Description

The present invention relates to an elevator device including a car having an airtight structure.

In a long-stroke elevator, an air pressure control device for controlling the air pressure in the car is provided in order to alleviate the discomfort of the ears due to a sudden change in air pressure. The air pressure control device operates the intake blower and the exhaust blower when the car moves up and down in the hoistway to pressurize or depressurize the air pressure in the car to keep the amount of change in air pressure per unit time constant. Keep in.

In such an elevator, the air pressure inside the car is changed to be different from the outside air pressure, so that the airtightness of the car is improved. On the other hand, the technique described in Patent Document 1 is known.

Seal the gap.

International Publication No. 2017/138060

According to the technique described in Patent Document 1, during pressurization and depressurization by the air pressure control device, the flexible member is provided with the flexible member and the sill due to the restoring force of the flexible member itself and the pressure difference between the inside and outside of the car. Three forces are applied: the negative pressure generated by the air flow generated in the gap between the two, and the pressure difference pressure. Of these three forces, the negative pressure and the pressure difference pressure push the flexible member toward the sill side against the restoring force. As a result, the gap between the lower end of the car door and the car sill is sealed. However, there is a problem that chattering occurs in the flexible member until the pressure difference between the inside and outside of the car reaches a predetermined value due to pressurization and depressurization by the atmospheric pressure control device, and abnormal noise is generated.

As described above, when the flexible member is pressed against the sill by the negative pressure and the pressure difference pressure and the flexible member comes into contact with the sill, the gap between the flexible member and the sill disappears, and the negative pressure Will not occur. In this state, if the restoring force is larger than the pressure difference pressure, a gap is generated again. Therefore, a negative pressure is generated again, and the flexible member is pressed against the sill side by the negative pressure and the pressure difference pressure. Since such an operation is repeated until the pressure difference between the inside and outside of the car reaches a predetermined value, chattering occurs in the flexible member and an abnormal noise is generated.

Therefore, the present invention provides an elevator device capable of reducing abnormal noise generated during pressurization and depressurization in the car.

In order to solve the above problems, the elevator device according to the present invention controls the pressure inside the car, and presses or reduces the pressure inside the car at the lower end of the car door provided in the car. Accordingly, it has a flexible member that closes the gap between the car door and the car sill provided in the car, the flexible member is made of an elastic body, and the flexible member is more than a flexible member. A plurality of members having a high mass density are partially arranged , the flexible member has a movable portion parallel to the flat surface portion of the cage sill, and the plurality of members are arranged in the movable portion, and a plurality of members are arranged. The members are arranged intermittently along the longitudinal direction of the flexible member, and the movable portion of the flexible member faces the flat surface portion of the car sill in response to the pressurization or depressurization of the pressure in the car. By shifting downward and contacting the flat surface portion of the car sill, the gap between the car door and the car sill is closed, and the movable part of the flexible member is pressurizing the pressure inside the car. Alternatively, during depressurization, when the restoring force causes an upward displacement from the flat surface portion of the sill to create a gap between the movable portion and the flat surface portion of the cage sill, a plurality of members in the movable portion of the flexible member are arranged. The portion to be formed is displaced downward by its own weight, and the state of being in contact with the flat surface portion of the car sill is maintained .

According to the present invention, it is possible to reduce abnormal noise generated when the air pressure in the car is pressurized and when the pressure is reduced.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each figure, those having the same reference number indicate the same constituent requirements or constituent requirements having similar functions.

FIG. 1 is a side sectional view showing an overall outline of an elevator device according to an embodiment of the present invention.

