Figure 18 is the instruction diagram of the guide device for elevator movement of the present invention the 9th embodiment.Figure 18 (a) is a partial side view; Figure 18 (b) is its attached view.

The formation of mobile guiding device A5 is, roughly with the length direction arranged perpendicular of guide rail 4.The electromagnet A51 of mobile guiding device A5 installs coil A51a on magnetic body A51b, shown in Figure 18 (b), and the whole figure-three that forms in the cross section of this magnetic body A51b.

And, the gap detector A6 of the space g that detects magnetic body A51b and guide rail 4 is set in the end of the magnetic body A51b of electromagnet A51.Shown in Figure 18 (b), gap detector A6 is set at guide rail 4 respectively on 3 faces taking advantage of case 1 to give prominence to, shown in Figure 18 (a), is arranged on a pair of 2 gap detector A6a, A6b up and down that the lifting direction keeps certain intervals on each face.Dispose 6 gap detector 6 in other words altogether.Then, with anchor clamps A52 this electromagnet A51 is fixed on and takes advantage of on the case 1.

And, be provided with the space g control controller A8 within the specific limits that uses gap detector A6 to detect, utilize the magnetic force of adjusting loop A 51a generation to make space g keep certain.Controller A8 is usually according to any detection signal among 2 gap detector A6a, the A6b, the magnetic force of control electromagnet A51, space g is maintained fixed, when one detection signal steep variation, converts to from the detection signal of another gap detector A6 and control.

In other words, in the 9th embodiment, owing to be to keep certain intervals configuration a pair of gap detector A6a, A6b up and down in the lifting direction, so one of a pair of gap detector A6a, A6b up and down, for example, gap detector A6a detects under the situation of step-like distortion of seam of guide rail 4 etc., and another gap detector A6b does not detect step-like distortion.So, in the control of space g, do not use the seam detecting signal of guide rail 4.

Figure 19 is the characteristic map that is illustrated in from the control signal that uses in the detection signal of the gap detector A6 of the 9th embodiment and the space control.Figure 19 (a) expression comes the detection signal of the gap detector A6a of comfortable electromagnet A51 top setting; Figure 19 (b) expression comes the detection signal of the detector A6b of comfortable electromagnet A51 bottom setting; And Figure 19 (c) is illustrated in the control control signal of the space g of the magnetic substance A51b that uses electromagnet A51 and guide rail 4.

Promptly, in the control of the space g of electromagnet A51 and guide rail 4, use is from the signal of the gap detector A6a that is arranged on electromagnet A51 top, when taking advantage of case 1 to rise, near the step-like distortion of the seam of mobile guiding device A5 by guide rail 4 etc., then shown in Figure 19 (a), from the signal steep variation of the gap detector A6a that is arranged on electromagnet A51 top.At this moment, shown in Figure 19 (b), the gap detector A6b that is arranged on electromagnet A51 bottom does not detect the step-like distortion of guide rail 4.

So when from the signal steep variation of the gap detector A6a that is arranged on electromagnet A51 top, the signal that uses is converted to signal from the gap detector A6b that is arranged on electromagnet A51 bottom in the control of the space g of electromagnet A51 and guide rail 4.Its result, shown in Figure 19 (c), the signal that uses in the control in the space of electromagnet A51 and guide rail 4 does not have steep variation.

Thereby, can be smoothly and stably take advantage of the guiding support of case 1 as elevator.And, thereafter, when the gap detector A6b that is arranged on electromagnet A51 bottom detects the step-like distortion of seam etc. of guide rail 4, in the control of the space of electromagnet A51 and guide rail 4, the same signal that uses from the gap detector A6a that is arranged on electromagnet A51 top.

In the above description,, to the situation of taking advantage of case 1 decline too, can do the control of the space g of electromagnet A51 and guide rail 4 although the situation of taking advantage of case 1 to rise is described, can be smoothly and stably take advantage of the guiding support of case 1 as elevator.

The present invention the 10th embodiment then is described.Figure 20 is the instruction diagram of the guide device for elevator movement of the present invention the 10th embodiment.The 10th embodiment is different with the 9th embodiment shown in Figure 180, and 3 gap detector A6a, A6b, A6c are set, and controller A8 is according to 3 gap detector A6a, A6b, A6c detection signal central value, and the magnetic force of control electromagnet A51 makes space g certain.

In Figure 20, mobile guiding device A5 is configured to the length direction approximate vertical with guide rail 4.The formation of the electromagnet A51 of mobile guiding device A5 is at magnetic body A51b coil A51a to be installed, and shown in Figure 20 (b), the cross section is whole this magnetic body A51b that forms of figure-three.

And, in the magnetic body A51b end of electromagnet A51, the gap detector A6 of the space g that detects magnetic body A51b and guide rail 4 is set.Shown in Figure 20 (b), gap detector A6 is separately positioned on guide rail 4 on 3 faces taking advantage of case 1 to give prominence to, shown in Figure 20 (a), keeps certain intervals in upper and lower settings 3 gap detector A6a, A6b, A6c in the lifting direction on each face.In other words, dispose 9 gap detector A6 altogether.Then this electromagnet A51 with anchor clamps A52 fixedly on the premultiplication case 1.

And, the controller A8 that the space g that uses gap detector A6 to detect remains unchanged is set, make gap g constant by adjusting the magnetic force that loop A 51a produces.Controller A8 is according to the central value in 3 gap detector A6a, A6b, the A6c detection signal, and the magnetic force of control electromagnet A51 remains unchanged space g.

