Detailed description of the invention
Describe cooperation drawings and Examples in detail embodiments of the present invention below, by this to the present invention how application engineering means solve technical matters and the implementation procedure reaching technology effect can fully understand and implement according to this.
One embodiment of the balanced compensated catenary system of car of the present invention illustrates with reference to Fig. 2.Towing machine (not shown) is arranged in the machine room 200 on elevator 100 top.Main hawser 600 extends at the traction sheave 300 of towing machine with between the auxiliary sheave 400 of traction sheave 300 apart from one section of suitable length with canoe.By traction sheave 300 edge dangle and under main hawser 600 be connected to car 800 in this end with rope one to one, and by auxiliary sheave 400 edge dangle and under main hawser 600 be wound in pulley 120 (described pulley 120 with two to a rope suspensions variable weights 110) and one end of main hawser 600 be connected to the fixed part 90 of the centre being positioned at elevator 100.
The main hawser 600 and the secondary hawser 700 that hang car 800 are connected to each other with adaptor union 500.Moreover, suppose the bottom part 92 of car 800 at elevator 100, the length D of main hawser 600 is at least car 800 by the range ability of bottom part 92 to top layer part 94, and D is D1+D2, wherein D1 is length to auxiliary sheave 400 and D2 is by the length (as shown in Figure 2) of auxiliary sheave 400 to adaptor union 500 and the length of hawser 600 being wound around traction sheave 300 and auxiliary sheave 400.
When car 800 is at bottom, or when variable weights 110 is at upper, secondary hawser 700 has one can hang the length of pulley 120 at length D half height.The miles of relative movement of the adaptor union 500 moved between the standard of position between highest and lowest is equal to the half of the movable length D of main hawser 600.Secondly, when car 800 is in bottom part 92, in lower by explain the weight of boundary in car 800 limit and variable weights 110 edge weight between relation.Variable weights 110 be dangled by traction sheave 300 and auxiliary sheave 400 and under.
Traction sheave 300 dangles and weight on car limit is the weight (weight of car 800 of car 800 itself, its attachment device and annex thereof, and 50% take load), and length D and arrive traction sheave 300 length D1 main hawser 600 weight and.On the other hand, dangled by auxiliary sheave 400 and weight on variable weights 110 be following weight and, namely D/2 length adds by the weight of the secondary hawser 700 of the length S of adaptor union 500 to pulley 120, by the weight of the main hawser 600 of the length D2 of auxiliary sheave 400 to adaptor union 500, and the weight of pulley 120 and variable weights 110 and half.The weight of variable weights 110 side be by adjustment with approximately equal in the weight on car 800 limit.The adjustment of weight balancing can use large-sized rope or a large and heavy material to be completed as secondary hawser 700, maybe can adjust the weight of pulley 120 and variable weights 110.
On the other hand, when car 800 is in top layer part 94 and when becoming D1 in the length of the main hawser 600 of car 800 side, the weight of car 800 side be car 800 and to the main hawser 600 of the D1 length of traction sheave 300 weight and.In this case, the weight on variable weights 110 limit be pulley 120 and variable weights 110 weight and a half-sum D and D2 length main hawser 600 weight and.The weight of nearly all secondary rope by fixed part 90 support and do not act on auxiliary sheave 400.
Car damper element 130 and variable weights damper element 140 are typically provided in the opposite sense of car 800 and variable weights 110.Variable weights 110 is suspended in elevator 100 in the manner.Up damper element 131 on car 800 top ceiling be typically provided in on the downside of the floor of machine room 200 on stopper 132 relative edge to relax because car 800 is for the intense impact on the downside of the floor of machine room 200 caused by careless excessive operation.