As shown in FIG. 1, the elevator device 100 includes a car 1 and a counterweight 104 that move up and down in the hoistway 102, a main rope 105 that suspends the car 1 and the counterweight 104 in the hoistway 102, and a main rope 105. It has a hoisting machine (not shown) having a sheave 106 on which the rope 105 is wound, and a warp wheel 107 on which the main rope 105 is wound. In the present embodiment, the hoisting machine (including the sheave 106) and the warp wheel 107 are provided in the machine room 108 arranged in the upper part of the hoistway 102. In the elevator device 100 configured in this way, when the main rope 105 is driven by the rotation of the sheave 106 of the hoisting machine, the car 1 and the balance weight 104 move up and down in the hoistway 102 in opposite directions. do. The main rope 105 is connected to a car frame that supports the car chamber in the car 1, and is also connected to a frame that supports a plurality of weight pieces in the counterweight 104.

FIG. 1 schematically shows the bottom floor 109 and the top floor 110 of the building in which the elevator device 100 is installed, but the number of floors in the building may be arbitrary. Further, a landing door 111 is provided on each floor. When the car 1 is stopped, the landing door 111 is engaged with the car door (“2” in FIG. 2) provided in the car 1 so as to face the car door, and the car door is driven by the door drive device provided in the car 1. Opens and closes with.

FIG. 2 is an external perspective view of the car according to the present embodiment.

In the car 1, a car door 2 for entrance / exit is provided on the front side, and an air pressure control device including an intake blower 3 and an exhaust blower 4 is provided on the upper part. When the car 1 moves up and down in the hoistway, the air pressure control device controls the intake blower 3 and the exhaust blower 4 to pressurize and depressurize the air pressure in the car 1, thereby increasing the air pressure per unit time. The amount of change is kept constant. As a result, the discomfort felt by the passengers in the car 1 is alleviated.

For example, in one traveling stroke in which the car 1 travels from the lowest floor 109 to the top floor 110 in FIG. 1, the car 1 is accelerated from the stopped state on the lowest floor 109 and has a maximum speed (for example, a rated speed). ) Is reached, the vehicle is decelerated and stops at the top floor 110. At this time, if the air pressure inside the car is not controlled, the air pressure inside the car 1 becomes equal to the outside air pressure at the position of the car 1. Therefore, the atmospheric pressure in the car 1 gradually decreases from the atmospheric pressure in the lowermost floor 109 in response to acceleration, the change in atmospheric pressure becomes larger before and after the maximum speed, and gradually in the uppermost floor 110 in response to deceleration. It approaches the atmospheric pressure, that is, the minimum value.

On the other hand, in the present embodiment, the air pressure in the car 1 is depressurized by the pressure control device according to the acceleration, turns to pressurization near the maximum speed, and is pressurized according to the deceleration. As a result, the amount of atmospheric pressure attenuation per unit time is maintained at a predetermined value during one running stroke. Further, in one traveling stroke in which the car 1 travels from the top floor 110 to the bottom floor 109, the pressure is increased according to the acceleration, the pressure is reduced near the maximum speed, and the pressure is reduced according to the deceleration. .. As a result, the amount of increase in atmospheric pressure per unit time is maintained at a predetermined value.

As described above, since the car 1 is provided with the car door 2 that can be opened and closed, even when the car door 2 is closed, there is a gap between the car door 2 and the members around the car door. There is a gap. Therefore, when the air pressure in the car 1 is pressurized and depressurized, if the inside and outside of the car 1 communicate with each other through the gap, the air pressure control efficiency by the air pressure control device is lowered. Therefore, the car 1 in the present embodiment has an airtight structure as described below.

FIG. 3 is a cross-sectional view showing the lower part of the car door of the car 1 shown in FIG.

The car door 2 includes panel members 2a and 2b arranged in pairs and facing each other, and a reinforcing member 6 fixed between the panel members 2a and 2b by bolts 5. The reinforcing member 6 ensures the desired strength of the car door 2. The car door 2 is configured to be able to open and close in the horizontal direction by being guided by a car sill 7 provided on the car floor while securing a predetermined gap between the car door 2 and the lower end of the car door 2. At the lower part of the car door 2, a shoe 10 attached to a bracket 9 connected to the car door 2 by a bolt 8 is provided. The shoe 10 is loosely fitted in a sill groove 7a provided in the car sill 7.

