- 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.

Abstract
Description
- The present invention relates to an elevator hoisting machine supporting apparatus, and particularly relates to a hoisting machine supporting apparatus that restricts movement of a hoisting machine during an earthquake.
- In conventional elevator hoisting machine supporting apparatuses, a rubber vibration isolator is inserted between a base bearing and a machine beam, a rubber vibration isolator upper plate and the base bearing are fixed by bolts, a rubber vibration isolator lower plate and the machine beam are fixed by bolts, a stopper bolt mounting seat is fixed to the rubber vibration isolator lower plate by welding, etc., so as to be positioned centrally on the rubber vibration isolator, and a stopper bolt is mounted onto the stopper bolt mounting seat so as to pass through an aperture that is formed on the base bearing (see
Patent Literature 1, for example). - In conventional elevator hoisting machine supporting apparatuses, because the stopper bolt is inserted into the aperture that is formed on the base bearing in a loosely fitted state, when the hoisting machine moves horizontally, vertically, or rotationally, the shaft portion of the stopper bolt comes into contact with the aperture that is formed on the base bearing, or the head portion of the stopper bolt comes into contact with the base bearing, restricting horizontal, vertical, or rotational movement of the hoisting machine. Thus, excessive deformation does not occur to the rubber vibration isolator, preventing the occurrence of damage to and breakage of the rubber vibration isolator, and preventing tilting of the hoisting machine due to breakage, etc., of the rubber vibration isolator.
- Patent Literature 1: Japanese Patent Laid-Open No.
SHO 58-74485 (Gazette - In conventional elevator hoisting machine supporting apparatuses, 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.
- Because the aperture for installing the stopper bolt mounting seat is formed centrally on the rubber vibration isolator, 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. In addition, 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. In addition, in conventional supporting apparatuses, because 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.
- When attempting to install conventional supporting apparatuses in place of existing supporting apparatuses that do not have a mechanism that restricts horizontal, vertical, or rotational movement of the hoisting machine, interference with building walls occurs, requiring additional drilling, thereby reducing installation workability.
- 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.
- In order to achieve the above object, according to one aspect of the present invention, there is provided an elevator hoisting machine supporting apparatus including: a rubber vibration isolator that is configured by holding a rubber material between an upper seat plate and a lower seat plate, and that is disposed by mounting the lower seat plate to a flange of a machinery base; a fastening means that fastens the lower seat plate to the flange; a cylindrical spacer of which a first end is fixed to the upper seat plate and is disposed so as to stand on the upper seat plate such that an axial direction is aligned with a center of the rubber vibration isolator, and of which a second end is fixed to a hoisting machine base; and a movement-restricting plate that has a movement-restricting aperture, and that is fixed to the lower seat plate so as to extend between the upper seat plate and the hoisting machine base such that the spacer is inserted through the movement-restricting aperture in a loosely fitted state.
- According to the present invention, a movement-restricting aperture is formed on a movement-restricting plate that is fixed to a lower seat plate so as to extend between an upper seat plate and a hoisting machine base, and a spacer that links the upper seat plate and the hoisting machine base is inserted through the movement-restricting aperture in a loosely fitted state, to restrict movement of the hoisting machine. Thus, because 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.
- Because 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, an aperture for passage of a bolt to fasten the spacer is the only aperture for mounting that is formed on the hoisting machine base. Thus, if the present supporting apparatus is installed in place of an existing supporting apparatus that does not have a mechanism that restricts movement of the hoisting machine, because an aperture that is formed on the hoisting machine base for mounting the existing supporting apparatus can be reused, additional drilling is not required, improving installation workability. Because the vibration-proofing mechanism and the movement-restricting mechanism are coaxial, suppressing increases in radial dimensions of the supporting apparatus and enabling downsizing to be achieved, the present supporting apparatus will not interfere with building walls when being installed.

