The circulation of fast device rope 19 stops.When the circulation of overspeed governor 19 stops, actuating strut 16 is operated, emergency braking device 15
It is acted, 9 emergent stopping of carriage.
Fig. 2 is the main view for showing the relationship between the car guide rail 11 of Fig. 1 and emergency braking device 15, Fig. 3 be along
The cross-sectional view of III-III line in Fig. 2, Fig. 4 are the main views for showing the state when emergency braking device 15 in Fig. 1 acts,
Fig. 5 is the cross-sectional view along the V-V line in Fig. 4.
Emergency braking device 15 has the grasping part for the pair of right and left for grasping corresponding car guide rail 11.As shown in Fig. 2, each
A grasping part has a pair of of chock 25, a pair of of chock guiding device 26 and multiple chock guiding device springs 27.
Chock 25 can be along being set to framework of the inclined surface relative to emergency braking device 15 of chock guiding device 26 or more
It is mobile.Chock guiding device spring 27 is set between the framework and chock guiding device 26 of emergency braking device 15.
When usual, chock 25 is opposed with car guide rail 11 across gap as shown in Figure 2.In contrast, in emergent stopping
When device 15 acts, chock 25 is raised.At this point, chock 25 along chock guiding device 26 close to car guide rail 11, it is final such as Fig. 4
It is shown to be contacted with car guide rail 11.
Also, when chock 25 is further lifted, chock 25 pushes chock guiding device 26 in the horizontal direction and moves upwards
It is dynamic, so that chock guiding device spring 27 compresses.By the compression of the chock guiding device spring 27, from chock 25 to car guide rail 11
The pressing force of effect increases, corresponding with the biting amount of chock 25 in the frictional force that car guide rail 11 and emergency braking device 15 generate
Ground increases.Chock 25 grasps car guide rail 11,9 emergent stopping of carriage as a result,.
Fig. 6 is the explanatory diagram for showing the movement of the emergency braking device 15 when the suspension body 8 in Fig. 1 is broken.Promptly stopping
The actuating strut 16 (omitting in Fig. 1) for acting emergency braking device 15 is equipped on locking apparatus 15 in a rotatable way.Movement
The front end of bar 16 is connect with chock 25.When actuating strut 16 is raised (into Fig. 6 when rotating counterclockwise), chock 25
It is synchronously raised with actuating strut 16.That is, by making the rotating counterclockwise into Fig. 6 of actuating strut 16, emergency braking device
15 movements.
It is equipped with torsional spring 22 in emergency braking device 15, which adds direction and make promptly to actuating strut 16
The direction that arresting stop 15 is acted is the power of opposite direction (clockwise direction in Fig. 6).Torsional spring 22 is applied just
Beginning rotation amount.Due to the initial rotation amount, generate for preventing actuating strut 16 from surprisingly revolving for the resistance for lifting actuating strut 16
Turn.Therefore, even traction machine brake 7 is acted and produces up-down vibration in carriage 9 in the traveling of carriage 9
When, actuating strut 16 will not be raised, and emergency braking device 15 not will do it movement.
Interconnecting piece 23 is fixed on overspeed governor 19.Lifting rod 24 be connected to interconnecting piece 23 and actuating strut 16 it
Between.That is, overspeed governor 19 is connect by interconnecting piece 23, lifting rod 24 and actuating strut 16 with emergency braking device 15.Also, it mentions
The upper end for playing stick 24 is connect with interconnecting piece 23 in a rotatable manner.Moreover, the lower end of lifting rod 24 is to rotate freely
Mode connect with actuating strut 16.
The limiter of speed mechanism 100 of embodiment 1 has governor sheave 18, overspeed governor 19 and tensioning wheel 20.Outstanding
When hanging body 8 is broken, carriage 9 is fallen downwards with the acceleration of gravity of 1G.At this point, limiter of speed mechanism 100 is not influenced by gravity, because
And with the aG speedup (a < 1.0) lower than 1G.Therefore, it is poor that acceleration is generated between carriage 9 and limiter of speed mechanism 100.It limits as a result,
The speed of Su Qi mechanism 100 becomes the kV (k < 1) lower than car speed V, and actuating strut 16 is raised, thus emergency braking device 15
It is acted.In addition, car speed V when emergency braking device 15 is acted is lower than normal speed Vo.
