Is equipped with. The hoisting device 2 is configured to be movable with respect to the structure 80, and thus the sheave 3 is movable with respect to the structure 80.

The elevator 1 includes a vibrating device 40 that applies an external force to the hoisting device 2 to vibrate the hoisting device 2, and elastic bodies 51 and 52 that apply an external force to the hoisting device 2 by elastic restoring force. There is. Further, the elevator 1 includes a switching unit 60 that switches the hoisting device 2 between a fixed state and a movable state with respect to the structure 80. The switching unit 60 includes a plurality (four in the present embodiment) of fixing devices 61 that fix the hoisting device 2 to the structure 80.

The structure 80 includes a frame 81 that constitutes a building (for example, a hoistway, a machine room), and a rail 82 that is fixed to the frame 81. Further, the structure 80 includes a base portion 83 fixed to the skeleton 81 in order to fix each component (for example, the vibration device 40, the elastic bodies 51 and 52, the fixing device 61) to the skeleton 81. There is. The skeleton 81 shown in FIGS. 1 and 2 (not shown in FIG. 3) is the floor (foundation) of the machine room arranged directly above the hoistway.

The rail 82 extends along the first direction D1. The hoisting device 2 (the sheave 3) is movable in the first direction D1 with respect to the structure 80. In other words, the hoisting device 2 (the sheave 3) is movable with respect to the rail 82 in the direction in which the rail 82 extends (also referred to as “rail direction”) D1. In the present embodiment, the rail 82 is a T-shaped rail, but the rail 82 is not limited to such a configuration and may be, for example, a groove rail or a step rail.

The hoisting device 2 includes a sheave driving unit (for example, an electric motor) 4 that rotates the sheave 3, a sheave supporting unit 5 that rotatably supports the sheave 3, and a pulley 6 on which the rope 30 is hung. ing. Further, the hoisting device 2 is arranged between the upper frame 7 supporting the sheave 3, the lower frame 8 arranged below the upper frame 7, and the upper frame 7 and the lower frame 8 in the vertical direction. , And a support frame 9 for supporting the upper frame 7 on the lower frame 8.

The hoisting device 2 includes a traveling unit 10 that travels on the structure 80 while being in contact with the structure 80. Specifically, the traveling unit 10 travels on the rail 82 along the first direction D1 while being in contact with the rail 82. The traveling unit 10 includes a rolling element 11 that is in contact with the upper portion of the structure 80 (rail 82) and can roll. In the present embodiment, the rolling element 11 is a disk-shaped roller that rotates around a second direction D2 that is orthogonal to the first direction D1.

The elastic bodies 51 and 52 elastically deform in the first direction D1. As a result, the elastic bodies 51 and 52 apply an external force in the first direction D1 to the hoisting device 2 by the elastic restoring force. In the present embodiment, the elastic bodies 51 and 52 are coil-shaped springs that elastically deform in the first direction D1.

The first and second elastic bodies 51, 52 are arranged so as to sandwich a part of the hoisting device 2 in the first direction D1. The inner end portions (inner end portions in the first direction D1) 51a and 52a of the first and second elastic bodies 51 and 52 are fixed to the hoisting device 2 by being connected to the lower frame 8. ing. Further, the outer end portions (outer end portions in the first direction D1) 51b and 52b of the first and second elastic bodies 51 and 52 are connected to the base portion 83, so that the structure body 80 (rail 82) is It is fixed.

As a result, in the state where the external force is not applied to the hoisting device 2, the hoisting device 2 has the structure 80 (rail 82) at a position where the elastic restoring forces of the first and second elastic bodies 51 and 52 are balanced. Stop against. Therefore, the hoisting device 2 returns to the initial position without any particular adjustment. Each of the first and second elastic bodies 51 and 52 is always elastically deformed so as to be compressed in the first direction D1 regardless of the position of the hoisting device 2 with respect to the structure 80 (rail 82). ..

And a movable body 42 that can be moved. In the present embodiment, the vibration device 40 is a hydraulic piston device, but is not limited to such a configuration.

The vibrating device 40 also connects the movable body 42 to the gravity center position of the hoisting device 2 so as to apply an external force to the gravity center position (specifically, the gravity center position in the second direction D2). Thereby, the external force from the vibrating device 40 can be stably applied to the hoisting device 2. In addition, in the present embodiment, the movable body 42 is connected to the lower frame 8 of the hoisting device 2.

