22 move downward, and since the wirerope 23 of connection weight 22 is around the balance wheel 210 on swing rod 29, wirerope 23 gives swing rod 29 1
Downward tightening force, support spring 211 give 29 1 upward power of swing rod, make swing rod 29 in 22 motion process of weight and again
In the state that a balance is motionless when hammer 22 culminates.When weight 22 touches charge level, charge level to weight 22 1 to
On power, so that 22 moment of weight is formed weightless state, the power mutually balanced being subject to originally on swing rod 29 at this time is destroyed, weight
Hammer 22 is applied to the reduction of the power moment on swing rod 29, and swing rod 29 can be swung under the active force of support spring 211, swing rod 29
Second sensor is contacted during swing, when second sensor senses swing of the swing rod 29 because of 22 state of weightlessness of weight
Variation generates an electric signal, and for second sensor by the electric signal transmission to controller, controller receives electric signal control the
Two motor reversals drive weight 22 to rise back to the position on vertex.Primary detection is completed, the present embodiment can be supervised sensitively
The state of weightlessness of weight 22 is controlled, the second motor is timely controlled and weight 22 is driven to rise, avoid weight 22 and buried, lead to the
Two motors are impaired.
The wirerope that the present embodiment is used to hang weight successively bypasses directive wheel 25, balance wheel 210 and measures wheel 27, and by
In the position of directive wheel 25, balance wheel 210 and measurement wheel 27, make wirerope 23 in detour bending winding, in the normal test of weight 22
During rising, wirerope 23 is in tensioning state on directive wheel 5, balance wheel 210 and measurement wheel 27, keeps weight 22 stable
Raising and lowering.When the moment that weight 22 is weightless suddenly, 23 moment of wirerope between balance wheel 210 and measurement wheel 27 is in relaxation shape
State moves upwards balance wheel 210 and detects second sensor, at this point, quickly wirerope 23, wirerope 23 are tightened in reversion to reel 26
The movement of quick and stable under the active force of directive wheel 25 guarantees that weight 22 was capable of quick and stable rises into withdrawal shape
State, the application make weight 22 quick smoothly enter rising shape by state of weightlessness under the action of directive wheel 25 and balance wheel 210
State has reduced the shaking of weight 22 to the greatest extent, keeps the application movement steady, detection efficient is high.
It is further preferred that above-mentioned second sensor is Hall sensor, because Hall sensor is to magnetic-field-sensitive, knot
