Suppress component 30 to be provided with 2 the 1st swings in swing and suppress component rope sheave 48, suppress component rope sheave 48 to be wrapping with the 1st in these the 1st swings and swing suppression component cable 49.1st swings suppression component one end of cable 49 is connected with winding rope sheave 47, and the other end (end of the opposition side of winding rope sheave 47 side) and the 1st swings and suppress component fixed part 50 to be connected.1st swings suppression component cable 49 suppresses component rope sheave 48 rearward to extend from the 1st swing, swings respectively suppress component fixed part 50 to be connected with winding rope sheave 47 and the 1st.

Suppress component 30 to be provided with 2 the 2nd swings in swing and suppress component rope sheave 51, suppress component rope sheave 51 to be wrapping with the 2nd in these the 2nd swings and swing suppression component cable 52.Swinging the 2nd suppresses component one end of cable 52 to connect swing suppression component bob-weight 53, and the other end (swinging the end suppressing component with the opposition side of bob-weight 53 side) and the 2nd swings and suppress component fixed part 54 to be connected.2nd swings suppression component cable 52 suppresses component rope sheave 51 forwards to extend from the 2nd swing, suppresses component to swing with bob-weight 53 and the 2nd respectively suppress component fixed part 54 to be connected with swing.In addition, suppress between component bob-weight 53, to be provided with swing suppression component bob-weight side rope sheave the 55,2nd swing suppression component cable 52 at the 2nd swing suppression component rope sheave 51 and swing to be wrapping with in swing suppression component bob-weight side rope sheave 55.2nd swings suppression component cable 52 suppresses component bob-weight side rope sheave 55 to extend downwards from swing.Thus, by swinging the deadweight suppressing component bob-weight 53, making the 2nd to swing and suppressing component cable 52 load tensioned.

By such formation, can swing to the 2nd at ordinary times and suppress component cable 52 to load (load) predetermined tension force, component 30 can be suppressed to load (load) power forwards to swing.Therefore, when the 1st swing suppresses component cable 49 to be released from winding rope sheave 47, swing can be made to suppress component 30 forwards to move.That is, between car 3 rising stage, winding rope sheave 47 is released the 1st and is swung suppression component cable 49, and swing can be made to suppress component 30 forwards to move.On the other hand, when the rope sheave 47 that reels reels the 1st swing suppression component cable 49, swing can be made to suppress component 30 rearward to move.That is, between car 3 decrement phase, winding rope sheave 47 reels and the 1st swings and suppress component cable 49, and swing can be made to suppress component 30 rearward to move.

Swing and suppress component 30 to suppress component guide rail 56 to guide in the longitudinal direction by swing described later.That is, as shown in FIG. 2 and 3, be respectively equipped with at the both ends swinging suppression component 30 swing extended in the vertical direction and suppress component directed section 31.Swing and suppress component directed section 31 to be installed on swing suppression component 30 via bracket 32.Suppressing component directed section 31 to be provided with the 1st above-mentioned swing in each swing suppresses component rope sheave the 48 and the 2nd to swing suppression component rope sheave 51.In the mode shown in Fig. 2 and Fig. 3, the swing of component rope sheave the 48 and the 2nd is suppressed to suppress component rope sheave 51 to form as one relative to swinging the 1st swing suppressing component 30 to be configured at same side.That is, be formed with 2 grooves at single rope sheave, be wrapping with the 1st at the groove of a side and swung suppression component cable 49, be wrapping with the 2nd at another square groove and swung suppression component cable 52.

As shown in Figure 2, suppress above component directed section 31 and below is provided with to swing and suppresses component guide rail 56 in each swing.Swing and suppress component guide rail 56 to be formed as extending in the longitudinal direction.The upper end of component directed section 31 and bottom is suppressed to be provided with wheel (roller) 57 each swing.Wheel 57 suppresses the surface scrolls of component guide rail 56 in the swing of correspondence.Like this, swinging suppression component 30 can suppress component directed section 31 and wheel 57 move smoothly while suppressing component guide rail 56 to guide in the longitudinal direction by swing via swing.

Component guide rail 56 is suppressed relative to swinging a pair swing suppressing component 30 to be configured at same side, be connected to each other by guide rail transom 58 in respective anterior end and rear end, a pair swing suppresses component guide rail 56 and pair of guide rails transom 58 to be formed as rectangular box-like as a whole.Be provided with at the guide rail transom 58 of rear side and swing for the 1st the through hole 59 suppressing component cable 49 through, be provided with at the guide rail transom 58 of front side and swing for the 2nd the through hole 60 suppressing component cable 52 through.

Bracket 61 is separately installed with at a pair car guide rail 10.Being fixed with above-mentioned winding rope sheave 47, worm gear 45 at bracket 61 and swinging suppresses component guide rail 56 etc. to form the component swinging and suppress component travel mechanism 40.

In addition, preferably swing dampening mechanism 30 and be positioned at the position more closer to the front than the lifting region 3a of this car 3 when car 3 is positioned at and swings and suppress the rational height of component 30.Thus, when car 3 be positioned at than swing suppress component 30 position more on the lower, swing can be made to suppress component 30 rearward to move and close to main rope 4, when car 3 is positioned at the position of side more top than swing suppression component 30, swing can be made to suppress component 30 to be positioned at the position more closer to the front than the lifting region 3a of car 3.Therefore, it is possible to avoiding car 3 and swinging the swing effectively suppressing main rope 4 while suppression component 30 is interfered.At this, the lifting region 3a of car 3 refers to the region extended in the vertical direction that the car 3 of lifting can pass through.

Then, be just described by such effect forming the present embodiment formed.

During car 3 declines in elevating road 2, with the decline of car 3 correspondingly, chain 42 is connected cable 43 loopy moving via chain, sprocket wheel 41 rotates in fig. 2 in the direction of the clock.Be accompanied by this, worm gear 45 rotates in the direction of the clock, rotates the winding gear 46 engaged rotate in the direction of the clock with worm gear 45.Thus, winding rope sheave 47 rotates in the direction of the clock, and the 1st swing suppression component cable 49 is wound rope sheave 47 and reels.

In this case, 1st swings suppression component cable 49 is wrapping with in swinging suppression component rope sheave 48 the swing the setting of suppression component 30 the 1st, and, 1st the other end swinging suppression component cable 49 is fixed on the 1st and is swung suppression component fixed part 50, therefore, swing suppresses component 30 to winding rope sheave 47 side, namely rearward moves.Therefore, swing and suppress component 30 close to main rope 4, main rope 4 and swing and suppress the distance between component 30 to reduce, thus the region that main rope 4 can swing can be reduced.Now, although suppress component bob-weight 53 to suppress component 30 to be loaded with power forwards swinging by swinging, the 1st swings and suppresses component cable 49 to overcome this power and be wound rope sheave 47 and reel.

