Description

  The present invention relates to a bearing jig, and relates to a bearing jig that can be used for lifting and transporting bearing parts. In particular, the present invention relates to a bearing jig suitable for lifting and transporting non-annular bearing parts such as arcs and semicircles. For example, the half ring type of a two-part bearing used in a continuous casting machine The present invention relates to a bearing jig suitable for lifting and transporting an outer ring or the like. The present invention also relates to a bearing jig device including two bearing jigs.

  Conventionally, there is a bearing jig described in JP-A-11-101245 (Patent Document 1). This bearing jig is used for lifting a cage having two annular portions. This bearing jig has an integral structure, and has a ring portion for locking the string-like member and two cage locking portions.

  In this bearing jig, the one retainer engaging portion is engaged with a recess formed in one annular portion of the retainer, while the other retainer engaging portion is engaged with the other annular portion of the retainer. It engages with a recess formed in the part. After the string is locked to the ring portion, the cage locked to the two cage locking portions is lifted by lifting the ring portion with the string.

  By the way, in the continuous casting machine of steel, a two-part bearing may be arrange | positioned at the collar part of a saddle-type roll, and the two-part bearing may be provided with a half ring type outer ring | wheel. Here, unlike a ring-shaped outer ring, a herb ring type outer ring cannot be passed through a through-hole and is not easily lifted by a string, so it is usually carried by a human hand. Here, when the two-split bearing is large, the outer ring is several tens of kilometers, so that it is very difficult for the workers of the steel equipment to carry, and there is a problem that the carrying work is dangerous.

  However, the conventional bearing jig has a problem that the herb ring type outer ring cannot be lifted. Furthermore, in the conventional bearing jig, it is indispensable to form a recess for lifting in the product, so that the manufacturing cost of the product is improved and the performance of the product may be lowered. In addition, the beauty of the product is also impaired.

  Hereinafter, the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a schematic view of the bearing jig according to the first embodiment of the present invention when viewed from the front.

  The bearing jig (hereinafter simply referred to as a jig) includes a main body member 1 and an arm portion 5, and the arm portion 5 includes a first arm 2 and a second arm 3. The main body member 1 includes a flat plate portion 11 having a substantially rectangular cross section made of metal, an eyebolt 12, and a welded portion 13. The ring 15 of the eyebolt 12 constitutes a locking part. As shown in FIG. 1, the eyebolt 12 extends from the surface 14 on one side of the flat plate portion 11 in the normal direction. The bottom surface 16 of the end portion of the eyebolt 12 opposite to the ring 15 side is in contact with the surface 14 on one side of the flat plate portion 11. The welded portion 13 has an annular structure. The welded portion 13 is melted into the outer peripheral portion of the end portion opposite to the ring 15 side of the shaft portion of the eyebolt 12 and the upper surface portion of the flat plate portion 11. The welded portion 13 connects the eyebolt 12 to the flat plate portion 11.

  As shown in FIG. 1, the first arm 2 extends in a direction away from the eyebolt 12 from one end portion in the longitudinal direction of the flat plate portion 11, and the second arm 3 is the other end portion in the longitudinal direction of the flat plate portion 11. Extends away from the eyebolt 12. The first arm 2 is the same as the second arm 3. The first arm 2 overlaps the second arm 3 in the longitudinal direction of the flat plate portion 11.

  The first arm 2 is made of a metal material. The first arm 2 has a base portion 21, a first rod-like portion 22, and a third rod-like portion 23. The base portion 21 is made of a metal square, and extends from the flat plate portion 11 in the normal direction of the surface 14 on the one side. The first rod-like portion 22 extends in the width direction of the flat plate portion 11 having a substantially rectangular cross section from the end portion of the base portion 21 opposite to the flat plate portion 11 side. The first rod-like portion 22 is detachably connected to the base portion 21. Further, the third rod-like portion 23 extends from the base portion 21 in the width direction. The third rod-like portion 23 is located at the first rod-like portion 22 with an interval in the normal direction, and the flat plate portion 11 is also located at an interval in the normal direction. The third rod-like portion 23 has a male screw portion on the outer peripheral surface of one end portion thereof, and the base portion 21 has a plurality of substantially identical screw holes spaced from each other in the extending direction of the base portion 21 (the normal direction). have. The screw hole of the base portion 21 into which the male screw of the third rod-like portion 23 is screwed can be selected as appropriate. Therefore, the third rod-like portion 23 can be attached to a plurality of locations of the base portion 21 in a detachable state.