rubber vibration isolators 11 include: arubber material 12 that is formed into a cylindrical shape; a flat, rectangularlower seat plate 13 that is fixed to a lower surface of therubber material 12; and a flat, circularupper seat plate 15 that is fixed to an upper surface of therubber material 12. Penetratingapertures 14 for mounting are formed on four corners of thelower seat plate 13. Thespacers 16 are formed so as to have a cylindrical shape, and are fixed to theupper seat plate 15 by welding, etc., so as to be disposed so as to stand coaxially on a central axis of therubber material 12. An internalscrew thread portion 17 is formed at central axial position of thespacer 16 such that a threaded aperture direction is oriented in an axial direction. - The movement-restricting
plates 18 are formed so as to have a flat, rectangular shape, and have anotch 19 that functions as a movement-restricting aperture. Thenotches 19 are formed so as to have an aperture shape that has a groove width that is greater than the diameter of thespacer 16, that has an opening centrally on an edge portion of a first side of the movement-restrictingplates 18 at a first end, and that has a semicircular bottom portion at a second end. In addition, penetratingapertures 20 for mounting are formed at an edge portion of a side of the movement-restrictingplates 18 that faces the bottom portion of thenotches 19 so as to be spaced apart in a longitudinal direction of the side in question. -
Clip members 21 are formed so as to have an L shape that has abase portion 21a; and aclip portion 21b that projects outward from a first end in a thickness direction of thebase portion 21a, are formed such that apenetrating aperture 22 passes through thebase portion 21a in the thickness direction. Moreover, theclip members 21, mountingbolts nuts 24 constitute the fastening means. Shaft portions of themounting bolts 23a are longer than shaft portions of themounting bolts 23b. - The
rubber vibration isolators 11 are mounted onto theflanges 5a of themachinery bases 5, and are fixed to themachinery bases 5 by placing thebase portions 21a of theclip members 21 against lower surfaces of the four corners of thelower seat plate 13, sandwiching theflanges 5a between thelower seat plate 13 and theclip portions 21b, inserting themounting bolts penetrating apertures 22 that are formed on thebase portions 21a of theclip members 21 and thepenetrating apertures 14 that are formed on thelower seat plate 13, and securing themounting bolts nuts 24. The shaft portions of two of themounting bolts 23a pass outside theupper seat plate 15, and extend parallelly so as to face thespacer 16. - The movement-restricting
plates 18 are fixed to the twomounting bolts 23a by passing themounting bolts 23a through thepenetrating apertures 20, positioning the center of the semicircular bottom portion of thenotch 19 so as to be aligned with a central axis of therubber vibration isolator 11, and fastening pairs ofnuts 24 that are screwed onto the shaft portions of themounting bolts 23a so as to sandwich the movement-restrictingplate 18. Thespacers 16 are thereby accommodated inside thenotches 19 such that central axes thereof match the centers of the semicircular bottom portions ofnotches 19. In addition, the hoistingmachine base 3 is supported on themachinery bases 5 by means of the supportingapparatuses 10 by passing mounting bolts (not shown) through penetrating apertures (not shown) that are formed on the hoistingmachine base 3, and fastening them into the internalscrew thread portions 17. - Here, the movement-restricting
plates 18 of the supportingapparatuses 10 that support the two end portions of the first side of the T shape of the hoistingmachine base 3 are disposed such that groove depth directions of the U shapes of thenotches 19 are parallel to the direction of projection of the second side of the T shape of the hoistingmachine base 3 that projects outward from the first side, and such that the openings of thenotches 19 are directed toward the projecting end of the second side of the T shape of the hoistingmachine base 3. The movement-restrictingplate 18 of the supportingapparatus 10 that supports the projecting portion of the second side of the T shape of the hoistingmachine base 3 is disposed such that groove depth direction of the U shape of thenotch 19 is parallel to the direction of projection of the second side of the T shape of thehoisting machine base 3, and such that the opening of thenotch 19 is directed toward the first side of the T shape of the hoistingmachine base 3. - In addition, the
penetrating apertures 20 are formed into slots in which two ends of two parallel lines are linked by semicircles, and the movement-restrictingplates 18 are fixed by themounting bolts 23a so as to be adjusted in position such that central axes of thespacers 16 are positioned centrally in the semicircular bottom portions of thenotches 19. - Next, operation of the supporting
