Technical field
The present invention relates to possess and linking the rope of car with bob-weight is used to detect this situation under the situation of runout above allowed value the elevator device that intersects detecting device.
Background technology
Elevator device possesses many main ropes (main rope) and many compensates rope (compensation rope) respectively as the rope that car and bob-weight are linked.Main rope hangs on the main rope sheave (main sheave) of winch, and car and bob-weight are linked with bucket type.Compensates rope is suspended between car and the bob-weight.Compensates rope is the center with main rope, and the weight of the main rope between cage side and the bob-weight side uneven situation that becomes corresponding to the position of car is offset.In these ropes, use the wirerope (wire rope) of steel.Many ropes are in order to be arranged as a row configuration through rope sheave.
The elevator of high-rise mansion is longer with the distance that the elevator of middle low layer mansion is compared hoistway, so rope receives influence and the runout easily of waving of building or wind.If the degree that the rope runout contacts with each other or intersects to adjacent rope then has rope possibly under the state that intersects, pass through main rope sheave or compensating rope sheave (compensation sheave).If rope through main rope sheave or compensating rope sheave, is then worried adjacent rope transposing under the state that intersects.In order to make adjacent rope each other not in contact physically, what enlarge rope is actv. at interval.But, if consider and the layout relationship of other equipment that the space that then in fact can guarantee is restricted.
The elevator device that is provided with the runout detecting device that is used for detecting earlier the rope runout is arranged.The runout detecting device has the roller of the both sides of the amplitude that is configured in rope.Roller rope with the situation of stipulating above amplitude runout under, through contact the runout that suppresses rope with rope.In addition, displacement ground is supported under the situation of the rope pushing that contacts receiving of roller.The runout detecting device possesses that measuring roll surpasses predefined amount and the switch of the situation of displacement.If elevator device detects the signal of switch, car is stopped.
, the pattern during the rope runout is divided into two kinds substantially.The 1st pattern is the state that is arranged as messy ground of the rope difference runout of row, and the 2nd pattern is the states of whole ropes to the identical synchronous runout of direction.Under the situation of the 2nd pattern, the situation that rope contacts with each other seldom.Thereby, want to detect energetically that rope contacts with each other or the runout of the 1st pattern that the possibility of intersecting is bigger.
But runout detecting device does not up to the present constitute the 1st pattern and the difference of the 2nd pattern is detected.If the switch of installation and measuring displacement on each roller, then might be able to differentiate with the 1st pattern runout still is with the 2nd pattern runout.But the quantity that just increases switch will spend cost.And then, pass through to so far device difficult and be with the 2nd pattern runout, or the differentiation that intersects of rope.
In addition, the moving velocity of general car is that the elevator device that in high-rise mansion, adopts is faster, thereby the moving velocity of main rope and compensates rope is also faster.In such elevator device, if rope intersects, the part former state of then intersecting is passed through main rope sheave and compensating rope sheave in a flash.
Summary of the invention
So the present invention provides a kind of elevator device that possesses the intersection detecting device of the situation that detects the rope intersection reliably.
The elevator device of one technical scheme possesses: rope, and many are arranged in parallel is that row dispose, between from the car to the bob-weight; Rope sheave disposes for the direction that changes the rope of trying to stop people from fighting each other; And the intersection detecting device, be configured in rope sheave near.And the detecting device that intersects possesses the 1st measuring roll and the 2nd measuring roll, the 1st arm and the 2nd arm, bar and test section.The 1st measuring roll and the 2nd measuring roll are configured to a pair of in the face of what claim with respect to classifying as of rope.The 1st arm and the 2nd arm support the 1st measuring roll and the 2nd measuring roll respectively with the mode of the direction displacement of the row of wire rope handling rope sidelong.Bar keeps the 1st arm and the 2nd arm so that the interval between the 1st measuring roll and the 2nd measuring roll becomes the mode below 2 times of the diameter of rope.Test section detects the situation that the 1st measuring roll and the 2nd measuring roll leave.
According to the elevator device of said structure, can detect the situation that rope intersects reliably.

The specific embodiment
The elevator device 1 of the 1st embodiment is described referring to figs. 1 through Figure 13.Elevator device 1 shown in Figure 1 possesses winch 3, car 4, bob-weight 5, main rope 6, compensates rope 7, main rope sheave 31, compensating rope sheave 71 and the detecting device 10 that intersects.This elevator device 1 possesses Machine Room 201 above hoistway 200.In Machine Room 201, be provided with winch 3 and control panel 202.Main rope sheave 31 is installed on the output shaft of winch 3, and volume is hung main rope 6.Car 4 and bob-weight 5 are suspended on the main rope 6, move along the guide rail that is arranged in the hoistway 200 vertically.Compensates rope 7 is rolled up on the compensating rope sheave 71 in the pit 203 that hangs over the bottom that is disposed at hoistway 200 from the bottom suspention of car 4 and bob-weight 5.