  The second arm 3 is made of a metal material. The second arm 3 has a base 31, a second rod-shaped portion 32, and a fourth rod-shaped portion 33. The base portion 31 is made of square bar and extends from the flat plate portion 11 in the normal direction. The base 31 of the second arm 3 and the base 21 of the first arm 2 constitute a base of the arm. The second rod-like portion 32 extends in the width direction of the flat plate portion 11 having a substantially rectangular cross section from the end of the base portion 31 opposite to the flat plate portion 11 side. The second rod-like portion 32 is connected to the base portion 31 so as not to be detached. Further, the fourth rod-shaped portion 33 extends from the base portion 31 in the width direction. The fourth rod-shaped portion 33 is positioned at the second rod-shaped portion 32 with an interval in the normal direction, and the flat plate portion 11 is also positioned at an interval in the normal direction. The fourth rod-shaped portion 33 has a male screw portion on the outer peripheral surface of one end thereof, and the base portion 31 has a plurality of substantially identical screw holes spaced from each other in the extending direction of the base portion 31 (the normal direction). have. The screw hole of the base portion 31 into which the male screw of the fourth rod-shaped portion 33 is screwed can be selected as appropriate. Therefore, the fourth rod-shaped portion 33 can be attached to a plurality of locations of the base portion 31 in a detachable state.

  The first rod-like portion 22 is substantially the same as the second rod-like portion 32, and the third rod-like portion 23 is substantially the same as the fourth rod-like portion 33. The first to fourth rod-like portions 22, 23, 32, and 33 have a round bar shape and have substantially the same circular cross-sectional shape. As shown in FIG. 1, the first rod-like portion 22 and the second rod-like portion 32 overlap in the longitudinal direction of the flat plate portion 11. Further, as shown in FIG. 1, the place where the third rod-like portion 23 in the base 21 can be attached and detached and the place where the fourth rod-like portion 33 in the base 31 can be attached and detached overlap in the longitudinal direction of the flat plate portion 11. . Therefore, as shown in FIG. 1, the third rod-like portion 23 can be arranged so as to overlap the fourth rod-like portion 33 in the longitudinal direction of the flat plate portion 11. For this reason, in the jig of the first embodiment, there is a plane on which the first rod-like portion 22 and the second rod-like portion 32 can be substantially plane-symmetric. In the arrangement shown in FIG. 1, the entire jig is substantially plane-symmetric with respect to the plane.

  FIG. 2 is a schematic view of the jig viewed from the direction indicated by the arrow A in FIG. 1, and is a schematic view of the jig viewed from the side.

  As shown in FIG. 2, the eyebolt 12 extends from one end portion in the width direction of the flat plate portion 11 in the normal direction of the surface 14 on one side of the flat plate portion 11. The first arm 2 extends from the other end in the width direction of the flat plate portion 11 in a direction away from the eyebolt 12 in the normal direction. Further, the length of the first rod-shaped portion 22 is longer than the length of the third rod-shaped portion 23.

  1 and 2, reference numeral 40 indicates a half ring type outer ring of a two-part bearing that is disposed on a flange portion of a vertical roll of a continuous casting machine as an example of a suspended member. As shown in FIGS. 1 and 2, this jig holds the outer ring 40 in a state where the axial direction of the outer ring 40 matches the extending direction of the first to fourth rod-like portions 22, 23, 32, 33. It is like that.

  In the above configuration, the outer ring 40 is installed on a jig as follows, for example.

  That is, first, a string-like member such as a leather string is locked in the through hole 18 of the ring 15 of the eyebolt 12 of the jig, and the ring 15 is lifted by a lifting machine such as a crane via the string-like member. 15 is lifted to some extent upward in the vertical direction.

  After that, on the ring 15 side portion of the first rod-shaped portion 22 that cannot be attached to and detached from the base portions 21 and 31, a portion on one side of the center of the arc-shaped convex surface 29 (see FIG. 1) of the outer ring 40 is simultaneously placed. The part on the other side of the center of the arcuate convex surface 29 of the outer ring 40 is placed on the part of the second rod-like part 23 on the ring 15 side. As shown in FIG. 1, in this state, the most vertically lower portion 41 of the arc-shaped convex surface 29 of the outer ring 40 is lower in the vertical direction than the first and second rod-like portions 22 and 23. In addition, it is preferable to set a distance between the first rod-shaped portion 22 and the second rod-shaped portion 23. This is because the outer ring 40 can be stabilized on the first and second rod-like portions 22 and 32 and the outer ring 40 can be lifted safely. Further, when the outer ring 40 is placed in the spherical concave portion (not shown) of the axle box disposed in the collar portion of the saddle type roll, the outer ring 40 can be brought into contact with the concave portion, while the jig is placed in the concave portion. This is because it can be made non-contact and the jig can be easily detached from the outer ring 40.

