Fig. 6 is the explanation figure of the action of the emergency braking device 15 when showing the fracture of suspension body 8 in Fig. 1.Promptly stopping
Rotatably provided with the actuating strut 16 (omitting in Fig. 1) for acting emergency braking device 15 on locking apparatus 15.Action
The front end of bar 16 is connected with chock 25.When actuating strut 16 is raised when counterclockwise rotates () into Fig. 6, chock 25
Synchronously it is raised with actuating strut 16.That is, by making counterclockwise rotates of the actuating strut 16 into Fig. 6, emergency braking device
15 actions.
Torsional spring 22 is provided with emergency braking device 15, the torsional spring 22 is to the additional direction of actuating strut 16 with making promptly
The direction that arresting stop 15 is acted is the power of opposite direction (clockwise direction in Fig. 6).Torsional spring 22 is applied in just
Beginning rotation amount.Due to the initial rotation amount, produce for the resistance for lifting actuating strut 16, prevent the unexpected rotation of actuating strut 16
Turn.Therefore, even traction machine brake 7 is acted and generates up-down vibration in car 9 in the traveling of car 9
When, actuating strut 16 will not be also raised, and emergency braking device 15 will not be acted.
Connecting portion 23 is fixed with overspeed governor 19.Lifting rod 24 be connected to connecting portion 23 and actuating strut 16 it
Between.That is, overspeed governor 19 is connected by connecting portion 23, lifting rod 24 and actuating strut 16 with emergency braking device 15.Also, carry
The upper end for playing rod 24 is connected with connecting portion 23 in a rotatable manner.Moreover, the bottom of lifting rod 24 is to rotate freely
Mode be connected 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, car 9 is fallen downwards with 1G acceleration of gravity.Now, limiter of speed mechanism 100 is not influenceed by gravity, because
And with the aG speedup (a lower than 1G<1.0).Therefore, acceleration is produced between car 9 and limiter of speed mechanism 100 poor.Thus, limit
The speed of Su Qi mechanisms 100 turns into the kV (k lower than car speed V<1), actuating strut 16 is raised, thus emergency braking device 15
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 when showing to make the car 9 rapidly stop by the traction machine brake 7 in Fig. 1
The explanation figure of misoperation.When traction machine brake 7 is acted in the rising of car 9, car 9 is slowed down with about 0.3G.Now,
Downward acceleration is produced in car 9.On the other hand, limiter of speed mechanism 100 does not bear braking deceleration power directly, with than 0.3G
Low acceleration bG decelerations (b<0.3).Therefore, the speed kV of limiter of speed mechanism 100 is higher than the speed V (k of car 9>1), dynamic
Make emergency braking device 15 when bar 16 rises and carry out misoperation.
Here, Fig. 8 is the curve for showing the relation 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 can not
Lift.On the other hand, when suspension body 8 is broken, elastic force big F2 of the power than torsional spring 22 is lifted, emergency braking device 15 is carried out
Action.
Now, when the difference (F1+F2) of the lifting force in emergency braking action and when suspension body 8 is broken is smaller, for preventing
Only the elastic force setting range of the torsional spring 22 of misoperation is restricted.Therefore, because the difficulty of setting, produces emergent stopping dress
15 misoperation is put, or produces because of the delay of the actuation time of emergency braking device 15 increase of car speed.
In order to solve the problem, using the rotator inertia quality of limiter of speed mechanism 100 according to traveling side in embodiment 1
To and change mechanism.That is, when car 9 declines, additional mass is integrally formed and rotated with tensioning wheel 20, thus with limiter of speed
The rotator inertia quality increase for the part that mechanism 100 is integratedly moved.On the other hand, when car 9 rises, make additional mass from
Tensioning wheel 20 departs from, and additional mass is not contributed the inertia of limiter of speed mechanism 100.
Fig. 9 is the explanation figure for the action for illustrating the limiter of speed mechanism 100 of embodiment 1 when car rises, and Figure 10 is to say
The explanation figure of action of the limiter of speed mechanism 100 of bright embodiment 1 in cage descending, Figure 11 is the tensioning for being shown specifically Fig. 9
The front view of wheel 20.With being provided with rotating circular disk 28 in the identical rotary shaft of 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 connected 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, rotated integrally with rotary shaft 29.Multiple tooth 31a are provided with the periphery of ratchet 31.
Each pawl 32 is rotatably supported in tensioning wheel 20.Spring 33 is located between tensioning wheel 20 and pawl 32,
On the periphery that pawl 32 is pressed against to ratchet 31.
When car rises, in tensioning wheel 20 along Figure 11 when being rotated clockwise, pawl 32 is on the periphery of ratchet 31
Slide and be integrally formed and rotate 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 counterclockwise rotates of the tensioning wheel 20 along Figure 11, pawl 32 bites tooth
In 31a, thus ratchet 31 rotates together with tensioning wheel 20.Thus, rotary shaft 29 and rotating circular disk 28 turn into one with tensioning wheel 20
Body and rotate.So, the rotation of the tensioning wheel 20 when ratchet mechanism 30 does not rise car 9 passes to rotating circular disk 28, and incites somebody to action
The rotation of tensioning wheel 20 when car 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,
To the inertia mass of the additional addition of limiter of speed mechanism 100 when car 9 declines, the additional of inertia mass is released when car 9 rises.
