[0009] Hereinafter, embodiments will be described with reference to the drawings. Embodiment 1. FIG. 1 is a schematic configuration diagram showing an elevator according to Embodiment 1. In FIG. 1, a machine room 12 is provided above a hoistway 11. A hoisting machine 13 and a deflector sheave 14 are provided in the machine room 12.

[0010] The hoisting machine 13 includes a hoisting machine main body 15 and a driving sheave 16. The hoisting machine main body 15 includes a hoisting machine motor (not shown) and a hoisting machine brake (not shown). The hoisting machine motor rotates the driving sheave 16. The hoisting machine brake maintains the stationary state of the driving sheave 16. Also, the hoisting machine brake brakes the rotation of the driving sheave 16.

[0011] A suspension body 17 is wound around a drive sheave 16 and a deflector sheave 14. A plurality of ropes or a plurality of belts are used as the suspension body 17.

[0012] A car 18 serving as an elevating body is connected to a first end portion of the suspension body 17. A counterweight 19 serving as an elevating body is connected to a second end portion of the suspension body 17.

[0013] The car 18 and the counterweight 19 are suspended within a hoistway 11 by the suspension body 17. Further, the car 18 and the counterweight 19 are moved up and down within the hoistway 11 by rotating the drive sheave 16.

[0014] A plurality of guide rails are installed within the hoistway 11. The plurality of guide rails include a pair of car guide rails 20 and a pair of counterweight guide rails 21. In FIG. 1, only the car guide rail 20 on one side among the pair of car guide rails 20 and the counterweight guide rail 21 on one side among the pair of counterweight guide rails 21 are shown.

[0015] The pair of car guide rails 20 guide the ascending and descending of the car 18. The pair of counterweight guide rails 21 guide the ascending and descending of the counterweight 19.

[0016] The car 18 includes a car frame 22 and a car compartment 23. The suspension body 17 is connected to the car frame 22. The car compartment 23 is supported by the car frame 22.

[0017] FIG. 2 is a perspective view showing the rail position adjusting apparatus according to Embodiment 1. In FIG. 2, each of the plurality of guide rails is configured by joining a plurality of rail members 24 in the vertical direction, or is configured by a single rail member 24.

[0018] The rail position adjusting apparatus 30 of Embodiment 1 is used for adjusting the position of the rail member 24 in installation work or modification work of an elevator.

[0019] When installing or renovating an elevator, if multiple guide rails are to be installed within the hoistway 11, multiple reference wires (not shown) are stretched vertically within the hoistway 11 to serve as positioning references for the multiple guide rails. For example, piano wire can be used as each reference wire.

[0020] The rail position adjustment device 30 adjusts the position of the rail member 24, i.e., aligns it, based on the positions of multiple reference wires.

[0021] Fastener plates 60 are pre-installed inside the elevator shaft 11. The fastener plates 60 are fixed to the building side.

[0022] The rail position adjustment device 30 is attached to the fastener plate 60. The rail position adjustment device 30 also includes a base 31 and a rail moving device 32.

[0023] The base 31 has a pair of leg members 33 and a support plate 34. The pair of leg members 33 are detachably attached to the fastener plate 60 by a pair of gripping devices 61. The pair of gripping devices 61 grip the pair of leg members 33 and the fastener plate 60. For example, a C-clamp is used as each gripping device 61. The support plate 34 is fixed to the upper part of the pair of leg members 33.

[0024] The rail moving device 32 is supported by the base 31. The rail moving device 32 also moves the rail body 26 horizontally relative to the base 31. The rail body 26 has rail members 24 and rail brackets 25.

[0025] The rail bracket 25 is pre-attached to the back of the rail member 24 using multiple rail clips (not shown). After the position of the rail member 24 is adjusted, the rail bracket 25 is fixed to the fastener plate 60 by welding or the like.

[0026] The rail moving device 32 has a pair of gripping arms 35 and an arm drive mechanism 36. The pair of gripping arms 35 grip the rail body 26. In this example, the pair of gripping arms 35 grip the rail member 24.

[0027] The arm drive mechanism 36 drives the pair of gripping arms 35 based on a position correction signal. As a result, the arm drive mechanism 36 moves the rail body 26, which is gripped by the pair of gripping arms 35, in at least one of the following directions: forward / backward, left / right, and rotational, as shown in Figure 3.

