Description

  Embodiments described herein relate generally to a jack-up jig, an elevator car, and a vibration isolation member replacement method.

  Conventionally, elevator cars (car compartments) have floor members, ceiling members, side wall members, etc. fixed to an outer frame-shaped frame (an assembly of frame members) formed of steel such as angle steel (L-shaped steel). To be formed. For example, a vibration isolating member formed of a rubber member or the like may be sandwiched between the floor member and the frame member that supports the floor member. For example, the vibration isolation member is configured to prevent vibration generated during lifting operation from being transmitted to the floor member via the frame member. The anti-vibration member is made of, for example, hard rubber. However, if the time from installation becomes long, for example, the elastic force decreases due to plastic deformation, material deterioration, etc., and aged deterioration occurs. It is desirable. When replacing the vibration isolation member, for example, using a jack-up jig or the like as disclosed in Patent Document 1, Patent Document 2, etc., the floor seat is raised (jacked up) with respect to the frame member, The vibration isolating member can be replaced by enlarging the gap between the member and the frame member. Then, the floor member is lowered (jacked down) to return the car to the original state.

  Conventionally, each time the vibration isolator is replaced, the jack-up jig must be brought to the work site, and after completion of the work, the jack-up jig must be collected, and equipment preparation and transportation for the work is carried out. It took effort. Therefore, if a jackup jig having a simple structure that can eliminate the need to bring in and collect the vibration isolating member for each replacement operation is obtained, it is meaningful that the labor for the replacement operation can be reduced.

The jackup jig of the embodiment includes, for example, a first screw member, a second screw member, and a support plate. The first screw member can be disposed on the upper surface of the frame member that supports the floor member of the elevator with the vibration isolating member interposed therebetween. The second screw member can be screwed with the first screw member and can contact the lower surface of the floor member. The support plate is pivotable about the first screw member as a pivot axis, and is at least two of the same interval as the arrangement interval of at least two fastening holes arranged in the extending direction of the frame member to fix the vibration isolating member to the frame member. It can be fastened together by a fastening member having two openings and fixing the vibration isolating member .

  Hereinafter, a jack-up jig, an elevator car, and a vibration isolation member replacement method according to embodiments will be described in detail with reference to the drawings. The constituent elements in the embodiments include those that can be easily replaced by those skilled in the art or that are substantially the same, and the present invention is not limited to the following embodiments.

  An example of an elevator car to which the jack-up jig of the embodiment can be applied is shown in FIG. The car 10 moves up and down a hoistway installed in a building (not shown) such as a building or a condominium and moves between landings provided on each floor. The car 10 has, for example, a box shape in which a user or a luggage can be placed, and the outer shape is formed by combining steel materials such as angle steel (L-shaped steel). In the case of FIG. 1, for example, a frame member 10a that forms a bottom surface portion, a frame member 10b that forms a side wall portion, a frame member 10c that forms a ceiling portion, and the like are joined by welding or the like. The frame member 10a forming the floor portion supports the floor member 12 made of metal, resin, or the like. Similarly, the frame member 10b supports a side wall member (not shown) made of metal, resin, etc., and the frame member 10c supports a ceiling member (not shown) made of metal, resin, etc. Form. In addition, an openable and closable car door (not shown) that allows a user and luggage to enter and exit is disposed on a part of the side wall portion formed by the frame member 10b, instead of the side wall member.

