Description

  The present invention relates to an elevator that lifts and lowers a hoistway provided in a building structure to carry people and luggage, and in particular, shakes of a long body such as a main rope and a balancing rope that connect a carriage and a balancing weight. The present invention relates to an elevator provided with a suppression device for suppressing vibration.

  Generally, a rope type elevator is a main rope that connects a car and a counterweight in a hoistway, and a governor rope that is used to detect the speed of the counter rope, the car or the counterweight. Etc. are arranged. This elongate body is not fixed or supported between the hoisting machine, the speed governor, and the pulley. For this reason, the long body sometimes sways due to the influence of the shaking of the building due to an earthquake or a strong wind.

  In recent years, building structures have been increasing in height. And the length of a long body becomes long, so that the height of a building structure becomes high (long). Furthermore, the natural period in the long body becomes longer as the length of the long body becomes longer. In addition, when a so-called resonance occurs in which the period of shaking of the building structure coincides with the period of shaking of the long body, the longer the natural period of the long body, the greater the tendency of shaking. And when a long body shakes greatly in a hoistway, there existed a possibility that the shaken long body might contact with the apparatus installed in the hoistway, or a long body might be caught by an apparatus.

  Therefore, in the technique described in Patent Document 1, when the displacement and acceleration of the building structure are measured to calculate the magnitude of shaking of the long body, and when the long body is greatly shaken, Has been proposed to control the car to the nearest floor. However, although the technique described in Patent Document 1 can detect the magnitude of the shaking of the long body, the long body has not been suppressed, so the long body is installed in the hoistway. It was not possible to prevent contact with the equipment that was used.

  As a conventional technique for suppressing shaking of a long body, for example, there is a technique described in Patent Document 2. In the technique described in Patent Document 2, a rope steadying member through which a main rope is inserted is provided in a hoistway. And if a car moves upwards, a rope steadying body will be mounted in the upper part of a car.

  Further, when the long body shakes, the car and the counterweight connected to the long body move in the vertical direction. Therefore, in the technique described in Patent Document 3, a car restraining device that restrains vertical displacement of the car and a counterweight that restrains vertical displacement of the counterweight while the car is stopped. A restraining device. And the swing of the main rope is suppressed by restraining the vertical displacement of the ride car and the counterweight.

  Furthermore, in the technique described in Patent Document 4, a tilting arm that is supported so as to be able to rotate to suppress the swinging of the rope is provided. Then, depending on the position of the car, the tilting arm is rotated from a state substantially parallel to the track on which the car travels to a state substantially perpendicular to the track on which the car travels.

  However, in the technique described in Patent Document 2, when the building structure becomes taller and the distance traveled by the car becomes longer, the number of rope steady rests placed on the car increases. As a result, there has been a problem that the weight of the car increases due to the plurality of rope steady rests placed on the upper part of the car. Furthermore, since the rope steadying body is disposed on the track on which the car travels, there is a possibility that a large impact may occur when the rope steadying body is placed on the top of the car. For this reason, the technique described in Patent Document 2 has a problem that the moving speed of the car cannot be increased.

  Further, in the technique described in Patent Document 3, by restraining the vertical displacement of the car and the counterweight, when the main body is greatly shaken, the car and the counterweight and the elongate body A heavy load is applied to the connection point. Therefore, in the technique described in Patent Document 3, it is necessary to increase the number of main ropes or to increase the connection strength of the connection points between the main ropes and the car.

  In the technique described in Patent Document 4, the tilt arm is rotated by a motor that operates using electricity as a driving force. Furthermore, in order to drive the motor according to the position of the car, it is necessary to provide a control unit for controlling the motor. As a result, in the technique described in Patent Document 4, it is necessary to install electric wiring for connecting electronic components such as a motor and a control unit in the hoistway, which is very troublesome.

  The object of the present invention is to take the above-mentioned problems into consideration, without obstructing the traveling of the car, without increasing the strength of the connection point between the rope and the car, or without installing the electric wiring in the hoistway. It is in providing the elevator which can suppress the swing of a rope.

  In order to solve the above-mentioned problems and achieve the object of the present invention, the elevator of the present invention is connected to a car that moves up and down in the hoistway and the car via a main rope, and moves up and down in the hoistway. A counterweight and a long body disposed in the hoistway are provided. And the elevator is provided with the shaking suppression apparatus and the follow-up rope. The shaking suppression device suppresses shaking of the long body. The follow-up rope moves following the raising / lowering operation of the car or the counterweight. Furthermore, the shaking suppression device includes a suppression member, a support mechanism, a retracting mechanism, and a transmission mechanism. The suppressing member approaches or contacts the long body and suppresses the shaking of the long body. The support mechanism supports the restraining member in a state in which the restraining member protrudes by an elastic force into the track on which the car or the counterweight travels. The retracting mechanism retracts the restraining member against the elastic force of the support mechanism from the track on which the car and the counterweight travel. And a transmission mechanism transmits the force which a follower rope moves to a retracting mechanism as a driving force of a retracting mechanism.

  As a driving force for driving the retreat mechanism, a force generated when the follower rope moves following the raising / lowering operation of the car or the counterweight is used. Further, when the car or the counterweight stops, the movement of the follow-up rope also stops, so that the force for driving the retracting mechanism is lost. Therefore, when the car or the counterweight stops, the restraining member protrudes into the track on which the car or the counterweight travels due to the elastic force of the support mechanism. Thus, the retracting mechanism operates in accordance with the raising / lowering operation of the car or the counterweight.

  According to the elevator of the present invention, the retraction mechanism is driven without using electronic components such as a motor and a control unit that operate using electricity as a driving force, and the restraining member is moved outward from the track on which the car and the counterweight travel. Can be evacuated. In addition, since the retracting mechanism operates in accordance with the movement of the car and the counterweight, it is possible to prevent the restraining member that suppresses the shaking of the long body from obstructing the traveling of the car or the counterweight. Furthermore, when the car or the counterweight stops, the restraining member can restrain the long body from shaking.

Hereinafter, embodiments of an elevator according to the present invention will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected to the common member in each figure. Moreover, although description is given in the following order, this invention is not necessarily limited to the following forms.
1. 1. First embodiment 1-1. Configuration of elevator 1-2. 1. Operation of the vibration suppression device Second embodiment example 3. FIG. 3. Third embodiment example Fourth embodiment

1. First embodiment example 1-1. First, a first embodiment of an elevator according to the present invention (hereinafter referred to as “this example”) will be described with reference to FIGS.
FIG. 1 is an explanatory view schematically showing the elevator of this example, and FIG. 2 is an explanatory view schematically showing a state in which each rope is wound. FIG. 3 is a plan view showing the inside of the hoistway as viewed from above.

