Description
Technical field
The present invention relates to a kind of drive system that is used for narrow actuating device space, it less having via the drive wheel of the double steel cable winding of a corresponding wheel and one at least 2: 1 steel cable of driving motor, a diameter that comprises a narrow structure is hung.
Background technology
Known have a drive wheel device that double steel cable twines, and wherein driving motor and drive wheel and corresponding the wheel are installed in the common actuating device space or in the space that separates together.The driving motor but also the back-geared motor that below not only do not have reducing gear all are understood that driving motor.
As the supporting structure between the bearing of the bearing of drive wheel and corresponding wheel, steel structure is a kind of possibility, and is for example described according to EP 0 100 072 A2.This supporting structure also can be a vertical shaft top board between drive wheel and corresponding wheel in very big actuating device, as for example described in DE24 41 992 A1.
When using very little actuating device space, when for example at least two walls that are equivalent to vertical shaft cross-sectional plane or vertical shaft when the actuating device space in right-angle view (birds-eye view) vertically extend in the actuating device space, have sizable space problem in the actuating device of the above-mentioned driving motor of quoting with traditional long structure, the scantling length of described driving motor is greater than its diameter.
A kind of actuating device of narrow make is provided in this respect, and its axial length is shorter than its diameter (US 5 018 603).Because its narrow make is by utilizing best in the counterweight of car back in car weight and counterweight together with the space between system's spacing of elevator.According to described US 5 018 603 drive wheels overlap joint driving motor member, so driving device becomes extremely flat.But this diameter by drive wheel is born.The diameter of drive wheel is greater than the diameter of driving motor.But because torque is proportional to square increase of the diameter of a drive wheel, this make requires very high-performance driving motor, especially described driving motor be decelerator-free and hang operation with 1: 1 of car.
Summary of the invention
The objective of the invention is to, a kind of durable drive system of being convenient to install that is used for narrow actuating device space is provided, the wherein also special simple inexpensive and good come-at-able installation of paying attention to actuating device and car.
Reach according to the feature of this purpose of the present invention by claim 1.Favourable further formation is illustrated in all dependent claims.
The driving motor of one narrow structure be incorporated into the less drive wheel of a diameter-always relatively the diameter of driving motor-and the correspondence wheel that a double steel cable that is used for drive wheel twines a kind of possibility is provided, promptly can realize the actuating device of a very little generally low energy consumption and the lighter load of steel cable.Special in big adjustable height and big rising or falling speed, the double steel cable of drive wheel twines and the power-handling capability of relative raising brings big advantage.Wherein can abandon other common the having " undercut " or the groove of " wedge shape section ", produce very favorable influence this service life steel cable and drive wheel itself for " semicircle " groove in the drive wheel.Cord drive with double winding can not have system's spacing of any requirement that is adapted between car and the counterweight difficultly in addition.
Because at least 2: 1 suspension of car and counterweight, remove and be provided with a correspondence that is used for the double winding of drive wheel takes turns, a kind of actuating device that is used for is possible in take up room the especially little make of internal segment save space ground setting of machine.Though in the groove of drive wheel, there is not the wedge shape section of undercut or groove when little drive wheel diameter, to reach high propulsive effort yet.Can be especially with respect to the driving motor diameter when the suspension of 2: 1,3: 1 or 4: 1, identical dead load be adopted thinner steel cable than the setting of the drive wheel of minor diameter.The application of thinner steel cable produces such influence to the axial length of drive wheel again, though thereby promptly want the groove of double number owing to double winding but still can keep the length of less drive wheel also to keep the small construction length of whole actuating device.The service life that when using 4 or more thin steel rope, also increases steel cable in addition like this, promptly when a steel cable has bigger elongation than other steel cable then other steel cable only must bear a relatively little component of total power together.Same service life of improving drive wheel, corresponding wheel and leading sheave, thereby because dead load is assigned on a plurality of steel cables and a plurality of grooves.
In other form of implementation of the present invention, terminal anchor fitting of needed steel cable and/or other leading sheave are arranged on together with actuating device on the common skeleton frame at least one 2: 1 of car hang.The common formation of actuating device (comprising the band retarder of narrow structure or driving motor, a connection box, a brake equipment and the drive wheel of decelerator-free), corresponding wheel, skeleton frame, connecting element and/or other leading sheave one system element.Skeleton frame itself is provided with each leg or special vibration damping holder.Therefore this system element of the present invention comprises the equipment of whole mechanical techniques except that steel cable.Just can realize installing by simple arrangement and not want any anchor fitting of skeleton frame in the actuating device space that be used for.This is possible, because in system element, need not the adjusting work that adds, thus all static(al) of horizontal forces and the almost nil and not displacement of generation systems unit on its installation surface of summation of power.
