For example, the guide mechanism 4 is guided by the guide rails 8 and 9 extending in the vertical direction D3 and fixed to the hoistway, as in the present embodiment, and is guided by the guide rails 8 and 9 to move the car 2 and the motor movable body 7. It may be provided with a guide body 10 to be connected. Although not particularly limited, in the guide mechanism 4, for example, as in the present embodiment, the guide bodies 10, 10 may be provided as a pair apart in the vertical direction D3, similarly to the motor movable body 7. .

The elevator 1 includes an elevator fixed body 1a fixed to the hoistway and an elevator movable body 1b movable in the vertical direction D3 with respect to the elevator fixed body 1a. In this embodiment, the motor fixed body 6 and the guide rails 8 and 9 constitute the elevator fixed body 1a, and the car 2, the motor movable body 7 and the guide body 10 constitute the elevator movable body 1b.

A part 13 may be provided. The motor fixing body 6 may include, for example, the coil 14 that applies an electromagnetic force in the vertical direction D3 to the magnets 11 and 12 and the coil support portion 15 that supports the coil 14, as in the present embodiment.

The coils 14 are arranged, for example, along the vertical direction D3 and the first horizontal direction D1. On the other hand, the magnets 11 and 12 may be arranged along the vertical direction D3 and the first horizontal direction D1, and may be arranged so as to face the coil 14 in the second horizontal direction D2.

A configuration in which they are arranged in parallel along the direction D3 may also be used. Thereby, the magnets 11 and 12 are arranged along the vertical direction D3 and the first horizontal direction D1.

The coil support portion 15 may support, for example, each end of the coil 14 in the first lateral direction D1. The motor fixing body 6 may include an inverter (not shown) inside the coil support portion 15 for controlling the current in the coil 14, for example. Control device 5 (FIG. 1) controls the magnitude and direction of the current in coil 14 via an inverter, thereby controlling the magnitude and direction of the electromagnetic force applied to magnets 11 and 12 by coil 14. may

As a result, the electromagnetic force is applied to both sides of the coil 14 in the second horizontal direction D2, so that the electromagnetic force can be efficiently applied from the coil 14 to the magnets 11 and 12 .

For example, the guide body 10 may include the magnet guides 16 and 17 guided by the guide rails 8 and 9 and the guide main body 18 fixing the magnet guides 16 and 17 as in this embodiment. Thereby, the positions of the magnet guides 16 and 17 with respect to the magnets 11 and 12 are fixed. Therefore, by guiding the magnet guides 16 and 17 to the guide rails 8 and 9, it is possible to suppress a change in the distance between the magnets 11 and 12 and the coil 14. FIG.

Although not particularly limited, for example, as in this embodiment, the guide rails 8 and 9 comprise a first guide rail 8 and a second guide rail 9 that are separated in the first lateral direction D1, and the magnet guides 16 and 17 are: It is preferable to have a first magnet guide 16 guided by the first guide rail 8 and a second magnet guide 17 guided by the second guide rail 9 .

As a result, the first guide rail 8 and the first magnet guide 16 and the second guide rail 9 and the second magnet guide 17 are separated from each other in the first lateral direction D1. Swinging about the direction D3 can be suppressed. Although not particularly limited, in the guide body 10, for example, a pair of the first magnet guides 16 may be provided separately in the vertical direction D3 as in the present embodiment, or the second magnet guides 17 may be provided separately. may be provided as a pair apart in the vertical direction D3.

Although not particularly limited, the first magnet guide 16 and the second magnet guide 17 are preferably arranged between the car 2 and the coil 14 in the second lateral direction D2.

As a result, the magnet guides 16 and 17 and the guide rails 8 and 9 can be arranged closer to the car 2 . Therefore, for example, since the magnet guides 16 and 17 can be inspected from the car 2 side, the magnet guides 16 and 17 can be easily inspected.

