[0017]
As shown in FIG. 1, the elevator rope steadying device 30 according to the present embodiment includes an oblique turning arm 40, a tilting arm 50, and a rope shake restraining fixing member 60. In this case, the oblique turning arm 40 and the tilting arm 50 are disposed substantially in the middle in the height direction on the lifting or lowering track of the riding rod 13.
[0018]
FIG. 2 is an enlarged perspective view of the oblique turning arm 40 and the tilting arm 50. As shown in FIGS. 1 and 2, a turning drive shaft 41 is disposed outside one side (left side in FIG. 1) of the lifting / lowering track of the riding rod 13. The axis of the turning drive shaft 41 is oriented at an angle of 45 degrees with respect to the vertical direction. As shown in FIG. 2, the turning drive shaft 41 is supported by a clutch horizontal shaft 43 having a clutch mechanism 43 a that can be connected and released via a turning drive means 42. The clutch horizontal shaft 43 is supported by an intermediate beam or an elevator guide rail (not shown).
[0019]
The clutch mechanism 43a is connected in a state where the tilting arm 50 is orthogonal to the lifting or lowering track of the riding rod 13 by a link bar 43b connected to the tilting arm 50 described later (see FIG. 3). Is released when parallel to (see FIG. 2). The position and posture holding force acts on the clutch horizontal shaft 43 when the clutch mechanism 43a is connected, and the position and posture holding force is released when the clutch mechanism 43a is released. Yes.
[0020]
The oblique turning arm 40 is supported by the turning drive shaft 41 and is directed from the outside of the lifting or lowering track of the riding rod 13 toward the ideal orbit of the main rope 12 above the riding rod 13 or the compensation rope 15 below the riding rod 13. It rotates until it is substantially orthogonal to the ideal trajectory. In this case, since the axis of the turning drive shaft 41 is inclined 45 degrees, the inclined turning arm 40 has a conical surface shape from a state substantially parallel to the ascending / descending track of the riding rod 13 (see FIG. 2). Is rotated to a state (see FIG. 4) that is substantially orthogonal to the lifting or lowering track of the riding rod 13 (see FIG. 3).
[0021]
The drive of the turning drive shaft 41 is controlled based on the state of the riding rod 13 by the turning control unit 42 c and the turning drive means 42 connected to the elevator control device 20.
[0022]
In the present embodiment, the pre-turning position sensor 46a that detects that the oblique turning arm 40 is substantially parallel to the raising / lowering trajectory of the riding rod 13 (see FIG. 2), and the oblique turning arm 40 raises / lowers the riding 13 A post-turn position sensor 46b (see FIG. 4) for detecting that the vehicle is substantially orthogonal to the track is provided.
[0023]
And the elevator control apparatus 20 (riding rod control part) restrict | limits the raising / lowering control of the riding rod 13 based on the detection result of the position sensor 46a before turning and the position sensor 46b after turning.
[0024]
Specifically, for example, only when it is detected by the pre-turn position sensor 46a that the oblique turning arm 40 is in a state of being substantially parallel to the lifting or lowering trajectory of the riding rod 13, the vicinity of the inclined turning arm 40 is placed in the vicinity of the lean turning arm 40. Can pass through.
[0025]
The oblique turning arm 40 is formed of a substantially cylindrical bar. However, in order to perform the hand movement without damaging the main rope 12 or the compensation rope 15, it is sufficient that the area that can contact the rope is smoothly chamfered.
[0026]
Further, a counterweight 47 having a weight that is substantially balanced with the oblique turning arm 40 with the turning drive shaft 41 as a fulcrum is provided on the opposite side of the oblique turning arm 40 around the turning drive shaft 41.
[0027]
On the other hand, as shown in FIGS. 1 and 2, a tilt drive shaft 51 is disposed outside the front surface (the back side in FIG. 1) of the elevating orbit of the riding rod 13. The axis of the tilt drive shaft 51 faces the horizontal direction orthogonal to the vertical direction. The tilt drive shaft 51 is pivotally supported by an intermediate beam or an elevator guide rail (not shown). As shown in FIG. 2, the tilt drive shaft 51 is supported by a drive means 53 having a clutch mechanism 53a that can be connected and released.
[0028]
The clutch mechanism 53a is connected in a normal state, and is released when an excessive torque load is applied to the tilt drive shaft 51. The tilt drive shaft 51 is adapted to have its position / posture holding force when the clutch mechanism 53a is connected, and is released when the clutch mechanism 53a is released. Yes.
[0029]
The tilt arm 50 is supported by the tilt drive shaft 51 and is in a state (see FIGS. 3 and 4) that is substantially perpendicular to the lift track of the ride 13 from a state that is substantially parallel to the lift track of the ride 13 (see FIG. 2). (See)).