The detecting device 10 that intersects be configured in respectively Fig. 1 and compensating rope sheave 71 shown in Figure 2 near and Fig. 1 and main rope sheave 31 shown in Figure 3 and track adjusting wheel 32 near.Near the intersection detecting device 10 that is configured in compensating rope sheave 71 is as shown in Figure 2, is installed in the top of the housing 72 that surrounds compensating rope sheave 71.Housing 72 possesses the guidance device 74 on the guide rail 73 that is entrenched in compensating rope sheave 71 usefulness that are arranged in the pit 203, moves to vertical direction along guide rail 73.In addition, near the intersection detecting device 10 that is configured in main rope sheave 31 and track adjusting wheel 32 is as shown in Figure 3, is installed on the lower surface of the beam that constitutes the support 33 that supports winch 3 and track adjusting wheel 32.
These intersection detecting devices 10 all are identical structures, so as representative near the intersection detecting device 10 that is configured in compensating rope sheave 71 is described.This intersects detecting device 10 like Fig. 4 and shown in Figure 5, possesses framework the 11, the 1st measuring roll 12A, the 2nd measuring roll 12B, the 1st arm 13A, the 2nd arm 13B, bar 14, inhibition spring (suppressing ス プ リ Application グ) 15, neutral spring (neutral ス プ リ Application グ) 16 and test section 17.Framework 11 forms, and makes its encirclement be arranged as 5 compensates rope 7 of row.
The 1st measuring roll 12A and the 2nd measuring roll 12B dispose a pair of on the position away from compensates rope 7 with the face at the center of classifying as of compensates rope 7 symmetrically.With under than the situation of allowing the amplitude runout that amplitude is big, the 1st measuring roll 12A and the 2nd measuring roll 12B contact with compensates rope 7 in compensates rope 7.In this embodiment, what is called is allowed the amplitude of the Uncrossed degree of rope, and the amplitude of the rope that is rope when intersecting detecting device 10 is below 2 times of diameter of rope.Thereby the interval S that kind as shown in Figure 5 of the 1st measuring roll 12A and the 2nd measuring roll 12B is set to below 2 times of diameter d of compensates rope 7.The 1st measuring roll 12A and the 2nd measuring roll 12B have the axle 121 that extends from two ends via bearing respectively.
The outer surface of the 1st measuring roll 12A and the 2nd measuring roll 12B is formed by the poly-urethane rubber of excelling in abrasion resistance.Impact and bruit de froissement when the poly-urethane rubber mitigation contacts with compensates rope 7, and prevent rope is injured.In addition, because the 1st measuring roll 12A and the 2nd measuring roll 12B possess bearing, so alleviated contact resistance even 7 contacts of the compensates rope in moving on the 1st measuring roll 12A and the 2nd measuring roll 12B, are also rotated through the 1st measuring roll 12A and the 2nd measuring roll 12B.
In the 1st arm 13A, as shown in Figure 4, cardinal extremity is attached on the framework 11, and is as shown in Figure 5, and the rotation end is attached at from the axle 121 of the end extension of the 1st measuring roll 12A.Equally, as shown in Figure 4 in the 2nd arm 13B, cardinal extremity is attached on the framework 11, and is as shown in Figure 5, and the rotation end is attached at from the axle 121 of the end extension of the 2nd measuring roll 12B.The 1st arm 13A and the 2nd arm 13B make the 1st measuring roll 12A and the 2nd measuring roll 12B direction displacement to the row that cross compensates rope 7 respectively through being that rotate at the center with separately cardinal extremity.
As shown in Figure 5; At the interval S that the 1st measuring roll 12A and the 2nd measuring roll 12B do not touch scope and the 1st measuring roll 12A and the 2nd measuring roll 12B of compensates rope 7 is that bar 14 keeps the 1st arm 13A and the 2nd arm 13B in the scope below 2 times of diameter d of compensates rope 7.Cardinal extremity 141 that kind as shown in Figure 6 of bar 14 are attached on the 2nd arm 13B rotationally, and the front end 142 of bar 14 passes the 1st hole 131 of the lug 130 that is formed on the 1st arm 13A.And the distance that the nut midway 143 through being installed in bar 14 is set between the 1st measuring roll 12A and the 2nd measuring roll 12B is so that it is against on the lug 130 from the 2nd arm 13B side impact.
