Description

This specification relates to elevator cars and elevators.

Conventionally, for example, an elevator car includes a car frame, a car sheave around which a car rope is wound and which is connected to the car frame so as to be rotatable about an axis in the first horizontal direction, a stop movable part which can move between a standby position and a stop position where the car stops on the car rail, and an operating part which connects the governor rope to the stop movable part in order to operate the stop movable part (for example, Patent Document 1).

In the elevator car of Patent Document 1, the car sheave is disposed between the governor rope and the stop movable part in the first lateral direction. This requires the operating part to transmit the force of the governor rope to the stop movable part, which is disposed farther away than the car sheave.

In the elevator car of Patent Document 1, the operating unit is equipped with a rope connection part that is connected to the governor rope, and the rope connection part rotates with respect to the car frame around an axis in the second horizontal direction that is perpendicular to the first horizontal direction. As a result, when the rope connection part swings around an axis in the second horizontal direction, the governor rope vibrates in the first horizontal direction, so that the governor rope vibrates so as to approach and move away from the car rope. If the governor rope gets too close to the car rope, for example, there is a risk that the governor rope will come into contact with the car rope.

In each drawing, the dimensions of the components may be enlarged or reduced relative to their actual dimensions, for example, to facilitate understanding, and the dimensional ratios between the drawings may not be consistent. In each drawing, some of the components may be omitted, for example, to facilitate understanding.

Terms including ordinal numbers such as first and second are used to describe various components, but these terms are used only for the purpose of distinguishing one component from another, and the components are not particularly limited by these terms. Note that the number of components including ordinal numbers is not particularly limited, and may be, for example, one. Also, the ordinal numbers used in the following specification and drawings may differ from the ordinal numbers described in the claims.

As shown in FIG. 1, the elevator 1 may include, for example, an elevator car (hereinafter, simply referred to as "car") 10 for people (passengers) to ride in, a car rope 2 connected to the car 10, a counterweight 3 connected to the car rope 2, a hoist 4 that drives the car rope 2 to move the car 10 and the counterweight 3 in the vertical direction D3, a car rail 5 that guides the car 10, a counterweight rail 6 that guides the counterweight 3, and a speed governor 7 that detects the traveling speed of the car 10.

In each figure, the first direction D1 is the first horizontal direction D1, the second direction D2 is the second horizontal direction D2 that is a horizontal direction perpendicular to the first horizontal direction D1, and the third direction D3 is the up-down direction D3 that is perpendicular to each of the horizontal directions D1 and D2, and is the lifting direction in which the car 10 and the counterweight 3 rise and fall.

The hoisting machine 4 may include, for example, as in this embodiment, a sheave 4a around which the car rope 2 is wound, a drive source 4b (e.g., a motor) that rotates the sheave 4a, and a braking unit 4c that brakes the sheave 4a. Note that the elevator 1 according to this embodiment is configured such that the hoisting machine 4 is disposed inside the hoistway X1, but is not limited to this configuration. For example, the elevator 1 may be configured such that the hoisting machine 4 is disposed inside a machine room provided above the hoistway X1.

The governor 7 is provided with an endless looped governor rope 7a connected to the car 10 so as to run in conjunction with the movement of the car 10. The governor 7 may also be provided with, for example, a governor wheel 7b around which the governor rope 7a is wound, a tension wheel 7c suspended from the governor rope 7a to apply tension to the governor rope 7a, and a governor stopper 7d that stops the running of the governor rope 7a when the car 10 moves downward at a set speed, as in this embodiment.

The configuration of the governor stop unit 7d is not particularly limited. For example, when the car 10 moves downward at a set speed and the governor wheel 7b rotates at a set rotational speed, the governor stop unit 7d may be configured to grip the governor rope 7a to stop the governor rope 7a from traveling. Note that the set speed may be, for example, higher than the rated speed of the car 10 (the maximum speed during normal operation), and may be, for example, 110% to 120% of the rated speed of the car 10.

