Description

  An elevator that carries at least one of a person and luggage.

  In an elevator, a cab carrying at least one of a person and luggage moves up and down the hoistway. When the speed of raising and lowering the cab increases, noise is generated due to the turbulence of the airflow, and the noise may impair comfort in the cab. In order to maintain comfort in a car room, a technology has been proposed in which air conditioners are arranged above and below the car room to suppress turbulence in airflow and thereby reduce noise in the car room (for example, Patent Document 1).

JP 2003-118954 A

  Patent Literature 1 proposes a technique in which an air conditioner having an arc shape is connected to the upper and lower surfaces of a rectangular parallelepiped cab to suppress the entrainment of airflow by the end of the rectangular cab.

  However, the connected conventional air conditioner has a complicated shape, and costs including processing costs and installation costs are high. Therefore, the cost of the elevator itself may increase. Further, when the air conditioner is arranged so as to be connected to the upper and lower surfaces of the car room, the ceiling surface and the floor surface are covered with the air conditioner. For this reason, when the maintenance worker performs maintenance on the elevator, it is difficult for the maintenance worker to go out of the inside of the cab to the upper and lower sides of the cab, and the maintainability may be deteriorated.

  The present invention has been made in view of the above-described circumstances, and provides an elevator that can suppress the increase in cost and the deterioration in maintainability while suppressing the inhibition of the comfort of a car due to noise. With the goal.

The elevator according to the present invention includes a cab that moves up and down and a ventilation resistance member. Ventilation resistance member, at least one side of the lifting direction of the cab cover through the clearance space, and a vent that opens to a different elevation direction to the rope hole and rope holes through the rope for suspending the cage chamber Then, a part of the wind flowing from one side is passed through the gap space.

  ADVANTAGE OF THE INVENTION According to this invention, since a ventilation resistance member is arrange | positioned in the raising / lowering direction of a cab, a sound source can be kept away from the ceiling or floor of a cab, and the disturbance of the comfort of a cab by noise can be suppressed. Since the ventilation resistance member has a ventilation opening opened in the elevating direction, the air resistance is reduced and noise can be reduced. Further, since a ventilation resistance member having a relatively simple shape is used, cost increase can be suppressed. Further, since there is a clearance space between the airflow resistance member and the cab, the maintenance worker can relatively easily go out of the cab to the upper and lower parts of the cab, thereby deteriorating the maintainability. Can be suppressed.

  Hereinafter, an embodiment of an elevator disclosed in the present application will be described in detail with reference to the accompanying drawings. The embodiments described below are merely examples, and the present invention is not limited by these embodiments.

Embodiment 1 FIG.
FIG. 1 is a perspective view showing a part of the elevator according to the first embodiment. Around the cab 1 that moves up and down in the hoistway, there is a frame-shaped car frame 2 that supports the cab 1. A rope 3 for suspending the car room 1 is fixed to the car frame 2, and the hoist is used to move the car room 1 up and down in the elevating direction. In the first embodiment, a streamlined ventilation resistance member 4 is arranged on at least one of the upper and lower sides in the vertical direction of the car 1 for the purpose of reducing the car interior noise. The ventilation resistance member 4 is a member that exhibits resistance to ventilation through this member when the elevator moves up and down.

  FIG. 2 shows an example of the ventilation resistance member 4. 3 is a cross-sectional view of the elevator taken along the line XX shown in FIG. 1, and FIG. 4 is a cross-sectional view of a part of the elevator taken along the line YY shown in FIG. The ventilation resistance member 4 is formed of four plates 4a to 4d, and the inside of the ventilation resistance member 4 is hollow. The upstream surface 4a is an arc-shaped curved surface protruding upward in the elevating direction in order to obtain a rectifying effect, and the other surfaces are flat plates. At the end of the ventilation resistance member 4 on the side of the door 6 that can be opened and closed, a cut 7 protruding upward in the vertical direction is provided.

  The case where the ventilation resistance member 4 is installed above the elevator will be described, but it may be installed below the elevator. The ventilation resistance member 4 installed on the lower side may be configured to be upside down with the ventilation resistance member 4 installed on the upper side. In other words, the airflow resistance member 4 installed on the lower side may be configured to have the eaves 7 projecting downward.

  The hiss 7 is for reducing the amount of inflow to the door 6 having a low sound insulation performance, and the length of the hiss 7 is desirably 30 mm or more. The hessian 7 is arranged at a position flush with the end face of the door sill 14. In other words, they are arranged so that the distance from the wall of the hoistway on the side of the door 6 is the same between the hessian 7 and the end face of the threshold 14.