  Between the floor member 12 and the frame member 10a that supports the floor member 12, for example, a vibration isolating member 14 formed of a rubber member (for example, hard rubber) or the like is disposed. The vibration isolating member 14 reduces, for example, the vibration generated during the raising / lowering operation of the car 10 from being transmitted to the floor member 12 via the car 10 (frame member 10a). The anti-vibration member 14 is, for example, a block-shaped member whose upper and lower surfaces are flat, such as a prism or a cylinder, and the lower surface side is in contact with the upper surface of the frame member 10a (the surface facing upward on the valley side of the angle steel). It arrange | positions and the upper surface side contacts the lower surface of the floor member 12. FIG. The vibration isolation member 14 is disposed at a plurality of positions on the frame member 10a. In the case of FIG. 1, one anti-vibration member 14 is provided for the frame member 10a on the short side (the left and right frame members 10a in FIG. 1), and the frame member 10a on the long side (the upper and lower frame members 10a in FIG. 1). Two examples are shown. The number of the vibration isolation members 14 may be appropriately adjusted in accordance with the length of the frame member 10a and the balance of the weight applied to the floor surface. For example, the anti-vibration member 14 may be disposed two by two on each side or one by one. There may be three or more sides (frame member 10a). Further, the number of the vibration isolation members 14 may be the same on each side or may be different.

  The jack-up jig 16 of the present embodiment is disposed on the upper surface of the frame member 10a in the vicinity of each vibration isolation member 14. The jack-up jig 16 pushes up the floor member 12 with respect to the frame member 10a when the vibration isolating member 14 needs to be replaced, and creates a gap between the upper surface of the frame member 10a and the lower surface of the floor member 12. By enlarging, the upper surface of the vibration isolation member 14 and the lower surface of the floor member 12 are separated, and the vibration isolation member 14 can be replaced. The jack-up jig 16 according to the present embodiment can be attached to and detached from the frame member 10a (car 10). However, after the jack-up jig 16 is arranged once, it can be placed at that position. Therefore, when the vibration isolating member 14 is replaced next time, the placed jackup jig 16 can be reused. The jack-up jig 16 has a structure that can be fixed to a part of the car 10, for example, one of the vibration isolating member 14, the frame member 10a, the floor member 12, and the like.

  Hereinafter, a specific configuration and an example of use of the jackup jig 16 will be described.

<Embodiment 1>
FIG. 2 is an explanatory diagram for explaining the configuration of the jack-up jig 16 according to the first embodiment, and shows both a side view and a top view.

  The jackup jig 16 includes a first screw member 18, a second screw member 20, and a support plate 22. The first screw member 18 is, for example, a male screw. As an example, the first screw member 18 can be a bolt with the screw shaft portion 18a facing upward. As shown in FIG. 3, the first screw member 18 can be disposed (contacted) on the upper surface of the frame member 10 a that supports the floor member 12 with the vibration isolating member 14 interposed therebetween, as shown in FIG. 3.

  The second screw member 20 is, for example, a female screw (for example, a nut) that can be screwed with the screw shaft portion 18a of the first screw member 18, and one end portion 20a is formed on the lower surface of the floor member 12 as shown in FIG. Abutment is possible. When the second screw member 20 is screwed around the first screw member 18 and moves in the removal direction, the floor member 12 is pushed up with respect to the frame member 10a, and the gap between the car 10 and the floor member 12 is enlarged. Thus, the vibration isolator 14 can be replaced. Further, when the second screw member 20 is screwed with respect to the first screw member 18 and moves in the screwing direction, the floor member 12 is lowered by its own weight, and the gap between the frame member 10a and the floor member 12 is reduced, and the floor member. 12 can be placed (supported) on the vibration isolating member 14, that is, the floor member 12 can be supported on the frame member 10a. The total length in the axial direction of the first screw member 18 and the second screw member 20 in a state in which the second screw member 20 is fastened to the screw shaft portion 18a is the same as that of the frame member 10a and the floor member 12. The second screw member 20 and the first screw member 18 are selected so as to be shorter than the gap H (see FIG. 3) formed when sandwiched between the two. On the contrary, when the second screw member 20 is screwed with respect to the first screw member 18 and moves in the removal direction, the total axial length of the first screw member 18 and the second screw member 20 is longer than the gap H. The floor member 12 is selected to be pushed up. Note that the second screw member 20 may be a screw member that can be screwed onto the first screw member 18 by applying an external force. For example, the outer shape of the second screw member 20 may be a general hexagonal nut shape that can be rotated with a tool such as a wrench, or a rectangular or cylindrical shape other than the hexagonal shape and can be rotated with a dedicated tool. May be.

