Specification

Elevator vibration isolator technology

[0001] The present invention relates to an elevator in which a car and a counterweight are suspended via a rope in a hoistway of a building, for example, and in particular, a structure of a vibration isolator that blocks vibration transmitted to a hitch plate. About.

Background art

[0002] An elevator includes a driving rope for suspending a car and a counterweight in a hoistway of a building. The car and the counterweight are driven in the ascending and descending directions in the hoistway by driving the driving rope with a driving device.

In recent years, in order to efficiently use the internal space of a building, a machine room-less elevator has been developed that does not require a dedicated machine room in which a drive device is installed. For example, Japanese Patent Laid-Open No. 2 005-29344 discloses an example of a machine roomless elevator. As shown in FIG. 10, this type of machine room-less elevator has a pair of guide rails 2a, 2b for guiding the raising and lowering of the riding force 5 and a pair for guiding the raising and lowering of the counterweight 3 inside the hoistway 1. Guide rails 4a and 4b. The guide rails 2a, 2b, 4a, 4b stand vertically along the hoistway 1. Each guide rail 2a, 2b, 4a, 4b is supported on the wall surface of the hoistway 1 via a plurality of brackets (not shown).

[0004] A gantry 8 is installed on top of the guide rails 2a, 2b, 4a, 4b. The gantry 8 is composed of a plurality of support beams 7. The gantry 8 is placed horizontally on the support means 10 attached to the upper part of each guide rail 2a, 2b, 4a, 4b.

A driving device 12 is installed on the gantry 8. The drive device 12 has a traction sheave 13. A plurality of drive ropes 14 are wound around the traction sheave 13. The drive ropes 14 are aligned in parallel to each other and are guided downward from the trough sheave 13 to the ascending / descending path 1. One end of the drive rope 14 is connected to the first hitch plate 17. The other end of the drive rope 14 is connected to the second hitch plate 18. It is.

[0006] The car 5 and the counterweight 3 are suspended in the hoistway 1 via a drive rope 14. The car 5 and the counterweight 3 travel in the ascending or descending direction on the hoistway 1 when the traction sheave 13 of the driving device 12 rotates.

[0007] The first hitch plate 17 is horizontally supported on the upper part of one guide rail 2a for the car via a bracket 20. The second hitch plate 18 is supported horizontally on the top of the gantry 8.

[0008] When the operation of the elevator is started by the activation of the drive device 12, the drive device 12 vibrates. The vibration of the driving device 12 is transmitted from the gantry 8 to the wall surface of the hoistway 1 through the guide rails 2a, 2b, 4a, 4b, and causes noise of the elevator.

[0009] In order to improve this, in the conventional elevator, the vibration isolator 24 is interposed between the guide means 10 supported on each guide rail 2a, 2b, 4a, 4b and the gantry 8, respectively. The vibration isolator 24 blocks or moderates vibrations that are transmitted from the gantry 8 to the guide rails 2a, 2b, 4a, and 4b. Thereby, generation | occurrence | production of noise can be suppressed.

On the other hand, Japanese Patent Application Laid-Open No. 2001-31346 discloses an elevator in which a driving rope is connected to a car frame to which a car is fixed via a rod. The rod passes through the hitch plate attached to the force frame. A coil spring is stretched between the end of the rod and the hitch plate. The coil spring is for adjusting the tension of the drive rope.

[0011] A rubber vibration isolator is interposed between one end of the coil spring and the hitch plate.

. The anti-vibration material prevents the coil spring and hitch plate from rubbing against each other when the car moves up and down. Thereby, the vibration propagated between the coil spring and the hitch plate can be absorbed by the vibration isolator.

According to the elevator disclosed in Japanese Patent Application Laid-Open No. 2005-29344, the vibration generated by the driving device 12 is also transmitted to the driving rope 14 through the traction sheave 13. Therefore, the drive rope 14 vibrates during the operation of the elevator.

[0013] In general, the drive rope 14 is provided with a shirtle rod at one end and the other end, respectively. The shirtle rod penetrates the first and second hitch plates 17, 18 in the thickness direction. ing. A coil spring is attached to the end of the shirtle rod. The coil spring is sandwiched between the nut attached to the end of one shirtle rod and the first hitch plate 17 and between the nut attached to the end of the other shirtle rod and the second hitch plate. It is. Thus, the load applied to the drive rope is received by the first and second hitch plates 17 and 18 from the shirt rod to the coil spring.