apparatuses 10 will be explained. - First, vibration that is generated in the hoisting
machine 1 is transferred to therubber vibration isolators 11 by means of the hoistingmachine base 3 and thespacers 16. The vibration is absorbed by therubber material 12 of therubber vibration isolators 11, preventing the vibration from propagating to themachinery bases 5. - If subjected to vibration due to an earthquake, for example, the members above the supporting
apparatuses 10, i.e., the hoistingmachine 1 that is fixed to the hoistingmachine base 3 shakes significantly. - Here, if the hoisting
machine 1 moves horizontally, the hoistingmachine base 3 and thespacers 16 that are fixed to the hoistingmachine base 3 move horizontally in synchrony with the hoistingmachine 1. Motive force in the horizontal direction of thespacers 16 acts on therubber material 12 by means of theupper seat plate 15, deforming therubber material 12. - If the motive force in the horizontal direction of the hoisting
machine 1 is greater than a set value, thespacers 16 contact inner wall surfaces of the semicircular bottom portions of thenotches 19 of the movement-restrictingplates 18, and the motive force in the horizontal direction of the hoistingmachine 1 is transferred to themachinery bases 5 by means of thespacers 16, the movement-restrictingplates 18, the mountingbolts 23a, and thelower seat plates 13. Thus, because therubber material 12 moves horizontally in synchrony with the hoistingmachine 1, the motive force in the horizontal direction of the hoistingmachine 1 does not act to deform therubber material 12 after thespacers 16 come into contact with the inner wall surfaces of the semicircular bottom portions of thenotches 19. - If the hoisting
machine 1 rotates in a horizontal plane, torque from the hoistingmachine 1 acts on therubber material 12 by means of thespacers 16 and theupper seat plates 15, deforming therubber material 12. If the torque from the hoistingmachine 1 is greater than a set value, thespacer 16 comes into contact with the inner wall surface of the semicircular bottom portion of thenotch 19 in at least one supportingapparatus 10 of the supportingapparatuses 10 that support the hoistingmachine base 3 at three points. Thus, the torque from the hoistingmachine 1 does not act to deform therubber material 12 after thespacer 16 comes into contact with the inner wall surface of the semicircular bottom portion of thenotch 19. - If the hoisting
machine 1 moves vertically, the motive force from the hoistingmachine 1 acts on therubber material 12 by means of thespacers 16 and theupper seat plates 15, deforming therubber material 12. If the vertical motive force from the hoistingmachine 1 is greater than a set value, the hoistingmachine base 3 or anupper seat plate 15 contacts a movement-restrictingplate 18. Thus, the motive force from the hoistingmachine 1 does not act to deform therubber material 12 after the hoistingmachine base 3 or theupper seat plate 15 contacts the movement-restrictingplate 18. - The supporting
apparatuses 10 can thereby restrict horizontal, vertical, and rotational movement of the hoistingmachine 1. Thus, even if vibrational force such as from an earthquake acts on the hoistingmachine 1, and the hoistingmachine 1 moves horizontally or vertically, or rotates, because the supportingapparatuses 10 prevent the transfer of forces that would deform therubber material 12 excessively, the amount of deformation in therubber material 12 is suppressed, preventing situations that could lead to damage or breakage. As a result, situations such as therubber material 12 deforming significantly, and being damaged or broken, and the hoistingmachine 1 tipping over, can be prevented. - It is no longer necessary to adopt special constructions such as embedding spacer bolt mounting seats centrally in the rubber vibration isolators in the supporting
apparatuses 10, as it was in conventional devices, enabling therubber vibration isolators 11 to be achieved by a simple construction, and also enabling downsizing and cost reductions. - The supporting
apparatuses 10 constitute a movement-restricting mechanism that restricts horizontal, vertical, and rotational movement of the hoistingmachine 1 usingspacers 16 that are disposed so as to stand at central axial positions of theupper seat plates 15 of therubber vibration isolators 11, and that are fixed to the hoistingmachine base 3. Thus, the vibration-proofing mechanism and the movement-restricting mechanism are coaxial, suppressing increases in radial dimensions of the supportingapparatuses 10, and enabling downsizing. As a result, if the present supportingapparatuses 10 are installed in place of existing supporting apparatuses that do not include a movement-restricting mechanism, situations such as the supportingapparatuses 10 interfering with the walls 7 of the machine room are prevented. - Because the supporting
