port 40 by 360 ° in the vertical plane. For this reason, the kneaded material can be incident on the inner surface of the ladle T from any direction.

  FIG. 12 shows another construction apparatus provided with the continuous kneading release machine S of FIG. A base 60 is bridged over the upper opening of the ladle T, and a support frame 61 is assembled on the base 60.

  Although the apparatus of FIG. 11 can discharge a kneaded material in arbitrary directions three-dimensionally, the apparatus structure is large-scale. For example, in the apparatus of FIG. 11, when the discharge port 40 is swung in a horizontal plane, all of the frame body 54, the horizontal rail 53, and the vertical rail 52 must be swung.

  The apparatus of FIG. 12 has a simple configuration in this respect. When the discharge port 40 is swung in a horizontal plane, only the discharger C needs to be swung. However, in the apparatus of FIG. 12, the discharge direction of the kneaded product cannot be adjusted in the vertical plane. For this reason, the corner R1 at the bottom of the ladle T needs to be manually constructed. In addition, when the side surface of the ladle T does not stand vertically and has an opening angle α from the vertical surface, the kneaded material cannot be vertically incident on the side surface of the ladle T. There is a drawback that things are easy to fall off.

  FIG. 13 shows a construction apparatus disclosed in Patent Document 3. In this apparatus, the blast furnace 70, not the ladle, is to be repaired, but the nozzle 71 as a discharger for discharging the kneaded material is suspended by the wire 72, and this is moved up and down by the wire 72, and the nozzle 71 is placed in a horizontal plane. It is common with the apparatus of FIG. 12 by the point provided with the turning mechanism 73 made to turn. The apparatus further includes a tilt cylinder 74 that tilts the nozzle 71 in a vertical plane.

  Therefore, it is conceivable that the tilting means similar to the tilting cylinder 74 of FIG. 13 is provided in the apparatus of FIG. 12, but if the tilting means for tilting the continuous kneading discharger S in the vertical plane is suspended by the wire 63, Since the structure of what is suspended by the wire 63 becomes large, the load applied to the wire 63 is not preferable.

  FIG. 14 shows a construction apparatus disclosed in Patent Document 4. In this apparatus, a sprayer 80 as a discharger that discharges the kneaded material is tilted in the vertical direction using the wire 81. However, since this structure is established with the support 82 that can withstand the tension of the wire 81 as an essential element, a simple structure in which the spraying machine 80 is suspended only by the wire as shown in FIG. 12 cannot be adopted. In addition, since the counterweight 83 is necessary to balance the sprayer 80, there is still room for improvement in terms of reducing the total weight of the suspended items.

  The purpose of the present invention is to adjust the discharge angle of the kneaded material in the vertical plane without increasing the total weight of the material lifted by the wire as much as possible in the construction apparatus adopting the configuration in which the discharger for discharging the kneaded material is suspended by the wire. Is to be able to do it.

According to one aspect of the present invention, wires are connected to at least three locations on the surface, and a substrate suspended by the wires and a discharge port attached to the substrate and discharging the kneaded material intersect the substrate. A discharger that can be swung around a swivel axis, and a manipulation means that is disposed above the substrate and that changes the posture of the substrate using the wire, and adjusts the inclination angle of the substrate with respect to a horizontal plane And the manipulating means having a function of rotating the substrate in a tilting direction around a virtual perpendicular intersecting the substrate without rotating the substrate around the normal line of the surface, and the tilting direction of the substrate by the manipulating unit A construction device provided with a turning mechanism for turning the discharge port of the discharger around the turning axis in synchronization with the rotation of the discharge machine. The manipulation means includes a support body that is held vertically above the substrate and to which an upper end of each wire rod is connected, and a posture change mechanism that changes the posture of the support body, or the length of each wire rod. A wire length adjuster that can adjust the length of each of the wire rods periodically changing to draw a sine curve with the same period and the same amplitude, and the number of wire rods is N, A controller that controls the wire length adjuster so that the phase of the sine curve differs by (360 / N) ° between the wires. In the latter case, the places where the N wires are connected to the substrate are located at an equal angle (360 / N) ° in plan view on the same circumference around the virtual perpendicular intersecting the substrate.

  Since the substrate posture is also adjusted using the wire rod for hanging the substrate, the discharge angle of the kneaded material is adjusted in the vertical plane without increasing or almost increasing the total weight of the material lifted by the wire rod. Can do.

  In FIG. 1, the schematic of the construction apparatus by one Example of this invention is shown.

  A base 1 is placed on the upper open end of a ladle T as a molten metal container. An opening 2 for carrying the continuous kneading and discharging machine S shown in FIG. 9 into the ladle T is formed in the central portion of the base 1 in plan view. The substrate 4 is suspended by the wire 3 passing through the opening 2, and the continuous kneading and discharging machine S is attached to the substrate 4. The winch 5 moves up and down the substrate 4 in the ladle T by winding and unwinding each wire 3.

