  However, when the hoisting machine is supported by, for example, anti-vibration rubber, the positional relationship between the hoisting machine and the deflecting wheel changes due to the vibration of the hoisting machine. Lateral vibration occurs on the main rope. In this case, when the rope brake device disclosed in Patent Documents 1 and 2 is applied to an elevator device, the main rope contacts the friction material every time the main rope vibrates, and the friction material wears. Will be shorter.

  Further, even in the elevator apparatus disclosed in Patent Document 3, since only one of the main ropes has a roller for adjusting the arrangement of the main ropes, it is not possible to prevent the main rope from vibrating laterally to the side where the rollers are not arranged. . For this reason, the friction material of the rope brake device is worn by contact with the main rope, and the life of the friction material is shortened.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to obtain an elevator apparatus capable of extending the life of a rope brake device.

  An elevator apparatus according to the present invention includes a car that can be raised and lowered in a hoistway, a main rope that suspends a car, and a drive sheave around which the main rope is wound, supported by a vibration isolator, and driven by rotation of the drive sheave. And a rope brake device that is disposed away from the drive sheave and applies a braking force to the main rope, and the rope brake device includes a rope brake device main body including a grip portion that can hold the main rope; And a main rope guide portion disposed in a position closer to the drive sheave than the grip portion, and the main rope guide portion includes a pair of rollers that sandwich the main rope.

  In the elevator apparatus according to the present invention, the main rope guide portion is disposed at a position closer to the drive sheave than the grip portion, and the main rope guide portion has a pair of rollers that sandwich the main rope. Even when the supported hoisting machine vibrates, lateral vibration of the main rope transmitted from the drive sheave can be suppressed by the main rope guide part, and lateral vibration of the main rope at the position of the gripping part is more reliably ensured. Can be suppressed. Thereby, it is possible to prevent the main rope from coming into contact with the grip portion due to the lateral vibration of the main rope, and unnecessary wear of the grip portion can be avoided. Therefore, the life of the rope brake device can be extended.

Embodiment 1 FIG.
1 is a block diagram showing an elevator apparatus according to Embodiment 1 of the present invention. FIG. 2 is a block diagram showing the upper part of the elevator apparatus of FIG. In the figure, a machine room 2 is provided in the upper part of the hoistway 1. On a beam that partitions the hoistway 1 and the machine room 2, a vibration isolator 3 having a plurality of vibration isolating rubbers is installed. In the machine room 2, a hoisting machine (driving device) 4 supported by a vibration isolator 3 is arranged.

  The hoisting machine 4 includes a hoisting machine main body 5 including a motor 5 a and a driving sheave 6 provided in the hoisting machine main body 5 and rotated by the driving force of the hoisting machine main body 5. The hoisting machine body 5 is provided with a hoisting machine brake that applies a braking force to the drive sheave 6. The impact generated by the rotation of the drive sheave 6 is absorbed by the vibration isolator 3 while the hoisting machine 4 vibrates.

  A deflecting wheel 7 disposed away from the drive sheave 6 is attached to a beam that partitions the hoistway 1 and the machine room 2. The baffle wheel 7 is arranged at a position lower than the drive sheave 6 and is shifted in the horizontal direction with respect to the drive sheave 6. In this example, the deflector wheel 7 is attached to the beam in a state of being located below the upper surface of the beam.

  In the hoistway 1, as shown in FIG. 1, a car 8 and a counterweight 9 are provided so as to be able to move up and down. A plurality of main ropes 10 for suspending a car 8 and a counterweight 9 are wound around the drive sheave 6 and the deflecting wheel 7. As a result, each main rope 10 is inclined with respect to the horizontal plane in the section between the drive sheave 6 and the deflector wheel 7. For example, a rope or a belt is used as the main rope 10. In this example, one end of each main rope 10 is connected to the car 8 and the other end of each main rope 10 is connected to the counterweight 9. Further, the main ropes 10 are arranged at intervals in the axial direction of the drive sheave 6. The car 8 and the counterweight 9 are raised and lowered in the hoistway 1 by the rotation of the drive sheave 6. When the hoisting machine 4 vibrates, the drive sheave 6 vibrates with respect to the deflector wheel 7, and thus lateral vibration occurs in a portion of each main rope 10 between the drive sheave 6 and the deflector wheel 7.

  In the machine room 2, a rope brake device 12 that applies a braking force to each main rope 10 is provided. The rope brake device 12 is disposed between the drive sheave 6 and the deflector wheel 7 in the longitudinal direction of the main rope 10. The rope brake device 12 is disposed away from each of the drive sheave 6 and the deflector wheel 7. The rope brake device 12 is attached via a support shaft 14 to a base 13 fixed to a beam that partitions the hoistway 1 and the machine room 2. The support shaft 14 is disposed parallel to the axis of the drive sheave 6.

