Fig. 5 describes the structure of emergency braking apparatus involved in the present invention 2.Mainly the structure different from the common emergency braking apparatus 2 shown in Fig. 2 described below.
It should be noted that, also between brake component guiding device 6 and brake component guiding device supporting member 8, be provided with B group roller 12.
In addition, emergency braking apparatus comprises: link gear 10, it comprises linkage piece 10a and linkage piece 10b, one end of this linkage piece 10a is being combined with the upper surface of brake component guiding device 6 at hand of rotation and the free-moving mode of horizontal direction, the other end is being combined with the lower surface of top framework 3 at hand of rotation and the free-moving mode of horizontal direction, be combined with the substantial middle of linkage piece 10a in the mode that can rotate freely in one end of this linkage piece 10b, the other end is combined with the lower surface of top framework 3 in the mode that can rotate freely; Extension spring member 13, be combined with the binding site with top framework 3 of linkage piece 10a in its one end, the other end and 5 combinations of side framework, and be endowed incipient extension power; Stopper element 14, it is combined with the lower surface of top framework 3, and is configured in the position with linkage piece 10a butt.In the present invention, the Length Ratio of the first linkage piece 10a and the second linkage piece 10b is constituted as 2: 1.
Below the action of emergency braking apparatus of the present invention is described.
State when Fig. 5 represents to move at ordinary times.
; due to by stopper element 14, bear produce press brake component guiding device 6 by the initial spring force of the extension spring member 13 of exerting oneself; so when brake component 7 is positioned at not the position with guide rail 1 butt, brake component 7 and brake component guiding device supporting member 8 do not bear the power of opening producing by exerting oneself by brake component guiding device 6.
Therefore, when normal operation, brake component 7 not with guide rail 1 butt.
At this, by before elastic body 9 distortion and guide rail 1 between distance be set as δ 0.
State when Fig. 6 represents that brake component 7 is raised and makes elastic body 9 reach maximum distortion.
When lift car 17 hypervelocity decline being detected, brake component 7 is raised mechanism and mentions, and embed between guide rail 1 and brake component guiding device 6, in addition, when brake component 7 is raised along the A group roller 11 of being located at guide rail 1 side of brake component guiding device 6, the effect of utilizing the dip plane of brake component 7 and brake component guiding device 6, brake component guiding device 6 moves towards horizontal direction.
Now, along with elastic body 9 opens, brake component 7 is pressed against guide rail 1, can to lift car 17 of the present invention, carry out emergency braking by friction force thus.
Under this state, by the incipient extension power of the extension spring member 13 of emergency braking apparatus 2 of the present invention, produced to brake component guiding device 6 by exerting oneself, be adjusted to elastic body 9 maximum distortion time the force balance that brake component guiding device 6 is pushed upward, so guide rail 1 changes to δ 1 from δ 0 with the position relationship of elastic body 9, but link gear 10 is indeformable.
In addition, as the equilibrium of forces in horizontal direction, the antagonistic force that the spring force being produced by the distortion of elastic body 9 and brake component 7 bear from guide rail 1 keeps balance.
State when Fig. 7 represents that brake component guiding device 6 is lifted towards top along A group roller 11 and B group roller 12.
It should be noted that, after brake component guiding device 6 is lifted, link gear 10 closures.
Consequently, represent that guide rail 1 and the δ of the position relationship of elastic body 9 diminish as δ 2 from δ 1.
This means that the variation that is lifted the width of the brake component guiding device 6 producing because of brake component guiding device 6 is dwindled the distortion of elastic body 9.
Fig. 8 a represents the relation linking between angle and the spring force of extension spring member 13.Fig. 8 c represent to link the spring force F1 of angle [alpha] and extension spring member 13 and 10 pairs of brake component guiding devices 6 of link gear by the relation of exerting oneself between F2.
In Fig. 8 a, transverse axis represents the angle [alpha] that links, and the spring force F1 that the spring force of the extension spring member 13 when the longitudinal axis represents each interlock angle [alpha] be take under initial condition (being 45 ° in the present embodiment) carries out the value that normalization obtains.
Along with link gear 10 closures, the top framework 3 that one end of extension spring member 13 is fixed and the binding site of the first linkage piece 10a are away from the binding site of the second linkage piece 10b and top framework 3, so the spring force F1 of extension spring member 13 increases.
Fig. 8 b represent to link angle [alpha] and 10 pairs of brake component guiding devices 6 of link gear by the relation of exerting oneself between F2.Transverse axis represents the angle [alpha] that links, and the longitudinal axis represents take and carry out the value that normalization obtains by exerting oneself under initial condition (being 45 ° in the present embodiment) by the F2 that exerts oneself the brake component guiding device 6 of each interlock during angle [alpha].
As mentioned above, characteristic as the link gear 10 shown in the present embodiment, along with interlock angle [alpha] diminishes, the amount of tension of the spring that the spring force F1 of extension spring member 13 causes corresponding to the distortion because of link gear becomes large, and along with interlock angle [alpha] diminishes, the diminishing gradually by the F2 that exerts oneself of brake component guiding device 6.
Below effect of the present invention is described.
Fig. 9 a represents the schematic diagram of the obtainable speed characteristic of the present invention.The speed characteristic when dotted line of Fig. 9 a represents to adopt common emergency braking apparatus, can know from figure, adopt when of the present invention, and velocity variations when elevator is about to stop slows down.That is, can suppress to be a significant slowdown, thereby can reduce the burden that the health to passenger brings.
Fig. 9 b means the schematic diagram of friction coefficient characteristic.From Fig. 9 b, can know, it is the same with common characteristic, and when elevator is about to stop, friction coefficient becomes large.That is, the frictional behavior of emergency braking apparatus 2 of the present invention also has very strong speed interdependence.
Fig. 9 c is the schematic diagram of guide rail pressing force characteristic.Guide rail pressing force characteristic when the dotted line in Fig. 9 c represents to adopt common emergency braking apparatus 2.
When adopting common emergency braking apparatus 2, guide rail pressing force becomes steady state value after brake component 7 and brake component stopper element 19 butts, and when adopting emergency braking apparatus 2 of the present invention, before brake component guiding device 6 is lifted, guide rail pressing force increases along with elastomeric distortion.
Along with brake component 7 is further mentioned, become large by exerting oneself than 10 pairs of brake component guiding devices 6 of link gear of the upper thrust that upwards pushes brake component guiding device 6, now, the width dimensions of brake component guiding device 6 changes because brake component guiding device 6 is lifted, the distortion of elastic body 9 is dwindled, and guide rail pressing force diminishes gradually.
Therefore, because the braking force of emergency braking apparatus 2 of the present invention equals the product of the guide rail pressing force shown in the friction coefficient shown in Fig. 8 b and Fig. 8 c, so braking force can not increase severely when elevator is about to stop.Therefore, as shown in Figure 8 a, the velocity variations that emergency braking apparatus 2 of the present invention can relax elevator when emergency braking while being about to stop.
Show in the present embodiment the structure while adopting extension spring member 13, but as shown in figure 10, also can adopt the Compress Spring member 14 that has been endowed initial compression force.
Figure 11 is illustrated in the embodiment that top framework 3 is set up the structure of brake component guiding device stopper element 16, and the object of this structure is to prevent that brake component guiding device 6 from exceedingly upwards being lifted, and suppresses thus braking force and disappears when elevator is about to stop.
After brake component guiding device stopper element 16 and brake component guiding device 6 butts, the distortion of elastic body 9 can further not diminish from this time point, so braking force can not disappear completely when elevator is about to stop.