apparatuses 10use spacers 16 that are fixed to theupper seat plates 15 and fixed to the hoistingmachine base 3 in the movement-restricting mechanism, the only bolt passage apertures that are formed on the hoistingmachine base 3 in order to mount the supportingapparatuses 10 to the hoistingmachine base 3 are bolt passage apertures for fastening thespacers 16. Thus, if the present supportingapparatuses 10 are installed in place of existing supporting apparatuses that do not include a movement-restricting mechanism, the supportingapparatuses 10 can simply be installed using bolt passage apertures that are formed on the hoistingmachine base 3 in order to mount the existing supporting apparatuses to the hoistingmachine base 3. As a result, no additional drilling is required, improving installation workability of the supportingapparatuses 10. - Here, 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 thenotches 19 can be set freely by adjusting the groove width of thenotches 19, i.e., the diameter of the semicircular bottom portions. The set value of the vertical motive force at which the movement-restrictingplates 18 contact theupper seat plates 15 or the hoistingmachine base 3 can also be set freely by adjusting the gaps between the movement-restrictingplates 18 and theupper seat plates 15, and the gaps between the movement-restrictingplates 18 and the hoistingmachine base 3. - Moreover, in
Embodiment 1 above, three points of the hoistingmachine base 3 are supported on themachinery bases 5 by means of the supportingapparatuses 10, but it is not necessary to dispose the supportingapparatuses 10 at all three points of the hoistingmachine base 3, and horizontal, rotational, and vertical movement can still be restricted if supportingapparatuses 10 are disposed at two points such that the groove directions of thenotches 18 are in reverse directions, and a supporting apparatus that does not include a movement-restricting mechanism is disposed at a remaining point. - If 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 thepresent supporting apparatus 10 in all of the supporting apparatuses. Horizontal, rotational, and vertical movement can still be restricted if supportingapparatuses 10 are disposed at two points such that the groove directions of thenotches 18 are in reverse directions, and supporting apparatuses that do not include a movement-restricting mechanism are disposed at two remaining points, for example. -
Figure 4 is a side elevation that shows an elevator hoisting machine supporting apparatus according toEmbodiment 2 of the present invention, andFigure 5 is a cross section that is taken along Line V - V inFigure 4 so as to be viewed in the direction of the arrows. - In
Figures 4 and 5 , arubber vibration isolator 11 is fixed to amachinery base 5 by sandwichingflanges 5a of themachinery base 5 between alower seat plate 13 andclip portions 21b ofclip members 21 at four corners of thelower seat plate 13, inserting mountingbolts 23a into penetratingapertures 22 that are formed onbase portions 21a of theclip members 21 and penetratingapertures 14 that are formed on thelower seat plate 13, and securing the mountingbolts 23a and nuts 24. - A movement-restricting
plate 18A is formed so as to have a flat, rectangular shape, a circular movement-restrictingaperture 25 that has a larger diameter than that of aspacer 16 is formed approximately centrally on the movement-restrictingplate 18A, and penetratingapertures 14 for mounting are formed on four corners of thelower seat plate 13. The movement-restrictingplate 18A is fixed to each of the mountingbolts 23a by passing the mountingbolts 23a through the penetratingapertures 20, positioning the center of the movement-restrictingaperture 25 so as to be aligned with a central axis of therubber vibration isolator 11, and fastening pairs ofnuts 24 that are screwed onto the shaft portions of the mountingbolts 23a so as to sandwich the movement-restrictingplate 18A. - Moreover, the rest of the configuration is configured in a similar or identical manner to that of
Embodiment 1 above. - In a supporting
apparatus 10A that is configured in this manner, if the motive force in the horizontal direction of the hoistingmachine 1 exceeds a set value, thespacer 16 also comes into contact with the inner wall surface of the movement-restrictingaperture 25 of the movement-restrictingplate 18A in at least one supportingapparatus 10A of supportingapparatuses 10A that support the hoistingmachine base 3 at three points. If the torque in a horizontal plane of the hoistingmachine 1 exceeds a set value, thespacer 16 also comes into contact with the inner wall surface of the movement-restrictingaperture 25 of the movement-restrictingplate 18A in at least one supportingapparatus 10A of supportingapparatuses 10A that support the hoistingmachine base 3 at three points. In addition, if the vertical motive force of the hoistingmachine 1 exceeds a set value, the movement-restrictingplates 18A contact theupper seat plates 15 or the hoistingmachine base 3. - Thus, in
