The invention provides a compact vibration absorption device for an elevator effectively dampening vertical vibration of low frequency and being stored in an outside dimension of a car frame. The elevator comprises a car frame 6 vertically moving in a hoistway 1; a car 5 provided in the car frame 6; a guide rail 2 for guiding the vertical movement of the car frame 6 and provided so as to be vertically extended; and a hanging rope 3 for supporting and lifting the car frame 6 through a pulley 4 below the car provided at a lower part of the car frame 6. A vertically moving dynamic damper 10 is provided below the car frame 6.
Description
Technical field
The present invention relates generally to a kind of shock-absorbing means of hoist cable formula elevator.
Background technology
Recently, the car framework that possesses lifting moving in hoist trunk, be arranged on the car in this car framework, guide the lifting moving of described car framework and extend the guide rail that is provided with along the vertical direction, and, support described car framework and make the elevator of the hoist cable of its lifting obtain using widely via the car lower sheave that is arranged on described car framework bottom.But the problem that exists is that generation is once vibrated, is the longitudinal vibration of low-frequency band (3Hz) near in this class elevator recently.
In order to address this problem, a kind of disclosed scheme is below the noose of suspension craning cab leaf spring to be set, and (for example the Japanese Patent spy opens clear 57-33181 communique (the 2nd page of bottom left hurdle the 6th walks to the 11st row, Fig. 4) about this leaf spring counterbalanced weight to be set.
In above-mentioned prior art, if distinctive oscillation frequency is adjusted to low frequency, will produces structure and increase and can't be contained in problem in the car frame body profile size.
Summary of the invention
The longitudinal vibration of low frequency that not only can decay effectively of the small-sized shock-absorbing means that the object of the present invention is to provide a kind of elevator to use, this shock-absorbing means, and can be contained in the oad of car framework.
To achieve these goals, elevator of the present invention possess lifting moving in hoist trunk the car framework, be arranged on the lifting moving of car in this car framework, the described car framework of guiding and extend the guide rail that is provided with along the vertical direction and via the car lower sheave that is arranged on described car framework bottom, support described car framework and make the hoist cable of its lifting, it is characterized in that: below described car framework, be provided with the dynamic shock-absorber that moves up and down.
As mentioned above, owing to below described car framework, be provided with dynamic shock-absorber moving up and down, by the effect of this dynamic shock-absorber, once Zhen Dong longitudinal vibration is absorbed effectively, and can be installed in the bottom of car framework because its structure is small and exquisite.

Fig. 1 is the front view of car frame body portion with elevator shock-absorbing means of one of embodiment of the invention.
Fig. 2 is the lateral plan of Fig. 1.
Fig. 3 is the enlarged drawing of the dynamic shock-absorber part of Fig. 2.
The specific embodiment
Followingly embodiments of the present invention are described with reference to accompanying drawing.
Fig. 1 is the front view of car frame body portion with elevator shock-absorbing means of one of embodiment of the invention.Fig. 2 is the lateral plan of Fig. 1.Fig. 3 is the enlarged drawing of the dynamic shock-absorber part of Fig. 2.
Among the figure, the 1st, the hoist trunk of high-rise, each guide rail 2 is vertically set on the two side of this hoist trunk 1, and between these two guide rails 2, lifting is provided with the car framework 6 and the car 5 that is arranged in this car framework 6 that is made its lifting by car lower sheave 4 by hoist cable 3 freely.In addition, each support 7 attached last lower corner (bottom is not shown) that are arranged on described car framework 6, each guide piece 8 is arranged in described each support 7, and it is configured to contact slip with the both sides and the end face thereof of described each guide rail 2.And each vibration-proof rubber piece 9 is laid on the bottom of described car framework 6 in the mode of supporting car 5.
And, between car lower sheave 4, being provided with dynamic shock-absorber 10, this dynamic shock-absorber 10 adopts the structure that down lifts from described car framework 6.Promptly, lifting plate 11a, 11b are fixed on the bottom of described car framework 6 by bolt of rear end plate 11c, 4 pilot bars 12 vertically down lift from lifting plate 11b, and the below of this pilot bar 12 is fixed on the link 4a of car lower sheave by adapter plate 4b, fixed clamp tool 4c and fastening nut 4d.Antirattle spring 13 is arranged on described each pilot bar 12 by spring support 13a, substrate 10a is installed on this antirattle spring 13, offer porose 12a on the substrate 10a, pilot bar 12 inserts among the 12a of this hole, on the upper and lower surface of this substrate 10a, counterbalanced weight 10b is installed via bolt of rear end plate 10c left and right symmetrically.In addition, this counterbalanced weight 10b adopts segmenting structure (sheet steel structure), and this structure makes that installation is more convenient, and can increase or reduce the piece number of counterbalanced weight easily.And the hole 12a of described substrate 10a and the slipper between the described pilot bar 12 have the collar 14 in order to reduce friction.
Described dynamic shock-absorber 10 has adopted said structure, and this is a kind of integrative-structure that down lifts from described car framework 6, and it is installed in the space between the car lower sheave 4.
Therefore, in described car framework 6, even the vibration during lifting etc. is delivered on the car 5 from car lower sheave 4 by hoist cable 3, also can be by described vibration-proof rubber piece 9 absorbing high-frequencies vibration, and by be installed in dynamic shock-absorber 10 decay on the described car framework 6 come from exterior, with the cooresponding low-frequency vibration of the distinctive oscillation frequency of car, thereby can suppress vertically to rock, make cage 5 become more comfortable.
Below, adopt formula to describe.
That is, in the dynamic shock-absorber 10 on being installed on described car framework 6, the elasticity modulus k of the spring 13 that shakes when setting up defences and the quality of counterbalanced weight 10b are m, and when peculiar oscillation frequency was f, following relational expression was set up:
f=1/(2π(k/m)
0.5)
Wherein, suppose when the exciting frequency that is delivered to car from described hoist cable 3 is f ' (it is equated substantially with the peculiar oscillation frequency of car), specify a value, make f '=f, so just can reduce to be delivered to the amplitude of the vibration of car 5 by described formula.
In addition, the weight of described counterbalanced weight 10b the best is a described car framework 6 and 10~20% of the total weight of car 5.That is, 10% effect when following reduces, 20% preponderance and bring obstruction to load capacity then when above.
Can obtain the effect of following excellence according to the present invention, promptly, owing to below the car of the car of the lifting rail of hoist trunk, be provided with the dynamic shock-absorber that moves up and down by hoist cable, so can suppress from exterior vibration and vertically rock, thereby make cage become more comfortable, simultaneously, owing to realized small and exquisite structure, so can be contained in the oad of car framework, thereby can be assembled in the existing car.
