The specific embodiment
Followingly embodiments of the invention are described with reference to accompanying drawing.
Fig. 1 is the section-drawing of the lift appliance among the present invention the 1st embodiment.As shown in Figure 1, in elevator lifting channel, vertically be provided with the guide rail 1 that a pair of section is the T word shape, lift car 43 is along this guide rail 1 lifting.At this, for the vibration propagation that prevents to cause because of the difference of height of guide rail 1 and bending etc. to lift car 43, between lift car 43 and elevator car frame 7, be provided with vibration-proof rubber spare 42.In addition, in the upper and lower of elevator car frame 7 guiding device 41a, 41b have been installed.The first rod member 3a, 3b, the 3c (not shown) that 3 guide roller 2a, 2b, 2c (not shown) have been installed on this guiding device 41a, 41b and respectively it have been carried out the axle supporting.In addition, coil spring 4a, 4b, the 4c (not shown) that from three directions guide roller 2a, 2b, 2c is pushed towards guide rail 2 by this first rod member 3a, 3b, 3c also has been installed.
About being installed in the guiding device 41a on elevator car frame 7 tops, below guide roller 2a, the 2b that the protuberance across T shape guide rail 1 is arranged on these protuberance both sides is elaborated with reference to Fig. 2.At first, be installed on the fixed way 8 and with the lower end of the first rod member 3a, the 3b of axle supporting guide roller 2a, 2b and support by pin.In addition, the lower end of the second rod member 9a, 9b is also supported and is installed on the fixed way 8 by pin.And, also being provided with the coil spring 4a, the 4b that are used to push the first rod member 3a, 3b, this coil spring 4a, 4b are set as compressive state in advance.The two ends of this coil spring 4a, 4b are installed in respectively on the first rod member 3a, 3b and the second rod member 9a, the 9b, and this coil spring 4a, 4b push guide roller 2a, 2b by the first rod member 3a, 3b towards guide rail 1.On the other hand, the upper end of the second rod member 9a, 9b interconnects by beam, whole formation connecting rod mechanism 31.
In addition, actuating device 33 is installed on guiding device supporting station 6.And this actuating device 33 is fixed on the connecting rod mechanism 31 by connecting base 35, has connecting rod mechanism 31 effect of top offset in the horizontal direction that makes.So, can make two second rod member 9a, 9b displacement by an actuating device 33, its result can control the elastic force that two coil springs 4a, 4b are produced.That is, can control the thrust pressure on the guide rail 1 of acting on of two guide roller 2a, 2b by a driver train.And, except actuating device 33 with straight reciprocating motion formula driver train, also can use driver train, for example use actuating devices such as the ball screw type driver train of pulse motor or cam-type driver train with other Spin Control forms.
Further since installed on the guiding device supporting station 6 be used to measure and guide rail 1 between the displacement pickup 32 of relative distance, whether occur tilting so can detect lift car 43.According to the measured observed reading of this displacement pickup 32, actuating device 33 makes connecting rod mechanism 31 along continuous straight runs displacements.
And, for the displacement with the first rod member 3a, 3b is controlled in certain scope, also be provided with killer 5a, 5b.Can avoid occurring between other equipment in the first rod member 3a, 3b and the hoist trunk collision thus.
Below the action of guiding device is described.Situation when at first bias load being acted on lift car 43 describes, that is, when situations such as the passenger enters lift car 43 in took place, bias appearred in the load-carrying meetings in the lift car 43, acts on lift car 43 thereby cause bias to be loaded.For example, thus the state when Fig. 3 represents that bias load acts on lift car 43 and makes lift car 43 tilt with respect to horizontal axis (X-axis line) that θ spends.At this moment, because the first rod member 3a, 3b tilt towards the right side, so the coil spring 4a on right side is compressive state, the coil spring 4b in left side is extended state.Like this, state shown in Figure 4 will occur, promptly the second rod member 9a, 9b tilt towards the right side.
, after measuring the inclination of lift car 43 by displacement pickup 32, actuating device 33 actions make the negative direction displacement of connecting rod mechanism 31 towards the X-axis line.Like this, the second rod member 9a, 9b are from bevelled state variation to the right to original state.Its result, the compressive state of right side coil spring 4a improves, and is increased by the thrust pressure that acts on guide rail 1 of the guide roller 2a of first rod member 3a axle supporting.On the other hand, the extended state of left side coil spring 4b improves, and is diminished by the thrust pressure that acts on guide rail 1 of the guide roller 2b of first rod member 3b axle supporting.Therefore, even the situation that bias load acts on lift car 43 occurs, because the thrust pressure that acts on guide rail 1 of guide roller 2a, 2b is under control, so the tilt phenomenon of lift car 43 can obtain correcting.