Further, for example, when there is a deviation in operation between the linear motors 3, 3 on both sides of the car 2, the motor movable bodies 7, 7 (that is, the magnets 11, 12, 11, 12) on both sides of the car 2 move vertically. A difference occurs in the position in the direction D3. On the other hand, since the magnets 11 and 12 are arranged outside the magnet guides 16 and 17 in the second horizontal direction D2, the inclination of the car 2 can be reduced. As a result, for example, it is possible to prevent the passenger in the car room 21 from becoming uncomfortable.

As shown in FIGS. 5 and 6, the elevator fixed body 1a includes rail fixing portions 19 fixed to the motor fixed body 6 and the guide rails 8 and 9, respectively, as in the present embodiment. good too. Although not particularly limited, the rail fixing portion 19 may be fixed to the motor fixing body 6 and the guide rails 8 and 9 by, for example, bolts and nuts.

The rail fixing portion 19 includes, for example, the first rail fixing portion 19 fixed to the motor fixing body 6 and the first guide rail 8, the motor fixing body 6 and the second guide rail 8, as in the present embodiment. A second rail fixing portion 19 fixed to each rail 9 may be provided. A plurality of first and second rail fixing portions 19 may be provided, for example, so as to be aligned in the vertical direction D3.

Further, for example, the guide rails 8 and 9 are fixed to the hoistway by fixing means, and the motor fixing body 6 is fixed to the guide rails 8 and 9 by the rail fixing portion 19, so that the motor fixing body 6 can be lifted and lowered. It may be fixed to the road. Thereby, the coil 14 can be arranged at a desired position with respect to the guide rails 8 and 9 . Therefore, the position of the coil 14 with respect to the guide rails 8 and 9 can be made constant over the vertical direction D3.

Further, for example, the rail fixing portion 19 may be provided with a rail positioning portion 19a that contacts the guide rails 8, 9 in the second lateral direction D2 in order to position the guide rails 8, 9 as in the present embodiment. good. Further, the rail fixing portion 19 may include, for example, a coil positioning portion 19b that contacts the motor fixing body 6 in the second lateral direction D2 in order to position the coil 14 as in the present embodiment.

Thereby, the coil 14 can be arranged at a desired position with respect to the guide rails 8 and 9 in the second lateral direction D2. Therefore, the position of the coil 14 in the second lateral direction D2 with respect to the guide rails 8 and 9 can be reliably kept constant over the vertical direction D3. Although not particularly limited, each of the positioning portions 19a and 19b may, for example, be configured by a step as in the present embodiment. may be configured.

Further, the rail positioning portion 19a is, for example, as in the present embodiment, one of the ends 8b, 8c, 9b, 9c of the guide rails 8, 9 in the second lateral direction D2, which is closer to the motor fixing body 6. It may contact the portions 8b and 9b. Further, the coil positioning portion 19b is, for example, as in the present embodiment, the guide rail 8 between the ends 6a and 6b of the motor fixing body 6 (specifically, the coil support portion 15) in the second lateral direction D2. , 9 may be in contact with the end 6a. Thereby, the dimension of the rail fixing portion 19 in the second lateral direction D2 can be reduced.

As shown in FIGS. 7 to 9, for example, the magnet guides 16, 17 are provided with a pair of first rollers 16a, 16a, 17a, 17a and one second roller 16b, 17b as in this embodiment. , the guide rails 8, 9 may comprise rail plates 8a, 9a for guiding the rollers 16a, 16b, 17a, 17b.

The rail plates 8a, 9a are arranged along the vertical direction D3 and the first horizontal direction D1, and the pair of first rollers 16a, 16a, 17a, 17a are arranged in the second horizontal direction D2, and are arranged along the second horizontal direction D2. It may be in contact with the rail plates 8a and 9a with the rail plates 8a and 9a interposed therebetween in the direction D2. Thereby, it is possible to suppress the magnets 11 and 12 from being displaced in the second lateral direction D2 with respect to the coil 14.

