Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an elevator counterweight device that reduces the influence of a passing vehicle on a car.
[0002]
[Prior art]
In the elevator, a hoist (not shown) is installed above the hoistway 51 as shown in FIG. 9, and a main rope 53 is hung over a drive sheave 52 connected to an output shaft of the hoist. A car 55 is suspended from one end of the rope 53 via a coil spring 54a, and a counterweight device 56 is also attached to the other end of the rope 53 via a coil spring 54b. The car 55 and the counterweight device 56 are configured to move up and down in directions opposite to each other.
[0003]
The car 55 is provided with a car frame 57 on the outside, and a car room 59 is supported in the car frame 57 via a vibration isolator 58 such as rubber. At the lower part of the car 55, a compensating rope 60 is taken out via a coil spring 54c. The other end of the compensating rope 60 is connected to a lower part of a counterweight device 56 via a compensive 61 installed at a lower part of the hoistway 51. It is moored.
[0004]
FIG. 10 is a front view of the counterweight device suspended from the main rope 53.
[0005]
Guide rails 63 having a substantially T-shaped cross section are vertically and vertically arranged at predetermined intervals by mounting brackets (not shown) in the vertical direction of the surfaces of both hoistway walls 51a facing each other of the hoistway 51. .
[0006]
On the other hand, the counterweight device 56 constitutes a counterweight frame by an upper beam 71, a lower beam 72, and a pair of U-shaped steel vertical frames 73 connected to both ends of both beams 71, 72, and the vertical length of the frame. Loading weights 74 are stacked in the frame U-shaped portion, and two seismic bolts 75, 75 penetrate through holes formed in the loading weights 74, and the upper and lower ends of the bolts are fixed to the upper beam 71 and the lower beam 72. Thus, the loading weight 74 is supported on the counterweight frame.
[0007]
A guide roller 76 is supported on both end sides of the upper beam 71 and the lower beam 72 constituting the counterweight frame via support arms (not shown). Since the guide roller 76 is configured to roll on the opposing surface of the guide rail 63, the counterweight device 56 can move up and down along the guide rail 63. In the figure, reference numeral 77 denotes a hitch plate.
[0008]
In the above-described elevator, the counterweight device 56 moves up and down along the guide rail 63 with the rotation of the drive sheave 52 installed above the hoistway 51. At this time, the counterweight device 56 Moves up and down in the opposite direction to the car 55. For example, when the car 55 moves upward, the counterweight device 56 moves downward while passing the car 55. The reverse is also true.
[0009]
As a result, when the car 55 moves up and down, when the counterweight device 56 and the car 55 pass each other at a short distance, air turbulence is generated between the opposing surfaces of the counterweight device 56 and the car 55, and the car Vibration and noise are generated at 55, which gives the user uncomfortable feeling.
[0010]
In particular, in recent years, with the regeneration of cities, the construction of high-rise buildings and skyscrapers has been increasing, and the speed of raising and lowering the elevator car 55, which is a means of transport in the building, also depends on the height of the building. The speed is getting even faster. This means that as the speed of the car 55 increases, when the counterweight device 56 and the car 55 pass each other, the air turbulence increases more and more between the opposing surfaces, and accordingly the vibration and noise of the car 55 Is getting bigger. It is desired for an elevator user to have an elevator with good ride comfort with less vibration and noise of the car 55 even when the elevator speed is increased.
[0011]
Conventionally, a technique for suppressing air turbulence generated during passing has been proposed. In this prior art, as shown in FIG. 11, a trough-shaped lateral guide deflection device 81 and a side deflection device 82 are attached to a support member 80 erected at the upper and lower ends of the counterweight device 56, and a car 55 The air turbulence generated at the time of passing is deflected in the lateral direction of the counterweight device 56. 83 is a buffer receiver.

Japanese Patent No. 28658894 (FIG. 1)
[0013]
[Problems to be solved by the invention]
However, in the above-described conventional technology, for example, when the counterweight device 56 is lifted, the traveling airflow received by the lateral guide deflection device 81 is caused to flow in four lateral directions. There is a problem that air turbulence is generated by entering the surface passing the counterweight device 56 and the turbulence causes the car to generate vibration and noise.
[0014]
The present invention has been made in view of the above circumstances, and has a counterweight device for an elevator that reduces traveling airflow due to passing of a car and reduces vibration and noise in a car due to air turbulence. The purpose is to provide.
