Description
Technical field
The present invention relates to elevator technology and manufacturing field, and in particular to a kind of car stabilizing mechanism.
Background technology
Generally using for elevator brings convenience to the life of people, at the same time, the comfort property of elevator also day
Benefit attracts attention.
Constantly improved now with building hoisting depth, the elevator of big hoisting depth also more and more applies to city
.Traction medium is relied on during lift car, is hung in hoistway, when hoisting depth is big, the elasticity increase of traction medium, car
Occur the sinking of short time with rocking in loading/unloading passenger.This brings bad boarding experience to passenger.To alleviate
This problem, elevator manufacturer often increase traction medium to improve system rigidity, but can bring significantly cost increase.
Therefore there is an urgent need to a kind of simple in construction, lower-cost stabilizing mechanism.
The content of the invention
The present invention is in view of the above-mentioned problems, propose a kind of stabilizing mechanism of lift car.Solve prior art and pass through increasing
Add traction medium to improve system rigidity, the problem of caused significantly cost increase.
The technical scheme that the present invention takes is as follows：
The stabilizing mechanism of the first lift car disclosed by the invention, the stabilizing mechanism of the lift car are used to be arranged on electricity
On terraced bridge railway carriage or compartment, coordinate with the guide rail of elevator, stabilizing mechanism includes：
Pedestal, for being relatively fixed with elevator cab, it is fixed with pedestal and is vertically directed device；
Carrier, it is slidably matched with the device that is vertically directed；
Close proximity electromagnetic iron, it is slidably mounted on the carrier；
Electromagnet is promoted, for driving close proximity electromagnetic iron to slide to guide rail；
Damper, one end are connected with the carrier, and the other end is connected with the pedestal.
For stabilizing mechanism improves system rigidity relative to increase traction medium, cost can be greatlyd save.
Except by increase traction medium improve system rigidity increase it is steady in addition to, have to enter by magnetic force in the prior art
The stable mechanism of row, its principle be after lift car stop, before door is opened, by electromagnetic attraction, guide rail and mechanism it
Between produce frictional force, prevent lift car from rocking；After elevator cab door closing, before lift car reruns, revocation electricity
Magnetic attraction, frictional force is eliminated, allows elevator normal operation.Prior art is carried out also by a pair of gear mesh guide rails of motor driven
Clamp.The common feature of both the above method is that mechanism provides a constant frictional resistance, and lift car is teetertottered
Prevented.Have a disadvantage in that, when constant frictional force is too small, stablizing effect unobvious, passenger still may feel that car
Strong sinking；When frictional force is excessive, frictional force can be revoked before lift car startup, lose the lift car of frictional force
Rock again, to reach new poised state.Secondly, in the life cycle of elevator, friction material can undergo up to a million times
Rub repeatedly, to ensure its life-span and stability, type selecting is extremely difficult；Or using conventional friction material, but need periodically more
Change.
The application slows down caused vertical wobble, stabilizing mechanism when elevator lift car load changes rapidly using damper
In use, by promoting electromagnet to drive close proximity electromagnetic iron to be bonded with guide rail, close proximity electromagnetic iron and guide rail are by magnetic attraction, surely
Its frictional resistance is determined during mechanism work from relative slip between close proximity electromagnetic iron and guide rail, but the liquid of damper
Pressure or air pressure resistance, when producing the obvious relative motion of speed between lift car and guide rail, carrier is relative with pedestal to be transported
Dynamic, close proximity electromagnetic iron is motionless, damper motion, while damper can provide larger reaction force, promote lift car quick
Calm down, and when car and during guide rail geo-stationary, damper does not provide resistance, so even if the release of close proximity electromagnetic iron not with
Guide rail magnetic attraction, obvious impact will not be also produced to lift car.
During practice, damper can use, but the damper for being not limited to following species comes：
1) two way damper, reduce and car rise and fall are rocked；
2) speed sensitivity damper, when speed of related movement is big, there is provided significant damping force, in speed of related movement
Hour, there is provided faint damping force；
3) adjustable damper, influenceed because temperature can be formed on speed-drag relationship of damper, can select can
The damper of mode, it is easy to building site according to present case to adjust.
