  • JP S54-13153 A discloses features falling under the preamble of claim 1. JP 2007/008693 A is further prior art.
  • the stopper bolt mounting seat is disposed centrally on the rubber vibration isolator, making the rubber vibration isolator construction complicated, which has led to cost increases.
  • the diameter of the rubber vibration isolator is increased by an amount proportionate to the aperture to ensure that damping properties are equal to a rubber vibration isolator that does not have the aperture.
  • the rubber vibration isolator upper plate and lower plate are increased by an amount proportionate to the increase in the rubber vibration isolator, enlarging the supporting apparatus.
  • the movement-restricting stopper bolt is a separate part from the bolts that fix the rubber vibration isolator upper plate to the base bearing, it is necessary to form the aperture through which the stopper bolt is passed on the base bearing.
  • the present invention aims to solve the above problems and an object of the present invention is to provide an elevator hoisting machine supporting apparatus that enables simplification and downsizing of a rubber vibration isolator construction and that can reduce drilling for mounting on a hoisting machine base by enabling movement of the hoisting machine to be restricted using a spacer that is fixed to an upper seat plate of a rubber vibration isolator, and that connects the rubber vibration isolator and the hoisting machine base.

  • the rubber vibration isolator does not constitute a movement-restricting mechanism, the construction of the rubber vibration isolator can be simplified, enabling cost reductions and downsizing to be achieved.
  • the spacer which transfers vibration of the hoisting machine to the rubber vibration isolator, serves also as a member that restricts movement of the hoisting machine by contacting an inner wall surface of the movement-restricting aperture

  • the movement-restricting plates 18 of the supporting apparatuses 10 that support the two end portions of the first side of the T shape of the hoisting machine base 3 are disposed such that groove depth directions of the U shapes of the notches 19 are parallel to the direction of projection of the second side of the T shape of the hoisting machine base 3 that projects outward from the first side, and such that the openings of the notches 19 are directed toward the projecting end of the second side of the T shape of the hoisting machine base 3.