[0015]
[Means for Solving the Problems]
(1) In order to solve the above-mentioned problem, an elevator counterweight device according to the present invention includes a rope suspended from one end of a main rope suspended over a sheave of a hoisting machine. A compensating rope end suspended from the lower end of the car and hanged from the lower part of the car via a compensive is connected, and the car is a counterweight device for an elevator that moves up and down in opposite directions,
At least one or both of the upper and lower parts of the counterweight frame on which the weight is mounted, has a downward slope in the direction opposite to the side of the car side, and the traveling air flow generated when passing the car is said. This is a configuration in which an air deflecting device that deflects along a descending inclined surface is provided.
[0016]
Since the present invention is configured as described above, the air deflecting device that is inclined downward in the direction opposite to the passing surface of the car is provided, so that the traveling air flow at the time of passing is opposite to the passing surface of the car. As a result, most of the traveling airflow generated from the counterweight frame does not enter the opposing surface of the car, and as a result, air turbulence does not easily occur between the opposing surfaces of the car and the counterweight device. Therefore, it is possible to reduce the vibration and noise to the car due to the air turbulence.
[0017]
The air deflecting device has a first plate disposed substantially parallel to a surface on a car side, and the car is inclined downward from a top portion of the first plate in an opposite direction. And the second plate body arranged in such a manner that the traveling air flow generated in the projected cross-sectional area in the moving direction of the counterweight frame is rationally deflected to a surface opposite to the passing surface of the car. It is possible to do.
[0018]
In addition, the second plate body is formed by cutting the second plate body, except for a rope penetrating portion for penetrating a rope and a rope penetrating portion penetrating the rope penetrating portion. When the rope is disposed outside the air deflecting device by providing the penetrating portion closing body mounted on the second plate body so as to close the portion, the rope passes through the rope penetrating portion in the air deflecting device. Air turbulence can be reduced as compared to that of the above, and the rope penetration can be prevented from entering the space of the rope penetration by closing the rope penetration with the obstruction except for the rope penetration. Can be smaller.
[0019]
Furthermore, if the surface position of the through-portion closing body is substantially equal to that of the second plate body, the deflected traveling airflow can smoothly pass over the upper surface of the through-portion closing body, and the air turbulence is not disturbed. It is possible to allow air to flow over the car and the surface in the opposite direction.
[0020]
(2) Further, according to the present invention, if a partition plate is arranged on the side of the counterweight of the counterweight mounted on the counterweight frame so as to cover the weight via a cushioning material, the external wind pressure at the time of passing can be reduced. Even if the partition plate is deformed by acting on it, it is possible to absorb and attenuate the wind pressure collision sound and the sound accompanying the deformation beforehand.
[0021]
(3) In addition, the present invention provides a traveling system in which one or both of the first plate body, the second plate body, and the partition plate are attached to a vibration damping material or a general structural material surface with a vibration damping material sheet. Even if a steep wind pressure external force acts when the air flow is deflected, the vibration can be suppressed, and the noise accompanying the vibration can be reduced.
[0022]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0023]
(First Embodiment)
FIG. 1 is a configuration diagram showing an embodiment of an elevator counterweight device according to the present invention. 1A is a front view, FIG. 1B is a plan view, and FIG. 1C is a cross-sectional view taken along line AA of FIG. 1A.
[0024]
This counterweight device has an upper beam 1 and a lower beam 2 which are arranged substantially parallel to each other at a required distance, and is connected to both ends of both beams 1 and 2, and their opposing sides are formed in, for example, a U-shape. A counterweight frame is formed by the vertical frame 3, and a loading weight 4 is stacked in the frame, and through holes are formed in the loading weight 4, for example, two weight support members 5, 5 such as two seismic bolts and a penetrating member. Through the upper beam 1 and the lower beam 2 to support the load weight 4.
[0025]
Guide rollers 6 are attached via support arms near the upper and lower ends of the counterweight frame, for example, both ends of the upper beam 1 and the lower beam 2, and roll on the opposing surfaces of the guide rails 7 as in the prior art. The counterweight frame is configured to move up and down along the guide rail 7. Further, a main rope 8 is wrapped around a drive sheave (not shown) connected to an output shaft of a hoist installed on the hoistway, and a car (not shown) is provided at one end of the rope 8. Is suspended, and the other end of the rope 8 is fixed through a coil spring 10 to a hitch plate 9 inserted through the upper beam 1 and attached to the lower surface of the upper beam 1. A compensating rope 11 is led out of the lower beam 2 via 10 and is connected to the bottom of the car via a compensive (not shown).