As shown in Figures 1 to 4, the car 10 includes a car frame 11, car sheaves 12, 13 around which the car rope 2 is wound and which are rotatably connected to the car frame 11 about an axis in the first horizontal direction D1, and a stopping device 20 that stops the car 10 on the car rail 5. Note that the number of car sheaves 12, 13 is not particularly limited. The number of car sheaves 12, 13 may be, for example, two, or may be, for example, one or three or more.

The car 10 may also include, for example, a car chamber 14 for passengers to ride in, and guide rollers 15 that are guided by the car rails 5, as in this embodiment. The car frame 11 may also be fixed to the car chamber 14, as in this embodiment.

In addition, in Figures 1 to 4, the car frame 11 is only shown below the car chamber 14, but the car frame 11 may be arranged, for example, around the car chamber 14. Specifically, the car frame 11 may be arranged, for example, below, above, and to the sides of the car chamber 14. In addition, the car frame 11 may have multiple frame materials, for example, as in this embodiment.

As shown in Figures 2 to 7, the stopping device 20 includes a first stop movable part 21 that is movable between a standby position and a stop position where the car 10 is stopped on the car rail 5, and a first operating part 30 that connects the governor rope 7a and the first stop movable part 21 to operate the first stop movable part 21. The first car sheave 12 is disposed between the governor rope 7a and the first stop movable part 21 in the first horizontal direction D1.

The stop device 20 may also include, for example, as in this embodiment, a second stop movable part 22 that is movable between a standby position and a stop position that stops the car 10 on the car rail 5, first and second stop fixed parts 23, 24 that are fixed to the car frame 11, and a second operating part 50 that connects the first operating part 30 and the second stop movable part 22 to operate the second stop movable part 22.

The stop movable parts 21, 22 may be movable relative to the stop fixed parts 23, 24, for example, between a stop position and a standby position lower than the stop position. The stop position is the position shown by the two-dot chain line in FIG. 7, and the standby position is the position shown in FIGS. 2 to 6 and the position shown by the solid line in FIG. 7.

For example, when the car 10 moves downward at a set speed, the governor stop part 7d (see FIG. 1) stops the governor rope 7a from running and the car 10 moves downward, so that the stop movable parts 21, 22 move from the standby position to the stop position. After that, for example, when the stop movable parts 21, 22 are located at the stop position, the stop movable parts 21, 22 cooperate with the stop fixed parts 23, 24 to pressurize and contact the car rail 5, so that the car 10 stops on the car rail 5.

As shown in Figures 5 to 8, the first operating unit 30 includes a first rotating unit 31 rotatably connected to the car frame 11, a second rotating unit 32 rotatably connected to the car frame 11 and separate from the first rotating unit 31, and a first operating connection unit 33 that connects the first rotating unit 31 and the second rotating unit 32. In addition, the first operating unit 30 may include, for example, a force application unit 34 that applies a force to the stop movable units 21 and 22 toward the standby position, as in this embodiment.

The first rotating part 31 includes a rope connection part 35 connected to the governor rope 7a, and a first rotating shaft part 36 to which the rope connection part 35 is fixed and which is connected to the cage frame 11 so as to be rotatable about an axis in the first horizontal direction D1. For example, as in this embodiment, the governor rope 7a may be connected to the rope connection part 35 so as to be rotatable about an axis in the first horizontal direction D1.

The second rotating part 32 includes a first stop connection part 37 connected to the first stop movable part 21, and a second rotating shaft part 38 to which the first stop connection part 37 is fixed and which is connected to the car frame 11 so as to be rotatable about the first horizontal direction D1 as an axis. For example, as in this embodiment, the first stop movable part 21 may be connected to the first stop connection part 37 so as to be rotatable about the first horizontal direction D1 as an axis.

In this way, the first rotating shaft portion 36 to which force is transmitted from the governor rope 7a and the second rotating shaft portion 38 which transmits force to the first stop movable portion 21 are separate bodies. As a result, while the rope connection portion 35 and the first stop connection portion 37 are far apart in the first lateral direction D1, for example, the length of the rotating shaft portions 36, 38 can be shortened. Therefore, the mechanical strength required for the rotating shaft portions 36, 38 can be reduced.

