Abstract
The utility model relates to a suspending object automatic eliminating swing device of an electronic control hoisting apparatus, which belongs to the technical field of automatic control. The utility model solves the technical problem that the movement of a suspending object is later than the movement of a crane; when the crane stops, the suspending object does not produce a swing under the action of inertial force or also does not produce a swing when is interfered by the ambient conditions. The utility model is characterized in that the device uses a tachogenerator which has the same axle with a moving trolley driving wheel to charge a capacitor; two groups of electric potential comparison circuits are matched, so after the moving trolley is controlled to a position, a the tachogenerator is driven to do positive rotation and reverse rotation. Accordingly, the hanging object can eliminate swing automatically. The utility model has the advantages of obvious efficiency, simple structure and safety. The utility model is suitable for the eliminating swing of the hanging object of the hoisting transport apparatus.
Description
The utility model belongs to the automatic control technology field.
In lifting and lifting industry, it hangs the motion that thing motion always lags behind hoisting crane, when hoisting crane stops, hanging thing and is subjected to the force of inertia effect will cause swing, or be subjected to the disturbance of fitful wind etc., also will cause the swing of hanging thing.Usually the pendular regime of taking that disappears is negatively to wait for the decay naturally of hanging the thing swing, or utilizes the artificial pendulum that disappears that disturbs.The pendulum if these methods of employing disappear will make work efficiency reduce, and also can make troubles with dangerous to production simultaneously.
The purpose of this utility model: for lifting and the lifting industry provide a kind of electron steering weight-lifting equipment to hang the automatic anti-swinging device of thing.This device utilize with the coaxial tachogenerator of the trolley drive wheel of following lift heavy thing to a charge of a capacitor, cooperate two groups of current potential comparator circuits, the controlled motion dolly puts in place afterwards and the just reverse of driving motor again, hangs the thing pendulum that disappears automatically thereby reach.What be applicable to handling machinery hangs the thing pendulum that disappears.