Also, the second roller 16b of the first magnet guide 16 and the second roller 17b of the second magnet guide 17 may contact the ends of the rail plates 8a and 9a in the first lateral direction D1. As a result, the guide body 10 can be restrained from being displaced in the first lateral direction D1 with respect to the guide rails 8 and 9, so that the magnets 11 and 12 are displaced in the first lateral direction D1 with respect to the coil 14. can be suppressed

For example, as in the present embodiment, the guide main body 18 includes guide fixing portions 20, 20 for fixing the first magnet guide 16 and the second magnet guide 17 at respective ends in the first lateral direction D1. good too. For example, the guide fixing portion 20 includes roller support portions 20a, 20a that support the rollers 16a, 16b, 17a, 17b, and roller support portions 20a that extend in the first lateral direction D1, and roller support portions 20a at respective ends in the first lateral direction D1. , 20a may be provided.

The roller support portion 20a fixes the positions of the rotation shafts of the rollers 16a, 16b, 17a, and 17b to rotatably support the rollers 16a, 16b, 17a, and 17b. 7 and has rigidity so as not to be elastically deformed. Thereby, the positions of the rotation shafts of the rollers 16a, 16b, 17a, 17b with respect to the magnets 11, 12, that is, the positions of the magnet guides 16, 17 with respect to the magnets 11, 12 are unchanged and fixed.

Although not particularly limited, the dimension W1 of the guide fixing portion 20 in the first lateral direction D1 is preferably smaller than the dimension W2 of the car 2 in the first lateral direction D1 (see FIG. 2). Thereby, the length of the guide fixing|fixed part 20 can be shortened.

Therefore, for example, the weight of the guide fixing part 20 can be reduced, and for example, the area occupied by the guide fixing part 20 in the up-down direction D3 view in the hoistway can be reduced. Also, for example, when the door (not shown) of the car 2 moves in the second lateral direction D2, it is possible to prevent the door from hitting the guide fixing portion 20 .

As shown in FIG. 10, the car 2 includes, for example, a car room 21 in which people ride, a car frame 22 connected to the car room 21, and a car room 21 and car frame 22 connected to each other, as in the present embodiment. A first connecting portion (also referred to as a “car connecting portion”) 23 may be provided. The car frame 22 is, for example, a rectangular support frame that is fixed to the tops of the vertical frames 22a, 22a, the horizontal frames 22b, 22b, and the lower horizontal frame 22b and supports the car chamber 21, as in the present embodiment. 22c.

The first connecting portion 23 may connect the cage 21 and the support frame 22c, for example. Specifically, for example, the upper portion of the first connection portion 23 is connected (directly connected) to the lower portion of the car chamber 21, and the lower portion of the first connection portion 23 is connected to the upper portion of the support frame 22c. may be configured. Thus, the first connecting portion 23 connects the car chamber 21 and the car frame 22 in the vertical direction D3, and the car frame 22 supports the car chamber 21 from below.

The first connecting portion 23 may connect the car chamber 21 and the car frame 22 so that the car chamber 21 can move in the lateral directions D1 and D2 with respect to the car frame 22, for example. Specifically, the first connecting portion 23 may be an elastic body that is elastically deformable in the horizontal directions D1 and D2 and the vertical direction D3. As a result, transmission of the vibration of the car frame 22 to the car chamber 21 can be suppressed by the first connecting portion 23 .

Although not particularly limited, the first connecting portion 23 may be made of, for example, rubber (for example, laminated rubber), and may be an elastic body whose elastic modulus in the lateral directions D1 and D2 is smaller than the elastic modulus in the vertical direction D3. Preferably. In addition, since the first connection portion 23 is elastically deformed in the vertical direction D3 by the load in the car chamber 21, the car 2 is deformed by the load in the car chamber 21 based on the amount of elastic deformation of the first connection portion 23 in the vertical direction D3. A load detection unit (not shown) for detecting the may be provided.

