Description

[Technical Field]

[0001] The present disclosure relates to a guide and holding device for cables and a continuous casting facility. [Background technology]

[0002] Patent Document 1 discloses a continuous casting facility in which a tundish car for holding a tundish is configured to be movable between a casting position and a preheating position. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 8-294756 Summary of the Invention [Problem to be solved by the invention]

[0004] Although not disclosed in Patent Document 1, cables necessary for continuous casting operations (for example, electrical wiring, piping for hydraulic oil for a hydraulic drive system, piping for supplying gas to the periphery of the tundish, etc.) are usually installed between the tundish car and the surrounding work deck. As the tundish car moves between the casting position and the preheating position, the ends of the cables connected to the tundish car also move, so a guide holder (so-called Cableveyor (registered trademark)) is used to protect and guide the cables.

[0005] In order to more precisely control the casting process in a continuous casting facility, it may be necessary to arrange more cables between the tundish car and the work deck. However, the space between the tundish car and the work deck is generally narrow, so it may not be possible to arrange multiple guide holders horizontally. In this case, multiple guide holders are installed, but there is a concern that if one guide holder sags under its own weight, it may interfere with the cables held by other guide holders.

[0006] Therefore, the present disclosure describes a guide and holding device for cables and continuous casting equipment that can stably operate multiplexed guide and holding tools. [Means for solving the problem]

[0007] Example 1. One example of a cable guide and holding device includes a first guide and holder including a pair of bendable first long-chain members rotatably connecting a plurality of first units and a plurality of first connecting members connecting the pair of first long-chain members, the first guide and holder configured to guide and hold the first cables in the space between the pair of first long-chain members; a pair of bendable second long-chain members rotatably connecting a plurality of second units and a plurality of second connecting members connecting opposing second units of the pair of second long-chain members, the second guide and holder configured to guide and hold the second cables in the space between the pair of second long-chain members; and one or more restricting members provided on the first guide and holder. The first guide and holder is positioned outside the second guide and holder so as to overlap with the second guide and holder. The one or more restricting members are configured to restrict one of the first guide holder and the second guide holder from contacting the other when it hangs down. In this case, when the first and second guide holders are overlapped and multiplexed, the restricting member provided on the first guide holder restricts one guide holder from contacting the other guide holder when it hangs down. This prevents one guide holder from interfering with cables held by the other guide holder. This allows the multiplexed guide holders to operate stably.

[0008] Example 2. In the device of Example 1, the one or more restricting members may include a base portion extending so as to protrude outward from the first guide retainer in the width direction of the first guide retainer, and a bent portion bent from the tip of the base portion and extending from the first guide retainer toward the second guide retainer. In this case, the base portion is interposed between one of the hanging guide retainers and the other guide retainer. Therefore, the hanging of one of the guide retainers is restricted by the base portion. In addition, the bent portion is located to the side of the hanging one of the guide retainers. Therefore, the movement of the other guide retainer relative to the one of the guide retainers in the width direction is restricted by the bent portion. Therefore, the restricting member can prevent the hanging of one of the guide retainers from interfering with cables of the other guide retainer, while also making it possible to position the other guide retainer relative to the one of the guide retainers in the width direction.

[0009] Example 3. Another example of a cable guide and holding device includes a first guide and holding tool including a pair of bendable first long-chain members rotatably connecting a plurality of first units and a plurality of first connecting members connecting the pair of first long-chain members, and configured to guide and hold the first cables in the space between the pair of first long-chain members; a second guide and holding tool including a pair of bendable second long-chain members rotatably connecting a plurality of second units and a plurality of second connecting members connecting opposing second units of the pair of second long-chain members, and configured to guide and hold the second cables in the space between the pair of second long-chain members; and one or more restricting members provided on the second guide and holding tool. The first guide and holding tool is positioned outside the second guide and holding tool so as to overlap with the second guide and holding tool. The one or more restricting members are configured to restrict one of the first guide holder and the second guide holder from contacting the other when the first guide holder and the second guide holder hang down, thereby achieving the same effects as those of the device of Example 1.

[0010] Example 4: In the device of Example 3, one or more of the restricting members may include a base portion extending so as to protrude outward from the second guide / retainer in the width direction of the second guide / retainer, and a bent portion bending and extending from the tip of the base portion so as to extend from the second guide / retainer toward the first guide / retainer. In this case, the same effects as those of the device of Example 2 can be obtained.

