Note that the elevator 1 may be configured to use a rope-type drive system, for example, or may be configured to use a hydraulic drive system, for example.

In each figure, the first direction D1 is a first lateral direction D1 that is parallel to the horizontal direction, and the second direction D2 is a direction that is parallel to the horizontal direction and is the same as the first lateral direction D1. The second lateral direction D2 is orthogonal to each other, and the third direction D3 is a vertical direction that is orthogonal to the first lateral direction D1 and the second lateral direction D2, and is an up-down direction D3.

Although not shown, the input unit 6 may include, for example, an operation panel located inside the car 2, a landing, etc., and operated by a passenger, and a maintenance panel operated by a maintenance worker. For example, the maintenance panel may be permanently installed outside the car 2, or may be electrically removable from, for example, the processing device 5. Further, the operation panel may be input with, for example, door opening/closing instruction information, destination floor instruction information, destination direction instruction information, etc., and the maintenance panel may be input with, for example, maintenance-related information (e.g., up/down instruction information for car 2). etc.) may be input.

Although not shown, the output section 7 includes, for example, an output panel disposed inside the car 2 and at the landing, and a transmitting means for transmitting information to an external device (for example, a central monitoring device, etc.). You can. Although not particularly limited, the output board may include, for example, an audio section (for example, a buzzer, a speaker), a display section (for example, a display board, an indicator light), and the like.

For example, as in the present embodiment, the processing device 5 controls each unit, such as an acquisition unit 5a that acquires each piece of information (data), a storage unit 5b that stores each piece of information, and a calculation unit 5c that calculates each piece of information. The control unit 5d may also be provided with a control unit 5d. The acquisition unit 5a may acquire information, for example, by receiving information input to the input unit 6 or transmitted from an external device (for example, a central monitoring device).

The processing device 5 may be composed of, for example, one device, or may be composed of, for example, a plurality of devices that can communicate with each other. Specifically, each of the units 5a to 5d of the processing device 5 may be included in one device, or may be distributed and provided in a plurality of devices that can communicate with each other, for example.

Note that the processing device 5 includes processors such as a CPU and MPU (e.g., arithmetic unit 5c, control unit 5d), memories such as ROM and RAM (e.g., acquisition unit 5a, storage unit 5b), various interfaces (e.g., acquisition unit 5a) and the like. Each section 5a to 5d of the processing device 5 is realized by the processor executing the program stored in the memory and the software and hardware working together.

As shown in FIGS. 1 to 3, the linear motor 3, which is the car drive unit 3, is connected to a motor stator 3a fixed to the hoistway and the car 2, for example, as in the present embodiment, It may also include a motor movable element 3b that is movable with respect to the motor stator 3a. For example, the motor mover 3b may include a magnet, and the motor stator 3a may include a coil that applies electromagnetic force in the vertical direction D3 to the magnet.

Although not particularly limited, in the elevator 1, for example, as in this embodiment, the linear motor 3 may be provided so as to sandwich the car 2 in the second lateral direction D2. Further, although not particularly limited, in each linear motor 3, the motor movers 3b may be provided separately in the vertical direction D3, for example, as in the present embodiment.

For example, as in the present embodiment, the car 2 includes a car main body 8 having a car chamber 8a and a car frame 8b, and first and second car parts connected to a motor mover 3b and guided by car rails 4a to 4d. The car may include car guide parts 9 and 10, a car connection part 2a that connects the car guide parts 9 and 10 to the car body part 8, and a speed detection part 11 that detects the running speed of the car 2.

The car connecting part 2a connects the car guide parts 9, 10 and the car main body part 8, for example, as in the present embodiment, so that the car guide parts 9, 10 are movable relative to the car main body part 8. You can leave it there. Thereby, for example, it is possible to suppress the vibrations of the car guide parts 9 and 10 from being transmitted to the car chamber 8a of the car main body part 8. Although not particularly limited, the car connecting portion 2a may be made of, for example, an elastic member (eg, laminated rubber, etc.).

The first and second car guide portions 9 and 10 may be arranged to sandwich the car 2 in the second lateral direction D2, for example, as in the present embodiment. In this embodiment, since one linear motor 3 is provided with a pair of motor movers 3b separated in the vertical direction D3, each of the first and second car guide portions 9 and 10 also A pair may be provided separated in the vertical direction D3.

The car guide parts 9 and 10 are, for example, as in the present embodiment, guide frame parts 9a and 10a fixed to the car connection part 2a, and connected to the guide frame parts 9a and 10a, and guided to the car rails 4a to 4d. The guided portions 9b and 10b may be provided. Although not particularly limited, the guided portions 9b and 10b may be rollers guided by the car rails 4a to 4d, for example, as in this embodiment.

Although not particularly limited, the rollers include rollers that hit the car rails 4a to 4d in the first lateral direction D1 and rollers that hit the car rails 4a to 4d in the second lateral direction D2, and the rotation axis of each roller For example, the position may be unchangeable and fixed relative to the guide frames 9a, 10a. Thereby, it is possible to suppress the car guide parts 9 and 10 from moving in the lateral directions D1 and D2 with respect to the car rails 4a to 4d.

The number of car rails 4a to 4d is not particularly limited, and may be two, for example, or may be four, as in this embodiment. Specifically, for example, as in the present embodiment, the car rails 4a to 4d include first and third car rails 4a, 4c that guide the first car guide section 9, and guide the second car guide section 10. The second and fourth car rails 4b and 4d may also be included.

The first and third car rails 4a and 4c and the second and fourth car rails 4b and 4d may be separated in the second lateral direction D2 so that the car 2 is sandwiched therebetween. Furthermore, the first and third car rails 4a and 4c may be separated, for example, in the first lateral direction D1, and the second and fourth car rails 4b and 4d may be separated, for example, in the first lateral direction D1. You can be far away.

The configuration of the speed detection section 11 is not particularly limited. For example, the speed detection unit 11 may detect the traveling speed of the car 2 by detecting a plurality of detected parts (not shown) arranged in the vertical direction D3 on the car rail 4a. Further, for example, the speed detection unit 11 may detect the running speed of the car 2 by detecting the rotation of a rotating body (for example, a governor roller 22a described later) that is in contact with the car rails 4a to 4d.