  Subsequently, the third rod-like portion 23 is screwed into the screw hole of the base portion 21 that can hold the outer ring 40 between the first rod-like portion 22 and the third rod-like portion 23, and the fourth rod-like portion 33 is joined to the second rod-like portion 32. The fourth rod-shaped portion 33 is screwed into the screw hole of the base portion 31 where the outer ring 40 can be sandwiched. In this way, the outer ring 40 is installed on the jig.

  After that, the outer ring 40 is lifted upward in the vertical direction by lifting a string-like member such as a leather strap locked to the ring 15 upward in the vertical direction with a crane or the like. Further, the outer ring 40 is also moved in the horizontal direction by moving the jig in the horizontal direction with a crane or the like while the outer ring 40 is lifted upward in the vertical direction. Further, the outer ring 40 is lowered downward in the vertical direction by lowering a string-like member such as a leather strap locked to the ring 15 downward in the vertical direction with a crane or the like. In this way, the outer ring 40 is transported to the recess of the axle box.

  According to the said 1st Embodiment, it has the 1st and 2nd rod-shaped parts 22 and 32 located mutually spaced apart. Therefore, two portions of the suspended member such as the half ring type outer ring 40 can be supported by the respective ring 15 side portions of the first and second rod-like portions 22 and 32. Therefore, it is not necessary to form any lifting recess or the like on the suspended member, and the suspended member can be lifted.

  For example, as described above, when the suspended member is the half-ring type outer ring 40, the first rod-shaped part 22 is closer to the ring 15 side than the center of the arc-shaped convex surface 29 of the outer ring 40. While supporting the portion on the side, the portion on the ring 15 side of the second rod-shaped portion 32 supports the portion on the other side of the center of the arcuate convex surface 29 of the outer ring 40. In this state, the outer ring 40 can be lifted upward in the vertical direction by lifting a string-like member such as a leather strap locked to the ring 15 upward in the vertical direction with a crane or the like. Further, the outer ring 40 can be moved in the horizontal direction by moving the bearing jig in the horizontal direction with a crane or the like while the outer ring 40 is lifted upward in the vertical direction. Therefore, even the half-ring type outer ring 40 can be lifted and moved in the horizontal direction, and there is no need to form a lifting recess or the like in the outer ring 40.

  In addition, according to the first embodiment, the third rod-like portion 23 positioned closer to the ring 15 than the first rod-like portion 22 with the first and second rod-like portions 22 and 32 being spaced apart from each other, Since it has the 4th rod-shaped part 33 located in the ring 15 side rather than the 2nd rod-shaped part 32 in the state which spaced apart the rod-shaped part 22, the 2nd rod-shaped part 32, and the 3rd rod-shaped part 23, it is a half ring. A suspended member such as a type outer ring 40 can be sandwiched between the first rod-shaped portion 22 and the third rod-shaped portion 23 and can be sandwiched between the second rod-shaped portion 32 and the fourth rod-shaped portion 33. Therefore, the suspended member can be securely held, and the suspended member can be reliably and safely moved to a desired location.

  In addition, according to the first embodiment, there is a plane that can be substantially plane-symmetric with respect to the first rod-shaped portion 22 and the second rod-shaped portion 32, and the plane is substantially plane-symmetric with respect to the plane. The posture of the jig can be stabilized during lifting of the suspended member. Therefore, the suspended member can be moved to a desired location more reliably and safely.

  In the first embodiment, the first rod-shaped portion 22 and the second rod-shaped portion 32 are the same and arranged in parallel to each other. However, in the present invention, the first rod-shaped portion and the second rod-shaped portion The rod-shaped portion may not be the same, and the first rod-shaped portion and the second rod-shaped portion may not be arranged in parallel to each other.

  Even if the first rod-shaped portion and the second rod-shaped portion are not the same, and even if the first rod-shaped portion and the second rod-shaped portion are not arranged in parallel to each other, the first and second rod-shaped portions This is because the suspended member may be supported. Similarly, in the first embodiment, the third rod-shaped portion 23 and the fourth rod-shaped portion 33 are the same and arranged in parallel to each other. However, in the present invention, the third rod-shaped portion and The fourth rod-shaped portion may not be the same, and the third rod-shaped portion and the fourth rod-shaped portion do not have to be arranged in parallel to each other.