Then, the movable body 42 reciprocates in the first direction D1 with respect to the device main body 41, whereby external forces in one direction and the other direction of the first direction D1 are alternately and repeatedly applied to the hoisting device 2. .. As a result, the hoisting device 2 reciprocates (vibrates) in the first direction (also referred to as “movement direction” or “vibration direction”) D1 with respect to the structure 80 (rail 82).

By the way, each of the 1st and 2nd elastic bodies 51 and 52 has the same spring constant. Then, the hoisting device 2 has not only the natural frequencies of the first and second elastic bodies 51 and 52 (the frequency that is completely the same as the natural frequency but also the frequency that is ±10% of the natural frequency). (Including) is vibrating. As a result, the hoisting device 2 resonates, so that the external force that the vibration device 40 should apply to the hoisting device 2 can be reduced.

The hoisting device 2 can move with respect to the structure 80 (rail 82) by, for example, 10 mm or more, preferably 10 mm to 100 mm, and more preferably 30 mm to 50 mm. Further, the hoisting device 2 moves with respect to the structure 80 (rail 82) by, for example, 1% or more, preferably 1% to 10%, and more preferably 3% to 5% of the diameter of the sheave 3. be able to.

Therefore, conventionally, it was not possible to actually reproduce the shaking of the earthquake, and it was designed by a desk calculation, but by moving (vibrating) the hoisting device 2 with respect to the structure 80 in this way, Since the shaking of an earthquake can be reproduced, more accurate design can be performed.

Next, the configurations of the upper frame 7, the lower frame 8, the support frame 9, and the traveling unit 10 will be described.

As shown in FIGS. 3 and 4, the upper frame 7 includes a pair of first upper frame members 7a, 7a extending along the first direction D1 and a pair of second upper frame members extending along the second direction D2. 7b, 7b. The lower frame 8 also includes a pair of first lower frame members 8a, 8a extending along the first direction D1 and a pair of second lower frame members 8b, 8b extending along the second direction D2. ..

The support frame 9 includes a pair of support frame members 9a and 9a extending along the first direction D1 with respect to one first lower frame member 8a. In addition, the support frame 9 includes an outer connecting portion 9b that connects the outside of each support frame member 9a in the first direction D1 and the first lower frame member 8a, and the inside of each support frame member 9a in the first direction D1 and the first connecting member 9a. 1 inner frame 9c for connecting the lower frame member 8a.

The upper portion of the supporting frame member 9a is connected to the lower portion of the upper frame 7 (specifically, the second upper frame member 7b), and the connecting portions 9b and 9c are the lower portion of the supporting frame member 9a and the lower frame 8 respectively. (Specifically, the upper portion of the first lower frame member 8a) is connected. As a result, the load applied to the upper frame 7 is dispersed by the plurality of connecting portions 9b and 9c and is received by the first lower frame member 8a. As the load applied to the upper frame 7, for example, the sheave 3 on which the load of the car 31 and the counterweight 32 (not shown in FIGS. 3 and 4) is applied via the rope 30, and the sheave. The load of the drive part 4 etc. is mentioned.

The traveling unit 10 includes a holding unit 12 that rotatably holds the rolling element 11. The holding portion 12 is connected to the lower portion of the lower frame 8 (specifically, the first lower frame member 8a). Since the traveling unit 10 has the plurality of rolling elements 11 arranged in parallel in the first direction D1, the load received by the first lower frame member 8a is received by the plurality of rolling elements 11. In the present embodiment, the traveling unit 10 has the five rolling elements 11 arranged in parallel in the first direction D1.

By the way, in the first direction D1, the outer end position P1 where the first lower frame member 8a receives a load from the support frame 9 (that is, the outer end position of the outer connecting portion 9b) P1 is the outermost rolling element 11. It is located outside the rotation center position P2. As a result, a load is sufficiently applied to the rolling element 11 arranged on the outermost side, so that the rolling element 11 can be prevented from floating on the rail 82.

Further, the rolling element 11 arranged in the center receives the load from both the supporting frame members 9a, 9a. Therefore, in the first direction D1, the rotation center position P3 of the rolling element 11 arranged at the center is the inner end position where the first lower frame member 8a receives a load from each of the support frame members 9a, 9a (that is, the inner connecting portion). It is located between the inner end position 9c) P4 and P4.

As a result, it is possible to prevent an excessive load from being applied to the rolling element 11 arranged in the center. The plurality of rolling elements 11 are arranged so that the loads received by them are equal. Therefore, the distances W1 to W4 between the rotation center positions of the rolling elements 11 are different from each other.

