Field of the Invention The present invention relates to a system for shifting a movable hammer that is supported in a freely displaceable state by a movable chamber to reduce vibration of a cabin. The vibrating device, more specifically, relates to a technique for improving the vibration damping device to effectively reduce the vibration of the cabin. Φ [Prior Art] As shown in Fig. 7, the passenger compartment 1 of the elevator has the cabin 4 supported by the vibration insulator 3 on the frame 2, and the main cable 5 suspended from the hoisting machine (not shown) is passed through the vibration insulator 6 It is connected to the frame 2 and is raised and lowered inside the lifting path 7. Further, the guide roller 9 supported by the vibration insulator 8 at the upper and lower four corners of the frame 2 is rotated on the pair of right and left guide rails V〇L, 10R which are attached to the wall surface 7a of the elevation path 7 and then extend in the vertical direction. Guide the boarding • Lifting of the car 1. At this time, since the guide rails L, L, and 10R are slightly bent, the laterally oscillating force of the passenger compartment 1 that moves up and down in the hoistway 7 acts via the guide roller 9. This oscillating force can be attenuated to some extent by the vibration insulator 8 and the vibration insulator 3 before being transmitted to the chamber 4, but cannot be completely blocked, and is removed from the guide rails l〇L, 10R. Bending, a large number of workmanships are required for its installation and adjustment. -4 - 1290532 ' (2)

Therefore, a lateral direction of the cabin 4 is proposed. A vibration damping device that attenuates vibration and improves ride comfort (for example, refer to Patent Document 1 below). The vibration damping device 12 shown in Fig. 7 has a rolling bevel screw 1 4 fixed to the bottom of the chamber 4 and driven to rotate in the forward and reverse directions by the driving motor 13; screwing on the ball screw 1 a movable hammer 15 that is displaced back and forth in the direction of the axis thereof; and a control means 17 that controls the action of the drive motor 13 based on a signal obtained from the accelerometer 16 fixed to the cabin 4, thereby being movable The inertial force obtained by the forced displacement of the hammer 15 is used to eliminate the vibration generated by the cabin 4, and the ride comfort is improved. [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei 5-310386 (Invention) Solution to Problem] However, in the above-described conventional vibration damping device 12, the signal output from the accelerometer 16 also includes the vibration component generated by the wind that is shaken by the wind. Therefore, the control means 17 also eliminates the accompanying housing construction. Shaking the generated vibration component drives the movable hammer 15. However, when the building is shaken on a high floor and in a soft structure, it is a very low frequency (0.5 Ηζ or less), and its displacement is also a few hundred mm. 1290532 ' (3) ' Therefore, in order to eliminate such a vibration component, the mass of the movable hammer 15 must be set very large, or the displacement stroke of the movable hammer 15 must be set very large, thus causing the vibration damping device The size of 1 2 is large. Moreover, from the viewpoint of vibration resistance, the relative displacement between the guide rails l〇L, l0R and the passenger compartment 2 is several mm, and the shaking of the building is outside the corresponding range of the vibration damping device, and the building itself will shake. Therefore, there is no need to correspond. Φ Moreover, the vibration which causes a problem when the vibration of the cabin 4 is reduced to improve the riding comfort is the vibration insulator 8 attached to the guide roller 9, and the vibration insulator interposed between the frame 2 and the compartment 4. The vibration of the low-level natural frequency among the three. Therefore, unnecessarily expanding the frequency of the vibration to be oscillated by the vibration damping device 12 not only causes an increase in the size of the vibration damping device 12 but also a vibration-damping efficiency in the frequency domain required for vibration suppression. reduce. Further, when the high-frequency vibration or the like of the drive motor _ 13 generated in the vibration damping device 12 is transmitted to the cabin 4, the ride comfort in the cabin 4 is deteriorated. In addition, when foreign matter intrudes into the movable portion of the ball screw 14 or the like from the outside, the device deteriorates, and the smooth operation is hindered, resulting in a reduction in the vibration-damping action. Accordingly, an object of the present invention is to solve the problems of the above-described prior art and to provide a lifting mechanism vibration device which can effectively suppress vibration generated in a cabin and improve riding comfort in the cabin. 