Moreover, for example, the arrangement of the first rotating shaft portion 36 and the second rotating shaft portion 38 can be flexibly accommodated, which improves the freedom of design of the cage 10. For example, as in this embodiment, the first rotating shaft portion 36 and the second rotating shaft portion 38 may be configured to be separated from each other when viewed in the first horizontal direction D1. Also, for example, as in this embodiment, the first rotating shaft portion 36 and the second rotating shaft portion 38 may be configured to be separated from each other when viewed in the second horizontal direction D2 and the up-down direction D3.

In addition, for example, the positions of the first rotating shaft portion 36 and the second rotating shaft portion 38 can be designed taking into account the position of the first car sheave 12. For example, the lower end of the first car sheave 12 is the lower end of the car 10. In contrast, the upper end of the car sheave 12 is positioned higher than the second rotating shaft portion 38. This prevents the lower end of the car sheave 12 from moving too far downward from the car frame 11, thereby preventing the dimension of the elevator car 10 in the vertical direction D3 from becoming too large.

A portion of the first cage sheave 12 is positioned outside the end position 11b of the cage frame 11 in the second horizontal direction D2. In contrast, the second rotating shaft portion 38 is spaced apart from the first cage sheave 12 when viewed in the second horizontal direction D2, and overlaps with the first cage sheave 12 when viewed in the first horizontal direction D1. As a result, the second rotating shaft portion 38 is positioned in the region of the end of the cage frame 11 in the second horizontal direction D2, which prevents the length of the first stop connection portion 37 from becoming too long.

For example, as in this embodiment, the first rotating shaft portion 36 may overlap the first cage sheave 12 when viewed in the up-down direction D3, and may be separated from the first cage sheave 12 when viewed in the first horizontal direction D1 and the second horizontal direction D2. For example, as in this embodiment, the second rotating shaft portion 38 may overlap the first cage sheave 12 when viewed in the first horizontal direction D1, and may be separated from the first cage sheave 12 when viewed in the second horizontal direction D2 and the up-down direction D3.

The number of first stop movable parts 21 is not particularly limited, and may be, for example, two as in this embodiment, or may be, for example, one or three or more. The number of first stop connection parts 37 is not particularly limited, and may be, for example, two as in this embodiment, or may be, for example, one or three or more.

The first operational connection part 33 includes a first shaft fixing part 39 fixed to the first rotating shaft part 36, a second shaft fixing part 40 fixed to the second rotating shaft part 38, and a first fixed connection part 41 rotatably connected to the first shaft fixing part 39 around the first horizontal direction D1 as an axis, and rotatably connected to the second shaft fixing part 40 around the first horizontal direction D1 as an axis. As a result, the first shaft fixing part 39 and the second shaft fixing part 40 are connected by the first fixed connection part 41.

The second operating unit 50 may, for example, as in this embodiment, include a third rotating unit 51 rotatably connected to the car frame 11, and a second operating connection unit 52 that connects the third rotating unit 51 to the second rotating unit 32 of the first operating unit 30. The third rotating unit 51 may, for example, as in this embodiment, include a second stop connection unit 53 that is connected to the second stop movable unit 22, and a third rotating shaft unit 54 to which the second stop connection unit 53 is fixed and which is rotatably connected to the car frame 11 about an axis in the first horizontal direction D1.

The second stop movable part 22 may be connected to the second stop connection part 53 so as to be rotatable about the first horizontal direction D1 as an axis, as in the present embodiment. The number of second stop movable parts 22 is not particularly limited, and may be, for example, two as in the present embodiment, or may be, for example, one or three or more. The number of second stop connection parts 53 is not particularly limited, and may be, for example, two as in the present embodiment, or may be, for example, one or three or more.

The second operating connection part 52 may, for example, as in this embodiment, include a third shaft fixing part 55 fixed to the second rotating shaft part 38 of the first operating part 30, a fourth shaft fixing part 56 fixed to the third rotating shaft part 54, and a second fixed connection part 57 rotatably connected to the third shaft fixing part 55 around the first horizontal direction D1 as an axis and rotatably connected to the fourth shaft fixing part 56 around the first horizontal direction D1 as an axis. As a result, the third shaft fixing part 55 and the fourth shaft fixing part 56 are connected by the second fixed connection part 57.