That is, if be made as the interval S between diameter d, the 1st measuring roll 12A and the 2nd measuring roll 12B of compensates rope 7, then setting at interval, S is d＜S＜2d.At this moment; Because the 1st measuring roll 12A and the 2nd measuring roll 12B dispose with respect to compensates rope 7 faces symmetrically, so the distance between the distance between the 1st measuring roll 12A and the compensates rope 7 and the 2nd measuring roll 12B and the compensates rope 7 is set at (S-d)/2 respectively.
It is as shown in Figure 6 to suppress spring 15, through break-through on the bar 14 of part in the 1st hole 131 of lug 130 of the 1st arm 13A, the direction of leaving to front end that makes bar 14 142 and lug 130, be about to the direction application of force of lug 130 pushing and pressing on nut 143.Thus, suppressing spring 15 inhibition the 1st measuring roll 12A and the 2nd measuring roll 12B leaves each other.If to the directive effect that the 1st measuring roll 12A and the 2nd measuring roll 12B are pushed open, then the 1st measuring roll 12A and the 2nd measuring roll 12B are to the direction displacement of leaving each other than the strong power of the constrained force that suppresses spring 15.
Like Fig. 4 and shown in Figure 6, in the 2nd hole 132 of the lug 130 on being formed on the 1st arm 13A, wear introducer 161 along the direction of the 1st arm 13A displacement.The cardinal extremity 162 of this introducer 161 is fixed on the carriage 160 that is installed on the framework 11.Neutral spring 16 is installed in respectively on the introducer 161 of the both sides that extend to lug 130.Neutral spring 16 is configured between carriage 160 and the lug 130 respectively with the mode that clips lug 130 and between the front end 163 of lug 130 and introducer 161.
Like this, neutral spring 16 is assembled between the 1st arm 13A and the framework 11, so the 1st measuring roll 12A and the 2nd measuring roll 12B are disposed with respect to the reference position of compensates rope 7 at a certain distance.Here, so-called " reference position " is meant when compensates rope 7 position that compensates rope 7 should not exist during runout.After, the 1st measuring roll 12A, the 2nd measuring roll 12B, the 1st arm 13A, the 2nd arm 13B, main rope 6 are being called under the situation of " reference position ", all refer under the situation that does not have to disturb their situation with the state configuration that should locate originally.
Like Fig. 6 and shown in Figure 7, cam 172 has camming surface 172A, is assembled on the 1st 175.Camming surface 172A contact is on the action piece 171A of switch 171.Is that action piece 171A displacement is rotated at the center through cam 172 with the 1st 175.This camming surface 172A possess 1st 172B of contact on the action piece 171A of outstanding state, with action piece 171A remain the 2nd 172C of the state of pushing and from the 1st 172B to the 2nd 172C bonded assembly displacement face 172D smoothly.
It is the concentric circles at center that the 2nd 172C forms with the 1st 175.Contacting under the situation on the action piece 171A with the 2nd 172C, cam 172 does not receive torque.Thereby if turn to the posture that contacts with action piece 171A in the scope cam 172 of the 2nd 172C, then cam 172 is maintained at this posture.In addition, displacement face 172D forms along the face of gradually opening (involute) curve.With respect to the angle of cam 172 rotations, the addendum modification of action piece 171A is certain.That is, owing in order to make torque that cam 172 rotations need for certain, so the action of cam 172 and action piece 171A is stable.
Under the situation of this embodiment, as shown in Figure 7, the distance from the 2nd 176 to connection shaft 177 is than from the 1st 175 distance to connection shaft 177.Thereby as shown in Figure 8, the angle that cam 172 is rotated is bigger than the angle that lever 173 is rotated.That is, only enlarge slightly, cam 172 is turned to enough make the angle of switch 171 actions through the distance between the 1st measuring roll 12A and the 2nd measuring roll 12B.
In addition, to shown in Figure 6, this intersection detecting device 10 possesses a pair of help roll 17C at the two ends of the row of compensates rope 7 like Fig. 4.Help roll 12C is configured to, and makes it with respect to the 1st measuring roll 12A and the 2nd measuring roll 12B grade separation.Help roll 12C suppresses compensates rope 7 along the 1st measuring roll 12A and the 2nd measuring roll 12B runout.Help roll 12C is contained on the pivot shaft 121C via bearing set, is fixed on the framework 11.The outer surface of help roll 12C and the 1st measuring roll 12A and the 2nd measuring roll 12B are same, are formed by parts, the for example polyurethane of excelling in abrasion resistance.
