Hollow shaft motor rotates forward, and moves downward the utility model along pull rod, until pressure sensor is contacted with the spring seat of honour.Work as pressure
When the pressure value that sensor measures is equal to the 10% of initial set value, control device stops each hollow shaft according to control logic relationship
Motor work, then unscrews locking nut from the indentation, there of pressing sleeve using nut rotating tool (such as spanner) and tightens nut, make
Nut to be tightened to be kept completely separate with the spring seat of honour, the pressure that compression spring is born at this time just all acts on pressure sensor,
The pressure value that each pressure sensor is exported is the tensile force of each elevator wire rope.Control device is according to the initial pressure of setting
Value is compared and judges with the value that each pressure sensor measures, if initial setup pressure value is greater than what pressure sensor measured
Value, then control device drive hollow shaft motor compression pressure spring, until the two deviation within the range of permission when, hollow shaft
Motor stops working, and then tightens locking nut 32 and tightens nut 33, compression spring 35 is locked in current compressive state,
Finally, hollow shaft motor reversion makes the utility model integrally exit pull rod, the adjusting of steel wire tensioning power is completed.If initial setting
Pressure value is less than the value that the pressure sensor measures, then control device driving hollow shaft motor subtracts the decrement of compression spring
It is few, until the two deviation within the range of permission when, hollow shaft motor stops working, and then tightens locking nut 32 and tightens
Compression spring 35 is locked in current compressive state by nut 33, finally, hollow shaft motor reversion moves back the utility model integrally
Pull rod out completes the adjusting of steel wire tensioning power.
In the present embodiment, every elevator wire rope tensile force can also be carried out respectively using a utility model
Detection and adjusting.