The operating units 30, 50 may include bearings 42, 58 that rotatably connect the rotating shafts 36, 38, 54 to the car frame 11, as in this embodiment. Although not particularly limited, the bearings 42, 58 may be, for example, bushes (slide bearings) or bearings. The rotating shafts 36, 38, 54 may be inserted into the through holes 11a of the car frame 11, as in this embodiment.

Here, we will explain the operation of the stopping device 20.

For example, when the governor stop portion 7d (see FIG. 1) stops the governor rope 7a from running and the car 10 moves downward, the rope connection portion 35 and the first rotating shaft portion 36 rotate about the first horizontal direction D1. As a result, the second rotating shaft portion 38 and the first stop connection portion 37 rotate about the first horizontal direction D1, and the third rotating shaft portion 54 and the second stop connection portion 53 rotate about the first horizontal direction D1. Therefore, the first stop movable portion 21 and the second stop movable portion 22 move from the standby position to the stop position.

Since the rope connection part 35 rotates integrally with the first rotating shaft part 36, the rope connection part 35 rotates around an axis in the first horizontal direction D1 relative to the car frame 11. Therefore, for example, when the rope connection part 35 swings due to the car 10 accelerating or vibrating, the governor rope 7a vibrates in the second horizontal direction D2.

This makes it possible to suppress changes in the distance between the governor rope 7a and the car rope 2 (see FIG. 4). As a result, in a configuration in which the first car sheave 12 is disposed between the governor rope 7a and the first stop movable part 21, even if the rope connection part 35 swings, it is possible to suppress the governor rope 7a from vibrating so as to approach the car rope 2.

The first and second rotating parts 31, 32 rotatably connected to the car frame 11 are rotatably connected to the car frame 11 around an axis in the first horizontal direction D1. Specifically, all of the rotating parts 31, 32 of the first operating unit 30 are rotatably connected to the car frame 11 around an axis in the first horizontal direction D1.

As a result, when the rope connection part 35 swings, the first and second rotating parts 31, 32 swing about the first horizontal direction D1 as an axis, and therefore it is possible to suppress a change in the distance between the first and second rotating parts 31, 32 and the first cage sheave 12. Therefore, even when the rope connection part 35 swings, it is possible to suppress the first and second rotating parts 31, 32 from swinging closer to the first cage sheave 12.

The third rotating part 51, which is rotatably connected to the car frame 11, is also rotatably connected to the car frame 11 around its axis in the first horizontal direction D1. As a result, when the rope connection part 35 swings, the third rotating part 51 swings around its axis in the first horizontal direction D1, so that it is possible to suppress a change in the distance between the third rotating part 51 and the second car sheave 13. Therefore, even when the rope connection part 35 swings, it is possible to suppress the third rotating part 51 from swinging closer to the second car sheave 13.

Next, the specific configuration of the first operating unit 30 will be described with reference to Figures 8 and 9.

As shown in FIG. 8, the first fixed connection part 41 is connected to the first shaft fixing part 39 at the first rotation center position 41a so as to be rotatable around the first horizontal direction D1 as an axis. The first fixed connection part 41 is connected to the second shaft fixing part 40 at the second rotation center position 41b so as to be rotatable around the first horizontal direction D1 as an axis.

When viewed in the first horizontal direction D1, the first straight line L1 connecting the first rotation center position 41a and the first shaft center position 36a of the first rotating shaft portion 36 is parallel to the second straight line L2 connecting the second rotation center position 41b and the second shaft center position 38a of the second rotating shaft portion 38. Moreover, when viewed in the first horizontal direction D1, the third straight line L3 connecting the first rotation center position 41a and the second rotation center position 41b is parallel to the fourth straight line L4 connecting the first shaft center position 36a and the second shaft center position 38a.

Therefore, when viewed in the first horizontal direction D1, the first to fourth straight lines L1 to L4 form a parallelogram. When viewed in the first horizontal direction D1, the length of the first straight line L1 (the distance between the first rotation center position 41a and the first axis center position 36a) is the same as the length of the second straight line L2 (the distance between the second rotation center position 41b and the second axis center position 38a), and the length of the third straight line L3 (the distance between the first rotation center position 41a and the second rotation center position 41b) is the same as the length of the fourth straight line L4 (the distance between the first axis center position 36a and the second axis center position 38a).