  The ventilation resistance member 4 is separated from the upper surface of the cab 1, and a clearance space is formed between the ventilation resistance member 4 and the upper surface of the cab 1. The ventilation resistance member 4 has a rope hole 8 provided so as not to interfere when the rope 3 is fixed to the car frame 2, and a ventilation hole 9 for flowing air from the upstream side to the downstream side of the ventilation resistance member 4. Is provided. The ventilation opening 9 is open in the elevating direction. The flow rate passing through the ventilation opening 9 has a ventilation resistance of less than 50% with respect to the upstream side. The ventilation opening 9 is a small hole having a small size. The ventilation opening 9 narrows and takes in a part of the wind from the upstream and flows it into the gap space on the car room 1 side. For this reason, resistance occurs to the airflow flowing into the cab 1 via the airflow resistance member 4.

  The outer shape of the ventilation resistance member 4 has substantially the same shape as the shape of the ceiling of the car room 1 projected in the elevating direction. As shown in FIG. 1, when the ceiling is rectangular, the ventilation resistance member 4 is also rectangular. The outer shape of the ventilation resistance member 4 is desirably the same size as the ceiling, but may be slightly smaller (for example, the length of one side is about 10%) and substantially the same shape. Note that when the ceiling is rectangular, a rectangle with rounded corners and a case where a part of the outer shape has a depression or the like are considered to be the same shape.

  When the ceiling of the car room 1 is flat, the downstream surface of the ventilation resistance member 4 is substantially parallel to the ceiling.

  FIG. 5 is a perspective view illustrating an example of a ventilation resistance member included in the elevator according to the first embodiment. The shape of the ventilation holes 9 may be circular as shown in FIG. 2 or may be slit-like as shown in FIG. 5, and a plurality of ventilation holes 9 having a small area are arranged. The ventilation port 9 is a thin slit that narrows down and takes in a part of the wind from the upstream and flows it into the gap space on the car room 1 side. For this reason, resistance occurs to the airflow flowing into the cab 1 via the airflow resistance member 4.

  FIG. 1 shows an example in which the airflow resistance member 4 is arranged in the car frame 2. However, if the airflow resistance member 4 is above the upper surface of the car room 1 or below the lower surface, it does not need to directly contact the car frame 2. good.

  The area of the ventilation resistance member 4 in the horizontal direction is substantially equal to the size of the ceiling, which is the upper surface, and the floor, which is the lower surface, of the cab 1. The material of the ventilation resistance member 4 is an aluminum plate, a steel plate, a damping steel plate obtained by laminating two steel plates with a viscoelastic resin, or the like.

  FIG. 6 is a cross-sectional view illustrating an example of the ventilation resistance member included in the elevator according to the first embodiment. FIG. 2 is a cross-sectional view when the ventilation resistance member is cut along a cross section similar to the XX cross section illustrated in FIG. 1. In FIG. 1, the ventilation holes 9 are provided on the upstream surface 4 a of the ventilation resistance member 4. However, as shown in FIG. The configuration may be such that the air that has flowed into the airflow is made to flow downstream from the air vent 9. Further, in this embodiment, the ventilation resistance member 4 has a semicircular shape, but may have a triangular shape or a trapezoidal shape for obtaining a rectifying effect, and is not limited to the external shape shown in FIG. Further, when the ventilation surface 9 is provided on the upstream surface 4a of the ventilation resistance member 4, it is also possible to configure only the upstream surface 4a.

  The relationship between the flow around the car room 1 and the effect on the noise in the car 1 of the elevator according to the first embodiment will be described with reference to FIGS.

  FIG. 7 shows the flow around the cab 1 when there is no ventilation resistance member 4. When ascending, the air upstream of the cab 1 flows all around the ceiling so as to be pushed out by the ceiling, passes through the edge 10 of the ceiling, and flows to the side of the cab 1. At this time, since a large wind pressure is applied to the ceiling, the ceiling is vibrated by the fluctuation of the wind pressure and propagates into the car 1 as vibration noise. In addition, since the vortex 12 becomes a noise source near the side surface of the cab 1 due to the separation at the edge 10 of the ceiling, the noise propagates into the cab 1 through the walls and doors of the cab 1.