[0030]
The tilt arm 50 is formed with a concave portion 50r from the side far from the tilt drive shaft 51 (the front side in FIG. 1) so that it does not interfere with the ideal trajectory of the main rope 12 or the compensation rope 15 during its rotation. Has been.
[0031]
In this case, the recess 50r is constituted by a tapered portion 50t and a square portion 50s. The square portion 50 s is formed to be slightly larger than the cross-sectional area of the main rope 12 or the compensation rope 15. But the recessed part 50r may be comprised by the general V shape or U shape.
[0032]
The drive of the tilt drive shaft 51 is controlled based on the state of the ride 13 by the tilt control unit 53 c and the drive means 53 connected to the elevator control device 20. Then, the slant turning arm 40 is controlled so as to pull the main rope 12 or the compensation rope 15 toward the concave portion 50r of the tilt arm 50 rotated to a state substantially orthogonal to the lifting or lowering track of the riding rod 13. The main rope 12 or the compensation rope 15 is guided toward the intended trajectory.
[0033]
In the present embodiment, the pre-tilt position sensor 56a that detects that the tilt arm 50 is substantially parallel to the lifting or lowering trajectory of the riding rod 13 (see FIG. 2), and the tilt arm 50 is A post-turn position sensor 56b that detects that the vehicle is in a state substantially orthogonal to the ascending / descending track is provided (see FIG. 4).
[0034]
And the elevator control apparatus 20 (riding rod control part) restrict | limits the raising / lowering control of the riding rod 13 based on the detection result of the position sensor 56a before tilting, and the position sensor 56b after tilting.
[0035]
Specifically, for example, only when it is detected by the pre-tilt position sensor 56a that the oblique turning arm 40 is in a state substantially parallel to the lifting or lowering trajectory of the riding rod 13, the vicinity of the tilting arm 50 is climbed. 13 is allowed to pass.
[0036]
The recess 50r of the tilt arm 50 is formed by a substantially cylindrical bar. However, in order to assist the manual movement of the oblique turning arm 40 without damaging the main rope 12 or the compensation rope 15, it is sufficient that the area that can contact the rope is smoothly chamfered.
[0037]
Further, on the opposite side of the tilt arm 50 with respect to the tilt drive shaft 51, a counterweight 57 having a weight substantially balanced with the tilt arm 50 is provided with the tilt drive shaft 51 as a fulcrum.
[0038]
Further, as shown in FIG. 1, an annular rope run-out restraining fixing member 60 surrounding the lifting track is provided outside the lifting track of the riding rod 13. In this case, the rope run-out suppressing fixing member 60 is provided at a substantially intermediate position between the hoisting machine 11 and the tilt drive shaft 51 in the height direction and a substantially intermediate position between the lower sheave 16 and the tilt drive shaft 51. It has been.
[0039]
The rope run-out restraining fixing member 60 has at least the shape of the lifting / lowering track side of the riding rod 13 in an arc shape or smooth so as not to damage the ropes when coming into contact with the main rope 12 or the compensation rope 15. It is preferable to be chamfered.
[0040]
Further, as shown in FIG. 1, the elevator control device 20 of the present embodiment controls (stops or decelerates) the riding board 13 based on the input information.
[0041]
Then, the tilt control unit 53c connected to the elevator control device 20 drives the tilt drive shaft 51 based on the input information so that the tilt arm 50 is substantially orthogonal to the lifting track of the riding rod 13. It is designed to rotate.
[0042]
Further, the turning control unit 42 c connected to the elevator control device 20 drives the turning drive shaft 41 based on the input information to turn the turning arm 40 in a state substantially orthogonal to the lifting or lowering track of the riding rod 13. It is like that.
[0043]
Here, the input information is weather information such as a strong wind warning or a strong wind warning. That is, when a strong wind warning or a strong wind warning is issued, the elevator ropes 12 and 15 are predicted to swing in advance. The elevator ropes 12 and 15 are prevented from being shaken by appropriately rotating and carrying out the hand-feeding operation.
[0044]
Alternatively, the input information may be ambient environment information obtained from an anemometer or a seismometer. That is, when the measured wind speed is greater than or equal to a predetermined value or when a vibration (earthquake) greater than or equal to the predetermined value is observed, the elevator ropes 12 and 15 are expected to swing, so the riding 13 is decelerated. In addition to the mode, the tilting arm 50 and the oblique turning arm 40 are appropriately rotated to carry out the hand pulling operation, and the elevator ropes 12 and 15 are steady.