As shown in FIGS. 2 and 3, the elevator 1 may be equipped with a stopping device 12 that stops the car 2 on the car rails 4a to 4d, for example, as in the present embodiment. The stopping device 12 may be attached to the car 2 and move together with the car 2, for example, as in this embodiment. The device including the car 2 and the stop device 12 is called an elevator car device 1a, and the elevator car device 1a travels in the vertical direction D3 by being guided by the car rails 4a to 4d.

For example, as in the present embodiment, the stop device 12 is connected to a plurality of stop parts 13 such that the plurality of stop parts 13 interlock with each other, and transmits force to the plurality of stop parts 13. The transmission unit 14 may also be provided. In this embodiment, the stopping device 12 is connected to the first and second car guide sections 9 and 10 on the lower side, but for example, the stopping device 12 is connected to the first and second car guide sections 9 and 10 on the upper side. may have been done.

The number of stop parts 13 is not particularly limited, and may be two, for example, or may be four as in this embodiment, as long as the number can stop the car 2 on the car rails 4a to 4d. good. Further, for example, as in this embodiment, the number of stop portions 13 may be the same as the number of car rails 4a to 4d.

Each stop part 13 is connected to a stop fixing part 15 fixed to the car guide parts 9 and 10 and a transmission part 14, and is movable with respect to the stop fixing part 15, for example, as in the present embodiment. It may also include a stop movable part 16. The stop movable part 16 has, for example, a stop position (see FIG. 5) where it comes into contact with the stop fixing part 15 and cooperates with the stop fixing part 15 to stop the car 2, and a standby position below the stop position (see FIG. 3). and FIG. 4) may be movable with respect to the stop fixing part 15.

For example, as in the present embodiment, the transmission section 14 is fixed to the first and second shafts 14a, 14b that are rotatable about the first lateral direction D1, and the shafts 14a, 14b, and is fixed to the stop movable section 16. It may include first to fourth rotating members 14c to 14f that are rotatably connected, and a long member 14g that is rotatably connected to the first and second rotating members 14c and 14d, respectively. As a result, each of the shafts 14a and 14b rotates in conjunction with each other, so that each rotating member 14c to 14f rotates in conjunction with each other, so that each stop movable portion 16 moves in conjunction with each other in the vertical direction D3.

For example, as in the present embodiment, the stopping device 12 includes a first stopping mechanism 17 that moves the stopping movable part 16 to the stopping position when the downward running acceleration of the car 2 is equal to or higher than the set overacceleration; It may also include base parts 18, 18 connected to the car guide part 9 and the second car guide part 10, respectively. Note that the first and second shafts 14a and 14b of the transmission section 14 may be rotatably connected to the base section 18, for example, as in this embodiment.

Here, the configuration of the first stop mechanism 17 will be explained with reference to FIGS. 4 and 5. Note that the first stop mechanism 17 is also referred to as an overacceleration stop mechanism. Further, the configuration of the first stop mechanism 17 is not limited to the following configuration.

As shown in FIG. 4, the first stop mechanism 17 moves the stop movable part 16 to the stop position when the downward running acceleration of the car 2 is equal to or higher than the set overacceleration, for example, as in the present embodiment. In order to achieve this, the movable stop part 16 is provided with an overacceleration applying part 19 that applies an upward force to the movable stop part 16, and a support part 20 that supports the weight of the movable stop part 16 when the movable stop part 16 is located in the standby position. You can leave it there.

The stop movable portion 16 includes, for example, a wedge-shaped movable body portion 16a and a movable connection portion 16b that connects the movable body portion 16a and the rotating members 14c to 14f of the transmission portion 14, as in the present embodiment. You may be prepared. For example, when the stop movable part 16 is located at the stop position, the movable main body part 16a cooperates with the stop fixing part 15 to pressurize and contact the car rails 4a to 4d, so that the car 2 It may also be configured to stop at the car rails 4a to 4d.

For example, as in the present embodiment, the overacceleration applying section 19 includes a first elastic body 19a that elastically deforms in the longitudinal direction of the elongated member 14g in order to apply an upward elastic restoring force to the stop movable section 16. , a first holding member 19b fixed to the base portion 18 and holding the first end of the first elastic body 19a, and a second holding member 19b fixed to the elongated member 14g and holding the second end of the first elastic body 19a. material 19c.

Thereby, the elastic restoring force of the first elastic body 19a is transmitted to the stop movable part 16 by the transmission part 14. Since the overacceleration applying section 19 is connected to the transmitting section 14, it continues to apply upward force to the stop movable section 16. Although not particularly limited, the first elastic body 19a may be a helical spring, for example, as in this embodiment.

Note that the overacceleration applying section 19 is not the first elastic body 19a that applies an elastic restoring force, but a member that applies an upward force to the stop movable section 16 without using electric power (for example, a weight that applies gravity, etc.). ). Further, for example, the overacceleration applying section 19 may include a member (for example, a motor, an electromagnetic cylinder, etc.) that applies an upward force to the stop movable section 16 using electric power.

The support portion 20 may directly support the stop movable portion 16 from below as in the present embodiment, or may indirectly support the stop movable portion 16 by supporting the transmission portion 14, for example. It may be supported by As a result, when the stop movable part 16 is located in the standby position, the support part 20 supports the weight of the stop movable part 16, so the overacceleration applying part 19 is able to absorb the weight of a part of the stop movable part 16. Due to this, it is elastically deformed.

Therefore, the standby position is located above the balance position. Note that the balance position is a position where the weight of the stop movable part 16 balances the elastic recovery amount of the overacceleration applying part 19 when the acceleration of the car 2 is zero.

Here, the operation of the first stop mechanism 17 will be explained with reference to FIGS. 4 and 5. Note that the operation of the first stop mechanism 17 is not limited to the following operation.