No matter car 800 is at any floor, almost equal in the weight of variable weights 110 side at the suspended weights of car 800 side when running up and down.Moreover, when car 800 is in top layer part 94, the weight of the primary cable with length L is reduced at the suspended weights of car 800 side, it is sent to variable weights 110 side, and on the other hand, suspended weights in variable weights 110 side declines, and almost supported by the fixed part 90 in the weight of secondary hawser 700.Therefore, when car about 800 runs, also change at the suspended weights of variable weights 110 side.When car 800 is in top layer part 94 or bottom part 92, the suspended weights acting on towing machine is minimum and maximum weight and changing according to the thing followed.
Identical, in the embodiment shown in Figure 2, because main hawser 600 is connected to the secondary hawser 700 with the size being comparatively greater than primary cable by use adaptor union 500, adaptor union 500 is used as a weight.Therefore, in a such as skyscraper, when the midway location of adaptor union 500 on boundary between auxiliary sheave 400 and pulley 120, and when this skyscraper is subject to huge wind or earthquake and waves, most hawsers 600 also waves respectively.In the present invention, waving of this hawser 600 can be avoided by the adaptor union 500 of the structure had as shown in figs. 4 and 5.
That is, being connected with rod adaptor union 500 the top with secondary hawser 700 respectively bottom of main hawser 600.Most adaptor unions 500 is limited by common stopper 145 and moves in the horizontal direction.Common stopper 145 is fixed to adaptor union, and another adaptor union is the limited and vertical lax joint of level.The common stopper 145 extended along the line of adaptor union 500 limits the parallel motion of most adaptor union 500, and provides guide member 141 in its two ends.Guide member 141 catches installation in the channel in order to guide the guide rail 151 moved up and down.As mentioned above, hawser 610 can avoid the swing of waving of skyscraper and life.
In the above-described embodiment, 600 pairs, main hawser is wound between traction sheave 300 and auxiliary sheave 400 to make the angle of contact of main hawser 600 pairs of traction sheaves 300 larger.But when the angle of contact of main hawser 600 pairs of traction sheaves 300 does not need so large, it traction sheave 300 has been as shown in Figure 5 enough that main hawser 600 is singly wrapped in.
Except following, structure in figure 6 and effect are all with identical in fig. 2.
Variable weights 160 is suspended on the part of adaptor union 500 and is guided by guide rail, and guide rail can make hawser 610 avoid the waving of causing by the mass effect of adaptor union 500.In this instance, due to the associated weight of variable weights 160, the weight of pulley 120 and variable weights 110 needs to reduce.Moreover when variable weights 160 is suspended on adaptor union 500, compensated chain to need by the bottom hung of variable weights 160 to fixed part 90 in the channel to cause as the identical effect of secondary rope to adjust weight balancing.
In all the above embodiments, secondary hawser 700 is use adjust weight and fixed part 90 for hawser 710 is in the some of intermediate floor.Some on the intermediate floor of elevator must bear all wt and the tension force of secondary hawser 700, and therefore, elevator 100 must have the design of special power.
Therefore, as shown in Figure 7, most fixed part 90A-90D is distributed in most floors respectively, and the end of the secondary hawser 700 of majority is be connected to fixed part 90A-90D.Because this kind of mode reduces the burden of secondary hawser 700, design and the execution of elevator interlayer can be in a general way.Preferably, this fixed part 90A-90D point is else distributed to each intermediate floor.
Secondly other embodiment will be described, wherein using compensation chain 180 treats as secondary hawser 700 to perform the adjustment of continuous print weight.
With reference to figure 8, the hawser 610 being wound around traction sheave 300 in mode one to one hangs a car 800 in its one end, and hangs variable weights 170 in the other end.This variable weights 170 is by its bottom hung compensated chain 180.The length of compensated chain 180 is at least same as variable weights 170 goes up its foot part institute range ability most length from it, or chain arrives the length of well 112 in the channel.When variable weights 170 is in its extreme lower position, compensated chain storage tank 190 can hold nearly all compensated chain.