[0045]
Alternatively, the input information may be management judgment information based on judgment criteria uniquely set by a building manager or an elevator management company. That is, when it is determined that the hand-drawn movement by the tilting arm 50 and the oblique turning arm 40 should be performed based on a predetermined determination criterion, the riding rod 13 is set in the deceleration operation mode and the tilting arm is moved. The elevator ropes 12 and 15 are prevented from swinging by appropriately rotating the 50 and the oblique turning arm 40.
[0046]
Alternatively, the input information may be rope shake detection information obtained from rope shake detection means or the like. That is, when a swing of the elevator ropes 12 and 15 is actually detected, the riding rod 13 is set to the deceleration operation mode, and the tilting arm 50 and the oblique turning arm 40 are appropriately rotated to perform the hand-drawing operation. It carries out and the steady rest of the elevator ropes 12 and 15 is implemented.
[0047]
An example of the rope shake detection means will be described with reference to FIG. The rope shake detecting means 70 shown in FIG. 5 includes a first projector 71 that projects light passing through a first detection point α at a predetermined distance δ from the ideal trajectory of the main rope 12 or the compensation rope 15, and a first projector 71. And a first light receiver 72 that receives light emitted from the first light receiver 72.
[0048]
Further, the rope shake detecting means 70 projects light from the second projector 73 that projects light passing through the second detection point β that is shifted by a predetermined distance in the height direction from the first detection point α, and the second projector 73. And a second light receiver 74 for receiving the light to be transmitted.
[0049]
The first light receiver 72 and the second light receiver 74 are connected to a discriminator 75 (discrimination unit). The discriminator 75 discriminates the rope shake and outputs the rope shake detection information when the first light receiver 72 and the second light receiver 74 detect the light blocking state at the same time.
[0050]
In this way, by setting the two detection points α and β, it is possible to prevent erroneous detection due to the passage of floating objects or small birds.
[0051]
In order to prevent erroneous detection due to rain or the like, it is preferable to employ a combination of a light projector and a light receiver that is not determined to be light-shielded by the intervention of about five sheets of paper.
[0052]
As other rope shake detection means, a monitoring camera that monitors the state of the main rope 12 or the compensation rope 15 can be used. For example, as shown in FIG. 1, the monitoring cameras 80 a and 80 b can be installed at the lower part of the floor surface that supports the hoisting machine 11 or the lower part of the riding board 13. The images obtained by the monitoring cameras 80a and 80b can be used for determining the swing of the rope through various image processing operations.
[0053]
Next, the operation of the present embodiment having such a configuration will be described.
[0054]
During normal operation, the tilting arm 50 and the oblique turning arm 40 are each in a state parallel to the ascending / descending track of the riding rod 13 (see FIG. 2). The elevator 13 is controlled by the elevator control device 20 (riding controller) to move the elevator 13 up and down, open and close the entrance door, and the like.
[0055]
When input information such as the weather information, the surrounding environment information, the management judgment information, or the rope shake detection information as described above is input to the elevator control device 20, the elevator control device decelerates or stops the ride 13. The riding rod 13 is reliably retracted from the vicinity of the oblique turning arm 40 and the tilting arm 50.
[0056]
Next, the drive means 53 is driven by the tilt control unit 53c, the tilt drive shaft 51 is rotated, and the tilt arm 50 is in a state orthogonal to the lifting track of the riding rod 13 (see FIG. 3). . At this time, since the clutch mechanism 53a is connected, the position and orientation of the tilt arm 50 are maintained in this state.
[0057]
As shown in FIG. 3, the clutch mechanism 43 c is connected by a link bar 43 b connected to the tilt arm 50. Accordingly, the position and orientation of the clutch horizontal shaft 43 is maintained. That is, a posture holding force is applied so that the angle of the turning drive shaft 41 (45 degrees oblique to the vertical direction) is maintained.
[0058]
In this state, the turning drive unit 42 is operated by the turning control unit 42c, and the turning drive shaft 41 rotates. Along with this, the oblique turning arm 40 supported by the turning drive shaft 41 passes through a conical surface locus (see FIG. 3) from a state parallel to the raising / lowering orbit of the riding rod 13 (see FIG. 2). Rotate to a state (FIG. 4) perpendicular to the lifting or lowering trajectory of the riding rod 13.
[0059]
As a result, the oblique turning arm 40 pulls the main rope 12 or the compensation rope 15 toward the concave portion 50r of the tilting arm 50 rotated to a state substantially orthogonal to the lifting or lowering track of the riding rod 13. Thereby, the main rope 12 or the compensation rope 15 is guided along the ideal trajectory, and an effective steadying is realized. At this time, the tapered portion 50t of the concave portion 50r effectively assists the hand-pulling movement of the ropes 12 and 15 to the square portion 50s by the oblique turning arm 40.
