Further, since the first suppression component 21 and second of Sloshing suppression device 20 suppresses component 22 to the row of lift car 3 The inner side of the track (hereinafter referred to as " running rail ") sailed projects, so lift car 3 is possible to that component 21 can be suppressed with first Come in contact with the second suppression component 22.

Thus, during lift car 3 carries out lifting action, it is necessary to make the first of Sloshing suppression device 20 to suppress structure Part 21 and second suppresses component 22 to keep out of the way the outside of the running rail of lift car 3.In the present embodiment, using following side Method makes the first of Sloshing suppression device 20 suppress component 21 and second to suppress component 22 to keep out of the way the running rail of lift car 3 Outside.

First, as lift car 3 starts to lift (reference picture 12A and Figure 12 C), by connecting elements 16 and lift car The speed controller rope 15 of 3 connections is followed lift car 3 and is moved together.As shown in figure 9, the return side rope of speed controller rope 15 15b is subject to pressing for the active roller 41 of transmission mechanism 24.Therefore, active roller 41 is with the movement for returning side rope 15b Driving is pivoted about with the first transmission axle 42.

With the rotation driving of active roller 41, the revolving force of active roller 41 is via the first transmission pulley 43 and transfer tape 47 are passed to the second transmission pulley 46.Now, the second transmission pulley 46 pivots about driving with the second transmission axle 45. As shown in Figure 8 and Figure 9, due to being fixed with transmission clutch 44 on the second transmission pulley 46, so with the second transmission pulley 46 rotation, transmission clutch 44 carries out rotation driving.

With the faster rotational speed of transmission clutch 44, multiple expansions 44a and multiple weight part 44b (reference picture 7B) The active force of force application component 44c is overcome under the influence of centrifugal force and towards the outer side shifting of radial direction.Thus, clutch is transmitted The length in the radial direction of device 44 is expanded.Now, as shown in Figure 8 and Figure 9, multiple expansions of clutch 44 are transmitted 44a comes in contact with the rubbing surface 33a of the driven member 33 of backoff mechanism 23.Thus, the locomotivity conduct of side rope 15b is returned Revolving force is passed to backoff mechanism 23 from transmission mechanism 24.

By transmitting rotating force to driven member 33, driven member 33 and first turn be fixed on the driven member 33 Moving axis 31 overcome the elastic force of the first support spring 25a and the second support spring 25b and centered on bearing portions 32 (with reference to Fig. 3) Rotated.Therefore, first be fixed in the first rotary shaft 31 suppresses component 21 also with the rotation of the first rotary shaft 31 Rotate.

Additionally, the revolving force of the first rotary shaft 31 is passed in the presence of link gear 30 (with reference to Fig. 3 and Fig. 5) Two rotary shafts 36.Therefore, the second rotary shaft 36 and the second suppression component 22 being fixed in the second rotary shaft 36 start to rotate.Its As a result, as first suppresses component 21 and second to suppress the rotation of component 22, part 26 is suppressed to leave main hoist cable 4 or balance use Rope 14.

In addition, as shown in Figure 10, after driven member 33 rotates 90 degree, as shown in figure 11, the expansion of clutch 44 is transmitted The recess 33b of the embedded driven members 33 of component 44a.Also, transmit expansion 44a of clutch 44 and be arranged on recess 33b Swing roller 33c come in contact.Thus, the revolving force for transmitting clutch 44 is passed to swing roller 33c, makes swing roller 33c rotates.As a result, state shown in the state from Fig. 6 of driven member 33 becomes the state after rotating 90 degree and is maintained at the shape State.That is, the first rotary shaft 31 being fixed on driven member 33 is also held at the state after rotating 90 degree.Also, State after rotating 90 degree is also held at by the second rotary shaft 36 that link gear 30 is connected with the first rotary shaft 31.

