Detailed Description
Hereinafter, embodiments of the present invention will be described based on the drawings.
First, the structure of the elevator apparatus will be described with reference to fig. 6. Fig. 6 is a diagram showing a structure of an elevator apparatus according to an embodiment of the present invention.
The elevator apparatus 100 is housed inside a hoistway 2000 and a machine room 3000 provided in a building 1000. Inside the hoistway 2000, a car 101, a main rope 102, a counterweight 103, a guide rail 104, a speed control rope 105, a tension sheave 106b of a speed controller 106, and the like are disposed. Inside the machine room 3000, a traction sheave 107, a drive motor 112 for driving the traction sheave 107, a governor main body 106 having a sheave 106a, a control panel 17, and the like are arranged.
The car 101 is connected to one end of the main rope 102, and the counterweight 103 is connected to the other end of the main rope 102. The main hoist cable 102 is wound around a traction sheave 107, and the car 101 and the counterweight 103 are raised and lowered in the hoistway 2000 by driving the traction sheave 107 with a drive motor 112. Therefore, the main rope 102 is wound around the traction sheave 107 and is positioned inside the machine room 3000, and is stretched across the inside of the hoistway 2000 and the inside of the machine room 3000. The car 101 is guided to ascend and descend by guide rails 104 extending in the vertical direction (vertical line direction) inside the hoistway 2000.
A safety brake device 110 is provided in the car 101. The emergency brake device 110 grips the guide rail 700 with a wedge in an emergency to bring the car 101 to an emergency stop. One end of the rod 111 is pivotally supported on the car 101 side, and the other end is coupled to the speed control sling 1.
The speed control rope 105 is wound around between the sheave 106a and the tension sheave 106b, and is looped and tensioned over the entire elevator stroke section of the car 101 inside the elevator shaft 2000. The sheave 106a is provided inside the machine chamber 3000 together with the governor main body 106 c. Therefore, the speed adjusting rope 105 is stretched over the inside of the hoistway 2000 and the inside of the machine room 3000. The sheave 106a, the tension sheave 106b, and the governor main body 106c constitute a governor 106. The speed control rope 105 may be regarded as a component of the speed controller 106.
The control panel 17 manages each device constituting the elevator apparatus 100 in addition to the control of the drive motor 112.
The structure of the elevator apparatus 100 is not limited to the above-described structure, and other structures may be employed. For example, the elevator apparatus 100 may be configured such that the machine room 3000 is not provided, and equipment disposed inside the machine room 3000 is disposed inside the hoistway 2000. The elevator apparatus 100 may be configured such that the machine room 3000 is disposed below the hoistway 2000, for example.
Next, a car door provided in a car 101 of the elevator apparatus 100 will be described with reference to fig. 5. Fig. 5 is a front view showing a car door of an embodiment of the present invention.
The car 101 of the elevator apparatus 100 of the present embodiment includes car doors 1 that are disposed such that door-closing-side end portions thereof face each other at a door-closing position, and that operate in opposite directions to each other to open and close a car doorway 201. A car sill 2 for guiding movement of the car door 1 is fixed to a car floor of the car 101.
A door device housing 202 is fixed above the car doorway 201. A door rail 203 extending in the front width direction of the car doorway 201 is fixed to the door device housing 202. The car door 1 has a door hanger 204 fixed to an upper end portion of the car door 1, and a plurality of hanger rollers 205 provided on the door hanger 204 and rotating along a door rail 203. The car door 1 is suspended on the door rail 203 by the door hanger 204. The car doorway 201 is opened and closed by a pair of car doors 1 being guided and moved in a horizontal direction along the car sill 2 and the door rail 203 by a driving force of a door motor, not shown.
In addition, although the present embodiment exemplifies an elevator apparatus in which two doors are opened, the present invention can be applied to an elevator apparatus in which a single door is opened.