By the way, as shown in FIGS. 10 to 14, the motor movable body 7 and the magnet guides 16 and 17 are fixed to the guide body 18 having rigidity so as not to be elastically deformed. The positions of the rollers 16a, 16b, 17a, 17b of the magnet guides 16, 17 are fixed. As a result, the vibrations of the rollers 16a, 16b, 17a, and 17b are transmitted to the guide body 18 as they are.

Therefore, the elevator movable body 1b, for example, as in the present embodiment, has a second connecting portion (" It is preferable to have a movable body connecting portion) 24 . That is, it is preferable that the elevator movable body 1b includes a first structure 1c, a second structure 1d, and a second connecting portion 24. As shown in FIG.

11 to 13 show the motor movable body 7, the guide body 10 and the magnet guides 16 and 17 on the upper side, and FIG. 14 shows the motor movable body 7, the guide body 10 and the magnet guide 16 on the lower side. , 17 are shown. 11 to 14, only the horizontal frame 22b of the car 2 is shown.

The second connection part 24 connects the first structure 1c and the second structure 1d so that the first structure 1c is movable in the lateral directions D1 and D2 with respect to the second structure 1d, for example. is preferred. As a result, the second connecting portion 24 can suppress transmission of the vibration of the rollers 16a, 16b, 17a, 17b of the magnet guides 16, 17 to the car chamber 21 of the car 2. As shown in FIG.

For example, as in the present embodiment, the second connecting portion 24 may connect the car 2 and the guide body 10 so that the car 2 can move in the lateral directions D1 and D2 with respect to the guide body 10. . Specifically, the upper portion of the second connection portion 24 is connected to the lower portion of the horizontal frame 22b of the car frame 22, and the lower portion of the second connection portion 24 is connected to the upper portion of the connection frame 25 of the guide body portion 18. , may be used. Thus, the second connection portion 24 connects the car frame 22 of the car 2 and the guide body portion 18 of the guide body 10 in the vertical direction D3, and the guide body 10 supports the car 2 from below.

Therefore, in this embodiment, the first structure 1c is composed of the cage 2, and the second structure 1d is composed of the motor movable body 7, the guide body 10 and the magnet guides 16,17. Accordingly, since the cage frame 22 is included in the first structure 1c, the weight of the second structure 1d can be reduced. Therefore, when the magnet guides 16 and 17 vibrate, it is possible to suppress an increase in the inertial force acting on the second structure 1d.

The second connecting portion 24 may be, for example, an elastic body that is elastically deformable in the horizontal directions D1 and D2 and the vertical direction D3. Although not particularly limited, the second connecting portion 24 may be made of, for example, rubber (for example, laminated rubber), and may be an elastic body whose elastic modulus in the lateral directions D1 and D2 is smaller than the elastic modulus in the vertical direction D3. Preferably.

While the first connecting portion 23 supports the car chamber 21 , the second connecting portion 24 supports the entire car 2 . Therefore, although not particularly limited, it is preferable that the modulus of elasticity of the second connecting portion 24 in the lateral directions D1 and D2 is higher than the modulus of elasticity of the first connecting portion 23 in the lateral directions D1 and D2. As a result, the first structure 1c including the car frame 22 can be prevented from being displaced excessively in the lateral directions D1 and D2 with respect to the second structure 1d including the guide member .

In contrast to the fact that the first structure 1c is movable in the lateral directions D1 and D2 with respect to the second structure 1d by means of the second connecting portion 24, the elevator movable body 1b is, for example, as in the present embodiment. Preferably, the first structure 1c is provided with a vibration suppressor 26 that suppresses the vibration of the first structure 1c in the lateral directions D1 and D2 with respect to the second structure 1d.

The vibration suppression part 26 may, for example, connect the car frame 22 of the first structure 1c and the guide body 10 of the second structure 1d. For example, as in the present embodiment, the vibration suppressing portion 26 includes a car rail 27 extending in the vertical direction D3, a car guide 28 guided by the car rail 27, and a guide support portion 29 supporting the car guide 28. , and an elastic portion 30 having elasticity.