As shown in FIGS. 4 and 5, the traveling unit 10 includes a separation prevention unit 13 that is in contact with a side portion of the rail 82 in order to prevent the rolling element 11 from separating from the rail 82. The separation prevention unit 13 includes a rotating body 13 a that rotates in contact with the side portion of the rail 82, and a rotation supporting unit 13 b that rotatably supports the rotating body 13 a and is fixed to the holding unit 12. The rolling element 11 is provided with a protruding portion 11 a that can protrude in the radial direction and come into contact with the side portion of the rail 82, and the protruding portion 11 a also has a function as the separation preventing portion 13.

A plurality (two in the present embodiment) of the traveling units 10 are arranged in parallel with respect to one first lower frame member 8a in the second direction D2. That is, a plurality of (in the present embodiment, two) rails 82 are arranged in parallel with respect to one first lower frame member 8a.

As a result, a plurality of rolling elements 11 are arranged in parallel not only in the first direction D1 but also in the second direction D2 with respect to one first lower frame member 8a. Therefore, since the load received by the first lower frame member 8a is received by the plurality of rolling elements 11 (in this embodiment, 10), the load bearing performance (eg, size) of each rolling element 11 is large. ) Can be made smaller.

Next, the configuration of the vibration device 40 will be described.

As shown in FIG. 6, the vibration device 40 includes a vibration drive unit (for example, a pump) 43 that supplies a pressure medium (oil in the present embodiment) to the device body 41 in order to operate the movable body 42. And a valve (for example, an electromagnetic valve) 44 that switches between supplying and stopping the pressure medium. Then, the vibration drive unit 43 and the valve 44 cause the movable body 42 to reciprocate in the first direction D1 with respect to the apparatus body 41.

By the way, when a power failure occurs while the hoisting device 2 is vibrating, the valve 44 closes, while the hoisting device 2 moves from the elastic bodies 51 and 52 (not shown in FIG. 6). It vibrates continuously due to external force applied. As a result, the movable body 42 moves with respect to the apparatus body 41, and the pressure of the pressure medium locked by the valve 44 increases, which may cause the vibration device 40 (for example, the valve 44) to malfunction.

Therefore, the vibration device 40 includes a power supply device 45 for supplying electric power to the valve 44 at the time of power failure. This prevents the vibration device 40 from breaking down during a power failure. The power supply device 45 supplies electric power to a fixed detection unit 71 (not shown in FIG. 6, see FIGS. 7 to 9) when the power failure occurs, and the hoisting device 2 causes the switching unit 60 (not shown). 6 (not shown in FIG. 6), electric power may be supplied to the valve 44 when the movable state with respect to the structure 80 is detected.

Next, the configuration of the fixing device 61 of the switching unit 60 will be described.

As shown in FIGS. 7 and 8, the fixing device 61 includes a main body portion 62 fixed to the base portion 83, a fixing portion 63 for fixing the hoisting device 2, an operated operation portion 64, and a fixing portion 63. And the operating portion 64, and a connecting portion 65 that is screwed into the main body portion 62. Then, by operating the operating portion 64, the fixing portion 63 moves with respect to the main body portion 62, and at the same time, the hoisting device 2 (specifically, the end portion of the first lower frame member 8 a of the lower frame 8). ) To move.

As a result, in the fixing device 61, as shown in FIG. 7, the fixing portion 63 moves away from the hoisting device 2 to release the fixing of the hoisting device 2, and as shown in FIG. By contacting the hoisting device 2, the state in which the hoisting device 2 is fixed is switched. In the present embodiment, the fixing portion 63 is formed in a tapered shape and is fitted into the hole 8c of the lower frame 8 to fix the moving device 2.

In this way, when the fixing device 61 releases the fixing of the hoisting device 2, the hoisting device 2 becomes movable with respect to the rail 82 (not shown in FIGS. 7 and 8). Become. On the other hand, when the fixing device 61 fixes the hoisting device 2, the hoisting device 2 is fixed to the rail 82.

The elevator 1 includes a fixing detection unit 71 that detects a state in which the fixing device 61 fixes the hoisting device 2 and a state in which the fixing device is released. In the present embodiment, the fixation detection unit 71 is a contact sensor that contacts the operation unit 64 of the fixation device 61. Then, the fixation detection unit 71 is arranged in each of the fixation devices 61.