Next, the closing structure of the car door 1 will be described in detail with reference to fig. 1A, 1B, 2, 3A, 3B, and 4. Fig. 1A is a front view of a lower end of a car door of an elevator apparatus according to an embodiment of the present invention, as viewed from a landing side. Fig. 1B is a front view showing a lower end of the car door in a state where the car sill is removed from fig. 1A. Fig. 2 is a cross-sectional view taken along line II-II of fig. 1. Fig. 3A is a side view of the car door lower end portion as viewed from the direction III of fig. 1. Fig. 3B is a side view of the car door lower end portion shown by cutting a part of the 1 st pocket closing member 10a of fig. 3. Fig. 4 is a perspective view of a car sill according to an embodiment of the present invention, as viewed from obliquely above in the direction IV of fig. 2. Fig. 1A and 1B show a state in which the car doorway 201 is closed.
The car sill 2 is provided with a sill groove 3 extending in the front width direction of the car doorway 201, and a door shoe 4 attached to the lower end of the car door 1 is inserted therein. The door shoe 4 guides the lower end portion of the car door 1 when the car door 1 is opened and closed.
An intake blower and an exhaust blower as an air pressure control device 101A are provided on the upper part of the car 101. The air pressure control device 101A controls the intake blower, the exhaust blower, and the like to pressurize and depressurize the car 101 when the car 101 moves up and down in the hoistway 2000, so that the amount of change in the air pressure per unit time is kept constant. By this air pressure control, the sense of discomfort given to the passenger can be alleviated.
Further, since the car 101 is provided with the openable and closable car door 1 as described above, a gap is formed around the car door 1 even in a state where the car door 1 is closed, and the inside and the outside of the car 101 are easily communicated through the gap. When the inside and the outside of the car 101 communicate with each other through the gap, the efficiency of the air pressure control by the air pressure control device 101A is reduced.
In addition, the gap reduces the sound insulation of the car 101, and increases noise transmitted from the outside to the inside of the car 101.
In the elevator apparatus 100 according to the present embodiment, the car door 1 of the car 101 has a sealing structure that improves the sealing performance of the car 101. This sealing structure constitutes an airtight structure that improves the airtightness of the car 101, and also constitutes a sound insulation structure that improves the sound insulation of the car 101. Next, this sealing structure will be explained.
As shown in fig. 1A and 1B, a lower door air-tight member (a lower door closing member, a lower door sound insulating member) 5 that extends entirely across the width direction (front width direction) of the car door 1 and has a height dimension extending further below the sill surface 2a is provided at the lower portion of the car door 1. The door lower air-tight member 5 improves the air-tightness (sealing property) of the lower end portion of the car door 1, and improves the sound insulation property.
A closing plate (1 st closing plate) 6 extending entirely across the height direction thereof is disposed at a door opening side end portion (door pocket side end portion) 1a of the car door 1. As shown in fig. 2, the closing plate 6 has a crank-like horizontal cross section bent at right angles at 2, and one end in the horizontal direction thereof is attached to the door-opening-side end of the car door 1 by a closing plate fixing bolt 7. Further, an auxiliary closing plate (2 nd closing plate) 8 having an L-shaped cross section is attached to the other end portion of the closing plate 6 in the horizontal direction by a closing plate fastening bolt 9. When the door is closed, the closing plate 6 and the auxiliary closing plate 8 close the gap between the door-opening-side end 1a of the car door 1 and the door pocket 15.
Therefore, the 1 st door pocket airtight member (1 st closing plate airtight member) 10a is attached to the closing plate 6. The 1 st pocket airtight member 10a is held by the closing plate 6 between the closing plate 6 and the pocket-side end 1a of the car door 1. The 1 st pocket air-tight member has a height dimension extending further downward than the sill surface 2a, and a portion thereof abuts against the door opening side end surface 5a of the door lower air-tight member 5, and the other portion thereof abuts against the door opening side lower end surface of the car door 1 and abuts against the notch end surface 13a of the car sill 2 when the door is closed. The 1 st door pocket air-tight member 10a abuts on the notch end face 13a to seal the periphery of the door lower air-tight member groove (door lower closing member groove) 12, thereby improving air-tightness and sound insulation.