  As shown in FIG. 1, the elevator 1 includes a car 3 that moves up and down in a hoistway 2 formed in a building structure, a counterweight 6, a hoisting machine 8, and a curling wheel 9 (see FIG. 2). ), A speed governor 10, and a shake suppression device 20. The hoisting machine 8 and the warping wheel 9 and the speed governor 10 are arranged in a machine room 2 a provided in the upper part of the hoistway 2.

  The car 3 is formed in a hollow, substantially rectangular parallelepiped shape, and carries a person or luggage. The car 3 has a slider 3a. The slider 3 a is fixed to the outside of the car 3. The slider 3a is slidably supported on a guide rail 11 provided in the hoistway 2. Therefore, the car 3 moves up and down in the hoistway 2 along the guide rail 11. As shown in FIG. 2, the elevator 1 has a main rope 4 that connects the upper portion of the car 3 and the upper portion of the counterweight 6.

  The main rope 4 is wound around a hoisting machine 8 installed in the machine room 2a. The hoisting machine 8 raises and lowers the car 3 and the counterweight 6 via the main rope 4. A curling wheel 9 is disposed in the vicinity of the hoisting machine 8. The main rope 4 is mounted on the curving wheel 9.

  The counterweight 6 is set to have substantially the same mass as the weight of the car 3 when not loaded, plus half the weight of the car 3 that can be loaded. Therefore, when a weight of half of the maximum load weight is loaded in the car 3, the tension ratio of the main rope 4 on the car 3 side and the counterweight 6 side is 1. As a result, the output torque of the hoisting machine 8 is maximized both when the vehicle 3 is not loaded with objects and people and when the vehicle 3 is fully loaded with objects and people fully loaded. However, the necessary output of the hoisting machine 8 can be minimized.

  Further, in the elevator 1, when the elevator car 3 and the counterweight 6 are moved up and down, the length of the main rope 4 changes depending on the position of the car 3, so that the tension on the car 3 side on the hoisting machine 8. And the difference in tension on the counterweight 6 side increases. Therefore, in this example, a balancing rope 14 is provided at the lower part of the car 3 and the lower part of the counterweight 6. The weight of the balancing rope 14 is set to be equal to or substantially equal to the weight of the main rope 4. This reduces the difference between the tension on the car 3 side and the tension on the counterweight 6 side of the main rope 4 on the hoisting machine 8.

  A balancing pulley 12 is disposed at the lowermost part of the hoistway 2. A balancing rope 14 is wound around the balancing pulley 12.

  As shown in FIGS. 1 and 3, the main rope 4 and the balancing rope 14 are composed of a plurality of ropes (in this example, five). As shown in FIG. 3, the main rope 4 is fixed to the approximate center of the upper part of the car 3, and the balancing rope 14 is fixed to the approximate center of the lower part of the car 3. A plurality of ropes constituting the main rope 4 and the balancing rope 14 are arranged along the short direction of the car 3.

  A speed governor 10 is installed in the machine room 2 a of the hoistway 2. A governor rope 15 is wound around the governor 10. The governor rope 15 is formed in a so-called endless shape in which both ends in the axial direction are connected to each other. A part of the governor rope 15 is connected to the car 3 via a connecting member 16. A tension wheel 13 around which a governor rope 15 is wound is disposed in the lower part of the hoistway 2.

  The governor rope 15 circulates in accordance with the raising / lowering operation of the car 3. The governor rope 15 is wound around the governor 10 and the tension wheel 13 while drawing a ring, and a part thereof is connected to the car 3 via the connecting member 16. Therefore, a rope (hereinafter referred to as “connection side rope”) 15a on the side of the connecting member 16 across the speed governor 10 and the tension wheel 13 in the speed governor rope 15 moves in the same direction as the car 3 (FIG. 12A). reference). Then, a rope (hereinafter referred to as “return rope”) 15b opposite to the connection side rope 15a across the speed governor 10 and the tensioning wheel 13 in the speed governor rope 15 moves in a direction opposite to the car 3. (See FIG. 12A). The governor 10 detects the speed of the car from the circulation speed of the governor rope 15.

  Further, as shown in FIG. 2, in this example, the counterweight 6 is also provided with a counterweight 10 </ b> A for the counterweight. Similar to the speed governor 10, a speed governor rope 15 </ b> A for a counterweight is wound around the speed governor 10 </ b> A for the counterweight. The counterweight governor rope 15A for the counterweight is formed in an endless shape, and a part thereof is connected to the counterweight 6 via the connecting member 16A. A tension wheel 13A around which a balancing weight governor rope 15A is wound is disposed in the lower part of the hoistway 2. Similar to the governor rope 15, the balance weight governor rope 15 </ b> A circulates and moves in accordance with the lifting / lowering operation of the counterweight 6.

  As shown in FIG. 1 and FIG. 2, a shake suppression device 20 is installed at a position where the main rope 4 and the balancing rope 14 in the elevator 1 become maximum when they resonate.

[Configuration of vibration suppression device]
Next, the configuration of the vibration suppressing device 20 will be described with reference to FIGS.
FIG. 4 is a side view showing the vibration suppressing device 20.

  As shown in FIG. 3, the vibration suppression device 20 includes two suppression members 21 and 22, a retracting mechanism 23, a transmission mechanism 24, two interlocking mechanisms 30 and 30, and two support springs 25 a indicating a support mechanism. 25b (see FIG. 4). The first suppressing member 21 is disposed on one side of the elevator car 3 in the longitudinal direction of the hoistway 2. The second restraining member 22 is disposed on the other side in the longitudinal direction of the car 3 in the hoistway 2 and between the car 3 and the counterweight 6.

  The first restraining member 21 and the second restraining member 22 have a restraining portion 26 that contacts or approaches the main rope 4 or the balancing rope 14 and a pair of rotating arms 27 that support the restraining portion 26. Yes. The main rope 4 or the balancing rope 14 is sandwiched between the suppression portion 26 of the first suppression member 21 and the suppression portion 26 of the second suppression member 22.