As shown in FIG. 4, for example, when the acceleration of the car 2 is zero, the first elastic body 19a of the over-acceleration applying section 19 absorbs the weight of the stop movable section 16 (specifically, the weight of the transmission section 14, etc.). (including weight), it elastically deforms to contract. On the other hand, when the car 2 moves downward with acceleration, an upward inertial force is applied to the movable stop part 16 (specifically, the mass of the movable stop part 16 and the moving acceleration of the car 2 product) works.

As a result, when the apparent weight of the stop movable part 16 (the resultant force of the gravity due to the mass and the inertial force) becomes smaller than the upward elastic restoring force that the first elastic body 19a applies to the stop movable part 16. Then, the stop movable part 16 moves upward. Note that the smaller the apparent weight of the movable stop portion 16, that is, the greater the downward running acceleration of the car 2, the greater the amount of elastic recovery of the first elastic body 19a, so the position of the movable stop portion 16 is Become upward.

Therefore, when the downward running acceleration of the car 2 becomes equal to or greater than the reference acceleration, the stop movable part 16 moves upward from the standby position. As a result, for example, when the downward running acceleration of the car 2 is less than the reference acceleration, it is possible to suppress the stop movable part 16 from moving from the standby position.

Although not particularly limited, the reference acceleration may be, for example, larger than the rated acceleration of the car 2 (maximum acceleration during normal operation), and may be, for example, 10% of the gravitational acceleration. Thereby, when the car 2 is in normal operation, the stop movable part 16 can be held at the standby position. Therefore, for example, it is possible to suppress unnecessary movement of the stop movable portion 16 in the vertical direction D3.

Further, for example, when a passenger jumps inside the car 2, the downward running acceleration of the car 2 may momentarily become about 50% of the gravitational acceleration. Therefore, it is preferable that the reference acceleration is, for example, 50% of the gravitational acceleration. Thereby, for example, when a passenger jumps inside the car 2, it is possible to suppress the stop movable part 16 from moving in the vertical direction D3.

When the downward running acceleration of the car 2 exceeds the set over-acceleration, the stop movable part 16 moves upward to the stop position, as shown in FIG. As a result, the stop movable section 16 cooperates with the stop fixing section 15 to stop the car 2 on the car rails 4a to 4d.

Therefore, when the downward running acceleration of the car 2 exceeds the set overacceleration, the stopping device 12 can stop the car 2 on the car rails 4a to 4d without using an electric signal. Note that, although not particularly limited, the set overacceleration may be, for example, 70% to 90% of the gravitational acceleration.

By the way, in this embodiment, the first and second car guide parts 9 and 10 are movable with respect to the car main body part 8 by the car connection part 2a (see FIG. 3). On the other hand, as shown in FIG. 5, the base part 18 has a first connecting part 18a movably connected to the first car guide part 9 (see also FIGS. 11 and 12), for example, as in the present embodiment. ) and a second connection part 18b (see also FIG. 9) rotatably connected to the second car guide part 10.

As a result, when the first and second car guide sections 9 and 10 move relative to the car main body 8, the base section 18 moves relative to the car main body 8, so that the transmission section 14 also moves relative to the car main body 8. Move against 8. Therefore, even if the first and second car guide parts 9 and 10 move relative to the car main body 8, the position of the stop movable part 16 with respect to the stop fixed part 15 can be made appropriate.

Although not particularly limited, the first connecting portion 18a of the base portion 18, for example, as in the present embodiment, connects the connected portion 9c of the first car guide portion 9 (see also FIGS. 11 and 12) with the inner peripheral surface. It may also be a long guide hole for guiding. As a result, the first connecting portion 18a of the base portion 18 is movable with respect to the first car guide portion 9, and the second connecting portion 18b of the base portion 18 is rotatable with respect to the second car guiding portion 10. It becomes possible.

As shown in FIG. 6, the stop device 12 includes, for example, a second stop mechanism 21 that moves the stop movable part 16 to a stop position when the downward traveling speed of the car 2 is equal to or higher than a set overspeed; The vehicle may also include a third stop mechanism 30 that moves the stop movable portion 16 to the stop position when the traveling speed of No. 2 is less than or equal to the set speed. Note that the set overspeed is faster than the set speed.

Next, the configuration of the second stop mechanism 21 will be explained with reference to FIG. 7. Note that the second stop mechanism 21 is also referred to as an overspeed stop mechanism. Note that the configuration of the second stop mechanism 21 is not limited to the following configuration.

As shown in FIG. 7, the second stop mechanism 21 includes, for example, a speed governor section 22 that detects the running speed of the car 2, and a movable stop section 16 that moves upwardly so that the movable stop section 16 moves to the stop position. The overspeed accelerating unit 23 may be provided with an overspeed accelerating unit 23 that applies a force of good.

For example, as in the present embodiment, the speed governor 22 includes a governor roller 22a that is rotatably connected to the second car guide section 10, and as the governor roller 22a rotates, the speed governor 22 rotates around the revolution axis. It may include the weights 22b, 22b that revolve, a weight connection part 22c that connects the governor roller 22a and the weight 22b, and a regulating elastic part 22d that applies an elastic restoring force to the weight 22b in a direction toward the revolution axis. .

The governor roller 22a may be arranged so as to be in contact with the fourth car rail 4d, for example, as in this embodiment. As a result, the governor roller 22a rotates as the car 2 travels. Therefore, as the traveling speed of the car 2 is faster, the centrifugal force acting on the weight 22b becomes larger, so that the position of the weight 22b moves away from the revolution axis. Then, when the car 2 runs at the set overspeed, the weight 22b is located at the set position.

Note that, for example, the governor roller 22a may be configured to rotate as the car 2 travels by contacting a rail different from the car rails 4a to 4d. As described above, although not particularly limited, in the stop device 12 according to the present embodiment, the speed governor section 22 without a governor rope, that is, the speed governor section 22 of a governor rope press can be used. Further, the weight connecting portion 22c may include, for example, a speed-governing moving portion 22e that moves in the second lateral direction D2 as the weight 22b moves away from the revolution axis, as in the present embodiment.