When the air pressure in the car 1 is pressurized and depressurized in the car door 2 in the closed state, the car door 2 closes the gap 11 located between the lower end of the car door 2 and the car sill 7. An airtight device 12 for sealing the car 1 is provided. The airtight device 12 has a flexible member 13 made of an elastic body as a main structural part thereof. In this embodiment, a rubber material is applied as the elastic body. The flexible member 13 extends over the entire width direction of the lower end of the car door 2 and elastically deforms in response to pressurization and depressurization in the car 1 to close the gap 11. As a result, the car 1 is sealed, so that the efficiency and accuracy of controlling the air pressure in the car 1 by the air pressure control device are improved.

FIG. 4 is an enlarged view of the lower part of the car door 2 shown in FIG.

In addition to the flexible member 13, the airtight device 12 includes a bracket 14, a rod member 15, a first holding tool 16, a second holding tool 17, and a nut 18.

The bracket 14 has an L-shaped cross-sectional shape and is fixed to the inner lower end of the panel material 2a. In the present embodiment, the L-shaped vertical side portion of the bracket 14 and the panel material 2a are adhered to each other by an adhesive. A threaded rod member 15 is erected on this vertical side portion.

The first presser 16 has an L-shaped cross-sectional shape, has an elongated hole 16a through which the rod member 15 is inserted, and is arranged inside the bracket 14. Further, the second holding tool 17 has an L-shaped cross-sectional shape and is arranged inside the first holding tool 16.

The first retainer 16 and the second retainer 17 are fixed to the bracket 14 by the rod member 15 and the nut 18 screwed into the rod member 15. A fixing portion 13a, which is an upper horizontal portion of the flexible member 13, is sandwiched between the horizontal piece of the first holding tool 16 and the horizontal piece of the second holding tool 17, whereby the flexible member 13 is placed in the car door 2. It is supported by the lower end of the.

The flexible member 13 has a fixed portion 13a, an upper movable portion 13b continuous with the fixed portion 13a, and a lower movable portion 13c continuous with the upper movable portion 13b.

The upper movable portion 13b faces the horizontal piece of the bracket 14 and forms an acute angle with the horizontal piece of the bracket 14. Therefore, at least in a normal time when the air pressure in the car 1 is not controlled, a wedge-shaped gap 19 is interposed between the horizontal piece of the bracket 14 and the upper movable portion 13b.

The lower movable portion 13c extends from one end of the upper movable portion 13b and faces the upper movable portion 13b. The lower movable portion 13c forms an acute angle with the upper movable portion 13b, and at least in a normal state, a wedge-shaped gap 20 is interposed between the upper movable portion 13b and the lower movable portion 13c. Further, the lower movable portion 13c normally faces the flat surface portion of the car sill 7 substantially in parallel, and a substantially horizontal gap portion 11a is interposed between the lower movable portion 13c and the car sill 7.

Since a predetermined gap is secured between the horizontal piece of the bracket 14 and the horizontal piece of the first holding tool 16, the position of the rod member 15 in the elongated hole 16a of the first holding tool 16 is moved. , The height position of the first holding tool 16 from the horizontal side of the bracket 14 can be adjusted. As a result, in the flexible member 13 sandwiched between the first holding tool 16 and the second holding tool 17, the height dimension of the gap portion 11a interposed between the lower movable portion 13c and the car sill 7 in a normal state. Can be adjusted. As a result, when the air pressure in the car 1 is pressurized and reduced, the flexible member 13 can reliably seal the car 1.

FIG. 5 is a partial perspective view showing the flexible member 13 shown in FIG. 4 and its peripheral members (that is, the airtight device 12 (FIG. 3)). In FIG. 5, the rod material 15, the elongated hole 16a, and the nut 18 shown in FIG. 4 are not shown.