So, in the case where car 9 declines, tensioning wheel 20 and rotating circular disk 28 are integrally formed and rotated, thus and sedan-chair
Railway carriage or compartment is compared when rising, the rotator inertia quality increase of limiter of speed mechanism 100.Therefore, in cage descending, limiter of speed mechanism 100
Motion of the motion relative to car 9 postpone a little, and when car rises, limiter of speed mechanism 100 is easily without lingeringly
Follow the motion of car 9.
Therefore, when suspension body 8 is broken when in cage descending, the acceleration difference between limiter of speed mechanism 100 and car 9 increases
Greatly, emergency braking device 15 can be acted immediately, on the other hand, when in the emergency braking action when car rises (or
When person causes the car to teetertotter due to the mischief of passenger), the acceleration subtractive between limiter of speed mechanism 100 and car 9
It is small, it can reliably prevent emergency braking device 15 from carrying out misoperation.In such manner, it is possible to prevent emergent stopping using simple structure
The misoperation of device 15, realizes that the space of hoistway 1 is saved.
In addition, can significantly expand the setting model of the torsional spring 22 of the misoperation for preventing emergency braking device 15
Enclose so that regulation operation is easily carried out, and can be more reliably prevented from being trapped in the lift car passenger because of misoperation.
In addition, rotary shaft 29 and rotating circular disk 28 are connected with tensioning wheel 20 by ratchet mechanism 30, it is thus possible to utilize
The rotator inertia quality of limiter of speed mechanism 100 when simple structure is significantly changed when car 9 rises and declined.
Further, since the size constrained of rotating circular disk 28, is difficult to fully increase rotator inertia only relying on rotating circular disk 28
In the case of quality, as shown in FIG. 12 and 13, by adding the rotation outside rotating circular disk 28 to inertia mass additional mechanism providing additional operation 101
Turn the i.e. additional disk 34 of disk and the rope 35 of the ring-type as carrier, can easily 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 into additional disk 34.
In addition, in embodiment 1, rotating circular disk 28 is connected with tensioning wheel 20 by ratchet mechanism 30, but it is also possible to
It is connected with governor sheave 18.
Embodiment 2
Below, Figure 14 is the structure chart of the major part for the lift appliance for showing 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, be used as the attached of inertia mass additional mechanism providing additional operation
Plus mass body 41 is arranged on bottom velocity variations interval (lower area of hoistway 1) in hoistway 1 i.e. from orlop up to reaching
In region untill normal speed.Also, in connecting moves bar 16 and the connecting portion of limiter of speed mechanism 100 23 provided with the 1st contact
Part 38.
Additional mass body 41 has：Bottom rotating circular disk 21, it is adjacent with tensioning wheel 20；Upper rotating disk 36, it is matched somebody with somebody
Put in the surface of bottom rotating circular disk 21；As the rope 37 of the ring-type of carrier, it is winded at these rotating circular disks 21,36
On；2nd contact component 39, it is fixed on rope 37 in the side of bottom rotating circular disk 21；And counterweight 40 is resetted, it is in bottom
The opposite side of rotating circular disk 21 is fixed on rope 37.
1st contact component 38 is contacted when car 9 drops to bottom velocity variations interval with the 2nd contact component 39.Counterweight
40 quality is configured to than the 2nd contact component 39 slightly heavy value.Other structures are identical with embodiment 1.
As shown in figure 14, when car 9 is located near the superiors, the 1st contact component 38 leaves the 2nd contact component 39.This
Sample, in the state of the 1st contact component 38 leaves the 2nd contact component 39, the matter due to the 2nd contact component 39 with resetting counterweight 40
Amount is poor, and counterweight 40 is close to the contact component 39 of bottom rotating circular disk the 21, the 2nd close to upper rotating disk 36.
As shown in figure 15, when car 9 declines and reaches bottom velocity variations interval, the 1st contact component 38 is contacted with the 2nd
Part 39 is contacted, and limiter of speed mechanism 100 and additional mass body 41 are integrally formed and moved.Thus, when car 9 is in bottom speed
When constant interval declines, to the rotator inertia quality of the additional addition of limiter of speed mechanism 100.
In addition, as shown in figure 16, when car 9 rises from bottom velocity variations interval, the 1st contact component 38 leaves the 2nd
Contact component 39.Now, in the state of the 2nd contact component 39 leaves the 1st contact component 38, the 2nd contact component 39 is with reset
The determined acceleration of poor quality of the contact component 39 of counterweight 40 and the 2nd rises.