1290532 * (4) - [Means for Solving the Problem] The first-stage lifting mechanism for solving the above problem is provided in the front vibrating device by suppressing vibration generated in the cabin of the elevator; The elevator includes: a guide rail supporting the lifting and lowering of the frame of the cabin, and a guiding means; and the guiding means and the Φ first vibration insulating means; and the vibration damping The device has: a movable hammer that supports the moving state in the chamber; and a displacement of the movable hammer to be driven; and a vibration for measuring vibration generated by the chamber and a signal obtained from the vibration measuring means a means for frequency domain of a low-level natural frequency of the first vibration insulating means; and means for controlling the operation of the segment based on a signal by the filtering means. Φ In addition, the filtering method can combine low-pass filters and high-pass. That is, the first-stage lifting mechanism vibrating device is for the signal obtained by the vibration measuring means, and only the signal of the frequency domain of the low-level natural frequency of the packet insulating means is exchanged for the lower layer including the first vibration insulating means. Filtering means is used to reduce the gain of the frequency domain of the sub-natural frequency. Therefore, in order to suppress the vibration between the guide rail and the frame due to the frequency of the first vibration insulating means, the concentrated vibration device is a system for the cabin; and the synergy between the frame and the frame is possible. The driving means for measuring the free position; filtering the driver filter including the signal to make the first vibration of the accelerometer is for the low-level inherent use of the movable hammer -7-1290532 ' (5) And driving means. Therefore, the vibration damping capability of the movable hammer and the driving means can be limited to reduce the weight and size, and the mass of the entire passenger compartment can be reduced, and the electric power required to operate the driving means can be reduced. Further, the hoisting and lowering vibration device of the second aspect for solving the above-described problems is a vibration damping device provided in the cabin for suppressing vibration generated in a cabin of the elevator, and is characterized in that: U: the elevator includes: And supporting a second vibration insulating means between the car frame and the cab; and the vibration damping device has a movable hammer supported in the chamber to be freely displaceable And a driving means for driving the movable hammer to displace the vibration; and a vibration measuring means for measuring the vibration generated by the chamber; and the signal obtained from the vibration measuring means, including the second vibration insulating means The filtering means of the signal in the frequency domain of the low-level natural frequency; and the control means for controlling the operation of the driving hand segment based on the signal by the filtering means. Further, the filtering means can be used by combining a low pass filter and a high pass filter. In other words, the second-stage lifting mechanism vibration device is a signal obtained from a frequency domain including a low-level natural frequency of the second vibration insulating means among signals obtained by a vibration measuring device such as an accelerometer, in other words, in order to make The filtering means is used to reduce the gain in the frequency domain other than the frequency domain including the low-level natural frequency of the second vibration insulating means. Therefore, in order to suppress the vibration between the frame and the cabin due to the low-level inherent -8-1290532 (6) frequency of the second vibration insulating means, the driving means can be integrated. Therefore, the weight of the vibration-damping type of the movable hammer and the driving means can be limited, so that the mass of the passenger compartment can be reduced, and the electric power required for the operation can be reduced. Further, the third aspect for solving the above-described problems is a vibration damping device for suppressing a vibration φ chamber generated in a cabin of an elevator, and is characterized in that the cabin is supported in a freely displaceable state. a driving means for shifting the movable hammer; and a vibration measuring means for measuring the generated vibration; and a signal obtained from the vibration to remove the filtering means for setting the frequency component provided with the elevator; The filtering means controls the control means of the operation of the driving means. Further, as the filtering means, a combination of a notch type filter, a φ high-pass filter, or the like can be used. That is, the third-stage lifting mechanism vibrating means is a signal obtained by an equal vibration measuring means, and the low-level natural frequency component of the building is removed, in other words, the filtering means is used for the gain of the layer-specific natural frequency component. Therefore, it is not necessary to