[0011] Example 5: In the device of Example 2 or Example 4, the one or more restraining members may include a plurality of restraining members arranged side by side in the longitudinal direction of the first guide holder or the second guide holder, the plurality of restraining members including a plurality of first restraining members arranged near both ends of the first guide holder or the second guide holder and a plurality of second restraining members arranged between the plurality of first restraining members, and the width of the base portions of the plurality of first restraining members may be wider than the width of the base portions of the plurality of second restraining members. In this case, the plurality of restraining members can restrain the sagging of one guide holder toward the other guide holder over a relatively wide range in the longitudinal direction. This allows the multiplexed guide holders to operate more stably. Also, in this case, the sagging of one guide holder and its contact with the other guide holder is initially restrained by the relatively wide restraining member when the one guide holder sags toward the other guide holder, and thereafter is restrained by the relatively narrow restraining member. Therefore, when one guide holder starts to hang down, the focus is on preventing the other guide holder from interfering with the cables, and after the restricting member is placed between the one guide holder and the other guide holder, the positioning of the other guide holder relative to the one guide holder is performed by the bent portion, making it possible to more effectively prevent interference with cables and position the guide holders relative to each other.

[0012] Example 6: In any of the devices of Examples 1 to 5, the one or more restricting members may include a plurality of restricting members arranged side by side in the longitudinal direction of the first guide / holding device or the second guide / holding device. In this case, the plurality of restricting members can restrict the sagging of one guide / holding device toward the other guide / holding device over a relatively wide range in the longitudinal direction. This allows the multiplexed guide / holding devices to operate more stably.

[0013] Example 7: In the device of Example 6, the multiple restricting members may be arranged over an area of 50% or more of the entire length of the first guide holder or the second guide holder. In this case, the multiple restricting members can restrict the sagging of one guide holder toward the other guide holder over a wider range in the longitudinal direction. This allows the multiplexed guide holders to operate more stably.

[0014] Example 8: The device of any of Examples 1 to 7 may further include a guide support member configured to support and guide the second guide holder along the horizontal direction, and the second guide holder may further include a plurality of rollers rotatably attached to the pair of second long chain members and configured to roll on the guide support member. In this case, the hanging portion of the second guide holder located inside the first guide holder is supported by the guide support member. In addition, the second guide holder moves on the guide support member by the rollers. Therefore, it is possible to move the second guide holder stably.

[0015] Example 9. In any of the devices of Examples 1 to 8, the first guide holder and the second guide holder each include a movable end configured to be movable along the horizontal direction, and one end of the first cable extends so as to protrude outward from the movable end of the first guide holder in the width direction of the first guide holder, and one end of the second cable extends so as to protrude outward from the movable end of the second guide holder in the width direction of the second guide holder. In this case, one end of the cable held by the second guide holder protrudes to the side of the second guide holder located inside the first guide holder. Therefore, if a support member were provided to support the first guide holder from below, the legs of the support member would interfere with one end of the cable during movement of the tundish car. However, in Example 9, the sagging of one guide holder toward the other guide holder is restricted by a restricting member. Therefore, the restricting member functions as a support member for the first guide holder. Therefore, it is possible to stably operate the multiplexed guide holders without providing a separate support member for supporting the first guide holder.

[0016] Example 10: In any of the apparatuses of Examples 1 to 9, one end of the first guide holder and one end of the second guide holder may be connected to a traveling carriage configured to hold a tundish in a continuous casting facility and travel between a casting position and a preheating position. The cables and guide holders used in continuous casting facilities are quite heavy, and there is a concern that the operation of the continuous casting facility may be affected if a dangling guide holder interferes with the cables. However, in Example 10, a restricting member restricts the dangling of one guide holder toward the other guide holder. Therefore, the multiplexed guide holders operate stably, thereby stabilizing the operation of the continuous casting facility.