  The suppression part 26 is formed from the cylindrical rod-shaped member. In addition, the shape of the suppression part 26 is not limited to a cylinder, For example, you may form in a prismatic shape. When the suppressing part 26 is formed in a prismatic shape, it is preferable that the area in contact with the main rope 4 or the balancing rope 14 is smoothly chamfered. Thereby, when the suppressing part 26 contacts the main rope 4 or the balancing rope 14, the main rope 4 or the balancing rope 14 can be prevented from being damaged by the suppressing part 26.

  Furthermore, a rotatable roller may be provided in the suppressing unit 26. Thereby, the friction coefficient between the suppressing portion 26 and the main rope 4 or the balancing rope 14 can be reduced, and the suppressing portion 26 can be more effectively prevented from damaging the main rope 4 or the balancing rope 14. it can.

  Rotating arms 27 are provided at both axial ends of the suppression unit 26. The rotating arm 27 is formed from a rod-shaped member. A restraining portion 26 is fixed to one end of the pivot arm 27 in the axial direction, and a first restraining mechanism 23 to be described later is disposed at the other end of the first restraining member 21 in the axial direction of the pivot arm 27. A rotating shaft 31 is provided. In addition, a second rotation shaft 36 to be described later is provided at the other axial end of the rotation arm 27 in the second suppressing member 22.

  Further, as shown in FIG. 4, one end portions of the first support spring 25 a and the second support spring 25 b are fixed to a midway portion in the axial direction of the rotation arm 27 in the first suppressing member 21. . The first support spring 25 a is arranged at the upper part in the vertical direction of the rotation arm 27, and the second support spring 25 b is arranged at the lower part in the vertical direction of the rotation arm 27. As described above, one end portions of the first support spring 25a and the second support spring 25b are fixed to the rotating arm 27, and the other end portions of the first support spring 25a and the second support spring 25b are It is fixed to the wall surface of the hoistway 2.

  The spring constant of the first support spring 25a is set to be larger by the weight of the first restraining member 21 than the spring constant of the second support spring 25b. The rotating arm 27 is horizontally supported by the first support spring 25a and the second support spring 25b. Therefore, the rotating arm 27 is orthogonal to the wall surface of the hoistway 2.

  Further, a support spring (not shown) is also provided on the side of the rotation arm 27 of the second suppressing member 22. Since the second restraining member 22 moves in conjunction with the first restraining member 21 by an interlocking mechanism 30 described later, even if a support spring is provided only on the rotating arm 27 side of the first restraining member 21. Good. In this case, the spring constant of the first support spring 25a disposed on the upper portion of the rotation arm 27 is greater than the spring constant of the second support spring 25b. It is preferable to set a larger amount.

Next, the retracting mechanism 23 will be described.
The retraction mechanism 23 has a first rotation shaft 31, a second rotation shaft 36, and a driven member 33.

  The first rotation shaft 31 is disposed on one side of the elevator car 3 in the longitudinal direction of the hoistway 2. The first rotation shaft 31 is rotatably supported by bearing portions 32 and 32 provided in the hoistway 2. The second rotating shaft 36 is disposed on the other side in the longitudinal direction of the car 3 in the hoistway 2 and between the car 3 and the counterweight 6. The second rotation shaft 36 is movably supported by bearing portions 37 and 37 provided in the hoistway 2. The first rotation shaft 31 and the second rotation shaft 36 are arranged horizontally and parallel to each other.

  The first rotation shaft 31 and the second rotation shaft 36 are connected by a pair of interlocking mechanisms 30 and 30.

  The interlocking mechanism 30 includes an endless interlocking belt 38, a first interlocking pulley 39A, and a second interlocking pulley 39B. The first interlocking pulley 39A is fixed to the first rotating shaft 31, and the second interlocking pulley 39B is fixed to the second rotating shaft 36.

FIG. 5 is a side view showing the interlock mechanism 30.
As shown in FIG. 5, the interlocking belt 38 is stretched around the first interlocking pulley 39 </ b> A and the second interlocking pulley 39 </ b> B in an X shape, so-called a cross. When the first rotation shaft 31 is rotated by the interlocking mechanism 30, the second rotation shaft 36 is rotated in the opposite direction to the first rotation shaft 31 by the interlocking mechanism 30.

  As shown in FIG. 3, a driven member 33 is fixed to the first rotation shaft 31. The driven member 33 is formed in a semicircular shape as shown in FIG. The driven member 33 has a friction surface 33a, two concave portions 33b and 33b, and two rotary rollers 33c and 33c.

  The friction surface 33 a is an arc-shaped portion of the side surface of the driven member 33. A transmission mechanism 24 to be described later contacts the friction surface 33a. The two concave portions 33 b are formed at both ends in the circumferential direction of the friction surface 33 a of the driven member 33. The two recesses 33b are formed to be recessed in an arc from the side surface of the driven member 33. A rotating roller 33c is rotatably provided in each of the two recesses 33b (see FIG. 8).

Next, the transmission mechanism 24 will be described with reference to FIGS. 3 and 6 to 8.
FIG. 6 is a side view showing the transmission mechanism 24, and FIG. 7 is an explanatory view showing the transmission clutch 44 in the transmission mechanism 24. FIG. 8 is a perspective view showing a main part of the transmission mechanism 24.

  As shown in FIGS. 3 and 6, the transmission mechanism 24 includes a driving roller 41, a first transmission shaft 42, a first transmission pulley 43, a transmission clutch 44, a second transmission shaft 45, 2 transmission pulleys 46 and an endless transmission belt 47. The first transmission shaft 42 and the second transmission shaft 45 are supported by a support member 49 provided in the hoistway 2. The first transmission shaft 42 and the second transmission shaft 45 are disposed horizontally and parallel to each other. Further, the first transmission shaft 42 and the second transmission shaft 45 are arranged in parallel to the longitudinal direction of the car 3.

  The driving roller 41 is rotatably supported by the first transmission shaft 42. The driving roller 41 is pressed against the return side rope 15 b in the governor rope 15. Therefore, when the return side rope 15b moves, the driving roller 41 rotates. A first transmission pulley 43 is fixed to the driving roller 41. The first transmission pulley 43 is rotatably supported by the first transmission shaft 42.

  The transmission clutch 44 is rotatably supported by the second transmission shaft 45. A second transmission pulley 46 is fixed to the transmission clutch 44. The second transmission pulley 46 is rotatably supported by the second transmission shaft 45. A transmission belt 47 is stretched around the first transmission pulley 43 and the second transmission pulley 46 in an open belt shape, so-called parallel hooking. Therefore, when the driving roller 41 rotates, the transmission clutch 44 rotates in the same direction as the driving roller 41.