[0060]
The recesses 50r (regions in which the rope can come into contact) of the oblique turning arm 40 and the tilting arm 50 are formed by a substantially cylindrical bar, so that the hand rope movement or the compensation rope 15 is not damaged. It can be performed.
[0061]
Moreover, the counterweight 47 provided on the oblique turning arm 40 and the balance weight 57 provided on the tilting arm 50 cause the rotational movement of the oblique turning arm 40 and the tilting arm 50 to be performed smoothly.
[0062]
Once the hand-pulling movement of the rope has been carried out, the inclined turning arm 40 and the tilting arm 50 are allowed in order to allow the passage (the vicinity of the inclined turning arm 40 and the tilting arm 50) of the ride 13 to pass. Are rotated in the opposite directions, and returned to the state parallel to the ascending / descending track of the riding rod 13 again (see FIG. 2).
[0063]
When it is detected by the pre-turn position sensor 46a and the pre-tilt position sensor 56a that the oblique turn arm 40 and the tilt arm 50 are in a state substantially parallel to the lifting or lowering track of the ride 13, the elevator control device 20 It is determined that the part 13 can pass through the ride 13.
[0064]
Due to an abnormality in the control system, for example, when the riding arm 13 tries to pass through the portion when the tilting arm 50 and the oblique turning arm 40 are orthogonal to the lifting or lowering trajectory of the riding rod 13, the inertia of the riding rod 13 is obtained. Since the moving force strongly pushes up (or pushes down) the tilt arm 50 and the link bar 43b, the clutch mechanism 53c and the clutch mechanism 43a are released, and the tilt arm 50 and the clutch horizontal shaft 43 become free, and the ride 13 Pushes the tilting arm 50 and the oblique turning arm 40 and passes through the part.
[0065]
Here, in order to reduce the impact of the fall of the tilt arm 50 that has become free, it is preferable to provide an impact buffer 53s as shown in FIG.
[0066]
The clutch mechanism 43a is preferably automatically released when the riding rod 13 pushes up (or pushes down) the oblique turning arm 40 strongly. And it is preferable that an appropriate shock absorbing device is provided in order to reduce the impact of the fall of the inclined swing arm 40 that has become free.
[0067]
On the other hand, the rope run-out restraining fixing material 60 acts so as to restrain large run-out of the main rope 12 and the compensation rope 15. As shown in FIG. 1, if there is no rope run-out restraining fixing member 60, there is a possibility that the run-out of the rope may remain to the extent shown by the broken line A even when the tilting arm 50 and the turning arm 40 pull the rope. Due to the presence of the rope run-out suppressing fixing member 60, the run-out of the rope can be suppressed to the extent indicated by the two-dot chain line B.
[0068]
This effect is that the rope run-out restraining fixing material 60 is provided at a substantially intermediate position between the hoisting machine 11 and the tilt drive shaft 51 and a substantially intermediate position between the lower sheave 16 and the tilt drive shaft 51. Sometimes noticeable.
[0069]
But the number of arrangement | positioning of the tilting arm 50 and the turning arm 40, and the number of arrangement | positioning of the rope runout suppression fixing material 60 can be suitably determined according to the specification of the elevator apparatus 10. FIG. Of course, the rope run-out restraining fixing material 60 cannot be provided at the entrance 21.
[0070]
For example, when two sets of the tilt arm 50 and the swivel arm 40 are provided with respect to the lifting / lowering trajectory of one riding rod 13, as shown in FIG. 6, three rope shake suppression fixing members 60 can be provided. .
[0071]
As a preferable arrangement relationship, as shown in FIG. 6, the three rope vibration suppression fixing members 60 are provided with the tilt drive shaft 51 and the second tilt drive for the tilt arm 50 and the second tilt arm 50 ′. With respect to the shaft 51 ′, a substantially intermediate position between the hoisting machine 11 and the tilt drive shaft 51, a substantially intermediate position between the tilt drive shaft 51 and the second tilt drive shaft 51 ′, the lower sheave 16 and the first It can be provided at a substantially intermediate position with respect to the two tilt drive shaft 51 '.
[0072]
Alternatively, when three sets of the tilt arm 50 and the turning arm 40 are provided with respect to the lifting or lowering track of one riding rod 13, four rope runout suppression fixing members can be provided as shown in FIG.