  This construction apparatus is characterized in that it is disposed above the substrate 4 and has a manipulation mechanism 6 as a manipulation means for changing the posture of the substrate 4 using the wire 3. The manipulation mechanism 6 is supported by a frame 7 erected on the base 1 so as to straddle the opening 2.

  The manipulation mechanism 6 includes a support 8 to which the upper end of the wire 3 is connected, and a posture change mechanism 9 that changes the posture of the support 8. The support 8 is supported on the frame 7 via the universal joint 10.

  On the base 1, a hopper 11 or the like containing an irregular refractory is disposed. An irregular refractory is supplied from the hopper 11 to the supply port (the supply port 32 in FIG. 9) of the continuous kneading discharger S through the auger 12 and the rod-type telescopic tube 13 whose length can be adjusted.

  FIG. 2 is a perspective view showing the support 8, the wire 3, and the substrate 4. In FIG. 2, illustration of the winch 5, the continuous kneading discharger S, and the like in FIG. 1 is omitted.

  The support 8 includes a disk 14 and an arm body 15 that is integrated with the disk 14. The arm body 15 has a three-pointed shape having three cantilevers 15 a to 15 c extending radially from the virtual perpendicular passing through the center of the disk 14 at an equal angle (120 °) in plan view. The upper end of the wire 3 is connected to each of the cantilevers 15 a to 15 c, and the lower end of the wire 3 is connected to the surface of the substrate 4.

  In order to stably support the substrate 4, at least three wires 3 are necessary. Although FIG. 2 illustrates the case where there are three wires 3, the substrate 4 is suspended by j wires connected to j (where j is a natural number of 4 or more) on the surface of the substrate 4. May be. In this case, it goes without saying that the arm body 15 includes j cantilevers.

  FIG. 3 is a conceptual diagram for explaining the operation of the construction apparatus.

  The circular plate 14 can adjust the inclination angle θ with respect to the horizontal plane H, and the normal V at a certain reference point P on the surface is the reference point P as an apex, and the apex angle is equal to twice the inclination angle θ. The movement (hereinafter referred to as swinging movement) that moves on the side surface of the virtual cone W is held so as to be performed without rotation around the normal V. The universal joint 10 of FIG. 1 realizes such holding. The reference point P is located at the center of the surface of the disk 14.

  The posture changing mechanism 9 adjusts the inclination angle θ of the disk 14 and causes the disk 14 to perform the above-described swinging motion. The posture changing mechanism 9 includes a gripper 16 that grips the edge of the disk 14, a rotating mechanism 17 that rotates the gripper 16 along the edge of the disk 14, and a vertical displacement that displaces the gripper 16 in the vertical direction. And a mechanism 18.

  Since the gripper 16 sandwiches the edge of the disc 14 via the rollers 16 a, the gripper 16 is slidable with the disc 14 in the circumferential direction of the disc 14.

  The rotation mechanism 17 includes a base shaft 17a that extends vertically and a motor 17b that rotates the base shaft 17a. The center line of the base shaft 17a passes through the reference point P on the surface of the disk 14.

  The vertical displacement mechanism 18 is supported by the base shaft 17a in a state of intersecting with the base shaft 17a, and swings around the intersection position X with the base shaft 17a as a fulcrum, and one end of the first arm 18a. An elevator 18b that moves up and down, and a second arm 18c that has one end connected to the other end of the first arm 18a and the other end connected to the gripper 16 are configured.

  The elevator 18b is fixed to the base shaft 17a. The vertical displacement mechanism 18 and the gripper 16 rotate together with the base shaft 17a. Since the disc 14 is prohibited from rotating about the normal line V, the gripper 16 slides along the edge of the disc 14 when the motor 17b is operated.

  The tilt angle θ of the disc 14 can be adjusted by displacing the gripper 16 in the vertical direction by the vertical displacement mechanism 18. When the inclination angle θ of the disk 14 is determined to be a desired angle, the gripper 16 is turned around by the rotating mechanism 17 while maintaining the height (position in the vertical direction) of the gripper 16 at that time. 14 can be made to perform the above-mentioned rocking motion.

  Further, the gripper 16 can be moved up and down by the vertical displacement mechanism 18 while the gripper 16 is rotated by the rotation mechanism 17.

  The lengths of the wires 3 are equal to each other. In this embodiment, the winch 5 in FIG. 1 performs winding and rewinding of the three wire rods 3 under the condition that the lengths of the three wire rods 3 are equal to each other. For this reason, the board | substrate 4 always takes the attitude | position parallel to the disc 14. FIG. Therefore, the substrate 4 also performs a corresponding swinging motion with the swinging motion of the disk 14.