  • vibration that is generated in the hoisting machine 1 is transferred to the rubber vibration isolators 11 by means of the hoisting machine base 3 and the spacers 16.
  • the vibration is absorbed by the rubber material 12 of the rubber vibration isolators 11, preventing the vibration from propagating to the machinery bases 5.
  • the members above the supporting apparatuses 10, i.e., the hoisting machine 1 that is fixed to the hoisting machine base 3 shakes significantly.
  • the hoisting machine base 3 and the spacers 16 that are fixed to the hoisting machine base 3 move horizontally in synchrony with the hoisting machine 1.
  • Motive force in the horizontal direction of the spacers 16 acts on the rubber material 12 by means of the upper seat plate 15, deforming the rubber material 12.
  • the spacers 16 contact inner wall surfaces of the semicircular bottom portions of the notches 19 of the movement-restricting plates 18, and the motive force in the horizontal direction of the hoisting machine 1 is transferred to the machinery bases 5 by means of the spacers 16, the movement-restricting plates 18, the mounting bolts 23a, and the lower seat plates 13.
  • the motive force in the horizontal direction of the hoisting machine 1 does not act to deform the rubber material 12 after the spacers 16 come into contact with the inner wall surfaces of the semicircular bottom portions of the notches 19.
  • the hoisting machine 1 rotates in a horizontal plane, torque from the hoisting machine 1 acts on the rubber material 12 by means of the spacers 16 and the upper seat plates 15, deforming the rubber material 12. If the torque from the hoisting machine 1 is greater than a set value, the spacer 16 comes into contact with the inner wall surface of the semicircular bottom portion of the notch 19 in at least one supporting apparatus 10 of the supporting apparatuses 10 that support the hoisting machine base 3 at three points. Thus, the torque from the hoisting machine 1 does not act to deform the rubber material 12 after the spacer 16 comes into contact with the inner wall surface of the semicircular bottom portion of the notch 19.
  • the motive force from the hoisting machine 1 acts on the rubber material 12 by means of the spacers 16 and the upper seat plates 15, deforming the rubber material 12. If the vertical motive force from the hoisting machine 1 is greater than a set value, the hoisting machine base 3 or an upper seat plate 15 contacts a movement-restricting plate 18. Thus, the motive force from the hoisting machine 1 does not act to deform the rubber material 12 after the hoisting machine base 3 or the upper seat plate 15 contacts the movement-restricting plate 18.
  • the supporting apparatuses 10 can thereby restrict horizontal, vertical, and rotational movement of the hoisting machine 1.
  • vibrational force such as from an earthquake acts on the hoisting machine 1, and the hoisting machine 1 moves horizontally or vertically, or rotates, because the supporting apparatuses 10 prevent the transfer of forces that would deform the rubber material 12 excessively, the amount of deformation in the rubber material 12 is suppressed, preventing situations that could lead to damage or breakage.
  • situations such as the rubber material 12 deforming significantly, and being damaged or broken, and the hoisting machine 1 tipping over, can be prevented.
  • the supporting apparatuses 10 constitute a movement-restricting mechanism that restricts horizontal, vertical, and rotational movement of the hoisting machine 1 using spacers 16 that are disposed so as to stand at central axial positions of the upper seat plates 15 of the rubber vibration isolators 11, and that are fixed to the hoisting machine base 3.
  • the vibration-proofing mechanism and the movement-restricting mechanism are coaxial, suppressing increases in radial dimensions of the supporting apparatuses 10, and enabling downsizing.
  • the present supporting apparatuses 10 are installed in place of existing supporting apparatuses that do not include a movement-restricting mechanism, situations such as the supporting apparatuses 10 interfering with the walls 7 of the machine room are prevented.
  • the supporting apparatuses 10 use spacers 16 that are fixed to the upper seat plates 15 and fixed to the hoisting machine base 3 in the movement-restricting mechanism, the only bolt passage apertures that are formed on the hoisting machine base 3 in order to mount the supporting apparatuses 10 to the hoisting machine base 3 are bolt passage apertures for fastening the spacers 16.
  • the present supporting apparatuses 10 are installed in place of existing supporting apparatuses that do not include a movement-restricting mechanism, the supporting apparatuses 10 can simply be installed using bolt passage apertures that are formed on the hoisting machine base 3 in order to mount the existing supporting apparatuses to the hoisting machine base 3. As a result, no additional drilling is required, improving installation workability of the supporting apparatuses 10.
  • the set values of the motive force in the horizontal direction and torque in the horizontal plane at which the spacers 16 contact the wall surfaces of the bottom portions of the notches 19 can be set freely by adjusting the groove width of the notches 19, i.e., the diameter of the semicircular bottom portions.
  • the set value of the vertical motive force at which the movement-restricting plates 18 contact the upper seat plates 15 or the hoisting machine base 3 can also be set freely by adjusting the gaps between the movement-restricting plates 18 and the upper seat plates 15, and the gaps between the movement-restricting plates 18 and the hoisting machine base 3.
  • Embodiment 1 three points of the hoisting machine base 3 are supported on the machinery bases 5 by means of the supporting apparatuses 10, but it is not necessary to dispose the supporting apparatuses 10 at all three points of the hoisting machine base 3, and horizontal, rotational, and vertical movement can still be restricted if supporting apparatuses 10 are disposed at two points such that the groove directions of the notches 18 are in reverse directions, and a supporting apparatus that does not include a movement-restricting mechanism is disposed at a remaining point.
  • the hoisting machine base is rectangular, four corners of the hoisting machine base may be supported by the machinery bases 5 by means of supporting apparatuses, but it is not necessary to use the present supporting apparatus 10 in all of the supporting apparatuses.
  • Horizontal, rotational, and vertical movement can still be restricted if supporting apparatuses 10 are disposed at two points such that the groove directions of the notches 18 are in reverse directions, and supporting apparatuses that do not include a movement-restricting mechanism are disposed at two remaining points, for example.