Further, for example, as in the present embodiment, the transmission section 14 includes a first engagement section 14h fixed to the second shaft 14b in order to receive force from the overspeed acceleration section 23, and The part 23 may be configured to include a first operating part 23a that pushes the first engaging part 14h by moving from the retracted position (see FIGS. 7 and 8) to the operating position (see FIG. 9). As a result, the over-acceleration applying section 23 is separated from the transmitting section 14, so that the operation of the transmitting section 14 due to the force of the over-accelerating applying section 19 (see FIGS. 4 and 5) The movement of the stop movable part 16 due to the force of the part 19 is not inhibited by the overspeed applying part 23.

For example, as in the present embodiment, the overspeed applying section 23 includes a second elastic body 23b that applies an elastic restoring force to the first operating section 23a, and a base section in order to apply an elastic restoring force to the stop movable section 16. 18 and holds the first end of the second elastic body 23b; and a fourth holding member 23d that is fixed to the first operating section 23a and holds the second end of the second elastic body 23b. It may also have the following.

The second elastic body 23b may be elastically deformed, for example, in the second lateral direction D2, where the first operating portion 23a hits the first engaging portion 14h, as in the present embodiment. As a result, the elastic restoring force of the second elastic body 23b in the second lateral direction D2 is applied to the first operating portion 23a. Although not particularly limited, the second elastic body 23b may be a helical spring, for example, as in this embodiment.

Note that the overspeed applying section 23 is not the second elastic body 23b that applies an elastic restoring force, but a member that applies an upward force to the stop movable section 16 without using electric power (for example, a weight that applies gravity, etc.). ). Further, the overspeed applying section 23 may include a member (for example, a motor, an electromagnetic cylinder, etc.) that applies an upward force to the stop movable section 16 using electric power, for example.

For example, as in the present embodiment, the starting part 24 includes a first rotating part 25 rotatably connected to the first operating part 23a, and a first rotating part 25 that abuts the first end 25a of the first rotating part 25. a second rotating portion 27 that abuts and stops the second end portion 25b of the first rotating portion 25 in order to cooperate with the first abutting portion 26 and prevent the rotation of the first rotating portion 25; In order to prevent the rotation of the second rotation part 27, the rotation prevention part 28 that stops the second rotation part 27 may be provided.

As a result, the rotation preventing portion 28 prevents the second rotating portion 27 from rotating, and the first abutment portion 26 and the second rotating portion 27 prevent the first rotating portion 25 from rotating. The operation of 23a is blocked. On the other hand, since the first and second rotating parts 25 and 27 become rotatable when the rotation preventing part 28 releases the blocking of the second rotating part 27, the first operating part 23a It operates by the elastic restoring force of 23b.

The second rotating part 27 includes, for example, a second abutting part 27a that abuts and stops the second end 25b of the first rotating part 25, and a first abutting part 27a that abuts and stops the second end 25b of the first rotating part 25, as in the present embodiment. It may include the abutted portion 27b and a shaft portion 27c that is arranged between the second abutted portion 27a and the first abutted portion 27b and serves as an axis of rotation. For example, as in the present embodiment, each abutment part 26, 27a is connected to the end of the first rotating part 25 from a direction opposite to the direction of the elastic restoring force that the second elastic body 23b applies to the first operating part 23a. The portions 25a and 25b may be held against each other.

For example, as in this embodiment, the first abutment part 26 may be fixed to the base part 18, and the rotation prevention part 28 may be fixed to the speed regulating movement part 22e. Further, the second rotating section 27 may be rotatably connected to the base section 18.

For example, as in the present embodiment, due to the lever principle of the first and second rotating parts 25 and 27, the force applied by the second rotating part 27 to the rotation blocking part 28 is reduced by the force applied by the second elastic body 23b to the first The force may be smaller than the force applied to the operating portion 23a. Thereby, the frictional force generated between the second rotating part 27 and the rotation preventing part 28 can be reduced, so that the movement of the regulating moving part 22e can be made smooth.

Moreover, the rotation preventing portion 28 may abut and stop the first abutted portion 27b of the second rotating portion 27 from above, for example, as in the present embodiment. Thereby, since the rotation blocking part 28 does not receive the weight of the second rotating part 27, the frictional force generated between the second rotating part 27 and the rotation blocking part 28 can be further reduced. Therefore, the movement of the speed regulating moving part 22e can be made even smoother.

Further, the first abutted portion 27b may be, for example, a rolling element (for example, a roller) that can roll. Thereby, the frictional force generated between the second rotating part 27 and the rotation preventing part 28 can be efficiently reduced. Therefore, since the speed governor moving section 22e can be efficiently and smoothly moved, the speed of the car 2 can be accurately detected by the speed governor 22, for example.

Here, the operation of the second stop mechanism 21 will be explained with reference to FIGS. 7 to 9. Note that the operation of the second stop mechanism 21 is not limited to the following operation.

First, when the moving speed of the car 2 is less than the set overspeed, as shown in FIG. Rotation of 25 and 27 is prevented. As a result, the second rotating section 27 is located at the pre-activation position, and the stop movable section 16 is located at the standby position.

On the other hand, for example, when the downward traveling speed of the car 2 reaches the set overspeed and the weight 22b moves to the set position as shown in FIG. move in the second lateral direction D2 to a position where the stop is released. Therefore, the first and second rotating parts 25 and 27 can be rotated.

As a result, as shown in FIG. 9, the second elastic body 23b is restored, and the first operating portion 23a moves in the second lateral direction D2 from the retracted position to the operating position, thereby moving the first engaging portion 14h. is pressed to apply the elastic restoring force of the second elastic body 23b to the first engaging portion 14h. As the second shaft 14b rotates accordingly, the stop movable portion 16 moves to the stop position.

Therefore, the stop movable part 16 cooperates with the stop fixing part 15 to stop the car 2 on the car rails 4a to 4d. As a result, when the downward running speed of the car 2 moves at a set overspeed or higher, the car 2 can be stopped on the car rails 4a to 4d by the stopping device 12 without using an electric signal. Note that, although not particularly limited, the set overspeed may be, for example, larger than the rated speed of car 2 (maximum speed during normal operation), for example, it may be set to 110% to 120% of the rated speed of car 2. good.