  As shown in FIG. 7A, the transmission clutch 44 includes a plurality of expansion members 44a, a weight portion 44b provided on the expansion member 44a, and a plurality of urging members 44c. The expansion member 44a is formed in a fan shape. The plurality of expansion members 44 a are arranged along the circumferential direction around the second transmission shaft 45. Thereby, the transmission clutch 44 is formed in a circular shape.

  Further, a weight portion 44b is provided on the outer side in the radial direction of the expansion member 44a. The weight portion 44b is provided with a biasing member 44c that biases the expansion member 44a and the weight portion 44b toward the second transmission shaft 45. Examples of the urging member 44c include a coil spring and a leaf spring. In this example, a coil spring is used as the biasing member 44c. As shown in FIG. 8, the plurality of expansion members 44a are housed between a pair of cover members 44d.

  As shown in FIGS. 3 and 6, when the transmission clutch 44 is not rotating, a gap is formed between the transmission clutch 44 and the driven member 33 of the retracting mechanism 23.

  As shown in FIG. 7B, when the transmission clutch 44 rotates, the plurality of expansion members 44a move outward in the radial direction against the urging force of the urging member 44c due to the centrifugal force applied to the weight portion 44b. Then, as shown in FIG. 8, the plurality of expansion members 44 a move outward in the radial direction, so that the plurality of expansion members 44 a come into contact with the friction surface 33 a of the driven member 33 of the retracting mechanism 23. Thereby, the rotational force is transmitted from the transmission clutch 44 to the driven member 33. That is, the transmission clutch 44 has a role as a centrifugal clutch.

  In this example, the example in which the transmission belt 47 that transmits the frictional force is used as an example of the transmission unit that transmits the rotational force from the driving roller 41 to the transmission clutch 44 is described, but the present invention is not limited thereto. As other examples of the transmission unit that transmits the rotational force, for example, various other configurations such as a chain and a gear may be used.

1-2. Next, the operation of the vibration suppression apparatus 20 will be described with reference to FIGS.
FIG. 9 is a side view showing a state in which the vibration suppressing device 20 has started to operate. 10 is a side view showing a state in which the operation of the vibration suppressing device 20 is completed, and FIG. 11 is an enlarged perspective view showing a main part of FIG.

  Here, since the lengths of the main rope 4 and the balancing rope 14 from the hoisting machine 8 always change while the car 3 is moving up and down, the natural period of the main rope 4 and the balancing rope 14 also changes. Therefore, the so-called resonance in which the swing period of the building structure coincides with the swing period of the main rope 4 and the balance rope 14 is difficult to continue, and the swing of the main rope 4 and the balance rope 14 is difficult to increase. Therefore, it is not necessary to suppress the swing of the main rope 4 or the balancing rope 14 while the car 3 is moving up and down.

  Further, since the first restraining member 21 and the second restraining member 22 of the shaking restraining device 20 project inside the track on which the car 3 travels (hereinafter referred to as “running track”), There exists a possibility that the 1st suppression member 21 and the 2nd suppression member 22 may contact.

  Accordingly, it is necessary to retract the first restraining member 21 and the second restraining member 22 in the swing restraining device 20 to the outside of the traveling track of the car 3 while the car 3 is moving up and down. In this example, the first restraining member 21 and the second restraining member 22 are retracted to the outside of the traveling track of the car 3 as follows.

  First, when the car 3 moves up and down (see FIGS. 12A and 12C), the governor rope 15 connected to the car 3 via the connection member 16 moves following the car 3. As shown in FIG. 9, the driving roller 41 of the transmission mechanism 24 is pressed against the return side rope 15 b of the governor rope 15. Therefore, the driving roller 41 is driven to rotate around the first transmission shaft 42 as the return side rope 15b moves.

  When the driving roller 41 is rotationally driven, the rotational force of the driving roller 41 is transmitted to the second transmission pulley 46 via the first transmission pulley 43 and the transmission belt 47. Then, the second transmission pulley 46 is driven to rotate about the second transmission shaft 45. Further, as shown in FIGS. 8 and 9, since the transmission clutch 44 is fixed to the second transmission pulley 46, the transmission clutch 44 is rotationally driven as the second transmission pulley 46 rotates.

  When the rotational speed of the transmission clutch 44 increases, the plurality of expansion members 44a and the plurality of weight portions 44b (see FIG. 7B) move outward in the radial direction against the urging force of the urging member 44c by centrifugal force. To do. Thereby, the length of the transmission clutch 44 in the radial direction is expanded. As shown in FIGS. 8 and 9, the plurality of expansion members 44 a of the transmission clutch 44 come into contact with the friction surface 33 a of the driven member 33 of the retracting mechanism 23. Thereby, the movement of the return side rope 15b is transmitted from the transmission mechanism 24 to the retracting mechanism 23 as a rotational force.

  When the rotational force is transmitted to the driven member 33, the driven member 33 and the first rotating shaft 31 fixed to the driven member 33 are allowed to have elastic force of the first support spring 25a and the second support spring 25b. Against this, the bearing part 32 (see FIG. 3) is rotated around the center. Therefore, the first suppression member 21 fixed to the first rotation shaft 31 also rotates as the first rotation shaft 31 rotates.

  Further, the rotational force of the first rotation shaft 31 is transmitted to the second rotation shaft 36 by the interlock mechanism 30 (see FIGS. 3 and 5). Therefore, the second rotation shaft 36 and the second suppression member 22 fixed to the second rotation shaft 36 rotate. As a result, the first restraining member 21 and the second restraining member 22 are rotated so that the restraining portion 26 is separated from the main rope 4 or the balancing rope 14.

  As shown in FIG. 10, when the driven member 33 rotates 90 degrees, the extension member 44 a of the transmission clutch 44 fits into the recess 33 b of the driven member 33 as shown in FIG. 11. And the expansion member 44a of the transmission clutch 44 and the rotating roller 33c provided in the recessed part 33b contact. Thereby, the rotational force of the transmission clutch 44 is transmitted to the rotation roller 33c, and the rotation roller 33c rotates. As a result, the driven member 33 is held in a state rotated 90 degrees from the state shown in FIG. That is, the first rotating shaft 31 fixed to the driven member 33 is also held in a state of being rotated 90 degrees. Further, the second rotation shaft 36 connected to the first rotation shaft 31 via the interlocking mechanism 30 is also held in a state of being rotated 90 degrees.

