Abstract

The invention discloses an automatic winching device for a Yankee dryer. The automatic winching device for the Yankee dryer comprises the Yankee dryer with a main drive system, wherein a steel supportring coaxial with the Yankee dryer is arranged at the two axial sides of the Yankee dryer separately. The automatic winching device for the Yankee dryer further comprises a gear ring, a gear matchedwith the gear ring, a one-way clutch, a speed reduction motor, a frequency converter and a controller, wherein the gear ring sleeves the circumferential outer side of the steel support ring; the speedreduction motor is installed aside the Yankee dryer; the axis of an output shaft of the speed reduction motor is parallel to the axis of the Yankee dryer; the one-way clutch is arranged in a gear shaft hole; an outer ring of the one-way clutch is connected with the gear; the output shaft of the speed reduction motor is connected with an inner ring of the one-way clutch; the gear, the one-way clutch and the output shaft of the speed reduction motor are coaxial; the gear is engaged with the gear ring; the frequency converter is connected with the speed reduction motor; the frequency converter and the main drive system of the Yankee dryer are connected with the controller separately; and the speed reduction motor and the main drive system of the Yankee dryer form alternately-running controlinterlocking through the controller. The automatic winching device for the Yankee dryer is capable of automatically carrying out winching operation on the Yankee dryer in the case of halt of the maindrive system of the Yankee dryer.

Description

technical field [0001] The invention relates to an automatic disc cylinder device for a Yankee cylinder. Background technique [0002] The Yankee cylinder is an important drying equipment in the papermaking process. Large Yankee cylinders generally have a diameter of more than 5 meters, and the cylinder body is made of stainless steel, which is heavy. In order to prevent mechanical damage caused by local force on the transmission part when the Yankee cylinder is stopped, it is necessary to perform regular disk rotation during the shutdown of the Yankee cylinder. Now the Yankee cylinder is usually manually performed manually. Manual turning is carried out by means of tool prying and manual hoist pulling, which is very time-consuming and laborious. When shutting down, the main drive system of the Yankee cylinder is used to carry out the cylinder. It is necessary to open the main drive system of the paper machine, and at the same time open the thin oil system to lubricate th...