[0026]
Further, an air deflecting device 15 (15a, 15b) for deflecting air to a surface opposite to a passing surface of the car is attached to an upper portion of the upper beam 1 and a lower portion of the lower beam 2 constituting the counterweight frame. I have. Since the air deflector 15a above the upper beam 1 and the air deflector 15b below the lower beam 2 have the same configuration, the air deflector 15a attached to the upper beam 1 will be described below. 2 The air deflecting device 15b at the bottom is omitted.
[0027]
As shown in FIG. 2, the air deflecting device 15a includes a first plate 16 arranged substantially in parallel with a surface on the car side, and a top of the plate 16 on a side opposite to a passing surface of the car. The first plate body 16 and the second plate body 17 are formed at an apex connection angle at an acute angle, and the upper plate 1 is connected to the upper plate 1 or the upper plate 1 at an angle. It is fixed to the counterweight frame.
[0028]
With such a configuration, the air deflecting devices 15a and 15b which are inclined downward in the direction opposite to the passing surface of the car are provided, so that the traveling airflow at the time of passing is in the direction opposite to the passing surface of the car. Rationally, and is deflected along the descending inclined surface, so that most of the traveling airflow generated from the counterweight frame does not enter the opposing surface of the riding weight frame, and the riding weight and the balancing weight frame The air turbulence is less likely to occur between the opposing surfaces. As a result, the air turbulence generated between the facing surface of the car and the counterweight frame is reduced, and accordingly, the vibration and noise applied to the car can be significantly reduced.
[0029]
Further, the air deflection device 15a will be described in detail.
[0030]
The first plate 16 and the second plate 17 are desirably made of a vibration damping material, and the second plate 17 has a rectangular, square, elliptical or the like for passing the main rope 8 through. A rope penetrating portion 18 having a shape is formed, and a penetrating portion closing member 20 is attached to an upper portion of the second plate body 17 to close the rope penetrating portion 18 except for a portion where the rope 8 passes.
[0031]
As shown in FIG. 3, the penetrating portion closing body 20 includes a pair of closing members 20a, 20a having a function of sandwiching the main rope 8 from opposite directions. For example, a semicircular rope insertion hole 21 for allowing two main ropes 8 to pass therethrough is formed, and fixing bolt holes 22 are formed at both ends of each closing member 20a, 20a. After the long bolts 23 are inserted through the fixing bolt holes 22 of the 20a and 20a and tightened with the fixing nuts 24 from the opposite side, the pair of divided closing members 20a and 20a are integrally connected, and then the rope is connected. The penetrating portion 18 is fixed to the second plate 17 so as to close it. If a member that absorbs external force such as a wooden piece, rubber, resin, sponge, or the like is used for the closing members 20a, 20a, even if external force is applied by the vibration of the main rope 8, rubbing noise due to rope vibration is generated. It is possible to make it smaller.
[0032]
Therefore, the rope penetrating part 18 is formed in the second plate 17 which is inclined downward in the direction opposite to the car side, and the main rope 8 is passed through, so that the connection part of the main rope 8 is located inside the air deflecting device 15a. And the air turbulence can be reduced as compared with the case where it is provided outside the air deflection device 15a. Further, by closing the rope penetrating portion 18 with the penetrating portion closing member 20, it is possible to prevent the traveling air flow from entering the space of the rope penetrating portion 18, similarly suppress air turbulence, and reduce vibration. To contribute.
[0033]
It is desirable that the first plate 16 and the second plate 17 are made of a vibration damping material. As the vibration damping material, for example, two or more kinds of metals are melted and mixed, and a high damping material is used. Vibration damping alloys such as a composite type, a ferromagnetic type, a transition type, a twin type, and a crystal grain boundary corrosion type having a vibration absorbing property are exemplified. Further, as a vibration damping material, two or more kinds of polymers are mixed, and a polymer alloy having improved impact resistance and weather resistance, or a resin damping resin having a vibration damping property given to a polymer blend or Wood-based vibration damping material obtained by mixing wood flour or wood chips with a resin as a vibration damping agent and thermoforming, or a thermoplastic resin sheet, thermosetting resin sheet, etc. for intermediate materials such as steel plate, gypsum board, and plywood A composite sandwich vibration damping material having a vibration damping layer is used.
[0034]
If these plates 16 and 17 are made of a vibration damping material, these plates 16 and 17 have an attenuating effect, so that when the traveling air flow is deflected, steep air flow vibrations and wind pressure external forces act. Vibration can be suppressed, and noise accompanying vibration can be reduced.