Further, a 2 nd door pocket airtight member (2 nd closing plate airtight member) 10b is attached to the auxiliary closing plate 8. A part of the 2 nd door pocket airtight member 10b abuts against a side surface of the 1 st door pocket airtight member 10a, and the other part abuts against a side portion (side surface) of the car column 11 forming a part of the car doorway 201 when the door is closed. The 2 nd door pocket airtight member 10b improves the sound insulation property by improving the airtightness (sealing property).
These airtight members 10a and 10b are molded from a viscoelastic material having excellent cushioning properties. The airtight member 10a is provided so as to be sandwiched between the closing plate 6 and the door-opening-side end portion 1a of the car door 1. In the present embodiment, the 1 st door pocket airtight member 10a and the 2 nd door pocket airtight member 10b are divided, but may be integrated.
The car column 11 forms a part of the car doorway 201, is disposed at an end of the door pocket 15 on the car doorway 201 side, and constitutes a part of the door pocket 15.
In the present embodiment, the door opening side refers to a side of a direction in which the car door 1 moves when the door to which the car door 1 is opened, that is, a side of a traveling direction when the door is opened, and the door closing side refers to a side of a direction in which the car door 1 moves when the car door 1 is closed, that is, a side of a traveling direction when the door is closed. Thus, the door-opening-side end portion of the car door 1 is the end portion of the car door 1 on the side in the direction of travel when the door is open. The door-opening-side end portion is sometimes referred to as a pocket-side end portion because it is located on the pocket side when the car door 1 is closed. An end portion on the opposite side of the car door 1 from the door-opening-side end portion is referred to as a door-closing-side end portion. The position of the door-closing-side end portion in the case where the car door 1 is in the closed state (door-closed state) is referred to as a door-closed position. A pair of car doors 1 is provided in the present embodiment. Accordingly, the two car doors 1 bring the door-closing-side ends of the car doors 1 into abutting contact with each other at the door-closing position to be in the door-closed state.
As shown in fig. 4, the car sill 2 is provided with a lower door air-tight member groove 12 for allowing the lower door air-tight member 5 to move and a sill door side notch 13 for allowing the 1 st door pocket air-tight member 10a to move. The door lower air-tight member groove 12 is an insertion groove for inserting the door lower air-tight member 5 into the lower end portion of the door lower air-tight member 5. The doorsill-side notch 13 is a retreat portion (recess) that avoids interference with the 1 st doorsill airtight member 10 a.
The sill-pocket-side notch 13 is formed in a range in which the door-opening-side end portion 1a of the car door 1, the 1 st pocket airtight member 10a, and the closing plate 6 move when the door is opened, from a portion where the door-opening-side end portion 1a of the car door 1 is located in the door-closed state. In the present embodiment, the sill-pocket-side notch 13 is formed from a portion where the door-opening-side end portion 1a of the car door 1 is located in the door-closed state to an end portion of the sill 2 in the traveling direction in which the door-opening-side end portion 1a of the car door 1 moves when the door is opened. The sill pocket side notch 13 may be formed from the upper surface 2a to the lower surface of the sill 2, and the longitudinal dimension of the side where the door lower airtight member groove 12 is formed can be made shorter than the longitudinal dimension of the side where the sill groove 3 is formed. In this case, the longitudinal dimension of the side where the door lower air-tight member groove 12 is formed can be set to a length that is about half of the longitudinal dimension of the side where the floor groove 3 is formed, and the material cost can be reduced.
The doorpocket-side notch 13 is formed in the doorsill 2, thereby forming a notch end face 13 a. The notched end surface 13a constitutes an abutment surface (sealing surface) against which the airtight member 10a abuts. When the door is closed (in a closed state), the 1 st door pocket airtight member 10a abuts against the cutaway end surface 13a, thereby closing the periphery of the gap formed between the groove 12 for the door lower airtight member and the upper surface 2a of the sill and the lower end portion of the car door 1, improving airtightness and sound insulation.