As a result, as shown in FIG. 9, the rotation angle θ1 of the first rotating shaft portion 36 and the rotation angle θ2 of the second rotating shaft portion 38 become the same. This makes it possible to, for example, facilitate the design of the first operating portion 30. Note that in this specification, "parallel" does not only mean completely parallel, but also includes approximately parallel where the intersection angle is 5° or less.

The first motion connection part 33 is also positioned inside the end position 11b of the car frame 11 in the second horizontal direction D2. This makes it possible to prevent the first motion connection part 33 from protruding from the end position 11b of the car frame 11 in the second horizontal direction D2. Therefore, for example, it is possible to prevent the first motion connection part 33 from colliding with parts in the elevator shaft X1. Although not particularly limited, for example, as in this embodiment, the respective lengths of the first straight line L1 and the second straight line L2 may be shorter than the respective lengths of the third straight line L3 and the fourth straight line L4.

For example, but not limited to, in this embodiment, the first rotating shaft portion 36, the second rotating shaft portion 38, the first shaft fixing portion 39, the second shaft fixing portion 40, and the first fixed connection portion 41 are each positioned inward from the end position 11b of the car frame 11 in the second horizontal direction D2. This makes it possible to reduce, for example, the portion of the first operating portion 30 that protrudes from the end position 11b of the car frame 11 in the second horizontal direction D2.

[1]
From the above, the elevator car 10, as in this embodiment,
An elevator car 10 that travels in a vertical direction D3 by being guided by a car rail 5,
A cage frame 11;
a car sheave (in this embodiment, a first car sheave) 12 around which the car rope 2 is wound and which is connected to the car frame 11 so as to be rotatable about an axis in the first horizontal direction D1;
A stop device 20 that stops the elevator car 10 on the car rail 5,
The stopping device 20 is
a stop movable part (in this embodiment, a first stop movable part) 21 that is movable from a standby position to a stop position where the elevator car 10 is stopped on the car rail 5;
and an operating section (in this embodiment, a first operating section) 30 that connects the governor rope 7a and the stop movable section 21 in order to operate the stop movable section 21.
The cage sheave 12 is disposed between the governor rope 7a and the stop movable portion 21 in the first horizontal direction D1,
The operating unit 30 includes a rope connecting portion 35 connected to the governor rope 7a.
The rope connection portion 35 rotates about an axis in the first horizontal direction D1 relative to the car frame 11.
This configuration is preferred.

With this configuration, the rope connection part 35 rotates around the first horizontal direction D1 relative to the cage frame 11. As a result, when the rope connection part 35 swings, the governor rope 7a vibrates in the second horizontal direction D2.

This makes it possible to suppress changes in the distance between the governor rope 7a and the car rope 2. As a result, in a configuration in which the car sheave (in this embodiment, the first car sheave) 12 is disposed between the governor rope 7a and the stop movable part (in this embodiment, the first stop movable part) 21, even if the rope connection part 35 swings, it is possible to suppress the governor rope 7a from vibrating so as to approach the car rope 2.

[2]
In addition, in the elevator car 10 of the above [1], as in this embodiment,
The operating section (in this embodiment, the first operating section) 30 is
A first rotating portion 31 including the rope connection portion 35;
a second rotating portion 32 separate from the first rotating portion 31;
An operational connection portion (in this embodiment, a first operational connection portion) 33 that connects the first rotating portion 31 and the second rotating portion 32,
The first rotating portion 31 includes a first rotating shaft portion 36 to which the rope connection portion 35 is fixed and which is connected to the car frame 11 so as to be rotatable about an axis in the first horizontal direction D1,
The second rotating portion 32 is
A stop connection part (in this embodiment, a first stop connection part) 37 connected to the stop movable part (in this embodiment, a first stop movable part) 21;
a second rotating shaft portion 38 to which the stop connection portion 37 is fixed and which is connected to the car frame 11 so as to be rotatable about an axis in the first horizontal direction D1;
This configuration is preferred.