  When the first rotation shaft 31 and the second rotation shaft 36 rotate 90 degrees, the rotation arms 27 of the first suppression member 21 and the second suppression member 22 are connected to the wall surface of the hoistway 2. Move to a parallel state. As a result, the first restraining member 21 and the second restraining member 22 can be retracted out of the traveling track of the car 3, and can be held in a state of retracting out of the traveling track. As a result, the car 3 and the first restraining member 21 and the second restraining member 22 can be prevented from contacting each other, and the swing restraining device 21 does not hinder the traveling of the car 3.

  In this example, the example in which the driven member 33, the first rotation shaft 31, and the second rotation shaft 36 are rotated by 90 degrees has been described. However, it is not strictly limited to 90 degrees, What is necessary is just to retract | save the 1st suppression member 21 and the 2nd suppression member 22 out of the traveling track of the passenger car 3. Therefore, the angle at which the driven member 33, the first rotation shaft 31, and the second rotation shaft 36 are rotated may be less than 90 degrees or 90 degrees or more.

  Moreover, since the length from the hoisting machine 8 in the main rope 4 and the balance rope 14 does not change while the car 3 is stopped, the natural period of the main rope 4 and the balance rope 14 does not change. Therefore, the building structure, the main rope 4 and the balancing rope 14 may resonate, and the main rope 4 and the balancing rope 14 may swing greatly. Therefore, when the car 3 is stopped, it is necessary to suppress the shaking of the main rope 4 and the balancing rope 14 using the shaking suppressing device 20. In the present example, the main rope 4 and the balancing rope are projected as follows by causing the first restraining member 21 and the second restraining member 22 of the shaking restraining device 20 to protrude to the inside of the traveling track of the car 3. 14 vibrations are suppressed.

  First, when the car 3 stops, the governor rope 15 that moves following the raising / lowering operation of the car 3 also stops. Therefore, the rotation of the driving roller 41 stops and the rotation of the transmission clutch 44 also stops. When the rotation of the transmission clutch 44 stops, as shown in FIG. 7A, the plurality of expansion members 44a and the plurality of weight portions 44b are moved toward the second transmission shaft 45, that is, in the radial direction by the urging force of the urging member 44c. Move inward. As a result, as shown in FIGS. 3 and 6, the plurality of expansion members 44 a of the transmission clutch 44 are separated from the friction surface 33 a of the driven member 33, and a gap is formed between the transmission clutch 44 and the driven member 33. . As a result, transmission of power (rotational force) from the transmission mechanism 24 to the retracting mechanism 23 is interrupted.

  When the transmission force from the transmission mechanism 24 to the driven member 33 is interrupted, the rotating arm 27 is moved from the state parallel to the wall surface of the hoistway 2 by the restoring force of the first support spring 25a and the second support spring 25b. It rotates to a state orthogonal to the wall surface of the hoistway 2. As a result, the first rotation shaft 31 and the second rotation shaft 36 to which the rotation arm 27 is fixed rotate, and the driven member 33 also rotates to the state shown in FIG.

  Then, as shown in FIGS. 4 and 3, when the turning arm 27 of the first restraining member 21 and the second restraining member 22 is rotated until it becomes horizontal, the restraining portion 26 of the first restraining member 21 and The restraining portion 26 of the second restraining member 22 approaches or contacts the main rope 4 or the balancing rope 14. Thereby, the main rope 4 or the balancing rope 14 is clamped by the two suppression portions 26 and 26 of the first suppression member 21 and the second suppression member 22. Thereby, the swing of the main rope 4 or the balance rope 14 can be suppressed by the two suppression portions 26 and 26.

  Further, since the two restraining portions 26, 26 are brought close to or in contact with the main rope 4 or the balancing rope 14 and the swinging of the main rope 4 or the balancing rope 14 is restrained, the car 3 and the balancing weight 6. There is no need to constrain the vertical displacement. As a result, it is not necessary to increase the strength of the connecting portion between the car 3 and the main rope 4 or the balance rope 14 or increase the number of the main rope 4 and the balance rope 14.

  As described above, in the shake suppressing device 20 of this example, the governor rope 15 moves up and down the car 3 as power for retracting (turning) the first suppressing member 21 and the second suppressing member 22. The force generated when moving following the movement is used. In order to project the first restraining member 21 and the second restraining member 22 from the retracted state into the traveling track, the transmission force from the transmission mechanism 24 is mechanically interrupted and the first support spring is used. The restoring force of 25a and the second support spring 25b is used. Thereby, the 1st suppression member 21 and the 2nd suppression member 22 can be operated, without using the electronic components which operate | move using electricity, such as a motor, a control part, and a sensor, as a driving force.

[Relationship between the direction of raising / lowering the car and the direction of movement of the vibration control device]
Next, the relationship between the direction of the raising / lowering operation of the car 3 and the direction of the operation of the vibration suppressing device will be described with reference to FIG.
FIG. 12 is an explanatory diagram showing operations of the restraining members 21 and 22 of the car 3 and the shaking restraining device 20.

  As shown in FIG. 12A, when the car 3 moves toward the upper side T <b> 1, the connection side rope 15 a connected to the car 3 moves toward the same upper side T <b> 1 as the car 3. On the other hand, the return side rope 15b moves toward the lower side T2 opposite to the connection side rope 15a and the car 3. At this time, in this example, the first restraining member 21 and the second restraining member 22 of the shaking restraining device 20 are restrained around the first turning shaft 31 and the second turning shaft 36 from a horizontal state. The part 26 rotates in the first direction R1 facing upward.

  As shown in FIG. 12B, when the car 3 stops, the first restraining member 21 and the second restraining member 22 rotate in the second direction R2 from the retracted position.

  Next, as shown in FIG. 12C, when the car 3 moves toward the lower T2 from the position of the car 3 shown in FIG. 12B, the connection side rope 15a moves toward the same lower T2 as the car 3 To do. On the other hand, the return side rope 15b moves toward the upper side T1 opposite to the connection side rope 15a and the car 3. And the 1st suppression member 21 and the 2nd suppression member 22 have the suppression part 26 which is the direction opposite to 1st direction R1 centering on the 1st rotation axis | shaft 31 and the 2nd rotation axis | shaft 36. It rotates in the second direction R2 directed downward.

  Thus, the direction in which the first restraining member 21 and the second restraining member 22 rotate in accordance with the direction in which the car 3 moves changes. That is, when the car 3 moves toward the upper side T <b> 1, the first restraining member 21 and the second restraining member 22 rotate so that the restraining portion 26 faces in the same direction as the moving direction of the car 3. .