As shown in fig. 3, the door lower air-sealing member 5 includes flexible thin plate portions 5a and 5b that can elastically deform in accordance with the pressure increase and decrease in the car by the air pressure control device 101A and are in close contact with the side surfaces of the door lower air-sealing member groove 12, and a reinforcing portion 5c disposed between these flexible thin plate portions 5a and 5 b. The reinforcing portion 5c is disposed so that the longitudinal direction thereof is along the width direction (opening/closing direction) of the car door 1, and the flexible thin plate portions 5a and 5b are provided on both sides of the reinforcing portion 5c in the width direction of the door lower air-tight member groove 12.
The flexible thin plate portion 5b faces a side surface of the door lower air-tight member groove 12 on the side of the car room (the room of the car 101), and the flexible thin plate portion 5a faces a side surface of the door lower air-tight member groove 12 on the side of the boarding station. The flexible thin plate portions 5a and 5b are formed of rubber, for example, and are set to have a thickness dimension that can be elastically deformed without hindrance in accordance with pressurization and depressurization inside the car 2 by the air pressure control device 101A.
As shown in fig. 3A and 3B, an end face notch 14 capable of abutting the 1 st pocket air-tight member 10a against the door-open side end face of the door lower air-tight member 5 is formed in the pocket side end face 1a of the car door 1.
In the present embodiment, when the car door 1 is in the door closed state, the closing plate 6, the auxiliary closing plate 8, and the airtight members 10a and 10b close the gap between the door-opening-side end portion of the car door 1 and the door pocket 15 (the constituent member of the door pocket 15). At this time, the 1 st and 2 nd door pocket airtight members 10a and 10b abut against the door opening side end surface of the door lower airtight member 5, the door opening side lower end surface of the car door 1, and the side portion of the car pillar 11. In this manner, the gap below the door pocket is sealed by the 1 st door pocket airtight member 10a and the 2 nd door pocket airtight member 10 b.
In this state, when the air pressure in the car 101 is controlled by the air pressure control device 101A and the car 101 is pressurized, air passes from the inside of the car 101 to the outside, that is, from the left to the right in fig. 3A, through the gap between the door lower air-tight member 5 and the door lower air-tight member groove 12. Then, the flexible thin plate portion 5b is displaced by wind pressure in a direction away from the side surface of the door lower air-tight member groove 12 on the side of the car room. On the other hand, the flexible thin plate portion 5a is brought into contact with the side surface of the lower air-tight member groove 12 on the boarding station side by wind pressure. Since the flexible thin plate portion 5a abuts against the side surface of the door lower air-tight member groove 12, the gap is closed, and the flow of air is stopped. After the flow of air is stopped, the pressure is applied to the side surface of the flexible thin plate portion 5a by the pressure difference between the inside and the outside of the car 101, and the flexible thin plate portion 5a is further pressed toward the side surface of the door lower air-tight member groove 12. This improves the sealing performance of the car 101 and ensures airtightness.
When the interior of the car 101 is depressurized, air passes from the outside into the car 101, that is, from right to left in fig. 3, through the gap between the door lower air-tight member 5 and the door lower air-tight member groove 12. Then, the flexible thin plate portion 5a is displaced by wind pressure in a direction away from the side surface of the lower door air-tight member groove 12 on the boarding station side. On the other hand, the flexible thin plate portion 5b is brought into contact with the side surface of the lower air-tight member groove 12 on the car room side by wind pressure. Since the flexible thin plate portion 5b abuts against the side surface of the door lower air-tight member groove 12, the gap is closed, and the flow of air is stopped. After the flow of air is stopped, the pressure is applied to the side surface of the flexible thin plate portion 5b by the pressure difference between the inside and the outside of the car 101, and the flexible thin plate portion 5b is further pressed toward the side surface of the door lower air-tight member groove 12. This improves the sealing performance of the car 101 and ensures airtightness.
As described above, in the elevator apparatus of the present embodiment, the door lower air-tight member 5 has a height dimension extending further below the sill surface 2 a. Further, the car door 1 is attached with a 1 st pocket airtight member 10a having a height dimension extending further downward than the sill surface 2a, a part of which abuts against the door opening side end surface of the door lower airtight member 5, and the other part of which abuts against the door opening side lower end surface 1a of the car door 1, and a 2 nd pocket airtight member 10b, a part of which abuts against the side surface of the 1 st pocket airtight member 10a, and the other part of which abuts against the side portion of the car pillar 11 forming a part of the car doorway when the door is closed.