Therefore can be by simple especially mode installation system unit.Utilizing refitting together to put takes up room the system element machine of packing into interior and does not have other steady job.Mechanical framework does not stably tilt and is not bearing in movably on its preferred rubber tie plate.Only also need each end of the corresponding steel cable that pierces into is fixed on attachment point predetermined on the mechanical framework.This loads by application of rubber usually or spring-loaded pull bar (Zugstange) realizes that the steel cable earrings is in its each end, selectively guides steel cable via the additional leading sheave that is bearing in the skeleton frame in 3: 1 suspension.
Overall narrower make by system element, for elevator with the counterweight that is positioned at the car back, can utilize the space between system's spacing of car weight and counterweight best, wherein except that the installation of the reality of system element, can realize by-pass around machinery by code requirement.Do not have 3 sides and to guarantee such by-pass difficultly.Therefore need be for the actuating device space greater than the bottom surface of predesignating by lift well.
In a form of implementation of the present invention, counterweight and is guided between the sidewall of car and vertical shaft not between the rear wall of the rear wall of car and vertical shaft.The leading sheave half-twist of the leading sheave of car and counterweight correspondingly.If thus in vertical shaft and the car the door in both sides, then the import of both sides and where necessary a passage by car be possible.
In a form of implementation of the present invention, skeleton frame is divided into the partial sum that comprises actuating device and corresponding wheel comprises that steel cable is fixed and/or the part of other leading sheave in order better to transport.Under inconvenient execution conditions, be convenient to erection work whereby.
According to another modification of the present invention, thereby for static weight that improves permission and the total weight that improves complete elevator, actuating device is equipped with an outer support (Aussenlager) on the drive wheel next door.
Between connecting, each steel cable is used for elevator control device according to a favourable form of implementation in addition or/and the clearance envelope between each leading sheave at other can be used for installing control device of electric motor and chooses wantonly.Therefore control device of electric motor can become the parts of a system element and it is installed and installing at equipment side equally in of the present invention one further constitutes.
To car with favour perpendicular line to the direction of counterweight and extend, and make it on summation, not only produce vertical synthetic total power again in each steel cable section of another form of implementation of the present invention to car but also to counterweight.

In contrast to this, Fig. 4 schematically illustrates from the view of seeing car 8 and counterweight 14 from the top within unshowned hoistway wall same drive arrangement.Having of supporting there can be found out at the end face of car frame 9, and having of supporting there can be found out to the leading sheave 16 of counterweight 14 with the counterweight of the steel cable section 17,18 of leaving counterweight 14 at the end face of counterweight frame 15 to the leading sheave 10 of car 8 with the car of the steel cable section 11,12 of leaving car 8.The distance that in axial direction misplaces with the leading sheave 16 of the leading sheave 10 of X mark car and counterweight.The center of gravity and the layout of counterweight 14 in vertical shaft of unloaded car 8 depended in this dislocation.Almost extend vertically or respectively in the car 8 that car 8 and counterweight 14 hang in center of gravity or near its center of gravity and ran 11,12,17,18 is set up in the workshop and the system's spacing of counterweight 14 with the angle tilt ground of identical reverse side and obtain thus one vertical with joint efforts.Might not have any its fixing measure ground that is used for whereby and in the actuating device space, skeleton frame 1 is installed in vertical shaft top board 6.There is not or has only minimum moment loading in addition to the guide rail of unshowned car frame 9 and counterweight frame 15, the loss due to friction when therefore reducing operation simultaneously.
The drive wheel 3 that the double steel cable in this outer twines and the service direction of corresponding wheel also are provided with unlabelled dislocation among the figure of 1/2nd cable diameters.The car import is one-sided (in front).
Show system element of the present invention among Fig. 5 and Fig. 6 greatly simplifiedly, it is provided for the suspension of counterweight between a sidewall of sidewall of car and vertical shaft.Hoistway wall itself is not shown.Be apparent that the position of car 8 and car frame 9 is compared half-twist with Fig. 1 with Fig. 4, so that can enter car (Fig. 6 from the right with from the left side) from two opposed sides.This allows for example handling goods.Fig. 6 illustrates birds-eye view.If in both sides door is arranged in vertical shaft and car, a passage (otherwise among Fig. 6 from right to left or) is possible.Also consider such setting in building, it for example allows hierarchically that an alternately enters vertical shaft.
Correspondingly with respect to the leading sheave 10 of car 8 supporting cars and rotation/dislocation the leading sheave 16 and the counterweight 14 of counterweight be set.
Certainly car and counterweight also can hang mutually with the ratio of even number arbitrarily.