  The support plate 22 is a thin plate-like member that can turn around the screw shaft portion 18a of the first screw member 18 as a turning shaft, and can be formed of a metal such as iron or stainless steel, a resin, or the like. The support plate 22 is a member for placing the jackup jig 16 on the car 10 after the vibration isolating member 14 is replaced. The support plate 22 can be engaged with any one of the vibration isolating member 14, the floor member 12, and the frame member 10a. The support plate 22 includes a through hole (not shown) through which the screw shaft portion 18a of the first screw member 18 can be inserted, and allows the support plate 22 itself to turn around the screw shaft portion 18a. Further, the support plate 22 includes, for example, two holes 24 for engaging (fixing) with the vibration isolating member 14, for example. Note that the two holes 24 formed in the support plate 22 have, for example, bolts 26 as fastening members whose separation distance P at the center position of the holes 24 is used when the vibration isolation member 14 is fixed to the frame member 10a. It is formed to be the same as the arrangement distance P0 of (screw hole 26a).

  A method for using the jackup jig 16 configured as described above (a method for replacing the vibration isolator 14) will be described with reference to FIGS. 3 and 4 show a vibration isolator 14 to be exchanged disposed between the frame member 10a and the floor member 12, and FIG. 6 shows a new anti-vibration member 14 that has been replaced. It is shown. Further, as shown in FIG. 3, the vibration isolating member 14 sandwiched between the frame member 10a and the floor member 12 has flange portions 14a bonded to the surface in contact with the frame member 10a and the surface in contact with the floor member 12, respectively. And screw fixing. The flange portion 14a is a plate-like member such as stainless steel or iron, and corresponds to a fixing screw hole 26a formed in the frame member 10a or the floor member 12 into which the bolt 26 is inserted when the vibration isolator 14 is fixed. An opening (not shown) is formed at the position to be. In addition, the flange part 14a may be integrally formed with the rubber member similar to the vibration isolating member 14.

  First, the jack-up jig 16 is disposed in the vicinity of the vibration isolating member 14 to be replaced that is sandwiched between the frame member 10a and the floor member 12, for example, on the left side of the anti vibration isolator 14 on the frame member 10a. . At this time, as shown in FIG. 3, the center position of the screw hole 26 a for the bolt 26 on the side close to the jack-up jig 16 among the bolts 26 that fix the vibration isolation member 14 and the center axis position of the second screw member 20. Is a distance P1. The distance between the center axis position of the second screw member 20 and the center position of the hole 24 on the support plate 22 closer to the second screw member 20 is a distance P2. And the jackup jig | tool 16 is arrange | positioned on the frame member 10a so that the distance P1 and the distance P2 may correspond (arrangement process). In order to make the distance P1 and the distance P2 coincide with each other, for example, a marking indicating the arrangement position of the jackup jig 16 may be provided on the frame member 10a. Further, for example, an uneven portion may be formed so as to be engaged with the frame member 10a and the jack-up jig 16 in place of the marking so that the alignment can be easily performed. As described above, the distance P between the center positions of the two holes 24 formed in the support plate 22 and the arrangement distance P0 of the screw holes 26a for the two bolts 26 are the same. Therefore, the distance P3 between the center position of the screw hole 26a of the bolt 26 far from the jackup jig 16 and the center axis position of the second screw member 20, the center axis position of the second screw member 20, and the second screw member. The distance P4 with the center position of the hole portion 24 on the side far from 20 coincides. The arrangement process of the jack-up jig 16 is similarly performed on all the vibration isolating members 14 arranged on the car 10.