Note that when the running speed of the car 2 is less than the set overspeed, even if the speed governor moving section 22e moves, the force by the overspeed applying section 23 is not applied to the stop movable section 16, so that the overacceleration does not occur. The movement of the stop movable part 16 due to the force of the force applying part 19 is not inhibited by the overspeed applying part 23. That is, the movement of the stop movable part 16 by the overacceleration applying part 19 is independent from the movement of the stop movable part 16 by the overspeed applying part 23. Thereby, for example, it is possible to suppress the traveling acceleration when the stop movable portion 16 is located at the stop position from deviation from the set excessive acceleration.

Further, when the running speed of the car 2 moves at the set overspeed, the overspeed acceleration section 23 starts applying force to the stop movable section 16, and moves the stop movable section 16 all at once to the stop position. That is, the movement of the stop movable part 16 by the over-acceleration applying part 23 is independent from the movement of the stop movable part 16 by the over-acceleration applying part 19. Thereby, for example, it is possible to suppress the traveling speed when the stop movable portion 16 is located at the stop position from deviation from the set overspeed.

Next, the configuration of the third stop mechanism 30 will be explained with reference to FIGS. 10 to 12. Note that the third stop mechanism 30 is also referred to as a normal stop mechanism, or, for example, as a stop mechanism upon landing or a stop mechanism during maintenance. Note that the configuration of the third stop mechanism 30 is not limited to the following configuration.

As shown in FIG. 10, the third stop mechanism 30 includes, for example, an operation applying part 31 that applies an upward force to the stop movable part 16 so that the stop movable part 16 moves to the stop position; 16 from the stop position to the standby position, and a blocking part 33 that prevents the operation applying part 31 from applying force to the stop movable part 16.

Further, for example, as in the present embodiment, the transmission section 14 includes a second engagement section 14i fixed to the first shaft 14a in order to receive force from the motion force application section 31. may be configured to include a second operating portion 31a that pushes the second engaging portion 14i by operating. Thereby, the motion force application section 31 is separated from the transmission section 14.

For example, as in the present embodiment, the motion applying section 31 includes a third elastic body 31b that applies an elastic restoring force to the second operating section 31a, and a base section 18 in order to apply an elastic restoring force to the stop movable section 16. A fifth holding member 31c is fixed to and holds the first end of the third elastic body 31b, and a sixth holding member 31d is fixed to the second operating portion 31a and holds the second end of the third elastic body 31b. may be provided. In addition, the 5th holding member 31c may be comprised so that the elongate 2nd operation|movement part 31a extended in the 2nd lateral direction D2 may be guided along the 2nd lateral direction D2, for example.

The third elastic body 31b may be elastically deformed, for example, in the second lateral direction D2, where the second operating portion 31a hits the second engaging portion 14i, as in the present embodiment. Thereby, the elastic restoring force of the third elastic body 31b in the second lateral direction D2 is applied to the second operating portion 31a. Although not particularly limited, the third elastic body 31b may be a helical spring, for example, as in this embodiment.

Note that the motion force applying section 31 is, for example, a member that applies an upward force to the stop movable section 16 without using electric power (for example, a weight that applies gravity), instead of the third elastic body 31b that applies an elastic restoring force. You may be prepared. Although not particularly limited, the motion applying section 31 may be configured to apply an upward force to the stop movable section 16 using at least one of elastic restoring force and gravity without using electric power, for example.

For example, as in the present embodiment, the blocking unit 33 prevents the operation applying unit 31 from applying force to the stop movable unit 16 when power is supplied, and prevents the operation force applying unit 31 from applying force to the stop movable unit 16 when power supply is stopped. The restriction may be lifted at any time. Thereby, the blocking portion 33 can be switched between a blocking state in which the second operating portion 31a is prevented from moving from the retracted position to the stop position, and a release state in which the blocking is canceled. Note that the configuration of the blocking section 33 is not particularly limited.

For example, as in the present embodiment, the blocking part 33 includes an electromagnet 33a fixed to the base part 18, a magnetic body 33b attracted by the magnetic force of the electromagnet 33a, and a magnetic body 33b fixed to the second operating part 31a. It may also include a third abutting part 33c for abutting the second abutting part 31f at the end of the third abutting part 33c. The third abutting portion 33c may be formed in a long length and may be rotatable relative to the base portion 18, for example, as in the present embodiment.

For example, as in the present embodiment, the return unit 32 returns the second operating unit 31a from the operating position (see FIG. 11) to the retracted position (see FIG. 10) when the stop movable unit 16 is located at the stop position. For this purpose, a return force applying section 32a may be provided to apply force to the second operating section 31a. Thereby, when the stop movable part 16 is located at the stop position, the second operating part 31a can be separated from the second engaging part 14i of the transmission part 14.

Note that the configuration of the return force application section 32a is not particularly limited. For example, as in the present embodiment, the return force applying section 32a includes a pulley 32b that is rotatable with respect to the base section 18, and a drive source that rotates the pulley 32b by generating (self-outputting) drive on its own (self-output). For example, it may include a motor) 32c and a transmission member (eg, belt, chain) 32d that transmits the drive of the drive source 32c to the pulley 32b. Note that the third stop portion 33c may be connected to the rotating shaft of the pulley 32b to rotate together with the pulley 32b, for example, as in the present embodiment.

For example, as in the present embodiment, the position where the second abutted part 31f of the second operating part 31a abuts the third abutment part 33c is lower than the position where the transmission member 32d is connected to the pulley 32b. It may be close to the rotation axis of 32b. Thereby, the driving force required by the driving source 32c can be reduced based on the lever principle.

Note that the third abutting portion 33c may be directly connected to the rotating shaft of the drive source 32c, for example, without going through the pulley 32b and the transmission member 32d. Further, the return force applying portion 32a connects the third abutment portion 33c and the drive source 32c such that the third abutment portion 33c rotates, for example, with a drive source (for example, a cylinder) 32c that reciprocates. It may also include a link member.