In above such elevator device 1 that constitutes, under the situation of many compensates rope 7 with the 1st pattern runout of messy motion, adjacent two intersections, as shown in Figure 9, the cross part 7A of rope is through intersecting detecting device 10.Thus, the interval S of the 1st measuring roll 12A and the 2nd measuring roll 12B is pushed away big maximum width 2d to cross part 7A.That is, interval S is set to the 1st measuring roll 12A and the 2nd measuring roll 12B displacement (2d-S)/2 respectively of the scope of d＜S＜2d.
As a result, the 1st arm 13A and the 2nd arm 13B that kind shown in figure 10 are rotated to the direction of leaving each other.Be indexed to relatively through the 1st arm 13A and the 2nd arm 13B more than the clearance G between the operating side 173B of the hook 174A that is set in striker 174 and lever 173, the hook 174A of striker 174 knocks the operating side 173B of lever 173.And, if lever 173 is rotated, then cam 172 rotations, action piece 171A is pushed in the main body of switch 171.Switch 171 is pushed into to be set to export through action piece 171A becomes disconnection.
With under the situation of consistent the 2nd pattern runout that moves of identical direction, compensates rope 7 contacts are on some measuring rolls in many compensates rope 7.At this moment, the 1st arm 13A and the 2nd arm 13B that kind shown in figure 12 link through bar 14.Thereby the interval S of the 1st measuring roll 12A and the 2nd measuring roll 12B is suppressed spring 15 and keeps.
Shown in figure 11, if compensates rope 7 is met on the 1st measuring roll 12A, then the 1st measuring roll 12A is pushed and displacement by compensates rope 7.And the 2nd measuring roll 12B is shown in figure 12, is keeping at interval S and to the direction displacement identical with the 1st measuring roll 12A.
Under the situation of compensates rope 7 with the 2nd pattern runout, the 1st arm 13A and the 2nd arm 13B to identical direction displacement to keep S at interval.Thereby the hook 174A of striker 174 is not in contact with on the operating side 173B of lever 173.That is, switch 171 does not break off.If compensates rope 7 is got back to the reference position,, make the 1st arm 13A and the 2nd arm 13B get back to original position then through being installed in the neutral spring 16 between the 1st arm 13A and the framework 11.Intersection detecting device 10 makes the 1st measuring roll 12A and the 2nd measuring roll 12B turn back to original position through the power of neutral spring 16.Thus, the runout of compensates rope 7 is suppressed.
Like this, intersection detecting device 10 suppresses the rope runouts.At this moment, under the situation that the adjacent rope of such imagination as shown in Figure 9 intersects, switch 171 is broken off, under the situation of identical direction displacement, switch 171 is maintained the state of unlatching at such rope shown in figure 11.Under situation because of the swing of building or wind rope swing, roughly be the 2nd pattern, like Figure 11 and shown in Figure 12, test section 17 is failure to actuate.
The elevator device 1 that as above, constitutes possesses control part 18.These control part 18 that kind as shown in Figure 1 are connected on the intersection detecting device 10, get involved in the control that makes car 4 runnings.In addition, this control part 18 is not independently, can be the parts of a part that constitute the control panel 202 of elevator device 1 yet.With reference to Figure 13 the function of this control part 18 is described.
Diagram of circuit shown in figure 13 is such; Car 4 begins to move (S1) if car call login or hall call login are arranged in the housekeeping runs of elevator device 1, and then control part 18 begins to be located at and intersects the supervision (S2) of signal of the switch 171 on the test section 17 of detecting device 10.Control part 18 judges whether that the signal of switch 171 becomes disconnection, promptly whether detects the intersection (S3) of rope.
Detecting under the situation of intersection, control part 18 is open circuited situation storage (S4) with switch 171, and unusual (S5) taken place in report to administrative center.Even control part 18 before arriving the bed of interest of executory running during in the signal of switch 171 become disconnection, car 4 is promptly stopped.Control part 18 moves to behind the nearest bed of interest of car 4 login car 4 operation is stopped.In addition, stop layer under the situation of hall login, also can make car 4 stop at this plan and stop layer in hall nearest on the direct of travel of car 4 plan of being used as.
Storing under the situation of detection signal, the passenger is being broadcasted the running of interrupting car 4, the service stopping (S8) of car 4.Arrive and affirmation situation and accomplish and resume operation (S9) before at worker, the service of car 4 is the state that stops., the signal of switch 171 reported the possibility (S5) that rope has intersection to administrative center in advance when becoming disconnection.Thereby, shortened the time that worker is reached the spot.In addition, also can arrive bed of interest, when making service stopping, report the unusual situation that taken place to the administrative center of this elevator device 1 at car 4.