Therefore, if setting the quality of counterweight 40 in the way of reducing the climb acceleration of the 2nd contact component 39, the
2 contact components 39 are risen with the slow speed enough of the rate of climb compared to car 9.Thus, as shown in figure 16, the 1st contact component
38 rise while being left from the 2nd contact component 39.Therefore, when car 9 rises, additional mass body 41 is from limiter of speed mechanism
100 depart from, and the additional of inertia mass realized by additional mass body 41 is released from.
In such lift appliance, the rotator inertia quality for the part integratedly moved with limiter of speed mechanism 100,

Sample, in the state of the 1st contact component 38 leaves the 2nd contact component 47, by the restoring force of back-moving spring 45, plunger 43 is from gas
Cylinder 44 protrudes maximum, and the 2nd contact component 47 is located at the top of cylinder 44.
As shown in figure 18, when car 9 declines and reaches bottom velocity variations interval, the 1st contact component 38 is contacted with the 2nd
Part 47 is contacted, and limiter of speed mechanism 100 and plunger 43 are integrally formed and moved.Now, limiter of speed mechanism 100 passes through plunger 43
Lower end throttle orifice, bear fluid resistance (damping force) from the oil 46 in cylinder 44.That is, when car 9 is in bottom velocity variations
When interval declines, plunger 43 declines while resistance is applied to limiter of speed mechanism 100.
Thus, although the inertia force of limiter of speed mechanism 100 is constant, but the damping force produced in limiter of speed mechanism 100
Increase, thus when car 9 is in the decline of bottom velocity variations interval in the case of the fracture of suspension body 8, car 9 and limiter of speed mechanism
Larger acceleration is produced between 100 poor, thus emergency braking device 15 is acted immediately, low speed and can safely prevented
Car 9 is fallen.
In addition, as shown in figure 19, when car 9 rises from bottom velocity variations interval, the 1st contact component 38 leaves the 2nd
Contact component 47.Now, in the state of the 2nd contact component 47 leaves the 1st contact component 38, by the reply of back-moving spring 45
Power, the contact component 47 of plunger 43 and the 2nd rises.
But, due to the fluid resistance of the oil 46 of plunger 43, the rate of climb of plunger 43 and the 2nd contact component 47 is than connection
The rate of climb in portion 23 is slow.Thus, as shown in figure 19, the 1st contact component 38 rises while the 2nd contact component 47 are left.
That is, plunger 43 departs from when car 9 rises from limiter of speed mechanism 100.
Therefore, even accident brake is acted in the rising of car 9, between car 9 and limiter of speed mechanism 100
Acceleration difference it is also small, it is thus possible to prevent emergency braking device 15 carry out misoperation.In such manner, it is possible to anti-using simple structure
The only misoperation of emergency braking device 15, realizes that the space of hoistway 1 is saved.
In addition, the decay only produced when declining during car 9 is interval in bottom velocity variations in increase limiter of speed mechanism 100
Power, it is thus possible to significantly reduce the region that emergency braking device 15 carries out misoperation.
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 back-moving spring 45
Power and the viscosity of oil 46 are adjusted.
In addition, in embodiment 2,3, the 1st contact component 38 is configured to and additional mass body 41 or damping mechanism 42
Directly contact, but it is also possible to which the magnet repelled each other is set in contact surface.Thereby, it is possible to eliminate the impact produced with contact
Sound, makes passenger in car not produce discomfort.
Embodiment 4
Below, Figure 20 is the structure chart of the major part for the lift appliance for showing embodiments of the present invention 4.In embodiment party
In formula 4, replace the additional mass body 41 of embodiment 2, the bottom velocity variations that friction extensible guide 49 is arranged in hoistway 1 are interval
In.Friction extensible guide 49 abreast erects setting with car guide rail 11.
In addition, in embodiment 4, wedge structures 48 are set in connecting portion 23, replace the 1st contact site of embodiment 2
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
21 be the structure chart for the state for showing Figure 20 limiter of speed mechanism 100 and friction mechanism 60 in cage descending, and Figure 22 is to show
The structure chart of the state of limiter of speed mechanism 100 and friction mechanism 60 when car 9 rises from the state shown in Figure 21.
Below, Figure 23 is the top view for the friction mechanism 60 for showing Figure 20, and Figure 24 is along the XXIV-XXIV lines in Figure 23
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 guide members 52, multiple horizontal direction springs 53 and framework 54.
Friction chock 50 is configured to when car 9 is located at bottom velocity variations interval from sandwich friction extensible guide 49.
Drag wedge sub-spring 51 is between the bottom of friction chock 50 and framework 54.Friction chock 50 can pass through chock spring 51
It is flexible and move up and down.
The inclined plane guided to corresponding friction chock 50 is provided with each guide member 52.Horizontal direction spring 53
Between guide member 52 and framework 54.Guide member 52 can be moved by stretching for horizontal direction spring 53 to horizontal direction
It is dynamic.Other structures are identical with embodiment 1~3.
By the decline of car 9, in 48 insertion friction extensible guide 49 of wedge structures, friction chock 50 connects with friction extensible guide 49