Because the above-mentioned action of guiding device, so, even reduce the elastic constant of coil spring 4a, 4b, also can suppress the influence of bias load.And, by connecting rod mechanism 31, can make two first rod member 3a, 3b displacement by an actuating device 33.That is, can control the thrust pressure that acts on guide rail 1 of two guide rollers by a driver train.
Below when just even lift car 43 is through the bending of guide rails 1 or difference of height part, the bias load situation that also can not act on lift car 43 describes.At this moment, by the vibration that coil spring 4a, 4b absorb the first rod member 3a, 3b, propagate to lift car 43 to suppress vibration.And connecting rod mechanism 31 in the horizontal direction can displacement.At this,, then can further reduce the amplitude of the vibration of propagating, thereby the travelling comfort of elevator is further enhanced to lift car 43 if set the elastic constant of coil spring 4a, 4b a little bit smaller.
In the present embodiment, the guiding device 41a that is arranged on lift car 43a top is illustrated, self-evident, be arranged on the guiding device 41b of lift car 43 bottoms and the middle guiding device that is used to guide other guide rails 1 that is arranged on opposite side across lift car 43 too.And in the present embodiment, the first rod member 3a, 3b and the second rod member 9a, 9b are installed on the fixed way 8, but also can adopt the structure that is directly installed on lift car 43 or the elevator car frame 7.And,, also can adopt coil spring 4a, 4b elastic body in addition as long as can apply thrust pressure to guide roller 2a, 2b.
Again, according to present embodiment, even set the elastic constant of coil spring 4a, 4b a little bit smaller, also can reduce the influence of bias load, so the vibration in the time of can reducing lift car 43 through the sweep of guide rails 1 or high lower part can improve the travelling comfort of lift appliance.And,, can also reduce the influence of the bias load that produces because of the center of gravity of the installation site of supply cable and lift car 43 is inconsistent etc. except reducing because of the passenger takes the bias load that causes.
And, because the thrust pressure that acts on guide rail 1 that two guide rollers 2a, 2b are produced is carried out interlock control, so when the bigger sweep by guide rail 1 part, the rapid phenomenon of rotation again after guide roller 2a, the 2b that a certain side also can not occur skids.For this reason, bias worn-down situation appears in the resin that can prevent guide roller 2a, 2b.
As mentioned above, present embodiment can provide a kind of guiding device, and this guiding device is because can be by the thrust pressure of a driving mechanisms control two guide roller 2a, 2b, so simple in structure, with low cost.
Fig. 5 is the details drawing of the guiding device in the lift appliance shown in the present invention the 2nd embodiment.In the present embodiment, will be used to promote that guide roller 2a, 2b are carried out an end of the fixed part of coil spring 4a, the 4b of rod member 10a, the 10b of supporting and be fixed on a platform 45, this platform 45 can move on guiding device supporting station 6.Movable platform 45 can make the straight line guiding piece 46 that is arranged between movable platform 45 and the guiding device supporting station 6 move on (directions X among the figure) in the horizontal direction by actuating device 33.In the 1st embodiment, because connecting rod is by rod member 10a, 10b and pin 31 supportings, so by the left and right displacement of guide roller 2a, 2b, small variation can appear in the height of connecting rod 31.For this reason, be necessary the connecting portion between actuating device 33 and the connecting rod 31 is arranged to and can be moved freely at above-below direction.According to this structure, because passing through coil spring 4a, 4b, movable platform 45 is connected, so actuating device 33 is combined fully with movable platform 45 with rod member 10a, 10b.For this reason, can realize the good and mechanism that can not occur becoming flexible of sensitivity, and can simplify driver train.According to this structure, can change the thrust pressure that acts on guide rail 1 of guide roller 2a, 2b easily.
Act on lift car and make the situation of lift car 43 towards left side if the bias load occurs, because rod member 10a, 10b tilt towards the right side, so the compressive state of coil spring 4a improves, the thrust pressure that acts on guide rail 1 of guide roller 2a increases.Measure the inclination of lift car 43 at displacement pickup 32 after, actuating device 33 actions make movable platform 45 (negative direction of X-axis line) displacement towards the left side.Thus, the thrust pressure of guide roller 2a obtains relaxing, and the inclination of lift car 43 is corrected, and the bias effects of load is minimized.
And when lift car 43 tilted towards the right side, actuating device 33 was towards the direction action opposite with above-mentioned situation, and the thrust pressure of guide roller 2b increases, so the inclination of lift car 43 is corrected.Therefore, in the present embodiment, equally also can provide a kind of guiding device, this guiding device is because can be by the thrust pressure of a driving mechanisms control two guide roller 2a, 2b, so simple in structure, with low cost.