  Next, the bolts 26 that fix the vibration isolator 14 to the frame member 10a and the floor member 12 are removed from the flange portion 14a while the jack-up jig 16 is disposed at the position shown in FIG. Note that the bolt 26 may be removed before the jack-up jig 16 is disposed. Subsequently, the second screw member 20 is screwed in the first direction with respect to the screw shaft portion 18a of the first screw member 18 and moved in the removal direction. That is, the frame member 10 a is stretched by the first screw member 18, and the floor member 12 is stretched by the second screw member 20. As a result, as shown in FIG. 4, the floor member 12 is pushed up in the direction of arrow A by the second screw member 20, and jacks up between the upper flange portion 14 a of the vibration isolation member 14 and the lower surface of the floor member 12. A gap Hu is formed (jack-up process). This jack-up process is similarly performed on all the vibration isolation members 14 arranged on the car 10.

  In this state, the vibration isolator 14 to be replaced can be extracted from between the frame member 10a and the floor member 12. With the vibration isolator 14 to be replaced removed, the support plate 22 of the jack-up jig 16 is, for example, 180 ° around the screw shaft portion 18a (see FIG. 4) of the first screw member 18 as shown in FIG. Turn. As described above, since the distance P1 = the distance P2 and the distance P3 = the distance P4, the two holes 24 of the support plate 22 rotated by 180 ° are respectively connected to the vibration isolation member 14 (flange portion 14a) by the frame member 10a. It corresponds to the two screw holes 26a for fixing to.

  Then, with the two holes 24 of the support plate 22 aligned with the positions of the two screw holes 26a for the bolts 26 (see FIG. 5), the new vibration isolator 14 is removed as shown in FIG. The vibration isolating member 14 is inserted into the same position as the position where the vibration isolating member 14 was mounted (exchange process). This replacement process is similarly performed on all the vibration isolation members 14 arranged in the car 10. In addition, since the new vibration-proof member 14 which is not deteriorated by plastic deformation or the like is thicker than the vibration-proof member 14 to be extracted, the jack-up gap Hu by the jack-up jig 16 is a new vibration-proof member. 14 is taken into consideration. In this state, the bolt 26 is inserted through the opening formed in the flange portion 14a and the hole portion 24 formed in the support plate 22 into the frame member 10a, and the bolt 26 is screwed into the screw hole 26a. That is, the flange portion 14a (vibration isolation member 14) and the support plate 22 are fastened together (engagement step). At this time, the bolt 26 on the frame member 10a side may be temporarily tightened. This engagement process is similarly performed on all the vibration isolation members 14 arranged on the car 10.

  Subsequently, the second screw member 20 of the jack-up jig 16 is screwed in a second direction opposite to the first direction and moved in the screwing direction. As a result, the floor member 12 descends with respect to the frame member 10a, the floor member 12 comes into contact with the vibration isolation member 14, and the floor member 12 is elastically supported by the vibration isolation member 14. That is, the relationship among the frame member 10a, the vibration isolating member 14, and the floor member 12 returns to the vibration isolating state (jack down process). This jack-down process is similarly performed on all the vibration isolating members 14 arranged in the car 10. Finally, the bolt 26 is inserted into the flange portion 14 a on the floor member 12 side and screwed into the screw hole of the floor member 12. By performing this operation on all the vibration isolation members 14 and fixing the floor member 12 side, a series of replacement operations of the vibration isolation members 14 is completed.

  At this time, the first screw member 18 is simply placed on the frame member 10a, and the second screw member 20 is not in contact with the floor member 12. Since it is fastened together with the flange portion 14a, the jack-up jig 16 is firmly fixed to the frame member 10a as a whole. Therefore, even when the car 10 is left in this state and the car 10 is normally operated, the jack-up jig 16 is not dropped or lost. Further, when the next vibration isolating member 14 is replaced, it is possible to carry out the jack-up operation using the jack-up jig 16 placed in the car 10 without bringing in a separate jack-up jig. The replacement work of the vibration isolation member 14 can be performed. In addition, after the work, the jack-up jig 16 can be placed in the car 10 again. As a result, it is not necessary to bring in or collect the jack-up jig every time work is performed, and the labor for replacing the vibration isolator 14 is reduced. Further, since the jack-up jig 16 is a simple, small and light jig composed of the first screw member 18, the second screw member 20, and the support plate 22, a plurality of jack-up jigs 16 can be placed in the car 10. A significant increase in jig cost is unlikely to occur. In addition, problems such as breaking the weight balance of the car 10 and interfering with other structures are unlikely to occur.