The steel cable section 12 of steel cable 5 is not to be fixed on the end connecting element of skeleton frame 1 in by 3: 1 suspension of the car of Fig. 7 and counterweight, but steel cable section 12 is at first via another leading sheave 21 guiding, this leading sheave is bearing on the skeleton frame 1, and just is fixed on after it turns on the end connecting element 13 on the car frame 9.Correspondingly, the steel cable section of counterweight leading sheave is at first equally extended and just is fixed on after it turns on the end connecting element on the counterweight frame 15 at the leading sheave of skeleton frame 1 upper support via one.Axis/the axle of the leading sheave 21 that each is additional is preferably placed on the straight line and each leading sheave 21 mutual spacing own is positioned at driving motor- drive wheel unit 2,3 and corresponding space of taking turns 4 back abreast.Between two leading sheaves 21 or equally its back or above still have enough spaces in order to control device of electric motor and/or elevator control device to be installed.Therefore the actuating device space for the accessibility of three sides with actuating device does not need to be compared to the bigger planar design of lift well itself.
Whole end connecting elements and the leading sheave of skeleton frame 1 upper support in the workshop system's spacing or the steel cable width between centers according to the design-calculated elevator set, therefore in 3: 1 suspension, also saved and be whole adjusting work of installation system unit.Also need not any other the installation of the skeleton frame of realizing complete outfit regularly 1 on vertical shaft top board 6 here.Steel cable makes a concerted effort vertically to act on, so skeleton frame 1 can laterally offset.
Also can realize 4: 1 suspension in a simple manner by Fig. 8 in addition.All be arranged on the skeleton frame 1 to the end connecting element 13 of the steel cable section 12 of escalator direction with to the attachment point 19 of the steel cable section of counterweight direction, conspicuous as this by Fig. 1 to 3.From the steel cable section 12 of the cage side of the end connecting element 13 on the skeleton frame 1 equally via first leading sheave, 10 guiding at car frame 9 upper supports on top.But in addition steel cable 5 turns to via a leading sheave 21 at skeleton frame 1 upper support as steel cable section 11 and before steel cable 5 twines overdrive wheel 3 and corresponding wheel 4 doublely, turns to via second leading sheave 10 at the car frame upper support on top once more.Realize the guiding of steel cable in an identical manner in the counterweight side.
Between two leading sheaves 21 on the skeleton frame 1 or its back or above still have enough spaces that is used for preferably installing control device of electric motor 20 and/or elevator control gear again in the workshop.Though guarantee according to code requirement at 3 by pass linees around machine, the actuating device space does not still need the bigger area that provides than vertical shaft cross-sectional plane.
For each end the end of skeleton frame 1 fix and at each leading sheave of skeleton frame 1, car frame 9 and counterweight frame upper support also in the workshop system's spacing or the steel cable width between centers according to the design-calculated elevator set, therefore in 4: 1 suspension, also saved and be whole adjusting work of installation system unit.The anchor fitting that also need not any other is here realized the installation of framework 1 on vertical shaft top board 6 of complete outfit.Whole steel cable power is according to synthetic vertically effect of steel cable guiding, so skeleton frame 1 can laterally offset.As in other the suspension situation, not having or insignificant little moment is applied on the guide rail of the guide rail of car frame 9 and counterweight frame and the friction force that produces will move the time reduces to minimum yet.
If but importantly the maximum torque of drive machines will be dropped to the load of weight mass or, then also might be the bigger transmitting ratio of car for counterweight selection ratio because the stroke that is used for counterweight that reduces will provide a clearance envelope at the vertical shaft top board.
In all embodiments, in order better to transport and better to install, system element can separate.Advantageously be divided into by skeleton frame 1 that the partial sum one that comprises actuating device 2,3 and corresponding wheel 4 comprises end connecting element 13,19 or/and the part of other leading sheave where necessary.Two parts of system element can be installed in abreast or in combination one by one by their each skeleton frame on the vertical shaft top board 6 and not have the fixing of any other.
Thereby for static weight that improves permission and the total mass that improves a complete set of elevator, actuating device 2,3 is equipped with a unshowned outer support on drive wheel 3 next doors in addition.
In addition according to particularly advantageous further being formed between the end connecting element 13,19 or/and the clearance envelope between other each leading sheave can be used for installing control device of electric motor 20 and the optional elevator control device that is used for.
The suspension of 3: 1 or 4: 1 can be used to have the layout of the counterweight of side guiding equally.
For hoisting depth from about 30m, surpass the running velocity and the dead load that reaches 3200kg of 2m/s, the size of cord drive can be determined as follows when one for example takes to hang car at 2: 1:
The diameter of-drive wheel, corresponding wheel and leading sheave: 320mm-500mm;
The diameter of-round steel rope: 8mm to 12mm;
The number of-round steel rope: 4 to 6.