On the other hand, the 2nd swings suppression component cable 52 is wrapping with in swinging suppression component rope sheave 51 the swing the setting of suppression component 30 the 2nd, and the 2nd the other end swinging suppression component cable 52 is fixed on the 2nd swing and is suppressed component fixed part 54.Therefore, between car 3 decrement phase, suppress the rearward movement of component 30 along with swing, swing and suppress component bob-weight 53 to rise.

During car 3 rises in elevating road 2, with the rising of car 3 correspondingly, chain 42 is connected cable 43 loopy moving via chain, sprocket wheel 41 is pressed anticlockwise direction in fig. 2 and is rotated.Be accompanied by this, worm gear 45 is pressed anticlockwise direction and is rotated, and rotates the winding gear 46 that engages press anticlockwise direction rotate together with the rope sheave 47 that reels with worm gear 45.

At this, the 2nd swings and suppresses component cable 52 to be suppressed component bob-weight 53 to be loaded with tension force by swing, suppresses component 30 to be loaded with power forwards swinging.Thus, the 1st swings suppression component cable 49 is released by from winding rope sheave 47, by swinging the 2nd the tension force suppressing component to load with cable 52, swinging suppression component 30 and suppressing component bob-weight 53 side to swing, namely forwards move.Therefore, swing and suppress component 30 away from main rope 4, arrive the front of the lifting region 3a of car 3.Car 3a and the swing that can avoid rising thus suppress component 30 to be interfered.

In addition, between car 3 rising stage, swing suppression component cable 49 by releasing the 1st from traction rope sheave, swing and suppress component bob-weight 53 to decline.

So according to the present embodiment, during car 3 rises, swing can be made to suppress component 30 forwards to move.Thereby, it is possible to make swing suppress component 30 to be positioned at the front of the lifting region 3a of car 3, car 3 and the swing that can avoid rising suppress component 30 to be interfered.In addition, during car 3 declines, swing can be made to suppress component 30 rearward to move.Thus, make swing suppress component 30 close to main rope 4, main rope 4 can be reduced and swing the distance suppressed between component 30, the region that main rope 4 can swing can be reduced.Even if that is, when car 3 lower floor, from car 3 to towing machine 6 the length of main rope 4 long, also can suppress the swing of main rope 4.In addition, suppress component 30 can be arranged at height desired in elevating road 2 owing to swinging, so can component 30 be suppressed to be arranged at the position that effectively can suppress the swing of main rope 4 swing.Its result, while can interfering car 3 avoiding (avoiding), even if the swing of the main rope 4 that also can effectively suppress when being arranged at high constructure.

(the 2nd embodiment)

Then, according to Fig. 4 to Fig. 7, the elevator rope with regard to second embodiment of the present invention swings suppression system and is described.

In the 2nd embodiment shown in Fig. 4 to Fig. 7, main difference is, swings and suppresses component to be moved in the longitudinal direction by collecting motor, and, suppressing the position relationship between component and car according to swinging, swinging and suppressing component rearward to move.Other formation is roughly the same with the 1st embodiment shown in Fig. 1 to Fig. 3.In addition, in Fig. 4 to Fig. 7, the label identical to the portion markings identical with the 1st embodiment shown in Fig. 1 to Fig. 3, omits detailed description.

As shown in FIG. 4 and 5, swing suppression component 30 to be moved in the longitudinal direction by collecting motor (winding drive division) 70.That is, the collecting motor 70 suppressing component travel mechanism 40 to have driving winding rope sheave 47 is swung.Thus, reel by driving collecting motor the 70,1st swing to suppress component cable 49 to be wound rope sheave 47 or release.This collecting motor 70 is installed on car guide rail 10 via bracket 61.

Swing in present embodiment suppresses component 30 can suppress to move freely in the longitudinal direction between position (with reference to Figure 13) at retreating position (with reference to Fig. 4) and swing, described retreating position is positioned at the position more closer to the front than the lifting region 3a of car 3, and described swing suppresses position to be positioned at position more more rearward than retreating position and more closer to the front than main rope 4.That is, when make swing suppress component 30 from retreating position move to swing suppress position, collecting motor 70 is made the 1st to swing to suppress component cable 49 to be wound rope sheave 47 to reel by driving.In addition, when making swing suppress component 30 to suppress position to move to retreating position from swing, collecting motor 70 is made the 1st swing suppress component cable 49 to be released by from winding rope sheave 47 by driving.

As shown in Figure 4, the high wind perceptron 72 of the earthquake perceptron 71 and perception high wind that are provided with perception earthquake in Machine Room 7 is used as perception unit.Wherein, earthquake perceptron 71, when perceiving earthquake, sends to control setup 12 by meaning the seismic signal 101 perceiving earthquake.Similarly, high wind perceptron 72, when perceiving high wind, sends to control setup 12 by meaning the high wind signal 102 perceiving high wind.

In addition, the position detecting device (car position detecting unit) 73 of the position detecting car 3 is provided with in Machine Room 7.Control setup 12 has arithmetic processing apparatus (car position judging unit) 74.Arithmetic processing apparatus 74 is when perceiving earthquake or when perceiving high wind by high wind perceptron 72 by earthquake perceptron 71, based on the position of the car 3 detected by device for detection of position of car body 73, judge whether car 3 is positioned at and suppress component 30 position more on the lower than swing.Arithmetic processing apparatus 74 suppresses the collecting motor 70 of component travel mechanism 40 to be connected via signal communication paths 75 with swing.In addition, arithmetic processing apparatus 74 is connected via not shown signal communication paths with device for detection of position of car body 73.

When arithmetic processing apparatus 74 be judged as car 3 be positioned at than swing suppress component 30 position more on the lower, swing and suppress component travel mechanism 40 to make swing suppress component 30 suppress position towards swing and rearward move.That is, in this case, collecting motor 70 rope sheave 47 that reeled by driving reels and the 1st swings and suppress component cable 49.Thus, swing and suppress component 30 rearward to move, arrive to swing and suppress position.

When the earthquake perceived or high wind become not perceived, swing and suppress component travel mechanism 40 to make swing suppress component 30 to suppress position forwards to be moved towards retreating position from swing.That is, in this case, collecting motor 70 is made the 1st swing suppress component cable 49 to be released by from winding rope sheave 47 by driving.Thus, swing and suppress component 30 forwards to move, arrive retreating position.