[0017] Example 11: An example of continuous casting equipment includes the apparatus of any one of Examples 1 to 10, a tundish configured to store molten metal, a mold configured to cool and mold the molten metal supplied from the tundish into a predetermined shape, and a traveling carriage configured to hold the tundish and travel between a casting position and a preheating position. One end of the first guide holder and one end of the second guide holder are connected to the traveling carriage. In this case, the same effects as those of the apparatus of Example 1 can be obtained. [Effects of the Invention]

[0020] In the following description, the same elements or elements having the same functions will be designated by the same reference numerals, and redundant explanations will be omitted. Note that in this specification, when referring to the top, bottom, right, and left of a figure, the directions of the reference numerals in the figure will be used as the reference.

[0021] [Continuous casting equipment] First, the configuration of a continuous casting equipment 100 will be described with reference to Fig. 1. The continuous casting equipment 100 includes a ladle 101, a tundish 102, a mold 103, a slab support roll 104, a tundish car 105 (traveling carriage), a work deck 106, a supply source 107, and a guide and holding device 1.

[0022] The ladle 101 is a container that stores molten metal (molten steel) M. The tundish 102 is located below the ladle 101 and is configured to store the molten metal M that flows out from a nozzle 101a provided on the bottom wall of the ladle 101.

[0023] The mold 103 is disposed below the tundish 102. The mold 103 is configured to cool the molten metal flowing out from a nozzle 102a provided on the bottom wall of the tundish 102 and form it into a predetermined shape. The slab support rolls 104 are configured to transport the slab S pulled out of the mold 103 while cooling it.

[0024] The tundish car 105 is configured to hold the tundish 102. The tundish car 105 is equipped with a plurality of wheels 105a that are configured to be able to run on rails R provided on a floor surface FL. Therefore, the tundish car 105 can run between a casting position and a preheating position while holding the tundish 102. For example, the casting position may be set near one end of the rails R, and the preheating position may be set near the other end of the rails R.

[0025] When the tundish car 105 is in the casting position, the tundish 102 is located below the ladle 101, as shown in Fig. 1. When the tundish car 105 is in the preheating position, the tundish 102 is located near a preheating device (not shown). At the preheating position, the tundish 102 is preheated by the preheating device in order to prevent a temperature drop of the molten metal when high-temperature molten metal is supplied to the tundish 102 and to prevent cracks and the like caused by thermal expansion of the tundish 102.

[0026] The work deck 106 is provided on the floor surface FL so as to be located to the side of the rail R. The work deck 106 is configured to be movable over the work deck 106 so that an operator can perform maintenance on the continuous casting equipment 100. As illustrated in FIG. 1, the upper surface of the work deck 106 may be set at approximately the same height as the upper surface of a movable deck 105c that is provided on the tundish car 105 via a support member 105b. In this case, an operator can easily move between the work deck 106 and the movable deck 105c.

[0027] The supply source 107 is a supply source for various equipment necessary for the operation of the continuous casting equipment 100. The supply source 107 may be mounted on the work deck 106 as illustrated in FIG. 1 , or may be installed on the floor surface FL. The supply source 107 may be connected to, for example, cables necessary for the continuous casting operation (e.g., electrical wiring, piping for hydraulic oil of the hydraulic drive system, piping for gas supply around the tundish, etc.). The supply source 107 may be, for example, a power source, a hydraulic oil supply source, or a gas supply source.

[0028] [Guiding and holding device] Next, the configuration of the guiding and holding device 1 will be described with reference to Figures 1 to 8. As illustrated in Figure 1, the guiding and holding device 1 is disposed between a tundish car 105 and a work deck .

[0029] The guide and retaining device 1 includes a support portion 2 (guide support member), an outer guide and retaining tool 10 (first guide and retaining tool), and an inner guide and retaining tool 20 (second guide and retaining tool).

[0030] The support unit 2 includes a support base 2a, a plurality of support columns 2b, and a pair of rails 2c. The support base 2a may be fixed to the work deck 106, for example. In other words, the support base 2a does not move. The plurality of support columns 2b are provided on the support base 2a so as to extend upward from the upper surface of the support base 2a. The pair of rails 2c extend horizontally along the direction of movement of the tundish car 105 (the extension direction of the rails R). The pair of rails 2c may have, for example, a substantially L-shaped cross section and be arranged to face each other.

[0031] The outer guide holder 10 is configured to guide and hold cables H1 (first cables) extending from a supply source 107 to the tundish car 105. As illustrated in Figures 2 and 4, the outer guide holder 10 is positioned outside the inner guide holder 20 so as to overlap the inner guide holder 20. The outer guide holder 10 includes a fixed end 10a and a moving end 10b.