[0014] According to this configuration, the vibration of the drive rope 14 is absorbed to some extent by the coil spring. Therefore, vibration transmitted from the drive rope 14 to the first and second hitch plates 17 and 18 is mitigated.

[0015] However, when the coil spring receives vibration from the driving rope 14 with a force, there is a concern that the coil spring may cause a surging phenomenon. Therefore, with the coil spring, the drive rope 14 force cannot block the vibrations transmitted to the first and second hitch plates 17 and 18, and a sufficient anti-vibration performance cannot be expected! /.

[0016] In particular, the second hitch plate 18 is attached to the support beam 7 supported by the guide rail 4b via the vibration isolator 24 in the gantry 8. Therefore, there is a concern that a resonance phenomenon between the vibration transmitted from the driving rope 14 to the second hitch plate 18 and the natural frequency of the support beam 7 occurs. Therefore, the vibration of the second hitch plate 18 is promoted, and there is a possibility that the anti-vibration performance is lowered.

[0017] According to the configuration disclosed in Japanese Patent Laid-Open No. 2001-31346, the coil spring that adjusts the tension of the driving rope is in contact with the vibration isolator. For this reason, the tension of the driving rope acts directly on the vibration isolator from the coil spring.

As a result, it is necessary to increase the spring constant of the vibration isolator in order to increase the load resistance of the vibration isolator and suppress local deformation. At the same time, since the mass applied to the vibration isolating material is reduced, the natural frequency of the vibration isolating system cannot be denied. Therefore, the vibration transmitted to the coil spring force hitch plate cannot be well blocked, and sufficient vibration isolation performance cannot be expected.

Disclosure of the invention

[0019] The object of the present invention is to accurately block vibration transmitted to the hoistway by the rope force, and to improve vibration proof performance. The object is to obtain an elevator vibration isolator that can be enhanced.

[0020] In order to achieve the above object, an elevator vibration isolator according to one aspect of the present invention includes a rope for suspending a passenger car and a counterweight in a hoistway; and a hitch to which an end of the rope is connected. A plate; and a support member for supporting the hitch plate in the hoistway. A vibration isolator is interposed between the hitch plate and the support member.

[0021] According to the present invention, the propagation of vibration between the hitch plate and the support member can be blocked by the vibration isolator. For this reason, the vibration applied to the rope during operation of the elevator becomes difficult to propagate to the hoistway, and the vibration isolation performance of the elevator can be improved.

Hereinafter, a first embodiment of the present invention will be described with reference to FIG. 1 and FIG. In the first embodiment, the same components as those of the conventional elevator shown in FIG. 10 are denoted by the same reference numerals, and the description thereof is omitted.

FIG. 1 and FIG. 2 disclose a configuration in which one end of the driving rope 14 is connected to, for example, a hitch portion located at the upper part of the guide rail 2a that guides the raising and lowering of the car. As shown in FIGS. 1 and 2, a bracket 20 is attached to the hitch portion of the guide rail 2a. The bracket 20 includes a first support member 30, a second support member 31, and a pair of reinforcing members 32a and 32b. The first support member 30 is fixed to the back surface of the guide rail 2a by means such as welding. The first support member 30 stands vertically along the guide rail 2a. The second support member 31 is fixed to the upper end portion of the first support member 30 by, for example, means such as welding. The second support member 31 maintains a horizontal posture orthogonal to the first support member 30. The reinforcing members 32a and 32b are attached between the first support member 30 and the second support member 31 so as to support the second support member 31 with a downward force.

A hitch plate 33 is disposed on the second support member 31. The second support member 31 and the hitch plate 33 each have a flat plate shape having four corners. The upper surface of the second support member 31 and the lower surface of the hitch plate 33 are substantially equal in size.

[0026] A coasting material 34 is interposed between the second support member 31 and the hitch plate 33. The elastic material 34 is an example of a vibration isolator, and is formed of a high molecular material having elasticity such as natural rubber, synthetic rubber, or urethane. The inertia material 34 has a flat plate shape having four corners. The inertia material 34 has an area that is the same as or slightly smaller than the area of the upper surface of the hitch plate 33 when viewed planarly. Furthermore, the inertia material 34 has a certain thickness.

As shown in FIG. 1, each of the plurality of drive ropes 14 includes a shirtle rod 36 at one end thereof. The shirtle rod 36 penetrates the second support member 31, the inertia material 34 and the hitch plate 33 and is connected to the hitch plate 33.