Swing and suppress component travel mechanism 40 also to have to suppress component 30 to reach to swing to suppress a pair swing detecting of position to suppress component detector switch (swing and suppress component detecting unit) 76 to swinging.Such as, the swing that the swing of a side suppresses component detector switch 76 can be installed on left side in Fig. 5 suppresses component guide rail 56, and the swing that the swing of the opposing party suppresses component detector switch 76 can be installed on right side suppresses component guide rail 56.When swinging suppression component 30 and arriving retreating position, each swing suppresses component directed section 31 to suppress component detector switch 76 to contact with corresponding swing, swings the action of suppression component detector switch, thus detects that swinging suppression component 30 reaches retreating position.Each swing suppresses component detector switch 76 to be connected with arithmetic processing apparatus 74 via not shown signal communication paths.When the swing by these two sides suppresses component detector switch 76 to detect that swing suppresses component 30 to reach swing suppression position, arithmetic processing apparatus 74 controls towing machine 6 to start to be elevated to make the car 3 stopped.

In addition, preferably: be judged as that car 3 is not positioned at than when swinging dampening mechanism 30 position more on the lower at arithmetic processing apparatus 74, even when perceiving earthquake or high wind, swing and suppressing component 30 also rearward not move.Component 30 is suppressed to be interfered thereby, it is possible to avoid car 3 and swing.

In addition, preferably: when being perceived earthquake by earthquake perceptron 71 or when perceiving high wind by high wind perceptron 72, arithmetic processing apparatus 74 controls towing machine 6 to make to stop the lifting of car 3.

Then, use Fig. 6 and Fig. 7, be just described by such effect forming the present embodiment formed.

First, earthquake perceptron 71, when perceiving earthquake, will represent that the seismic signal 101 of earthquake perception sends to the arithmetic processing apparatus 74(S11 of control setup 12).The seismic signal 101 sent is imported into input position < 1 > (bit < 1 >) of arithmetic processing apparatus 74 and inputs position < 2 >, and this input position < 1 > and input position < 2 > becomes 1 from 0 respectively.

Then, arithmetic processing apparatus 71 inputs car halt instruction 201 to towing machine 6 and stops (S12) to make the lifting of car 3.The towing machine 6 receiving car halt instruction 201 makes car 3 stop.Afterwards, confirm whether car 3 stops (S13).

On the other hand, the cage position signal 103 of the position representing car 3 is sent to arithmetic processing apparatus 74 by device for detection of position of car body 73.The cage position signal 103 sent is imported into input position < 0 > of arithmetic processing apparatus 74, and this input position < 0 > becomes 1 from 0.

After car 3 stops, the swing prestored suppresses the rational height of component 30 and the position of the car 3 represented by cage position signal 103 that sends from device for detection of position of car body 73 to compare by arithmetic processing apparatus 74, judges whether car 3 is positioned at than swing suppression component 30 position more on the lower (S14).

Arithmetic processing apparatus 74 when be judged as car 3 be positioned at than swing suppress component 30 position more on the lower, suppress the collecting motor 70 of component travel mechanism 40 to export the 1st driving instruction 202(S15 from carry out bit < 1 > of arithmetic processing apparatus 74 to swinging).The collecting motor 70 rotary actuation winding rope sheave 47 receiving the 1st driving instruction 202 suppresses component cable 49 with the 1st swing that reels.Thus, the 1st swing suppression component cable 49 is wound rope sheave 47 and reels, and swings and suppresses component 30 rearward move and arrive swing suppression position.Therefore, swing and suppress component 30 close to main rope 4, main rope 4 can be reduced and swing the distance suppressed between component 30.

When earthquake sense knows that the earthquake perception of device 71 is removed, input position < 1 > and input position < 2 > of arithmetic processing apparatus 74 become 0(S16 from 1).

Then, arithmetic processing apparatus 74 suppresses the collecting motor 70 of component travel mechanism 40 to export the 2nd driving instruction 203(S17 from its carry out bit < 2 > to swinging).The collecting motor 70 rotary actuation winding rope sheave 47 receiving the 2nd driving instruction 203 swings suppression component cable 52 to release the 2nd.Thus, the 2nd swings suppression component cable 52 is released by from winding rope sheave 47, swings and suppresses component 30 forwards move and arrive retreating position.Therefore, it is possible to the car 3 avoiding lifting suppresses component 30 to be interfered with swinging.

Then, be confirmed whether swing suppression component detector switch 76 action and suppress component detector switch 76 to have sent switch actuating signals 104(S18 to arithmetic processing apparatus 74 from swing).When suppressing component detector switch 76 to arithmetic processing apparatus 74 fire switch actuating signal 104 from the swing of two sides, input position < 3 >, input position < 4 >, this input position < 3 > and input position < 4 > that actuating signal 104 is imported into arithmetic processing apparatus 74 respectively become 1 from 0.

Afterwards, arithmetic processing apparatus 74 export from its carry out bit < 3 > to towing machine 6 car lifting instruction 204 be elevated (S19) to make car 3.Thus, usually run.In addition, when not receiving switch actuating signals 104 from least one swing in suppression component detector switch 76, preferred arithmetic processing apparatus 74 does not export car lifting instruction 204.

So according to the present embodiment, can when perceiving earthquake or high wind, car 3 be positioned at than swing suppress component 30 position more on the lower, make swing suppress component 30 to be positioned to swing to suppress position.Thereby, it is possible to make swing suppress component 30 close to main rope 4, main rope 4 can be reduced and swing the distance suppressed between component 30, the region that main rope 4 can swing can be reduced.Even if that is, be positioned at lower floor at car 3, long to the length of the main rope 4 of towing machine 6 from car 3, also can suppress the swing of main rope 4.In addition, the height desired by swing suppression component 30 can be arranged in elevating road 2, so can suppress component 30 be arranged at the position that effectively can suppress the swing of main rope 4 swing.Its result, can interfere while car 3, even if also effectively can suppress the swing of main rope 4 when being arranged at high constructure in avoidance.

In addition, according to the present embodiment, when the perception of earthquake or high wind is removed, swing can be made to suppress component 30 to be positioned at retreating position.In addition, when car 3 be not positioned at than swing suppress component 30 position more on the lower, swing can be made to suppress component 30 to be positioned at retreating position.Component 30 is suppressed to be interfered thereby, it is possible to avoid car 3 and swing.

(the 3rd embodiment)

Then, by Fig. 8 to Figure 10, swing suppression system with regard to the elevator rope in third embodiment of the present invention and be described.