  In Embodiment 1 mentioned above, the example which jacks up the floor member 12 by arrange | positioning the jackup jig | tool 16 one by one with respect to all the vibration isolator members 14 arrange | positioned at the passenger car 10 was shown. In another embodiment, as long as the floor member 12 can be jacked up in parallel, it is not always necessary to use the jackup jig 16 for all the vibration isolation members 14. For example, in FIG. 1, the jack-up jig 16 may be disposed only on one of the frame members 10a (for example, the frame member 10a on the front side of the drawing) in which two vibration isolating members 14 are disposed. That is, the jack-up work may be performed with the jack-up jigs 16 (four in total) arranged one on each side. Moreover, in Embodiment 1 mentioned above, the example which fixes the support plate 22 to the frame member 10a by fastening together with the vibration proof member 14 was shown. In another embodiment, the support plate 22 may be directly fixed to the frame member 10a or the floor member 12, and similar effects can be obtained. The first screw member 18 is also fixed to the car 10 by fixing the support plate 22 to the flange portion 14a (vibration isolation member 14) or the like. Therefore, the jack-up operation and the jack-down operation are stabilized, and workability and safety are improved.

  FIG. 7 shows a modification of the jackup jig 16 of the first embodiment. As shown in FIG. 2, a hole 24 is formed in the support plate 22 of the jack-up jig 16 described above, but the support plate 22a of the jack-up jig 16A of the modification shown in FIG. Instead of the hole 24, a notch 24a is formed. As described above, when the hole 24 is formed in the support plate 22, as shown in FIG. 6, when the flange portion 14a and the support plate 22 are fastened together, the bolt 26 is completely removed. Then, after aligning the hole 24, the screw hole 26a (see FIG. 5), and the opening corresponding to the screw hole 26a formed in the flange portion 14a, it is necessary to screw in the bolt 26. In this case, since the support plate 22 cannot be removed unless the bolts 26 are completely removed, the holding reliability of the jackup jig 16 in the car 10 is high. On the other hand, as shown in FIG. 7, when the support plate 22 a includes the notch 24 a, the support plate 22 a can be attached to the screw shaft portion of the bolt 26 with the bolt 26 temporarily tightened against the screw hole 26 a. After mounting from the side, the bolt 26 can be tightened. As a result, as compared with the case where the support plate 22 is formed, positioning when the support plate 22a is fastened together becomes easy, and the workability for replacing the vibration isolating member 14 can be improved.

<Embodiment 2>
8 and 9 show the jack-up jig 16B of the second embodiment. The jack-up jig 16B of the second embodiment is the same in other basic configuration except that the shape of the support plate 22b is different from that of the first embodiment. Detailed description is omitted.

  As shown in FIGS. 8 and 9, the support plate 22b of the jack-up jig 16B is shorter than the jack-up jig 16 shown in FIG. 2 or the jack-up jig 16A shown in FIG. Has been. As shown in FIG. 9, the support plate 22b can turn around a screw shaft portion 18a (see, for example, FIG. 4) of the first screw member 18 as in the other embodiments. Further, the shapes of the first screw member 18 and the second screw member 20, the jack-up operation, and the jack-down operation are the same as those in the other embodiments, and the same effect can be obtained.

  In the case of the jack-up jig 16B, the support plate 22b is short, and, as shown in FIG. 9, the side close to the jack-up jig 16B among the bolts 26 for fixing the flange portion 14a on the frame member 10a side of the vibration isolator 14 The bolt 26 is engaged. On the other hand, it does not engage with the bolt 26 on the other side. Further, the support plate 22 of the jack-up jig 16 shown in FIG. 2 and the support plate 22a of the jack-up jig 16A shown in FIG. 7 are configured to engage with a pair of bolts 26 with the vibration isolating member 14 interposed therebetween. ing. Therefore, the support plate 22 and the support plate 22a are disposed between the frame member 10a and the vibration isolation member 14 (flange portion 14a), that is, below the vibration isolation member 14. Therefore, the gap H between the frame member 10a and the floor member 12 after the vibration isolator 14 is replaced is widened by the thickness of the support plate 22 (support plate 22a). That is, the height of the vibration isolating member 14 is increased. On the other hand, in the case of the jack-up jig 16B of the second embodiment, as shown in FIG. 9, the support plate 22b is inserted between the screw head of the bolt 26 on the side close to the jack-up jig 16B and the flange portion 14a. The bolts 26 are fastened together with the flange portion 14a.