The flexible member 13, the first presser 16 and the second presser 17 that sandwich the flexible member 13, and the rod material that the first presser 16 and the second presser 17 that sandwich the flexible member 13 are not shown. The bracket 14 fixed by the nut and the nut extends at the lower end of the car door in the width direction of the frontage of the car, that is, in the width direction of the car door (see FIG. 7). That is, in the present embodiment, the flexible member 13, the first holding tool 16, the second holding tool 17, and the bracket 14 are long bodies.

In the present embodiment, the flexible member 13 includes a fixed portion 13a, an upper movable portion 13b, a lower movable portion 13c, a vertical connecting portion 13d that connects the fixed portion 13a and the upper movable portion 13b, and an upper movable portion. It has a connecting portion 13e that connects the 13b and the lower movable portion 13c. The fixed portion 13a, the upper movable portion 13b, the lower movable portion 13c, the vertical connecting portion 13d, and the connecting portion 13e are integrally formed of a continuous elastic body.

Further, the reinforcing body 21 described later is embedded in the open end portion of the lower movable portion 13c (see FIGS. 3 and 4 (hatched portion)). Therefore, the entire surface of the reinforcing body 21 (horizontal plane (upper surface) and its back surface (lower surface), and each vertical surface (side surface)) is covered with an elastic body constituting the lower movable portion 13c. That is, the reinforcing body 21 is not exposed to the outside. In this embodiment, the flexible member 13 is molded from rubber. At the time of rubber molding, the reinforcing body 21 is embedded at the same time.

Since the reinforcing body 21 is embedded in the lower movable portion 13c in this way, the thickness of the lower movable portion 13c is set to a predetermined value larger than the thickness of the reinforcing body 21. Further, the thickness of the upper movable portion 13b and the lower movable portion 13c can be elastically deformed according to the pressurization and depressurization in the car 1, and the gap between the car door and the car sill can be closed. The size is set so that the amount of displacement that can be obtained can be obtained.

FIG. 6 is a partial perspective view showing the flexible member 13 and its peripheral members in the modified example of the present embodiment. The points different from the present embodiment (FIG. 5) will be described.

In this modification, the reinforcing body 21 is fitted into the recess on the upper surface of the lower movable portion 13c. This recess is opened in the horizontal surface portion of the lower movable portion 13c facing the gap portion interposed between the upper movable portion 13b and the lower movable portion 13c, that is, the upper surface of the lower movable portion 13c. Therefore, a part of the reinforcing body 21 is exposed to the outside. The back surface of the exposed horizontal surface of the reinforcing body 21 is covered with an elastic body constituting the lower movable portion 13c, as in the embodiment of FIG.

Also in this modification, the flexible member 13 is molded of rubber including the above-mentioned recesses. The reinforcing body 21 is pushed into the recess through the opening of the recess after rubber molding. As a result, the reinforcing body 21 is fitted to the lower movable portion 13c.

In this modification, the reinforcing body 21 is fixed to the lower movable portion 13c by being fitted to the lower movable portion 13c, but may be further fixed in the recess by using an adhesive. .. Further, in FIG. 6, the reinforcing body 21 projects from the upper surface of the lower movable portion 13c into a gap portion interposed between the upper movable portion 13b and the lower movable portion 13c. That is, the exposed horizontal plane of the reinforcing body 21 is located above the upper surface of the lower movable portion 13c. Not limited to this, the exposed horizontal plane of the reinforcing body 21 may be located below the upper surface of the lower movable portion 13c, that is, in the recess, or may be located in the same plane as the upper surface of the lower movable portion 13c.

FIG. 7 is a front view showing the flexible member 13 in FIG. This figure is a front view when the lower part of the car door 2 including the flexible member 13 and the car sill 7 are viewed from the inside of the car 1.

As shown in FIG. 7, in the flexible member 13, the lower end of the car door 2 is provided by a plurality of sets of rod members 15 and nuts 18 so that the longitudinal direction of the flexible member 13 is along the width direction of the car door 2. It is fixed to the part.