In the 3rd embodiment shown in Fig. 8 to Figure 10, main difference point is that positions different is mutually provided with multiple swing suppression component on the lifting direction of car, and other formation is roughly the same with the 2nd embodiment shown in Fig. 4 to Fig. 7.In addition, in Fig. 8 to Figure 10, the label identical to the portion markings identical with the 2nd embodiment shown in Fig. 4 to Fig. 7, omits detailed description.

As shown in Figure 8, multiple (being 2 here) swings and suppresses component 30(30a, 30b) be located at positions different mutually on the lifting direction of car 3.Component 30a, 30b is suppressed to be provided with to make corresponding swing to suppress the swing of component 30a, 30b movement in the longitudinal direction to suppress component travel mechanism 40a, 40b each swing.

The arithmetic processing apparatus 74 of control setup 12, when perceiving earthquake or high wind, based on the position of the car 3 detected by device for detection of position of car body 73, is judged whether car 3 is positioned at and suppresses component 30a, 30b position more on the lower than each swing.When arithmetic processing apparatus 74 is judged as existing swing suppression component 30a, 30b of the position being configured at side more top than car 3, swings and suppress component travel mechanism 40a, 40b to make this swing suppress component 30a, 30b rearward to move towards swing suppression position.That is, arithmetic processing apparatus 74 controls collecting motor 70a, 70b and rearward moves to make the swing of the position being configured at side more top than car 3 suppress component 30a, 30b to suppress position towards swing.In addition, be configured at and suppress component 30a, 30b rearward not move than the swing of car 3 position more on the lower and maintain retreating position.

Then, use Fig. 9 and Figure 10, be just described by such effect forming the present embodiment formed.

First, earthquake perceptron 71, when perceiving earthquake, will represent that the seismic signal 101 of earthquake perception sends to the arithmetic processing apparatus 74(S21 of control setup 12).The seismic signal 101 sent is imported into input position < 1 > of arithmetic processing apparatus 74 and inputs position < 2 >, and this input position < 1 > and input position < 2 > becomes 1 from 0 respectively.

Then, arithmetic processing apparatus 74 exports car halt instruction 201 and stops (S22) to make the lifting of car 3 from its carry out bit < 0 > to towing machine 6.The towing machine 6 receiving car halt instruction 201 makes car 3 stop.Afterwards, confirm whether car 3 stops (S23).

On the other hand, the cage position signal 103 of the position representing car 3 is sent to arithmetic processing apparatus 74 by device for detection of position of car body 73.The cage position signal 103 sent is imported into input position < 0 > of arithmetic processing apparatus 74, and this input position < 0 > becomes 1 from 0.

After car 3 stops, arithmetic processing apparatus 74 by prestore each swing suppress the rational height of component 30a, 30b and send from device for detection of position of car body 73 cage position signal 103 represented by the position of car 3 compare, judge whether car 3 is positioned at than each swing suppression component 30a, 30b position more on the lower (S24).

Arithmetic processing apparatus 74 makes the swing being judged as the position being configured at side more top than car 3 suppress component 30a, 30b rearward to move (S25).

Specifically, arithmetic processing apparatus 74, when being judged as that the swing of upside suppresses the swing of component 30a and downside to suppress component 30b to be positioned at the position of side more top than car 3, suppresses collecting motor 70a, 70b of component travel mechanism 40a, 40b to export the 1st driving instruction 202 from carry out bit < 1 > of arithmetic processing apparatus 74 to each swing.Thus, each swing suppresses component 30a, 30b rearward move and arrive swing suppression position.

In addition, arithmetic processing apparatus 74, when being judged as that the swing of upside suppresses component 30a to be positioned at the position of side more top than car 3 but the swing of downside suppresses component 30b to be positioned at than car 3 position more on the lower, suppresses the swing that component 30a is corresponding to suppress the collecting motor 70a of component travel mechanism 40a to export the 1st driving instruction 202 from carry out bit < 1 > of arithmetic processing apparatus 74 to the swing of upside.Thus, the swing of upside suppresses component 30a rearward move and arrive swing suppression position.In addition, in this case, do not suppress the swing that component 30b is corresponding to suppress the collecting motor 70b of component travel mechanism 40b to export the 1st driving instruction to the swing of downside, the swing of downside suppresses component 30b to maintain retreating position.

Further, arithmetic processing apparatus 74 when be judged as each swing suppress component 30a, 30b to be all positioned at than car 3 position more on the lower, do not suppress collecting motor 70a, 70b of component travel mechanism 40a, 40b to export the 1st driving instruction 202 to each swing.Thus, each swing suppresses component 30a, 30b to maintain retreating position.

When earthquake sense knows that the earthquake perception of device 71 is removed, input position < 1 > and carry out bit < 2 > of arithmetic processing apparatus 74 become 0(S26 from 1).

Then, arithmetic processing apparatus 74 exports the 2nd driving instruction 203(S27 from its carry out bit < 2 > to the collecting motor 70 that have sent the 1st driving instruction 202).Thus, being positioned at the swing swinging suppression position suppresses component 30 forwards move and arrive retreating position.

Then, be confirmed whether swing suppression component detector switch 76a, 76b action and suppress component detector switch 76a, 76b to have sent switch actuating signals 104a, 104b(S28 to arithmetic processing apparatus 74 from swing).When suppressing component detector switch 76a to arithmetic processing apparatus 74 fire switch actuating signal 104a from the swing of two sides suppressing component 30a corresponding with the swing of upside, input position < 3 >, input position < 4 >, input position < 3 > and input position < 4 > that this switch actuating signals 104a is imported into arithmetic processing apparatus 74 respectively become 1 from 0.In addition, when suppressing component detector switch 76b to arithmetic processing apparatus 74 fire switch actuating signal 104b from the swing of two sides suppressing component 30b corresponding with the swing of downside, this switch actuating signals 104b is imported into input position < 5 >, input position < 6 > of arithmetic processing apparatus 74 respectively, inputs position < 5 >, input position < 6 > becomes 1 from 0.

Afterwards, arithmetic processing apparatus 74 export from its carry out bit < 3 > to towing machine 6 car lifting instruction 204 be elevated (S29) to make car 3.Thus, usually run.In addition, when not receiving switch actuating signals 104a, 104b from least one suppressing swing corresponding to component 30a, 30b to suppress in component detector switch 76a, 76b with the swing moving to retreating position, preferred arithmetic processing apparatus 74 does not export car lifting instruction 204.