  FIG. 8 shows the flow around the cab 1 when the ventilation resistance member 4 having no ventilation opening 9 is arranged. When there is the ventilation resistance member 4, the air on the upstream side of the cab 1 is pushed out by the ventilation resistance member 4 instead of the ceiling. Thereafter, the air flows through the edge 11 of the ventilation resistance member 4 and flows to the side surface of the cab 1. The wind speed of the air passing through the edge 11 of the ventilation resistance member 4 is defined as U1. The vibration generated at the ceiling and the noise generated at the edge, which occurs when the ventilation resistance member 4 is not provided, moves from the vicinity of the ceiling to the vicinity of the ventilation resistance member 4. When the distance between the sound source and a sound-insulating wall such as a ceiling or a wall is short, the sound-insulating performance is greatly reduced. Therefore, the sound-insulating performance can be suppressed by separating the sound source from the cab 1 by the ventilation resistance member 4, The noise in the car room 1 can be reduced. Further, since the upstream surface 4a of the ventilation resistance member 4 has a streamlined shape, a rapid change in speed can be suppressed, and noise can be reduced.

  FIG. 9 shows the flow around the cab 1 when the ventilation resistance member 4 having the ventilation opening 9 is arranged. The presence of the ventilation port 9 allows a part of the air on the upstream side of the car room 1 to pass through the ventilation port 9. The velocity of the air passing through the edge 11 of the ventilation resistance member 4 is U2, and the velocity of the air passing through the ventilation opening 9 is U3.

  The air that has passed through the ventilation opening 9 has a low flow velocity due to airflow resistance, and flows near the ceiling. Since the flow reaching the ceiling has a low flow velocity, the pressure fluctuation near the ceiling is reduced, and as a result, the vibration of the ceiling is reduced. That is, in this case, the relationship of U1> U2> U3 holds.

  By flowing air to the ceiling side through the ventilation opening 9, the bias of the wind speed distribution near the edge 11 is reduced, and noise generated at the edge can be reduced. As a result, the noise in the cab 1 can be reduced. When the material of the ventilation resistance member 4 is a damping steel plate, the vibration can be reduced as compared with the case of using an aluminum plate or a steel plate. Therefore, radiation noise generated from the ventilation resistance member 4 can be reduced, and noise can be further reduced.

  The relationship between the flow around the car room 1 and the influence on the noise has been described above by taking the elevator as an example. At the time of descending, the same phenomenon and effect can be obtained simply by changing the ceiling to the floor, and the description is omitted.

Embodiment 2 FIG.
FIG. 10 is a schematic sectional view showing an elevator according to the second embodiment. In the second embodiment, a cab 1 that moves up and down in the hoistway of the first embodiment, a car frame 2 that supports the cab 1, a rope 3 for moving the cab 1 and the car frame 2 up and down, and a hoist In addition, an L-shaped ventilation resistance member 4 having ventilation holes 9 arranged on at least one of the upper and lower sides of the cab 1 is added. More specifically, a ventilation resistance member 4 including a flat plate portion provided with a plurality of ventilation holes 9 and a plate-shaped eave 7 extending perpendicularly to the flat plate portion is added.

  FIG. 11 shows an example of the ventilation resistance member 4. FIG. 12 is a sectional view of the elevator cut along the ZZ section shown in FIG. The ventilation resistance member 4 has an L-shape, and an end portion of the ventilation resistance member 4 on the side of the door 6 that can be opened and closed is provided with an eave 7 that projects upward in the vertical direction. The arrangement and material of the ventilation resistance member 4 are the same as those in the first embodiment.

  The provision of the L-shaped ventilation resistance member 4 having the ventilation holes 9 arranged on at least one of the upper and lower sides of the cab 1 makes it possible to reduce cab noise. Further, since the ventilation resistance member 4 has a simple shape, it can be configured at a low cost.

Embodiment 3 FIG.
FIG. 13 is a schematic sectional view showing an elevator according to the third embodiment. In the third embodiment, a cab 1 that moves up and down in the hoistway of the second embodiment, a car frame 2 that supports the cab 1, a rope 3 for moving the cab 1 and the car frame 2 up and down, and a hoist In addition to the ventilation resistance member 4 having the ventilation holes 9 arranged on one of the upper and lower sides of the car room 1, a ventilation resistance member 4 arranged on the other upper and lower sides of the car room 1 is added as shown in FIG.

  By providing the ventilation resistance members 4 on the upper and lower sides of the cab 1, it is possible to reduce the cab noise not only when the cab 1 rises but also when it falls.