Fig. 7 is the emergency braking device 15 shown when stopping carriage 9 rapidly by the traction machine brake 7 in Fig. 1
The explanatory diagram of malfunction.When traction machine brake 7 is acted in the rising of carriage 9, carriage 9 is with about 0.3G deceleration.At this point,
Downward acceleration is generated in carriage 9.On the other hand, limiter of speed mechanism 100 does not bear braking deceleration power directly, than 0.3G
Low acceleration bG slows down (b < 0.3).Therefore, the speed kV of limiter of speed mechanism 100 is higher than the speed V (k > 1) of carriage 9, dynamic
Make emergency braking device 15 when bar 16 rises to be malfunctioned.
Here, Fig. 8 is the curve for showing the relationship between the position of the actuating strut 16 in Fig. 7 and the lifting force of actuating strut 16
Figure.When carrying out emergency braking action, the big F1 of power that the elasticity rate of torsional spring 22 lifts actuating strut 16, actuating strut 16 cannot
Lift.On the other hand, when suspension body 8 is broken, it is F2 bigger than the elastic force of torsional spring 22 to lift power, and emergency braking device 15 carries out
Movement.
At this point, when the difference (F1+F2) of the lifting force in emergency braking action and when suspension body 8 is broken is smaller, for preventing
The elastic force setting range of the torsional spring 22 only malfunctioned is restricted.Therefore, because the difficulty of setting, generates emergent stopping dress
15 malfunction is set, or generates the increase of car speed because of the delay of the actuation time of emergency braking device 15.
In order to solve this problem, in the embodiment 1 using the rotator inertia quality of limiter of speed mechanism 100 according to traveling side
To and change mechanism.That is, carriage 9 decline when, additional mass is integrally formed with tensioning wheel 20 and is rotated, thus with limiter of speed
The rotator inertia quality for the part that mechanism 100 integrally moves increases.On the other hand, carriage 9 rise when, make additional mass from
Tensioning wheel 20 is detached from, and additional mass does not contribute the inertia of limiter of speed mechanism 100.
Fig. 9 is the explanatory diagram for illustrating the movement of the limiter of speed mechanism 100 of embodiment 1 when carriage rises, and Figure 10 is to say
The explanatory diagram of movement of the limiter of speed mechanism 100 of bright embodiment 1 in cage descending, Figure 11 are the tensionings for being shown specifically Fig. 9
The main view of wheel 20.Rotating circular disk 28 is provided in rotary shaft identical with tensioning wheel 20.Tensioning wheel 20 and rotating circular disk 28
It is connected by rotary shaft 29.
Rotary shaft 29 is directly connected to rotating circular disk 28.Also, rotary shaft 29 passes through ratchet mechanism 30 as shown in figure 11
It is connect with tensioning wheel 20.Ratchet mechanism 30 has ratchet 31, multiple pawls 32 and multiple springs 33.Ratchet 31 is fixed on rotary shaft
29, it is rotated integrally with rotary shaft 29.Multiple tooth 31a are equipped in the periphery of ratchet 31.
Each pawl 32 is supported in tensioning wheel 20 in a rotatable way.Spring 33 is set between tensioning wheel 20 and pawl 32,
On the periphery that pawl 32 is pressed against to ratchet 31.
When carriage rises, in tensioning wheel 20 along Figure 11 when being rotated clockwise, pawl 32 is on the periphery of ratchet 31
It slides and is integrally formed and rotates with tensioning wheel 20.Therefore, ratchet 31 does not rotate, and rotary shaft 29 does not also rotate.
On the other hand, in cage descending, when tensioning wheel 20 is along Figure 11 when rotating counterclockwise, pawl 32 bites tooth
In 31a, thus ratchet 31 rotates together with tensioning wheel 20.Rotary shaft 29 and rotating circular disk 28 and tensioning wheel 20 become one as a result,
Body and rotate.In this way, the rotation of the tensioning wheel 20 when ratchet mechanism 30 does not rise carriage 9 passes to rotating circular disk 28, and incite somebody to action
The rotation of tensioning wheel 20 when carriage 9 declines passes to rotating circular disk 28.
The inertia mass additional mechanism providing additional operation 101 of embodiment 1 has rotating circular disk 28, rotary shaft 29 and ratchet mechanism 30,
Additional inertia mass is added when carriage 9 declines to limiter of speed mechanism 100, the additional of inertia mass is released when carriage 9 rises.
In this way, tensioning wheel 20 and rotating circular disk 28 are integrally formed and rotate in the case where carriage 9 declines, thus and sedan-chair
Compartment is compared when rising, and the rotator inertia quality of limiter of speed mechanism 100 increases.Therefore, in cage descending, limiter of speed mechanism 100
Movement postpone a little relative to the movement of carriage 9, and when carriage rises, limiter of speed mechanism 100 is easily without lingeringly
Follow the movement of carriage 9.