[0028] The position correction signal is a command signal for correcting the position of the rail member 24 relative to multiple reference wires to the correct installation position. The position correction signal also indicates the amount of deviation of the rail member 24 from the correct installation position, that is, the amount of movement of the rail member 24 to the correct installation position.

[0029] The arm drive mechanism 36 includes a first front-rear drive unit 37, a second front-rear drive unit 38, a movable plate 39, a first left-right drive unit 40, a second left-right drive unit 41, a first front-rear motor 42, a second front-rear motor 43, a first left-right motor 44, and a second left-right motor 45.

[0030] The first front / rear drive unit 37, the second front / rear drive unit 38, the first front / rear direction motor 42, and the second front / rear direction motor 43 are mounted on the support plate 34. One end of the movable plate 39 in the width direction is rotatably connected to the first front / rear drive unit 37. The other end of the movable plate 39 in the width direction is rotatably connected to the second front / rear drive unit 38.

[0031] The first forward / reverse motor 42 is connected to the first forward / reverse drive unit 37. The second forward / reverse motor 43 is connected to the second forward / reverse drive unit 38.

[0032] The first left-right drive unit 40, the second left-right drive unit 41, the first left-right motor 44, and the second left-right motor 45 are mounted on the movable plate 39. The first left-right motor 44 is connected to the first left-right drive unit 40. The second left-right motor 45 is connected to the second left-right drive unit 41.

[0033] The pair of gripping arms 35 move independently of each other in the left-right direction of the rail member 24 via the first left-right drive unit 40 and the second left-right drive unit 41, respectively, by driving the first left-right motor 44 and the second left-right motor 45. The left-right direction of the rail member 24 is the up-down direction in Figure 3.

[0034] Furthermore, while the rail body 26 is gripped by the pair of gripping arms 35, the rail body 26 can be moved in the left-right direction of the rail member 24 by driving the first left-right motor 44 and the second left-right motor 45.

[0035] The movable plate 39 moves in the front-rear direction of the rail member 24 by driving the first front-rear motor 42 and the second front-rear motor 43. The front-rear direction of the rail member 24 is the left-right direction in Figure 3.

[0036] Furthermore, while the rail body 26 is gripped by the pair of gripping arms 35, the rail body 26 can be moved in the front-rear direction of the rail member 24 by driving the first front-rear motor 42 and the second front-rear motor 43.

[0037] Furthermore, while the rail body 26 is gripped by the pair of gripping arms 35, the rail body 26 can be moved in the rotational direction by driving the first forward / backward motor 42 and the second forward / backward motor 43 by different amounts of rotation relative to each other.

[0038] For each of the first front / rear drive unit 37, the second front / rear drive unit 38, the first left / right drive unit 40, and the second left / right drive unit 41, for example, a mechanism using a ball screw, that is, a mechanism that converts rotational motion into linear motion, can be used.

[0039] Figure 4 is a block diagram showing the main parts of the arm drive mechanism 36 in Figure 3. Although not shown in Figure 3, the arm drive mechanism 36 further includes a motor control device 46. The motor control device 46 receives a position correction signal from a displacement detection device 47 or a correction signal input device 48.

[0040] The motor control device 46 individually controls the first forward / backward motor 42, the second forward / backward motor 43, the first left / right motor 44, and the second left / right motor 45 based on position correction signals. The functions of the motor control device 46 are implemented, for example, by a microcontroller.

[0041] The displacement detection device 47 detects the amount of horizontal displacement of the rail member 24 from multiple reference wires. For example, the displacement detection device 47 may be a combination of multiple cameras and an image processing device. In this case, the multiple cameras are installed on the rail body 26. The image processing device detects the displacement based on images captured by the multiple cameras.

[0042] If the position correction signal is directly input from the displacement detection device 47 to the motor control device 46, the correction signal input device 48 may be omitted.

[0043] If the position correction signal is not directly input from the displacement detection device 47 to the motor control device 46, the operator refers to the displacement detected by the displacement detection device 47 and inputs the position correction signal from the correction signal input device 48 to the motor control device 46.

[0044] In this rail position adjustment device 30, the base 31 is detachably attached to the fastener plate 60. The rail moving device 32 is supported by the base 31 and moves the rail body 26 horizontally relative to the base 31. The rail moving device 32 has a pair of gripping arms 35 and an arm drive mechanism 36.