[0073]
As a preferable positional relationship, as shown in FIG. 7, three annular rope runout restraining fixing members 60 are provided for the tilt arm 50, the second tilt arm 50 ′, and the third tilt arm 50 ″. With respect to the rolling drive shaft 51, the second tilt driving shaft 51 ′, and the third tilt driving shaft 51 ″, a substantially intermediate position between the hoisting machine 11 and the tilt driving shaft 51, and the tilt driving shaft 51 and the third tilt driving shaft 51 ″. It can be provided at a substantially intermediate position between the second tilt drive shaft 51 ′ and a substantially intermediate position between the second tilt drive shaft 51 ′ and the third tilt drive shaft 51 ″. A U-shaped rope run-out suppressing fixing member 60 ′ may be provided at a position between the third tilt drive shaft 51 ″ and closer to the third tilt drive shaft 51 ″.
[0074]
Here, the wind force is reduced on the lower floor of the outdoor observation elevator. Therefore, the U-shaped rope run-out suppressing fixing member 60 between the downward sheave 16 and the third tilting drive shaft 51 ″ can be omitted.
[0075]
The shape of the rope run-out suppressing fixing material is not limited to an annular shape or a U-shape, and various shapes can be adopted as long as they are effective in suppressing rope run-out.
[0076]
6 and 7, reference numerals 91 to 95 are retreat floors. As shown in FIGS. 6 and 7, it is preferable that the tilt arm 50 and the swing arm 40 are provided on the floor in the vicinity of the floor set as the retreat floor. This will be described.
[0077]
In general, in the case of an outdoor observation elevator that reciprocates between the observation floor and the lowermost floor, evacuation floors (emergency rescue floors) are set at several locations along the hoistway. A door device is installed on the floor of the retreat floor. Further, since the riding board 13 stops at the evacuation floor in an emergency, a sensor or the like for detecting landing of the riding board 13 is installed on the evacuation floor.
[0078]
Thereby, since there are incidental facilities such as a door device and various sensors, there is a high possibility that the elevator rope will be tangled in the vicinity of the retreat floor compared to other floors. Therefore, it is preferable that the tilt arm 50 and the swing arm 40 are provided on the floor near the floor set as the retreat floor.
[0079]
For example, in the case of a 40th floor building, the retreat floor can be set to the 11th floor, the 21st floor, and the 31st floor.
[0080]
Further, since the cross section of the rope runout restraining fixing member 60 is arcuate or smoothly chamfered, the ropes are not damaged when contacting the main rope 12 or the compensation rope 15. Accordingly, the ropes 12 and 15 can have a long life.
[0081]
As described above, according to the present embodiment, the oblique turning arm 40 is connected to the main rope 12 above the ride 13 or the compensation rope 15 (elevator rope) below the ride 13 from the outside of the climbing orbit of the ride 13. ), The elevator rope can be effectively prevented from swinging.
[0082]
In particular, in the case of the present embodiment, the oblique turning arm 40 rotates by passing through a conical surface orbit about an axis of 45 degrees obliquely, so that the elevator rope can be moved more effectively. Since the tilting arm 50 acts as a receiver of the rope that is pulled by the oblique turning arm 40, the elevator rope can be guided more effectively along the ideal track.
[0083]
Further, since the turning drive shaft 41 and the tilt drive shaft 51 can be supported by an intermediate beam or an elevator guide rail, the steady rest device 30 does not become large and maintenance work is easy.
[0084]
Further, by operating the turning arm 50 and the oblique turning arm 40 using various kinds of input information, a rope steadying device can be realized at an effective timing.
[0085]
Next, an elevator rope steadying device according to a second embodiment of the present invention will be described with reference to FIG. FIG. 8 is a schematic configuration diagram of an elevator rope steadying device according to the second embodiment.
[0086]
As shown in FIG. 8, in the elevator rope steadying device 30 according to the present embodiment, the inclined swivel arm 40 can contact the main rope 12 or the compensation rope 15 in a state substantially perpendicular to the lifting or lowering track of the riding rod 13. A plurality of rotating rollers 49 that can rotate in the same direction as the moving direction of the main rope 12 or the compensation rope 15 are arranged at a narrower interval than the diameters of the main rope 12 or the compensation rope 15 in the portion of the inclined arm 40. Has been placed.
[0087]
In addition, the movement direction of the main rope 12 or the compensation rope 15 in the recess 50r of the tilt arm 50 (the portion that can contact the main rope 12 or the compensation rope 12 in a state substantially orthogonal to the lifting or lowering trajectory of the riding rod 13) A plurality of rotation rollers 59 that can rotate in the same direction are arranged at intervals smaller than the diameters of the main rope 12 or the compensation rope 15.
[0088]
Other configurations are substantially the same as those of the elevator rope steadying apparatus according to the first embodiment shown in FIGS. 1 to 5. In the second embodiment, the same parts as those in the first embodiment shown in FIGS. 1 to 5 are denoted by the same reference numerals, and detailed description thereof is omitted.