Further, the elevator 1 includes a movement detection unit 72 that detects that the hoisting device 2 has moved with respect to the rail 82 by a predetermined distance or more (the hoisting device 2 is located at an abnormal position). In the present embodiment, the movement detector 72 is a photoelectric sensor. The movement detector 72 shields the hoisting device 2 (specifically, the end portion of the first lower frame member 8a of the lower frame 8) when the hoisting device 2 is located at the normal position. The hoisting device 2 is arranged so as not to be shielded from light when the hoisting device 2 is located at the abnormal position.

Next, a configuration related to control of the elevator 1 will be described. In the following description, there are configurations not shown in FIG. 9, but it is not specified that they are not shown in FIG.

As shown in FIG. 9, the elevator 1 is arranged in each of the halls, the vibration input section 73 into which the vibration information is input, the car input section 74 arranged inside the car 31, and the car input section 74 into which the information is inputted. , And a hall input unit 75 to which information is input. In the present embodiment, the vibration input unit 73 is arranged near the hoisting device 2, for example, inside the machine room.

The vibration input unit 73 includes a driving input unit 73a to which information for selecting the normal driving mode and the vibration mode (test mode) is input, and a vibration condition of the hoisting device 2 (e.g., amplitude, frequency (frequency of vibration). A condition input section 73b for inputting information such as frequency). Further, the vibration input unit 73 includes a vibration input unit 73c to which information on the start and stop of vibration is input.

Further, the elevator 1 is arranged in each of the halls and the vibration output unit 76 that outputs vibration information and the car output unit 77 that is arranged inside the car 31 and that outputs information. And a landing output section 78. In the present embodiment, the vibration output unit 76 is arranged near the hoisting device 2, for example, inside the machine room.

Further, the elevator 1 includes a control unit 70 that controls the vibration device 40 based on the information input to the vibration input unit 73. Then, the control unit 70 controls the vibrating device 40 so that the hoisting device 2 vibrates at the natural frequency of the elastic bodies 51 and 52, unless information on a specific frequency is input by the condition input unit 73b. .. The control unit 70 controls each unit 4, 40, 76 to 78 based on the information input from each unit 71 to 75.

And the control part 70 which concerns on this embodiment performs the following controls, for example. The control of the elevator 1 is not limited to such control.

When the information for selecting the vibration mode is input to the operation input unit 73a, the control unit 70 controls the sheave drive unit 4 based on the information already input to the car input unit 74 and the hall input unit 75. .. Then, after the control based on the information ends, the control unit 70 controls the sheave driving unit 4 so that the car 31 is located at a predetermined position (for example, the lowest floor position).

When information is input to the car input unit 74 and the hall input unit 75 after the information for selecting the vibration mode is input to the operation input unit 73a, the control unit 70 determines, based on the information, that the sheave The drive unit 4 is not controlled. Then, for example, when information is input to the car input unit 74, the control unit 70 outputs information to the effect that the sheave drive unit 4 is not controlled to the car output unit (eg, display device, audio device) 77. Further, for example, when information is input to the hall input unit 75, information indicating that the sheave drive unit 4 is not controlled is output to the hall output unit (eg, display device, audio device) 78.

Further, since all the fixing detection units 71 detect the release of the fixing of the hoisting device 2 and the relevant information is input from all the fixing detection units 71, the control unit 70 can operate in the vibration mode. To As a result, it is possible to prevent the driving in the vibration mode when at least one fixing device 61 fixes the hoisting device 2. The control unit 70 causes the vibration output unit (for example, the display device) 76 to output information that allows the driving in the vibration mode, for example.

Further, all the fixing detection units 71 detect the fixing of the hoisting device 2, and the information is input from all the fixing detection units 71, so that the control unit 70 enables the operation in the normal operation mode. .. Accordingly, it is possible to prevent the at least one fixing device 61 from being operated in the normal operation mode while the hoisting device 2 is released from being fixed. The control unit 70 causes, for example, the vibration output unit (for example, the display device) 76 to output information that enables the operation in the normal operation mode.

As described above, in the hoisting device 2 according to the present embodiment, the sheave 3 on which the rope 30 connected to the car 31 and the counterweight 32 is hung, and the sheave 3 moves with respect to the structure 80. In addition, the rolling element 11 capable of rolling in contact with the structure 80 is provided.

Further, the elevator 1 according to the present embodiment includes the hoisting device 2 having the sheave 3 on which the rope 30 connected to the car 31 and the counterweight 32 is hung, and the rail 82 fixed to the skeleton 81. The hoisting device 2 includes a rolling element 11 that is in contact with the rail 82 and can roll in order to move the sheave 3 relative to the rail 82.

