Hereinafter, an embodiment of an elevator vibration-proof structure according to the present invention will be described with reference to the accompanying drawings.
First embodiment
FIG. 1 shows an elevator machine room to which an elevator vibration-proof structure according to the present invention is applied.

  In the machine room 4 partitioned at the uppermost part of the hoistway 2, a hoisting machine 5 around which a rope 3 for hanging a car (not shown) is wound is installed. A vibration isolating structure 20 is assembled on the floor 8 of the machine room 4, and the hoisting machine 5 is mounted via the vibration isolating structure 20.

In this embodiment, the vibration isolating structure 20 is configured as follows so that it is not necessary to use a fastening element such as a bolt as shown in FIG.
FIG. 2 shows a support base 21, a vibration isolation member 22, and a vibration isolation base 23 that constitute the vibration isolation structure 20. In FIG. 2, the support base 21, the vibration isolation member 22, and the vibration isolation base 23 are shown in a state where they are disassembled in the vertical direction in order to make the characteristic portions easy to understand. Further, in order to install the hoisting machine 5, at least one set of structures in which the support base 21, the vibration isolation member 22, and the vibration isolation base 23 are overlapped is necessary on the left and right sides, but FIG. 2 shows only one side. Yes.

In this embodiment, H-shaped steel is used for the support base 21 and the vibration isolation base 23 as a structural member. The support base 21 is fixed by some method without being fixed by bolts or the like, and is placed on the floor.
The vibration isolator 22 is disposed between the support base 21 and the vibration isolator 23. The anti-vibration member 22 is formed by sandwiching a thick plate-like anti-vibration member 24 between upper and lower fixing plates 25a and 25b. The fixing plates 25a and 25b have shapes that engage with and regulate the flange portion 21a of the support base 21 and the flange portion 23a of the vibration isolation base 23, respectively.

  In the embodiment of FIG. 2, the lengths and widths of the fixing plates 25a and 25b correspond to the lengths and widths of the flange portions 21a and 23a, and the longitudinal edges of the fixing plates 25a and 25b, respectively. A convex portion 26 is formed on the portion, and a convex portion 27 is formed on the edge in the width direction.

  As described above, the fixing plates 25a and 25b of the vibration isolation member 22 are formed with the convex portion 26 in the longitudinal direction and the convex portion 27 in the width direction as the coupling portions. When the vibration member 22 and the vibration isolation table 23 are overlapped, the convex portions 26 and 27 serve as guides for the flange portions 21a and 23a that overlap the fixing plates 25a and 25b, respectively, and at the same time, a function that regulates the positional deviation from occurring. Demonstrate. This eliminates the need for bolts and nuts as in the prior art. Therefore, when installing the hoisting machine 5, the work space necessary for tightening the bolts and nuts is not required, and the installation area of the hoisting machine 5 can be saved.

  Further, in the present embodiment, there is an advantage that the bolt holes and the nuts need not be processed in the fixing plates 25a and 25b of the vibration isolation member 22 because the bolts and nuts are unnecessary.

  Next, FIG. 3 shows another modification of the vibration isolating structure. In this vibration isolating structure 30, holes 31 are formed at the four corners of the fixing plates 25 a and 25 b of the vibration isolating member 22. A stud 32 is attached to the flange portion 21 a of the support base 21 as a convex portion that fits into these holes 31. The pair of vibration isolating members 22 is placed on the support base 21 so that the studs 32 are fitted in the holes 31 of the fixing plate 25 b below the vibration isolating member 22. Although not shown in FIG. 3, a similar stud is also provided in the H-shaped steel as the vibration isolation table 23, and a hole formed in the fixing plate 25 a on the upper side of the vibration isolation member 22 in this stud. The anti-vibration table 23 may be installed so as to be fitted to 31.

It is only necessary to pile up the support base 21, the vibration isolation member 22, and the vibration isolation base 23, and there is no need for fixing with bolts and nuts as in the prior art.

Second embodiment
Next, FIG. 4 shows the vibration isolating structure 34 of the elevator hoisting machine according to the second embodiment.
The second embodiment is an embodiment in which the support base 21, the vibration isolation table 23 and the vibration isolation member 22 are coupled using a coupling fitting 35. The same H-shaped steel as in the first embodiment is used for the support base 21 and the vibration isolation base 23, but the vibration isolation member 22 has a vertical fixing plate without a convex portion as shown in FIG. 25a and 25b are used.

  The coupling fitting 35 is made of a fitting made of spring steel or the like, and the spring portion 35a bent in a U-shape is fitted to a portion where the flange portion 21a of the support base 21 and the lower fixing plate 25b of the vibration isolation member 22 overlap. And tightening force is generated. The flange portion 23 a of the vibration isolation table 23 and the upper fixing plate 25 a of the vibration isolation member 22 are similarly coupled using the coupling fitting 35.

  According to the anti-vibration structure 34 configured as described above, after the support base 21, the anti-vibration member 22, and the anti-vibration base 23 are stacked, it is only necessary to fit the coupling fitting 35. There is no need for fixing with a nut, and workability is also good.

  Next, FIG. 6 shows a modification of the coupling fitting having a U-shaped spring portion. In this coupling fitting 40, a flange 40b is formed at the tip of both the U-shaped spring 40a. Further, each of the coupling fittings 40 is connected by a connection portion 41. In addition, the connection part 41 is a part for mutually engagingly regulating for the same purpose as the collar part 40b. In this case, two anti-vibration members 22 are used for one support base 21, and the interval between the coupling fittings 40, 40 corresponds to the length of the anti-vibration member 22.

  According to the coupling fitting 40 configured as described above, the flange portion 40b is provided at the tip of the coupling bracket 40, and the flange portion 40b and the connection portion 41 are connected to the flange portion 12a of the support base 21 and the vibration isolation member 22. The lower fixing plate 25a can be engaged to prevent relative displacement between the two. Although not shown in FIG. 6, the coupling fitting 40 is also used for coupling the prevention member 22 and the vibration isolation table 23.

  FIG. 7 shows still another modified example of the coupling fitting having the U-shaped spring portion. 7A is a plan view, and FIG. 7B is a cross-sectional view taken along the line AA in FIG. 7A. In the case of this coupling fitting 42, both the U-shaped spring part 42a and the coupling fitting 40 of FIG. 7 are the same as the coupling fitting 40 of FIG. A hole 43 is formed through the lower fixing plate 25 a of the vibration isolation member 22 and the flange portion 21 a of the support base 21, and the flange portion 42 b of the coupling fitting 42 is engaged with the hole 43. Thereby, compared with the coupling fitting 40 of FIG.

  Next, FIG. 8 shows another modification of the coupling fitting. 8A is a plan view, and FIG. 8B is a side view of FIG. 8A. In the case of this coupling metal 44, the U-shaped spring part 44a is similar to the coupling metal 42 in FIG. 7 in that a collar part 44b is formed at the tip, but the difference is that the collar part 44 is related. The notch portion 45 to be joined is formed so as to be continuous with the lower fixing plate 25a of the vibration isolating member 21 and the flange portion 22a of the support base 22. As a result, as in the case of the coupling fitting 42 of FIG.

  Furthermore, FIG. 9 shows the modification of another coupling | bonding metal fitting. In this coupling metal 44, a bent handle portion 46 is formed instead of providing a collar portion. According to such a coupling metal 44, the removal tool can be engaged with the handle portion 46, so that there is an advantage that it is easy to remove the coupling metal 44.