  When the rotation direction of the first restraining member 21 and the second restraining member 22 is opposite to the moving direction of the car 3, the first restraining member 21 and the second restraining member 22 are connected to the car 3. It will turn toward. Therefore, there exists a possibility that the 1st suppression member 21 and the 2nd suppression member 22 may contact.

  On the other hand, in this example, the first restraining member 21 and the second restraining member 22 are rotated in a direction away from the car 3. Thereby, it can prevent that the cage | basket | car 3 and the 1st suppression member 21 and the 2nd suppression member 22 contact during the retraction | saving operation | movement of the 1st suppression member 21 and the 2nd suppression member 22. FIG.

  In addition, according to the sway suppressing device 20 of the present example, even if the car 3 and the first suppressing member 21 and the second suppressing member 22 are in contact with each other, the impact force that is generated at the time of contact with the first suppressing member 21 and the 2nd suppression member 22 can be attenuate | damped by rotating. Furthermore, a damper may be provided in the first suppression member 21 and the second suppression member 22. Thereby, even if the 1st suppression member 21 and the 2nd suppression member 22 and the cage | basket | car 3 contact, the impact force generated at the time of contact can be attenuated.

Next, a modified example of the connecting member for connecting the governor rope 15 and the car 3 will be described with reference to FIG.
FIG. 13 is an explanatory view showing a modified example of the connecting member.

  Here, as shown in FIG. 3, in the above-described example, the connection member 16 that connects the connection side rope 15a and the car 3 is provided with a fixing hole 16a. And the connection side rope 15a is penetrated to this fixed hole 16a, and the connection member 16 and the connection side rope 15a are being fixed. As for a part of connection side rope 15a, the whole side part is covered with the connection member 16. FIG. Therefore, when the driving roller 41 of the transmission mechanism 24 is pressed against the connection side rope 15a, the connecting member 16 and the driving roller 41 come into contact with each other. Therefore, in the above-described example, the driving roller 41 needs to be pressed against the return side rope 15b to which the connecting member 16 is not fixed. However, according to the shape of the connecting member 16, the pressing of the driving roller 41 is not limited to the return side rope 15b.

  For example, as illustrated in FIG. 13, the connection member 16 </ b> B according to the modification has a hook-like fixing portion with the connection side rope 15 a. Therefore, a part of the side surface portion of the connection portion of the connection side rope 15a with the connection member 16B is exposed. Therefore, the driving roller 41 may be pressed against a part of the connection side rope 15a where the connection portion with the connection member 16B is exposed. Thereby, when the governor rope 15 moves, there is no possibility that the connecting member 16B and the driving roller 41 come into contact with each other.

  As shown in FIG. 13, when the driving roller 41 is pressed against the connection side rope 15a, the moving direction of the connection side rope 15a is opposite to that of the return side rope 15b. Therefore, when the rotational force is transmitted from the driving roller 41 to the transmission clutch 44, it is preferable to direct the rotation direction to the direction opposite to the driving roller 41.

It turns to the wall surface on one side in the short direction of the car 3 on the road 2.

  And when the 1st suppression member 51 and the 2nd suppression member 52 rotate from the state parallel to the wall surface of the hoistway 2 to a horizontal state, two bending parts 51a and 52b are the main rope 4 or fishing. The joint rope 14 is guided and moved between the first restraining member 51 and the second restraining member 52. Thereby, the swing of the main rope 4 or the balance rope 14 can be suppressed effectively.

  Since other configurations are the same as those of the vibration suppressing device 20 according to the first embodiment, description thereof will be omitted. Also with the vibration suppression apparatus 50 having such a configuration, the same operational effects as those of the vibration suppression apparatus 20 according to the above-described first embodiment can be obtained.

The second retraction mechanism 83 </ b> B is disposed on the other side in the longitudinal direction of the car 3 in the hoistway 2 and between the car 3 and the counterweight 6.

  The first retraction mechanism 83A has two first rotation shafts 91 and 91 and a follower member 93 formed in a fan shape. The two first rotation shafts 91 and 91 are rotatably supported by a support base 121 provided in the hoistway 2. The two first rotation shafts 91 and 91 are provided parallel to each other and parallel to the vertical direction along the traveling track of the car 3.

  Further, the first driving roller 101a and the second driving roller 101b are pressed against the return side rope 15b. The first driving roller 101a and the first transmission pulley 103a are connected by a so-called one-way clutch that transmits rotational force only in one direction. Similarly, the second driving roller 101b and the second transmission pulley 103b are connected by a one-way clutch. The first driving roller 101a transmits the rotational force to the first transmission pulley 103a only when the return side rope 15b moves downward T2. Further, the second driving roller 101b transmits the rotational force to the second transmission pulley 103b only when the return side rope 15b moves upward T1.

  A first transmission belt 107a is stretched around the first transmission pulley 103a and the third transmission pulley 104 in an open belt shape, so-called parallel hanging. Therefore, the first transmission pulley 103a and the third transmission pulley 104 rotate in the same direction. Further, a second transmission belt 107b is stretched around the second transmission pulley 103b and the third transmission pulley 104 in a so-called cross shape. Therefore, the second transmission pulley 103b and the third transmission pulley 104 rotate in opposite directions.

  As a result, the third transmission pulley 104 always rotates only in the direction of the arrow S1 regardless of whether the return side rope 15b moves upward T1 or downward T2.

  As shown in FIG. 15, the transmission mechanism 54 includes a fourth transmission pulley 106 that is rotatably supported by the third transmission shaft 105, a third transmission belt 111, a fifth transmission pulley 108, 4 transmission belts 112, a sixth transmission pulley 109, and a transmission clutch 110. The fourth transmission pulley 106 is fixed to the third transmission pulley 104 and rotates together with the third transmission pulley 104.

  The fifth transmission pulley 108 is rotatably supported by the fourth transmission shaft 108a. The fourth transmission shaft 108 a is disposed in parallel with the vertical direction along the traveling track of the car 3. A third transmission belt 111 is stretched between the fourth transmission pulley 106 and the fifth transmission pulley 108.

  The fourth transmission shaft 108a is rotatably provided with a first interlocking pulley 99A that constitutes an interlocking mechanism. The first interlocking pulley 99A rotates together with the fifth transmission pulley 108. A fourth transmission belt 112 is stretched between the first interlocking pulley 99A and the sixth transmission pulley 109. The sixth transmission pulley 109 is provided with a transmission clutch 110. Since the configuration of the transmission clutch 110 is the same as that of the transmission clutch 44 according to the first embodiment, the description thereof is omitted.