So according to the present embodiment, on the lifting direction of car 3, different positions is provided with multiple swing suppression component 30a, 30b, the swing of the position being configured at side more top than car 3 can be made to suppress component 30a, 30b to be positioned at and swing suppression position.Thereby, it is possible to according to the position of car 3, make multiple swing suppress component 30a, 30b close to main rope 4, reduce main rope 4 and swing the distance suppressed between component 30a, 30b.In this case, because multiple swing suppresses component 30a, 30b to be located at positions different on the lifting direction of car 3, so the swing of main rope 4 can be suppressed in different positions, the swing of main rope 4 further can be suppressed.Therefore, though be positioned at lower floor at car 3, long to the length of the main rope 4 of towing machine 6 from car 3, also can suppress the swing of main rope 4.In addition, suppress component 30a, 30b can be arranged at height desired in elevating road 2 owing to swinging, so can component 30a, 30b be suppressed to be arranged at the position that effectively can suppress the swing of main rope 4 swing.Its result, can interfere while car 3, even if also effectively can suppress the swing of main rope 4 when being arranged at high constructure in avoidance.

In addition, according to the present embodiment, when the perception of earthquake or high wind is removed, swing can be made to suppress component 30a, 30b to be positioned at retreating position.In addition, swing suppression component 30a, the 30b be positioned at than car 3 position more on the lower can be made to be positioned at retreating position.Component 30a, 30b is suppressed to interfere thereby, it is possible to avoid car 3 and swing.

(the 4th embodiment)

Then, by Figure 11 to Figure 15, swing suppression system with regard to the elevator rope in fourth embodiment of the present invention and be described.

In the 4th embodiment shown in Figure 11 to Figure 15, main difference point is to suppress the position relationship between component and the bed of interest of car according to swinging, swinging and suppressing component rearward to move, and other formation is roughly the same with the 3rd embodiment shown in Fig. 8 to Figure 10.In addition, in Figure 11 to Figure 15, the label identical to the portion markings identical with the 3rd embodiment shown in Fig. 8 to Figure 10, omits detailed description.

As shown in figure 11, the bed of interest detecting device (bed of interest detecting unit) 80 of the bed of interest detecting car 3 is provided with in Machine Room 11.The arithmetic processing apparatus 74 of control setup 12 has the function as bed of interest judging unit.Namely, arithmetic processing apparatus 74 forms bed of interest judging unit, when being perceived earthquake by earthquake perceptron 71 or when perceiving high wind by high wind perceptron 72, based on the bed of interest of the car 3 detected by bed of interest detecting device 80, judge whether bed of interest (being supreme good layer when detecting multiple bed of interest) is positioned at and suppresses component 30a, 30b more on the lower than swing.In addition, arithmetic processing apparatus 74 is connected via not shown signal communication paths with bed of interest detecting device 80.

Arithmetic processing apparatus 74 is preferably when judging whether the bed of interest of car 3 is positioned at than swing suppression component 30a, 30b more on the lower, based on the position of the car 3 detected by device for detection of position of car body 73, judge whether car 3 is positioned at and suppress component 30a, 30b more on the lower than each swing.In this case, arithmetic processing apparatus 74 when be judged as existing be configured at suppress component 30a, 30b than the swing of the position of car 3 and the more top side of bed of interest thereof, make this swing suppress component 30a, 30b rearward to move towards midway location.That is, arithmetic processing apparatus 74 controls collecting motor 70a, 70b, suppresses component 30a, 30b rearward to move towards midway location to make the swing of the position being configured at side more top than car 3.In addition, be configured at and suppress component 30a, 30b rearward not to move than the swing of car 3 or its bed of interest position more on the lower and maintain retreating position.At this, midway location refers to retreating position as shown in figure 12 and swings the position suppressed between position.Preferred midway location is retreating position and the position swinging the central authorities suppressed between position.Figure 13 represents that swing suppresses position.

After car 3 arrives bed of interest, swing corresponding to component 30a, 30b is suppressed to suppress component travel mechanism 40a, 40b to make this swing suppress component 30a, 30b suppress position towards swinging and rearward move with the swing reaching midway location.Thus, rearward move and the swing that arrives midway location suppresses component 30a, 30b rearward to move further and arrive to swing and suppress position.In addition, now, arithmetic processing apparatus 74 controls towing machine 6 to stop the lifting of car 3.

In addition, when arithmetic processing apparatus 74 is judged as that the bed of interest of car 3 is not positioned at than swing suppression component 30a, 30b more on the lower, even preferably when perceiving earthquake or high wind, swinging and suppressing component travel mechanism 40a, 40b also not to make swing suppress component 30a, 30b to move.Component 30a, 30b is suppressed to interfere thereby, it is possible to avoid car 3 and swing.

In addition, preferably accepting of the bed of interest of car 3 is stopped when perceiving earthquake or high wind.Component 30a, 30b is suppressed to interfere thereby, it is possible to avoid car 3 and swing.

Then, use Figure 14 and Figure 15, be just described by such effect forming the present embodiment formed.

First, earthquake perceptron 17, when perceiving earthquake, will represent that the seismic signal 101 of earthquake perception sends to the arithmetic processing apparatus 74(S31 of control setup 12).The seismic signal 101 sent is imported into input position < 1 > of arithmetic processing apparatus 74 and inputs position < 2 >, and this input position < 1 > and input position < 2 > becomes 1 from 0 respectively.

Then, what arithmetic processing apparatus 74 made the bed of interest of car 3 accepts stopping (S32).

On the other hand, the cage position signal 103 of the position representing car 3 is sent to arithmetic processing apparatus 74 by device for detection of position of car body 73.The cage position signal 103 sent is imported into input position < 0 > of arithmetic processing apparatus 74, and this input position < 0 > becomes 1 from 0.

In addition, the bed of interest signal 105 of the bed of interest representing car 3 is sent to arithmetic processing apparatus 74 by bed of interest detecting device 80.The bed of interest signal 105 sent is imported into input position < 5 > of arithmetic processing apparatus 74, and this input position < 5 > becomes 1 from 0.

Then, arithmetic processing apparatus 74 by arrange each swing suppress the position of component 30a, 30b and send from bed of interest detecting device 80 bed of interest signal 105 represented by the bed of interest of car 3 compare, judge whether bed of interest is positioned at than each swing suppression component 30a, 30b more on the lower (S34).Now, preferred arithmetic processing apparatus 74 by prestore each swing suppress the rational height of component 30a, 30b and send from device for detection of position of car body 73 cage position signal 103 represented by the position of car 3 compare, judge whether car 3 is positioned at than each swing suppression component 30a, 30b more on the lower.

Arithmetic processing apparatus 74 makes the position that is judged as being configured at than the more top side of car 3 and the swing being configured at the position of side more top than the bed of interest of car 3 suppresses component 30a, 30b rearward to move (S35).