[0045] A pair of gripping arms 35 grip the rail body 26. The arm drive mechanism 36 moves the rail body 26 by driving the pair of gripping arms 35 based on a position correction signal.

[0046] Therefore, the entire rail position adjustment device 30 can be made smaller, making it easier to install the rail position adjustment device 30 inside the elevator shaft 11.

[0047] Furthermore, the base 31 is attached to the fastener plate 60 by a pair of gripping devices 61. This makes it easy to install the rail position adjustment device 30 on the fastener plate 60 and to adjust the installation position of the rail position adjustment device 30 relative to the fastener plate 60. In addition, there is no need to be particular about the installation precision of the fastener plate 60, and the rail position adjustment device 30 can be installed at any position on the fastener plate 60.

[0048] Embodiment 2. Next, Figure 5 is a perspective view showing the rail position adjustment device 30 according to Embodiment 2. Figure 6 is a perspective view showing the main part of Figure 5. In Figure 6, the movable plate 39 is omitted.

[0049] In Embodiment 2, the fastener plate 60 is provided with a pair of elongated plate holes 60a. Each leg member 33 is provided with a pair of elongated base holes 33a that are perpendicular to the corresponding elongated plate holes 60a.

[0050] In this example, each plate slot 60a is provided so as to be aligned with the front-to-back direction of the rail member 24. Additionally, each base slot 33a is provided so as to be aligned with the left-to-right direction of the rail member 24.

[0051] The base 31 is attached to the fastener plate 60 by multiple fasteners 62. In Figure 5, the multiple fasteners 62 are omitted. Each fastener 62 is, for example, a combination of a bolt and a nut.

[0052] A corresponding fastener 62 is passed through each elongated hole 33a of the base and each elongated hole 60a of the plate.

[0053] Other configurations in Embodiment 2 are the same as those in Embodiment 1.

[0054] This configuration also provides the same effects as in Embodiment 1. Furthermore, it allows for more secure fixing of the base 31 to the fastener plate 60 while allowing for arbitrary adjustment of the position of the base 31 relative to the fastener plate 60.

[0055] Embodiment 3. Next, Figure 7 is a perspective view showing the rail position adjustment device 30 according to Embodiment 3. Figure 8 is a plan view showing the rail position adjustment device 30 of Figure 7.

[0056] In Embodiment 3, a pair of protrusions 34a are provided on the support plate 34. The rail body 26 is positioned between the pair of protrusions 34a. Each protrusion 34a is provided with a marker 34b that indicates the correct position of the rail body 26 relative to the base 31. Each marker 34b is, for example, a marking line.

[0057] Other configurations in Embodiment 3 are the same as those in Embodiment 1.

[0058] This configuration also provides the same effects as in Embodiment 1. Furthermore, the base 31 is attached to the fastener plate 60 with the back of the rail member 24 aligned with each mark 34b. This makes it easy to adjust the positional relationship between the rail position adjustment device 30 and the rail body 26 to the correct position before adjustment.

[0059] In Embodiment 3, each mark 34b is not limited to a scribed line.

[0060] Furthermore, in Embodiment 3, the location on the rail body 26 that aligns with each mark 34b is not limited to the back surface of the rail member 24, but may be, for example, the rail bracket 25.

[0061] Furthermore, the support plate 34 of Embodiment 2 may be provided with a mark 34b similar to that of Embodiment 3.

[0062] Embodiment 4. Next, Figure 9 is a perspective view showing the rail position adjustment device 30 according to Embodiment 4. The rail moving device 32 of Embodiment 4 further includes a first detector 51 and a second detector 52.

[0063] The first detector 51 and the second detector 52 are installed on the movable plate 39. The first detector 51 and the second detector 52 also detect whether the rail member 24 is in the correct position relative to the rail moving device 32.

[0064] Figure 10 is a schematic plan view showing the first detector 51 and the second detector 52 of Figure 9. The first detector 51 has a first sensor 51a and a second sensor 51b. The second detector 52 has a third sensor 52a and a fourth sensor 52b.

[0065] For example, sensing sensors are used as the first sensor 51a, second sensor 51b, third sensor 52a, and fourth sensor 52b. The sensing sensors detect whether or not there is an object in front of them.