operate the driving means to reduce the displacement stroke of the hammer in order to suppress the low-level natural frequency component in the vibration of the cabin, and the weight of the movable hammer can be reduced, and the vibration device can be reduced in size to reduce the driving means. The use of the movable hammer capability to reduce the size of the moving hammer is provided for the purpose of vibrating the driving mechanism; and the signal low-pass filter for driving the low-level fixed-wave means measured by the cabin dynamic measuring means and The construction of the house included in the low-rise building from the accelerometer is reduced, and the power required for the entire system can be reduced. -9- 1290532 • (7) Further, in the first to third aspect of the hoisting mechanism, at least the movable hammer and the driving means may be attached to the chamber by a third vibration insulating means. Thereby, it is possible to prevent the high-frequency vibration generated by the driving means and the like from being transmitted to the cabin, so that the noise in the cabin can be reduced and the riding comfort can be improved. Further, in the first to third aspect of the hoisting and lowering mechanism, at least the movable hammer and the driving means may be sealed, and the casing may be attached to the front φ to be freely detachable. Thereby, it is possible to prevent dust or the like from adhering to the precision movable parts included in the driving means and the like, and to prevent the high-frequency vibration generated by the driving means and the like from propagating through the air. Further, it is only necessary to remove the sealing means during the inspection, and it is not necessary to remove the entire device having the weight, so that the maintenance can be easily performed. Further, in the first to third aspect of the lifting mechanism vibration device, it is further provided that frequency analysis is performed on the signal obtained from the vibration measuring means, and then the low-level natural frequency of the building in which the elevator is installed is provided. a frequency analysis calculation unit that performs the calculation; and a display unit for displaying the low-level natural frequency of the building that is obtained by the calculation. Therefore, the signal obtained from the vibration measuring means enters the control means without passing through the filtering means, and then processed by the frequency analyzing arithmetic unit, and displayed on the display, the number of natural vibrations of the house building can be known. Therefore, it is not necessary to prepare another measuring device in order to know the natural vibration number of the house. Moreover, since the natural vibration number of the building can be directly known, the adjustable 10- (8) 1290532 control means that the action of the control means is formed in an optimum state, and a good damping effect can be obtained. [Effect of the Invention] As apparent from the above description, according to the present invention, it is possible to provide a lifting mechanism vibration device which can effectively suppress the vibration generated in the cabin and improve the riding comfort in the cabin.

In the following description, the same reference numerals are used in the same portions, and the overlapping description will be omitted. First, referring to Fig. 1, when the structure of the elevator to which the vibration damping device according to the first embodiment is applied is described, the passenger compartment 1 has a compartment supported by the vibration insulator (second vibration insulator) 3 on the frame 2. The chamber 4, Φ and the main cable 5 suspended from a hoisting machine (not shown) are connected to the frame 2 via the vibration insulator 6, and are moved up and down inside the lifting path 7. Further, the guide roller 9 that supports the upper and lower four corners of the frame 2 via the vibration insulator (first vibration insulator) 8 is a pair of right and left guide rails that are attached to the wall surface 7a of the elevation path 7 and then extend in the vertical direction. , 10R rotates, and guides the lifting and lowering of the passenger compartment 2. Further, in order to attenuate the lateral vibration of the cabin 4 and improve the riding comfort, the vibration damping device 20 is attached to the bottom of the cabin 4. The vibration damping device 20 has a fixing member 2 1 fixed to the cabin 4 as shown in Fig. 2, a bottom surface, and a vibration insulator (third vibration insulator) 2 2 supported by This frame 2 3 on the fixing member 2 1 . Further, the screw 24 which is supported by the left and right vertical walls 23a and 23b of the frame 23 and which is rotatable in the left and right direction, and then extends in the left-right direction of the drawing can be made by the drive motor 25 provided on the vertical wall 23b on the right side of the drawing. It rotates in both forward and reverse directions. Further, the movable hammer 26 is screwed to the screw 24, and