  Note that the lengths of the three wires 3 may be different. In this case, the substrate 4 has an inclination angle with respect to the disk 14, but if the winding amount and the unwinding amount of each wire 3 by the winch 5 are equal, the inclination angle of the substrate 4 with respect to the disk 14 is constant. To be kept. Also in this case, the swinging motion corresponding to the substrate 4 can be performed in accordance with the swinging motion of the disk 14.

  The discharger C can turn its discharge port 40 around a turning axis L that intersects the substrate 4. The motor 19 attached to the substrate 4 rotates the discharge port 40 of the discharge machine C.

  The controller 20 controls the motor 19, the motor 17b, and the elevator 18b.

  FIGS. 4A to 4E are schematic views showing changes in the posture of the substrate 4 accompanying the swinging motion of the disc 14. In FIG. 4, U indicates a virtual perpendicular line that intersects with the substrate 4 also illustrated in FIG. 3, and an arrow g indicates the inclination direction of the substrate 4. Here, the inclination direction of the substrate 4 refers to the gradient direction in the vector analysis on the surface of the substrate 4.

  As shown in FIGS. 4A to 4E, the substrate 4 moves around the virtual perpendicular line U intersecting the substrate 4 in accordance with the swinging motion of the disk 14 shown in FIG. Do. The controller 20 in FIG. 3 rotates the discharge port 40 in synchronization with the rotation in the tilt direction g of the substrate 4 so that the discharge port 40 of the discharge machine C always faces the tilt direction g of the substrate 4. The turning mechanism of the present invention is configured by the controller 20 and the motor 19 of FIG.

  According to this apparatus, since the tilt angle of the substrate 4 is adjusted by using the wire 3 that suspends the discharge machine C and the substrate 4, the total weight of the material suspended by the wire 3 is not increased or hardly increased. The discharge angle of the kneaded product can be adjusted in the vertical plane.

  Returning to FIG. 1, the repair method of the ladle T using this construction apparatus is demonstrated.

  First, the substrate 4 is lowered from the bottom of the pan T to a certain height. Next, the discharge port 40 of the discharger C is directed to the bottom corner of the pan T by adjusting the tilt angle of the substrate 4 with respect to the horizontal plane by the operating mechanism 6. The inclination angle of the substrate 4 at this time is, for example, 10 to 30 °.

  Next, while maintaining the tilt angle of the substrate 4 in this state, as described with reference to FIG. 4, the tilting direction of the substrate 4 is rotated by the operating mechanism 6, and the discharge port 40 is synchronized with the rotation. The corner R1 is constructed over the entire circumference by turning.

  Next, after the corner R1 is constructed, every time the discharge port 40 of the discharger C is rotated 360 × k ° (where k is a natural number) while maintaining the height of the substrate 4, the horizontal plane of the substrate 4 is maintained. While repeating the step of bringing the inclination angle close to zero, the region R2 is constructed up to a height at which the inclination angle of the substrate 4 becomes equal to the opening angle α of the side surface of the ladle T.

  Here, the opening angle α of the side surface of the ladle T is, for example, more than 0 ° and about 6 ° or less. When the inclination angle of the substrate 4 is equal to the opening angle α of the side surface of the ladle T, the kneaded material discharged from the discharge port 40 enters the inner surface of the ladle T perpendicularly.

  Next, while keeping the inclination angle of the substrate equal to the opening angle α of the pan, the process of winding the wire 3 with the winch 5 every time the discharge port 40 of the discharge machine C is rotated 360 × k ° is repeated, The construction of the higher region R3 on the side of the ladle T is performed.

  By keeping the inclination angle of the substrate 4 equal to the opening angle α of the side surface of the ladle T, the kneaded material discharged from the discharge port 40 is perpendicularly incident on the side surface of the ladle T. Compared with the case where it enters, the adhesion rate of the kneaded material to the inner surface of the ladle T can be increased.

  With the above, the construction of the entire side surface of the ladle T is completed. In addition, since the bottom surface of the ladle T lays a precast book, it is not necessary to apply the kneaded material.

  Conventionally, when the apparatus of FIG. 12 is used, the discharge port 40 cannot be tilted in the vertical direction. Therefore, the corner R1 and the region R2 have to be manually constructed, but according to the apparatus of FIG. Construction of the corner R1 and the region R2 can also be automatically performed.

In this embodiment, the position where the inclination angle of the substrate 4 is equal to the opening angle α of the ladle T side surface is defined as the boundary between the regions R2 and R3, but the inclination angle of the substrate 4 is the opening angle of the ladle T side surface. The region R3 may be constructed in a state where a certain angle in the range of α ± 5 ° is set as a boundary between the regions R2 and R3 and the certain angle is maintained. If the inclination angle of the substrate 4 is in the range of the opening angle α ± 5 ° on the side surface of the ladle T, the kneaded material discharged from the discharge port 40 can enter the side surface of the ladle T almost perpendicularly. The adhesion rate can be increased.