[0066] In the example shown in Figure 10, when the second sensor 51b and the third sensor 52a detect the rail member 24, and the first sensor 51a and the fourth sensor 52b do not detect the rail member 24, it is detected that the rail member 24 is in the correct left-right position.

[0067] Furthermore, when the first sensor 51a and the second sensor 51b detect the rail member 24, and the third sensor 52a and the fourth sensor 52b do not detect the rail member 24, it is detected that the rail member 24 is located to the right of its proper position in Figure 10.

[0068] Furthermore, when the third sensor 52a and the fourth sensor 52b detect the rail member 24, and the first sensor 51a and the second sensor 51b do not detect the rail member 24, it is detected that the rail member 24 is located to the left of the correct position in Figure 10.

[0069] Figure 11 is a block diagram showing the main parts of the rail moving device 32 of Embodiment 4. Although omitted in Figure 9, the rail moving device 32 further includes a detector control device 53. The detector control device 53 has a position determination unit 53a and a notification unit 53b as functional blocks.

[0070] The position determination unit 53a determines whether the rail member 24 is in the correct position relative to the rail moving device 32 based on signals from the first sensor 51a, the second sensor 51b, the third sensor 52a, and the fourth sensor 52b.

[0071] The notification unit 53b notifies the worker of the determination result made by the position determination unit 53a. The notification unit 53b also notifies the worker that the rail member 24 is determined to be in the correct position by, for example, turning on an LED light or sounding a buzzer.

[0072] Each function of the detector control device 53 is implemented, for example, by a microcontroller. Other configurations in Embodiment 4 are the same as in Embodiment 1.

[0073] This configuration also provides the same effects as in Embodiment 1. Furthermore, there is no need to be particular about the installation precision of the fastener plate 60, and the positional relationship between the rail position adjustment device 30 and the rail member 24 can be easily adjusted to the appropriate position.

[0074] In the fourth embodiment, the first detector 51 and the second detector 52 may each be detectors having distance sensors that detect the distance to the rail body 26.

[0075] Furthermore, in Embodiment 4, the number of detectors is not limited to two.

[0076] Embodiment 5. Next, Figure 12 is a plan view showing the rail position adjustment device 30 according to Embodiment 5. Each of the pair of gripping arms 35 in Embodiment 5 is provided with a contact surface 35a. The rail body 26 is placed against each contact surface 35a. In this example, the back surface of the rail member 24 is placed against each contact surface 35a.

[0077] Other configurations in Embodiment 5 are the same as those in Embodiment 1.

[0078] This configuration also provides the same effects as in Embodiment 1. Furthermore, since each of the pair of gripping arms 35 is provided with a contact surface 35a, there is no need to be concerned with the installation accuracy of the fastener plate 60, and the positional relationship between the rail position adjustment device 30 and the rail member 24 can be easily adjusted to the appropriate position.

[0079] Embodiment 6. Next, Figure 13 is a perspective view showing the rail position adjustment device 30 according to Embodiment 6. The rail moving device 32 of Embodiment 6 is configured to grip the rail bracket 25 with a pair of gripping arms 35.

[0080] Other configurations in Embodiment 6 are the same as those in Embodiment 1.

[0081] This configuration also provides the same effects as in Embodiment 1. Furthermore, since the rail bracket 25 is gripped by a pair of gripping arms 35, the overall height dimension of the rail position adjustment device 30 can be reduced compared to the case where the rail member 24 is gripped while avoiding the rail bracket 25. This makes it possible to reduce the weight of the rail position adjustment device 30.

[0082] In addition, the rail moving device 32 in embodiments 2 to 5 may be configured to grip the rail bracket 25 with a pair of gripping arms 35.

[0083] Embodiment 7. Next, Figure 14 is a perspective view showing the rail position adjustment device 30 according to Embodiment 7. The base 31 of Embodiment 7 has an extension plate 49 in addition to a pair of leg members 33 and a support plate 34. The planar shape of the extension plate 49 is U-shaped.

[0084] The extension plate 49 is attached to the fastener plate 60 by a pair of gripping devices 61. The extension plate 49 also surrounds the rail member 24 between itself and the fastener plate 60.