[0032] The fixed end 10a is fixed to, for example, the support base 2a so as not to move. As illustrated in Figures 1, 2 and 4, one end of the cable H1 extends so as to protrude outward from the fixed end 10a in the width direction of the outer guide holder 10. That is, one end of the cable H1 protrudes laterally from the fixed end 10a and then extends toward the supply source 107.

[0033] The moving end 10b is fixed to, for example, a moving deck 105c and is configured to be movable horizontally together with the tundish car 105. As illustrated in Figures 1, 2 and 4, the other end of the cable H1 extends so as to protrude outward from the moving end 10b in the width direction of the outer guide holder 10. That is, the other end of the cable H1 protrudes laterally from the moving end 10b and then extends toward the tundish car 105.

[0034] As shown in Figures 2 to 7, the outer guide holder 10 may be configured to include a pair of long chain members 11 (first long chain members), a plurality of connecting members 12 (first connecting members), and a plurality of regulating members 13. The pair of long chain members 11 face each other and extend substantially parallel to each other in the extending direction of the rail R. The pair of long chain members 11 are bent so that the middle portions are U-shaped, with the moving end portions 10b positioned above the fixed end portions 10a.

[0035] The long chain member 11 may include, for example, a plurality of link plates 11a (first units) and a plurality of connecting pins 11b. The plurality of link plates 11a are aligned in a row along the longitudinal direction of the long chain member 11. Adjacent link plates 11a are rotatably connected to each other by connecting pins 11b. In other words, the long chain member 11 is configured such that the plurality of link plates 11a are rotatably connected to each other by connecting pins 11b, and is also bendable.

[0036] As illustrated in Figures 3 and 5 to 7, the multiple connecting members 12 connect the pair of long chain members 11 to each other so as to extend through the space V1 (see Figure 6) between the pair of long chain members 11. The connecting members 12 may be plate-shaped. The connecting members 12 may be provided with through holes 12a that hold the cables H1. That is, the cables H1 are guided and held by the outer guide holders 10 in the space V1 between the pair of long chain members 11.

[0037] The plurality of regulating members 13 are attached to the long chain member 11 so as to be aligned along the longitudinal direction of the long chain member 11. As illustrated in FIGS. 2 to 5, the plurality of regulating members 13 are attached to the long chain member 11 so as to be positioned between the outer guide retainer 10 and the inner guide retainer 20. As illustrated in FIGS. 2 and 4, the plurality of regulating members 13 may be attached to the long chain member 11 at predetermined intervals over an area of 50% or more of the entire length of the long chain member 11, or may be attached to the long chain member 11 at predetermined intervals over an area of 80% or more of the entire length of the long chain member 11, or may be attached to the long chain member 11 at predetermined intervals over the entire length of the long chain member 11. The regulating members 13 do not have to be attached to an area of the long chain member 11 near the moving end 10b.

[0038] 2 and 4, the plurality of regulating members 13 may include a plurality of regulating members 13A (first regulating members) and a plurality of regulating members 13B (second regulating members). The plurality of regulating members 13A may be arranged in a region of the long chain member 11 closer to the fixed end 10a and a region of the long chain member 11 closer to the moving end 10b. The plurality of regulating members 13B may be arranged in a region of the long chain member 11 between the plurality of regulating members 13A.

[0039] The restricting member 13 may be in the form of a plate extending in the width direction of the outer guide retainer 10. As illustrated in FIGS. 3, 5, and 7, the restricting member 13 may include a base portion 13a and a bent portion 13b. The base portion 13a may extend so as to protrude outward from the outer guide retainer 10 in the width direction of the outer guide retainer 10. The width of the base portion 13a of the restricting member 13A may be set wider than the width of the base portion 13a of the restricting member 13B. The bent portion 13b may be bent and extend from the tip of the base portion 13a so as to extend from the outer guide retainer 10 toward the inner guide retainer 20.

[0040] 1, the inner guide holder 20 is configured to guide and hold the cables H2 (second cables) extending from the supply source 107 to the tundish car 105. The inner guide holder 20 includes a fixed end 20a and a moving end 20b.