[0035]
Therefore, according to the above-described embodiment, air turbulence occurs due to passing of the counterweight device and the car, but the first plate member 16 and the second plate member constituting the air deflecting devices 15a and 15b are formed. Since the body 17 is set at an acute angle, and the second plate 17 is inclined downward in the direction opposite to the passing surface of the car, the traveling air flow follows the inclination of the second plate 17. Therefore, the amount of air entrained between the opposing surfaces of the cars is reduced, so that air turbulence is less likely to occur, and the vibration and noise of the cars due to passing each other can be sufficiently reduced.
[0036]
The air deflecting device 15 is provided on the upper and lower portions of the frame, but may be provided on only one of them. Since the configuration and operation of the air deflecting device 15b are the same, only the air deflecting device 15a will be described.
[0037]
(Second embodiment)
FIG. 4 is a configuration diagram showing another embodiment of the elevator counterweight device according to the present invention.
[0038]
This embodiment is another example of the configuration of the air deflectors 15a and 15b provided on the upper and lower portions of the frame. Since the air deflectors 15a and 15b have the same configuration, the air deflector 15a will be similarly described below. explain.
[0039]
In the air deflector 15a, the first plate 16 and the second plate 17 are made of a general structural material such as a general steel plate which is inexpensive, and the front or both sides of these plates 16, 17 are provided. This is a configuration in which pasting type vibration damping material sheets 16a and 17a are pasted on the sheet.
[0040]
As a vibration damping material to be the pasting-type damping material sheets 16a and 17a, for example, a single layer in which a plastic-based, rubber-based, or asphalt-based sheet-shaped vibration damping material is adhered to the main material with an adhesive or an adhesive material. A sticking type vibration damping material is used, or a two-layer sticking type vibration damping material in which a restraining plate such as a thin steel plate and a rubber damping material are stuck with an adhesive or an adhesive is used.
[0041]
Therefore, according to the above-described embodiment, by using the plates 16 and 17 in which the adhesive damping material sheets 16a and 17a are attached to the general structural material, the same as the first embodiment described above. In addition to the effect of the first embodiment, it is possible to reduce the cost by partially attaching without using an expensive vibration damping material as in the first embodiment, and to reduce the air generated when the traveling air flow is deflected. Flow vibration and external force of wind pressure can be easily absorbed and attenuated, and noise accompanying vibration can be reduced.
[0042]
(Third embodiment)
FIG. 5 is a configuration diagram showing another embodiment of the elevator counterweight device according to the present invention.
[0043]
This embodiment is another example of the structure of the air deflecting devices 15a and 15b provided on the upper and lower portions of the counterweight frame. Since the air deflecting devices 15a and 15b have the same structure, the air deflecting device will be described below. The device 15a will be described.
[0044]
In the air deflecting device 15a according to the first embodiment, the penetrating portion closing body 20 is attached to the upper surface of the second plate member 17 in order to close the rope penetrating portion 18 formed in the second plate member 17. In the present embodiment, with respect to the rope penetration portion 18 formed in the second plate 17, the cutout shape of the rope penetration portion 18 from the back side of the second plate 17 is substantially equal to the notch shape, and The closing members 20b, 20b each having a convex step portion corresponding to the thickness of the plate member 17 are fitted, and appropriate portions of the closing members 20b, 20b are fixed to the second plate member 17 by the anchor bolts and the fixing nuts 24. Configuration. Therefore, the surface portions of the respective convex steps of the closing members 20b, 20b are set at surface positions substantially equal to the surface of the second plate body 17.
[0045]
Therefore, according to such an embodiment, the surface of the through-portion closing body 20 and the surface of the second plate 17 are substantially flush with each other. Turbulence can be prevented, and vibration and noise due to air turbulence can be avoided.
[0046]
(Fourth embodiment)
FIG. 6 is a configuration diagram showing another embodiment of an elevator counterweight device according to the present invention.
[0047]
In this embodiment, the mounting angle and the curved surface of the second plate 17 connected to the top of the first plate 16 are formed, and the angle between the first plate 16 and the second plate 17 is adjusted. It is configured to be more acute. Other configurations are the same as those of the first embodiment.
[0048]
That is, the second plate 17 is inclined downward from the top of the first plate 16 toward the direction opposite to the passing surface of the car so as to be a little more acute angle than in the first embodiment. A first plate piece 17a extending to the trunk of the rope penetration portion 18, and a concave curved second surface connected to the lower end of the plate piece 17a and forming a mid-abdomen of the rope penetration portion 18. Plate piece 17b, a flat third plate piece 17c connected to the end of the second plate piece 17b, and another end connected to the end of the third plate piece 17c, for example. A fourth curved piece 17 d connected to the beam 1. The second plate body 17 includes the first plate piece 17a to the fourth plate piece 17d, but may have a configuration without the fourth plate piece 17d.
