Abstract

The invention discloses a wide and thick plate rolling mill main transmission shaft balancing device with fault monitoring and protecting functions. The wide and thick plate rolling mill main transmission shaft balancing device with the fault monitoring and protecting functions comprises position sensors, driving hydraulic cylinders, driving hydraulic cylinder bases, balancing device bottom plates, swinging support fixing bases, swinging supports and vertical connecting rod supports. When the angle position of a main transmission shaft is fixed and the main transmission shaft does not vertically swing or only swings in a small angle, in the process that the main transmission shaft rotates, if the obvious variable quantity of a sensor position value of the driving hydraulic cylinder occurs,it is indicated that main transmission shaft assemblies have faults, therefore, real-time fault monitoring of the main transmission shaft assemblies is achieved, and alarming or stopping interlockingcan be set according to difference of the detection value variable quantity of the position sensor under the condition.

Description

technical field [0001] The invention belongs to the technical field of equipment in the iron and steel industry, and in particular relates to a balance device for a main drive shaft of a wide and thick plate rolling mill with functions of fault monitoring and protection, which is used to balance the self-weight of the main drive shaft of a wide and thick plate rolling mill while realizing real-time on-line monitoring and alarming of main drive shaft component failures And automatic control interlock protection. Background technique [0002] Because of the large torque required by the rolls of wide and thick plate mills, the size and weight of the main drive shaft are relatively large. In order to reduce the influence of the self-weight of the main drive shaft of the rolling mill on the rotation of the rolls and the main drive shaft itself, the wide and thick plate mills are designed with a main drive shaft. Balance device to balance the self-weight of the main drive shaft. ...