  Moreover, although the above demonstrated the case where it constructs toward the top opening from the bottom part of the ladle T, the same process can be performed in the reverse procedure and it can construct toward the bottom part from the top opening of the ladle T.

  FIG. 5 is a schematic view showing a part of a construction apparatus according to another embodiment. The illustration of the configuration common to FIG. 3 is omitted. As shown in FIG. 5, the arm body 15 of FIG. 3 may be omitted, and the substrate 4 may be directly suspended from the disk 14. However, as shown in FIG. 3, the arm body 15 is advantageous in that the diameter of the disc 4 can be made smaller, and the rotational radius of the gripper 16 can be made smaller.

  FIG. 6 is a schematic view showing a part of a construction apparatus according to still another embodiment. The illustration of the configuration common to FIG. 3 is omitted. As shown in FIG. 6, by connecting the gripper 16 directly to the elevator 18b, the first arm 18a of FIG. 3 is not required, and the posture changing mechanism 9 can be simplified.

  FIG. 7 is a schematic view showing a part of a construction apparatus according to still another embodiment. Illustration of the configuration common to the apparatus of FIG. 1 is omitted. In this embodiment, the operating mechanism 6 shown in FIG. 1 is not provided, and the operating means for changing the posture of the substrate 4 using the wire 3 is realized by the winch 5 and the winch controller 21 for controlling the winch.

  In this embodiment, it is assumed that the winch 5 is fixed to the support frame 7 of FIG. In the present embodiment, the winch 5 has a function of individually adjusting the length of each wire 3. The winch controller 21 controls the position of the substrate 4 by controlling the winch 5 so that the lengths of the respective wires 3 are different from each other. In this embodiment, the winch 5 functions as a wire length adjuster.

  FIG. 8 is a waveform showing the change over time of the length of each wire 3 in FIG. The horizontal axis indicates time, and the vertical axis indicates the length of the wire. Waveform a shows a change in the length of a certain wire 3, waveform b shows a change in the length of another wire, and waveform c shows a change in the length of the remaining wire.

  The length of each wire 3 changes periodically so as to draw a sine curve with the same period and the same amplitude 2M. By varying the phase of the sine curve indicating the change in length by 120 ° between the wires 3, the substrate 4 can be caused to perform the swing motion.

  Further, the tilt angle θ of the substrate can be adjusted according to the magnitude of the amplitude M. When N wires are used, the above-described swinging motion can be performed by making the phase between the wires 3 different by (360 / N) °.

  Such a change in the length of each wire 3 is realized by the winch controller 21 in FIG. 7 controlling the winch 5. This function of the winch controller 21 can be realized by software, for example. According to the embodiment of FIG. 7, the operation mechanism 6 is not required as compared with the embodiment of FIG.

  As mentioned above, although the specific example of this invention was demonstrated, this invention is not limited to this.

  For example, FIG. 4 shows a pattern in which the discharge port 40 is swung so that the discharge port 40 of the discharge machine C always faces the tilt direction g of the substrate 4, but the angular velocity in the tilt direction g around the virtual perpendicular U If the angular velocity of the discharge port 40 around the turning axis L in FIG. 3 is equal, there may be a phase difference between the rotations of the two. That is, in the planar projection view, the discharge port 40 of the discharger C does not necessarily have to be positioned on the extended line of the arrow indicating the inclination direction g.

  In this specification, rotating the discharge port in synchronism with the rotation of the substrate in the tilt direction means that the angular velocity of the rotation of the discharge port 40 around the rotation axis L in FIG. It is set to a value according to the angular velocity. Both angular velocities are preferably equal, and the phase difference between the two is preferably zero.

  In addition, a chain, a wire, etc. can be used for a wire, for example. Further, the discharger is not limited to the one shown in FIG. 9 as long as it discharges the kneaded material from the discharge port. The method of discharging the kneaded product is not limited to centrifugal projection, and may be spraying by pumping or airflow conveyance using compressed air. That is, the discharge port may be a nozzle. Further, the kneaded product is not limited to a kneaded amorphous refractory with water, and may be a kneaded powder such as mortar or concrete. It will be apparent to those skilled in the art that various combinations and improvements can be made.

  INDUSTRIAL APPLICABILITY The present invention can be particularly preferably used for construction of an irregular refractory material on a ladle, a hot metal ladle, a converter, a blast furnace, or other molten metal containers. The molten metal container preferably has a circular cross section. The present invention can also be widely used for concrete and mortar construction.