Embodiment 4 FIG.
FIG. 14 is a perspective view showing a part of the elevator according to the fourth embodiment. FIG. 15 is a perspective view illustrating an example of a ventilation resistance member included in the elevator according to the fourth embodiment. In the fourth embodiment, a cab 1 that moves up and down in the hoistway of the second embodiment, a car frame 2 that supports the cab 1, a rope 3 for moving the cab 1 and the car frame 2 up and down, and a hoist As shown in FIGS. 9 and 10, in addition to the ventilation resistance member 4 having the ventilation holes 9 arranged on one of the upper and lower sides of the cab 1, the surface of the ventilation resistance member 4 on the opposite side to the cab 1, On the upper surface of the resistance member 4, a permeable member 5 having air permeability is arranged. In order to provide air permeability, the air permeable member 5 has a fine air passage, and is supported by the air flow resistance member 4. As in the first to third embodiments described above, the ventilation resistance member 4 with the ventilation member 5 is held in the cab 1 at an interval. The ventilation resistance member 4 according to the fourth embodiment has a ventilation hole 9 of a large size and lower ventilation resistance than the ventilation resistance members 4 of the first to third embodiments. However, for convenience of explanation to clarify the differences between the first to fourth embodiments, the component 4 according to the fourth embodiment is also referred to as a ventilation resistance member and will be described below.

  The shape of the ventilation opening 9 of the ventilation resistance member 4 is different from the shape described in the second embodiment, and the ventilation opening 9 has a large area. In the second embodiment, since the ventilation member 5 is not provided, the area of the ventilation opening 9 is reduced. However, in the fourth embodiment, the ventilation member 5 capable of controlling the amount of air passing through the ventilation opening 9 is provided. The degree of freedom of the shape of the mouth 9 increases. In the fourth embodiment, the provision of the large ventilation holes 9 makes it possible to reduce the processing cost and reduce the weight. The installation area of the permeable member 5 is the same as that of the permeable resistance member 4, and the thickness of the permeable member 5 is preferably 1 mm or more.

  Although the permeable member 5 is made of a material having air permeability, it should be made of a soft material in which the thickness of the permeable member 5 changes by wind pressure so as to obtain an effect of reducing pressure fluctuation due to wind pressure. Is desirable. As an example, materials such as nonwoven fabric, rock wool, and urethane can be employed. These materials have a fine ventilation path inside, and generate resistance when the wind passes. Therefore, the ventilation resistance member 4 with the ventilation member 5 has ventilation resistance.

  The air permeable member 5 is bonded by a double-sided tape or the like, a pin is inserted into the air permeable member 5, a method of covering the air permeable member 5 with a band or the like, and a method of fixing with a fastening member such as a rivet or a bolt. It can be fixed to the ventilation resistance member 4 by using.

  By combining the ventilation resistance member 4 having the ventilation opening 9 and the ventilation member 5 made of a ventilation material, the air on the upstream side of the car room 1 hits the ventilation resistance member 4 and the ventilation member 5, Some air passes through the ventilation resistance member 4 and the ventilation member 5. At this time, since the gas passes through the complicated flow path in the air permeable member 5, the flow velocity is reduced and the flow is rectified and flows to the vicinity of the ceiling. Since the rectification effect is added to the effect of the second embodiment, it is possible to further reduce noise than in the second embodiment. In addition, by providing the permeable member 5 also near the edge of the ventilation resistance member 4, the speed is reduced and rectified when passing through the inside of the permeable member 5, so that noise generated near the edge can be reduced. Room noise can be further reduced.

  The upstream side of the ventilation resistance member becomes a stagnation point of the airflow, and may be a place where the pressure fluctuation is the largest. Since the air permeable member 5 is provided on the surface of the air flow resistance member 4 on the side opposite to the car room 1, the effect of absorbing pressure fluctuations is relatively large, and the risk of the air permeable member 5 being detached by wind pressure is reduced. In the above, the description has been made in comparison with the second embodiment using the ventilation resistance member 4 having the same shape. However, the ventilation member 5 can be used in the first embodiment.

Embodiment 5 FIG.
FIG. 16 is a cross-sectional view of a ventilation resistance member and a ventilation member included in the elevator according to the fifth embodiment. FIG. 17 is a schematic diagram showing the flow downstream of the ventilation resistance member when there is no ventilation member. FIG. 18 is a schematic diagram illustrating a flow downstream of the ventilation resistance member included in the elevator according to the fifth embodiment. The components of the elevator according to the fifth embodiment are the same as those of the fourth embodiment, but the arrangement of the permeable member 5 is different.

  As shown in FIG. 16, the airflow resistance member 4 is arranged so as to surround the entire circumference of the airflow resistance member 4 with the airflow resistance member 5. In the case where the combination of the ventilation resistance member 4 and the ventilation member 5 is a rectifying device, the edge radius of the rectification device is not the radius of the edge 11 of the ventilation resistance member 4 but the bending of the ventilation member 5 in this manner. Radius. That is, the edge radius of the rectifier increases.