In other words, in the 10th embodiment, owing to keep certain intervals ground at guide rail 43 gap detector device A6a of configuration, A6b, A6c on each face of 3 faces taking advantage of case 1 to give prominence in the lifting direction, so when 3 gap detector A6a, A6b, A6c one for example gap detector A6a detected the step-like distortion of seam etc. of guide rail 4, other gap detector A6b, A6c did not detect step-like distortion.And owing to select the central value of these 3 detection signals to do the control of space g, so the detection signal of the seam of guide rail 4 does not use in the control of space g.

Figure 21 be expression from the detection signal of the gap detector A6 of the 10th embodiment and in the control of space the characteristic map of employed control signal.Figure 21 (a) is the detection signal from the gap detector A6a that is configured in electromagnet A51 top; Figure 21 (b) is the detection signal from the gap detector A6b that is configured in electromagnet A51 pars intermedia; Figure 21 (c) is the detection signal from the gap detector A6c that is configured in electromagnet A51 bottom.And, Figure 21 (d) be illustrated in space g to the magnetic body A51b of electromagnet A51 and guide rail 4 control in employed control signal.

In the 10th embodiment, controller A8 is in the control of the space of electromagnet A51 and guide rail 4, use from guide rail 4 to take advantage of 3 outstanding faces of case 1 each on respectively in the detection signal of gap detector A6a, A6b, the A6c of configuration, its value is the detection signal of central value.That is, when taking advantage of case 1 to rise, in case, near the step-like distortion of the seam of mobile guiding device A5 by guide rail 4 etc., so, shown in Figure 21 (a), from the detection signal generation steep variation of the gap detector A6a that is arranged on electromagnet A51 top.At this moment, shown in Figure 21 (b) and 21 (c), the gap detector A6c that is arranged on the gap detector A6b of electromagnet A51 pars intermedia and is arranged on electromagnet A51 bottom does not detect the step-like distortion of guide rail 4.

In this case, the central value detection signal from the detection signal of gap detector A6a, A6b, A6c becomes the signal that does not detect guide rail 4 seams.Therefore, employed detection signal becomes the no detection signal jumpy of its value in the control of the space of electromagnet A51 and guide rail 4.In other words, the signal from the gap detector A6a that is arranged at the no electromagnet A51 jumpy of its value top does not use in the control of the space of electromagnet A51 and guide rail 4.Thereby shown in Figure 21 (d), the signal that uses in the space of electromagnet A51 and guide rail 4 control does not have steep variation, can be smoothly and stably do the elevator guiding and support.

And, after this, the gap detector A6b that is arranged on the gap detector A6b of electromagnet A51 pars intermedia and is arranged on electromagnet A51 bottom is under the step-like distortion situation of the seam that detects guide rail 4 etc., too, employed signal does not have steep variation yet in the control of the space of electromagnet A51 and guide rail 4, can be smoothly and stably carry out the elevator guiding and support.

More than, though the situation of taking advantage of case to rise is illustrated, too, can do the space control of electromagnet A51 and guide rail 4 when taking advantage of case 1 to descend, carry out the guiding support that elevator is taken advantage of case 1 smoothly and stably.

Then, the present invention the 10th embodiment is described.Figure 22 is expression from the characteristic map of the detection signal of the gap detector 6 of the present invention the 10th embodiment and the control signal that uses in the control in space.The 10th embodiment is different with the 9th embodiment shown in Figure 20,21, replace the central value in the detection signal of 3 gap detector A6a, A6b, A6c, magnetic force according to the detection signal aviation value controller A8 of 3 gap detector A6a, A6b, A6c control electromagnet A51 makes space g certain.

In Figure 22, Figure 22 (a) expression is from the detection signal of the gap detector A6a that is arranged on electromagnet A51 top; Figure 22 (b) expression is from the detection signal of the gap detector A6b that is arranged on electromagnet A51 pars intermedia; Figure 22 (c) expression is from the detection signal of the gap detector A6c that is arranged on electromagnet A51 bottom.And Figure 22 (d) is illustrated in employed control signal in the space control of electromagnet A51 and guide rail 4.

In the 11st embodiment, the same with the 10th embodiment, on each face of taking advantage of 3 outstanding faces of case 1 of relative guide rail 4, set 3 gap detector A6a, A6b, A6c in the lifting direction with keeping certain intervals, in the control of the space of electromagnet A51 and guide rail 4, use signal from the detection signal aviation value of 3 gap detector A6a, A6b, A6c.

Taking advantage of under the case 1 rising situation, when near the step-like distortion of the seam of mobile guiding device A5 by guide rail 4 etc., shown in Figure 22 (a), the gap detector A6a that at first is arranged on electromagnet A51 top detects the step-like distortion of seam of guide rail 4 etc., on the other hand, shown in Figure 22 (b), 22 (c), not monitor station scalariform distortion of other gap detector A6b, A6c, employed signal is owing to being their aviation value, so level and smooth resembling shown in Figure 22 (d) in the space control of electromagnet A51 and guide rail 4.So doing the elevator guiding smoothly and stably supports.

And, after this, detect as the gap detector A6b that is arranged on electromagnet A51 pars intermedia and the gap detector A6c that is arranged on electromagnet A51 bottom under the step-like distortion situation of seam etc. of guide rail 4, too, employed signal does not have steep variation in the control of the space of electromagnet A51 and guide rail 4, can be smoothly and stably do the elevator guiding and support.

In the above description, though showed the situation of taking advantage of case 1 to rise, the situation when descending can be done the space control of electromagnet A51 and guide rail 4 too, can take advantage of the case guiding to support as elevator smoothly and stably.