  The base 13 is provided with a fixing bolt (not shown) for fixing the rope brake device 12 to the base 13 and the support shaft 14. The rope brake device 12 can be rotated around the support shaft 14 by loosening the fixing bolt, and is fixed to the base 13 and the support shaft 14 by tightening the fixing bolt. The rope brake device 12 is disposed along the length direction of the main rope 10 in a state where the rope brake device 12 is inclined with respect to a horizontal plane by tightening a fixing bolt.

  The hoisting machine 4 and the rope brake device 12 are operated by the control of the control device 11 that controls the operation of the elevator. Examples of the case where the rope brake device 12 is operated include, for example, when a power failure occurs or when the hoisting machine brake is abnormal. The control device 11 is disposed in the machine room 2.

  FIG. 3 is a partially broken configuration diagram showing a state in which the braking force applied to the main rope 10 by the rope brake device 12 of FIG. 2 is released. 4 is a cross-sectional view taken along line IV-IV in FIG. Further, FIG. 5 is a partially broken configuration diagram showing a state where the rope brake device 12 of FIG. 3 gives a braking force to the main rope 10. In the figure, a rope brake device 12 is provided on a rope brake device body 15, a rope brake device body 15, a main rope guide portion 16 that suppresses lateral vibration of the main rope 10, and a support shaft 14. It has a common housing 19 to which the apparatus main body 15 and the main rope guide portion 16 are attached.

  The casing 19 can be rotated around the support shaft 14 by loosening the fixing bolt, and is fixed to the base 13 and the support shaft 14 by tightening the fixing bolt. The rope brake device main body 15 and the main rope guide portion 16 can be rotated around the support shaft 14 together with the housing 19 by loosening the fixing bolts.

  The rope brake device main body 15 applies a braking force to the main rope 10 by gripping a portion of each main rope 10 between the drive sheave 6 and the deflector wheel 7. The rope brake device main body 15 includes a gripping portion 17 that can grip each main rope 10 and an electromagnetic actuator 18 that drives the gripping portion 17 under the control of the control device 11.

  The gripping portion 17 has a pair of braking members 20 and 21 each including a friction material (lining), and a link 22 that is rotatably connected between the braking members 20 and 21.

  The link 22 is rotatable about a link shaft 23 provided in the housing 19. The link shaft 23 is disposed in parallel with the support shaft 14. An intermediate portion of the link 22 is attached to the link shaft 23. One brake member 20 is rotatably attached to one end of the link 22, and the other brake member 21 is rotatably attached to the other end of the link 22.

  Each braking member 20, 21 is arranged with the friction material facing each other via each main rope 10. Further, each braking member 20, 21 is arranged along the length direction of each main rope 10. Further, each braking member 20, 21 is in contact with the main rope 10 by the rotation of the link 22 around the link shaft 23 (FIG. 5), and each main rope 10. It is possible to move away from the release position (FIG. 3) where the main rope 10 is released from the release position. When each brake member 20, 21 is in the release position, a predetermined distance is maintained between each brake member 20, 21. The gripping portion 17 applies a braking force to each main rope 10 by displacing each brake member 20, 21 to the grip position, and controls each main rope 10 by displacing each brake member 20, 21 to the release position. Release power.

  The electromagnetic actuator 18 is disposed outside the one braking member 21. Further, the electromagnetic actuator 18 is against an urging force of the elastic spring 25 and an elastic spring (biasing body) 25 that urges one of the braking members 21 in a direction in which each of the braking members 20 and 21 is displaced to the gripping position. Each of the braking members 20 and 21 has an electromagnetic magnet 24 that displaces one of the braking members 21 in the direction in which the braking member 20 or 21 is displaced to the release position.

  The electromagnetic magnet 24 has an electromagnetic coil 24a. The electromagnetic magnet 24 generates an electromagnetic attractive force that attracts the braking member 21 when energized to the electromagnetic coil 24a, and stops generating the electromagnetic attractive force when the energization to the electromagnetic coil 24a is stopped. Control of energization to the electromagnetic coil 24 a is performed by the control device 11.

  Each braking member 20, 21 is displaced to the release position against the urging force of the elastic spring 25 when the electromagnetic magnet 24 generates an electromagnetic attractive force. In addition, each of the braking members 20 and 21 is displaced to the gripping position by the biasing force of the elastic spring 25 when the electromagnetic magnet 24 stops generating the electromagnetic attractive force.

  The main rope guide portion 16 is disposed at a position closer to the drive sheave 6 than the grip portion 17 in the length direction of each main rope 10. The main rope guide portion 16 includes a pair of rollers (rotating bodies) 26 that sandwich the main ropes 10 together. As shown in FIGS. 3 and 5, each roller 26 is disposed at the same position in the length direction of the main rope 10.