Embodiment 2, a supportingapparatus 10A that includes a movement-restricting mechanism in addition to a vibration-proofing mechanism can also be achieved by a simple construction, enabling similar effects to those inEmbodiment 1 above to be achieved. - According to
Embodiment 2, because the movement-restrictingplates 18A are supported by four mountingbolts 23a, the rigidity of the movement-restricting construction by the movement-restrictingplates 18A is increased, enabling horizontal, vertical, and rotational movement of the hoistingmachine 1 to be restricted reliably. -
Figure 6 is a side elevation that shows an elevator hoisting machine supporting apparatus according toEmbodiment 3 of the present invention, andFigure 7 is a cross section that is taken along Line VII - VII inFigure 6 so as to be viewed in the direction of the arrows. - In
Figures 6 and 7 , a movement-restrictingplate 18B is formed so as to have a C shape in which a movement-restrictingportion 18b and a mountingportion 18c project outward from two ends of a web 18a in identical directions, aU-shaped notch 19 that has a groove width that is greater than a diameter of aspacer 16 is formed so as to have an opening at a longitudinal center of a projecting end of the movement-restrictingportion 18b, and penetratingapertures 20 for mounting are formed on the mountingportion 18c so as to be separated longitudinally. Here, the longitudinal direction is a direction that is perpendicular to two directions that include a facing direction between the movement-restrictingportion 18b and the mountingportion 18c, and a direction of projection of the movement-restrictingportion 18b and the mountingportion 18c from the web 18a. - A movement-restricting
plate 18B is fixed by fastening together with aflange 5a of amachinery base 5 by placing the mountingportion 18c against alower seat plate 13, positioning a center of a semicircular bottom portion of thenotch 19 so as to be aligned with a central axis of arubber vibration isolator 11, andfastening nuts 24 and mountingbolts 23a that are passed through penetratingapertures 22 that are formed onbase portions 21a ofclip members 21, penetratingapertures 14 that are formed on thelower seat plate 13, and penetratingapertures 20 that are formed on the mountingportion 18c. - Moreover, the rest of the configuration is configured in a similar or identical manner to that of
Embodiment 1 above. - In a supporting
apparatus 10B that is configured in this manner, if the motive force in the horizontal direction of the hoistingmachine 1 exceeds a set value, thespacer 16 also comes into contact with the inner wall surface of the semicircular bottom portion of thenotch 19 that is formed on the movement-restrictingportion 18b of the movement-restrictingplate 18B in at least one supportingapparatus 10B of supportingapparatuses 10B that support the hoistingmachine base 3 at three points. If torque in a horizontal plane of the hoistingmachine 1 exceeds a set value, thespacer 16 also comes into contact with the inner wall surface of the semicircular bottom portion of thenotch 19 that is formed on the movement-restrictingportion 18b of the movement-restrictingplate 18B in at least one supportingapparatus 10B of supportingapparatuses 10B that support the hoistingmachine base 3 at three points. In addition, if the vertical motive force of the hoistingmachine 1 exceeds a set value, the movement-restrictingportion 18b of the movement-restrictingplates 18B contact theupper seat plates 15 or the hoistingmachine base 3. - Thus, in
Embodiment 3, a supportingapparatus 10B that includes a movement-restricting mechanism in addition to a vibration-proofing mechanism can also be achieved by a simple construction, enabling similar effects to those inEmbodiment 1 above to be achieved. - According to
Embodiment 3, because the mountingportion 18c of the movement-restrictingplate 18B is fixed to theflange 5a of themachinery base 5 together with thelower seat plate 13 of therubber vibration isolator 11, the number ofnuts 24 is reduced, improving installation workability. - Moreover, in each of the above embodiments, machine bases are fixed to a floor of a machine room, but in the case of machine-roomless elevators, the machine bases are disposed so as to span across a hoistway. In other words, the machine bases are fixed to a building so as to span the hoistway.
