An escalator is a transport means for transporting pedestrians in a conveyor belt manner. The escalator driving device comprises a motor, a speed reducer, a main driving shaft, shaft tubes, driving sprockets, step sprockets, bearing seats and the like, wherein two ends of the main driving shaft are respectively fixed on the two bearing seats, the bearing seats are further arranged on a truss of the escalator, the shaft tubes are sleeved outside the main driving shaft, bearing devices are arranged between the shaft tubes and the main driving shaft, the shaft tubes can rotate around the main driving shaft, shaft tube flanges are integrally formed at two axial ends of the shaft tubes, the two step sprockets are respectively fixed with the two shaft tube flanges, and the driving sprocket is fixedly arranged with one step sprocket.
When the motor and the speed reducer work, power is transmitted to the driving sprocket through the chain, the driving sprocket is connected with the step sprocket to rotate, the step sprocket is fixed with the shaft tube, and the step sprocket drives parts such as steps to move through the step chain while rotating around the main driving shaft. The main drive shaft plays an important role in the escalator drive, wherein the magnitude of the static friction of the tensioning sleeve of the main drive shaft directly influences the performance of the main drive shaft. If the brake is not premounted after the brake is assembled on the main driving shaft, the surface fit of the friction plate of the additional brake and the surface of the brake disc is difficult to be completely matched, and the friction plate is difficult to eliminate when the elevator is used in the later period, so that the later operation fluctuation of the elevator is large and unstable.
Disclosure of Invention

The aim of the invention is achieved by the following technical scheme:
the utility model provides an automatic staircase main drive additional brake premiller, is including placing main drive's fixed frame and carrying out the rotation actuating mechanism of premiller to additional brake disc, rotation actuating mechanism and fixed frame swing joint, rotation actuating mechanism includes the mounting bracket, sets up at the power pack of mounting bracket rear portion and sets up the block unit in the mounting bracket front portion, the output and the block unit of power pack are connected.
Further, the fixed frame comprises a bottom plate and an upright post arranged on the bottom plate, and a lifting mechanism is arranged at the lower part of the bottom plate.
Further, the mounting frame of the rotary driving mechanism is hinged with the upright post of the fixed frame through a hinge.
Further, the power unit is a rotary oil cylinder, the maximum torque of the rotary oil cylinder is 30000N.m, and the rotating speed of the rotary oil cylinder is controlled to be 7-8 circles/min.
Further, the additional brake is connected with the tension sensor.
Further, the clamping unit comprises a clamping plate and a clamping block arranged on the clamping plate, and the clamping block is clamped with the protruding block on the additional brake disc.
The device has the specific working principle that the main driving disc type additional brake disc is driven to rotate by utilizing the rotary oil cylinder, so that the main driving additional brake is premilled, the defects of burrs, concave-convex and the like on the surfaces of the additional brake friction disc and the brake disc are eliminated, the surface lamination of the additional brake friction disc and the brake disc is better, and the friction fluctuation of the main driving brake disc after premilled is more stable. In the pre-grinding process, the brake disc is pressed, the maximum torque of the rotary oil cylinder is controlled to 30000N.m, the rotating speed of the rotary oil cylinder is controlled to 7-8 circles/min, after the pre-grinding is performed for 1 min, the friction force data of the brake disc is measured through the tension sensor, and the brake disc is stopped after the requirement is met.
The device has the advantages of simple structure, convenient operation, capability of rapidly realizing the pre-grinding of the main drive additional brake, high-precision detection, more stable output torque force, stable operation and small fluctuation when used in the later stage of the elevator.