  The axis of each roller 26 is arranged in parallel with the support shaft 14 along the arrangement direction of the main ropes 10. As shown in FIG. 4, roller mounting blocks 28 fixed to the housing 19 are rotatably attached to both ends of the shafts of the rollers 26 via bearings 27.

  One roller mounting block 28 and the other roller mounting block 28 attached to the shaft of each roller 26 are provided between a bolt 29 screwed into the housing 19 and a protrusion (receiving portion) 30 fixed to the housing 19. Has been placed. Each roller mounting block 28 is clamped together between the bolt 29 and the protrusion 30 and fixed to the housing 19 by tightening the bolt 29 in a direction approaching the protrusion 30. Thereby, each roller 26 is attached to the housing 19 while being pressed against the main rope 10.

  As shown in FIG. 4, a plurality of grooves 31 extending in the circumferential direction of the roller 26 are provided on the outer peripheral portion of each roller 26. Each main rope 10 is sandwiched between the rollers 26 in a state of being fitted in the grooves 31 of the pair of rollers 26. Each roller 26 rotates with the movement of each main rope 10. As a material constituting each roller 26, for example, resin or metal is used. Lateral vibration of each main rope 10 caused by vibration of the hoisting machine 4 is suppressed in a section farther from the drive sheave 6 than the main rope guide portion 16 when each main rope 10 is sandwiched between the rollers 26.

  Next, the operation will be described. During normal operation of the elevator, the electromagnetic coil 24a is energized under the control of the control device 11, and the braking members 20 and 21 are arranged at the release position (FIG. 3). Thereby, the provision of the braking force to each main rope 10 by the rope brake device 12 is released.

  When the drive sheave 6 is rotated by the control of the control device 11 with respect to the hoisting machine 4, vibration is generated in the hoisting machine 4 supported by the vibration isolator 3. Thereby, a lateral vibration corresponding to the vibration of the drive sheave 6 is generated in each main rope 10. At this time, since each main rope 10 is sandwiched between the rollers 26 of the main rope guide portion 16, each main rope 10 is in a section farther from the drive sheave 6 than the main rope guide portion 16 in each main rope 10. Is suppressed. Thereby, it is avoided that each main rope 10 contacts each brake member 20,21.

  For example, when a power outage or hoisting machine brake abnormality occurs, the energization of the electromagnetic coil 24a is stopped. As a result, the generation of the electromagnetic attractive force of the electromagnetic magnet 24 is stopped, and the braking members 20 and 21 are displaced to the gripping position (FIG. 5) by the urging force of the elastic spring 25. Thereby, a braking force is applied to each main rope 10.

  In such an elevator device, the main rope guide portion 16 is disposed at a position closer to the drive sheave 6 than the grip portion 17 of the rope brake device main body 15, and the main rope guide portion 16 is a pair of rollers that sandwich each main rope 10. 26, the main rope guide guides the lateral vibration of the main rope 10 transmitted from the drive sheave 6 even when the hoisting machine 4 supported by the vibration isolator 3 vibrates with respect to the deflector wheel 7. It can suppress by the part 16, and can suppress more reliably the lateral vibration of the main rope 10 in the position of the holding part 17. FIG. Thereby, it is possible to prevent the main rope 10 from coming into contact with the gripping portion 17 due to the lateral vibration of the main rope 10, and unnecessary wear of the gripping portion 17 can be avoided. Therefore, the life of the rope brake device 12 can be extended.

  Further, since the rope brake device 12 is disposed between the drive sheave 6 and the deflector wheel 7 in the longitudinal direction of the main rope 10, the inclination of the main rope 10 changes due to the raising and lowering of the car 8 and the counterweight 9. Therefore, the operation of the rope brake device 12 can be performed more stably, and the main rope 10 can be more reliably prevented from coming into contact with the grip portion 17 due to the lateral vibration of the main rope 10. In addition, operations such as installation and maintenance of the rope brake device 12 can be facilitated.

Embodiment 2. FIG.
6 is a partially broken configuration diagram showing a rope brake device 12 of an elevator apparatus according to Embodiment 2 of the present invention. In the figure, a mounting member 41 formed in a crank shape is fixed to the casing 19 with fixing bolts 29. Of the pair of rollers 26 of the main rope guide portion 16, one roller 26 is attached to the attachment member 41, and the other roller 26 is attached to the housing 19. Accordingly, the rollers 26 are arranged so as to be shifted from each other in the length direction of the main ropes 10 so that the main ropes 10 are bent by pressing the rollers 26 against the main ropes 10.