If the maintenance of rope and recovery are accomplished, begun the service of car 4 again, then become standby (S10) state up to next call login.In addition, under the situation that does not store the signal under the situation that detects intersection, become standby (S10) state up to next calling takes place.
Like this, control part 18 car 4 move during in detect by test section 17 under the situation that the 1st measuring roll 12A and the 2nd measuring roll 12B leave, car 4 is stopped to the bed of interest of (corresponding to " at first " of Japanese) at first from car 4 logins.Elevator device 1 is if the degree that rope intersects then can only limit to this running, make car 4 move to bed of interest without a doubt.Thereby, as this elevator device 1, make car 4 stop, make the passenger more to feel at ease for the passenger from the railway carriage or compartment rapidly to bed of interest at first.
In addition, under the situation that main rope 6 and compensates rope 7 are compared, effect has the tension force of the amount of suspension craning cab 4 and bob-weight 5 on main rope 6, and with respect to this, compensates rope 7 only acts on the tension force about the weight that compensating rope sheave 71 is arranged.Thereby the intersection of rope takes place in compensates rope 7 more easily.Thereby, the detecting device 10 that intersects be arranged on for the intersection that detects compensates rope 7 compensating rope sheave 71 near.In addition, intersect detecting device 10 also be arranged on for the intersection that detects main rope 6 main rope sheave 31 and track adjusting wheel 32 near.
The switch 171 that is located on the test section 17 constitutes in the 1st embodiment, makes it under the situation that action piece 171A is urged, become disconnection.As long as output the 1st measuring roll 12A and the 2nd measuring roll 12B leave the above situation of 2d, test section 17 is that what kind of structure can.For example, test section 17 also can constitute, and is detecting the outstanding apart from action piece 171A under the condition of enlarged of the 1st measuring roll 12A and the 2nd measuring roll 12B, also can be the lever that action piece 171A changes with the two-position.
In addition, in the diagram of circuit of Figure 13, detected by test section 17 under the situation that the 1st measuring roll 12A and the 2nd measuring roll 12B leave, control part 18 also can action as following.For example, judge whether to have set bed of interest through the car call login, the situation of setting bed of interest at no one judges in car 4, not having the passenger.And the running of car 4 is stopped.In addition, setting bed of interest, be judged as under the situation that the passenger is arranged in car 4, the moving velocity of car 4 is being slowed down, up to making car 4 be accommodated to bed of interest at first.
According to the elevator device 1 that as above, constitutes, the cross part that on main rope 6 or compensates rope 7, produces is through through intersecting detecting device 10 and by early and detect reliably.Thereby, can be with the anti-possible trouble that terminates in of the fault of equipment.
The intersection detecting device 10 of the elevator device 1 of the 2nd embodiment is described with reference to Figure 14.Have with the structure of in the 1st embodiment, representing of each structure identical functions of detecting device 10 of intersecting and in Figure 14, give the identical label of structure with the elevator device 1 of the 1st embodiment.And,, omit the record here through record with reference to cooresponding the 1st embodiment.In addition, intersection detecting device 10 shown in Figure 14 and the 1st embodiment to intersect detecting device 10 same, all adopt detecting under the situation that compensates rope 7 intersects and detecting under the situation that main rope 6 intersects which.Intersect in order to detect compensates rope 7, the detecting device 10 that intersects be arranged on compensating rope sheave 71 near, intersect in order to detect main rope 6, the detecting device 10 that intersects be arranged on winch 3 main rope sheave 31 and track adjusting wheel 32 near.
In the intersection detecting device 10 of the 2nd embodiment, test section 17 not only is arranged on the single end of the 1st measuring roll 12A and the 2nd measuring roll 12B, also is arranged on two ends.Other structures and the 1st embodiment to intersect detecting device 10 identical.Thereby, about the explanation of detail portion and the explanation of control of elevator device 1 of intersection detecting device 10 that possesses the 2nd embodiment with reference to the record of the 1st embodiment.Shown in figure 14, under the more situation of the radical of main rope 6 or compensates rope 7, be that the 1st measuring roll 12A and the 2nd measuring roll 12B are elongated under 9 the situation in the 2nd embodiment.If it is one-sided that test section 17 only is located at, then be under the situation of intersecting apart from two ropes of test section 17 position farthest, the 1st measuring roll 12A and the 2nd measuring roll 12B might because of its cross part through oblique opening only.Under these circumstances, worry that intersection detecting device 10 might can not detect the situation that cross part passes through.