  The interlocking mechanism 90 includes a first interlocking pulley 99A and a second interlocking pulley 99B. An interlocking belt 98 is stretched around the first interlocking pulley 99A and the second interlocking pulley 99B in an X shape, so-called a cross. The second interlocking pulley 99B is rotatably supported by the support base 123. The support base 123 is provided with a fifth transmission belt 114, a seventh transmission pulley 115, and a transmission clutch 110 having the same configuration as the fourth transmission belt 112, the sixth transmission pulley 109, and the transmission clutch 110. It has been. The configuration of the fifth transmission belt 114, the seventh transmission pulley 115, and the transmission clutch 110 is the same as that of the fourth transmission belt 112, the sixth transmission pulley 109, and the transmission clutch 110, and a description thereof will be omitted. To do.

  In the vibration suppressing device 80 according to the third embodiment, when the car 3 moves up and down, the force generated when the return rope 15b moves is transmitted via the transmission mechanism 84 and the interlocking mechanism 90 to the first. This is transmitted to the driven member 93 of the retracting mechanism 83A and the second retracting mechanism 83B.

  As shown in FIG. 16, when the rotational force is transmitted, the driven member 93, the first rotation shaft 91, the second rotation shaft 96, and the rotation arm 87 are connected to the first support spring 85A and It rotates horizontally around a bearing (not shown) against the elastic force of the second support spring 85B. The rotating arm 87 approaches the wall surfaces on both sides of the car 3 in the hoistway 2 in the longitudinal direction from the center of the traveling track of the car 3. At this time, the restraining portion 86 and the pair of turning arms 87 are turned and folded by the turning pins 86b. That is, the first suppressing member 81 and the second suppressing member 82 constitute a parallel link mechanism. As a result, the first restraining member 81 and the second restraining member 82 are retracted to the outside of the traveling track of the car 3.

  When the car 3 stops, the transmission clutch 110 is separated from the driven member 93, so that the rotational force is cut off. Then, the pair of rotating arms 87 of the first suppressing member 81 and the second suppressing member 82 is changed from the state shown in FIG. 16 to the state shown in FIG. 15 by the elastic force of the first supporting spring 85A and the second supporting spring 85B. It rotates horizontally to the state shown in. At this time, since the bent portion 86 a is provided in the suppressing portion 86, the main rope 4 or the balancing rope 14 is guided, and the suppressing portion 86 of the first suppressing member 81 and the suppressing portion of the second suppressing member 82 are guided. 86. As a result, the main rope 4 or the balancing rope 14 is sandwiched between the restraining portion 86 of the first restraining member 81 and the restraining portion 86 of the second restraining member 82, and the shaking thereof is restrained.

  Since other configurations are the same as those of the vibration suppressing device 20 according to the first embodiment, description thereof will be omitted. Also with the vibration suppression device 80 having such a configuration, it is possible to obtain the same operational effects as those of the vibration suppression device 20 according to the first embodiment described above.

  Further, as shown in the vibration suppressing device 80 according to the second embodiment and the vibration suppressing device 20 according to the first embodiment described above, the direction in which the rotating arm is rotated is set in various ways. It is what is done.

Therefore, here, the vibration suppressing device will be described, and portions common to the elevator 1 according to the first embodiment are denoted by the same reference numerals, and redundant description is omitted.

  The vibration suppression devices 20, 50, and 80 according to the first to third embodiments described above are those in which the suppression member is rotated and retracted out of the traveling track. On the other hand, the vibration suppression apparatus 200 according to the fourth embodiment is configured to retract the suppression member and retract it from the traveling track.

  As illustrated in FIG. 18, the shaking suppression device 200 includes a suppression member 201, a retracting mechanism 207, a transmission mechanism 208, a support spring 206 that indicates a support mechanism, and a not-shown interlocking mechanism.

  The restraining member 201 is fixed vertically to the wall surface of the hoistway 2. And the suppression member 201 is arrange | positioned horizontally. The restraining member 201 includes a first pipe member 202, a second pipe member 203, a third pipe member 204, and a fourth pipe member 205 that are slidably connected to each other. .

  The first pipe member 202 is configured by a cylindrical body. The second pipe member 203 is made of a cylindrical body having a diameter larger than that of the first pipe member 202, and the third pipe member 204 is made of a cylindrical body having a diameter larger than that of the second pipe member 203, and The pipe member 205 is formed of a cylindrical body having a diameter larger than that of the third pipe member 204.

  The fourth pipe member 205 is a first-stage pipe member that is the outermost part, and one end in the axial direction thereof is fixed to the wall surface of the hoistway 2. The third pipe member 204 can be accommodated in the tube hole 205a of the fourth pipe member 205 in a nested state. Further, the second pipe member 203 can be accommodated in the cylindrical hole 204a of the third pipe member 204 in a nested state. The first pipe member 202 can be accommodated in the cylinder hole 203a of the second pipe member 203 in the inserted state.

  Protrusions 202b, 203b, and 204b projecting outward in the radial direction are provided at one axial end portions of the first pipe member 202, the second pipe member 203, and the third pipe member 204, respectively. In addition, inner flange portions 203c, 204c, and 205c projecting radially inward are provided at the openings on the other end side in the axial direction of the second pipe member 203, the third pipe member 204, and the fourth pipe member 205. It has been.

  The protrusions 202b, 203b, and 204b abut against the inner flange portions 203c, 204c, and 205c, thereby restricting the first pipe member 202, the second pipe member 203, and the third pipe member 204 from falling off.

  Further, contact portions 203d and 204d are provided in the cylindrical holes 203a and 204a on one end side in the axial direction of the second pipe member 203 and the third pipe member 204, respectively. The contact portions 203d and 204d are inner flanges that project inward in the radial direction.

  The first pipe member 202 is a final-stage pipe member that is the innermost part. The opening of the other axial end of the first pipe member 202 is closed. A restraining portion 202 c that approaches or contacts the main rope 4 or the balancing rope 14 is attached to the other end portion of the first pipe member 202 in the axial direction. One end of a wire member 212 of a retracting mechanism 207, which will be described later, is attached to the suppressing portion 202c.