According to this structure, the rolling element 11 rolls in contact with the structure 80 (rail 82), so that when the sheave 3 moves relative to the structure 80 (rail 82), the structure 80 (rail 82) is moved. 82), the frictional force generated in the hoisting device 2 can be reduced. Thereby, for example, the external force to be applied to the hoisting device 2 in order to move the sheave 3 with respect to the structure 80 (rail 82) becomes small, or the sheave 3 with respect to the structure 80 (rail 82). You can move smoothly.

Further, the elevator 1 according to the present embodiment is arranged so as to sandwich at least a part of the hoisting device 2 in the direction D1 in which the rail 82 extends, and is elastically deformed in the direction D1 in which the rail 82 extends. Two elastic bodies 51 and 52 are provided, and inner end portions 51a and 52a of the first and second elastic bodies 51 and 52 are fixed to the hoisting device 2, and the first and second elastic bodies are provided. The outer ends 51b and 52b of the respective 51 and 52 are fixed to the rail 82.

According to such a configuration, the first and second elastic bodies 51, 52 are arranged so as to sandwich the hoisting device 2 in the direction D1 in which the rail 82 extends, and elastically deform in the direction D1 in which the rail 82 extends. The inner end portions 51a and 52a of the first and second elastic bodies 51 and 52 are fixed to the hoisting device 2 and the outer ends of the first and second elastic bodies 51 and 52 are respectively fixed. The ends 51b and 52b are fixed to the rail 82.

Thereby, for example, when the hoisting device 2 reciprocates (vibrates) with respect to the rail 82, the elastic restoring force of the first and second elastic bodies 51, 52 can be utilized. Further, for example, when the application of the external force to the hoisting device 2 is stopped, the hoisting device 2 moves relative to the rail 82 at a position where the respective elastic restoring forces of the first and second elastic bodies 51 and 52 are balanced. It is easy to return the hoisting device 2 to the initial position because it is stopped.

Further, the elevator 1 according to the present embodiment is a coil-shaped spring that elastically deforms in the direction D1 in which the rail 82 extends, and has one end portions 51a and 52a fixed to the hoisting device 2 and the other end portion 51b. , 52b fixed to the rail 82, and a vibrating device for applying an external force to the hoisting device 2 so as to vibrate the hoisting device 2 in the direction D1 in which the rail 82 extends. 40, and a control unit 70 that controls the vibrating device 40 such that the hoisting device 2 vibrates at the natural frequency of the elastic bodies 51 and 52.

According to such a configuration, the elastic bodies 51 and 52 are coil-shaped springs that elastically deform in the direction D1 in which the rail 82 extends. Further, one ends 51 a and 52 a of the elastic bodies 51 and 52 are fixed to the hoisting device 2, and the other ends 51 b and 52 b of the elastic bodies 51 and 52 are fixed to the rail 82. ..

Then, the vibrating device 40 vibrates the hoisting device 2 in the direction D1 in which the rail 82 extends by applying an external force to the hoisting device 2, and the control unit 70 causes the hoisting device 2 to move the elastic body 51,. The vibrating device 40 is controlled so as to vibrate at the natural frequency of 52. This makes it possible to reduce the external force to be applied to the hoisting device 2 when the hoisting device 2 reciprocates (vibrates) with respect to the rail 82.

In addition, the elevator 1 according to the present embodiment is configured to include a switching unit 60 that switches the hoisting device 2 between a fixed state and a movable state with respect to the rail 82.

According to such a configuration, the switching unit 60 switches between the state in which the hoisting device 2 is fixed to the rail 82 and the state in which the hoisting device 2 is movable with respect to the rail 82. Thus, for example, when reproducing the shaking of an earthquake, the hoisting device 2 is movable with respect to the rail 82, and during normal operation, the hoisting device 2 is fixed with respect to the rail 82. By doing so, the elevator 1 can be used both for testing and for practical use.

The hoisting device 2 and the elevator 1 are not limited to the configurations of the above-described embodiments, and are not limited to the above-described operational effects. Further, it goes without saying that the hoisting device 2 and the elevator 1 can be variously modified without departing from the scope of the present invention. For example, it is needless to say that one or a plurality of configurations and methods according to the various modifications described below may be arbitrarily selected and used for the configurations and methods according to the above-described embodiments.