[0089]
According to the present embodiment, since the frictional force between the oblique turning arm 40 and the turning arm 50 and the main rope 12 or the compensation rope 15 is smaller, the main rope 12 or the compensation rope 15 is more likely to be damaged. Get smaller.
[0090]
Moreover, since each rotation roller 49 and 59 is arrange | positioned at the space | interval narrower than the diameter of the main rope 12 and the compensation rope 15, respectively, each rope does not get pinched between the rotation rollers 49 and 59. .
[0091]
Note that the tilt arm 50 in each of the above embodiments is supported by the tilt drive shaft 51 via a safety clutch mechanism 100 (second clutch mechanism) that is normally connected and can be released only during an abnormality. It is preferable. This will be described with reference to FIGS.
[0092]
In FIG. 9, the safety clutch mechanism 100 is in a connected state, and the tilt arm 50 is in a state substantially parallel to the lifting or lowering track of the riding rod 13.
[0093]
10 and 11, the safety clutch mechanism 100 is in a connected state, and the tilting arm 50 is in a state substantially orthogonal to the lifting or lowering track of the riding rod 13 by the rotation of the tilting drive shaft 51. In FIG. 10, the oblique turning arm 40 is in a state substantially parallel to the raising / lowering trajectory of the riding rod 13, and in FIG. 11, the oblique turning arm 40 is in a state substantially orthogonal to the raising / lowering trajectory of the riding rod 13.
[0094]
In FIG. 12, the safety clutch mechanism 100 is in the released state, and the tilting arm 50 should be in a state substantially orthogonal to the lifting or lowering trajectory of the riding rod 13 by the tilting drive shaft 51. Is in a state substantially parallel to the up-and-down trajectory of the riding rod 13.
[0095]
Details of the safety clutch mechanism 100 will be described with reference to FIGS. 9 to 12, particularly FIG. 11.
[0096]
The safety clutch mechanism 100 has a central ring portion 101 that can rotate coaxially with the tilt drive shaft 51. The central ring portion 101 is connected to the upper ring portion 102 by a wire 112. The upper ring portion 102 is supported so as to be rotatable on the lifting or lowering track of the riding rod 13. From the upper ring portion 102, a contact needle portion 102 n that extends through the center of rotation and extends toward the lifting track of the riding rod 13 extends.
[0097]
The connection relationship between the ring portions 101 and 102 and the wire 112 is, for example, as shown in FIG. Thereby, the rotation of the upper ring portion 102 and the rotation of the central ring portion 101 are interlocked in both directions.
[0098]
On the other hand, the central ring portion 101 is connected to the lower ring portion 103 by a wire 113. The lower ring portion 103 is supported so as to be rotatable on the lifting or lowering track of the riding rod 13. Also from the lower ring portion 103, a contact needle portion 103n that extends through the center of rotation and extends toward the elevating orbit of the riding rod 13 extends.
[0099]
The connection relationship between the ring portions 101 and 103 and the wire 113 is also as shown in FIG. 13, for example. As a result, the rotation of the lower ring portion 103 and the rotation of the central ring portion 101 are interlocked in both directions.
[0100]
With the configuration as described above, when the riding rod 13 comes into contact with the contact needle portion 102n and pushes it down, all the ring portions 101 to 103 rotate in the A direction (see FIG. 11). Moreover, when the riding rod 13 contacts and pushes up the contact needle part 103n, all the ring parts 101-103 rotate in the B direction (refer FIG. 11).
[0101]
Now, from the center ring part 101, the protrusion part 101p for a link is extended. One end of the connection link 105 is link-connected (rotatably connected) to the end of the link protrusion 101p. The other end of the connection link 105 is linked to one end of the locking link 106 (rotatable connection). In this case, the other end of the connection link 105 is also slidable with respect to one end of the engagement link 106 in order to return to the locked state (such a link connection is, for example, a cylindrical shaft element and Long hole elements).
[0102]
The locking link 106 is rotatably fixed to a support member 108 that is integral with the tilting drive shaft 51 at a fulcrum portion 106p near one end connected to the other end of the connection link 105. Then, on the side opposite to the one end with the fulcrum part 106p interposed therebetween, the locking piece 120 is fixed in parallel to the tilting arm 50 and extends from the tilting drive shaft 51 to the rear of the arm 50. A recess 106r for engagement is provided.
[0103]
In the connected state of the safety clutch mechanism 100 in FIGS. 9 to 11, the locking piece 120 and the recess 106r are in the engaged state. In order to make this state a stable state, the balance urging devices 131 and 132 apply urging forces that oppose each other to the connecting portion between the end of the link protrusion 101p and one end of the connection link 105. Further, a return spring 133 is provided on the side farther from the fulcrum part 106p than the recess 106r, with the connection state position of the locking link 106 as a basic state.
