Abstract
The invention discloses a kind of lift car self-balancing mechanism, including footstock and balancing chain；For the footstock between base and wheel disc, the center of the wheel disc is provided with hub, and axle sleeve is provided among the bottom of the base, and axle is mounted in the hub and axle sleeve, and the floor installation connected axle sleeve and be coiled on wheel disc in the both sides of axle, the balance.Simple in construction, low manufacture cost of the invention；Installation and simple to operate, good reliability, can be largely used to the transformation of old elevator, easy to spread；Elevator ride comfort is improved, reduces the friction of elevator guide shoe, improves the service life of elevator guide shoe.
Description
Technical field
The present invention relates to technical field of elevator equipment, specially a kind of lift car self-balancing mechanism.
Background technology
Elevator is arranged in high-rise building hoistway, and elevator guide shoe slides up and down (or rolling) if do not had along cage guide
Elevator wire rope balance system, car static balance (explanation is finished in elevator pit：Lift car static balance refers to, lift car
Under the suspention of traction steel-cable, remove four cars and lead boots, lift car does not tilt all around, in natural equilibrium shape
State.) after, elevator runs to each floor, leads what the stress on boots was just as, that is to say, that it is minimum (preferable to lead stress on boots
Zero) state stress is.The elevator of actual use, in order to balance the traction steel-cable change because of elevator operation, design configurations electricity
Terraced balancing chain.Because there is elevator balanced chain, when elevator rises, the pulling force of the balancing chain tie point under lift car is all changing,
The static balance for so resulting in lift car is changed into dynamic load imbalance, and as elevator runs to hoistway top layer, this dynamic load is uneven
Weighing apparatus reaches capacity, therefore caused additional load also reaches maximum.This additional load is passed on cage guide by car frame,
Make cage guide discontinuity, with regard to inevitable, the comfort level of such elevator operation is just affected for the vibrations of elevator operation；
For a long time, reciprocal load change, makes elevator guide shoe easily wear, lifetime.
Elevator operation will reduce vibrations, improve comfort, and only doing a car static balance in pit when elevator is installed is
It is far from being enough.Because the suspension centre of elevator balanced chain can not possibly be on the notional neutral face of lift car, that is, has 200-
300mm deviation.This is just the weight change of balancing chain, causes lift car additional load to leave hidden danger.In actual motion
Lift car, all it is unbalanced, and because floor improves greatly, this imbalance is increasing.Traditional elevator design ignores
Additional load caused by elevator balanced chain, ignore adding for the caused elevator guide shoe for shaking and thereby resulting in of this additional load
Huge abrasion.
The content of the invention
It is an object of the invention to provide a kind of lift car self-balancing mechanism, to solve what is proposed in above-mentioned background technology
Problem, possessed beneficial effect are：Elevator ride comfort is improved, improves the service life of elevator guide shoe.
To achieve the above object, the present invention provides following technical scheme：A kind of lift car self-balancing mechanism, including footstock
And balancing chain；For the footstock between base and wheel disc, the center of the wheel disc is provided with hub, among the bottom of the base
Provided with axle sleeve, axle is mounted in the hub and axle sleeve, the floor installation connected axle sleeve in the both sides of axle, the balance
It is coiled on wheel disc.
Preferably, the both ends of the axle are mounted on split pin.
Preferably, the axle sleeve is pvc pipe.
Compared with prior art, the beneficial effects of the invention are as follows：The device structure is simple, low manufacture cost；Installation and behaviour
Make simply, good reliability, the transformation of old elevator can be largely used to, it is easy to spread；Elevator ride comfort is improved, reduces electricity
Ladder leads the friction of boots, improves the service life of elevator guide shoe.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the left view of the present invention.
In figure：1- footstocks；2- bases；3- axles；4- split pins；5- axle sleeves；6- wheel discs；7- hubs；8- balancing chains.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Refer to Fig. 1-2, a kind of embodiment provided by the invention：A kind of lift car self-balancing mechanism, including the He of footstock 1
Balancing chain 8；For footstock 1 between base 2 and wheel disc 6, the center of wheel disc 6 is provided with hub 7, and axle is provided among the bottom of base 2
5 are covered, axle 3 is mounted in hub 7 and axle sleeve 5, base 2 is arranged on the both sides of axle 3, and balance even 8 is coiled in wheel disc by axle sleeve 5
On 6, the both ends of axle 3 are mounted on split pin 4, and axle sleeve 5 is pvc pipe.
Operation principle：Lift car will balance, and it is exactly to lead boots side to be reacted to four of lift car and lead on boots, front by
Power is uniform or is zero.Lead boots stress balance, then balancing chain torque both forward and reverse directions to caused by car are equal.The present invention uses
The both forward and reverse directions arm of force equal design, so in stress under the same conditions, positive and negative torque are equal, so as on boots are led
Without capability raw additional force.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit requires rather than described above limits, it is intended that all in the implication and scope of the equivalency of claim by falling
Change is included in the present invention.