  Moreover, in the said 1st Embodiment, although the main body member 1 had the rectangular parallelepiped flat plate part 11, in this invention, the main body member does not need to have a rectangular parallelepiped flat plate. However, you may have flat plates other than a rectangular parallelepiped flat plate, such as a disc and a curved plate. The main body member of the present invention may not have a flat plate. For example, the main body member of the present invention may have a sphere or the like instead of the flat plate, and any three-dimensional manifold other than the flat plate may be used. You may have.

  Moreover, in the said 1st Embodiment, although the latching | locking part was the ring 15 of the eyebolt 12, in this invention, a latching | locking part may be a through-hole formed in the main body member. May be a hook provided in the main body member. In short, the locking portion may have any configuration as long as it can lock the string-like member and can be lifted.

  Moreover, in the said 1st Embodiment, although the said 1st rod-shaped part 22 was connected to the base 21 so that removal was not possible, you may connect the 1st rod-shaped part 22 to a base 21 so that removal is impossible by a fastening member. Alternatively, the first rod-like portion 22 may be a structure integrated with the base portion 21, and the first rod-like portion 22 may belong to the same continuous body as the base portion 21.

  In the first embodiment, the third and fourth rod-like portions 23 and 33 exist. However, in the present invention, the third and fourth rod-like portions do not exist and only the first and second rod-like portions exist. An existing configuration may be used.

  Further, in the first embodiment, only one ring 15 of the eyebolt 12 is provided and only one locking portion is present. However, in the present invention, two or more locking portions may be provided. It is also possible that the jig is lifted at two or more locations.

  In the first embodiment, the third and fourth rod-like portions 23 and 33 are detachable from the base portions 21 and 31, but in the present invention, at least the third rod-like portion and the fourth rod-like portion. One may be non-detachable from the base.

  Further, in the first embodiment, there are two first and second arms 2 and 3, and the first and second rod-like portions 22 and 32 are respectively connected to the first and second arms 2 and 3. The bases 21 and 31 were not removable. However, in the present invention, there is only one arm, and the only one arm has only one base having a plate-like shape and the like and a large surface area. At least one of the rod-like portions may be configured to be detachably fixed to a plurality of locations on the base portion having a large surface area. With such a configuration, the distance between the first rod-shaped portion and the second rod-shaped portion can be changed by changing the fixing position of at least one of the first and second rod-shaped portions. It is possible to cope with the suspended member, and the versatility can be greatly improved. Of course, even when there is only one arm and only one base, both the first and second rod-like parts may be detachable from the base. In the present invention, three or more arms may exist.

  In the first embodiment, there is a plane that can be substantially plane-symmetric with respect to the first rod-like portion 22 and the second rod-like portion 32, and the plane can be substantially plane-symmetric with respect to the plane. Even if there is a plane that can make the first rod-shaped portion and the second rod-shaped portion substantially plane-symmetric, and even if there is a plane that can make the first rod-shaped portion and the second rod-shaped portion substantially plane-symmetric, The entire jig may not be substantially plane-symmetric with respect to the plane.

  In the first embodiment, the bases 21 and 31 of the first and second arms 2 and 3 extend in the vertical direction when the ring 15 of the eyebolt 12 is lifted upward in the vertical direction. It was. However, in the present invention, when at least one base portion is lifted upward in the vertical direction, it does not have to extend in the vertical direction. For example, at least one base portion has an acute angle in the vertical direction. You may extend in the direction which makes.

  In the first embodiment, each of the first to fourth rod-shaped portions 22, 23, 32, 33 extends linearly. However, in the present invention, at least one rod-shaped portion is linear. It does not have to extend to. For example, in the present invention, at least one rod-like portion may be waved and extended, or the suspended member may be more easily locked by a wave recess. In this invention, each rod-shaped part may have any shape as long as it can lock the suspended member.

  In the first embodiment, each of the first to fourth rod-like portions 22, 23, 32, and 33 has a round bar shape with a circular cross section. In the present invention, the cross-section of at least one rod-like portion is used. The shape may be any closed curve shape other than a circle, such as a rectangle, a star, a triangle, a trapezoid, or a polygon.

  In the first embodiment, each of the first to fourth rod-like portions 22, 23, 32, 33 is made of only a metal material. However, in the present invention, at least one rod-like portion is made of rubber or the like.