  One roller 26 is attached to the attachment member 41 via a roller position adjustment unit 42. The roller position adjustment unit 42 can adjust the position of one roller 26 with respect to the other roller 26 in a direction in which the bending amount of the main rope 10 changes. In this example, the roller position adjusting unit 42 displaces one roller 26 in a direction perpendicular to both the length direction of the main rope 10 and the arrangement direction of the main ropes 10, thereby causing the other roller 26 to move. The position of one roller 26 with respect to is adjusted.

  The mounting member 41 is disposed between a pair of restricting plates (restricting portions) 41a and 41b that face each other in the direction in which one roller 26 is displaced, and the restricting plates 41a and 41b, and displaces one roller 26. A rail 41c arranged along the direction is fixed.

  The roller position adjusting unit 42 is contracted between the roller mounting block 43 guided by the rail 41c between the regulation plates 41a and 41b, and between the roller mounting block 43 and one regulation plate 41a, and the other regulation plate. An elastic spring 44 that urges the roller mounting block 43 in a direction approaching 41b, and an adjustment bolt 45 that is screwed into the other regulating plate 41b and receives the roller mounting block 43 that is urged by the elastic spring 44. doing.

  One roller 26 is rotatably attached to a roller attachment block 43. One roller 26 is displaced along the rail 41c with respect to the mounting member 41 by adjusting the screwing amount of the adjusting bolt 45 to the other regulating plate 41b while turning the adjusting bolt 45. The position of one roller 26 with respect to the other roller 26 is adjusted in a direction in which the amount of bending of the main rope 10 changes by adjusting the screwing amount of the adjusting bolt 45 with respect to the other restricting plate 41b. The main rope guide portion 16 has a pair of rollers 26 and a roller position adjustment portion 42. Other configurations are the same as those in the first embodiment.

  In such an elevator apparatus, the rollers 26 of the main rope guide portion 16 are arranged so as to be shifted from each other in the length direction of the main rope 10 so that the main rope 10 is bent by pressing the rollers 26 against the main rope 10. The contact area of the main rope 10 with respect to each roller 26 can be increased, the lateral vibration of the main rope 10 can be further reliably suppressed, and the main rope 10 can be made difficult to come off from between the rollers 26. .

  Further, the position of one roller 26 with respect to the other roller 26 can be adjusted by the roller position adjusting unit 42 in a direction in which the bending amount of the main rope 10 changes, so that each roller 26 is pressed against the main rope 10. The amount can be easily adjusted.

  In the above example, the position of one roller 26 with respect to the other roller 26 can be adjusted by the roller position adjusting unit 42, but the positional relationship of each roller 26 is fixed without using the roller position adjusting unit 42. You may do it. In this case, one roller 26 is directly attached to the attachment member 41.

Embodiment 3 FIG.
In the second embodiment, the main rope guide portion 16 is disposed only at a position closer to the drive sheave 6 than the grip portion 17, but not only from the position closer to the drive sheave 6 than the grip portion 17, but also from the grip portion 17. Alternatively, the main rope guide portion may be arranged at a position away from the drive sheave 6.

In the drawing, the rope brake device 12 includes a rope brake device main body 15 and a position closer to the drive sheave 6 than the gripping portion 17 of the rope brake device main body 15 and a drive sheave than the gripping portion 17 in the longitudinal direction of the main rope 10. 6 and a pair of main rope guide portions 16 and 51 arranged at respective positions away from 6. The configuration of each main rope guide portion 16, 51 is the same as that of the main rope guide portion 16 of the second embodiment. Accordingly, the gripping portion 17 can grip a portion of the main rope 10 positioned between the pair of main rope guide portions 16 and 51 that are arranged apart from each other in the length direction of the main rope 10.

  In this example, since the other main rope guide portion 51 is disposed between the gripping portion 17 and the counterweight 9, a change in the inclination of the main rope 10 as the counterweight 9 moves up and down, Even if lateral vibration occurs, lateral vibration of the main rope 10 is suppressed by the other main rope guide portion 51, and the main rope 10 is prevented from contacting the grip portion 17. Other configurations are the same as those of the second embodiment.

  In such an elevator apparatus, in the longitudinal direction of the main rope 10, the main rope guide portion 16 is located at a position closer to the drive sheave 6 than the grip portion 17 and a position farther from the drive sheave 6 than the grip portion 17. , 51 are arranged, not only the lateral vibration of the main rope 10 transmitted from the side closer to the drive sheave 6 than the gripping portion 17 but also the lateral vibration transmitted from the side farther from the drive sheave 6 than the gripping portion 17 is. Thus, the vibration of the main rope 10 located between the main rope guide portions 16 and 51 can be further reliably suppressed. Thereby, it can prevent more reliably that each main rope 10 contacts the holding | grip part 17 by the horizontal vibration of a main rope 10, a side shake, etc., and can further aim at the lifetime improvement of the rope brake apparatus 12.