After the first rotary shaft 31 and the second rotary shaft 36 rotate 90 degree, first suppresses component 21 and second to suppress component 22 cursor 27 moves to the state parallel with the wall of liftway 2.Thereby, it is possible to make the first suppression component 21 and second Suppress component 22 to keep out of the way the outside of the running rail of lift car 3, and can hold it in and keep out of the way outside running rail State behind side.Component 22 is suppressed to come in contact with the first suppression component 21 and second as a result, being prevented from lift car 3, So that Sloshing suppression device 21 will not hinder the traveling of lift car 3.

In the present embodiment, show making driven member 33, the first rotary shaft 31 and the second rotary shaft 36 rotate 90 degree Example is illustrated, but there is no need 90 degree be defined in strict implication in the present invention, only need to make the first suppression component 21 With the outside of the running rail that the second suppression component 22 keeps out of the way lift car 3.Therefore, driven member 33, first is rotated The rotational angle of the rotary shaft 36 of axle 31 and second can both be less than 90 degree, it is also possible to more than 90 degree.

During lift car 3 stops, the length started at from hoist engine 8 of main hoist cable 4 and balance rope 14 does not occur Change, so the natural period of main hoist cable 4 and balance rope 14 does not also change.Therefore, building structure and main hoist cable 4 Resonance is likely to occur with balance rope 14 and make winner's hoist cable 4 and balance rope 14 that big rocking to occur.Therefore, in electricity During terraced car 3 stops, it is necessary to being pressed down with rocking for rope 14 by 20 pairs of main hoist cables 4 of Sloshing suppression device and balance System.In the present embodiment, the first of Sloshing suppression device 20 is made to suppress component 21 and second to suppress component using following method The medial side of 22 running rails for being projected into lift car 3, thus suppressing rocking for main hoist cable 4 and balance rope 14.

First, after the stopping of lift car 3, the speed controller rope 15 for following the lifting action movement of lift car 3 also stops Only move.Therefore, while active roller 41 stops the rotation, transmission clutch 44 also stops the rotation.In transmission clutch 44 After stopping the rotation, as shown in Figure 7 A, the active force of multiple expansions 44a and multiple weight part 44b in force application component 44c It is mobile towards the side of the second transmission axle 45 (the namely inner side of radial direction) under effect.Thus, as shown in Figure 3 and Figure 6, transmit from Multiple expansions 44a of clutch 44 leave the rubbing surface 33a of driven member 33, between transmission clutch 44 and driven member 33 Produce gap.As a result, the power (revolving force) for being delivered to backoff mechanism 23 from transmission mechanism 24 is cut off.

After the transmission power transmitted from transmission mechanism 24 to driven member 33 is cut off, in the first support spring 25a and second In the presence of the recuperability of support spring 25b, cursor 27 is turned to and lifting from the state parallel with the wall of liftway 2 The orthogonal state of the wall of passage 2.Thus, the first rotary shaft 31 and the second rotary shaft 36 for being fixed with cursor 27 is rotated, and is made The state that also rotates to shown in Fig. 6 of driven member 33.

Also, as shown in Fig. 4 and Fig. 3, when the first suppression component 21 and second suppresses the cursor 27 of component 22 to turn to After horizontality, first suppress component 21 suppress part 26 and second suppress component 22 suppression part 26 and main hoist cable 4 or Person balances and is close to rope 14 or is contacted.Thus, the suppression that main hoist cable 4 or balance suppress component 21 with rope 14 by first Part 26 and second suppresses the suppression part 26 of component 22 to clamp such that it is able to suppress part 26,26 to suppress main by two Hoist cable 4 or balance rope 14 are rocked.

Because by making two to suppress parts 26,26 and main hoist cable 4, either balance is close to rope 14 or is contacted pressing down Rocking for main hoist cable 4 or balance rope 14 is made, so there is no need to constrain lift car 3 and balance weight 6 in vertical On displacement.As a result, it is strong with the connecting portion of main hoist cable 4 or balance rope 14 to there is no need raising lift car 3 Degree, also there is no need the radical for increasing main hoist cable 4 or balance rope 14.