[0041] The fixed end 20a is fixed to, for example, the support base 2a so as not to move. As illustrated in Figures 1, 2 and 4, one end of the cable H2 extends so as to protrude outward from the fixed end 20a in the width direction of the inner guide holder 20. That is, one end of the cable H2 protrudes laterally from the fixed end 20a and then extends toward the supply source 107.

[0042] The moving end portion 20b is fixed to, for example, the moving deck 105c, and is configured to be movable in the horizontal direction together with the tundish car 105. As illustrated in Figures 1, 2 and 4, the other end portion of the cable H2 extends so as to protrude outward from the moving end portion 20b in the width direction of the inner guide holder 20. That is, the other end portion of the cable H2 protrudes laterally from the moving end portion 20b and then extends toward the tundish car 105.

[0043] As shown in Figures 2 to 5 and 8, the inner guide holder 20 may be configured to include a pair of long chain members 21 (second long chain members), a plurality of connecting members 22 (second connecting members), and a plurality of rollers 23. The pair of long chain members 21 face each other and extend substantially parallel to each other in the extending direction of the rail R. The pair of long chain members 21 are bent so that the middle portions are U-shaped, with the moving end portions 20b positioned above the fixed end portions 20a.

[0044] The long chain member 21 may include, for example, a plurality of link plates 21a (second units) and a plurality of connecting pins 21b. The plurality of link plates 21a are aligned in a row along the longitudinal direction of the long chain member 21. Adjacent link plates 21a are rotatably connected to each other by connecting pins 21b. In other words, the long chain member 21 is configured such that the plurality of link plates 21a are rotatably connected to each other by connecting pins 21b, and is also bendable.

[0045] As illustrated in Figures 3, 5, 7 and 8, the multiple connecting members 22 connect the pair of long chain members 21 to each other so as to extend through a space V2 (see Figure 8) between the pair of long chain members 21. The connecting members 22 may be plate-shaped. The connecting members 22 may be provided with through holes 22a (see Figures 3 and 5) that hold the cables H2. That is, the cables H2 are guided and held by the inner guide holder 20 in the space V2 between the pair of long chain members 21.

[0046] 2 to 5 and 8, the rollers 23 are rotatably attached to the long chain member 21 so as to be aligned along the longitudinal direction of the long chain member 21. As illustrated in FIG. 2, the rollers 23 may be attached to a region between the bent portion of the long chain member 21 and the moving end 20b when the tundish car 105 is in the casting position.

[0047] The rollers 23 are configured to roll on the rail 2c, as illustrated in Figures 1 to 3. That is, when the rollers 23 roll on the rail 2c, the portion of the inner guide holder 20 on the moving end 20b side is supported by the rail 2c (support portion 2) and guided along the horizontal direction.

[0048] [Effect] According to the above example, when the tundish car 105 is in the casting position (see FIG. 2), the portion of the outer guide fixture 10 on the moving end 10b side sags toward the inner guide fixture 20. However, since the restricting member 13 is provided on the long chain member 11 so as to be positioned between the outer guide fixture 10 and the inner guide fixture 20, the restricting member 13 restricts the sagging of the portion of the outer guide fixture 10 on the moving end 10b side. Therefore, as illustrated in FIGS. 2 and 3, the portion of the outer guide fixture 10 on the moving end 10b side does not come into contact with the inner guide fixture 20. On the other hand, when the tundish car 105 is in the preheating position (see FIG. 4), the portion of the inner guide fixture 20 on the fixed end 20a side sags toward the outer guide fixture 10. However, since the restricting member 13, which is easily positioned between the outer guide holder 10 and the inner guide holder 20, is provided on the long chain member 11, the sagging of the portion of the inner guide holder 20 on the fixed end 20a side is restricted by the restricting member 13. Therefore, as illustrated in FIGS. 4 and 5, the portion of the inner guide holder 20 on the fixed end 20a side does not come into contact with the outer guide holder 10. In this way, the restricting member 13 is configured to restrict the outer guide holder 10 and the inner guide holder 20 from contacting the other when they sag. This prevents one guide holder from interfering with the cables held by the other guide holder. This allows for stable operation of multiplexed guide holders.