In above-mentioned structure, when car 800 is at bottom, the suspended weights of the hawser 610 of car 800 and D+D1 length almost with being equal in weight of the hawser 610 of the suspended weights of variable weights 170 and the total length of compensated chain 180 and D2 length.When car 800 is at top layer, the weight of the hawser 610 of the almost equal suspended weights in variable weights 170 of suspended weights of the hawser 610 of car 800 and D1 length and the length of D+D2 (comprising the length shifted by car 800).
In above-mentioned structure, when car 800 is run upwards by shown situation (car 800 is at bottom), shorten owing to being gradually transferred to variable weights 170 in the length of car limit hawser 610.Due to the transfer of hawser 610, compensated chain 180 continuous print is housed in compensated chain storage tank 190.When compensated chain 180 is contained in compensated chain storage tank 190, the weight acting on the compensated chain 180 of traction sheave 300 reduction gradually due to chain collecting.When car 800 finally arrives top layer, become at the suspended weights of cage side the weight of rope and the car 800 being equal to D1 length and.On the other hand, the suspended weights on variable weights limit be by the weight of the hawser 610 of the hawser 610 of the D length transmitted and the length of D2 and; It causes the balance of suspended weights.
Therefore, when car about 800 runs continuable execution weight adjustment, can not cause overbalance without the need to any known suspension cord.Its effect is same as aforesaid embodiment.
Except the embodiment shown by Fig. 8, variable weights 170 also can by the weight using quite thick chain to replace variable weights 170 as compensated chain 180.The compensated chain 180 that is modified to of this kind of situation needs makes U-shaped suspension, and its one end is fixed to the middle part of elevator hoistways.
With reference to figure 9, the hawser 610 being wound around traction sheave 300 hangs car 800 in its one end, and its other end hangs compensated chain storage tank 190 as variable weights, compensated chain 181 be hung by the downside layer of machine room 200 and under.The position relationship of boundary between car 800 and compensated chain storage tank 190 is: when both one at top layer, another is just at bottom.Compensated chain 181 is be suspended in the plane identical with compensated chain storage tank 190, and it has a length makes when compensated chain storage tank 190 is at bottom, and the end of compensated chain can not form burden to compensated chain storage tank 190.
In above-mentioned structure, when car 800 is upwards run by the situation shown (car 800 is at bottom), the rope of D length is transferred to variable weights 170 limit and shortening gradually, and the weight of hawser 610 by transfer, the weight on car 800 limit decreases.Due to the transfer of hawser 610, compensated chain storage tank 190 runs downwards and compensated chain 181 leaves compensated chain storage tank 190 gradually.By this, due to leaving of compensated chain, the weight of chain container reduces, and with the weight balancing on car limit.Therefore, the above embodiments also have the effect of previous embodiment.
In the embodiment shown by Figure 10, in order to adjust the compensated chain 182 of weight be by machine room 200 floor, downside hang and under, and with the variable weights 170 hung by hawser 610 at grade, variable weights 170 provide compensated chain retract cylinder 191 with the compensated chain 182 that reels.Compensated chain retracts cylinder 191 and driven by a motor 231.Motor 231 is controlled synchronous with the speed operated suffered by car (not shown) and direction to make.Moreover, when the minimum and maximum winding amount of compensated chain 182 occurs in variable weights 170 respectively at top layer or at bottom.
In above-mentioned structure, the weight of the winding amount of compensated chain 182 is be adjusted, therefore in suspended weights and the balanced being suspended on counterweight limit of cage side (not shown), when variable weights 170 is at top layer, and when compensated chain 182 is wound to its maximum.By this, when car (not shown) is upwards run, variable weights 170 moves down and unwinding compensated chain 182.By make the weight of unwinding compensated chain 182 be approximately equal to the hawser 610 arriving counterweight limit due to upwards running of car weight and leave car limit institute shorten the weight of rope with, even if when car runs up and down and makes the length of the hawser 610 on every limit change, also weight differential can not be produced between cage side and variable weights side.