Therefore, when in cage descending, suspension body 8 is broken, the acceleration difference between limiter of speed mechanism 100 and carriage 9 increases
Greatly, emergency braking device 15 can be acted immediately, in contrast, when in the emergency braking action when carriage rises (or
Person due to passenger mischief and when carriage being caused to teetertotter), acceleration subtractive between limiter of speed mechanism 100 and carriage 9
It is small, it is reliably prevented from emergency braking device 15 and is malfunctioned.In such manner, it is possible to prevent emergent stopping using simple structure
The malfunction of device 15 realizes that the space of hoistway 1 is saved.
In addition, can substantially expand the setting model of the torsional spring 22 for preventing the malfunction of emergency braking device 15
It encloses, is easy to carry out so that adjusting operation, and can be more reliably prevented from and be trapped in the lift car passenger due to malfunction.
In addition, rotary shaft 29 and rotating circular disk 28 are connect with tensioning wheel 20 by ratchet mechanism 30, it is thus possible to utilize
Simple structure substantially changes the rotator inertia quality of the limiter of speed mechanism 100 when carriage 9 rises and when decline.
In addition, being difficult to sufficiently increase rotator inertia only relying on rotating circular disk 28 due to the size constrained of rotating circular disk 28
In the case where quality, as shown in FIG. 12 and 13, by the rotation except the additional rotating circular disk 28 of inertia mass additional mechanism providing additional operation 101
Turn the i.e. additional disk 34 of disk and the cricoid rope 35 as carrier, can be easy to increase the rotation of limiter of speed mechanism 100
Inertia.Rope 35 is winded on rotating circular disk 28 and additional disk 34, and the rotation of rotating circular disk 28 is passed to additional disk 34.
In addition, in the embodiment 1, rotating circular disk 28 is connect with tensioning wheel 20 by ratchet mechanism 30, but can also be with
It is connect with governor sheave 18.
Embodiment 2
In the following, Figure 14 is the structure chart for showing the major part of lift appliance of embodiments of the present invention 2.In embodiment party
In formula 2, replace rotating circular disk 28, rotary shaft 29 and the ratchet mechanism 30 of embodiment 1, as the attached of inertia mass additional mechanism providing additional operation
The lower part velocity variations section (lower area of hoistway 1) for adding mass body 41 to be arranged in hoistway 1 is i.e. from lowest level up to reaching
In region until normal speed.Also, the 1st contact is equipped in connecting moves bar 16 and the interconnecting piece of limiter of speed mechanism 100 23
Component 38.
Additional mass body 41 includes lower part rotating circular disk 21, adjacent with tensioning wheel 20；Upper rotating disk 36, matches
It sets in the surface of lower part rotating circular disk 21；As the cricoid rope 37 of carrier, it is winded at these rotating circular disks 21,36
On；2nd contact component 39, in lower part, rope 37 is fixed in the side of rotating circular disk 21；And counterweight 40 is resetted, in lower part
Rope 37 is fixed in the other side of rotating circular disk 21.
1st contact component 38 is contacted when carriage 9 drops to lower part velocity variations section with the 2nd contact component 39.Counterweight
40 quality is configured to the value slightly heavier than the 2nd contact component 39.Other structures are identical as embodiment 1.
As shown in figure 14, when carriage 9 is located near top layer, the 1st contact component 38 leaves the 2nd contact component 39.This
Sample, in the state that the 1st contact component 38 leaves the 2nd contact component 39, due to the matter of the 2nd contact component 39 and reset counterweight 40
It is poor to measure, and counterweight 40 is close to the 21, the 2nd contact component 39 of lower part rotating circular disk close to upper rotating disk 36.
As shown in figure 15, when carriage 9 declines and reaches lower part velocity variations section, the 1st contact component 38 is contacted with the 2nd
Component 39 contacts, and limiter of speed mechanism 100 and additional mass body 41 are integrally formed and are moved.As a result, when carriage 9 is in lower part speed
When constant interval declines, additional rotator inertia quality is added to limiter of speed mechanism 100.
In addition, as shown in figure 16, when carriage 9 rises from lower part velocity variations section, the 1st contact component 38 leaves the 2nd
Contact component 39.At this point, the 2nd contact component 39 is in the state that the 2nd contact component 39 leaves the 1st contact component 38 to reset
The determined acceleration of poor quality of counterweight 40 and the 2nd contact component 39 rises.
