Two, the horizontal detection and the mechanical type well straightening mechanism course of work:
With relay J
1, J
2The cable of constant open contact by cable drum, receive the worm-gear speed reducer motor control loop by the hook beam, so that J
1The adhesive motor just changes, and drives screw mandrel, pulley decline.Relay J
2Adhesive, the motor counter-rotating drives screw mandrel, pulley rises.Right low left when high when the hook beam, U type pipe right-hand member probe contacts relay J with the mercury face
1Adhesive, motor is just changeing the drive screw mandrel, pulley descends, this is equivalent to left end suspension centre (see figure 1) wire rope elongated, make hook beam left position descend (because the multiplying power of wire rope pulley group concerns, the decline of pulley slippage and hook beam left end has a proportionate relationship), till the right-hand member probe breaks away from the mercury face.
In like manner, when the right high left side of hook beam is low, relay J
2Adhesive, the motor counter-rotating, screw mandrel, pulley rise, and make hook beam left position concern rising in proportion, till the left end probe breaks away from the mercury face.Rely on so continuous adjustment can make the balance quality of hook beam reach the regulation requirement.