Specifically, arithmetic processing apparatus 74, when being judged as the position that the swing of upside suppresses the swing of component 30a and downside to suppress component 30b to be positioned at than car 3 and the more top side of bed of interest thereof, suppresses collecting motor 70a, 70b of component travel mechanism 40a, 40b to export the 3rd driving instruction 205 from carry out bit < 1 > of arithmetic processing apparatus 74 to each swing.Thus, each swing suppresses component 30a, 30b rearward move and arrive midway location.

In addition, arithmetic processing apparatus 74, when being judged as that the swing of upside suppresses component 30a to be positioned at position than car 3 and the more top side of bed of interest thereof but the swing of downside suppresses component 30b to be positioned at than car 3 and bed of interest thereof position more on the lower, suppresses the swing that component 30a is corresponding to suppress the collecting motor 70a of component travel mechanism 40a to export the 3rd driving instruction 205 from carry out bit < 1 > of arithmetic processing apparatus 74 to the swing of upside.Thus, the swing of upside suppresses component 30a rearward move and arrive midway location.In addition, in this case, do not suppress the swing that component 30b is corresponding to suppress the collecting motor 70b of component travel mechanism 40b to export the 3rd driving instruction 205 to the swing of downside, the swing of downside suppresses component 30b to maintain retreating position.

Further, arithmetic processing apparatus 74 when be judged as each swing suppress component 30a, 30b to be all positioned at than car 3 and bed of interest thereof position more on the lower, do not suppress collecting motor 70a, 70b of component travel mechanism 40a, 40b to export the 3rd driving instruction 205 to each swing.Thus, each swing suppresses component 30a, 30b to maintain retreating position.

Afterwards, be confirmed whether that car 3 arrives bed of interest and stops (S36).

When car 3 stops, arithmetic processing apparatus 74 exports the 4th driving instruction 206(S37 to collecting motor 70a, the 70b that have sent the 3rd driving instruction 205).Thus, the swing being positioned at midway location suppresses component 30a, 30b rearward to move further, arrives to swing and suppresses position.

When earthquake sense knows that the earthquake perception of device 71 is removed, input position < 1 > and input position < 2 > of arithmetic processing apparatus 74 become 0(S38 from 1).

Then, arithmetic processing apparatus 74 exports the 5th driving instruction 207(S39 from its carry out bit < 2 > to collecting motor 70a, the 70b that have sent the 4th driving instruction 206).Thus, be positioned to swing and suppress the swing of position to suppress component 30a, 30b forwards to move, arrive retreating position.

Then, be confirmed whether swing suppression component detector switch 76a, 76b action and suppress component detector switch 76a, 76b to have sent switch actuating signals 104a, 104b(S40 to arithmetic processing apparatus 74 from swing).When suppressing component detector switch 76a to arithmetic processing apparatus 74 fire switch actuating signal 104a from the swing of two sides suppressing component 30a corresponding with the swing of upside, input position < 3 >, input position < 4 >, input position < 3 > and input position < 4 > that this switch actuating signals 104a is imported into arithmetic processing apparatus 74 respectively become 1 from 0.In addition, when suppressing component detector switch 76b to arithmetic processing apparatus 74 fire switch actuating signal 104b from the swing of two sides suppressing component 30b corresponding with the swing of downside, input position < 5 >, input position < 6 >, input position < 5 > and input position < 6 > that this switch actuating signals 104b is imported into arithmetic processing apparatus 74 respectively become 1 from 0.

Afterwards, arithmetic processing apparatus 74 export from its carry out bit < 3 > to towing machine 6 car lifting instruction 204 be elevated (S41) to make car 3.Thus, usually run.In addition, when not receiving switch actuating signals 104a, 104b from least one suppressing swing corresponding to component 30a, 30b to suppress in component detector switch 76a, 76b with the swing moving to retreating position, preferred arithmetic processing apparatus 74 does not export car lifting instruction 204.

So according to the present embodiment, can when perceive earthquake or high wind and the bed of interest of car 3 be positioned at suppress component 30a, 30b more on the lower than swing, make swing suppress component 30a, 30b to move to midway location.Thereby, it is possible to make swing suppress component 30a, 30b close to main rope 4, reduce main rope 4 and swing the distance suppressed between component 30a, 30b, the region that main rope 4 can swing can be reduced.In addition, swing suppression component 30a, 30b owing to being positioned at midway location are positioned at than swinging the position suppressing position closer to the front, so can prevent from swinging the obstacle suppressing component 30a, 30b to become car 3 lifting.Therefore, it is possible to suppress the swing of main rope 4 while making car 3 be elevated.

In addition, according to the present embodiment, after car 3 arrives bed of interest, the swing of arrival midway location can be made to suppress component 30a, 30b to move to and to swing suppression position.Thereby, it is possible to make swing suppress component 30a, 30b further close to main rope 4, the swing of main rope 4 further can be suppressed.

In addition, according to the present embodiment, on the lifting direction of car 3, different positions is provided with multiple swing suppression component 30a, 30b, the swing of the position being configured at side more top than the bed of interest of car 3 can be made to suppress component 30a, 30b to be positioned at and swing suppression position.Thereby, it is possible to the floor of bed of interest according to car 3, make multiple swing suppress component 30a, 30b close to main rope 4, reduce main rope 4 and swing the distance suppressed between component 30a, 30b, simultaneously elevator car 3.In this case, because multiple swing suppresses component 30a, 30b to be located at positions different on the lifting direction of car 3, so the swing of main rope 4 can be suppressed in different positions, the swing of main rope 4 further can be suppressed.Even if that is, when car 3 lower floor, from car 3 to towing machine 6 the length of main rope 4 long, also can suppress the swing of main rope 4.In addition, suppress component 30a, 30b can be arranged at height desired in elevating road 2 owing to swinging, so can component 30a, 30b be suppressed to be arranged at the position that effectively can suppress the swing of main rope 4 swing.Its result, can interfere while car 3, even if also effectively can suppress the swing of main rope 4 when being arranged at high constructure in avoidance.

(the 5th embodiment)

Then, according to Figure 16 to Figure 18, the elevator rope with regard to fifth embodiment of the present invention swings suppression system and is described.

In the 5th embodiment shown in Figure 16 to Figure 18, main difference point is and earthquake, high wind have nothing to do and suppresses the position between component and car to make swing suppress component rearward to move according to swinging, and other formation is roughly the same with the 3rd embodiment shown in Fig. 8 to Figure 10.In addition, in Figure 16 to Figure 18, to the label identical with the identical portion markings of the 3rd embodiment shown in Figure 18 to Figure 10, omit detailed description.