More specifically, the second support member 31, the coasting material 34 and the hitch plate 33 have a plurality of through holes 38, 39 and 40 through which the shackle rod 36 passes. Each drive rope 14 The shirtle rod 36 is inserted into the through holes 38, 39 and 40 from below the bracket 20. The upper part of the shirt rod 36 projects upward from the upper surface of the hitch plate 33.

As shown in FIG. 1, a coil spring 42 is attached to the upper part of each shirtle rod 36. The coil spring 42 surrounds the upper outer peripheral surface of the shirtle rod 36. First and second nuts 43a and 43b are screwed into the protruding ends of the shirt rods 36. The second nut 43b is a lock nut that prevents the first nut 43a from loosening. The coil spring 42 is sandwiched between the first nut 43a and the hitch plate 33. For this reason, the load applied to the shirt rod 36 from the drive rope 14 is received by the hitch plate 33 via the coil spring 42.

Further, the coil spring 42 urges the hitch plate 33 toward the second support member 31. As a result, the inertia material 34 is sandwiched between the hitch plate 33 and the second support member 31 by the urging force of the coil spring 42.

According to the first embodiment as described above, the vibration applied to the drive rope 14 from the drive device 12 during operation of the elevator is absorbed by the coil spring 42. Further, the vibration of the drive rope 14 is absorbed by elastic deformation of the elastic member 34 positioned between the hitch plate 33 and the second support member 31. Therefore, the vibration that tries to propagate the force of the driving rope 14 to the second support member 31 via the hitch plate 33 is surely blocked by the inertia material 34.

[0032] Therefore, the vibration from the drive rope 14 is difficult to propagate to the wall surface of the guide rail 2a that supports the bracket 20 having the second support member 31 and the hoistway 1 that supports the guide rail 2a. As a result, the noise of the elevator can be accurately suppressed.

[0033] The inertia material 34 only needs to have the same size as the upper surface of the hitch plate 33 when viewed planarly. For this reason, the space in the planar direction of the hitch plate 33 can be saved because it is not necessary to project the outer peripheral portion of the inertia material 34 outward from the outer peripheral edge of the hitch plate 33. As a result, if the dwarf material 34 interferes with the equipment and parts arranged around the hitch plate 33! /, There will be no inconvenience! /.

[0034] The free material 34 has the same area as the upper surface of the hitch plate 33.

Therefore, a sufficient contact area between the coasting material 34 and the hitch plate 33 can be secured, Accordingly, the thickness of the elastic material 34 can be reduced. Therefore, an increase in the space along the height direction of the hoistway 1 can be suppressed, and the space around the hitch plate 33 can be saved.

The coasting material 34 has a plurality of through holes 39 through which the shirt rope rods 36 of the respective drive ropes 14 pass. For this reason, the coasting material 34 does not move due to the vibration of the drive rope 14 and does not fall off from the second support member 31 at all times. The appropriate position between the second support member 31 and the hitch plate 33 is always the same. Retained. Therefore, a fixing means such as a bolt for fixing the inertia member 34 to the second support member 31 or the hitch plate 33 is unnecessary, and the mounting structure of the elastic member 34 can be simplified.

[0036] The present invention can be implemented with various modifications without departing from the gist of the invention which is not limited to the first embodiment described above.

[0037] FIG. 3 and FIG. 4 disclose a second embodiment of the present invention. In the second embodiment, the configurations of the second support member 31 and the hitch plate 33 are different from those of the first embodiment. The other configuration of the elevator is the same as that of the first embodiment.

As shown in FIGS. 3 and 4, a pair of first protrusions 45 a and 45 b are disposed on the upper surface of the second support member 31. The first protrusions 45a and 45b are blocks having a square shape when viewed in a plan view, and are fixed to the upper surface of the second support member 31 by means such as adhesion or welding. The first protrusions 45 a and 45 b are located at two corners located on the diagonal line among the four corners of the second support member 31.

[0039] A pair of second protrusions 46a and 46b are disposed on the lower surface of the hitch plate 33. The second protrusions 46a and 46b are blocks having a square shape when viewed in a plan view, and are fixed to the lower surface of the hitch plate 33 by means of adhesion or welding. The second protrusions 46 a and 46 b are located at two pairs of corners located on the diagonal line among the four corners of the hitch plate 33. The diagonal line connecting the first protrusions 45a and 45b and the diagonal line connecting the second protrusions 46a and 46b intersect each other.

[0040] As shown in FIG. 4, notches 47 are formed in four corners of the coasting material 34, respectively.