Therefore, if setting the quality of counterweight 40 in a manner of reducing the climb acceleration of the 2nd contact component 39, the
2 contact components 39 are risen with the speed slow enough of the rate of climb compared to carriage 9.As a result, as shown in figure 16, the 1st contact component
38 risings while being left from the 2nd contact component 39.Therefore, when carriage 9 rises, additional mass body 41 is from limiter of speed mechanism
100 are detached from, and are released from by the additional of inertia mass that additional mass body 41 is realized.
In such lift appliance, the rotator inertia quality of the part integrally moved with limiter of speed mechanism 100,

Cylinder 44 protrudes maximum, and the 2nd contact component 47 is located at the top of cylinder 44.
As shown in figure 18, when carriage 9 declines and reaches lower part velocity variations section, the 1st contact component 38 is contacted with the 2nd
Component 47 contacts, and limiter of speed mechanism 100 and plunger 43 are integrally formed and are moved.At this point, limiter of speed mechanism 100 passes through plunger 43
Lower end throttle orifice, from cylinder 44 oil 46 bear fluid resistance (damping force).That is, when carriage 9 is in lower part velocity variations
When section declines, plunger 43 declines while applying resistance to limiter of speed mechanism 100.
Although the inertia force of limiter of speed mechanism 100 is constant as a result, the damping force generated in limiter of speed mechanism 100
Increase, thus in the case that when lower part velocity variations section declines, suspension body 8 is broken carriage 9, carriage 9 and limiter of speed mechanism
It is poor that biggish acceleration is generated between 100, thus emergency braking device 15 is acted immediately, low speed and can safely be prevented
Carriage 9 is fallen.

But the rate of climb of the fluid resistance of the oil 46 due to plunger 43, plunger 43 and the 2nd contact component 47 is than connection
The rate of climb in portion 23 is slow.As a result, as shown in figure 19,38 rising while leaving the 2nd contact component 47 of the 1st contact component.
That is, plunger 43 is detached from when carriage 9 rises from limiter of speed mechanism 100.
Therefore, even accident brake is acted in the rising of carriage 9, between carriage 9 and limiter of speed mechanism 100
Acceleration difference it is also small, it is thus possible to prevent emergency braking device 15 from being malfunctioned.In such manner, it is possible to anti-using simple structure
The only malfunction of emergency braking device 15 realizes that the space of hoistway 1 is saved.
In addition, increasing the decaying generated in limiter of speed mechanism 100 when only declining in the velocity variations section of lower part in carriage 9
Power, it is thus possible to substantially reduce the region that emergency braking device 15 is malfunctioned.
In addition, the rate of climb of plunger 43 can be according to the throttle hole area of the lower end of plunger 43, the bullet of reset spring 45
Power and the viscosity of oil 46 are adjusted.
In addition, the 1st contact component 38 is configured to and additional mass body 41 or damping mechanism 42 in embodiment 2,3
It directly contacts, but the magnet to repel each other can also be set in contact surface.Thereby, it is possible to eliminate the impact generated with contact
Sound makes passenger in carriage not generate discomfort.

In the following, Figure 20 is the structure chart for showing the major part of lift appliance of embodiments of the present invention 4.In embodiment party
In formula 4, replace the additional mass body 41 of embodiment 2, the lower part velocity variations section in hoistway 1 is arranged in friction extensible guide 49
In.Friction extensible guide 49 and car guide rail 11 erect setting in parallel.
In addition, wedge structures 48 are arranged in interconnecting piece 23, replace the 1st contact portion of embodiment 2 in embodiment 4
Part 38.The resistance additional mechanism providing additional operation of embodiment 4 is the friction mechanism 60 with friction extensible guide 49 and wedge structures 48.In addition, figure

In the following, Figure 23 is the top view for showing the friction mechanism 60 of Figure 20, Figure 24 is along the XXIV-XXIV line in Figure 23
Cross-sectional view.The cross-sectional width of the upper end of friction extensible guide 49 is gradually reduced with towards upper end.Wedge structures 48 have one
To friction chock 50, multiple drag wedge sub-springs 51, a pair of of guide member 52, multiple horizontal direction springs 53 and framework 54.
Friction chock 50 is configured to when carriage 9 is located at lower part velocity variations section from sandwich friction extensible guide 49.
Drag wedge sub-spring 51 is between the lower end and framework 54 of friction chock 50.Friction chock 50 can pass through chock spring 51
It is flexible and move up and down.
The inclined surface guided to corresponding friction chock 50 is equipped in each guide member 52.Horizontal direction spring 53