Carrier is slidably matched with the device that is vertically directed being fixed on pedestal, using pedestal as object of reference, except can Yan Jing
Beyond road depth direction (y directions) translation, the carrier others free degree is limited.During practice, device is vertically directed
It can use, but be not limited in the following manner：

Also reversible close proximity electromagnetic iron can be selected, in dead electricity, electromagnet is carried to the absorption affinity for pressing close to object by permanent magnet
For when positive electric, permanent magnet is superimposed in the same direction with electromagnetic force, there is provided bigger absorption affinity, it is reverse must be electric when, permanent magnet
Reversely offset with electromagnetic force, there is no absorption affinity then externally.From reversible close proximity electromagnetic iron, can be obtained with low current bigger
Absorption affinity, release when, it is only necessary to repercussion be powered, you can eliminate absorption affinity.
Suitable frictional force is produced between close proximity electromagnetic iron and guide rail, on the one hand can tackle the car under common Loading conditions
Rock, on the other hand in car by damage, when drastically sinking in short-term, damping force exceedes maximum static friction force, and near
Sliding is produced between journey electromagnet and guide rail.To protect damper.

4) two flangings on carrier are used to limit the free degree of the close proximity electromagnetic iron in y directions, are set on electromagnet
The waist hole 25 of one transverse direction, a limit shaft 24 are fixed on carrier 4 through waist hole, to limit close proximity electromagnetic iron in z directions
The free degree, see Fig. 9.Equally, also upper bearing (metal) can be installed in limit shaft to reduce friction.
Had in cage guide angle in alignment error, can in order to allow close proximity electromagnetic iron to have, small deflection be free, it
Connected firmly completely with inter-agency not use of laterally steering, and be designed as a shaft hole matching for having gap
As shown in Figure 10, in the present embodiment, horizontal orientation device 5 includes the mounting groove being arranged on close proximity electromagnetic iron 8
26 and the cross spacing axle 27 (be equal with guide pillar 22 above) that coordinates with mounting groove 26, mounting groove 26 and cross spacing axle 27

As shown in Fig. 1,6~9, stabilizing mechanism also includes：
Horizontal back-moving spring 7, for resetting close proximity electromagnetic iron 8, away from the surface of guide rail 2；
Vertical back-moving spring 10, for resetting carrier 4.
Vertical back-moving spring is after carrier leaves initial position, there is provided reset force, its reset force are much smaller than close proximity electromagnetic
The frictional force of the offer of iron, when stabilizing mechanism discharges lift car will not be made to produce shake, and will not to the flat bed again of elevator
Generation is significantly affected, but remains to after stabilizing mechanism discharges, and carrier is slowly returned to back into initial position.
During practice, vertical back-moving spring includes following arrangement, but is not limited in the following manner
1) interacted using two springs, in home position infinite place device.
2) interacted using two springs, in home position limited location device.
3) roller is pushed to the V-block of a vertical direction using a compression spring.
Vertical back-moving spring needs to overcome the frictional force between the damping force of damper and piston and casing wall in effect,
Damping force meeting very little in low velocity, so frictional force can be more obvious.So be using the shortcoming of scheme 1, its home position
One section of section nearby is had, by thrust the conducting oneself with dignity plus carrier of two springs, three's vector is not enough to overcome damping
The frictional force of device, thus each time return when, carrier can not accurately return to home position, so device more easily reachs position
The limit is moved, is had an effect with spacer pin.Can solve this problem using scheme 2 or 3, carrier can be made to return original
Position, scheme 2 are compared with scheme 3, and the design space of scheme 2 is more compact.
Horizontal back-moving spring is used for when close proximity electromagnetic iron discharges, and short range electromagnet is moved into initial position, disengaging is led
Rail, horizontal back-moving spring can use but be not limited in the following manner：
1) it is connected on close proximity electromagnetic iron and the compression spring on carrier.
2 are connected on close proximity electromagnetic iron and the chip type spring on carrier.
3) it is connected on close proximity electromagnetic iron and the extension spring on carrier.
Due to needing to be arranged symmetrically to be the stress balance of upper and lower ends, close proximity electromagnetic iron translation is more beneficial for, can be with
Above scheme is arranged to transversely substantially symmetrical about its central axis two.
In the present embodiment, the side of close proximity electromagnetic iron 8 towards guide rail is fixed with friction plate (being not drawn into figure).Compared to iron
Relatively low stiction between iron, the frictional force between increasing and guide rail, preferably pasted using the friction plate of great friction coefficient
On the adsorption plane for investing close proximity electromagnetic iron.