[0049]
Therefore, the use of the second plate 17 having the above-described configuration provides the following operation. When the second plate 17 is formed of two or more surfaces having different angles, the angle between the first plate 16 and the second plate 17 can be further sharpened, and the air deflecting device can be formed. The installation height of 15a, 15b can be reduced. This means that the heights of the air deflectors 15a and 15b can be arbitrarily changed according to the spaces at the upper end and the lower end of the hoistway 1, and a rational design taking the hoistway dimensions into consideration can be performed.
[0050]
Further, by connecting the curved plate 17b between the first plate 17a and the third side 17c having different mounting angles, the air turbulence can be further reduced, and the vibration and the air turbulence caused by the air turbulence can be further reduced. Noise can be reduced.
[0051]
(Fifth embodiment)
FIG. 7 is a block diagram showing another embodiment of the elevator counterweight device according to the present invention, in which the counterweight described in FIG. FIG.
[0052]
This embodiment is an example in which a frame of a counterweight which is hardly subjected to external wind pressure and vibration due to passing each other is configured.
[0053]
The loading weights 4 are stacked in the frame, and a plurality of partitioning plates 31 are attached to cover some unevenness on the surface of the loading weights 4. The corners of the partitioning plates 31 are attached to the counterweight frame. It is fixed by a fixing bolt 33 via an elastic body 32. As the elastic body 32, a rubber elastic body using a main material such as natural rubber, butyl rubber, or neoprene rubber is used. Further, a cushioning material 34 is provided between the partition plate 31 and the loading weight 4. This cushioning material 34 is stuck or interposed on the back surface of the partition plate 31.
[0054]
The material constituting the partition plate 31 is a vibration damping material. As the vibration damping material, for example, a composite type, a ferromagnetic type, a transition type, a twin type, a sintered type, or a grain boundary corrosion obtained by dissolving and mixing two or more kinds of metals and imparting a high vibration absorbing property thereto. In addition to damping alloys such as molds, two or more types of polymers are mixed to improve the impact resistance and weather resistance of polymer alloys or polymer blends. Alternatively, a wood-based vibration damping plate obtained by mixing wood flour or wood chips with a resin as a vibration damping agent and thermoforming the mixture may be used.
[0055]
Further, as the cushioning material 34, for example, a foaming type sponge, a vibration damping foaming type cushioning material mainly composed of styrene / butadiene rubber is used.
[0056]
Next, the operation of the above configuration will be described.
[0057]
The cushioning member 34 is provided between the partition plate 31 located on the passing surface of the car and the loading weight 4 and the partition plate 31 is made of a vibration damping material. Therefore, even if an external force of wind pressure at the time of passing acts on the partition plate 31 to cause deformation or vibration, a noise due to the wind contact sound or deformation is absorbed, thereby reducing noise from the partition plate 31. In addition, since the cushioning member 34 is provided inside, even when a deformation factor due to an external wind pressure is generated, the shock is not transmitted to the load weight 4 and the vibration can be reduced.
[0058]
Further, in the above embodiment, the partition plate 31 is made of a vibration damping material. However, as shown in FIG. 8, for example, the partition plate 31 is made of a general structural material such as a general steel plate which is inexpensive, A configuration in which an adhesive-type damping material sheet 31a is attached to the front side or both sides of 31 may be used. In addition, as a vibration damping material which becomes a pasting type vibration damping sheet, for example, a single-layer pasting type vibration damping material in which a plastic-based, rubber-based, or asphalt-based sheet-shaped vibration damping material is adhered to the main material with an adhesive or an adhesive is used. For example, a vibration-damping material is used, or a two-layer-attached-type damping material in which a rubber-based damping material is adhered to an adhesive or an adhesive on a restraining plate such as a thin steel plate is used. In this case, a similar effect can be obtained.
[0059]
The present invention is not limited to the above-described embodiment, and can be implemented with various modifications without departing from the scope of the invention.
[0060]
Further, the embodiments can be implemented in combination as much as possible, and in that case, the effect of the combination can be obtained. Furthermore, each of the above embodiments includes various upper and lower stage inventions, and various inventions can be extracted by appropriately combining a plurality of disclosed components. For example, when an invention is extracted because some constituent elements can be omitted from all the constituent elements described in the means for solving the problem, if the extracted invention is implemented, the omitted part is omitted. Is appropriately supplemented by well-known conventional techniques.