As shown in figure 16, multiple (being 3 here) swings and suppresses component 30(30a, 30b, 30c) be located at positions different on the lifting direction of car 3.Component 30a, 30b, 30c is suppressed to be provided with to make corresponding swing to suppress the swing of component 30a, 30b, 30c movement in the longitudinal direction to suppress component travel mechanism 40a, 40b, 40c each swing.In addition, in the present embodiment, whether with perception earthquake, high wind have nothing to do, and when making swing suppress component 30a, 30b, 30c rearward to move, car 3 is also elevated.That is, the swing of main rope 4 can be suppressed while making car 3 be elevated.

Use Figure 17 and Figure 18, the effect that the elevator rope with regard to present embodiment swings suppression system 20 is described.

Here, situation about first rising from orlop to the superiors for car 3 is described.

Device for detection of position of car body 73 will represent that the cage position signal 103 being positioned at the position of undermost car 3 sends to arithmetic processing apparatus 74.The cage position signal 103 sent is imported into input position < 0 > of arithmetic processing apparatus 74, and this input position < 0 > becomes 1 from 0.

Then, arithmetic processing apparatus 74 by prestore each swing suppress the rational height of component 30a, 30b, 30c and send from device for detection of position of car body 73 cage position signal 103 represented by the position of car 3 compare, judge whether car 3 is positioned at than each swing suppression component 30a, 30b, 30c position more on the lower (S51).

Because car 3 is positioned at orlop, so arithmetic processing apparatus 74 is judged as that 3 swing the position suppressing component 30a, 30b, 30c to be positioned at side more top than car 3, collecting motor 70a, 70b, 70c of component travel mechanism 40a, 40b, 40c is suppressed to export the 6th driving instruction 208(S52 from carry out bit < 1 > of arithmetic processing apparatus 74 to each swing).Thus, each swing suppresses component 30a, 30b, 30c rearward to move, and arrives midway location.

During car 3 rises from orlop to the superiors, send cage position signal 103 from device for detection of position of car body 73 to arithmetic processing apparatus 74.

During this period, arithmetic processing apparatus 74 by prestore each swing suppress the rational height of component 30a, 30b, 30c and send from device for detection of position of car body 73 cage position signal 103 represented by the position of car 3 compare, judge whether car 3 is positioned at than each swing suppression component 30a, 30b, 30c position more on the lower (S51).Specifically, arithmetic processing apparatus 74 judges whether car 3 is positioned at than each position (namely relative to each position swinging that suppress component 30a, 30b, 30c, that downside is predetermined distance) swinging the distance suppressing component 30a, 30b, 30c predetermined to downside, and judges whether the car 3 risen suppresses component 30a, 30b, 30c by each swing.

When being judged as that the swing of car 3 by downside suppresses component 30b, arithmetic processing apparatus 74 suppresses the swing that component 30b is corresponding to suppress the collecting motor 70b of component travel mechanism 40b to export the 7th driving instruction 209(S53 from carry out bit < 2 > of arithmetic processing apparatus 74 to the swing of downside).Thus, the swing of downside suppresses component 30b forwards move and arrive retreating position, and the swing can avoiding car 3 and downside suppresses the interference between component 30b.

Then, be confirmed whether swing suppression component detector switch 76b action and suppress component detector switch 76b to have sent switch actuating signals 104b(S54 to arithmetic processing apparatus 74 from swing).When suppressing component detector switch 76b to arithmetic processing apparatus 74 fire switch actuating signal 104b from the swing of two sides suppressing component 30b corresponding with the swing of downside, this switch actuating signals 104b is imported into input position < 8 > and input position < 9 > of arithmetic processing apparatus 74, inputs position < 8 > and input position < 9 > to become 1 from 0.

In addition, when swinging suppression component 30b and arriving retreating position, when at least one suppression from the swing of correspondence in component detector switch 76b does not have to arithmetic processing apparatus 74 fire switch actuating signal 104b, export car halt instruction 201 from carry out bit < 0 > of arithmetic processing apparatus 74 to towing machine 6, car 3 stops.

The swing that have passed downside suppresses the car 3 of component 30b to continue further to rise.During this period, send cage position signal 103 from device for detection of position of car body 73 to arithmetic processing apparatus 74, arithmetic processing apparatus 74 judges whether the car 3 risen suppresses component 30a, 30b, 30c(S51 by each swing).

When being judged as car 3 by middle swing suppression component 30c, arithmetic processing apparatus 74 suppresses the swing that component 30c is corresponding to suppress the collecting motor 70c of component travel mechanism 40c to send the 7th driving instruction 209(S53 from carry out bit < 2 > of arithmetic processing apparatus 74 to the swing of centre).Thus, middle swing suppresses component 30c forwards move and arrive retreating position, thus the swing can avoiding car 3 and centre suppresses the interference between component 30c.

Then, be confirmed whether swing suppression component detector switch 76c action and suppress component detector switch 76c to have sent switch actuating signals 104c(S54 to arithmetic processing apparatus 74 from swing).When suppressing component detector switch 76c to arithmetic processing apparatus 74 fire switch actuating signal 104c from the swing of two sides suppressing component 30c corresponding with the swing of centre, this switch actuating signals 104c is imported into input position < 6 > and input position < 7 > of arithmetic processing apparatus 74, inputs position < 6 > and input position < 7 > to become 1 from 0.

In addition, when swinging suppression component 30c and arriving retreating position, when suppressing component detector switch 76c not to arithmetic processing apparatus 74 fire switch actuating signal 104c from the swing of correspondence, send car halt instruction 201 from carry out bit < 0 > of arithmetic processing apparatus 74 to towing machine 6, car 3 stops.

Have passed middle swing suppresses the car 3 of component 30c to continue further to rise.During this period, send cage position signal 103 from device for detection of position of car body 73 to arithmetic processing apparatus 74, arithmetic processing apparatus 74 judges whether the car 3 risen suppresses component 30a, 30b, 30c(S51 by each swing).

When being judged as that the swing of car 3 by upside suppresses component 30a, arithmetic processing apparatus 74 suppresses the swing that component 30a is corresponding to suppress the collecting motor 70a of component travel mechanism 40a to send the 7th driving instruction 209(S53 from carry out bit < 2 > of arithmetic processing apparatus 74 to the swing of upside).Thus, the swing of upside suppresses component 30a forwards move and arrive retreating position, thus the swing can avoiding car 3 and upside suppresses the interference between component 30a.