A plurality of reinforcing bodies 21 having a predetermined shape and a predetermined mass are arranged on the flexible member 13 along the longitudinal direction of the flexible member 13 at substantially equal intervals. The reinforcing body 21 is made of a plate-shaped or rectangular parallelepiped-shaped metal piece, and is embedded in the lower movable portion 13c of the flexible member 13 as described above. In the present embodiment, the reinforcing body 21 is made of a metal plate, but the present invention is not limited to this, and the mass density (hereinafter, simply referred to as “density”) is higher than that of the elastic body constituting the flexible member 13. It suffices if it is composed of a large material. For example, the flexible member 13 may be made of rubber and may be made of a resin having a higher density than the reinforcing body 21.

Next, the operation of the airtight device 12 including the flexible member 13 when the air pressure in the car 1 is controlled (pressurized or depressurized) by the air pressure control device will be described with reference to FIGS. 7 to 9.

FIG. 7 described above shows the state of the flexible member 13 including the reinforcing body 21 when the atmospheric pressure control device is not operated.

In the lower movable portion 13c where the reinforcing body 21 is embedded, the density of the reinforcing body 21 is higher than the density of the elastic body constituting the flexible member 13, and therefore, due to its own weight including the weight of the reinforcing body 21. Locally, it deforms or displaces toward the car sill 7, that is, downward. Therefore, as shown in FIG. 7, the lower movable portion 13c of the flexible member 13 has undulations at a predetermined interval corresponding to the interval of the reinforcing body 21 along the longitudinal direction of the lower movable portion 13c. However, it faces the horizontal plane of the car sill 7. When the air pressure control device is not operated, the lower movable portion 13c of the flexible member 13 is separated from the water surface of the car sill 7, and is lowered in the entire longitudinal direction of the lower movable portion 13c. There is a gap 11a between the side movable portion 13c and the car sill 7. Therefore, when the car 1 is stopped while the flexible member 13 is provided at the lower end of the car door 2, the car door 2 is smoothly opened and closed.

FIG. 8 is a front view showing the flexible member 13 at the initial stage during atmospheric pressure control.

When the pressure control device is operated from the state shown in FIG. 7 to pressurize the inside of the car 1, the inside of the car 1 is pressed in the gap 11a between the lower movable portion 13c of the flexible member 13 and the car sill 7. Since the air flow is generated toward the outside of the car 1, the air pressure in the gap 11a is lowered to become a negative pressure. Due to this negative pressure and the pressure difference pressure applied to the wedge-shaped gap 19 existing between the upper movable portion 13b and the horizontal side of the bracket 14, the upper movable portion 13b and the lower movable portion 13c are directed toward the car sill 7. Is pushed down.

At this time, as described above, the portion of the lower movable portion 13c in which the reinforcing body 21 is embedded is displaced downward from the portion in which the reinforcing body 21 is not embedded, so that the reinforcing body 21 is reinforced as shown in FIG. The body 21 comes into contact with the horizontal surface of the car sill 7 before the portion where the body 21 is not embedded. Therefore, when the portion in which the reinforcing body 21 is embedded comes into contact with the horizontal plane of the sill 7, there is still a gap 11a between the portion in which the reinforcing body 21 is not embedded and the car sill 7.

FIG. 9 is a front view showing the flexible member 13 when the atmospheric pressure control is advanced.

When the air pressure control proceeds from the state of FIG. 8 and the air pressure in the car 1 is pressurized, as shown in FIG. 9, the reinforcing body 21 is not embedded in addition to the portion where the reinforcing body 21 is embedded. The portion also comes into contact with the car sill 7. Therefore, the gap 11a is eliminated, and the car 1 is sealed. Since the gap 11a is eliminated, no negative pressure acts on the flexible member 13. Therefore, the restoring force of the flexible member 13 itself and the above-mentioned pressure difference pressure act on the flexible member 13. When the restoring force is larger than the pressure difference pressure, the flexible member 13 returns to the state shown in FIG. 11a occurs. The portion where the reinforcing body 21 is embedded is kept in contact with the car sill 7. In the portion where the reinforcing body 21 is not embedded, a negative pressure is generated again, and the flexible member 13 is pressed against the car sill 7 side by the negative pressure and the pressure difference pressure.

