Specific embodiment
As shown in Figure 1, being a kind of rotation of rotary table electric limiting device of the embodiment of the present invention, the maximum rotation of turntable 100
Angle is limited in from initial position: rotate clockwise 180 °~360 °, rotate counterclockwise 180 °~360 °, rotate clockwise with
Rotating counterclockwise the stroke more than 180 ° is overlap-add region, and the stroke other than overlap-add region is non-superimposed region.
Due to turntable 100 cannot 360 ° of continuous rotations, started turning from initial position, turn left turn right can be more than 180 °
Then stop in some angle position, in this way turn left turn right just has partial stack region, if cannot tell turntable 100 be from
Which side enters overlap-add region, cannot limit the rotation of turntable 100 in the position of the limitation left/right rotation.
The improvement of the present embodiment is: rotation of rotary table electric limiting device includes angle of revolution detection device 200, revolution side
To detection device 300 and controller 400；The angle of revolution detection device 200 is used to detect the rotation angle of turntable 100 and anti-
It feeds the controller 400；The gyratory directions detection device 300 is used to detect the direction of rotation of turntable 100 and feeds back to institute
State controller 400；The controller 400 implements electric limiting to turntable 100 according to the rotation angle in non-superimposed region,
Overlap-add region implements electric limiting to turntable 100 according to the rotation angle and direction of rotation.
Any position point that may determine that in revolution stroke is combined with gyratory directions using angle of revolution, to implement
The electric limiting of any position point, needs to be arranged multiple position switch compared to conventional limit switch box and is just able to achieve multiple spot and electrically limit
Position, the technical program need to only install angle of revolution detection device 200,300 both parts of gyratory directions detection device, install,
Debugging, maintenance are all very convenient, and signal input point is few, the position that need to be controlled can according to need it is customized, do not need it is additional again plus
Input point, while implementation cost is lower.
As the specific embodiment of above-described embodiment, the angle of revolution detection device 200 be can choose using revolution
Encoder or angle of revolution sensor or other known angle detection devices, it is therefore intended that the rotation angle of detection turntable 100
Degree.Controller 400 is rotated clockwise and is rotated counterclockwise by different solenoid valve control turntables 100, such as left-hand rotation solenoid valve
500 controls rotate clockwise, and right-hand rotation solenoid valve 600 controls turntable 100 and rotates counterclockwise.
In the installation of specific component, the turntable 100 is fixedly installed on swing mechanism 700 and and swing mechanism
700 rotate synchronously, and the angle of revolution detection device 200 is installed on the speed reducer that driving swing mechanism 700 rotates, and examine in real time
The angle that survey time rotation mechanism 700 rotates.
Another embodiment of the technical program, on the basis of the above embodiments, such as Fig. 2, gyratory directions detection device 300
Including non-automatic recoverable switch 310 and collision block 320, the non-automatic recoverable switch 310 is installed on 100 outside of turntable downwards
On the mounting plate of extension, the collision block 320 is installed on non-automatic recoverable switch 310 in non-superimposed region and follows 100 turns of turntable
Changed on track when dynamic with the state for triggering non-automatic recoverable switch 310.
Non-automatic recoverable switch 310 is used to judge turntable 100 is which direction to enter overlap-add region from this embodiment
, collision block 320 must be mounted in the position other than overlap-add region, and can trigger the non-automatic change of recoverable switch 310 state, it is non-oneself
After moving the recoverable triggering of switch 310 change state, which is always maintained at, and just changes state again until triggering next time, thus
Accurately judge turntable 100 is which direction to enter overlap-add region from.And rotary encoder is not only used for overlap-add region, non-superimposed
Region any angular position can do electric limiting as needed, only unrelated with the state of non-automatic recoverable switch 310.
The technical program further includes embodiment of the method, a kind of controlling party using the rotation of rotary table electric limiting device
Method, the control method include the following steps (1) acquisition revolution operator input signal；(2) judge turntable 100 whether in superposition area
Domain；(3) if in overlap-add region, electric limiting is implemented to turntable 100 according to rotation angle and direction of rotation；(4) if not folded
Add region, then electric limiting is implemented to turntable 100 according to rotation angle.
Preferably, the turntable detected in the step (2) according to angle of revolution detection device 200 rotates angle to judge to turn
Whether platform 100 is in overlap-add region.The electric limiting implemented in the step (3) and (4) includes that turntable is allowed to revolve clockwise
Dynamic, permission turntable rotates counterclockwise, limits turntable turn clockwise, limitation turntable rotates counterclockwise.
Specific method implementation is as shown in figure 3, set overlap-add region as X1 °~X0 °, non-automatic recoverable switch
310 collision block 320 is installed on any position between 0 ° of position and X1 ° of position；It is defeated that controller 400 receives the operation turned left clockwise
Enter signal, when non-automatic recoverable switch 310 turns left clockwise with turntable 100, non-automatic recoverable switch 310 is touched
Change state after to collision block 320 and keep, turn left after entering overlap-add region, limitation left-hand rotation angle is no more than X0 °；It is returned when non-automatic
Return formula switch 310 with turntable 100 counterclockwise right-hand rotation when, non-automatic recoverable switch 310 changes again after touching collision block 320
Change state returns to reset condition and keeps, and when being turned back to 0 ° of position and continuing turning anticlockwise and enter overlap-add region, limits right turn angle
Degree is no more than X1 °.The revolution limitation in non-superimposed region directly passes through without the concern for the state of non-automatic recoverable switch 310
Rotary encoder (angle of revolution detection sensor) can carry out necessary limit.It is above a specific application example, touches
320 position of block may be mounted at any position of not 0 deg position other than overlap-add region, and it is from which that it, which is served only for identification turntable 100,
Direction enters revolution overlap-add region.
As shown in figure 4, the rotation of rotary table electric limiting device for the technical program applies the implementation in engineering machine vehicle
, partial view A is the rotation of rotary table electric limiting device of Fig. 2 in figure.
The above description is only a preferred embodiment of the present invention, and the present invention is not limited to above embodiment, as long as with
Essentially identical means realize that the technical solution of the object of the invention belongs within protection scope of the present invention.
