The continuous real-time angular value α for obtaining seat 1j；
If calculating angle value αiLess than or equal to first angle limit value α1, or calculate angle value αiIt is more than or equal to
Second angle limit value α2, then the position of the crane 4 is obtained again, persistently monitors the position of crane 4.Until calculating angle
Value αiCome back to first angle limit value α1With second angle limit value α2Between, then next step is carried out, so that seat 1 is followed
Crane 4.
Crane 4 has a specific working region range according to its actual need of work, when crane 4 is located at the work
When making in region, operator just needs specifically to operate crane 4, when crane 4 is not in the working region,
Operator only needs simply translation crane 4 or allows 4 automatic moving of crane to working region.First angle limit value α1
With second angle limit value α2It can need to be adjusted according to real work, by limiting the deflection angle of seat 1, can be improved
Automatically the efficiency rotated reduces the output investment of motor 22, saves electric energy.
Further, as shown in Fig. 2, crane 4 include laterally run along the first track 5 for being laid on overhead it is big
Vehicle 41 and the trolley 42 longitudinally running along the second track 6 being laid on cart 41.
When cart 41 runs to limit on the left position, and trolley 42 runs to rear extreme position, between crane 4 and seat 1
Angle be first angle limit value α1；
When cart 41 runs to limit on the right-right-hand limit position, and trolley 42 runs to rear extreme position, between crane 4 and seat 1
Angle be second angle limit value α2。
The rotation controlling party of automatic rotary seat in the utility model embodiment is illustrated below with reference to Fig. 4 and Fig. 5
Method.Fig. 4 is the initial position of seat 1, and Fig. 5 is the final position of seat 1.
Firstly, obtaining the position of trolley 42；Then, the angle between counting of carriers 42 and seat 1 obtains calculating angle value
αi1；α is judged againi1Greater than α1And it is less than α2, continue the real-time angular value α for obtaining seat 1j1, calculate αi1With αj1Difference；Finally,
Rotating mechanism 2 adjusts the deflection angle of seat 1 using PID control principle according to angle difference.The deflection angle of final seat 1
Certain amendment can also be carried out according to the left and right angular field of view of operator.In addition, control mechanism 3 can also be according to crane
The sample frequency of the angle signal of 4 position signal and seat 1 calculates the angulation change speed and seat 1 of crane 4
Angle value twice is acquired in rotation speed, such as 1s, the difference of angle is rotational speed values twice.Control mechanism 3 can be controlled
Motor 22 processed rotary seat 1 at the appropriate speed, follows the operation of trolley 42 always.Finally, trolley 42 is run to terminal, at this time
Judge αi2Greater than α2, rotary seat 1 is not continued to, the process that a rotation is adjusted terminates.
It can be seen from the above embodiments that, automatic rotary seat provided by the embodiment of the utility model, including seat, rotation