In order to obtain stable support force on guide rail, guide rail, the spy of close proximity electromagnetic iron are adsorbed by activating close proximity electromagnetic iron
Point is, when pressing close to adsorbed target, very big absorption affinity can be produced with the electric current of very little.Equally it is to employ electromagnetic attraction to be
Normal pressure provides frictional force, and in this programme, electromagnet directly adsorbs in the side of guide rail, is produced in guide rail side and electromagnet
Raw magnetic confining field, friction plate are fixed on the surface of electromagnet, and guide rail is not required to additional friction piece again as armature on surface.
As shown in figure 4, in the present embodiment, damper 9 is separately positioned on the both sides of guide rail 2 with close proximity electromagnetic iron 8.So
Setting is to reduce the moment of torsion that vertical guider is subject to, and can be reduced as far as possible in close proximity electromagnetic iron working face and damper
The distance of the heart, it can now efficiently reduce moment of torsion torque arm length.
As shown in figure 5, the promotion electromagnet 6 of the present embodiment includes：
Cylinder 14, including a cavity 17, cavity 17 include join successively the first cylindrical sidewalls 16, transition side wall 18 with
And second cylindrical sidewalls 19, wherein, the internal diameter of the first cylindrical sidewalls 16 is more than the internal diameter of the second cylindrical sidewalls 19；
Piston rod 15, it is slidably arranged in cavity 17, piston rod 15 includes the large-diameter portion coordinated with the first cylindrical sidewalls
20 and the minor diameter part 21 that coordinates with the second cylindrical sidewalls, minor diameter part, which is used to passing cylinder and close proximity electromagnetic iron, to be coordinated.
In the cavity for promoting electromagnet, the cavity of closing is by narrow gap and extraneous UNICOM, when electromagnet ejects
When, the resistance that the air in cavity is formed can effectively reduce the speed of electromagnet ejection, realize slowly fitting, can effectively subtract
The absorption noise of few close proximity electromagnetic iron.
, as buffering, slow down the absorption of close proximity electromagnetic iron using with the extraneous cavity of minim gap UNICOM and press close to guide rail when institute
Caused noise；During practice, the structure can also be combined into one with horizontal orientation device.
As shown in figures 2-3, stopping means is provided between the carrier and pedestal of the present embodiment, stopping means includes setting
The bar shaped spacing hole 11 being vertically arranged on pedestal, and limited location pin 12 on carrier 4 is fixed on, spacer pin stretches into bar shaped
In spacing hole.By setting stopping means, can avoid because elevator fails in flat bed, the vertical displacement amount of carrier exceedes damping
The situation of device extreme position occurs.
When the present embodiment uses, excited in the case where car door is opened by the signal that apparatus for controlling elevator provides, and
Restored at closing time in cars.Due to the elevator lifted greatly, rocking for car is become apparent in lowrise layer, and control system also may be used
Excitation signal is selectively provided, the ability excitation apparatus such as only when resting in lowrise layer
Control system also such as can start again the mistake of flat bed using more targetedly mode come the start and stop of control device
Release device in journey, to reach higher flat bed progress, when elevator prepares to run next time, first release device, then read electricity
Terraced internal load weight, to obtain more accurately weight information.
During damping force demand when a systems stabilisation can not meet that lift car rocks, multiple stable dresses can be set
Put collaborative work.Control system can selectively trigger wherein any one or more devices, to obtain appropriate damping force.
The stabilizing mechanism of the present embodiment also can be used for cargo lift, and when reducing heavily loaded dolly disengaging car, car is slow
Rock, without away from flat bed region.Now need using the bigger damper of the close proximity electromagnetic iron and active force of bigger suction.
Its principle is identical with above-mentioned principle.
The present embodiment stabilizing mechanism one of which operation principle：
1st, during elevator is run, close proximity electromagnetic iron with the presence of horizontal back-moving spring, in home position,
Certain gap is kept with guide rail, avoids friction from producing.
2nd, out of service in elevator, before passenger passes in and out car, device obtains the signal for coming from control system, promotes electricity
Magnet obtains electric, pushes short range electromagnet to guide pass, and close proximity electromagnetic iron obtains electric, its own is adsorbed on guide rail, its absorption affinity
Both are made to keep geo-stationary enough.