is displaceable in the left-right direction of the drawing by the rotation of the screw 24 0. In addition, an accelerometer (vibration measuring means) 27 is provided in the cabin 4 for measuring the vibration generated by the cabin 4 and outputting it to the control means 28 °. In the control means 28, as shown in Fig. 3 As shown in the schematic diagram, the acceleration signal 31 input from the accelerometer 27 is subjected to processing via the low pass filter 32, the high pass filter 33, the notch type filter 34, the integrator 35, and the amplifier 36, and is input to the adder 3 7. φ On the other hand, the hammer position signal 3 obtained from the hammer position sensor (not shown) is input to the adder 3 7 after being processed by the hammer position signal control operation unit 39, and the obtained movable hammer is obtained. The thrust command signal is output as a result to the drive motor 25. Further, in Fig. 3, the filters (filter means) are connected in series, but the types of filters used may be changed as needed or connected in parallel. In addition, in the gain map shown in Fig. 4, the symbol 41 is a low-pass filter, 42 is a high-pass filter, and 43 is an interrupting characteristic of the notch type filter -12-1290532 - (10) • The gain map It can be understood that among the signals input from the accelerometer 27, the gain of the low-level natural frequency component with respect to the building with the elevator is lowered. Further, the gain in the frequency domain other than the frequency domain including the low-level natural frequencies of the first and second vibration insulating means 8 and 3 is lowered. That is, in the vibration damping device 20 of the present embodiment, the acceleration signal 31 passing through the notch type filter 34 does not include the φ low-level natural frequency component of the house building in which the elevator is installed. Therefore, the control means 28 does not operate the drive motor 25, and oscillates the low-level natural frequency component of the building house included in the vibration of the cabin 4, so that the displacement stroke of the movable hammer 26 can be set small. The vibration damping device 20 is downsized, and the electric power required to operate the drive motor 25 can be reduced. Further, in the vibration damping device 20 of the present embodiment, the acceleration signal 31 passing through the low-pass filter 321 and the high-pass filter 33 mainly includes the #vibration insulator (first vibration insulator) 8 and the guide rails 10L and 10R. The frequency component of the vibration generated between the cells 2 and the frequency component of the vibration generated between the frame 2 and the frame 2 by the natural frequency of the vibration insulator (second vibration insulator) 3. Therefore, in order to suppress the vibration generated in the cabin 4, the movable hammer 26 and the drive motor 25 can be collectively used. Therefore, the movable hammer 26 and the drive motor 25 can be made smaller and lighter, so that the mass of the cabin 4 can be reduced, and the electric power required to operate the drive motor 25 can be reduced. -13- 1290532 (11) Further, Fig. 5 shows a housing (sealing means) 50 in which the vibration damping device 20 is housed and sealed. The casing 50 has a box-shaped main body portion 5 1 that is fixed to the bottom surface of the cabin 4 and houses the vibration damping device 20, and a lid body 52 that can be detachably opened and closed by opening and closing the lower portion of the main body portion, and The cover 52 is fixed to the structure of the main body portion by the bolts 53. Therefore, it is possible to prevent dust or the like from adhering to the precision movable parts of the screw 24 and the electric motor φ machine 25 or the like, and to prevent the high-frequency vibration generated by the drive motor 25 or the like from being transmitted to the inside of the cabin 4 via the air. Further, it is only necessary to remove the cover body 5 2 during the inspection, and it is not necessary to remove the entire vibration damping device 20 having the weight, so that the maintenance can be easily performed. Further, Fig. 6 shows the function of the vibration damping device 20, and the acceleration signal 61 obtained from the accelerometer 27 attached to the cabin 4 does not pass through each filter but is directly input to the frequency of the control means 28. The calculation unit 62 is analyzed. In this manner, the frequency analysis calculation unit 62 calculates the natural vibration number of the house in which the elevator is installed by processing the acceleration signal 61, and displays it on the display unit 63. Therefore, it is not necessary to prepare another measuring device in order to know the natural vibration number of building a house, and the setting of the control means 28 can be adjusted on the spot, and the operation of the control means 28 can be optimally matched with the natural vibration number of the house building. Therefore, good vibration damping can be achieved.