The notch 47 is for avoiding the first protrusions 45 a and 45 b of the second support member 31 and the second protrusions 46 a and 46 b of the hitch plate 33. Second support member 31 and hitch plate In a state where the coasting material 34 is sandwiched between the first projections 45 a and 45 b and the second projections 46 a and 46 b, the first projections 45 a and 45 b are caught by the notches 47 of the coasting material 34. As a result, the position of the inertia member 34 with respect to the second support member 31 and the hitch plate 33 is determined.

[0041] According to the second embodiment, the first protrusions 45a and 45b of the second support member 31 and the second protrusions 46a and 46b of the hitch plate 33 are cut out of the inertia material 34. You are stuck on. For this reason, it is possible to prevent the inertia member 34 from shifting between the second support member 31 and the hitch plate 33, and the inertia member 34 is determined in advance between the second support member 31 and the hitch plate 33. Can be held at a precise position. Therefore, it is possible to prevent the elastic material 34 from interfering with the shirt cloth 36 that penetrates the through hole 39 of the elastic material 34.

FIGS. 5 and 6 disclose a third embodiment of the present invention.

In the third embodiment, the weight 48 is installed on the hitch plate 33. The weight 48 is fixed to the upper surface of the hitch plate 33 by means of, for example, welding, adhesion, or fastening with bolts.

[0044] According to the third embodiment as described above, the mass added to the coasting material 34 due to the presence of the weight 48 increases, and the natural frequency of the vibration isolation system decreases. As a result, the vibration of the driving rope 14 that is about to be transmitted from the hitch plate 33 to the second support member 31 can be reliably blocked by the coasting material 34, and the vibration damping performance of the elevator is further improved.

The weight 48 of the third embodiment only needs to be firmly fixed to the hitch plate 33. Therefore, the method of fixing the weight 48 is not limited to means such as welding, adhesion, and fastening with bolts, and other fixing means can be employed.

[0046] Furthermore, it is desirable that the weight 48 has a shape that fits in an area surrounded by the outer peripheral edge of the hitch plate 33 when viewed in plan. In this way, the hoistway 1 need not be expanded in the horizontal direction, saving space.

[0047] If there is no possibility that the weight 48 on the hitch plate 33 and other devices in the hoistway 1 interfere with each other, the weight 48 is projected out of the outer peripheral edge of the hitch plate 33. It may be installed on the hitch plate 33 in such a posture.

[0048] The height L of the weight 48 is preferably set with the upper end position of the shirt rod 36 or the upper end position of the guide rail 2a as the upper limit. This way, the hoistway It is possible to save space without having to expand the overhead dimension of the upper end of 1.

[0049] In each of the embodiments described above, the inertia member 34 is formed as a single-piece structure having a size corresponding to the second support member 31 and the hitch plate 33. However, the present invention is not limited to this. For example, FIG. 7 discloses a coasting material 34 according to a fourth embodiment of the present invention.

[0050] The inertia material 34 of the fourth embodiment is configured by combining a plurality of divided pieces 34a. A semicircular cutout 50 is formed at the outer peripheral edge of each divided piece 34a. The split pieces 34a are arranged on the upper surface of the second support member 31 so that the cutout portions 50 face each other. The notches 50 of the adjacent divided pieces 34a cooperate with each other to form a through hole 38 through which the shirt rod 36 is passed.

[0051] The elastic member 34 having such a configuration is interposed between the second support member 31 and the hitch plate 33 in the same manner as in the first embodiment. The shirtle rod 36 is connected to the hitch plate 33 in a state of passing through the second support member 31, the through hole 38 of the inertia material 34 and the hitch plate 33.

[0052] In the fourth embodiment, the elastic member 34 is configured by combining a plurality of divided pieces 34a. For this reason, after the shirtle rod 36 is laid across the second support member 31 and the hitch plate 33, the split piece 34a is formed in the gap between the second support member 31 and the hitch plate 33. Can be plugged in. In other words, it is possible to interpose the inertia material 34 later between the second support member 31 and the hitch plate 33 in a state where the shirtle rod 36 is bridged.

[0053] FIG. 8 discloses a coasting material 34 according to a fifth embodiment of the present invention.

The fifth embodiment is different from the fourth embodiment in the shape of the notch 50 formed in each divided piece 34a. As shown in FIG. 8, the notch 50 of each divided piece 34a is a square. The cutout portions 50 of the adjacent divided pieces 34a form a through hole 38 through which the shirtle rod 36 is passed in cooperation with each other. Each through hole 38 has a square opening shape.