3rd, lift car loads, in uninstall process, under common delivery operating mode (i.e. passenger normally passes in and out lift car)
One end of damper is connected on guide rail using close proximity electromagnetic iron, under in general loading/Unloading Condition, frictional force is sufficiently large
To making, close proximity electromagnetic iron is static to be attached on guide rail；When car load changes, car can the movement of upward/lower direction, now
Connection carrier also has relative velocity between the piston and cylinder body of the damper of pedestal, if lift car subsidence velocity increases
When, resistance caused by the hydraulic coupling between piston and cylinder body will also increase, and resistance is enough between lift car and guide rail
Speed control is in relatively low scope；
4th, when car sinks or is increased beyond flat bed section, but still in the setting range of stabilizing mechanism maximum displacement
(this value is more than flat bed section again).Elevator traction chance carries out lift car when small rotation comes and comes back to flat bed position
Put, now stabilizing mechanism is in running order, and because speed of related movement is relatively low, the damping force that damper provides is smaller, will not
The process of flat bed again is formed with langding accuracy to be influenceed.Note：Big hoisting depth elevator can all set story-leveling function again, that is, open the door
After lift car exceeds flat bed scope under state, elevator traction machine will carry out fine position, lift car is reentered flat bed
Region.
If the 5, elevator fails in flat bed, beyond device setting value, the spacer pin on carrier will slide it for car displacement
The chute end of pedestal, spacer pin will prevent carrier from being continued to move on pedestal, and force between close proximity electromagnetic iron and guide rail
Relative sliding is produced, with protection device itself.
6th, lift car loads, in uninstall process, when lift car (such as is had heavier small by the load impacting of exception
Car promotes lift car) and when exceeding the speed limit, reaction force caused by hydraulic damper exceedes rubbing of being provided of close proximity electromagnetic iron
Power is wiped, sliding is produced between close proximity electromagnetic iron and guide rail, to protect hydraulic damper not damaged by excessive pressure.
7th, after lift car completes loading/unloading, it will start and run next time, now lift car reaches one and put down
Weighing apparatus state, so now elevator car speed is substantially zeroed, hydraulic damper externally exports without power, so when nearly device discharges
Afterwards, close proximity electromagnetic iron departs from guide rail in the presence of back-moving spring, and completion this time acts.
8th, in running process of elevator next time, vertical back-moving spring less can push dynamic carrier, be allowed to slow
Slow is returned to initial position, is prepared for action next time.
For the stabilizing mechanism of the present embodiment improves system rigidity relative to increase traction medium, it can greatly save into
This.
Except by increase traction medium improve system rigidity increase it is steady in addition to, have to enter by magnetic force in the prior art
The stable mechanism of row, its principle be after lift car stop, before door is opened, by electromagnetic attraction, guide rail and mechanism it
Between produce frictional force, prevent lift car from rocking；After elevator cab door closing, before lift car reruns, revocation electricity
Magnetic attraction, frictional force is eliminated, allows elevator normal operation.Prior art is carried out also by a pair of gear mesh guide rails of motor driven
Clamp.The common feature of both the above method is that mechanism provides a constant frictional resistance, and lift car is teetertottered
Prevented.Have a disadvantage in that, when constant frictional force is too small, stablizing effect unobvious, passenger still may feel that car
Strong sinking；When frictional force is excessive, frictional force can be revoked before lift car startup, lose the lift car of frictional force
Rock again, to reach new poised state.Secondly, in the life cycle of elevator, friction material can undergo up to a million times
Rub repeatedly, to ensure its life-span and stability, type selecting is extremely difficult；Or using conventional friction material, but need periodically more
Change.
The application slows down caused vertical wobble, stabilizing mechanism when elevator lift car load changes rapidly using damper
In use, by promoting electromagnet to drive close proximity electromagnetic iron to be bonded with guide rail, close proximity electromagnetic iron and guide rail are by magnetic attraction, surely
Its frictional resistance is determined during mechanism work from relative slip between close proximity electromagnetic iron and guide rail, but the liquid of damper
Pressure or air pressure resistance, when producing the obvious relative motion of speed between lift car and guide rail, carrier is relative with pedestal to be transported
Dynamic, close proximity electromagnetic iron is motionless, damper motion, while damper can provide larger reaction force, promote lift car quick
Calm down, and when car and during guide rail geo-stationary, damper does not provide resistance, so even if the release of close proximity electromagnetic iron not with
Guide rail magnetic attraction, obvious impact will not be also produced to lift car.
