The utility model also provides a kind of control method of multi-plate auto-folder stage, and this control method comprises the folding control method of folding stage and the stretching, extension control method of folding stage.Wherein, folding control method comprises the following steps:
1) control three lifting mechanisms 20 to raise, make often to organize between two pieces of stage boards 11 in stage there is certain angle (as shown in Figure 9), meanwhile, and control hoist engine 40 and do rope closing motion;
For ensureing fold sequence folding first group of stage, second group of stage successively, finally the 3rd group of stage, so needing to control corresponding lifting mechanism 20 lifting heights pass is h1>h2>h3, h1 is lifting mechanism 20 lifting heights on first group of stage, h2 is lifting mechanism 20 lifting heights on second group of stage, and h3 is lifting mechanism 20 lifting heights on the 3rd group of stage.
Cause folding stage entire length to shorten due to the rising of lifting mechanism 20 in this process, in the process in order to avoid looseness of steel wire ropes, hoist engine 40 be controlled and do rope closing motion.And folding stage overall length is changed to non-at the uniform velocity change, so hoist engine 40 rope closing speed also will regulate through its frequency modulator the effect reaching total tune.
2) at completing steps 1) after, control hoist engine 40 and at the uniform velocity first group of stage is folded up (as shown in Figure 10), and control lifting mechanism 20 retracted for clearance on first group of stage.
The power of providing support can not be continued, so lifting mechanism 20 retracted for clearance on first group of stage should be controlled simultaneously because lifting mechanism 20 in this process leaves ground.
3) first group of stage is folded into always after bottom it, two limiting brackets 18 contact, first group of stage cannot continue to fold again, along with at the uniform velocity pulling of hoist engine 40, pulling force is transmitted to second group of stage therefore starts folding second group of stage (as shown in figure 11), controls second group of stage boards 11 lifting mechanism 20 simultaneously and carries out retracted for clearance motion.Similarly again the 3rd group of stage boards 11 to be folded, finally complete stage and fold.
4), after stage folds completely, drive the overall transverse translation of stage to regulate its deposit position by push-pull device at fixed.
Stretching, extension control method comprises the following steps:
1) first stretch the 3rd group of stage, the electric pushrod mechanism 30 controlled on the 3rd group of stage works, and is pushed open (as shown in figure 12) by two pieces of stage boards 11, controls hoist engine 40 simultaneously and puts rope motion;
Because stage is stretched to the folding inverse process of stage, for ensureing that safety should need first to stretch the 3rd group of stage.In stretching, extension stage initial stage electric pushrod mechanism 30, two pieces of stage boards 11 are pushed open, angle between two pieces of stage boards 11 becomes large gradually, so foldable integral stage length, and foldable integral stage length is non-at the uniform velocity change so hoist engine 40 also should be regulated by its frequency converter put rope speed and coordinate to make mass motion.
2) at completing steps 1) after, angle in 3rd group of stage between two pieces of stage boards 11 becomes greatly, stage boards 11 self gravitation can be utilized and control hoist engine 40 and at the uniform velocity put rope by stage stretching, extension, control electric pushrod mechanism 30 retracted for clearance (as shown in figure 13) simultaneously.
In this process because electric pushrod mechanism 30 can not reoffer thrust, so need to control electric pushrod mechanism 30 retracted for clearance simultaneously.
3) control lifting mechanism 20 to extend and land, then coordinate control hoist engine 40 type discharge rope with the slow reduction of lifting mechanism 20, the 3rd group of stage boards 11 is stretched and paves; Successively second group, first group stage stretched similar with it is paved;
As shown in figure 13, when the 3rd group of stage is extended to certain position, because stage boards under this state 11 is too little with ground angle γ, so only enough pulling force cannot be provided with hoist engine 40 tension system, therefore its lifting mechanism 20 need be controlled extend and land.
4), after stage full extension, drive the overall transverse translation of stage to regulate its putting position by push-pull device at fixed.
The various embodiments described above are only for illustration of the utility model, the structure of each parts, size, setting position and shape all can change to some extent, the application of machine construction principle provided by the utility model and control method simultaneously is also not only confined to folding stage, on the basis of technical solutions of the utility model, all improvement of individual part being carried out according to the utility model principle and equivalents, to derive the identical fold mechanism of principle (as solar energy folded battery plate or some is large-scale, heavy folding apparatus) all should not get rid of outside protection domain of the present utility model.