[0104]
The safety clutch mechanism 100 as described above operates as follows.
[0105]
As shown in FIGS. 9 to 11, when the contact needle portions 102n and 103n and the riding rod 13 do not contact and receive no external force, the engagement state between the locking piece 120 and the recess 106r is maintained, and the safety clutch mechanism 100 is rotationally driven around the tilt drive shaft 51 integrally with the tilt arm 50. At this time, the contact needle parts 102n and 103n are in a parallel state or in a state perpendicular to the ascending / descending track of the riding rod 13 corresponding to the state of the tilt arm 50.
[0106]
In the state shown in FIG. 11, when the contact needle portion 102 n comes into contact with the riding rod 13 and receives a downward external force, all the ring portions 101 to 103 are forcibly rotated in the A direction. In particular, due to the rotation of the central ring portion 101, the balance of the force at the connection portion between the end of the link projection 101p and one end of the connection link 105 is lost, and the connection portion also rotates around the rotation drive shaft 51 in the A direction. To do. Along with this, the other end of the connection link 105 strongly pulls one end of the locking link 106 toward the tilt drive shaft 51.
[0107]
As a result, the concave portion 106r of the locking link 106 rotates in the A direction around the fulcrum portion 106p against the spring force of the return spring 133, and finally the locking piece 120 comes out of the concave portion 106r. Thereafter, due to the action of gravity, the locking piece 120 and the tilting arm 50 are in a state substantially parallel to the ascending / descending track of the riding rod 13 (safe clutch release state: see FIG. 12).
[0108]
At this time, due to the action of the link bar 43b, the clutch mechanism 43a of the oblique turning arm 40 is operated, and the oblique turning arm 40 is also in a state substantially parallel to the ascending / descending track of the riding rod 13.
[0109]
As described above, it is possible to reliably prevent the riding rod 13 moving downward from coming into contact with the oblique turning arm 40 and the tilting arm 50.
[0110]
On the other hand, in the state shown in FIG. 11, when the contact needle portion 103 n comes into contact with the riding rod 13 and receives an upward external force, all the ring portions 101 to 103 are forcibly rotated in the B direction. In particular, due to the rotation of the central ring portion 101, the balance of the force at the connecting portion between the end of the link protrusion 101 p and the one end of the connecting link 105 is lost, and the connecting portion also rotates in the B direction around the rotation drive shaft 51. To do. Along with this, the other end of the connection link 105 strongly pulls one end of the locking link 106 toward the tilt drive shaft 51.
[0111]
As a result, the concave portion 106r of the locking link 106 rotates in the A direction around the fulcrum portion 106p against the spring force of the return spring 133, and finally the locking piece 120 comes out of the concave portion 106r. Thereafter, due to the action of gravity, the locking piece 120 and the tilting arm 50 are in a state substantially parallel to the ascending / descending track of the riding rod 13 (safe clutch release state: see FIG. 12).
[0112]
At this time, due to the action of the link bar 43b, the clutch mechanism 43a of the oblique turning arm 40 is operated, and the oblique turning arm 40 is also in a state substantially parallel to the ascending / descending track of the riding rod 13.
[0113]
As described above, it is possible to reliably prevent the riding rod 13 moving upward from coming into contact with the oblique turning arm 40 and the tilting arm 50.
[0114]
12 is returned from the safety clutch released state to the safety clutch engaged state, the driving means 53 causes the support member 108 (integrated with the tilt drive shaft 51) of the safety clutch mechanism 100 to be parallel to the tilt arm 50. Thus, it can be automatically performed by the action of the return spring 133 and the fact that the other end of the connection link 105 can slide relative to one end of the locking link 106.
[0115]
But as a safe clutch mechanism, it is not limited to said form, You may employ | adopt another clutch mechanism.
[0116]
Next, some examples of use of the above embodiments will be described with reference to flowcharts.
[0117]
FIG. 14 shows an example of operation when the elevator rope steadying device 30 is operated based on the measured value of the wind speed.
[0118]
In this case, as shown in FIG. 14, in a control unit (not shown), for example, it is determined whether or not the wind speed is 20 m / second or more (STEP 11). If the wind speed is not 20 m / sec or more, the parking switch (stop switch for the riding rod 13) is manually set to the “R” mode, for example, as a normal state (STEP 12). In this case, the elevator rope steadying device 30 maintains the stored state of the arms 40 and 50 (STEP 13).