[0049] According to the above example, restricting member 13 may include base portion 13a and bent portion 13b. In this case, base portion 13a is interposed between one hanging guide holder and the other hanging guide holder. Therefore, the hanging of one guide holder is restricted by base portion 13a. Furthermore, bent portion 13b is located to the side of one hanging guide holder. Therefore, movement of the other guide holder relative to one guide holder in the width direction is restricted by bent portion 13b. Therefore, restricting member 13 makes it possible to position one guide holder relative to one guide holder in the width direction while preventing interference of the other guide holder with cables due to the hanging of the other guide holder.

[0050] According to the above example, multiple regulating members 13 may be attached to the long chain member 11 so as to be aligned along the longitudinal direction of the long chain member 11. In this case, the multiple regulating members 13 can regulate the sagging of one guide holder toward the other guide holder over a relatively wide range in the longitudinal direction. This allows the multiplexed guide holders to operate more stably.

[0051] According to the above example, the plurality of regulating members 13 may be attached to the long chain member 11 at predetermined intervals over an area of 50% or more of the total length of the long chain member 11. In this case, the plurality of regulating members 13 can regulate the sagging of one guide holder toward the other guide holder over a wider range in the longitudinal direction. This allows the multiplexed guide holders to operate more stably.

[0052] According to the above example, the width of base portion 13a of restricting member 13A may be set wider than the width of base portion 13a of restricting member 13B. In this case, when one guide holder hangs down toward the other guide holder, contact with the other guide holder is restricted by relatively wide restricting member 13A at the beginning, and then by relatively narrow restricting member 13B. Therefore, when one guide holder hangs down, the focus is on preventing the other guide holder from interfering with cables. After restricting member 13 is between the one guide holder and the other guide holder, the other guide holder is positioned relative to the one guide holder by bent portion 13b. This makes it possible to more effectively prevent interference with cables and position the guide holders relative to each other.

[0053] According to the above example, the rollers 23 roll on the rail 2c, so that the portion of the inner guide holder 20 on the moving end 20b side may be supported by the rail 2c (support portion 2) and guided along the horizontal direction. In this case, the hanging portion of the inner guide holder 20 is supported by the rail 2c (support portion 2). Also, the inner guide holder 20 moves on the rail 2c by the rollers 23. Therefore, the inner guide holder 20 can be moved stably.

[0054] According to the above example, the other end of the cable H2 may protrude laterally from the moving end 20b. In this case, if a support member were provided to support the outer guide holder 10 from below, similar to the support portion 2 of the inner guide holder 20, the leg of the support member would interfere with the other end of the cable H2 when the moving end 20b moves in conjunction with the movement of the tundish car 105. However, in the above example, the sagging of one guide holder toward the other guide holder is restricted by the restricting member 13. Therefore, the restricting member 13 functions as a support member for the outer guide holder 10. Therefore, it is possible to stably operate the multiple guide holders without providing a separate support member for the outer guide holder 10.

[0055] Incidentally, the cables H1, H2 and guide holders 10, 20 used in the continuous casting equipment 100 are quite heavy, and there is a concern that if a dangling guide holder interferes with the cables, it may affect the operation of the continuous casting equipment 100. However, according to the above example, the dangling of one guide holder toward the other guide holder is restricted by the restricting member 13. Therefore, the multiplexed guide holders operate stably, and the operation of the continuous casting equipment can also be stabilized.

[0056] [Variations] The disclosure in this specification should be considered to be illustrative in all respects and not restrictive. Various omissions, substitutions, modifications, etc. may be made to the above examples without departing from the scope and spirit of the claims.

[0057] (1) The tundish car 105 may be configured to stop at a slag discharge position in addition to the casting position and the preheating position. A slag discharge pot may be provided near the slag discharge position. At the slag discharge position, the molten metal and slag remaining in the tundish 102 may be discharged into the slag discharge pot.

[0058] (2) The installation position of the guide and holding device 1 is not particularly limited, and it may be installed in a location other than the support base 2a (for example, on the floor surface FL).

[0059] (3) One or more restricting members 13 may be provided for one long chain member 11 .

[0060] (4) The restricting member 13 may be provided on the inner guide retainer 20. In this case, similar to the above example, the bent portion 13b may extend while bending from the base portion 13a toward the outer guide retainer 10, which is the other guide retainer. [Explanation of symbols]
