Outfan from sensor is connected with original apparatus for controlling elevator, and described motor 7 is revolved according to ladder cage by apparatus for controlling elevator
The signal control start and stop of rotaring signal and range sensor and direction.
In the first described fixture 1 and the second fixture 8, any one is arranged on rotation support body, and another is arranged on
On fixing bracket body.
Preferably, described limited block is provided with tourelle, contacts with tourelle in position time tool tentacle.It is described
Tourelle be the bearing for stretching out limited block and being connected with limited block, or the roller 3 being connected with limited block by bearing.
It is further preferred that being additionally provided with water proof and dust proof cover on the second fixture 8.
The anti-implementation for crossing rotation positioning device of above-mentioned intelligence, comprises the following steps：
Under S1, original state, mechanical tentacle 5 is for stretching out state, as shown in figure 3, rotation support body is relative with fixing bracket body quiet
Only；Under this state, mechanical tentacle 5 can be not necessarily contacted with limited block, might have the gap of very little.
S2, before rotation support body starts rotation, Motor drive moving parts cause mechanical tentacle to retract, as shown in Fig. 2
Rotation support body rotates again, it is to avoid propped up by mechanical tentacle during rotation.
S3, rotate support body rotation be near completion when, Motor drive moving parts cause mechanical tentacle to stretch out, after stretching out control
Spinning movement processed is completed, and returns to original state.The mechanical tentacle before rotation support body is rotated in place must be controlled first to stretch out, it is to avoid
Cross and turn.
In whole process, range sensor is cooperated with triggering block, for judging that mechanical tentacle is extended and retracted is
It is no in place；Touch sensor is used for judging whether limited block is contacted with mechanical tentacle, can be theory of mechanics or electrical principles