As described above, in the Sloshing suppression device 20 of the present embodiment, suppressing as the first suppression component 21 and second is made Component 22 keeps out of the way the power of (rotation), produces when the lifting action for following lift car 3 using speed controller rope 15 is moved Power.Also, in order that first suppression component 21 and second suppress component 22 be projected in running rail from backoff state, with machine Tool mode cuts off the transmission power from transmission mechanism 24, and has used the first support spring 25a and the second support spring 25b Recuperability.Therefore, there is no need to carry out the electronics zero of action as driving force with electricity using motor, control section, sensor etc. Part can just make the first suppression component 21 and second suppress the action of component 22.

[relation between the direction of the lifting action of lift car and the direction of action of Sloshing suppression device]

Referring to Figure 12 between the direction of the lifting action of lift car 3 and the direction of action of Sloshing suppression device Relation is illustrated.

Figure 12 is suppression component 21, the explanatory diagram of 22 actions for representing lift car 3 and Sloshing suppression device 20.

As illustrated in fig. 12, when lift car 3 is moved towards top T1, the connecting side rope being connected with lift car 3 15a is moved as lift car 3 towards top T1.On the other hand, return side rope 15b towards with lift car 3 and be connected Side rope 15a contrary direction is lower section T2 movements.In the present embodiment, now, the first suppression structure of Sloshing suppression device 20 The suppression part 26 of the suppression component 22 of part 21 and second is from horizontality centered on the first rotary shaft 31 and the second rotary shaft 36 Rotate towards first direction R1 (upward).

As shown in Figure 12 B, when lift car 3 stops, the first suppression component 21 and second suppresses component 22 from keeping out of the way position Put towards second direction R2 and rotate.

Hereafter, as indicated in fig. 12 c, shown in lift car 3 from Figure 12 B be positioned against lower section T2 move when, connecting side Rope 15a is moved as lift car 3 towards lower section T2.On the other hand, return side rope 15b towards with connecting side rope The contrary direction of 15a and lift car 3 is top T1 movements.Now, first suppresses component 21 and second to suppress the suppression of component 22 Part processed 26 is respectively towards the second direction contrary with first direction R1 centered on the first rotary shaft 31 and the second rotary shaft 36 R2 (downward) is rotated.

Now, the first suppression component 21 and second suppresses the rotation direction of component 22 to follow the moving direction of lift car 3 Change and change.That is, when upward T1 is moved lift car 3, first suppresses component 21 and second to suppress structure The part 26 that suppresses of part 22 is rotated towards the moving direction identical direction with lift car 3.

Component 21 and second is suppressed to suppress the rotation direction of component 22 contrary with the moving direction of lift car 3 first When, the first suppression component 21 and second suppresses component 22 to be rotated towards lift car 3.Therefore, first suppresses component 21 May come in contact with lift car 3 with the second suppression component 22.

In contrast, in the present embodiment, first suppresses component 21 and second to suppress component 22 away from lift car 3 Direction rotate.Thus it is possible to prevent during the first suppression component 21 and second suppresses component 22 to carry out avoidance operation, electricity Terraced car 3 suppresses component 22 to come in contact with the first suppression component 21 and second.

According to the Sloshing suppression device 20 of the present embodiment, even if lift car 3 and first suppresses component 21 and second to suppress Component 22 comes in contact, because the first suppression component 21 and second suppresses component 22 to rotate, it is possible to producing when extenuating contact Impulsive force.In addition it is also possible to suppress to arrange buffer on component 22 in the first suppression component 21 and second.Thus, even if electric Terraced car 3 suppresses component 22 to come in contact with the first suppression component 21 and second, it is also possible to alleviate the impulsive force produced during contact.

The variation of the connecting elements of connection speed controller rope 15 and lift car 3 is illustrated referring to Figure 13.