The car rail 27 may be connected to the guide body 10 of the second structure 1d, for example. For example, in the present embodiment, the car rail 27 is immovably fixed to the guide main body portion 18 of the guide body 10 (the guide fixing frame 20b in FIGS. 11 to 13 and the connection frame 25 in FIG. 14). It is

The car guide 28 may, for example, comprise a plurality of rollers 28a, 28b. For example, the guide support portion 29 is immovably fixed to the horizontal frame 22 b of the car frame 22 , and the guide support portion 29 is arranged such that the positions of the rotation shafts of the rollers 28 a and 28 b are set in the car frame 22 so that the positions of the rotation shafts of the rollers 28 a and 28 b are set relative to the car frame 22 The rollers 28a, 28b may be rotatably connected so that they are movable in the lateral directions D1, D2.

The elastic portion 30 may be elastically deformed in the lateral directions D1 and D2 as the rollers 28a and 28b are displaced in the lateral directions D1 and D2 with respect to the car frame 22, for example. Although not particularly limited, the elastic portion 30 may be, for example, a spiral spring that is elastically deformable in the lateral directions D1 and D2.

Although not particularly limited, the plurality of rollers 28a and 28b of the car guide 28 may be, for example, third rollers 28a and 28a movable with respect to the car frame 22 in the first lateral direction D1, and third rollers 28a and 28a with respect to the car frame 22. A fourth roller 28b movable in two lateral directions D2 may be provided. As a result, the elastic restoring force of the elastic portion 30 in the first lateral direction D1 is applied to the car rail 27 via the third rollers 28a, 28a, and the elastic portion 30 is applied to the car rail 27 via the fourth roller 28b. An elastic restoring force is applied in the second lateral direction D2.

Therefore, since the elastic portion 30 applies an elastic restoring force to the rollers 28a and 28b toward the car rail 27, an elastic restoring force for restoring the displacement of the rollers 28a and 28b is applied to the rollers 28a and 28b. As a result, it is possible to suppress the first structure 1c from vibrating in the lateral directions D1 and D2 with respect to the second structure 1d.

Further, for example, when the second connection portion 24 is elastically deformed in the vertical direction D3 and the car frame 22 is displaced in the vertical direction D3 with respect to the guide body 10, the rollers 28a and 28b of the car guide 28 move toward the car rails 27. be guided by Thus, when the first structure 1c is displaced in the vertical direction D3 with respect to the second structure 1d, the first structure 1c is displaced in the lateral directions D1 and D2 with respect to the second structure 1d. can be suppressed.

As described above, as in the present embodiment, the elevator 1 includes a car 2 having a car room 21 for people to ride in, magnets 11 and 12 connected to the car 2, and electromagnetic waves in the vertical direction D3 to the magnets 11 and 12. force-applying coils 14, guide rails 8, 9 extending along the vertical direction D3; fixed positions with respect to the magnets 11, 12 and guided by the guide rails 8, 9; The magnet guides 16, 17 and the first structure 1c including the cage 21 are movable in the lateral directions D1, D2 with respect to the second structure 1d including the magnet guides 16, 17. A configuration in which a connecting portion (in this embodiment, a second connecting portion) 24 that connects the first structure 1c and the second structure 1d is provided is preferable.

With such a configuration, the positions of the magnet guides 16, 17 with respect to the magnets 11, 12 are fixed. As a result, the magnet guides 16 and 17 are guided by the guide rails 8 and 9, so that the distance between the magnets 11 and 12 and the coil 14 can be suppressed from changing.

Moreover, the connection portion 24 connects the first structure 1c and the second structure 1d, so that the first structure 1c including the car chamber 21 is connected to the second structure 1d including the magnet guides 16 and 17. Therefore, it becomes possible to displace in the lateral directions D1 and D2.