  A support spring 206 is accommodated in the cylindrical holes 202a, 203a, 204a, and 205a of the first pipe member 202, the second pipe member 203, the third pipe member 204, and the fourth pipe member 205. Yes. One end of the support spring 206 is fixed to the wall surface of the hoistway 2, and the other end of the support spring 206 is fixed to the other axial end of the first pipe member 202. The support spring 206 urges the first pipe member 202, the second pipe member 203, and the third pipe member 204 in a direction away from the wall surface of the hoistway 2.

  In addition, the suppressing member (not shown) having the above-described configuration is disposed so as to face the suppressing member 201 with the main rope 4 or the balancing rope 14 interposed therebetween.

  The retraction mechanism 207 includes a rotating shaft 211, a wire member 212, and a driven roller 213 that indicates a driven member. The rotating shaft 211 is rotatably supported by a bearing (not shown). One end of the wire member 212 in the axial direction is fixed to the suppressing portion 202 c of the first pipe member 202, and the other end of the wire member 212 in the axial direction is fixed to the rotating shaft 211. The driven roller 213 is attached to the rotating shaft 211. Then, the driven roller 213 rotates together with the rotating shaft 211.

  The transmission mechanism 208 includes a driving roller 221, a first transmission shaft 222, a first transmission pulley 223, a transmission clutch 224, a second transmission shaft 225, a second transmission pulley 226, and an endless shape. A transmission belt 227. Since the configuration of the transmission mechanism 208 is the same as that of the transmission mechanism 208 according to the first embodiment described above, description thereof is omitted.

  In addition, although the suppression member 201 concerning this 4th Embodiment demonstrated the example comprised from four pipe members 202, 203, 204, 205, the number of the pipe members which comprise the suppression member 201 is four. It is not limited to one. For example, the suppression member 201 may be configured by three or less, or five or more pipe members.

  When the car 3 moves up and down, the transmission clutch 224 of the transmission mechanism 208 is rotationally driven by the moving force of the return rope 15b that follows the car 3 as shown in FIG. Then, when the transmission clutch 224 and the driven roller 213 come into contact with each other, the moving force of the return side rope 15b is transmitted to the retracting mechanism 207 through the transmission mechanism 208 as a rotational force.

  When the rotational force is transmitted to the driven roller 213, the rotation shaft 211 rotates. As the rotating shaft 211 rotates, the wire member 212 is wound around the rotating shaft 211. Then, the first pipe member 202 of the suppression member 201 moves in a direction approaching the wall surface of the hoistway 2 against the elastic force of the support spring 206. When the first pipe member 202 moves along the cylindrical hole 203 a of the second pipe member 203, one end in the axial direction of the first pipe member 202 contacts the contact portion 203 d of the second pipe member 203. . As a result, the second pipe member 203 moves into the cylindrical hole 204 a of the third pipe member 204 together with the first pipe member 202.

  When the second pipe member 203 moves along the cylindrical hole 204 a of the third pipe member 204, one end in the axial direction of the second pipe member 203 abuts against the contact portion 204 d of the third pipe member 204. Touch. Thereby, the 1st pipe member 202, the 2nd pipe member 203, and the 3rd pipe member 204 move in the cylinder hole 205a of the 4th pipe member 205 in one.

  Further, the first pipe member 202 is accommodated in the second pipe member 203, and the second pipe member 203 is accommodated in the third pipe member 204. Further, the third pipe member 204 is accommodated in the fourth pipe member 205. As a result, the restraining member 201 is retracted out of the traveling track of the car 3 by contracting.

  When the suppressing member 201 contracts, the driven roller 213 rotates idly with a predetermined torque applied to the rotating shaft 211. Thereby, the contracted state of the suppressing member 201 can be maintained.

  When the car 3 is stopped, the transmission clutch 224 is separated from the driven roller 213, and the rotational force that drives the retracting mechanism 207 is cut off. The first pipe member 202 is biased toward the main rope 4 or the balancing rope 14 by the restoring force of the support spring 206. Therefore, the first pipe member 202 moves along the cylindrical hole 203 a of the second pipe member 203. Then, the projection 202 b of the first pipe member 202 contacts the inner flange portion 203 c of the second pipe member 203, and the second pipe member 203 moves together with the first pipe member 202.

  Further, as the second pipe member 203 moves, the projection 203 b of the second pipe member 203 comes into contact with the inner flange portion 204 c of the third pipe member 204. As a result, the first pipe member 202, the second pipe member 203, and the third pipe member 204 are urged by the support spring 206 and project into the traveling track of the car 3. Then, the protrusion 204b of the third pipe member 204 comes into contact with the inner flange portion 205c of the fourth pipe member 205, whereby the extension operation of the suppressing member 201 is completed. As a result, the restraining member 201 extends from the contracted state shown in FIG. 19 to the state shown in FIG. 18, and the restraining portion 202 c approaches or contacts the main rope 4 or the balancing rope 14.

  Since other configurations are the same as those of the vibration suppressing device 20 according to the first embodiment, description thereof will be omitted. Also with the vibration suppression apparatus 200 having such a configuration, it is possible to obtain the same operational effects as those of the vibration suppression apparatus 20 according to the above-described first embodiment.

For example, in the embodiment described above, an example in which only one shaking suppression device is arranged in the hoistway has been described. However, the present invention is not limited to this, and a plurality of shaking restraining devices are arranged in the hoistway. May be.

  Moreover, in order to prevent the restraining part from coming into contact with the car 3, the shaking restraining device is installed at a position where the car 3 does not stop. Therefore, the vibration suppressing device of the present invention is suitable for a rope-type shuttle elevator that stops only on two floors in a building structure, for example, the top floor and the bottom floor.

  Further, in the above-described embodiment, the example using the rotation mechanism and the expansion / contraction mechanism as the retraction mechanism has been described. However, the retraction mechanism may be configured by combining a rotation mechanism and an expansion / contraction mechanism.

  Furthermore, although the example using the movement of the governor rope 15 used for the governor 10 as the driving force of the retracting mechanism has been described, the present invention is not limited to this. As the driving force of the retracting mechanism, the movement of the rope following the raising / lowering operation of the car 3 is used. For example, as a driving force for the retracting mechanism, a rope that follows the lifting and lowering operation of the car 3 and the counterweight 6 may be provided exclusively.

  In the above-described embodiment, the main rope 4 and the balancing rope 14 are applied as an example of the long body disposed in the hoistway 2, and the swinging of the main rope 4 and the balancing rope 14 is suppressed. However, the present invention is not limited to this example. The vibration suppressing device of the present invention can be applied to suppress the vibration of various other long bodies such as a governor rope and a tail cord disposed in the hoistway 2.