The third stop mechanism 30 may include, for example, a first position detector 34 that detects that the second operating unit 31a is in the retracted position, and a second position detector 35 that detects that the second operating unit 31a is in the operating position, as in this embodiment. The configuration of each of the position detectors 34, 35 is not particularly limited, and each of the position detectors 34, 35 may be, for example, various sensors (proximity sensors, contact sensors, photoelectric sensors).

The first position detection section 34 may detect that the second operating section 31a is located at the retracted position, for example, as in the present embodiment, by detecting the position of the third abutting section 33c. In addition, the first position detection unit 34 detects, for example, the position of a predetermined portion of the pulley 3b, the magnetic body 33b, or a predetermined portion of the second operating portion 31a, so that the second operating portion 31a is located at the retracted position. may be detected.

The second position detection section 35 may detect that the second operating section 31a is located at the operating position, for example, by detecting the position of the third abutting section 33c, as in the present embodiment. The second position detection unit 35 detects, for example, the position of a predetermined portion of the pulley 3b, the magnetic body 33b, or a predetermined portion of the second operating portion 31a, so that the second operating portion 31a is located at the operating position. may be detected.

Here, the operation of the third stop mechanism 30 will be explained with reference to FIGS. 10 to 12. Note that the operation of the third stop mechanism 30 is not limited to the following operation.

As shown in FIG. 10, since the electromagnet 33a attracts the magnetic body 33b due to the electric power being supplied to the blocking part 33, the second operating part 31a is held at the retracted position. As a result, electric power is supplied to the blocking section 33, so that the blocking section 33 prevents the motion applying section 31 from applying force to the stop movable section 16.

Then, for example, the stop instruction information is input to the input unit 6 (see FIG. 1), and the processing device 5 (see FIG. 1) acquires a stop signal, thereby stopping the car 2 at a predetermined position. The traveling speed of the vehicle is reduced. Note that the stop instruction information input to the input unit 6 is not particularly limited.

For example, the input unit 6 may be an operation panel, and the predetermined position may be a position on the floor of a landing where passengers get on and off the car 2. That is, the instruction may be a stop instruction for the car device 1a to land on the floor. Furthermore, for example, the input unit 6 may be a maintenance panel, and the predetermined position may be a desired maintenance position for performing maintenance work. In other words, it may be an instruction to stop the elevator 1 for maintenance.

Thereafter, for example, the speed detection unit 11 (see FIG. 1) detects that the traveling speed of the car 2 is equal to or lower than the set speed (for example, zero). As a result, the supply of power to the blocking section 33 is stopped, so that the blocking section 33 releases the blocking of the motion applying section 31 from applying force to the stop movable section 16 . Note that at this time, since the drive source 32c is not being driven, the pulley 32b can freely rotate.

As a result, as shown in FIG. 11, the third elastic body 31b is restored, so that the second operating section 31a pushes the second engaging section 14i by moving in the second lateral direction D2, thereby causing the third elastic body 31b to return to its original state. The elastic restoring force of the body 31b is applied to the second engaging portion 14i. Accordingly, the first shaft 14a rotates and the second operating section 31a moves to the operating position, thereby moving the stop movable section 16 to the stopping position.

Then, after the second position detecting section 35 detects the position of the second operating section 31a via the third abutment section 33c, for example, by stopping the driving of the car driving section 3 (see FIG. 1), Car 2 moves downward under its own weight. As a result, the stop movable section 16 cooperates with the stop fixing section 15 to stop the car 2 on the car rails 4a to 4d.

As a result, when the running speed of the car 2 is lower than the set speed, the operation force applying section 31 applies an upward force to the stop movable section 16 to move the car 2 to the stop position. can be stopped. Although not particularly limited, the set speed may be, for example, 10% or less of the rated speed, or may be, for example, 5% or less of the rated speed.

By the way, for example, when the supply of power to the blocking part 33 is stopped due to a power outage or the like, the supply of power to the blocking part 33 is stopped, so that the blocking part 33 is stopped and movable by the operation applying part 31. The stop movable part 16 moves to the stop position in order to release the blocking of the force applied to the stop movable part 16 and cause the operation applying part 31 to apply an upward force to the stop movable part 16 without using electric power. do. This allows the car 2 to be stopped on the car rails 4a to 4d even if the power supply is stopped due to, for example, a power outage.

On the other hand, as shown in FIG. 12, when the stop movable part 16 is located at the stop position, the return force applying part 32a applies force to the second operating part 31a via the third stop part 33c of the blocking part 33. By adding, the second operating portion 31a separates from the second engaging portion 14i of the transmission portion 14. Then, when the second operating section 31a returns from the operating position to the retracted position, power is supplied to the blocking section 33, thereby causing the second operating section 31a to move from the retracted position to the stop position. It becomes a state of inhibition that prevents things from happening.

Thereafter, after the first position detection section 34 detects the position of the second operating section 31a via the third abutting section 33c, the car 2 moves upward, for example. As a result, the movable stop portion 16 moves downward due to its own weight, so the movable stop portion 16 returns to the standby position.

Note that, for example, when the car 2 is stopped at a position on the landing floor in order for a passenger to get on or off the car 2, the second position detection section 35 detects the second operating section via the third stop section 33c. When the position of the car 31a is detected and the speed detection unit 11 detects that the car 2 has stopped (speed is zero), even if the door (not shown) of the car 2 is open, the return unit 32 The operating portion 31a may be moved to the retracted position. Thereby, for example, after the door of the car 2 is closed, the car 2 can smoothly start running.

According to such a configuration, since the movable stop portion 16 moves to the stop position when the operating portion 31a moves from the retracted position to the operating position, the movable stop portion 16 cooperates with the stop fixing portion 15 to Car 2 is stopped on car rails 4a to 4d. Thereby, the car 2 can be stopped on the car rails 4a to 4d.