The 1 st and 2 nd door pocket airtight members 10a and 10b are mounted on the closing panel 6 and the auxiliary closing panel 8 attached to the lower end portion of the door opening side end surface 1a of the car door 1. The closing plate 6 and the auxiliary closing plate 8 are support members that mount the airtight members 10a, 10b and support the airtight members 10a, 10 b. Both the closing plate 6 and the auxiliary closing plate 8 are members that close the gap between the door-opening-side end portion 1a of the car door 1 and the door jamb 15, and may be regarded as an integral closing plate (closing plate member).
Further, the car sill 2 is provided with a lower door airtight member groove 12 for allowing the lower door airtight member 5 to move, and a sill door pocket side notch 13 for allowing the 1 st door pocket airtight member 10a to move. At this time, the 1 st door pocket airtight member 10a is disposed so as to abut against the notched end face 13a of the sill 2 formed by the sill-pocket-side notch.
This enables the gap below the door pocket and the gap below the car door 1 to be closed (sealed), thereby realizing a car with high sealing performance (airtightness).
In the present embodiment, the closing plate 6, the 1 st pocket airtight member 10a, the auxiliary closing plate 8, and the 2 nd pocket airtight member 10b extend in the height direction of the door opening side end portion 1a of the car door 1, and close the gap formed at the door opening side end portion 1a of the car door 1 (the gap between the door opening side end portion 1a of the car door 1 and the pocket 15) when the door is closed. Thus, the closing plate 6, the 1 st pocket airtight member 10a, the auxiliary closing plate 8, and the 2 nd pocket airtight member 10b constitute a door-opening side door end closing member of the car door 1. The closing plate 6 has an extension portion 6a extending downward from the upper surface 2a of the sill 2, and the 1 st door pocket air-tight member 10a extends upward from the opposite surface portion of the extension portion 6a to the notched end surface 13a of the sill 2.
The 1 st pocket gasproof member 10a is held by the closing plate (1 st closing plate) 6 between the closing plate 6 and the pocket-side end 1a of the car door 1, and is therefore reliably held by the car door 1. Further, the 1 st pocket airtight member 10a can reliably ensure airtightness (closure) between the closing plate 6 and the pocket-side end portion 1a and the door lower airtight member 5 of the car door 1. On the other hand, the 2 nd door pocket airtight member 10b is held by the auxiliary closing plate (2 nd closing plate) 8 so as to be in contact with the side portion of the car pillar 11 when the door is closed. Therefore, the 2 nd door pocket airtight member 10b can adjust the position of the 2 nd door pocket airtight member 10b with respect to the closing plate 6 and the 1 st door pocket airtight member 10a so as to be in close contact with the car column 11. This can reliably improve the airtightness (sealing property) of the car 101.
Further, the door lower air-tight member 5 includes the flexible thin plate portions 5a and 5b that are elastically deformable in accordance with the pressure increase and decrease in the car 101 by the air pressure control device 101A and come into close contact with the side surfaces of the door lower air-tight member groove 12, and thus the gap existing below the car door 1 can be sealed in accordance with the air pressure variation in the car 101 with a simple configuration without affecting the door opening and closing force of the car door 1.
Further, since the end surface notch 14 that allows the 1 st pocket air-tight member 10a to abut against the door opening side end surface of the door lower air-tight member 5 is formed in the pocket side end surface 1a of the car door 1, the 1 st pocket air-tight member 10a can be reliably brought into close contact with the door opening side end surface of the door lower air-tight member 5, and the air-tightness can be improved.
According to the present embodiment, the airtightness of the car 101 can be improved, and the air pressure in the car chamber can be controlled with high accuracy in accordance with the elevating speed. Therefore, the car 101 can be raised and lowered at a higher speed.
The present invention is not limited to the above-described embodiments, and includes various modifications. For example, the above-described embodiments are described in detail to explain the present invention easily and understandably, and are not limited to having all the structures described.