[0119]
On the other hand, if the wind speed is 20 m / second or more, the parking switch (stop switch of the riding rod 13) is manually set to the “P” mode, for example, as an abnormal state (STEP 14). In that case, the riding board 13 is moved to a predetermined retreat floor, for example, the 40th floor (STEP 15). Then, it is determined whether or not the carriage 13 has arrived on the 40th floor (STEP 16), and then the elevator rope steadying device 30 is operated, that is, the rope arm 50 and the slant turning arm 40 are used to operate the rope. Carry out hand-drawing.
[0120]
Based on the above, the elevator rope steadying device 30 can be effectively operated based on the measured value of the wind speed.
[0121]
FIG. 15 is an example of operation when the operation of the ride 13 is stopped during an earthquake control operation, a self-control operation, or due to a failure or the like.
[0122]
In this case, as shown in FIG. 15, the control unit (not shown) determines whether or not there is an operation stop command (STEP 21). If there is no operation stop command, as a normal state, the elevator rope steadying device 30 maintains the storage state of the arms 40 and 50 (STEP 22).
[0123]
On the other hand, if there is an operation stop command, the stop position of the riding rod 13 (usually stopped at the retreat floor) is detected as an abnormal state. The position of the riding rod 13 is preferably confirmed by two types of devices: a pulse generator installed in the governor and a sensor installed in the hoistway. Then, it is determined whether or not the detected position of the riding rod 13 interferes with the operating range of the rope steady rest device 30 (STEP 23).
[0124]
The slant turning arm 40 and the tilt arm 50 of the rope steady rest device 30 are often installed under the first floor of the retreat floor. Therefore, it is considered that there are many cases where the operating range of any of the rope steady stop devices 30 interferes with the stop position of the riding rod 13.
[0125]
And about the rope steadying apparatus 30 which the operation range interferes with the stop position of the riding rod 13, the accommodation state of the arms 40 and 50 is maintained, and only the other rope steadying apparatus 30 is operated. Then, the rope is hand-drawn by using the tilt arm 50 and the oblique turning arm 40 of the other rope steadying device 30 (STEP 24).
[0126]
If there is no rope steadying device 30 whose operating range interferes with the stopping position of the riding rod 13, the ropes are pulled by using the tilting arm 50 and the slant turning arm 40 of all the rope steadying devices 30. Implement (STEP 25).
[0127]
According to the above, contact (interference) between the riding rod 13 and the rope steady rest device 30 is effectively avoided.
[0128]
FIG. 16 is an example of operation when driving (resuming) the riding rod 13 is started.
[0129]
In this case, as shown in FIG. 16, it is determined whether or not the tilting arm 50 is in the retracted state (substantially parallel to the lifting or lowering track of the riding rod 13) using an appropriate sensor or the like (STEP 31). . If it is not in the stowed state, it is considered that the rope steady rest device 30 is in an operating state (rope pulling state). Therefore, the rope steady rest device 30 is returned (STEP 33) after waiting for resumption of operation (STEP 32).
[0130]
When the tilt arm 50 is in the retracted state, it is determined by using an appropriate sensor or the like whether or not the oblique turning arm 40 is in the retracted state (substantially parallel to the climbing orbit of the riding rod 13). (STEP 34). If it is not in the stowed state, it is considered that the rope steady rest device 30 is in an operating state (rope pulling state). Therefore, the rope steady rest device 30 is returned (STEP 33) after waiting for resumption of operation (STEP 32).
[0131]
When the oblique turning arm 40 is also in the retracted state, it is determined whether or not each of the clutch mechanisms 43a, 53a, and 100 is in the connected state using an appropriate sensor or the like (STEP 35). If it is not in the connected state, it waits for resumption of operation (STEP 32), returns the rope steady rest device 30 and returns each clutch to the connected state (STEP 33).
[0132]
When each clutch mechanism 43a, 53a, 100, etc. is in a connected state, the operation of the elevator is started (STEP 36).
[0133]
As shown in FIG. 17, the limit switch A for detecting the connection / release state of the clutch mechanism of the oblique turning arm 40 is first discriminated (STEP 41), and then the clutch mechanism of the tilt arm 50 is connected / released. It is also effective to discriminate the limit switch B for detecting (STEP 42) and not to judge that the arm is in the retracted state (STEP 43, STEP 44) when any of these clutch mechanisms is disengaged. is there.
[0134]
【The invention's effect】
As described above, according to the present invention, the swivel arm rotates from the outside of the lifting or lowering track of the ride toward the ideal track of the main rope above the ride or the compensation rope (elevator rope) below the ride. By doing so, the elevator rope can be pulled up effectively, and the elevator rope can be effectively prevented from swinging.
[0135]
Moreover, since the turning drive shaft can be supported by an intermediate beam or an elevator guide rail, the apparatus does not become large and maintenance work is easy.