In the flexible member 13, the operating state of FIG. 8 and the operating state of FIG. 9 are alternately repeated until the pressure difference between the inside and outside of the car reaches a predetermined value by the atmospheric pressure control device. That is, chattering occurs in the operation of the flexible member 13. When chattering occurs, abnormal noise (vibration noise) is generated. In the present embodiment, the portion in which the reinforcing body 21 is embedded comes into contact with the car sill 7 before the portion in which the reinforcing body 21 is not embedded, and becomes a vibration node in the flexible member 13. As a result, vibrations associated with chattering are generated in the plurality of portions where the reinforcing body 21 is not embedded, that is, the plurality of portions narrower than the entire flexible member 13. As a result, the amplitude of vibration of the flexible member 13 can be reduced, and abnormal noise due to chattering can be reduced.

When the pressure difference between the inside and outside of the car reaches a predetermined value (control target value) by the pressure control device, a sufficient pressure difference pressure is applied to the upper movable portion 13b, and the portion where the reinforcing body 21 is embedded and the reinforcing body 21 are embedded. A state in which both portions are in contact with the car sill 7 is maintained. As a result, the abnormal noise is stopped and the airtight state of the car 1 is maintained.

When the air pressure in the car 1 is reduced, air is introduced from the outside of the car 1 toward the inside of the car 1 in the gap 11a between the lower movable portion 13c of the flexible member 13 and the car sill 7. The air pressure in the gap 11a drops and becomes a negative pressure. Further, a pressure difference pressure is applied to the wedge-shaped gap 20 existing between the upper movable portion 13b and the lower movable portion 13c. Therefore, a negative pressure, a pressure difference pressure, and a restoring force act on the flexible member 13 as in the case of pressurizing the air pressure in the car 1. Therefore, even when the air pressure in the car 1 is reduced, according to the present embodiment, it is possible to reduce the abnormal noise generated by the chattering in which the states of FIGS. 8 and 9 are repeated.

As described above, according to the present embodiment, by partially arranging the reinforcing body 21 which is a member having a higher density than the flexible member 13 on the flexible member 13, when the pressure is applied or the pressure is reduced. It is possible to reduce the abnormal noise generated by chattering.

Further, according to the present embodiment, by arranging the plurality of reinforcing bodies 21 intermittently along the longitudinal direction of the flexible member 13, it is possible to surely reduce the abnormal noise generated by chattering. Further, by arranging the plurality of reinforcing bodies 21 at equal intervals, the abnormal noise generated by the chattering is surely reduced, the chattering generated in the flexible member 13 is stabilized, and the passengers feel uncomfortable or uncomfortable. Can be suppressed. Therefore, it is possible to achieve noise reduction suitable for passengers.

By making the reinforcing body 21 made of metal, the density of the reinforcing body 21 can be increased to surely obtain a desired displacement amount in the flexible member 13, and it is possible to reduce the cost and improve the manufacturability. can.

Further, by embedding the reinforcing body 21 in the flexible member 13, the reinforcing body 21 can be reliably fixed to the flexible member 13, and the reinforcing body 21 and the flexible member 13 are integrated. The operation of the flexible member 13 can be stabilized.

The present invention is not limited to the above-described embodiment, and includes various modifications. For example, the above-described embodiment has been described in detail in order to explain the present invention in an easy-to-understand manner, and is not necessarily limited to the one including all the described configurations. Further, it is possible to add / delete / replace a part of the configuration of the embodiment with another configuration.

For example, the elastic body constituting the flexible member 13 may be a rubber material such as natural rubber or synthetic rubber, as well as a resin, a thin plate-shaped or foil-shaped metal.
