The utility model crane hanger balance system is arranged three rope end positions between trolley and equalizer bar and is balancing
Coplanar not conllinear drawstring encoder on beam, since three rope ends of three drawstring encoders constitute a plane, Ke Yitong
Cross compare three rope end positions that drawstring encoder detects moving displacement determine three rope ends constitute plane (i.e. equalizer bar
Plane) skew whether occurs, it further may determine that which orientation skew occurs for equalizer bar；
Further, the rope end of three drawstring encoders forms equilateral triangle centered on the center of equalizer bar, theoretical
Skew, only when torsion has occurred in the vertical direction of raising direction, three occur not in raising direction for equalizer bar of being taken in
The displacement of a rope end should be equal, then being all not equal to when the rope end that three drawstring encoders detect is displaced equal
When being displaced according to the theory that the electric machine frequency of lifting mechanism calculates, that is, it can determine whether that equalizer bar is sent out in the vertical direction of raising direction
Torsion has been given birth to, can prompt to need to be adjusted the degree of balance of suspender.
The utility model crane hanger balance system, structure is simple, can be realized to the multiple orientation of suspender skew and
Torsion is detected, and can be good at controlling the degree of balance of suspender using the utility model crane hanger balance system.