With this configuration, the first rotating shaft part 36 to which force is transmitted from the governor rope 7a and the second rotating shaft part 38 which transmits force to the stop movable part (in this embodiment, the first stop movable part) 21 can be made separate. The operation connection part (in this embodiment, the first operation connection part) 33 connects the first rotating part 31 and the second rotating part 32.

As a result, the rope connection part 35 and the first rotating shaft part 36 rotate around the axis in the first horizontal direction D1 by the governor rope 7a, and the second rotating shaft part 38 and the stop connection part (in this embodiment, the first stop connection part) 37 rotate around the axis in the first horizontal direction D1. Therefore, the stop movable part 21 moves from the standby position to the stop position.

In addition, because the second rotating shaft portion 38 is connected to the car frame 11 so as to be rotatable about the axis in the first horizontal direction D1, when the rope connection portion 35 swings, the stop connection portion (in this embodiment, the first stop connection portion) 37 swings about the axis in the first horizontal direction D1. This makes it possible to suppress changes in the distance between the stop connection portion 37 and the car sheave (in this embodiment, the first car sheave) 12. Therefore, even when the rope connection portion 35 swings, it is possible to suppress the stop connection portion 37 from swinging closer to the car sheave 12.

[3]
In addition, in the elevator car 10 of the above [2], as in this embodiment,
The lower end of the car sheave (in this embodiment, the first car sheave) 12 is the lower end of the elevator car 10,
The upper end of the cage sheave 12 is disposed above the second rotating shaft portion 38.
This configuration is preferred.

With this configuration, the upper end of the car sheave 12 is positioned above the second rotating shaft portion 38, which prevents the lower end of the car sheave 12 from moving too far downward from the car frame 11. This prevents the vertical dimension of the elevator car 10 from becoming too large.

[4]
In addition, in the elevator car 10 of the above [3], as in this embodiment,
A part of the cage sheave (in this embodiment, a first cage sheave) 12 is disposed on the outside of an end position 11b of the cage frame 11 in the second horizontal direction D2,
The second rotating shaft portion 38 is spaced from the cage sheave 12 when viewed in a second horizontal direction D2 perpendicular to the first horizontal direction D1,
The second rotating shaft portion 38 overlaps with the cage sheave 12 when viewed in the first horizontal direction D1.
This configuration is preferred.

With this configuration, the second rotating shaft portion 38 overlaps with the cage sheave 12 when viewed in the first horizontal direction D1, so the second rotating shaft portion 38 is disposed in the region of the end of the cage frame 11 in the second horizontal direction D2. This makes it possible to prevent the length of the stop connection portion (in this embodiment, the first stop connection portion) 37 from becoming too long.

[5]
In addition, in any one of the elevator cars 10 described above in [2] to [4], as in this embodiment,
The operational connection portion (in this embodiment, the first operational connection portion) 33 is
a first shaft fixing portion 39 fixed to the first rotating shaft portion 36;
a second shaft fixing portion 40 fixed to the second rotating shaft portion 38;
a fixed connection portion (in this embodiment, a first fixed connection portion) 41 that is connected to the first shaft fixing portion 39 at a first rotation center position 41 a so as to be rotatable about an axis in the first horizontal direction D1, and that is connected to the second shaft fixing portion 40 at a second rotation center position 41 b so as to be rotatable about an axis in the first horizontal direction D1,
When viewed in the first horizontal direction D1, a straight line L1 connecting the first rotation center position 41 a and a first shaft center position 36 a of the first rotating shaft portion 36 (in this embodiment, a first straight line) is parallel to a straight line L2 connecting the second rotation center position 41 b and a second shaft center position 38 a of the second rotating shaft portion 38 (in this embodiment, a second straight line).
When viewed in the first horizontal direction D1, a straight line L3 connecting the first rotation center position 41 a and the second rotation center position 41 b (in this embodiment, a third straight line) is parallel to a straight line L4 connecting the first axis center position 36 a and the second axis center position 38 a (in this embodiment, a fourth straight line).
This configuration is preferred.