[0085] The rail moving device 32 is supported on the extension plate 49 via a pair of leg members 33 and a support plate 34 in front of the rail member 24. That is, the rail moving device 32 is supported on the base 31 in front of the rail member 24.

[0086] As a result, the rail moving device 32 grips the rail member 24 from the front side of the rail member 24, rather than from the fastener plate 60 side, using a pair of gripping arms 35.

[0087] Other configurations in Embodiment 7 are the same as those in Embodiment 1.

[0088] This configuration also provides the same effects as in Embodiment 1. Furthermore, since the position of the rail body 26 can be adjusted from the front of the rail member 24, the efficiency of the position adjustment work can be improved.

[0089] In Embodiment 7, a portion of the load acting on the extension plate 49 may be supplementarily supported by a work platform or gondola (not shown) positioned in front of the rail member 24.

[0090] Furthermore, in embodiments 2 to 6, similar to embodiment 7, the rail moving device 32 may be supported on the base 31 in front of the rail member 24.

[0091] Embodiment 8. Next, Figure 15 is a perspective view showing the rail position adjustment device 30 according to Embodiment 8. In Embodiment 8, the rail position adjustment device 30 is attached to the lower side of the fastener plate 60.

[0092] Other configurations in Embodiment 8 are the same as those in any of Embodiments 1 to 6.

[0093] Thus, the rail position adjustment device 30 may be attached to the underside of the fastener plate 60. In this case, the overall height dimension of the rail position adjustment device 30 can be reduced compared to the case where the rail member 24 is gripped while avoiding the rail bracket 25. This makes it possible to reduce the weight of the rail position adjustment device 30.

[0094] Embodiment 9. Next, Figure 16 is a perspective view showing the rail position adjustment device 30 according to Embodiment 9. In Embodiment 9, the rail moving device 32 is provided in front of the rail member 24, on the underside of the extension plate 49 via a pair of leg members 33 and a support plate 34.

[0095] Other configurations in Embodiment 9 are the same as those in Embodiment 7.

[0096] Thus, the rail moving device 32 may be positioned below the extension plate 49. Compared to the case where the rail member 24 is gripped while avoiding the rail bracket 25, the overall height dimension of the rail position adjustment device 30 can be reduced. This makes it possible to reduce the weight of the rail position adjustment device 30.

[0097] Embodiment 10. Next, Figure 17 is a perspective view showing the rail position adjustment device 30 according to Embodiment 10. The base 31 of Embodiment 10 has an XY stage 50 in addition to a pair of leg members 33 and a support plate 34.

[0098] The XY stage 50 is interposed between a pair of leg members 33 and a support plate 34. The XY stage 50 can move the support plate 34 relative to the pair of leg members 33 in two orthogonal directions in the horizontal plane, either manually or by the driving force of an actuator. That is, with the base 31 attached to the fastener plate 60, the XY stage 50 can move the rail moving device 32 in two orthogonal directions in the horizontal plane.

[0099] Other configurations in Embodiment 10 are the same as those in Embodiment 1.

[0100] This configuration also provides the same effects as in Embodiment 1. Furthermore, since the XY stage 50 is provided on the base 31, the horizontal position of the rail moving device 32 can be adjusted even after the base 31 has been attached to the fastener plate 60.

[0101] In addition, an XY stage 50 may be provided on the base 31 of embodiments 2 to 9.

[0102] Furthermore, in embodiments 1 to 10, the method of attaching the base 31 to the fastener plate 60 is not limited to an attachment method using a gripping device 61 or a fastener 62, but may also be an attachment method using, for example, a permanent magnet or an electromagnet.

[0103] Furthermore, in embodiments 1 to 10, the drive source in the arm drive mechanism 36 is not limited to a motor, but may also be a hydraulic cylinder, a pneumatic cylinder, a linear actuator, or the like.

[0104] Furthermore, the overall elevator layout is not limited to the layout shown in Figure 1. For example, the roping system could be a 2:1 roping system.

[0105] Furthermore, the elevator may be a machine-room-less elevator, a double-deck elevator, or a single-shaft multi-car elevator. In a single-shaft multi-car elevator, the upper car and the lower car, located directly below the upper car, each move independently up and down a common hoistway.

[0106] Although preferred embodiments have been described in detail above, the invention is not limited to the embodiments described above, and various modifications and substitutions can be made to the embodiments described above without departing from the scope of the claims.