Then, be confirmed whether swing suppression component detector switch 76 action and suppress component detector switch 76a to have sent switch actuating signals 104a(S54 to arithmetic processing apparatus 74 from swing).When suppressing component detector switch 76a to arithmetic processing apparatus 74 fire switch actuating signal 104a from the swing of two sides suppressing component 40a corresponding with the swing of upside, this switch actuating signals 104a is imported into input position < 3 > and input position < 4 > of arithmetic processing apparatus 74.Input position < 3 > and input position < 4 > that are transfused to switch actuating signals 104 become 1 from 0.

In addition, when swinging suppression component 30a and arriving retreating position, when suppressing component detector switch 76a not to arithmetic processing apparatus 74 fire switch actuating signal 104a from the swing of correspondence, send car halt instruction 201 from carry out bit < 0 > of arithmetic processing apparatus 74 to towing machine 6, car 3 stops.

Then, situation about declining from the superiors to orlop for car 3 is described.

Device for detection of position of car body 73 will represent that the cage position signal 103 being positioned at the position of the car 3 of the superiors sends to arithmetic processing apparatus 74.The cage position signal 103 sent is imported into input position < 0 > of arithmetic processing apparatus 74, and this input position < 0 > becomes 1 from 0.

Then, arithmetic processing apparatus 74 by prestore each swing suppress the rational height of component 30a, 30b, 30c and send from device for detection of position of car body 73 cage position signal 103 represented by the position of car 3 compare, judge whether car 3 is positioned at than each swing suppression component 30a, 30b, 30c position more on the lower (S51).

Because car 3 is positioned at the superiors, so arithmetic processing apparatus 74 is judged as that 3 swings suppress component 30a, 30b, 30c to be all positioned at than car 3 position more on the lower, do not export the 6th driving instruction 208.In this case, each swing suppresses component 30a, 30b, 30c to be all positioned at retreating position.

During car 3 declines from the superiors to orlop, send cage position signal 103 from device for detection of position of car body 73 to arithmetic processing apparatus 74.

During this period, arithmetic processing apparatus 74 by prestore each swing suppress the rational height of component 30a, 30b, 30c and send from device for detection of position of car body 73 cage position signal 103 represented by the position of car 3 compare, judge whether car 3 is positioned at than each swing suppression component 30a, 30b, 30c position more on the lower (S51).Specifically, arithmetic processing apparatus 74 judges whether car 3 is positioned at from each position swinging the distance suppressing component 30a, 30b, 30c predetermined downwards, and judges whether the car 3 declined have passed each swing and suppress component 30a, 30b, 30c.

When being judged as that car 3 have passed the swing suppression component 30a of upside, arithmetic processing apparatus 74 suppresses the swing that component 30a is corresponding to suppress the collecting motor 70a of component travel mechanism 40a to export the 6th driving instruction 208(S52 from carry out bit < 2 > of arithmetic processing apparatus 74 to the swing of upside).Thus, the swing of upside suppresses component 30a rearward move and arrive midway location, thus the swing can avoiding car 3 and upside suppresses the interference between component 30a.

The swing that have passed upside suppresses the car 3 of component 30a to continue further to decline.During this period, send cage position signal 103 from device for detection of position of car body 73 to arithmetic processing apparatus 74, arithmetic processing apparatus judges whether the car 3 declined have passed each swing and suppress component 30a, 30b, 30c(S51).

When being judged as that car 3 have passed middle swing suppression component 30c, arithmetic processing apparatus 74 suppresses the swing that component 30c is corresponding to suppress the collecting motor 70c of component travel mechanism 40c to export the 6th driving instruction (S52) from carry out bit < 0 > of arithmetic processing apparatus 74 to the swing of centre.Thus, middle swing suppresses component 30c rearward move and arrive midway location, thus the swing can avoiding car 3 and centre suppresses the interference between component 30c.

Have passed middle swing suppresses the car 3 of structure 30c to continue further to decline.During this period, send cage position signal 103 from device for detection of position of car body 73 to arithmetic processing apparatus 74, arithmetic processing apparatus 74 judges whether the car 3 declined have passed each swing and suppress component 30a, 30b, 30c(S51).

When being judged as that car 3 have passed the swing suppression component 30b of downside, arithmetic processing apparatus 74 suppresses the swing that component 30b is corresponding to suppress the collecting motor 70b of component travel mechanism 40b to export the 6th driving instruction 208(S51 from carry out bit < 2 > of arithmetic processing apparatus 74 to the swing of downside).Thus, the swing of downside suppresses component 30b rearward move and arrive midway location, thus the swing can avoiding car 3 and downside suppresses the interference between component 30b.

So according to the present embodiment, can and earthquake, high wind have nothing to do and suppress the position relationship between component 30a, 30b, 30c and car 3 to make swing suppress component 30a, 30b, 30c close to main rope 4 according to swinging.Thereby, it is possible to while avoidance swings and suppresses component 30a, 30b, 30c and car 3 to be interfered, reduce main rope 4 and swing the distance suppressed between component 30a, 30b, 30c, thus the region that main rope 4 can swing can be reduced.In addition, because the swing being positioned at midway location suppresses component 30a, 30b, 30c to be positioned at than swinging the position suppressing position closer to the front, so can prevent from swinging the obstacle suppressing component 30a, 30b, 30c to become the lifting of car 3.Thereby, it is possible to suppress the swing of main rope 4 while making car 3 be elevated.

In addition, according to the present embodiment, on the lifting direction of car 3, positions different is mutually provided with multiple swing suppression component 30a, 30b, 30c, and the swing of the position being configured at side more top than car 3 can be made to suppress component 30a, 30b, 30c to be positioned at midway location.Thereby, it is possible to according to the position of car 3, make multiple swing suppress component 30a, 30b, 30c close to main rope 4, can, while reducing main rope 4 and swinging the distance that suppresses between component 30a, 30b, 30c, car 3 is elevated.In this case, because multiple swing suppresses component 30a, 30b, 30c to be located at positions different mutually on the lifting direction of car 3, so the swing of main rope 4 can be suppressed in different positions, thus the swing of main rope 4 further can be suppressed.Therefore, though when car 3 lower floor, from car 3 to towing machine 6 the length of main rope 4 long, also can suppress the swing of main rope 4.In addition, suppress component 30a, 30b can be arranged at height desired in elevating road 2 owing to swinging, so can component 30a, 30b be suppressed to be arranged at the position that effectively can suppress the swing of main rope 4 swing.Its result, can interfere while car 3, even if also effectively can suppress the swing of main rope 4 when being arranged at high constructure in avoidance.