  In this way, by using the short support plate 22b, the jack-up jig 16B allows the car 10 (vibration isolation member) even after the vibration isolation member 14 (flange portion 14a) is fixed by the other three bolts 26. 14) and workability is improved. Further, since the support plate 22b does not enter the lower side of the flange portion 14a, the gap H between the frame member 10a and the floor member 12 does not increase unlike the jack-up jigs 16 and 16A. That is, the height of the vibration isolation member 14 is not changed. Further, the jack-up jig 16B is made smaller than the jack-up jigs 16 and 16A, and it is possible to reduce the jig cost, the storage space, the ease of handling, and the like. In the jack-up jig 16B, the notch 24a described with reference to FIG. 7 may be provided instead of the hole 24, and the same effect as the jack-up jig 16A can be obtained.

<Embodiment 3>
FIG. 10 shows a jack-up jig 16C according to the third embodiment. The jack-up jig 16C according to the third embodiment has an end portion of the first screw member 18, that is, an end portion of the first screw member 18 on the side in contact with the frame member 10a (see FIG. 3), with the frame member 10a. A first contact plate member 28 that increases the contact area is provided. Similarly, a second contact plate member 30 that increases the contact area with the floor member 12 is provided at the end of the second screw member 20 on the side in contact with the floor member 12 (see FIG. 3). The configuration of the jack-up jig 16 </ b> C is basically the same as the configuration of the jack-up jig 16 of Embodiment 1 except that the first contact plate member 28 and the second contact plate member 30 are provided. Therefore, the same reference numerals are given to the same configurations, and detailed description thereof is omitted.

  The first contact plate member 28 is, for example, a plate-like member made of stainless steel or iron material, and can be set as appropriate as long as the shape is larger than the contact area of the first screw member 18 with the frame member 10a. It is. The first contact plate member 28 can be fixed to the first screw member 18 by, for example, welding. Similarly, the second contact plate member 30 is a plate-like member made of, for example, stainless steel or iron, and the shape may be rectangular or circular as long as it is larger than the contact area of the second screw member 20 with the floor member 12. It can be set as appropriate. The second contact plate member 30 can be fixed to the second screw member 20 by, for example, welding. When the floor member 12 is jacked up, the first contact plate member 28 increases the contact area with the frame member 10a and the second contact plate member 30 increases the contact area with the floor member 12. The stability of the lifting and lowering operation when jacking down is improved.

  When jacking up or down, the second contact member 30 fixed to the second screw member 20 slides on the lower surface of the floor member 12 because the second screw member 20 is screwed. become. That is, contact resistance is generated, and a large force may be required for screwing. Therefore, the second screw member 20 and the second contact plate member 30 are rotatably engaged, or a rotation mechanism is provided between the second screw member 20 and the second contact plate member 30, thereby The two-screw member 20 may be easily screwed.

  The first contact plate member 28 and the second contact plate member 30 can be mounted on the jack-up jig 16A shown in FIG. 7 or the jack-up jig 16B shown in FIG. be able to.

  In each of the above-described embodiments and modifications, the jack-up jig 16 (16A, 16B, 16C) is brought into the existing car 10 that does not include the jack-up jig when the vibration isolation member 14 is replaced. An example of use and detention was shown. In another embodiment, when the car 10 is newly constructed, the jack-up jig 16 (16A, 16B, 16C) may be installed together with the vibration isolating member 14.