Moreover, since the drive source 32c generates its own drive and applies force to the operating section 31a, the operating section 31a returns from the operating position to the retracted position. Thereby, the operating portion 31a can be returned to the retracted position by driving the drive source 32 without requiring any other driving.

[2]
Further, the elevator car device 1a of the above [1], as in the present embodiment, further includes a transmission section 14 that is connected to the stop movable section 16 and transmits force to the stop movable section 16, and the operation section ( In this embodiment, it is preferable that the second operating section 31a is separated from the transmitting section 14 and pushes the transmitting section 14 by moving from the retracted position to the operating position.

According to this configuration, the transmission section 14 that transmits force to the stop movable section 16 is separated from the operation section 31a, and the operation section 31a transmits the transmission section 14 by moving from the retracted position to the operation position. push. As a result, the stop movable portion 16 moves from the standby position to the stop position.

[3]
Further, in the elevator car apparatus 1a of [2] above, as in the present embodiment, the drive source 32c is activated when the stop movable part 16 is located at the stop position. A preferred configuration is that the operating section 31a is separated from the transmitting section 14 by returning the second operating section 31a from the operating position to the retracted position.

According to this configuration, when the stop movable part 16 is located at the stop position, the drive source 32c returns the operating part 31a from the operating position to the retracted position, so that the operating part 31a separates from the transmitting part 14. Thereby, the movable stop portion 16 can be returned to the standby position.

[4]
Further, in the elevator car device 1a according to any one of [1] to [3] above, as in the present embodiment, the operating portion (in the present embodiment, the second operating portion) 31a is moved from the retracted position to the The driving source 32c further includes a blocking section 33 that can be switched between a blocking state in which movement to the stop position is prevented and a release state in which the blocking is canceled, and the drive source 32c is configured to control the operating section via the blocking section 33. 31a, and the blocking portion 33 is preferably configured to enter the blocking state when the operating portion 31a returns from the operating position to the retracted position.

According to such a configuration, when the blocking section 33 switches from the blocking state to the releasing state, the operating section 31a moves from the retracted position to the stop position. Then, when the drive source 32c applies force to the operating section 31a via the blocking section 33, and the operating section 31a returns from the operating position to the retracted position, the blocking section 33 enters the blocking state.

[5]
Further, in the elevator car device 1a according to any one of [1] to [4] above, as in the present embodiment, the operating section (in this embodiment, the second operating section) 31a is a processing device 5. It is preferable that the car 2 is moved from the retracted position to the operating position when the car 2 acquires information on a stop instruction to stop the car 2 and the running speed of the car 2 is less than or equal to a set speed.

According to such a configuration, when the processing device 5 acquires information on a stop instruction to stop the car 2 and the traveling speed of the car 2 is equal to or lower than the set speed, the operating unit 31a changes from the retracted position to the operating position. Move to. As a result, the stop movable portion 16 moves from the standby position to the stop position.

[6]
Furthermore, as in the present embodiment, the elevator is preferably configured to include an elevator car device 1a according to any one of [1] to [5] above, and a car rail that guides the elevator car device.

According to such a configuration, the car 2 can be stopped on the car rails 4a to 4d.

[a1]
Further, the elevator car device 1a is an elevator car device 1a that travels in the vertical direction D3 by being guided by the car rails 4a to 4d, as in the present embodiment, and includes a car 2 and a car attached to the car 2. a stop device 12 that moves together with the car 2 and stops the car 2 on the car rails 4a to 4d; the stop device 12 includes a stop fixing part 15 fixed to the car 2; It is movable with respect to the stop fixing part 15 between a stop position where the car 2 is stopped on the car rails 4a to 4d in cooperation with the fixing part 15 and a standby position which is below the stop position. When the traveling speed of the car 2 is below the set speed, an upward force is applied to the stop movable part 16 in order to move the stop movable part 16 to the stop position. A preferred configuration includes a motion applying section 31.

According to such a configuration, when the traveling speed of the car 2 is equal to or lower than the set speed, the operation force applying section 31 applies an upward force to the stop movable section 16. As a result, the movable stop portion 16 moves to the stop position, so the movable stop portion 16 cooperates with the stop fixing portion 15 to stop the car 2 on the car rails 4a to 4d. Thereby, when the running speed of the car 2 is below the set speed, the car 2 can be stopped on the car rails 4a to 4d.

[a2]
Further, in the elevator car device 1a of [a1] above, as in the present embodiment, the stopping device 12 is configured such that the operation force applying section 31 applies force to the stopping movable section 16 when electric power is supplied. The operation force application section 31 applies an upward force to the stop movable section 16 without using electric power. It is preferable to add.

According to such a configuration, when electric power is supplied to the blocking section 33, the blocking section 33 prevents the operation force application section 31 from applying force to the stop movable section 16, and at the same time prevents the motion applying section 31 from applying force to the stopping movable section 16. When the supply of power is stopped, the blocking unit 33 releases the blocking. As a result, the supply of power to the blocking portion 33 is stopped, so that the car 2 can be stopped on the car rails 4a to 4d.

Furthermore, even if the supply of power to the blocking unit 33 is stopped due to a power outage, for example, the operation applying unit 31 applies an upward force to the stopping movable unit 16 without using electricity, so that the stopping unit 33 is stopped. The movable part 16 moves to the stop position. This allows the car 2 to be stopped on the car rails 4a to 4d even if the power supply is stopped due to, for example, a power outage.

[a3]
Further, in the elevator car device 1a of [a1] or [a2], as in the present embodiment, the stop device 12 releases the upward force from being applied to the stop movable portion 16 and It is preferable that the movable stop portion 16 is provided with a return portion 32 that returns the stop movable portion 16 from the stop position to the standby position.

According to such a configuration, the upward force applied to the movable stop portion 16 is released, so the movable stop portion 16 returns from the stop position to the standby position. Thereby, the stop movable part 16 can be returned to the standby position by the return part 32.