[0055] In the fourth and fifth embodiments, the force in which the stiffener 34 is configured by a combination of a plurality of divided pieces 34a is not limited thereto. For example, the hitch plate 33 may be composed of a combination of a plurality of divided pieces. When the hitch plate 33 is divided, the number of through holes 38 through which the shirtle rod 36 passes is changed by changing the number of divided pieces to be combined. Can be changed. Therefore, for example, even when the number of driving ropes (the shackle rods 36) varies depending on the specifications of the elevator, the number of driving ropes can be increased or decreased by selecting the number of divided pieces to be combined.

[0056] FIG. 9 discloses a sixth embodiment of the present invention.

In the sixth embodiment, the support member 51 is installed on the upper surface of the support beam 7 constituting the gantry 8 shown in FIG. The support member 51 is fixed to the upper surface of the support beam 7 by means of, for example, welding or fastening using a bolt, and maintains a horizontal posture.

A hitch plate 52 is disposed on the support member 51. Each of the support member 51 and the hitch plate 52 has a flat plate shape having four corners. An inertia material 53 is interposed between the support member 51 and the hitch plate 52. The inertia material 53 is an example of a vibration isolator, and is formed of an elastic polymer material such as natural rubber, synthetic rubber, or urethane. The inertia material 53 is a flat plate having a certain thickness. The inertia material 53 has an area that is the same as or slightly smaller than the area of the upper surface of the hitch plate 52 when viewed in plan.

[0058] The support member 51, the coasting member 53, and the hitch plate 52 have a plurality of through holes 54, 55, 56 through which shirt rope rods (not shown) of drive ropes pass, respectively. The shirt rod is inserted into the through holes 54, 55, 56 from below the support beam 7. The upper part of the shirtle rod protrudes upward from the upper surface of the hitch plate 52 and is connected to the hitch plate 52 via a coil spring, a nut and a lock nut, as in the first embodiment.

According to the sixth embodiment, vibration applied to the drive rope during the operation of the elevator is absorbed by the inertia material 53 interposed between the hitch plate 52 and the support member 51. The Therefore, the vibration that tries to propagate the driving rope force to the support member 51 via the hitch plate 52 is surely blocked by the inertia material 53.

Therefore, it is difficult for vibration from the driving rope to propagate to the support beam 7 that supports the support member 51 and the guide rail that supports the support beam 7. As a result, the noise of the elevator can be suppressed accurately.

[0061] According to the sixth embodiment, the inertia material 53 only needs to have the same size as the upper surface of the hitch plate 52 when viewed in plan. Therefore, hitch the outer periphery of the coastal material 53. It is not necessary to protrude outward from the outer periphery of rate 52. Therefore, the inertia material 53 does not interfere with the equipment and parts arranged around the hitch plate 52.

[0062] The free material 53 has the same area as the upper surface of the hitch plate 52.

Therefore, a sufficient contact area between the coasting material 53 and the hitch plate 52 can be secured, and the thickness of the coasting material 53 can be reduced accordingly. Therefore, the coasting material 53 can be formed thin and compact, and an increase in the space along the height direction of the hoistway 1 can be suppressed.

[0063] The inertia material 53 has a plurality of through holes 55, through which the shirt rods of the drive ropes pass. For this reason, the inertia material 53 does not move due to the vibration of the driving rope and does not fall off the support member 51. Therefore, the elastic body 53 is always held at an appropriate position between the support member 51 and the hitch plate 52.

In practicing the present invention, a plurality of inertia materials stacked on each other may be interposed between the hitch plate and the support member. According to this configuration, since the spring constant of each inertial material can be lowered, the natural frequency of the vibration isolation system is lowered. Therefore, the vibration of the driving rope that tries to propagate the hitch plate force to the support member can be reliably blocked.

In the present invention, the vibration isolator is not limited to being composed of a coasting material made of a polymer material such as natural rubber, synthetic rubber, or urethane. For example, a spring element such as an air spring unit or a damping element such as a damping steel plate can be used as a vibration isolator. Even when a spring element or damping element is used as a vibration isolator, it is desirable that the planar area of the vibration isolator and the planar area of the hitch plate be approximately the same.

[0066] The elevator according to the present invention is not limited to an elevator of a type in which a passenger car and a counterweight are suspended in a hoistway via a driving rope. For example, an elevator of a type in which only a car is suspended in a hoistway with a driving rope can be similarly applied.