  The effect of increasing the edge radius will be described with reference to FIGS. FIG. 17 shows the wake flow when only the ventilation resistance member 4 is provided. By separating at the edge 11 of the ventilation resistance member 4, a vortex 12 which is a noise source is generated in the wake. Since the downstream side of the ventilation resistance member 4 has a negative pressure, the vortex 12 moves inward as it flows downstream, and interferes with the cab 1 downstream of the ventilation resistance member 4. When interference occurs, large pressure fluctuations occur in the vicinity of the ceiling, walls, and door 6 of the cab 1, and the noise inside the cab 1 increases.

  FIG. 18 shows a wake flow when the permeable member 5 is arranged as shown in FIG. By increasing the radius of the edge 11 of the ventilation resistance member 4 with the ventilation member 5, the negative pressure area downstream of the ventilation resistance member 4 is reduced, and the vortex 12 moves inward behind the ventilation resistance member 4. It has the effect of reducing. Therefore, it does not interfere with the cab 1 downstream of the ventilation resistance member 4, and the noise can be further reduced as compared with the second embodiment.

  In the fifth embodiment, the area of the ventilation resistance member 4 in the horizontal direction is increased by the thickness of the air permeable member 5, and may be larger than the area of the ceiling or floor of the cab 1. In that case, the area of the ventilation resistance member 4 is reduced by the thickness of the ventilation member 5. It is desirable that the thickness of the permeable member 5 be 10 mm or more (R 10 mm or more).

  The relationship between the flow around the car room 1 and the influence on the noise has been described above by taking the elevator as an example. At the time of descending, the same phenomenon and effect can be obtained simply by changing the ceiling to the floor, and the description is omitted.

Embodiment 6 FIG.
FIG. 19 is a perspective view showing a normal shape of a ventilation resistance member included in the elevator according to Embodiment 6. FIG. 20 is a perspective view illustrating a shape of a ventilation resistance member included in the elevator according to Embodiment 6 during operation. In the sixth embodiment, the cab 1 that moves up and down in the hoistway, the car frame 2 that supports the cab 1, the rope 3 and the hoist that raises and lowers the cab 1 and the car frame 2, and the cab 1 In this configuration, the airflow resistance member 4 is disposed on at least one of the upper and lower sides. Embodiment 2 is different from Embodiment 2 in the structure of the ventilation resistance member 4.

  If the distance between the ceiling and the ventilation resistance member 4 is higher than the height of the worker, there is no problem. However, if the distance is shorter than the height of the worker, it is difficult for the worker to perform maintenance work on the ceiling. Embodiment 6 is effective in such a case.

  19 and 20 show shapes of the ventilation resistance member 4 included in the elevator according to the sixth embodiment during normal operation and during work. In the ventilation resistance member 4 according to the sixth embodiment, a plurality of ventilation resistance members 4e, 4f, and 4g are connected by a hinge 13. As a result, the ventilation resistance member 4 can be bent, and work on the ceiling becomes easy.

  19 and 20, the breathable member 5 is not used. However, when the plurality of ventilation resistance members 4e, 4f, and 4g are arranged so as not to interfere with each other when bent by the hinge 13, the combination with the ventilation member 5 is also possible. Although the ventilation resistance members 4e and 4g are bent upward in FIG. 20, the same effect can be obtained by bending downward. Further, in this embodiment, the ventilation resistance member 4 is divided into three parts, but it is also conceivable to integrate the 4f and 4g into a two-part structure.

FIG. 21 is a perspective view showing a ventilation resistance member included in the elevator according to the seventh embodiment. FIG. 22 is a cross-sectional view illustrating a ventilation resistance member included in the elevator according to Embodiment 7. In the seventh embodiment, the cab 1 that moves up and down in the hoistway, the car frame 2 that supports the cab 1, the ropes 3 for raising and lowering the cab 1 and the car frame 2, and a hoist are provided. is there. At least one of the upper and lower sides of the car room 1 is provided with a ventilation resistance member 4j in which two plate members 4h and 4i having ventilation holes are arranged. A gas permeable member 5 is interposed between the two plate members 4h and 4i, and a cut 7 is provided at an end of the upstream plate member 4h.

The two plate members 4h and 4i are arranged in the elevating direction, and the ventilation port 9 of the upstream plate member 4h and the ventilation port 9 of the downstream plate member 4i correspond in the elevating direction, respectively. It is located in. Since the two plate members 4h and 4i and the permeable member 5 are used, the vibration is reduced in the ventilation resistance member 4j, the sound insulation performance of the ventilation resistance member is improved, and the noise in the car interior can be further reduced. .

  The invention is not limited to the specific details and representative embodiments described and described above. Further modifications and effects which can be easily derived by those skilled in the art are also included in the present invention.