[a4]
Further, in the elevator car device 1a according to any one of [a1] to [a3] above, as in the present embodiment, the stop device 12 includes a transmission section 14 that transmits force to the stop movable section 16. , the operation force application section 31 is separated from the transmission section 14 and applies an upward force to the stop movable section 16 by pushing the transmission section 14 (in this embodiment, a second operation section) The return unit 32 applies a force to the operating unit 31a in order to separate the operating unit 31a from the transmitting unit 14 when the stop movable unit 16 is located at the stop position. It is preferable to have a configuration including a return force applying section 32a.

According to such a configuration, the transmission section 14 that transmits force to the stop movable section 16 is separated from the operation section 31a, and when the operation section 31a pushes the transmission section 14, the stop movable section 16 is given an upward force. Force is applied. As a result, the movable stop portion 16 moves to the stop position, so the car 2 stops on the car rails 4a to 4d.

On the other hand, when the stop movable part 16 is located at the stop position, the return force applying part 32a applies force to the operating part 31a, so that the operating part 31a is separated from the transmitting part 14. Thereby, the movable stop portion 16 can be returned to the standby position.

[a5]
Further, in the elevator car device 1a of any one of [a1] to [a4] above, as in the present embodiment, the stopping device 12 is configured such that the downward running speed of the car 2 is lower than the set speed. In order to move the stop movable part 16 to the stop position when the overspeed is higher than a fast set overspeed, it is preferable to include an overspeed applying part 23 that applies an upward force to the stop movable part 16.

According to such a configuration, when the downward traveling speed of the car 2 is equal to or higher than the set overspeed, the overspeed applying section 23 applies an upward force to the stop movable section 16. As a result, the movable stop portion 16 moves to the stop position, so the car 2 stops on the car rails 4a to 4d. Therefore, even when the downward traveling speed of the car 2 is equal to or higher than the set overspeed, the car 2 can be stopped on the car rails 4a to 4d.

[a6]
Further, in the elevator car device 1a according to any one of [a1] to [a5] above, as in the present embodiment, the stopping device 12 is configured to operate when the downward running acceleration of the car 2 is equal to or higher than the set over-acceleration. In order to move the stop movable part 16 to the stop position at a certain time, it is preferable to include an overacceleration applying part 19 that applies an upward force to the stop movable part 16.

According to this configuration, when the downward running acceleration of the car 2 is equal to or higher than the set overacceleration, the overacceleration applying section 19 applies an upward force to the stop movable section 16. As a result, the movable stop portion 16 moves to the stop position, so the car 2 stops on the car rails 4a to 4d. Therefore, even when the downward running acceleration of the car 2 is equal to or higher than the set overacceleration, the car 2 can be stopped on the car rails 4a to 4d.

[a7]
Further, as in the present embodiment, the elevator 1 includes an elevator car device 1a of any one of the above [a1] to [a6], and car rails 4a to 4d that guide the elevator car device 1a. This configuration is preferable.

According to such a configuration, the car 2 can be stopped on the car rails 4a to 4d when the traveling speed of the car 2 is lower than the set speed.

Note that the elevator 1 and the elevator car device 1a are not limited to the configurations of the embodiments described above, nor are they limited to the effects described above. Furthermore, it goes without saying that the elevator 1 and the elevator car device 1a may be modified in various ways without departing from the gist of the present invention. For example, it is of course possible to arbitrarily select one or more of the configurations, methods, etc. according to the various modification examples described below and adopt them as the configurations, methods, etc. according to the above-described embodiments.

(A) In the elevator car device 1a according to the above embodiment, the blocking section 33 prevents the operation applying section 31 from applying force to the stop movable section 16 when electric power is supplied, and The configuration is such that the blocking is canceled when the supply is stopped. However, the elevator car device 1a is not limited to such a configuration. For example, the blocking unit 33 prevents the operation applying unit 31 from applying force to the stop movable unit 16 when the supply of power is stopped, and releases the blocking when the power is supplied. It may be configured as follows.

(B) Furthermore, in the elevator car device 1a according to the embodiment described above, the operation force application section 31 is configured to apply upward force to the stop movable section 16 without using electric power.

(F) In the elevator car apparatus 1a according to the above embodiment, the stop movable part 16 to which the operation force applying part 31 applies an upward force is the stop movable part 16 to which the overspeed force applying part 23 applies an upward force. The configuration is the same as that of section 16. However, the elevator car device 1a is not limited to such a configuration. For example, the stop movable section 16 to which the motion force applying section 31 applies an upward force may be different from the stop movable section 16 to which the overspeed force applying section 23 applies an upward force.

(G) In the elevator car apparatus 1a according to the above embodiment, the stop movable part 16 to which the operation force applying part 31 applies an upward force is the stop movable part 16 to which the overacceleration applying part 19 applies an upward force. The configuration is the same as that of section 16. However, the elevator car device 1a is not limited to such a configuration. For example, the stop movable part 16 to which the operation force applying part 31 applies an upward force may be different from the stop movable part 16 to which the overacceleration applying part 19 applies an upward force.

(H) Furthermore, in the elevator car device 1a according to the above embodiment, the return section 32 (drive source 32c) is configured to indirectly apply force to the second operating section 31a via the blocking section 33. be. However, the elevator car device 1a is not limited to such a configuration. For example, the return unit 32 (drive source 32c) may be configured to directly apply force to the second operating unit 31a.

(I) Furthermore, in the elevator car device 1a, as shown in FIGS. 13 and 14, the third stop mechanism 30 is configured to include a regulating portion 36 that regulates the rotation of the third stop portion 33c. But that's fine. Note that, although not particularly limited, the regulating portion 36 may be fixed to the base portion 18, for example. According to such a configuration, as shown in FIG. 14, when the blocking part 33 is in the released state, the third abutting part 33c hits the regulating part 36, thereby preventing the third abutting part 33c from rotating too much. can be regulated.

(J) For example, the execution order of each process such as the operation, procedure, step, and stage in the system, method, program, and device shown in the claims, specification, and drawings is the output of the previous process. They can be implemented in any order as long as they are not used in subsequent processing. For example, even if "first", "next", etc. are used in the explanation for convenience, this does not mean that execution in this order is essential.
